SANDWICH WRAPPER Filed Feb. 4, 1937 2 Sheets-Sheet 2 A i iornqys Patented Jan. 25, 1938 UNITED STATES PATENT OFFICE 4 Claims.

' This invention relates to what is believed to be a new and novel sandwich or lunch wrapper, and the preferred embodiment of the invention pertains to that subdivision in this line of en- 6 deavor which has to do with a type of lunch packaging wrapper readily usable by the housewife and equally desirable for handling by a workman of the type ordinarily called upon to carry his lunch to the job.

Stated otherwise, the inventive conception has to do with a duplex Wrapper and tie assembly which though usable in other lines of endeavor, for wrapping various types of articles, is most satisfactorily employed, to the mutual advantage of all concerned, when used as a wrapping or packaging device for a sandwich and other articles constituting a so-called working mans lunch.

Indicated along structural lines, the specific embodiment of the invention is characterized by main and supplementary wrappers, wherein the inner wrapper is in the nature of a sheet of Wax coated paper, Cellophane, or equivalent material, and the outer binding wrapper of a more durable, substantially weatherproof texture such as heavy wrapping paper, there being a unique cord binding or tying means associated with these features.

A further feature of the invention has to do with the adoption and use of a tying cord which may be used over and over and which is releasably associated with the outer wrapper and held conveniently in place by a tab-like loop.

Other features and advantages will become more readily apparent from the following description and drawings.

In the accompanying drawings, wherein like numerals are employed to designate like parts throughout the views:

Figure 1 is a top plan view of a structural 40 assemblage perfected in accordance with the principles of my ideas showing the inner and outer wrappers laid flat in readiness for packaging the lunch.

Figure 2 is what may be called a bottom or back plan view of the arrangement depicted in Figure 1, showing to advantage the retention loop for the tying cord.

Figure 3 is a central fragmentary sectional view which may be said to be taken approximately on the plane of the line 33 of Figure 2.

Figure 4 is a perspective view showing the assemblage with the inner wrapper embracing the sandwich or other articles.

Figure 5 is a view showing the completely tied package ready for carrying purposes.

Figure 6 is a view like Figure 5, but calculated to bring out to better advantage the method of tying.

Figure 7 is a perspective view of an assembly type. showing the tensioning rubber strap or band forming a part of the double section tying cord. i

In the drawings the outer heavy paper wrap-, per, which may be of appropriate texture and proportions, is denoted by the numeral 8. Glued or otherwise fastened to this at its center,- as indicated-at 9 in Figure 3, is the'inner companion or complemental wrapper Hi. This is of an area slightly less than the outer wrapper and is preferably of Cellophane, waxed paper, or some equivalent, substantially moisture-proof sandwich wrapping paper. Incidentally, in Figure l, I have diagrammatically illustrated how the sliced or parted sandwich is to be placed at the approximate center of the inner wrapper, after which it is wrapped up around its marginal edges to assume the package arrangement depicted in Figure 4. Then the outer wrapper is brought up around the inner wrapper to form the complete package in a well known manner, as shown for example in Figures 5 and 6. The main thing that we are concerned with here is the provision of inner and outer complemental wrappers of varying proportions and kinds of material,

The tying means for the now folded or wrapped package is essentially composed of three main features. For example, as shown in Figure 7, we are here concerned with a rubber band of suitable length, as indicated at I I. This is preferably reinforced by protective metal clips l2 mounted on opposite apertured ends thereof. These reinforcing cleats. serve to accommodate the knotted inner ends l3 of the two lengths of cord. The outer free ends are denoted, as a matter of convenience by the numerals Id. The outer wrapper, as shown to advantage in Figures 2 and 6, is provided at its center with a retention loop l5 glued or otherwise secured in place, as indicated at Hi. This is preferably a paper loop to render it inexpensive. In practice, therefore, the rubber band is inserted through the loop so that it occupies the approximate position shown in Figure 3, wherein it is properly anchored or retained in position and is also properly located to keep the cords under resilient stress and strain and to thereby maintain the package well tied. The customary method of tying shown collectively or progressively in Figures 5 and 6 is resorted to, whereupon the free ends of the cords are brought together and tied into a readily disconnectible bow knot. Of course, a tying cord of this type can be used over and over. Ordinarily, the package itself is of a disposable paper type, so it is obvious that the papers may be so manufactured as to permit the package to be used repeatedly when not unduly soiled.

The essence of the invention resides in the provision of the interconnected central rectangular sheets of paper forming the inner and outer so-called wrappers, the outer one being durable and the inner one of a substantially weatherproof waxed varietyl In conjunction with this is the double length tying cord characterized the resilient rubber band which provides the dc sired tying action if and when tied as illustrated in Figures 5 and 6.

It is thought that the description taken in connection with the drawings. will; enable. a clear understanding of the invention to be had. Therefore, a more lengthy description is thought uh fifisi irlb l 1 Whi e th r tence. em ment of the invention has been shown and described, it is to, be ndcrstos tha chan es. comi g within the field of invention claimed may be resorted to i des red.-

" I claim:

1. As a component part of a lunch packaging assembly of'the class described, a tying device c mpr si a. n th. of rubber, rein orcin me l. cleats attached to. the. opposite ends thereof, said cleats being apertured, and a of cords knotted a their nn r e s d pas i r u e. pe

tured cleats, the free ends of the cords being adapted to be tied together in the manner and for the purposes described,

2. As a new article of manufacture and as a component part of a lunch packaging wrapper of the class described, a tying unit comprising a length of rubber, reinforcing metal cleats attached to opposite ends thereof, and a pair of tying cords attached at their inner ends to said cleats, the free outer ends of said cords bein adapted to be tied together in the manner and for the purposes described.

3. As a new article of manufacture and as a component part of a tying device of the class described, a length of rubber, reinforcing metal cleats attached tothe opposite ends of said rubher, said cleats being apertured and adapted to accommodate. knotted ends of associated tying cords.

'4. Lunch packaging wrapper means of the class described comprising a substantially rectangular sheet of; rapping paper, a tab. having its. oppo-, site ends fastened to one side of'said. paper, said tabs defining. a retention and guiding loop being located at the. approximate central area, of said sheet, a tying unit comprising arubber band slidably and rele sab y en aged with the loop. and coacting therewith in intersecting relationship; and tying cords attached at their inner ends to opposite ends, of said rubber band in the manner and for the purposes described.
