In order to prevent the upper lid from being opened when carrying this kind of container, after closing the upper lid, a pair of holding pieces are locked at both ends of the handle piece, so that the upper lid is in the closed position. Is configured to be retained.

By the way, this kind of container is generally manufactured as follows. That is, a flat plate-shaped material having a predetermined width is prepared and punched into a predetermined shape to obtain a blank. Then, a desired container is assembled and manufactured by bending or joining a predetermined portion of this blank. On the other hand, the material after being punched is disposed of as waste.

[0004]

In the above-mentioned conventional container, the pair of holding pieces are continuously provided on the upper edges of the pair of opposing side walls of the container body. For this reason, when manufacturing this container, the material of the container must be wider than the material used in the container without the holding piece by the length dimension of the pair of holding pieces. However, there is a drawback that the manufacturing cost of the container is high. Furthermore, after punching, there are many parts that must be discarded as dust, which makes it difficult to use the material effectively.

The present invention has been made in view of the above technical background, and an object thereof is a packaging with a handle which can be manufactured by using a material as narrow as possible and can reduce the manufacturing cost. To provide a container.

In this packaging container with a handle, since the holding piece is formed by cutting and raising from a part of the side wall of the container body, the expansion of the container in the width direction in the unfolded state can be suppressed. As a result, the material of the container can be narrower than the material used in the conventional packaging container with a handle, and thus the manufacturing cost of the container can be reduced.

In the container according to the present invention, the means for peelably joining the films is not particularly limited, and various joining means can be adopted. For example, by using a peelable adhesive (including a pressure-sensitive adhesive) or water, applying this to a predetermined portion on the back surface of the film or a predetermined portion on the inner surface of the container and stacking the films, the films are peelably joined. Is listed. Alternatively, if the inner surface of the container or one side or both sides of the film is coated with a thermoplastic resin, or if the container or the film is impregnated with a thermoplastic adhesive containing a thermoplastic resin, etc. You may weakly join so that it can peel. Alternatively, the films may be detachably joined by static electricity.

According to a second aspect of the present invention, in the packaging container with a handle according to the first aspect, the opening formed by the cut-and-raised formation of the holding piece is closed by a film laminated on the inner surface of the container body. It is what

In this packaging container with a handle, it is possible to prevent problems such as dust and dirt from entering the container through the opening.

According to a third aspect of the present invention, in the packaging container with a handle according to the second aspect, the film is laminated in a state of being peelably bonded to at least an inner surface of the container body of the container body and the upper lid. This is to prevent dirt from coming into contact with the object to be packaged.

In this packaging container with a handle, the film can be peeled off from the inner surface of the container after the container has been used, so that the container can be cleaned and recycled. In addition, since this film is laminated in a peelably joined state, there is a problem that the film is torn at the joining portion and part of the film remains on the inner surface of the container while being peeled off from the inner surface of the container. It does not occur, that is, the film can be peeled off neatly.

Further, in this container, when the film is peeled off, a part of the film is peeled off by inserting a finger of the hand into the container through the opening. Then, the peeled portion of the film is picked up to peel off the film.
