Description

[Technical Field]

[0001] The present invention relates to a container cap, and more particularly to a container cap that is coupled to the container inlet of a container filled with a content, and to the container to which the container cap is coupled. [Background technology]

[0002] A container cap is attached to the container inlet where the contents are filled, and the container is sealed. Various types of container caps are attached depending on the type of contents filled in the container, and the method of discharging or opening the container.

[0003] FIG. 1 is a perspective view showing a container to which a container cap according to the prior art is attached.

[0004] A container cap according to the prior art is a container cap that is coupled to a container 3 filled with granular contents such as gum, and can be configured as shown in FIG.

[0005] Specifically, the conventional container cap 1 shown in Figure 1 includes a main body 7 that is connected to the container inlet of the container 3 into which the contents are filled and that is open on the top, a cover 5 that is connected to the main body 7 and opens and closes the top opening of the main body 7, and a usage-marked belt 9 that is connected to the bottom end of the cover 5 and the top end of the main body 7 and that can be separated from the cover 5 and the main body 7 by the user, allowing the cover 5 to open and close the top opening of the main body 7.

[0006] Here, the usage-marked belt 9 is connected to the lower end of the cover part 5 and the upper end of the main body part 7, and is separated from the cover part 5 and the main body part 7 by the user, allowing the cover part 5 to open and close the upper opening of the main body part 7.

[0007] The usage mark belt 9 is formed together with the container cap 1 when it is formed by plastic injection molding, and is attached to the lower end of the cover part 5 and the upper end of the main body part 7. It is characterized in that it is separated from the lower end of the cover part 5 and the upper end of the main body part 7 along separation lines 7a, 7b, such as slit structures or multiple bridges, formed on the lower end of the cover part 5 and the upper end of the main body part 7, and then removed.

[0008] However, recently, due to the rapid increase in the amount of plastic used, waste plastic has become a major cause of environmental pollution, and there is a national and social demand to minimize or recycle the amount of plastic used.

[0009] On the other hand, in the conventional container cap shown in Figure 1, the usage mark belt 9 separates from the container cap 1 when it is used, which increases the amount of waste plastic used and makes it difficult to recycle the plastic material.

[0010] Furthermore, the conventional container cap shown in FIG. 1 has a problem in that the user must separate the usage trace belt 9 along the circumferential direction of the container cap 1, making the task of separating the usage trace belt 9 cumbersome. Summary of the Invention [Problem to be solved by the invention]

[0011] The object of the present invention is to solve the above-mentioned problems by realizing a plastic container cap that has an integrated structure for checking signs of use such as opening, thereby providing a container cap and a container to which it is attached that are easy to use and can be easily collected for recycling waste plastic. [Means for solving the problem]

[0017] The separation portion may be fitted and coupled to the fixing portion and fixed to the fixing portion.

[0018] The separation portion may be formed by bending the first connection portion vertically and connecting it to the fixing portion.

[0019] The fixing portion may include one or more second fitting coupling portions formed on an outer peripheral surface of the first member and fittingly coupled to one or more first fitting coupling portions provided on the separating portion.

[0020] The separation part may be coupled to the fixing part by moving in a vertical direction.

[0021] The fixing portion may include one or more second fitting coupling portions formed on an outer peripheral surface of the first member and fittingly coupled to one or more first fitting coupling portions provided on the separating portion.

[0022] The cover portion may be integrally connected to the main body portion by a hinge portion so as to rotate about a hinge when separated from the main body portion.

[0023] At least one of the separation portion and the fixing portion may be located at a position opposite the hinge portion, and the cover portion may be used as a grip portion for opening the main body portion by operation by a user.

[0024] The separation portion may be separated from the second member along a circumferential direction and fixedly coupled to a fixing portion formed on the first member.

[0025] The separation portion may have a belt structure connected by a plurality of bridges between the first member and the second member, and after being separated from the second member, may be inserted into a fixing portion formed on the outer peripheral surface of the second member and fixed thereto.

[0026] The cover portion may have a plurality of close contact portions that contact the container inlet, and the close contact portions may form a closed curve surrounding the container inlet to prevent external air from flowing into the container from the outside.

[0027] A container (container assembly) is disclosed that includes a container to be filled with contents, and a container cap that is coupled to a container inlet of the container and has the above-described configuration.

[0028] At least one of the cover portion and the container inlet may have a plurality of close contact portions that are in close contact with each other, and the close contact portions may form a closed curve surrounding the container inlet to prevent external air from flowing into the inside of the container from the outside. [Effects of the Invention]

[0031] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A container cap and a container (container assembly) to which the container cap is combined according to the present invention will now be described with reference to the accompanying drawings.

[0032] The container 30 is a container filled with granular or powdered contents, and can have any configuration as long as it can be filled with contents.It can have any shape and structure as long as it has a container inlet 20 to which the container cap 10 is attached.

[0033] Furthermore, it is preferable that the container 30 is filled with granular or powdered contents in consideration of the bonding strength of the container cap 10 according to the present invention, but it is of course also possible to fill it with liquid contents.

[0034] In addition, the container 30 can be sealed by a sealing member (not shown) attached to the opening of the container inlet 20 to prevent deterioration of the contents before use.

[0035] The main body 100 is connected to a container inlet 20 of a container 30 into which contents are to be filled, and has an opening formed on the upper side. Various configurations are possible depending on the connection structure with the container inlet 20.

[0036] For example, the main body 100 may have a ring shape corresponding to the shape of the horizontal end surface of the container inlet 20, such as a circle, an ellipse, or a polygon.

[0037] In addition, the main body 100 can be threadedly connected to the male thread portion formed on the outer peripheral surface of the container inlet 20, and therefore, a female thread portion can be formed on the inner peripheral surface of the main body 100 to be threadedly connected to the male thread portion of the container inlet 20.

[0038] The cover part 200 is coupled to the main body part 100 to open and close the upper opening of the main body part 100, and various configurations are possible.

[0039] In particular, the cover part 200 can have various configurations depending on the coupling structure with the main body part 100.

[0040] As an example, the cover part 200 may be connected to the main body part 100 in a completely separable manner, or may have a two-piece structure, as shown in FIG. 4C, and may be integrally connected to the main body part 100 by a hinge part 530 so that it can rotate on a hinge when separated from the main body part 100 (one-piece structure).

[0041] The hinge portion 530 is configured to integrally connect the cover portion 200 and the main body portion 100 so that the cover portion 200 rotates on a hinge when the cover portion 200 is separated from the main body portion 100, and various configurations are possible.

[0042] In addition, the cover part 200 may be connected to the body part 100 at the top and bottom by a separation line (not shown) or a number of bridges (not shown) in consideration of the bonding strength to the body part 100 before opening.

[0043] Due to this configuration, the hinge portion 530 can be integrally formed in the same manner as when the cover portion 200 and the main body portion 100 are injection molded.

[0044] Meanwhile, the cover part 200 can be connected to the main body part 100 in a state where it is detachably connected to the main body part 100 except for the separation part 300 described below, or in a state where it is detachably connected to the main body part 100 except for the separation part 300 and the hinge part 530 described below.

[0045] In this case, the cover part 200 can be connected to the main body part 100 using various conventional structures to keep the container 30 connected to the main body part 100 when not in use, and can close the upper opening of the main body part 100.

[0046] The cover part 200 can be coupled to a part of the upper end part of the container inlet 20 in addition to being coupled to the main body part 100 .

[0047] At this time, it is preferable that the cover part 200 is coupled to the upper end of the cover part 200 so that it can be separated from the body part 100 without rotating with respect to the container inlet 20 .

[0048] Furthermore, the cover 200 is preferably coupled to the container inlet 20 with a blocking structure, which will be described later, to prevent deterioration of the contents when coupled to the upper end of the container inlet 20 .

[0049] Meanwhile, the container cap 10 according to the present invention may be provided with a structure for checking for signs of use such as opening when it is first attached to the container inlet 20.

[0050] Specifically, the container cap 10 according to the present invention further includes a separation part 300 that is integrally connected to a first member, which is either the main body part 100 or the cover part 200, by a first connecting part 510, and that is detachably connected to a second member, which is the remaining one of the main body part 100 and the cover part 200, by a second connecting part 520.

[0051] The separation part 300 is integrally connected to a first member, which is either the main body part 100 or the cover part 200, by a first connecting part 510, and is detachably connected to a second member, which is the remaining one of the main body part 100 and the cover part 200, by a second connecting part 520, and various configurations are possible.

[0052] The first connecting portion 510 is configured to integrally connect the first member, for example, the cover portion 200 and the separation portion 300 described later, and is preferably formed of a film (thin film) having a thickness thinner than the side thickness of the cover portion 200 and the main body portion 100, taking into account the movement of the separation portion 300 after separation.

[0053] The first connecting portion 510 may have various widths, such as a width smaller than or equal to the width of the separating portion 300 in the circumferential direction.

[0054] The second connecting portion 520 is configured to detachably connect a second member, for example, the main body portion 100 and a separation portion 300 described later, and various configurations are possible.

[0055] In particular, the second connecting part 520 is characterized in that the cover part 200 can be separated from the main body part 100 by separating the second connecting part 520 through a user's operation.

[0056] Specifically, the second connecting part 520 may be formed with an incision groove or multiple bridges so that it can be easily separated by a user's operation, or may be formed in any manner such as by being easily separated or cut by a user's operation.

[0057] Meanwhile, the second connection part 520 may be connected to various structures and positions depending on the configuration of the separation part 300 and the second member, for example, the body part 100.

[0058] For example, the second connecting portion 520 may connect horizontally and / or vertically along the edge of the separating portion 300 .

[0059] In addition, the second connecting part 520 may be connected to the separating part 300 in a structure in which the separating part 300 is connected to the outer circumferential surface of the second member, for example, the main body part 100 .

[0060] Furthermore, it goes without saying that the second connecting portion 520 can be detachably coupled to the second member, for example, the main body portion 100, and the first member, for example, the cover portion 200.

[0061] The separation part 300 is integrally connected to the first member and detachably connected to the second member, and various embodiments are possible depending on the manner in which it is coupled to and separated from the cover part 200 and the body part 100.

[0062] At this time, the separation part 300 can connect the main body part 100 and the cover part 200 in the vertical direction as shown in FIGS. 2 to 20B.

[0063] In addition, the first member, for example, the cover part 200, preferably includes a fixing part 400 to which the separating part 300 is fixed after being separated from the second member.

[0064] The fixing part 400 is configured to be formed on the first member, for example, the cover part 200, so that it is fixed after the separation part 300 is separated from the second member, and various configurations are possible depending on the connection structure with the separation part 300.

[0065] For example, the separating part 300 can be fitted and coupled to the fixing part 400 and fixed to the fixing part 400, as shown in FIGS. 2 to 20B.

[0066] At this time, the separating part 300 can be coupled to the fixing part 400 by folding the first connecting part 510 in the vertical direction as shown in FIGS. 2 to 17B.

[0067] The fixing part 400 may include one or more second fitting coupling parts 420 formed on the outer circumferential surface of the first member and fitted and coupled to one or more first fitting coupling parts 320 provided in the separating part 300.

[0068] 18A to 20B, the separating part 300 can be moved in the vertical direction and coupled to the fixing part 400. As shown in FIG.

[0069] Meanwhile, the fixing part 400 may include one or more second fitting coupling parts 420 formed on the outer circumferential surface of the first member and fitted and coupled to one or more first fitting coupling parts 320 provided in the separating part 300.

[0070] The first fitting coupling portion 320 and the second fitting coupling portion 420 are configured to be coupled according to various fitting coupling structures shown in Figures 2 to 21C, and various configurations such as protrusions and grooves are possible depending on the inter-fit coupling structure.

[0071] Meanwhile, the separating part 300 may connect the body part 100 and the cover part 200 in the circumferential direction.

[0072] The separating portion 300 may be separated from the second member along the circumferential direction and fixedly coupled to the fixing portion 400 formed on the first member.

[0073] The above-described connection structure can be realized by arranging and connecting the structures shown in FIGS. 2 to 20B in a circumferential direction instead of a vertical direction.

[0074] As another example, the separating part 300 may have a belt structure connected by a plurality of bridges between the first member and the second member, as shown in Figures 21A to 21C, and after being separated from the second member, may be inserted into and fixed to a fixing part 400 formed on the outer circumferential surface of the second member.

[0075] Meanwhile, the separation part 300 can be coupled to the fixing part 400 at various angles, such as by rotating upward at an angle of 90 degrees or by rotating 180 degrees.

[0076] Furthermore, the coupling structure of the separating part 300 and the fixing part 400 can be any structure as long as it is a structure in which a protruding part and a protruding part are inserted corresponding to the protruding part.

[0077] In particular, the primary operation of pushing the separating part 300 upward to connect it to the fixing part 400 and the secondary operation of pushing the connected separating part 300 and fixing part 400 upward to open it upward as shown in FIG. 5D are performed in a single operation (one-touch method), which provides the advantage of convenient opening of the container 30.

[0078] In relation to the configuration of the separating part 300, in consideration of the convenience of separating the cover part 200, an embodiment of the separating part 300 will be described below in which the cover part 200 is a first member and the main body part 100 is a second member.

[0079] First Example (Figs. 2 to 5C) A first embodiment of the coupling structure of the separation portion and the fixed portion will be described below.

[0080] As shown in Figures 2 and 4A to 4C, the separation portion 300 can be formed as a first fitting coupling portion 320, which includes a base portion 301 formed to protrude from the cover portion 200 to the main body portion 100 and a pair of protrusions 310 protruding in the radial direction and spaced apart in the circumferential direction.

[0081] At this time, the separation part 300 is connected to the main body part 100 by a second connection part 520 consisting of an incision line or a plurality of bridges (not shown).

[0082] The main body 100 has a recessed groove 130 formed in a shape corresponding to the front shape of the separating portion 300 .

[0083] The fixing part 400 may be formed by protruding a first fitting coupling part 320 formed by a pair of protrusions 310 on the outer circumferential surface of the cover part 200, i.e., one or more second fitting coupling parts 420 having a width corresponding to the groove.

[0084] The second fitting coupling part 420 is formed on the outer circumferential surface of the cover part 200 as a protrusion having a width corresponding to the groove formed by the pair of protrusions 310, and may have various configurations.

[0085] Meanwhile, the separation part 300 and the fixing part 400 may be formed at positions opposite to the hinge part 530 described above, and the separation part 300 and the fixing part 400 coupled to each other may be used as a gripping part for separating the cover part 200 from the main body part 100 and opening the container 30 by the user's operation.

[0086] At this time, the separation part 300 may be pushed upward by the user, and at this time, the second connecting part 520 is cut, and the first connecting part 510 is folded upward as shown in Figures 3, 5A to 5D, and the separation part 300 and the fixing part 400 are connected to each other.

[0087] As described above, the separation part 300 and the fixing part 400, which are connected to each other, can be operated by the user to separate the cover part 200 from the main body part 100, thereby making it possible to open the container 30 with a single operation, a so-called one-touch operation.

[0088] Second Example (Figs. 6 to 9C) A second embodiment of the separating portion and the fixing portion will now be described.

[0089] The structure according to the second embodiment differs from that of the first embodiment in the coupling structure with the fixed portion.

[0090] First, the second fitting coupling portion 420 of the fixing part 400 may be composed of one or more protrusions inserted into the fitting groove 321 formed in the first fitting coupling portion 320 of the separating part 300, as shown in Figures 6 and 8A to 8C.

[0091] The protrusions are configured to be inserted into the fitting grooves 321 formed in the first fitting coupling portion 320 of the separation portion 300, and can be formed in numbers and positions corresponding to the fitting grooves 321 formed in the first fitting coupling portion 320 of the separation portion 300.

[0092] The first fitting coupling portion 320 of the separation portion 300 may be formed as a fitting post protruding from the base portion 301 formed to protrude from the cover portion 200 to the main body portion 100, and having a fitting groove 321 formed therein into which the protrusion formed on the fixing portion 400 is fitted.

[0093] The mating pillar is formed to protrude from the base portion 301 formed to protrude from the cover portion 200 to the main body portion 100, and is configured to have a mating groove 321 formed therein into which the protrusion formed on the fixing portion 400 is fitted, and various configurations are possible.

[0094] In particular, it is preferable that the engaging pillar has a tip portion inclined in the circumferential direction as shown in FIG. 8A so that the separating portion 300 is bent upward and the protruding portion of the fixing portion 400 can be easily inserted and fixed.

[0095] More specifically, the mating posts may be formed in pairs, with their ends inclined downwards in a direction that allows them to be seen from each other.

[0096] Meanwhile, the separation part 300 is connected to the main body part 100 by a second connection part 520 consisting of an incision line or a plurality of bridges (not shown).

[0097] The main body 100 has a recessed groove 130 formed therein, which corresponds to the front shape of the separating portion 300 .

[0098] Meanwhile, the forming positions of the separation part 300 and the fixing part 400 are located opposite to the aforementioned hinge part 530, and the separation part 300 and the fixing part 400 connected to each other can be used as a gripping part to separate the cover part 200 from the main body part 100 by the user's operation and open the container 30.

[0099] At this time, the separation part 300 may be pushed upward by the user's operation, and at this time, the second connection part 520 is cut, so that the separation part 300 is separated from the main body part 100.

[0100] 7 and 9A to 9C, the first connecting portion 510 of the separation portion 300 is folded upward, and the separation portion 300 is coupled to and fixed to the fixing portion 400. As shown in FIG.

[0101] Third Example (FIGS. 10A to 11C) A third embodiment of the coupling structure of the separation portion and the fixed portion will now be described.

[0102] The connecting structure of the separating portion and the fixing portion according to the third embodiment is a modified fitting connecting structure compared to the first and second embodiments.

[0103] As shown in Figures 10A to 10C, the separation part 300 is a base part 301 formed to protrude from the cover part 200 to the main body part 100, and a protrusion formed to protrude from the upper end part of the base part 301, and includes a first fitting coupling part 320.

[0104] The base part 301 is configured to be separable from the main body part 100 by the second connecting part 520, and may have various shapes.

[0105] At this time, in order to form the base portion 301, the main body portion 100 is formed with a recessed groove 130 corresponding to the front shape of the separation portion 300.

[0106] At this time, the portion where the groove 130 is formed may have an inclined portion 140 extending toward the bottom surface of the separation portion 300, corresponding to the lower end of the separation portion 300, as shown in Figures 10A to 11C, so as to facilitate separation of the separation portion 300.

[0107] The inclined portion 140 is formed to incline toward the bottom surface of the separation part 300 in correspondence with the lower end of the separation part 300, so that the user's fingers can be placed on the lower end of the separation part 300 to facilitate separation of the separation part 300.

[0108] Meanwhile, the separating part 300 is connected to the cover part 200 by a first connecting part 510, and the first connecting part 510 may be connected in various structures.

[0109] That is, unlike the first and second embodiments, the first connecting part 510 is a pair and can integrally connect the separating part 300 and the cover part 200 on both sides.

[0110] The first fitting coupling part 320 may be formed as a protrusion protruding from the upper end of the base part 301, or may be formed as a single protrusion at the center.

[0111] Meanwhile, the fixing part 400 coupled to the separating part 300 may be formed with a second fitting coupling part 420 as a recess into which the first fitting coupling part 320 is inserted.

[0112] In this case, the fixing part 400 may have a recess formed therein so that the remaining portion of the upper end of the base part 301 is inserted therein.

[0113] Meanwhile, as described above, the separation part 300 and the fixing part 400 are located opposite the hinge part 530, and the separation part 300 and the fixing part 400 coupled to each other can be used as a gripping part that separates the cover part 200 from the main body part 100 by the user's operation to open the container 30.

[0114] Fourth embodiment (Figs. 12A to 13B) A fourth embodiment of the coupling structure of the separation portion and the fixed portion will now be described.

[0115] The coupling structure of the separating portion and the fixing portion according to the fourth embodiment is a modified example of the second fitting coupling portion 420 constituting the fixing portion 400 compared to the first embodiment.

[0116] In the case of the connection structure of the separation part and the fixing part according to the first embodiment shown in Figures 2 to 5C, the protrusion constituting the second fitting connection part 420 of the fixing part 400 may be pressed during distribution or due to carelessness by the user, causing the cover part 200 to be separated from the main body part 100.

[0117] Therefore, in the configuration of the first embodiment, as shown in FIGS. 12A to 13B, the second fitting coupling portion 420 of the fixed portion 400 can be configured with a thin film.

[0118] When the second fitting coupling portion 420 of the fixing part 400 is made of a thin film, even if an upward force is applied to the second fitting coupling portion 420 of the fixing part 400 during distribution or due to a user's carelessness, only the second fitting coupling portion 420 of the fixing part 400 is pushed upward, thereby eliminating the problem of the cover part 200 being separated from the main body part 100.

[0119] Fifth embodiment (FIGS. 14A and 14B) A fifth embodiment of the coupling structure of the separation portion and the fixed portion will be described below.

[0120] The coupling structure of the separating portion and the fixing portion according to the fifth embodiment is a modified example of the first fitting coupling portion 320 and the second fitting coupling portion 420 compared to the first embodiment.

[0121] The first fitting coupling part 320 may be composed of a protrusion protruding from the center part of the base part 301, and the second fitting coupling part 420 may be composed of a pair of groove forming protrusions that form a groove into which the protrusion of the first fitting coupling part 320 is inserted.

[0122] As a variation of the structure shown in Figures 14A and 14B, the first connecting part 510 is folded and fitted into the groove formed by a pair of groove-forming protrusions, and the base part 301 is hung on the upper end of the groove-forming protrusions, thereby connecting the separation part 300 and the fixing part 400.

[0123] Sixth embodiment (Figs. 15A to 16B) A sixth embodiment of the coupling structure of the separation portion and the fixed portion will be described below.

[0124] The coupling structure of the separation part and the fixing part according to the sixth embodiment is a modified example of the first fitting coupling part 320 and the second fitting coupling part 420 compared to the first embodiment.

[0125] The first fitting coupling portion 320 may be configured as a groove formed in the base portion 301, and the second fitting coupling portion 420 may be configured as a fitting coupling protrusion inserted into the groove formed in the first fitting coupling portion 320.

[0126] Specifically, when the upper side of the base part 301 is pushed up by the user's operation, the first connecting part 510 is folded, and the base part 301 rotates upward with the first connecting part 510 as a base.

[0127] The base part 301 is rotated to face the second fitting coupling part 420, and the fitting coupling protrusion of the second fitting coupling part 420 is inserted into the groove formed in the base part 301 and coupled.

[0128] At this time, in order to facilitate the first and second fitting coupling portions 320 and 420, one or more guide protrusions 440 for guiding the coupling of the first and second fitting coupling portions 320 and 420 may be formed on the outer circumferential surface of the cover portion 200 at a portion corresponding to the outer edge of the base portion 301.

[0129] The guide protrusion 440 is formed on the outer peripheral surface of the cover part 200 to guide the connection of the first fitting coupling part 320 and the second fitting coupling part 420 at a portion corresponding to the outer edge of the base part 301, and various configurations are possible depending on the front shape of the base part 301.

[0130] For example, when the front shape of the base part 301 is rectangular, the guide protrusion 440 may be formed in an L-shape corresponding to the vertex of the rectangular front shape.

[0131] Seventh embodiment (FIGS. 17A and 17B) A seventh embodiment of the coupling structure between the separated portion and the fixed portion will now be described.

[0132] The coupling structure of the separating portion and the fixing portion according to the seventh embodiment is a modified example of the first fitting coupling portion 320 and the second fitting coupling portion 420 compared to the first embodiment.

[0133] The first fitting coupling part 320 may be composed of three groove forming protrusions that form two grooves in the horizontal direction, and the second fitting coupling part 420 may be composed of two protrusions that fit into the two grooves formed by the three groove forming protrusions.

[0134] With the above-described structure, when the separation part 300 is separated from the main body part 100 and pushed upward, the three groove forming protrusions formed on the base part 301 face two protrusions.

[0135] The two protrusions of the second fitting coupling part 420 are fitted into the two grooves formed by the three groove-forming protrusions, whereby the separating part 300 is fixedly coupled to the fixing part 400 .

[0136] Eighth embodiment (FIGS. 18A and 18B) An eighth embodiment of the coupling structure of the separation portion and the fixed portion will now be described.

[0137] The coupling structure of the separating portion and the fixing portion according to the eighth embodiment is a modified example of the moving structure of the first fitting coupling portion 320 and the coupling structure of the first fitting coupling portion 320 and the second fitting coupling portion 420 compared to the first embodiment.

[0138] First, the separating part 300, that is, the first fitting coupling part 320, is characterized in that it moves up and down to be coupled to the fixing part 400, as shown in FIGS. 18A to 20B. To this end, the first fitting coupling part 320 can have various configurations depending on the fitting coupling structure of the second fitting coupling part 420.

[0139] For example, the first fitting coupling portion 320 may include a head portion 323 and an extension portion 324 having a width smaller than that of the head portion 323 .

[0140] The head portion 323 can have any structure as long as it has a width greater than the width of the groove formed by a pair of protrusions that form the second mating coupling portion 420 described below so as to pass through the groove and maintain the locked state.

[0141] In particular, the head portion 323 preferably has a wedge shape so that it can pass through the recessed groove formed by the pair of protrusions and maintain the locked state.

[0142] The extension portion 324 is a portion formed by extending downward from the head portion 323, and can be placed between the grooves formed by the pair of protrusions after the head portion 323 passes through the grooves formed by the pair of protrusions.

[0143] Meanwhile, the first fitting coupling part 320 may be formed with a horizontally extending locking part 325 that is locked to a pair of protrusions to prevent the head part 323 from moving excessively.

[0144] The locking portion 325 is configured to be locked by a pair of protrusions to prevent the head portion 323 from moving excessively, and various configurations are possible.

[0145] Furthermore, the locking portion 325 may have an upper extension portion 326 extending upward so as to form a groove together with the extension portion 324 into which each of the pair of protrusions is inserted.

[0146] Meanwhile, the second connecting part 520 may be formed between the bottom surface of the separating part 300 and the outer circumferential surface of the main body part 100 .

[0147] Furthermore, in order to form the separation portion 300, the groove 130 corresponding to the front shape of the separation portion 300 does not necessarily need to be formed in the body portion 100.

[0148] Meanwhile, the second fitting coupling portion 420 constituting the fixing portion 400 may be configured with a pair of protrusions forming a groove smaller than the horizontal width of the head portion 323 so that the head portion 323 can be fitted and locked.

[0149] The pair of fitting coupling protrusions are configured to form a recessed groove smaller than the horizontal width of the head portion 323 so that the head portion 323 can be fitted and locked, and various configurations are possible.

[0150] Ninth Example (Figs. 19A to 20B) A ninth embodiment of the coupling structure of the separating portion and the fixing portion will be described below.

[0151] The coupling structure of the separation part and the fixing part according to the ninth embodiment is a modified example of the second fitting coupling part 420 compared to the second embodiment.

[0152] Specifically, the second fitting coupling portion 420 may include a pair of primary protrusions that keep the head portion 323 fitted before the separation portion 300 is separated from the main body portion 100, and a pair of secondary protrusions through which the head portion 323 passes and engages as the head portion 323 moves upward after the separation portion 300 is separated from the main body portion 100.

[0153] Tenth Example (Figs. 21A to 21C) A ninth embodiment of the coupling structure of the separation portion and the fixed portion will now be described.

[0154] The coupling structure of the separation portion and the fixing portion according to the ninth embodiment is an embodiment in which the structures shown in FIGS. 2 to 20B are arranged and coupled in the circumferential direction, rather than in the vertical direction.

[0155] Specifically, as shown in Figures 21A to 21C, the separation part 300 has a belt structure connected to the cover part 200 and the main body part 100 by multiple bridges (not shown), and after being separated from the cover part 200 and the main body part 100, it can be inserted into and fixed in a fixing part 400 formed on the outer peripheral surface of either the cover part 200 or the main body part 100.

[0156] At this time, at least a portion of the outer periphery of the cover part 200 and the fixing part 300 may be cut out in a portion where the separating part 300 is located in order to install the separating part 300 .

[0157] In addition, for ease of separation of the separating part 300, a separating grip part 570 that can be held by a user may be formed at the tip part.

[0158] Meanwhile, the separation part 300 is integrally connected to the cover part 200 and the main body part 100 on the side where the fixing part 400 is formed by the first connecting part 510 so that the end part close to the fixing part 400 is folded in the circumferential direction.

[0159] The fixing part 400 is formed on the side of the cover part 200 and the main body part 100 to which the separation part 300 is connected, and may have any configuration as long as it is configured to fix the separation part 300.

[0160] For example, the fixing part 400 may have a structure in which a through hole is formed to fit in the circumferential direction, taking into consideration the separating part 300 having a belt structure.

[0161] Meanwhile, the cover part 200 can be hinge-rotatably connected to the main body part 100 by the hinge part 530, and at this time, a grip part 580 can be formed at a position opposite the hinge part 530 so that a user can easily separate the cover part 200 from the main body part 100.

[0162] The role of the gripper and injection molding Meanwhile, in the container cap 10 according to the present invention, at least one of the separating part 300 and the fixing part 400 is positioned opposite the hinge part 530, and the mutually coupled separating part 300 and fixing part 400 can be used as a gripping part for separating the cover part 200 from the main body part 100 by the user's operation to open the container 30.

[0163] Meanwhile, the container cap 10 having the above-described structure can be formed by injection molding using a synthetic resin material.

[0164] In this regard, in the container cap 10 according to the present invention, it is preferable that the body part 100, the cover part 200 and the separating part 300 are integrally formed in consideration of ease of manufacturing and recycling after use.

[0165] Container structure Meanwhile, the container cap 10 having the above-described structure can be attached to containers of various structures.

[0166] In particular, the container cap 10 according to the present invention is suitable for a container 30 filled with powder, particularly a granular content, and the container 30 structure can also be specialized for discharging granular content.

[0167] Specifically, the container 30 according to the present invention can be provided with a partition member 640 that forms a discharge path 33 for the contents, as shown in FIGS.

[0168] The partition member 640 is provided inside the container 30 and is configured to form a discharge path 33 for the contents, and various configurations are possible.

[0169] For example, the partition member 640 may form a content communication passage 39 that connects the lower end to the discharge path 33 .

[0170] On the other hand, the partition member 640 forms two passages at the upper end, namely, a discharge path 33 and an inlet path 31 through which the contents flow inside, and as shown in Figure 23, when it is tilted from the horizontal line, it is necessary to block the contents from being discharged through the inlet path 31.

[0171] For this purpose, the container 30 can be provided with a rotatable door member 620 at the upper end of the inflow passage 31 for opening and closing the inflow passage 31 according to the inclination angle of the container 30 .

[0172] The door member 620 is provided at the upper end of the inflow passage 31 and is configured to open and close the inflow passage 31 according to the inclination angle of the container 30, and various configurations are possible.

[0173] At this time, the door member 620 is to be supported and installed inside the container 30, and can be connected to the inner surface of the container 30 by a hinge part 630 to which the door member 620 is connected so as to be hinged and an installation coupling part 610 to which the installation coupling part 610 is coupled to a support coupling part 35 formed on the inner surface of the container 30.

[0174] In addition, in order to prevent excessive rotation of the door member 620 when it rotates, a locking portion 641 may be formed at the upper end of the partition member 640 to lock the door member 620 and prevent excessive rotation of the door member 620.

[0175] Meanwhile, the container 30 according to the present invention must be able to smoothly discharge the granular content towards the discharge path 33, and the bottom structure may have various structures as shown in Figures 22 to 26C.

[0176] Specifically, the container 30 may be formed with a vertex 37 protruding from the end so that the granular content is discharged to the discharge path 33 side.

[0177] The apex portion 37 is configured to protrude from the tip so that the granular contents are discharged toward the discharge path 33, and in order to enhance the formation effect, it is preferable that the height H is formed to be greater than 1 / 4 of the lower end diameter D of the container 30.

[0178] On the other hand, by forming the apex portion 37, an inclined surface 36 that slopes toward the lower edge of the container 30 is formed, and the contents can be guided to the lower edge of the container 30.

[0179] The vertex 37 may be formed in a symmetrical structure with respect to the center, as shown in FIGS. 25A and 25B, 26A and 26B.

[0180] In particular, it is preferable that the apex portion 37 is asymmetrical and formed on the side farther from the discharge path 33 in order to induce the contents to flow toward the discharge path 33, as shown in Figures 22, 23, 25C and 26C.

[0181] At this time, the inclined surface 36 may be formed with a plurality of ribs 651 protruding upward from the bottom surface in order to guide the movement of the contents.

[0182] As shown in Figures 25B and 25C, the multiple ribs 651 are parts formed on the inclined surface 36 that protrude upward from the bottom surface to guide the movement of contents, and can be formed in various structures.

[0183] Meanwhile, if external air or the like flows into the container 30, deterioration of the contents may occur. Therefore, it is preferable that the container cap 10 coupled to the container inlet 20 has a blocking structure that can block the inflow of external air through the container inlet 20 as much as possible.

[0184] As a result, at least one of the container cap 20 and the container inlet 12 forms a plurality of close contact portions that are in close contact with each other, and the close contact portions can form a closed curve surrounding the container inlet 20 to prevent external air from flowing into the inside of the container 30 from the outside.

[0185] In particular, it is preferable that the blocking structure for sealing the inside of the container 30 is provided on the cover part 200 coupled to the upper end part of the container inlet 20 .

[0186] That is, the cover part 200 may include an inner ring 290, a so-called ring gasket, which protrudes from the bottom surface and is inserted into the inner circumferential surface of the container inlet 20 in order to enhance the sealing force of the container 30.

[0187] The inner ring 290 is a part that protrudes from the bottom surface of the cover part 200 and is inserted into the inner surface of the container inlet 20 to increase the sealing force of the container 30, and various configurations are possible depending on the contact structure with the container inlet 20.

[0188] The cover part 200 can be connected by a snap-type connection structure (for example, one-piece and two-piece one-touch cap and undercut cap structure).

[0189] Here, the snap-type connection structure refers to a structure in which a circular ring protrudes from the outer peripheral surface of the container inlet 20, and a ring-shaped locking protrusion that locks onto the circular ring of the container inlet 20 is formed on the inner peripheral surface of the container cap 10, thereby connecting them together.

[0190] The screw connection structure refers to a structure in which a male thread portion is formed on the outer peripheral surface of the container inlet 20 and a female thread portion that is screwed together with the male thread portion is formed on a part of the inner peripheral surface of the container cap 10.

[0191] In this case, the container inlet 20 has one or more ring-shaped coupling protrusions 24 formed on its outer circumferential surface, and the cover part 200 has ring-shaped coupling protrusions 290 formed on its inner circumferential surface into which the coupling protrusions 24 formed on the container inlet 20 are inserted, thereby allowing the cover part 200 to be coupled to the container inlet 20.

[0192] The body 100 coupled to the cover 200 can be coupled to the container inlet 20 in various ways, such as by screw coupling or snap coupling.

[0193] Meanwhile, the cover part 200 may be in relatively close contact with the container inlet 20 to form a plurality of close contact parts that are in close contact with the container inlet 20 .

[0194] The close contact portion forms a closed curve surrounding the container inlet 20 to prevent external air from flowing into the container 30 from the outside, and various configurations are possible depending on the position, structure, and number of the close contact portion.

[0195] The blocking structure will be described in detail below with reference to more specific examples. For the sake of convenience, only the characteristic features will be described in detail.

[0196] Although the blocking structure has been described in terms of the individual embodiments, it is of course possible to combine one or more of the embodiments as long as they are not contradictory to each other.

[0197] <First Example> As shown in FIG. 27A, the cover portion 200 may be formed with one or more inner peripheral protrusions 21 that protrude toward the inner ring 290 so as to contact the outer peripheral surface of the inner ring 290 when the cover portion 200 is coupled to the container inlet 20.

[0198] The inner protrusion 21 is a part that protrudes toward the inner ring 290 so as to come into contact with the outer surface of the inner ring 290, and may have a ring shape in the circumferential direction based on the longitudinal central axis of the cover part 200.

[0199] The inner peripheral protrusion 21 is preferably formed so that the longitudinal end face of the container inlet 20 forms a gentle curve so as to make surface contact rather than line contact with the outer peripheral surface of the inner ring 290 .

[0200] Meanwhile, the cover portion 200 has the same configuration as the inner peripheral protrusion portion 21 described above, and may have one or more inner ring protrusions that protrude toward the inner peripheral surface of the cover portion 200 so as to come into contact with the inner peripheral surface of the cover portion 200 when the cover portion 200 is coupled to the container inlet 20.

[0201] The inner ring protrusion is configured to protrude toward the inner surface of the cover part 200 so as to come into contact with the inner surface of the cover part 200 when the cover part 200 is connected to the container inlet 20, and may have a ring shape in the circumferential direction based on the longitudinal central axis of the container inlet 20.

[0202] The inner ring protrusion is preferably formed to have a gentle curve so that the longitudinal end face of the container inlet 20 makes surface contact with the inner peripheral surface of the container inlet 20 rather than line contact.

[0203] Meanwhile, in order to increase the sealing force for the container 30, the cover part 200 is inserted into a groove 220 integrally formed along the circumference at the upper end of the container inlet 20, and when the cover part 200 is coupled to the container inlet 20, a middle ring 210 can be formed on the bottom surface of the cover part 200.

[0204] The middle ring 210 is inserted into a groove 220 integrally formed around the circumference at the upper end of the container inlet 20, and is a ring formed on the bottom surface of the cover part 200 when the cover part 200 is connected to the container inlet 20, and various configurations are possible depending on the contact structure with the groove 220.

[0205] For example, the vertical cross section of the middle ring 210 may be an inverted triangle or an inverted trapezoid, and the tip of the middle ring 210 may have various shapes such as a flat surface or a curved surface.

[0206] The groove 220 into which the middle ring 210 is inserted may be formed in a shape corresponding to the end face shape of the middle ring 210, and it is preferable that the width of the end face shape of the middle ring 210 is reduced to a greater extent so that the middle ring 210 fits tightly as it is inserted.

[0207] Meanwhile, it is needless to say that two or more grooves 220 and middle rings 210 may be formed depending on the sealing force.

[0208] Meanwhile, in forming the groove 220, the groove 220 can be formed by two (inner and outer) upper end portions 221 and 222 that form the upper end of the container inlet 20.

[0209] At this time, it is preferable that the two upper end portions 221 and 222 are formed in a structure that is inclined at the portion forming the groove 220 and has elasticity.

[0210] At least one of the two upper end portions 221, 222 preferably has a curved outer periphery.

[0211] In this case, as shown in FIG. 27A, the cover part 200 has an inclined surface 215 that contacts the curved outer peripheral surface of the upper end portions 221 and 222, so that when the cover part 200 is coupled to the container inlet 20, the cover part 200 and the container inlet 20 can be in close contact, i.e., form one or more close contact parts.

[0212] Meanwhile, the upper end of the container inlet 20, that is, the two upper end portions 221 and 222, may be formed such that the inner upper end 221 is lower than the outer upper end 222 with respect to the groove 220 as the center.

[0213] <Second Example> The upper end portion of the container inlet 20 may be formed with one or more contact rings 950, 960 extending to the lower end of the cover portion 200 so as to be in close contact with the upper end portion of the container inlet 20, as shown in FIG. 27B, in addition to or in addition to a structure similar to that of the first embodiment.

[0214] The contact rings 950 and 960 are portions that extend to the lower end of the cover part 200 so as to come into close contact with the upper end portion of the container inlet 20, and may be ring-shaped.

[0215] In particular, the contact rings 950, 960 may be comprised of an inner ring 950 and an outer ring 960, such that the upper end portion of the container inlet 20 fits therein.

[0216] <Third Example> Meanwhile, when the cover part 200 and the container inlet 20 are sealed, if the contacting portions are given flexibility, the sealing force of the container can be significantly improved.

[0217] As a result, as shown in Figures 28A to 28D, one or more flexibility grooves 231, 232, 233 are formed in the container inlet 20, and pressure contact portions 241, 242, 243, 215 that come into pressure contact at positions corresponding to the flexibility grooves 231, 232, 233 are formed in the cover portion 200.

[0218] The flexibility-imparting grooves 231, 232, and 233 are grooves formed to improve the sealing force of the container by imparting flexibility to the area where the cover part 200 and the container inlet 20 come into contact with each other, and can be formed in any area where the cover part 200 and the container inlet 20 come into contact with each other.

[0219] As an example, the flexibility grooves may be flexibility grooves 231, 233 formed at the upper end of the container inlet 20, as shown in Figures 28A and 28C.

[0220] The flexibility-imparting grooves 231 and 233 formed at the upper end of the container inlet 20 are ring-shaped grooves formed at the upper end of the container inlet 20, and may be the recessed grooves 220 presented in the first embodiment.

[0221] In particular, it is preferable that the flexibility-imparting grooves 231, 233 formed at the upper end of the container inlet 20 are formed close to the inner surface (Figure 28C) or outer surface (Figure 28A) at the upper end of the container inlet 20 so that they can deform when they come into contact with the cover portion 200.

[0222] On the other hand, as another example, if the flexibility-imparting groove 232 formed at the upper end of the container inlet 20 is formed close to the inner surface at the upper end of the container inlet 20 as shown in Figure 28B, the cover part 200 can form an inclined surface 215 or the like at a corresponding position, so that when the cover part 200 is attached to the container inlet 20, the part where the flexibility-imparting groove 232 is formed can be brought into pressure contact as the pressure contact part 215.

[0223] When the flexibility-imparting groove 231 formed at the upper end of the container inlet 20 is formed close to the outer peripheral surface at the upper end of the container inlet 20 as shown in Figure 28A, the cover part 200 can form an inclined surface 241 or the like at a corresponding position, so that when the cover part 200 is attached to the container inlet 20, the part where the flexibility-imparting groove 231 is formed can be brought into pressure contact as the pressure contact part 241.

[0224] Meanwhile, in addition to a simple inclined surface when forming the pressure contact portion 241 on the cover portion 200, as shown in FIG. 28B, the pressure contact portion 241 can be formed on the outer ring 950 presented in the second embodiment.

[0225] As another example, the flexibility groove 232 may be a flexibility groove 232 formed in the outer periphery of the container inlet 20, as shown in FIG. 28B.

[0226] At this time, in order to form the flexibility groove 232 that is pressed against the cover part 200, a ring-shaped flexibility protrusion 230 is formed on the outer peripheral surface of the container inlet 20, and the flexibility groove 232 is formed in a concave shape from the top to the bottom of the flexibility protrusion 230, thereby forming the flexibility groove 232.

[0227] The cover part 200 may have a pressure contact part 242 formed on the inner circumferential surface thereof corresponding to the flexibility-imparting groove 232 .

[0228] The pressure contact portion 242 may be formed as an inclined surface that is inclined upward so that when the cover portion 200 is coupled to the container inlet 20, the cover portion 200 moves downward to apply pressure to the portion of the flexibility-imparting protrusion 230 where the flexibility-imparting groove 232 is formed.

[0229] As described above, the pressure contact parts 241, 242, and 215 are formed on the cover part 200 and come into pressure contact at positions corresponding to the flexibility-imparting grooves 231, 232, and 233, and any structure is possible as long as it can apply pressure to the parts where the flexibility-imparting grooves 231, 232, and 233 are formed.

[0230] Specifically, it is preferable that the pressure contact portions 241, 242, 215 are formed on an inclined surface in consideration of the fact that when the cover portion 200 rotates and / or descends relative to the container inlet 20, the force applied by the descent presses the portions where the flexibility-imparting grooves 231, 232, 233 are formed.

[0231] However, the pressure contact portions 241, 242, and 215 may have various structures such as protrusions other than inclined surfaces as long as they can pressurize the portions where the flexibility-imparting grooves 231, 232, and 233 are formed by the force applied by descending.

[0232] <Fourth Example> Meanwhile, various embodiments are possible, such as intentionally increasing the area of ​​close contact between the cover part 200 and the container inlet 20 when they are combined to improve the sealing force of the container.

[0233] Compared to the configuration shown in FIG. 28A, the cover part 200 may further include an auxiliary inner ring 280 between the upper end portion of the container inlet 20 and the inner ring 290.

[0234] The auxiliary inner ring 280 may be formed between the upper end portion of the container inlet 20 and the inner ring 290, protruding downward from the bottom surface of the cover part 200.

[0235] At this time, it is preferable that the auxiliary inner ring 280 is formed shorter than the vertical length of the inner ring 290 in order to prevent interference with the inner ring 290 .

[0236] It is preferable that the auxiliary inner ring 280 has a sloped surface facing the upper end portion of the container inlet 20, and in this case, it is preferable that the upper end portion of the container inlet 20 also has a sloped surface as a pressure contact portion 241 at the portion that contacts the auxiliary inner ring 280.

[0237] Meanwhile, the container inlet 20 can be formed with an inner peripheral protrusion 21 that contacts the outer peripheral surface of the inner ring 290, as described in the first embodiment.

[0238] The above structure increases the contact area between the cover part 200 and the container inlet 20, thereby improving the sealing force of the container.

[0239] As shown in FIG. 29B, the pressure contact portion 241 for applying pressure to the portion where the flexibility-imparting groove 234 is formed can be formed on the inclined surface as part of the inner ring 290 (inner ring 290 and auxiliary inner ring 280 can be considered to be integrated with each other) instead of being configured as the auxiliary inner ring 280.

[0240] Meanwhile, in the embodiment shown in Figures 29A and 29B, in connection with the formation of the flexibility-imparting groove 231 or recessed groove 220, as shown in Figure 28A, it can be formed by an inner upper end portion 222 and an outer upper end portion 221, and the heights of the inner upper end portion 222 and the outer upper end portion 221 can be the same or one of them can be formed higher.

[0241] In particular, in FIGS. 29A and 29B, the height of the inner upper end portion 222 may be smaller than the height of the outer upper end portion 221.

[0242] On the other hand, the flexibility-imparting groove 234 can be formed close to the outer peripheral surface of the upper end of the container inlet 20, as shown in FIG. 29C.

[0243] Here, the cover part 200 may have an inclined surface 215 as a pressure contact part 215 so that the part where the flexibility-imparting groove 234 is formed can be pressed. In FIG. 29C, the height of the outer upper end portion 221 can be formed smaller than the height of the inner upper end portion 222.

[0244] Also, as shown in FIG. 29D, a protrusion 244A can be formed on the cover part 200 as a pressure contact part for applying pressure to the part where the flexibility imparting groove 234 is formed.

[0245] Meanwhile, in order to improve the sealing strength of the container, it is preferable to relatively increase the contact area between the upper end portion of the container inlet 20 and the cover part 200. In particular, it is preferable that the plurality of contact areas are formed based on a path leading from the outside of the container to the inside of the container, rather than being connected to each other.

[0246] As a first example, as shown in FIG. 30A, in addition to the inner ring 290 presented in the first embodiment and the inner protrusion 21 that contacts the outer surface of the inner ring 290, the cover part 200 may further be formed with an auxiliary inner ring 280 that is in close contact with the upper end portion of the container inlet 20.

[0247] The auxiliary inner ring 280 may be formed between the upper end portion of the container inlet 20 and the inner ring 290, protruding downward from the cover part 200, particularly from the bottom surface of the cover part 200.

[0248] At this time, it is preferable that the auxiliary inner ring 280 is formed shorter than the vertical length of the inner ring 290 in order to prevent interference with the inner ring 290 .

[0249] Preferably, the auxiliary inner ring 280 is formed to contact the upper end portion of the container inlet 20 when the cover part 200 is coupled to the container inlet 20 .

[0250] For this reason, it is preferable that the end face of the upper end portion of the container inlet 20 is curved, and an inner peripheral auxiliary protrusion 122 can be formed in which the inner peripheral surface of the upper end portion of the container inlet 20 protrudes toward the inner peripheral surface of the auxiliary inner ring 280.

[0251] As a second example, as shown in FIG. 30B, in the structure shown in FIG. 39A, at least one surface where the auxiliary inner ring 280 and the upper end portions of the container inlet 20 come into contact with each other may be formed as an inclined surface 180, 241A.

[0252] On the other hand, in the first and second examples, the auxiliary inner ring 280 may be positioned between the upper end of the container inlet 20 and the wall portion 25 instead of between the upper end of the container inlet 20 and the inner ring 290, and the corresponding configuration may of course be formed symmetrically.

[0253] As a third example, as shown in FIG. 30C, the flexibility-imparting groove 231 can be further formed in the structure of FIG. 30B.

[0254] Here, an auxiliary protrusion 122 as shown in FIG. 30A may be formed on the inner circumferential surface of the container inlet 20.

[0255] As a fourth example, as shown in FIG. 30D, the flexibility groove 231 can be further formed in the structure of FIG. 30A.

[0256] As a fifth example, as shown in FIG. 30E, in the structure of FIG. 30D, the container inlet 20 can be formed to be inclined from the upper end to the inner circumferential protrusion 21.

[0257] Specifically, the container inlet 20 can have an inner circumferential surface that is inclined in a direction in which the inner diameter decreases from the upper end to the inner circumferential protrusion 21 .

[0258] Due to the above-mentioned structure, when the cover part 200 is connected to the container inlet 20, when the cover part 200 is lowered relative to the container inlet 20, the outer surface of the auxiliary ring 280 can come into close contact with each other between the upper end of the container inlet 20 and the inner protrusion part 21.

[0259] <Fifth Example> Meanwhile, the sealing force of the container can be improved by intentionally increasing the area that comes into close contact with the cover part 200 and the container inlet 20 when they are combined, and various embodiments are possible.

[0260] In particular, if the contact portion between the upper end portion of the container inlet 20 and the cover portion 200 is improved, the sealing force of the container can be improved.

[0261] As shown in Figures 31A and 31B, in the container according to the fifth embodiment of the present invention, the container inlet 20 has a central groove 220 formed by an inner upper end portion 222 and an outer upper end portion 221, and the cover part 200 can form an inner inclined surface 241 and an outer inclined surface 242 that contact the inner part of the inner upper end portion 222 and the outer part of the outer upper end portion 221.

[0262] Specifically, the container inlet 20 may have an upper end portion formed with an inner upper end portion 222 and an outer upper end portion 221 to form a groove 220 in the center.

[0263] At this time, the inner portion of the inner upper end portion 222 and the outer portion of the outer upper end portion 221 may be formed as curved surfaces so as to be in close contact with the inner inclined surface 241 and the outer inclined surface 242 .

[0264] It is preferable that the side wall portions of the groove 220 are formed to slope upward so that the upper ends of the inner upper end portion 222 and the outer upper end portion 221 can easily deform in the direction that narrows the width of the groove 220, i.e., so that the inner upper end portion 222 and the outer upper end portion 221 can easily shrink relative to each other.

[0265] In other words, the inner upper end portion 222 and the outer upper end portion 221 preferably have a V-shape.

[0266] Meanwhile, the cover part 200 has an inner inclined surface 241 and an outer inclined surface 242 that contact the inner part of the inner upper end part 222 and the outer part of the outer upper end part 221, respectively.

[0267] The inner inclined surface 241 and the outer inclined surface 242 are formed on the cover part 200 so as to contact the inner part of the inner upper end part 222 and the outer part of the outer upper end part 221, and may have various structures.

[0268] As an example, the inner inclined surface 241 can be formed as part of an inner ring 290, as shown in Figures 31A and 31B.

[0269] Furthermore, if an auxiliary inner ring 280 is provided, the inner inclined surface 241 can be formed as a part of the auxiliary inner ring 280 .

[0270] Meanwhile, the cover part 200 may have an inner contact ring 960 and an outer contact ring 950 formed with opposing grooves 292 so that the upper end portion of the container inlet 20 may be at least partially inserted therein, as shown in FIG. 31B.

[0271] The inner contact ring 960 and the outer contact ring 950 are configured to be formed in the cover part 200 so as to form opposing grooves 292 into which the upper end portion of the container inlet 20 is at least partially inserted, and various configurations are possible.

[0272] For example, the inner contact ring 960 and the outer contact ring 950 may be formed to extend downward from the bottom surface of the cover part 200 .

[0273] At this time, it is preferable that the inner contact ring 960 and the outer contact ring 950 have a curved surface at the portion that comes into contact with the upper end portion of the container inlet 20 .

[0274] It is preferable that the sidewalls of the opposing grooves 292 are formed with an upward slope so that the lower ends of the inner contact ring 960 and the outer contact ring 950 can easily deform in the direction that widens the width of the opposing grooves 292, i.e., so that the inner contact ring 960 and the outer contact ring 950 can easily deform in the direction that widens the width of each other.

[0275] In other words, the inner contact ring 960 and the outer contact ring 950 preferably have an inverted V shape facing downwards.

[0276] Meanwhile, the upper end portion of the container inlet 20 is preferably formed sharply so as to be easily inserted into the opposing grooves 292 formed by the inner contact ring 960 and the outer contact ring 950 .

[0277] As shown in FIG. 31B, the upper end portion of the container inlet 20 may be formed with inclined surfaces 961 and 951 that extend inward and outward from the uppermost end so that the container inlet 20 can be easily inserted into the opposing groove 292.

[0278] <Sixth Example> On the other hand, referring to the above-mentioned embodiment, as a means of increasing the sealing force of the container, it is preferable to increase the contact area where the cover portion 200 and the container inlet 20 come into contact with each other, particularly to increase the contact area between the upper end portion of the container inlet 20 and the cover portion 200 relatively significantly.

[0279] Here, it is preferable that the plurality of contact portions are formed based on a path leading from the outside of the container to the inside of the container, rather than being connected to each other.

[0280] In particular, the formation of the plurality of contact portions can be achieved by modifying the structure of the cover part 200 and the container inlet 20, and can be realized by forming inclined surfaces with various angles and structures, flexibility-imparting grooves, and the like.

[0281] Furthermore, the structures of the cover part 200 and the container inlet 20 can be interchanged to change the structure of the plurality of contact parts.

[0282] Hereinafter, various modifications of the container inlet 20 for forming the plurality of contact portions based on the path from the outside of the container to the inside of the container will be described.

[0283] As shown in FIG. 32A, the container inlet 20 may have an inner upper end portion 222 and an outer upper end portion 221 formed around the groove 220 at the upper end portion.

[0284] Here, the groove 220 is formed close to the inside or outside, so that either the inside upper end portion 222 or the outside upper end portion 221 can be formed to be narrower than the other so that it can be easily deformed by contact with the cover part 200.

[0285] Furthermore, the heights of the inner upper end portion 222 and the outer upper end portion 221 may be the same or different.

[0286] FIG. 32A shows a case where the width of the inner upper end portion 222 is smaller than the width of the outer upper end portion 221. In FIG. The groove 220 may be formed so that its width increases upward.

[0287] FIG. 32B is a variation of the container inlet 20 shown in FIG. 32A.

[0288] The container inlet 20 shown in FIG. 32B may be formed so that the height of the inner upper end portion 222 is lower than the height of the outer upper end portion 221.

[0289] Furthermore, a minute ring protrusion 229 may be formed on the inner circumferential surface of the container inlet 20 to increase the contact area with the cover part 200 .

[0290] FIG. 32C is a variation of the container inlet 20 shown in FIG. 32A.

[0291] The container inlet 20 shown in FIG. 32C may further be formed with a central protruding upper end portion 225 that protrudes upward from the recessed groove 220 of FIG. 32A.

[0292] In particular, the central protruding upper end portion 225 may be formed higher than the inner upper end portion 222 and the outer upper end portion 221, so that the groove 220 may be divided into two grooves 220A and 220B.

[0293] At this time, it is preferable that the cover part 200 coupled to the container inlet 20 has a ring-shaped groove formed therein into which the central protruding upper end part 225 is inserted.

[0294] FIG. 32D is a variation of the container inlet 20 shown in FIG. 32A.

[0295] The container inlet 20 shown in Figure 32D has an inner upper end portion 222 that is higher and narrower than the outer upper end portion 221, and a step portion 226 that is smaller than the inner upper end portion 222 and the outer upper end portion 221 can be formed on the inside.

[0296] FIG. 32E is a variation of the container inlet 20 shown in FIG. 32A.

[0297] The container inlet 20 shown in FIG. 32E is the opposite of that shown in FIG. 32A, and the outer upper end portion 221 may be formed to be narrower than the inner upper end portion 222.

[0298] Figures 32A and 32D show a structure in which the relatively narrow inner upper end portion 222 or outer upper end portion 221 is formed in a position where the blocking structure can be deformed by pressurizing the cover part 200 or filling it with hot contents, and the container inlet 20 can have all or part of the structure shown in Figures 32F and 32G in addition to the structure shown in Figures 28A and 28C of the third embodiment.

[0299] Alternatively, the flexibility grooves may be formed on the outer or inner circumferential surface of the container inlet 20 near the top end thereof, as shown in FIG. 32F.

[0300] That is, as shown in FIG. 32F, the flexibility groove 232 may be formed on the outer periphery of the container inlet 20 .

[0301] At this time, in order to form the flexibility groove 232 that is pressed against the cover part 200, a ring-shaped flexibility protrusion 230 is formed on the outer peripheral surface of the container inlet 20, and the flexibility groove 232 is formed in a concave shape from the top to the bottom of the flexibility protrusion 230, thereby forming the flexibility groove 232.

[0302] Here, it goes without saying that the flexibility-imparting groove 232 may be relatively formed by a groove-forming protrusion ring 238 extending upward.

[0303] As another example, as shown in FIG. 32G, flexibility grooves 235 can be formed in the inner periphery of container inlet 20.

[0304] At this time, in order to form the flexibility groove 235 that is pressed against the cover part 200, a ring-shaped inner flexibility part 250 is formed on the inner peripheral surface of the container inlet 20, and the flexibility groove 232 is formed concavely from the top to the bottom in the inner flexibility part 250, thereby forming the flexibility groove 235.

[0305] Here, it goes without saying that the flexibility-imparting groove 235 may be relatively formed by a groove-forming protrusion ring 239 extending upward.

[0306] Meanwhile, the cover part 200 has a structure such as an inclined surface or an inner ring for pressing the groove forming protrusion ring 239 .

[0307] Hereinafter, various modifications of the cover part 200 will be described in addition to or separately from the container inlet 20 in order to form a plurality of contact portions based on the path from the outside of the container 30 to the inside of the container 30.

[0308] The cover portion 200 shown in FIG. 33A can have the structure of the container cap shown in FIG. 27B or FIG. 28A.

[0309] The cover part 200 shown in FIG. 33B is a modification of the cover part 200 shown in FIG. 33A, and shows a case where the gap between the contact ring 950 and the inner ring 290 is formed relatively small.

[0310] The end of the contact ring 950 can be positioned lower than the inner ring 290 .

[0311] Here, the container inlet 20 may have an inclined surface, a protruding ring, or the like formed at a portion that comes into contact with the contact ring 950 .

[0312] 33C shows a modification of FIG. 33A in which the contact ring 950 can be formed to protrude from the inner circumferential surface of the side wall portion 25 instead of the bottom surface of the cover portion 200. In FIG.

[0313] Here, the container inlet 20 may have an inclined surface, a protruding ring, or the like formed at a portion that comes into contact with the contact ring 950 .

[0314] 34A to 34C show examples in which the cover part 200 and the container inlet 20 having various structures are combined.

[0315] FIG. 34A shows an example of a structure in which a cover part 200 is coupled to the structure of the container inlet 20 shown in FIG. 32G, and is similar to the structure shown in FIG. 28C, so detailed description will be omitted.

[0316] Figure 34B shows a structure in which a cover part 200 having a structure similar to that shown in Figure 29A is joined to a container inlet 20 that is modified from the container inlet 20 of Figure 32A. Detailed explanations similar to those of the structure shown in Figure 29A will be omitted.

[0317] The container inlet 20 shown in Figure 34C has an inner upper end portion 222, an outer upper end portion 221, and an auxiliary upper end portion 220d at its upper end, and the cover part 200 can have an insertion protrusion ring 199 that is inserted into the groove 220 formed by the upper end portion 222 and the outer upper end portion 221.

[0318] Meanwhile, the container inlet 20 has an auxiliary upper end portion 220d formed inside the inner upper end portion 222, which is lower in height than the inner upper end portion 222 and the outer upper end portion 221, and together with the inner upper end portion 222, an additional groove 220C can be formed.

[0319] The above is merely a description of some of the preferred embodiments that can be realized by the present invention, and as is well known, the scope of the present invention should not be interpreted as being limited to the above-mentioned embodiments, and it can be said that the technical ideas of the present invention described above and technical ideas based on them are all included in the scope of the present invention.
