INTERLOCKING CONTAINER FOR CONDUCTION OF FLOWABLE MATERIALS
An apparatus for containing and conducting flowable materials, including liquids, pourable solids, or gases, the apparatus having mateable dovetails on four sides, and mateable screw engagements at the top and bottom. The screw engagements are operative to maintain a sealed connection between successive containers, and contain barriers which are adapted to be removed, whereby the material may flow from one interconnected container to the next, in the manner of piping. A lateral connection may additionally be formed by mating portions at the leading and trailing ends of vertically connected containers.
The present invention relates to a container for flowable materials, mateably engageable laterally and vertically with like containers, Connections are provided whereby successive containers may be joined in a sealed manner to conduct flowable materials from one container to the next.
BACKGROUND OF THE INVENTIONThe disadvantages of landfilling solid consumable waste, and plastic containers in particular, are well known. A common alternative is to recycle containers, by collecting, sorting and reprocessing the material, as by grinding, melting, and molding. There are numerous problems with recycling plastics, however. These include the need to carefully sort different types of plastic, the cost of transporting the material to a reprocessing site, the high energy required for melting and reprocessing the material, and the difficulties associated with separating biodegradeable plastics, or plastics containing dyes or additives.
These problems are avoided when a container is reused. A challenge remains, however, to find sufficient demand for containers in their existing form, so that large numbers of them may be reused. Various approaches have been proposed, including forming toy building blocks in U.S. Pat. Nos. 7,175,498 to Garpow et al, and D349046 to Brown, barrier walls in U.S. Patent Publication 2006-0261063 A1 to Grosso, displays and Furniture in U.S. Pat. No. 5,154,295 to Stoner, and sheds in U.S. Pat. No. 4,624,383 to Moore.
In Garpow and Brown, the utility of the containers are limited in that the containers may be joined by mating portions, but are easily separated. In Grosso and Moore, the lateral sides of the container contain portions which mate and interlock, thus enabling a wider variety of structures to be formed. In Grosso, however, there is no integral interlocking vertical connection. In Stoner, cans are threaded together vertically, but are not formed with lateral interconnections. In U.S. Pat. No. 6,276,549 to Fasci et al, vertical and lateral connections are made by snap fastening, but are thus relatively easily pulled apart, as compared to the interlocking connections of Grosso, Moore, or Stoner. In Moore, a vertical threaded connection is disclosed, as well as lateral interconnections on two sides of a container.
While the containers disclosed in the cited references present some potential for reuse, there remains considerable demand for a more versatile, and thus more sought after container, as evidenced by the relatively small percentage of containers that are reused today. It is accordingly an object of the invention to provide a container with high vertical and lateral connection strength, and which affords additional uses, whereby a much greater incidence of reuse is realized.
SUMMARY OF THE INVENTIONIn accordance with the invention, a container is provided for containing flowable materials, such as liquids, pourable solids, and gases. It is a goal of the invention to provide a container which is favored by consumers, whereby consumable producers are motivated to switch from non-reusable containers to containers in accordance with the invention, whereby the environmental benefits of reuse may be realized.
Accordingly, the container may be of any useable size, but embodiments sized in the range of popular consumer containers are advantageous. The container may be formed from a wide variety of materials, including paper, wood, pressed pulp, plastic, metal, or plasticised or plastic coated material. Plastic is a preferred material for drink containers, and thus the container of the present invention is advantageously made with plastic, both for its acceptability from a consumer standpoint, and for its physical properties with respect to manufacturing.
The body of the container may have any of a variety of shapes with an internal volume. Advantageous shapes include those most commonly found for containers of consumer products, including elongated cylindrical or rectangular configurations. The latter has the additional advantage of imparting addition strength to an assemblage of containers.
In accordance with an embodiment of the invention, at least two lateral mating and interlocking portions extend along the side of a container. Interlocking designs include dovetails, or any other shaped profile which engages in a like manner. Specifically, in accordance with the invention, an elongated engaging portion of one container slideably engages an elongated engaging portion of another container along the vertical axis of the container. Containers thus joined cannot be separated by applying a force perpendicular to the vertical axis without deformation or damage to the engaging portions. To facilitate repetitive interlocking on all four sides with a single container design, it is advantageous to have opposing sides that are either both male engaging, or both female engaging.
In accordance with a further aspect of the invention, a spout is formed at a leading end of the container, terminating with a threaded engaging ring. A threaded cap may be applied to the engaging ring to seal the container. An inversion, or aperture is formed at the trailing end of the container, extending into the interior of the container, sized sufficiently large to rotatably receive a spout from the leading end of a second mating container. A threaded receiving ring is disposed at the terminal end of the inwardly extending aperture, operative to threadably engage the engaging ring at the leading end of the second container. In this manner, like containers may be attached end to end, or vertically, one to the other, in a secure manner. The shape of the spout may be any of a variety of shapes, including conical, semispherical, and tubular, or the spout may be eliminated, whereby the engaging ring is disposed proximate the leading end of the container, and the receiving ring is disposed proximate the trailing end of the container.
Structures are formed by connecting successive containers together, vertically and or laterally, in order to achieve the desired configuration. Additional strength and thickness may be generated by combining multiple lateral layers.
In accordance with another aspect of the invention, an additional or alternative connection is formed on the lateral leading and terminating portions of the container. A portion of a coupling is formed partly within the trailing end of the first container, and a portion is formed partly within the leading end of a second container. When containers are positioned end to end, a structure results that is sized and shaped to receive a cap. When a cap is positioned over the two portions, successive containers are secured to each other, vertically, and are also prevented from rotating with respect to each other.
Further in accordance with the invention, an end wall may be provided at the terminal end of the inwardly extending aperture at the trailing end of the container. The wall is operative to retain flowable materials within the container. The wall may be provided with a weakened portion, whereby the wall may be easily pierced, split, pushed aside or removed, as by pushing with a finger, rod, or other object. In so doing, containers connected vertically as described above may be coupled to a supply of flowable material, using threaded connectors or adapters, and the connected containers thus used in the manner of piping to convey the flowable materials from a source to a destination. Further, end wall portions of the lateral couplings described above may also be provided with weakened portions, whereby the flowable material may be tapped at various points along the pipe.
A more complete understanding of the present invention, and the attendant advantages and features thereof, will be more readily understood by reference to the following detailed description when considered in conjunction with the accompanying drawings wherein:
Referring now to the figures in which like reference numerals refer to like elements, an exemplary container 10 in accordance with the invention is illustrated in
Accordingly, the container may be of any useable size, but embodiments sized in the range of popular consumer containers would be advantageous. T he container may be formed from a wide variety of materials, including paper, wood, pressed pulp, plastic, metal, or plasticised or plastic coated material. Plastic is a preferred material for drink containers, and thus the container of the present invention is advantageously made with plastic, both for its acceptability from a consumer standpoint, and for its physical properties with respect to manufacturing.
The body of the container may have any of a variety of shapes with an internal volume. Advantageous shapes include those most commonly found for containers of consumer products, including elongated cylindrical or rectangular configurations. The latter has the additional advantage of imparting addition strength to an assemblage of containers. A container in accordance with the invention may be advantageously formed in a triangular shape, as well as in shapes having more than four sides.
In accordance with an embodiment of the invention, and with further reference to
For male engaging portions, a connecting member extends outwardly from the side of the container, and conversely, for female engaging portions, a connecting member extends into the interior of the container. In each case, the extension has a narrow region close to the container side, and a wider portion further away from the container side.
Containers thus joined cannot be separated by applying a force perpendicular to the vertical axis without deformation or damage to the engaging portions. To facilitate repetitive interlocking on all four sides with a single container design, it is advantageous to have two sides that are male engaging, such as portions 14,14a, and two sides that are female engaging, such as portions 16,16a. In the figures, opposite sides of the container have like engaging portions, It is additionally possible to enable continuous lateral connections where two adjacent sides have male engaging portions, and the remaining two adjacent sides have female engaging portions. Where more limited lateral connections are acceptable, an engaging portion may be formed on one side of the container, however a male style and a female style container would be required. For containers with two engaging portions, it is advantageous to have one engaging portion be male, and the other female, in order that a single container style will suffice for lateral connections.
In the figures, interlocking portions 14,16 extend from a leading end 100 of container 10 to trailing end 102. It should be understood, however, that interlocking portions 14,16 may extend transversely, and thus perpendicular to an axis passing through the leading and trailing ends of the container, without departing from the spirit and scope of the invention.
In accordance with a further aspect of the invention, a spout 24 is formed at leading end 100, terminating with a threaded engaging ring 26. A threaded cap 28 may be applied to the engaging ring to seal the container. An aperture 30 is formed at trailing end 102, extending as an inwardly projecting inversion into the interior of the container, sized sufficiently large to rotatably receive a spout from the leading end of a second mating container. A threaded receiving ring 32 is disposed at the terminal end of the inwardly extending aperture, operative to threadably engage the engaging ring 26 at the leading end of a second container. It should be understood, however, that threaded engagement may be provided at any point along spout 24, with correspondingly positioned threads within aperture 30.
In this manner, like containers may be attached end to end, or vertically, one to the other, in a secure manner, as shown in

The threaded connection between engaging ring 26 and receiving ring 32 advantageously forms a gas or liquid tight seal between successive containers. In one embodiment, the seal is formed along the periphery of end wall 56, although a seal may alternatively be formed below end wall 56, closer to or at trailing end 102.
Accordingly, containers connected vertically as described above may be coupled to a supply of flowable material, using threaded connectors or adapters, and the connected containers thus used in the manner of piping to convey the flowable materials from a source to a destination. Lateral couplings, as described above, may have weakened areas 48,50 removed, whereby the flowable material may be tapped at various points along the pipe.

Connected as described above, containers in accordance with the present invention may be used to form a variety of structures, including as examples landscape or irrigation piping, solar heating structures, fluid or gas reservoirs, and potable or sanitation water conduits. Containers may be cut transversely to form a cup or receptacle, whose surface area may be increased through lateral connections. A combination of lateral and vertical connections, in combination with transverse cuts as described, can be used to collect liquids or gases and conduct them to a collection point, for example to collect rainwater, or to concentrate gas production from decomposing farm waste. It should be emphasized that the present invention is not limited to the uses described above, but may be adapted to a variety of uses not described herein.
Due to the very low cost of containers in accordance with the invention., it is possible to construct structures which would otherwise be unfeasible in many communities, and thus may significantly improve a standard of living therein, thereby reducing human suffering. Containers may be collected in communities where they were initially used to contain a consumer product, and thereafter transported in bulk to communities where they may be used as described herein.
