Abstract
Description
Technology Field
[0001] The present invention relates to a stick-type container, and more specifically, to a stick-type container that allows the contents to be completely consumed without any residue. Background Technology
[0002] Stick-type products refer to products that utilize a stick material in which a composition containing necessary ingredients is solidified into a solid form. The stick-type container for this purpose is generally designed to store most of the stick material inside the container, but allows the user to manipulate it so that only a portion is exposed to the outside as needed. In other words, as the stick-type product is used, the exposed upper part of the stick material is consumed and gradually wears down, causing its height to decrease; the stick container then moves the stick material higher to maintain the exposed state. Recently, in addition to cosmetics such as lipsticks and lip balms, products for various uses, such as deodorants, glue sticks, and ointments, are being provided in stick form.
[0003] The contents constituting the stick material are designed to be applied to the target area and are not produced to be excessively hard; therefore, they do not possess high strength in themselves. To prevent the stick material from breaking or detaching, a typical stick-type container is equipped with a cup-shaped holder portion that surrounds the bottom of the stick material. This portion surrounding the bottom of the stick material extends upward by a certain height to allow the stick material to be stably fixed. However, since such a cup-shaped portion surrounds the stick material, it is difficult to use the contents inside the cup portion. That is, even if the stick material is moved upward to be exposed outside the container, the cup-shaped holder portion moves upward along with it, hindering the user from using the contents of the stick material. Consequently, the remaining contents are ultimately unused and discarded. The problem to be solved
[0004] Therefore, the present invention is derived to solve the aforementioned problems, and one aspect of the present invention is to provide a stick-type container that allows the contents to be completely consumed without any residue.
[0005] Another aspect of the present invention is to provide a stick-type container that can increase user convenience.
[0006] Other objects of the present invention will become more apparent through the embodiments described below. means of solving the problem
[0007] A stick-type container according to one aspect of the present invention comprises: a shell member having an inner shell space that extends in the vertical direction and is open to the upper and lower sides; a holder member having a first outer screw portion that is arranged within the shell space in a manner that allows relative movement in the vertical direction relative to the shell member but does not allow relative rotation, and has an inner holder space that is open to the upper side and a screw space that is open to the lower side; and a dial member having a second outer screw portion and a first inner screw portion, wherein at least a portion thereof is disposed in the screw space so that the second outer screw portion engages with the first outer screw portion. A jack screw member may be provided, comprising a dish and a shaft, wherein the dish supports the solid contents on its upper side so that the solid contents are located within the holder space, and the dish is arranged in such a manner that relative movement in the vertical direction relative to the shell member within the holder space is allowed but relative rotation is not allowed, and the shaft extends downward from the dish and includes a second inner screw portion, wherein the second inner screw portion is configured to mesh with the first inner screw portion.
[0008] A stick-type container according to one aspect of the present invention may have one or more of the following embodiments. For example, the first inner screw portion may include a meshing projection formed on the upper part of the dial member, and the second inner screw portion may include a screw thread formed on the outer circumference of the shaft over a predetermined length along the vertical direction.
[0009] A signal projection may be formed at a predetermined position on the shaft, and the signal projection may be formed between the screw threads. A signal groove may be formed on the inner side of the meshing projection. The meshing projection may be formed with an inclination corresponding to the screw threads. Effects of the invention
[0010] According to the means for solving the problem of the present invention as described above, various effects including the following can be expected. However, the present invention is not required to exhibit all of the following effects to be valid.
[0011] According to one embodiment of the present invention, even after a holder member that partially supports solid contents moves to a maximum height, a jack screw member that supports the contents together can move further upward, making it possible to completely consume the contents without any remaining amount.
[0012] According to another embodiment of the present invention, the structure of the signal protrusion and the signal groove enables the user to perceive the point in time when the jack screw member moves independently. As a result, the user can know that the remaining amount of contents has been significantly reduced and can also understand that more caution is required when using the remaining contents.

[0014] The present invention is capable of various modifications and may have various embodiments; specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the present invention to specific embodiments, and it should be understood that it includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the present invention. In describing the present invention, detailed descriptions of related prior art are omitted if it is determined that such detailed descriptions may obscure the essence of the present invention.
[0015] The terms used in this application are used merely to describe specific embodiments and are not intended to limit the invention. The singular expression includes the plural expression unless the context clearly indicates otherwise. In this application, terms such as "comprising" or "having" are intended to specify the presence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.
[0016] Terms such as "first," "second," etc., may be used to describe various components, but said components should not be limited by said terms. These terms are used solely for the purpose of distinguishing one component from another.
[0017] Hereinafter, embodiments according to the present invention will be described in detail with reference to the attached drawings. In describing with reference to the attached drawings, identical or corresponding components are given the same reference number regardless of the drawing symbols, and redundant descriptions thereof will be omitted.
[0018] For convenience of explanation, expressions such as "upper side" and "lower side" are used in this specification. In the following description, "upper side" is intended to refer to the direction in which the contents are exposed in the stick-type container (1000), and "lower side" is intended to refer to the opposite direction. Of course, when actually using the stick-type container (1000) according to one embodiment of the present invention, the upper direction mentioned in the specification may not coincide with the actual upper direction.
[0019] FIG. 1 is an exemplary perspective view showing a stick-type container (1000) according to an embodiment of the present invention. FIG. 2 is an exploded perspective view of the stick-type container (1000), and FIG. 3 and FIG. 4 are cross-sectional views of the stick-type container (1000) of FIG. 1 taken along lines AA' and BB', respectively.
[0020] A stick-type container (1000) according to one embodiment of the present invention corresponds to a container that accommodates solid contents (not shown) in the form of a stick material so that a user can use it. Referring to FIGS. 1 to 4, a stick-type container (1000) according to one embodiment of the present invention may largely include a shell member (100), a holder member (200), a dial member (300), and a jack screw member (400). Of course, the stick-type container (1000) may further include other components such as an overcap and a bottom case. Each component of the stick-type container (1000) is described in more detail below.
[0021] FIGS. 5 and FIGS. 6 are perspective views of a shell member (100) of a stick-type container (1000) according to an embodiment of the present invention, viewed from above and below, respectively.
[0022] The shell member (100) can be extended in the vertical direction to form a shell space (160) inside. The shell space (160) can be opened to the top and bottom, and the main parts of the holder member (200), dial member (300), and jack screw member (400) can be accommodated inside, and in particular, solid contents (not shown) can be accommodated in the upper part of the shell space (160).
[0023] In some embodiments of the present invention, the shell member (100) may be divided into a shell upper portion (110) and a shell lower portion (120). The shell lower portion (120) may be inserted and coupled, for example, into a lower case (not shown), and the shell upper portion (110) may be exposed above the lower case. Of course, if the stick-type container (1000) further includes an overcap (not shown), the overcap (not shown) may cover the shell upper portion (110).
[0024] When the shell lower portion (120) is coupled to a lower case, etc., the shell lower portion (120) may have a smaller outer diameter than the shell upper portion (110). Additionally, one or more coupling protrusions and / or coupling grooves may be formed on the shell lower portion (120) to couple the shell member (100) to the lower case, etc. Although the drawing depicts such coupling protrusions (122) as being formed in an annular shape over the entire outer surface of the shell lower portion (120), since the shell member (100) is not required to rotate relative to the lower case, the coupling protrusions and / or coupling grooves may be formed in a non-continuous shape.
[0025] One or more coupling protrusions and / or coupling grooves may also be formed in the shell lower portion (120) to connect the shell member (100) to the dial member (300). In the drawing, such coupling grooves (124) are formed over the entire inner circumference of the shell lower portion (120) to form an annular shape. Since the dial member (300) must be rotatably connected, it may be advantageous for the coupling protrusions and / or coupling grooves for this purpose to be formed in an annular shape. Additionally, although the drawing shows a structure in which the coupling grooves (124) are formed on the inner circumference of the shell lower portion (120) so that the dial member (300) is connected to the inside of the shell lower portion (120), a structure in which the coupling protrusions and / or coupling grooves are formed on the outer circumference of the shell lower portion (120) and the dial member (300) is connected to the outside of the shell lower portion (120) is also possible.
[0026] A dial member (300) is rotatably coupled to the lower part of the shell member (100). For this purpose, it may be advantageous for the shell lower part (120) to have a circular cross-section as shown in the drawing. Meanwhile, the shell upper part (110) does not rotate itself and is not coupled to other rotating components, so it does not necessarily have to have a circular cross-section.
[0027] A guide slot (130) extending along the vertical direction may be formed at a designated location of the shell member (100). A guide projection (230) of the holder member (200) may be inserted into the guide slot (130). The guide slot (130) and the guide projection (230) may not allow the holder member (200) to rotate relative to the shell member (100), but may allow it to move along the vertical direction. The horizontal width of the guide slot (130) may correspond to the horizontal width of the guide projection (230), and the vertical length of the guide slot (130) may correspond to the distance the holder member (200) can move along the vertical direction.
[0028] FIGS. 7 and FIGS. 8 are perspective views of a holder member (200) of a stick-type container (1000) according to an embodiment of the present invention, viewed from above and below, respectively.
[0029] The holder member (200) can support the lower part of solid contents (not shown) together with the jack screw member (400). The holder member (200) is placed within the shell space (160) and can be configured to move along the up and down direction by user operation.
[0030] The holder body (210) of the holder member (200) is formed in a hollow shape, thereby forming a space inside. An upper holder space (240) and a lower screw space (260) may be formed inside the holder body (210). A solid content (not shown) may be accommodated in the holder space (240), and a part of the dial member (300) may be placed in the screw space (260). In the example illustrated in the drawing, a step (250) with a through hole formed inside is formed at the boundary between the holder space (240) and the screw space (260), and the holder space (240) and the screw space (260) may communicate with each other through the through hole. In some embodiments of the present invention, the step (250) may be omitted, and the holder space (240) and the screw space (260) may form a single space. That is, in some embodiments, the holder space (240) and the screw space (260) may not be clearly distinguished.
[0031] Support protrusions (212, 214) may be formed on the outer side of the holder body (210). The support protrusions (212, 214) may be implemented in a form that protrudes slightly outward, having a diameter that is slightly larger than the rest of the holder body (210). The support protrusions (212, 214) contact the inner surface of the shell member (100) to help maintain the holder member (200) in a state of relative alignment with respect to the shell member (100), while keeping the frictional force generated between the holder member (200) and the shell member (100) low.
[0032] A guide projection (230) may also be formed on the outer side of the holder body (210). When the holder member (200) is coupled to the shell member (100), the guide projection (230) of the holder member (200) may be inserted into the guide slot (130) of the shell member (100). The horizontal width of the guide projection (230) may be set to correspond to the width of the guide slot (130), and consequently, the guide slot (130) and the guide projection (230) may not allow the holder member (200) to rotate relative to the shell member (100), while allowing it to move along the vertical direction.
[0033] Although the drawing shows an example in which the holder body (210) is formed in a cylindrical shape, the holder member (200) does not rotate itself and is not combined with other rotating components, so it is not necessary to have a circular cross-section. If the holder body (210) and the shell space (160) have non-circular cross-sections, their shapes themselves will not allow rotation of the holder member (200), so in this case, the guide slot (130) and the guide projection (230) may be omitted. However, as in the embodiment shown in the drawing, a structure utilizing the guide slot (130) and the guide projection (230) may be more advantageous in terms of improving the aesthetics of the product and reducing friction between the holder member (200) and the shell member (100).
[0034] Referring to FIG. 7, one or more fixing pins (242) may be formed on the upper portion of the holder member (200). The fixing pins (242) may protrude inward from the inner surface of the holder body (210) at a position corresponding to the holder space (240) and serve to support solid contents (not shown) within the holder space (240). The length of the fixing pins (242) protruding inward may decrease as they move upward as shown in FIG. 7, or may be maintained at the same length at the upper and lower portions.
[0035] The holder member (200) may include a first outer screw portion. The first outer screw portion of the holder member (200) may be configured to engage and interact with the second outer screw portion of the dial member (300). That is, at least one of the first outer screw portion and the second outer screw portion may be configured in the form of screw threads, and the first outer screw portion and the second outer screw portion may form a type of lead screw, so that when rotational force is applied to the dial member (300), it can be converted into a force that moves the holder member (200) upward.
[0036] In the example illustrated in the drawing, the first outer screw portion of the holder member (200) is implemented in the form of a meshing projection (270), and the second outer screw portion of the dial member (300) is implemented in the form of a screw thread (370). Of course, it is also possible to implement both the first outer screw portion and the second outer screw portion in the form of a screw thread.
[0037] As illustrated in FIGS. 7 and 8, the meshing projection (270) can be formed with a slope corresponding to the screw thread (370). That is, in FIG. 7, the right side of the meshing projection (270) is lower than the left side, and in FIG. 8, the left side of the meshing projection (270) is formed lower than the right side. A structure in which the meshing projection (270) has such a slope enables smoother rotation when the meshing projection (270) is engaged with the screw thread (370). Of course, it is also possible to form the meshing projection (270) without a slope as long as the meshing projection (270) can be positioned between the screw threads (370).
[0038] A clearance hole (275) may be formed in the holder body (210). The clearance hole (275) may extend to the upper part of the screw space (260) and may not reach the part corresponding to the holder space (240). The clearance hole (275) prevents the holder body (210) from becoming excessively rigid, thereby allowing the holder member (200) and the dial member (300) to rotate more smoothly relative to each other. Meanwhile, in the example illustrated in the drawing, a meshing projection (270) is formed at the lower part of the clearance hole (275). This structure also serves to make the molding of the holder member (200) more convenient.
[0039] FIGS. 9 to 11 are perspective views of a dial member (300) of a stick-type container (1000) according to an embodiment of the present invention, viewed from above and below.
[0040] The dial member (300) corresponds to the part where the user applies rotational force for operating the stick-type container (1000). To this end, the dial member (300) may be rotatably coupled to the lower part of the shell member (100). Additionally, the dial member (300) may include a second outer screw part that engages with the first outer screw part of the holder member (200), so that the rotational force applied by the user is transmitted as an up-and-down movement of the holder member (200).
[0041] Referring to FIGS. 9 to 11, the dial member (300) may include a sleeve (310) and a rotational coupling part (320). The sleeve (310) includes a second outer screw part and a first inner screw part and corresponds to a part that interacts with the holder member (200) and the jack screw member (400), and the rotational coupling part (330) corresponds to a part that rotatably connects the dial member (300) to the shell member (100).
[0042] The sleeve (310) can be inserted into the screw space (260) of the holder member (200) and may have a hollow cylindrical shape overall. The sleeve space (360) formed on the inside of the sleeve (310) may be open to the top and bottom. One or more clearance slits (315) may be formed in the sleeve (310), and the clearance slits (315) may extend downward from the top of the sleeve (310). As shown in FIG. 9, when multiple clearance slits (315) extend from the top to the bottom of the sleeve (310), the sleeve (310) may be viewed as being divided into several parts having an arc-shaped cross-section. The clearance slits (315) prevent the sleeve (310) from becoming excessively rigid, thereby allowing the holder member (200) and the dial member (300) to rotate more smoothly relative to each other.
[0043] The sleeve (310) may include a second outer screw portion, which may be configured to engage and interact with the first outer screw portion of the holder member (200). In the example illustrated in the drawing, the second outer screw portion of the dial member (300) is implemented in the form of a screw thread (370) formed on the outer circumference of the sleeve (310), which engages with the engaging projection (270) of the holder member (200). The first outer screw portion and the second outer screw portion can convert the rotational force applied by the user into upward movement of the holder member (200).
[0044] The sleeve (310) may also include a first inner screw portion, which may be configured to engage and interact with the second inner screw portion of the jack screw member (400). That is, at least one of the first inner screw portion and the second inner screw portion may be configured in the form of a screw thread, and the first inner screw portion and the second inner screw portion may form a type of lead screw. When rotational force is applied to the dial member (300), the first and second inner screw portions may convert the rotational force into a force that moves the jack screw member (400) upward. The pitch of the first and second inner screw portions can be designed by taking into account the pitch of the first and second outer screw portions, specifically, when the dial member (300) is rotated once, the upward and downward movement distance of the jack screw member (400) due to the interaction of the first and second inner screw portions can be designed to be the same as the upward and downward movement distance of the holder member (200) due to the interaction of the first and second outer screw portions.
[0045] In the example illustrated in the drawing, the first inner screw portion of the dial member (300) is implemented in the form of a meshing projection (380), and the second inner screw portion of the jack screw member (400) is implemented in the form of a screw thread (480). Of course, it is also possible to implement both the first inner screw portion and the second inner screw portion in the form of a screw thread.
[0046] In the example illustrated in the drawing, a seating portion (312) is formed on the upper part of the sleeve (310), and a through hole is formed on the inner side of the seating portion (312) to communicate the sleeve space (360) with the outside. It is preferable that the through hole on the inner side of the seating portion (312) be formed with a size such that the shaft (460) of the jack screw member (400) passes through, but the dish (440) does not. A meshing projection (380) is formed on the inner surface of the seating portion (312) facing the through hole. As described in detail in FIG. 10, the meshing projection (380) may be formed with an incline corresponding to the screw thread (480). A structure in which the meshing projection (380) has such an incline enables smoother rotation when the meshing projection (380) is engaged with the screw thread (480).
[0047] A signal groove (390) may be formed on the inner side of the meshing projection (380). The signal groove (390) may be formed to a size into which the signal projection (490) formed on the shaft (460) of the jack screw member (400) can be inserted.
[0048] The rotational coupling part (320) is a part that rotatably connects the dial member (300) to the shell member (100) and can be implemented in various shapes. In the example illustrated in the drawing, the rotational coupling part (320) includes a support rim (330), an outer rim (340), and an inner rim (350).
[0049] The support rim (330) may extend downward from the first flange (324) protruding outward from the lower part of the sleeve (310). A fixing projection (332) may be formed on the outer surface of the support rim (330). As shown in FIGS. 3 and 4, when the dial member (300) is coupled to the shell member (100), the support rim (330) may be inserted into the inner side of the shell lower part (120), and at this time, the fixing projection (332) may be inserted into the coupling groove (124) of the shell lower part (120). Since the coupling groove (124) is formed over the entire inner surface of the shell lower part (120) to form an annular shape, the coupling groove (124) and the fixing projection (332) allow rotation of the dial member (300) relative to the shell member (100) but do not allow movement in any other direction.
[0050] The outer rim (340) may extend downward from a second flange (334) that protrudes outward from the lower part of the support rim (330). When the dial member (300) is coupled to a component such as a separate rotary knob (not shown), one or more coupling protrusions and / or coupling grooves may be formed on the outer rim (340).
[0051] The inner rim (350) is a portion that extends downward from the inner side of the support rim (330) and the outer rim (340). The inner rim (350) may have a hollow cylindrical shape, and the space inside may be continuous with the sleeve space (360). The inner rim (350) may be useful when a separate rotary knob (not shown) that is directly gripped by the user is attached, and for this purpose, a plurality of connecting pins (352) may be provided. The connecting pins (352) may be used to transmit rotational force applied to the rotary knob (not shown), etc., to the dial member (300) without loss.
[0052] FIGS. 12 and FIGS. 13 are perspective views of a jack screw member (400) of a stick-type container (1000) according to an embodiment of the present invention, viewed from above and below, respectively.
[0053] The jack screw member (400) is a part that supports solid contents (not shown) on its upper side, and is a part that, depending on the user's operation, rises primarily together with the holder member (200), and then rises independently further when the holder member (200) reaches the highest position to expose all of the solid contents (not shown) to the outside. The jack screw member (400) may mainly include a dish (440) and a shaft (460).
[0054] The dish (440) can support solid contents (not shown) on its upper surface. When the jack screw member (400) is assembled to the holder member (200) and the dial member (300), the shaft (460) can be inserted into the screw space (260) through the through hole formed in the step (250) and the through hole formed in the seating portion (312) of the sleeve (310), and the dish (440) can be positioned in the holder space (240).
[0055] When the holder member (200) includes a step (250), the dish (440) can be seated on the step (250). With the dish (440) seated on the step (250) corresponding to the lower part of the holder space (240), the lower end of the solid contents (not shown) can be supported on the upper part of the dish (440) inside the holder space (240). Consequently, the dish (440) can support the lower end of the solid contents (not shown) from below, and the upper part of the holder body (210) can surround the outer surface of the lower end of the solid contents (not shown).
[0056] The dish (440) may be positioned in such a way that the jack screw member (400) is not allowed to rotate relative to the shell member (100), but is allowed to move along the up and down direction. In one embodiment of the present invention, the holder member (200) may be coupled so as not to rotate relative to the shell member (100), and the dish (440) may be positioned so as not to rotate relative to the holder member (200), and consequently, may be positioned so as not to rotate relative to the shell member (100).
[0057] For example, the dish (440) may be formed in a flat shape and one or more fixing slits (442) may be formed. The fixing slits (442) may be formed in a number corresponding to the number of fixing pins (242) provided in the holder member (200) and each may extend to the edge of the dish (440). Even if the holder member (200) includes fixing pins (242) that protrude into the holder space (240), the dish (440) may be inserted into the holder space (240) due to the fixing slits (442) formed in the dish (440). The fixing slits (442) and fixing pins (242) may not allow the dish (440) to rotate relative to the shell member (100) (more specifically, relative to the holder member (100)), but may allow it to move along the up and down direction relative to the shell member (100).
[0058] The shaft (460) can extend downward from the dish (440) and, in a state before solid contents are used, can be positioned within the screw space (260) by passing through the through hole formed in the step (250) and the through hole formed in the seating portion (312) of the sleeve (310).
[0059] The shaft (460) may include a second inner screw portion, which may be configured to engage and interact with the first inner screw portion of the dial member (300). At least one of the first inner screw portion and the second inner screw portion may be configured in the form of a screw thread, and the first inner screw portion and the second inner screw portion may form a type of lead screw.
[0060] In the example illustrated in the drawing, the second inner screw portion of the jack screw member (400) is implemented in the form of a screw thread (480). The screw thread (480) implemented as the second inner screw portion of the jack screw member (400) can be formed over a longer length in the vertical direction compared to the screw thread (370) implemented as the second outer screw portion of the dial member (300). Specifically, the screw thread (480) of the jack screw member (400) can be formed over a length corresponding to the value obtained by adding the length of the holder space (240) to the length in which the screw thread (370) of the dial member (300) is formed in the vertical direction.
[0061] A signal projection (490) may be formed at a predetermined position on the shaft (460). The signal projection (490) may be formed between the screw threads (480) forming the second inner screw portion as shown in FIGS. 12 and 13. According to one embodiment of the present invention, the position where the signal projection (490) is formed may correspond to a height corresponding to the meshing projection (380) on the shaft (460) when the holder member (200) reaches the highest position.
[0062] A stopper projection (462) may be formed at the bottom of the shaft (460). The stopper projection (462) may protrude further outward than the screw thread (480) and prevent the shaft (460) from completely detaching from the sleeve space (360) of the dial member (300). To this end, the stopper projection (462) may be formed to protrude further outward than the through hole formed inside the seating portion (312) of the sleeve (310), as shown in FIG. 4.
[0063] Hereinafter, the operation of a stick-type container (1000) according to an embodiment of the present invention will be described in more detail with reference to FIGS. 1 to 15. FIGS. 14 and FIGS. 15 are cross-sectional views exemplarily showing the state of use of a stick-type container (1000) according to an embodiment of the present invention.
[0064] First, when the stick-type container (1000) is first provided, the shell member (100), holder member (200), dial member (300), and jack screw member (400) may be arranged as shown in FIGS. 2 to 4. The dial member (300) is rotatably coupled to the shell member (100), and the holder member (200) and jack screw member (400) are located at the lowest height and support solid contents (not shown) on their upper portions. The solid contents (not shown) may be provided with a length extending, for example, from the top of the dish (440) to the top of the shell member (100). Of course, depending on the size of the overcap, etc. coupled to the shell member (100), the solid contents (not shown) may be extended to a higher height.
[0065] The holder member (200) can be positioned at the lowest height when the guide projection (230) is inserted into the guide slot (130) of the shell member (100) and the first outer screw portion (measuring projection (270)) is engaged with the second outer screw portion (screw thread (370)) of the dial member (300). At the lowest height at which the holder member (200) can be positioned, the step (250) of the holder member (200) can be seated on the seating portion (312) of the dial member (300). The upper part of the holder member (200) supports solid contents (not shown), and the fixing pin (242) can contact the solid contents (not shown) over a wider surface area to prevent the solid contents (not shown) from escaping from the holder space (240).
[0066] The jack screw member (400) can be positioned at the lowest height when the shaft (460) is inserted into the screw space (260) through the through hole formed in the step (250) and the through hole formed in the seating portion (312) of the sleeve (310), and the second inner screw portion (screw thread (480)) is engaged with the first inner screw portion (meeting projection (380)) of the dial member (300). At the lowest height at which the jack screw member (400) can be positioned, the dish (440) of the jack screw member (400) can be seated on the step (250). Although a fixing pin (242) is formed on the upper part of the holder member (200), a fixing slit (442) is formed in the dish (440) at a position corresponding to the fixing pin (242), so that the jack screw member (400) can move in the up and down direction without rotation.
[0067] When a user wishes to use solid contents (not shown) inside a stick-type container (1000), the user may remove an overcap (not shown) and then rotate the dial member (300) relative to the shell member (100). For example, the user may apply rotational force by holding the dial member (300) or a rotary knob (not shown) attached to the dial member (300) with one hand and the shell member (100) or a lower case (not shown) attached to the shell member (100) with the other hand. Although the present specification describes the shell member (100) as being fixed and the dial member (300) as being rotated, such rotation is relative, and it is obvious that the shell member (100) can be rotated and the dial member (300) can be fixed.
[0068] When the dial member (300) is rotated, the holder member (200) is constrained so as not to rotate relative to the shell member (100) but is coupled so as to be movable in the vertical direction; therefore, the interaction between the first and second outer screw parts provided in the holder member (200) and the dial member (300) causes the holder member (200) to move upward. At the same time, since the jack screw member (400) is constrained so as not to rotate relative to the holder member (200), the interaction between the first and second inner screw parts provided in the dial member (300) and the jack screw member (400) causes the jack screw member (400) to move upward. Although a signal groove (390) is formed on the meshing projection (380) of the dial member (300), the meshing projection (380) is engaged at a position between the screw threads (480), so at this stage, the signal groove (390) does not affect the interaction between the first and second inner screw parts. The upward and downward movement distance of the jack screw member (400) due to the interaction between the first and second inner screw parts may be the same as the upward and downward movement distance of the holder member (200) due to the interaction between the first and second outer screw parts.
[0069] When the holder member (200) and the jack screw member (400) move upward, the solid contents (not shown) supported on their upper portions also move upward. The top of the solid contents (not shown) reaches a position higher than the top of the shell member (100) and is located outside the shell space (160), allowing the user to apply the solid contents (not shown) to the target area. After using the contents, the user may cover the solid contents (not shown) again with an overcap (not shown) or the like as needed.
[0070] As the solid contents (not shown) are used, the solid contents (not shown) are consumed from the top, and as a result, the amount of contents exposed beyond the top of the shell member (100) will decrease. The user may rotate the dial member (300) further as needed to expose more of the solid contents (not shown) to the outside.
[0071] When a significant amount of solid contents (not shown) is consumed and the holder member (200) reaches the highest position it can reach, the stick-type container (1000) can be arranged as shown in FIG. 14. That is, the meshing projection (270) of the holder member (200) reaches the upper part of the screw thread (370) of the dial member (300), so that the holder member (200) can no longer move upward. After this, even if the dial member (300) is rotated, the holder member (200) will not move up or down from that position. In the example shown in FIG. 14, when the holder member (200) reaches the highest position, the top of the holder member (200) is at the same height as the top of the shell member (100), but depending on the embodiment, the top of the holder member (200) may be positioned higher or lower than the top of the shell member (100).
[0072] Up to the arrangement shown in FIG. 14, the jack screw member (400) moves together with the holder member (200), and when the holder member (200) reaches the highest position, the signal projection (490) of the jack screw member (400) can reach the meshing projection (380) of the dial member (300). As the signal projection (490) engages with the meshing projection (380), the meshing projection (380) and the signal projection (490) resist the rotation of the dial member (300) relative to the jack screw member (400), and as the dial member (300) rotates further and the signal projection (490) is inserted into the signal groove (390), the above resistance is suddenly released. The user rotating the dial member (300) tactilely perceives the resistance and the release of the resistance, thereby recognizing that the holder member (200) has reached the highest position.
[0073] In the arrangement illustrated in FIG. 14, if the user rotates the dial member (300) further, the holder member (200) only rotates in place and cannot move further upward. Meanwhile, the jack screw member (400) can move further upward due to the interaction of the first and second inner screw parts after the signal projection (490) is separated from the signal groove (390) by the rotational force applied by the user. This allows the dish (440) of the jack screw member (400) to move further over the step (250) of the holder member (200) as illustrated in FIG. 15, and can lift a small amount of solid contents (not shown) located within the holder space (240). Before the holder member (200) reaches its highest position, the solid contents (not shown) also have a shape that extends long along the vertical direction, so it is required to be supported in a way that surrounds the bottom of the solid contents (not shown), but after the holder member (200) reaches its highest position, the solid contents (not shown) have a significantly reduced length, so they can be supported sufficiently firmly by being supported from below by the dish (440).
[0074] The solid contents (not shown) being lifted can be separated from the fixing pin (242) of the holder member (200) and exposed above the top of the holder member (200) and the shell member (100). In one embodiment of the present invention, the range of movement of the jack screw member (400) can be designed so that the upper surface of the dish (440) can move to a height corresponding to or greater than the top of the holder member (200) and the shell member (100). When the jack screw member (400) moves to a height where the solid contents can be completely consumed, the stopper projection (462) contacts the lower surface of the seating portion (312) to prevent the jack screw member (400) from moving further upward.
[0075] According to some embodiments of the present invention presented above, even after the holder member (200) that partially supports the solid contents moves to a maximum height, the jack screw member (400) that supports the contents together can move further upward, making it possible to completely consume the contents without any remaining amount. The structure of the signal protrusion (490) and the signal groove (390) allows the user to perceive the point at which the jack screw member (400) moves independently. As a result, the user can know that the remaining amount of contents has been significantly reduced and can also understand that more caution is required when using the remaining contents.
[0076] Although the present invention has been described above with reference to one embodiment, those skilled in the art will understand that various modifications and changes can be made to the invention without departing from the spirit and scope of the invention as described in the following claims.
