Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof small bag made of synthetic resin.

[0002]

2. Description of the Related Art For example, a small bag made of water-resistant synthetic resin and flexible for storing and carrying a toothpaste is used. The bag is formed of a soft synthetic resin sheet, and is attached to one half of the bag mouth. The hooks and other fasteners attached to the inside of the bag can be fixed to the hooks and the like attached to the outside of the bag body. It is provided so that it can be opened and put things in and out.

[0003]

Since the conventional bag is formed of a soft sheet, it is inconvenient to open and close the mouth of the bag. There was a disadvantage that it was easy to move.

According to the present invention, the bag body is formed of a synthetic resin cylindrical body having a closed lower end surface, and a mouth formed by the upper end of the cylindrical body, which is normally open due to elasticity, is attached to the mouth. It can be closed by the mouth mounting member
The mouth is provided so that the mouth is elastically restored and automatically opened by the rotation of the lid plate of the mouth mounting member, thereby eliminating the above-mentioned drawbacks.

[0005]

Means for Solving the Problems In the front half 3 of the upper end of the peripheral wall of the elastic synthetic resin cylindrical body 2 having the upper end opening with the lower end closed.
The bag body 1 having the arc-shaped concave portion 4 and the insertion hole 6 formed in the center of the rear half portion 5 of the peripheral wall behind the concave portion, and the stopper pin 9 inserted through the insertion hole 6 are connected to the peripheral wall behind the concave portion. An engaging plate 10 protrudes from the front surface of the engaging plate 10 in contact with the rear surface of the rear half portion 5, and a lid plate 12 protrudes from the engaging plate portion where the upper end of the peripheral wall rear portion 5 is located via a thin hinge 11. A mouth mounting member 8 provided with an arch-shaped hanging portion 15 between the left and right portions of the upper end surface. The cover plate 12 is rotated around the thin hinge 11 to be attached to and detached from the stopper pin 9. A stopper hole 14 to be freely fitted is formed in the cover plate 12, and the projecting length of the cover plate is set to be larger than the length of the recess 4 in the depth direction.

[0006]

When the cover plate 12 is opened from the closed state of the cover plate 12 shown in FIGS. 1 and 2 as shown in FIG. 3 and as shown by the two-dot chain line in FIG. It moves forward and opens due to elastic recovery. When the cover plate 12 is closed from the open state, the upper front half portion 3 of the peripheral wall is again pressed by the inner surface of the cover plate 12 as shown in FIGS.
It is pressed to the side to close the mouth.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a bag body. The bag body has an arc-shaped recess 4 in an upper front half 3 of a peripheral wall of an elastic synthetic resin cylindrical body 2 having a closed lower end face and an upper end face opening. An insertion hole 6 is formed in the center of the rear half 5 of the peripheral wall. The lower end surface of the cylindrical body 2 may be closed by bonding a disk-shaped bottom wall 7 to the lower end surface of the cylindrical body as shown in the figure, or the lower end of the cylindrical body may be formed in a flat plate shape as in a normal tube container. It may be carried out by welding in a shape crushed into a shape. The cylindrical body is formed by extruding, cutting to a predetermined size, and closing its lower end.

Reference numeral 8 denotes a mouth-mounting member, which engages the stop pin 9 inserted through the insertion hole 6 with the rear half 5 of the peripheral wall behind the recess 4.
It protrudes from the front surface of the engagement plate 10 that is in contact with the rear surface of the engagement plate 10.
The stop pin 9 may have a slightly larger diameter at its front end. Further, a lid plate 12 protrudes from the engagement plate portion where the upper end of the rear half portion 5 of the peripheral wall is located via a thin hinge 11. The thin hinge may be provided at the tip of the overhang plate 13 projecting from the engagement plate as shown. The cover plate is provided with a stop hole 14 into which the stop pin 9 is fitted. Further, an arch-shaped hanging portion 15 is provided between the left and right portions of the upper end surface of the engaging plate 10. Cover plate 12
Is longer than the depth of the concave portion 4 provided in the upper front half portion 3 of the peripheral wall, and as can be understood from FIG. 1, by closing the lid plate 12 from the open state, the upper front half portion 3 of the peripheral wall is opened. Is provided so as to be pressed against the inner surface of the cover plate 12 and pressed toward the upper rear half portion 5 of the peripheral wall. The lower end of the cover plate 12 may be slightly curved outward, so that a finger can be easily hooked on the tip of the cover plate when the cover is opened.

The mouth mounting member 8 is integrally formed of a synthetic resin material.

Reference numerals 16 and 17 denote a tube container and a toothbrush which are stored in the bag body.

[0011]

According to the present invention, as described above, since the bag body is formed of an elastic synthetic resin cylindrical body, the thin hinge 11 is moved from the closed state of the cover plate 12 in which the stopper pin 9 is fitted into the stopper hole 14. At the same time when the lid plate 12 is opened by the rotation about the center, the upper half of the upper end of the peripheral wall of the cylindrical body 2 is moved forward by elastic restoration to open the mouth formed by the upper end of the peripheral wall, and the upper half of the upper end of the peripheral wall is opened. Cover plate than the length in the depth direction of the concave portion 4 provided in the portion
Since the protruding length of 12 is increased, the upper end front half portion 3 of the peripheral wall, which protrudes forward as described above due to the closure of the lid plate around the thin hinge 11 as a center, is moved upward by the inner surface of the lid plate. The opening formed by the upper end of the peripheral wall is closed by being pressed against the portion 5 against elasticity, so that the opening and closing of the opening can be performed easily and quickly.
