JP3136752U - Bag core structure - Google Patents

Abstract

【Task】
The present invention can be folded into a flat shape when not in use so that it can be easily carried, and at the time of use, it unfolds the flat shape to increase the volume of the bag and collapse the form of the increased volume. The present invention aims to provide a bag that can carry a stored item in a stable state and is less likely to break.
[Solution]
The whole is made of a hard and elastic synthetic resin plate, and the bottom taper part and the rectangular body part are integrated into one body, and the bottom taper part and the body part are foldable and the whole is the same shape as the front core board The back core plate and the triangular corner core plate corresponding to the edge shape of the tapered portion of both core plates are folded, and the corresponding left and right side edges of the main body portion of the front core plate and the back core plate are folded. It is a bag core structure in which a corner core plate is foldably joined to the triangular space edge formed by the tapered portions of both the joined core plates while being freely joined.

Description

  The present invention relates to a bag that can be flattened so as not to be bulky when not in use, and can safely store a large amount of items such as shopping when in use.

The conventional folding bag used for shopping etc. is made of flexible material as a whole, so the bag itself is deformed by weight when used, and the stored items can not be carried stably, There is a risk of damage.

Therefore, the present invention can be folded into a flat shape when not in use so that it is convenient to carry, and at the time of use, it unfolds the flat shape to increase the volume of the bag and increase the volume form. An object of the present invention is to provide a bag that can be kept in a stable state and can be stably transported and is less likely to break.

The whole is made of a hard and elastic synthetic resin plate, and the bottom taper part and the rectangular body part are integrated into one body, and the bottom taper part and the body part are foldable and the whole is the same shape as the front core board Of the front core plate, both front core plates, and the triangular corner core plate corresponding to the edge shape of the tapered portion of the back core plate. The side edges of the bag are foldably joined, and the bag has a core structure in which a corner core plate is foldably joined to the triangular space edge formed by the tapered portions of the joined core plates.

As an effect of the present invention, it can be folded into a flat shape when not in use and is convenient to carry. In this way, the stored items can be transported in a stable state and are less likely to be damaged.

The plan will be described in detail with reference to the illustrated embodiment. The surface core plate 4 is composed of a synthetic resin plate 1 such as a PE plate which is hard and elastic as a whole, and the lower tapered portion 2 and the rectangular main body portion 3 are integrated. The lower taper part 5 and the main body part 6 are sewn via a flexible cloth 7 or the like and can be bent, and the entire back core board 8 has the same shape as the front core board 4, and both the front core board 4 and the back core board 8 Left and right side edges 10 corresponding to each other of the main body portions 3 and 6 of the front core plate 4 and the back core plate 8, respectively. 11 is slightly spaced apart and is joined to the portion by means such as crimping via a flexible cloth 7 and the like, and lower tapered portions 2 and 5 of the joined core plates 4 and 8 are joined together. A corner core plate 9 is foldably joined to the triangular space edge 12 formed by the above.
It is desirable that the core plates 4, 8, 9 are joined to each other by applying a flexible cloth 7 to the joint portions and then bonding them from above.

  When the core plates 4, 8, and 9 are joined to each other, they may be joined to each other, but together with the decorative cloth on the back, front, and bottom (not shown) that covers the core plates 4, 8, and 9. It may be joined or attached. In the figure, reference numeral 13 denotes a bottom cloth.

Claims (1)

  The whole is made of a hard and elastic synthetic resin plate, and the bottom taper part and the rectangular body part are integrated into one body, and the bottom taper part and the body part are foldable and the whole is the same shape as the front core board Of the front core plate, both front core plates, and the triangular corner core plate corresponding to the edge shape of the tapered portion of the back core plate. A bag core structure in which the side edges of the bag are foldably joined, and a corner core plate is foldably joined to the triangular space edge formed by the tapered portions of the joined core plates.
