Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container with an opening / closing cap.

[0002]

2. Description of the Related Art Generally, a container having an opening / closing cap for accommodating a liquid seasoning such as a sauce is shown in FIG.

[0003] That is, the inner stopper 3 is attached to the mouthpiece 31 of the container body 30.
2 is fitted inside, and a flange portion 33 is provided around the inner plug 32. The lower surface of the flange 33 is in close contact with the upper edge of the mouthpiece 31.

[0004] The inner plug 32 is formed with an annular spout 34 that expands toward the tip, and a removable portion 36 surrounded by a thin groove 35 is formed on the inner periphery of the base of the spout 34. Have been. The removable portion 36 is provided with a ring-shaped finger portion, a so-called ring pull 37,
When the ring pull 37 is pulled, the thin groove 35 is cut and the removable portion 36 can be removed. The outer stopper 38 is detachably fitted to the mouthpiece 31.

[0005] In use, after the outer plug 38 is taken and the ring pull 37 is pulled to open, the outer plug 38 is attached and detached.
It is designed to be poured and sealed.

[0006]

However, in the above-mentioned prior art, since the inner plug 32 is fixed only by the fitting force with the mouthpiece portion 31, the inner plug 32 comes out by an impact such as dropping. There is a possibility that it will happen. In this case, the sealing may not be performed completely and the contents may not be sufficiently protected.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a highly reliable container with an opening / closing cap that can completely fix an inner plug.

[0008]

Means for Solving the Problems The present invention has the following configuration in order to solve the above technical problems. That is, an inner plug is fitted into the mouthpiece of the container body, a flange is provided around the inner stopper, and a packing convex portion is formed on at least the lower surface of the flange to face the mouthpiece. The packing convex portion arranged at the site is brought into close contact with the upper edge of the mouthpiece portion, and a flexible annular spout is formed on the outer surface of the inner plug so as to extend toward the tip and form a flexible spout. Forming a removable portion that is surrounded by a thin groove on the inner periphery of the base and that can be removed from the base of the spout, and that an outer plug is plugged into the mouthpiece, and the inner wall of the outer plug is pressed against the upper surface of the flange. A pressable flange is provided, and an openable and closable lid is formed on the outer plug . When the lid is closed, the lid is closed.
The inner surface is pressed against the upper end of the spout and the tip of the spout
Seal the periphery and secure the inner plug through the spout.
It was configured to be able to set.

[0009]

[0010]

[Function] Provided on at least the lower surface of a flange portion provided around the inner plug.
Since the packing convex part thus pressed is crushed at least between the upper edge of the mouthpiece part and the flange part , the sealing property becomes extremely good, and the packing convex part is firmly fixed by the outer plug which is plugged.

Therefore, even if the container falls, there is no risk of the inner and outer plugs coming off, and the contents can be protected reliably.

[0012] Further, a flexible annular spout is formed on the outer surface of the inner plug so as to expand toward the tip, and a lid is formed.
When closed, the inner surface of the lid presses against the
When the inner plug is pressed through the spout so that the inner surface of the lid deforms the spout against the elasticity of the spout so as to be able to seal the periphery of the tip of the spout, the seal after opening is sealed. The property is good, and the deterioration of the contents can be prevented. Therefore, the inner plug is pressed while securing the airtightness after opening the lid.
The inner stopper can be prevented from falling out of the mouthpiece of the container body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIG.

A barrel 2 is provided on the container body 1, and an engagement projection 2a is formed on the outer periphery of the barrel 2. An inner plug 3 is fitted inside the mouthpiece 2. This inner plug 3
A flange 4 is provided around the outer periphery of the skirt 3a, and an annular spout 7 is formed from the upper part of the skirt 3a to the tip of the skirt 3a. The collar 4
One and the other packing projections 5 and 6 are formed on both surfaces of each of these, and these projections 5 and 6 have a total of two projections, one inside and one outside.

One of the packing projections 5 facing the mouthpiece 2 is brought into close contact with the upper edge of the mouthpiece.

A removable portion 9 surrounded by a thin groove 8 is formed on the inner periphery of the base of the spout 7. A finger hanging portion 9a is provided upright on the removable portion 9, and when the finger hanging portion 9a is pulled, the thin groove 8 is cut and the removable portion 9 can be removed.

On the other hand, an outer plug 10 is plugged in the mouthpiece 2. The inner wall of the outer plug 10 is provided with a pressing flange 11 which presses against the other packing convex portion 6, and the outer plug 10 is provided with a lid 12 which can be opened and closed via a hinge 10 b. The hinge portion 10b is an inverted hinge, and click stops at the positions indicated by the solid line and the dotted line in the figure. Further, a finger pad 12 a is formed at the tip of the lid 12.

[0018] Then, this is the inner wall of the outer plug 10 engaging portion 10a to be fitted to the engaging projection 2a is formed so as not come off easier once fitted to engagement. The lid 12 abuts against the tip of the spout 7 on its back surface,
The spout 7 is deformed in the direction of arrow F against the elasticity,
7 is formed so as to hermetically seal the peripheral edge thereof, so that when sealed , the adhesion of the lid 12 is good.
