A handle 62 may be attached to the intermediate portion of the stopper as shown.

Reference numeral 71 denotes a cap, which is provided if necessary.

The container having the above structure can be assembled as follows.

Cylinder 13 previously forming a part of the pump body
The mouth 32 of the pack 31 having an opening at the lower end is joined to the lower outer surface of the lower part of the pack 31 so that the mouth is airtightly closed.
The pack and cylinder are filled with an appropriate amount of liquid and nitrogen gas through the lower end opening of the pack, and after filling, the pack lower end opening is sandwiched in a plate shape and sealed. By filling the liquid and gas with a margin, the pack is put into the container body by, for example, rolling the pack into a C-shaped cross section, and the upper part of the cylinder 13 is fitted to the inner surface of the mouth and neck. Next, the mounting cylinder 42 of the supporting cylinder member is fitted to the outer surface of the mouth and neck of the container body, the lower part of the stem 54 of the press-down head 51 is further fitted to the inside of the guide cylinder 44, and the female screw part of the lower part of the outer peripheral wall 55 is mounted to the mounting cylinder. It is screwed into a male screw portion on the upper outer surface of 42, and the stopper 61 and the cap 71 are fitted if necessary.

At the time of use, the consumer first removes the cap and stopper 61, then cuts down the sheet 21 by the cutter 57 at the lower end of the stem by screwing down the press-down head 51, and then screwing down the sheet 21 to the outer surface of the connecting cylinder 16 The lower inner surface of the stem 54 is connected so as not to be pulled out tightly. When the connection is completed, the female screw portion 56 formed by the lower portion of the outer peripheral wall moves below the male screw portion 45 formed by the upper portion of the mounting cylinder 42. Therefore, in this state, the press-down head 51 and thus the piston 15 can be moved up and down together with the stem at the distance between the lower end of the external thread portion 45 and the outward flange 46.

After the pressing head can be moved up and down as described above, the nitrogen gas in the pack and the cylinder can be discharged by moving the pressing head up and down several times.
After the gas is discharged, the liquid in the pack can be discharged by the same operation as that of a conventionally known pump, the pack shrinks due to the decrease in the liquid in the pack, and the negative pressure in the container body due to the shrinkage of the pack The problem can be solved by the inflow of outside air from the outside air inflow hole 6 formed in the bottom plate 5 of the body.

In the case of the second embodiment shown in FIGS. 3 to 5, a cylinder 82 of a liquid filling guide member 81 is fitted between the inner surface of the mouth and neck 2 and the cylinder 13, and the cylinder The mouth of the pack 31 is hermetically bonded to the outer surface.

The liquid filling guide member 81 has a plurality of connecting plates 83 projecting inward from the lower end of the cylindrical portion 82, and a plurality of grooves 84 having a cross-shaped cross section extending from the inner ends of the connecting plates to the outer surface. The provided guide rod 85 is suspended down to the inside of the bottom of the pack 31. The upper portion of the cylindrical portion 82 is formed as a large-diameter portion 86 via an outward flange-like portion, and the large-diameter portion is fitted into the large-diameter portion 4 of the neck portion of the container body. The upper end of the large diameter portion 86 is covered up to the outer surface. Also, an appropriate number of gas discharge grooves are formed in the upper surface of the retaining tube 17, and the sheet 21 is adhered to the upper end surface of the cylindrical portion.

The other parts may be the same as those in the first embodiment, and thus the same reference numerals are given and the description will be omitted.

In the case of the second embodiment, first, after the pack 31 is attached as shown in FIG. 4, the guide member 81 is put into the container, and the cylindrical portion 82 is fitted into the mouth and neck of the container. From this state, the liquid is filled into the pack using a filling nozzle 87 provided separately, and then the pump body 11 is fitted into the cylindrical portion 82 of the guide member 81 as shown in FIG. At the time of the fitting, the nitrogen gas in the cylindrical portion 82 is supplied to the suction valve 14 and the discharge valve hole.
Opening 18 enters the cylinder, and is discharged outward through the gas discharge groove. After the fitting of the pump body, the outer peripheral portion of the seat 21 is joined to the upper end surface of the cylindrical portion 82 to seal the upper surface of the cylindrical portion.

Subsequent support cylinder member 41 and push-down head
The assembly of 51 may be performed in the same manner as in the first embodiment.
In this embodiment, the coil spring 22 is interposed between the inward flange 43 of the support cylinder member and the lower surface of the top plate of the pressing head. The cylinder 19 may be urged upward, and the case of the first embodiment may be the same as that of the second embodiment.

The container may be used in the same manner as in the first embodiment.

FIGS. 6 and 7 show a third embodiment. This embodiment is almost the same as that of the second embodiment. The upper end of the cylindrical portion 82 is formed as an outward flange 88, and the flange is engaged with the upper surface of the upward step 3 on the inner surface of the upper part of the mouth and neck of the container body. In the same manner as in the case of the embodiment, the outer peripheral surface of the outward flange 12 at the upper part of the cylinder and the outer cylindrical portion of the retaining pipe 17
It is fitted to the inner surface. In the case of this embodiment, the retaining tube 17
There is no gas exhaust groove on the upper surface. Therefore, the sealing of the upper surface of the retaining tube 17 by the sheet 21 is performed after the cylinder is fitted to the inner surface of the cylindrical portion. In the case of this embodiment, the cylinder 13 is attached to the cylindrical portion 82, and a retaining pipe is provided at the upper end of the cylinder.
17 are fitted airtightly, and the upper surface of the retaining tube is sealed with a sheet 21. Sealing with the sheet,
The outside air is prevented from flowing into the pack 31 and the pump body 11 at least until the sheet is broken, and any structure may be used as long as the sheet is broken.

[0029]

According to the first aspect of the present invention, the stored liquid is not exposed to the outside air at least until the sheet 21 is broken, that is, until the sheet is broken by the consumer. Absent.

Further, when the press-down head 51 is lowered with respect to the support cylinder member 41, the lower end of the stem 54 breaks the sheet 21, and the lower part of the stem is fitted to the outer surface of the connection cylinder 16 in a water-tight manner so as to be integrally connectable. At this time, the female thread 56 at the bottom of the outer peripheral wall of the press-down head
Moves below the male screw part 45 at the upper part of the support cylinder member mounting cylinder, and from this state, the piston part 15 with the discharge valve is moved up and down in the cylinder 13 with the suction valve 14 via the press-down head 51. Therefore, it is easy to suck the liquid in the pack 31 into the cylinder and discharge the liquid in the cylinder.

In the case of the second aspect of the invention, in addition to the effect of the first aspect, the provision of the liquid filling guide member 81 facilitates the liquid filling, and the pump body 11 is fitted into the container body neck and neck in advance. The fitting of the pump main body is facilitated because it is only necessary to fit the inner surface of the combined guide member tubular portion 82.

According to a third aspect, the pack 31 and the sheet
By using 21 as a laminated sheet made of a synthetic resin containing an aluminum layer, the effect of preventing oxygen permeation is enhanced, and the effect of blocking light is also obtained.

By enclosing nitrogen gas in the pack and the cylinder as in claim 4, oxidation of the stored liquid can be prevented more reliably.

By providing the stopper 61 as in claim 5, it is possible to prevent the pressing head 51 from being accidentally screwed down and the sheet 21 from being broken.
