Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a device for closing the mouth of a container containing liquids, powders, etc.

[Conventional technology]

Conventionally, a container mouth closing device equipped with a mechanism for disengaging the container from the cap is described in Japanese Utility Model Application Publication No. 59-3850.

The container mouth closing device described in the above publication is
As shown in FIG. 5, in the pouring tube 2 of the container body 1,
The inner cylinder 27 provided on the cap 15 is removably fitted, the opening of the spouting cylinder 2 is closed with the cap 15, and the outer cylinder 3 provided on the cap 15 is closed.
0 to the slanted shoulder 2 of the container body 1.
5.

5, when the lower end of the outer cylinder 30 is pressed from both sides, the outer cylinder 30 closes.
The lower end edge of the container body 1 is pushed upward by the inclined shoulder 25 of the container body 1, and the cap 15 that has been engaged with the dispensing tube 2 is disengaged.

[The problem that the idea aims to solve]

The closure device for the container opening shown in FIG. 5 is convenient because the cap 15 can be disengaged from the dispensing barrel 2 by pressing the lower end of the outer barrel 30 of the cap 15.

However, the cap 15 is
If the outer cylinder 3 is not formed thickly and has great rigidity,
0 is curved and bent so as to bulge outward at the center, and the upper part of the outer cylinder 30 is not pushed upward.

If the outer cylinder 30 is made thick and rigid, a large force will be required to press the lower end of the outer cylinder 30.

The present invention has been made in view of the above-mentioned matters, and is a container mouth closing device formed to press the outside of the cap and push up the cap by the action of an inclined surface to disengage the cap.
A technical problem is to make it possible to reliably push up a cap and release the engagement with a small pressing force.

[Means to solve the problem]

In the present invention, a pouring tube 2 is provided in a container body 1, a pouring tube section 5 having a pouring spout 8 is fitted into the pouring tube 2, and the pouring tube section 5 has elasticity. A cap 15 made of a material is fitted, and a closure member formed as a stopper 11 or an outer fitting tube 13 provided on the cap 15 is removably fitted into the spout 8, and both sides of the cap 15 are fitted. at least one of the lower ends of the cap 15 is provided so as to be in contact with the shoulder of the spouting cylinder 5, and at least the lower end of the side of the cap 15 that comes into contact with the shoulder of the spouting cylinder 5 is connected to the shoulder of the spouting cylinder 5. One side is the inclined surface 16 (16A in the figure,
16B), and the other is formed into a protrusion 6 (indicated as 6A and 6B in the figure).
Further, the inclined surface 16 was formed to be inclined with respect to the center line of the spouting cylinder part 5 so as to spread downward, thereby forming a closing device for the container mouth part.

[Effect]

To remove the cap 15 of the present invention, remove the spout tube 5.
The side part of the cap 15 fitted into the spouting cylinder part 5
Press against the shoulder of the person.

Then, the inclined surface 1 formed on either the lower end of the side of the cap 15 or the shoulder of the spouting cylinder 5
6, 16A or 16B is in contact with the shoulder of the other spouting cylinder 5 and the protrusion 6, 6A or 6B formed on the side of the cap 15, when the side of the cap 15 It moves toward the center of the spouting cylinder part 5.

Then, the side portion of the cap 15 is pushed upward by the inclined surface 16, 16A or 16B, and the closing member of the cap 15 (the closing member formed as the plug 11 or the outer fitting cylinder 13) is closed. It comes out of the spout 8 of the outlet tube part 5, and the closing member is released from the tightly and tightly fitted state.

Then, when the cap 15 is pinched and pulled upward, the cap 15 is separated from the spouting cylinder part 5, and the spout 8 of the spouting cylinder part 5 is opened.

[Embodiment] Figures 1 to 3 show an embodiment of the present invention, in which a container body 1 is provided with a spouting tube 2, and the spouting tube 2 has a protrusion for fitting. 3 is provided. The spout tube part 5 fitted into the spout tube 2 is provided with a fitting groove 10 and an inner tube 9, and is also provided with a spout tube 7 to form a spout 8. There is. Further, a protruding portion 6A is formed on the shoulder of the spouting cylinder portion 5, with which an inclined surface 16A to be described later comes into contact.

Note that the portion of the protruding portion 6A that contacts the inclined surface 16A may be formed into an inclined surface.

A cap 15 made of an elastic material is fitted onto the spouting cylinder 5.

A cylindrical protrusion 17 that protrudes downward is provided on the lower surface of the top of the cap 15, and a closing member including a plug 11 and an outer fitting cylinder 13 is fitted into this protrusion 17. ing. The fitting is performed by fitting a cylindrical portion projecting upward from the closing member onto the protruding portion 17. Furthermore, the plug 11 has a projection 1 for fitting.
2 is provided.

Further, a concave groove 14 is provided inside the cylindrical portion that protrudes upwardly of the closing member including the plug 11 and the outer fitting tube 13, and a protrusion provided on the cap 15 is provided in the concave groove 14. A tip protrusion 17 is fitted to fix the closure member to the cap 15.

The closure member may be a lid having only the outer tube 13 that is fitted into the spout tube 7 by removing the stopper 11.

The lower ends of both sides of the cap 15 are provided with inclined surfaces 16A that abut the protruding portions 6A, and the inclined surfaces 16A extend downwardly with respect to the center line of the spouting cylinder portion 5. It is sloping. It is preferable that the inclined surfaces 16A are provided oppositely on both sides of the cap 15, but if the fitting portion of the plug 11 or the like is short, it may be provided only on one side.

FIG. 4 shows another embodiment, in which the same parts as in the previous embodiment are designated by the same reference numerals and their explanations are omitted.

In this embodiment, the cap 15 and the stopper 11 of the closure member are formed integrally, and an inclined surface 16B is formed on the shoulder of the spouting cylinder part 5, and the protrusions on both sides of the cap 15 are formed on this inclined surface 16B. It is formed so that the portion 6B comes into contact with it.

In addition, in the above two embodiments, the inclined surface 16
It is also possible to form the protrusions 6A and 6B that come into contact with A and 16B into slopes, and make both surfaces of the abutting portions slopes.

[Effect of idea]

In the present invention, a spouting cylinder part 5 is attached to a spouting cylinder 2 of a container body 1.
The cap 15 is fitted onto the spouting cylinder 5, and the protrusion 6 is formed on one side of the shoulder of the spouting cylinder 5 and the lower end of the side of the cap 15, and the protrusion 6 is formed on the other side. An inclined surface 16 is formed.

Therefore, according to the present invention, the length from the lower end of the side portion of the cap 15, that is, the lower end contacting the shoulder of the spouting cylinder portion 5, to the top of the cap can be shortened.

Therefore, in the present invention, even if the side portions of the cap 15 are made thin, when the side portions of the cap 15 are pressed,
The central part of the side part does not curve to bulge outward, and the cap 15 can be reliably pushed upward to disengage the cap 15 from the spouting cylinder part 5.

Therefore, the present invention provides a container in which the side part of the cap 15 can be formed into a thin wall that is easy to operate, and the cap 15 can be reliably removed from the spouting cylinder part 5 despite the thin wall. It can be a mouth closure device.
