[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tube container for squeezing a body and extruding and discharging contents.

[0002]

2. Description of the Related Art A tube container is a very common daily necessity, and its structure is, of course, not explained. The shoulder and the mouth and neck are provided, and a separate cap is attached to this mouth and neck.They are soft, lightweight, easy to handle and convenient to carry, so not only cosmetics such as cream and toothpaste, but also kneaded It is also widely used for storing seasonings and adhesives.

[0003] Many tube containers of this kind have been proposed in the past, and Japanese Utility Model Application Laid-Open No. 2-73152 is one example.

[0004]

[Problem to be solved by the invention] The problem with this type of tube container is that the ratio of container cost is high,
It was desired to reduce the cost of the container, but a cap was indispensable due to its structure, and there was a limit to the cost reduction because this cap was a separate component.

[0005] The present invention is to obtain a simple tube container which is molded and manufactured in one piece including a cap and which is largely reduced in cost.

[0006]

In the tube container of the present invention, a mouth and neck 3 is erected from an upper end of a thin and flexible tubular body 1 via a thick and rigid shoulder 2 and the mouth and neck 3 are erected. 3 is a cylindrical shape which can be fitted tightly on the mouth and neck part 3 via an extremely thin and breakable joint part 4 from the outer peripheral edge of the top part. A rigid cap 8 extending outward from the side is formed in the shape of a single member standing upright. The cap 8 is closed with a canopy 6 on the top surface, and a top of the cylinder hole is closed with a stopper 5. Then, the connecting portion 4 is broken by this driving so that the fitting portion 4 is detachably fitted to the outer surface of the mouth and neck portion 3, and the lower end opening of the body portion 1 is crushed and closed in a character shape. .

[0007]

As described above, the cap 8 is the canopy 6 with the stopper 5.
As shown in FIG. 1 a, in the form of a cylinder extending outwardly and outwardly, it extends upward from the top of the mouth and neck 3 via a very thin and rupturable joint 4, and as a part with the body side It is formed and formed of a synthetic resin material.

In order to make a container from this molded state,
First, the canopy 6 is closed on the upper surface of the cap 8 as shown in FIG.
With this lid closed, the stopper 5 is inserted into the upper part of the cap cylinder hole, and the top of the cap 8 is closed. Then, the cap 8 is driven downward, and the connecting portion 4 is broken by this driving to fit the outer surface of the mouth and neck portion 3 as shown in each of FIGS.

Thereafter, the contents are filled into the body 1 from the bottom opening with the container in an inverted state, and finally the bottom opening at the lower end of the body 1 is crushed into a single letter and heat sealed.

The driving of the cap 8 may be performed after the contents are filled.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
The present invention is characterized in that it is a simple type in which the body side and the cap are molded and formed as one part, and the cost is reduced.

That is, as shown in FIG. 1A, the tube container of the present invention has the same rigid mouth and neck portion from the upper end of a thin and flexible cylindrical body 1 via a thick and rigid shoulder 2. 3 is erected from the outer peripheral edge of the top portion of the mouth and neck portion 3 having a slightly reduced outer diameter via a joining portion 4 which is extremely thin and can be broken. Ears 9, 9 are protruded, and a rigid cap 8 having a canopy 6 with a plug 5 extending outward from the upper end of the outer edge of the right ear 9 on the right side through a thin hinge 7 is provided upright. It is molded and formed as one part using a synthetic resin material.

The cap 8 has a peripheral groove 10 on the inner peripheral surface of the upper portion of the cylindrical hole, and the outer peripheral surface of the plug 5 has a peripheral groove 11 for engaging with the peripheral groove 10. When the plug is closed, this plugged state is fixed and can be closed tightly, and a single low-profile engaging ridge 12 is formed on the middle and outer surface of the mouth and neck 3, and a flat bottom is formed around the lower end. There is an upwardly facing cap seat 13. The ear 9 on the left side in the figure is raised one step so that the top surface is flush when the canopy 6 is closed.

In order to form a container in this shape, first, as shown in FIG. 1B, the canopy 6 is closed on the top surface of the cap 8, and the stopper 5 is inserted into the upper part of the cylinder hole to close the top. Then, the cap 8 is hit and driven downward, and the connecting portion 4 is broken by this driving and fitted to the outer surface of the mouth and neck portion 3 as shown in each drawing of FIG. The cap 8 is detachable since it is in an independent state at the breakage of the connecting portion 4, and when attached, the lower end surface is joined to the receiving seat 13, and the inner surface is pressed against the ridge 12, so that liquid tightness can be achieved.

Finally, the stored contents are filled from the bottom opening at the lower end of the body 1 in the inverted state, and the bottom opening is crushed into a single character and closed by a heat seal to form the bottom 14.

According to this embodiment, the container including the cap 8 can be formed as one part by molding a synthetic resin material.
The top of the cap 8 can be closed by closing the canopy 6, and the connecting portion 4 is broken by being driven into the outer surface of the cervix 3 so that the cap 8 can be detached and detached, thus providing a normal cap function.

In the above-described embodiment, the shape of the cap 8 is shown in which the ears 9 and 9 are provided from both sides to the outside of the cylindrical body. However, it is sufficient if the cap 8 is cylindrical and the ears 9 and 9 are indispensable. It does not have to be provided.

[0018]

As described above, in the tube container of the present invention, the cap 8 has a cylindrical shape in which the canopy 6 with the stopper 5 is extended outward from the upper side through the thin hinge 7 to the mouth and neck. Part 3
From the top, a synthetic resin material is formed integrally with the body side in a shape standing upright via a breakable joint 4, and after molding, the canopy 6 is inserted into the upper part of the cylinder hole with the lid 6 closed. Cap 8
Since the top is closed and the cap 8 is driven downward, the connecting portion 4 is broken by this driving so as to be removably fitted to the mouth and neck 3 so that the cap is made as a separate member as in the conventional case. The cost can be greatly reduced as compared with the case.
