Description

[Detailed description of the invention] (Field of industrial application) The present invention is a pump capable of discharging liquid in an inner container to the outside through a series of liquid dispensing passages using pressurized air from a pump device. Regarding pouring type liquid containers, in more detail, a stopper for opening and closing the liquid supply port of the liquid container body is integrally provided on the bottom surface of the lid provided at the top of the liquid container body, and the stopper can be opened and closed simply by opening and closing the lid. This invention relates to a pump-type liquid container that can be opened and closed.

(Prior art) As a conventional pump injection type liquid container of this type,
The one shown in FIG. 4 (Utility Model Application Publication No. 12343/1983) is known. In this known pump injection type liquid container, the liquid container main body 1 is provided on the bottom surface of the lid 121.
A stopper 125 that opens and closes the liquid supply port 108 of 01 is integrally attached, and the stopper 125 is simultaneously opened and closed by the single rotation opening and closing operation of the cover 121, and when replenishing liquid into the inner container 106 or This makes it possible to omit the work of individually attaching and detaching the stopper 125 when draining residual liquid. The inside of the stopper 125 is filled with a heat insulating material 128 made of a foamed resin molded product in order to enhance the heat retention effect of the liquid inside the inner container 106 when the stopper is closed. In addition, the plug body 125 is
As the thickness (height) increases, the amount of heat insulating material 128 filled inside the inner container 1 can be increased.
The heat retention effect of the liquid in 06 can be improved.

In addition, in the known pump injection type liquid container shown in FIG. A water stop valve 140 is provided to prevent liquid from flowing out through the liquid pouring passage 104 to the outside. This water stop valve 140 has a water stop valve 1 installed in a part of the liquid pouring passage 104.
A large-capacity valve accommodating part 141 capable of accommodating 40 is formed and accommodated in the valve accommodating part 141,
In this known example, the valve accommodating portion 141 is connected to the inner container 10.
It is provided in the liquid supply port 108 portion above the upper opening 111 of No.6. In addition, the plug body 125 is such that when the lid body 121 is opened and closed, the plug body 125 is attached to the valve housing portion 141.
It is necessary to make the shape and thickness (depth) so that it does not collide with other objects.

By the way, in the known pump injection type liquid container shown in FIG. 4, a large valve accommodating portion 141 is provided at the liquid supply port 108, and is the same as the stopper 125 that opens and closes the liquid supply port 108. Since the plug body 125 is located at a high height, it is necessary to reduce the thickness of the plug body 125 to the extent that the plug body 125 does not collide with the valve accommodating portion 141 when the lid body is opened and closed. There was a problem in that as the thickness of the heat insulating material 128 became thinner, the heat retaining effect of the liquid in the inner container 106 became smaller. Note that the valve accommodating portion 141 can also be provided in the sideways liquid spouting pipe 132 portion of the series of liquid pouring passages 104;
If it is provided in the liquid spout pipe 132 part, there will be no problem of the stopper colliding with the valve accommodating part when the lid is opened and closed. This method has the disadvantage that a space is required for installing the liquid container, which increases the height of the entire liquid container. Furthermore, if the valve accommodating part 141 is provided in the middle part of the liquid pumping tube 131 inserted into the inner container 106, the stopper will not collide with the valve accommodating part when opening and closing the lid. If the valve body 141 is installed deep inside the inner container 106, the valve body inside the valve accommodating portion may become immersed in the liquid, and the normal water stop action (valve closing action) may not occur when the liquid container falls over. be.

(Purpose of the invention) In view of the above-mentioned problems of the known pump-filling type liquid containers, the present invention provides a stopper integrally on the lower surface of the lid body, and a series of liquid pouring passages to prevent the liquid container from falling over. In a pump injection type liquid container equipped with a water valve, the thickness of the stopper (insertion depth) can be increased, thereby improving the heat retention effect of the liquid in the inner container, and the stopper can be Even if the thickness of the liquid container can be increased, the water stop valve accommodating part provided in the middle of the liquid dispensing passage prevents the liquid container from becoming too large, and also prevents the liquid dispensing passage from being blocked when the liquid container falls over. The purpose of this is to ensure that the operation of the water stop valve is not obstructed.

(Means for Achieving the Object) The present invention provides a stopper for opening and closing the liquid supply port of the liquid container main body, which is integrally provided on the lower surface of the lid installed on the upper part of the liquid container main body, and further provides a liquid container with a pump device. The liquid in the inner container of the main body can be poured out to the outside through a liquid pouring passage provided on the liquid container body side, and a stop is provided in the middle of the liquid pouring passage to block the liquid pouring passage when the liquid container falls. In a pump-injection type liquid container provided with a valve accommodating portion containing a water valve, the valve accommodating portion is inserted into the upper opening of the inner container and located at a position higher than the full liquid height of the liquid contained in the inner container. Moreover, it is installed at a position close to the front inner surface of the inner container, and
It is characterized in that the plug body is inserted to a depth that reaches the upper opening of the inner container.

(Function) According to the pump-filling type liquid container of the present invention, the valve accommodating part containing the water stop valve that blocks the liquid pouring passage when the liquid container falls is installed by being inserted into the upper opening of the inner container. Therefore, the valve accommodating part can be located below the liquid supply port, and since the valve accommodating part is installed at a position higher than the full liquid level of the liquid stored in the inner container, the valve accommodating part can be located below the liquid supply port. Since the valve is not immersed in the liquid, the water-stopping effect is not hindered when the liquid container falls over, and since the valve accommodating portion is located close to the front inner surface of the inner container, the inner container Even when a valve accommodating portion is provided in the upper opening, a sufficient opening area for liquid supply can be ensured. Furthermore, since the plug integrally provided on the lower surface of the lid is inserted to a depth that reaches the upper opening of the inner container, the thickness of the heat insulating material filled inside the plug can be increased. Furthermore, even if the lid body is inserted to a depth that reaches the upper opening of the inner container, since the valve accommodating portion is provided at a low position (inside the inner container), the stopper body can be opened and closed with a single rotation along with the lid body. At this time, the valve accommodating portion does not become an obstacle to the movement of the plug.

(Example) Some embodiments of the present invention will be explained with reference to Figs. 1 to 3. Figs. A liquid container is shown.

The pump injection type liquid container of the first embodiment shown in FIG. A liquid container main body 1 is fixed in place, a series of liquid dispensing passages 4 communicating the inside and outside of the inner container 6, a bellows-type pump device 9 is housed in a lid 21, and a liquid is disposed on the lower surface of the lid 21. Liquid supply port 8 of container body 1
The lid unit 2 includes a lid unit 2 integrally provided with a stopper 25 for opening and closing.

The lid unit 2 is pivotally attached to the upper rear side of the liquid container body 1 by a hinge pin 13. Further, in this first embodiment, a notch 15 for attaching and detaching the hinge pin is formed in the hinge pin receiving member 14 on the side of the liquid container body 1, so that the lid unit 2 can be removed from the liquid container body 1 as necessary. We are making it possible to do so.

The shoulder member 7 is formed into a dish shape, and has a hole 71 approximately in the center thereof that communicates with the upper opening 11 of the inner container 6.
is formed.

The liquid pouring passage 4 includes a vertical liquid pumping tube 31 inserted into the inner container 6 and a horizontal liquid pouring tube 3.
2, and an auxiliary spouting tube 33 located below the tip of the liquid spouting tube 32.

The liquid pumping pipe 31 and the liquid pouring pipe 32 are
In the embodiment, each annular tube holder member 30
is fixed. The liquid pumping tube 31 and the liquid pouring tube 32 are communicated with each other via a liquid passage 34 within the tube holder member 30.

The tube holder member 30 has an inner and outer double wall structure except for the member forming the liquid passage 34, and a heat insulating material 38 made of foamed resin is filled between the inner and outer double walls.

This tube holder member 30 is adapted to be detachably attached to the upper part of the mouth of the hole 71 of the shoulder member 7 with the liquid pumping tube 31 and the liquid pouring tube 32 attached. When the tube holder member 30 is installed, the annular packing 35 provided on the lower surface of the tube holder member 30 airtightly closes the upper surface of the opening of the hole 71 of the shoulder member 7.

Further, in this first embodiment, a liquid supply port 8 for injecting liquid into the inner container 6 is formed in the tube holder member 30. That is, the tube holder member 30 has an opening (liquid supply port 8) with a relatively large opening area formed in the center thereof, and liquid is supplied from the opening 8 into the inner container 6 while the tube holder member 30 is attached. It has become possible to replenish the supply of The tube holder member 30 is pulled out from the hole 71 of the shoulder member 7 when draining the residual liquid in the inner container 6 and cleaning the liquid pouring passage 4 and the inner container 6.

A water stop valve 40 is provided in the liquid passage 34 of the tube holder member 30 to prevent the liquid in the inner container 6 from flowing out through the liquid pouring passage 4 when the liquid container is turned over. The water stop valve 40 is provided in a valve housing portion 4 having a larger diameter than the pipe portion of the liquid passage 34.
The valve accommodating portion 41 is formed in the liquid passage 34 located in the inner container 6 when the tube holder member 30 is attached. That is, in this first embodiment, the valve accommodating portion 41 is formed in the inner container 6 at a position higher than the full liquid height L of the liquid contained in the inner container and in a position close to the front inner surface 6a of the inner container.
When the valve accommodating portion 41 is installed as described above, the installation height of the valve accommodating portion 41 can be lowered below the liquid supply port 8, and the valve accommodating portion 41 will not be submerged in the liquid in the inner container 6, causing the water stop valve 40 to fail to stop water supply when the liquid container is overturned. Furthermore, even if the accommodating portion 41 is located at approximately the same height as the upper opening 11 of the inner container, a sufficient opening area for liquid supply is ensured. Incidentally, the inside of the upper opening 11 of the inner container 6 is normally a space that is not used, but by installing the valve accommodating portion 41 in the upper opening 11 of the inner container 6 in this way,
By installing the above, the inside of the upper opening 11 of the inner container can be effectively utilized.

A plug body 25 for opening and closing the liquid supply port 8 formed in the tube holder member 30 is integrally attached to the lower surface of the lid body 21 (the lower surface of the bottom plate 9a of the pump device 9) by force fitting. An annular packing 26 is provided on the outer periphery of the stopper 25, which comes into contact with the upper surface of the lip of the liquid supply port 8 of the tube holder member 30 when the lid is closed. Moreover, this plug body 25 has a lower end 2 when the lid is closed.
The inner container 6 is formed to have a thickness such that the inner container 5a can be inserted to a depth that reaches the upper opening 11 of the inner container 6. In this liquid container, the installation height of the valve accommodating portion 41 is lowered to the height located inside the inner container 6, and the thickness of the stopper 25 (the depth of the lower end 25a of the stopper) is reduced as described above. Even if it is enlarged to reach the upper opening 11 of the inner container, the stopper 25 will not collide with the valve accommodating portion 41 when opening and closing the lid. Further, the inside of the plug body 25 is filled with a heat insulating material 8 made of foamed resin. In addition, by increasing the thickness of the plug body 25 as described above, the heat insulating material 28 filled inside the plug body 25 can be increased.
The thickness of the plug body 25 can also be increased, thereby improving the heat retention ability at the plug body 25 portion.

An air blowing passage 27 is formed in the stopper 25 to communicate the pump device 9 and the inner container 6.

An annular heat insulating material 78 made of foamed resin is provided on the outside of the annular wall 72 constituting the hole 71 of the shoulder member 7, and the annular heat insulating material 78 and the plug body 25
The heat in the liquid in the inner container 6 is prevented from being released to the outside from the upper opening 11 of the inner container 6 by the heat insulating material 28 inside the tube holder member 30 and the heat insulating material 38 between the double walls of the tube holder member 30. I'm trying to prevent it.

In FIG. 1, reference numeral 16 is a lid locking member provided on the lid unit 2 side.

In the pump injection type liquid container of this first embodiment,
When injecting liquid into the inner container 6, open the lid unit 2 (with the tube holder member 30 attached to the hole 71 of the shoulder member 7) and inject the liquid from the liquid supply port 8 of the tube holder member 30. good. In addition, when the lid unit 2 is in the closed state, the area near the upper opening 11 of the inner container 6, which is relatively easy to radiate heat, is
8. Heat can be effectively kept by the heat insulating material 38 in the tube holder member 30 portion and the insulating material 78 on the outer surface of the annular wall of the shoulder member 7, and by increasing the thickness of the plug body 25 portion, the heat insulation can be filled inside. The material 28 can also be made thicker, thereby improving the heat retention effect. When the pump push plate 10 provided at the center of the upper part of the lid body 21 is pressed, pressurized air from the pump device 9 is blown into the inner container 6, and the liquid in the inner container 6 is caused to flow through the pressurized air. The liquid is poured out from the lower end of the auxiliary pouring pipe 33 through the liquid pouring passage 4 . Furthermore, even if the liquid container is accidentally overturned, the water stop valve 40 closes the liquid passage 34 to prevent the liquid in the inner container 6 from pouring out through the series of liquid pouring passages 4. I'm starting to do that.

In the pump-filling type liquid container of the second embodiment shown in FIG. 2, the tube holder member 30 is formed into a ring shape with a single wall. The tube holder member 30 is fixed to the lower surface of the mouth edge of the hole 71 of the shoulder member 7 via an annular packing 36. Further, in this second embodiment, the liquid pumping pipe 31 and the liquid pouring pipe 32 of the liquid pouring passage 4 can be connected to each other in a separable manner. That is, the valve accommodating portion 4 is provided in the upper part of the liquid pumping pipe 31.
1 is attached, and furthermore, the upper part of the valve accommodating part 41 is used as a horizontal insertion part 43, while a fitting recess 37 into which the insertion part 43 can be fitted is formed in a part (front part) of the tube holder member 30. Then, insert the insertion part 4
3 is removably fitted into the fitting recess 37, and the liquid spouting pipe 3 is removably fitted into the fitting recess 37.
2 is fixed in the fitting recess 37 in a communicating state. Then, the insertion portion 43 of the valve housing portion 41
By removing it from the fitting recess 37 of the tube holder member 30, the liquid pumping tube 31 and the valve accommodating portion 41 can be cleaned independently. Moreover, the tube holder member 30
A heat insulating material 38 is filled between the shoulder member 7 and the inner annular wall 72 of the shoulder member 7, except for the area where the fitting recess 37 is formed.

Further, in this second embodiment, the hole 71 of the shoulder member 7 serves as the liquid supply port 8, and the liquid supply port 8 is closed by the stopper 25 when the lid is closed. The lid locking member 16 is provided on the side of the liquid container body 1, and its claw portion 18 locks the claw receiving portion 22 on the lid 21 side when the lid is closed. Further, on the upper rear side of the liquid container body 1 (shoulder member 7), there is a pusher 51 which is biased upward by a spring 52.
is provided to be able to move up and down. This pusher 51
When the lid is closed, the lower surface of the lid unit 2 on the pivot side is always urged upward, and the lid locking member 1
Press the operating part 17 of 6 to move the claw part 18 to the claw receiver part 22.
When the cover unit 2 is removed from the cover, the cover unit 2 is automatically raised by a certain height (for example, about 5 mm) around the hinge pin 13, as shown by the chain line 2'. In addition, if the lid unit 2 is made to rise by a slight height by operating the lid locking member 16 once during the lid lock release operation in this way, the lid locking member 2 will be lifted up by a slight height after the lid locking member is pressed. Even if you take your finger off of the button, the lid unit 2 will not be relocked. This prevents the trouble of having to unlock the lid unit 2 again due to the lid unit 2 being inadvertently relocked when the lid unit is opened. can be resolved.

The third embodiment shown in FIG. 3 shows a modification of FIG. 2. In this third embodiment, the liquid pumping pipe 3
A cylindrical wall 5 having a size inscribed in the inner surface of the tube holder member 30 is connected to the valve housing portion 41 connected to the upper part of the tube holder member 30.
4, and the cylindrical wall 54 is attached to the tube holder member 30.
By fitting into the inner surface, the liquid passage outlet 41a in the valve accommodating portion 41 and the liquid passage 34 formed in the tube holder member 30 are airtightly communicated via the packing 55.

(Effect of the invention) The pump liquid container of the invention has a stopper body 2 for opening and closing the liquid supply port 8, which is integrally provided on the lower surface of the lid body 21.
5 is inserted to a depth that reaches the upper opening 11 of the inner container 6 when the lid is closed, the thickness of the heat insulating material 28 filled in the plug body 25 can be increased, and the plug body 2
This has the effect of improving the heat retention effect in the 5 parts.

Further, according to the present invention, the valve accommodating portion 41 containing the water stop valve 40 (which has a large diameter because the water stop valve is accommodated) that shuts off the inside of the liquid pouring passage 4 when the liquid container falls is inserted into the inner container 6. Since the valve accommodating portion 41 is positioned below the liquid supply port 8, the stopper 25 is inserted into the upper opening 11 of the inner container 6 until it reaches the upper opening 11 of the inner container 6. Even if it is made thicker (deeper), the valve accommodating portion 41 will not become an obstacle to the movement of the plug 25 when the lid is opened and closed, and the valve accommodating portion 41 will not hinder the movement of the plug 25.
Even if the plug body 25 is of a type that can be opened and closed together with the lid body 21, the plug body 25 is of a type that can be opened and closed together with the lid body 21.
This has the effect of making it possible to increase the thickness of the film. Furthermore, since the valve accommodating portion 41 is installed at a position higher than the full liquid height L of the liquid contained in the inner container 6, the valve accommodating portion 41 is provided in the inner container 6. Also, the valve accommodating portion 41 is not immersed in the liquid, and therefore, when the liquid container falls over, the water shutoff operation of the water stop valve 40 in the valve accommodating portion 41 is not hindered and the water can be shut off reliably. Since the valve accommodating portion 41 is installed in a position close to the front inner surface 6a of the inner container 6, even if the valve accommodating portion 4 is located within the upper opening 11 of the inner container, the valve accommodating portion 41 is located close to the front inner surface 6a of the inner container 6. The opening area is secured.
