[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tube container made of synthetic resin.

[0002]

[Prior art]

SUMMARY OF THE INVENTION As a tube container made of a synthetic resin, a container body having a cylindrical shape with an opening at the lower end face and having a mouth and neck standing upright from the upper end of a flexible body, There is known a cap which is detachably fitted to a neck to close an upper opening of the mouth and neck.

In these methods, a container body and a cap are separately formed, and when filling the contents, the cap is attached to the container body, and then the contents are filled through an opening at the lower end face of the body, and then the peripheral wall of the body is filled. The inner surfaces of the lower ends are fused and sealed in a flat plate shape.

[0004] Therefore, the capping process is required for the filling operation, and a mold for forming the container and the cap is required.

The present invention proposes a tube container made of synthetic resin which can be manufactured at a lower cost than the above-mentioned conventional container and is easy to handle.

[0006]

In order to solve the above-mentioned problems, the container of the present invention injects the contents from the opening at the lower end face of the body of the container body, and then fuses and seals the inner surfaces of the lower end of the body peripheral wall into a flat plate shape. A tube body made of a synthetic resin to be formed, the container body 2 having a cylindrical mouth and neck portion 6 standing upright from an upper end of a cylindrical flexible body portion 5 having an open lower end surface; And a lid plate 3 large enough to integrally and rotatably connect the back surface of the rear end portion via a hinge portion 7 and to close the upper end opening of the container body neck 6. In the rotationally inclined state of FIG. 3, a deformed peripheral wall 4 extending from the peripheral edge of the back surface of the lid plate to the inner peripheral upper end of the mouth and neck and forming a circular rotation trajectory is integrally provided to close the upper end opening of the mouth and neck. A thin break portion 8 is provided at the lower edge of the modified peripheral wall 4 other than the plate hinge portion 7.

[0007]

After the contents are poured into the container 1 in the state of FIG. 1 from the lower end opening of the container body 5, the inner surface of the lower end of the peripheral wall of the body is fused and sealed in a flat plate shape by a known means to fill the contents. I do.

In using the contents, the thin break 8 is cut off, and the upper end of the mouth and neck 6 of the container is opened. Next, the body 5 is squeezed to discharge the contents in the body 5 from the upper end of the mouth and neck 6. After use, as shown in FIG.
Is accommodated in the mouth and neck 6 and the container body and neck 6
Close the top opening.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 show an embodiment of the present invention, in which 1 indicates a tube container made of synthetic resin. The container 1 is an integrally molded product of a synthetic resin and includes a container body 2, a cover plate 3, and a modified peripheral wall 4.

The container body 2 has a cylindrical mouth and neck 6 standing upright from the center of the upper end of a cylindrical body 5 having an open lower end.
Further, the body peripheral wall 5a is formed to be slightly thin to provide flexibility.

The lid plate 3 has a disk shape having a size capable of closing the upper end opening of the container body neck 6, and has a hinge 7 on the rear end rear surface at the upper surface rear end of the container body neck 6. They are integrally and rotatably connected to each other.

Further, the deformed peripheral wall 4 has a rotation locus shape of a circle extending from the peripheral edge of the back surface of the lid plate 3 to the upper peripheral edge of the inner periphery of the container body neck 6 in the rotationally inclined state of the lid plate 3. That is, a curved wall having an outer peripheral surface having a locus shape formed when the circular shape of the upper end opening of the container body neck 6 is turned upward around the hinge portion 7 with the lid plate 3 at the rear end thereof, The peripheral wall 4 closes the upper end opening of the container body neck 6 in a liquid-tight manner. A portion other than the hinge portion 7 of the cover plate is formed thin at the lower end edge of the irregularly shaped peripheral wall 4 to constitute a break portion 8 that is broken by pulling the cover plate 3 in the opening direction. Further, a ridge 9 parallel to the lid plate is protruded above the front surface of the outer surface of the deformed peripheral wall 4, and when the rupture portion 8 is cut and the lid plate 3 is closed, the upper end of the inner peripheral portion of the mouth-neck portion 6 is formed. The cover 3 is configured to be in contact with it to prevent the cover plate 3 from being inadvertently opened when not in use. In addition, a vertically long rectangular plate-shaped gripping portion 10 is protruded upward from the front end of the lid plate 3.

It is preferable that the cover plate is rotated at an inclined angle such that the cover opening angle is an acute angle, which is smaller than about 60 °.

[0014]

As described above, the container of the present invention has the above-described structure, so that the cap mounting step can be omitted when filling the contents, and the filling operation can be performed efficiently. Further, the whole is formed by integral molding of synthetic resin, and the structure is relatively simple, so that it can be manufactured at low cost.

Further, since the upper end opening of the mouth and neck of the container body is closed in a liquid-tight manner by a deformed peripheral wall connected through a thin break portion provided at the upper end periphery, the contents are opened from the upper end opening of the mouth and neck at the time of filling. There is no danger of leakage, and in use, it can be easily opened simply by pulling on the lid plate, which is convenient.
