Description

Container cap {CAP FOR CONTAINER}

The present invention relates to a cap for a container, and more particularly, to a cap for a container having an improved structure so as to improve the opening convenience of the cap for a container.

In general, a container in which a liquid is accommodated is provided with an openable container cap coupled to an open inlet, and the container cap is sealed so that it can be checked whether or not it is first opened. This sealing cap is to prevent the contents from being damaged, such as the contents contained in the container being altered by arbitrary opening.

In general, a container that maintains a sterile state, including an injection solution, a potion for internal use, or other medicinal solution, is sealed to prevent deterioration and leakage of the contents stored inside, and to block the inflow of foreign substances from the outside. Various forms are being developed to enhance convenience.

Such a container may be composed of borosilicate glass, which is glass used for beverages, etc. depending on the purpose of use, and may be composed of a colorless and transparent brown glass to which iron oxide is added to reduce the effect of light.

On the other hand, the container may be sealed by melting the upper glass with heat after storing the contents therein, or may be sealed by providing a separate cap.

Caps used for containers are variously configured in consideration of efficiency and convenience of use, and an example of such a cap is shown in FIG. 1 .

1 is a view showing an example of a general container cap.

1, a container 10 having a space to store the contents therein, a rubber stopper 20 sealing the opening of the container 10, and a cap 30 surrounding the outside of the rubber stopper 20 ) is composed of Here, the cap 30 is composed of a cover 31 made of a synthetic resin material to form an upper layer of the cap 30 and a sleeve 32 made of an aluminum material to form a lower layer of the cover 31, the cover The central portion of (31) is fixedly coupled to each other by a coupling portion (33) extending downward. In addition, a perforation line 34 is formed on the surface of the sleeve 32 to facilitate the cut when the cover 31 is removed. On the other hand, the cap 30 is put on the outside of the rubber seal 20 and the lower end of the sleeve 32 positioned around the opening is clamped and sealed, and then the contents are sterilized.

Figure 2 is a view showing the opening process of the cap for the container in Figure 1.

In FIG. 2 , when the cap 30 for a container pulls the cover 31 in the open direction through a finger or a tool (opener), as shown in (a), the cover 31 is separated from the sleeve 32 while open first. At this time, as shown in (b), the perforated line 34 of the sleeve 32 is separated from the sleeve 32 in a state of being fixedly coupled to the central portion of the cover 31 through the coupling portion 33 . Then, when the sleeve 32 is completely torn off, as shown in (c), the rubber seal 20 is completely exposed to the outside.

However, in case of pulling the cover 31 and pulling the sleeve 32 in the opposite direction to the opening direction of the cover 31 to open the cap 30 when using the container, it is completely separated from the sleeve 32. There is a problem in that only the cover 31 falls out and the cap 30 cannot be opened. In this case, there is an inconvenience of having to open the cap 30 by tearing the sleeve 32 using a separate tool. In addition, in the case of the elderly or women, it may be somewhat difficult to open the cap 30 only by hand.
