Description

[Detailed Description of the Invention] The present invention relates to a body frame for a container of both types, which is composed of a body frame and a bottom plate, which are commonly used.

That is, it is a container frame in which a transverse wall having a partitioning function is integrated with the frame.

In conventional containers with partitions, the partitions are manually attached to the inner side of the rectangular body frame, and then the bottom plate is attached to assemble both types of containers.

The method is to attach the partition to the inner side of the fuselage frame with a needle (see Figure 1), or to provide a pair of concave grooves on the inside of the fuselage frame and insert and fix the inner partition after Narita into the groove. there were.

However, all of these methods have the following drawbacks.

That is, in the method of fixing with a needle, the needle cut out of the metal is exposed on the side of the barrel frame, resulting in an unsightly appearance.

Furthermore, the method of inserting the partition into the concave groove requires processing in advance to provide a pair of concave grooves on the inner side surface of the barrel frame.

Furthermore, since these operations are performed manually, they must be performed hygienically.

An object of the present invention is to provide a separate frame for a lunch box that is inexpensive, hygienic, and easy to assemble.

This object is achieved by providing a cross wall having a partitioning function inside the barrel frame when the barrel frame is manufactured by a drawing process.

In other words, if the trunk frame is made flat and raised into a square shape,
Since the partition is formed inside the rectangular body frame, manual work for attaching the partition is eliminated, and a rectangular body frame with a partition can be obtained at low cost and in a sanitary manner.

This double-sided bento box, which has a bottom plate attached to the body frame, requires a shorter assembly process compared to conventional double-sided bento boxes.

Streamlined.

Next, the present invention will be explained in detail with reference to examples.

A board having a size necessary to make a plurality of body frames and having a thickness of 1 mm and a wood grain pattern printed on the surface is punched out and at the same time six ruled lines are added.

(Refer to Figure 1 for punching configuration) The punching conditions are: 2 mm in the crease blade, press pod height l,
Qmm, width 4mm, and it was made using a flat plate punching machine. Therefore, the paperboard was marked with 6 ruled lines numbered 8 to 13 on the glued piece 1, the middle partition 2, and the side walls 3, 4, 5, 6.7. Separated.

Next, this material A is run through a box-forming machine to form a trunk frame having a transverse wall with a partitioning function.

First, glue is applied to the side wall 7, and the glued piece 1 is attached to the side wall 5 while bending the ruled line 10.

Next, glue is applied to a part of the side wall 7, and the side wall 7 is attached to the inside of the side wall 3 while bending the ruled line 12.

If you raise the trunk frame into a rectangular shape from the flat state of the box, it will have the shape shown in Figure 2.

In the box-making process, it is possible to make boxes without causing cracks or poor adhesion of the paperboard, and vinyl acetate emulsion type glue is used as the glue.

Next, the finished boxed product is cut into a container frame width of 3Qm using a flat plate punching machine.
Punch out to m.

In this case, the cutting die was used to cut out three sheets of paperboard, so the cutting edge of the cutting blade was 8 mm, and a relatively hard sponge with a height of 12 mm was used to prevent the punched product from getting stuck between the cutting blade edges. It is best to paste it on the surface of the mold.

In this way, creating a large number of body frames by punching in one go with a flat plate punching machine is faster and the cutting width is more accurate than when using a cutting machine (guillotine cutter). It has the advantage of not producing paper dust on the cut end.

In addition, if a small joint is left on the cut body frame during punching, this joint will prevent the body frame from falling apart, making it easier to perform tasks such as packing the product into boxes for inspection and attaching the bottom plate.

In order to leave a seam during punching, a recess is provided on the cutting edge of the cutting die, and this recess leaves a seam.

When using paperboard with a thickness greater than 1.1 mm, if the ruled lines 10, 12 L are not bent and cannot be folded (into a rectangular shape) after making the box, the ruled lines 8°9.11 ．．
This can be solved by bending each of the 12 pieces before forming the box.

FIG. 3 shows the form in which the cut frame is raised up and used as a container frame.

In the above-mentioned embodiment, the ruled lines 8 are folded in reverse, and as the paper becomes thicker, there is a risk of cracking.

For this reason, the drawing process becomes a little complicated, but it is also possible to bend the ruled line 8 in the forward folding direction and adhere the back surface of the glued piece 1 to the side wall 5.

(See FIG. 4) Furthermore, in order to carry out the invention advantageously, it is also possible to reduce the overlapping portion of the side walls 3, 7, thereby saving the amount of paperboard used.

(See Figure 5) The body frame of the present invention has a shape in which the side walls 3 and 7 overlap, but the side wall 7 in the portion that overlaps with the side wall 3 is bent inward and formed so that it overlaps with the partition 2 back to back. You can also do that.

Since the present invention has the above-mentioned structure, it is possible to easily and simultaneously create multiple body frames from a single piece of material, and since it is made from a single piece of material, the structure is extremely simple. In addition, the inner wall surface of the body frame has the same inner surface, and the material used is only one side, so it is possible to select a material that has characteristics suitable for the goods to be stored, and is suitable for use as a body frame for lunch boxes, etc., for example. It is.
