Abstract

PROBLEM TO BE SOLVED: To enable a synthetic resin bag to be attached without using an adhesive tape or the like in a box with the synthetic resin bag attached therein by providing a cut for hooking an upper part of the synthetic resin bag at both end rims of one of lid pieces foldably provided on an upper part of respective opposite side plates. SOLUTION: The box 1 is made of corrugated fiberboard and comprises opposite short side plates 3a and long side plates 3b, a bottom plate provided on a lower part of the respective short side plates 3a and the long side plates 3b for closing a lower opening and lid pieces 1a, 7b provided on an upper part of the respective short side plates 3a, the long side plates 3b for closing an upper opening. In this case, a cut 11a for attaching a synthetic resin bag 9 to be put inside is formed close to the short side plates 3a at both end rims of the lid piece 7a provided on the upper part of the short side plates 3a. Each cut 11a is formed to be inclined from both ends of the lid piece 7a in inward and downward directions. When the synthetic resin bag 9 is attached inside the box 1, upper parts of the synthetic resin bag 9 are fitted into the opposite cuts 11a, respectively for hooking and fixing.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box with a synthetic resin bag, and more particularly to a structure for attaching a synthetic resin bag.

[0002]

For example, a box made of corrugated paper having a one-touch assembly structure in which a part of a bottom piece provided at a lower portion of an opposing side plate is adhered and engageable, or provided on an opposing side plate. For boxes made of corrugated paper, etc., which are assembled by engaging the bottom pieces with each other, it is necessary to prevent the moisture and odor of the stored material from leaking to the outside, or to prevent the external moisture from penetrating the corrugated paper and adhering to the stored material. To prevent this, a synthetic resin bag is attached inside the box along the inner surface of each side plate.

[0003] As a method of mounting the synthetic resin bag, an end is adhered to a lid piece provided on an upper portion of an opposing side plate with an adhesive tape or the like in a state where the upper portion of the synthetic resin bag is folded back and hooked. However, in this mounting method, it takes time and effort to mount the box, and the production cost of the box is high. Depending on the contents, the synthetic resin bag may not be necessary.However, in order to remove the synthetic resin bag, the adhesive tape must be peeled off so that a part of the corrugated paper does not come off. I was

Further, it is necessary to use a synthetic resin bag to be attached that is larger than the height of the upright side plate and the lid piece, and the cost of the synthetic resin bag is high.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional disadvantages, and an object of the present invention is to provide a box with a synthetic resin bag which can reduce the manufacturing cost. .

Another object of the present invention is to provide a box with a synthetic resin bag which can be easily removed without damaging the box.

It is another object of the present invention to provide a box with a synthetic resin bag which can be manufactured at a reduced cost by using a small synthetic resin bag.

[0008]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a synthetic resin bag which can be attached along its inner surface in a box in which a lid piece is provided on the upper side of each of the opposing side plates so as to be bent. In the attached box, cutouts are provided at both side edges of one of the opposing lid pieces to hook the upper portion of the synthetic resin bag to be mounted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view schematically showing a box with a synthetic resin bag.

FIG. 2 is a perspective view showing a modified example of the bottom plate.

FIG. 3 is a front view showing the engaging portion.

FIG. 4 is a perspective view showing a modified example of the engaging portion.

FIG. 5 is a perspective view showing a modified example of the engaging portion.

The box 1 is made of corrugated cardboard and has opposing short side plates 3.
a · 3a, long side plates 3b · 3b, and each short side plate 3a · 3a,
A bottom plate 5 provided below the long side plates 3b, 3b to close the lower opening and each of the short side plates 3a, 3a, and lid pieces 7a, 7a provided above the long side plates 3b, 3b to close the upper opening;
7b and 7b. Note that the corrugated paperboard constituting the box 1 may be non-waterproof, or may have a waterproof structure in which a synthetic resin layer is provided on an inner or outer surface or an intermediate layer.

The structure of the bottom plate 5 of the box 1 is, for example, each short side plate 3a.
3a, a plate-like structure formed by engaging the ends of the bottom plates 5 which are respectively formed by folding back at the lower portions of the long side plates 3b, 3b, or at the lower portions of the short side plates 3a, 3a as shown in FIG. The triangular bottom pieces 5a, 5a are bent and formed, and one end is cut out at the lower part of each long side plate 3b, 3b in a shape corresponding to the triangular bottom pieces 5a, 5a, and the engaging projection 5b and the engaged concave portion 5c are formed at the top. The formed bottom pieces 5d, 5d are bent and formed,
The other end of each of the bottom pieces 5d is adhered to the triangular bottom pieces 5a and a fold 5 along the oblique side of the triangular bottom pieces 5a.
e, 5e, the box 1 can be folded flat when not in use, and the engagement projections of the bottom pieces 5d, 5d facing each other when the short side plates 3a, 3a and the long side plates 3b, 3b stand up during use. Any one-touch assembly type may be adopted in which the bottom plate is formed by engaging the engagement recess 5c with the engagement recess 5c. Furthermore, the bottom plate structure of the box 1 of the present invention is not limited to the above-mentioned structure, and the box 1 is of a structure that can be folded and has a conventionally known structure that can be formed into a bottomed shape as the box 1 is assembled. Should be fine.

A cover piece 7 provided on the short side plates 3a.
Cuts 11a, 11a for attaching the synthetic resin bag 9 to be provided are formed at both ends of the short sides a, 7a in the vicinity of the short side plates 3a, 3b. The cuts 11a are formed so as to be inclined inward and downward from both ends of the lid pieces 7a as shown in FIG. The cut 11a
a may be either a V-shape as shown in FIG. 4 or an inverted V-shape as shown in FIG.

Then, the synthetic resin bag 9 is mounted in the box 1 as follows.

FIG. 6 is a partially enlarged perspective view showing an attached state of the synthetic resin bag.

Each of the upright short side plates 3a, 3a and the long side plate 3b
Attach the synthetic resin bag 9 along the inner surface of the box 1 to the box 1 in which the respective lid pieces 7a, 7a and 7b, 7b are erected in accordance with 3b. At this time, the upper part of the synthetic resin bag 9 is located on the upper part of each of the side plates 3a, 3a, 3b, 3b. Next, each cut 11 facing the upper part of the synthetic resin bag 9
a. 11a, and hook and fix. At this time, since the cuts 11a are formed so as to be inclined inward and downward, the synthetic resin inserted into the cuts 11a is used to store the contents in the attached synthetic resin bag 9. The upper part of the bag 9 is hard to escape.

In this embodiment, since the synthetic resin bag 9 can be attached without using an adhesive tape or the like, the number of manufacturing steps can be reduced and the manufacturing cost of the box 1 can be reduced. When the synthetic resin bag 9 is unnecessary, the synthetic resin bag 9 can be easily removed. Furthermore, the synthetic resin bag 9 with a low height can be used, and the cost of the box 1 itself can be reduced using the low-cost synthetic resin bag 9.

[0022]

According to the present invention, the manufacturing cost can be reduced. Further, according to the present invention, the synthetic resin bag can be easily removed without damaging the box. Further, the present invention can reduce the manufacturing cost by using a small synthetic resin bag.
