JP5437702B2 - Cover cover having insertion hole for reverse stretchable straw and food / beverage product package covered with cover cover - Google Patents

Description

The present invention is a double expansion / contraction straw, a cover for a beverage container in which a reverse expansion / contraction straw having an insertion tip formed obliquely at the tip of a thick outer straw and having a proximal drinking mouth on a thin inner straw is used. And it is related with the covering lid which has the insertion slot of the said reverse expansion-contraction straw.
Moreover, this invention relates to the food-drinks package using the said covering lid.

The said reverse expansion-contraction straw is well-known (for example, patent document 1).
The reverse stretchable straw has recently been used and put into practical use because it is easy to drink depending on the contents of the beverage container.
This beverage container is generally filled with a liquid container in a paper or plastic container, and the opening of the container is sealed with an aluminum foil, and a covering lid is placed on the container, and a straw slot is formed on the covering lid. Is formed. The reverse expansion / contraction straw is inserted into the straw insertion port, the aluminum foil is punched out, and the contents of the beverage container are drunk.

JP-A-62-192123

The shape of the straw insertion opening formed in the cover lid is circular, and there is a connection portion where a cut is not formed in a part thereof, or a U-shape.
Therefore, after inserting the reverse expansion / contraction straw into the insertion slot, drinking the beverage in the container, and then trying to extract the reverse expansion / contraction straw, the state where it was extracted halfway in the direction of the upward arrow is shown in FIG. Is bent into the container, and the tip of the tongue piece is locked to the boundary between the thick outer straw and the thin inner straw.
As a result, after drinking the beverage in the container, the reverse stretchable straw is put on and covered with the lid, and therefore, when pulling out from the container, there is a problem that the straw is locked by the locking portion and cannot be pulled out. In addition, if the reverse stretchable straw is forcibly pulled out, there is a problem that when it is pulled out, the beverage adhering to the reverse stretchable straw is scattered and the clothes are soiled.

In order to solve the above-mentioned problems, the present invention provides a novel cover that can easily pull out the reverse expansion / contraction straw inserted into the cover opening.
For this purpose, the covering lid having the insertion port for the reverse expansion / contraction straw according to the present invention forms a tongue-like slit forming the insertion port for the reverse expansion / contraction straw formed on the upper surface of the lid, and the tip of the tongue-like slit Ri Oh provided outwardly slit extending outwardly in communication with the tongue-like slits in the side, facing the inner in communication with the tongue-like slits on the distal end side of the tongue formed by the tongue-shaped slit An inward slit extending to the surface is provided .

The tongue-like slit has a circular shape or a U-shape that is not partially connected.
The outward slit extending outward is one or two linear slits.
The length of the outward slit extending in the outward is Ru 2~4mm der.

The covering lid having the insertion port for the reverse expansion / contraction straw according to the present invention has a tongue-like slit that forms a insertion piece for the reverse expansion / contraction straw formed on the upper surface of the cover lid, and the tip side of the tongue-like slit has the above-mentioned Ri Oh provided outwardly slit extending outwardly in communication with tongue slit, among which extends inwardly in communication with the tongue-like slits on the distal end side of the tongue formed by the tongue-shaped slit Since the slit is oriented, when pulling out the reverse expansion / contraction straw from the straw insertion port of the lid, a tongue-like shape is formed at the step part at the boundary between the thin inner straw and the thick outer straw of the reverse expansion / contraction straw Even if the tip of the tongue that forms the straw slot is locked, the reverse telescopic straw is pushed by the tongue toward the lateral side of the tongue, that is, toward the outward slit that extends outward. Greatly opens the straw spigot pushes open outward slit extending in the outward, there is an effect that can facilitate extraction of the inverse stretch straw.
Moreover, since the reverse expansion / contraction straw can be easily pulled out, there is no possibility that the beverage adhering to the reverse expansion / contraction straw does not scatter when it is pulled out and the clothes are soiled.

Hereinafter, embodiments of the present invention will be described in detail. 1 to 6 are reference examples, and FIGS. 7 and 8 are examples of the present invention. First, after describing the reference examples, the examples of the present invention will be described. FIG. 1 and FIG. 2 show a cover lid having a slot for a reverse expansion / contraction straw. In the figure, reference numeral 1 denotes this covering lid, and a tongue-like slit 3 is formed at an appropriate position on the upper surface 2 to form a slot for a reverse expansion / contraction straw. The basic portion of the tongue piece 4 formed by the tongue-shaped slit 3 is a portion where the slit is not connected. When the reverse expansion / contraction straw is inserted, the basic portion is bent and the tongue piece 4 is pushed downward. An outwardly extending slit 5 connected to the tongue-like slit 3 is formed on the tip side of the tongue-like slit 3.

FIG. 9 shows a reverse expansion / contraction straw, and FIG. 10 shows a state where the reverse expansion / contraction straw is covered and inserted into the insertion port of the upper surface 2 of the lid 1.
The reverse expansion / contraction straw is composed of a thick outer straw 20 and a thin inner straw 21, provided with a sharply cut sharpened portion 22 for insertion at the distal end of the outer straw 20, and a narrowed portion 23 at the proximal end of the outer straw 20. The distal end of the inner straw 21 has an enlarged diameter portion 24 that is in close contact with the narrowed portion 23 of the outer straw 20, and the proximal end is a drinking mouth portion 25.

  The reverse expansion / contraction straw is stretched so that the narrowing portion 23 of the outer straw 20 and the enlarged diameter portion 24 of the inner straw 21 are in close contact with each other, pierced into the insertion port of the top surface 2 of the cover lid 1, and the beverage in the container is drunk. When the reverse expansion / contraction straw is pulled up in the direction of the arrow in FIG. 10 to pull out the expansion / contraction straw, the tongue piece 4 formed on the upper surface 2 of the cover lid 1 is engaged with the step portion 26 at the boundary between the outer straw 20 and the inner straw 21. I can't escape. Even in such a situation, it is the cover of the present invention that makes it easy to pull out the reverse expansion / contraction straw.
