Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a liquid container such as a thermos flask.

(Prior Art) In recent years, a so-called low spout type liquid container has been developed in the art, which has a thick body and an external liquid spout located at a low position. In this case, in order to lower the external liquid inlet, it is necessary to provide an auxiliary pouring tube that communicates with the liquid pouring tube separately from the liquid pouring tube. Various proposals have been made in the past due to the need for ingenuity. For example, as described in Japanese Utility Model Application Publication No. 50-98371, the liquid spout pipe and the auxiliary spout pipe are directly connected, and the auxiliary spout pipe is covered with a pipe cover integrally formed on the side surface of the main body case. A thermos flask with this configuration has already been proposed.

(Problem to be solved by the invention) In the case of the above-mentioned known example, since the liquid pouring pipe and the continuous pouring auxiliary tube are directly connected, the liquid content is continuously poured out during liquid injection. When a siphon phenomenon occurs, in order to stop the liquid injection, it is necessary to provide an air venting mechanism to eliminate the siphon phenomenon, which has the problem of inevitably complicating the structure.

In order to eliminate the above-mentioned siphon phenomenon, as described in Japanese Utility Model Application Publication No. 49-148281, the liquid dispensing pipe and the dispensing auxiliary pipe should not be directly connected, but a space should be provided between them. However, in the case of a low spout type liquid container with a pipe cover, if the connection position between the two is above the shoulder member as described in the above publication, the height of the liquid spout pipe must be increased, and the liquid This goes against the original purpose of the low spout type, which is to make the container more compact.

In addition, in known low spout type liquid containers, as shown in Japanese Utility Model Application No. 119566/1983, a hole in the front protrusion of the shoulder member for facing the spout of the liquid spout pipe is provided on the lower surface side. It is known that the upper end of the auxiliary pouring tube is screwed onto the mouth rim so that the spout of the liquid pouring tube and the auxiliary pouring tube communicate with each other with a gap. Since the auxiliary pouring tube is attached to the container by screwing, it is necessary to screw the auxiliary pouring tube together (turning it many times) when attaching it, which poses a problem in that the work is troublesome. .

The present invention has been made in view of the above points, and
By optimizing the connection point between the liquid pouring tube and the pouring auxiliary tube, it is possible to not only make the liquid container more compact, but also to effectively eliminate the splash phenomenon and siphon phenomenon. The purpose is to facilitate the assembly of the outlet auxiliary pipe.

(Means for Solving the Problems) In the present invention, as a means for solving the above problems, as shown in the drawings, the inner container 2 is housed inside and the upper end portion has a dish-shaped upper surface. The main body case 1 is equipped with a shoulder member 5, and the liquid W in the medium container 2 can be poured out to the outside through a suitable liquid pouring pipe 11.
A low spout type configured to include a spout auxiliary pipe 23 that communicates with the spout 12 of the liquid spout 1 and guide the liquid to be spouted to the outside through the liquid spout pipe 11 further downward from the spout 12. In the liquid container, the spout 12 of the liquid spouting pipe 11 is opened at a position below the dish-shaped surface of the shoulder member 5 and above the liquid supply port 9 of the medium container 2, and The spout auxiliary pipe 23 is positioned so as to surround the spout 12 with an upper end opening 32 having an inner diameter larger than the outer diameter of the spout 12 and below the shoulder member 5. A pipe in which the upper end opening 32 is simply opposed to the lower surface of the shoulder member 5 and fixed by appropriate fixing means, and the outside of the auxiliary pouring pipe 23 is connected to the lower surface of the shoulder member 5. It is also covered with a cover 14.

(Function) In the present invention, the following effects can be obtained by the above means.

(1) Since the spout 12 of the liquid spouting pipe 11 is opened at a position below the dish-shaped surface of the shoulder member 5 and at a position above the liquid supply port 9 of the medium container 2, the liquid spouting pipe 11 height position, middle container 2
Even when the inside is full of liquid, the above-mentioned spout 12
The height of the liquid container can be kept as low as possible within a range where no siphon effect occurs, thereby making it possible to keep the height of the entire liquid container low.

(2) Since the upper end opening 32 of the auxiliary spouting pipe 23 is communicated with the spout 12 of the liquid spouting pipe 11 with a gap, the splash phenomenon that occurs when the content becomes low can be avoided by the spout 12 of the liquid spouting pipe 11. Although it occurs in the portion 12, it does not occur from the lower end opening of the auxiliary pouring pipe 23.

(3) Since the auxiliary spout pipe 23 is fixed by an appropriate fixing means with its upper end opening 32 simply opposed to the lower surface of the shoulder member 5, the installation work of the auxiliary spout pipe 23 is easy, for example. This can be done more easily than in the case of jointly connecting and fixing.

(4) Since the outside of the auxiliary pouring pipe 23 is covered with the pipe cover 14 connected to the lower surface of the shoulder member 5, it is possible to prevent external objects from directly colliding with the auxiliary pouring pipe 23. Liquid pouring pipe spout 12
and the auxiliary spout pipe 23, and when liquid is poured, a splash is ejected from the spout of the liquid spout pipe, and some of the water droplets pass through the gap and exit from the upper end opening of the auxiliary spout pipe 23. Even if water leaks to the outside, the leaked water drops will be absorbed into the pipe cover 14.
This prevents the liquid from spilling out of the container.

At this time, most of the vertical portion of the pipe cover 14 is made to protrude into a space S formed above the shoulder of the inner container 2 in the main case 1. At this time, the upper end of the pipe cover 14 is attached so as to come into contact with the lower surface of the shoulder member 5.

This pipe cover 14 is constructed by integrally molding both side walls 30, 30 and a rear wall 40, and a lid body 25, which will be described in detail later, is detachably attached to an opening 41 formed on the front surface of the pipe cover 14. There is.

Note that this pipe cover 14 is attached to the rear wall 40.
is fixed to a rib 17 installed in the middle part of the notch hole 13 with a screw 18, thereby preventing it from falling off to the outside.

At a position below the upper surface of the shoulder member 5, the spout 12 of the liquid spouting pipe 11 is exposed in the upper end opening 19 of the gutter groove 15, while the gutter groove 1
The lower end opening 20 of 5 is located at a position where the horizontal distance d from the side surface of the main body case 1 and the vertical distance h from the bottom surface of the main body case 1 are slightly larger than the radius and height of the liquid receiving container 21 such as a pot. . By doing so, the liquid injection work can be performed more reliably and easily.

On the bottom surface of the vertical groove portion 15a in the gutter groove 15,
A pair of upward L-shaped protrusions 22, 22 are integrally protruded at appropriate locations, and the protrusions 22, 22 have a holder 2 for holding an auxiliary pouring pipe 23, which will be described later.

As shown in FIG. 3, the holder 24 includes a plate-shaped mounting portion 24a and a pair of arm portions 24b, 24b having an arcuate inner surface integrally protruding from the mounting portion 24a.
The projections 22, 22
The mounting portion 24a is constructed and fixed to the arm portion 24b,
The auxiliary pouring tube 23 is held between the tubes 24b and 24b. In this way, attach the pouring auxiliary pipe 23 to the holder 24.
By holding it in place, the auxiliary pouring pipe 23 can be attached with a single touch.

Further, on the outer edge of the upper end opening 19 of the gutter groove 15, a locking protrusion 26 is provided that protrudes from the upper end of the lid body 25.
A hole 27 into which the lid body 2 is inserted is formed on the inner surface of the groove at the lower end opening 20 of the gutter groove 15.
5. A protrusion 29 that locks the claw piece 28 protruding from the lower end.
is formed.

The auxiliary pouring pipe 23 has a substantially L-shaped pipe main body 23.
a, and a wrapper-shaped seal tube 23b made of an elastic material such as rubber and connected to the upper end of the tube body 23a.

This pouring auxiliary pipe 23 is arranged so that the seal pipe 23b is brought into contact with the periphery of the upper end opening 19 of the gutter groove 15, while the pipe main body 2
3a is pressed into contact with the bottom surface of the horizontal groove portion 15b of the gutter groove 15, thereby being removably disposed within the gutter groove 15. At the same time, the tube body 23a is attached to the holder 24.
It is held by the arms 24b, 24b to prevent swinging in the front, back, left and right directions. In other words, the auxiliary pouring pipe 23 is connected to the pipe cover 14 with an appropriate gap.
It is protected from direct impact from external forces. In addition,
In the case of this embodiment, the upper side of the auxiliary pouring pipe 23 is a sealed tube 23b, and the upper end of the sealing tube 23b is brought into contact with the lower surface of the upper end opening periphery of the pipe cover 14. is merely supported by the holder 24, so that a gap may occur between the upper end surface of the seal tube 23b and the lower surface of the pipe cover 14.

By configuring as described above, the pouring auxiliary pipe 2
In the upper end opening 32 of 3, the spout 12 of the liquid spouting pipe 11 is exposed through an annular gap, and the liquid spouting pipe 11 and the auxiliary spouting pipe 23 are exposed to the atmosphere at this position. It is supposed to be able to communicate with the In other words, liquid pouring pipe 1
1 and the auxiliary pouring pipe 23 is located below the upper surface of the shoulder member 5 and above the liquid supply port 9 of the medium container 2. Therefore,
It becomes possible to make the height of the liquid pouring pipe 11 as small as possible, and as a result, the height of the portion above the shoulder member 5 can be made small, contributing to making the liquid container more compact. In addition, the opening position of the spout 12 of the liquid spouting pipe 11 is
The siphon phenomenon is prevented by placing the liquid supply port 9 above the liquid supply port 9. In addition, the pouring auxiliary pipe 23
The lower end opening 33 is located slightly lower than the lower end opening 20 of the gutter groove 15.

Further, the lid body 25 is formed into a substantially L-shape that is the same as the shape of the front opening 41 of the gutter groove 15, and an upwardly directed protrusion 26 is provided at the upper end of the lid body 25.
Further, an inwardly facing claw piece 28 is formed at the lower end thereof, and the side wall 3 of the gutter groove 15 is formed on the inner surface thereof.
0,30 Protrusions 31, 3 that are pressure-fitted to the inner surface
1 is formed.

Thus, this lid body 25 has a protrusion 26 formed in a hole 27 formed on the outer edge of the upper end opening 19 of the gutter groove 15.
After engaging with the projection 29 of the gutter groove 15, the projections 31, 31 are press-fitted to the inner surfaces of the side walls 30, 30 of the gutter groove 15, and the claw piece 28 is engaged with the protrusion 29 of the gutter groove 15. The front opening 41 of the gutter groove 15 is removably covered.

Next, the operation of the illustrated liquid container will be explained.

When pressurized air is forced into the inner container 2 from the air pump 6 through the inner stopper 8 by pressing the presser lid 7, the internal solution W is drawn into the liquid pumping tube 10 and the liquid pouring tube 10 by the pressurized air. Passing through the pipe 11, the auxiliary pouring pipe 2
3 and is poured into a liquid receiving container 21 such as a pot. In this case, the lower end opening 33 of the pouring auxiliary pipe 23, which serves as the external injection port for the liquid content W, opens at a position close to the liquid receiving container 21 placed on the floor surface on which the liquid container is placed. , the liquid can be poured while the liquid receiving container 21 is placed on the floor.

Moreover, when the content liquid W decreases, the liquid pouring pipe 11
A so-called splash phenomenon occurs in which gas and liquid are mixed and ejected from the spout 12 at the tip. Because we are approaching
A splash phenomenon no longer occurs at the lower end opening 33 of the auxiliary pouring pipe 23, which serves as a substantial liquid inlet. Note that gas and liquid may be ejected in a mixed state from the spout 12 of the liquid spout pipe 11, but the liquid spout pipe 11 and the spout auxiliary pipe 23 are connected to the pipe cover 14.
Since the inside is connected to the inside, splashing of liquid to the outside is prevented.

Furthermore, since the communication position between the liquid spouting pipe 11 and the auxiliary spouting pipe 23 is set above the liquid supply port 9 of the medium container 2, the siphon phenomenon during liquid pouring is avoided.

Embodiment 2 A second embodiment of the invention is shown in FIGS. 4 and 5. In this case, the pipe cover 14 holding the auxiliary pouring pipe 23 is attached to and detachable from the mounting portion 14a attached to the side surface of the main body case 1 with screws 36, and the auxiliary spouting pipe 23 is
3. That is, the auxiliary pouring pipe 23 is removably held in a holder 24 that is integrally provided on the mounting part 14a, and the screws 3 are attached to the upper and lower positions of the mounting part 14a.
6 and 36, an elastic support 37,
37, a lid portion 14b having a U-shaped cross section is detachably attached by force fitting. Furthermore,
In the case of this embodiment, an annular recess 38 is formed on the outer periphery of the pouring auxiliary pipe 23 corresponding to the holder 24, and the arm portions 24b, 24b of the holder 24 are formed in the annular recess 38.
By engaging these, it is possible to prevent the dispensing auxiliary pipe 23 from moving in the front, rear, right and left directions.

Note that the holder 24 is provided protruding from the inner surface of the lid part 14b, and is detachably attached to the mounting part 14a attached to the main body case 1 side with the auxiliary pouring pipe 23 attached to the lid part 14b side. You can also do it like this.

The other configurations and operations are the same as those of the first embodiment, so their explanation will be omitted.

(Effect of the invention) The liquid container of the present invention has the following effects.

(1) Since the spout 12 of the liquid spouting pipe 11 is opened at a position below the dish-shaped surface of the shoulder member 5 and at a position above the liquid supply port 9 of the medium container 2, the liquid spouting pipe The height of the liquid outlet pipe 11 can be made as low as possible without causing siphon action from the liquid outlet pipe spout 12, thereby making it possible to make the liquid container more compact.

(2) Since the upper end opening 32 of the auxiliary pouring pipe 23 is communicated with the spout 12 of the liquid pouring tube 11 with a gap, the splash phenomenon that occurs when the content becomes low can be prevented from pouring out. It is no longer generated from the lower end opening of the auxiliary pipe 23.

(3) Since the auxiliary pouring tube 23 is fixed with an appropriate fixing means with its upper end opening 32 simply facing the lower surface of the shoulder member 5, the auxiliary pouring tube 23 can be screwed together, for example. The assembly work is easier than when it is fixed.

(4) As mentioned in (3) above, the upper end opening 3 of the auxiliary pouring pipe 23
2 simply facing the lower surface of the shoulder member 5, there may be a gap between the upper end opening 32 and the lower surface of the shoulder member 5, and in that case, there may be a gap between the upper end opening 32 and the lower surface of the shoulder member 5. The water droplets of the generated splash pass through the above-mentioned gap to the spouting auxiliary pipe 2.
3. Although it may leak outside, the auxiliary pouring pipe 23
Since the outside of the shoulder member 5 is covered with a pipe cover 14 connected to the lower surface of the shoulder member 5, the above-mentioned interval
Water droplets leaking out of the pouring auxiliary pipe 23 through the pipe cover 14 are carded and are prevented from scattering outside the liquid container.
