This invention relates to a container of variable volume for the transport and storage of loose flowable material such as liquids, granular materials, and the like.
It is an object of the invention to provide improved variable volume containers.
It is a particular object of the invention to provide a container defined by a flexible lining which can be adjusted between expanded and collapsed positions to vary the volume of the container.
It is a further object of the invention to provide an improved linkage in the container to expand and contract the lining between large volume changes.
According to the invention, the expansible and contractable container comprises a rigid container having an open mouth, and a rigid frame spaced from the container and facing the open mouth. A flexible cover is provided which is coupled to the frame and the container and defines therewith a closed enclosure or envelope. The flexible cover is adapted to permit relative movement between the container and the frame to vary the volume of the enclosure. In further accordance with the invention, there is provided linkage means coupled to the frame and the container for moving the container and the frame relative to one another. The linkage means is located in a plane positioned between the rigid container and the flexible cover and is enclosed along with the flexible cover by the rigid container when the latter is collapsed towards the frame. The linkage means comprises a lazy tongs linkage which is coupled to the frame and the rigid container.
The objects and features of the invention will become apparent from a consideration of the accompanying drawing, wherein preferred embodiments of a container with variable volume according to the invention have been illustrated only by way of example.
In the drawings:
FIG. 1 is a sectional view of a container of variable volume shown in an expanded state.
FIG. 2 shows the container of FIG. 1 in a collapsed state.
FIG. 3 shows in section another embodiment of the container in a collapsed state.
The container is constituted by an envelope or flexible liner 1 of a flexible material.
The envelope 1 is closed at the bottom thereof by a plate member 3 of rigid material and preferably provided with feet 4.
This envelope 1 is secured at the top thereof to a plate member 5 of a rigid material, constituting a cover for the flexible material. The member 5 is provided with a filler 6 for the introduction of material into the container. The member 5 is extended downward on all sides thereof, by wall members 7 of rigid material, a suitable height in such a way as to form together with the member 5 an open mouth enclosure. Frames 2, preferably of hoop shape surround the envelope i1 and are collapsible onto one another as shown in FIG. 2 when the links 8 (to be discussed more fully hereinafter) are collapsed.
The walls of envelope 1, are of a flexible material, to permit contraction of the envelope from the position of maximum extension as shown in FIG. 1. Upon contraction of the envelope the spacing of the frames 2' is diminished, until they contact one another when the enused for the purpose of varying the volume of'the container. H
In the embodiment shown, there is provided linkage means comprising a system of links 8, which are hingeably connected to each other by pins to form a lazy tongs linkage. Pins 25, 25', 25 connect the links together and join the linkage to the frames 2 such that, ,by exerting a force on said linkage by meansof handwheel 9,,it is possible to expand and contract the walls of the deformable envelope 1 and to cause the frames to accordingly move relative to one another. The handwheel is connected to a threaded member 22 on which is mounted a traveling nut 23'. The upper end of the linkage is pivotally connected to the traveling nut 23 so that when the handle 9 is turned in opposite directions the linkage is expanded and contracted in accordance with the travel of the nut. Traveling nuts on a threaded member which is adapted to rotate are well known and an example of such a construction are the elements 148, in US. Patent 3,054,- 310.
In this embodiment, four systems of articulated rods are preferably provided, said rod systems being arranged in the middle part of each container side.
It is to be understood that an outlet opening can be provided in the bottom of the envelope to allow outflow of material from the envelope.
With reference to the embodiment in FIGURE 3, the container is constituted by an upper part of rigid material consisting of a plate member 15 and rigid wall member 17. The envelope 11 of flexible material is secured to the inside of member 15. The envelope 1 1 is connected at the bottom thereof to a rigid plate member 13, by screw bolts 20.
In this embodiment, the volume adjustment of the container is permitted by members 18, that are slidably connected to one another and adapted for internesting one within the other as shown in FIG. 3 in the collapsed state of the envelope.
The deformable envelope 11 can be made in the same way as in the example according to FIGS. 1 and 2, that is, open at its top and secured by means of its upper and lower edges to the cover 15 and rigid bottom *13, respectively or it can be entirely closed as shown in FIG. 3 and fastened through screw bolts, and the like, by means of its upper or lower part to the cover 15 and the rigid bottom 13, respectively. FIG. 3, the outwardly projecting horizontal members of the elements 18 substitute for frames 2 of the first embodiment and are hinged to the articulation points 25, 25', 2.5" and etc., of the lazy tongs linkage.
The container is shown with a supporting base 14 for the bottom 13. A filter 16 in the cover 15 permits the introduction of material into the envelope and numeral 19 represents an outlet opening in the bottom 13.
2. A container as claimed in claim -1 wherein said elements located between the plate members are of identical hoop shape and surround the lining.
3. A container as claimed in claim 1 wherein said elements located between the plate members are interconnected, slidably supported members of L shaped .cross section which are adapted to internest with one another when the framework is collapsed.
4. A container as claimed in claim 1 comprising means associated with the framework and extending externally of the container for collapsing and expanding the framework.
