SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a body member having a top opening formed by a flexible synthetic resin sheet, and an upper end of the body member. A lid member made of a synthetic resin molded body that closes the opening; and a lid plate that covers an upper end opening of the trunk member, the lid member is provided continuously with a peripheral edge of the lid plate, An object of the present invention is to provide a spout-equipped container having an annular peripheral wall that is heat-welded to an upper end portion, and a spout serving as a spout or a spout is attached to the lid plate.

In the spout-equipped container constructed as described above, since the lid member to which the spout is attached is formed of a synthetic resin molded body having a certain shape-retaining property, the peripheral wall of the lid member is formed. By heat-welding to the upper end opening of the trunk member, the upper end opening of the trunk member is reliably held in an open state, and the internal capacity of the trunk member can be sufficiently ensured.

Further, unlike the case of attaching the spout to the gusset portion of the gusset bag, it is not necessary to perform a cumbersome and difficult operation such as attaching the spout after forming the gusset portion, and it is possible to maintain the spout in advance to a certain extent. Since it is only necessary to heat-weld the shaped lid member to the upper end opening of the body member, there is also an advantage that it is easy to manufacture.

Further, as in the case of the container with a spout according to claim 2, the lid member has the lid plate connected to a lower edge of the peripheral wall, and the lid member is connected to an upper end opening of the trunk member. When the outer peripheral surface of the peripheral wall of the lid member is thermally welded to the inner peripheral surface of the trunk member over the entire periphery thereof in a state where the lid member is fitted into the lid member, the lid member is closed at the upper end opening of the trunk member. After being fitted into the lid member, the outer peripheral surface of the peripheral wall is brought into close contact with the inner peripheral surface of the trunk member by expanding the peripheral wall of the lid member radially outward, and the upper end portion of the trunk member and the lid are then closed. The member can be easily manufactured by the manufacturing method according to claim 5, wherein the peripheral wall of the member is thermally welded.

Further, as in the case of the container with a spout according to claim 3, a central portion of the lid plate to which the spout is attached is left except for a peripheral portion of the lid plate to which the peripheral wall is continuously provided. In the case where the spout is projected upward, the spout attached to the lid plate projects from the upper end of the body member, so that there is an effect that it is easy to drink when directly drinking the contents from the spout.

Further, in the container with a spout according to the fourth aspect, the center portion of the cover plate to which the spout is attached is formed so as to protrude downward, Since the spout is retracted to the lower side of the body member by projecting the center portion in advance downward, in the above-described manufacturing method, after the lid member is fitted into the upper end opening of the body member. When the peripheral wall of the lid member is pushed outward in the radial direction, the spout does not hinder the operation of expanding the diameter of the lid member, and the spout can be efficiently manufactured. After the upper end opening of the trunk member is closed by the lid member, by protruding the central portion of the lid plate upward, an effect is obtained that when the content is directly drunk from the spout, it is easy to drink. Needless to say.

Expanding claw 5 that pushes the peripheral walls 22 and 32 of 0 radially outward.
The central portions of the protruding lid plate 21 and the bottom plate 31 do not come into contact with 2c, and the operation of expanding the lid member 20 and the bottom member 30 can be performed without any trouble. In addition, as for the cover member 20, the spout 40 attached to the cover plate 21 is retracted to the lower side of the body member 10 by projecting the center portion of the cover plate 21 downward in advance, so that It can be said that this is particularly effective when the above-described manufacturing method is adopted.

In this embodiment, the lid member 20 having the central portion of the lid plate 21 protruding upward and the bottom member 30 having the central portion of the bottom plate 31 protruding downward are used. , But is not necessarily limited to this, for example,
As shown in FIG. 9, the cover plate 21 can be formed in a flat shape.

In this embodiment, the cover member 20 having the peripheral wall 22 rising upward from the peripheral edge of the cover plate 21 is fitted into the upper end opening of the body member 10, but the present invention is not limited to this. It is not a thing, for example, FIG.
As shown in (a) and (b), the lid members 20a and 20b whose peripheral walls 22a and 22b hang down from the peripheral edges of the lid plates 21a and 21b.
It is also possible to adopt a configuration in which the peripheral walls 22a and 22b are thermally welded to the body member 10 in a state where Ob is externally fitted or fitted in the upper end opening of the body member 10.

In this embodiment, the peripheral wall 22 is simply heat-welded to the body member 10 with the lid member 20 fitted in the upper end opening of the body member 10. For example, FIG. As shown in (a), a folded portion 11 is continuously provided at the upper end of the trunk member 10, and the folded portion 11 is folded inside the upper end of the trunk member 10 to which the lid member 20 is attached, and is bonded to the peripheral wall 22. As shown in FIG. 2B, a folded portion 23 is continuously provided at the upper end of the peripheral wall 22 of the lid member 20, and the folded portion 23 is folded outside the trunk member 10 to form an outer peripheral surface of the trunk member 10. Or a cover member 24 having a peripheral wall 26 hanging down from a peripheral edge of a flat plate member 25 is externally fitted to the upper end of the body member 10 to which the lid member 20 is attached, as shown in FIG. If the plate member 25 is bonded to the cover plate 21, the body member 1 In conjunction with the mounting portion of the cover member 20 is reinforced, not exposed cut surface of the synthetic resin sheet on an upper end portion of the body member 10, it is possible to ensure a smooth texture. It is needless to say that such a configuration can be applied not only to the upper end opening of the body member 10 closed by the lid member 20 but also to the lower end opening of the body member 10 closed by the bottom member 30. Nor.

Further, in this embodiment, the bottom member 30 is attached after the lid member 20 is attached to the body member 10, but the lid member 20 may be attached after the bottom member 30 is attached to the body member 10. It is possible. In that case, it is also possible to fill the contents after attaching the bottom member 30 to the body member 20, and then attach the lid member 20.

In this embodiment, the upper and lower openings of the cylindrical body member 10 are closed by the lid member 20 and the bottom member 30, but the present invention is not limited to such a spout. The present invention is not limited to the container provided with
It is also possible to apply the present invention to a tubular spout-equipped container in which the lower edges of the synthetic resin sheet are heat-welded to each other. In that case, as shown in FIG. 3A, by inverting the protruding portion of the cover plate 21 of the cover member 20,
Since the projecting spout 40 enters the inside of the body member 10, it becomes possible to stand such a tube-shaped spout-equipped container with the spout 40 side down.

In this embodiment, the lid member 20 and the spout 40 are formed as separate members. However, both can be integrally formed by injection molding using a synthetic resin such as polypropylene.
