[0069] Hereinafter, a container cap and a container (container assembly) combined with the container cap according to the present invention will be described below with reference to the drawings.

[0070] The container 30 is used as a container for storing granular or powdery contents, and can be of any structure as long as it can store the contents, and the container opening 20 can also be of any shape and structure as long as it is formed to be combined with the container cover 10.

[0071] Furthermore, considering the binding force of the container cover 10 of the present invention, the container 30 preferably stores granular or powdery contents, but of course, liquid contents may also be stored.

[0072] In addition, in order to prevent the contents from deteriorating before use, the container 30 is a sealable container 30 that is combined with a sealing member (not shown) at the opening of the container mouth 20 .

[0073] The main body 100 is a structure that is coupled to the container mouth 20 of the container 30 for storing the contents and is opened at the upper side. Various structures may be adopted depending on the coupling structure with the container mouth 20 .

[0074] As an example, the body portion 100 may have a ring shape corresponding to the horizontal cross-sectional shape of the container mouth 20 , such as a circular shape, an elliptical shape, a polygonal shape, etc.

[0075] In addition, the main body 100 may be threadedly coupled to an external thread portion formed on an outer circumferential surface of the container mouth 20 . To this end, an internal thread portion may be formed on an inner circumferential surface of the main body 100 to be threadedly coupled to the external thread portion of the container mouth 20 .

[0076] The cover 200 is a structure that is combined with the main body 100 to open and close the upper opening of the main body 100 , and may have various structures.

[0077] In particular, the cover portion 200 may have various structures depending on the structure of the cover portion 200 coupled with the main body portion 100 .

[0078] As an example, the cover 200 is combined with the main body 100 in a completely detachable state, that is, a two-piece structure, or as Figure 4c As shown, the hinge portion 530 can be hinged when it is separated from the main body 100, that is, it is a one-piece structure.

[0079] The hinge portion 530 is a structure that connects the cover portion 200 and the main body portion 100 as a whole and allows the cover portion 200 to hinge when the cover portion 200 is separated from the main body portion 100, and various structures may be adopted.

[0080] In addition, considering the bonding force with respect to the main body 100 before unsealing, the cover 200 may be connected to the main body 100 up and down through a dividing line (not shown) or a plurality of bridges (not shown).

[0081] For this structure, the hinge portion 530 may be integrally formed together with the cover portion 200 and the main body portion 100 during injection molding.

[0082] On the other hand, the cover 200 can be combined with the main body 100 in a state where the cover 200 is detachably combined with the main body 100 except for the separation part 300 described later, or in a state where the cover 200 is detachably combined with the main body 100 except for the separation part 300 and the hinge part 530 described later.

[0083] At this time, in order to maintain the state of being combined with the main body 100 when the container 30 is not in use, the cover 200 can be combined with the main body 100 through various existing structures, thereby closing the upper opening of the main body 100.

[0084] Then, the cover part 200 may be combined with a part of the upper end portion of the container mouth 20 in addition to being combined with the main body part 100 .

[0085] At this time, the cover 200 is coupled to the upper end of the cover 200 so as to be separated from the main body 100 without rotation with respect to the container mouth 20 .

[0086] Furthermore, in order to prevent the contents from being deteriorated when combined with the upper end of the container mouth 20, the cover 200 is preferably combined with the container mouth 20 using an isolation structure described later.

[0087] On the other hand, the container cap 10 of the present invention may be provided with a structure for confirming the use traces such as opening in the initial state of being coupled to the container mouth 20 .

[0088] Specifically, the container cover 10 of the present invention also includes a separation portion 300, which is connected to a first component as any one of the main body 100 and the cover 200 through a first connecting portion 510, and is detachably connected to a second component as the remaining one of the main body 100 and the cover 200 through a second connecting portion 520.

[0089] The separation part 300 is a structure that is connected to a first component of any one of the main body 100 and the cover 200 through a first connection part 510 and is detachably connected to a second component of the remaining one of the main body 100 and the cover 200 through a second connection part 520, and can adopt various structures.

[0090] The first connecting portion 510 is a structure that connects the first component, such as the cover 200 and the separation portion 300 described later, into one body. Considering the movement of the separation portion 300 after separation, it is preferably formed to be thinner (thin film) than the side thickness of the cover 200 and the main body 100.

[0091] Then, the first connection portion 510 may be formed with various widths, such as a circumferential width that is smaller than or equal to a width of the separation portion 300 .

[0092] The second connection portion 520 is a structure for detachably connecting the second member, for example, the main body 100 and the separation portion 300 described later, and may adopt various structures.

[0093] In particular, the second connection portion 520 is characterized in that the cover portion 200 can be separated from the main body portion 100 by separating the second connection portion 520 through the operation of a user.

[0094] Specifically, the second connection portion 520 may be any structure as long as it is a detachable structure that can be easily separated or cut by user operation, for example, it may be formed by a cutting groove or a plurality of bridges so as to be easily separated by user operation.

[0095] On the other hand, the second connection portion 520 may be coupled to various structures and positions according to the formation structure of the separation portion 300 and the second component, such as the main body 100 .

[0096] As an example, the second connection portion 520 may be connected horizontally and / or vertically along the edge of the separation portion 300 .

[0097] In addition, the second connection portion 520 can be connected to the separation portion 300 by being combined with the separation portion 300 and the second component, for example, the outer peripheral surface of the main body 100 .

[0098] In addition, the second connection portion 520 may be detachably coupled to the first component, such as the cover 200 , in addition to the second component, such as the main body 100 .

[0099] The separation part 300 is a structure integrally connected to the first component and detachably connected to the second component. Various embodiments can be realized according to the combination and separation methods with the cover part 200 and the main body part 100.

[0100] At this time, if Figures 2 to 20b As shown, the separation portion 300 can connect the main body portion 100 and the cover portion 200 in an upward and downward direction.

[0101] In addition, the first member, for example, the cover 200, preferably has a fixing portion 400 for fixing the separating portion 300 after the separating portion 300 is separated from the second member.

[0102] The fixing part 400 is formed on a first member, for example, the cover 200 and is fixed after the separation part 300 is separated from the second member. Various structures may be adopted depending on the coupling structure with the separation part 300 .

[0103] As an example, Figures 2 to 20b As shown, the separation part 300 is inserted and combined with the fixing part 400 and can be fixed on the fixing part 400 .

[0104] At this time, if Figures 2 to 17b As shown, the separation portion 300 can be combined with the fixing portion 400 by folding in an upward and downward direction through the first connection portion 510.

[0105] Then, the fixing portion 400 may include one or more second insertion and coupling portions 420 formed on the outer peripheral surface of the first member and engaged with one or more first insertion and coupling portions 320 disposed on the separation portion 300 .

[0106] In addition, if Figures 18a to 20b As shown, the separation part 300 can be combined with the fixing part 400 by moving in the up-down direction.

[0107] On the other hand, the fixing portion 400 may include one or more second insertion and coupling portions 420 formed on the outer peripheral surface of the first member and engaged with one or more first insertion and coupling portions 320 disposed on the separation portion 300 .

[0108] The first insertion joint portion 320 and the second insertion joint portion 420 are formed by Figure 2 to Figure 21c The structures shown are combined by insertion and bonding, and various structures such as protrusions, grooves, etc. can be adopted according to the structures of mutual insertion and bonding.

[0109] On the other hand, the separation portion 300 can connect the main body portion 100 and the cover portion 200 in a circumferential direction.

[0110] Then, the separating portion 300 is separated from the second member along the circumferential direction and can be fixedly coupled to the fixing portion 400 formed on the first member.

[0111] The connection structure described above can be arranged and connected in a circumferential direction. Figures 2 to 20b The structure shown is implemented in an up-down direction rather than a down-down direction.

[0112] As another example, Figures 21a to 21c As shown, the separation part 300 has a strip structure connected between the first component and the second component through a plurality of bridges. After being separated from the second component, the separation part 300 can be inserted into and fixed to the fixing part 400 formed on the outer circumference of the second component.

[0113] On the other hand, the separation part 300 can be coupled to the fixing part 400 at various angles, such as being rotated 90° upward or 180° upward.

[0114] In addition, the coupling structure of the separation part 300 and the fixing part 400 may be any structure as long as it is a protruding part and a structure in which the protruding part is inserted into the corresponding protruding part.

[0115] In particular, the first action of pushing the separating part 300 upward to be coupled to the fixing part 400 and the first action of pushing the coupled separating part 300 and the fixing part 400 upward to form a Figure 5dThe secondary action of opening to the upper side is achieved in a one-action-one-touch manner, thus having the advantage of facilitating the unsealing action of the container 30 .

[0116] In the following, regarding the structure of the separation unit 300 , considering the convenience of separating the cover unit 200 , an embodiment of the separation unit 300 is described with the cover unit 200 as the first component and the main body 100 as the second component.

[0117] First embodiment ( Figure 2 to Figure 5c )

[0118] A first embodiment of the coupling structure of the separation part and the fixing part is described below.

[0119] like Figure 2 , Figures 4a to 4c As shown, the separation portion 300 as the first insertion joint portion 320 can form a bottom 301 and a pair of protrusions 310, wherein the bottom 301 protrudes from the cover portion 200 toward the main body 100, and the pair of protrusions 310 protrude in the radial direction and are formed at intervals along the circumferential direction.

[0120] At this time, the separation portion 300 is connected to the main body portion 100 through a second connection portion 520 consisting of a cutting line or a plurality of bridges (not shown).

[0121] Then, the main body 100 is recessed to form a groove 130 having a shape corresponding to the front shape of the separation part 300 .

[0122] Then, the fixing portion 400 may protrude from the outer circumferential surface of the cover portion 200 to form one or more second insertion joints, and the second insertion joints 420 have a width corresponding to the first insertion joint 320 formed by the pair of protrusions 310, that is, the groove.

[0123] The second insertion coupling portion 420 is a protrusion having a width corresponding to the groove formed by the pair of protrusions 310 and is formed on the outer peripheral surface of the cover 200 , and various structures may be adopted.

[0124] On the other hand, the separation portion 300 and the fixing portion 400 may be formed at a position opposite to the hinge portion 530, and the separation portion 300 and the fixing portion 400 combined with each other may be used as a handle to open the container 30 by separating the cover portion 200 from the main body 100 through the operation of a user.

[0125] At this time, the separation part 300 can be turned upward by the operation of the user. Figure 3 , Figure 5a to Figure 5d As shown, the second connection part 520 is cut off, the first connection part 510 is turned upward, and then the separation part 300 and the fixing part 400 are connected to each other.

[0126] The separation part 300 and the fixing part 400 combined with each other as described above can separate the cover part 200 from the main body part 100 by the operation of the user, and can open the container 30 by a single action, a so-called one-touch action.

[0127] Second embodiment ( Figures 6 to 9c )

[0128] Hereinafter, a second embodiment of the separation unit and the fixing unit will be described.

[0129] Compared with the first embodiment, the structure of the second embodiment is different in the combination structure with the fixing portion.

[0130] First, if Figure 6 , Figures 8a to 8c As shown, the second insertion and coupling portion 420 of the fixing portion 400 may be composed of one or more protrusions, and the protrusions are inserted into the insertion grooves 321 formed in the first insertion and coupling portion 320 of the separating portion 300 .

[0131] The protrusions are structures inserted into the insertion grooves 321 formed in the first insertion and coupling part 320 of the separation part 300 , and can be formed at corresponding positions in a number corresponding to the number of the insertion grooves 321 formed in the first insertion and coupling part 320 of the separation part 300 .

[0132] Then, the first insertion coupling portion 320 of the separation portion 300 may be formed by an embedded column, which is protruded from the bottom 301 and has an embedded groove 321 embedded in the protruding portion formed in the fixing portion 400, wherein the bottom 301 is protruded from the cover portion 200 to the main body portion 100.

[0133] The embedding column may have various structures as a structure protruding from the bottom 301 and having an embedding groove 321 embedded in a protruding portion formed in the fixing portion 400 , wherein the bottom 301 is protruding from the cover 200 toward the main body 100 .

[0134] In particular, Figure 8a As shown, the embedding column is preferably formed such that the end portion is inclined in the circumferential direction so that the separating part 300 can be folded upward to facilitate the insertion and fixing of the protruding part of the fixing part 400 .

[0135] More specifically, a pair of the embedded pillars may be formed, in which case the ends are formed to be inclined downward in directions toward each other.

[0136] On the other hand, the separation portion 300 is connected to the main body portion 100 through a second connection portion 520 composed of a cutting line or a plurality of bridges (not shown).

[0137] Then, the main body 100 is recessed to form a groove 130 corresponding to the front shape of the separation part 300 .

[0138] On the other hand, the separation portion 300 and the fixing portion 400 may be formed at a position opposite to the hinge portion 530, and the separation portion 300 and the fixing portion 400 combined with each other may be used as a handle to open the container 30 by separating the cover portion 200 from the main body 100 through the operation of a user.

[0139] At this time, the separation part 300 can be turned upward by the operation of the user, and the second connection part 520 is cut off at this time, thereby separating the separation part 300 from the main body 100.

[0140] Then, if Figure 7 , Figures 9a to 9c As shown, for the separation portion 300 , the first connection portion 510 is folded upward, and the separation portion 300 is combined and fixed to the fixing portion 400 .

[0141] Third embodiment ( Figures 10a to 11c )

[0142] A third embodiment of the coupling structure of the separation portion and the fixing portion will be described below.

[0143] Compared with the first and second embodiments, the coupling structure of the separation portion and the fixing portion in the third embodiment is a modified example of the insertion coupling structure.

[0144] like Figures 10a to 10c As shown, the separation portion 300 includes a bottom portion 301 and a first insertion and coupling portion 320 . The bottom portion 301 is formed to protrude from the cover portion 200 toward the main body portion 100 . The first insertion and coupling portion 320 is a protrusion formed to protrude from the upper end portion of the bottom portion 301 .

[0145] The bottom portion 301 is a structure that is detachably coupled to the main body 100 via the second connection portion 520 , and may have various shapes.

[0146] At this time, in order to form the bottom 301 , the main body 100 is recessed to form a groove 130 corresponding to the front shape of the separation part 300 .

[0147] At this time, if Figures 10a to 11c As shown, the portion where the groove 130 is formed may be formed with an inclined portion 140 , and the inclined portion 140 faces the bottom surface of the separating portion 300 corresponding to the lower end of the separating portion 300 , so as to easily separate the separating portion 300 .

[0148] The inclined portion 140 is inclined toward the bottom surface of the separating portion 300 corresponding to the lower end of the separating portion 300 , so that the user can hook the lower end of the separating portion 300 with his fingers to make the separating portion 300 easily separated.

[0149] On the other hand, the separation part 300 is connected to the cover part 200 through the first connection part 510 , and the first connection part 510 can be connected in various structures.

[0150] That is, different from the first embodiment and the second embodiment, a pair of the first connecting parts 510 are provided, so that the separation part 300 and the cover part 200 can be connected as one body at both sides.

[0151] Then, the first insertion coupling part 320 may be formed by a protrusion protruding from the upper end of the bottom 301 , and one first insertion coupling part 320 may be protrudingly formed at the center.

[0152] On the other hand, the fixing part 400 combined with the separating part 300 may be formed as a groove inserted into the first inserting and coupling part 320 , thereby forming a second inserting and coupling part 420 .

[0153] At this time, the fixing part 400 may be formed with a groove as a structure that is inserted into the remaining portion of the upper end of the bottom part 301 .

[0154] On the other hand, as described above, the separation portion 300 and the fixing portion 400 are located opposite to the hinge portion 530, and the separation portion 300 and the fixing portion 400 combined with each other can be used as a handle to open the container 30 by separating the cover portion 200 from the main body 100 through the operation of the user.

[0155] Fourth embodiment ( Figures 12a to 13b )

[0156] A fourth embodiment of the coupling structure of the separation portion and the fixing portion will be described below.

[0157] Compared with the first embodiment, the coupling structure of the separation portion and the fixing portion of the fourth embodiment is a modified example of the second insertion coupling portion 420 constituting the fixing portion 400 .

[0158] exist Figure 2 to Figure 5c In the case of the coupling structure of the separation part and the fixing part of the first embodiment shown, the protrusion of the second insertion coupling part 420 constituting the fixing part 400 is flipped over during the distribution process or due to the user's carelessness, so that the cover part 200 can be separated from the main body part 100.

[0159] According to this, if Figures 12a to 13b As shown, in the structure of the first embodiment, the second insertion coupling portion 420 of the fixing portion 400 may be formed as a thin film.

[0160] When the second insertion joint part 420 of the fixing part 400 is constructed as a thin film, even if the second insertion joint part 420 of the fixing part 400 is forced upward due to the circulation process or the user's inattention, only the second insertion joint part 420 of the fixing part 400 is flipped upward, thereby solving the problem of separating the cover part 200 from the main body part 100.

[0161] Fifth embodiment ( Fig.14a and Fig.14b )

[0162] Hereinafter, a fifth embodiment of the coupling structure of the separation portion and the fixing portion will be described.

[0163] Compared with the first embodiment, the coupling structure of the separation portion and the fixing portion of the fifth embodiment is a modified example of the first insertion coupling portion 320 and the second insertion coupling portion 420 .

[0164] The first insertion coupling part 320 is formed of a protrusion protruding from the central portion of the bottom 301 , and the second insertion coupling part 420 may be formed of a pair of groove forming protrusions having a groove formed therein to insert the protrusion of the first insertion coupling part 320 .

[0165] As in Fig.14a and Fig.14b In the variation of the structure shown, the first connection part 510 is folded and inserted into the groove formed by a pair of groove-forming protrusions, and the bottom 301 is stuck at the upper end of the groove-forming protrusion, thereby combining the separation part 300 and the fixing part 400.

[0166] Sixth embodiment ( Figures 15a to 16b )

[0167] A sixth embodiment of the coupling structure of the separation portion and the fixing portion will be described below.

[0168] Compared with the first embodiment, the coupling structure of the separation portion and the fixing portion of the sixth embodiment is a modified example of the first insertion coupling portion 320 and the second insertion coupling portion 420 .

[0169] The first insertion and coupling portion 320 may be formed of a groove formed in the bottom portion 301 , and the second insertion and coupling portion 420 may be formed of an insertion protrusion inserted into the groove formed in the first insertion and coupling portion 320 .

[0170] Specifically, when the bottom portion 301 is turned upward by a user, the first connection portion 510 is folded, and the bottom portion 301 is rotated upward with reference to the first connection portion 510 .

[0171] Then, the bottom portion 301 is rotated toward the second insertion coupling portion 420 , and the insertion protrusion of the second insertion coupling portion 420 is inserted into and coupled to the groove formed in the bottom portion 301 .

[0172] At this time, in order to facilitate the combination of the first insertion joint 320 and the second insertion joint 420, one or more guide protrusions 440 can be formed in the outer peripheral surface of the cover 200 at a portion corresponding to the outer contour edge of the bottom 301 to guide the combination of the first insertion joint 320 and the second insertion joint 420.

[0173] The guide protrusion 440 is formed on the outer peripheral surface of the cover 200 to guide the first insertion joint part 320 and the second insertion joint part 420 to be joined at a portion corresponding to the outer edge of the bottom 301 , and various structures may be adopted according to the front shape of the bottom 301 .

[0174] As an example, when the front shape of the bottom portion 301 is formed into a right-angled quadrilateral, the front shape of the guide protrusion 440 corresponding to the vertex of the shape may be formed into an "L" shape.

[0175] Seventh embodiment ( Fig.17a and Fig.17b )

[0176] A seventh embodiment of the coupling structure of the separation portion and the fixing portion will be described below.

[0177] Compared with the first embodiment, the coupling structure of the separation portion and the fixing portion of the seventh embodiment is a modified example of the first insertion coupling portion 320 and the second insertion coupling portion 420 .

[0178] The first insertion coupling portion 320 is composed of three groove forming protrusions forming two grooves in a horizontal direction, and the second insertion coupling portion 420 may be composed of two protrusions to be inserted into the two grooves formed by the three groove forming protrusions.

[0179] With the above-described structure, when the separation unit 300 separates the main body 100 and turns upward, the three grooves formed on the bottom 301 form projections that face the two projections.

[0180] Then, the two protrusions of the second insertion and coupling portion 420 are inserted and coupled to the two grooves formed by the three groove-forming protrusions, and thus the separation portion 300 is fixedly coupled to the fixing portion 400 .

[0181] Eighth embodiment ( Fig.18a and Fig.18b )

[0182] Next, an eighth embodiment of the coupling structure of the separation portion and the fixing portion will be described.

[0183] Compared with the first embodiment, the coupling structure of the separation part and the fixing part of the eighth embodiment is a modified example of the moving structure of the first insertion coupling part 320 and the coupling structure of the first insertion coupling part 320 and the second insertion coupling part 420 .

[0184] First, if Figures 18a to 20b As shown, the separation portion 300 , namely the first insertion and coupling portion 320 , has a feature of being coupled to the fixing portion 400 by moving in an upward and downward direction.

[0185] To this end, the first insertion coupling portion 320 may adopt various structures according to the insertion coupling structure of the second insertion coupling portion 420 .

[0186] As an example, the first insertion coupling portion 320 may include a head portion 323 and an extension portion 324 , and the extension portion 324 is smaller in width than the head portion 323 .

[0187] The head 323 may have any structure as long as the width thereof is greater than the width of the groove so as to maintain the stuck state in the groove formed by a pair of protrusions forming the second insertion joint 420 described later.

[0188] Particularly, the head 323 preferably has a wedge shape to maintain a stuck state by a groove formed by a pair of protrusions.

[0189] The extension portion 324 is a portion extending downward from the head portion 323 , and may be located between the grooves formed by the pair of protrusions after the head portion 323 passes through the grooves formed by the pair of protrusions.

[0190] On the other hand, in order to prevent the head 323 from excessively moving, the first insertion coupling portion 320 may extend horizontally to form a locking portion 325 , and the locking portion 325 is locked by a pair of protrusions, thereby preventing the head 323 from excessively moving.

[0191] The locking portion 325 is a structure that is locked on a pair of protrusions to prevent the head 323 from excessively moving, and various structures can be adopted.

[0192] Furthermore, the locking portion 325 may extend upward to form an upper extension portion 326 , so as to form, together with the extension portion 324 , grooves into which the pair of protrusions are inserted respectively.

[0193] On the other hand, the second connection portion 520 may of course also be formed between the bottom surface of the separation portion 300 and the outer peripheral surface of the main body 100 .

[0194] In addition, in order to form the separation part 300 , it is not necessary to form the groove 130 corresponding to the front shape of the separation part 300 in the body part 100 .

[0195] On the other hand, the second insertion coupling portion 420 constituting the fixing portion 400 may be composed of a pair of protrusions, which form a groove smaller than the horizontal width of the head portion 323 , thereby being able to insert and clamp the head portion 323 .

[0196] The pair of insertion protrusions may be configured as a structure that forms a groove smaller than the horizontal width of the head 323 and into which the head 323 may be inserted and clamped, and various structures may be adopted.

[0197] Ninth embodiment ( Figures 19a to 20b )

[0198] A ninth embodiment of the coupling structure of the separation portion and the fixing portion will be described below.

[0199] Compared with the second embodiment, the coupling structure of the separation portion and the fixing portion of the ninth embodiment is a modified example of the second insertion coupling portion 420 .

[0200] Specifically, the second insertion joint 420 may include: a pair of first protrusions to keep the head 323 inserted before the separation part 300 is separated from the main body 100; and a pair of second protrusions to move the head 323 upward after the separation part 300 is separated from the main body 100, so that the head 323 passes through and is stuck.

[0201] Tenth embodiment ( Figures 21a to 21c )

[0202] A ninth embodiment of the coupling structure of the separation portion and the fixing portion will be described below.

[0203] The separation part and the fixing part of the ninth embodiment are connected in a circumferential direction. Figures 2 to 20b The structure shown is not an embodiment of an up-and-down configuration.

[0204] Specifically, if Figures 21a to 21c As shown, the separation portion 300 has a strip structure connected to the cover portion 200 and the main body portion 100 through multiple bridges (not shown), and after being separated from the cover portion 200 and the main body portion 100, it can be inserted into and fixed to the fixing portion 400 on the outer peripheral surface of any one of the cover portion 200 and the main body portion 100.

[0205] At this time, at least a portion of the outer circumferential surfaces of the cover portion 200 and the fixing portion 400 may be cut in the portion where the separation portion 300 is located to provide the separation portion 300 .

[0206] Then, in order to facilitate the separation of the separation part 300, a separation handle for the user to grasp may be formed at the end portion.

[0207] On the other hand, the separation portion 300 is integrally connected to one side of the cover portion 200 and the main body portion 100 where the fixing portion 400 is formed through the first connection portion 510 so that the end portion close to the fixing portion 400 can be folded in a circumferential direction.

[0208] The fixing portion 400 may have any structure as long as it is formed on one side of the cover portion 200 and the main body portion 100 connected to the separating portion 300 and can fix the separating portion 300 .

[0209] As an example, considering the separating portion 300 of a stripe structure, the fixing portion 400 may have a structure formed with a through hole inserted in a circumferential direction.

[0210] On the other hand, the cover 200 can be hingedly connected to the main body 100 via the hinge 530. In this case, in order to allow the user to easily separate the cover 200 from the main body 100, a handle 580 can be formed at a position facing the hinge 530.

[0211] Function of handle and injection molding

[0212] On the other hand, in the container cover 10 of the present invention, at least one of the separation portion 300 and the fixing portion 400 is located opposite to the hinge portion 530, and the separation portion 300 and the fixing portion 400 combined with each other can be used as a handle to open the container 30 by separating the cover portion 200 from the main body 100 through the operation of the user.

[0213] On the other hand, the container cap 10 having the above-mentioned structure can be formed by injection molding using a synthetic resin material.

[0214] At this time, considering the convenience of manufacturing and reuse after use, the container cap 10 of the present invention is preferably a body portion 100, a cover portion 200 and a separation portion 300 formed in one piece.

[0215] Container structure

[0216] On the other hand, the container cover 10 having the above-mentioned structure can be combined with containers of various structures.

[0217] In particular, the container cover 10 of the present invention is suitable for storing powder, especially a container 30 having contents of a granular structure, and thus the container 30 structure can also be specifically used to discharge the contents of the granular structure.

[0218] Specifically, if Figure 22 to Figure 24 The container 30 of the present invention may be provided with a partitioning member 640 for forming a content discharge passage 33 .

[0219] The partition member 640 is provided inside the container 30 and is configured to form the content discharge passage 33 , and various structures may be employed.

[0220] As an example, the partition member 640 may form a content passage 39 leading from a lower end to the discharge passage 33 .

[0221] On the other hand, two channels are formed at the upper end of the partition member 640, namely, a discharge channel 33 and an entry channel 31 for the contents to enter the interior. Fig.23 As shown, it is necessary to prevent the contents from being discharged through the inlet channel 31 when the inlet channel 31 is more inclined than the horizontal.

[0222] To this end, the container 30 is rotatably provided with a door member 620 , which is provided at an upper end portion of the inlet passage 31 and opens and closes the inlet passage 31 according to an inclination angle of the container 30 .

[0223] The door member 620 is a structure provided at the upper end portion of the inlet passage 31 and opening and closing the inlet passage 31 according to the tilt angle of the container 30, and may adopt various structures.

[0224] At this time, the door component 620 should be supported and set inside the container 30, and can be combined with the inner circumferential surface of the container 30 by setting a combination part 610, and the combination part 610 is combined with a hinge part 630 that can be hingedly combined with the door component 620 and is combined with a supporting combination part 35 formed on the inner circumferential surface of the container 30.

[0225] In addition, in order to prevent the door component 620 from over-rotating during rotation, a clamping portion 641 may be formed at the upper end of the partitioning member 640 , and the clamping portion 641 clamps the door component 620 to prevent the door component 620 from over-rotating.

[0226] On the other hand, the contents of the granular structure should be discharged smoothly toward the discharge channel 33 side, so Figure 22 to Figure 26c As shown, the bottom structure of the container 30 of the present invention can adopt various structures.

[0227] Specifically, the container 30 may protrude from the end to form an apex portion 37 so that the content of the granular structure is discharged toward the discharge channel 33 side.

[0228] The apex portion 37 is a structure that protrudes from the end to discharge the contents of the granular structure to the discharge channel 33 side. In order to improve the formation effect, it is preferably formed to have a height H greater than 1 / 4 of the lower end diameter D of the container 30.

[0229] On the other hand, since the apex portion 37 is formed, an inclined surface 36 is formed which is inclined toward the lower edge of the container 30 , and the content can be guided to the lower edge of the container 30 .

[0230] Then, if Fig.25a and Fig.25b , Fig.26a and Figure 26b As shown, the apex portion 37 may be formed in a symmetrical structure at the center.

[0231] In particular, Fig. 22 and Fig.23 , Fig.25c and Fig.26c As shown, in order to guide the contents to move toward the discharge channel 33 , the apex portion 37 is preferably configured to be asymmetrical and formed on the side away from the discharge channel 33 .

[0232] At this time, in order to guide the movement of the contents, a plurality of ribs 651 protruding upward from the bottom surface may be formed on the inclined surface 36 .

[0233] The plurality of ribs 651 are formed on the inclined surface 36 and protrude upward from the bottom surface in order to guide the movement of the contents. Fig.25b and Fig.25c The shown can be formed into various structures.

[0234] On the other hand, if external air or the like enters the interior of the container 30 , the contents may deteriorate, and therefore the container cover 10 coupled to the container mouth 20 preferably has an insulating structure that can prevent external air from entering the container mouth 20 to the greatest extent.

[0235] Accordingly, the cover 200 and at least one of the container mouth 20 form a plurality of closely contacting parts that are in close contact with each other. To prevent external air from entering the container 30 from the outside, the closely contacting parts may be configured as closed curves surrounding the container mouth 20 .

[0236] In particular, an insulating structure for sealing the interior of the container 30 is preferably provided at the cover portion 200 coupled to the upper end portion of the container mouth 20 .

[0237] That is, on the other hand, in order to improve the sealing force of the container 30 , the cover 200 may include an inner ring 290 , also called a ring gasket, which protrudes from the bottom surface and is inserted into the inner circumference of the container mouth 20 .

[0238] The inner ring 290 is a portion protruding from the bottom surface of the cover 200 and inserted into the inner circumference of the container mouth 20 in order to improve the sealing force of the container 30 , and can adopt various structures according to the contact structure with the container mouth 20 .

[0239] The cover 200 may be combined using a snap-on combination structure (eg, a one-piece and two-piece one-touch cover and an undercut cover structure).

[0240] Here, the snap-on structure refers to a structure in which a circular ring is protruded from the outer circumference of the container mouth 20 and a ring-shaped clamping block is formed on the inner circumference of the container cover 10 to clamp on the circular ring of the container mouth 20 for connection.

[0241] The threaded connection structure refers to a structure in which an external thread is formed on the outer peripheral surface of the container mouth 20 and an internal thread that is threadedly connected to the external thread is formed on a part of the inner peripheral surface of the container cap 10 for connection.

[0242] At this time, the outer circumference of the container mouth 20 is formed with one or more annular coupling protrusions 24 , and the inner circumference of the cover 200 is formed with an annular coupling protrusion 290 to be inserted into the coupling protrusion 24 formed on the container mouth 20 , so that the cover 200 can be coupled to the container mouth 20 .

[0243] Then, the main body 100 combined with the cover 200 can be combined with the container mouth 20 in various ways, such as threaded combination or snap-on combination.

[0244] On the other hand, the cover 200 may be formed with a plurality of close contact portions, and the plurality of close contact portions come into close contact with the container mouth 20 by coming into close contact with the container mouth 20 in a relatively close manner.

[0245] Then, in order to prevent external air from entering the container 30 from the outside, the close contact portion forms a closed curve surrounding the container mouth 20, and various structures can be adopted according to the formation position, formation structure and number of the close contact portion.

[0246] The isolation structure is described in detail below with reference to a more specific embodiment. Then, for the convenience of description, the characteristic part is described in detail.

[0247] Furthermore, the insulating structure is described according to the embodiments, but more than one embodiment may be combined within the scope not conflicting with each other.

[0248] First embodiment

[0249] like Fig.27a As shown, the cover 200 may be formed with one or more inner circumferential protrusions 21 , which protrude toward the inner ring 290 to contact the outer circumferential surface of the inner ring 290 when the cover 200 is coupled to the container mouth 20 .

[0250] The inner circumferential protrusion 21 is a portion that protrudes toward the inner ring 290 to contact the outer circumferential surface of the inner ring 290 , and is formed into a ring shape in the circumferential direction based on the central axis in the longitudinal direction of the cover 200 .

[0251] Then, the inner circumferential protrusion 21 is preferably formed into a gentle curve so that the cross section of the container mouth 20 in the longitudinal direction is in surface contact with the outer circumferential surface of the inner ring 290 rather than in line contact.

[0252] On the other hand, the cover 200 may be formed with one or more inner ring protrusions, which are similar to the above-mentioned inner circumferential side protrusions 21 and protrude toward the inner circumferential surface of the cover 200 so as to contact the inner circumferential surface of the cover 200 when the cover 200 is combined with the container mouth 20.

[0253] The inner ring protrusion protrudes toward the inner circumference of the cover 200 to contact the inner circumference of the cover 200 when the cover 200 is coupled to the container mouth 20 , and can have a ring shape in the circumferential direction based on the central axis in the longitudinal direction of the container mouth 20 .

[0254] Then, the inner ring protrusion is preferably formed into a gentle curve so that the cross section of the container mouth 20 in the length direction is in surface contact with the inner circumference of the container mouth 20 instead of line contact.

[0255] On the other hand, in order to provide sealing force for the container 30, the cover 200 may be formed with an intermediate ring 210, which is inserted into a recessed groove 220 formed integrally along the circumference at the upper end of the container mouth 20 and formed on the bottom surface of the cover 200 when the cover 200 is combined with the container mouth 20.

[0256] The intermediate ring 210 is a ring inserted into a concave groove 220 formed integrally along the circumference at the upper end of the container mouth 20 and formed on the bottom surface of the cover 200 when the cover 200 is combined with the container mouth 20. Various structures can be adopted according to the contact structure with the concave groove 220.

[0257] As an example, the vertical cross section of the intermediate ring 210 may be formed into an inverted triangle or an inverted trapezoid. At this time, the end of the intermediate ring 210 may adopt various shapes, such as a flat surface or a curved surface.

[0258] Then, the recessed groove 220 into which the intermediate ring 210 is inserted may be formed into a shape corresponding to the cross-sectional shape of the intermediate ring 210, and preferably formed into a shape with a width reduced to a greater extent than the cross-sectional width of the intermediate ring 210, so that the intermediate ring 210 can be inserted in close contact.

[0259] On the other hand, of course, more than two recessed grooves 220 and intermediate rings 210 may be formed according to the sealing force.

[0260] On the other hand, in forming the above-mentioned recessed groove 220 , the recessed groove 220 can be formed by two upper end portions 221 and 222 (inner and outer) constituting the upper end portion of the container mouth 20 .

[0261] At this time, the two upper end portions 221 and 222 are preferably formed with an inclined structure having elastic force at the portion constituting the recessed groove 220 .

[0262] Then, the outer peripheral surface of at least one of the two upper end portions 221 and 222 is preferably formed into a curved surface.

[0263] At this time, if Fig.27a As shown, the cover 200 is formed with an inclined surface 215 that contacts the outer peripheral curved surface of the upper end portions 221 and 222, so that when the cover 200 is combined with the container mouth 20, the cover 200 and the container mouth 20 are in close contact, thereby forming more than one close contact portion.

[0264] On the other hand, the upper end of the container mouth 20, that is, the two upper end portions 221 and 222, may be formed such that the inner upper end 221 may be lower than the outer upper end 222 with the concave groove 220 as the center.

[0265] Second embodiment

[0266] like Figure 27b As shown, based on the same or similar structure as the first embodiment, the upper end portion of the container mouth 20 is increased or separately extended to form one or more contact rings 950, 960, and the contact rings 950, 960 extend at the lower end of the cover 200 so as to be in close contact with the upper end portion of the container mouth 20.

[0267] The contact rings 950 and 960 are portions extending from the lower end of the cover 200 to be in close contact with the upper end of the container mouth 20 , and may be configured in a ring shape.

[0268] In particular, the contact rings 950 and 960 may be composed of an inner ring 950 and an outer ring 960 , and may be inserted into the upper end portion of the container mouth 20 .

[0269] Third embodiment

[0270] On the other hand, in terms of sealing the lid 200 and the container mouth 20, when flexibility is imparted to the mutually contacting portions, the sealing force of the container can be greatly improved.

[0271] Accordingly, as stated Figures 28a to 28c As shown, one or more flexibility imparting grooves 231 , 232 , 233 are formed in the container mouth 20 , and pressure contact portions 241 , 242 , 215 for pressure contact may be formed in the cover 200 at positions corresponding to the flexibility imparting grooves 231 , 232 , 233 .

[0272] The flexibility imparting grooves 231 , 232 , 233 are grooves formed to impart flexibility to the contacting portion of the cover 200 and the container mouth 20 to improve the sealing force of the container, and the grooves may be formed in any contacting portion of the cover 200 and the container mouth 20 .

[0273] As an example, Fig.28a and Fig.28c As shown, the flexibility imparting groove may be composed of flexibility imparting grooves 231 , 233 formed at the upper end of the container mouth 20 .

[0274] The flexibility imparting grooves 231 and 233 formed at the upper end of the container mouth 20 may be annular grooves formed at the upper end of the container mouth 20 or the concave grooves 220 proposed in the first embodiment.

[0275] In particular, the flexibility imparting grooves 231, 233 formed at the upper end of the container mouth 20 are preferably formed near the inner peripheral surface ( Fig.28c ) or the outer surface ( Fig.28a ) is formed so as to be deformable when in contact with the cover portion 200.

[0276] On the other hand, as another example, Fig.28b As shown, in a case where the flexibility imparting groove 232 formed at the upper end of the container mouth 20 is formed near the inner circumferential surface in the upper end of the container mouth 20, the cover part 200 forms an inclined surface 215 or the like as a pressurized contact part 215 at a corresponding position so that the part forming the flexibility imparting groove 232 can be pressurized and contacted when the container mouth 20 is combined with the cover part 200.

[0277] like Fig.28a As shown, in a case where the flexibility imparting groove 231 formed at the upper end of the container mouth 20 is formed near the outer peripheral surface in the upper end of the container mouth 20, the cover part 200 forms an inclined surface 241 or the like as a pressurized contact part 241 at a corresponding position so that the part forming the flexibility imparting groove 231 can be pressurized and contacted when the container mouth 20 is combined with the cover part 200.

[0278] On the other hand, Fig.28b As shown, in forming the press contact portion 241 on the cover portion 200, in addition to a simple inclined surface, the press contact portion 241 can also be formed on the outer ring 950 of the second embodiment.

[0279] As another example, Fig.28b As shown, the flexibility imparting groove 232 may be formed on the outer peripheral surface of the container mouth 20 .

[0280] At this time, in order to form the flexibility imparting groove 232 pressurized by the cover 200, a ring-shaped flexibility imparting protrusion 230 is formed on the outer peripheral surface of the container mouth 20, and the flexibility imparting groove 232 is formed by being recessed from the upper side to the lower side of the flexibility imparting protrusion 230, thereby forming the flexibility imparting groove 232.

[0281] Then, the cover portion 200 may form a pressurizing contact portion 242 on the inner circumferential surface of the cover portion 200 corresponding to the flexibility imparting groove 232 .

[0282] The pressurizing contact portion 242 may be formed of an upwardly inclined surface so as to pressurize a portion of the flexibility imparting protrusion 230 where the flexibility imparting groove 232 is formed by descending the cover 200 when the cover 200 is coupled to the container mouth 20 .

[0283] As described above, the pressurized contact portions 241, 242, 215 are portions formed on the cover portion 200 for pressurizing and contacting at positions corresponding to the flexibility imparting grooves 231, 232, 233, and may be any structure as long as the portion having the flexibility imparting grooves 231, 232, 233 can be pressurized.

[0284] Specifically, the pressurized contact portions 241, 242, 215 are lowered by the cover portion 200 rotating and / or lowering relative to the container mouth 20, and the force applied by the lowering pressurizes the portions having the flexibility imparting grooves 231, 232, 233. In view of this, the pressurized contact portions 241, 242, 215 are preferably formed as inclined surfaces.

[0285] However, the press contact portions 241 , 242 , 215 may of course have various structures other than the inclined surface, such as protrusions, etc., as long as the portion formed with the flexibility imparting grooves 231 , 232 , 233 can be pressurized by the force applied by descent.

[0286] Fourth embodiment

[0287] On the other hand, various embodiments can be used to intentionally increase the portion where the cover 200 and the container mouth 20 are in close contact with each other when combined to improve the sealing force of the container.

[0288] Compared to Fig.28a In the structure shown, the cover 200 may further include an auxiliary inner ring 280 between the upper end portion of the container mouth 20 and the inner ring 290 .

[0289] The auxiliary inner ring 280 may be formed to protrude downward from the bottom surface of the cover 200 between the upper end portion of the container mouth 20 and the inner ring 290 .

[0290] At this time, in order to prevent interference with the inner ring 290 , the auxiliary inner ring 280 is preferably shorter than the upper and lower lengths of the inner ring 290 .

[0291] Then, the auxiliary inner ring 280 is preferably inclined toward the upper end of the container mouth 20 , and the upper end of the container mouth 20 is also preferably formed with an inclined surface as a pressurized contact portion 241 at the portion in contact with the auxiliary inner ring 280 .

[0292] On the other hand, as described in the first embodiment, the container mouth 20 may form an inner peripheral side protrusion 21 that contacts the outer peripheral surface of the inner ring 290 .

[0293] The structure described above increases the contact area between the cover 200 and the container mouth 20, thereby improving the sealing force of the container.

[0294] like Fig.29b As shown, the pressurized contact portion 241, which is used to pressurize the portion having the flexibility imparting groove 234, can be formed into an inclined surface by replacing the structure of the auxiliary inner ring 280 with a portion of the inner ring 290 (the inner ring 290 and the auxiliary inner ring 280 can be regarded as being integrated with each other).

[0295] On the other hand, Fig.29a and Fig.29b In the illustrated embodiment, regarding the formation of the flexibility imparting groove 231 or the recessed groove 220, as shown in FIG. Fig.28a As shown, it can be formed by the inner upper end portion 222 and the outer upper end portion 221. The heights of the inner upper end portion 222 and the outer upper end portion 221 can be the same or any one of them can be formed to be higher.

[0296] In particular, Fig.29a and Fig.29b In the embodiment, the height of the inner upper end portion 222 may be smaller than the height of the outer upper end portion 221 .

[0297] On the other hand, Fig.29c As shown, the flexibility imparting groove 234 may be formed at a position close to the outer peripheral surface side in the upper end of the container mouth 20 .

[0298] Here, the cover part 200 may be formed with an inclined surface 215 as the press contact part 215 to press the portion where the flexibility imparting groove 234 is formed.

[0299] exist Fig.29c In the embodiment, the height of the outer upper end portion 221 may be smaller than the height of the inner upper end portion 222 .

[0300] In addition, if Fig.29d As shown, as a press contact portion for pressurizing the portion where the flexibility imparting groove 234 is formed, a projection 244 a may be formed on the cover portion 200 .

[0301] On the other hand, in order to improve the sealing force of the container, it is preferred to relatively increase the contact portion between the upper end portion of the container mouth 20 and the cover 200. In particular, it is preferred that the plurality of contact portions are formed in plurality along the path from the outside of the container to the inside of the container rather than being connected to each other.

[0302] As a first example, Fig.30a As shown, based on the inner ring 290 proposed in the first embodiment and the inner peripheral side protrusion 21 in contact with the outer peripheral surface of the inner ring 290, the cover 200 can also form an auxiliary inner ring 280 in close contact with the upper end portion of the container mouth 20.

[0303] The auxiliary inner ring 280 may be formed to protrude downward from the cover 200 , particularly from the bottom surface of the cover 200 , between the upper end portion of the container mouth 20 and the inner ring 290 .

[0304] At this time, in order to prevent interference with the inner ring 290 , the auxiliary inner ring 280 is preferably formed to be shorter than the upper and lower lengths of the inner ring 290 .

[0305] Then, the auxiliary inner ring 280 is preferably formed to contact the upper end portion of the container mouth 20 when the cap 200 is coupled to the container mouth 20 .

[0306] To this end, the cross section of the upper end portion of the container mouth 20 is preferably formed into a curved surface, and an inner peripheral side auxiliary protrusion 122 may be formed in which the inner peripheral surface of the upper end portion of the container mouth 20 protrudes toward the inner peripheral surface of the auxiliary inner ring 280 .

[0307] As a second example, Fig.30b As shown, in Fig.30b In the illustrated structure, at least one of the surfaces where the auxiliary inner ring 280 and the upper end portion of the container mouth 20 contact each other may be formed as an inclined surface 180, 241a.

[0308] On the other hand, in the first and second examples, the auxiliary inner ring 280 can of course be located between the upper end of the container mouth 20 and the wall portion instead of between the upper end of the container mouth 20 and the inner ring 290 and can symmetrically form a corresponding structure.

[0309] As a third example, Fig.30c As shown, in Fig.30b The flexibility imparting groove 231 may also be formed on the structure.

[0310] Here, the inner peripheral surface of the container mouth 20 may be formed as follows Fig.30a The auxiliary protrusion 122 is shown.

[0311] As a fourth example, Fig.30d As shown, in Fig.30aThe flexibility imparting groove 231 may also be formed on the structure.

[0312] As a fifth example, Fig.30e As shown, in Fig.30d In terms of structure, the protruding portion 21 may be formed to be inclined from the upper end of the container mouth 20 to the inner peripheral side.

[0313] Specifically, the inner peripheral surface of the container mouth 20 is inclined in a direction in which the inner diameter decreases from the upper end to the inner peripheral side protrusion 21 .

[0314] With the above structure, when the cover 200 is combined with the container mouth 20, if the cover 200 is lowered relative to the container mouth 20, the outer peripheral surface of the auxiliary ring 280 is in close contact between the upper end of the container mouth 20 and the inner peripheral side protrusion 21.

[0315] Fifth embodiment

[0316] On the other hand, the portion where the cover 200 and the container mouth 20 are closely contacted with each other when combined is intentionally increased to improve the sealing force of the container, and various embodiments can be adopted.

[0317] In particular, if the upper end portion contacting the container mouth 20 and the contact portion of the cover 200 are improved, the sealing force of the container can be improved.

[0318] like Fig.31a and Fig.31b As shown, the container according to the fifth embodiment of the present invention is a container mouth 20 having a recessed groove 22 formed in the center through an inner upper end portion 222 and an outer upper end portion 221, and the cover portion 200 can form an inner inclined surface 241 and an outer inclined surface 242 that contact the inner portion of the inner upper end portion 222 and the outer portion of the outer upper end portion 221.

[0319] Specifically, the upper end portion of the container mouth 20 may form a groove 220 at the center through the inner upper end portion 222 and the outer upper end portion 221 .

[0320] 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 .

[0321] Then, in order to make the upper ends of the inner upper part 222 and the outer upper part 221 easily deform toward the side where the width of the groove 220 is narrowed, that is, to make the inner upper part 222 and the outer upper part 221 easily tighten and deform with each other, the side wall part of the groove 220 is preferably formed to be inclined upward.

[0322] That is, the inner upper end portion 222 and the outer upper end portion 221 preferably have a “V” shape.

[0323] On the other hand, the cover 200 is formed with an inner inclined surface 241 and an outer inclined surface 242 which are in contact with the inner portion of the inner upper end portion 222 and the outer portion of the outer upper end portion 221 .

[0324] The inner inclined surface 241 and the outer inclined surface 242 are formed on the cover 200 to contact the inner portion of the inner upper end portion 222 and the outer portion of the outer upper end portion 221 , and various structures may be adopted.

[0325] As an example, Fig.31a and Fig.31b As shown, the inner inclined surface 241 can be formed as a part of the inner ring 290.

[0326] In addition, when the auxiliary inner ring 280 is present, the inner inclined surface 241 may be formed as a part of the auxiliary inner ring 280 .

[0327] On the other hand, Fig.31b As shown, the cover 200 may be formed with an inner contact ring 960 and an outer contact ring 950 , and may be formed with facing recessed grooves 292 to be inserted into at least a portion of the end portion of the container mouth 20 .

[0328] The inner contact ring 960 and the outer contact ring 950 are formed on the cover 200 to form the facing recessed grooves 292 for inserting at least a part of the end portion of the container mouth 20, and various structures may be adopted.

[0329] As an 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 200 .

[0330] At this time, it is preferable that the inner contact ring 960 and the outer contact ring 950 have portions that are in contact with the upper end portion of the container mouth 20 formed into curved surfaces.

[0331] Then, in order to make the lower ends of the inner contact ring 960 and the outer contact ring 950 easily deform to expand the width of the opposing recessed groove 292, that is, to make the inner contact ring 960 and the outer contact ring 950 easily expand and deform with each other, the side wall portions of the opposing recessed grooves 292 are preferably formed to be inclined upward.

[0332] In other words, the inner contact ring 960 and the outer contact ring 950 preferably have an inverted “V” shape facing downward.

[0333] On the other hand, the upper end portion of the container mouth 20 is formed into a tapered shape so as to be easily inserted into the opposing recessed groove 292 formed by the inner contact ring 960 and the outer contact ring 950 .

[0334] Then, if Fig.31b As shown, the upper end portion of the container mouth 20 is preferably formed with inclined surfaces 961 and 951 expanding inwardly and outwardly with the uppermost end as the reference so as to be easily inserted into the opposing recessed grooves 292 .

[0336] On the other hand, referring to the above-mentioned embodiment, as a tool for improving the sealing force of the container, it is preferred to increase the contact portion between the cover 200 and the container mouth 20, especially relatively increase the contact portion between the upper end portion of the container mouth 20 and the cover 200.

[0337] Here, it is preferable that the plurality of contact portions are formed along a path from the outside of the container to the inside of the container rather than being connected to each other.

[0338] In particular, the formation of the plurality of contact portions is achieved through structural deformation of the cover 200 and the container mouth 20, and can be realized by forming various angles, inclined surfaces of the structure, and flexibility imparting grooves.

[0339] In addition, the structures of the plurality of contact portions may be changed by interchanging the structures of the cover 200 and the container mouth 20 .

[0340] Various modifications of the container mouth 20 for forming a plurality of the contact portions along a path from the outside of the container to the inside of the container will be described below.

[0341] like Fig.32a As shown, the container mouth 20 may form an inner upper end portion 222 and an outer upper end portion 221 at the upper end portion with the concave groove 220 as the center.

[0342] Here, the concave groove 220 is formed close to the inner side or the outer side, so that the width of any one of the inner upper end portion 222 and the outer upper end portion 221 can be smaller than the width of the remaining one, so as to be easily deformed by contacting the cover 200.

[0343] In addition, the heights of the inner upper end portion 222 and the outer upper end portion 221 may be the same or different.

[0344] Fig.32a The case shown is a case where the width of the inner upper end portion 222 is smaller than the width of the outer upper end portion 221.

[0345] Then, the recessed groove 220 may be formed to gradually expand in width toward the upper side.

[0350] exist Fig.32c The container mouth 20 shown can also be formed from Fig.32a The recessed groove 220 has a central protruding upper end portion 225 that protrudes toward the upper side.

[0351] In particular, the central protruding upper end portion 225 may be formed to be higher than the inner upper end portion 222 and the outer upper end portion 221 , and the concave groove 220 may be formed into two divided concave grooves 220 a and 220 b .

[0352] At this time, the cover 200 coupled to the container mouth 20 is preferably formed into a ring-shaped groove into which the central protruding upper end portion 225 is inserted.

[0355] Fig.32e is Fig.32a A variation of the container mouth 20 is shown.

[0356] exist Fig.32e The container mouth 20 shown is as Fig.32a In a converse case, the width of the outer upper end portion 221 may be smaller than that of the inner upper end portion 222 .

[0359] That is, Figure 32f As shown, the flexibility imparting groove 232 may be constituted by a flexibility imparting groove 232 formed on the outer peripheral surface of the container mouth 20 .

[0360] At this time, in order to form a flexibility imparting groove 232 pressurized on the cover 200, a ring-shaped flexibility imparting protrusion 230 is formed on the outer peripheral surface of the container mouth 20, and the flexibility imparting groove 232 is formed by being recessed from the upper side to the lower side of the flexibility imparting protrusion 230, thereby forming the flexibility imparting groove 232.

[0361] Here, the flexibility imparting groove 232 may be formed oppositely by a groove forming protrusion ring 238 extending toward the upper side.

[0362] As another example, Figure 32g As shown, the flexibility imparting groove 235 may be constituted by a flexibility imparting groove 235 formed on the inner peripheral surface of the container mouth 20 .

[0363] At this time, in order to form a flexibility imparting groove 235 that is pressurized on the cover portion 200, a ring-shaped inner flexibility imparting portion 250 is formed on the inner circumferential surface of the container mouth 20, and the flexibility imparting groove 232 is formed by being recessed from the upper side to the lower side of the inner flexibility imparting portion 250, thereby forming the flexibility imparting groove 235.

[0364] Here, the flexibility imparting groove 235 may be formed oppositely by a groove forming protrusion ring 239 extending toward the upper side.

[0365] On the other hand, the cover portion 200 has a structure for press-forming the groove protrusion ring 239, such as an inclined surface or an inner ring.

[0366] On the other hand, in order to form the plurality of contact portions based on the path from the outside of the container 30 to the inside of the container 30 , various modifications of the cover 200 will be described below in addition to or separately from the container mouth 20 .
