Description

Technical Field

[0001] This invention relates to a one-touch cap with a sealing function and to an environmentally friendly one-touch cap with a sealing function, wherein the sealing function is improved while maintaining the convenience of the one-touch cap, and the one-touch cap is made of a single material so that no separate disposal is required. Background Technology

[0002] Generally speaking, cosmetic containers are used to store and use cosmetics for various purposes, and most cosmetic containers are equipped with airtight components to prevent deterioration or damage to cosmetics during dispensing, carrying, and storage, and the degree of airtightness varies depending on the purpose or nature of the cosmetic.

[0003] Therefore, for containers used to store and use relatively low-viscosity cosmetics (such as cream-type cosmetics) or similar types of cosmetics, a relatively high level of airtightness is not required. Taking these points into account, conventional cream-type cosmetic containers have a structure comprising a container body, an inner stopper, and a cap. A separate filler is attached to the inside of the cap to provide airtightness to the cosmetics contained in the container body, and the inner stopper simply serves as a cover to prevent the cosmetics contained in the container body from contacting the inner surface of the cap.

[0004] Recent trends have also encouraged the development of cosmetic containers that are designed with resource recycling and environmental considerations in mind, and that are environmentally friendly products that minimize inconvenience to consumers due to the use or disposal of the product by enabling easy individual disposal.

[0005] Taking these points into account, there are various problems with conventional structures in which individual fillers are attached to the inner surface of the cap to provide airtightness for cosmetics. Specifically, due to the material differences between cosmetic containers and other components, it is difficult to dispose of cosmetic containers separately, and additional manpower or costs are required for individual collection.

[0006] Therefore, it is necessary to address these issues.

[0007] The background technology of this invention is disclosed in Korean Utility Model Registration Publication No. 20-0270346 (registered on March 19, 2002: Utility Model Name: Cosmetic Box with One-Piece Lid). Summary of the Invention

[0043] refer to Figures 1 to 9According to one embodiment of the present invention, a one-touch cover 100 with sealing function includes a body 110, a cover 120 and an opening / closing operation part 130.

[0044] like Figure 9 As shown, the main body 110 can be formed in a ring shape and connected to the inlet of the upper part of the container C in which the contents are contained. That is, the main body 110 can be integrally formed with the inlet of the container C, or it can be fixed to the inlet by a separate connecting part. The container C can be a container of any shape in which the contents are contained, and has an inlet through which the contents can be removed.

[0045] refer to Figure 2 and Figure 7 The cover 120 is disposed on the body 110 to open or close the opening of the body 110 via a hinge, and includes an annular portion 122 rotatably disposed on the circumference of the body 110 and a rotating cover 124 hinged to the annular portion 122 to open or close the opening of the body 110.

[0046] That is, the ring portion 122 is formed into a ring shape with a predetermined width, and the rotating cover 124 is hinged to the ring portion 122 via the hinge portion 123.

[0047] Corresponding stepped portions 125 are formed on the facing surfaces of the ring portion 122 and the rotating cover 124. The stepped portions 125 can be formed to correspond to each other and have a wide contact area, thereby improving the sealing force and preventing the corresponding surfaces of the ring portion 122 and the rotating cover 124 from misaligning when the rotating cover 124 is closed.

[0048] A tapered portion 112 is formed on the upper end face of the main body 110. When the rotating cover 124 is opened or closed, the tapered portion 112 can prevent the inner surface of the rotating cover 124 from getting stuck on the upper end portion of the main body 110.

[0049] refer to Figures 3 to 5 The opening / closing operation section 130 can make the cover 120 in close contact with the body 110, so that the cover 120 and the body 110 are sealed, and the opening / closing of the cover 120 can be controlled.

[0050] In this configuration, the indicator 115 can be formed in the body 110 and the cover 120, and can be aligned with each other when the cover 120 is open, thereby allowing visual inspection of the open state (see [link]). Figure 1 ).

[0051] The opening / closing operation section 130 includes a sealing rib 132, a sealing operation section 140, and an opening / closing control section 150.

[0052] The sealing rib 132 is formed to protrude from the inner surface of the rotating cover 124. More specifically, as Figure 4 and Figure 5 As shown, the sealing rib 132 can be formed to protrude downward from the bottom surface of the rotating cover 124, and when the cover 120 is lowered by the sealing operation portion 140 described below, the sealing rib can contact the inner surface of the opening of the body 110 to seal the opening of the body 110.

[0053] A tapered portion 133 is formed at the end portion of the sealing rib 132 so as to be inserted into the opening of the body 110 when the rotating cover 124 is closed.

[0054] The sealing operation portion 140 moves the cover 120 downward so that the sealing rib 132 comes into close contact with the opening of the body 110, and may include sealing guide grooves 142 and sealing guide protrusions 144, each of the sealing guide grooves being formed to slope downward from the circumferential surface of the body 110 by a predetermined length, and the sealing guide protrusions being formed on the ring portion 122 to be inserted into the sealing guide groove 142 accordingly.

[0055] That is, the sealing rib 132 is lowered vertically by the rotation of the cover 120, and can therefore be inserted vertically into the opening of the body 110.

[0056] One end and the other end of the sealing guide groove 142 may have a horizontal difference, allowing the sealing rib 132 to be inserted into the opening of the body 110. Therefore, as... Figure 5 and Figure 8 As shown in Figure A, when the sealing guide protrusion 144 is positioned at the lower end of the sealing guide groove 142 due to the rotation of the cover 120, the sealing rib 132 is inserted into the opening of the body 110, thereby sealing the opening, and as... Figure 6 and Figure 8 As shown in Figure B, the opening is opened when the sealing guide protrusion 144 is positioned at the upper end of the sealing guide groove 142 by the rotation of the cover 120.

[0057] Preferably, three or more sealing guide grooves 142 are formed on the circumferential surface of the body 110 and are spaced apart from each other by a predetermined interval. When only two sealing guide grooves 142 are formed on the circumferential surface of the body 110, the cover 120 may rock to both sides relative to the sealing guide protrusion 144. Therefore, three sealing guide grooves 142 are provided at 120° intervals to prevent the cover 120 from rocking.

[0058] refer to Figure 3Position-fixing protrusions 143 are formed at each end portion of the sealing guide groove 142 to fix the position of the sealing guide protrusions 144. The current position of the sealing guide protrusions 144 that have passed the position-fixing protrusions 143 can be fixed to prevent unintended movement of the cover 120.

[0059] In addition, the user can feel the shaking of the sealing guide protrusion 144 as it passes over the position fixing protrusion 143, thereby identifying the sealing state of the cover 120 or the state in which the cover 124 can be opened by rotating it.

[0060] refer to Figure 2 and Figure 7 The opening / closing control section 150 can control the opening / closing of the rotating cover 124 by the sealing operation section 140 combined with the downward movement of the cover 120.

[0061] The open / close control section 150 includes: a plurality of control guide grooves 152, each of the plurality of control guide grooves having an inlet groove 153 and being formed to slope downward from the circumferential surface of the body 110 for a predetermined length; and a plurality of control guide protrusions 154 formed on the rotating cover 124 to be inserted into the control guide grooves 152.

[0062] Three or more control guide grooves 152 are formed on the circumferential surface of the body 110 and are spaced apart from each other by a predetermined interval. That is, similar to the sealing guide groove 142, the three control guide grooves 152 can be arranged at 120° intervals to prevent the rotating cover 124 from shaking.

[0063] The control guide groove 152 is formed parallel to the sealing guide groove 142, and the control guide protrusion 154 is formed collinearly with the sealing guide protrusion 144 and is formed above the sealing guide protrusion.

[0064] Therefore, the open / close control section 150 can control the opening / closing of the rotating cover 124, and can be used to guide the rotation of the cover 120 and seal the cover 120 together with the sealing operation section 140.

[0065] An inlet groove 153 is formed in the upper portion of the control guide groove 152, such that the control guide protrusion 154 disengages when the rotating cover 124 is opened. The inlet groove 153 is formed collinear with the corresponding position fixing protrusion 143 formed in the upper portion of the sealing guide groove 142 in the position fixing protrusion 143.

[0066] That is, when the sealing guide protrusion 144 is located on the position fixed protrusion 143 formed on the upper part, the control guide protrusion 154 can be positioned collinear with the inlet groove 153, so that the rotating cover 124 can be opened.

[0067] Furthermore, preferably, the lower portion of the control guide groove 152 (i.e., the portion opposite to where the inlet groove 153 is located) is formed to be slightly lower than the level of the control guide protrusion 154. Therefore, the control guide protrusion 154 is forcibly fitted into the lower portion of the control guide groove 152 to bring the body 110 and the rotating cover 124 into closer contact with each other, thereby improving the sealing force. In this embodiment, the level of the lower portion of the control guide groove 152 is illustrated as being lower than the level of the control guide protrusion 154, but the invention is not limited thereto. Various design changes are possible to forcibly fit the control guide protrusion 154 into the lower portion of the control guide groove 152. For example, various design changes can be made, such as forming the control guide protrusion 154 with a slightly larger diameter, or forming the lower end of the control guide groove 152 in a shape that slopes downwards more than horizontally.

[0068] The sealing guide groove 142 and the control guide groove 152 can be connected to each other through the connecting groove 160, and the sealing guide protrusion 144 inserted into the sealing guide groove 142 can be attached or detached through the inlet groove 153.

[0069] The connecting groove 160 can be a component for assembling or separating the cover 120, and the cover 120 can be assembled and separated by the inlet groove 153 of the control guide groove 152 and the connecting groove 160 connecting the control guide groove 152 and the sealing guide groove 142.

[0070] That is, the sealing guide protrusion 144 can be inserted through the inlet groove 153 and enter the sealing guide groove 142 through the connecting groove 160, thereby realizing assembly and disassembly.

[0071] The undercut portion 162 is formed in the connecting groove 160 to prevent the sealing guide protrusion 144 from accidentally disengaging from the sealing guide groove 142 into the connecting groove 160.

[0072] like Figure 3 As shown, the connecting groove 160 is formed to slope upward in the opposite direction to the sealing guide groove 142, and an inwardly protruding undercut 162 is formed at each lower edge of the connecting groove 160, thereby preventing the sealing guide protrusion 144 from entering the connecting groove 160 while moving along the sealing guide groove 142.

[0073] According to this embodiment, the body 110 and the cover 120 can be made of a single material. For example, the body 110 and the cover 120 can be made of a single material, polypropylene (PP). The fact that all the above components are made of a single material provides a product designed with resource recycling and environmental considerations in mind.

[0074] Meanwhile, as an example of modification to subject 110, such as Figure 10 As shown, a receiving space 170, in which the contents are contained, can be formed in the body 110. The body 110 can be formed to have a predetermined height, and its bottom surface can be formed to have a receiving space 170 capable of accommodating a predetermined amount. Therefore, the cover 120 can be connected so that the body 110 itself can be used as a container.

[0075] In addition, refer to Figures 11 to 13 As a modified example of hinge portion 223, ring portion 122 and rotating cover 124 are connected by hinge portion 223, and hinge portion 223 includes hinge shaft 224 formed on ring portion 122 and hinge bracket 225 formed on rotating cover 124 to be coupled to hinge shaft 224.

[0076] The hinge bracket 225 is configured to be attached to or detached from the hinge axis 224. That is, the hinge bracket 225 is configured to have a "C" shaped cross-section and is capable of being attached to or detached from the hinge axis 224.

[0077] The operation and effects of a one-touch sealing cap according to an embodiment of the present invention will be described below.

[0078] First, refer to Figure 3 and Figure 4 It describes the assembly of the body 110 and the cover 120, wherein the sealing guide groove 142 and the control guide groove 152 are formed on the upper and lower parts of the circumferential surface of the body 110 and are engraved in parallel with the same shape, and each sealing guide protrusion 144 and each control guide protrusion 154 inserted therein are respectively formed to be collinear with the ring portion 122 and the rotating cover 124.

[0079] After the sealing guide protrusion 144 formed on the ring portion 122 is aligned and inserted into the inlet groove 153 formed in the control guide groove 152, the sealing guide protrusion 144 enters the sealing guide groove 142 through the connecting groove 160. Subsequently, the control guide protrusion 154 also enters the control guide groove 152 through the inlet groove 153. Each sealing guide protrusion 144 and each control guide protrusion 154 is inserted into the corresponding sealing guide groove 142 and the corresponding control guide groove 152, thereby completing the assembly.

[0080] In the following text, reference will be made to Figures 5 to 8 Describe the closing and opening operations of cover 120.

[0081] refer to Figure 5 and Figure 8 A. When the sealing guide protrusion 144 and the control guide protrusion 154 are located at the lower end portion of each sealing guide groove 142 and the lower end portion of each control guide groove 152, the sealing rib 132 formed to protrude from the inner surface of the rotating cover 124 can come into close contact with the inner surface of the opening of the body 110 to seal the opening of the body 110, since the cover 120 is lowered from the body 110.

[0082] A positioning protrusion 143 may be formed at the lower end of the sealing guide groove 142 to fix the position of the sealing guide protrusion 144, thereby preventing unintended movement of the cover 120.

[0083] Furthermore, the lower end portion of the control guide groove 152 can be formed slightly smaller than the control guide protrusion 154, so that the control guide protrusion 154 can be forcibly fitted into the lower end portion of the control guide groove 152, thereby allowing the main body 110 and the rotating cover 124 to contact each other more tightly to improve the sealing force. In addition, the position fixing protrusion 143 and the interference fit between the control guide protrusion 154 and the control guide groove 152 can securely maintain the closed and sealed state of the main body 110 and the cover 120.

[0084] If the user wants to open cover 120, such as Figure 6 and Figure 8 As shown in Figure B, when the user rotates the cover 120 to one side, each sealing guide protrusion 144 and each control guide protrusion 154 moves along the corresponding sealing guide groove 142 and the corresponding control guide groove 152, and the cover 120 is lifted from the body 110.

[0085] The sealing guide protrusion 144 is fixed by a fixed protrusion 143 that passes over the upper part of the sealing guide groove 152, and the control guide protrusion 154 is aligned with the inlet groove 153 formed in the upper part of the control guide groove 142.

[0086] As the cover 120 is lifted, the contact between the sealing rib 132 formed in the rotating cover 124 and the inner surface of the opening can be released, allowing the opening to be opened, and the rotating cover 124 can ensure that there is space therein that can be opened or closed by a hinge.

[0087] Subsequently, refer to Figure 7 and Figure 8C. By rotating the rotating cover 124, the user can disengage the control guide protrusion 154 through the inlet groove 153, thereby opening the rotating cover 124 to access the contents of the container C.

[0088] When the contents are used up, the rotating cover 124 closes, and the cover 120 rotates in the opposite direction to the opening direction. Each sealing guide protrusion 144 and each control guide protrusion 154 moves along the corresponding sealing guide groove 142 and the corresponding control guide groove 152 to lower the cover 120, thereby resealing the container C and keeping the cover 120 locked.

[0089] Furthermore, a tapered portion 112 may be formed at the upper end of the body 110 to prevent interference between the inner surface of the rotating cover 124 and the upper end of the body 110 when the rotating cover 124 is opened or closed, thereby achieving a smooth opening / closing operation.

[0090] At the same time, such as Figure 10 As shown, the main body 110 can be formed to have a predetermined height, and the bottom surface can be formed to have a receiving space 170 capable of accommodating contents, so that the main body 110 itself can be used as a container.

[0091] In addition, refer to Figures 11 to 13 The hinge portion 223 may include a hinge shaft 224 and a hinge bracket 225 that are separable from each other, and thus can be applied to various containers such as large-capacity containers. The rotating cover 124 can be separated and used depending on the usage state, thereby improving usability.

[0092] As described above, the one-touch cap of the present invention has a structure in which the cover 120 rotates once relative to the body 110 to perform sealing and locking or opening and unlocking, thereby providing ease of use. Furthermore, the cover 120 can be vertically lowered by its rotation, allowing sealing to be achieved without the use of separate filler. Therefore, due to these structural features, there is an effect that allows products with sealing functions to be produced using a single material.

[0093] Furthermore, the sealing operation section 140 and the opening / closing control section 150 are arranged in a two-row structure to achieve stable movement, and the sealing position and opening position can be identified by the position fixing section, thereby providing ease of use.

[0094] Furthermore, the body 110 and the cover 120 are made of a single material, PP, thus providing a product designed with resource recycling and environmental considerations in mind. No separate disposal is required, thus providing an environmentally friendly product that minimizes inconvenience to consumers due to its use or disposal.

[0095] The invention has been described with reference to embodiments shown in the accompanying drawings, but these are merely illustrative and those skilled in the art will understand that various modifications and other equivalent embodiments are thus possible.
