DETAILED DESCRIPTION OF THE INVENTION

The improved shipping container of the present invention is indicated generally at 1, and is shown in a sealed closed position in FIG. 2, and in an exploded perspective condition in FIG. 1. Container 1 includes an outer housing indicated generally at 3, preferably having a parellelopiped configuration with four spaced parallel side walls 5 which provide an open top 6 and which define a hollow internal storage chamber 7. A plurality of closure flaps 9 preferably are formed integrally with the upper edges of side walls 5 and are adapted to be placed in an overlapping relationship when closing the open top 6 of outer housing 3 as shown in FIGS. 2 and 3. After the pairs of opposed flaps 9 are placed in the overlapping closed relationship with their outer edges 9A being in abutting relationship, the outer housing is sealed by an H-configured taping arrangement consisting of two strips 11 which extend along the junction of the two topmost pair of flaps 9 and their respective side walls 5 after a cross strip 13 extends over and secures the abutted edges of the top two closure flaps in a secure closed position for subsequent shipment (FIG. 2). The bottom of outer housing 3 preferably will be initially opened and secured with similar closure flaps 15 as shown in FIG. 3, and sealed in some manner such as with tape or adhesives. Outer housing 3 preferably is formed of a fiberboard material, preferably a double-walled corrugated fiberboard material, which provides sufficient strength and rigidity to container 1 and complies with the required Federal regulations for shipping hazardous materials such as batteries. In the preferred embodiment, walls 5 and flaps 9 will have a thickness of approximately ¼ inch although this thickness can vary within the concept of the present invention.

Referring to FIG. 1, a plastic liner 17 preferably formed of polyethylene with a thickness of approximately 3 mils, is placed within internal storage chamber 7 forming an interior liner which generally conforms to the shape and size of storage chamber 7.

In accordance with one of the features of the invention, a plurality of dividers indicated at 19, 21 and 23 are placed in a vertical stacked tiered relationship within plastic liner 17 and interior storage chamber 7 as shown in FIG. 3, and are separated by individual planar partitions 25. Partitions 25 preferably are formed of the same fiberboard or cardboard material as housing 3. Dividers 19, 21 and 23 may be of the type shown in U.S. Pat. No. 6,227,370 or have other constructions, and form a plurality of individual storage compartments 27, 29 and 31 respectively, within each of the dividers for receiving individual batteries 33, 35 and 37 therein as shown in FIGS. 1 and 3. The dividers which preferably are formed of an inexpensive cardboard material, have different heights and number of individual storage compartments to accommodated different size batteries as shown in FIG. 3. The individual compartments 27, 29 and 31 are sized to accommodate various size batteries commonly used in many electrical appliances and apparatus. For example, compartments 27 are sized to receive usual 9 volt electrical lantern-size batteries, with compartments 29 be sized to receive the usual D-sized batteries, with compartments 31 being sized to receive the smaller AA and AAA size batteries. However, the sizes of these individuals compartments can very without affecting the concept of the invention but have been found to accommodate the majority of the common-size batteries used for most electrical appliances and apparatus.

Each divider 19, 21 and 23 have open tops and bottoms which are closed by partition members 25 which serve as the support for the batteries located above as shown in FIG. 3. Preferably, a topmost partition 25 is placed on the open top of top divider 23 to prevent the batteries 37 stored therein from falling out of the compartments if the container is turned upside down.

As shown in FIG. 3, after the individual compartments of the dividers are filled with batteries and are separated by partitions 25, a top partition 25 preferably is placed on the top of divider 23 to close the open tops of the individual storage compartments. The top of plastic liner 17 is then closed and secured by a closure member 39 which secures the topmost partition 25 tightly against the top edges of uppermost divider 23.

In accordance with one of the features of the invention, the particular heights of dividers 19, 21 and 23 are such so that dividers 21 and 23 when combined together with an intervening partition 25, has a height generally equal to the height of large divider 19. Likewise, the height of smaller divider 23 is slightly less than ⅓ the height of divider 19 so that three of the smaller dividers 23 can be used in place of a single divider 19 together with intervening partitions 25 and substantially fill chamber 7 of outer housing 3. Likewise, a pair of large dividers 19 can be used with an intervening partition 25 to substantially fill interior storage chamber 7 of housing 3. Other combinations of the dividers can be used, all of which will enable the dividers to nearly fill internal storage chamber 7 when combined with the thickness of one or more partitions 25 providing for a compact and stable arrangement of the dividers and intervening partitions avoiding a large access space between the topmost partition 25 and the closure flaps. The sum of the vertical height of the stacked dividers together with the thickness of the partitions, substantially equal the internal vertical height of storage chamber 7. As an example, divider 19 may have a height of approximately 6 inches, divider 21 may have a height of approximately 4 inches, and divider 23 may have a height of approximately 1½ inches.

As can be seen in FIG. 4, each of the batteries will be located within a separate compartment and completely isolated from horizontally adjacent batteries as well as vertically adjacent batteries by the intervening walls of the dividers and partitions 25. Plastic liner 17 prevents exterior moisture from affecting the batteries stored in the housing as well as retaining any leakage acid from the batteries from seeping through outer housing walls 5. Liner 17 also prevents any of the stored batteries from being exposed to walls 5 if dislodged from their individual storage compartments.

In summary, the improved shipping container of the present invention provides a container having a substantially rigid outer housing formed of a corrugated fiberboard material with an interior plastic liner which will contain a plurality of different size dividers, which when stacked in a vertical tiered relationship and separated by partitions, form a plurality of individual storage compartments of various sizes, depending upon the particular divider or dividers placed within the storage container, for individually holding various size batteries for shipment, which batteries are prevented from contacting adjacent batteries even should the shipping container be moved to various positions, even in an upside down position.

It is understood that housing 3 can have other configurations than that shown in the drawings and discussed above without affecting the concept of the invention, with the configurations of the partitions and dividers being complementary to the housing and plastic liner.

In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed.

Moreover, the description and illustration of the invention is an example and the invention is not limited to the exact details shown or described.
