Capsule cap for beverage container

Abstract

A capsule cap for a beverage container of the present invention includes: a cylindrical lower coupling unit (10) keeping an additive (A) therein; a cutting unit (20) having a cylindrical cutting body (21) inserted in a lower body (11) and vertically moving down to cut a seal (12) so that the additive (A) drops; and an upper coupling unit (30) disposed over the lower coupling unit (30) to be turned and vertically move the cutting unit (20), in which drinking water contained in the beverage container an additive are separately kept, so the drinking water and the additive are prevented from spoiling. Further, spiral guides are formed, so torque is easily changed into straight force, thereby achieving easy cutting and opening.

MODE FOR INVENTION

(6) Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

(7) A capsule cap for a beverage container of the present invention that seals a beverage container B and allows a user to add an additive A kept inside the cap, such as powder or an undiluted solution according to his/her preference, when the user desired to drink drinking water W contained in the beverage container B, as shown in FIG. 2, includes: a lower coupling unit 10 composed of a cylindrical lower body 11 having a seal 12 for sealing the bottom of the lower body 11 to keep an additive therein and a cup-shaped container coupling portion 13 formed on the outer side of the lower body 11 and having a thread around the inner side to be coupled to the entrance of the beverage container B; a cutting unit 20 composed of a cylindrical cutting body 21 inserted in the lower body 11, a cutter 22 formed at a predetermined angle at the lower portion of the cutting body 21 to press and cut a side of the seal 12, and a cutting guide 23 spirally formed around the outer side of the cutting body 21; and an upper coupling unit 30 disposed over the lower coupling unit 10 and composed of an upper pressing guide 31 formed in the same shape as the spiral shape of the cutting guide 23 and a cup-shaped upper body 32 having a thread around the inner side to be coupled to the upper portion of the lower body 11.

(8) The container coupling portion 13 extends downward from the middle portion of the outer side of the lower body 11 and a thread (not shown) to be fitted to the thread on the inner side of the container coupling portion 13 may be formed at the entrance of the beverage container B.

(9) A cutting unit guide groove 11a is vertically formed on the inner side of the lower body 11 and a cutting unit guide projection 20a for vertically moving the cutting unit 20 inserted in the cutting unit guide groove 11a is formed on the outer side of the cutting body 21.

(10) Further, as shown in FIG. 3, an upper body-pressing projection 21a that protrudes outward is formed around the outer side of the upper portion of the cutting body 21 so that the cutting unit 20 is fitted inside the upper body 32.

(11) The upper body-pressing projection 21a may be formed larger than the inner diameter of the upper body 32.

(12) The seal 12 is integrally formed on the inner side of the lower body 11 and a cutting portion 12a that is relatively thin to be easily cut by the cutter 22 is formed around the edge of the seal 12.

(13) A crease 12b is formed at a portion of the edge of the seal 12 so that the seal 12 folds down after being cut along a predetermined portion.

(14) An inserting portion 11b is formed at the lower portion of the lower body 11 to be smaller than the diameter of the lower body 11 so that the lower coupling unit 10 can be easily inserted into the entrance of the beverage container B.

(15) A cutting unit-pressing projection 14 that protrudes inward is formed on the inner side of the lower body 11 to prevent the cutting unit 20 from separating outside by pressing it.

(16) The inner diameter of the cutting unit-pressing projection 14 may be larger than the outer diameter of the cutting unit 20.

(17) An anti-contact groove 22a is formed upward at the cutter 22 to prevent contact with a side of the seal 12, as shown in FIG. 2.

(18) Operation of the capsule cap for a beverage container that has the configuration described above is described hereafter.

(19) According to the capsule cap for a beverage container of the present invention, the lower coupling unit 10 coupling to the beverage container B and keeping an additive A therein, the cutting unit 20 inserted in the lower coupling unit 10 to cut the seal 12 holding the additive A, and the upper coupling unit 30 closing the top of the lower coupling unit 10 and pressing down the cutting unit 20 are combined, so that interaction of these three units allows a user to add the additive A to drinking water W in the beverage container B and drink the mixture according to his/her preference.

(20) That is, as shown in FIGS. 3 to 5, the beverage container B is first filled with drinking water W, the drinking water W is completely isolated from the outside by coupling the lower coupling unit 10 to the upper portion of the beverage container B, and then one of various additives A such as powder or an undiluted solution to be mixed and drunk with the drinking water W is put into the lower coupling unit 10 separately from the drinking water W. Accordingly, it is possible to prevent the drinking water W and the additive A from spoiling by coming in contact with the external air, so a keeping ability can be greatly improved.

(21) Further, it is possible to simply enjoy various beverages without changing the drinking water W itself in the beverage container B by changing the lower coupling unit 10 sealing the upper portion of the beverage container B and filled with the additive A.

(22) When the cutting unit 20 inserted in the lower coupling unit 10 is vertically moved down and cuts the edge of the seal 12 inside the lower coupling unit 10 to drop the additive in the lower coupling unit 10 into the drinking water W, the additive A in the lower coupling unit 10 can be dropped into and mixed with the drinking water W in the beverage container B.

(23) When the upper coupling unit 30 is turned opposite to the coupling direction, as shown in FIG. 5, the bottom end P1 of the spiral upper pressing guide 31 slides to the top end P2 of the spiral cutting guide 23 and the cutting unit 20 is vertically moved down, so the additive A can be dropped with opening of the upper coupling unit 30.

(24) Further, since the cutting unit guide groove 11a is vertically formed on the inner side of the lower body 11 and the cutting unit guide projection 20a is formed on the outer side of the cutting body 21 to be inserted in the cutting unit guide groove 11a, as shown in FIG. 3, even though the upper coupling unit 30 is turned, the cutting unit 20 being in contact with the upper coupling unit 30 can vertically move without turning.

(25) Further, since the upper body-pressing projection 21a protruding outward is formed around the outer side of the upper portion of the cutting body 21 so that the cutting unit 20 is fitted inside the upper body 32, as shown in FIGS. 3 to 5, it is possible to completely seal the additive A in the cutting unit 20 from the external air.

(26) Further, since the cutting unit-pressing projection 14 protruding inward is formed on the inner side of the lower body 11 to prevent the cutting unit 20 from separating outside by pressing it, it is possible to prevent the cutting unit 20 from separating from the lower coupling unit 10 when a user drinks the drinking water after opening the upper coupling unit 30.

(27) Further, since the seal 12 is integrally formed on the inner side of the lower body 11 and a cutting portion 12a that is relatively thin to be easily cut by the cutter 22 is formed around the edge of the seal 12, the seal 12 can be easily cut when the cutter 22 is pressed down.

(28) Further, since the crease 12b is formed at a portion of the edge of the seal 12 so that the seal 12 folds down after being cut along a predetermined portion, the seal 12 folds after being cut, so the additive A can be easily dropped.

(29) Further, since the anti-contact groove 22a is formed upward at the cutter 22 to prevent contact with a side of the seal 12, as shown in FIG. 2, it is possible to prevent the entire edge of the seal 12 from being cut.

(30) The present invention is not limited to the embodiments described above and may be changed and modified in various way by those skilled in the art without departing from the scope of the present invention, and the modifications are included in claims.
