The lid 3 has a fitting cylindrical portion 8 on the outer periphery of the mouth / neck portion 6.
The upper end of the mouth and neck is closed by the top wall thereof. In the present embodiment, the fitting cylinder portion 8 screwed to the outer circumference of the mouth and neck portion 6 is attached to the top wall 9. It is constructed by vertically arranging it from the center of the lower surface and vertically arranging a peripheral wall 10 from the outer periphery of the top wall 9.

Further, the sealing cylinder 4 is erected on the upper surface of the container body 5 through the breaking portion 11 so as to be cuttable, and surrounds the outer periphery of the lid body 3 so that the lid body 3 cannot be removed. is doing.

In this embodiment, the sealing cylinder 4 is the lid 3 described above.
The peripheral wall 10 has a cylindrical shape having an inner circumference slightly larger than the outer circumference, and the lower end edge is broken at the outer peripheral edge of the top wall of the top wall of the body of the container.
It is integrally connected via 11.

The breaking portion 11 includes the inner surface of the lower end of the sealing cylinder 4 and the top plate portion.
5b upper surface and a plurality of circumferentially provided thin triangular plate-shaped connecting pieces 11
It is configured by being integrally connected by a. Further, the height of the sealing tube 4 is preferably configured to be the same as or slightly higher than the upper surface of the fitted lid body 3, and if the height is much lower than the upper surface of the lid body 3, the lid body 3 can be easily unscrewed. This is contrary to the purpose of the present invention.

The sealing cylinder 4 and the container body 2 are integrally formed by a method such as injection molding, and the separately formed lid body 3 is opened by using a capper (of a type in which the top surface of the lid member is pressed and rotated). It can be formed by fitting the outer circumference of the neck 6.

The container thus constructed is filled with the contents from the lower end opening of the container body 5, and then the lower end of the body is used in a conventional container of this kind such as heat sealing. The product is closed in a flat shape by the method described below.

FIG. 3 shows another embodiment of the present invention.
In this embodiment, instead of the screw thread provided around the outer circumference of the container neck 6 in the above embodiment, the protrusion 12 is provided at a predetermined position, and the inner circumference of the fitting cylinder portion 8 of the lid 3 is also changed. The protrusion 13 is provided at a predetermined position in place of the screw provided around the above, and the lid 3 is pushed down from above to be fitted. The ridges 13 are configured so that they can be passed over and engaged. The other configurations are similar to those of the above-described embodiment, and therefore, the same reference numerals are given.

FIG. 4 shows still another embodiment of the present invention, which is an example of a container in which the lid body 3A is attached to the container body via the cap body 18 so as to be openable and closable.

In the present embodiment, the fitting cylinder portion 14 screwed onto the outer periphery of the mouth / neck portion 6 is vertically provided from the central portion of the rear surface of the lid plate 15, and
A peripheral wall 16 is hung from the peripheral portion of the cover plate 15, and a spout hole 17 is formed in the central portion of the cover plate 15 so as to communicate with the upper end opening of the mouth and neck 6, and a peripheral wall is formed at the upper end of the rear portion of the main body. 19 The lower end of the rear part is rotatably connected, and the upper surface of the cap body is integrally formed with a lid 3A provided so as to be openable and closable. In the figure, 20 indicates a packing.

[0021]

As described above, in the container of the present invention, the contents cannot be poured out unless the envelope is removed, and the envelope does not return to its original state once it is cut. As long as it exists, the unused state of the container can be determined at a glance.

Further, since the container body and the sealing cylinder can be formed as an integrally molded product of synthetic resin and other lid body (or lid body with a cap body) is sufficient, the structure is simple and the manufacturing is easy.

Further, since the sealing tube has its lower end edge integrally connected to the container body through the ruptured portion, for example, if the sealing tube is twisted while holding the body of the container body, the ruptured portion is easily cut. It is extremely easy to open.

The attachment of the lid and the filling of the contents can be performed by a conventional method, and no special device is required.
