Definitions
- the primary objective of this invention is to make available a relatively large(50l50 fluid ounces) expanded polystyrene container which is substantially strengthened by suitable reinforcing means.
- a further objective is to insure that such reinforcement is compatible for inclusion in the basiccontainer construction considering cost, end usage, manufacturing technique, weight and related problems.
- FIG. 1 is a front elevational view of a container illustrating a preferred embodiment of the invention
- FIG. 2 is an enlarged partial cross-section taken along line 2-2 of FIG. 1;
- FIG. 3- is a bottom view of the container shown in FIG. 1;
- FIG. 4 is a front elevational view of another embodi ment of the invention partially broken away.
- a typical expanded polystyrene container incorporating the features of the instant invention is designated by the numeral in FIG. 1.
- Such container in the preferred embodiment is approximately 9 inches in diameter and 10 inches tall.
- the holding cavity thereof is about 170 fluid ounces.
- polystyrene containers of this size under loaded conditions may experience significant stresses, especially when subjected to handling. Therefore, an economical and effective means for reinforcing these containers was a practical necessity if repreated failures in usage were to be avoided.
- container 10 is formed by an integral side wall area 12 and a bottom wall 18.
- the basic configuration of the container is cylindrical, as is obvious from FIG. 3.
- the container shown is for the most part similar to the yarious cup constructions which are commonly used for hot and cold drinks of various types.
- the sidewall area 12 tapers upwardly and outwardly to its upper peripheral edge 14 which is of a bead-like configuration.
- an upper rim area 16 is provided proximate the upper peripheral edge 14.
- the upper peripheral edge 14 and rim 16 of container 10 in accordance with the dictates of this invention are, however, reinforced with a band-type material 20. Such material is afi'ixed to the rim 16 by an adhesive composition 22 immediately under and adjacent edge 14.
- this material is an adhesive-backed pressure-sensitive tape of between 0.250 and 0.500 inches wide.
- Various tapes of this type have been found to be satisfactory in providing the intended reinforcement.
- Several typical such materials are manufactured by the Minnesota Mining and Manufacturing Company and are of polyester film, cellophane, crepe and mylar constructions. Others, of course, may be equally satisfactory and may be selected for reasons of clarity, decorative or other effects.
- the 3M polyester film material is preferred because of its clarity and unobtrusive appearance around the container exterior. Likewise, it is preferred to use a single 0.375 inch tape strip; however, the width thereof may vary between 0.250 and 0.500 inches and it may be, in certain circumstances, advantageous to employ a plurality of strips adjacently positioned on the rim area. Tape material 20 is also overlapped as at 24 to assure that the container or tab is reinforced around its entire peripheral extent. This may also be modified if, for example, a plurality of tape strips are employed. FIG. 4 illustrates such an arrangement of plural tape strips.
- a reinforced plastic package comprising a container member of expanded polystyrene between about a 50 and to 200 ounce capacity and having outwardly tapering sidewall means extending from a bottom wall member to an upper peripheral edge forming the open end thereof, and including at least one tape strip fixedly adhered to the exterior of said upper peripheral edge around and in close contact with therim of the container member so that the upper portion thereof will retain its basic size and shape even under tensile loading conditions.

Abstract
Description
Claims (3)
- 2. A reinforced plastic package according to claim 1 wherein said tape strip encompases substantially the entire peripheral extent of said package.
- 3. A reinforced plastic package according to claim 2 wherein said container walls are of an expanded polystreme composition of approximately about between 0.125 and 0.250 inches thickness and wherein said tape is a pressure-sensitive adhesively backed material adhered to the container and is about between 0.250 and 0.500 inches wide.
- 4. A reinforced plastic paCkage according to claim 1 wherein said tape strip includes a multiplicity of pressure-sensitive tape strips respectively spaced from one another and each encompassing substantially the entire peripheral extent of said package.
