MODE FOR CARRYING OUT THE PREFERRED EMBODIMENTS

[0030] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

[0031] The structure of a closure in accordance with the present invention will be described as follows.

[0032] The closure is divided into an outer wall region 10, a hemispherical (dome) region 30 and a cutting region 40.

[0033] The outer wall region 10 is coupled at its lower portion to an inlet of a container 1, and its upper portion is more protruded than the inlet of the container. A spoon mounting jaw 14 and a wrapper installation jaw 16 are installed at an outer wall 11 of the outer wall region 10. A knurl 12 is installed at an outer surface of the outer wall region. At a lower side of the outer wall region 10 coupled to the inlet of the container 1, there are formed a sealing portion 17, a connected potion 18, a perforated portion 19 or an under cut 20, and the knurl 12A.

[0034] The dome region 30 is surrounded by an upper portion-opened cylindrical outer wall 11, and includes a pressing plate 32 installed at an upper end of a hemisphere (dome) 31, a thin connection film 33 connecting the outer wall region and the hemispherical (dome) region. The thin connection film has at least one crease 34.

[0035] The cutting region 40 is installed at a lower inner portion of the dome region. The cutting region 40 has a cylindrical shape with a lower portion opened, and is installed in a vertical direction. The cutting region 40 includes a cutting support 41 required for penetrating and cutting a sealing member, a cutting blade 42, a cutting support blade 44 for slitting the sealing member, and a sealing member keeping recess 43 for keeping the slit sealing member.

[0036] A first embodiment of the present invention will now be described with reference to FIGS. 3 and 4.

[0037] A closure includes a wrapper installation jaw 16 installed at the inner surface or the outer surface of the outer wall (protecting wall) 11, a wrapper 15 mounted at the wrapper installation jaw 16, the spoon mounting jaw 14 installed at the inner surface of the outer wall 11, a spoon for scooping a content, a pressing plate 32 formed thicker than the connection film 33 of the dome region 30, a crease 34 allowing the connection film to be easily folded, a cutting blade 42 of the cutting region 40 penetrating the sealing member, a sealing member keeping recess 43 keeping the slit sealing member, and a cutting support blade 44 of the cutting support 41 for completely slitting the penetrated sealing member.

[0038] The closure according to the first embodiment of the present invention is applied to a container in which content 3 is put in a paste state, or content such as a thick solution or a powder product, which a user can have with a spoon.

[0039] A second embodiment of the present invention will now be described, in which the closure does not have such a spoon mounting jaw and a spoon as in the first embodiment of FIGS. 3 and 4.

[0040] Its operational order is as follows.

[0041] 1) The wrapper 15 mounted at the wrapper installation jaw 16 installed at an inner or outer surface of the outer wall (protection wall) 11, namely, a portion of the outer wall region 10 of the closure is removed by using fingers or other tools.

[0042] 2) The pressing plate 32 of the dome region is softly pressed by the thumb in a vertical direction downwardly.

[0043] 3) The thin connection film 33 is folded by virtue of the pressing force and the cutting region 40 also descends.

[0044] 4) The cutting blade 42 of the cutting region 40 installed at the lower side of the dome region 30 mounted at the inlet of the container descends to penetrate the sealing member 2, and at this time, the folded thin connection film 33 remains folded, not being recovered to its original state.

[0045] 5) The sealing member which has been penetrated by the cutting blade 42 is inserted in the sealing member keeping recess 43 (Refer to FIG. 4).

[0046] 6) In order to release the closure from the container, the closure is rotated in an opening direction.

[0047] 7) A portion of the sealing member 2 inserted in the sealing member keeping recess 43, which has survived the cutting and thus remained intact, if any, is cut by the sharp cutting support blade 44 installed perpendicular in the opening direction to the side of the cutting support 41 and inserted into the sealing member keeping recess 43 completely, and the slit sealing member 2A is kept in the sealing member keeping recess 43 of the closure.

[0048] The closure in accordance with the second embodiment of the present invention is applied to a container which holds a watery solution that users may have by applying their mouths to the container, or to a container having a content can be poured into a different container for a user to have, e.g., milk, watery yogurt, cafe latte, or the like. A third embodiment of the present invention will now be described.

[0049] In such a structure of the closure as in first embodiment, an open bar 46 for penetrating the sealing member to open it is installed at a lower portion of the pressing plate of the hemispherical region, and an upper space for storing content inside the hemispherical region is formed.

[0050] A fourth embodiment of the present invention will now be described.

[0051] FIGS. 11 and 12 illustrate installation of the cutting region 40 at an inner wall surface of the outer wall region, without having the hemispherical region 30. A closure in accordance with the fourth embodiment of the present invention operates as follows.

[0052] 1) A closure 4 coupled spaced with a certain interval 50 from the inlet of the container 1 with the sealing member 2 mounted therein is rotated (in case of a screw) in a closing direction and descends vertically by a pressing force (in case of an undercut) to be closed completely.

[0053] 2) The perforated portion 19 of the sealing portion 17 is torn off by virtue of the rotational force or the vertical descending force and the closure is tightly attached to the inlet of the container.

[0054] 3) The sealing member 2 is penetrated by the cutting blade 42 installed at the inner surface of the closure 4, cut by the cutting support blade 44 and completely separated from the inlet of the container 1.

[0055] 4) The completely slit sealing member 2A is released from the inlet of the container and inserted into the sealing member keeping recess 43.

[0056] 5) When the closure 4 is rotated in an opening direction, the connected portion 18 is torn and the perforated portion 17 is caught by a protrusion of the lower portion of a screw installed at an outer surface of the inlet of the container to remain there while the sealing member 2A is kept in the sealing member keeping recess 43. In this state, the closure 4 is released from the inlet of the container.

[0057] The closure is applied to a container which holds a content 3 in a paste state, or content such as a thick solution or a powder product which a user can have with a spoon.

[0058] As stated above, when the closure coupled at the inlet of the container 1 with the sealing member 2 mounted therein is opened, the sealing member 2 is automatically penetrated, slit and inserted for storage in the sealing member keeping recess 43 inside the closure.

[0059] In addition, the closure mounted at the inlet of the sealing-processed container which automatically keeps the sealing member 2A when it is opened can be applicable to any containers so long as they are sealing-processed regardless of a content, rather than being limited to the beverage container, and a design (or pattern) of the closure is to be interpreted to come within the coverage of the present invention.

INDUSTRIAL APPLICABILITY

[0060] As so far described, the closure with the push type opener in accordance with the present invention has the following advantages.

[0061] That is, for example, first, since the sealing member capping the container can be opened by the pressing method, a user cannot be bothered to separate the closure in order to remove the sealing member to take the content of the container.

[0062] Second, because the user can easily open the inlet of the container without applying hands to the inlet of the container in order to remove the sealing member to have a beverage or a content of the container, he/she can take the content hygienically.

[0063] Third, with a content stored inside the closure, the sealing member can be opened by the pressing method, and the content stored inside the closure and a content stored in the container can be mixed. Accordingly, the user can simply mix the different contents to have it.

[0064] Fourth, since the sealing member mounted at the inlet of the container is removed and automatically stored inside the closure, the slit sealing member does not remain as waste.

[0065] Finally, since a spoon or a straw can be kept in a space of an upper portion of the closure, a user can easily use them for having a content of the container, and in addition, by providing a closure cover, it accomplishes effectiveness of advertising as well as preventing introduction of foreign materials to thereby improve hygiene of the spoon or the straw.
