Description

DETAILED DESCRIPTION OF THE INVENTION This invention is a material that can be applied to plastics such as synthetic resins and aluminum.・Relates to a bag formed of , with foodstuffs etc. sealed inside.

Conventionally, in this insertion, in order to preserve the remaining contents after a portion has been taken out, the opening is wrapped and fastened with another member such as a loop to reseal the opening. However, such a member is not always on hand, and it is troublesome to wrap it around the opening as well as to remove it, and the drawback is that these operations are very short, especially for young children.

Therefore, an object of the present invention is to provide a bag whose opening can be resealed to preserve the contents when necessary, and which is easy to reseal and open.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A bag according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 indicates a mounting body, which is made of a flexible material such as synthetic resin or aluminum. A pair of side sealing bands 2, 2 are formed on both sides of the main body 1 so as to extend along the sides.

A pair of end sealing bands 3.3 are also formed at both ends so as to extend along them. These sealing bands are formed, for example, by sealing and fusing the edges of two sheets constituting the main body 1. The main body 1 is thus sealed by these sealing bands. the side sealing band 2;
A plastic wire 4.4 is attached to 2 so as to extend along the length thereof. By positioning this wire between the sheets, it can be attached to the sealing band during the welding between the sheets. This wire can be formed, for example, by annealing an aluminum wire, and has a wire diameter that allows it to be easily bent by hand. The mounting body 1 has one end sealing band (upper end sealing band) 3.
Nearby and extending along this is the scheduled opening zone 5.
is provided. Both ends of this opening band 5 extend to both side edges of the packaging body 1, that is, to the side sealing bands 2, 2. If the packaging body 1 is made of a material that does not have an easy-to-tear direction, this opening band 5 is provided by pasting a sheet with an easy-to-tear direction on at least one side of the packaging body 1. It can be formed by In this embodiment, it is formed of a synthetic resin tape stretched in the longitudinal direction so that the easy tearing direction is in the longitudinal direction. Instead of such a tape, a pair of tapes 17 may be used which extend parallel to each other at a small distance and which do not have an easy tearing direction. In this case, stress concentration occurs between the tapes so that this portion can easily be torn. Of course, if the main body 1 itself has a direction in which it is easy to tear, there is no need to attach the above-mentioned tape.

In the portion of the scheduled opening band 5 extending to the side sealing band 2,
A notch 6 is formed to extend inward beyond the wire 4. This notch 6 is formed by making a cut line in the side sealing band 2 and also cutting the wire 4 at the -0 mark.

In the bag having the above structure, the bag can be easily opened along the planned opening line 5 by pinching and pulling the area around the notch 6 with fingers. When it is necessary to preserve the contents, the opening can be resealed by bending the portion of the main body 1 near the opening, as shown in FIG. In this case, since the wire 4 is also bent together, the wire 4 undergoes plastic deformation and the bent portion does not return to its original shape. Therefore, the opening of the housing body 1 can be effectively sealed reliably and easily. Furthermore, when resealing this packaging body, it is easy to return the bent part with your fingers.

In other words, such work can be reliably performed over a distance of 1 meter, even by a small child, for example.

In the bags of the above embodiments, the iFj tourniquet is formed by a recessed part made by fusing the sheets together, or by a folded edge formed by folding back a continuous sheet except for the sealing band where the notch is formed. It's also beautiful. Furthermore, the sealing band does not have to be of the same width; for example, it is possible to make the part where the notch is made wider.

In the bag of the fourteenth composition, a combination of a wire rod having plasticity and a notch portion extending in a circular direction from the wire rod (=,
The work of opening, sealing, and resealing the packaging body can be easily and reliably performed without using a separate member such as a rubber band.
