Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a lid of a container for storing liquid beverages such as juice, beer, sake, drinking water and foods such as granules.

[0002]

2. Description of the Related Art A conventional lid is provided with a heat seal layer such as ethylene vinyl acetate copolymer (EVA) or ethylene ethyl acrylate copolymer (EEA) below a synthetic resin film such as polyethylene (PE). Commonly used.

[0003]

[Devised Problems to be Solved] In this conventional lid was sealed by heat sealing a container containing, for example, a juice as a storage material with a lid, all peeling technique <br/> taken from the container and the lid when the consumer to drink When drinking, the opening of the container is too large and the juice spills
There was a problem that it was easy to drink and it was difficult to remove it. Also, if one part of the lid was peeled off and one part was opened and one part of the lid was bent over the remaining lid, the lid that was peeled off and bent upward There is a problem that it is unpleasant and extremely difficult to drink when hitting the face such as the nose of a drinker.

[0004] The present invention solves these problems of the conventional lid, partially opening the lid, making it easy to drink liquid beverages such as juice, beer, sake, drinking water, and granules. The purpose is to make food easier to eat.

[0005] The partially open lid of the present invention is provided with a heat sealing layer below the uniaxially stretched synthetic resin film or the biaxially stretched synthetic resin film, and fills the lid made of this film.

Function: The upper opening of the container is sealed by heat sealing with a partially open lid, and the lid is easily torn in the film stretching direction during eating and drinking, so take a picture of the lid by hand and tear the lid from the cut. As a result, the lid is first torn smoothly from the cut edge in the stretching direction with a small force, and then about 1/4.
Heat-sealed portion is small, which is heat sealed to the arcuate

BRIEF DESCRIPTION OF THE DRAWINGS FIG. As shown in FIGS. 1 and 2,
1 Direction Ru provided a heat sealing layer 2 of uniaxially oriented polyethylene stretched in (longitudinal direction indicated by the arrow in FIG. 1) (PE) Ethylene vinyl acetate copolymer on the lower side of the film 1 (EVA). From this stretched synthetic resin film
Direction perpendicular to the stretching direction of the uniaxially stretched synthetic resin film
From the central outer edge 5 ', which is the maximum width of the lid, to about 1/4 of the width of the lid
The outer edge 5 ″ of the lid, ie, the left front outer edge 5 ″ in FIG.
Then, a piece 3 of the lid that is continuous with the lid is
It is provided so as to project in the same direction as the film stretching direction.
Further, the tip 4 'of the cut is uniaxially extended on the taking piece 3 of the lid.
Reverse V oriented in the same direction as the stretch direction of the stretched synthetic resin film
This is a partial opening lid 5 provided with a triangular cutout 4 in the shape of a letter .

When the partial opening lid 5 of this embodiment is actually used, as shown in FIG. 3, for example, juice is put in a container 6 and the partial opening lid 5 with the shooting piece 3 provided with the cutout 4 is placed in the container. The upper opening of the container 6 is heat-sealed with the heat sealing layer 2 to seal the opening of the container 6. When the consumer drinks the juice, the user takes a photographing piece 3 on the left side of the lid 5 on the drawing with his fingertip and lifts a part of the lid 5 (the left side in FIG. 3) above the container 6. Tip 4 of cut-out 4 in triangular shape
'Tear in the stretching direction of the film 1 from the next while heat-sealed portion which is heat-sealed to the upper opening of the container 6 are destroyed, about 1 of the container 6, as shown in FIG. 3 /
4 is opened. Approximately 1/4 of this drinks the juice put in the container 6 from the part where the opening 7 is opened. Then, if necessary, when the container 6 has a small amount of storage, the remaining photographing piece 3 (right side in FIG. 3) is photographed, the remaining lid 5 is removed, and all the lids 5 are peeled off from the container 6. After the entire container 6 is opened, the remaining contents of the container 6 may be consumed. In this example, a polyethylene (PE) film was described as a uniaxially stretched film, but a polypropylene (P) film was used as a uniaxially stretched film in addition to a polyethylene (PE) film.
P) film, polyvinyl chloride (PVC) film, polystyrene (PS) film and the like are preferable.

FIG. 4 and FIG. 5 show another embodiment, in which a polyethylene adhesive layer 12 is provided under a uniaxially oriented polypropylene (PP) film 11 which is stretched in one direction (the direction of the arrow shown in FIG. 4). A heat seal layer 13 of ethylene ethyl acrylate copolymer (EEA) is provided below the adhesive layer 12. A polyethylene adhesive layer 14 is provided on the upper side of the film 11, an aluminum foil layer 15 is provided on the upper side of the polyethylene adhesive layer 14, and a photographing piece 16 is provided in a direction in which the film 11 extends. The tip 17 'of the triangular cut 17 having a deformed inverted V-shape is turned in the same direction as the extending direction, and the left side of FIG.
Triangular shape on the shooting piece 16 about 1/4 of the width of the lid from the edge
It is a partial flaps 18 provided with the cut 17. In this other example, a partially open lid using a uniaxially stretched polypropylene film was described. However, instead of the uniaxially stretched film, biaxially stretched polyethylene (PE) stretched in one direction and in a direction perpendicular to one direction is used. ) A partially open lid using a film may be used, or the aluminum foil layer may be provided below the uniaxially oriented polypropylene (PP) film. Also, as shown in FIG.
Approximately 3 composed of one side parallel to the stretching direction
It may be square-shaped cut 21. As shown in FIG. 7, the cut piece 24 of the slit parallel to the extending direction may be formed on the photographing piece 23 of the partial opening lid 22, and the partial opening lid 22 has a thickness of 15 μm and one direction as shown in FIG. 8. The aluminum foil layers 28 and 29 having a thickness of 7 μm are provided on both sides of the lower and upper sides of the uniaxially stretched polyethylene (PE) film 25 through the adhesive layers 26 and 27, respectively. Is a partial opening lid 22 provided with a heat seal layer 31 of ethylene ethyl acrylate copolymer (EEA) below an adhesive layer 30 via an adhesive layer 30. When the partial opening lid 22 is torn linearly in the stretching direction of the uniaxially stretched polyethylene (PE) film 25, the thin aluminum foil layers having a thickness of 7 microns provided on the upper and lower surfaces of the PE film are small in strength. Can be torn linearly and smoothly without the aluminum foil layer preventing the film from being torn in the stretching direction, and the aluminum foil layers can be partially opened by providing the aluminum foil layer on both the upper and lower surfaces of the PE film. It is possible to prevent the lid 22 from curling upward or downward.

[0010]

[Effects of the Invention] The partially open lid of this invention takes a photograph piece provided on the lid, extends from the cut edge of the lid, and makes the lid easy to tear.
First, you can tear smoothly with a small force.
Approximately 1/4 of the heat-sealed part is broken smoothly with a small force
About 1/4 of the lid while tearing the lid while cutting
And a lid provided at the upper opening of the container
Can be smaller by about 1/4 . like this
In a liquid beverage zero Succoth without such juice in containers about 1/4 as small as the opened opening the lid, to be able to smoothly drink, from the opening with a reduced opening the lid by approximately 1/4 the food products such as granular housed in container can eat smoothly taken out One not a little.
