'I'his invention relates'generally to improvements in the art of packaging commodities, and relates more specifically to an improved decorative and protective wrapper for concealing or confining one or more articles, and to an improved piackage resulting from the use of such a wrap- D ng.
Generally stated, an object of the invention is to provide a simple and highly protective wrapper for diverse articles, which will produce an attractive and compact final package.
It has heretofore been customary to wrap articles such as chocolate coated confections, in double flexible wrappers, each comprising an inner metal foil Wrapper and'an independent outer transparent or translucent wrapping of the same size, surrounding and cooperating with the inner foil wrapper to protect the article and to produce an attractive external appearance. By utilizing a tin or aluminum foil inner wrapper and an outer orange colored translucent wrapping for the inner wrapper, a glowing golden color results; and with the aid of suitably colored printing or other decorations applied to the outer wrapping, it is possible to produce a relatively attractive final package. Because of the relatively high cost of metal foil, and of the fact that the outer and inner components of these prior wrappers were ofthe same area or size, these previous composite wrappings were rather costly to produce, and considerable metal foil was wasted since itwas used to also cover relatively guarded rear portions of the articles such as may be sufficiently protected merely with the aid of the cheaper outer wrapping material.
It is therefore a more specific object of the present invention to provide a less'expensive but equally protective wrapper which possesses all of the above stated advantageous characteristics of the prior composite wrappers referred to.
Another specific object of the invention is to provide an improved wrapper for articles such as chocolate` bars or chocolate coated confections, which will effectively protect only certain relatively exposed portions such as the top, sides, and ends of the articles against detrimental action of light, but which will totally conceal and protect the commodity against moisture.
Still another specific object of the invention is to provide a durable and compact composite wrapping which can be readily manufactured and utilized with minimum waste of material and hence at minimum cost, and which constitutes a unitary covering adapted to be applied to an article in one operation.
. A further specific object ofthe invention isv to provide an improved package of highly attractive and ornamental appearance, wherein the concealed article is most effectively protected against possible deterioration dueto light, moisture, or other exposure.
These and other objects of the invention will be apparent from the following detailed description.
A clear conception of an embodiment of the invention, and of the mode of producing'and of utilizing improved wrappers manufactured in accordance therewith, may be had by referring to the drawing accompanying and forming a part of this specification, wherein like reference characters designate the same parts in the several' views.
Fig. 1 ls a rear plan view of one of the improved composite wrappers showing portions thereof folded up so as to show the details of construction, and also showing fragments of adjoining wrappers in dot-and-.dash lines;
Fig. 2 is a transverse section thruvthe wrappers of Fig. 1, taken along the line ZEE-II; and
Fig. 3 is a side elevation of a package utilizing the improved wrapper.
While the invention has been shown and described herein as being specically 'applied to a wrapper which is especially adapted for use in the packaging of chocolate bars or the like, it is not intended to limit the scope by such specific disclosure.
Referring to the drawing, the improved composite wrapper comprises in general an outer sheet 5 of transparent or translucent'material; an inner or intermediate strip or sheet 6 of metallic foil adhesively secured along one of its edges to the inner surface of the sheet 5 as indicated by the area l; and preferably an innermost backing sheet 8 attached directly to the rear surface of the inner sheet- 6.
The outer sheet 5 may be formed from a continuous ribbon of material such as glassine paper, which, in the embodiment speci'cally illustrated, is orange colored and semi-transparent thruout its entire area. This material is moisture resistant and will not stick toarticles such as candy bars because of its smooth and non-porous. texture. The outer surface of the sheet 5 may, if desired, be provided with a decorative border 9 and identifying printing, to form a local window l0 as shown, thru which a portion of the `underlying metal foil strip 6 is hazily, but not clearly, visible.
The metallic foil inner strip or sheet 6 is of considerably less width than, but of the same length as'the outer sheet 5, the area of this sheet 5 being suicient to cover only the entire top,
portions of the sides, and' the entire ends of the articles which are to be concealed in the wrapper,
as shown in Fig. 3. Such metallic foil will tear rather readily and if brought into direct contact with articles such as candy or chocolate bars, will vtend to stick to the article. 'I'he backing sheet 8 is therefore provided as a reenforcement for the foil and to prevent sticking. As specically shown, the sheet 8 may be formed oi tough tissue paper `and is attached directly to the rear surface of the foil sheet 8 by applying a paraiiin coating or other adhesive between these elements.
`In some instances, the sheet 8 may consist of a strip of box-cover paper, comprising a tough tissue paper coated with foil. These strips may, in any event, be formed Vas continuous ribbons which, as previously indicated, are adhesively secured to the outer sheet ribbons at lineal areas 'l before the composite ribbons are severed into lengths to form the unitary wrappers. While the inner strip 6 an'd'sheet 8 have been shown in Fig. 2 as extending away from the outer sheet 5 at a slight angle, the outer and inner components of. the wrapper will normally be iiat against each other. .y
During the manufacturaof the improved wrappers, the composite inner strip, comprising the foil sheet 6 andthe backing sheet 8, is hrst produced by attaching these componentsy to each other with the aid of paraiiin; and this parain, besides' connecting these parts, also serves to make the inner strip moisture resistant and prevents the foil from coming in direct contact with the article. The 'inner foil strip 6 is then adhesively attached -along one edge and' at the area l to the inner surface of the ribbon from which the outer sheets 5 are to be formed, thus producing a continuous ribbon of the outer wrapping material having a strip of the inner wrapping material secured to the inner surface thereof and lying hat against this surface. The composite ribbon is subsequently severed into suitable lengths to produce the final wrapper umts in succession, and the outer surfaces of these wrappers may be provided with decorative printing, such as the borders 8,- either before or after the severing operation.
Each of individual articles may subsequently be concealed within one of the composite wrappers thus produced in one operation by locating the wrapper so that the protective inner strip directly engages the top, portions of the opposite sides, and the ends-"of the article, and by sub- 'or glowing golden effect. The gold color results fron the use of a semi-transparent orange colored I outer sheet 5, cooperating with a silver colored shiny surfaced intermediate sheet 6. 'I'he at tachment of -the foil sheet 8 to the inner surface of theouter sheet 5 along an edge portion only 'a layer of adhesive-between these sheets thru-out their entire cooperating areas. 'I'he concealed article is eectively protected against detrimental action bylight and moisture at those portions thereof which are exposed during normal display of the package, and the entire article is furthermore protected against moisture and contact lwith other objects, at the bottom, by the multiple layers of the outer sheet 5 alone. While the wrapper shown has been provided with a definite window 10, 'such window may obviously be omitted and any other form of decoration may beapplied to the outer surface of the hesion to the wrapped articles. The nal package Y presents a neat and highly attractive appearance, and by limiting the area of the foil, the cost of producing the improved Wrapper is reduced to a minimum without destroying the effectiveness thereof. The outer wrapper mayfobviusly be formed of material other than glassine paper, and other foils may be utilized in producing the sheet t; but in any case, it is desirable to have the outer sheet formed either of transparent or semitransparen't sheet material which is` moisture proof and relatively tough. The uniform coloring of the outer transparent sheet 5, which may be produced in any suitable manner, may extend thru-out the entire area of this sheet or only over the intermediate sheet 6, and either the coloring of the outer sheet or the coloring of the foil sheet may be varied to produce a great variety of attractive emblazoned eiects; and the reading or decorative matter may be applied to the surface of the outer sheet 5 above the foil refiector, by printing or otherwise. The improved Wrapper has proven highly successful in actualuse and may b e conveniently handled and applied to produce a package having minimum bulk.
It should be understood that it is not desired to limit the invention to the exact details of construction and to the precise mode of utilizing the Wrappers herein shown and described, for various modifications within the scope oi' the claims may occur to persons skilled in the art.
It is claimed and desired to secure by Letters Patent:
