Description

[Detailed description of the invention] Containers for storing liquids and related improvements The present invention relates to containers for storing liquids, particularly for storing different liquids alternately or simultaneously. Concerning containers for storage.

Current containers can be used to store liquids consisting of other different liquids. It is often not possible to store it. This is because the container is contaminated with the initial liquid.

The present invention provides a relatively rigid outer housing member and a relatively flexible inner housing member. The side housing member allows storage of different liquids alternately or simultaneously without making a mess. a first inlet/outlet is provided for the inner housing member; and a second inlet/outlet is provided for the outer housing member, both inlets/outlets. a port is located in the outer housing member and a first inlet/outlet opening is located in the outer housing member; for filling the container with liquid or removing liquid from the inner housing member. has a relatively larger cross-sectional area than the cross-sectional area of the opening of the means for accommodating.

Such containers can store two different liquids alternately or simultaneously without making a mess. . because the first liquid is in the outer housing member and in the inner housing member. can be stored on the outside and a second liquid can be stored within the inner housing member. It is. Additionally, the inner housing member of such containers stores large amounts of liquid. Must be used when working or filling liquid inside the housing There is no buildup of excessive pressure within the container while removing liquid from the component, because air , a first inlet/outlet and a first inlet/outlet for filling the container with liquid or from an inner housing member. means for removing or exiting the inner housing from between the openings and / Because it is possible to enter.

The second inlet/outlet opening is used to fill the container with liquid or to open the outer housing part. relatively larger than the cross-sectional area of the opening of the means for removing liquid from the material. Preferably, the outer housing member has a large cross-sectional area. or the buildup of excessive pressure during emptying is prevented.

a hole in the outer housing member, opposite the second inlet/outlet with respect to the first inlet/outlet; It is appropriate to provide a According to this hole, the container can be filled or emptied. while creating a pressure build-up in the container on the opposite side of the second outlet/outlet with respect to the first outlet/outlet. storing liquid in the outer housing member outside of the inner housing member without causing Can be done.

When fully inflated, the end of the inner housing member will meet the outer housing member. It is preferably substantially the same size and shape as the distal end, and is sufficiently constricted. The inner housing member is adjacent to the base, top, or one side of the outer housing member. It is appropriate to locate the

The inner housing member is connected to the outer housing for storing a combination of two liquids. It can only be partially inflated within the plug.

For convenience, while filling the inner housing member with one liquid, the outer housing member (obviously the opposite is also possible). ).

The inner housing member is connected to the outer housing member to provide a good connection at the first inlet/outlet. Preferably, sealing is ensured.

Such containers are particularly suitable for use on road tankers or ships.

The invention will now be described by way of example with reference to the accompanying figures.

In the drawing, FIG. 1 shows a container according to the invention with the inner housing member fully inflated; Figure 2 is a side view of the first housing member with the inner housing member fully deflated; FIG. 3 is a side view of the container shown in FIG. 3, and FIG. 2 is a side view of the container of FIG. 1 in a deflated state; FIG.

Figures 1 to 3 show containers for storing two different liquids alternately or simultaneously. A container 10 is shown.

The container lO includes a relatively rigid outer housing member 12 and an outer housing member 12 at a point 15. a relatively flexible inner housing member 14 coupled to the housing member 12; Become. The inner member 14 has an inlet/outlet for filling/removing the initial liquid. The outer member 12 has a port 16 for filling/removing a second liquid. It has a separate inlet/outlet 18. The inlet/outlet 16 and the outlet/outlet 18 contain liquids. (not shown) used for filling or discharging designed to have a relatively larger cross-sectional area than the cross-sectional area of the opening of the means ing.

Air holes 19 are provided in the outer housing member at the inlet/outlet I of the inner housing member 14. 6 on the opposite side of the outer housing member 12 from the inlet/outlet 18 .

FIG. 1 shows the container 10 with the inner housing member 14 fully inflated. , and whose distal end is substantially the same size and shape as the distal end of outer housing member 12. is shown. The distal end of the inner member 14 is smaller in size and shape than the distal end of the outer member 12. It is desirable to make it slightly larger to reduce stress on the inner member 14.

In this particular arrangement, the first liquid A is transferred to the inner member 14. (3) can be stored inside.

FIG. 2 shows the container 10 with the inner housing member 14 fully collapsed and the container 10 fully collapsed. It is shown ready adjacent the top of vessel 10. In this particular arrangement, the A second liquid B can be stored within the outer member 12 but outside the inner member 14. Ru.

In this way, two different liquids can be stored alternately without contaminating the container 10. Ru.

3, container 10 is shown with inner housing member 14 partially inflated/collapsed. The combination of two liquids A and B is thereby It can be stored at the same time without getting dirty.

When filling the outer member 12 via the inlet/outlet 18, air enters the inner housing portion. material 14 and the wall of the container opposite the inlet/outlet 18, exiting the container between the mouth 18 and the opening of the means used to fill the container; I can't do it.

The holes 19 release the trapped air and thus eliminate the build-up of pressure that occurs during the filling operation. To prevent.

The inner member I4 of the container 10 is filled with liquid A via the inlet 16 while simultaneously filling the inner member I4 with liquid B. Conveniently, it is removed from the outer member 12 of the container via the outlet 18. pair is also possible).

Inner housing member 14 is formed from a highly flexible material with high breaking strength. is desirable, so that when only the outer member is used to store liquid, the inner The housing member easily collapses and occupies a very small volume adjacent the top of the container 10. Not only that, but there is no risk of destruction (it can also support large volumes of liquid).

If only the outer housing member 12 is to be used, some liquid may leak inside. If it remains in the housing member 14, a better sealing of the inlet/outlet 16 will be achieved. be exposed. However, when pressure filling via the population/outlet loe 8, the inlet/outlet 16 tends to be empty (and vice versa).

Several containers 10 may be used as compartments in an oil tanker, for example, and the oil may be removed on the outbound journey. on the return journey, e.g. water or liquid fertilizer. . In such applications, the flexible inner housing member 14 may be made of a petroleum product resistant material. Container 10 will have to be made of two kinds of liquids, using it as a road tanker. or transport one liquid on the outbound trip and another on the return trip. It can also carry two liquids.
