Definitions
- the present invention is directed generally to a tapered container and, specifically, to a tapered container capable of being nested or collapsed during shipment or storage.
- Containers are ubiquitous across various industries, for example food or dairy products such as ice cream, with a variety of styles, shapes, and volumes being used depending on the needs of a particular industry or entity.

- One problem with this method of providing containers is the fact that each container occupies a given space, such that during shipment of containers one is actually shipping a relatively small amount of material (the container itself), and a large volume of air (the empty space inside of the container). This leads to excessive shipping costs associated with the transport of such containers.
- a second solution to the problem is for a company or other entity to produce the desired container on-site rather than have containers delivered to them from a supplier.

- Not Applicable.
- The present invention is directed generally to a tapered container and, specifically, to a tapered container capable of being nested or collapsed during shipment or storage.
- Containers are ubiquitous across various industries, for example food or dairy products such as ice cream, with a variety of styles, shapes, and volumes being used depending on the needs of a particular industry or entity. Often, containers are made or formed at one location and then shipped to another location where they are filled with the desired product. One problem with this method of providing containers is the fact that each container occupies a given space, such that during shipment of containers one is actually shipping a relatively small amount of material (the container itself), and a large volume of air (the empty space inside of the container). This leads to excessive shipping costs associated with the transport of such containers.
- One solution to this problem has been to construct containers with tapered sidewalls such that the containers “nest” during shipment. Thus, a greater number of containers can be shipped in the same amount of space as that occupied by non-nesting containers. There are, however, problems with this approach. Nested containers are more difficult to produce that non-nested containers, and engineering considerations such as maintaining a uniform sidewall must be taken into consideration.
- A second solution to the problem is for a company or other entity to produce the desired container on-site rather than have containers delivered to them from a supplier. This solution, however, requires expensive machinery to be located on-site for container construction and is not a viable option for small business or businesses with limited space.
- In addition to the above, typical prior art containers such as, for example, three-gallon ice cream containers, include metal ring portions along a top opening thereof. These metal rings may have sharp edges that may be exposed during assembly of the container, representing a potential hazard to the person doing the assembling or handling the container while in use. Further, the presence of the metal ring can interfere with modern x-ray inspection techniques that may be applied to food products in a given industry. Elimination of the ring entirely is not an option, however, as the ring provides required support and stability to transport relatively heavy items, such as ice cream, in the container.
- The present invention provides a nested container that is also collapsible, allowing efficient shipment of the container and easy use of the container by a user thereof. The present invention further provides a container having a non-metal ring portion to reinforce the container.
- The present invention provides a nestable container that includes a sidewall having a substantially cylindrical shape, a ring portion adapted to engage the upper opening of the sidewall, and a bottom portion adapted to engage a bottom opening of the sidewall. The diameter of the upper opening of the sidewall is greater than the diameter of the lower opening of the sidewall such that the sidewall of the container is tapered. Also provided is a lid adapted to removably engage the ring portion.
- It is preferred that the outer surface of the sidewall have a polymer coating, such as, for example, a polyethylene coating, and that a surface of the bottom portion have the same coating. Thus, the bottom portion can be heat sealed to the sidewall portion.
- It is also preferred that the sidewall portion have corrugations allowing the tapered sidewall to be more easily formed and allowing for flat shipment of the present container.
- In another preferred embodiment of the present invention, the sidewall portion includes a chemical release coating along an inner surface thereof.

It is preferred that thering portion 26 of the present container is substantially the same as thering structure 16 used in prior art containers such as that shown inFIG. 1 , but formed from plastic or similar non-metallic material. This allows for minimum retooling of a manufacturing facility in the move from prior art containers to the present invention, and also maintains certain dimensions of the container that may be important in the industry in terms of shipping, storing, marketing, use, and the like.Ring 26 includes an annular ring adapted to receive the upper edge ofsidewall 22, thereby providing support forcontainer 20. -
Sidewall 22 of the present container is preferably constructed from cardboard, though any suitable material may be used. Scoring 28 insidewall 22 allowscontainer 20 to be easily assembled and also allows forcontainer 20 to be collapsed during shipping or storage. Scoring 28 also preventnested containers 20 from sticking together when two ormore containers 20 are properly nested. It is contemplated that at least twoscorings 28 are present insidewall 22, each being substantially opposite the other. More than twoscorings 28 may also be used. The height ofsidewall 22, as well as the diameter thereof when assembled, may be varied according to the needs that the final container must meet. The angle at which the sidewall tapers (referred to herein as the draft angle of the container) may also vary according to the desired properties of the container. In a preferred embodiment of the present container, the draft angle is about 5 degrees. Determination of the dimensions ofcontainer 20 necessary to meet specific needs is described below. -
Sidewall 22 preferably includes a polymer coating along at least a portion of an outer surface thereof, such that bottom portion 24 (described below) may be heat sealed thereto. It is preferred that the polymer coating is composed of polyethylene, though any suitable polymer may be used. Examples of other suitable polymers include, but are not limited to, polyvinyl chloride, ionomer resin, polyamides, polypropylene, polycarbonate, polystyrene, and combinations thereof. It is also preferred thatsidewall 22 include a chemical release agent along an interior surface thereof. -
Bottom portion 24 ofcontainer 20 is best seen inFIG. 4 . If is preferred thatbottom portion 24 be fixedly attached tocontainer 20 by heat sealing, although any suitable method of attachment may be used. For example, during construction ofcontainer 20,bottom portion 24 may be attached to sidewall 22 ofcontainer 20 by application of glue to eitherlip portion 30 ofbottom portion 24, or bothlip portion 30 andannular wall 32 ofbottom portion 24.Annular wall 32 mates with an interior surface ofsidewall 22 and defines a diameter of the lower portion ofsidewall 22. In the embodiments of the present invention whereinbottom portion 24 is heat sealed tosidewall 22, it is preferred that the portion ofbottom portion 24 to be sealed tosidewall 22 is coated with a polymer, preferably polyethylene. Any suitable polymer may be used including, but not limited to, polyvinyl chloride, ionomer resin, polyamides, polypropylene, polycarbonate, polystyrene, and combinations thereof. -
FIG. 3 provides a view of twocontainers 20 shown nested with one another. The two containers are identical as shown in the drawings, each having asidewall 22, aring portion 26, andcorrugations 28. Both containers further include abottom portion 24, thoughbottom portion 24 of the top container is not visible because it is contained within the bottom container. -
FIG. 4 provides an exploded view of a container constructed in accordance with the teachings of the present invention. In the figure,bottom portion 24 is more fully depicted than in the previous figures.Bottom portion 24 preferably has anannular wall 32 and alip portion 30 that extends perpendicular toannular wall 32 and around a circumference ofbottom portion 24.Annular wall 32 andlip portion 30 provide surfaces which may be heat sealed tosidewall 22 ofcontainer 20, or to which glue may be applied to securebottom portion 24 to sidewall 22 when formingcontainer 20. -
FIG. 5 is an elevational view of twostacked containers 20 constructed in accordance with the teachings of the present invention. Shown in the figure are twolid portions 34 adapted to snap into place overrings 26, which can't be seen due to the presence oflid portions 34. Whenlid portions 34 are in place, an airtight seal is created betweenlid portions 34 and rings 26, and the upper surface oflid portion 34 creates a surface upon which asecond container 20 may be stacked. It is preferred thatcontainer 20 is dimensioned such thatlid portion 34 adapted for use withprior art container 10 is also capable of being used withcontainer 20. This allows for an interchangeability of parts between prior art containers and the present container. - A important feature of the present invention is the ability to adapt
container 20 to a variety of volumes while maintaining a constant diameter ofring portion 26. Thus, where a diameter ofring portion 26, and thereforelid portion 34, has become standard in an industry, the present,new container 20 may be used without a need to change ring or lid diameters. This also allows for ease of storage of the present container and ensures that the same number of containers may be placed side by side in storage such as, for example, a refrigerated ice cream display at an ice cream retail outlet. - For a
prior art container 10, the formula for determining volume is: -
V=πr2h - where V is total volume, r is the radius of the container, and h is the height of the container.
- Given the
present container 20, the formula is altered to provide the following equation: -
- where V is total volume, d is the inside diameter of the upper opening of the container, h is the height of the container, and θ is the draft angle of the container sidewall 22 (i.e. the angle between the upper opening of the container and the bottom opening of the container; the angle at which the
sidewall 22 slopes). The equation provided allows a user of thepresent container 20 to easily determine a draft angle or height of the container necessary to achieve a desired volume while maintaining a constant diameter of an upper opening of the container (and ofring portion 16 and lid portion 34). It should be noted, however, that the equation above can be utilized to determine the dimension for nested containers having varying diameter upper openings or rings 16, and such containers are still contemplated to fall within the teachings of the present invention. - The detailed description set forth above is provided to aid those skilled in the art in practicing the present invention. The invention described and claimed herein, however, is not to be limited in scope by the specific embodiments disclosed because these embodiments are intended to be illustrative of several aspects of the invention. Any equivalent embodiments are intended to be within the scope of the present invention. Various modifications of the invention which do not depart from the spirit or scope of the present invention, in addition to those shown and described herein, will become apparent to those skilled in the art from the foregoing description. Such modifications are also intended to fall within the scope of the appended claims.
