Description

[Technical field]

[0001] The present invention relates to a dropper cap. [Background technology]

[0002] As a method for using liquid contents, for which it is important to use a small amount at a time and accurately measure the amount, there is a method in which the amount to be used each time is individually packaged in the form of a capsule, etc. However, such an individually packaged method has the problem that a relatively large amount of the contents remains in the capsule after the user has used it, making it very inefficient.

[0003] In order to overcome the problems of the individual packaging method, a method has been devised in which the contents are stored in a container, and then the contents are sucked up and then discharged using a dropper-structured drawing means. For example, a dropper cap structure has been devised in which the dropper is attached to the stopper of the container, so that the dropper can be attached to and detached from the container together with the stopper.

[0004] In such a dropper cap, a double structure of an inner cap and an outer cap may be adopted in order to protect the dropper more safely and improve heat resistance, airtightness, etc. However, when such a double structure is applied, a chemical substance such as an adhesive is added to bond the outer cap to the inner cap, which causes a safety problem. In addition, when the outer cap and the inner cap are made of different materials, it is not easy to separate them for disposal, which causes a problem of difficulty in meeting recycling standards. Summary of the Invention [Problem to be solved by the invention]

[0005] An object of the present invention is to provide a dropper cap that solves the above problems.

[0006] The technical problems of the present invention are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the following description. [Means for solving the problem]

[0007] According to an embodiment of the present invention, there is provided a dropper cap that is detachably attached to a container part that contains a content and that aspirates and dispenses the content. The dropper cap includes an inner cap that is detachably attached to the container part and an outer cap that is coupled to surround at least a portion of the inner cap, and the inner cap and the outer cap may be made of a metal material. Effect of the Invention

[0008] According to the present invention, since the inner cap and the outer cap are formed of the same metal material, the inner cap and the outer cap can be separately discharged as a unit and disposed of or recycled.

[0009] Furthermore, according to the present invention, the outer cap and the inner cap can be stably joined together without using any chemical substances such as adhesives.

[0010] Furthermore, according to the present invention, both the inner cap and the outer cap are made of a metal material, so that the inner cap and the outer cap can be joined together without any undercut.

[0011] Furthermore, according to the present invention, the inner cap and the outer cap can be stably fastened and joined without deformation of their shapes during the process of attaching and detaching them from the container portion or during the process of assembling the inner cap and the outer cap.

[0026] FIG. 1 is a perspective view of a dropper cap according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of the dropper cap according to the embodiment of the present invention, and FIG. 3 is a cross-sectional view of the dropper cap according to the embodiment of the present invention.

[0027] 1 to 3, the dropper cap 1000 may include an inner cap 100, an outer cap 200, and a dropper part 300. Here, the dropper cap 1000 may be attached to and detached from a container part in which contents are stored, and may suck up and discharge the contents.

[0028] The inner cap 100 is detachable from the container part. The inner cap 100 can be connected to the dropper part 300 on the inside and to the outer cap 200 on the outside. The inner cap 100 is attached to and detached from the container part while supporting the dropper part 300, thereby indirectly connecting or disconnecting the dropper part 300 to the container part.

[0029] In the embodiment, the inner cap 100 may be made of a metal material. Specifically, the material of the inner cap 100 may be aluminum (Al), but is not limited thereto, and may be selected from materials made of any one of iron (Fe), stainless steel (SUS), aluminum (Al), magnesium (Mg), and copper (Cu), or from materials made of an alloy containing at least one of these materials.

[0030] In the embodiment, at least one screw thread 110 may be formed on the inner circumferential surface of the inner cap 100. The screw thread 110 may be formed by bending at least a portion of the inner cap 100 inward. The inner cap 100 may be attached to and detached from the container part via the screw thread 110. However, this is merely an example, and the inner circumferential surface of the inner cap 100 may have various configurations other than the screw thread 110 to realize a detachable engagement such as a fitting protrusion.

[0031] In an embodiment, the inner cap 100 may have a thickness of 0.48 mm or more, specifically 0.48 to 0.52 mm, and more specifically 0.5 mm. If the thickness of the inner cap 100 is less than 0.48 mm, the shape of the thread 110 may be deformed, and the cap may not be firmly fastened to the container, resulting in a phenomenon of free spinning.

[0032] The outer cap 200 can be detachably coupled to the inner cap 100 while surrounding at least a portion of the inner cap 100. Since the outer cap 200 is coupled to the inner cap 100 so as to surround it, the structure of the inner cap 100 is not exposed to the outside, so that a simple impression can be created and the inner cap 100 can be protected from external impact.

[0033] In the embodiment, the outer cap 200 may be made of a metal material. Specifically, the material of the outer cap 200 may be aluminum (Al), but is not limited thereto, and may be selected from a variety of metal materials, such as one of iron (Fe), stainless steel (SUS), aluminum (Al), magnesium (Mg), and copper (Cu), or an alloy material containing at least one of these materials.

[0034] In this way, by forming the inner cap 100 and the outer cap 200 from a metal material, the inner cap 100 and the outer cap 200 can be disposed of or recycled as a single unit by simply separating the dropper portion 300 from the inner cap 100 and the outer cap 200. In addition, by forming both the inner cap and the outer cap from a metal material, the inner cap and the outer cap can be joined together without using an adhesive and without undercuts.

[0035] In an embodiment, at least one adhesion protrusion 210 may be formed on the inner peripheral surface of the outer cap 200. The adhesion protrusion 210 may be adhered to the outer peripheral surface of the inner cap 100. The adhesion allows the outer cap 200 and the inner cap 100 to be coupled to each other so as to be synchronously rotatable. As a result, the outer cap 200 and the inner cap 100 can be coupled to each other via the adhesion protrusion 210 without using chemical substances such as adhesives.

[0036] In an embodiment, the outer cap 200 may have a thickness of 0.43 mm or more, specifically 0.43 to 0.47 mm, and more specifically 0.45 mm. If the thickness of the outer cap 200 is less than 0.43 mm, the outer cap 200 may not have sufficient rigidity and may be deformed when coupled to the inner cap 100. Even if the outer cap 200 is coupled to the inner cap 100, the coupling may not be stably maintained and may be released.

[0037] The dropper portion 300 may be formed to extend a predetermined length through the inner cap 100 and the outer cap 200. By extending the predetermined length, the dropper portion 300 may be formed to extend inside the container portion when the dropper cap 1000 is coupled to the container portion.

[0038] In an embodiment, the dropper portion 300 may include a suction tube 310 and a pressing portion 320 .

[0039] The suction tube 310 can be formed to extend a predetermined length while penetrating in the longitudinal direction. By penetrating in the longitudinal direction in this manner, a suction space can be formed inside the suction tube 310. The contents can be sucked into the suction space according to the change in the internal pressure of the suction space, and can be discharged out of the suction space.

[0040] The pressing part 320 is coupled to the upper end of the suction tube 310, and the volume of the pressing part 320 changes when pressed, thereby inducing the suction and discharge of the contents. Specifically, when the pressing part 320 is pressed, the volume of the pressing part 320 decreases, and the internal pressure of the suction tube 310 increases. When the pressing part 320 is then released, the volume of the pressing part 320 increases, and the internal pressure of the suction tube 310 decreases. When the pressing part 320 is pressed while the suction tube 310 is inserted inside the container part, and the pressing part 320 is then released, the contents are sucked into the suction space in response to the decrease in the internal pressure of the suction tube 310. When the dropper cap 1000 is then separated from the container part and the pressing part 320 is pressed, the contents in the suction space are discharged to the outside in response to the increase in the internal pressure of the suction tube 310.

[0041] In the embodiment, at least one wing portion 321, 322 may be formed on the outside of the pressing portion 320. For example, a first wing portion 321 (lower) and a second wing portion 322 (upper) may be provided protruding from the outside of the pressing portion 320 at a distance from each other. In this case, at least one of the inner cap 100 and the outer cap 200 may be inserted between the first wing portion 321 and the second wing portion 322. This allows the pressing portion 320 (and the dropper portion 300) to be fixed to at least one of the inner cap 100 and the outer cap 200. For example, referring to FIG. 3, an end portion of the inner cap 100 may be inserted between the first wing portion 321 and the second wing portion 322 and in close contact with each other, thereby allowing the pressing portion 320 to be fixed to the inner cap 100. However, this is not limited to this, and various embodiments can be applied, such as the ends of the inner cap 100 and the outer cap 200 being inserted between the first wing portion 321 and the second wing portion 322 and being in close contact with each other, thereby fixing the pressing portion 320 to the inner cap 100 and the outer cap 200.

[0042] In the embodiment, a space s is formed between the upper end of the inner cap 100 and the upper end of the outer cap 200, and the first wing 321 can be disposed in the space s. In this case, the second wing 322 is pushed up by at least one of the inner cap 100 and the outer cap 200 inserted between the first wing 321 and the second wing 322, which can prevent problems such as a gap being generated or the appearance of the dropper cap 1000 being damaged.

[0043] The dropper cap 1000 shown in FIGS. 1 to 3 is merely an example, and various configurations may be applied depending on the embodiment to which the present invention is applied.

[0044] FIG. 4 is a cross-sectional view of a dropper cap according to an embodiment of the present invention, and FIG. 5 is a perspective view of an outer cap according to an embodiment of the present invention.

[0045] 4 and 5, the dropper cap 1000' may include an inner cap 100, an outer cap 200, and a dropper portion 300, and the inner cap 100, the outer cap 200, and the dropper portion 300 may be described in the same manner as the dropper cap 1000 of FIGS. 1 to 3.

[0046] In an embodiment, the outer cap 200 may have at least a portion of the lower end folded inward, and the inner cap 100 may be inserted inside the folded outer cap 200. The inner cap 100 may be fixed to the outer cap 200 by the insertion.

[0047] In an embodiment, the inner cap 100 may include a bonding region 120 and an insert region 130. The bonding region 120 may be detachably coupled to the container portion, and the insert region 130 may be provided at a lower end of the bonding region 120 and inserted into the inside of the folded outer cap 200. For example, the screw thread 110 may be formed by bending at least a portion of the bonding region 120 inward.

[0048] In an embodiment, the thickness of the insertion region 130 may be formed to be thinner than the thickness of the joining region 120. As a result, even if the insertion region 130 is inserted inside the folded outer cap 200, the inner circumferential surface of the outer cap 200 and the inner circumferential surface of the joining region 120 can be smoothly connected to each other.

[0049] In an embodiment, the outer cap 200 can include a shielding region 220 and a folding region 230. The shielding region 220 can be provided to surround at least a portion of the outer circumferential surface of the inner cap 100, and the folding region 230 can be provided at a lower end of the shielding region 220 and can be folded.

[0050] In an embodiment, the thickness of the folding region 230 may be formed to be thinner than the thickness of the shielding region 220. By forming the thickness of the folding region 230 to be relatively thin, folding of the folding region 230 may be performed more easily.

[0051] In an embodiment, the inner peripheral surface of the insertion region 130 may be in close contact with the folding region 230. The close contact between the insertion region 130 and the folding region 230 may improve the bonding strength between the inner cap 100 and the outer cap 200.

[0052] The dropper cap 1000' shown in FIGS. 4 and 5 is merely an example, and various configurations may be applied depending on the embodiment to which the present invention is applied.

[0053] FIG. 6 is a view illustrating an assembly process of the dropper cap according to the embodiment of the present invention.

[0054] 6, first, the inner cap 100 can be inserted into the outer cap 200 in a state where the folding region 230 is not folded. After the inner cap 100 is completely inserted, the folding region 230 can be folded and the insertion region 130 can be inserted and fixed inside the outer cap 200. To facilitate such folding, the thickness of the folding region 230 can be formed to be thinner than the thickness of the shielding region 220.

[0055] The assembly process of the dropper cap 1000' shown in FIG. 6 is merely an example, and various methods may be applied depending on the embodiment to which the present invention is applied.
