Definitions
- the present invention concerns nestable or stackable containers. More particularly, the invention is directed to a spacer for nestable containers or vessels.
- Nestable containers made of plastic or impregnated or coated paper have found wide commercial use. For economical storage and shipment and convenience of handling, such containers are often made with tapered sides and are stored or shipped in a stacked arrangement. Ideally an individual container should be readily separated from the next adjacent container in the stack without the use of much force and, in some situations, merely by the pull of gravity against the weight of the container next in line for removal from the stack.
- nested tapered containers tend to become telescopically wedged together, particularly when more than two are stacked so that there is a lot of weight on the bottom containers. Further, nested containers tend to resist ready separation because of a relatively airtight seal, which causes vacuum lock, formed between adjacent nested containers. Such a seal tends to prevent the admission of air between adjacent containers, thus hindering separation.
- the present invention is directed to a spacer for preventing jamming or vacuum lock between adjacent nested containers.
- the spacer can be shaped to match the curvature of the nested containers, or laid flat if the container is rectangular.
- Each spacer has upper and lower abutment surfaces which serve to prevent airlock between adjacent nested containers placed in a vertical stack.
- a living hinge formed approximately centrally of the spacer allow for conformance to a container or vessel with a wide range of curvatures.
- An adhesive is used to secure the spacer to the sidewall of the container.
- the arrangement involves the use of a spacer.
- the spacer is configured to fit between adjacent nested containers to keep a sufficient amount of space between adjacent top ends of the container to prevent the formation of a tight seal between the containers.
- a living hinge arrangement allows the spacer to bend so as to conform to virtually shape of container.
- the spacers are available as an aftermarket device and so can be retro-fitted to virtually any type of nestable container. The spacers are held in position by a small amount of adhesive.

- the device 10 which is essentially a spacing element or spacer 10 has a generally curved or arcuate shape corresponding to the curved upper edge of the sidewall of 14 a nesting cylindrical container.
- the spacer 10 is essentially a curved rectangle having upper 20 and lower 22 abutment surfaces which serve to provide a weight bearing support surface when the spacer 10 is positioned between containers.
- the arcuate shape of the device 10 is due to the fact that it is intended to be used with a cylindrical container having a circular top opening. If the device 10 is to be used with rectangular containers it would of course be flat, but the functionality would be unchanged as will be explained below.
- the device 10 has a unitary construction and thus can be formed using injection molding or similar technique.
- the device 10 is preferably formed from a high strength rigid plastic or polymer, but any sufficiently strong, rigid material will be effective. While the device 10 is rigid, it is important that compressing the device 10 in the vertical direction (from top to bottom) be made especially difficult as it is essentially the vertical spacing between containers 24 that is being limited by the device 10 and method of the invention.
- a lattice of support members 26 , 28 are molded into the device 10 .
- Horizontal support members 26 extend laterally from side to side of the device 10 while regularly spaced vertical members 28 extend from the upper 20 to the lower 22 abutment surfaces.
- the abutment surface 20 engages the lower 23 surface of the annular flange 27 positioned about the opening of most cylindrical containers 24 .
- the device 10 is placed in this position to allow the container 24 to be nested into position within a lower container 24 , but prevents full insertion of one container 24 into another.
- Lower abutment surface 22 engages the upper edge 29 of the lower container 24 and serves to prevent the full insertion of the upper 24 container into the adjacent lower container 24 , thereby avoiding vacuum lock or air lock.
- the device 10 will still be effective even if the container 24 has no flange 27 as the lower abutment surface 22 will come into contact with the top edge 29 of the lower container 24 in a stack of nested containers 24 as will be explained in more detail later.
- Both the horizontal 26 and vertical 28 members extend from the front 30 to the rear face 32 of the device 10 .
- the vertical members 28 help prevent compression of the device 10 from top to bottom, and this action is greatly aided by horizontal support members 26 as the two form a lattice which strengthens the device 10 against compression in either direction.
- the use of the lattice structure allows the device 10 to be nearly as strong as a solid block of material but with greatly reduced cost and weight.
- a centrally positioned indicia panel 34 is formed in the front face 30 of the device, the panel providing space for positioning a product logo or instructional information about the device 10 , the indicia panel 34 useful as a push tab when applying the device 10 to a container.
- a recess 38 is formed in the rear face of the device 10 , which recess terminates at panel 34 , the recess 38 including sidewall 40 .
- Sidewall 40 , support members 26 , 28 , and panel 34 are all of the same thickness so that during manufacture the cooling or curing time for all portions of the device 10 are the same, thereby reducing manufacturing cost and time.
- the device 10 as shown is designed to be used “aftermarket” with any containers 24 the user may have provided.
- the device 10 may also be reused and positioned on another container 24 . Again, nestable containers 24 with flat sides can be accommodated by making the device 10 flat. While larger containers 24 will of course typically have a larger radius of curvature than smaller containers the device 10 may be designed with a curvature corresponding to a large sized (5 gallon) bucket which would allow it to be effective with containers in the 1 to 5 gallon range, depending of course upon the height of the cylindrical vessel (as height affects curvature for any given volume).
- the device 10 is supplied with adhesive material 50 positioned on the rear face 32 of the device 10 so that a device 10 not matching the curvature of the intended container 24 will stay in position even though not perfectly flush mounted by way of adhesive 50 .
- the adhesive 50 may be of the peel and stick type.
- the device 10 could use a suction cup arrangement or other mechanical means to ensure the device 10 remains in position, which would increase the complexity and cost of the device 10 but allow for it to be reused indefinitely. Using adhesive 50 allows for the device 10 to be reused once or twice, which is sufficient since the device 10 would be used for the life of the container 24 .
- the devices 10 may also be made to exactly match the curvature of standard sized containers 24 , or sold in packs having a range of curvatures.
- the device 10 may be made flat so that nestable containers having flat sides (i.e., having a rectangular profile as in, for example, certain wastebaskets). In this case the radius of curvature of the device 10 would be zero.
- the device 10 is positioned on the top edge of a nestable container 24 in the position as shown in FIG. 5 . If the container 24 has a flange 27 the device 10 is positioned just under the flange 27 . Otherwise, the device 10 is positioned at the top edge of the container 24 with care being taken to ensure that the upper abutment surface 20 is at least slightly below the top edge of the container 24 .
- Adhesive 50 or other means for fixing the position of the device 10 are used to insure that the device 10 remains in the effective position as shown. Preferably a peel and stick type adhesive is used, this type of adhesive allowing for re-use of the device 10 as discussed above.

Abstract
An improved nestable container arrangement. The arrangement involves the use of a spacer. The spacer is configured to fit between adjacent nested containers to keep a sufficient amount of space between adjacent top ends of the container to prevent the formation of a tight seal between the containers. The spacers are available as an aftermarket device and so can be retro-fitted to virtually any type of nestable containers. The radius of curvature of the spacer is adjustable. The spacers are held in position by a small amount of adhesive.
Description
- The present invention concerns nestable or stackable containers. More particularly, the invention is directed to a spacer for nestable containers or vessels.
- Nestable containers made of plastic or impregnated or coated paper, have found wide commercial use. For economical storage and shipment and convenience of handling, such containers are often made with tapered sides and are stored or shipped in a stacked arrangement. Ideally an individual container should be readily separated from the next adjacent container in the stack without the use of much force and, in some situations, merely by the pull of gravity against the weight of the container next in line for removal from the stack.
- A common drawback of nested tapered containers is that they tend to become telescopically wedged together, particularly when more than two are stacked so that there is a lot of weight on the bottom containers. Further, nested containers tend to resist ready separation because of a relatively airtight seal, which causes vacuum lock, formed between adjacent nested containers. Such a seal tends to prevent the admission of air between adjacent containers, thus hindering separation.
- Attempts to solve the problem generally employ regularly spaced protrusions about the periphery of the top of the container where the airtight seal tends to form. Typical of these arrangements is U.S. Pat. No. 3,484,018 which has a series of annularly spaced projections formed into the upper rim of the bucket to deform the upper portion of a nested bucket to prevent airlock. While this patent may show a new method of solving the airlock problem, it involves the modification of the container itself to perform its function. The present invention and method involves the use of a removable spacer so that any existing container can be retrofitted to avoid the above mentioned stacking problem.
- The present invention is directed to a spacer for preventing jamming or vacuum lock between adjacent nested containers. The spacer can be shaped to match the curvature of the nested containers, or laid flat if the container is rectangular. Each spacer has upper and lower abutment surfaces which serve to prevent airlock between adjacent nested containers placed in a vertical stack. A living hinge formed approximately centrally of the spacer allow for conformance to a container or vessel with a wide range of curvatures. An adhesive is used to secure the spacer to the sidewall of the container.
- It is a major object of the invention to provide an improved nestable container arrangement. The arrangement involves the use of a spacer. The spacer is configured to fit between adjacent nested containers to keep a sufficient amount of space between adjacent top ends of the container to prevent the formation of a tight seal between the containers. A living hinge arrangement allows the spacer to bend so as to conform to virtually shape of container. The spacers are available as an aftermarket device and so can be retro-fitted to virtually any type of nestable container. The spacers are held in position by a small amount of adhesive.
- It is another object of the invention to provide an improved nestable container arrangement employing a small spacer to prevent vacuum lock of nested containers.
- It is another object of the invention to provide an improved nestable container arrangement having a removable small spacing element.
- It is a major object of the invention to provide an improved nestable container arrangement where a removable small spacer may be applied to buckets in a range of sizes.
- It is another object of the invention to provide an improved nestable container arrangement having a removable small spacing element which can be adhesively but removably applied to containers in a range of sizes.
- It is another object of the invention to provide an improved nestable container spacer which can be adjusted to conform to a range of curvatures.
- Finally, it is a general goal of the invention to provide improved elements and arrangements thereof in an apparatus for the purposes described which is dependable and fully effective in accomplishing its intended purposes.
- These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings.
- The present invention meets or exceeds all the above objects and goals. Upon further study of the specification and appended claims, further objects and advantages of this invention will become apparent to those skilled in the art.
- Various other objects, features, and attendant advantages of the present invention will become more fully appreciated as the same becomes better understood when considered with the accompanying drawings, in which like reference characters designate the same or similar parts throughout the several views, and wherein:

FIG. 6B is a representation of the underside of the alternative embodiment illustrating the application of the device. - Referring now to
FIGS. 1-5 the device of the invention, generally indicated by thenumeral 10 is shown. It can be seen that thedevice 10, which is essentially a spacing element orspacer 10 has a generally curved or arcuate shape corresponding to the curved upper edge of the sidewall of 14 a nesting cylindrical container. As shown, thespacer 10 is essentially a curved rectangle having upper 20 and lower 22 abutment surfaces which serve to provide a weight bearing support surface when thespacer 10 is positioned between containers. It should be noted that the arcuate shape of thedevice 10 is due to the fact that it is intended to be used with a cylindrical container having a circular top opening. If thedevice 10 is to be used with rectangular containers it would of course be flat, but the functionality would be unchanged as will be explained below. - As can be seen, the
device 10 has a unitary construction and thus can be formed using injection molding or similar technique. Thedevice 10 is preferably formed from a high strength rigid plastic or polymer, but any sufficiently strong, rigid material will be effective. While thedevice 10 is rigid, it is important that compressing thedevice 10 in the vertical direction (from top to bottom) be made especially difficult as it is essentially the vertical spacing betweencontainers 24 that is being limited by thedevice 10 and method of the invention. To that end, a lattice ofsupport members device 10.Horizontal support members 26 extend laterally from side to side of thedevice 10 while regularly spacedvertical members 28 extend from the upper 20 to the lower 22 abutment surfaces. Theabutment surface 20 engages the lower 23 surface of theannular flange 27 positioned about the opening of mostcylindrical containers 24. Thedevice 10 is placed in this position to allow thecontainer 24 to be nested into position within alower container 24, but prevents full insertion of onecontainer 24 into another.Lower abutment surface 22 engages theupper edge 29 of thelower container 24 and serves to prevent the full insertion of the upper 24 container into the adjacentlower container 24, thereby avoiding vacuum lock or air lock. Thedevice 10 will still be effective even if thecontainer 24 has noflange 27 as thelower abutment surface 22 will come into contact with thetop edge 29 of thelower container 24 in a stack ofnested containers 24 as will be explained in more detail later. Both the horizontal 26 and vertical 28 members extend from thefront 30 to the rear face 32 of thedevice 10. Thevertical members 28 help prevent compression of thedevice 10 from top to bottom, and this action is greatly aided byhorizontal support members 26 as the two form a lattice which strengthens thedevice 10 against compression in either direction. The use of the lattice structure allows thedevice 10 to be nearly as strong as a solid block of material but with greatly reduced cost and weight. A centrally positionedindicia panel 34 is formed in thefront face 30 of the device, the panel providing space for positioning a product logo or instructional information about thedevice 10, theindicia panel 34 useful as a push tab when applying thedevice 10 to a container. Arecess 38 is formed in the rear face of thedevice 10, which recess terminates atpanel 34, therecess 38 includingsidewall 40.Sidewall 40,support members panel 34 are all of the same thickness so that during manufacture the cooling or curing time for all portions of thedevice 10 are the same, thereby reducing manufacturing cost and time. - The
device 10 as shown is designed to be used “aftermarket” with anycontainers 24 the user may have provided. Thedevice 10 may also be reused and positioned on anothercontainer 24. Again,nestable containers 24 with flat sides can be accommodated by making thedevice 10 flat. Whilelarger containers 24 will of course typically have a larger radius of curvature than smaller containers thedevice 10 may be designed with a curvature corresponding to a large sized (5 gallon) bucket which would allow it to be effective with containers in the 1 to 5 gallon range, depending of course upon the height of the cylindrical vessel (as height affects curvature for any given volume). This is so because thedevice 10 is supplied with adhesive material 50 positioned on the rear face 32 of thedevice 10 so that adevice 10 not matching the curvature of the intendedcontainer 24 will stay in position even though not perfectly flush mounted by way of adhesive 50. The adhesive 50 may be of the peel and stick type. Alternatively, thedevice 10 could use a suction cup arrangement or other mechanical means to ensure thedevice 10 remains in position, which would increase the complexity and cost of thedevice 10 but allow for it to be reused indefinitely. Using adhesive 50 allows for thedevice 10 to be reused once or twice, which is sufficient since thedevice 10 would be used for the life of thecontainer 24. Of course, additional adhesive could be applied by the user in the event that thedevice 10 is reused, the key point being that the type of adhesive initially used is not intended to permanently fix thedevice 10 in position. If the radius of curvature of thedevice 10 is too small (i.e., the container to which it is applied has a large radius of curvature), only the laterally displaced side edges 52 of thedevice 10 will be in contact with thecontainer 24 and thus the user will be instantly aware that thedevice 10 will not be effective for that size and shape ofcontainer 24. In accordance with a preferred use of thedevice 10, at least about 20% of the rear face 32 and its adhesive 50 needs to be in contact with thecontainer 24 in order for the device to be effective. Thedevices 10 may also be made to exactly match the curvature of standardsized containers 24, or sold in packs having a range of curvatures. As previously mentioned, thedevice 10 may be made flat so that nestable containers having flat sides (i.e., having a rectangular profile as in, for example, certain wastebaskets). In this case the radius of curvature of thedevice 10 would be zero. - In use, the
device 10 is positioned on the top edge of anestable container 24 in the position as shown inFIG. 5 . If thecontainer 24 has aflange 27 thedevice 10 is positioned just under theflange 27. Otherwise, thedevice 10 is positioned at the top edge of thecontainer 24 with care being taken to ensure that theupper abutment surface 20 is at least slightly below the top edge of thecontainer 24. Adhesive 50 or other means for fixing the position of thedevice 10 are used to insure that thedevice 10 remains in the effective position as shown. Preferably a peel and stick type adhesive is used, this type of adhesive allowing for re-use of thedevice 10 as discussed above. Thecontainer 24 may then be nested inside thebase container 24 and the process repeated for anysubsequent containers 24 to be nested. - An alternative embodiment is shown in
FIGS. 6A and 6B , and generally indicated by thenumber 100. This embodiment is configured to conform to the shape of virtually anycontainer 24. To that end, a modifiedliving hinge 110 is provided approximately centrally of thedevice 100. Thehinge 110 allows thedevice 100 to be bent inwardly as shown witharrows 104 to effectively reduce the functional radius of curvature of thedevice 100. As in the prior embodiment, thedevice 100 comes with a predetermined radius of curvature, which radius of curvature corresponds to the radius of curvature of a standard 5 gallon bucket. Thehinge 110 is formed so as to have a minimum gap space of about 1/16th of an inch. This allows for thehalves device 100 to bend slightly backwards to accommodate containers with a larger radius of curvature than the device. Thedevice 100 cannot be laid exactly flat because of the curvature ofhalves underside 118 of the device to come into contact with the surface of even a very large diameter (e.g., a standard 55 gallon drum) cylindrical container, this contact being accomplished by depressing thecenter 130 of thedevice 100 when applying it to acontainer 24, thecenter 130 having a push tab as in theprior embodiment 10. Depressing thecenter 130 creates amiddle portion 124 of the underside of the device which can contact the sidewall ofcontainer 24. It can be appreciated that larger containers will have “flatter” sides, i.e., a large radius of curvature, larger than the radius of curvature of thedevice 100. At a minimum, the opposingedges middle portion 124 of thedevice 100 must be in contact with the surface of thecontainer 24 for proper functioning of thedevice 100. Themiddle portion 124 should be at least about 20% of the surface (underside 118) in order to be stably positioned, with the user being able to manually test for steadfastness. Thedevice 100 can be modified to function on a flat sided container by widening the gap of thehinge 110 as shown bybroken lines 118, allowing the twohalves middle portion 124. Depressing thecenter 130 of thedevice 100 after positioning on the side of a container would allow enough of theadhesive material 132 on the underside 118 (124) of the device to come into contact with thecontainer 24 for thedevice 100 to be functional.Indicia panel 134 can be conveniently used as a push tab for depressing thecenter 130 of thedevice 100. It should be noted that in this embodiment that theindicia panel 134 is split due to the formation of thehinge 110, but is still effective as in the prior embodiment. Preferably, as in the prior embodiment, a peel and sticktype adhesive 132 is used to position thedevice 100 on the sidewall of the container. The operation of thedevice 100 is the same as the operation of thedevice 10, except that thehinge 110 allows the curvature of thedevice 100 to be adjusted (increased or decreased) as described above when applying it to a surface.
