Renewed December 24, 1938 1ol claims. (cl. 22o-14) lThis invention relates to 'containers for foodA andthe like, and particularly pertains to a package.

When dispensing various products, such for 5 example as food products, and particularly butter, cheese, ice cream and the like, it is desirable to provide a package within which the product l may be thoroughly wrapped to preserve its davor and to prevent it from contamination and deterioration before it is consumed.l Various cartons have been devised within which such products may be placed, but these cartons are relatively expensive .and consume considerable bulk before they are filled. It is the principal object 15 of the present invention to provide wrapping elements adapted to be cooperatively assembled to form a package within which a product may lbe placed and sealed, the said elements being normally in the form of fiat sheets of material @designed to be folded to receive a product, and

having parts interlocking in a manner to malntain a sealed package Without the necessity of 30 seal the product.`

The invention is illustrated by way of example and in the accompanying drawings in which:

Referring more particularly to the drawings,

The four4 elements previously mentioned are all ofthe elements refragmentary view` in l0 indicates a lining wrapper within which a..

,quired to form the package with 'which the y not'necessary' for the human hand to touch .the

product within the .finally sealed package.

Referring particularly to Fig. 1 of the drawings in which the lining wrapper I0 is disclosed,

. gies to the score marks it will be seen that a central field I4 is formed and is defined by scoring marks I5 which here are shown as defining an octagonalneld. The field 'I4 is bounded by a marginal portion of uniform width whereby a larger octagonal shaped sheet is defined. This-marginal portion .comprises a plurality of rectangular nelds I5 bounded on their innersides by the scoring marks I5 and on their outer sides by an edge I1. The ends of these rectangular fields are dened by parallel.

score marks I I which are disposed at right an- I5. The outer edges I1 continue beyond the score marks I3 to a point of Intersection and a median score mark I9 extends from this point to the point of convergence of contiguous score marks I8. Alternate fields I6 are formed with tangs which extend beyond score marks I1', which marks are a continuation of the marginal edges II of these fields. 'I'he tangs are of a width agreeing with the'distance between score marks I8 and of a suitable length for a purpose to be hereinafter set forth.

A The corners of -the tangs have been cut away at an inclination to facilitate in a sealing operation to be hereinafter described.

Referring more particularly to Fig. 4 of the drawings, it will be seen that the cover wrapper II is shown in detail. The cover wrapper II is in the form of a flat sheet of material and is square in shape. This sheet of material is cut and scored to form a folding structure. An octagonal center field 2I is disclosed bounded on its sides by score marks 22. The size of the octagonal field 2I is slightly greater than the size of the octagonal field I5 of the lining wrapper, since the lining wrapper fits -within the folded cover wrapper as will Vbe hereinafter described. Corner tangs 23 are formed as a part lof the cover Wrapper and occur at the corners of the square blank of the cover wrapper. These tangs are defined by marginal edges 24 which are the corners of the blank. 'Ihe edges 24 terminate in shoulders 25 disposed at right anglesthereto. tend inwardly toward leach other Auntil they intersect the edges whichemanatefromand are at right angles to score marks :22. The scoremarks 22 as previously stated deflneathe config uration of the octagonal field 2i. The edgesl are parallel to each other and are apart a distance equaLto the length of a score mark 22.` Formed parallel to the score marks 22 and extending from the inner` end of one shoulder 25 to a complementary shoulder 25 is a scoremark 2l provided for a purpose to be hereinafter set forth.

occurringbebween the corner tangs 23 are side folds `2l which have an outer edge A23.

being continuations of edges 24 of the tangs 23. The length of the edges 23 represent Vthefdistance between shoulders 25 on adjacent corner lfilings A23. The folds 2l are defined along their inner Vedges by" previously mentioned score marks v22.

Two score marks 3l extend from the ends of the score mark 22 tothe outer edge 2! and divide the folds n inw three sections rectangular center section 3i and two end flaps 32. The end flaps areofa tionsupplementalto thatof ashoaxlder 25 and aside 25 ofamrner tang 23. Cut into eachofthe rectangularsections 3i isa slit 33 whichis paralleltotheouter marginaledge 2l andisalsospacedreiatively close thereto. This slit extends fora maior length of thedistance between the scoremarks- 3l and adjacent to its ends'are small right angle slits 24.1 These members receive tang: of a part hereinafter to be The shoulders 25 ex' arcaoco Referring to 213.49 or the drawings the top sheet I2 is disclosed. This is a square ilat sheet having vdiagonal scoring marks across its corner portions so that the marginal edges and the scoring marks willdeflne an octagonal s' tions being scored transversely at 3l so that the 15 score marks 38 and the marginal portions of the edges of the blank will'form an octagonal field 39 substantially that of the octagonal field 2I oi the cover wrapper.' Corner tan'gs 40 will thus be formed. These tangs have marginal edges 4I zo disposed at right angles at the corners of the blanks and locking shouldersv 42. The overall distance from the juncture of the marginal edges 4I and the locking shoulders 42 is slightly less than the length of the slits 33 in the cover wrap- 25 per I I. The width between the inner ends of the shoulders 42 on the tang substantially agrees with the distance between the short slits 34 on the cover wrapper I I,..so that these parts will be locked together.

In forming a package with the lining Wrapper I0. the top lining sheet I2, the cover wrapper II, and the cover top sheet I3, the following rprocedure is preferable. A mold 45 is provided having a cavity same configuration as the center fleld I4 ofthe lining wrapper, the dimensions, however, being slightly greater than. the dimensions of that field. A plunger 41 is provided to operate in conjunction with themold 45. The lining wrapper Il is n then suitably positioned over the cayity inthe mold, as shown in Fig. 2, after which the plunger 46 therein. This cavity is of the 35 formed {containenand the marginal portinnsvii a,

will fold' upf along the sides to provide the sides of an octagonal-wall structure. The tongs 2l will extend upwardly'v around. the edges of the container thus formed and the portions oi the blank occurring between the adjacent-rectangular n sections Ii will be folded upon themselves, as indicated at '43 in 3l and 131. The outer coverwrapper it isthenplncedinasimilarmold 45` and folded-from the position shown in Fig. 5

` It will thus be seen that the package here disclosedV is formed by theause of inexpensive .flat sheets of suitable materiallwhich do not require the use of expensive machinery .or preforming dies in making a container, but make it possible for a package to be made and assembled progressively as the parts are folded andas the food product is deposited therein and sealed.-

It will also be evident that due to the shape of the package formed it may be placed in a storage space, such as a mechanical refrigerator, either fiat or edgewise, since it occupies asmall space and can be conveniently packed in with other containers.

While- I have shown the'preferred form of my invention, as now known to me, it -will be understood that various changes might be made in the combination, construction, and arrangement of parts by those skilled inthe art, without departing from the spirit of the invention as claimed.

-Havingy thus described my invention, what I claim and desire to secure byLetters Patent is:
