y 1956 R. s. STEINBOCK OLEOMARGARINE MIXING PACKAGE Filed Aug. 4, 1951 INV EN TOR. fioberg 5. Ste/aback United States Patent Q OLEOMARGARENE MurrNu YACKAGE Robert S. Steinbeck, Sarnia, Ontario, Canada, assiguor, by mesne assignments, to Hammock Package Ltd, a corporation of Canada Application August 4, 1951, Serial No. 240,424

1 Claim. (Cl. 99-179) This invention relates to flexible sealed type containers for packaging soft plastic substances and to a method and means for utilizing such a container to mix the original contents thereof with additives without permitting leakage of the contents.

Presently used packages for uncoloured oleomargarine are sold with separate devices or packets containing colouring material accompanying or attached to the oleomargarine wrappers. When colouring material thus accompanies the package of uncoloured oleomargarine, the packaging problems and costs are a good deal greater than when no colouring material accompanies the package. With such packages, if the housewife does not use all of the colouring material, or if the colouring stains the wrapper from long contact with it, the resulting package containing the coloured oleomargarine may be quite unsightly.

Furthermore, with present-day packages for uncoloured oleomargarine in which the contents are sealed, it is impossible to control the degree of colouring. A given amount of colouring material is sealed within each package and this amount controls the degree or density of colour in the coloured oleomargarine which results after mixing. Thus the housewife is forced to accept the colour standard set by the manufacturer regardless of her own preference in the matter.

An object of this invention is to provide a sealed flexible package for soft plastic substances, having means permitting entry of an additive into the contents of the package whereby the additive may be mixed with the contents without destroying the sealed condition of the package. 7

Another object is to provide a sealed flexible package for uncoloured oleomargarine containing or accompanied by no colouring material in physical contact with the package, yet so constructed that one may add colouring material to the oleomargarine within the package and mix the colouring material with the oleomargarine by kneading the flexible package without destroying its sealed condition.

A further object is to provide a package for uncoloured oleomargarine and means for inserting colouring material into the sealed flexible package, which will allow the housewife to control exactly the amount of colouring she wishes to add, while at the same time enabling her to mix the oleomargarine with colouring without removing it from the package.

The invention thus contemplates the provision of a package for uncoloured oleomargarine having an aperture in the wall thereof, sealed with a removale tape, through which may be introduced colouring material in any amounts desired by the housewife.

More specifically, the invention contemplates the packaging of oleomargarine in a flexible sealed wrapper having an aperture over which is attached a strip of pressure sensitive tape, the construction being such that the tape may be peeled back to permit passage of colouring material through the aperture and then re-attached to prevent the egress of colouring or oleomargarine while the two are being mixed.

Other details, objects and advantages of the invention will become apparent as this description proceeds.

The invention will be described with reference to the accompanying drawing, in which Figure l is a perspective view of a package embodying the invention,

Figure 2 is a partial sectional View on line 2-2 of Figure 1,

Figure 3 is a perspective view of the package showing a manner of inserting the additive into the contents of the package, and

Figure 4 is a perspective view of the package in rescaled condition subsequent to insertion of the additive.

Referring to the drawing, 10 designates a wrapper enclosing a body of plastic substance such as oleomargarine 11. The wrapper 10 may be formed of translucent, thermoplastic material, such as, for example, chlorinated rubber, polyethylene, vinyl, vinylidene chloride, and a large number of other well-known packaging materials. A translucent material for the wrapper is preferable because it permits the housewife to see the progress of the colouring operation. At the same time the wrapper is preferably flexible and strong enough to withstand the kneading and mixing operation without breaking. The wrapper 10 may be tubular and may be sealed at one end and then filled with oleomargarine, the other end then sealed. If desired, the wrapper 10 may be in the form of a sheet and the edges thereof may be drawn about a cake of oleomargarine, and the abutting edges then sealed together to form a closed package. By employing the thermoplastic materials mentioned, the sealing may be effected by the application of heat, electric current, or the like.

The wrapper 10 is provided prior to filling with an aperture 12 in the wrapper wall, and the aperture sealed over with a strip of pressure sensitive tape 13. In the illustration given the aperture is a simple straight slit in the wrapper wall as shown in Figures 1, 2, and 4. Although it is preferable to provide the aperture 12 prior to filling the wrapper, if desired, the aperture may be formed after the wrapper is filled.

However, the aperture may be of any design and shape to accommodate any method or means used for carrying and inserting the colouring material.

The pressure-sensitive tape used in the illustration is of a type well-known in the art. It may or may not be translucent. Preferably it is flexible so as to flex and bend with the wrapper wall while the kneading and mixing operation is in progress. The adhesive used to secure the tape to the Wrapper may be of any type suitable to achieve both proper adhesion upon pressure and release upon pull by the consumers hand. When foods, such as oleomargarine, compose the contents of the pack age the adhesive on the tape is, of course, non-toxic and grease-resistant.

The tape may or may not be provided with a pull-tab 14, which is a folded-over or end section of the tape free of adhesive. This is best illustrated in Figure 3 where 14 shows an end strip of the tape peeled back and free of adhesive and 15 shows the main body of the tape covered with adhesive material.

Any means for carrying and introducing colouring material through the aperture may be employed. In the illustration given the colouring material is in the form of powder compressed into a tablet 16 as shown in Figures 3 and 4. A tablet is an easy and clean method for carrying and introducing colouring material into oleomargarine. All or part of the tablet may be used depending on the density of colour desired in the coloured oleomargarine; a tablet of powder dissolves and disperses 3 quite rapidly in the oleomargarine. The beginning of such "dispersion, before the mixing operation has 'c'ommenced, is shown in the dispersion lines 16a in Figure 4. During the mixing operation the colouring material disperses quickly, evenly, and completely throughout the oleomargarine.

After the tablet has been inserted through the aperture and the'tape resealed'over the aperture, the package may then be manipulated in a kneading operation to quickly mix the colouring material with the ole'omargarine. The tape, being flexible and Well sealed over the aperture, the mixture operation can be undertaken vigorously with no fear of breakage or leakage.

After the kneadin and mixing operation the package may be restored to its original uniform shape by pressing the wrapper to fit its original linesv Then the oleo margarine may be chilled and firmed, and when ready to serve the wrapper may be cut with a knife and peeled free from the oleomargarine.

One of the uniquely novel features of my package is the many optional methods which may be used for carrying the additives which are to be introduced into the package through its aperture-pressure-tape structure. Through the aperture of my structure the additive may be inserted in the form of a solid, powder, liquid, or paste,

any of which may be in a compact or loose form, or

they may be coated, compressed, or enclosed within a capsule or packet. For example, the colouring material maybe inliquid form enclosed within abreakable capsule. if the capsule wall isnot miscible with or permissible within the package contents, the capsule may be constructed with a flange or projection extending outwardly from its wall. The main body of the capsule might then be inserted through the aperture of the wrapper with said flange lying fiat upon the outside wall of thewrapper around the aperture. The pressure-sensitive tape could then be pressed down upon and sealed over and around the capsuie and its flange thus anchoring the capsuleto the wall of the wrapper and preventing it from escaping into the package. The capsule could then be broken with fin er pressure, releasing the colouring contents from the capsulefcr mixing with the contents of the package.

The aperture in my package structure may be of plural number, ofany size and shape, and located at any number of places or at any place in the wrapper wall. Thus, if exceptional speed is desired in the mixing operation, an aperture could be located at both ends and-in the middle of my package, and colouring material could be introduced at three S'frafe'gic points into the eleomarga'rine.

Such a structure might be very desirable, for example, in a package containing two or more pounds of oleomargarine.

While, in the foregoing description, I have set forth a package structure and methods for introducing and mixing additives with the contents of'a package in considerable detail for the purpose of illustrating the invention, it will be undesrtood that such details of structure and method steps maybe modified Widely by those skilled in the art without departing from the spirit of my invention.

I claim:

A mixing package for the coloring of oleomargarine comprising a wrapper'of a flexible and translucent material adapted to be sealed about a body of oleomargarine, a body of oleomargarine sealed within said flexible Wrapper, said wrapper having a wall provided with a single straight slit normally having contiguous edges, said slit adapted to admit solid coloring material therethrough for the mixing of said coloring material with the oleomargarine, and a flexible tape covering said slit and being provided with a pressure-sensitive adhesive securing said tape upon the surface of said wall about said slit, said tape being removable so that a desired amount of coloring material may be inserted through said slit for mixture with said oleomargarine, and also being reattachable to reseal said slit and to retain said oleomargarine and coloring material within said wrapper during mixture thereof, and wherebyadditional amounts of coloring material may be inserted through said slit following a kneading operation until a desired color intensity of the oleomargarine is obtained.
