Description

[0001]
[Industrial application fields]
The present invention relates to a container lid, and more particularly to a container lid that covers an opening of a container body.
[0002]
[Prior art]
Metal cans are used to fill and supply various beverages. That is, a container made of an aluminum alloy or a steel plate, in which a cutting guide portion is formed at the lid portion, and a pull tab is attached to the cutting start position of the cutting guide portion is used. When drinking a beverage in such a container, the pull tab may be pulled to open the lid spout.
[0003]
[Problems to be solved by the invention]
According to the conventional container made of such a metal can, the spout is formed by pulling the pull tab and breaking the cutting guide portion of the lid. Therefore, when drinking the beverage which is the contents directly from the container of such a metal can, the lips touch the portion around the broken spout. Therefore, when the atmosphere in which such a metal can is placed is unclean, it is a sanitary outer surface of the metal can, and it comes in contact with the mouth around the spout, which is not hygienic.
[0004]
Although it may be considered to clean the portion corresponding to the spout with a cloth before opening, it is very troublesome. Further, the metal can must be crushed when it is discarded, and there is a disadvantage that the disposal process becomes troublesome. Furthermore, a container made of a metal can has a drawback that it is heavy.
[0005]
In view of such a problem, it is considered that a beverage is filled and supplied with a paper cup-shaped container. However, a normal cup-shaped paper container (paper cup) can be detachably fitted with a synthetic resin lid, but cannot be supplied with a virgin seal. It is used in vending machines that dispense beverages.
[0006]
The present invention has been made in view of such problems, and a clean spout is exposed at the time of opening, and it is not necessary to bother crushing at the time of disposal, and can be easily disposed of. An object of the present invention is to provide a lid for the container.
[0007]

A cutting guide portion is formed on the paper sheet so as to surround the peripheral edge of the spout at a position outside the cutting guide portion of the plate-like portion, and the cutting start position of the plate-like portion and the sheet is By pulling a pull tab provided in the vicinity, the cutting guide part of the plate-like part and the cutting guide part of the sheet are both broken to form a spout and sealed in an area surrounded by the cutting guide part of the sheet Is A had flat portions portions lips are in contact with those who to be exposed.
[0008]
In particular, in the present invention, the region surrounded by the cutting guide portion of the paper sheet is configured to seal in advance the portion around the spout of the frame portion where the lips come into contact. When the cutting guide part and the sheet cutting guide part are broken, the part around the spout of the frame part, particularly the part in contact with the lips, is exposed for the first time.
[0009]
In addition, a pull tab is connected to substantially the center of the lid, and an approximately isosceles triangular spout is formed on the lid with the connecting position of the pull tab as a vertex, thereby forming a very easy-to-drink spout. Thus, air is introduced into the container through the isosceles triangle shaped spout while drinking, and the container can be smoothly poured out.
[0010]
[Action]
When the pull tab connected to the vicinity of the cutting start position of the plate portion and the sheet is pulled, the cutting guide portion of the plate portion and the cutting guide portion of the sheet are broken together. Then, the spout is formed by the breakage of the cutting guide part of the plate-like part, and the region surrounding the peripheral part of the spout is exposed by the breakage of the cutting guide part of the sheet.
