Description

[Detailed description of the invention] [Industrial application field] This invention is a novel cap for closing the opening part of a paper packaged beverage when the paper packaged beverage is opened, a portion is used, and the remaining part is stored. It is related to.

[Conventional technology and its problems]

Paper-packed beverages such as milk are 500ml.
There is a 1000 ml paper pack, and the paper pack is square tube-shaped, and the upper end opening is folded into a gusset over the required area, closed flat, and glued to make it completely sealed.The paper pack is opened by forcing the adhesive part of the gusset fold on one side to be sealed. It peels off and opens to allow the beverage to flow out.

By the way, once opened, a paper packaged beverage has a tendency to open at the opening, and it is not only sanitary to leave the mouth open, but also the liquid will spill out if the package is accidentally tipped over.

Therefore, the object of this invention is to provide a cap that can forcibly close the opening of an opened paper packaged beverage.

[Means for solving problems]

In order to solve the above problems, this invention consists of a plastic molded product that covers the upper opening of the beverage paper carton and the upper side of the rectangular tube that follows this opening. Both side walls are inclined in opposite directions and have an upright plate section at the upper end thereof, and an opening/closing knob at the upper end of the upright plate section, and one of the upright plate sections has a detent facing toward the other upright plate section. A hole into which the projection fits is provided in the other upright plate part, and at least a large part of the upper side of the square tube part is made thin in a required widthwise center area of the other opposing both side walls up to the upper end. This is a cap for beverages in an openable paper pack that can be compressed and expanded in the width direction.

[Effect]

The protrusion and the opposing upright plate portions of the cap, each of which has a hole into which the protrusion fits, are forcibly removed from the hole and both of the upright plate portions are separated by stretching the thin wall portion of the side wall. After covering the opened paper packaged beverage, the two upright plate sections are overlapped and the protrusions are forcibly fitted into the opposing holes, whereby both the upright plate sections clamp and close the unsealed portion of the paper packaged beverage.

〔Example〕

FIG. 1 shows an example of the cap for an opened paper packaged beverage according to the present invention, and FIG. 2 shows the cap attached to an opened paper packaged beverage, where 1 is the cap and 2 is the opened paper packaged beverage cap. It is a drink.

In the paper pack beverage 2, one of the opposite side walls at the upper end opening of the square tube part 3 is folded into a gusset (4 indicates the gusset folded part), and the upper ends 5 of the other opposite side walls are brought into contact with each other. is fixed with glue, including the gusset fold 4, and can be opened by expanding the gusset fold on one side and forcibly pulling it away from the adjacent side wall (halfway open).
can do.

In this unsealed state, the horizontal shoulder 6 between the rectangular tube portion 3 and the upper end 5 of the side wall, which is partially joined to the rectangular tube portion 3, is raised in an inclined manner as shown in the figure.

The cap 1 is a plastic molded product having a shape that covers the upper end opening (the joined side wall upper end 5) of the opened paper pack 2 and the upper side of the rectangular tube portion 3 following this, and the upper end of the rectangular tube portion 7 with the lower end open. One opposing side wall 8 is inclined in the opposite direction, and an upright plate part 9 is connected to the upper end thereof, and an opening/closing knob 10 is connected to the upper end thereof. opening (side wall 5 where the opening end overlaps)
It is bent to the opposite side and made vertical so as to release the thickness.

Also, one of the opposing upright plate sections 9 is engaged with a horizontally long protrusion 13 that fits into a horizontally long hole 12 formed in the other opposing plate section, and a detent bulge 14 is provided at the tip of the protrusion 13. is engaged.

The other opposing side walls of the rectangular tube portion 7 have a thinned portion 15 in a required range at the center in the width direction, and this thinned portion is formed as a bellows fold 16 to enable compression and expansion.

This cap 1 covers the opened paper pack 2 with the opposing upright plate parts 9 separated from each other, and the lower half portion 11 of the opposing upright plate part 9 of the cap covers the opposing side walls 5 at the opening of the paper pack.
In this state, the protrusion 13 is fitted into the hole 12 and supported, thereby forcibly closing the unsealed portion of the paper pack 2.

FIG. 3 shows another example of the cap, and this cap 1a has a thin wall portion 1 formed on the other side wall of each cylindrical portion 7.
5a has a concave shape with a downward width, and the upper side except for the lower end has fan-shaped bellows folds 16a.

The thinned side wall of the rectangular cylindrical part of the cap can be compressed and expanded not only by bellows folds, but also by a hinge that curves outward or inward into a semi-cylindrical shape, or a single chevron-shaped hinge that points outward or inward. , it is also possible to use a hinge whose circumferential surface of the semi-cylindrical shape is enlarged and whose cross section is cylindrical in the shape of "Ω", which is an electrical resistance symbol, or it can be made into a hinge that is simply made thinner. can.

〔effect〕

The use of this invented paper pack beverage cap has the following effects.

(1) This cap covers the upper opening of the opened paper carton beverage and the upper side of the rectangular tube part that follows this, and the part that covers the opening of the paper carton is an opposing upright plate part, and one of the caps has an opposing side. A protrusion with a detent is provided on the other side, and a hole into which the protrusion fits is provided on the other side.By joining both upright plate parts, the opening part of the paper pack becomes the original gusset fold shape, and the paper pack can be opened by pinching it. section is closed.

(2) This cap is a molded plastic product.
In addition, the wall surface adjacent to the surface where the upright plate portions of each cylindrical portion are connected is made thin in the required range in the width direction central portion, so that compression and expansion in the width direction is possible. It is easy to separate and approach the plate part.

(3) Since a knob for opening and closing the plate is provided at the upper end of the upright plate, it is easy to open and close both the upright plates.
