(Prior Art) A distribution container provided with a flexible plastic bag has been already disclosed in, for example, Japanese Patent Publication No. 49-44629 and is widely used as a dispenser for pharmaceuticals, cosmetics and the like. After that, a device in which the shape of the plastic bag is variously modified and improved is also disclosed.

However, the flexible plastic bag has poor shape retention as a whole, making it difficult to store it in a protective container.
As the contents decrease in wrinkles, if there is only one passage for guiding the contents to the lower opening of the cylinder, this passage should be part of the bag when sucking the contents. If is sealed, it must be used even though the contents remain inside the bag. In order to solve this, a passage portion (see 11 and 12 in FIG. 1) for sucking the contents is provided from the upper portion inside the plastic bag. However, the neck portion of the plastic bag is originally attached to the edge portion of the opening of the protective container in a so-called outward state, so that there is an inevitable constant distance between the falling portion of the neck portion and the outer peripheral surface of the cylinder. Even if the plastic bag is generated (see the dotted line in Fig. 2) and the plastic bag shrinks with the release of the contents, this interval is not reduced. Therefore, the contents are left outside in the closed space part based on this interval. It will not be released (see the chain line in Figure 2), making it uneconomical. In addition, a device for solving these disadvantages has a complicated structure by requiring other accessory parts.

Hereinafter, referring to the drawings showing an embodiment, FIG. 1 is an overall view in which a main part of a pump container is cut away, in which FIG.
Is a protective container, 2 is a flexible plastic bag, 3 is a fixed cap, 4 is a cylinder, 5 is a plunger piston, and a cylinder 4 accommodating a pump portion having a plunger piston 5 and the like is provided on the upper surface of the fixed cap 3. The fixing cap 3 is detachably fixed by fitting the outer diameter portion 3a of the fixing cap 3 to the neck portion 1a of the protective container 1 while incorporating the fixing cap 3 in the provided hole portion. Reference numeral 3b designates a cylindrical portion for sealing of the fixed cap 3, which hangs from the lower end surface of the cap with a large outer diameter of the cylinder 4 to form an outer wall of an upper portion 4a of the cylinder 4. The plastic bag 2 has a large-capacity bag portion 6, a neck portion 1a of the protective container 1 having a large inner diameter, and a flange 8 at the mouth portion.
And the wall thickness of the flange 8 and the neck portion 7 is several times larger than the wall thickness of the bag portion 6. The bag 2 accommodates the bag portion 6 and the neck portion 7 inside the protective container 1, and the flange 8 in the protective container 1.
The upper end surface of the neck portion 1a of the
It is clamped and fixed by. The inner end 8a of the flange 8 is received and stabilized by the annular rib 3c protruding from the lower surface of the fixed cap 3.

The neck portion 7 of the plastic bag 2 is inclined toward the sealing tubular portion 3b of the fixed cap 3 at the boundary portion 9 which is gradually thinned from the lower portion toward the bag portion 6 so that the cylinder 4
A constricted portion 10 having rigidity that is constricted toward the outer peripheral surface is provided. In the protective container 1, the neck portion 7 portion of the plastic bag 2 makes the inner surface of the neck portion 10 contact with the lower end portion of the sealing tubular portion 3b of the fixed cap 3 over one round to form a seal portion a, or similarly. The inner surface of the constricted portion 10 is located below the seal portion (a) over the entire circumference of a portion of the outer peripheral surface of the cylinder 4 which is exposed between the lower end portion of the sealing tubular portion 3b and the upper end portion of the connecting cylinder 14 described later. By making contact with each other to form the seal part B, the inside of the bag part 6 and the neck part 7
The inner space 7a is cut off. Even when the contents 11 are reduced, the contents 11 of the bag 6 are prevented from entering the contents 7a of the neck 7 by the sealing portion B or B. Further, the suction tubular portion formed of the passage tube 12 and the connection tube 14 is
The suction pipe 13 is fitted to the passage cylinder 12 and the connecting cylinder 14 is set in the cylinder 4 with the lower cylinder 4b fitted in the lower cylinder 4b. The inside of the bag portion 6 and the lower opening are communicated with each other via the pipe 13. At this time, the starting end port 15a of the groove 15
A predetermined length is ensured between (the upper end of the suction tubular portion 12) and the seal portion a or the seal portion b. As a result, the contents 11 of the bag portion 6 are supplied upward from the starting end port 15a of the concave groove 15 and downward from the lower end 13a of the suction pipe 13 to the lower surface opening of the cylinder 4. Therefore, even if either the lower end 13a of the suction pipe 13 or the starting end port 15a of the recessed groove 15 is sealed by the bag portion 6, the content in the bag portion 6 is transferred from the other to the lower opening of the cylinder 4. Will be sent.

(Operation / Effect) As is apparent from the above, in the pump container of the present invention, the plastic bag has a thick neck portion, and is constricted toward the cylinder outer peripheral surface from the neck portion to the boundary portion with the bag portion. A constricted part is provided, and the inner surface of the constricted part is contacted with the outer peripheral surface of the cylinder or the lower end of the sealing tubular part of the fixed cap over the circumference, respectively, and a seal part for interrupting the inside of the bag and the space inside the neck is provided. Since it is built-in, the contents of the bag part can be prevented from entering the inner space of the neck while the pump container is in use, and the disadvantages that have been left in the inner space of the neck, which have occurred in the past, can be completely removed, and the structure is simple. Easy to do.

Further, since the upper end of the suction tubular portion close to the constricted portion and the lower end of the suction pipe are used as the passage of the contents to the lower opening of the cylinder, one of them is sealed by the bag portion. Even in the case of using the other, by using the other, the contents in the bag can be smoothly and reliably sent to the lower opening of the cylinder.
