Container cap

Abstract

Disclosed herein is a container cap allowing the addition of an adjunct. The container cap includes a base cap member, which is a lower cap body coupled to a neck part of a container, an operational cap member, which is an upper cap body coupled to the upper end of the base cap member, and an openable sheet, which is provided on the lower end of one selected from the base cap member and the operational cap member. The openable sheet is able to be cut to discharge the adjunct. The container cap further includes a cutting means for cutting the openable sheet. The cutting means is provided in a remaining one selected from the base cap member and the operational cap member at a position corresponding to the openable sheet. The openable sheet includes a weight member, which has a diameter less than a diameter of an arc part of the openable sheet to be cut. A connection rib is connected between the weight member and a lower edge of an adjunct receiving part of the base cap member. The openable sheet further includes an openable sealing film, which seals both the lower edge of the adjunct receiving part and the weight member.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

FIG. 5 is a sectional view illustrating a container cap according to the preferred embodiment of the present invention. FIG. 6 is a sectional view of a critical part of the container cap of the present invention.

As shown in the drawings, the container cap of the present invention includes a base cap member 100, which is coupled to an opening of a container, an operational cap member 300, which is coupled to the upper end of the base cap member 100 and a cutting blade 3, and an openable sheet, which is the bottom of an adjunct receiving part 77-3. The openable sheet includes a weight member 77, which has a diameter less than that of an arc part, along which the bottom of the adjunct receiving part 77-3 is cut, at least one connection rib 77-2, which connects the weight member 77 to the lower edge of the adjunct receiving part 77-3, and an openable sealing film 777, which seals both the lower edge of the adjunct receiving part 77-3 and the weight member 77.

Furthermore, a band-shaped space 77-1 is defined between the lower edge of the adjunct receiving part 77-3 and the circumferential outer edge of the weight member 77, so that the cutting blade 3 of the operational cap member 300 is moved along the band-shaped space 77-1 without resistance when a cutting process is conducted.

The connection rib 77-2, which is connected between the lower edge of the adjunct receiving part 77-3 and the circumferential outer edge of the weight member 77, is provided in the band-shaped space 77-1.

Preferably, the weight member 77 has an appropriate weight such that, when the openable sheet is opened, the weight member is integrally rotated downwards along with the openable sealing film 777 around the connection rib 77-2, which serves as a hinge. Of course, because the openable sealing film 777 is integrated with the weight member 77, the openable sealing film 777 is prevented from being cut to shreds, thereby preventing part of the openable sealing film 777 from falling into the contents in the container.

In the present invention having the above-mentioned construction, when a user moves the cutting blade 3, which is integrally coupled to the operational cap member 300, downwards using the operational cap member 300, the openable sealing film 77, which is exposed through the band-shaped space 77-1, defined between the weight member 77 and the lower edge of the adjunct receiving part 77-3 of the base cap member 100, is easily cut by the cutting blade 3. As such, because the openable sealing film 777 can be easily cut using only a relatively small force, an old person or a child can easily use the container cap of the present invention.

Furthermore, when the cutting blade 3 cuts the openable sealing film 777, which is attached to the weight member 77, along the band-shaped space 77-1, as shown in FIG. 7, the weight member 77 and the openable sealing film 777 are rotated together downwards around the connection rib 77-2, serving as the hinge, so that the adjunct falls outside the adjunct receiving part 77-3 through the opened band-shaped space 77-1 and is added into the contents in the container.

As such, because the openable sealing film 777 is integrally attached to the weight member 77, when the part of the openable sealing film 777 that corresponds to the band-shaped space 77-1 is cut, even if it is cut to shreds, the cut shreds of the openable sealing film 777 maintain the state in which they are attached to the weight member 77, thus preventing the cut shreds of the openable sealing film 777 from falling into the contents in the container and preventing the user from drinking foreign substances.

In addition, when cutting the openable sealing film 777, the weight member 77 is rotated downards along with the openable sealing film 777 around the connection rib 77-2 as the hinge. In other words, thanks to the weight member 77, serving as a weight, the openable sheet is smoothly opened, thereby the adjunct can be easily discharged from the adjunct receiving part 77-3.

Meanwhile, in the present invention, only one connection rib 77-2, which connects the weight member 77 to the lower edge of the adjunct receiving part 77-3, need be provided in the band-shaped space 77-1. Alternatively, several connection ribs 77-2 may be provided at adjacent positions spaced apart from each other at regular angular intervals. That is, it is preferable that one or more connection ribs 77-2 be selectively provided, as necessary.

As described above, in a container cap according to the present invention, an openable sheet, which closes the open lower end of an adjunct receiving part, includes a weight member, which has a diameter less than the inner diameter of the adjunct receiving part such that a band-shaped space is coaxially defined between the weight member and the adjunct receiving part. Furthermore, both the weight member and the lower edge of the adjunct receiving part, which define the band-shaped space therebetween, are sealed by a separate openable sealing film, such as an aluminum film, thus providing the superior sealing ability unique to aluminum.

In addition, the present invention is constructed such that the adjunct receiving part is opened by cutting part of the openable sealing film, which is exposed through the band-shaped space defined by the difference between the diameter of the weight member and the inner diameter of the adjunct receiving part. Therefore, the adjunct receiving part can be easily opened by only a relatively small force, so that even children can easily use the present invention. In other words, the present invention can be easily used without limitation of users.

Furthermore, although the separate openable sealing film, such as an aluminum film, is used in the present invention, because the openable sealing film is integrally attached at the central portion thereof to the weight member, the openable sealing film is prevented from being cut into shreds, thus fundamentally preventing the user from suffering displeasure attributable to the presence of foreign substances when drinking the contents of the container, thereby ensuring the reliability of the product.

Moreover, in the present invention, when the adjunct receiving part is opened to add the adjunct into the contents, the weight member and the openable sealing film, which are integrated with each other, are rotated downwards around the connection rib, which serves as a hinge. Thus, the user can directly observe the process of adding the adjunct into the contents. Therefore, the present invention stimulates the curiosity of consumers, thus arousing consumers' interest.

Although the preferred embodiment of the present invention has been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
