Description

Refillable stick container

[0001] The present invention relates to a refillable stick-type container, and more specifically, to a stick-type container that can be refilled by separating the container body, the contents of which have been used, from a lower actuator and connecting a new refillable container to the lower actuator.

[0002] Typically, cosmetic containers are designed to accommodate various types of cosmetics and have a structure that allows the cosmetics to be withdrawn from the container. The structure of these containers can vary depending on the nature of the cosmetics contained within.

[0003] For example, if the cosmetic is a solid cosmetic that can maintain a certain shape, the structure of a stick-type cosmetic container may be formed by providing a support plate that supports the lower part of the cosmetic, and raising and lowering the support plate to enable withdrawal of the cosmetic. Specifically, the stick-type cosmetic container may include an outer container and an inner container that are provided to be relatively rotatable, and may have a structure in which, when a user holds the outer container and turns the inner container exposed on one side of the outer container or a dial that operates the inner container, the support plate is raised, thereby lifting the cosmetic and allowing it to be withdrawn to the outside of the outer container.

[0004] Stick-type cosmetic containers like this one have the advantage of allowing you to apply the contents directly to the desired area without getting them on your hands, and are used in a variety of products, including lipsticks, sun sticks, sun balms, and stick-type foundations.

[0005] However, these stick-type containers need to be manufactured in various shapes other than circular ones so that they can be applied over a wider area as needed or to narrow, curved areas. However, if the contents are formed in a non-circular shape, the elevating member that elevates the contents and the dial that rotates the elevating member are integrally combined, making it impossible to separate the elevating member and the dial. Therefore, there is a technical limitation that makes it difficult to manufacture them in a form that allows the contents to be refilled. Therefore, when the contents are used up, the entire stick-type container must be discarded and a new container must be purchased, which increases the purchase cost and causes the problem of waste of resources.

[0006] Therefore, there is a need to develop a refillable stick-type container that is not limited by the shape of the contents and can be replaced with a new container when the contents are exhausted.

[0007] The present invention is intended to solve the above problem, and one embodiment of the present invention provides a stick-type container that can be refilled by separating the container body and the lower actuator when the contents inside the container body are all used up and connecting a new refill container to the lower actuator.

[0008] The technical problems to be achieved in this document are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0009] As a technical means for achieving the above-described technical tasks, a refillable stick-type container according to an embodiment of the present invention includes a container body that accommodates contents therein and guides the contents to be raised and lowered therein; an elevating member accommodated inside the container body and elevating the contents; and a lower driving body that is coupled to a lower portion of the elevating member and includes a dial that rotates the elevating member, wherein the dial is capable of being separated from and coupled to a lower portion of the elevating member, so that the container body and the lower driving body can be mutually separated from and coupled to each other.

[0010] According to one embodiment of the present invention, when the contents inside the main body of the stick-type container according to the present invention are completely exhausted, the main body of the container and the lower body are separated, and a new refill container filled with contents is combined with the separated lower body to perform refilling.

[0011] According to one embodiment of the present invention, the stick-shaped container according to the present invention can be configured such that the dial and the lifting member can be detachably connected, thereby implementing a structure that allows refilling without restrictions on the shape of the contents. For example, the container can be manufactured in a thin, flat, or oval shape to ensure a wide application area and ease of use.

[0012] According to one embodiment of the present invention, the stick-type container according to the present invention can separate the container body and the lower body through a simple operation, such as by pressing the detachable press mark portion formed on both sides of the lower body, so that the refilling operation of the contents can be easily performed.

[0013] According to one embodiment of the present invention, the refillable stick-type container according to the present invention can be filled with contents from the rear side by opening the lower part of the lower drive body.

[0014] According to one embodiment of the present invention, the refillable stick-type container according to the present invention is made of a single series of materials such as PP (plastic), so that it can be disposed of as a whole without having to separate and dispose of parts, making it easy to recycle and having the advantage of being environmentally friendly.

[0015] The effects that can be obtained from the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by a person having ordinary skill in the art to which the present disclosure pertains from the description below.

[0045] The phrases “in one embodiment” and the like appearing in various places throughout this disclosure do not necessarily all refer to the same embodiment.

[0046] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0047] FIG. 1 is a perspective view illustrating a refillable stick-type container according to an embodiment of the present invention, FIG. 2 is an exploded perspective view illustrating a refillable stick-type container according to an embodiment of the present invention in an exploded state, and FIG. 3 is a perspective view illustrating a refillable stick-type container according to an embodiment of the present invention in a more detailed exploded state.

[0048] Referring to FIGS. 1 to 3, a refillable stick-type container (1000) according to one embodiment may include a container body (100) that guides the content (A) to rise and fall inside, a lower actuator (300) that is accommodated inside the container body (100) and includes an elevating member (200) that elevates the content (A), and a dial (320) that is coupled to the lower portion of the elevating member (200) and rotates the elevating member (200). At this time, the dial (320) can be separated from and coupled to the lower portion of the elevating member (200), so that the container body (100) and the lower actuator (300) can be separated from and coupled to each other. Therefore, the user can easily refill the container body (100) by separating the container body (100) in which the contents (A) have been used from the lower drive body (300) and attaching a new refill container to the lower drive body (300).

[0049] According to one embodiment, the contents (A) can be filled inside the container body (100). For example, the stick-shaped container (1000) of the present invention can be formed in a front-filling manner in which the contents (A) are filled through the open upper portion of the container body (100).

[0050] In addition, in the present invention, the filling of the contents (A) can also be accomplished by a back-filling method in which the contents (A) are injected through a through-injection hole (230) formed in the lifting member (200) described later.

[0051] Accordingly, the present invention can fill the contents (A) inside the container body (100) through both front filling and back filling methods.

[0052] According to one embodiment, the content (A) may be a solid, semi-solid, or balm formulation, and may be a formulation that can be filled in a liquid state and solidified into a solid or semi-solid state. According to an embodiment, the content (A) may include cosmetics, external skin agents, medicines, etc. For example, the content (A) may include sunscreen, UV blocker, multi-balm, moisturizing cream, lipstick, foundation, CC cream, shading, BB cream, tone-up cream, etc., but is not limited thereto, and as described above, may include all kinds of substances that can be filled in a liquid state and solidified to form a stick shape and be lifted and released by the stick-type container (1000) of the present invention.

[0053] According to one embodiment, the container body (100) may be formed in a circular or non-circular shape. The stick-type container according to the present invention is configured such that the dial and the lifting member can be detachably coupled, thereby implementing a structure that allows refilling without limitation on the shape of the container body (100). Accordingly, the container body (100) and the contents accommodated therein are not limited to a circular shape and may be manufactured in various shapes. For example, the container body (100) (and / or the contents accommodated therein) may be manufactured in a circular, square, triangular, oval type, etc., and may also be manufactured in a horizontally long and thin shape, a flat shape, etc. so as to have a wide application area and be convenient to use. The present invention is not limited thereto and various shapes of embodiments may be applied.

[0054] According to one embodiment, the container body (100) can guide the content (A) accommodated therein to be raised and lowered therein. That is, the interior of the container body (100) can be formed in a hollow shape so as to provide a space in which the content (A) can be accommodated and a space in which an elevating member (200) described later can be accommodated. For example, the interior of the container body (100) formed in a hollow shape is filled with the content (A), and an elevating member (200) is coupled to the lower portion of the content (A) within the container body (100) so that the content (A) is raised and lowered by the elevating member (200), but the content (A) can be guided within the interior of the container body (100).

[0055] According to one embodiment, a penetration portion (130) may be formed at a lower point of the container body (100). For example, the penetration portion (130) may be formed such that a lower point of the container body (100) is cut so that the upper and lower portions are completely penetrated. One side of the lifting member (200) may be accommodated in the penetration portion (130) of the container body (100) so as to be exposed. That is, the lower portion of the rotation guide (220) described below may be coupled so as to be exposed to the lower portion of the penetration portion (130), so that the rotation guide (220) may be coupled with the dial (320).

[0056] According to one embodiment, the lower part of the container body (100) may be formed to have a narrower width than the upper part so that it can be fitted into the interior of the lower actuator (300) described later. In addition, a receiving groove (not shown) may be formed in the lower part of the container body (100) so that an upper part of the lower actuator (300) can be received. Therefore, when the container body (100) and the lower actuator (300) are coupled, the lower part of the container body (100) is inserted into the inner surface of the lower actuator (300), and the upper part of the lower actuator (300) is inserted into the receiving groove of the container body (100), so that the coupling can be performed without a mutual step.

[0057] According to one embodiment, at least one engaging protrusion (110) may be formed in one area of ​​the container body (100). For example, the engaging protrusion (110) may be formed at a point in the lower portion of the container body (100) formed to have a narrower width than the upper portion as described above, i.e., the portion inserted into the inner surface of the lower actuator (300). In addition, the engaging protrusions (110) may be formed in pairs symmetrically on the front and rear surfaces of the container body (100). These engaging protrusions (110) may be fitted into engaging grooves (311) formed in the lower body (310) of the lower actuator (300) described below, so that the container body (100) and the lower actuator (300) may be fastened.

[0058] According to one embodiment, the container body (100) and the lower actuator (300) may include at least one detachment protrusion (120, 312). When an external force is applied to an area where a detachment protrusion is formed while the container body (100) and the lower actuator (300) are coupled, separation of the container body (100) and the lower actuator (300) may be induced by interference between the detachment protrusions.

[0059] According to one embodiment, the container body (100) may have a detachable protrusion (120) formed in a lower region. For example, the detachable protrusion (120) may be formed on each of the lower sides of the container body (100). This detachment protrusion (120) is formed at a position corresponding to the detachment protrusion (312) formed on the lower body (310) of the lower actuator (300) described later, so that the container body (100) and the lower actuator (300) come into contact with each other when the container body (100) and the lower actuator (300) are coupled, and when the user presses the detachment press mark portion (313) formed on both sides of the lower body (310) described later to separate the container body (100) and the lower actuator (300), the detachment protrusion (120) formed on the container body (100) and the detachment protrusion (312) formed on the lower body (310) push each other, so that the container body (100) and the lower actuator (300) can be easily separated vertically.

[0060] According to one embodiment, the detachment protrusion (120) may be formed to have a certain slope to facilitate the detachment protrusion (312) formed on the lower body (310) described below from repelling each other. That is, when the detachment protrusion (120) formed on the container body (100) is formed to be inclined from the top to the bottom, the detachment protrusion (312) formed on the lower body (310) may be formed to be inclined from the bottom to the top.

[0061] Accordingly, when the detachable protrusions (120, 312) are in contact with each other, they are formed to be in close contact without being separated from each other, and when the container body (100) and the lower drive body (300) are separated by the elasticity of the container, interference occurs and they can push each other out.

[0062] According to one embodiment, an outer cap (500) may be coupled to the outer surface of the container body (100). This outer cap (500) may be formed in a shape that covers the outer surface of the container body (100) to seal the container body (100) when not in use in order to prevent the contents (A) contained inside the container body (100) from drying out by contact with air.

[0063] In one embodiment, an inner cap (400) may be attached to the upper portion of the contents (A). The inner cap (400) may block the contents (A) from contacting air until the user first uses it, thereby keeping the contents moist, and may be removed for use.

[0064] FIG. 4 is a front view and a cross-sectional view showing a refillable stick-type container according to an embodiment of the present invention when viewed from the front, and FIG. 5 is a cross-sectional view showing a state of use of a refillable stick-type container according to an embodiment of the present invention.

[0065] Referring to FIGS. 4 and 5, according to one embodiment, the elevating member (200) is accommodated inside the container body (100) and can elevate the contents (A). For example, the elevating member (200) is coupled to the lower portion of the contents (A) accommodated inside the container body (100), and when the elevating member (200) is rotated by the dial (320) of the lower drive unit (300) described below, the contents (A) can be elevated and protruded out of the container body (100).

[0066] This lifting member (200) may include a lifting body (210) including a contents receiving portion (211) that supports the lower part of the contents (A), a lifting rod (212) that is formed by extending to the lower part of the contents receiving portion (211) and has screw threads formed along the outer periphery, and a rotation guide (220) that receives and connects the lifting rod (212) and has screw threads formed corresponding to the screw threads formed on the lifting rod (212), and is connected to a dial (320) and rotates by the rotation of the dial (320).

[0067] According to one embodiment, the contents receiving portion (211) of the lifting body (210) can support a lower portion of the contents (A). For example, when the contents receiving portion (211) is provided inside the container body (100) and the contents (A) are filled using the inner space of the container body (100) through the through injection hole (230) described later, the contents (A) are filled and solidified from the inner surface of the contents receiving portion (211), so that the contents (A) can be filled and solidified in a form in which they are contained inside the contents receiving portion (211).

[0068] In order to stably fix the solidified contents (A) to the contents receiving portion (211) and prevent them from being separated, a plurality of protrusions may be formed on the inner surface of the contents receiving portion (211).

[0069] According to one embodiment, a lifting rod (212) may be formed to extend to the lower portion of the content receiving portion (211). The lifting rod (212) may have screw threads formed on the outer circumference thereof and may be accommodated and coupled to the interior of a rotation guide (220) to be described later. The lifting rod (212) may be guided by the screw threads formed on the rotation guide (220) when the rotation guide (220) rotates, thereby allowing the lifting rod (212) to ascend and descend relative to the rotation guide (220). For example, when the screw threads formed on the lifting rod (212) are engaged with the screw threads formed on the inner surface of the rotation guide (220), and the rotation guide (220) is rotated by the rotation of the dial (320), the lifting rod (212) may be guided by the screw threads formed on the inner surface of the rotation guide (220), thereby allowing the lifting rod (212) to ascend and descend. Accordingly, the lifting bar (212) is raised and lowered relative to the rotary guide (220), and the lifting body (210) is raised and lowered, so that the contents (A) can be ejected to the upper part of the container body (100).

[0070] According to one embodiment, the rotation guide (220) may have threads formed on its inner surface corresponding to the threads formed on the outer surface of the lift bar (212). In addition, the rotation guide (220) may be formed in a hollow shape so that the lift bar (212) can be accommodated on its inner surface. That is, the threads are formed at a point on the inner surface of the hollow portion.

[0071] According to one embodiment, at least one catch (221) may be formed on the outer surface of the rotation guide (220). For example, a plurality of catches (221) may be formed on the outer surface of the rotation guide (220), and the catches (221) of the rotation guide (220) may be formed vertically so as to be vertically fitted between a plurality of catch grooves (321) formed on the inner surface of the dial (320) described later.

[0072] Accordingly, the lower part of the rotation guide (220) is exposed to the lower part of the penetration part (130) of the container body (100) and is combined with the dial (320), but when the rotation guide (220) and the dial (320) are vertically combined, no interference occurs between the catch projection (221) and the catch groove (321), so that not only is the combination easy, but also separation is possible. Therefore, when the container body (100) and the lower actuator (300) are combined, the rotation guide (220) and the dial (320) are rotated as one unit to serve as a structure of an actuator that ejects the contents (A) inside the container body (100), and when the container body (100) and the lower actuator (300) are separated, a structure can be achieved in which separation is easily possible without mutual interference.

[0073] According to one embodiment, a hollow through-injection hole (230) may be formed in the lifting body (210) and the rotation guide (220). For example, a hollow through-injection hole (230) with a central portion completely penetrated from top to bottom may be formed in the lifting body (210) and the rotation guide (220).

[0074] Through this through-hole injection hole (230), backfilling using the inner space of the container body (100) becomes possible.

[0075] In addition, after the backfilling through the through-injection hole (230) is completed, the refill cap (331) is coupled to the through-injection hole (230) to seal the through-injection hole (230).

[0076] Figure 6 is an enlarged perspective view showing the joint portion of the container body and the lower drive body according to an embodiment of the present invention.

[0077] Referring to FIG. 6, according to one embodiment, a lower drive body (300) may be coupled to the lower portion of the container body (100).

[0078] The lower drive body (300) is coupled to the lower part of the container body (100) and is coupled to the lower part (specifically, the rotation guide) of the lifting member (200) to rotate the lifting member (200).

[0079] According to one embodiment, the lower drive body (300) may include a lower body (310) coupled to the lower portion of the container body (100).

[0080] According to one embodiment, the lower body (310) may include a dial receiving space in which a dial (320) is received inside and a container receiving space in which the lower part of the container body (100) is received. For example, the interior of the lower body (310) is formed hollow to receive the dial (320), and when the container body (100) and the lower actuator (300) are coupled, the lower part of the container body (100) is received into the interior of the lower body (310), and at the same time, the lower part of the rotation guide (220) received in the container body (100) is coupled with the dial (320) received inside the lower body (310), so that a complete stick-shaped container (1000) can be formed.

[0081] According to one embodiment, an opening (314) may be formed on the side of the lower body (310). For example, both sides of the lower body (310) may be formed in a form in which they are cut open, so that a portion of the dial (320) accommodated inside the lower body (310) is exposed to the outside through the opening (314).

[0082] In this way, by the user hand-holding and rotating a portion of the dial (320) exposed to the outside through the opening (314), the lifting member (200) (specifically, the rotation guide) coupled with the dial (320) is driven, thereby causing the contents (A) to rise to the upper portion of the container body (100).

[0083] According to one embodiment, the dial (320) can be assembled by inserting it through the opening (314) of the lower body (310). For example, the dial (320) can be assembled through the front of the container and then the container body (100) can be joined by inserting it in the vertical direction.

[0084] According to one embodiment, the lower body (310) may include a coupling groove (311) to which the coupling protrusion (110) of the container body (100) is coupled. The coupling groove (311) may be formed at a point (e.g., a side wall) on the inner surface of the lower body (310), but is not limited to a formation location. The coupling groove (311) may be formed inwardly in the shape of a groove at a point of the lower body (310), and may be formed in a shape corresponding to the shape of the coupling protrusion (110) of the container body (100) described above. Accordingly, the coupling protrusion (110) of the container body (100) may be accommodated so that the container body (100) and the lower actuator (300) (specifically, the lower body) may be coupled. These joining grooves (311) can be formed in the same number as the number of joining protrusions (110) formed in the container body (100).

[0085] According to one embodiment, the lower body (310) may include a detachment protrusion (312) formed to correspond to the detachment protrusion (120) of the container body (100). For example, the detachment protrusion (312) may be formed on both upper sides of the inner surface of the lower body (310).

[0086] These detachment protrusions (312) can be formed at positions corresponding to the positions where the detachment protrusions (120) formed on the aforementioned container body (100) are formed. That is, the detachment protrusions (312) formed on the lower body (310) and the detachment protrusions (120) formed on the container body (100) are formed at positions where they come into contact with each other when the container body (100) and the lower actuator (300) are combined.

[0087] Accordingly, in order to separate the container body (100) and the lower actuator (300), when the user presses the detachment press mark (313) formed on both sides of the lower body (310) described below, separation of the container body (100) and the lower actuator (300) can be induced by interference between the detachment protrusion (120) formed on the container body (100) and the detachment protrusion (312) formed on the lower actuator (300).

[0088] According to one embodiment, the detachable protrusion (312) may be formed to have a certain slope so as to easily push away the detachable protrusion (120) formed on the container body (100) as described above. At this time, the slope of the detachable protrusion (120) of the container body (100) and the slope of the detachable protrusion (312) of the lower body (310) are formed to correspond to each other so that when the detachable protrusions (120, 312) come into contact with each other, they are formed to be in close contact without being separated from each other, and when the container body (100) and the lower actuator (300) are separated by container elasticity, they can push away from each other.

[0089] According to one embodiment, the lower body (310) may have a detachment press mark (313) formed on the outer surface where the detachment protrusion (312) is formed. For example, the detachment press mark (313) may be formed at each of two points on the outer surface of the lower body (310).

[0090] This detachment press mark (313) can indicate the part where the detachment projection (120) of the container body (100) and the detachment projection (312) of the lower body (310) come into contact. In other words, it is a mark indicating a separation position where the container body (100) and the lower drive body (300) can be separated by the user pressing the detachment press mark (313).

[0091] According to one embodiment, the lower body (310) can accommodate a dial (320). The dial (320) is fitted into the interior of the lower body (310) through the opening (314) of the lower body (310) so that when the lower drive body (300) is coupled with the container body (100), it can be coupled with the lower portion of the rotation guide (220) exposed to the lower portion of the through portion (130) of the container body (100).

[0092] In this case, the dial (320) is coupled with the lower portion of the rotation guide (220), so that when the user rotates the dial (320) in one direction or the other direction, the rotation guide (220) coupled with the dial (320) rotates, thereby causing the lifting member (200) to rise and fall, thereby allowing the contents (A) to rise to the upper portion of the container body (100).

[0093] According to one embodiment, at least one engaging groove (321) may be formed on the inner surface of the dial (320). For example, the inner surface of the dial (320) may be partially cut vertically to form a plurality of protrusions to form a plurality of engaging grooves (321).

[0094] Between these plurality of catch grooves (321), the catch projections (221) of the aforementioned rotary guide (220) are vertically inserted to form a connection between the dial (320) and the rotary guide (220), and when the dial (320) rotates, the rotary guide (220) can be rotated integrally with the dial (320) by the catch projections (221) coupled to the catch grooves (321).

[0095] FIG. 7 is another perspective view illustrating the lower portion of a refillable stick-shaped container (1000) according to an embodiment of the present invention.

[0096] Referring to FIG. 7, according to one embodiment, the lower drive body (300) may further include a lower cap (330) detachably coupled to the lower portion of the lower body (310).

[0097] The lower cap (330) can be coupled to the lower part of the lower body (310). For example, the lower part of the lower body (310) can be detachably coupled with the lower cap (330) so that it can be opened when backfilling. Therefore, when initially manufacturing the stick-type container (1000), the lower part of the lower body (310) is formed to be open in order to perform backfilling using the internal space of the container body (100), and when the contents (A) are filled into the interior of the container body (100) through the through-injection hole (230) of the lifting member (200), and the lower part of the lower body (310) can be sealed by coupling the lower cap (330) when the filling is completed.

[0098] According to one embodiment, the refill cap (331) may be provided in the central portion of the lower cap (330). That is, the refill cap (331) is received and coupled to the inside of the through-injection hole (230), and is formed so that its lower portion is coupled to the central portion of the lower cap (330), so that when the lower cap (330) is detached from the lower body (310), the refill cap (331) is also separated from the through-injection hole (230), thereby opening the through-injection hole (230).

[0099] When the lower cap (330) is joined to the lower part of the lower body (310) after the backfilling is completed, a part of the refill cap (331) is accommodated and joined inside the through-injection hole (230), thereby sealing the through-injection hole (230).

[0100] According to one embodiment, all components of the aforementioned stick-shaped container (1000) may be formed of a single series of materials. For example, it may be formed of a plastic material, and specifically, it may be formed of a material such as a polyethylene series, a polypropylene series, PET, PE, PP, PCR, PETG, etc. However, it is not limited thereto, and any material may be applied as long as it forms the shape of the stick-shaped container (1000) and does not cause deterioration of the contents (A). Therefore, the container can be recycled as a whole without having to separate and discard parts, which has the advantages of being easy to recycle and being environmentally friendly.

[0101] Figure 8 is a cross-sectional view illustrating a refill container according to an embodiment of the present invention.

[0102] Referring to FIG. 8, according to one embodiment, a refill container (600) may include a container body (610) that accommodates contents (A) therein and guides the contents (A) to be raised and lowered inside, an elevating member (620) accommodated inside the container body (610) and that elevates the contents (A), and a refill container cap (630) that is coupled to the upper portion of the container body (610).

[0103] According to one embodiment, the container body (610) and the lifting member (620) of the refill container (600) can be formed to have the same configuration and joint structure as the container body (100) and the lifting member (200) described above.

[0104] According to one embodiment, the refill container cap (630) may include an inner sealing portion (631) that is formed to adhere to the inner surface of the container body (610) but has a certain curvature in the inward direction to prevent the contents (A) from leaking out during the filling process of the contents (A) using the back-filling method using the inner space of the container body (610), and an outer sealing portion (632) that is formed by being bent from the inner sealing portion toward the outer surface of the container body (610) but is formed to adhere so as to surround a portion of the outer surface of the container body (610), thereby preventing the contents (A) filled inside the container body (610) from leaking out again. The inner sealing portion (631) and the outer sealing portion (632) may each be formed as a pair, but are not limited thereto.

[0105] Figure 9 is a perspective view sequentially illustrating a refilling process of a refillable stick-type container according to an embodiment of the present invention.

[0106] Referring to FIG. 9, according to one embodiment, the user presses the release press mark (313) formed on both sides of the lower body (310) of the stick-shaped container (1000) when the use of the contents (A) is complete.

[0107] When the user presses the position where the release press mark (313) of the lower drive body (300) is formed, the release protrusion (120) of the container body (100) and the release protrusion (312) of the lower body (310) push each other, and the elasticity of the container due to the user's press causes the coupling protrusion (110) to detach from the coupling groove (311), so that the container body (100) and the lower drive body (300) are separated vertically.

[0108] In this way, after the container body (100) separated from the lower drive body (300) is completely separated from the lower drive body (300), a new refill container (600) filled with contents (A) is fitted and connected to the lower drive body (300).

[0109] At this time, it is desirable to adjust the positions of the rotation guide (220) and the dial (320) so that the rotation guide (220) exposed at the lower part of the through-hole (130) of the container body (100) of the refill container (600) is coupled with the dial (320) of the lower drive body (300).

[0110] Afterwards, the new refill container (600) is completely pressed downwards, and the connecting protrusion formed on the container body (610) of the refill container (600) is fitted into the connecting groove (311) formed on the lower body (310) of the lower actuator (300), thereby connecting the container body (610) of the refill container (600) and the lower actuator (300), thereby completing the refilling of the stick-type container (1000).

[0111] In this way, the stick-type container (1000) of the present invention can be refilled by separating the container body (100) in which the contents (A) have been completely used from the lower actuator (300) and then attaching a new refill container (600) to the lower actuator (300).

While specific terminology has been used herein, it is solely for the purpose of describing the present invention and is not intended to limit the scope of the invention as defined in the claims. Therefore, those skilled in the art will understand that various modifications and equivalent embodiments are possible. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
