DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a straw, and more particularly to a straw for sucking a beverage sealed in a container into a mouth and a sealed container provided with the straw.

[0002]

When drinking a beverage sealed in a container, a straw is used to pierce the container.
Since the straw has no resealability, the beverage in the container must be drunk at a stretch. If the container falls down with the beverage left in the container, the beverage will spill through a straw or through a straw hole. Further, if the straw is left for a long time while piercing the container, there is a hygiene problem in the suction port of the straw and in the periphery of the straw hole.

An object of the present invention is to provide a straw and a sealed container with a straw which have solved the above-mentioned problems, provided the straw with resealability, and solved the problem of hygiene.

SUMMARY OF THE INVENTION A straw according to the present invention has a first end serving as a suction port and a second end serving as a suction outlet, and a seal cap is detachably attached to the second end. It is covered with.

In the straw according to the present invention, when the straw is pierced into the container with the first end first and the cap is removed from the second end of the straw, the beverage in the container can be sucked into the mouth by the straw. If there is any leftovers, the container can be resealed by placing a cap on the second end of the straw. Moreover, the second end portion serving as the straw suction port can be kept clean by the cap.

If the straw is provided with a sealing flange on the outer surface of the straw, and the straw is pierced into the straw hole of the container, the straw can be kept in a stable posture by contacting the flange around the straw hole. .

Further, if the straw and the flange are formed by separate members, and the flange is movable in the length direction of the straw, the length of the straw piercing the container can be adjusted.

Further, if an adhesive layer is formed on one side of the flange facing the first end, and the adhesive layer is covered with an annular release sheet, the release sheet is peeled off and the adhesive layer is inserted into a straw hole. By gluing around the straw, the straw can be firmly fixed to the container. Moreover, the gap between the straw hole and the straw can be sealed by the flange, and the leakage of the beverage from the straw hole can be prevented.

Further, when the release sheet is formed by a plurality of divided pieces connected in the circumferential direction, the peeled release sheet can be easily removed from the straw.

[0010] The straw is attached to a sealed container, and the container preferably has a straw hole. In that case, the adhesive layer may be formed on one surface of the flange, or may be formed on the outer peripheral surface of the straw hole.
