Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a pump injection type liquid container, and more specifically, an air pump is driven by pushing down a pump push plate provided on a lid. The present invention relates to a pump injection type liquid container.

(Prior Art) In a conventional pump injection type liquid container of this type, a pump push plate for operating an air pump provided in a lid body is an upper surface of the pump push plate when the pump is at rest (pump extension state). Installed so that it projects above the upper surface of the lid (for example, Japanese Utility Model Laid-Open No. 55-107841), or similarly when the pump is stopped, the upper surface of the pump push plate is substantially flush with the upper surface of the lid. There is one installed in such a manner (for example, Japanese Utility Model Laid-Open No. 61-180648). Further, in these pump push plate operation type pump injection type liquid containers, generally, a push plate lock member for restricting downward movement of the pump push plate when not in use is provided.

(Problems to be solved by the invention) However, in the conventional pump injection type liquid container in which the pump push plate is installed so as to project further upward from the upper surface of the lid when the pump is stopped, the pump push plate is operated when the pump is operated. Although there is an advantage that it is easy to perform the pressing operation of the liquid container, the height of the entire liquid container is not large by the height that the pump pressing plate projects above the upper surface of the lid when the pump is stopped, and the design is not preferable. was there.

Further, in a conventional pump injection type liquid container in which the pump push plate is installed so as to be substantially flush with the upper surface of the lid when the pump is stopped, the pump push plate does not project upward from the upper surface of the lid, Although the overall height of the container can be kept low and the design is also good, the hand must be on the top surface of the lid (upper opening of the pump push plate sliding hole) when operating the pump (when pushing down the pump push plate). There is a problem that the pump stroke becomes difficult because the pump is difficult to operate due to contact with the edge).

In view of the above problems of the conventional pump injection type liquid container, the present invention utilizes the pressing plate lock member to position the pump pressing plate substantially flush with the top surface of the lid when not in use. The pump injection type that keeps the height of the pump low and the design is good, and that the pump push plate can be protruded upward from the lid upper surface during use (when pouring liquid) to facilitate pump operation. It is intended to provide a liquid container.

(Means for Solving the Problems) According to the present invention, a lid body containing an air pump inside is placed on an upper portion of a liquid container body, and a pump push plate provided on the upper portion of the lid body is operated downward. The air pump can be compressed after the intake valve provided on the upper plate of the air pump is closed by the pump, and the push plate lock member for restricting the downward movement of the pump push plate is pushed in the lid body. In a pump injection type liquid container installed so as to be movable between two positions, a plate lock release position and a pump push plate lock position,
The pump push plate is configured such that, when the push plate lock member is positioned at the pump push plate lock release position, the upper surface of the pump push plate is projected upward from the upper surface of the lid body by the extension action of the air pump. On the other hand, when the push plate lock member is positioned at the pump push plate lock position between the push plate lock member and the pump push plate, the pump push plate is placed on the upper surface of the pump push plate. Is provided with a pump push plate pushing cam mechanism that can forcibly push down to a position where is substantially flush with the upper surface of the lid body, and further, between the push plate lock member and the pump upper plate, When the plate lock member is operated from the pump push plate lock release position to the pump push plate lock position side, the pump upper plate is pushed down before the suction valve is closed by the downward movement of the pump push plate, and the inside of the air pump is pushed. It is characterized in that is provided with the pump upper pressing cam mechanism capable of preventing from being compressed.

(Operation) According to the pump injection type liquid container of the present invention, when the push plate lock member is located at the push plate lock release position, the pump push plate can be moved up and down. Due to the extension action of the air pump, the upper surface of the pump push plate is automatically made to project further upward from the upper surface of the lid body. Further, when the push plate lock member is positioned at the pump push plate lock position, the vertical movement operation of the pump push plate becomes impossible, and the pump push plate lowering cam mechanism causes the upper face of the pump push plate to be almost the top face of the lid body. It works by forcibly pushing down to the same level. Furthermore, when the push plate lock member is positioned at the pump push plate lock position,
The cam mechanism for pushing down the pump upper plate forcibly pushes down the upper plate of the pump to keep the intake valve open, so the pump pushing plate is moved downward by the locking operation of the pushing plate locking member. However, the air in the air pump is not compressed thereby.

(Effects of the Invention) According to the pump injection type liquid container of the present invention, the upper surface of the pump pressing plate is automatically moved to the upper surface of the lid by the pump extending action when the pressing plate locking member is positioned at the pump pressing plate unlocking position. Since it protrudes further upward, there is an effect that the pressing operation of the pump pressing plate can be easily performed during the liquid pouring operation (when the pump pressing plate is pressed) and the pressing stroke of the pump pressing plate can be made large. Even if the upper surface of the pump push plate is positioned above the upper surface of the lid during the liquid pouring operation, the pump push plate can be pushed by simply moving the push plate lock member to the pump push plate lock position. Since the upper surface of the plate can be located almost on the same plane as the upper surface of the lid, the height of the entire liquid container can be kept low when not in use (it can be made compact) and the design can be improved. There is.

The push plate lock member 5 can be rotated within a range of (°).

At a position near the lower end of the cylinder portion 51 of the push plate lock member 5, a total of three lock receiving portions 54, 54, 54 for holding the respective projections 41, 41, 41 of the pump push plate 4 in a vertically immovable state. Is provided. Each of the lock receiving portions 54, 54, 54 is formed in a lateral groove shape, and in this embodiment, when the push plate lock member 5 is rotated to the right, each of the lock receiving portions 54, 54, 54 becomes a protrusion 41. , 41, 41 are fitted to lock the pump push plate 4, and conversely, when the push plate lock member 5 is rotated counterclockwise, the respective lock receiving portions 54, 54, 54 are separated from the respective projections 41, 41, 41. The pump push plate 4 is unlocked.

Between the push plate lock member 5 and the pump push plate 4, when the push plate lock member 5 is rotated from the lock release position side to the lock position side (left rotation operation), the pump push plate 4 is extended by the pump. The cam mechanism 6 for pushing down the pump push plate is provided for forcibly moving downward against the urging force of the spring 34. In this embodiment, the pump push plate pressing cam mechanism 6 has a total of three cams 61, 61, 61 formed by cutting out a part of the cylindrical portion 51 of the push plate lock member 5 and the cam surface of the cam 61. It is composed of the above-mentioned projections 41, 41, 41 of the pump push plate 4 which can be moved up and down along 62. The cam surface 62 of each cam 61, 61, 61 rises and tilts in the right rotation direction, and the lower end portion 62a of the cam surface 62 is
Is continuous with the entrance 54a of the lock receiving portion 54. Immediately below the upper end portion 62b of the cam surface 62 is cut out until it reaches the lower end of the push plate lock member cylinder portion 51, and the projection 41 on the pump push plate 4 side freely moves up and down with respect to the push plate lock member 5. I'm supposed to get it. Then, in the state where the push plate lock member 5 is positioned at the lock position, the projection 41 on the pump push plate 4 side has the locking receiving portion on the push plate lock member 5 side as shown by the solid line in FIG.
The whole of the pump push plate 4 is held in an immovable state by being fitted into the inside of the pump push plate 54, and the upper surface 4a of the pump push plate 4 is the upper surface 2a of the lid 2.
It is set to be almost flush with. Further, if the push plate lock member 5 is rotated in the unlocking direction (clockwise rotation direction) from the lock position by operating the operation knob 53, after the projection 41 disengages from the lock receiving portion 54, the pump push plate 4 The protrusion 41 is moved upward along the cam surface 62 by being urged upward by the pump extension spring 34, and when the push plate lock member 5 is rotated to the unlocked position, the cam surface is rotated. 62 moves to the position shown by the chain line 62 'in FIG. 3, at which time the entire pump pushing plate 4 projects upward as shown by the chain line 4', and the upper surface 4a 'of the pump pushing plate 4 is covered by the lid 2. It projects upward by a height H from the upper surface 2a. In addition, when the operating knob 53 is operated to rotate the push plate lock member 5 from the unlocked position to the lock position direction (counterclockwise rotation direction),
The cam surface 62 moves from the position of the chain line 62 'to the position shown by the solid line, at which time each cam surface 62, 62, 62 simultaneously presses each projection 41, 41, 41 of the pump pressing plate 4 downward. Then, the pump push plate 4 is forcibly pushed down against the urging force of the pump extension spring 34, and when the push plate lock member 5 is rotated to the lock position, the protrusions 41, 41, 41 are automatically set. So that the pump push plate 4 is locked in the lower position (substantially at the same height as the pump push plate upper surface 4a and the lid upper surface 2a) by being fitted into the respective lock receiving portions 54, 54, 54. ing.

Further, in this pump injection type liquid container, when the push plate lock member 5 is locked as described above, the pump push plate 4 moves downward and the air in the air pump 3 is inadvertently compressed. In order to prevent this, a pump upper plate lowering cam mechanism 7 is provided between the push plate lock member 5 and the pump upper plate 31. That is, when pumping the liquid, it is necessary to compress the air pump 3 after closing the suction valve 37 by pressing the pump pressing plate 4, but when the pressing plate locking member 5 is locked, the pump pressing plate 4 is lowered. It is necessary to prevent the intake valve 37 from closing even when it moves, and therefore, the pump upper plate pressing cam mechanism 7 is provided and immediately before the pump pressing plate 4 moves down or below the pump pressing plate 4. Simultaneously with the dynamic operation, the pump upper plate 31 is pushed down so that the suction valve 37 does not block the suction port 35. The pump upper plate pressing cam mechanism 7 includes a pressing plate locking member 5
The first cams (there are three locations in total in the circumferential direction) 71, 71, 71 provided on the outer surface of the tubular portion 51 and the second cam (also in the circumferential direction) provided on the upper surface of the pump upper plate 31. There are 3 places in total) 74,74,
It consists of 74 and. The first cam 71 on the side of the push plate lock member 5 and the second cam 74 on the side of the pump upper plate 31 are in the lock position of the push plate lock member 5 (the position shown by the solid line in FIG. 3).
When the cams 71 and 74 are in the position, the cam tops 72a and 75a of the cams 71 and 74 abut each other to act to forcibly move the pump upper plate 31 downward, and conversely, the push plate lock member 5 releases the lock position ( When the cams 71 and 74 are close to each other when the cams 71 and 74 are close to each other (reference numerals 71 'and 74'), the push plate lock member 5 is moved from the unlocked position to the locked position. Operate in the direction (counterclockwise operation)
When the pump push plate 4 is moved downward, the cam surfaces 72 and 75 of the cams 71 and 74 abut against each other before the intake valve 37 is closed, so that the pump upper plate 31 is pushed down. . Therefore, when the push plate lock member 5 is operated from the unlocked position toward the lock position, the suction valve 37 is not closed even if the pump push plate 4 is moved downward, and the inside of the air pump 3 is It will not be carelessly compressed.

The liquid pouring passage 10 is connected to the liquid pumping pipe 18 inserted into the inner container 14, the liquid pouring pipe 19 installed laterally outside the inner container 14, and below the liquid pouring pipe 19. And a spout tube 20 that is The upper end side of the liquid pumping pipe 18 and the proximal end side of the liquid spouting pipe 19 are continuous through a hole 17 formed in the tubular member 16.

The liquid volume display device 8 is a liquid volume display tube 81 composed of a vertically long transparent tube.
And the lower end of the liquid volume display tube 81 and the lower opening 14c of the inner container 14.
A lower connection pipe 82 for connecting the upper end portion of the liquid amount display pipe 81 and the upper opening 14b of the inner container 14 (in this embodiment, the cylindrical member 16
And an upper connection pipe 83 for connecting with (inside). The liquid amount display tube 81 is installed in a gap S provided between the rear surface of the outer case 11 on the front side and the outer surface of the inner container 14. Since the inner container 14 is installed at a position eccentric to the rear side of the outer case 11 as described above, it is possible to increase the inner diameter of the outer case 11 or decrease the body diameter of the inner container 14. Without this, a gap S for installing the liquid quantity display tube 18 can be formed between the rear surface of the outer case 11 on the front side and the outer surface of the inner container 14. In FIG. 1, reference numeral 84 is a viewing window of the liquid amount display tube 81.

In the illustrated pump pouring type liquid container, when the push plate lock member 5 is positioned at the unlocked position, the pump push plate 4 becomes free in the vertical direction, and the pump push plate 4 is pressed by the urging force of the pump extension spring 34. Is pushed up to the upper moving position shown in FIG. 4 via the suction valve 37. In the state shown in FIG. 4, the upper surface 4a of the pump push plate 4 is projected above the upper surface 2a of the lid body 2 by a considerable height (reference numeral H in FIG. 3), and the pump push plate is pushed during the pump operation. The pressing operation of the plate 4 becomes easy and the pump stroke can be made large (in FIG. 4, the pump upper plate 31 can be compressed from the position shown by the solid line to the position shown by the chain line 31 '). If the pump push plate 4 is pressed while the push plate lock member 5 is unlocked, the suction valve 37
After the valve is closed, the air pump 3 is compressed, and the pressurized air is blown into the inner container 14 so that the liquid in the inner container 14 can be discharged to the outside through the series of liquid discharge passages 10. Further, when the push plate lock member 5 is operated from the unlocked position to the lock position, the pump push plate pushing cam mechanism 6 pushes down the upper surface 4a of the pump push plate 4 to a position substantially flush with the upper surface 2a of the lid 2. In this state, the pump push plate 4 is locked. In this state, the pump push plate 4 is operated when the pump is operated.
Even if the lid is made to project above the lid upper surface 2a, the height of the liquid container as a whole is lowered, and it is compact and has a good design.
