Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a container whose spout can be opened and closed by attaching and detaching the outer stopper with a single touch.

<Prior art> In conventional containers of this kind, screws are provided on the neck of the bottle and the lid that covers the neck.
A common technique was to screw a lid onto the mouth and neck to seal the mouth and neck.

However, a container in which the lid is screwed onto the neck of the bottle has a problem in that it takes time to open and close.

In order to improve this problem, we have created an inner stopper with a cylindrical body with a spout formed on the top that hangs down from the ceiling, and a closing rod that can be fitted into the cylinder of the inner stopper and close the spout from the ceiling. A container has also been developed in which the spout can be opened and closed by attaching and detaching the outer cap with a single touch in combination with a hanging outer cap.

<Problem to be solved by the invention> However, even in the latter of the above-mentioned conventional techniques, the inner diameter of the mouth neck of the bottle, the inner and outer diameters of the inner stopper cylinder having the spout, or the outer diameter of the closing rod. There was a problem in that it became difficult to maintain airtightness if there were any variations in dimensions.

Furthermore, in this latter technique, when used for many years, the above-mentioned parts become fatigued, which also poses problems such as impeding the maintenance of airtightness.

The present invention relates to a completely new technique developed in view of these conventional problems.

<Means for solving the problem> The present invention is a new technology developed to solve these conventional problems. In a container consisting of an inner stopper with a cylindrical body serving as a pouring spout hanging from the center of the ceiling, and an outer stopper with a closing rod that can be fitted into the cylindrical body hanging from the center of the ceiling, the cylindrical body of the inner stopper An elastic ring that can contract the cylinder is fitted around the cylinder.

<Function> As mentioned above, in the container according to the present invention, an elastic ring capable of contracting the cylinder is fitted around the cylinder of the inner stopper, so that it can be inserted into the cylinder of the inner stopper. The closing rod of the outer stopper can be elastically surrounded by the cylindrical body, thereby maintaining the airtightness of the spout, absorbing variations in component parts, and reducing fatigue caused by use. can be reduced.

<Example> To specifically explain one embodiment of the container according to the present invention with reference to the drawings, in FIGS. 1 and 2, 1 is the neck of the bottle 2, and the upper part of the neck A collar 3 is provided protruding from the outer periphery. Next, reference numeral 4 denotes an inner stopper that is covered with this mouth and neck part 1, and a cylinder 6 that can form a spout 5 is suspended from the center of the inner stopper, and a ring-shaped outer circumference of the lower part of this cylinder 6 is suspended. Tsuba 7 is installed protrudingly,
Moreover, the collar 3 of the neck part 1 is attached to the upper part of the inner peripheral surface of the inner stopper 4.
A ring groove 8 into which the ring can be inserted and locked is provided protrudingly. Reference numeral 9 denotes an elastic O-ring-shaped elastic ring made of silicone resin or the like, which is fitted around the lower part of the cylinder 6 so that the cylinder 6 can be contracted. It is being Furthermore, 10 is an outer stopper that can be covered with the inner stopper 4,
A hollow closing rod 12 having a ring-shaped wide-diameter portion 11 at its lower end and capable of fitting and locking into the spout 5 of the inner stopper 4 is provided to hang down and protrude from the ceiling.

In assembling the container according to the present invention, an elastic ring 9 is fitted and attached around the cylinder 6, and while the cylinder 6 is inserted into the opening of the neck part 1 of the bottle 2, the inside The whole is assembled by fitting and fixing the stopper 4 into the mouth and neck part 1, and then covering the inner stopper 4 with the outer stopper 10 while inserting the closing rod 12 into the spout 5 of the cylinder body 6. You can.

In the above embodiment, the inner plug 4 has a structure in which the cylindrical body 6 is single and the elastic ring 9 fitted around the cylindrical body 6 is exposed. However, as shown in FIG. 3, the cylindrical body 6 A skirt wall 13 is hung on the outside of the
It is also possible to configure this so that the elastic ring 9 fitted on the outside of the cylindrical body 6 is covered.

Furthermore, as shown in FIG. 4, the inner plug 4 is a double annular cylinder 14 in which an outer cylinder and an inner cylinder are arranged concentrically, and these are connected to each other at the bottom, and the upper end of the inner cylinder is open. It is also possible to construct a structure in which an elastic ring 9 is inserted between the inner cylinder and the outer cylinder so that the inner cylinder can be contracted by the elastic ring 9.

<Effects of the invention> As described above, in the present invention, a cylindrical body capable of forming a spout at the top of the inner stopper is suspended from the ceiling, and a closing rod is attached from the ceiling of the outer stopper that is covered with the inner stopper. Since the spout is configured to hang down, the spout can be reliably closed with one touch by inserting the closing rod into the cylinder, and an elastic ring is fitted around the cylinder. It has the characteristics of increasing the shrinkage force of the cylinder, thereby increasing the sealing effect around the spout, and being able to absorb variations in dimensions of the cylinder, closing rod, etc.
