TECHNICAL FIELD

The present invention relates to a bottle cap, and more particularly, to a bottle cap for effectively mixing concentrate with water, concentrate with general beverage, granulation with water, or powder with water, and so on.

Also, the bottle cap may be used in industrial fields such as medicine, pharmacy, cosmetics, and the like and alcoholic beverage fields so as to improve mixture of heterogeneous materials.

BACKGROUND ART

In general, a separate space has to be provided in a container to mix powder or concentrate with liquid beverage stored in the beverage container.

A conventional structure for mixing heterogeneous materials with each other as described above is disclosed in U.S. Pat. Nos. 6,962,254, 6,230,884, and 6,854,595.

However, it is difficult to effectively overcome limitations in functional structure, mixing efficiency, barrier, responsiveness of a product line, use convenience, and the like. Thus, the conventional structure is not popularized until now.

Also, although a joint venture technology of US, Germany, and Austria and a Japanese technology are coming into the spotlight in the international society, the Japanese technology has been popularly commercialized first.

However, the Japanese technology (JP-P-2001-0018542, Jun. 19, 2001) may have a problem in which a portion for forming an opening drops into a container. As a result, it is apprehended that child swallow the dropping portion. Recently, although a container neck having a new structure for preventing a discharge device from being separated has been developed, there is a problem in which it is impossible to apply this structure to the existing container neck.

Also, although US Patent Publication No. 2003-72850 is disclosed, this invention has a limitation in which it is difficult to technically secure airtightness, workability, mold manufacture, and insertion of a content into a receiving part.

MODE FOR CARRYING OUT THE INVENTION

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

A bottle cap 1 for receiving a different kind of material includes a min body 10 having a structure that is capable of being coupled in one touch manner, rotation manner, or adhesion manner, and the like in a discharge direction of a content of a container. A receiving part 200 is assembled into the main body 100 in an adhesion or fitting manner.

Also, a storage space 210 for containing the different kind of material is defined in the receiving part 200, and an opening/closing hole 202 through which the content of the storage space 201 drops down and is mixed is defined in a lower portion of the receiving part 200.

Also, an auxiliary assembly part 300 is assembled around an upper main body mouth 101 of the main body 100 having the receiving part 200 therein. Also, an operation mouth 301 is disposed outside the auxiliary assembly part 300 having the above-described configuration between the operation mouth 301 and the sealing space 302, and an opening part screw thread 303 is disposed on an outer surface of the operation mouth 301.

Also, an operation sealing part assembly part 304 is disposed inside the auxiliary assembly part 300, and a coupling part 401 of the operation sealing part 400 is coupled around the operation sealing part assembly part 304. A reinforcement piece 402 that extends by a predetermined length is disposed on a lower portion of the coupling part 401 of the operation sealing part 400, and an opening/closing hole sealing part 403 that extends from the reinforcement piece 402 is disposed on an upper portion of the coupling part 401 of the operation sealing part 400. A discharge hole 404 is defined in one side of the opening/closing hole sealing part 403.

Also, when an opening/closing operation part 500 is assembled around the auxiliary assembly part 300, a discharge hole 501 is defined inside the operation part 500. A space part 503 having both opened sides is disposed under an inner sealing surface 502 of the discharge hole 501, and a discharge member opening part 504 for pulling a discharge member 600 that is separately assembled is disposed on a lower end of a portion except for the space.

Also, an auxiliary sealing part 505 disposed in the sealing part space 302 is disposed on a portion of the operation part 500 corresponding thereto. An opening/closing part-side corresponding part 506 having a screw thread so that the operation part 500 vertically moves to correspond to the opening/closing part screw thread 303 is disposed on the operation part 500 that corresponds thereto.

Also, an air compression prevention groove 305 having a long groove or long protrusion shape is defined in the auxiliary assembly part 300 corresponding to the main body mouth 101 to prevent air compression from occurring while the auxiliary assembly part 300 is assembled around the main body mouth 101. A stopper 507 is disposed on an inner wall of a lower end of the opening/closing part-side corresponding part 506 to prevent the operation part 500 from being separated by being caught on a lower end of the opening/closing part screw thread 303 disposed on the outer surface of the operation mouth 301.

Also, an air discharge part 306 is disposed on a lower end of the sealing part space 302 to prevent the air compression from occurring while the auxiliary sealing part 505 is inserted into the sealing part space 302.

Also, the discharge member 600 is assembled around the inner wall of the main body mouth 101 of the main body 100, and a discharge stopper 601 is disposed on an inner wall of an upper end of the discharge member 600 so that the discharge member stopper 601 is caught by the discharge member opening part 504 of the operation sealing part 400 corresponding thereto.

Also, a sealing part 602 formed of a soft material such as a silicon resin is disposed on a lower end of the discharge member 600, and the sealing part 602 covers the opening/closing hole 202 of the receiving part 200.

In the bottle cap 1 having the above-described components, the receiving part 200 is assembled inside the main body 100, and the opening hole 202 of the receiving part 200 is blocked by the sealing part 602 of the discharge member 600. A liquid or powder is injected into the storage space 201 of the receiving part 200 having the above-described configuration through the main body mouth 101. In a method for sealing the main body mouth 101 having the above-described configuration, the operation sealing part 400 is assembled with the auxiliary assembly part 300, and the operation part 500 is coupled around the auxiliary assembly 300 and the operation sealing part 400.

Also, when the operation part 500 including the auxiliary assembly part 300 and the operation sealing part 400 presses the main body mouth 101 of the main body 100, the operation part 500 is coupled to a mouth fixing stopper 307 of the auxiliary assembly part 300 over a stopper 102 disposed outside the main body mouth 101.

For reference, FIG. 2 is a view for explaining a principle in which the discharge member opening part 504 of the operation part 500 is coupled around the reinforcement piece 402 of the operation sealing part 400. That is, FIG. 2 is a cutaway perspective or exploded view of a main part for easily explaining the process in which the coupling part 401 of the operation sealing part 400 is assembled with the operation sealing part assembly part 304 of the auxiliary assembly part 300 corresponding thereto.

The operation effects of the present invention will be described below.

The bottle cap 1 as illustrated in FIG. 1 is coupled or assembled in the discharge direction of the content of the container. In this state, when the operation part 500 rotates (is opened), the opening/closing part-side corresponding part 506 of the operation part 500 moves upward along the opening/closing part screw thread 303. In this process, the discharge member opening part 504 moves upward by being caught by the discharge member stopper 501 of the discharge member 600.

Also, in this process, the operation part 500 moves upward while rotating together with the operation sealing part 400. As illustrated in FIG. 4, when the operation part 500 is continuously opened, the stopper 507 is hung on the opening/closing part-side corresponding part 506 that corresponds to a lower end of the screw thread structure and thus does not move upward any more. In this state, the discharge member 600 may also be closely attached to the inner wall of the main body mouth 101.

Also, while the operation part 500 moves upward, the sealing part 602 gets out of the opening/closing hole 202. In this process, the different kind of material stored in the storage space 201 drops into the container through the opening/closing hole 202 and then is mixed.

Also, while the sealing part 602 of the discharge member 600 gets out of the opening hole 202, a discharge hole inner wall 508 of the operation part 500 may also get out of the opening/closing hole sealing part 403 to form the discharge hole 501. The contents maxed within the container may be finally discharged through the discharge hole 501 via the opening hole 202. Here, when the container is inclined in one direction, the contents within the container may be more easily discharged.

Also, as illustrated in FIG. 4, a groove 509 may be defined in an outer wall that is opposite to the discharge hole inner wall 508 so that a remaining liquid easily drops while the operation part 500 is sealed again.

For reference, FIG. 5 is a cross-sectional view of the discharge member opening part 504, and FIG. 3 is a view illustrating a state, in which the operation part 500 and the discharge member 600 operate, by using dotted lines.

In addition, in the state of FIG. 4, the discharge of the content through the discharge hole 501 may be performed through the discharge hole 501 of the final operation part 500 by the discharge hole 404 of the operation sealing part 400.

According to another embodiment (see FIG. 6), an opening/closing part-side corresponding part 103 is disposed to be slightly spaced in a direction of an outer annular part of the main body mouth 101. A sealing part space 104 in which the auxiliary sealing part 505 is assembled is defined between the main body mouth 101 and the opening/closing part-side corresponding part 103. The operation sealing part 400 is configured so that the coupling part 401 of the operation sealing part 400 is coupled to the operation sealing part assembly part 105 disposed on the inner wall of the main body mouth 101.

In the use of the present invention as described above, when the operation part 500 is opened, the discharge member opening part 504 ascends by catching the discharge member stopper 601 of the discharge member 600. In this process, the operation sealing part 400 rotates together with the operation part 500. Also, the operation part moves upward from the operation sealing part 400 to form the discharge hole.

According to further another embodiment (see FIG. 7), the current embodiment fundamentally includes the same ideas of the present invention described with reference to FIG. 6. However, a screw groove 1006 having a screw shape is defined in an outer annular portion of the main body mouth 101, and a screw 510 is formed on a portion of the operation part 500 that corresponds thereto.

In the use of the present invention as described above, an operation part 500 is opened, a screw thread 510 moves upward along the screw grove 106 of the main body mouth 101 and thus, the operation part 500 moves upward with respect to the operation sealing part 400.

According to further another embodiment (see FIG. 8), the current embodiment describes an example in which the discharge member 600 assembled inside the bottle cap 1 is lifted by using a different method. Explaining in addition to the description of FIG. 1, while the operation part 500 together with the operation sealing part 400 moves upward, the discharge member opening part 504 moves along a screw groove 603 corresponding thereto. While the operation part 500 is opened, the discharge member opening part 504 moves along the screw groove 603 on an inner wall of the discharge member 600. In this process, a fixing groove may be defined in an outer direction of the discharge member 600 so that the discharge member 600 does not rotate, but is lifted upward. A fixing part 107 is disposed on the inner wall of the main body mouth 101 that is a corresponding surface thereof.

More particularly explaining the embodiment of the present invention as described above, as illustrated in FIG. 9, while the discharge member opening part 504 rotates along the screw groove 603, the discharge member 600 moves upward by the induction of the fixing part 107.

According to further another embodiment, FIG. 11 illustrates a process in which, when the operation part 500 is opened, the discharge member 600 descends downward by the induction of the screw groove 603. In this process, the sealing part 602 that blocks the opening/closing hole 202 descends downward, and thus, the opening/closing hole 202 is opened. FIG. 10 illustrates an example in which the discharge member 600 is opened downward.

According to further another embodiment, FIG. 12 illustrates a process in which, when the operation part 500 is opened, a screw thread 605 is disposed on an outer surface of the discharge member 600 so that the discharge member 600 descends downward in a screw manner. Also, a screw thread 109 is formed on an inner wall of the main body mouth 101 corresponding thereto. In use, the discharge member 600 descends downward while the discharge member opening part 504 rotates along the long groove 606.

According to further another embodiment (see FIG. 13), the current embodiment may be a concept that is opposite to that of FIG. 12. That is, when the operation part 500 is opened, the discharge member 600 moves upward. Thus, the operation part 500 rotates to move upward, and a gap between the operation part 500 and the operation sealing part 400 is generated to form a discharge hole. Then, the discharge member 600 rotates by the discharge member opening part 504 in a state where the discharge member 600 is fitted into the long groove 606. In this process, the screw thread 605 formed on an outer annular portion of the discharge member 600 moves upward along the screw thread 109 formed on the inner wall of the main body mouth 101 corresponding thereto. In this process, the sealing part 602 moves upward to open the opening/closing hole 202 that is defined thereunder.

According to further another embodiment (see FIG. 14), when the operation part 500 is opened, the operation sealing part 400 coupled around the operation sealing part assembly part 304 of the auxiliary assembly part 300 seals the discharge hole 501 of the operation part 500. When the operation part 500 is opened, the screw thread 510 ascends along the screw groove defined in the corresponding portion thereof. In this process, the auxiliary sealing part may also move upward.

Also, while the operation part 500 is opened, although the operation sealing part 400 rotates together, a gap between the operation part 500 and the operation sealing part 400 is generated to form a discharge hole 501. Also, while the operation part 500 operates, the discharge opening part 504 of the operation part 500 moves upward, and also, the discharge member 600 may also move upward. In this process, the sealing part 602 ascends to open the opening/closing hole 202.

According to further another embodiment (see FIG. 15), although the current embodiment corresponds to a modified example of FIG. 14, the fundamental component is the same. However, the screw thread 510 of the operation part 500 is directly disposed on the outer annular portion of the auxiliary assembly part 300. Also, in use, the discharge member opening part 504 ascends by a predetermined height by catching the discharge stopper 601 of the discharge member 600, and thus, the opening/closing hole 202 that is defined thereunder is opened. The ascending of the discharge member 600 may occur because the screw thread 510 of the operation part 500 operates so that the operation part 500 moves along the screw groove formed on the outer wall of the auxiliary assembly part 300.

According to further another embodiment (see FIG. 16), in the present invention, while the operation part 500 is lifted upward without rotating, the discharge member 600 on which the discharge stopper 601 is hung on the discharge opening part 504 of the operation part 500 is lifted. In this process, the sealing part 602 that blocks the opening/closing hole 202 is opened.

This is done for a reason in which the content within the storage space 201 of the receiving part 200 is injected through the inner discharge hole of the main body mouth 101 before the operation is coupled to the main body mouth 101. In this state, the groove 405 of the operation sealing part 400 is fitted into and assembled with a protrusion 108 of the main body mouth 101. Simultaneously, the operation part 500 assembles the main body mouth 101. This series of processes may be illustrated in processes that are performed and completed from the state of FIG. 17 to the state of FIG. 16.

According to further another embodiment (see FIG. 18), a discharge member withdrawal stopper 607 is disposed on an upper end of the discharge member 600 so that the discharge member 600 ascends while the operation part 500 moves upward. Also, a stopper 511 may be disposed on a surface of the operation part 500 that corresponds thereto. Also, a screw thread 109 is formed on an outer annular portion of the main body mouth 101, and a screw thread 512 is formed on the operation part 500 that corresponds thereto.

Also, when the operation part 500 is opened, a lower end stopper 513 is disposed on a lower end inner wall of the outer annular portion of the operation part 500 to prevent the operation part 500 from further ascending by being caught by the lower end of the screw thread 109.

In use as described above, in addition that the lower end stopper 513 is caught by and fixed to the lower end of the screw thread 109, an outer annular stopper 608 of the discharge member 600 may be caught by the lower end of the inner wall of the main body mouth 101 and thus may not further move upward.

Also, while the operation part 500 ascends, the operation part 500 is spaced apart from the operation sealing part 400 to form a discharge hole in an upper portion thereof. Simultaneously, the sealing part 602 ascends to open the opening/closing hole 202, and also, the content within the storage space 201 is discharged through the opening/closing hole 202 (see FIGS. 19 and 20).

Also, the operation sealing part 400 is coupled in a manner in which a protrusion 406 is fitted into a groove 609 defined in an upper end of the inner wall of the mouth of the discharge member 600 that corresponds thereto.

According to further another embodiment (see FIG. 21), the present invention relates to a structure in which the discharge member 600 lifts the operation part 500. When the operation part 500 is opened, the operation part 500 together with the discharge member 600 moves upward while a screw thread 514 of the operation part 500 moves along a screw thread 111 formed on the outer annular portion of the opening/closing side part 110. In this process, when a stopper 515 is caught by a mouth stopper 112 of the main body mouth 101, the operation part 500 and the discharge member 600 may not further operate.

Also, in this process, the sealing part 602 gets out of the opening/closing hole 202 to allow the content of the storage space 201 to drop downward. The mixed contents may be discharged through the discharge hole formed when the operation part 500 is spaced apart from the operation sealing part 400.

According to further another embodiment (see FIG. 22), the current embodiment is an application example of FIG. 21. A corresponding stopper 114 fixed to the stopper 515 is disposed on an upper end annular portion of the main body mouth 101, and a groove that is recessed in an annular shape so that the stopper 515 is inserted at a predetermined depth is defined in a lower end of the outer annular portion of the stopper 114.

In the use of the present invention as described above, while the operation part 500 is opened, a discharge member withdrawal stopper 607 ascends by the stopper 511, and then an outer annular stopper 608 of the discharge member 600 is caught by a lower end stopper 113 that corresponds thereto, or the stopper 515 of the operation part 500 is caught by the stopper 114 that corresponds thereto to prevent the discharge member from more ascending upward. In this process, the lower opening/closing hole of the receiving part 200 is opened.

Also, while the operation part 500 is spaced apart from the operation sealing part 400, the discharge hole is defined in the operation part 500 and the operation sealing part 400. Since this has been described in detail with reference to the first embodiment, their detailed description will be omitted.

According to further another embodiment (see FIG. 23), the operation sealing part 400 is assembled with the operation part 500, and the discharge member withdrawal stopper 407 of the operation sealing part 400 is caught by the stopper 511 of the operation part 500.

In this state, when the operation part 500 is coupled around the main body mouth 101, the assembly part 408 is coupled to a discharge member upper end 610. In this state, when the operation part 500 is opened, the discharge member 600 together with the operation part 500 moves upward. In this process, when an outer annular stopper 608 is caught by a lower end stopper 113 of the main body mouth 101, the discharge member 600 may not further move upward, but be stopped.

Also, the contents mixed through a discharge hole formed when the operation part 500 is spaced apart from the operation sealing part 400 are discharged. Here, the contents may be discharged via the discharge hole 404. While the discharge member 600 ascends, the content contained in the storage space 201 of the receiving part 200 may drop down through the operating/closing hole formed when the discharge member 600 ascends.

According to further another embodiment (see FIG. 24), the receiving part 115 having an integrated storage space 116 is disposed in an inner lower portion of the main body 100, and an opening/closing hole 117 is defined in a lower portion of the receiving part 115.

Also, the opening/closing hole 117 is sealed by the sealing part 602, and the sealing part 602 is fitted into the lower end of the discharge member 600. The discharge member 600 is assembled with the main body mouth 101 having an expanded upper portion.

Also, an outer annular stopper 611 is disposed on an outer annular part corresponding part of the discharge member 600 so that a stopper 118 disposed on an upper end of the inner wall of the main body mouth 101 is caught to prevent the discharge member 600 from being separated from the main body mouth 101 above a predetermined degree.

Also, a mouth upper end stopper 612 is disposed on an upper end of the operation part 500, and a stopper 516 caught by the mouth upper end stopper 612 is disposed on a corresponding portion thereof.

In use as described above, when the operation part 500 ascends while an opening stopper 516 catches the mouth upper end stopper 612, and then is caught by the stopper 118 of the main body mouth 101, the discharge member 600 does not ascends and then is stopped.

Also, the opening/closing hole 117 is opened while the sealing part 602 ascends, and thus, the content of the storage space 116 drops down through the opening/closing hole 117. The content dropping and mixed is discharged via the discharge hole 404.

Also, while the operation part 500 is opened, the outer annular stopper 611 is caught by the stopper 118. Then, while the stopper 516 of the operation part 500 gets out of the mouth upper end stopper 612, the upper end of the discharge hole 404 is opened. Thus, the content is discharged through the opened discharge hole 501.

For reference, the operation sealing part 400 is assembled in a manner in which a fixing stopper 409 is fitted into a fixing part 613 of the discharge member 600. While the discharge member 600 moves upward, the sealing part ascends, and when the discharge member descends, the sealing part 602 is caught by a sealing part removing protrusion 119 disposed in a direction of an upper end of the opening/closing hole 117, and thus, the opening/closing hole 117 is not blocked.

Also, in the description of FIGS. 1 to 24, a part that is exposed as a reference numeral (symbol), but is not described in reference numeral (symbol) may be understood as the same reference numeral (symbol) if the same reference numeral (symbol) is used, and the reference numeral (symbol) is previously described. For example, if reference numeral (symbol) “100” in FIG. 22 is not described, and the reference numeral (symbol) “100” is defined as the main body in FIG. 1, reference numeral (symbol) “100” in FIG. 22 may be defined as the main body.
