CONTAINERS WITH REDUCED MATERIAL CONTENT
A plastic injection molded container is provided with reduced material content. The plastic container may be a dental floss container but may be any type of container for storing any type of product. The plastic container is comprised of an open framework comprising at least one opening and at least one solid portion and defining an open container body, a flexible sheet overlying said at least one opening, and a bond bonding said flexible sheet exclusively to said at least one solid portion. In an embodiment, the flexible sheet is a label and the bond is an adhesive. The label may be provided with a clear opening for viewing the contents of the container.
This is a non-provisional application of provisional application serial No. 61/246,692, filed on Sep. 29, 2009, which is hereby incorporated by reference and the priority benefit of which is hereby claimed.
FIELD OF THE INVENTIONThe invention relates to packaging, and more particularly, to containers with reduced material content.
BACKGROUND OF THE INVENTIONA need exists for a package or container such as a plastic container which uses less plastic material. By using less plastic material, a lower cost package will result, less plastic will be processed and less plastic will be disposed of, for example, in garbage dumps and landfills. In this manner, by reducing the amount of plastic in a potentially disposable container, economical and environmental improvements may be achieved.
SUMMARY OF THE INVENTIONIn one embodiment, a plastic injection molded open-walled cage or open plastic framework is formed to provide structural support to a closed-wall package. The cage or framework is then covered or wrapped with a thin sheet or label to cover the openings in the cage or framework. The label can either be clear, opaque or a combination of clear and opaque. For example, a label can be provided with a clear plastic window to allow a user to view within the container to see the level of product remaining inside of the container or package.
The label which covers the opening in the cage or framework is provided with an adhesive in predetermined areas which corresponds only to those areas which will contact the cage or framework. In this manner, no adhesive will be exposed to any product within the cage or framework. Stated another way, only those portions of the label which do not include adhesive will be exposed to the product within the framework. The label can be formed of any conventional sheet material such as paper, plastic, fabric, etc.
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:
One application in accordance with the present disclosure is the provision of a plastic injection molded container and label assembly for use as a dental floss container. However, the general construction and concept of this disclosure may be applied to virtually any type of package constructed from any type of material for any type of article.
Referring now to
As seen in
A top reinforcing bar 22 extends between the side walls 12 and interconnects with the central support or stabilizing bar 20. A similar construction is provided on the back wall of the container 10.
The hinged top 16 can include a lip 17 having a detent 17a that engages a notch (not shown) on the top reinforcing bar 22. The detent 17a on the lip 17 secures the hinged top 16 in a closed position to secure the contents of the contents of the container 10 therein.
The container 10 of
A generally rectangular flexible label is bonded to the container 10 to cover all of the openings 18 (other than the top opening which is covered by lid 16). Only selective areas of the label are bonded to the container 10, for example along side walls 12 and/or supports 20, 22.
Another example of the disclosure is shown as the dental floss container 10 in the embodiment of
The openings 18 in the front and back of the container 10 are covered by label portions 36 and the side windows 26 are covered by label portions 38. When the label 30 of
