Description

[Technical field]

[0001] The present invention relates to a squeeze dispenser. [Background technology]

[0002] A squeeze dispensing container is known which comprises a squeezable container body, a cap member attached to the neck of the container body, and a dispensing body provided with a nozzle head attached to the cap member, and dispensing the content liquid as foam from the nozzle head. In this squeeze container, the flow path of the content liquid in the dispensing body leads to a foam generating member, and by squeezing the container body, the content liquid is mixed with air in the flow path, and the mixture is passed through the foam generating member to foam the content liquid.

[0003] As a squeeze discharge container, one has been proposed in which a discharge flow path for discharging the content liquid can be opened and closed by rotating a nozzle head portion. For example, Patent Document 1 discloses a foam-spouting container which comprises an attachment cap having a flow port for discharging the liquid contents, a nozzle head which has an opening / closing lid and a nozzle and which can rotate between a closed position and an open position in which the opening / closing lid opens and closes the flow port, and a partition member which has an air inlet hole and a liquid inlet hole which connect the storage space for the liquid contents to a mixing chamber, and in which an air passage hole in the attachment cap which does not communicate with the flow port is blocked by the nozzle head in the closed position and is opened in the open position, connecting the storage space with the outside.

[0004] Patent document 2 discloses a foam-ejecting container which is equipped with a check valve having a sealing membrane portion which abuts against the inner surface of the mounting cap to block the return flow path when the nozzle head is in the open position, and which moves away from the inner surface when the nozzle head is in the closed position, and the female threaded portion which engages with the male threaded portion of the mounting cap has a bulge portion which bulges out from at least one of the sides of a pair of threads located on either side of the threads of the female threaded portion when in the open position.

[0005] Patent Document 3 discloses a foam-spouting container which comprises an attachment cap, an opening / closing lid portion which releasably closes a flow port inside the cap and a nozzle which communicates with the flow port, a nozzle head which is attached to the attachment cap so as to be movably mounted in the axial direction of the container, and a partition member, wherein an introduction flow path which connects the flow port to the inside of the container body is formed between the inner surface of the attachment cap and the outer surface of the partition member, and a surrounding cylindrical portion whose inner side forms part of the introduction flow path and a check valve which releasably closes the inside of the surrounding cylindrical portion are fixed to the partition member, and when the nozzle head is in the open position, the fitting cylindrical portion of the attachment cap fits tightly into the surrounding cylindrical portion.

[0006] Patent document 4 discloses a foam-spouting container in which the nozzle head is rotatable between a closed position and an open position, and when the nozzle head is in the closed position, an opening / closing lid portion provided on the nozzle head fits into a flow tube portion inside an attachment cap to block the flow port, and when the nozzle head is in the open position, the opening / closing lid portion moves upwards to open the flow port.

[0008] The opening and closing mechanism by rotation of the nozzle head portion described in Patent Documents 1 to 4 is based on rotation relative to a cap member (attached cap) attached to the container body. The cap member described in Patent Documents 1 to 4 is fixed to the neck portion of the container body so as not to be detachable. On the other hand, from the viewpoint of reducing environmental load, it is required that the content liquid can be refilled into the container body. One such form is a form in which the cap member is detachable from the container body, but the squeeze discharge container described in Patent Documents 1 to 4 does not adopt such a form. Furthermore, these Patent Documents do not consider at all the operability when discharging the content liquid when the opening and closing mechanism by rotation of the nozzle head portion is provided and the cap member is detachable from the container body.

[0009] The present invention relates to providing a squeeze dispensing container which is equipped with an opening and closing mechanism that rotates a nozzle head portion, has a cap member that is detachable from a container body, and yet has excellent operability when dispensing the content liquid. [Means for solving the problem]

[0010] The present invention relates to a squeeze dispenser container comprising: a container body with a neck portion and a flexible body portion in which the liquid contents are contained; a cap member that is removably screwed onto the neck portion; and a dispenser body portion provided with a nozzle head portion that is rotatably attached to the cap member and can be switched between an open state in which the liquid contents are dispensed by a rotational operation and a closed state in which the liquid contents are blocked from being dispensed. In one embodiment, the cap member preferably has an inner surface of a cylindrical mounting portion that is screwed onto the neck portion, a female thread ridge that threadably engages with a male thread ridge provided on the outer surface of the neck portion, and a male guide thread ridge that guides the rotational operation of the discharge main body portion is formed on the outer surface of the cylindrical mounting portion, and also has an expanded skirt portion that extends from the edge of the cylindrical mounting portion in an expanded state on the side opposite the top surface portion. In one embodiment, it is preferable that the ejection main body is attached to the cap member with the nozzle head portion positioned outside the cap member by arranging an opening and closing mechanism for the ejection flow path inside the cap member through a top opening formed in the top surface portion of the cap member, and by overlapping and mounting an operating cylindrical portion having a guide female thread ridge on its inner surface that screws into the guide male thread ridge of the mounting cylindrical portion on the outer periphery of the mounting cylindrical portion of the cap member. In one embodiment, the open state and the closed state are switched by gripping and rotating the operating cylindrical portion of the ejection main body, and it is preferable that the cap member and the ejection main body are attached and detached to and from the container body by gripping and rotating the enlarged skirt portion of the cap member. Effect of the Invention

[0011] The squeeze discharge container of the present invention is provided with an opening and closing mechanism that rotates the nozzle head portion, and the cap member is detachable from the container body, yet has excellent operability when discharging the content liquid.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] The present invention will be described below based on preferred embodiments with reference to the drawings. Figures 1 to 9 show one embodiment of the squeeze discharge container of the present invention. The squeeze discharge container 1 of this embodiment (hereinafter, simply referred to as "container 1") includes a container body 10 in which the content liquid is stored, a discharge main body 2 that foams the content liquid and discharges it to the outside, and a cap member 5 that is attached to a neck part 14 of the container body 10. The container 1 of this embodiment has a flexible container body 10, and by pressing the container body 10 with a hand or the like, the content liquid is ejected as foam from the nozzle portion 22 of the nozzle head portion 20 provided on the ejection main body portion 2.

[0014] The liquid contents contained in the container 1 of this embodiment include, for example, cleaning agents such as liquid soap, hand sanitizers that can be made into a foam by adding an activator, hair cosmetics such as hair styling agents, fixatives, and hair growth agents, skin cosmetics such as lotions, milks, and serums, shaving foam, dishwashing detergent, etc.

[0015] In this specification, "upper", "upper side" or "upper side" refers to the direction toward the upper side (upper side) in the vertical direction when the bottom 16 of the container body 10 is placed on a horizontal surface and stands on its own, and "lower", "lower side" or "lower side" refers to the direction toward the lower side (lower side) in the vertical direction when the container body 10 stands on its own. In such a standing state, the height direction Z of the container 1 coincides with the vertical direction. In the present specification, unless otherwise specified, the container 1 is described in a state in which the container 1 is self-supporting.

[0016] The container body 10 of this embodiment has a cylindrical body 11, a top surface 13 that closes the upper opening of the body 11, a bottom surface 16 that closes the lower opening of the body 11, and a neck portion 14 that protrudes upward from the top surface 13. The central axis of the body 11 coincides with the height direction Z of the container 1, and the bottom surface 16 and the top surface 13 are disposed opposite each other in the height direction Z. The container body 10 has an internal storage space S that stores the liquid content (see FIG. 2). The neck portion 14 has a cylindrical shape and has a smaller horizontal cross-sectional area than the body 11. The internal space of the neck portion 14 communicates with the storage space S in the body 11.

[0017] The container body 10 of this embodiment has a flexible bottle shape. The container body 10 is a blow molded product made of synthetic resin, and the body portion 11 can be horizontally pressed (squeezed) to deform. In order to ensure the compression deformability of the body 11, it is preferable that the material from which the container body 10 is formed be a polyolefin resin such as polypropylene (PP), high density polyethylene (HDPE), medium density polyethylene (MDPE), low density polyethylene (LDPE), or a polyester resin such as polyethylene terephthalate (PET), either alone or in combination.

[0018] The body 11 of this embodiment has an elliptical horizontal cross section. In addition, the top surface 13 of the container body 10 also has an elliptical shape in a plan view. The container 1 of this embodiment has a width direction X along the long axis direction of the horizontal cross section (ellipse) of the body 11 (see Figs. 1 to 4), and a depth direction Y along the short axis direction of the horizontal cross section (ellipse) (see Fig. 7). When the container 1 of this embodiment is viewed from the front in the depth direction Y, the body 11 has a contour in which both side edges (ridge lines) in the width direction X are curved (see FIG. 1). This body 11 has a constricted portion 11a in which the central portion in the height direction Z of both side edges is constricted inward in the width direction X, and each of the portions above and below the constricted portion 11a has a shape that protrudes outward in the width direction X beyond the constricted portion 11a. That is, the horizontal cross-sectional area of ​​the body 11 varies in the height direction Z, and the horizontal cross-sectional area is smallest at the constricted portion 11a.

[0019] The neck portion 14 of this embodiment is provided on the top surface 13 of the container body 10. The container body 10 of this embodiment has a pair of step portions 13a on each side of the top surface 13 in the width direction X of the neck portion 14 (see FIG. 7). The step portions 13a are one step higher than the other portions of the top surface 13 other than the step portions 13a, and have a generally crescent shape in a plan view. A male thread ridge 14a is formed on the outer circumferential surface of the neck portion 14 (see Figs. 6 and 7), and a cap member 5 described later is detachably screwed onto the neck portion 14 by screwing into the male thread ridge 14a. In other words, the cap member 5 is detachable from the neck portion 14 of the container body 10. In this embodiment, the male thread ridge 14a and the female thread ridge 54b described later form a single thread. Further, a cylinder portion 3 of the discharge main body 2, which will be described later, is inserted inside the neck portion 14 (see FIG. 2).

[0020] The cap member 5 in this embodiment is a member that is screwed onto the neck portion 14 of the container body 10, and is a member to which the discharge main body 2, which will be described later, is attached. In other words, the discharge main body 2 is attached to the neck portion 14 via the cap member 5. The cap member 5 is a cylindrical body having an internal space that penetrates in the height direction Z, and has a top surface portion 51 (hereinafter also referred to as the "cap top surface portion 51") having an opening 51a at the top, an attachment cylindrical portion 54 that is screwed onto the neck portion 14, and an enlarged skirt portion 55 that extends downward from the edge of the attachment cylindrical portion 54 (see Figure 3). The mounting cylinder portion 54 is located between the cap top surface portion 51 and the enlarged diameter skirt portion 55 in the height direction Z, and the enlarged diameter skirt portion 55 is located below the mounting cylinder portion 54 (see FIG. 4).

[0021] The cap member 5 of this embodiment has an opening tube portion 52 that is located above the mounting cylinder portion 54 and forms an opening 51a (hereinafter also referred to as "top surface opening 51a") in the cap top surface portion 51, and a head mounting tube portion 53 that is arranged concentrically with the opening tube portion 52 (see FIG. 3). The head mounting tube portion 53 protrudes upward from the upper end portion of the mounting cylinder portion 54 via a step. That is, the head mounting tube portion 53 is connected to the upper end portion of the mounting cylinder portion 54. The opening tube portion 52 is located radially inward of the head mounting tube portion 53, and the lower end portion of the opening tube portion 52 is connected to the inner circumferential surface of the head mounting tube portion 53. A groove is formed between the opening tube portion 52 and the head mounting tube portion 53, and the downward tube portion 24 of the nozzle head portion 20 described later is inserted into the groove.

[0022] The mounting cylinder 54 has a female thread ridge 54b formed on its inner circumferential surface (see Figs. 3 and 9), which thread-fits with a male thread ridge 14a provided on the outer circumferential surface of the neck portion 14. The mounting cylinder 54 also has a male guide thread ridge 54a formed on its outer circumferential surface. The male guide thread ridge 54a guides the rotation of the discharge main body 2 (nozzle head 20) mounted on the cap member 5 around the central axis of the container 1.

[0023] The expanded diameter skirt portion 55 in this embodiment is connected to the lower edge of the mounting cylindrical portion 54 via a bulge portion 57, and expands in diameter from the edge toward the opposite side (downward) from the cap top surface portion 51. The bulge portion 57 is a portion that protrudes radially outward from the lower end of the mounting cylindrical portion 54, and the expanded diameter skirt portion 55 extends from the lower edge of the bulge portion 57. Alternatively, the expanded diameter skirt portion 55 may be directly connected to the lower edge of the mounting cylindrical portion 54.

[0024] In this embodiment, the expanding skirt portion 55 has a horizontal cross section that gradually expands downward. The expanding skirt portion 55 has an elliptical horizontal cross section, and the peripheral shape of the lower end edge of the expanding skirt portion 55 is also elliptical, similar to the peripheral shape of the top surface portion 13 of the container body 10. In the container 1 of this embodiment, the cap member 5 is screwed onto the neck portion 14 in a state in which the periphery (outline) of the lower edge of the expanding diameter skirt portion 55 coincides with the periphery (outline) of the top surface portion 13 of the container body 10 in a plan view. That is, the long axis direction of the ellipse formed by the lower edge of the expanding diameter skirt portion 55 coincides with the long axis direction of the ellipse formed by the periphery of the top surface portion 13. In this state, the lower edge of the expanding diameter skirt portion 55 may or may not abut against the top surface portion 13 of the container body 10.

[0025] The cap member 5 of this embodiment has an inner protruding piece 56 extending downward from a part of the periphery of the lower end of the mounting cylindrical part 54 (see Figs. 3 and 9). The inner protruding piece 56 is formed radially inward from the bulging part 57 and the enlarged diameter skirt part 55. When the cap member 5 is screwed onto the neck part 14, the lower end of the inner protruding piece 56 is arranged on the upper surface of the base step part 15 that forms the base of the neck part 14, and is arranged radially outward from the neck part 14 between the mounting cylindrical part 54 and the base step part 15 in the height direction Z. The base of the neck part 14 is the root part of the neck part 14 on the top surface part 13 side. The cap member 5 of this embodiment has a pair of inner protruding pieces 56 at positions opposite to each other in the radial direction. Specifically, the cap member 5 has the pair of inner protruding pieces 56 at positions opposite to each other in the minor axis direction (depth direction Y) of the expanded diameter skirt portion 55, the lower end edge of which is elliptical (see FIG. 8).

[0026] The discharge main body 2 has an internal discharge flow path for discharging the content liquid to the outside of the container 1, and is provided with an opening and closing mechanism for the discharge flow path and a foaming mechanism for the content liquid. The details of the foaming mechanism will be described later. The discharge main body 2 includes a nozzle head 20 and a cylinder 3 that is fixed to the inside of the nozzle head 20 and inserted into the neck portion 14 (see FIG. 2). The nozzle head 20 and the cylinder 3 each form a discharge flow path for the content liquid.

[0027] The nozzle head part 20 of this embodiment has a head part 21, a nozzle part 22 provided on the head part 21, an intermediate cylindrical part 26 hanging down from the lower end of the head part 21, and an operation cylindrical part 27 connected to the lower end of the intermediate cylindrical part 26, and the internal spaces of these parts are communicated. The nozzle head part 20 is attached to the cap member 5 in a state in which it is disposed radially outward of the cap member 5 (see Figs. 1 and 2). Specifically, the guide female thread protrusion 27a formed on the inner peripheral surface of the operation cylindrical part 27 is screwed into the guide male thread protrusion 54a of the mounting cylindrical part 54 of the cap member 5, and the operation cylindrical part 27 is overlapped with the outer peripheral part of the mounting cylindrical part 54, and the nozzle head part 20 is attached to the cap member 5 (see Figs. 3 and 4). That is, when the nozzle head part 20 is attached to the cap member 5, the mounting cylindrical part 54 and the operation cylindrical part 27 overlap in the height direction Z of the container 1.

[0028] The head part 21 of this embodiment forms the top surface part of the nozzle head part 20, and has a dome-shaped head main body 21a and a cylindrical protruding part 21b protruding horizontally from the head main body 21a (see Figs. 3 and 4). The head part 21 has an internal discharge flow path along the horizontal direction from the head main body 21a to the protruding part 21b, and the nozzle part 22 having a discharge port is provided at the tip of the protruding part 21b so as to be angled with respect to the horizontal direction. The nozzle part 22 is provided at the tip of the protruding part 21b with the discharge port facing downward with respect to the horizontal direction. The nozzle part 22 has a foam stabilizing member 23 inside its base end, and the foam stabilizing member 23 blocks the discharge flow path in the nozzle part 22. The foam stabilizing member 23 is a member for making the bubbles of the content liquid foamed by a foaming mechanism described later finer, and the bubbles can be made finer by passing the bubbles through the foam stabilizing member 23 before being discharged from the nozzle part 22. The bubble-stabilizing member 23 may be, for example, a known porous member such as a mesh material.

[0029] The head body 21a of the head part 21 has a downward tube part 24 that hangs down toward the cap member 5. The downward tube part 24 communicates with the inside of the protruding part 21b, and among the peripheral walls forming the tube part 24, the peripheral wall that overlaps with the protruding part 21b in the radial direction hangs down from the radially inner end of the protruding part 21b, and the peripheral wall that does not overlap with the protruding part 21b in the radial direction hangs down from the top surface part of the head body 21a. When the nozzle head part 20 is attached to the cap member 5, the downward tube part 24 hangs down inside the intermediate cylindrical part 26 and is inserted into a groove between the opening tube part 52 and the head mounting tube part 53 in the cap member 5 (see FIG. 4). This seals the flow path between the opening tube part 52 of the cap member 5 and the head body 21a.

[0030] The intermediate cylindrical portion 26 is a cylindrical portion connected to the lower end of the head portion 21, and has an inner diameter larger than the outer diameter of the head mounting cylindrical portion 53 of the cap member 5 (see FIG. 3). When the nozzle head portion 20 is attached to the cap member 5, the intermediate cylindrical portion 26 is disposed radially outward of the head mounting cylindrical portion 53, and the lower end of the intermediate cylindrical portion 26 is disposed on the upper surface of the mounting cylindrical portion 54 (see FIG. 4). The operation cylindrical portion 27 is connected to the lower end of the intermediate cylindrical portion 26. The intermediate cylindrical portion 26 communicates with the internal space of the head portion 21 through the interior of the downward cylindrical portion 24. When the nozzle head portion 20 is attached to the cap member 5, the top surface opening 51a of the cap member 5 is located within the range in which the downward cylindrical portion 24 exists in a plan view.

[0031] The upper opening of the downward cylindrical portion 24 is closed by a plate-shaped opening / closing lid portion 25. The opening / closing lid portion 25 is connected to the upper end portion of the downward cylindrical portion 24. The opening / closing lid portion 25 has a holding through hole 25a formed in the radial center, and an outer through hole 25b formed radially outward from the holding through hole 25a (see FIG. 3). A cylinder body 30, which will be described later, is inserted into the holding through hole 25a. An inner cylindrical portion 25c protruding downward from the periphery of the holding through hole 25a and an outer cylindrical portion 25d protruding downward from the radially inner periphery of the outer through hole 25b are formed on the underside of the opening / closing lid portion 25. When a reduced diameter portion 31 of a cylinder body 30 (described later) is inserted into the holding through hole 25a, the inner cylindrical portion 25c comes into close contact with the outer circumferential surface of the reduced diameter portion 31. In a closed position, which will be described later, the opening / closing lid portion 25 closes the top opening 51a of the cap member 5 (see FIG. 4). In this closed state, the outer cylindrical portion 25d comes into close contact with the inner circumferential surface of the top opening 51a of the cap member 5.

[0032] The operation cylindrical portion 27 is a tubular portion having an inner diameter larger than the outer diameter of the intermediate cylindrical portion 26, and is attached to the outer peripheral surface of the mounting cylindrical portion 54 (see FIG. 4). The operation cylindrical portion 27 is configured to be rotatable around the mounting cylindrical portion 54 by the aforementioned female guide thread ridge 27a and male guide thread ridge 54a being screwed together. In other words, this rotation allows the nozzle head portion 20 to rotate relative to the cap member 5. Furthermore, the nozzle head portion 20 is movable up and down in the axial direction (height direction) of the mounting cylindrical portion 54 by rotating along the female guide thread ridge 27a and male guide thread ridge 54a.

[0033] The discharge main body 2 has an opening / closing mechanism for the discharge flow path of the content liquid disposed inside the cap member 5 via the top opening 51a of the cap member 5. The discharge main body 2 of this embodiment has an opening / closing lid part 25 in the nozzle head part 20 as the opening / closing mechanism. The opening and closing of the discharge flow path by the opening / closing mechanism can be switched by the rotation of the nozzle head part 20. Specifically, when the operating cylinder portion 27 is grasped and the nozzle head portion 20 is rotated and moved upward, it becomes an open state in which the liquid contents are ejected, and when the nozzle head portion 20 is rotated and moved downward from the open state, it becomes a closed state in which the ejection of the liquid contents is blocked.

[0034] In the open state, as the nozzle head 20 moves upward, the opening / closing lid 25 also moves upward, opening the top opening 51a of the cap member 5 and connecting the internal spaces of the opening tube 52 and the downward tube 24. Furthermore, the internal spaces of the head 21 and the downward tube 24 also connect to each other via the outer through-hole 25b of the opening / closing lid 25 (see FIG. 5). This opens the discharge flow path inside the discharge main body 2, making it possible to discharge the content liquid to the outside of the container 1. In the closed state, the opening / closing lid part 25 moves downward to close the top opening 51a, so that the discharge flow path inside the discharge main body part 2 is closed by the opening / closing lid part 25. This blocks the discharge of the content liquid to the outside of the container 1.

[0035] In this manner, the container 1 of this embodiment is switched between an open state and a closed state by rotating the discharge main body 2 (nozzle head 20). Such a rotating operation is performed while the operating cylinder 27 of the nozzle head 20 is held by hand or the like. In the container 1 of this embodiment, the position in the height direction Z of the nozzle head portion 20 (ejection main body portion 2) changes between the open and closed states, but the positions in the height direction Z of the cap member 5 and the container body 10 do not change (see Figures 4 and 5).

[0036] In the container 1 of this embodiment, switching between an open state and a closed state is performed by rotating the nozzle head portion 20 by 90°. More specifically, the angular range (rotation range) within which the nozzle head portion 20 rotates is restricted to an angular range of 90° by the head side stopper piece 28 formed in the nozzle head portion 20 and a pair of cap side stopper pieces 53a, 53a formed on the outer circumferential surface of the head mounting tube portion 53. The head side stopper piece 28 is formed on an inner peripheral wall of the head body 21a that is radially farther from the nozzle portion 22 than the downward cylindrical portion 24, and protrudes radially inward. The head side stopper piece 28 is formed on the rear part of the head body 21a, and straddles the head body 21a and the intermediate cylindrical portion 26 in the height direction Z. The pair of cap side stopper pieces 53a, 53a are formed at positions spaced apart by 90° in the outer circumferential direction of the head mounting tube portion 53, and protrude radially outward from the outer circumferential surface of the head mounting tube portion 53. One cap side stopper piece 53a is disposed at a position where the container 1 is in an open state when the nozzle head portion 20 is rotated, and the other cap side stopper piece 53a is disposed at a position where the container 1 is in a closed state when the nozzle head portion 20 is rotated.

[0037] In the rotation operation of the nozzle head portion 20 of this embodiment, the head side stopper piece 28 moves along the outer circumferential surface of the head mounting tube portion 53 as the nozzle head portion 20 rotates, and comes into contact with one of the pair of cap side stopper pieces 53a, 53a, thereby restricting the range of movement. That is, when the nozzle head portion 20 is rotated, the head side stopper piece 28 moves in the circumferential direction between the pair of cap side stopper pieces 53a, 53a. With this configuration, the rotation of the nozzle head portion 20 can be restricted within an angular range of 90°, making it easier to open and close the container 1.

[0038] In addition, in the container 1 of this embodiment, the cap member 5 and the discharge main body 2 are attached to and detached from the container body 10 by gripping and rotating the enlarged diameter skirt portion 55 of the cap member 5. As described above, the cap member 5 is attached to the neck portion 14 by screwing the female thread ridge 54b and the male thread ridge 14a, and the cap member 5 can be removed from the neck portion 14 by releasing the screwing. By removing the cap member 5 and the discharge main body 2 attached thereto from the neck portion 14 of the container body 10 in this manner, the container 1 of this embodiment can remove the cap member 5 and the discharge main body 2 attached thereto from the neck portion 14 of the container body 10.

[0039] In the container 1 of this embodiment, the discharge flow path of the liquid content in the discharge main body 2 can be opened and closed by rotating the nozzle head portion 20, and the cap member 5 is attached to the neck portion 14 in a freely detachable manner by rotating the enlarged diameter skirt portion 55 of the cap member 5. The parts to be gripped by the hand or the like are different for the rotation operation of these members 20 and 55. For example, the opening and closing of the discharge flow path is performed by gripping the operation cylinder portion 27, and the cap member 5 is removed by gripping the enlarged diameter skirt portion 55. In the container 1 of this embodiment, the parts to be gripped during these rotation operations are different in the height direction Z, and the operation methods for the discharge operation and the removal operation can be clearly distinguished. Moreover, by providing the enlarged diameter skirt portion 55 extending downward from the mounting cylinder portion 54, the area to be gripped by the hand becomes wide, and the operation for removing the cap member 5 from the neck portion 14 can be easily performed. Furthermore, since the nozzle head portion 20 and the cap member 5 can be prevented from rotating together when the liquid content is discharged, the unintended removal (misoperation) of the cap member 5 can be effectively prevented. Due to these effects, the container 1 of this embodiment has excellent universal design. In addition, since the cap member 5 and the discharge body 2 are detachably attached to the neck portion 14, it is possible to refill the liquid content into a used container body 10, or to replace a used container body 10 with a container body 10 containing the liquid content. This makes it possible to reuse a part or all of the container 1, thereby reducing the environmental impact. Thus, the container 1 of this embodiment has excellent operability when discharging the content liquid, while the cap member 5 is detachable from the container body 10 (neck portion 14).

[0040] To facilitate the rotation operation when discharging the content liquid, the length L1 (see FIG. 4) of the operating cylinder 27 in the height direction Z is preferably 7 mm or more and 40 mm or less, and more preferably 10 mm or more and 30 mm or less. In order to facilitate the rotation operation when removing the cap member 5 from the neck portion 14, the length L2 (see Figure 4) of the expanded skirt portion 55 in the height direction Z is preferably 5 mm or more and 40 mm or less, and more preferably 10 mm or more and 20 mm or less.

[0041] From the viewpoint of further suppressing the co-rotation of the nozzle head portion 20 and the cap member 5, it is preferable that the rotation torque of the rotation operation gripping the enlarged diameter skirt portion 55 of the cap member 5 is greater than the rotation torque of the rotation operation gripping the operating cylindrical portion 27 of the nozzle head portion 20. The rotation operation gripping the enlarged diameter skirt portion 55 is the rotation operation when removing the cap member 5 from the neck portion 14, and the rotation operation gripping the operating cylindrical portion 27 is the rotation operation when discharging the content liquid. From the same viewpoint as above, it is preferable that the rotation torque of the rotating operation is within the following range. The range of the rotation torque shown below is premised on the fact that the rotation torque of the rotating operation in which the operation cylindrical portion 27 of the nozzle head portion 20 is gripped is greater than the rotation torque of the rotating operation in which the enlarged diameter skirt portion 55 is gripped. The difference between the rotational torque of the rotation operation gripping the expanded skirt portion 55 and the rotational torque of the rotation operation gripping the operating cylindrical portion 27 is preferably 20 N·cm or more and 200 N·cm or less, more preferably 40 N·cm or more and 150 N·cm or less, and even more preferably 40 N·cm or more and 100 N·cm or less. The rotational torque for the rotation operation while gripping the expanded diameter skirt portion 55 is preferably 50 N·cm to 250 N·cm, more preferably 50 N·cm to 200 N·cm, and even more preferably 60 N·cm to 150 N·cm. The rotational torque for rotating the cylindrical operation portion 27 while gripping it is preferably 10 N·cm or more and 80 N·cm or less, and more preferably 20 N·cm or more and 60 N·cm or less. The rotational torque can be measured using a digital torque meter (TNP-5, Nidec-Shimpo Corporation).

[0042] As described above, in the container 1 of this embodiment, the top surface 13 of the container body 10 has an elliptical shape in a plan view (see FIG. 7), and the expanding skirt portion 55 has an elliptical shape in horizontal cross section (see FIG. 8). In this case, it is preferable that a positioning stopper 19 for restricting the rotation of the expanding skirt portion 55 is formed at the base of the neck portion 14. In the present embodiment, the neck portion 14 has a pair of positioning stoppers 19 formed on the upper surface of the base step portion 15 (see Figs. 6 and 7). The pair of positioning stoppers 19 are formed on the minor axis of the top surface portion 13 having an elliptical shape in plan view in the circumferential direction of the base step portion 15, and face each other in the radial direction. When the cap member 5 is attached to the neck portion 14, the positioning stoppers 19 come into contact with the inner protruding piece 56 that moves in the circumferential direction along the outer circumferential surface of the neck portion 14 on the base step portion 15, thereby easily aligning the peripheries of the top surface portion 13 and the enlarged diameter skirt portion 55. In this case, the cap member 5 is attached to the neck portion 14 so that the contours of the top surface portion 13 having an elliptical shape in plan view and the enlarged diameter skirt portion 55 having an elliptical horizontal cross-sectional shape overlap each other.

[0043] In the container 1 of this embodiment, the neck portion 14 has a pair of positioning stoppers 19, and the enlarged skirt portion 55 has an inner protruding piece 56, thereby restricting the rotation of the cap member 5 relative to the neck portion 14. With this configuration, it is possible to prevent the tightening force (torque) required when screwing or unscrewing the neck portion 14 and the mounting cylindrical portion 54 from becoming excessively high, and the operability of attaching and removing the cap member 5 to the neck portion 14 can be further improved. For example, the abutment between the positioning stoppers 19 and the inner protruding piece 56 can prevent the tightening force of the mounting cylindrical portion 54 to the neck portion 14 from becoming excessively high. In this case, the tightening of the mounting cylindrical portion 54 to the neck portion 14 can be easily loosened when removing the cap member 5.

[0044] The ejection main body 2 of the present embodiment is provided with a foaming mechanism that mixes the content liquid with air and ejects the foamed content liquid from the nozzle portion 22. The foaming mechanism may be a known mechanism disclosed in, for example, JP 2018-177281 A. The foaming mechanism of this embodiment is a cylinder section 3 provided inside the discharge main body 2 (see Figs. 2 to 5). The cylinder section 3 of this embodiment includes a cylinder main body 30 and a cylinder lower part 40 that is held in a state of being fitted into the cylinder main body 30. The cylinder section 3 is held in a state where the reduced diameter part 31 of the cylinder main body 30 is inserted into the holding through hole 25a of the opening / closing lid part 25 and is fitted into the opening / closing lid part 25, from the opening tubular part 52 of the cap member 5 to the vicinity of the lower end of the neck part 14 in the height direction Z (see Fig. 4).

[0045] The cylinder body 30 has a cylindrical base cylinder portion 33, a generally conical reduced diameter portion 31 protruding upward from the base cylinder portion 33, and a main body side cylinder body 35 inserted into the base cylinder portion 33 and hanging down (see FIG. 4). The reduced diameter portion 31 has an upper fitting portion 31a and a side opening cylinder portion 31b extending downward from the lower end edge of the upper fitting portion 31a. In the reduced diameter portion 31, the upper fitting portion 31a is a portion that is inserted into the holding through hole 25a of the opening / closing lid portion 25 in the cylinder body 30, and the outer peripheral surface of the upper fitting portion 31a is in close contact with the inner peripheral surfaces of the holding through hole 25a and the inner cylinder portion 25c. The side opening cylinder portion 31b has openings at radially opposing positions on the outer peripheral surface, and the internal spaces of the opening cylinder portion 52 and the cylinder body 30 communicate with each other through the openings.

[0046] The base cylindrical portion 33 has an inner diameter corresponding to the outer diameter of the upper end portion of the main body side cylinder 35, and the main body side cylinder 35 is inserted from below into the base cylindrical portion 33 and fitted therein. A valve fixing portion 33a having an L-shaped cross section that protrudes radially outward is formed on the outer circumferential surface of the base cylindrical portion 33. A plurality of valve fixing portions 33a are formed along the circumferential direction of the base cylindrical portion 33, and a check valve 34 is fixed between the valve fixing portion 33a and the base cylindrical portion 33 by fitting. The check valve 34 has a fitting base fixed between the valve fixing part 33a and the base cylindrical part 33, and an annular membrane-shaped valve part extending radially outward from the fitting base. The valve part of the check valve 34 has elastic deformation properties, and opens or blocks the discharge flow path of the cap member 5 and the neck part 14 as the nozzle head part 20 moves up and down. Specifically, in the open state, the tip of the valve part abuts against the lower end of the head mounting tube part 53 (see FIG. 5). This blocks communication between the internal spaces of the head mounting tube part 53 and the neck part 14. In the closed state, the tip of the valve part is separated from the lower end of the head mounting tube part 53, so that the internal spaces of the head mounting tube part 53 and the neck part 14 communicate with each other. In this way, the check valve 34 prevents the liquid contents from flowing directly from the neck portion 14 into the cap member 5 in the open state, and recovers the liquid contents in the cap member 5 directly into the neck portion 14 in the closed state.

[0047] On the outer circumferential surface of the main body cylinder 35, fitting pieces 35c having an L-shaped cross section that protrude radially outward are formed intermittently in the circumferential direction below the check valve 34. In the closed state, the content liquid in the cap member 5 flows into the neck portion 14 through gaps between the fitting pieces 35c in the circumferential direction.

[0048] Furthermore, a fixing portion 35d having an L-shaped cross section that protrudes radially outward is formed on the outer peripheral surface of the main body side cylinder 35. The fixing portion 35d is provided in a circumferentially continuous ring shape or intermittently in the circumferential direction. The upper end of the outer cylindrical portion 41 of the cylinder lower portion 40 is disposed between the main body side cylinder 35 and the fixing portion 35d, and the outer cylindrical portion 41 is aligned with the outer peripheral surface of the main body side cylinder 35 to hold the cylinder lower portion 40.

[0049] The upper end of the main body side cylinder 35 is fitted into the base cylindrical portion 33 and extends downward from the base cylindrical portion 33 (see FIG. 4). The internal discharge flow path of the main body side cylinder 35 below the portion fitted into the base cylindrical portion 33 is blocked by a foaming member 35a. Any material capable of foaming the content liquid can be used as the foaming member 35a without any particular limitation, and examples of the foaming member include a porous material such as a sponge and a mesh laminate formed by overlapping a plurality of meshes.

[0050] The main body side cylinder 35 has a lower portion extending downward from a portion where the foaming member 35a is located (hereinafter also referred to as the "foaming portion"). The inner diameter of the lower portion is smaller than the inner diameter of the foaming portion, and the mixing chamber 35b is located directly below the foaming member 35a. The main body side cylinder 35 has an insertion portion 36 below the mixing chamber 35b. The insertion portion 36 is connected to a connecting piece that protrudes obliquely radially inward from the inner peripheral surface of the lower portion, and has a columnar shape that extends downward from the tip of the connecting piece. A plurality of connecting pieces are formed at intervals in the circumferential direction of the insertion portion 36. The lower end of the insertion portion 36 is inserted inside the inner cylinder portion 43 of the cylinder lower portion 40.

[0051] An opening is provided in a portion of the circumference of the lower end of the main body side cylinder 35. This opening overlaps with an opening provided in the lower end of the outer cylinder part 41 of the cylinder lower part 40, and serves as an air inlet 61 that introduces air from the storage space S into the cylinder main body 30.

[0052] The cylinder lower part 40 has an outer cylinder part 41, a lower cylinder part 42 extending downward from the lower end part of the outer cylinder part 41, and an inner cylinder part 43 arranged radially inward of the outer cylinder part 41 and extending upward from the bottom part of the outer cylinder part 41 (see FIG. 4). The main body side cylinder part 35 is inserted between the outer cylinder part 41 and the inner cylinder part 43, and the inner cylinder part 43 is arranged with a gap between it and the main body side cylinder part 35. This gap communicates with the air inlet port 61 and serves as an introduction flow path for introducing air into the main body side cylinder part 35.

[0053] The inner cylindrical portion 43 has ribs 44 formed on its inner circumferential surface, and the ribs 44 support the insertion portion 36 in the main body side cylinder 35 from the radially outer side. The ribs 44 are provided intermittently in the circumferential direction of the inner cylindrical portion 43. The lower cylindrical portion 42 has an internal space that communicates with the inner cylindrical portion 43, and a liquid supply pipe 60 is inserted and held within the lower cylindrical portion 42.

[0054] The liquid supply pipe 60 extends from the lower tubular portion 42 to the storage space S of the body 11. The liquid supply pipe 60 has an outer diameter corresponding to the inner diameter of the lower tubular portion 42, with one end connected to the inside of the main body side cylinder 35 and the other end reaching the vicinity of the bottom 16 of the container body 10. When the body 11 of the container body 10 is pressed and deformed (squeezed), the internal pressure of the body 11 increases, and the content liquid in the storage space S is introduced into the main body side cylinder 35 via the liquid supply pipe 60.

[0055] The container 1 of this embodiment expels the liquid content within the container body 10 to the outside as bubbles, as described below. First, the operating cylinder portion 27 of the nozzle head portion 20 is grasped by hand or the like, and the nozzle head portion 20 is rotated from the closed state to the open state. As a result, the internal spaces of the nozzle head portion 20, the cap member 5, and the cylinder portion 3 are communicated, and the discharge flow path formed by these internal spaces is opened. Next, the body 11 is held by hand or the like and pressed (squeezed) to increase the internal pressure of the storage space S in the body 11. As a result, the liquid content stored in the storage space S is discharged as foam to the outside of the container 1 through the discharge flow path formed by the internal space of the cylinder part 3, the cap member 5, and the nozzle head part 20 by the internal pressure. Specifically, the liquid content is supplied from the storage space S to the inside of the inner tube part 43 through the liquid supply pipe 60, and is introduced into the mixing chamber 35b of the main body side tube body 35 through the gap between the connecting pieces connecting the insertion part 36. In addition, due to the increase in the internal pressure, air in the storage space S is introduced into the mixing chamber 35b through the air inlet 61 through the gap between the inner tube part 43 and the main body side tube body 35. In the mixing chamber 35b, the introduced liquid content and the air are mixed, and the liquid content foams. The content liquid foamed in the mixing chamber 35b is further foamed by passing through the foaming member 35a, and is sent from the main body side cylinder 35 to the side opening cylinder portion 31b of the reduced diameter section 31, the inside of the opening cylinder portion 52, the outer through hole 25b, the head main body 21a, and the protrusion portion 21b, in that order, passes through the foaming member 23, and is discharged from the discharge outlet of the nozzle portion 22.

[0056] The ejection main body 2 and the cap member 5 in the above-described embodiment are molded products made of synthetic resin such as polypropylene or polyethylene, or bioplastic such as polylactic acid, and are preferably formed by injection molding.

[0057] The container of the present invention is not limited to the embodiment shown in Figures 1 to 9. Another embodiment of the container according to the present invention will be described below. In the following, the other embodiment will be described mainly with respect to components different from the embodiment shown in Figures 1 to 9, and similar components will be given the same reference numerals and description will be omitted. For components that are not particularly described, the description of the embodiment shown in Figures 1 to 9 will be applied as appropriate.

[0058] 10, the nozzle portion 22a has a discharge port 221 and a plurality of slits 222 extending along the axial direction of the nozzle portion 22a from positions around the discharge port 221. The plurality of slits 222 are continuous with the discharge port 221 and are formed at intervals in the circumferential direction of the discharge port 221. The slits 222 are cutout portions intermittently provided in the circumferential direction of the cylindrical nozzle portion 22a and extend in the axial direction of the nozzle portion 22a. Nozzle portion 22a of this embodiment discharges foam of the content liquid through discharge outlet 221 and a plurality of slits 222 extending radially from said discharge outlet 221, and can form foam having radial ridges corresponding to slits 222. In other words, foam with a high designability can be obtained. As the nozzle portion 22a of this embodiment, the one described in JP 2020-179870 A can be adopted. In order to further improve the shape retention of the foam, the liquid contained in the container 1a preferably contains an anionic surfactant. As such a liquid, the one described in JP 2020-179870 A can be used.

[0059] The container of the present invention may include other components in addition to the components described above. For example, as shown in FIG. 11, the container 1b may include an attachment 7 attached to the nozzle portion 22. The attachment 7 is made of a tubular portion 70 having a substantially cylindrical shape, and includes a porous portion 72 provided at one opening of the tubular portion 70, a flange portion 73 spaced from the one opening in the axial direction of the tubular portion 70 and projecting radially outward from the tubular portion 70, and a plurality of second openings 71b formed at intervals in the circumferential direction of the tubular portion 70, which are continuous with the other opening 71a serving as an outlet. The attachment 7 is attached in a state in which the end where the porous portion 72 is provided corresponds to the inner diameter of the outlet of the nozzle portion 22. That is, the attachment 7 is connectable to the outlet of the nozzle portion 22. The attachment 7 is connected to the nozzle portion 22 so that the axial direction of the tubular portion 70 is horizontal or inclined downward relative to the horizontal direction. The flange portion 73 has an outer diameter larger than that of the cylindrical portion 70 , and regulates the amount of movement of the attachment 7 when the attachment 7 is inserted into the nozzle portion 22 . The porous portion 72 in the attachment 7 is a mesh-like film having a plurality of through holes. By making the mesh size of the through holes in the porous portion 72 smaller than those of the foam control member 23 and the foaming member 35a, the bubbles of the content liquid passing through the porous portion 72 can be made finer. The film forming the porous portion 32 can be made of, for example, nylon, polyester, or the like.

[0060] In the container 1b of this embodiment, an opening 71a (hereinafter also referred to as "first opening 71a") located on the opposite side of the porous portion 72 in the axial direction of the attachment 7 serves as a discharge port for the liquid contained in the container 1b. In the attachment 7, second openings 71b formed intermittently in the circumferential direction of the cylindrical portion 70 extend in the axial direction of the cylindrical portion 70 and are continuous with the first openings 71a (see FIG. 11). Alternatively, the attachment 7 may have one second opening 71b. The container 1b of this embodiment is provided with the above-mentioned attachment 7, so that it can discharge fine foam and improve the shape retention of the foam. In addition, the foam can be formed in a desired shape by the flow of the foam passing through the first opening 71a, which serves as the discharge outlet, and the second opening 71b extending in the axial direction of the cylindrical portion 70. This can improve the appearance of the foam. As the attachment 7 of this embodiment, the attachment described in International Publication No. 2020 / 110331 can be adopted.

[0061] The present invention is not limited to the above-described embodiment and can be modified as appropriate. For example, in the above-described embodiment, the top surface 13 of the container body 10 has an elliptical shape in a plan view, and the expanding skirt portion 55 has an elliptical horizontal cross-sectional shape, but the plan view shape of the top surface 13 and the horizontal cross-sectional shape of the expanding skirt portion 55 are not limited to an ellipse, and may be a circle, a polygon such as a rectangle, or the like.
