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 synthetic resin, a container body having a cylindrical body with a lower end face opening and having a mouth and neck standing upright is detachably fitted to the mouth and neck. And a cap for closing the upper opening of the mouth and neck.

In filling the contents, for example, the upper end of the mouth and neck is closed with an aluminum sheet or the like, a cap is attached to the mouth and neck, and then the contents are injected through the opening of the lower end of the body of the container. However, since the lower inner surface of the body peripheral wall is fused and sealed in a flat plate shape, the filling operation is troublesome, and if the mounting of the aluminum sheet is omitted, the liquid may leak from the mouth and neck at the time of filling. Occurs.

The present invention proposes a synthetic resin tube container which can be manufactured at a lower cost as compared with the above-mentioned conventional container of this kind and which can perform the filling operation efficiently.

[0005]

In order to solve the above-mentioned problems, the container of the present invention fills the contents from the opening at the lower end surface of the container body and then fuses and seals the inner surfaces of the lower ends of the body peripheral wall into a flat plate shape. A tube container made of synthetic resin, comprising a container body 2 and a cut-off plug 3 provided so as to be capable of cutting and closing the pouring hole 5 of the container body 2 by integral molding of synthetic resin. The body 2 is formed by piercing a pouring hole 5 at the center of an upper end of a cylindrical flexible body 4 having an open lower end surface, and the cutoff plug 3 is provided with a thin break portion around the upper end of the pouring hole 5. A bar-shaped base 7 having its lower peripheral edge integrally connected via a base 6 and a laterally protruding side from the upper end of the side of the base 7 via a thin hinge 8, and is fitted in a liquid-tight manner from the lower surface into the above-mentioned pouring hole 5. And a rotatable base plate 10 having a vertically protruding rod stopper 9 at the top surface of the container body top wall 4b. A rod-shaped projection 11 is protruded at a fixed position, and a fitting recess 12 which is rotatably fitted to the projection 11 is formed in the center of the lower surface of the rod-shaped base 7. The cut-off plug 3 is fitted to the rod-shaped projection 11. The bar plug 9 was configured to be able to fit into the pouring hole 5 when combined.

[0006]

After the contents are injected from the lower end opening of the container body 4 from the state shown in FIG. 1, the inner surface of the lower end of the body peripheral wall 4a is fused and sealed in a flat plate shape by a known means to fill the contents.

In using the contents, FIG. 2 (a)
Then, the plug 3 is cut at the broken portion 6 to open the upper end of the pouring hole 5, and then the body 4 is squeezed to pour the contents in the body 4 from the upper end of the pouring hole 5. Put out.

At this time, the removed plug 3 is
The fitting recess 12 is rotatably fitted and mounted on the rod-shaped projection 11 on the upper surface of the top wall of the container body. After use, the rod stopper 9 can be opened in a liquid-tight manner as shown in FIG. The opening of the upper end of the pouring hole 5 is sealed by fitting.

For re-use, the pivot plate 10 is pivoted upward to remove the rod plug 9, and then the pivot base 10 is pivoted horizontally as shown in FIG. Does not hinder the dispensing of the contents.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show an embodiment of the present invention. In the drawings, reference numeral 1 denotes a synthetic resin tube container. The entire container 1 is formed as an integral molded product of a synthetic resin, and includes a container body 2 and a cutoff plug 3.

The container body 2 has a body portion 4 in which a conical plate-shaped body top wall 4b is extended from an upper end edge of a cylindrical body peripheral wall 4a having a lower end surface opened. An injection hole 5 is formed at the center of 4b. Further, the body peripheral wall 4a is formed to be slightly thin to give flexibility to the body 4.

The cut-off plug 3 has a cylindrical rod-like shape that seals the opening at the upper end of the pouring hole 5 by integrally connecting the peripheral edge of the lower surface of the container 2 to the upper end of the pouring hole via a thin-walled break portion 6. It comprises a base 7, and a turn board 10, which is provided at the upper end of the side surface of the base 7 via a thin hinge 8 so as to be rotatable in the vertical direction, and has a cylindrical rod plug 9 suspended from the lower surface.
The rod stopper 9 is configured so as to be able to fit into the pouring hole 5 in a liquid-tight manner.

At a predetermined position on the upper surface of the body top wall 4b of the container body 2, a flat surface is formed which is recessed in a plane arc shape, and a columnar rod-like projection 11 is projected from the upper surface of the flat surface. I have. Further, in the center of the lower surface of the rod-shaped base 7 of the cutoff plug 3, a fitting concave portion 12 which is rotatably fitted to the projection 11 is formed. After the cut-off plug 3 is cut and removed from the thin-walled break portion 6, when the fitting recess 12 is rotatably fitted to the rod-shaped projection 11, the pouring hole opened by the rod stopper 9 is provided. 5
It is configured to fit in a liquid-tight manner.

[0015]

[Effects of the Invention] As described above, the container of the present invention has the above-described structure, so that the step of mounting an aluminum seal or the like can be omitted when filling the contents, and the filling operation can be performed efficiently. Further, since it is formed by integral molding of a synthetic resin and has a simple structure, there is an advantage that it can be manufactured at low cost.

Further, since the spouting hole of the container is closed by a cut-off plug connected via a thin-walled break provided at the upper peripheral edge of the container, there is no danger of liquid leaking out of the container during filling. In this case, for example, the container can be easily opened simply by inclining the cutoff stopper with respect to the container body, and the device is easy to use. In addition, when discharging the contents,
After turning the plate upward and removing the plug, the bar
Can be rotated in any direction.
Even if you do not hold it, it will not disturb the dispensing.
