This container is formed by plastic blow molding. In the figure, reference numeral 1 is a telescopic container, and the container body 2 has a bellows 3 shape all around, and can be flattened by crushing when empty, so it is convenient to carry. It has a simple structure. The structure of the bellows 3 of the container body 2 has a large outer circumference as it goes in the direction of the bottom surface and has a trapezoidal shape when viewed from the side.
That is, as shown in the cross-sectional view of the blow molding die 6 in FIG. 3 (b), the peak shape of the bellows 6a becomes lower toward the bottom and the contact with the parison 7 is delayed. It is easy to enter the 6a portion, and thus the wall thickness is likely to be uniform. In the blow-molded product, a mouth 4 having a screw for injecting a liquid such as water is projected on the upper surface 2a, and a cap 5 is screwed into the mouth 4 after the injection. is there.

However, in the conventional device as described above, the outer circumference becomes larger toward the bottom surface as shown in FIG. 3 (b). That is, as the distance (L) from the parison 7 to the molding die surface increases, the overall wall thickness decreases, so there is a limit to the depth (H) of the molded product, and there is the problem that so-called deep molding cannot be performed. It was

That is, the central portion 22 of the container body 22
Since a is constricted and widens toward both ends 23 and 26, both ends 23 and 2 are contracted when receiving a pressing force from the outside.
As it goes to 6, the chevron shape of the outer bellows portion 22b is crushed so as to overcome the chevron shape of the inner bellows portion 22b. Therefore, all the bellows portions 22b are held so as to embrace the chevron shape of the inner bellows portion 22b. Is bent in the direction of the center.

As described above, according to the invention described in claim 1, since the container body has a constricted shape from both end face portions to the central portion, it is possible to obtain a deeper bellows portion than ever before. It has a thick wall and can be molded evenly, and it is possible to form an expandable container that does not expand locally. Further, at the time of contraction, the bellows portion is deformed and flattened so as to embrace the central portion from both end surface portions, so that it is not bulky.

According to the third aspect of the present invention, the seal tube, which is the cock member, and the discharge tube have good liquid-tightness, and even if the weight of the liquid injected into the container is heavy, outside air enters the container. Since it is not sucked in, it does not deform so that the space inside the container expands. In addition, there is no water or air leakage even when pressing force is applied from the top surface side, so it reliably contracts from the bellows part to exert the function of the pump and discharge without disturbance, so it can be divided into cups etc. Is also easy.
