Description

[Detailed Description of the Invention] The present invention relates to a container for holding liquid such as water, a liquid container such as a urine collection device, and the like.

Conventionally, for example, in urine collection containers, a container made of glass is usually used, but it is dangerous and expensive because it can break, and since it does not have a lid, there is a risk of overflowing when carrying it. It was hot.

In addition, in order to prevent damage and reduce costs, when making a product that has an integrally molded plastic waist and an opening/closing lid, the cap for the lid (in this specification, even if it is not made of metal, it is made of 10-karat gold). The container is blow molded in one piece, but at this time, uneven thickness occurs, resulting in thinner parts and weakening, making it difficult to clean the inside of the container, and moreover, the price is high.

In this invention, the bag body and the cylindrical cap body with an opening/closing lid are manufactured separately, and the two are joined by a tapered surface, which eliminates the above-mentioned drawbacks of the conventional one and prevents liquid from overflowing during transportation. There is no fear of breakage, the bag is disposable and sanitary, and it is possible to provide a liquid container that is simple in structure, lightweight, and inexpensive.

In this invention, the films at the entrance of a plastic film bag are overlapped and bonded, leaving an opening, to form an opening narrower than the internal cross-sectional area, and the cross-sectional area of the opening increases from the entrance to the back. A hollow truncated cone-shaped cylindrical cap body, which is formed to gradually become smaller in size and has a separately manufactured lid that can be opened and closed at its wide diameter end, is fitted into the opening. This is a liquid container with special features.

To explain the present invention with reference to the drawings, FIG. 1 shows the material 2 of the bag 1 (see FIGS. 2 and 3), in which a film tube of synthetic resin such as polyethylene is cut and one end is cut. It is closed with a heating seam or the like to form the bottom 3, and the other end is left open.

The opening on this open side is closed in the direction of the arrow 4 and the opposite sides are brought into close contact to form a mating side 5 in a direction perpendicular to the line of the bottom 3.

Next, remove the film on the side of the mating side 5, leaving an opening 6.
The joints 7 and 8 are bonded together by heating to a depth of 100° C. to form an opening 6 having a narrower cross-sectional area than the inside.

At the joining part 7, the corners are folded back and joined four times for reinforcement.

In the joint 8, a hole 9 for a handle is provided.

The width b at the entrance of the opening 6 is larger than the width b2 at the rear end.

This state is shown in FIGS. 2, 3, and 4. FIG. 6 shows a state in which the opening 6 is expanded.

At this time, the opening 6 forms a tapered surface whose cross-sectional area gradually decreases from the entrance toward the back.

Preferably, the length of the opening 6 is greater than the diameter of the inlet.

FIG. 5 shows a truncated cone-shaped cylindrical base body 10 separately manufactured from plastic or metal, and the diameter d1 of the main entrance is smaller than the diameter of the lower end.

There is one or more notches 11 at the lower end.

12 is a lid that can seal the entrance;
3, it is connected to the base body 10.

There are protrusions 14 and grooves 15 on the inner surface of the inlet and on the outer surface of the lid 12, as shown in FIG. 7, to ensure that the lid 12 is tightly sealed.

In use, when the cap 10 is inserted into the opening 6 of the bag 1 and pushed in a little, the film in the opening 6 will be elastically deformed and fully adhere to the outer circumferential surface of the cap 10, preventing liquid from leaking. It is possible to combine them so that they do not occur.

At this time, if a ring comb-shaped ring comb packing 16 is wrapped around the outer peripheral surface of the cap body 10 before insertion, liquid leakage can be more completely prevented.

When liquid is put inside, it becomes a shape that can be placed stably on the floor as shown in Figure 8.

At this time, the joint portion 7 serves as reinforcement to support the base body 10.

When opening the liquid inside, the liquid collects on the step of the lower edge 17 of the cap body 10 and is difficult to flow out, but if the notch 11 is provided, the liquid will be guided by this and will flow out easily.

The position of the notch 11 is preferably such that it is on the lower side when draining the liquid.

Since the hole 9 that becomes the handle is generally on the upper side when pouring the liquid, a notch 11 is provided on the opposite side, that is, on the side of the joint 7.
It is a good idea to locate it.

Such liquid containers can also be used as containers for chemical solutions, containers for water, and the like.

In this invention, the films at the entrance of a plastic film bag are overlapped and bonded, leaving an opening, to form an opening narrower than the internal cross-sectional area.The cross-sectional area of the opening gradually increases from the entrance to the back. It was formed to be small and was manufactured separately.
A liquid container characterized in that a hollow truncated cone-shaped cylindrical cap body with a lid that can be opened and closed at one end with a wide diameter is fitted and attached to the opening; There is no overflow during transportation, there is no risk of damage, the manufacturing is extremely simple, the price is low, the bag can be disposable, it is hygienic, and the bag and cap are By making the bag body separate from the body, the bag body can be folded into a small size and stacked, and the cap body is also tapered, so the bag body can be stacked closely together with the lid open, making it easy to pack, transport, and store. It is possible to provide a liquid container that does not require space, the shape of the cap body can be changed depending on the application, and is easy to handle, which is extremely effective in terms of practical use.
