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.

(Embodiments) Several embodiments of the present invention will be explained with reference to FIGS. 1 to 4. 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 peripheral wall 52 of the shoulder member 5 serves as a plug insertion hole 55, and the inner surface of the plug insertion hole 55 is formed with a female thread for screwing the plug body. Further, a liquid supply port 8 communicating with the upper opening of the inner container 7 is formed at the lower part of the plug insertion hole 55 . Further, a horizontal step portion 56 is formed near the upper portion of the plug insertion hole 55 .

The plug 2 is detachably screwed into the plug insertion hole 55, and when the plug 2 is tightened, the plug 2 is inserted into the plug insertion hole 55.
The upper surface is made to be substantially flush with the upper surface of the liquid container main body 1 (shoulder member 5), so that the height of the entire liquid container is not increased by the stopper 2. Further, a large diameter portion 21 is formed in the upper part of the plug body 2 to cover the upper surface of the horizontal stepped portion 56 of the plug insertion hole 55.

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 dispensing passage 10 includes a liquid pumping pipe 11 inserted into the inner container 7, an intra-stop liquid passage 12 provided in the stopper 2, and a dispensing pipe connected to an outlet 12a of the intra-stop liquid passage 12. It is configured with an auxiliary pipe 13.
The liquid pumping tube 11 is integrally attached to the lower surface of the plug body 2, and the upper end of the liquid pumping tube 11 communicates with the proximal end (lower end) of the liquid passage 12 in the plug.
The tip (outlet) 12a of the liquid passageway 12 in the stopper is connected to the stopper body 2.
It is made to face downward from a hole 22 formed in the lower surface of the large diameter portion 21 of the main body. A water stop valve 16 is provided in the stopper liquid passage 12 in case the liquid container falls over.

On the other hand, a hole 57 is formed at the front side of the horizontal stepped portion 56 of the plug insertion hole 55.
The upper opening of the pouring auxiliary pipe 13 is connected to the lower part of the pipe.

When the plug body 2 is completely screwed into the plug insertion hole 55, the outlet 12a of the liquid passage 12 in the plug is positioned directly above and adjacent to the hole 57 of the horizontal stepped portion 56 of the plug insertion hole. This ensures that the entire amount of liquid discharged from the outlet 12a of the liquid passageway 12 in the stopper when dispensing liquid flows into the auxiliary dispensing pipe 13 through the hole 57.

The auxiliary spouting pipe 13 is installed diagonally downward and forward, and the lower end of the auxiliary spouting pipe 13 serves as the spout 14 of the series of liquid spouting passages 10 .

The air pump 9 is of a bellows type. This air pump 9 is installed in a space 54 between the exterior body 3 and the inner container shoulder 7b. That is, in this first embodiment, the air pump 9
is a space 5 provided between the front wall 53a of the shoulder member bulging portion 53 and the inner container shoulder portion 7b, which is a part of the exterior body 3.
It is installed at a position directly above the spout 14 in the spout 4 and at the same height as the plug 2 so as not to interfere with the plug 2 in the vertical direction. Further, a pump operation plate 19 is installed above the air pump 9 so as to be vertically movable within the sliding hole 54a.

In the pump-filling liquid container shown in FIG. 1, the air pump 9 is installed at the same height as the stopper 2 in the space 54 between the outer case 3 and the inner container shoulder 7b. It is possible to effectively utilize a space that is not used much, and it is possible to make the liquid container more compact (reducing its height). Further, in the first embodiment, since the lid can be omitted on the upper part of the liquid container main body 1, the height of the liquid container can be kept even lower. In addition, by simply removing 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, when the pump operation plate 19 is pressed, pressurized air from the air pump 9 is blown into the inner container 7 through a series of air blowing passages 30.
The pressurized air allows the liquid in the inner container 7 to be poured out through a series of liquid pouring passages 10 from a spout 14 at the tip thereof. At that time (during liquid pouring operation), the pump operation part is located directly above the spout, and the pump operation position and the liquid pouring position are close to the horizontal direction (overlapping), so the spout 1

The pump injection type liquid container of the second embodiment shown in FIG. 2 shows a modification of the air blowing passage 30 portion of the pump injection type liquid container of the first embodiment. The air blowing passage 30 connects a flexible pipe (for example, a silicone pipe) 34 between a hole 95 provided in the top plate 91 of the air pump 9 and a hole 71 provided in the inner container shoulder 7b. It is configured by being connected to a passage member 33 having a water stop valve 32 at the time.

In the pump liquid container of the third embodiment shown in FIG. 3, an inward portion 9a of the air pump 9
is expanded toward the center of the liquid container body 1 until it approaches the outer surface of the inner peripheral wall 52 of the shoulder member than in the case of FIG. 1, thereby increasing the capacity of the air pump 9.
A vertical through hole 98 defined by an inner bellows tube 97 is formed in the part of the air pump 9 that bulges toward the center of the liquid container. is installed. In this way, even if the air pump 9 is bulged toward the center of the liquid container, a space for mounting the auxiliary pouring pipe 13 can be secured. The air blowing passage 30 from the air pump 9 is constructed by directly fitting the tip of a discharge pipe 35 integrally formed on the pump bottom plate 93 into a cylindrical packing 72 provided in a hole 71 in the inner container shoulder 7b. are doing. In this way, the number of parts constituting the air blowing passage 30 can be reduced. Plug body 2
A silicon pipe is used for the upper half portion 17 of the liquid passage 12 inside the stopper. Further, the tip 12a of the upper half portion 17 of the liquid passageway 12 projects slightly downward from the lower surface of the large diameter portion 21 of the stopper, so that when the stopper 2 is completely tightened, the liquid inside the stopper is removed. The tip 12a of the passage 12 is the hole 5 of the horizontal stepped portion 56 of the plug insertion hole.
It is designed to be watertightly connected to the mouth edge of No.7.

It is installed in an annular space 54 between an outer circumferential wall 51 and an inner circumferential wall 52 of the shoulder member 5. Moreover, this air pump 9 has the following characteristics depending on the size of the annular space 54:
The shoulder member 5 is thick on the side where the bulging portion 53 is formed, and gradually becomes thinner toward the opposite side, so that the capacity inside the air pump 9 can be made as large as possible. This air pump 9 uses a flexible membrane material 96 instead of a bellows type, and a pump top plate 91 provided on the top of the membrane material 96.
One end on the side opposite to the pump operating section is pivotally supported by a shaft 99 outside the membrane material 96. When the pump operation plate 19 is pressed, the pump top plate 91 pivots downward about its one end pivot (shaft 99), thereby compressing the air pump. In addition, when operating the pump, the air pump 9
The pump top plate pivot side portion 9b hardly expands or contracts. Further, in this fourth embodiment, the plug body 2 is of a type that is simply hooked onto the mouth edge of the liquid supply port 8. A short and small discharge pipe 15 is connected to the outlet side of the internal liquid passage 12 provided in the stopper 2, and when the stopper is installed, the distal end 15a of the discharge pipe 15 is connected to the proximal end opening of the auxiliary ejection pipe 13. 13a. Further, in this fourth embodiment, a lid body 20 is provided on the upper part of the shoulder member 5. The lid 20 is pivoted at the rear end 20a of the lid 20 to the upper rear side of the shoulder member 5 with a pin 48 so as not to overlap the pump operation plate 19 vertically. The front portion 20b of the lid 20 is locked by a lid locking member 60. This lid lock member 60
is provided on the upper part of the shoulder member 5 so as to be able to slide in the outward and outward directions, and can be unlocked by pushing the operating section 61 of the lid locking member 60 outward against the spring 65.
