Description

[Detailed Description of the Invention] This invention relates to a liquid container used to contain liquid such as drinking water.

2. Description of the Related Art Relatively large liquid containers are used for recreational purposes and the like, and are constructed so that the liquid contained therein is discharged to the outside through a liquid dispensing path with a valve.

Rotary valves such as screw-type valves and cock-type valves have been adopted as valves for opening and closing the liquid pouring passage, but screw-type valves are inconvenient because they require time and effort to open and close, so they lack quick response and are inconvenient. Since the cock-type valve has a protruding lever for opening and closing, it is easy to open the valve when it comes into contact with objects during transportation, making it easy for accidental pouring to occur.

A push-button type valve could be considered as an improvement to this problem, but a push-button type valve has to be kept pressed during liquid injection, which is inconvenient for continuous liquid injection.

The present invention was developed in view of the above circumstances, and aims to provide a liquid container equipped with a valve that is easy to open and close, is highly responsive, and can be kept open as necessary. Yes, and this will be explained below.

The liquid container according to the present invention houses an intermediate container for storing liquid inside the container body, and has a liquid outlet opening at the tip of a liquid outlet opening near the bottom of the container facing outside the container. A liquid container configured to pour out the liquid in the container, wherein the liquid pouring path is provided with a valve that is normally closed by a spring, and the valve is opened by pressing against the spring. The member has its operating portion facing the side wall of the container, and its movement is guided by a guide member provided between the side wall of the container and the inner container, and the guide member has a valve opening for the operating member. It is characterized by the provision of a retaining portion that maintains the valve posture during this engagement.

Hereinafter, embodiments of the present invention shown in the drawings will be described.

FIG. 1 is a front view of an example of a liquid container according to this invention, FIG. 2 is a sectional view taken along the line AA, and FIG. 3 is a partially omitted bottom view.

In these figures, the liquid container 1 includes a container body 2, an outer lid 3 that covers an opening 2a of the container body 2, and
It has a liquid injection port 4 provided at the bottom of the container body 2, legs 5 for supporting the container body, and a handle 6.

The container body 2 is formed by housing an inner container 9 inside an outer case 7 with a heat insulating material 8 interposed therebetween.

The outer case 7 includes a cylindrical part 71 made of a decorative steel plate, and a shoulder member 72 and a bottom member 73 made of synthetic resin. They are joined by a so-called force fit method.

The middle container 9 is made of a metal material such as aluminum or stainless steel, and a container member 91 and an upper member 92, which are manufactured separately, are swaged together at the joint 9a to form the middle container. is forming.

The upper end periphery of this upper member 92 is bent outward and attached to the edge 9b, which is attached to the upper end of the support ring 10.

As a method for attaching the upper member 92 of the medium container to the support ring 10, when the upper end of the upper member 92 is bent, the upper end periphery of the support ring 10 may be rolled up and crimped at the same time. The upper member 92 may be attached to the opening member 11 to which the support ring 10 is screwed, and the upper member 92 may be held by pressing the edge 9b through the gasket 12.

In this way, the inner container 9 is attached to and held by the outer case 7 mainly at its upper end, but is also auxiliary supported by the heat insulating material 8 disposed below its lower end.

A hanging piece 11d is provided respectively.

A backing 12 is provided in the concave portion below the opening peripheral portion 11a.
is provided, and the inner container is attached to the edge 9b.

Further, this opening peripheral portion 11a is partially cut out to form an air passage 11e, and this air passage 11e
serves as an air suction port necessary for pouring out the liquid from the liquid inlet 4.

The support ring 10 is attached to the internal thread 11b of the mouth member 11.
The outer circumferential screw 10a is screwed together, and the outer cover 3 is screwed onto the outer screw 11C.

The support ring 10 has a plurality of reinforcing ribs 10C and a stopper 10b, and the stopper 10b is in contact with the hanging piece 11d of the spout member 11, thereby opening the inner container for attaching the liquid filling port 4. is positioned, and the opening member 11 and the support ring 10 are in a favorable screwed state.

Note that the mouth member 11 is attached to the shoulder member 72 at the fixed portion 72a.
However, the mouth member 11 and the shoulder member 72 may be integrally formed into a bottom shape.

The outer lid 3 covers the opening 2a of the container body 2 (which is also the opening of the inner container) in a manner that allows it to be opened and closed.In the illustrated example, the outer lid 3 is screwed onto the mouth member 11, but it can be opened and closed in a hinged manner. To,
It may also be pivotally attached to the container body.

Cups 3 a and 3 b are held inside the outer lid 3, and it is practically convenient to store the cups by utilizing the space of the opening 2a in this way.

A protective cover 14 is provided on the side surface of the container body 2, and a liquid level meter 13 is provided inside the protective cover 14.

The liquid level meter 13 has caps 13a and 13b provided on the middle container 9.
Transparent glass tubes 13e are connected to the tubes through rubber elbows 13C and 13d, respectively. Providing these tubes is convenient because the liquid level can be observed at all times.

The lower end of the container body 2 is provided with three legs 5.5', 5''.

These three legs 5.5', 5'' are attached to the bottom member 73 with pins 5.

They are provided as so-called foldable legs.

Furthermore, the three legs 5.5', 5'' are mounted symmetrically with an interval of 120° from each other.

Since a container such as a pot is placed under the liquid injection port 4, it is preferable to provide a plurality of legs to support the container body in order to secure a space for it. In this case, the number of legs is It is advantageous in terms of stability and economy to install three pieces at equal intervals as shown in the illustrated example.

Note that it is more convenient to carry these legs if they are provided in a foldable manner as shown in the illustrated example.

The liquid filling port 4 forms the tip of a liquid pouring path that opens at the bottom of the medium container 9, and is provided so as to protrude from the lower side surface of the container body 2.

In the liquid spouting passage, a cap 16 attached to the bottom of the medium container 9 via a gasket 15 is connected to a valve chamber 18 via an elbow 17, and a spout 16 protruding to the outside is connected to the valve chamber 18. It is formed by connecting tubes 19.

The end of the cap 16 on the side of the inner container has a slightly raised spherical shape, and a plurality of pores 16b are formed therein to form the filter part 16.
It is a.

The liquid held in the inner container passes through this filter part 1.
The liquid is poured out from the injection port through the pore 16b of 6a,
At this time, tea leaves and the like placed in the medium container are prevented from flowing into the liquid pouring path by this filter portion 16a.

Further, since the cap 16 is attached to the bottom surface of the middle container 9 and the liquid flows downward from the middle container, almost the entire amount of the liquid in the middle container can flow out.

Incidentally, since a portion of the filter is formed as a somewhat raised curved surface, the pores are prevented from being blocked by ice blocks or the like placed in the medium container.

an inflow pipe 18a connected to the elbow 17 of the valve chamber 18;
An opening/closing opening 18C is provided between the outflow pipe 18b connected to the pouring pipe 19, and a liquid reservoir 18d is provided below the opening/closing opening 18C.

The opening/closing port 18C is provided with a gasket 20 at the lower end of the valve shaft 20a.
It is closed by a valve 20 formed by fixing b.

A guide cylinder 18e is provided in the upper part of the valve chamber 18, and the upper part of the valve shaft 20a is fitted into this.

A bushing 20C is attached to the upper end of the valve shaft 20a, and this bushing 20C partially fits into the guide cylinder 18e, and its lower end surface is
Spring 2 housed inside guide tube 18e
It is constantly pushed upward by 0 d.

Therefore, the valve 20 normally keeps the opening/closing port 18C closed.

Note that the valve 20 slides diagonally up and down by external force to open and close the opening/closing port 18C, but at this time, the guide tube 18
The movement of the valve 20 is guided by the sliding movement between the side wall of the shaft hole 18g provided in the bottom surface 18f of the valve shaft 20a and the sliding movement between the bushing 20C and the inner surface of the guide cylinder.

The outflow pipe 18b of the valve chamber 18 is provided above the inflow pipe 18a.

Therefore, the liquid from the medium container flows from the inflow pipe 18a through the liquid reservoir 18d and through the opening/closing port 18C from bottom to top. Since the valve 20 is directed from the bottom to the top, the valve 20 always receives water pressure in the direction of closing the opening/closing port 18C, thereby making it more reliable to close the liquid outlet path in the normal state.

Note that the lower end of the liquid reservoir 18d is formed as an opening, but this opening is closed by the cap 21.

At the position where the liquid pouring path is provided, the bottom member 73
is partially cut out to form an open lower lower part 3a, and the bottom plate 22 is disposed in that part while being placed on the bottom member 73.

The portion of the bottom plate 22 that is in contact with the liquid reservoir 18d is partially formed into a concave shape, and serves as a seat 22a for the valve chamber 18.

An operating member 23 is provided above the valve 20 and is inclined in the same direction as the valve shaft 20a.

The head 23C of the operating member 23 functions as an operating section for operating the valve 20, and is provided inside the recess 14a of the protective cover 14 so as to face the outside from the side wall of the container.

The operating member 23 includes an inclined wall 14b that reaches from the recess 14a of the protective cover 14 to the space between the outer case 2 and the inner container 9, and upper and lower support plates 14C provided in the recess 14a.
, 14d, inside thereof there is a spring 23a that constantly pushes the operating member 23 upward, and on the outside there is a slit H4e provided on the inclined wall 14b.
A stopper 23b is provided, which is fitted into and moves up and down along the stopper 23b.

Therefore, the operating member 23 is normally operated by the stopper 23.
b is held in a state where it abuts against the upper end of the slot H4e, and in this state, a gap 24 is formed between the lower end of the operating member and the upper end of the valve shaft 20a.
3, the inclined wall 14b and the upper and lower supporting plates 14C, 14 are pressed downward.
d as a guide, and after coming into contact with the upper end of the valve shaft 20a, the valve shaft 20a is slid downward to open the opening/closing port 18C.

In this liquid container, the sliding directions of the operating member 23 and the valve shaft 20a when opening the valve 20 are aligned in the same direction,
Its sliding direction (also the pressing direction to open the valve) is
It is a diagonally downward direction that is inclined toward the central axis of the container body.

In addition, in the illustrated example liquid container, the liquid inlet 4 and the operating member 23 are mounted approximately in the space between the two legs 5' and 5'' that are spaced apart by 120°. are doing.

By doing this, the pressure to open the valve will be applied equally to the legs on both sides, which is advantageous in terms of stability, and since there are no legs directly below the injection port, it will be easier to hold the valve open. It has the advantage of providing space for storage.

Next, in the embodiment shown in FIG. 1, a locking piece 23d is provided on the upper outer periphery of the operating member 23,
Therefore, a space 25 is formed between the outer peripheral surface of the operating member 23 and the inclined wall 14b.

Therefore, if the operating member 23 is pushed down until the locking piece 23d is below the upper edge 14f of the slot H4e and then the head is swung in the direction of arrow A, the locking piece 23d will touch this upper edge 14f. , and the operating member is fixed in that state.

This keeps the valve open.

That is, the upper edge 14f of the slit 14e serves as a retaining portion that engages with the operating member in the valve open state and maintains the valve open position.

To close the valve again, simply swing the operating member in the direction opposite to arrow A.

By this operation, the locking piece 23d is released from the retaining portion, and the operating member 23 is moved by the action of the spring 23a.
Further, the valves 20 are immediately returned to their original positions by the action of the springs 20d, and the injection of liquid is stopped.

FIG. 4 is a sectional view of an operating member according to another embodiment. For example, a stopper 23b is provided on the opposite side of the slit 14e, and by abutting against the upper support plate 14C, the operating member It is designed to prevent protrusion.

At the upper end of the slimmer H4e, the lower end of the inclined wall is recessed toward the inner container to form a recess 14g.

In this case, if you push down the head 23C of the operating member 23 until it is below the upper edge 14f and swing it in the direction of arrow A as in the example in FIG. 2, the head 23C becomes the engaging part. Since it is locked to the upper edge 14f, the valve can be held in an open state.

To close the valve again, swing the head 23C of the operating member 23 in the direction opposite to arrow A, and the operating member will release the spring 23.
Due to the action of a, it returns immediately and the liquid injection is stopped.

The recess 14g serves to prevent the operating member 23 from deviating toward the inner container.

FIG. 5 shows that a small locking projection 26 is provided on the upper outer peripheral surface of the operating member 23, and by locking this locking projection 26 in a locking hole 27 provided on the surface of the inclined wall 14b, the valve can be opened. Here's an example of how you can hold it open.

In this example, the locking hole 27 becomes the engaging portion.

FIG. 6 shows an example in which a locking protrusion 26' is provided on the inclined wall 14b side and a locking hole 27' is provided on the operating member 23 side, contrary to the example shown in FIG.

In this example, the locking protrusion 26' serves as the retaining portion.

FIG. 7 shows an example in which an elastic locking piece 28 is provided on the front side of the container body, in which a is a sectional view and b is an external view of the operating member 23.

This elastic locking piece 28 is formed integrally with the operating member 23, and is provided with a locking protrusion 28a on its front part. However, when the operating member 23 is pushed down sufficiently deeply, the locking protrusion 28
a reaches the lower end of the side wall 14h of the support plate 14C, at which time it restores itself in the direction of arrow B due to elasticity, and the locking protrusion 28
a to the lower end edge of the side wall 14h, which is the engaging portion, and fix the valve in an open state.

Note that if the amount of depression of the operating member is small, the valve will not be fixed in the open state, so if the pressing force is removed, the valve will close and liquid injection will stop.

A push button 29 is provided on the lower side of the support plate 14C.

This push button 29 is attached to a hole 29a provided on the front surface of the protective cover 14, and is normally pushed outward by a spring 29b, but if pushed in the direction of arrow C, The end portion 29C presses the lower part of the elastic locking piece 28 that has been pushed down, and the support plate 14
A locking protrusion 28 a that is locked to the lower edge of the side wall of C
release.

This causes the operating member 23 to rise and the open valve to close immediately.

FIG. 8 shows an example in which the operating member is fixed by a hook-shaped tool, in which a is a sectional view and b is an external view of the operating member.

In this example, the head 23C of the operating member 23 is partially cut out to form an opening, and the swinging piece 30 is pivotally attached to the opening by a pin 30b.

This swinging piece 30 has a hook-shaped tool 30a at its lower end,
It is normally pushed upward by a spring 30C.

When the valve is closed, the tip of the hook-shaped tool 30a is in contact with the side wall 14h of the support plate 14C, but the operating member 2
3 is pressed down sufficiently, the hook-shaped tool 30a will be attached to the side wall 14.
The hook-like tool 30a is pushed outward by the action of the spring 30C and is locked to the lower edge of the side wall 14h, which is a retaining portion.

This allows the valve to be individually identified in its closed state.

If you push the swinging piece 30 downward in this state, the hook-shaped tool 30
Since a is removed from the lower edge of the side wall 14h, the valve can be closed again.

Note that if the swinging piece 30 is always pressed, the valve will not be fixed in the open state.

FIG. 9 shows an example in which a rotationally fixed operating member is provided, in which a is a sectional view and b is a detailed view of the retaining portion.

In this example, a locking housing 31 is provided in the recess 14a of the protective cover, and a partial protruding plate 31a is provided on the inner wall of the locking housing 31.

The operating member 23 has a cylindrical upper end, a knob 32 on the upper surface, and a hook-shaped locking member 3 on the lower side.
3 is provided.

When opening the valve by operating this operating member, the locking member 3
The operating member may be pushed in while rotating the knob 32 so that the knob 3 passes through the gap between the protruding plates 31a.

In addition, in order to hold the valve in an open state, the locking member 33 is an engaging portion while pressing down the operating member so that the locking member 33 is located below the protruding plate 31a. All you have to do is turn the knob 32 so that it locks onto the protruding plate 31a.
Conversely, if the knob 32 is turned in a direction such that the locking member 33 is disengaged from the protruding plate 31a, the open valve can be closed again.

In either case, the operating member 23 is connected to the spring 23 H
Also, since the valve 20 is always pushed in the returning direction by the spring 20d, if the operating member 23 engaged with the retaining part is released, the injection of liquid is immediately stopped. be.

. Although the operating member 23 and the valve stem 20a may be formed integrally, it is better to provide them separately and provide a gap 24 between them, as shown in the illustrated example. This is advantageous because it prevents an accident in which the valve opens due to an external force.

Furthermore, it is better to position the head 23C of the operating member 23 inside the recess 14a of the protective cover as in the illustrated example.
This is advantageous because items are less likely to come into contact with each other while being carried.

In the liquid container according to the present invention, a valve that is always kept closed by a spring is provided in the liquid outlet path for the liquid inlet,
Since this valve is opened by pressing the operating member against a spring, the valve can be opened and closed by pressing and releasing the operating member, compared to conventional rotary operating mechanisms. It is easy to operate and has excellent quick response when opening and closing the valve.

The operating member is guided by a guide member provided between the side wall of the vessel body and the inner container, and this guide member has a retaining portion that engages with the operating member in the valve open state and maintains the valve posture during that time. This makes it possible to keep the valve open and perform continuous injection if necessary, while also leaving both hands free when pouring liquid into large-capacity containers or multiple containers. It became convenient.
