The present invention relates to temporary bulkheads for shipping containers.
Shipping containers are well known and are typically in the form of a large rectangular box made of strong materials such as, for example, corrugated steel, aluminum, and fiber-reinforced polymers. Access to the container may be provided by double doors which are hinged to one open end of the container. These types of shipping containers are used to ship all types of durable goods by all modes of transportation including truck, air, rail and ship. The containers are mostly identical in form so that they are easily stackable.
Solid form goods are easily loaded into and out of the shipping container through the double door access. Goods which exhibit fluidic characteristics when in bulk form (e.g., free flowing bulk grains, formed pellets as seen in certain animal feeds, loose flowing soils, minerals, ores and other substances of like flowable character) are also shipped in these containers but the loading and unloading process is a bit more difficult. As the flowable product is deposited into the container, something must be placed at the point of entry to prevent the material from flowing outside the container, particularly if the container is to be filled to capacity.
Temporary bulkheads for shipping containers have been proposed and may be seen in AU2007201346A1, for example.
In a first embodiment, the present invention provides 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.
The patent or application file contains at least one drawing executed in color. Copies of this patent or patent application publication with color drawing(s) will be provided by the Office upon request and payment of the necessary fee.
The above-mentioned and other features and advantages of this invention, and the manner of attaining them, will become apparent and be better understood by reference to the following description of the invention in conjunction with the accompanying drawing, wherein:

Ref no. 102—folded strengthening section at top of panel 101.
Ref no. 103—folded flap at bottom of panel 101.
Ref no. 104—optional, rigid strengthening board for removable insertion into opening created by folded strengthening section 102—board 104 may extend entire length of strengthening element 102, if desired.
Ref nos. 110A and 110B—identical temporary bulkheads for positioning in double door opening.
Ref no. 110A′—alternate embodiment of temporary bulkhead for single door opening.
Ref no. 112—center vertical crease line in temporary bulkhead 110A, 110B.
Ref no. 114—overlap of divided sections 102 at crease line 112 when temporary bulkhead 110A, 110B is in angled (about crease line 112), installed position.
Ref no. 116—foldable securing tab for securing strengthen section 102 which may form a triangular shape in cross section.
Ref no. 116a—open slot in panel 101 for passage of securing tab 116 which may then be folded at fold lines “F” to prevent unintentional withdrawal of tabs 116 from slots 116a.
Ref no. 118—opposite side edges of bulkhead panel 101 for removably securing bulkhead into vertical slot of shipping container side walls.
Ref no. 120—same as 118 except for frame opening.
It will be appreciated the bulkheads 110A, 110B, 110A′ may be packaged flat and assembled on site for compact packaging and ease of installation.
The dimensions of the bulkheads 110A, 110B and 110A′ may be selected according to the respective dimensions of the container or frame opening where they are to be installed.
A Double Door Embodiment may have one or more of the following in any combination:
1. A Temporary Bulkhead for a shipping container that collapses/folds into the opening of a container and locks into position through the designed shape of the material it is made from providing holding support to hold/lock the temporary bulkhead in place. This is achieved through notching creasing, folding and shape and rigidity of material.
2. The rigid inserts that are folded into the Temporary Bulkhead for a shipping container to provide extra strength when needed in the top folded section.
3. The use of layers of corrugated material laminated to provide greater rigidity for heavier flowable products.
4. The use of the triangle stiffening design at the top of the temporary bulkhead.
5. The double inward facing and outward facing angled flaps at the bottom of the temporary bulkhead.
6. The design is stackable due to the modular design to gain greater height to maximize capacity.
A Single Door Embodiment may have one or more of the following in any combination:
1. The single door design has the same profiles and use of laminated product as the double door.
2. The single door has a unique side section that acts as a spacer to allow the second door to close without destroying the top and bottom folded sections.
3. The design is stackable due to the modular design to gain greater height to maximize capacity.
4. The rigid inserts that are folded into the Temporary Bulkhead for a shipping container to provide extra strength when needed in the top folded section.
5. The use of the triangle stiffening design at the top of the temporary bulkhead.
Another embodiment of a seen in
Referring still to 16A and 16B, top edge 166 is seen to include locking tabs 170a and 17b each having a pair of ears 170a′ and 170b′ on either side thereof which are foldable toward each other to lie against a respective locking tab 170a, 170b while the user inserts the locking tabs 170a′, 170b′ into the locking tab slots 172a, 172b, respectively. The ears may undergo a further weakening process step during manufacture (e.g., cork crushing) so as to facilitate their folding and insertion through a respective locking tab slot. Prior to inserting the locking tabs the user folds the bulkhead along the upper-most fold lines FT (consisting of the three fold lines F1, F2 and F3) so as to form the strong triangle shape at the top of the bulkhead (see also
The single door embodiment of bulkhead as seen in
Referring to the upper edge detail in
With each side edge 162 and 164 secured in the manner described above, temporary bulkhead 160 provides a secure temporary bulkhead for loading of flowable product into the shipping container. If desired, a reinforcing panel RP may be glued or otherwise secured to the main panel of bulkhead 160, the line L indicating the upper edge thereof.
The bottom panel 168a may also include edge detail seen best in
More particularly, center lock CL is formed by panels 200a and 200b being separated from each other at midline ML from fold line Fa to fold line Fc, and crease lines 300a and 300b being formed at an angle from fold line Fb to fold line Fc. Triangular sections 300a′ and 300b′ are formed which may fold along their respective crease lines when folding panels 200a and 200b toward each other. The base of each triangle section is cut from the panel at 300a″ and 300b″, this allowing the triangular sections to bend away from the respective panel when a force is applied thereto during folding of the panels toward each other as seen in
Panel 200a includes a side edge 202, bottom edge 206a and top edge 208a which are of the same configuration as respective side edge 204, bottom edge 206b and top edge 208b of panel 200b. Upper fold lines Fa, Fb and Fc traverse along panels 200a and 200b in parallel, spaced relation to each other and to top edges 208a and 208b which themselves extend collinear to each other when in the unfolded condition.
Top edge 208a includes locking tabs 208a′ and 208a″ each having a pair of respective foldable ears for folding and inserting though respective locking tab slots SL1 and SL2 when manipulating bulkhead 200 into the folded condition to ready for installation to a shipping container SC. Likewise, top edge 208b includes locking tabs 208b′ and 208b″ each having a pair of respective foldable ears for folding and inserting though respective locking tab slots SL3 and SL4 when manipulating bulkhead 200 into the folded condition by folding along lines Fa, Fb and Fc to ready bulkhead 200 for installation to a shipping container SC as seen in
Edges 202a and 204a extend at an inward facing obtuse angle a1 with their respective side edges 202 and 204. Edges 202a and 204a further form an outward facing acute angle a2 with respective side edges 202b and 204b. Edges 202b and 204c form an obtuse angle a3 with respective side edges 202c and 204c. Upon folding a wedge portion 204d is formed which provides added strength against outward forces bearing against bulkhead 200 from product loaded into shipping container SC. An identical wedge portion is formed at panel 200a by edges 202a and 202b (
The double door embodiment of bulkhead 200 as seen in
Referring to the upper edge detail in
With each side edge 162 and 164 secured in the manner described above, temporary bulkhead 160 provides a secure temporary bulkhead for loading of flowable product into the shipping container.
The bottom edges 206a and 206b may also include edge detail seen best in
While this method and apparatus has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as described.
