Description

[Detailed description of the invention] (Field of industrial application) This invention uses pressurized air from an air pump to inject the liquid in the inner container contained in the liquid container body to the outside through a series of liquid pouring passages. This invention relates to a pump-type liquid container that can be dispensed.

(Prior Art) FIG. 7 shows a conventional general pump-injection type liquid container. Lid body 1 housing pump 109
20 is placed, and when the lid is closed, the discharge port 109a of the air pump 109 blows the inner container 10 through the air blowing passage 130 formed in the inner stopper 102 located below.
I am trying to communicate within 7.

However, in such a conventional pump-filled liquid container, a lid 120 with a built-in air pump 109 is placed on the top of the liquid container main body 101, and the air pump 109 is located above the inner stopper 102. Therefore, there was a problem that the height of the entire liquid container became high.

In addition, in this conventional pump injection type liquid container, the pump operation member 119 is provided almost at the center of the top surface of the lid 120, and the pump operation position and the position of the liquid spout 114 are separated by a large distance in the horizontal direction. Therefore, when dispensing liquid, place the liquid receiving container at spout 1.
In addition to the problem that installation work and pump operation below 14 are troublesome, when replenishing liquid to inner container 107 or draining remaining liquid, lid body 120 must be opened and inner stopper 102 must be removed. As a result, replenishing liquid or draining remaining liquid becomes troublesome, and when the inner stopper 102 is removed, it may be difficult to find a place to put the inner stopper 102, or liquid droplets attached to the inner stopper 102 may fall onto the floor surface. There was also the problem of dripping.

(Purpose of the invention) In view of the above-mentioned problems with conventional pump-injection type liquid containers, the present invention has been developed to reduce the overall height of the liquid container, and to improve operations during liquid dispensing, liquid replenishment, and drainage of residual liquid. An object of the present invention is to provide a pump-filling type liquid container that allows each work to be performed easily and prevents liquid droplets attached to the stopper from falling onto the floor surface when the stopper is opened. It is.

(Means for achieving the object) The present invention blows pressurized air from an air pump into the inner container housed in the liquid container main body, and uses the pressurized air to blow the liquid inside the inner container inside and outside the inner container. In a pump-filling type liquid container that is capable of dispensing to the outside through a communicating liquid dispensing passage, an air pump is inserted into the liquid container body within a space between the exterior body of the liquid container body and the shoulder of the inner container. It is installed at the same height as the stopper of the liquid supply port, and furthermore, the operating member of the air pump is provided on the spout side of the liquid pouring passage, and the stopper can be operated from the outside. Moreover, the housing is characterized in that it is hinged at the upper rear side of the exterior body so as to be able to rotate in an arc in the vertical direction.

(Function) In this invention, the air pump is installed at the same height as the liquid supply port stopper in the space between the outer case and the shoulder of the inner container, so there is an extra space that has not been used much in the past. can be used effectively. Furthermore, since the operating member of the air pump is provided on the spout side, the pump operating member and the spout are close to each other in the horizontal direction. Furthermore, since the stopper is provided at the liquid supply port of the liquid container body so that it can be operated from the outside, the lid can be omitted, and the overall height of the liquid container can be reduced by the omission of the lid. When replenishing liquid into the container or draining remaining liquid, this can be done simply by opening the stopper. Moreover, since the stopper is hinged so that it can rotate freely in an arc in the vertical direction, the stopper can be easily opened when it is opened. This saves storage space and prevents droplets attached to the stopper from falling out of the liquid container.

(Embodiments) Some embodiments of the present invention will be explained with reference to FIGS. 1 to 6. FIGS. A liquid container is shown.

The pump-filling liquid container of the first embodiment shown in FIG. 1 includes a liquid container main body 1 having an inner container 7 housed in an outer case 3, and a liquid supply port 8 of the liquid container main body 1 that opens and closes. The main components are a stopper 2, an air pump 9 for feeding pressurized air into the inner container 7, and a series of liquid pouring passages 10 communicating between the inside and outside of the inner container 7.

The exterior body 3 is constructed by attaching an annular shoulder member 5 to the upper part of the outer body 4 and further attaching a bottom member 6 to the lower part of the outer body 4.

The shoulder member 5 has a double wall structure including an outer peripheral wall 51 and an inner peripheral wall 52. A portion of the outer peripheral wall 51 is provided with a bulging portion 53 that bulges outward in the circumferential direction, and inside the bulging portion 53 there is a relatively large space that can house an air pump 9 as described later. A large volume cavity 54 is formed. A sliding hole 54a is formed in the upper part of this space 54 to allow the operation plate 19 of the air pump 9 to slide up and down. Further, the inside of the inner circumferential wall 52 of the shoulder member 5 is a plug fitting hole 55. In addition, the inner container 7 is located at the bottom of the plug fitting hole 55.
A liquid supply port 8 is formed which communicates with the upper opening of.

can be opened and closed in an arcuate manner in the vertical direction without removing it from the shoulder member 5. Furthermore, when the stopper 2 is closed, the top surface of the stopper 2 is almost flush with the top surface of the liquid container body 1 (shoulder member 5), and the stopper 2 reduces the height of the entire liquid container. I try not to get too high. Also, this plug body 2
As shown by the chain line 2', it can stand still in the open position on the exterior body 3,
Moreover, the bottom surface 2 of the plug body 2' in the open position of the plug body
The a' portion is positioned directly above the plug fitting hole 55.

The stopper 2 can be locked in a closed state by a stopper locking member 60. The plug locking member 60 is provided at the upper front side of the plug 2, and
By pushing the operating portion 61 horizontally inward against the spring 65, the locking portion 62 on the locking member side is disengaged from the locking receiving portion 63 provided in the plug fitting hole 55, and the lock is released. It's summery.

The inner container 7 is a vacuum insulated double bottle with a narrow upper opening 7a. Further, the outer side of the upper opening 7a of the inner container 7 forms a shoulder portion 7b.

The liquid pouring passage 10 includes a liquid pumping pipe 11 inserted into the inner container 7, a communication pipe 18 installed laterally so as to pass through the shoulder member inner circumferential wall 52 in the inner and outer directions, and the shoulder member inner circumferential wall 52.

In the pump-filling liquid container shown in FIG. 1, the air pump 9 is installed in the space 54 between the exterior body 3 and the inner container shoulder 7b, so that the space, which has not been used much in the past, can be used effectively. This allows the liquid container to be made more compact. Furthermore, since the lid can be omitted on the upper part of the liquid container body 1, the height of the liquid container can be kept low accordingly. Further, by opening only the stopper 2, liquid can be replenished into the inner container 7 from the liquid supply port 8, and the remaining liquid in the inner container 7 can be discharged. Furthermore, since the stopper 2 is hinged 48, there is no need for a place to place the stopper 2 when the stopper is opened, and when the stopper is closed, the underside 2a of the stopper 2 is covered with dust inside the inner container 7. However, when the stopper is opened, liquid droplets attached to the bottom surface of the stopper may drip from the stopper.
In the open position of the plug, the plug is positioned directly above the plug fitting hole 55 from the bottom surface of the plug, as shown by the chain line 2a', and the liquid droplets flowing down from the plug 2 reach the plug fitting hole 5.
