DESCRIPTION:
BRIEF SUMMARY
This invention relates to a base for a container whereby the flowable contents of the container can be discharged.
It is a requirement of many containers that the contents be readily bottom discharged by gravity. Such containers are particularly useful for the carriage of bulk dry materials of a discrete nature. To this time, devices have been provided which allow side discharge through a side of the container and bottom discharge through a funnel in the base of the container or attached thereto.
This invention provides a container base (hereinafter for convenience called a base) which has many advantages over known arrangements for the discharge of flowable materials from containers. Generally, the base includes a four sided base frame defining an opening and a pivotally connected base bottom which can be pivoted relative to the base frame as required to cover and uncover the opening. In a preferred embodiment there are flaps connected to the base frame which deploy as the base bottom pivots with respect to the base frame to provide directional control of the discharge of material from the container of which the base forms part.
The base may be for or form part of a container which is preferably but not necessarily of the type which comprises four interconnectable wall panels which can be mounted on and removed from the base in a simple manner. This form of container because of its collapsible nature has great attraction as a container for repeated use in the transport of material from a place of manufacture to a place of use where the contents can be readily discharged through the container base.
Broadly, the invention can be said to provide a container base for or forming part of a container, where the base includes a rectangular base frame with four sides defining an opening through the base frame, a base bottom which is pivotally connected to the base frame at or closely adjacent one side thereof and latch means to releaseably retain the base bottom in covering relationship with the opening through the base frame.
Preferred embodiments of the various features of the invention will now be described with reference to the accompanying drawings in which:
FIG. 1 is an exploded schematic perspective view of one form of a container base according to the invention with associated wall panels of an enclosure for coupling to the base,
FIG. 2 is a an exploded enlarged view of another form of the container base of the invention,
FIG. 3 is a fragmentary sectioned view on the section line 3--3 of FIG. 2 as it would appear when the components of the container base are secured together,
FIG. 4 is a schematic side view of the base of the invention as shown in FIG. 2 with enclosure forming wall panels coupled to it to make a container and with the base closed,
FIG. 5 is a view similar to FIG. 4 with the base in the open condition,
FIG. 6 is a front view of the container of FIG. 4,
FIG. 7 is a top view of the container of FIG. 6 showing some possible shapes for discharge flow diverter flaps, if fitted,
FIG. 8 is a front view of the container of FIG. 7 showing discharge flow diverter flap positioning when the base is in the open condition,
FIG. 9 is a top view of the container in the FIG. 8 condition,
FIG. 10 is a top view of a container in the FIG. 4 condition showing another form of discharge flow diverter flap,
FIG. 11 is a front view of a container as shown in FIG. 10 with the base bottom open showing the disposition of the discharge flow diverter flap,
FIG. 12 is a schematic side elevation of a container in a device to facilitate use of the base of this invention,
FIG. 13 is a view similar to FIG. 12 but with the container base in the open condition, and
FIG. 14 is a is a schematic perspective view of another form of device to facilitate use of the base of this invention,
As shown in FIGS. 1 and 2 the container base 1 includes a base bottom in the form of a pallet 1a comprising three bearings 4 and upper battens 18 covered by a cover sheet 2 and there is a hole 3 in each of the outer pallet bearers 4. The container
