Description

[Technical Field]

[0001] The present invention relates to a solid drug container, and more particularly to a refillable solid drug container that can be refilled with a solid drug. [Background technology]

[0002] Generally, cosmetics are used in a variety of types and materials, such as solid, liquid, gel, and powder, and the cosmetic containers used to store them are also widely used in various forms. Among them, lipstick, lip gloss, eyeliner, etc. are produced in long cylindrical or pencil-shaped containers.

[0003] Such pencil-shaped containers are typically configured such that a solid stick-shaped cosmetic product is attached to a member that can be raised and lowered, and the cosmetic product moves up and down inside and outside the container by rotating a portion of the container.

[0004] However, most pencil-shaped cosmetic containers currently on the market typically have a diameter of 1 cm or more, and the diameter of the solid cosmetics is correspondingly large. If the diameter of the solid cosmetics is small or if it is in a thin stick shape, there is a problem that the solid cosmetics may break during use. Furthermore, if the diameter of the cosmetic container is small, there is a problem that it is difficult to design a lifting structure inside the container or to assemble it.

[0014] The above and other objects, features, and advantages of the present invention will be easily understood from the following preferred embodiments in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. The embodiments described below are exemplary embodiments provided to fully convey the concept of the present invention to those skilled in the art.

[0015] In this specification, when a component is said to be connected (or fastened or coupled) to another component, this may mean that the two components are directly connected (or fastened or coupled) or indirectly connected (or fastened or coupled). Also, in the drawings, the length and thickness of the components are exaggerated for the purpose of effectively explaining the technical content.

[0016] In this specification, the singular includes the plural unless otherwise specified. The expressions "comprise", "consist of", and "consist of" used in this specification do not exclude the presence or addition of one or more other elements in addition to the elements mentioned in this expression.

[0017] The present invention will be described in detail below with reference to the drawings. In describing the following embodiments, various specific details are described to facilitate detailed explanation and understanding of the invention, but the present invention is not limited thereto, and the technical concept of the present invention may extend to other specific configurations. Furthermore, in describing the present invention, it should be noted in advance that well-known aspects that are not closely related to the present invention will not be described to avoid confusion in describing the present invention.

[0018] Fig. 1 is a perspective view of a refillable solid drug container according to one embodiment of the present invention, Fig. 2 is a cross-sectional view of the refillable solid drug container, and Fig. 3 is an exploded perspective view of the refillable solid drug container. Fig. 4 is a perspective view showing a main body 10 and a guide ring 50 of the container according to one embodiment, and Figs. 5 and 6 are views showing a sliding member 40 and an adjustment part 30 according to one embodiment.

[0019] First, referring to FIG. 1, a refillable solid container (hereinafter simply referred to as a "container") according to one embodiment includes a main body 10 and a detachable cap 20, and an adjustment part 30 is rotatably connected to the lower end of the main body 10.

[0020] The cap 20 is detachably attached to the top of the main body 10. Hereinafter, when describing the positional relationship between components, unless otherwise distinguished, the terms "top," "upper end," or "front" refer to the direction in which the cap 20 is attached relative to the main body 10, and the terms "bottom," "lower end," or "rear" refer to the direction in which the adjustment unit 30 is attached. Furthermore, for example, "rising" or "advancing" of the cartridge 60 means moving forward relative to the main body 10, and "descending" or "rearward" means moving backward relative to the main body 10.

[0021] A cartridge 60 containing a solid agent 61 is inserted inside the main body 10, and when a user wishes to use the solid agent 61, as shown in Fig. 1(b), the user separates the cap 20 from the main body 10 and then turns the adjusting part 30 to protrude the solid agent 61 upward in the main body, and then the solid agent 61 can be used. In this case, the solid agent 61 may be, for example, a solid cosmetic product (e.g., lipstick, eyeliner, etc.) or a writing implement (e.g., crayon, pastel crayons, highlighter, etc.), but is not limited thereto, and may be any solid substance.

[0022] 2 and 3, a refillable solid drug container according to one embodiment may include a cylindrical body 10, a cap 20 detachably attached to an upper part of the body 10, an adjusting part 30 rotatably coupled to a lower part of the body 10, and a sliding member 40 and a cartridge 60 disposed inside the body 10.

[0023] The body 10 is a cylindrical member having a through-hole formed from the top to the bottom. In one embodiment, the body 10 is made of a plastic material and can be manufactured using a mold injection method. Preferably, the body 10 can be produced by manufacturing materials of different colors using a double injection method. For example, as shown in FIG. 2, the body 10 can be composed of an inner member 11 and an outer member 12 of different colors. In this case, the inner member 11 can be injected from a first cavity of a mold device and then transferred to a second cavity, where the outer member 12 can be injected on top of the inner member 11 to manufacture the body 10.

[0024] The internal space of the main body 10, i.e., the internal space that penetrates from the upper end to the lower end of the main body 10, can be divided into at least two internal spaces with different diameters. As shown in Figures 2 and 4, a first internal space having a predetermined first diameter is formed from the upper end to approximately the middle of the main body 10, and a second internal space having a second diameter larger than the first diameter is formed from the end of the first internal space to the lower end, and a step portion 15 is formed in the boundary region where the first internal space and the second internal space face each other due to the difference in diameter.

[0025] A guide ring 50 can be disposed in this step portion 15. That is, the outer diameter of the guide ring 50 is the same as the second diameter, and therefore the guide ring 50 can be inserted from the lower end of the main body 10 and coupled to the step portion 15. The guide ring 50 is a ring-shaped member having a through hole formed in its center, and the outer diameter is the same as the second diameter, and it is preferable that the cross-sectional shape of the central through hole be the same as the cross-sectional shape of the thread forming portion 41 of the sliding member 40, which will be described later.

[0026] 4, in one embodiment, anti-rotation protrusions 15b may be formed on stepped portion 15. That is, region 15a of stepped portion 15 where anti-rotation protrusions 15b are not formed has a second diameter, and the diameter of the portion where anti-rotation protrusions 15b are formed may be smaller than the second diameter and the same as or larger than the first diameter.

[0027] 4, a region 50a of the outer periphery of the guide ring 50, which has a relatively large diameter, has a second diameter and is coupled to a region 15a of the stepped portion 15 of the main body 10 that does not have the anti-rotation protrusions 15b, and a region 50b of the outer periphery of the guide ring 50, which has a relatively small diameter, is configured to come into contact with the anti-rotation protrusions 15b of the main body 10. As a result, when the guide ring 50 is coupled to the stepped portion 15 of the main body 10, the guide ring 50 can be fixed without rotating.

[0028] 2 and 3 again, the cap 20 is a member that is detachably fastened to the upper end of the main body 10. In one embodiment, the cap 20 may also be manufactured using a plastic material by a double injection molding method. For example, the cap 20 may be made of an inner member 21 and an outer member 22 of different colors and may be manufactured at the same time by a double injection molding method. An inner cap 25 may be further attached to the inside of the cap to seal the interior space of the main body 10 from the outside.

[0029] The adjustment part 30 is a member for adjusting the elevation of the sliding member 40, and is rotatably coupled to the lower end of the main body 10. In one embodiment, the adjustment part 30 may include a receiving tube 31 having a relatively small diameter and capable of receiving a portion of the sliding member 40, and a handle 32 having a relatively large diameter and protruding downward from the lower end of the main body 10.

[0030] The receiving tube 31 is a cylindrical member with an open upper end so as to partially receive the sliding member 40, and its outer diameter may be approximately the same as the second diameter of the main body 10. The receiving tube 31 and the handle 32 may be integrally formed, or may be manufactured separately and then coupled together. A groove 37 is formed along the outer circumferential surface near the lower end of the receiving tube 31, and a protrusion (17 in FIG. 4) is formed on the inner diameter side of the main body 10 corresponding to the groove 37. Therefore, by inserting the adjusting part 30 into the main body 10 from below and fitting the protrusion 17 into the groove 37, the adjusting part 30 can be rotatably fastened to the main body 10 without coming off.

[0031] The sliding member 40 is disposed in the interior space of the main body 10, is threadedly coupled to the adjusting part 30, and moves up and down as the adjusting part 30 rotates. In one embodiment, the sliding member 40 includes a thread-forming part 41 and a fastening part 42. The thread-forming part 41 is rod-shaped and has a thread formed on its outer periphery, and the fastening part 42 extends from the upper end of the thread-forming part 41 and has a receiving groove formed therein so that one end of the cartridge 60 can be detachably coupled thereto. The thread-forming part 41 is threadably inserted into the receiving tube 31 of the adjusting part 30, thereby fastening the sliding member 40 to the adjusting part 30.

[0032] The thread-forming portion 41 of the sliding member 40 has a cylindrical shape and has threads formed on its outer circumferential surface. However, in a preferred embodiment, the thread-forming portion 41 has flat portions 43 on its outer circumferential surface along its length that are not threaded. As shown in FIGS. 5 and 6(b), a pair of opposing flat portions 43 are formed as flat surfaces on the opposing outer circumferential surfaces of the thread-forming portion 41 that are not threaded along their length. On the other hand, as shown in FIG. 4, the inner circumferential surface of the guide ring 50 is formed to have the same cross-sectional shape as the thread-forming portion 41. In other words, it should be understood that the inner circumferential side of the guide ring 50 is composed of an area 51a that contacts the threads of the thread-forming portion 41 and an area 51b that contacts the flat portions 43.

[0033] The cartridge 60 may be composed of a solid agent 61 and a holder 62. The solid agent 61 may be a solid cosmetic such as lipstick, and its lower end is fitted and supported in the holder 62. An accommodation groove capable of accommodating the lower end of the solid agent 61 is formed in the upper part of the holder 62, and a protrusion that can be detachably fitted into the fastening part 42 of the sliding member 40 is formed in the lower part of the holder 62.

[0034] Hereinafter, the configurations of the adjustment part 30 and the sliding member 40 will be described in more detail with reference to FIGS.

[0035] In one embodiment, slots 35, 45 are formed in the receiving tube 31 of the adjusting portion 30 and the thread-forming portion 41 of the sliding member 40, respectively. As shown in Fig. 5, a slot 35 having a predetermined depth d1 is formed in the upper end of the receiving tube 31 of the adjusting portion 30, and a slot 45 having a predetermined length d2 is also formed in the lower end of the thread-forming portion 41 of the sliding member 40. The depth of each slot 35, 45 may vary depending on the specific embodiment, but may be, for example, between several millimeters and 1 centimeter.

[0036] The thread-forming portion 41 inserted into the housing tube 31 is threadedly fastened to the inner surface of the housing tube 31, and for this purpose, a thread 33 is formed over a predetermined length inside the housing tube 31. In this case, in a preferred embodiment, the thread 33 formed on the housing tube 31 is formed over a length d1 from the tip of the housing tube 31 to the length at which the slot 35 is formed, or is formed over a length shorter than this length d1. Therefore, when assembling the container, when the worker pushes the thread forming portion 41 into the accommodating tube 31, the presence of the slots 35, 45 allows the diameters of each end of the accommodating tube 31 and the thread forming portion 41 to vary slightly until the lower end of the thread forming portion 41 enters the accommodating tube 31 to the predetermined depth d1, so the thread forming portion can be easily inserted by simply pushing it into the accommodating tube.After that, the adjusting portion 30 is rotated relative to the sliding member 40, so that the thread forming portion 41 is further inserted into the inside of the accommodating tube 31.Therefore, the sliding member 40 and the adjusting portion 30 can be assembled easily and quickly when assembling the container.

[0037] Meanwhile, in a preferred embodiment, in order to prevent the sliding member 40 from slipping out of the adjusting part 30, the sliding member 40 may have a protrusion 46 that protrudes radially by a predetermined height from the lower end of the thread-forming part 41. The diameter of the tip of the thread-forming part 41 where the protrusion 46 is formed may be larger than the maximum diameter of the threads of the thread-forming part 41 and may be the same as or smaller than the inner diameter of the region of the receiving tube 31 where the threads 33 are not formed. Alternatively, considering that the diameter of the end of the thread-forming part 41 is slightly reduced due to the presence of the slot 45, the diameter of the end of the thread-forming part 41 where the protrusion 46 is formed may be slightly larger than the inner diameter of the region of the receiving tube 31 where the threads 33 are not formed.

[0038] As described above, the container according to the present invention has the following advantages when assembling the container, using it, and replacing the cartridge.

[0039] First, when assembling the container, first insert the sliding member 40 into the internal space from the front of the main body 10, and then push the sliding member 40 from the front to the rear so that the end of the thread-forming portion 41 (i.e., the end where the slot 45 is formed) protrudes outside the rear end of the main body 10.

[0040] Thereafter, the guide ring 50 is fitted into the thread forming portion 41, and the thread forming portion 41 is fitted into the housing tube 31 of the adjusting part 30. At this time, since the guide ring 50 is a separate member from the main body 10, the sliding member 40 can be inserted and fitted into the main body 10 first, and then the guide ring 50 can be fitted into the thread forming portion 41, which simplifies and speeds up the work of matching the cross-sectional shapes of the guide ring 50 and the thread forming portion 41.

[0041] In addition, since the diameter of the end can be flexibly changed by the slots 35 and 45, the sliding member 40 can be easily inserted into the receiving tube 31, and once inserted, the protrusion 46 can prevent the sliding member 40 from slipping out of the adjusting part 30. After the thread forming portion 41 is partially inserted into the receiving tube 31 of the adjusting portion 30, the adjusting portion 30 is pushed toward the main body 10 to couple with it. That is, the protrusion 17 is fitted into the recess 37, and the adjusting portion 30 is rotatably coupled to the main body 10.

[0042] Then, the adjusting part 30 is rotated to advance the sliding member 40 until the fastening part 42 of the sliding member 40 protrudes from the top of the main body 10, and the cartridge 60 is coupled to the fastening part 42. After that, the adjusting part 30 is rotated in the opposite direction to retract the cartridge 60 into the main body 10, and the cap 20 is attached to complete the assembly.

[0043] Second, in relation to the use of the container, Figure 7 is a diagram illustrating the operation of a refillable solid drug container according to one embodiment, Figure 7(a) showing a state in which the cartridge 60 is fully retracted inside the main body 10, and Figure 7(b) is a cross-sectional view in which the adjustment part 30 is turned to move the cartridge 60 forward a certain length from the upper end of the main body 10. It should be understood that when the adjustment part 30 is turned, the relative movement of the thread 33 of the receiving tube 31 and the thread of the thread-forming part 41 of the sliding member 40 causes the sliding member 40 to move forward of the main body 10, and the solid drug 61 in the cartridge 60 protrudes from the main body 10.

[0044] At this time, in the container configuration of the present invention, while the adjusting part 30 is rotating, the flat part 43 of the thread forming part 41 of the sliding member 40 is engaged with the area 51b on the inner surface of the guide ring 50, so that the sliding member 40 only moves up and down without rotating. Therefore, the solid agent 61 can advance to the outside of the main body 10 or retract into the main body without rotating, allowing for convenient use of the solid agent.

[0045] Furthermore, if a protrusion 46 is provided on the end of the thread-forming portion 41, even if the user rotates the adjusting portion 30 to raise the sliding member 40 to its maximum position and then further rotates the adjusting portion 30, the protrusion 46 will catch on the thread 33, preventing the sliding member 40 from rising any further. That is, the existence of the slots 35, 45 allows the diameter of the end of the thread-forming portion 41 to decrease and the diameter of the end of the receiving tube 31 to increase within the allowable tolerances, so that the threads in the end region of the thread-forming portion 41 and the threads 33 of the receiving tube 31 can rotate freely without wearing against each other. At the same time, the protrusion 46 catches on the thread 33, preventing the sliding member 40 from rising, thereby preventing the sliding member 40 from coming off the adjusting portion 30.

[0046] Third, when replacing the cartridge 60, the adjusting part 30 is rotated to advance the cartridge 60 until the holder 62 of the cartridge 60 is exposed to the outside of the main body 10. Then, the holder 62 is pulled to separate the cartridge 60 from the fastening part 42, and the holder 62 of the new cartridge 60 is fitted into the fastening part 42, thereby easily replacing the cartridge.

[0047] As described above, those skilled in the art will appreciate that various modifications and variations can be made from the above description of the specification. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the following claims and their equivalents. [Explanation of symbols]
