Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper container in which a synthetic resin film is stuck on the entire inner surface to store prepared foods and the like.

[0002]

2. Description of the Related Art As a conventional example suitable for comparison with the present invention, there is a paper container shown in FIG. The paper container is formed by bending the inner and outer plates 3 and 5 connected to the bottom plate 1 inward and outward and stacking them, and inserting flaps 7 and 9 provided on both side plates.
Is inserted between the overlapped upright plates of the outer plates 3a and 5a, which are orthogonal to this.

[0003]

In the paper container described in the above prior art, one side of one of the flaps 9 is cut by a cut S to allow the flaps 7 and 9 to move when inserted.
Although it is common to separate the film from a, the problem is that this separation inevitably causes the film to be cut along with the cut S, causing the cut film portions to overlap, causing juices such as prepared foods to leak from the overlapping portion. There are drawbacks.

In view of the above, an object of the present invention is to provide a structure in which a container can be assembled without cutting a film, and to eliminate a defect such as a juice leak which has conventionally occurred.

[0005]

In order to achieve the above object, the present invention provides a paper plate A and a base plate C in which a synthetic resin film B is adhered to one entire surface of the paper plate. Inner plates 3 and 3a connected to the respective sides of the bottom plate 1 via respective creases 2 and 2a parallel thereto; and creases 4 parallel to the creases 2 and 2a on the inner plates 3 and 3a. 4a, outer flaps 7 connected to an end of the outer plate 5 via a crease 6, and a crease 8 provided at an end of the inner plate 3. in paper container composed of the insertion flap 9 inside which is continuously provided via a plug flaps 9 of the inner, all of paperboard portion of the back side thereof leaving only film B ₁ part of the flap portion or excised part, essential to become to face the film B ₁ part concealed form in the space caused by the excision To the effect.

[0006]

FIG. 1 shows an expanded state of a paper container.
A paper plate A and a base plate C in which a synthetic resin film B is adhered to one entire surface of the paper plate are provided on a bottom plate 1 and each side of the bottom plate 1 via folding lines 2 and 2a parallel thereto. Inner plates 3, 3a connected to each other, and outer plates 5, 5a connected to the inner plates 3, 3a via folding lines 4, 4a parallel to the above-mentioned folding lines 2, 2a;
An outer insertion flap 7 connected to an end of the outer plate 5 via a folding line 6 and an inner insertion flap 9 connected to an end of the inner plate 3 via a folding line 8 are provided. in configured paper containers, insertion flap 9 of the inner, the leaving only film B ₁ part of the flap portion excised all or part of the paper plate portion of the rear side, caused by the resection space it is made to face the film B ₁ part concealed form.

[0007]

[Operation of the invention] The assembling method is as follows:
By folding and gluing the inner plates 3, 3a, 5, 5a inward and outward along 4a, double side walls are formed upright on four sides, and the inner and outer flaps 7, 9 are inserted. Origami 6,8
It is no different from the general form of this type of container in which a container as shown in FIG. 5 is assembled by folding the flaps together and inserting them into orthogonal standing side walls,
In particular, the features of the present invention are as follows.

That is, the inner and outer flaps for insertion 7 and 9
Of, the flaps 9 are excised all the paperboard portion of the back side thereof leaving only film B ₁ corresponding to the flap 9, among the film B ₁ standing state, the outer plate 3a,
The plugged between 5a, approximately half the length range of the film B ₁ of the flap 7 closer glued to the flap 7, when plugged flap 7 in this state, the inner plate 3 that have not been glued
film B ₁ part of a pro is among naturally, the outer plate 3a, 5
a between the inductively 3, pushed as shown in FIG. 4, pushed the film B ₁ moiety inner to form folded pleats, the outer plate 3a, 5
The cause of juice leakage is eliminated because it is interposed between "a" and is in a state of being folded in a folded shape. The flap 7 is, of course, adhesively fixed between the inner and outer plates 3a, 5a.

FIG. 6 shows a second embodiment. In this example, leaving a approximately half the area range of the inner plate 3 side of the flap 9, is excised and the remaining range, the covering of this cut portion in film B _1, the flap 7, the residual flap 9 preparative polymerization adhered previous example similar in a state, the outer plate 3a, if put difference between 5a, film B ₁ represents naturally inductively pushed, among interposed shaped folded outer panel 3a, in 5a, The cause of juice leakage can be eliminated.

[0010]

According to the present invention as described above, the following effects can be obtained. (A) an inner bayonet flap 9, leaving only film B ₁ corresponding to the flap, excised all or part of the paperboard portion of the back side thereof, the film B ₁ part space formed by the cut The film B can be interposed between the side plates 3a and 5a in a foldable manner with a very simple structure that allows the film to be concealed. Can be. (B) side plate 3a of the flap 7, since the film B ₁ is well follow during insertion between 5a can measure also the insertion operability of easy reduction.
