BRIEF DESCRIPTION OF THE DRAWINGS FIG.
Is a thin-walled synthetic resin first container body which stands up from the upper end of the flexible bag-shaped first body portion 2 via the shoulder 3 to the male screw cylindrical first mouth and neck portion 4. A liquid container is stored in the first container.

[0008] Reference numeral 11 denotes a synthetic resin-made erecting a male screw cylindrical second mouth and neck portion 14 via a shoulder portion 13 from the upper end of the second body portion 12 into which the first body portion 2 is inserted and which can be elastically squeezed. Of the second container body.

At the mouth and neck of the first container body 1 and the second container body 11, the first and the first hanging from the lower surface of the cap-like member 21.
The second fitting cylinders 22 and 23 are detachably fitted. 1st fitting tube
A discharge valve 45 is provided at the lower end of 22 and the upper part of the first fitting cylinder is a nozzle.
52, the second fitting tube 23 is hung down from the outer periphery of a top wall 53 projecting outwardly from the nozzle outer surface in a flange shape, and an outside air suction hole 55 is formed in the top wall 53. The upper surface of the outer peripheral portion of the elastic valve plate 46 protruding outward from the fitting tube is elastically pressed against the top wall portion outside the external air suction hole 55 so that the elastic valve plate 46 and the external air suction hole 55 Thus, the outside air intake valve 56 is formed.

In the illustrated example, the cap-like member 21 is formed by a connecting member 31, a valved member 41, and a nozzle member 51.

The connecting member 31 is provided vertically from both the inner and outer portions of the flange-shaped top plate 32 and is an inner cylinder 33 for forming a lower portion of the first and second fitting cylinders.
The outer cylinder 34 is screwed to the outer surface of the second neck 14 while the inner cylinder is fitted watertight to the inner surface of the first neck 4. The inner cylinder 33 has an inward flange-shaped discharge valve seat 35 at its lower end.
Is attached. The inner and outer cylinders 33 and 34 both extend upwardly. As shown in the figure, it is preferable that an intermediate cylinder 36 for screwing the first mouth / neck portion 4 is suspended from the top plate 32, and the short cylinder fitted to the inner surface of the second mouth / neck portion 14 is also suspended from the bottom surface of the top plate. I have. A vent hole 37 is formed in the top plate between the intermediate cylinder 36 and the short cylinder. The ventilation holes will be described later.

The valve-attached member 41 has a discharge valve plate 44 projecting from the lower end of a first fitting cylinder forming cylinder portion 42 fitted water-tightly to the inner surface of the inner cylinder 33 via an elastic connecting piece 43. The lower surface of the outer peripheral portion of the valve plate is placed on the upper surface of the discharge valve seat 35, and the discharge valve plate
The discharge valve 45 is formed by 44 and the discharge valve seat 35. An elastic valve plate 46 protrudes outward from the upper portion of the cylindrical portion in a flange shape. The elastic valve plate will also be described later.

The nozzle member 51 has a large-diameter lower part of the nozzle 52 fitted to the upper outer surface of the cylindrical part 42,
A top wall protruding outward from the outer surface of the nozzle in a flange shape
53, the covering cylinder 54 is hung down from the outer periphery, and the upper portion of the outer cylinder 34 is airtightly fitted to the inner surface of the covering cylinder.
A fitting cylinder is formed. The top wall 53 has an outside air suction hole 55
The outer peripheral portion of the elastic valve plate 46 is hermetically pressed against the lower surface of the top wall portion outside the external air intake hole, and the external air intake valve 55 and the elastic valve plate 46 are used to open the external air intake valve. Form 56.

It is desirable that a nozzle cap 57 is detachably fitted to the nozzle 52.

In the above embodiment, the cap-shaped member
Although the connecting member 31, the connecting member 31, the valve member 41, and the nozzle member 51 are formed, the configuration of these three members can be changed as appropriate, for example, the intermediate tube 36 and the short tube of the connecting member 31. The outer cylinder 34 of the connecting member can be formed by extending the covering cylinder 54 of the nozzle member 51 downward except for the top plate portion between the two. The discharge valve 45 can also have another structure as appropriate. All the members are formed of a synthetic resin material.

In the above configuration, when the second body 12 of the second container body is squeezed after the nozzle cap 57 is removed, the outside air intake valve 56 is closed, so that the gap between the first and second container bodies is removed. Is pressurized, so that the first body 2 of the first container body is squeezed, and the liquid in the first container body opens the discharge valve 45 and is discharged from the nozzle 52. When the second body 12 of the second container body is released, the squeezing of the first body part 2 of the first container body is also canceled, so that the discharge valve 45 is closed, and the second body part 12 of the second container body is elastically restored. As a result, the inside of the second container body is made to have a negative pressure, so that the outside air suction valve 56 is opened, and the outside air flowing through the valve flows into the second container body 11 through the ventilation hole 37.

By repeating the above operation, the liquid in the first container can be poured out. If the liquid in the first container disappears and the first body 2 contracts, the second container 11 is formed into a cap-like shape. After removing from the member 21, the first container body 1 is further removed and replaced with a new first container body containing liquid, and then the second mouth and neck of the second container body 11 is again fitted to the second fitting of the cap-like member 21. It is fitted to the mating cylinder 23.

The double cylinder container shown in FIG. 1 having the above structure has a large inner diameter at the upper part of the nozzle, and as shown in FIG.
A comb handle 63 with a liquid discharge passage 62 is fitted to the inner surface of the upper end of the container, so that the liquid in the first container body 1 by pressing the second container body portion passes through the comb handle 63 and further between the comb teeth 64 and the like. It can also be made to flow out of the small perforated hole. Instead of the comb 61 in the illustrated example, a brush handle similarly provided may be fitted. The above-mentioned comb 61 with a liquid discharging passage is known.

[0019]

According to the present invention, the first fitting fitted to the inner surface of the first mouth and neck of the first container body having the bag-shaped first body 2 which is rich in flexibility has been described. Since the discharge valve 45 is provided at the lower end of the joint tube 22, the outside air does not flow into the first container to oxidize the stored liquid, and the outside air suction valve 56 is provided to prevent the air in the first and second containers from leaking. As a result, the first body of the first container can be squeezed reliably and quickly through the air between the two containers by squeezing the body of the second container.
Since it is 56, even if the gap volume between the two containers increases due to the decrease in the liquid in the first container, the outside air as much as the increased volume flows from the valve and the above-mentioned squeezing does not become inconvenient.

According to the second aspect, the formation of the cap-like member 21 is facilitated.
