Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a synthetic resin container, and more particularly to a synthetic resin container that can be cut and separated into a plurality of containers by hand.
[0002]
[Prior art]
Conventionally, in a synthetic resin container in which a plurality of containers having flanges at the mouth side are integrally formed by pressing, means for manually cutting and separating each container is generally present between the containers. A method of forming a perforation or a half cut portion in the longitudinal direction of the flange portion has been widely used.
[0003]
However, when the perforation is simply formed, it is actually difficult to cut and separate by hand. On the other hand, when the half cut part is formed, vibrations during transportation or moving work are not observed. There has been a problem that it tends to be separated naturally due to impact or the like.
[0004]
[Problems to be solved by the invention]
The present invention has been made in view of the above-described conventional problems, and provides a container made of a synthetic resin that can be easily cut and separated for each container by hand, and that does not easily fall apart during transportation or moving work. The purpose is to do.
[0005]
Thus, as a result of various researches on cutting cuts in order to achieve the object, the present inventor formed non-cut portions having a specific length in the vicinity of both ends of the flange at specific intervals. As a result, it was found that extremely good results were obtained, and the present invention was completed.
[0006]
[Means for Solving the Problems]
That is, according to the present invention, in a synthetic resin container integrally molded in a state where a plurality of containers having flanges on the mouth side are continuously provided, 1 is provided in the longitudinal direction of the flange portion between adjacent containers, in the vicinity of both ends of the flange. It is a synthetic resin container characterized by having a linear slit provided with three uncut parts of ˜2 mm at intervals of 3 to 5 mm.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be further described below with reference to the drawings showing embodiments of the present invention.
[0008]
1 to 3, reference numeral 1 denotes a container body, in which a plurality (three in the present embodiment) of containers 2 are integrally formed by pressing a synthetic resin sheet.
[0009]
Reference numeral 3 denotes a flange portion existing between the containers 2, and the flange portion 3 has linear slits 4a and 5a each having a length of 4.3 mm in order from the outer end edges 31 and 32 of the flange portion, length 1 .2 mm uncut portions 6a and 7a, 4.3 mm long 4b and 5b, 1.2 mm long uncut portions 6b and 7b, 4.3 mm long 4c and 5c in series And a single central line cut 8 is interposed between the innermost line cuts 4c and 5c with non-cut parts 6c and 7c having a length of 1.2 mm. It is configured so as to be formed in series with other linear cuts and non-cuts.
[0010]
Here, the thickness of the flange portion 3 is 0.2 to 0.5 mm, and particularly good results are obtained in terms of ease of separation during use and prevention of separation during transportation. As the shape of the container 2, various shapes such as a triangle, a pentagon, a hexagon, and an oval are used in addition to the quadrangle shown in FIG.
[0011]
【The invention's effect】
In the synthetic resin container according to the present invention, uncut portions are formed in series at specific lengths and intervals in the vicinity of both end edges of the flange portion existing between the containers. While the container can be cut and separated very easily in use, the container is not naturally separated due to vibration or impact during transportation or moving work.
[0012]
Thus, the synthetic resin container of the present invention is particularly suitable as a container for frozen foods for general households to be marketed by filling small amounts (eg, about 80 g) of food such as cooked spaghetti and fried noodles into each container. It is.
