MODE FOR CARRYING OUT THE INVENTION
[0022] Hereinafter, a container and a container cap in accordance with the present invention will be described with reference to the accompanying drawings.
[0023] As illustrated in FIGS. 1 to 12, the container cap in accordance with the present invention includes: a cap body 100 coupled to a container inlet 12 of a container 10 in which contents are contained; and an upper lid 200 coupled to the cap body 100 to cover an upper side of the cap body 100.
[0024] The container 10 that is a component in which a liquid material such as a beverage or a material in the form of powder is contained may include all sorts of components as long as the container inlet 12 for container discharge is formed therein.
[0025] The contents contained in the container 10 may be various materials such as a liquid material in which supplementary contents 42 that will be described later is drunk together with a solid pill depending on a combination with the supplementary contents. Typically, the contents may be made of a liquid material.
[0026] Also, the container 10 may have various shapes such as a cylindrical shape or a rectangular cylinder shape except for the container inlet 12,
[0027] Also, the container 10 may be made of a plastic material or glass. Here, the container cap may be made of a plastic material in consideration of manufacturing and fracture separation.
[0028] The container inlet 12 that is a discharge hole through which the contents are discharged to the outside and a portion opened and closed by opening and closing of the container cap 100 may have various structures according to a coupling structure of the container inlet 12.
[0029] The cap body 100 that is a component coupled to the container inlet 12 of the container 10 in which the contents are contained may have various configurations.
[0030] For example, the cap body 100 may include: an upper plate part 110 covering an opening of the container inlet 12; and a container coupling part 151 extending downward from the upper plate part 101 and coupled to the container inlet 12.
[0031] The upper plate part 101 that is a component for covering the opening of the container inlet 12 may have a circular plate shape.
[0032] Also, the upper plate part 101 is fractured to form an outlet plate 110 that forms a discharge hole 102 through which the contents contained in the container are discharged.
[0033] The outlet plate 110 that is a component fractured from the upper plate part 101 to form the discharge hole 102 through which the contents contained in the container are discharged may include all sorts of components as long as the components are fractured from the upper plate part 101 to form the discharge hole 102.
[0034] In particular, the outlet plate 110 may be partitioned by a cut line 131 formed on the upper plate part 101 so as to be easily broken from the upper plate part 101.
[0035] The cut line 131 may be formed as a recessed cut groove so that the outlet plate 110 is fractured from the upper plate part 101.
[0036] As illustrated in FIGS. 2 and 6a, the cut line 131 may form an open curve so that the outlet plate 110 is fractured from the upper plate part 101 in a state of being partially coupled with the upper plate part 101.
[0038] As illustrated in FIGS. 1, 2, 6b, 7a and 8, a hook part 132 may be formed on a bottom surface of the upper plate part 101 to maintain a folded state after the outlet plate 110 is pressed and folded by a pushing part 210.
[0039] The hook part 132 that is a component formed on the bottom surface of the upper plate part 101 to maintain the folded state after the outlet plate 110 is pressed and folded by a pushing part 210 may have various configurations.
[0040] For example, as illustrated in FIGS. 1, 2, 6b, 7a and 8, each of a pair of hook parts 132 may have a width less than a width W (diameter) of the outlet plate 110 to maintain the folded state after the outlet plate 110 is pressed and folded by a pushing part 210.
[0041] As illustrated in FIGS. 11 and 12, the outlet plate 110 and the hook part 132 may be configured in various embodiments in connection with a configuration of the pushing part 210 that will be described later.
[0042] For example, as illustrated in FIG 12a, the outlet plate 110 may be completely separated when fractured from the upper plate part 101 and integrally connected by a connection part 111 formed on the bottom surface of the upper plate part 101.
[0043] Here, the pushing part 210 may have a structure by which the outlet plate 110 is completely separated from the upper plate part 101.
[0044] For another example, as illustrated in FIG 12b, the outlet plate 110 may be fractured and separated from the upper plate part 101 in a state of being connected to a plurality of portions of the upper plate part 101.
[0045] That is, as illustrated in FIG 12b, the outlet plate 110 is separated into two members, and at this time, the outlet plate 110 may be connected to the upper plate part 101 at two points to maintain a connected state while being folded from the upper plate part 101.
[0046] In addition, the hook part 132 of the upper plate part 101 is provided in accordance with the number and position of the outlet plate 110 to be fractured and separated.
[0047] On the other hand, the outlet plate 110 may be formed of a circular plate having a size appropriate to form a concentric circle on the upper plate part 101 and be foldable in the container inlet 12.
[0049] Here, the outlet plate 110 may be disposed as close as possible to an edge of the upper plate part 101 in consideration that the contents are discharged to the outside through the discharge hole 102 fractured and separated from the upper plate part 101.
[0050] As illustrated in FIGS. 1 and 2, the upper plate part 101 may be inclined downward toward the outlet plate 110 so that the contents are easily discharged.
[0051] Also, supplementary contents such as grains and powder, which are mixed with the contents contained in the container 10, may be filled in a space between the upper plate part 101 and the upper lid 200 that will be described later.
[0052] The supplementary contents may be filled in the space between the upper plate part 101 and the upper lid 200 that will be described later, injected into the container 10 through the discharge hole 102 formed as the outlet plate 110 is fractured and separated, and then mixed with the contents.
[0053] The container coupling part 151 that is a component extending downward from the upper plate part 101 and coupled to the container inlet 12 may have various configurations according to the coupling structure of the container inlet 12.
[0054] For example, the container coupling part 151 may be screw-coupled to the container inlet 12, and a female screw part 153 that is screw-coupled with a male screw part 12a may be formed on an outer circumferential surface of the container inlet 12 may be formed on an inner circumferential surface of the container coupling part 151.
[0055] Also, the container coupling part 151 may be coupled with the container inlet 12 through a snap-type structure.
[0056] On the other hand, an upper partition part 152 protruding upward to be sealingly coupled when the upper lid 200 that will be described later is coupled may be additionally formed on the cap body 100.
[0057] Also, the cap body 100 may include a sealing unit for sealing the inside of the container 10 when coupled to the container inlet 12.
[0058] The sealing unit may be a gasket, a sealing member, etc., and as illustrated in FIGS. 1 and 2, a ring-shaped gasket 142 closely contacting the inner circumferential surface of the container inlet 12 to seal the container 10 may extend downward from the bottom surface of the upper plate part 101.
[0059] The upper lid 200 that is a component coupled to the cap body 100 in order to cover the upper side of the cap body 100 may have various configurations.
[0060] For example, the upper lid 200 may be coupled to the cap body 100 in a hinge-rotation method by a hinge coupling part 290 at one side based on a central line passing through a center thereof and integrally coupled, i.e., formed, with the cap body 100.
[0061] The hinge coupling part 290 that is a component connecting the upper lid 200 to the cap body 100 in the hinge-rotation method at one side based on the central line passing through the center may have various shapes such as a thin film or band.
[0062] Here, the upper lid 200 and the cap body 100 may be completely separably coupled to each other.
[0063] Also, a protruding bump 203 protruding to an outer circumference side may be formed on an opposite side of the hinge coupling part 290 to separate the upper lid 200 from the cap body 100.
[0064] The protruding bump 203 that is a component formed on an outer circumferential surface of the upper lid 200 so that a user pushes the upper lid 200 by hands to separate the upper lid 200 from the cap body 100 may have various structures and shapes.
[0065] A coupling unit coupled by a fitting method may be disposed on the outer circumferential surface of each of the upper lid 200 and the cap body 100 to maintain a folded state when the upper lid 200 is separated from the cap body 100 and hinge-rotated.
[0066] For example, a first fitting part 181 may be formed below the hinge coupling part 290 on the outer circumferential surface of the cap body 100, and a second fitting part 281 fitted to the first fitting part 181 when the upper lid 200 is separated from the cap body 100 and hinge-rotated may be formed on the outer circumferential surface of the upper lid 200.
[0067] The first fitting part 181 and the second fitting part 281 are fitted to each other. Here, one is a projection, and the other is a groove part that forms a groove to which the projection is fitted.
[0068] The upper lid 200 may have a structure coupled with the upper plate part 101 of the cap body 100 in a state sealed from the outside.
[0069] Thus, the upper lid 20 may include a cover part 201 having a size and a shape (e.g., a circular plate shape) corresponding to the upper plate part 101 of the cap body 100, and a partition part 202 extending upward while forming an edge of the cover part 201.
[0070] The cover part 201 that is a component having a size and a shape (e.g., a circular plate shape) corresponding to the upper plate part 101 of the cap body 100 may have a shape corresponding to the upper plate part 101 of the cap body 100 except for the pushing plate that will be described later.
[0071] The partition part 202 that is a component extending upward while forming the edge of the cover part 201 and a component extending upward so that the pushing part 210 is not arbitrarily pushed may have a height equal to or greater than that of the pushing part 210.
[0072] Also, the partition part 202 may form a cylindrical shape together with the above-described container coupling part 151.
[0073] The partition part 202 may be coupled with the container coupling part 151 so that a space formed by the upper lid 200 and the cap body 100 is sealed from the outside.
[0075] To this end, a sealing coupling ring 250 closely contacting an inner circumferential surface or an outer circumferential surface of the container coupling part 151 and coupled with the container coupling part 151 may be formed at a lower end of the partition part 202.
[0076] The sealing coupling ring 250 that is a component formed at the lower end of the partition part 202 so as to closely contact the inner circumferential surface or the outer circumferential surface of the container coupling part 151 and be coupled with the container coupling part 151 may have various configurations such as a feature of closely contacting with the container coupling part 151.
[0077] As illustrated in FIGS. 1 to 12, the upper lid 200 includes the pushing part 210 formed in correspondence to the outlet plate 110 to fracture the outlet plate 110 by a vertical movement thereof.
[0078] The pushing part 210 that is a component formed in correspondence to the outlet plate 110 to fracture the outlet plate 110 by the vertical movement thereof may have various configurations.
[0079] For example, the pushing part 210 may include: a pushing plate 211 pushed by the user; an elastic deformation part 212 coupling the pushing part 210 with the upper lid 200 so as to be movable vertically with respect to the upper lid 200; and a pressing part 213 protruding from a bottom surface of the pushing plate 211 to press the outlet plate 110 downward when the pushing plate 211 moves downward.
[0080] The pushing plate 211 that is a portion pushed by the user may have a solid structure in consideration of a feature of being pressed by the user.
[0081] Here, the pushing plate 211 is formed at a position corresponding to the outlet plate 110 so that the outlet plate 110 is fractured and separated downward when the pushing plate 211 is pushed by the user.
[0082] The elastic deformation part 212 that is a component coupling the pushing part 210 with the upper lid 200 so as to be movable vertically with respect to the upper lid 200 may have various configurations.
[0083] For example, the elastic deformation part 212 may be a relatively thin film as a concentric structure with the pushing plate 211 or a component in which each of a portion connected to the pushing plate 211 and a portion connected to the cover part 201 is thinner than the rest portion.
[0084] The pressing part 213 that is a component protruding from the bottom surface of the pushing plate 211 to press the outlet plate 110 downward when the pushing plate 211 moves downward may have all sorts of configurations as long as the outlet plate 110 is fractured and separated from the upper plate part 101.
[0085] For example, as illustrated in FIGS. 1 to 12, the pressing part 213 may be formed in correspondence to a portion in which the outlet plate 110 is fractured and separated from the upper plate part 101, e.g., the cut line 131.
[0086] That is, the pressing part 213 may have a cross-sectional shape corresponding to a shape of the cut line 131.
[0087] For example, as illustrated in FIGS. 1, 2, 5b, and 12, the pressing part 213 may have a ring shape except for a portion in which the outlet plate 110 is connected to the upper plate part 101.
[0088] Also, a lower end of the pressing part 213 may have a sharp shape to promote breakage at the cut line 131
[0089] Also, the pressing part 213 may have a height sufficient to fracture and separate the outlet plate 110 from the upper plate part 101 by the vertical movement and be disposed in correspondence to an edge of the outlet plate 110 in a state in which the upper lid 200 is coupled to the cap body 100.
[0090] That is, the pressing part 213 may be formed in correspondence to the cut line 131 that is fractured with respect to the upper plate part 101.
[0091] The pushing part 210 may include a reinforcing part 214 formed inside the pressing part 213 to reinforce structural strength.
[0092] The reinforcing part 214 that is a component formed inside the pressing part 213 to reinforce structural strength may have various configurations.
[0093] For example, the reinforcing part 214 may have various configurations such as a rib or partition elongated vertically on an inner circumferential surface of the pressing part 213.
[0094] The above-disclosed subject matter is to be considered illustrative, and not restrictive, and the appended claims are intended to cover all such modifications, enhancements, and other embodiments, which fall within the true spirit and scope of the present invention.
