' The present invention relates to containers of the type constructed of transparent cellulose sheeting, and has particular reference to improvements in such containers whereby articles may be wrapped or packaged 'with transparent cellulose sheeting in such a manner that the package is more permanent and rigid and easily closed after insertion of articles to be packaged.
A principal object of the invention is to provide a package of the type described which will have a stable body shape or form.
An additional object is the provision of a package having an outer casing of transparent cellulose sheeting which may be easily closed by twisting the ends to'form a container of standard size and shape.
These and other objects will be apparent upon a consideration of the following description of a preferred embodiment of my invention and by reference to the accompanying drawing in which Fig. 1 is a front view of a package or container constructed in accordance with my invention.
Fig. 2 is a fragmentary longitudinal section of the package shown in Fig. 1; l Fig. 3 is a cross sectional view of the package shown in Fig. 1, taken along line 3-3 thereof;
Fig. 4 is a perspective view of a modified embodiment of the invention; and
Fig. 5 is a perspective view of another modification of a package shown in Fig. 1.
It is customary in wrapping various articles, such as candy bars, nuts and the like in a transparent cellulose sheeting, to close the package by sealing or folding the edge portions or by twisting the ends of the package together about the packaged material. In this manner there is formed a package which conforms to the shape of the article contained therein. As the transparent cellulose sheeting is of a somewhat fragile nature, wrappers in packages of this type have a tendency to tear or be broken, largely due to their close contact with the articles packaged. Also the wrappers are of no standard shape, thereby detracting from the beneficial effect of the cellulose sheeting by a lack of uniformity.
In accordance with my invention I have provided a package which is constructed of the usual thin flexible transparent cellulose sheeting such as the product sold under the trade-mark Cellophane and with this transparent flexible wrapper is combined a skeleton structure of substantially the same material but of a heavier and less deformable nature.
As shown in the drawing, the package is formed by .combining a transparent flexible wrapper I0 with an inner and heavier'band of similar material, indicated at l I. This bandof heavier material may be constructedof regenerated cellulose or similar materials. Celluloid has been emplayed for the purpose to considerable advantage. 5 The member I l is of ring-like formation and defines the end structures of the package. Ina preferred embodiment of my invention the ring structures I l 'are adhesively secured to the transparent cellulose wrapper, whereby to prevent rela- 1o tive movement between the ring I I and the wrapper. In this manner a package of permanent and standard form is provided.
A particular advantage of the use of the rings II is that the ends I! of the package may be 15 twisted to form a closure of the wrapper subsequent to the insertion of the articles to be packaged, the rings I l forming the base beyond which the twist does not pass, thereby insuring a neat package of standard configuration. In producgo tion of .the package a web of the transparent cellulose is fabricated with two strips of the heavier sheeting II, and wrappers of the proper length are chopped from the end of the fabricated sheet in the usual manner forming wrappers of 25 this type. Ordinarily the wrapper will be printed with one or more colors before or after 'fabrica tion. The package is formed by overlapping the edges of the wrapper and sealing the same together by suitable glue, as shown in Fig. 3.
In order to .provide the package with longitudinal rigidity, the bands Il may be connected together by means of longitudinally extending strips composed of the same material as the bands I I. The strips l3 may be formed integrally 85 with the bands II, but, as shown in Fig. 4, it is preferred to secure a plurality of the separate strips to the bands H. The strips II are secured to the bands II by means of a suitable adhesiveor by heat or solvents as will be under- (0 stood. The strips l3 are applied during the fabrication of the wrapper and the package is formed in the manner described with respect to the embodiment shown in Fig. 1.
The package shown in Fig. 4 has considerable rigidity but, at the same time, the relatively heavy framework composed of the strips l3 and rings or bands is sufliciently flexible to allow the package to be deformed temporarily. The natural springiness of strips l3 and bands ll cause the package to return to its normal shape when pressure against it is released. a
In Fig. 5 the end-defining rings ll composed of relatively heavy cellulose material are formed as a continuous band. ,These rings are not seloading of the package.
cured to the cellulose sheeting except by friction of the latter about the rings. An advantage of this type of structure is that upon removal of portions of the contents of the package through an untwisted end closure, the ring may be pressed inwardly of the package andthe cellulose sheeting twisted to a greater extent, thereby shortening the package without destroying its general shape or rigidity. With this type of package the wrapper may-be sealed longitudinally about the rings I4 and the package loaded through the untwisted ends of the wrapper, the latter being twisted into closed position subsequent to the It will be noted that by employing transparent material as the skeleton or framework for the package, the package is made considerably more rigid than hasbeenpossible heretofore withoutimpairing its transparency ordisplay characteristics. Unique printing designs may be combined in the package by suitably printing thev skeleton in a distinguishing manner from theremainder of the:wrapper. Also it is often desirable to print the twisted ends of the wrapper in a distinguishing' manner, so that when the ends are twisted to close the package they may form a striking contrast with the body portion thereof.
It will be recognized that changes may be made in the structure described heretofore without departing from the spirit of my invention, and all such changes and modifications are intended to be included in the appended claims.
l. A package-of the type described, comprising opposed continuous bands of relatively heavy cellulose sheeting forming end frame members, and a relatively thin wrapper of transparent cellulose sheeting folded about said bands to form a body enclosure for the package, the ends of said cellulose sheeting extending beyond said bands and being formed into closed condition from said bands.
2. A package of the type described, comprising a frame structure composed of opposed continuous bands of relatively heavy transparent cellulose sheeting forming end frame'members, longitudinally extending strips of relatively heavy cellulose sheeting joiningsaid continuous bands. and a wrapper of transparent cellulose sheeting folded about said frame structure and having its end portionstwisted into closed position about.
the outer edges of said continuous bands.
