However, when the packaging operation is performed by a series of mechanical operations using an automatic machine or the like, in the conventional packaging container, the deformation reaction force of the curved ridge 27 when the lid portion 25 is folded back is relatively large. Therefore, against the deformation reaction force,
The force required for fitting the lid portion 25 to the container main body portion 22 and inducing the mutual engagement of the male and female engaging portions 28a and 28b is inevitably large. However, if the external force for closing the lid of an automatic machine or the like is too large, it becomes large. There is a high possibility that the packaging container made of a soft plastic material will be deformed or damaged, and may even crush the object to be packaged.

SUMMARY OF THE INVENTION The present invention relates to a packaging container having a lid made of, for example, polystyrene or the like, which has a thickness of 0.025 in a streak-like thin portion provided at a connecting portion having a thickness of 0.35 mm.
By reducing the thickness to the range of ~ 0.1 mm, the required external force to fold back can be sufficiently reduced when the lid is folded over the container body around the streak-like thin portion, and the lid once folded back Even if the lid is not completely fitted to the container body, the lid is made based on the finding that the lid can be sufficiently maintained in its closed position. The packaging container with a container includes a container body portion, a lid portion that fits into the container body portion, and a connecting portion that integrally connects the two portions, and a substantially central portion in the width direction of the connecting portion. A linearly extending strip-shaped thin portion is provided over the entire length of the connecting portion, and a streak having the same or somewhat thinner thickness as the continuous portion is provided at an end or an intermediate portion of the strip-shaped thin portion. Fewer thin-walled parts Both is provided with a one discontinuity.

In the packaging container with a lid according to the present invention, the thickness of the lid is reduced to a required thickness according to the material and the like by the streak thin portion provided in the connecting portion, so that the streak thin portion is formed. As a field, it can be smoothly folded over the container body with a sufficiently small force.
Since the plastic deformation is generated by the action of such a folding external force, the restoring force of the streak-like thin portion once folded back to the open position is extremely small. Even if it is impossible to sufficiently fit the outer peripheral surface of the upper end portion or the like, it is possible to reliably prevent accidental opening of the lid portion thereafter.

[0014] This is more effective as the thickness of the streak-like thin portion is made thinner. However, if the thickness is made too thin, the lid portion is folded back so that the lid portion and the container main body portion are connected to each other. When the connecting portion is very likely to break from the position of the streak-like thin portion, and when the breaking causes the lid portion and the container body portion to be completely separated from each other, it is assumed that both of them are connected. The packaging work in the packaging device may be hindered, and even if the packaging work is possible, when handling the container after packaging In addition to impairing the feel of the container, during the display of the container in a state in which the packaged product is packaged, the break-separation portion causes the container and, in turn, the appearance of the packaged product to deteriorate, and dust and the like from there. Invasion of In addition, there is a problem that the consumer of the packaged product may raise doubts about the quality of the packaged product due to the lid portion falling off from the container body portion simultaneously with opening the container. .

Therefore, in the container according to the present invention, as a result of pursuing the ease of folding of the lid portion and the prevention of the opening displacement of the once folded lid portion, even if a part of the streak-like thin portion is broken, However, by effectively preventing the propagation of the rupture, and by sufficiently preventing the lid portion from being separated from the container body portion, a streak shape is formed to effectively remove the room where the above-described problem occurs. At least one break in the thin portion is provided at an end or an intermediate portion of the thin portion. Here, the length of each break is, for example, 0.5 to 5
mm.

Here, in the case where a plurality of streak-like thin portions having discontinuous portions are formed in the connecting portion in parallel with each other,
The folding mode of the lid portion can be selected as required. According to this, since the bending angle at each streak thin portion can be effectively reduced, the thickness of the streak thin portion is made sufficiently thin. In addition, it is possible to effectively prevent cracks, breaks, and the like from occurring in the thin streaks.

The streak-like thin portion provided with the discontinuity can be formed from at least one of the upper surface and the lower surface of the connecting portion of the container in the open position. Forming can be performed by pressing the required intermittent ridges provided on at least one of the upper mold and the lower mold of the container molding die against the connecting portion during molding of the container. It can also be performed by pressing a hot blade or an ultrasonic welder to a required position of the connecting portion in an open state or a state in which the molded product is removed from the mold.

Here, from the lower surface side of the connecting portion, for example,
The streak-shaped thin portion melt-formed by pressing the ultrasonic welder is mainly subjected to compressive deformation in its cross section when the lid is folded back, so even if the thickness of the streak-thin portion becomes too thin, The risk of breakage at the position of the thin portion can be reduced. On the other hand, the streak-like thin portion formed from the upper surface side undergoes a large tensile deformation in its cross section, so that the thickness of the thin portion is somewhat thicker. However, sufficient plastic deformation can be caused there.

Further, the streak-like thin portion is formed not only in a connecting portion having a flat shape as a whole, but also in a curved ridge provided at a central portion in the width direction of the connecting portion and protruding downward. According to the former, it is possible to bring about direct plastic deformation of the streak-like thin portion, and according to the latter, it is possible to bring about plastic deformation thereof through elastic deformation of the curved ridge.
