Abstract

PROBLEM TO BE SOLVED: To provide a sealed container made of a resin, which can be easily unsealed without applying a large force when being initially unsealed, but which is hard to accidientally open. SOLUTION: This sealed container made of a resin is equipped with a body section and a lid section. In this case, the top of the body section is open, and at the upper end of the body section, an internal annular section and an external annular section are formed. The lid section closes the upper open section of the body section, and a lid annular section which is fitted in a space between the internal annular section and the external annular section is formed on the lid section. Also, the external annular section is formed to be easy to separate from the body section. In such a sealed container made of a resin, a stress concentrating means is provided on the external annular section so that the external annular section may become easy to shear.

SUMMARY OF THE INVENTION In any of the above containers,
The first opening is made possible by cutting off a part of the lid or body, such as the outer ring or the brand new band. Further, by separating a part of the container, it can be recognized whether or not the container has been opened once. Therefore, when it is desired to open the outer ring, it is desirable that the outer annular portion and the like can be easily cut off without applying a strong force. On the other hand, when the opening is not intended, the outer annular portion or the like must not be accidentally cut off. The conventional container as described above is provided with a knob or a projection for separating the outer annular portion or the like in order to facilitate opening. However, since the outer annular portion and the like are formed integrally with the lid or the body of the container with appropriate strength so as not to be accidentally cut off, they cannot be easily opened even if the knob or the like is pulled. There is a problem.

The resin-made sealed container according to the present invention is used as follows. The contents are filled in the accommodating part 18 of the body part 10,
Next, the lid portion 40 is placed on the body portion 10 and pressed to fit the lid portion 46 of the lid portion 40 between the outer annular portion 22 and the inner annular portion 20 of the body portion 10. . At this time, the inner annular portion 20 and the outer annular portion 22 of the soft plastic body 10 extend, and the thick portion 48 of the lid annular portion 46 extends.
However, the seal is formed over the retaining protrusion 34 of the outer annular portion 22 and the sealing protrusion 26 of the inner annular portion 20.

At the time of opening, the outer annular portion 22 connected in a ring shape is sheared in the vicinity of the finger hook protrusion by pulling the finger hook protrusion 32. Next, the finger hook projection 32 is further pulled to cut the thin portion 30, thereby separating the outer annular portion 22 from the outer projection 24. At this time, since the outer annular portion 22 is provided with the stress concentration means 35 adjacent to the finger hook projecting portion, the stress generated in the outer annular portion 22 by pulling the finger hook projecting portion 32 causes the stress concentration. Since it concentrates on the means 35, the outer annular portion 22 can be easily sheared even with a small tensile force. That is, due to the stress concentration effect provided by the stress concentration means 35, the force pulling the finger hook projection 32 effectively shears the outer annular portion 22.

Further, in the container according to the present invention, since the outer annular portion 22 can be effectively sheared with a small force as described above, the outer annular portion 22 is made thicker than when the stress concentration means 35 is not provided. Even if designed, the outer annular portion 22 can be sheared by hand. Thereby, the finger hook protrusion 3
Without pulling 2, the outer annular portion 22 is less likely to be accidentally cut off.

Moreover, in an advantageous configuration of the invention, the stress concentration means 35, ie the grooves, are at an angle which is not orthogonal to the outer annular part 22,
That is, since the outer annular portion 22 is provided at an inclined angle with respect to the outer annular portion 22, the outer annular portion 22 can be more efficiently sheared. That is, when the finger hook protrusion 32 is pulled directly upward to shear a groove provided at a right angle to the outer annular portion 22, most of the pulling force applied to the finger hook protrusion 32 is reduced by the outside. It acts as a force to bend the annular portion 22 outward, and less component force acts to shear the outer annular portion 22. On the other hand, when the groove is provided at an inclined angle and the finger hook protrusion 35 is pulled in the direction of the groove, more of the applied pulling force is applied to the outer annular portion 22.
Acts as a component force for shearing. By this action, the outer annular portion 22 can be more efficiently sheared. After the outer annular portion 22 is cut off and opened, the body 10 and the lid 40 can be used as a sealed container that can be repeatedly opened and sealed.

That is, the inner annular portion and the outer annular portion integrally formed so as to be easily detachable are provided on the lid portion, and the inner annular portion and the outer annular portion corresponding to the lid annular portion of the embodiment are provided on the body. An annular portion may be provided between the outer annular portion and a stress concentration means and a finger-hook protrusion may be provided on the outer annular portion.
