Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a pot, and more particularly to a structure for sealing the mouth of a liquid container.

[Conventional technology]

Conventionally, in the pot, in order to achieve a seal between the mouth of the liquid container housed inside the pot and the stopper of the shoulder body, the liquid is attached to the ring-shaped seal member attached to the inner circumference of the lower surface of the stopper. The structure is such that the mouth of the container is pressed.

[Problems to be solved by the device]

In the pot with the above structure, the diameter of the shoulder plug is
It is formed in a size that matches the diameter of the mouth of the liquid container.
For this reason, when the diameter of the liquid container changes, the diameter of the shoulder body also changes, so that it is necessary to change the sizes of the shoulder body and the inner plug. However, since these various parts are molded products of synthetic resin, different molding dies are required for each size,
It was a cause of high manufacturing cost.

Therefore, the present invention has a technical problem of reducing the manufacturing cost of the pot, and an object thereof is to enable the use of uniform sized and shaped parts as the above parts regardless of the size of the diameter of the liquid container. And

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the first technical means of the present invention is a pot formed by pressing the mouth part of a liquid container against the stopper of the shoulder body through the sealing means, Positioning ribs are provided on the outside at a distance larger than the width of the peripheral wall of the mouth of the liquid container, the sealing means is composed of a first seal member, a second seal member and an intermediate ring, and the first seal member is a plug port. And the intermediate ring, the second seal member is provided between the downward inner peripheral wall of the intermediate ring and the inner peripheral wall of the mouth of the liquid container, and the outer peripheral edge of the intermediate ring is the inner diameter surface of the positioning rib. It is configured to fit in.

Further, the second technical means for achieving the above object is a pot formed by pressing the mouth of the liquid container through the sealing means to the stopper of the shoulder body, and the liquid container is placed outside the stopper of the rising shoulder. Positioning ribs are provided at intervals larger than the width of the mouth peripheral wall, and the sealing means is constituted by a seal member containing a reinforcing core material, and the outer diameter surface of the mouth portion of the liquid container is fitted to the inner diameter surface of the positioning rib. It has a structure.

[Action]

The pot of the first technical means has various caliber sizes of the liquid container only by changing the sizes and shapes of the intermediate ring and the second seal member without changing the sizes and shapes of the inner plug, the shoulder body and the first seal member. It can accommodate different things.
Further, in the case of a liquid container having a small diameter size, it is also possible to omit the intermediate ring and the second seal member and directly press the mouth portion of the liquid container against the first seal member.

The pot of the above-mentioned second technical means uses various sizes as the size of the sealing member containing the reinforcing core material, so that the diameter size of the liquid container is different without changing the size and shape of the inner plug and the shoulder body. Can correspond to. Further, in the case of a liquid container having a small caliber size, a normal sealing member is used instead of the above-mentioned reinforcing core-containing sealing member.
It is also possible to attach the seal member to the stopper of the shoulder body and press it with the mouth of the liquid container.

〔Example〕

In the pot of the first embodiment shown in FIGS. 1 and 2, the mouth of the liquid container 1 faces below the stopper 3 (see FIG. 2) of the shoulder body 2. A ring-shaped first seal member 4 that covers the range from the inner circumference to the outer circumference
Is installed. The inner peripheral surface of the seal member 4 is in close contact with the outer peripheral surface of the inner plug 5, thereby achieving a seal between the plug opening 3 of the shoulder body 2 and the inner plug 5.

Positioning ribs 12 projecting from the lower surface of the shoulder body 2 are provided outside the plug opening 3 of the shoulder body 2 at required intervals. The gap between the stopper port 3 and the positioning rib 12 is formed to be larger than the width W of the peripheral wall of the mouth of the liquid container 1.

An intermediate ring 13 is interposed between the first seal member and the positioning rib 12 described above. The intermediate ring 13 is shown in FIGS.
As shown in the drawing, the inner peripheral wall 16 is formed downward on the inner periphery of the horizontal portion 15, and the outer peripheral wall 17 is formed upward on the outer periphery. The inner peripheral wall 16 is formed to have a diameter that fits the inner periphery of the mouth of the liquid container 1, and the outer peripheral wall 17 is formed to have a diameter that contacts the inner peripheral surface of the positioning rib 12 to position the intermediate ring 13.

The radius of the shoulder portion 18 at the corner portion between the inner peripheral wall 16 and the horizontal portion 15 is the shoulder portion 6 of the minimum size liquid container 1 (see FIG. 4).
The inner peripheral wall 16 is positioned so as to match the radius R of the liquid container 1 and positions the mouth of the liquid container 1.

A second seal member 14 is attached to the outer peripheral corners of the inner peripheral wall 16 and the horizontal portion 15 of the intermediate ring 13, and the second seal member 14 presses the shoulder portion 6 on the inner peripheral portion of the mouth of the liquid container 1. And seal.

In FIG. 1, 7 is an air pump, 8 is a pumping pipe, 9 is a discharge port, 10 is a shoulder cover, and 11 is a body.

The liquid container 1 shown in FIGS. 1 and 2 shows the case of the liquid container 1 having the largest diameter. However, in the case of the intermediate size, the intermediate ring 13 and the second seal member 14 are adapted to the size. Select the one with the required size and shape. in this case,
The diameter of the inner peripheral wall 16 of the intermediate ring 13 varies depending on the caliber size, but the outer peripheral wall 17 is formed to have a diameter that contacts the inner peripheral surface of the positioning rib 12 regardless of the caliber size.

The positioning rib 12 is the maximum size of the diameter of the liquid container 1,
It serves as a guide when the intermediate ring 13 is attached regardless of the intermediate size.

When the diameter of the liquid container 1 is small, the intermediate ring 13 and the second seal member 14 are omitted and the shoulder portion 6 on the inner circumference of the mouth of the liquid container 1 is directly sealed as shown in FIG. The member 4 may be pressed.

The seal member 19 in the case of the second embodiment shown in FIG. 5 has a portion that seals between the stopper 3 and the inner stopper 5 of the shoulder body 2, and also has the stopper 3 and the mouth of the liquid container 1. A mouth seal portion 21 that seals between the two is formed. The reinforcing core member 20 is integrally fixed to the lower surface of the seal member 19, whereby the seal member 19
To reinforce.

Further, the mouth of the liquid container 1 contacts the inner peripheral surface of the positioning rib 12, whereby the liquid container 1 is positioned.
If the diameter of the liquid container 1 is small, the sealing member 19
As shown in FIG. 4, it is possible to use the first seal member 4 in the case of the first embodiment and press the mouth portion against it.

[Effect of device]

As described above, in the device according to the first technical means, the inner plug, the shoulder body, and the first seal member are changed by changing the size and shape of the intermediate ring and the second seal member or omitting them. Therefore, it is possible to deal with liquid containers having different caliber sizes.

Further, regarding the device according to the second technical means, by using a seal member having a reinforcing core material or omitting the seal member and using the same one as the above-mentioned first seal member, an inner plug and a shoulder body are provided. It is possible to support liquid containers of two different sizes without changing the size.
