This simplifies the manufacturing process of the top closure member 2 and improves the productivity of the container. As the resin material for the top closing member 2, low density polyethylene, high density polyethylene, linear low density polyethylene, copolymer or mixture of polypropylene and polyethylene, etc. are used.

FIGS. 5(a) to 5(C) are partially enlarged sectional views for explaining the seam 12 of the blank plate 11 which is wound into a cylindrical shape to form the body member 1. FIG.

In FIG. 5(a), a film 13 is attached and connected from the outside (top of the drawing) and the inside (bottom of the drawing) so that the ends of the rolled blank board 11 face each other.

Moreover, in FIG. 5(b), the vicinity of the edges of the blank plates 1 are overlapped and bonded together, and a film 13 is bonded to the inside for connection. The reason for pasting the film 13 on the inside in this way is to prevent the edges of the blank board 11 from being exposed inside the container and coming into contact with the contents. In addition, Fig. 5 (C
) is a blank board 11 that is wound around and has a folded part 11a on one of the opposing edges, and is bonded and connected so that the blank board provided with the folded part 11a is on the inside of the container. In the present invention, various joint configurations other than those shown in FIG. 5 can be used, but the engaging portion 22
Considering the adhesion between the two parts, the joint shown in FIG. 5(a) is preferable.

Note that the blank board used in the present invention may be a multi-layered stack of various materials, for example, from the front side, polyethylene (PE) layer/paper/PE layer/aluminum layer/
Polyethylene terephthalate (PET) layer/PE layer 6
It may also have a layered structure. In addition, PE layer/paper/PE
It may have a multilayer structure such as a layer.

Furthermore, in the present invention, a cylindrical body previously formed into a tube shape may be used as the body member, instead of being formed by winding a blank plate as described above.

FIGS. 6(a) and 6(b) are partial sectional views for explaining the formation state of the bottom closing portion 2. FIG. First, the bottom plate member 31, which is the bottom closing member 3 formed into a U-shaped cross section, is placed inside the bottom side of the body member 1, and the flange portion 31a of this bottom plate member 31 is inserted.
The outer periphery of the body member 1 is fused to a suitable position on the inner periphery of the body member 1 (FIG. 6(a)). Thereafter, the protruding portion 1a of the body member 1 is curled toward the flange portion 31a, and the protruding portion 1a is pressurized and fused to the inner peripheral portion of the flange portion 31a. As a result, the bottom closing portion 3 is formed (FIG. 6(b)).

Note that the structure of the bottom closing portion is not limited to that described above. The material of the bottom closing member 3 can be appropriately selected from the same material as the blank plate of the body member 1, aluminum, various plastics, etc.

As described above, in order to load contents and produce a container using the body member 1, top closure member 2, and bottom closure member 3 formed respectively, first, the bottom closure member is attached to the bottom of the body member 1. 3 is fused and then the contents are loaded, and the top closure member 2 is fused and fixed to the body member 1.

When dispensing the contents from the container thus formed, first, the hook portion 24b of the opening/closing member 24 is pulled up in the direction A in FIG. 2. As a result, the thin opening portion 25 is torn. Then, the opening/closing member 24 swings in the entry direction centering on the thin hinge portion 26, and the spout appears. At this time, the opening holding member 24e on the swinging base 24d side of the opening/closing member 24.

24e contacts the surface of the front lid part 21a of the lid part 21 (position B in FIG. 2). However, since the opening/closing member 24 is made of a flexible material and is longer than the step as described above, the opening holding member 24e is not connected to the front lid part 21 of the lid part 21.
The opening/closing member 24 while rubbing against
further swings in the A direction. Then, when the opening/closing member 24 swings by a certain angle, the opening holding member 24e of the opening/closing member 24
is repelled toward the tip of the front lid portion 21a (to the right in FIG. 2) and becomes straight, and the opening/closing member 24 is held with the spout 23 open (position D in FIG. 2). and,
By grasping and tilting the container, the contents are smoothly poured out by the liquid guide portion 23a of the spout 23. At this time, the opening/closing member 24 is stationary at the position ff1D in FIG. 2, and does not swing unless a manual force is applied in the direction of closing the spout 23 (in the direction of arrow C in FIG. 2). Therefore, the spout 2 can be opened without holding the opening/closing member 24 of the lid part 21 by hand.
The contents can be poured out from step 3. In addition, when swinging the opening/closing member 24 in the closing direction, it is sufficient to perform the opposite operation to the above-mentioned case, and even after opening the opening/closing member 24, the spout 23 is closed again and the contents are poured out. Can be saved. In this case, by pressing the opening/closing member 24 against the spout 23, the lower end protrusion 24a of the opening/closing member 24 is pushed inside the upper end 23b of the spout 23 and is locked therein.

In the above embodiment, the bottom closing member 3 was fused to the body member 1, and then the contents were loaded and the top closing member 2 was fused. After being fused, the contents may be loaded, and then the bottom closure member 3 may be fused to the body member 1.

Further, although the body member 1 is a cylinder with an elliptical cross section in the above-described embodiment, the shape is not limited to this, and the body member 1 may be a cylinder with an arbitrary cross-sectional shape such as a circle or a polygon. can.

〔Effect of the invention〕

As described above, the present invention is equipped with a rising-shaped liquid guiding part at the spout, so that the flow of the contents at the time of pouring becomes smooth and dripping can be prevented. By providing this, the spout can be closed and stored even after it has been opened, and the opening/closing member can be kept open during pouring, which is convenient. Furthermore, the design is excellent, and since the top closing member is integrally molded, production costs can be reduced.
