Description

  In order to divide and store products such as foods into a plurality of parts, the present invention divides each container into a resin container in which a plurality of containers are coupled via a flange portion at the upper edge, and the flange portion for the resin container. The present invention relates to a blade that forms a cut for ease.

  For example, a packaging form of a product such as frozen food is a resin in which a plurality of containers 1 are coupled via a flange portion 2 at the upper edge as shown in FIG. The containers 3 are used and packaged in a state in which the products are stored in the containers 1.

  By the way, in the resin container 3 as described above, a plurality of containers 1 projecting from one sheet-like material to one surface side of the sheet-like material are simultaneously formed by vacuum forming, and each product is taken out after this forming. By performing a process of providing a slit 4 along the length direction for separation at the flange portion 2 between adjacent containers 1 so as to be easily performed one by one, and separating each container 1 from the portion of the cut 4 The product is separated and can be taken out one by one with the container 1.

  Conventionally, the intermittent cut 4 for separating the flange portion 2 of the resin container 3 as described above employs a straight cut, which is usually called a perforation, and is applied along the length direction of the flange portion 2. It has a structure.

  The conventional cutter for providing intermittent linear cuts 4 on the flange portion 2 of the resin container 1 as described above has a structure in which a linear cutting edge is provided intermittently on the side edge of the cutter plate. .

  By the way, since the resin container 3 as described above has a structure in which a plurality of containers 1 are connected via the flange portion 2, the arrangement of the connected containers 1 always maintains a flat form as a whole. However, in order to improve the appearance of the packaging form and the workability at the time of separating the container, this straight line is used in the structure in which the flange portion 2 is provided with the linear cut 4 as in the conventional case. The cut line 4 becomes a crease line between the adjacent containers 1, and as shown by a one-dot chain line in FIG. 6B, the resin container 3 is bent so that the lower part of the adjacent container 1 approaches. When a product is contained inside, there is a problem that the above-described bending is surely generated depending on the weight of the product, and the appearance of the packaging form and the workability at the time of separating the container cannot be improved.

  Therefore, an object of the present invention is to ingenuate the shape of the cut to be applied to the flange portion, to reduce the occurrence of bending such that the lower part of an adjacent container approaches, and to maintain the flat form, the appearance of the packaging form An object of the present invention is to provide a resin container capable of improving and improving workability at the time of container separation, and a blade for making the above-mentioned cut in the flange of the resin container.
