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 A small bag made of water-resistant synthetic resin and flexible for storing and carrying a toothbrush or the like is used.

[0003]

The above water-resistant small bag is formed of a soft synthetic resin sheet, and a cover provided by extending one half of the bag mouth is extended to the other half of the mouth. A stopper such as a hook attached to the inner surface of the tip of the lid by hanging it down can be stopped by a hook attached to the outer surface of the bag body, and when opening the lid, remove the hook and raise the lid, The closed bag mouth is opened so that stored items can be put in and out.

[0004]

Since the conventional bag is formed of a soft sheet, opening and closing the opening of the bag is rather inconvenient, and there is a disadvantage that the opening of the bag tends to take time.

In the present invention, the bag is formed of a cylindrical body having flexibility and elasticity, and an opening in an open state is automatically formed by tilting an opening / closing tool pivotally attached to a part of an upper end of the cylindrical body. When the opening / closing device is closed and inserted into the opening / closing device, and when the opening / closing device is raised from the closed state of the opening and removed from the opening, the opening is elastically restored and the opening is automatically opened. It is provided as follows.

[0006]

Means for Solving the Problems A part of the upper end of a cylindrical body 1 made of a flexible elastic synthetic resin having a closed lower end surface and an opening at the upper end surface is formed as a two-folded folded portion 3. The knob-folded portion is inserted between one end of the two holding plates of the opening / closing tool 4 that hangs the holding plates 7 and 7 in parallel from both longitudinal edges of the narrow band-shaped top wall 6, and the inserted portion together with the two holding plate portions is provided. The opening / closing tool 4 is pivotally connected to the cylindrical body 1 by a stopper pin 5 so as to be rotatable.

[0007]

[Effect] From the opening state of the mouth 13 shown in FIGS. 1 and 3,
In the case of FIG. 1, when the opening / closing tool 4 is turned down after the tube container 15 as a storage object is stored or taken out into the cylindrical body 1, the opening of the cylindrical body is opened, and the holding plates 7, 7 of the opening / closing tool are opened. The mouth is gradually closed from one end against the elasticity due to the pressure contact with the lower end, and the mouth is inserted between the two holding plates. Finally, as shown in FIG. The mouth is closed. When raising the free end side of the opening and closing tool from the state of FIG. 2,
By pivoting around the stop pin 5, the mouth exits from between the two holding plates 7, 7 from the other end side, elastically restores with the exit, and opens again as shown in FIGS.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a flexible elastic synthetic resin cylindrical body having a closed lower end and an open upper end. The cylindrical body may be formed by cutting the extruded synthetic resin cylindrical body to a predetermined size, sandwiching the lower end of the cylindrical body, crushing the lower end, and forming a welded plate-shaped seal portion 2. In the illustrated example, the cylinder is transparent.

[0009] A part of the upper end of the cylindrical body is formed as a two-folded pinch-shaped portion 3, which is inserted into one end of the opening / closing tool 4 and pivotally connected with a stopper pin 5. The opening / closing tool hangs a pair of holding plates 7 and 7 in parallel from both longitudinal edges of the narrow band-shaped top wall 6, and a gap between the holding plates is provided when the upper end of the cylindrical body is closed in a plate shape. The thickness of the plate portion may be substantially the same as the thickness of the plate portion, and the length thereof may be substantially the same as the length of the plate portion. The pivotal attachment is performed by inserting the two-folded knob-like portion 3 between the two holding plates 7 at one end of the opening / closing tool, and rotating the opening / closing tool 4 with respect to the cylindrical body 1 with the holding pin together with the two holding plates. Pivots as much as possible. The stop pin 5 of the first embodiment shown in FIGS. 1 and 2 is formed of a short pipe, and after pivoting, both ends of the short pipe are caulked to increase the diameter, and a string is passed through the short pipe hole. Hand 8 In the first embodiment, the lower ends of the holding plates 7, 7 are expanded downward and outward so that the opening of the cylindrical body is moved between the holding plates when the opening / closing tool for closing the mouth is turned. It is provided for easy guidance.

The opening / closing tool 4 may be formed as in the second embodiment shown in FIGS. In the second embodiment, as shown in FIG. 4 and FIG. 5, a locking pin 5 extends from one end of both holding plates 7, 7 hanging in parallel from the left and right side edges in the longitudinal direction of the narrow band-shaped top wall 6. Are projected outward, a recess 9 is formed in the inner surface portion of the holding plate having the retaining pin, and a through hole 10 is formed in the other retaining plate portion extending the central axis of the retaining pin.
The outer periphery of the recess is broken by driving a stopper pin, and the stopper pin 5 is inserted into the recess and the through hole.
Protrusions 11 and 11 are provided on the inner surfaces of both holding plates at the other end of the opening / closing tool. And the second
In the case of this embodiment, a part of the upper end of the cylindrical body 1 is inserted as a pinch-shaped portion 3 between the two holding plates on the side of the stop pin 5 and is pivotally mounted by driving the stop pin 5. At the upper end of the cylindrical body on the side to be closed, through holes 12, 12 are formed so that the projections 11, 11 can be engaged when the opening / closing tool is turned down and the upper end of the cylindrical body is inserted between the holding plates. By forming the opening / closing tool 4 as in the second embodiment, it is possible to easily pivotally attach the opening / closing tool 4 to the upper end of the cylindrical body.

As shown in FIGS. 1 and 3, when the opening / closing tool 4 is erected on the cylindrical body 1, the upper end portion of the cylindrical body coming out of the holding plates 7 forms a mouth portion 13. 15 and 16
Is a tube container and a toothbrush with a cap 17.

[0012]

According to the present invention, the main body of the bag is formed of a cylindrical body 1 made of an elastic synthetic resin. Since one end is inserted between the holding plates 7 and 7 and the portion is pivotally connected with the stopper pin 5, as the opening / closing tool 4 is turned by turning around the connecting portion, the insertion portion between the holding plates is moved. The mouth 13 formed by the upper end of the cylindrical body excluding is to be sequentially fed from the insertion portion side to between the two holding plates to be closed, and the opening of the mouth 13 is pulled up from the other end of the opening / closing tool and from the mouth 13. It can be automatically performed by elastic restoration as it comes off from both holding plate parts, so that its mouth can be opened and closed very easily and quickly.
