Description

[Detailed Description of the Invention] The present invention relates to a tube-shaped container for storing creamy products such as toothpaste.

Conventionally, this type of tube-shaped container generally has an outlet portion protruding from one end thereof, and a screw-type cap is screwed onto the outlet portion.

However, with such a type of cap, not only is it troublesome to attach and remove the cap, but
There was an inconvenience that the cap could be accidentally dropped when the cap was removed.

The present invention was developed with the aim of solving the above-mentioned inconveniences, and provides a cap structure for a tube-shaped container that is easy to attach and remove, does not lose the cap, and is inexpensive overall. This is what I am trying to do.

Hereinafter, the structure of the present invention will be explained based on the drawings showing one embodiment. In FIGS. 1 and 2, 1 is an extruded tube-type container body, and one end of this container body 1 has a container for storing therein. An outlet 2 and a cap support piece 3 having a predetermined wall thickness are protruded from opposite sides of the end face in the diametrical direction.

The outer circumferential surface of the outlet 2 is formed in a tapered shape that becomes smaller in diameter toward the tip, and an annular protruding strip 4 is provided at one location on the outer circumference in the circumferential direction.

On the other hand, a support hole 5 is opened in the cap support piece 3.

Reference numeral 6 denotes a cap body having four parts 7 that fit into the outlet 2, and the concave part 7 is fitted into the outlet 2 to close the cap. 8 are connected in series, and at the tip of this continuous piece 8,
A support shaft 9 that projects laterally is integrally formed.

Reference numeral 10 denotes a notch formed in the axial direction from the tip of the support shaft 9, and this notch 10 imparts elasticity to the support shaft 9 in the diametrical direction.

Further, near the tip of this support shaft 9, there is a convex strip 1 in the circumferential direction.
1 is formed.

The diameter of the protruding portion 11 is larger than the support hole 5 of the support piece 3, and the diameter of the other portion is such that it fits into the support hole 5.

The support shaft 9 is fitted into the support hole 5 by utilizing the elasticity in the diametrical direction at the notch 10, and after fitting, the protrusion 11 serves as a stopper for the support shaft 9 to be pulled out. The cap body 6 is rotatable about the support shaft 9, and the outlet 2 is opened and closed thereby.

Reference numeral 12 denotes an annular groove formed on the inner circumference of the recess 7 of the cap body 6 in correspondence with the protrusion 4 on the outer periphery of the outlet 2, and the engagement between the protrusion 4 and the groove 12 prevents accidental damage. Opening of the bottle is prevented.

13 is a knob extending outward from the mouth of the cap body 6, and 14 is a sealing rubber piece inserted into the bottom of the cap body recess 7.

In addition, in the above, the support shaft 9 may be inserted and supported by other methods. For example, after inserting the support shaft 9 into the support hole 5 as shown in FIG. Alternatively, the wedge 15 or the like may be welded into the notch 10 by opening it.

In the above configuration, in order to take out stored items such as toothpaste, the user holds the knob 13 and pulls it up, and the cap body 6 is opened by rotating upward about the support shaft 9, as shown in FIG. Since the cap body 6 moves to the opposite side of the outlet 2, the stored items can be easily pushed out without the cap body 6 getting in the way.

FIG. 4 shows another embodiment of the present invention, in which the end wall surface of the container main body 1 extending from the base of the outlet 2 to the corner on the support piece 3 side is sloped to prevent the extrusion of stored items. In addition to eliminating residual residue, the support piece 3 is set at approximately the same height as the outlet 2 so that the cap body 6 falls toward the container body 1 side. This makes it easier to push out the stored items without causing any problems.

The present invention has the above-mentioned configuration, and in this way, in the present invention, the cap body is always integrated with the container body by the support shaft, so that it will not be accidentally dropped or lost.

On the other hand, since the outer circumferential surface of the outlet part 2 is formed into a tapered shape that becomes smaller in diameter toward the tip, the concave part of the cap body is fitted into the outlet part along this tapered surface, making it extremely easy to attach the cap. be able to.

Furthermore, an annular convex groove is provided in the circumferential direction of the outer circumferential surface of the outlet part, and an annular concave groove that can be freely engaged and detached from the convex groove is also provided on the inner circumferential surface of the concave portion of the cap body, corresponding to the convex line. Since the cap is formed in this manner, the cap can be attached simply by engaging the concave groove with the protrusion, and therefore the cap can be easily removed.

Moreover, since these protrusions and grooves engage each other in an annular manner rather than at a single point, not only is the installation more secure, but
The cap is not easily damaged even after repeated attachment and detachment operations, and has excellent durability.

In addition, the cap body and the support shaft are integrally molded from synthetic resin and are inexpensive, and the support shaft can be easily attached by fitting into the support hole using its elasticity. It is also extremely easy to install.

Furthermore, by protruding the outlet portion of the stored items and the cap support portion to face each other at both ends in the diametrical direction of one end of the container main body,
The opening and closing operations of the cap body around the cap support portion can be easily performed.

In addition, since the cap body can be moved to the side opposite to the outlet, it does not get in the way when taking out the contents, and remarkable effects such as ease of handling can be obtained.
