Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement in a gasket used in the spout portion of various containers including tanks carried when camping.

[Conventional technology]

Conventionally, this type of gasket generally performs a sealing action by bringing both the upper and lower end surfaces into close contact with the spout and the spout pipe.

[The problem that the idea attempts to solve]

If the position of the spout is fixed, the direction of pouring is naturally limited, making the pouring process difficult. Therefore, it is recommended to attach an L-shaped spout pipe to the spout of the container so that it can rotate freely. It is proposed to make it possible. In this case, a gasket is inserted between the connection part of the spout and the spout pipe to seal this part, but if the gasket that has been commonly used in the past is used here, the spout pipe I can't shake my head.

This is because, in order to fully utilize the sealing effect, it is necessary to press the spout from above and below, which makes it difficult for the spout pipe to move freely.

The present invention is a gasket that is advantageous when a spout pipe is rotatably attached to a spout, and is capable of performing a sufficient sealing action without hindering the rotation of the spout pipe. With the goal.

[Means to solve the problem]

In order to achieve this purpose, the present invention provides a cap-shaped cap 4 for the spout 2 of the container 1, and a peripheral wall near the lower end of the L-shaped spout pipe 3 attached to the spout 2. A connecting body 3a is formed outwardly from 3c, and the cylindrical portion 3b of the connecting body 3a is rotatably engaged with the cylindrical portion 4a of the cap 4, so that the neck of the spouting pipe 3 can be swung. So,
A connecting portion between the spout pipe 3 and spout 2 is sealed by interposing it in an annular space 5 between the outer peripheral surface of the peripheral wall 3c of the spout pipe 3 and the inner peripheral surface of the cylindrical portion 4a of the cap 4. It is a ring-shaped gasket used for this purpose, and its cross-sectional shape is such that double inner and outer hanging walls 6b and 6c are integrally formed from the lower end of the roof part 6a, which has an inverted V-shaped cross section, and the inside thereof is hollow. The outer hanging wall 6 of the double inner and outer hanging walls.
The outer surface of the pipe c is brought into close contact with the inner peripheral surface of the cylindrical portion 4a of the cap 4, and the outer surface of the inner hanging wall 6b is brought into close contact with the outer peripheral surface of the peripheral wall 3c of the spouting pipe 3 to form a seal. .

[Effect]

When this gasket 6 is fitted into the space 5, the gasket 6 is deformed to some extent as shown by the dotted line in FIG. In addition, the outer surface of the inner hanging wall 6b comes into close contact with the outer circumferential surface of the peripheral wall 3c of the spouting pipe 3, and the connecting portion between the spout 2 and the spouting pipe 3 is sealed at this part. On the other hand, the roof part 6a, which has an inverted V-shaped cross section, is pushed to some extent by the lower surface of the connecting body 3a of the spouting pipe 3, and the vertical movement of the gasket 6 is appropriately regulated.

〔Example〕

Embodiments of the present invention will be described based on the drawings.

As shown in Figures 3 and 4, a cap-shaped cap 4 is screwed onto the spout 2 of the portable container 1, and an L-shaped spouting pipe 3 is rotatably attached to the cap 4. . In order to prevent the spouting pipe 3 from falling off, a cylindrical portion 3b of the connecting body 3a, which is integrally provided outward from the peripheral wall 3c near the lower end of the spouting pipe 3, is attached to the cylindrical portion 4a protruding from the cap 4. Rotatably engage.

Peripheral wall 3c of the pouring pipe 3 at this connection part
A ring-shaped packing 6 as shown in FIG. 1 is interposed in an annular space 5 (FIG. 4) between the outer circumferential surface and the inner circumferential surface of the cylindrical portion 4a of the cap 4.

As shown in FIG. 2, the cross-sectional shape of the packing 6 is such that double inner and outer hanging walls 6b and 6c are integrally formed from the lower end of the roof part 6a, which has an inverted V-shaped cross section, and the inside thereof is hollow. It is the shape.

When this gasket 6 is fitted into the space 5, the gasket 6 is pressed and deformed somewhat as shown by the dotted line in FIG. The outer surface of the inner hanging wall 6b is in close contact with the outer circumferential surface of the circumferential wall 3c of the spouting pipe 3.
At this portion, the connecting portion between the spout 2 and the spout pipe 3 is sealed.

On the other hand, the roof part 6a having an inverted V-shaped cross section is pushed to some extent by the lower surface of the connecting body 3a of the spouting pipe 3,
The vertical movement of is moderately regulated.

Note that, as shown in FIG.
Multiple pieces (3 in the drawing) protrude from the center toward the center.
It is located on the protrusion 4c of 1) and is prevented from falling downward.

In the case of the embodiment, a grip part 7 is provided horizontally in the upper part of the container 1, and a tubular water stop valve 8 is attached to one end (closer to the spout 2) of the grip part 7 so that it can be freely advanced and retracted (as shown in FIGS. 3 and 4). It is provided in the horizontal direction) and is rotatable with respect to the grip portion 7. The stopcock 8 is removably attached to the tip of the spouting pipe 3 (in the drawing, it is screwed together), and the opening at the tip of the spouting pipe 3 can be closed using the stopcock 8. I can do it. That is, to stop the water after pouring, return the spout pipe 3 from the state indicated by the dotted line in Figure 3 to its original state so that the tip of the spout pipe 3 is on the same straight line as the grip 7, and then stop the water. The faucet 8 is engaged with the tip of the spout pipe 3. In this way, as shown in FIGS. 3 and 4, the spouting pipe 3 and the grip part 7 are connected by the water stop valve 8, and the tip opening of the spouting pipe 3 is closed, even after water is poured. It is true. In addition, pouring pipe 3
Its rotation is prevented by the stop valve 8, so there is no fear of water leakage, and since the spout pipe 3 becomes part of the grip part 7, it does not get in the way.

In addition, in the drawing (FIG. 5), 9 is a drain hole.

[Effect of idea]

In the present invention, the packing 6 has a cross-sectional shape, and of the double inner and outer hanging walls, the outer hanging wall 6c
The outer surface of the cap 4 is brought into close contact with the inner peripheral surface of the cylindrical portion 4a of the cap 4, and the outer surface of the inner hanging wall 6b is brought into close contact with the outer peripheral surface of the peripheral wall 3c of the spouting pipe 3 for sealing. The rotation of the spout pipe 3 is not obstructed, unlike when using gaskets that perform a sealing action on both the upper and lower end surfaces.
Furthermore, the sealing effect is not diminished in any way.

Therefore, when dispensing the liquid in the container 1 through the dispensing pipe 3, for example, there is no problem in turning the dispensing pipe 3 and shaking its head as shown by the dotted line in FIG. Furthermore, there is no fear of liquid leaking from the connection between the spout 2 and the spout pipe 3.
