Expandable container
Traditional structured-containers have a maximum holding capacity upon exceeding of which would allow excess articles fall out of the structured-container by way of gravitational pull. The utility of these structured-containers is thus limited. The present invention discloses an expandable container where a net container is coupled to a traditional structured-container to thus synergistically and substantially increase the maximum holding capacity of the traditional structured-container.

The present invention is related to a container for transporting articles. More specifically, the present invention is related to an expandable container that can be used to transport articles.
Containers in general are greatly appreciated for their ability to house articles and making transportation of articles manageable. On a daily basis, people use containers in one form or another. The utility value of a container is greatly increased if its holding capacity is expandable so that it is both convenient to use for transporting a small number of articles as well as a large number of articles. Toward the goal of increasing the utility value of containers, there are a number of inventions disclosing how to add to the holding capacity of a container.
U.S. Pat. No. 5086917 issued to Dziersk discloses a utility caddy for use with or without a bucket. As shown in
U.S. Design Patent No. D410329 issued to Wyatt discloses a combined rucksack and net bag. This container overcomes the shortcoming of Dziersk in that the expanded portion is a net that is collapsible when not needed and expandable when needed. Therefore, the net only occupies minimum amount of storage space when not in used. However, a shortcoming of this container is that while the net is useful to carry items much smaller than the main container, its juxtaposition relative to the rucksack while discretely increase the overall holding capacity of the rucksack, it is unable to either integrally or synergistically increase the holding capacity of the rucksack. For example, if an article is so large that it is unable to be fitted into the rucksack, the net is incapable to increase the overall capacity of the rucksack to hold this article.
U.S. Design Patent No. D429886 issued to Avent discloses a foldable carrying case with a separable net bag. Avent shares the same shortcoming as Wyatt in that the net bag and the three separate folders can only discretely increase the holding capacity of the net bag, but they cannot either integrally or synergistically increase the holding capacity of the net bag so as to enable one single large article to be fitted into the net bag and the folders.
U.S. Design Patent No. D421178 issued to Dandini discloses a carryall-beach blanket combination.
U.S. Pat. No. 5944213 issued to Alicea discloses a deformable retaining net. In this invention, a deformable retaining net 10 is added to a container 22. However, the deformable retaining net 10 is not able to increase the holding capacity of the container 22. It merely helps to retain any articles already housed in the container 22 so as not to fall out of the container 22. In essence, the deformable retaining net 10 has not increase the holding capacity of the container 22.
SUMMARY OF THE INVENTIONTo overcome the above-mentioned shortcomings of the prior art inventions, the present invention discloses a net-container when used in conjunction with a structured-container can increase the overall holding capacity as an expandable container so as to hold either a single large article or a large pile of articles that the structure-container by itself cannot hold.
It is apparent that by combining the structured-container with the net-container would synergistically increase the holding capacity of the structured-container and the net-container when they are both being used separately.
BRIEF DESCRIPTION OF THE DRAWING
Figure 11 shows a rectangular opening structured-container that the net-container may be coupled thereon to form an expandable container of the present invention.
As clearly shown in
It is visually apparent that the perimeter of the rim-portion 502 is larger than the perimeter of restrainer 104 after it has been tightened. Therefore, the net-container 100 and the structured-container 302 are securely affixed to each other. By so affixing the net-container 100 onto the structured-container 302, the overall holding capacity of the resulting expandable container 300 is substantially and synergistically increased to house either a single large article or a single pile of articles which the structured-container 302 alone cannot fully house.
To visually illustrate the difference in holding capacity of the structured-container 302 and the expandable container 300 of the present invention,
On both ends of the net material are overlapping regions O. Since there are many devoids in any net material, overlapping regions O are needed to provide sufficient amount of material for affixation. The overlapping regions O is created by folding overlap portions 0 from both ends along fold-lines FL and FR. This folding of the overlapping regions O would make the folded ends to have double the amount of materials than what otherwise is only a single layer of net material. Both folded ends totaling four layers are then brought together in an overlapping fashion and are affixed together. The end result is that the net material is formed into a cylindrical shape if both end openings are fully open.
As
As an example of the dimensions of the present invention, the perimeter of the round edge of the structured container is 54 inches. The widest opening of the net-container is 55 inches. The height of the structured-container is 12 inches, and the height of the net container is 22 inches.
When a user needs to maintain either the top or bottom restrainers 102 or 104 to a desired loop size, fasteners devices 402 are used. A diagram view of a fastener 402 is shown in
Since the net-container 100 is highly adaptable to different shapes, it can be used for structured-containers with different opening shapes. Besides a round-opening of the structured container 302, the net-container 100 can also be used, for example, on a rectangular-opening structured-container as shown in
From the foregoing detailed description, it will be evident that there are a number of changes, adaptations and modifications of the present invention that come within the province of those persons having ordinary skill in the art to which the aforementioned invention pertains. However, it is intended that all such variations not departing from the spirit of the invention be considered as within the scope thereof as limited solely by the appended claims.
