Description

Technical Field

[0001] The present invention relates to a feeding container, and particularly to a feeding container used for containing items such as lipsticks.

Background Art

[0002] Containers for containing lipsticks and the like, which feed out the content when in use and retract it after use, are known in the art.

[0003] For example, Patent Document 1 discloses: a container body comprising a spiral cylinder provided with a circumferentially extending spiral hole, and a restricting cylinder rotatably mounted to the spiral cylinder; a containing cylinder portion disposed inside the container body and configured to contain a rod-shaped content inside, and comprising: wherein the containing cylinder portion has a guided projection inserted into the spiral hole and the guide hole, and relative rotation of the containing cylinder portion and the restricting cylinder is restricted by locking the guided projection to the guide hole, when the spiral cylinder and the restricting cylinder are rotated relatively, the guided projection slides in the spiral hole through the guide hole, so that the containing cylinder portion ascends or descends in the restricting cylinder to feed out or retract the rod-shaped content such as lipstick. The feeding container capable of the above operation is described.

[0004] The container described in Patent Document 1 is premised on being discarded after the content is used up.

[0005] In contrast, there has been proposed a feeding container having a cartridge (refill) for containing the content, wherein after the content is used up, the cartridge portion is discarded while portions other than the cartridge can be reused.

[0006] For example, Patent Document 2 discloses: a cylindrical main member having a first screw groove portion on an inner circumferential surface thereof; a cylindrical auxiliary member, wherein a sleeve cylinder having a longitudinal slit is erected from the inner side of a base cylinder portion disposed below the main member into the main member, and the auxiliary member is attached to the main member; A container for storing contents is fitted into the sleeve so as to be able to move up and down. It is equipped with, The base cylinder and the main member are rotatable integrally with respect to the sleeve portion. A second spiral groove portion is provided on the inner surface of the base cylinder portion, which is continuous with the first spiral groove portion and forms a series of spiral grooves. By using a feeding mechanism in which an engaging projection attached to the outer surface of the housing is inserted into the spiral groove through the vertical slit, the housing can be fed upward and retracted downward within the sleeve by rotating the base cylinder and the main member relative to the sleeve. The sub-member and the housing are formed as a single cartridge assembled to the main member. The cartridge can be removed from the main member and replaced while the engaging projection is inside the second screw groove. The dispensing container is described.

[0007] Such retractable containers have the advantage of allowing the parts other than the cartridge to be reused after the contents have been used up. They also have the advantage of allowing users to use multiple types of contents (for example, different colored lipsticks) by owning one part other than the cartridge and replacing it with a cartridge containing the desired contents each time.

[Modes for carrying out the invention]

[0017] The dispensing container of the present invention is The main body includes the inner fittings, inner frame, screw members, and base, Refill including inner tray and inner tube It is composed of.

[0018] The dispensing container of the present invention may further include a tail plug.

[0019] In the main body of the dispensing container of the present invention, The aforementioned internal component has a key-shaped projection for fixing the internal tray, and is fitted into the internal frame so as to be unable to rotate relative to it and so as to be able to move up and down. The aforementioned middle frame is fitted into the aforementioned hakama so as to be able to rotate relative to it but not be able to move up or down. The screw member has a screw track, The intermediate tool has an intermediate tool screw track that engages with the screw track of the screw member, or an intermediate tool projection that can slide along the screw track of the screw member. The screw member is fixedly attached to the hakama.

[0020] Furthermore, in the refill for the dispensing container of the present invention, The aforementioned inner tray has a protrusion for fixing the contents and a contents storage section for storing the contents, and is fitted into the inner cylinder so as to be unable to rotate relative to it and so as to be able to move up and down. The refill's inner cylinder is detachably fixed to the inner frame of the main body, thereby allowing the refill to be detachably assembled to the main body, When the refill is detachably assembled to the main body, the key-shaped projection for fixing the inner tray of the inner component and the projection for fixing the inner component of the inner tray engage with each other, thereby fixing the inner component and the inner tray relative to each other.

[0021] Furthermore, in the dispensing container of the present invention, when the skirt and the inner frame are rotated relative to each other, the screw track of the inner component or the protrusion of the inner component, which is fitted into the inner frame in a manner that prevents relative rotation, slides along the screw track of the screw member attached to the skirt, thereby allowing the inner component and the inner tray fixed thereto to be dispensed upward and retracted downward.

[0022] The contents stored in the retractable container of the present invention may be solid, rod-shaped pharmaceuticals, quasi-drugs, cosmetics, etc. Specifically, the contents may be, for example, lipstick, lip balm, eyeshadow, eyebrow pencil, blush, concealer, foundation, etc., and are typically lipstick.

[0023] The retractable container of the present invention can also be applied as a container for solid, rod-shaped stationery items. Examples of such stationery items include erasers, glue, crayons, and pastels.

[0024] 《Main body》 The main body includes the inner components, inner frame, screw members, and base.

[0025] <Filling> The inner part may have a roughly cylindrical shape and include a key-shaped projection for fixing the inner tray, an inner part screw track or an inner part projection, and may further include a projection for preventing the inner part from rotating, a vertical slit in the inner part, etc.

[0026] The key-shaped projection for fixing the inner tray engages with the projection for fixing the inner contents of the refill's inner tray when the refill is attached to the body of the dispensing container of the present invention, thereby having the function of relatively fixing the inner contents and the inner tray together.

[0027] The key-shaped projection for securing the inner tray may be, for example, an inverted L-shaped relief projection formed on the outer surface of the cylindrical inner container near the upper end, or an inverted L-shaped projection that protrudes upward from the circumference of the upper end of the cylindrical inner container. Here, "inverted L-shape" refers to a shape composed of a straight section extending upward and a straight section extending circumferentially from the upper end of the said straight section.

[0028] The inner container may have only one key-shaped projection for securing the inner tray, or it may have two or more. When the inner container has two or more key-shaped projections for securing the inner tray, these key-shaped projections may be evenly arranged along the circumference on the outer surface of the cylindrical inner container or on the circumference near the upper end. The inner container in the body of the dispensing container of the present invention typically has two to four key-shaped projections for securing the inner tray.

[0029] The internal screw track engages with the screw track of the screw member and, when the internal tool and the screw member are rotated relative to each other, has the function of moving the internal tool (and the internal plate fixed relative to the internal tool) up and down relative to the screw member (and the internal frame and base fixed relative to it).

[0030] The internal screw raceway may be either a male or female thread, as long as it can be screwed into the screw raceway of the screw member. When the screw raceway of the screw member is a male thread, the internal screw raceway may be, for example, a female thread formed on the inner circumferential surface of a cylindrical internal component.

[0031] The central component projection is a projection that can slide along the screw thread track of the screw member, and when the central component and the screw member are rotated relative to each other, it has the function of raising and lowering the central component (and the central plate fixed relative to the central component) relative to the screw member (and the central frame and base fixed relative to it).

[0032] The internal component projection may be formed anywhere on the internal component, as long as it can slide along the threaded raceway of the screw member. When the threaded raceway of the screw member is a female thread, the internal component projection may be, for example, one or more projections formed on the outer circumferential surface of a cylindrical internal component. The shape of the internal component projection is arbitrary, as long as it can slide along the threaded raceway of the screw member.

[0033] The inner container may have only one inner container protrusion, or it may have two or more. When the inner container has two or more inner container protrusions, these protrusions may be evenly arranged along the circumference on the inner or outer circumferential surface of the cylindrical inner container. When the inner container in the body of the dispensing container of the present invention has inner container protrusions, the number of such protrusions may typically be between two and four.

[0034] The inner container of the dispensing container of the present invention may selectively have an inner container screw track and an inner container protrusion depending on the configuration of the screw track of the screw member. For example, when the screw track of the screw member is a male thread, the inner container may have one or more of the following: a female screw-shaped inner container screw track formed on the inner circumferential surface of the cylindrical inner container, and an inner container protrusion which is a projection formed on the inner circumferential surface of the cylindrical inner container. When the screw track of the screw member is a female thread, the inner container may have an inner container protrusion which is a projection formed on the outer circumferential surface of the cylindrical inner container.

[0035] The inner container of the dispensing container of the present invention may have a protrusion for preventing the inner container from rotating. This protrusion for preventing the inner container from rotating may be fitted into a vertical slit in the inner frame, which the inner frame may optionally have, when the inner container is inserted into the inner frame. With this configuration, the inner container is fitted into the inner frame in a way that prevents relative rotation and allows it to move up and down.

[0036] The protrusion for preventing the internal component from rotating may be a protrusion formed on the outer surface of the cylindrical internal component. The shape of the protrusion for preventing the internal component from rotating may have a width and protruding height sufficient to fit into the vertical slit of the internal frame, and a length sufficient to allow smooth up and down movement within the vertical slit of the internal frame, and the remaining shape may be arbitrary.

[0037] The inner container may have only one protrusion for preventing the inner container from rotating, or it may have two or more. When the inner container has two or more protrusions for preventing the inner container from rotating, these protrusions may be evenly arranged along the circumference on the outer surface of the cylindrical inner container. When the inner container in the body of the dispensing container of the present invention has protrusions for preventing the inner container from rotating, the number of such protrusions may typically be between two and four.

[0038] When the internal component has a projection on its outer surface, this projection may also function as a projection for preventing the internal component from rotating. In this case, when fitted into the vertical slit of the internal frame, the internal component projection protrudes from the outer surface of the internal frame and slides along the screw track of the screw member, which is a female screw.

[0039] The internal component may be formed as a single unit, or it may be composed of two or more parts combined together. In the latter case, the internal component may consist of, for example, two cylindrical parts of different sizes: an external internal component portion and an internal internal threaded portion. The external internal component portion may have key-shaped protrusions for fixing the internal tray and protrusions for preventing the internal component from rotating on its outer surface, and the internal internal threaded portion may have a threaded track on its inner surface.

[0040] The inner component vertical slit is a vertical notch formed on the outer surface of the cylindrical inner component. The inner component in the body of the dispensing container of the present invention may or may not have this inner component vertical slit.

[0041] <Center frame> The inner frame of the dispensing container of the present invention is fitted into the base so as to be able to rotate relative to it but not so as to move up or down.

[0042] The inner frame may have a roughly cylindrical shape and may include features such as vertical slits, protrusions for fixing the inner cylinder, a fitting part for setting the position of a screw member, an engaging part for fixing a hook, and claws for preventing the inner cylinder from rotating.

[0043] The vertical slits in the inner frame have the function of controlling the inner component so that it cannot rotate relative to the inner component and can move up and down within the inner frame, by fitting the protrusions for preventing the inner component from rotating into the inner frame when the inner component is inserted into the inner frame.

[0044] The vertical slit in the inner frame may be a straight slit extending upward from the lower end of the cylindrical inner frame. The width of the vertical slit in the inner frame may be such that a protrusion for preventing the inner component from rotating can be fitted into it, and that smooth vertical movement is possible. The length of the vertical slit in the inner frame defines the vertical movement of the inner component, the inner tray fixedly attached thereto, and the contents stored in the inner tray. Therefore, the length of the vertical slit in the inner frame may be approximately the same as the length of the contents that are dispensed.

[0045] The vertical slit in the middle frame may be formed by cutting out a portion of the peripheral wall of the middle frame into a predetermined shape, resulting in a through-type configuration where the vertical slit portion of the middle frame does not have a peripheral wall; or by thinning a portion of the inner peripheral surface of the peripheral wall of the middle frame into a predetermined shape, resulting in a thin-walled configuration where the vertical slit portion of the middle frame also has a peripheral wall; or by forming a thin-walled configuration where a portion of the vertical slit portion of the middle frame does not have a peripheral wall, and the remaining portion of the vertical slit portion of the middle frame has a through-type configuration where a peripheral wall is present.

[0046] The inner frame of the dispensing container of the present invention may have the same number of vertical slits as the number of protrusions on the inner container that prevent the inner container from rotating, located at positions corresponding to each of the protrusions that prevent the inner container from rotating.

[0047] The protrusions on the inner frame for fixing the inner cylinder engage with the L-shaped slits for fixing the inner frame, which the inner cylinder of the refill may optionally have, when the refill is assembled to the body of the retractable container, thereby detachably fixing the inner cylinder to the inner frame. This function allows the refill to be detachably attached to the body of the retractable container of the present invention.

[0048] The projection for fixing the inner cylinder may be a projection formed on the inner circumferential surface of the cylindrical inner frame, near the upper end. The projection for fixing the inner cylinder may have any shape as long as it is able to slide vertically within the L-shaped slit for fixing the inner frame and can engage laterally with the L-shaped slit for fixing the inner frame. For example, the projection for fixing the inner cylinder may be a hemispherical projection.

[0049] The inner frame may have only one or more protrusions for fixing the inner cylinder. When the inner frame has two or more protrusions for fixing the inner cylinder, these protrusions may be evenly arranged along the circumference on the inner surface of the cylindrical inner frame. When the inner frame of the dispensing container body of the present invention has protrusions for fixing the inner cylinder, the number of such protrusions may typically be between two and four.

[0050] The screw member position setting inner frame fitting portion receives the screw member position setting screw member fitting portion that the screw member may have, and has the function of holding the inner frame so that it can rotate relative to the screw member (and the frame to which it is fixedly attached) but cannot move up or down.

[0051] The inner frame fitting portion for setting the position of the screw member may be a circumferentially extending slit formed in the portion of the peripheral wall of the cylindrical inner frame that is close to the lower end.

[0052] The intermediate frame fitting portion for setting the position of the screw member may be configured such that a portion of the peripheral wall of the intermediate frame is cut out in a predetermined shape, and the portion of the intermediate frame fitting portion for setting the position of the screw member does not have a peripheral wall; or a portion of the inner peripheral surface of the peripheral wall of the intermediate frame is thinned in a predetermined shape, and the portion of the intermediate frame fitting portion for setting the position of the screw member also has a peripheral wall; or a portion of the intermediate frame fitting portion for setting the position of the screw member does not have a peripheral wall, and the remaining portion of the intermediate frame fitting portion for setting the position of the screw member has a peripheral wall.

[0053] The inner frame may have only one or more screw member positioning inner frame fitting parts. When the inner frame has two or more screw member positioning inner frame fitting parts, these screw member positioning inner frame fitting parts may be evenly arranged along the circumference on the peripheral wall of the cylindrical inner frame. When the inner frame of the dispensing container body of the present invention has screw member positioning inner frame fitting parts, the number thereof may typically be between two and four.

[0054] The hook-fixing engagement portion engages with the inner frame fixing engagement portion of the hook, which may be optionally present on the body of the dispensing container of the present invention, and has the function of holding the inner component in the space formed by the inner frame and the hook in a manner that prevents relative rotation and allows for vertical movement. Furthermore, as will be described later, since the hook is mounted inside the base in a manner that allows for relative rotation and prevents vertical movement, the inner frame is held in a manner that allows for relative rotation and prevents vertical movement with respect to the screw member fixedly attached to the base.

[0055] The hook-fastening engagement portion may be a recessed portion or a slit extending in the circumferential direction, formed in the portion of the peripheral wall of the cylindrical inner frame that is close to the lower end.

[0056] The inner frame may have only one fastening engagement portion, or it may have two or more. When the inner frame has two or more fastening engagement portions, these fastening engagement portions may be evenly arranged along the circumference on the peripheral wall of the cylindrical inner frame. When the inner frame of the dispensing container body of the present invention has fastening engagement portions, the number of such portions may typically be between two and four.

[0057] The inner frame may have both an inner frame fitting portion for setting the position of the screw member and an engaging portion for fixing the hook. However, in order for the inner frame to function as being able to rotate relative to the screw member and being unable to move up or down, it is sufficient to have either the inner frame fitting portion for setting the position of the screw member or the engaging portion for fixing the hook. However, if the inner frame has an engaging portion for fixing the hook and does not have an inner frame fitting portion for setting the position of the screw member, it is desirable that the body of the dispensing container be equipped with a hook.

[0058] The inner frame claw portion for preventing the inner cylinder from rotating engages with the inner cylinder engagement portion (or an L-shaped slit for fixing the inner frame that also serves this function) optionally present on the inner cylinder of the refill for the dispensing container of the present invention, thereby suppressing the relative rotation between the inner cylinder and the inner frame. Due to these engagements, when the inner frame and the base are rotated relative to each other to extend the inner components upward and retract them downward, the inner cylinder and the inner frame do not rotate relative to each other. Therefore, the extension of the inner components, which are fitted into the inner frame in a manner that prevents relative rotation, and the inner tray fixed thereto, can be performed efficiently and smoothly.

[0059] The claw portion of the inner frame for preventing the inner cylinder from rotating may be a flexible claw-shaped projection formed on the circumferential wall of the cylindrical inner frame near the axial middle. Specifically, for example, it may have a projection that protrudes inward from the inner frame near the tip of a "Π" (pi) shaped notch formed on the circumferential wall of the cylindrical inner frame (the horizontal line above the "Π").

[0060] The inner frame may have only one inner frame claw portion for preventing the inner cylinder from rotating, or it may have two or more. When the inner frame has two or more inner frame claw portions for preventing the inner cylinder from rotating, these inner frame claw portions for preventing the inner cylinder from rotating may be evenly arranged along the circumference on the peripheral wall of the cylindrical inner frame. When the inner frame of the body of the dispensing container of the present invention has inner frame claw portions for preventing the inner cylinder from rotating, the number of such portions may typically be two to four.

[0061] <Screw components> The screw member in the body of the dispensing container of the present invention is fixedly attached to the base. This screw member has a screw member screw track and may have a screw member fitting part for setting the screw member position, a screw member engaging part for fixing the screw member, and so on.

[0062] The functions of the screw threads and screw raceways are as follows:

[0063] As described above, the inner component is fitted into the inner frame so as to be unable to rotate relative to it and to be able to move up and down. Furthermore, when a refill is attached to the body of the dispensing container of the present invention, the key-shaped projection for fixing the inner tray of the inner component and the projection for fixing the inner component on the inner tray engage with each other, and the inner component is fixed relative to the inner tray of the refill.

[0064] When the base and the aforementioned middle frame are rotated relative to each other, the middle screw track or protrusion of the middle component slides along the screw track of the screw member attached to the base, thereby allowing the middle component and the middle plate fixed thereto to be extended upward and retracted downward.

[0065] The screw threads of the screw member can be either male or female threads.

[0066] When the screw thread of the screw member is a male thread, the screw member may have a disc-shaped screw member positioning screw member fitting portion, a screw shaft extending upward from the center of the screw member positioning screw member fitting portion, and a screw thread of the screw member formed on the outer circumferential surface of the screw shaft.

[0067] The screw member positioning screw member fitting portion is inserted into the screw member positioning inner frame fitting portion of the inner frame, and has the function of holding the inner frame so that it can rotate relative to the screw member (and the skirt that holds it fixedly) but cannot move up or down.

[0068] The screw member positioning screw member fitting portion may have a diameter and thickness that allows it to be inserted into the screw member positioning inner frame fitting portion of the inner frame and rotate smoothly in order to perform the above function.

[0069] The screw shaft may be a rod-shaped body extending upward from the center of the screw member fitting portion for positioning the screw member. The length of this screw shaft defines the vertical movement of the inner container, the inner tray fixedly attached thereto, and the contents stored in the inner tray. Therefore, the length of the screw shaft may be approximately the same as the length of the contents being dispensed.

[0070] The screw shaft is designed so that the screw raceway formed on its outer surface engages with the screw raceway of the internal component, thereby raising and lowering the internal component. Therefore, the screw shaft may have a diameter that allows for the formation of a screw raceway having this function.

[0071] The threaded raceway of the male threaded screw member engages with the threaded raceway of the female threaded insert, thereby performing the function of raising and lowering the insert. The configuration of the threaded raceway of the screw member is arbitrary as long as this function is performed. The threaded raceway of the screw member may be formed along the entire length of the screw shaft, or it may be formed only along a part of the length of the screw shaft. Furthermore, the threaded raceway of the screw member may be a continuous threaded raceway, or it may be interrupted in the middle, as long as it can engage with the threaded raceway of the insert.

[0072] The screw member fixing screw member engaging portion engages with the screw member fixing hakama engaging portion of the hakama, and has the function of fixing the screw member to the hakama. This screw member fixing screw member engaging portion may be provided on the screw member when the screw raceway of the screw member is a male thread.

[0073] The screw member engagement portion for fixing the screw member may be, for example, a key-shaped projection formed on the bottom surface of the screw member fitting portion for positioning the screw member.

[0074] The screw member may have only one screw member fixing engagement portion, or it may have two or more. When the screw member has two or more screw member fixing engagement portions, these screw member fixing engagement portions may be evenly arranged symmetrically on the bottom surface of the disc-shaped screw member positioning screw member fitting portion. When the screw member in the body of the dispensing container of the present invention has screw member fixing engagement portions, the number of such portions may typically be two to four.

[0075] When the threaded raceway of the screw member is an internal thread, the screw member may have a cylindrical shape, and the threaded raceway of the screw member may be formed on the inner circumferential surface of the cylindrical screw member.

[0076] The threaded raceway of the threaded member, which is an internal thread, has the function of raising and lowering the internal component by allowing the internal component's projection to slide along it. The configuration of the threaded raceway of the threaded member is arbitrary as long as this function can be performed. The threaded raceway of the threaded member may be formed over the entire axial length of the threaded member, or it may be formed over only a part of the axial length of the threaded member. Furthermore, the threaded raceway of the threaded member may be a continuous raceway, or it may be interrupted in the middle, as long as the internal component's projection can slide along it.

[0077] <Hakama> The base of the dispensing container of the present invention has the function of fixing the screw member to it and making it easier for the user to rotate the screw member relative to the inner container, etc.

[0078] The hakama may have a bottomed, cylindrical shape.

[0079] The base may have, for example, a base engagement portion for fixing the screw member in order to securely attach the screw member. This base engagement portion is intended to engage with the screw member engagement portion of the screw member to perform the above function. Therefore, the base engagement portion for fixing the screw member may be, for example, a key-shaped projection formed on the inside of the bottom surface.

[0080] The base may have the same number of base engagement portions for fixing the screw member as the number of screw member engagement portions for fixing the screw member of the screw member, at positions corresponding to each of the screw member engagement portions for fixing the screw member.

[0081] <Hook> A hook may be used to hold the inner component in the space formed by the inner frame and the hook so as to be unable to rotate relative to it and to be able to move up and down.

[0082] The hook may have a disc-shaped hook base and an engagement portion for fixing the inner frame formed on the hook base. This engagement portion for fixing the inner frame engages with the engagement portion for fixing the hook on the inner frame, and has the function of making the space formed by the inner frame and the hook permanent. Therefore, the engagement portion for fixing the inner frame may be a key-shaped projection that protrudes upward from the hook base and can engage with the engagement portion for fixing the hook on the inner frame.

[0083] The hook may have the same number of engaging parts for fixing the inner frame as the number of engaging parts for fixing the hook on the inner frame, each of which is located at a position corresponding to the engaging part for fixing the inner frame.

[0084] The hook may be attached to the base so as to be rotatable relative to it but not so as to be able to move up or down. With this attachment method, the set of base and screw member is rotatable relative to the set of middle frame and hook, but not so as to move up or down. The relative rotation between the screw member and the middle frame causes the screw track or protrusion of the middle component, which is held in a position within the middle frame so as not to rotate relative to it, to slide along the screw track of the screw member, thereby allowing the middle component and the middle plate fixed thereto to be fed upward and retracted downward.

[0085] <Outer cylinder> The dispensing container of the present invention may have an outer cylinder. The outer cylinder surrounds the outer surface of the inner frame and has the function of facilitating the user to rotate the inner frame relative to the base (and the screw member fixedly attached thereto).

[0086] Therefore, the outer cylinder may be cylindrical in shape that can surround the outer surface of the inner frame, and the inner frame may be fixedly inserted into the outer cylinder.

[0087] Refill The refill for the dispensing container of the present invention includes an inner tray and an inner cylinder. The refill may further have a temporary stopper.

[0088] <Medium Plate> The inner tray may have a roughly cylindrical shape and have a compartment for storing contents and a protrusion for securing the contents. It may also have an inner tray engagement part for preventing the inner tray from rotating, an inner tray divider, a protrusion for securing the contents, etc.

[0089] The contents storage compartment is a space for storing and holding the lower end of a rod-shaped contents (e.g., lipstick). The upper end of the contents protrudes upward from the contents storage compartment and is exposed.

[0090] The inner tray may have an inner tray divider. The internal space of the cylindrical inner tray may be divided vertically by this inner tray divider, and the space above the inner tray divider may be the contents storage area. The inner tray divider may have one or more contents filling air vents. These contents filling air vents are holes that penetrate the inner tray divider and have the function of releasing air from the lower part of the contents storage area to the outside of the contents storage area when filling the inner tray with contents, making it easier to fill the contents storage area with contents.

[0091] The inner tray may further have a protrusion for securing the contents that protrudes inward (towards the contents storage area) from the inner surface of the inner tray's peripheral wall. The contents-securing protrusion has the function of biting into the contents filled in the contents storage area and suppressing relative movement between the contents and the inner tray.

[0092] The protrusion for fixing the inner container engages with the key-shaped protrusion for fixing the inner tray of the inner container in the main body when the refill is attached to the main body of the dispensing container of the present invention, and has the function of fixing the inner container and the inner tray relative to each other.

[0093] The protrusion for securing the inner component may be, for example, a relief-like projection formed on the outer surface of the cylindrical inner tray near its lower end. The shape of the protrusion for securing the inner component is arbitrary as long as it can engage with the key-shaped protrusion for securing the inner tray of the inner component, and may be, for example, a rectangular or hemispherical projection.

[0094] The inner tray rotation prevention engaging portion engages with the inner cylinder rotation prevention engaging portion of the inner cylinder, and has the function of relatively fixing the inner tray and the inner cylinder until the refill is attached to the main body.

[0095] However, after the refill is attached to the main body, the inner tray is fixed to the inner component of the main body via a protrusion for fixing the inner component and a key-shaped protrusion for fixing the inner tray, and the inner cylinder is fixed to the inner frame of the main body via an L-shaped slit for fixing the inner frame and a protrusion for fixing the inner frame. Therefore, after the refill is attached to the main body, the practical benefit of directly fixing the inner tray and the inner component is reduced.

[0096] Furthermore, in the dispensing container of the present invention, when the base and the inner frame are rotated relative to each other, the inner tray is expected to move vertically relative to the inner cylinder to be dispensed or retracted. Therefore, it is desirable that the fixing of the inner tray and the contents be temporary.

[0097] From these perspectives, the intermediate plate engagement portion for preventing the intermediate plate from rotating may be, for example, a projection formed in a region of the intermediate plate that is given radial flexibility, surrounded by two notches formed on the outer circumferential surface of the cylindrical intermediate plate near its lower end. With this configuration, when the intermediate plate is extended relative to the intermediate cylinder, the region where the intermediate plate engagement portion for preventing the intermediate plate from rotating is formed will bend radially inward due to its flexibility, the engagement between the intermediate plate engagement portion for preventing the intermediate plate from rotating and the intermediate cylinder engagement portion for preventing the intermediate plate from rotating will be released, and the intermediate plate will be able to move up and down relative to the intermediate cylinder.

[0098] The inner tray may have only one key-shaped projection for fixing the inner tray, or it may have two or more. When the inner tray has two or more inner tray engagement parts for preventing the inner tray from rotating, these inner tray engagement parts for preventing the inner tray from rotating may be evenly arranged along the circumference on the outer surface of the cylindrical inner tray. The inner tray in the body of the dispensing container of the present invention typically has two to four key-shaped projections for fixing the inner tray.

[0099] In the refill for the dispensing container of the present invention, the inner tray is fitted into the inner cylinder so as not to rotate relative to it and so as to be able to move up and down.

[0100] <Middle tube> The inner cylinder has a roughly cylindrical shape, has an L-shaped slit for fixing the inner frame, and may also have an inner cylinder engagement part for preventing the inner plate from rotating, an inner cylinder engagement part for preventing the inner cylinder from rotating, etc.

[0101] The inner tube has a roughly cylindrical shape. This cylindrical shape may have an upper end that is cut at an angle. This configuration improves the user experience when the contents are, for example, lipstick.

[0102] The L-shaped slit for fixing the inner frame engages with a protrusion for fixing the inner cylinder, which may be optionally present on the inner frame of the dispenser body, when the refill is assembled to the dispenser body, thereby detachably fixing the inner cylinder to the inner frame. This function allows the refill to be detachably attached to the body of the dispenser body of the present invention.

[0103] The L-shaped slit for fixing the inner frame may be an L-shaped notch consisting of a straight vertical notch extending upward from the lower end of the inner cylinder and a straight horizontal notch extending circumferentially from the upper end of the vertical notch.

[0104] When inserting a refill into the main body, the protrusion for fixing the inner cylinder of the inner frame slides upward from below through the vertical notch of the L-shaped slit for fixing the inner frame of the inner cylinder. After the protrusion for fixing the inner cylinder reaches the upper end of the vertical notch of the L-shaped slit for fixing the inner frame, by rotating the refill and the main body relative to each other, the protrusion for fixing the inner cylinder enters and engages with the horizontal notch of the L-shaped slit for fixing the inner frame, and the inner cylinder is fixed to the inner frame.

[0105] The inner cylinder of the refill for the dispensing container of the present invention may have the same number of L-shaped slits for fixing the inner frame as the number of protrusions for fixing the inner cylinder that the inner frame has, located at positions corresponding to each of the protrusions for fixing the inner cylinder.

[0106] The inner cylinder engagement part for preventing the inner tray from rotating engages with the inner tray engagement part for preventing the inner tray from rotating on the inner tray, and has the function of relatively fixing the inner tray and the inner cylinder until the refill is attached to the main body.

[0107] The inner cylinder engagement portion for preventing the inner tray from rotating may be, for example, a hole formed near the lower end of a cylindrical inner cylinder. The shape and size of this hole may be such that it can easily engage with the inner tray engagement portion for preventing the inner tray from rotating, and can also be released from the container.

[0108] The inner cylinder of the refill for the dispensing container of the present invention may have the same number of inner cylinder engagement parts for preventing the rotation of the inner tray as the inner tray engagement parts for preventing the rotation of the inner tray, located at positions corresponding to each of the inner tray engagement parts for preventing the rotation of the inner tray.

[0109] The inner cylinder rotation prevention engagement portion engages with an inner cylinder rotation prevention claw portion optionally present on the inner frame of the main body of the dispensing container of the present invention, thereby suppressing the relative rotation of the inner cylinder and the inner frame. This allows for efficient and smooth upward and downward dispensing of the inner utensils and inner tray when the base and inner frame are rotated relative to each other.

[0110] The inner cylinder rotation prevention engagement portion may be a recessed portion (hole) formed in the peripheral wall of a cylindrical inner frame so as to enable reversible engagement with the inner frame rotation prevention claw portion of the inner frame in the body of the dispensing container.

[0111] The inner cylinder in the refill of the dispensing container of the present invention may have the same number of inner cylinder rotation prevention inner cylinder engagement parts as the inner frame rotation prevention inner frame claw parts, located at positions corresponding to each of the inner cylinder rotation prevention inner frame claw parts.

[0112] In the refill for the dispensing container of the present invention, the inner cylinder does not have an inner cylinder engagement part for preventing the inner cylinder from rotating, and the L-shaped slit for fixing the inner frame may be provided with the function of an inner cylinder engagement part for preventing the inner cylinder from rotating. In this case, the L-shaped slit for fixing the inner frame has both the function of fixing the inner cylinder to the inner frame so that it can be attached to and detached, and the function of suppressing the rotation of the inner frame.

[0113] <Temporary stopper> The refills for the dispensing container of the present invention may have a temporary stopper to protect the contents during transport, during sales and display, and after the user purchases the container and before attaching it to the main body, or to protect the contents of unused refills when using multiple types of contents. This temporary stopper may be one or more of the following: a lid that covers the top of the inner cylinder, and a lid that covers the bottom of the inner cylinder.

[0114] After the user has assembled the refill into the main unit and begun using the contents, the temporary stopper may be discarded, or it may be kept to protect the contents of unused refills when using multiple types of contents.

[0115] 《tail plug》 In addition to the main body and refill described above, the retractable container of the present invention may further include a tail cap.

[0116] The end cap serves to protect the contents after the user has assembled the refill into the main body and begun using the contents. After purchasing a refill with a temporary stopper, the user assembles it into the main body to create a retractable container, discards the temporary stopper, and attaches the end cap. When using, the end cap is removed from the retractable container, and the base and inner frame (or the outer cylinder that permanently covers the inner frame) are rotated relative to each other to extend the inner container, the inner tray fixed thereto, and the contents stored in the inner tray for use. After use, the base and inner frame are rotated relative to each other in the opposite direction to extend the contents, the end cap is attached, and the container is stored until the next use.

[0117] The end cap may be a cylindrical body with a top that can cover the inner tube. The bottom of the end cap may reach the upper end of the skirt or its vicinity when the refill is assembled to the main body.

[0118] 《Installing and removing refills from the main unit》 In the retractable container of the present invention, the refill can be detachably attached to the main body. That is, in the retractable container of the present invention, it is easy to attach the refill to the main body and to remove the refill from the main body.

[0119] When assembling the refill into the main body, as described above, first insert the refill into the main body. At this time, the protrusion for fixing the inner cylinder on the inner frame of the refill slides from bottom to top through the vertical notch of the L-shaped slit for fixing the inner frame of the inner cylinder of the main body. Then, after the protrusion for fixing the inner cylinder reaches the upper end of the vertical notch of the L-shaped slit for fixing the inner frame, by rotating the refill and the main body relative to each other, the protrusion for fixing the inner cylinder enters into the horizontal notch of the L-shaped slit for fixing the inner frame and engages, and the inner cylinder is fixed to the inner frame.

[0120] Furthermore, when the protrusion for fixing the inner cylinder of the inner frame and the L-shaped slit for fixing the inner frame of the inner cylinder engage, the key-shaped protrusion for fixing the inner tray of the main body and the protrusion for fixing the inner tray of the refill engage simultaneously, thereby fixing the inner component and the inner tray relative to each other.

[0121] Since the engagement between the protrusion for fixing the inner cylinder of the inner frame and the L-shaped slit for fixing the inner frame of the inner cylinder, and the engagement between the key-shaped protrusion for fixing the inner tray of the inner component and the protrusion for fixing the inner component of the inner tray, are both reversible, the refill can be attached to the main body in a detachable manner.

[0122] 《Feedback mechanism》 In a retractable container after the refill has been assembled into the main body, the inner container, the inner tray fixed thereto, and the contents stored in the inner tray can be extended and retracted by rotating the base and the inner frame (or the outer cylinder that permanently covers the inner frame) relative to each other.

[0123] In other words, a screw member having a screw track is fixedly attached to the base. A refill cylinder is fixedly assembled to the inner frame. A component having a screw track or a protrusion is further fitted into the inner frame so as to be unable to rotate relative to it but able to move up and down. Relative rotation is possible between the inner frame and the screw member, but relative movement up and down is not possible. Therefore, similarly, relative rotation is possible between the inner frame and the base to which the screw member is fixedly attached, but relative movement up and down is not possible.

[0124] On the other hand, the inner container has a refill tray permanently attached to it, and the tray contains a rod-shaped contents.

[0125] Therefore, when the base of the main body and the inner frame (or the outer cylinder that permanently covers the inner frame) are rotated relative to each other, the screw member fixedly attached to the base and the internal component, which is fitted into the inner frame in a way that prevents relative rotation but allows for vertical movement, rotate relative to each other. As a result, the internal component's screw track or protrusion slides along the screw member's screw track, causing the internal component to move up and down relative to the base, screw member, inner frame, and inner cylinder. Consequently, the internal tray, which is fixedly assembled to the internal component, also moves up and down with the internal component, and the contents contained in the internal tray also move up and down. Therefore, the tip of the contents protruding above the internal tray is extended to the top of the inner frame and retracted downwards.

[0126] According to another aspect of the present invention, Including the inner tray and inner cylinder, The aforementioned inner tray has a protrusion for engaging the inner container and a portion for storing the contents. It is fitted into the aforementioned inner cylinder so as not to rotate relative to it and so as to be able to move up and down, The dispensing container used in the present invention Refills for the retractable container are provided.

[0127] According to yet another aspect of the present invention, Including the inner fittings, inner frame, screw members, and base, The aforementioned internal component has a key-shaped projection for fixing the internal tray, and is fitted into the internal frame so as to be unable to rotate relative to it and so as to be able to move up and down. The aforementioned middle frame is fitted into the aforementioned hakama so as to be able to rotate relative to it but not be able to move up or down. The screw member has a screw track, The intermediate tool has an intermediate tool screw track that engages with the screw track of the screw member, or an intermediate tool projection that can slide along the screw track of the screw member. The screw member is fixedly attached to the hakama, The dispensing container used in the present invention The main body of the dispensing container is provided.

[0128] Embodiment 1 Figures 1 to 21 show diagrams illustrating the form of the retractable container of Embodiment 1. Of these, Figures 1 to 11 relate to the main body, Figures 12 to 15 relate to the refill, Figures 16 to 20 relate to the assembly of the refill into the main body, and Figure 21 relates to the retractable mechanism.

[0129] <Main body> Figures 1 and 2 show the internal components of the dispensing container body of Embodiment 1. Figure 1(A) is a perspective view of the internal components, and Figure 1(B) is a cross-sectional view taken along line AA in Figure 1(A). Figure 2(A) is a top view of the internal components, Figure 2(B) is a bottom view, Figure 2(C) is a front view, and Figure 2(D) is a right side view.

[0130] The internal component (110) shown in Figures 1 and 2 has a roughly cylindrical shape and includes a key-shaped projection (121) for fixing the internal tray, an internal component screw track (131), and a projection (122) for preventing the internal component from rotating.

[0131] The key-shaped projections (121) for securing the inner tray in the inner part (110) shown in Figures 1 and 2 are inverted L-shaped relief projections formed on the outer surface of the inner part (110) near the upper end. The inner part (110) has two key-shaped projections (121) for securing the inner tray, located near the upper end of the cylindrical outer surface, at opposing positions with respect to the center of the circumference.

[0132] The internal screw raceway (131) of the internal tool (110) is a series of female threads formed on the inner circumferential surface of the cylindrical internal tool (110).

[0133] The protrusions (122) for preventing the rotation of the inner part (110) are elongated projections formed on the outer surface near the lower end. The inner part (110) has two protrusions (122) for preventing the rotation of the inner part (110) located opposite each other across the center of the circumference near the lower end of the cylindrical outer surface.

[0134] The internal component may be constructed as a single part, or it may be composed of two parts, for example, an outer periphery of the internal component and an internal threaded portion of the internal component. Figure 3 shows a perspective view of the outer periphery (120) and internal threaded portion (130) of the internal component (110). In the embodiment of Figure 3, the outer periphery (120) of the internal component has a substantially cylindrical shape and has a key-shaped projection (121) for fixing the internal tray and a projection (122) for preventing the internal component from rotating on its outer surface. The internal threaded portion (130) also has a substantially cylindrical shape and is fitted inside the outer periphery (120), and has an internal threaded track (131).

[0135] The internal threaded portion (130) of the internal component is fixedly fitted into the outer circumference (120) of the internal component. In the outer circumference (120) of the internal component shown in Figure 3, the internal threaded portion (130), which has a smooth outer surface, is fitted into the outer circumference (120) of the internal component, which has a smooth inner surface.

[0136] In an alternative configuration where the internal fitting (110) is composed of an outer peripheral portion (120) and an internal threaded portion (130), a double-threaded structure is provided in which the internal threaded portion (130) has a male threaded raceway on its outer peripheral surface and the outer peripheral portion (120) has a female threaded raceway on its inner peripheral surface. In this case, the length of the vertical slit (141) of the inner frame can be shortened, and the strength of the inner frame can be maintained at a high level.

[0137] In other words, if the vertical slit (141) of the inner frame is short, when the inner component rises by rotating the base of the main body and the inner frame relative to each other, the protrusion (122) for preventing the inner component from rotating on the outer circumference (120) of the inner component comes into contact with the upper end of the vertical slit (141) of the inner frame, preventing the outer circumference (120) of the inner component from rising any further. However, if the inner component (110) has a double screw structure, when the rise of the outer circumference (120) of the inner component is prevented, the male screw track on the outer circumference surface of the inner component's internal screw section (130) slides along the female screw track on the inner circumference surface of the outer circumference surface (120), allowing only the internal screw section (130) to continue rising, and the inner tray (210) and its contents can be further dispensed.

[0138] Figure 4 shows the inner frame of the dispensing container body of Embodiment 1. Figure 4(A) is a perspective view of the inner frame, Figure 4(B) is a cross-sectional view of Figure 4(A) along line AA, and Figure 4(C) is a cross-sectional view along line BB.

[0139] The middle frame (140) shown in Figure 4 has a roughly cylindrical shape. The middle frame (140) in Figure 4 is formed with the upper part being slightly thicker than the lower part, and has a middle frame step (145) near the center in the axial direction. However, this embodiment is not essential.

[0140] The inner frame (140) in Figure 4 has a vertical slit (141), a protrusion (142) for fixing the inner cylinder, an inner frame fitting part (143) for setting the position of the screw member, and an inner frame claw part (144) for preventing the inner cylinder from rotating.

[0141] In Figure 4, the vertical slit (141) of the central frame (140) is a straight slit extending upward from the lower end of the cylindrical central frame. The width of the vertical slit (141) is slightly larger than the width of the protrusion (122) for preventing the rotation of the central component (110). The vertical slit (141) is composed of a thinned-wall portion (141a) of the vertical slit (141) located above the vertical slit (141) and formed by thinning a portion of the inner surface of the peripheral wall of the central frame, and a penetrating portion (141b) of the vertical slit (141) located below the vertical slit (141) and formed by cutting out a portion of the inner surface of the peripheral wall of the central frame and allowing it to pass through.

[0142] The length of the central frame vertical slit (141) (the sum of the length of the thin-walled portion (141a) and the through portion (141b) of the central frame vertical slit) is approximately 90% of the length of the central frame (140).

[0143] The inner frame (140) has two inner frame vertical slits (141) on its cylindrical outer surface, positioned opposite to each other across the center of the circumference.

[0144] The central cylinder fixing projection (142) is a substantially hemispherical projection formed on the inner circumferential surface of the cylindrical central frame (140) near the upper end. The central frame (140) has two central cylinder fixing projections (142) on its cylindrical inner circumferential surface, positioned opposite each other across the center of the circumference.

[0145] The screw member positioning intermediate frame fitting portion (143) is a circumferentially extending slit formed in the portion of the peripheral wall of the cylindrical intermediate frame (140) near the lower end. The intermediate frame (140) has two screw member positioning intermediate frame fitting portions (143) in its cylindrical peripheral wall, positioned opposite each other across the center of the circumference.

[0146] The inner frame claw portion (144) for preventing the inner cylinder from rotating has a projection that protrudes inward from the inner frame near the tip of a U-shaped notch (the vertical line of the U-shape) formed on the circumferential wall of the cylindrical inner frame (140) near the axial middle. In this U-shaped notch, the two horizontal lines of the U-shape extend in the circumferential direction of the inner frame (140).

[0147] The inner frame (140) has two inner frame claws (144) for preventing the inner cylinder from rotating, located opposite each other across the center of the circumference on the cylindrical peripheral wall.

[0148] Figure 5 shows the relationship between the inner frame and the inner component in the main body of the dispensing container of Embodiment 1. Figure 5(A) is a perspective view of the inner frame and the inner component, and Figure 5(B) is a cross-sectional view taken along line AA of Figure 5(A).

[0149] Referring to Figure 5, it can be understood that the internal component (110) is fitted into the vertical slit (141) of the internal frame (140) by the internal component (110) having a protrusion (122) for preventing internal component rotation, thereby fitting the internal component (110) into the internal frame (140) in a manner that prevents relative rotation and allows for vertical movement. Note that the vertical movement range of the internal component (110) within the internal frame (140) is the range in which the internal component (110) has a protrusion (122) for preventing internal component rotation can move within the sum of the range of the thin-walled portion (141a) and the through portion (141b) of the vertical slit of the internal frame.

[0150] Figure 6 shows the screw member in the body of the dispensing container of Embodiment 1. Figure 6(A) is a perspective view of the screw member, Figure 6(B) is a top view, Figure 6(C) is a bottom view, and Figure 6(D) is a front view.

[0151] The screw member (150) shown in Figure 6 has a substantially disc-shaped screw member positioning screw member fitting portion (153), a rod-shaped screw shaft (152) protruding upward from the center of the screw member positioning screw member fitting portion (153), a screw member screw track (151) formed on the screw shaft (152), and a screw member fixing screw member engagement portion (154) formed on the bottom surface of the screw member positioning screw member fitting portion (153).

[0152] The screw member positioning screw member fitting portion (153) is approximately disc-shaped. The thickness of this disc is slightly smaller than the width of the slit in the screw member positioning middle frame fitting portion (143) of the middle frame (140). Also, the diameter of the disc of the screw member positioning screw member fitting portion (153) is slightly larger than the inner diameter of the middle frame (140) forming portion for screw member positioning middle frame fitting portion (143). This size configuration allows the screw member positioning screw member fitting portion (153) to be inserted into the screw member positioning middle frame fitting portion (143) and rotate smoothly.

[0153] In the body of the dispensing container of Embodiment 1, the middle frame (140) is mounted to the screw member (150) in such a way that it can rotate relative to it but cannot move up or down.

[0154] In the body of the dispensing container of Embodiment 1, the screw thread raceway (151) is a male thread and is formed on the screw shaft (152). The diameter of the screw shaft (152) is relatively large, about 50% of the diameter of the screw thread fitting portion (153) for setting the screw thread position. This is because the screw thread raceway (151) formed on the screw shaft (152) forms an effective screw connection with the internal screw raceway (131) of the internal tool (110), thereby enabling smooth raising and lowering of the internal tool (110) and the like.

[0155] In the screw member (150) shown in Figure 6, the screw raceway (151) of the screw member is formed only on the upper portion of the total length of the screw shaft (152). This configuration is also preferable insofar as it allows for effective threading between the screw member raceway (151) and the internal screw raceway (131).

[0156] The screw member fixing screw member engaging portion (154) is a key-shaped projection formed on the bottom surface of the screw member positioning screw member fitting portion (153). The screw member (150) has two screw member fixing screw member engaging portions (154) on the bottom surface of the screw member positioning screw member fitting portion (153), at positions opposite to each other through the center of the bottom surface.

[0157] Figure 7 shows the base of the dispensing container body of Embodiment 1. Figure 7(A) is a perspective view of the base, and Figure 7(B) is a cross-sectional view taken along line AA in Figure 7(A).

[0158] The base (160) in Figure 7 is a roughly cylindrical shape with a bottom. Two screw member fixing base engagement portions (161) are formed on the bottom surface of the base (160) at positions that can engage with each of the two screw member position setting screw member fitting portions (153) of the screw member (150).

[0159] Figure 8 shows the state in which the screw member (150) is fixedly attached to the hakama (160). Figure 8(A) is a perspective view of the hakama and screw member, and Figure 8(B) is a cross-sectional view taken along line AA of Figure 8(A). The cross-sectional view in Figure 8(B) shows how the hakama engaging portion (161) for fixing the screw member of the hakama (160) and the screw member fitting portion (153) for setting the screw member position of the screw member of the screw member (150) are engaged.

[0160] Figure 9 shows the body of the dispensing container of Embodiment 1, with the skirt, screw member and inner part assembled. Figure 9(A) is a perspective view of the skirt (160), screw member (150), and inner part (110) of the body of the dispensing container of Embodiment 1, and Figure 9(B) is a cross-sectional view taken along line AA of Figure 9(A).

[0161] Furthermore, Figure 9(C) is a cross-sectional view showing the state in which the base (160) and screw member (150) and the central tool (110) are rotated relative to each other from the state in Figure 9(B), thereby slightly raising the central tool (110). When the base (160) and screw member (150) and the central tool (110) are rotated relative to each other, the screw thread track (151) of the screw member (150) slides along the central tool screw track (131) of the central tool (110), causing the central tool (110) to rise relative to the base (160) and screw member (150).

[0162] The dispensing container of Embodiment 1 has an outer cylinder. The outer cylinder is shown in Figure 10. Figure 10(A) is a perspective view of the outer cylinder, and Figure 10(B) is a cross-sectional view taken along line AA in Figure 10(A).

[0163] The outer cylinder (180) in Figure 10 is roughly cylindrical in shape. Looking at the cross-sectional view in Figure 10(B), an outer cylinder projection (181) can be seen near the lower end of the outer cylinder (180) that protrudes radially inward. This is a part that, when the inner frame (140) is inserted into the outer cylinder (180), engages with the inner frame step (145) that the inner frame (140) has near its axial center, thereby increasing the unity between the outer cylinder (180) and the inner frame (140) and facilitating the relative rotation between the skirt (160) and the inner frame (140). However, this projection is not essential to the outer cylinder of the dispensing container of the present invention.

[0164] Figure 11 shows an overall view of the main body of the dispensing container of Embodiment 1. Figure 11(A) is a perspective view of the main body, Figure 11(B) is a cross-sectional view along line AA of Figure 11(A), and Figure 11(C) is a cross-sectional view along line BB of Figure 11(A).

[0165] In the perspective view of Figure 11(A), essentially only the skirt (160) and outer cylinder (180) are visible. However, referring to the cross-sectional views of Figures 11(B) and 11(C), the following can be understood. The screw member (150) is fixedly attached to the skirt (160) via the screw member fixing screw member engaging portion (154) and the screw member fixing skirt engaging portion (161). The screw member position setting screw member fitting portion (153) is fitted into the screw member position setting middle frame fitting portion (143), so that the middle frame (140) is fitted into the skirt (160) via the screw member (150) so that it can rotate relative to the frame but cannot move up or down. The protrusion (122) for preventing rotation of the inner component is fitted into the vertical slit (141) of the inner frame, so that the inner component (110) is fitted into the inner frame (140) in a way that prevents relative rotation and allows for vertical movement. The threaded thread raceway (151) of the threaded member (150) and the threaded thread raceway (131) of the internal part (110) are screwed together, and The inner frame (140) is fixedly inserted into the outer cylinder (180).

[0166] With the above configuration, in the main body of the dispensing container of Embodiment 1, by rotating the skirt (160) and the outer cylinder (180) relative to each other, the inner screw track (131) of the inner component (110) slides on the screw member screw track (151) of the screw member (150), thereby allowing the inner component (110) to be raised and lowered relative to the inner frame (140), screw member (150), skirt (160), and outer cylinder (180).

[0167] <Refill> Figure 12 shows the refill tray of the dispensing container of Embodiment 1. Figure 12(A) is a perspective view of the refill tray, Figure 12(B) is a top view of the refill tray, Figure 12(C) is a bottom view of the refill tray, Figure 12(D) is a cross-sectional view of Figure 12(A) along line AA, and Figure 12(E) is a cross-sectional view of Figure 12(A) along line BB.

[0168] The inner tray (210) in Figure 12 has a roughly cylindrical shape and includes a contents storage section (211), an inner tray divider section (214), a protrusion for fixing the contents (212), and an inner tray engagement section (213) for preventing the inner tray from rotating.

[0169] The inner tray (210) has an inner tray divider (214) that divides the cylindrical internal space into upper and lower sections, and the space above the inner tray divider (214) of the inner tray (210) is the contents storage section (211). The inner tray divider (214) also has two radially opposite air vents (214a) for filling the contents.

[0170] The inner tray (210) may have a protrusion for securing contents that extends from the inner surface of its peripheral wall into the contents storage section (211), but this is not shown in Figure 12.

[0171] The internal component fixing projection (212) is a substantially rectangular projection that protrudes inward from the inner surface of the portion of the peripheral wall of the internal tray (210) near the lower end. The internal tray (210) has two internal component fixing projections (212) in the portion of the peripheral wall near the lower end, at positions opposite to each other across the center of the circumference.

[0172] Furthermore, the intermediate plate engagement portion (213) for preventing the intermediate plate from rotating is a semi-circular projection that protrudes outward from the outer circumferential surface of the peripheral wall of the intermediate plate (210) near the lower end. On both sides of this intermediate plate engagement portion (213) for preventing the intermediate plate from rotating, notches are formed that extend upward from the lower end of the peripheral wall of the intermediate plate (210), and flexibility is provided to the region in which the intermediate plate engagement portion (213) for preventing the intermediate plate from rotating is formed.

[0173] The inner plate (210) has two inner plate anti-rotation engaging parts (213) located at positions opposite to each other across the center of the circumference, near the lower end of the peripheral wall.

[0174] Figure 13 shows the contents (300) of the inner tray (210) with lipstick stored in the contents storage section (211). Figure 13(A) is a perspective view, and Figure 13(B) is a cross-sectional view taken along line AA of Figure 13(A).

[0175] Figure 14 shows the inner cylinder of the refill for the retractable container of Embodiment 1. Figure 14(A) is a perspective view of the inner cylinder, Figure 14(B) is a top view of the inner cylinder, Figure 14(C) is a bottom view of the inner cylinder, and Figure 14(D) is a front view of the inner cylinder.

[0176] The inner cylinder (220) in Figure 14 has a roughly cylindrical shape and includes an L-shaped slit (221) for fixing the inner frame, an inner cylinder engagement part (222) for preventing the inner plate from rotating, and an inner cylinder engagement part (223) for preventing the inner cylinder from rotating.

[0177] The inner cylinder (220) has a roughly cylindrical shape, but its upper end is cut at an angle.

[0178] The L-shaped slit (221) for fixing the inner frame is an L-shaped slit consisting of a straight vertical cut portion (221a) extending upward from the lower end of the inner cylinder, and a straight horizontal cut portion (221b) extending circumferentially from the upper end of the vertical cut portion (221a). In the L-shaped slit (221) for fixing the inner frame, the length of the horizontal cut portion (221b) is shorter than that of the vertical cut portion (221a).

[0179] The inner cylinder (220) has two L-shaped slits (221) for fixing the inner frame (140) of the main body, at positions corresponding to each of the protrusions (142) for fixing the inner cylinder that the inner frame (140) of the main body has.

[0180] The inner cylinder engagement portion (222) for preventing the inner tray from rotating is a roughly rectangular hole formed near the lower end of the inner cylinder (220). The inner cylinder (220) has two inner cylinder engagement portions (222) for preventing the inner tray from rotating, each of which is located at a position corresponding to the inner tray engagement portion (213) of the inner tray (210).

[0181] The internal cylinder rotation prevention internal cylinder engagement portion (223) is a vertically elongated, roughly rectangular hole formed slightly above the lower end of the internal cylinder (220). The internal cylinder (220) has two internal cylinder rotation prevention internal cylinder engagement portions (223) at positions corresponding to each of the internal frame claw portions (144) for preventing internal cylinder rotation that are present on the internal frame (140) of the main body.

[0182] In the refill for the dispensing container of Embodiment 1, the inner tray is fitted into the inner cylinder so as to be unable to rotate relative to it and so as to be able to move up and down. Figure 15 shows the inner tray fitted into the inner cylinder. Figure 15(A) is a perspective view of the inner tray and inner cylinder, and Figure 15(B) is a cross-sectional view taken along line AA of Figure 15(A). Figure 15(C) is a cross-sectional view showing the inner tray slightly raised from the state shown in Figure 15(B).

[0183] In the state shown in Figures 15(A) and 15(B), where the inner plate (210) is at its lowest point in the inner cylinder (220), the inner plate rotation prevention engaging portion (213) of the inner plate (210) engages with the inner cylinder rotation prevention engaging portion (222) of the inner cylinder (220), thereby suppressing the relative rotation between the inner plate (210) and the inner cylinder (220). However, as shown in Figure 15(C), the flexibility of the region where the inner plate rotation prevention engaging portion (213) is formed releases the engagement between the inner plate rotation prevention engaging portion (213) and the inner cylinder rotation prevention engaging portion (222), allowing the inner plate (210) to be raised relative to the inner cylinder (220).

[0184] <Installing the refill into the main unit> In the retractable container of Embodiment 1, the refill can be attached to the main body by inserting it into the main body and rotating the main body and the refill slightly relative to each other. Furthermore, with the refill attached to the main body, the refill can be pulled out of the main body by rotating the main body and the refill slightly relative to each other.

[0185] Figure 16 shows the state in which a refill is being inserted into the body of the retractable container of Embodiment 1. Figure 16(A) is a perspective view showing only the inner frame of the body and the inner cylinder of the refill in the state in which the refill is being inserted into the body, and Figure 16(B) is a cross-sectional view of line AA in Figure 16(A).

[0186] In the state shown in Figure 16, the central frame (140) of the main body has a protruding part (142) for fixing the inner cylinder, which is fitted into the vertical notch (221a) of the L-shaped slit (221) for fixing the central frame of the refill's inner cylinder (220). While inserting the refill into the main body, the central frame (140) of the main body has a protruding part (142) for fixing the inner cylinder, which slides from bottom to top within the vertical notch (221a) of the L-shaped slit (221) for fixing the central frame of the refill's inner cylinder (220).

[0187] Figures 17 and 18 show the state of the retractable container just before the refill is inserted into the main body and assembled. Figure 17(A) is a perspective view showing only the inner frame of the main body and the inner cylinder of the refill, and Figure 17(B) is a cross-sectional view of Figure 17(A) along line AA. Figure 18(A) is a perspective view showing only the inner components of the main body and the inner tray of the refill, and Figure 18(B) is a cross-sectional view of Figure 18(A) along line AA.

[0188] Just before assembling the main body and the refill, as shown in Figure 17, the projection (142) for fixing the inner cylinder of the main body's inner frame (140) reaches the uppermost part of the vertical cut (221a) of the L-shaped slit (221) for fixing the inner frame of the refill's inner cylinder (220). Also, as shown in Figure 18, the projection (212) for fixing the inner component of the refill's inner tray (210) reaches a height that allows it to engage with the key-shaped projection (121) for fixing the inner tray of the main body's inner component (110).

[0189] Figures 19 and 20 show the assembled state after slightly rotating the main body and refill relative to each other from the state shown in Figures 17 and 18. Figure 19(A) is a perspective view showing only the inner frame of the main body and the inner cylinder of the refill, Figure 19(B) is a cross-sectional view of Figure 19(A) along line AA, and Figure 19(C) is a cross-sectional view of Figure 19(A) along line BB. Also, Figure 20(A) is a perspective view showing only the inner components of the main body and the inner tray of the refill, and Figure 20(B) is a cross-sectional view of Figure 20(A) along line AA.

[0190] When the refill is assembled to the main body, as shown in Figure 19, the central frame (140) of the main body has a protruding part (142) for fixing the central cylinder, which fits into the horizontal notch (221b) of the L-shaped slit (221) for fixing the central frame of the refill's central cylinder (220), and engages with it. Furthermore, the central frame claw (144) for preventing the central cylinder from rotating of the central frame (140) engages with the central cylinder engagement part (223) for preventing the central cylinder from rotating of the refill's central cylinder (220).

[0191] Furthermore, as shown in Figure 20, the refill tray (210) has a protruding part (212) for securing the inner container, which fits into the key-shaped portion of the key-shaped protruding part (121) for securing the inner container (110) of the main body and engages with it.

[0192] In the retractable container of Embodiment 1, when the refill is assembled into the main body, as described above, The engagement between the protrusion (142) for fixing the inner cylinder of the main body's inner frame (140) and the L-shaped slit (221) for fixing the inner frame of the refill's inner cylinder (220), The engagement between the inner frame claw portion (144) for preventing the inner cylinder from rotating on the inner frame (140) of the main body and the inner cylinder engagement portion (223) for preventing the inner cylinder from rotating on the inner cylinder (220) of the refill, and The engagement between the key-shaped projection (121) for securing the inner tray of the main body (110) and the projection (212) for securing the inner tray of the refill (210). These things happen simultaneously.

[0193] <Feedback mechanism> Figure 21 shows the process of dispensing the contents after the refill has been assembled into the body of the dispensing container of Embodiment 1. Figure 21(A) is a cross-sectional view showing the state of the body, refill, and contents before dispensing. Figure 21(B) is a cross-sectional view showing the state during dispensing.

[0194] In the state shown in Figure 21(A), a screw member (150) is fixedly attached to the base (160) of the main body. Furthermore, a refill cylinder (220) is fixedly assembled to the inner frame (140), and an outer cylinder (180) is attached to permanently cover the inner frame (140). An inner component (110) is further fitted into the inner frame (140) in a manner that prevents relative rotation and allows for vertical movement.

[0195] Here, relative rotation is possible between the inner frame (140) and the screw member (150), but relative vertical movement is not possible. Therefore, a relationship exists between the inner frame (140) and the outer cylinder (180) and the skirt (160) where relative rotation is possible, but relative vertical movement is not.

[0196] On the other hand, the main body's inner container (110) has a refill tray (210) fixedly attached to it, and the tray (210) contains a rod-shaped contents (300).

[0197] Therefore, in the state shown in Figure 21(A), when the base (160) and outer cylinder (180) of the main body are rotated relative to each other, the set of base (160) and screw member (150) and the set of outer cylinder (180), inner frame (140), inner tool (110), and inner plate (210) rotate relative to each other. As a result, the inner tool screw track (131) of the inner tool (110) slides along the screw member screw track (151) of the screw member (150).

[0198] As a result, the inner container (110) and the inner tray (210) move up and down relative to the base (160), screw member (150), inner frame (140), outer cylinder (180), and inner cylinder (220). This causes the contents (300) contained in the inner tray (210) to move up and down as well. Therefore, by rotating the base (160) and the outer cylinder (180) relative to each other, the tip of the contents (300) protruding above the inner tray (210) is extended to the top of the inner cylinder (220) and retracted downwards.

[0199] Embodiment 2 Figures 22 to 35 show diagrams illustrating the form of the retractable container of Embodiment 2. Of these, Figures 22 to 29 relate to the main body, Figures 30 to 32 relate to the refill, Figures 33 and 34 relate to the assembly of the refill into the main body, and Figure 35 relates to the entire retractable container of Embodiment 2.

[0200] <Main body> Figures 22 and 23 show the internal components of the dispensing container body of Embodiment 2. Figure 22(A) is a perspective view of the internal components, Figure 22(B) is a cross-sectional view along line AA of Figure 22(A), and Figure 22(C) is a cross-sectional view along line BB of Figure 22(A). Figure 23(A) is a top view of the internal components, Figure 23(B) is a bottom view, Figure 23(C) is a front view, and Figure 23(D) is a right side view.

[0201] The inner component (610) shown in Figures 22 and 23 has a roughly cylindrical shape and includes a key-shaped projection (621) for fixing the inner tray and an inner component projection (632).

[0202] The key-shaped projection (621) for fixing the inner tray in the inner part (610) is an inverted L-shaped projection that protrudes upward from the circumference of the upper end of the inner part (610). The inner part (610) has two key-shaped projections (621) for fixing the inner tray at the upper end of its cylindrical shape, at positions opposite to each other across the center of the circumference.

[0203] The internal component projection (632) of the internal component (610) is a substantially rectangular projection formed near the lower end of the cylindrical shape. The internal component projection (632) slides along the screw thread track of the screw member, causing the internal component (and the internal plate fixed relative to the internal component) to move up and down relative to the screw member (and the internal frame and base fixed relative to it). It is also fitted into the vertical slit of the internal frame, and has the function of fitting the internal component into the internal frame in a way that prevents relative rotation and allows for vertical movement.

[0204] The central part (610) has a central part projection (632) which is formed as a rectangular projection with a slightly angled cross-section. The angled cross-section is to facilitate the sliding of the screw member on the screw thread track.

[0205] The inner component (610) has two inner component protrusions (632) located near the lower end of the outer surface of its cylindrical shape, at positions opposite to each other across the center of the circumference.

[0206] In the internal component (610) shown in Figures 22 and 23, there are further two vertical slits in the internal component, each of the two internal component protrusions (632) at a position where the central angle of the circumference is 90°.

[0207] Figure 24 shows the inner frame of the dispensing container body of Embodiment 2. Figure 24(A) is a perspective view of the inner frame, Figure 24(B) is a cross-sectional view of Figure 24(A) along line AA, and Figure 24(C) is a cross-sectional view along line BB.

[0208] The middle frame (640) shown in Figure 24 is the same as the middle frame (140) of Embodiment 1 in the following respects. It has a roughly cylindrical shape. The upper part is formed to be slightly thicker than the lower part, and there is a step (645) in the middle frame near the center in the axial direction. The frame has vertical slits (641), protrusions (642) for fixing the inner cylinder, and claws (644) for preventing the inner cylinder from rotating.

[0209] However, it differs from the central frame (140) of Embodiment 1 in the following respects. Instead of a central frame fitting portion for setting the position of the screw member, it has an engaging portion (643) for fixing the hook. The vertical slit (641) of the central frame consists only of a notched through portion extending upward from the lower end of the central frame (640), and does not have a thin-walled portion. The length of the vertical slit (641) of the middle frame is approximately 60% of the length of the middle frame (640), and The formation positions of each part are different.

[0210] The hook-fastening engagement portion (643) is a circumferentially extending slit formed in the portion of the peripheral wall of the cylindrical middle frame (140) near the lower end. The middle frame (640) has two hook-fastening engagement portions (643) at opposing positions with respect to the center of the circumference near the lower end of the cylinder.

[0211] The middle frame (640) shown in Figure 24 has a hook-fixing engagement part (643) that replaces the middle frame fitting part for setting the position of the screw member, which engages with the hook's middle frame fixing engagement part, thereby holding the middle component (610) in the space formed by the middle frame and the hook in a position where it cannot rotate relative to the other and can move up and down, except that it exhibits substantially the same function as the middle frame (140) of Embodiment 1.

[0212] Figure 25 shows a perspective view of the hook.

[0213] The hook (670) in Figure 25 has a disc-shaped hook base plate (671) and a key-shaped projection (672) for fixing the middle frame that protrudes upward from the hook base plate (671). The hook (670) has two middle frame fixing engagement parts (672) at positions corresponding to each of the hook fixing engagement parts (643) of the middle frame (640).

[0214] Figure 26 shows the body of the dispensing container of Embodiment 2, in which the inner container is held in the space formed by the inner frame and the hook. Figure 26(A) is a perspective view of the inner container, inner frame, and hook, Figure 26(B) is a cross-sectional view along line AA of Figure 27(A), and Figure 26(C) is a cross-sectional view along line BB of Figure 26(A).

[0215] As shown in Figure 26, the hook-fixing engagement portion (643) of the middle frame (640) and the middle frame-fixing engagement portion (672) of the hook (670) engage with each other, and the internal component (610) is housed and held in the space formed by the middle frame (640) and the hook base plate (671) of the hook (670). At this time, since the internal component protrusion (632) of the internal component (610) is fitted into the middle frame vertical slit (641) of the middle frame (640), the internal component (610) is unable to rotate relative to the middle frame (640) and the hook (670), and is able to move up and down.

[0216] As shown in Figure 27(B), the internal component projection (632) of the internal component (610), which is fitted into the vertical slit (641) of the internal frame (640), extends further outward, penetrating the vertical slit (641) of the internal frame (640). This extended portion of the internal component projection (632) is intended to slide along the screw thread track of the screw member.

[0217] Figure 27 shows the base of the dispensing container body of Embodiment 2. Figure 27(A) is a perspective view of the base, Figure 27(B) is a top view, Figure 27(C) is a bottom view, and Figure 27(D) is a cross-sectional view taken along line AA in Figure 27(A).

[0218] The skirt (660) in Figure 27 is a cylindrical shape with a bottom, does not have a skirt engagement portion for fixing a screw member on the inside of the bottom surface, and is substantially the same as the skirt (160) of Embodiment 1, except that the ratio of diameter to height is different.

[0219] Figure 28 shows the screw member in the body of the dispensing container of Embodiment 2. Figure 28(A) is a perspective view of the screw member, Figure 28(B) is a top view, Figure 28(C) is a bottom view, and Figure 28(D) is a cross-sectional view taken along line AA in Figure 28(A).

[0220] The screw member (650) shown in Figure 28 has a substantially cylindrical shape and has a screw member screw raceway (651) on its inner circumferential surface. Therefore, the screw member screw raceway (651) of the screw member (650) is an internal thread.

[0221] In Figure 28, the screw thread raceway (651) of the screw member (650) is formed only in a range of approximately 70% of the total axial length from the lower end of the screw member (650). This configuration is also preferable insofar as the central part projection (632) of the central part (610) can slide along the screw thread raceway (651).

[0222] Figure 29 shows an overall view of the main body of the dispensing container of Embodiment 2. Figure 29(A) is a perspective view of the main body, Figure 29(B) is a cross-sectional view along line AA of Figure 29(A), and Figure 29(C) is a cross-sectional view along line BB of Figure 11(A).

[0223] In the perspective view of Figure 29(A), essentially only the upper part of the middle frame (640), the upper part of the screw member (650), and the skirt (660) are visible. However, referring to the cross-sectional views in Figures 29(B) and 29(C), the following can be understood.

[0224] The screw member (650) is fixedly attached to the hakama (660). The central frame (640) and the hook (670) are fixed together as a set and are mounted inside the hakama (660) so as to be rotatable and not so as to be raised or lowered. The inner member (610) is held within a space formed by the middle frame (640) and the hook (670), and the inner protrusion (632) of the inner member (610) is fitted into the vertical slit (641) of the middle frame (640), further penetrates the vertical slit (641) of the middle frame to reach the screw thread track (651) of the screw member (650), and is configured to be slidable on the screw thread track (651) of the screw member.

[0225] With the above configuration, in the main body of the dispensing container according to Embodiment 2, when the skirt (660) and the middle frame (640) are rotated relatively, the inner protrusion (632) of the inner member (610) slides on the screw thread track (651) of the screw member (650), so that the inner member (610) can be moved up and down relative to the middle frame (640), the screw member (650), and the hook (670).

[0226] <Refill> FIG. 30 shows an inner plate in the refill of the dispensing container according to Embodiment 2. FIG. 30(A) is a perspective view of the inner plate, FIG. 30(B) is a top view of the inner plate, FIG. 30(C) is a bottom view of the inner plate, FIG. 30(D) is a front view, and FIG. 12(E) is a cross-sectional view taken along line A-A of FIG. 12(A).

[0227] The inner plate (710) shown in FIG. 30 has a substantially cylindrical shape, and includes a content storage portion (711), an inner member fixing protrusion (712), and an inner plate engagement portion for preventing inner plate rotation (713).

[0228] The inner plate (710) has the same configuration and functions as the inner plate (210) in the refill of Embodiment 1, except that it does not include an inner plate partition step and an air vent hole for content filling formed therein.

[0229] FIG. 31 shows an inner cylinder in the refill of the dispensing container according to Embodiment 2. FIG. 31(A) is a perspective view of the inner cylinder, FIG. 31(B) is a top view of the inner cylinder, FIG. 31(C) is a bottom view, FIG. 31(D) is a front view, and FIG. 31(E) is a right side view.

[0230] The inner cylinder (720) in Figure 31 has a roughly cylindrical shape with its upper end cut at an angle, and includes an L-shaped slit (721) for fixing the inner frame and an inner cylinder engagement part (722) for preventing the inner tray from rotating.

[0231] The L-shaped slit (721) for fixing the inner frame is an L-shaped slit, similar to the L-shaped slit (221) for fixing the inner frame of the inner cylinder (220) in Embodiment 1, consisting of a straight vertical cut portion (721a) extending upward from the lower end of the inner cylinder, and a straight horizontal cut portion (721b) extending circumferentially from the upper end of the vertical cut portion (721a). The inner cylinder (720) has two L-shaped slits (721) for fixing the inner frame, each at a position corresponding to the inner cylinder fixing protrusion (642) of the inner frame (640) of the main body.

[0232] The inner cylinder (720) does not have an inner cylinder engagement portion for preventing the inner cylinder from rotating, and the vertical notch (721a) of the L-shaped slit (721) for fixing the inner frame also functions as an inner cylinder engagement portion for preventing the inner cylinder from rotating. Therefore, the inner cylinder (720) has the same number of L-shaped slits (721) for fixing the inner frame as the inner frame claw portions (644) of the main body's inner frame (640) for preventing the inner cylinder from rotating, and these slits are formed in positions that can engage with each of the inner frame claw portions (644) for preventing the inner cylinder from rotating.

[0233] The inner cylinder engagement portion (722) for preventing the inner tray from rotating is a substantially rectangular hole formed in a plate-shaped projection that protrudes further downward from the lower end of the inner cylinder (720). Its function is the same as that of the inner cylinder engagement portion (222) for preventing the inner tray from rotating in the inner cylinder (220) of Embodiment 1.

[0234] In the refill for the dispensing container of Embodiment 2, the inner tray is fitted into the inner cylinder so as to be unable to rotate relative to it and so as to be able to move up and down. Figure 32 shows the inner tray fitted into the inner cylinder. Figure 32(A) is a perspective view of the inner tray and inner cylinder, and Figure 32(B) is a front view.

[0235] As shown in Figure 32, the intermediate plate engagement portion (713) for preventing rotation of the intermediate plate (710) engages with the intermediate cylinder engagement portion (722) for preventing rotation of the intermediate plate (720), thereby suppressing the relative rotation of the intermediate plate (710) and the intermediate cylinder (720). However, due to the flexibility of the region where the intermediate plate engagement portion (713) is formed, the engagement between the intermediate plate engagement portion (713) and the intermediate cylinder engagement portion (722) can be easily released, and the intermediate plate (710) can be raised relative to the intermediate cylinder (720).

[0236] <Installing the refill into the main unit> Similar to the retractable container of Embodiment 1, the refill in Embodiment 2 can be attached to the main body by inserting the refill into the main body and rotating the main body and refill slightly relative to each other. Furthermore, with the refill attached to the main body, the refill can be pulled out of the main body by rotating the main body and refill slightly relative to each other.

[0237] Figure 33 shows the relationship between the inner frame of the main body and the inner cylinder of the refill when the refill is assembled into the main body, and Figure 34 shows the relationship between the inner component of the main body and the inner tray of the refill. Figure 33(A) is a perspective view of the inner frame and inner cylinder when the refill is assembled into the main body, and Figure 33(B) is a cross-sectional view of Figure 33(A) along line AA. Figure 34(A) is a perspective view of the inner component and inner tray, and Figure 34(B) is a cross-sectional view of Figure 34(A) along line AA.

[0238] When the refill is assembled into the main body, as shown in Figure 33, the inner tube fixing projection (642) of the main body's inner frame (640) engages with the horizontal notch (721b) of the L-shaped slit (721) for fixing the inner frame of the refill's inner tube (720). Furthermore, the inner frame claw (644) for preventing the inner tube from rotating of the inner frame (640) engages with the vertical notch (721a) of the L-shaped slit (721) for fixing the inner frame of the inner tube (720). Also, as shown in Figure 34, the inner component fixing projection (712) of the refill's inner tray (710) engages with the key-shaped portion of the inner tray fixing projection (621) of the main body's inner component (610).

[0239] In the retractable container of Embodiment 2, when the refill is assembled into the main body, as described above, The engagement between the protrusion (642) for fixing the inner cylinder of the main body's inner frame (640) and the L-shaped slit (721) for fixing the inner frame of the refill's inner cylinder (720), The engagement between the inner frame claw portion (644) of the main body's inner frame (640) for preventing the inner cylinder from rotating and the L-shaped slit (721) for fixing the inner frame of the refill's inner cylinder (720), and The engagement between the key-shaped projection (621) for securing the inner tray of the main body (610) and the projection (712) for securing the inner tray of the refill (710). These things happen simultaneously.

[0240] <Overall view of the retractable container> Figure 35 shows the entire retractable container (body and refill) of Embodiment 2. Figure 35(A) is a perspective view of the retractable container, Figure 35(B) is a cross-sectional view of Figure 35(A) along line AA, and Figure 35(C) is a cross-sectional view of Figure 35(A) along line BB.

[0241] In the main body of the lifting container shown in Figure 35, as explained above with reference to Figure 29, by rotating the skirt (660) and the middle frame (640) relative to each other, the protrusion (632) of the middle component (610) slides on the screw thread track (651) of the screw member (650), thereby allowing the middle component (610) to be raised and lowered relative to the middle frame (640), the screw member (650), and the hook (670).

[0242] Furthermore, the main body's inner container (610) and the refill tray (710) are different. Engagement between the key-shaped projection (621) for fixing the inner tray and the projection (712) for fixing the inner component. Therefore, it is fixedly attached (see Figure 35(B)), and, The main body frame (640) and the refill cylinder (720) are, The engagement between the protrusion (642) for fixing the inner cylinder and the L-shaped slit (721) for fixing the inner frame, and Engagement between the inner frame claw portion (644) for preventing rotation of the inner cylinder and the L-shaped slit (721) for fixing the inner frame. is fixedly attached thereby (see Figures 33 and 34).

[0243] With the above configuration, in the dispensing container according to Embodiment 2, by rotating the holder (660) and the middle frame (640) relative to each other, the inner member (610) and the inner tray (710) move up and down relatively with respect to the holder (660), the screw member (650), the middle frame (640), and the inner cylinder (720). Accordingly, the content stored in the inner tray (710) also moves up and down. Therefore, by rotating the holder (660) and the middle frame (640) relative to each other, the leading end of the content is dispensed to the upper part of the inner cylinder (720) and retracted downward.
