TEMPORARY BULKHEAD FOR SHIPPING CONTAINER

Abstract

A double door temporary bulkhead locking member comprising a single or joined rigid material with the angle apex pointing inward. The temporary bulkhead is wedged across the width of the inside opening of a container. When the flowable product is installed into the container the pressure on the bulkhead is transferred to the outer edges sealing the product into the container. The temporary bulkhead material has a series of creases, notches, slots and shapes that are folded and locked into the proprietary shape. A single door bulkhead locking member comprising a single or joined rigid material as a straight plain panel to fit into the single doorway of a shipping container. The temporary bulkhead is wedged across the width of the inside opening of a container when one door is closed and the other open. When the flowable product is installed into the container the pressure on the bulkhead is transferred to the outer edges sealing the product into the container. The temporary bulkhead material has a series of creases, notches, slots and shapes that are folded and locked into the proprietary shape.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0040] FIG. 1A-1 is the main upright rigid material of the temporary bulkhead made to various heights for the given flowable product.

[0041] Reference number 2 is the creased and folded profile of the top of the temporary bulkhead as seen in FIGS. 1B, 2A, 2B, and 2C.

[0042] FIG. 1B reference number 3 is the bottom extra support/hold-down flaps that are attached to the bottom of the inside panel where the flowable product is placed against the temporary bulkhead. (see FIG. 2C).

[0043] FIG. 2C and enlarged call-out drawing is the strengthening section substrate 4 used where added strength is required. These are located is each folded section on both sides of the center vertical crease.

[0044] FIG. 4 is a perspective drawing of the circled section on FIG. 2B. The design here is such that the angled creases fold down and when the temporary bulkhead is collapsed/folded into the container opening they act as buffer stoppers to stop the temporary bulkhead from folding any further, thus locking/holding the bulkhead in place in the container.

[0045] FIG. 5A is a perspective view of the installed temporary bulkhead invention wedged into the single open doorway of the container in the intended manner with one hinged container doors closed and the other open.

[0046] FIG. 5B is a top view showing the installed position of the temporary bulkhead invention of FIG. 5A in the single open doorway of the shipping container.

[0047] Attention is turned to further preferred embodiments. A single temporary bulkhead 110A is seen in FIG. 7A and is the main upright rigid material for removably securing in a double door container opening and may be made to various heights for the given flowable product. Two identical temporary bulkheads 110A and 110B are seen in FIGS. 14 and 15 with bulkhead 110B stacked upon bulkhead 110A. Any number of bulkheads may be stacked in this manner to achieve the desired height in the container opening.

[0048] Reference numeral 102 shows the creased and folded profile of the top of the temporary bulkhead.

[0049] Reference numeral 103 is the bottom extra support/hold-down flaps that are attached to the bottom of the inside panel 101 where the flowable product is placed against the temporary bulkhead.

[0050] FIG. 8C and enlarged call-out drawing shows the strengthening section substrate 104 used where added strength is required. Rigid rectangular, elongated panels 104 may be inserted into each folded section 102 on both sides of the center vertical crease 112.

[0051] FIG. 10 best shows the angled creases fold down 114 and when the temporary bulkhead is collapsed/folded into the container opening they act as buffer stoppers to stop the temporary bulkhead from folding any further, thus locking/holding the bulkhead in place in the container.

[0052] FIG. 11A is a perspective view of a version 110A of the installed temporary bulkhead invention (110A is essentially one half of a double bulkhead 110Awith no need for center crease 112) wedged into the single open doorway of the container in the intended manner with one hinged container doors closed and the other open.

[0053] FIG. 11B is a top view showing the installed position of the temporary bulkhead invention of FIG. 11A in the single open doorway of the shipping container.
