[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 a cap is attached to the container body for filling.
The contents are filled through the opening at the lower end surface of the body, and then the inner surfaces of the lower ends of the body peripheral wall 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 synthetic resin tube container which can be manufactured at a lower cost than the above-mentioned conventional container and is easy to handle.

[0006]

According to the present invention, in order to solve the above-mentioned problems, after filling the contents with the opening at the lower end surface of the container body, the inner surfaces at the lower ends of the body peripheral wall are fused and sealed in a flat plate shape. A tube body made of a synthetic resin, which is a container body 4 having a cylindrical flexible body 2 having an open lower end surface, and a mouth and neck 3 rising from an upper edge of the tube, and a thin wall around the upper edge of the mouth and neck 3 A cut-off rod plug 7 having a rod-shaped base 7a having a lower end peripheral edge connected through a breaking portion 8 to close the upper opening of the mouth and neck, and a grip 7b extending from the upper end of the base 7a; A fitting tube portion 10c which is connected in an inverted state via a flexible connecting rod 9 integrally projecting rearward from the rear end of the upper end of the body 2 and which is detachably fitted to the outer periphery of the container body neck portion 3. Of the top wall 10b and a cap 10 that is suspended from the back surface. Configured.

[0007]

The contents are poured into the container 1 in the state shown in FIG. 1 from the lower end opening of the container body 2, and the lower end inner surface of the body peripheral wall 2b is fused and sealed into a flat plate by a known means, and the contents are sealed. Fill.

When using the contents, the rod stopper 7 is cut off from the broken portion 8 by grasping the grip 7b of the rod stopper 7 and twisting it relative to the container body 2 to remove the container. Body, mouth and neck 3
Open the top. After use, the cap 10 is rotated by 180 ° so that the fitting cylindrical portion 10c is fitted to the outer periphery of the mouth and neck portion 3 and mounted.

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 container 1 is an integrated molded product of a synthetic resin formed by injection molding or the like, and has a container body 4 having a cylindrical mouth and neck 3 erected from the center of the upper end of a cylindrical body 2 having an open lower end surface. Further, the container body 4 has a torso top wall.
The periphery of 2a is recessed downward to form a ring-shaped fitting recess 5, and an engagement ridge 6 is provided around the upper end of the outer periphery of the mouth and neck portion 3. Further, the body peripheral wall 2b is formed to be slightly thin to provide flexibility.

The mouth and neck portion 3 is provided with a bar stopper 7 for closing the upper end opening so as to be cuttable. This stick 7
A cylindrical base 7a having an upper end opening of the container body neck and neck 3 closed by integrally connecting the lower edge to the upper edge of the container body neck and neck 3 via a ring-shaped thin break portion 8; It is formed by extending a flat grip portion 7b extending right and left from the upper end of the base portion 7a. For example, by twisting the grip portion 7b, the breaking portion 8 is broken and the upper end of the mouth and neck portion 3 is opened. doing.

A connecting rod 9 which is formed to be slightly thinner from the rear end of the upper end wall 2b of the container body to provide flexibility and is integrally protruded, and an inverted cap is provided on the rear end of the connecting rod 9. 10 The rear ends are connected together. This cap 10 has a top wall 10b extending from an upper end edge of a peripheral wall 10a for fitting a lower end edge to the fitting recess 5 of the container body 4 and an outer periphery of the container body neck portion 3 from a center of a back surface of the top wall 10b. And a fitting cylindrical portion 10c that fits into the fitting. An engagement ridge 11 that engages with the engagement ridge 6 is provided around the inner peripheral lower end of the fitting cylindrical portion 10c.

In the container 1 constructed as described above, after filling the contents from the lower end opening of the container body 2, the contents are filled by fusing and sealing the lower end inner surface of the body peripheral wall 2b in a flat plate shape. Also, in use, after cutting and removing the rod stopper 7, the body 2 is pressed to pour out the contents from the upper end of the mouth and neck.
10c is fitted to the outer periphery of the mouth and neck 3 and the cap 10 is attached.

[0013]

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, since the whole is formed by integral molding of a synthetic resin, there is an advantage that it can be manufactured at low cost.

Further, since the upper end opening of the mouth and neck portion of the container body is closed by a rod stopper connected through a thin-walled break provided on the upper end periphery, there is no danger of liquid leaking out of the container during filling. In this case, for example, the user can easily open the bag simply by twisting it while holding the holding portion of the plug, which is convenient.
