Application March so, 1948,, Serial No. t-ass cranes, whee 17 9 This invention relates tb'the p ckagingbfpieomargai'in'e and to the coloring of tn-seam; The i'nye'nti'on is particularly usefu in corm on with the pac agihg 'df iififio l'oid "ol'fifnai'garine in such a manner as to perm-tits e ng, bred by the consumer without removing the mesmerga'rine from the pajclr'alge Present day ackages 1'01 uilolbre'd creamer-=- garine are accompanied by separate devices "or packets containing coloring material. When e01: oring material accqmpa'nies the packa'ge of uhcolore Olen margarine, the problems and ease of packaging are much greater than when no colorihg material accompanies the 'p' rage; Siich' packages also can be somewhat unsightly after the coloring o eratio is 'co'rnpleted if the housewife oes not use all of thefc'oloring material or if the coiormgmaterial itself dyes the wrapper.
An object of the present invention is to protide a packageror uncolor'ed oleomar garihefigvith; out any accompanying color, yet which will ehable the housewife to color the e eomarga in without removing the wrapper. A f th'er object is to package oleoinarg'arine inc, 151c, se'alejd wrap-per to which segments spawnar strip of manner, the characters: which; w'iirp eimit easy passage for aninjection heed egwme at the same time will retard or pfieyent the of qiesaargariae after the needle is wit p by the sen-sewing of'the hole made by'th e needle.

Yet another object is to provide the housewife with a sealed package of uh-colored 'ole'omargarine and' with means for-injecting color into the oleomargarine at seyeral places, thus facilitatin' g' the speed with which theoleomarg" may e colored in'the kne'adinstep. l A thei' object is to "providea packager oleomar'garinein which the Efostafid labo' taching coloring material is eli" nated, the same time providing a s aled sit I equip ed with means for sealing an teas ng formed by an injecting needle to pefifiit the thorough kneading of the oleomargarine without egress of oleomargarine during the kneading operation. Other specific objects and advantages will appear as the specification proceeds.

In the illiistration given, it designates-a wrapper enclosing a body of oleomargarin H. The wrapper [0 may be formed at trair'slu nt material, such as; for xamp e; synthetic his 15, vinylit'e material, "etc, 'I prefer toemploy amaterial which is translucent 'so to permit and ma te sired, thew a pai l e 1 Sheet'anathe edges thereof my be a can; of bl'e'o fnargafilne and the" abutting edges then-sealedtog'ethei' ts'raris a By employing same as tire sans 5f heatfe'le etric appiicati' Tdthe'wi" pperlil'farid 'fifeiierjabiy pear to wire that it'flle'd with a e 5a, 1 2 of sen-sea ng ate 159 595611 g-i ra her, an 5 rubber 'ceinent,
have found that excellent patches are pron ed by the sponge or foam rubber and alsq b ma mart nis iatmg' A V other adhesive resilient cements, or by heat sealing, etc.
The patch l2 may be attached to the inside or to the outside of the wrapper, and it may cover a small portion or constitute all or any part of the 3 wrapper itself. It will be suficient for the present purposes to illustrate the patch as applied to one side of the package.
Any means for injecting coloring material into the oleomargarine through the patch may be employed. In the illustration given, a conventional syringe I3 is shown equipped with a hollow needle l4, which is passed through the sponge rubber patch 12 and the wall of wrapper [0, as illustrated in Fig. 2. By this means, coloring material in liquid, powder, or other fluid form may be introduced through the needle and into the interior of the oleomargarine. The needle permits the injection of coloring material at points extending transversely of the package and also in the distant end portions of the package, if desired. This is accomplished merely by swinging the needle to the right or to the left through the single opening shown. If desired, the package may be equipped with several patches to permit injection at various points about the package. After the desired amount of coloring material has been introduced deeply into the interior of the oleomargarine, the needle I4 is withdrawnrand the opening formed thereby is sealed by the foam latex or sponge rubber patch 12. The package may then be manipulated in a kneading operation to quickly mix the coloring material with the oleomargarine. By reason of the wide distribution of coloring material in the oleomargarine body, the mixing step requires little time to brin about the uniform coloring of the oleomargarine mass.
By the method described, it is found that the coloring material is evenly distributed and that there is no tendency for a spot of colorin material, unmixed with oleomargarine, to be present at any particular point about the wrapper. Instead, all of the coloring material is mixed with the oleomargarine.
After the kneading operation described, the package is again shaped by pressing it along the sides and ends and is preferably restored to the original box container in which it was purchased. The material forms an even rectangular block upon being restored to the refrigerator within such container. Later, as the oleomargarine is kneaded, the package may be cut through by a knife and the portion of the severed wrapper removed as its contents is placed upon a dish.
In the coloring material injecting step, it will be understood that any pump and needle structure may be employed. A hollow needle fitted to a plunger pump of any type will be sufiicient for injecting the coloring material through the patch and into the oleomargarine interior.
While, in the foregoing description, I have set forth a package structure and method for colorme: in considerable detail for the purpose of illustrating the invention, it will be understood that such details of structure and method steps may be modified widely by those skilled in the art without departing from the spirit of my invention.
