7 Claims.
This invention relates to improvements in package for food products.
In the merchandising of various greasy food products, for example, lard, doughnuts or fried cakes, the grease frequently seeps through the wall of the package, rendering it unappetizing and unsightly. Packages having strictly greaseproof walls are not generally practicable on account of the expense thereof.
The main object of this invention are to provide an economical package for the merchandising of food products which is not rendered unsightly or .unappetizing by penetration of grease and does not assume an objectionable spotted appearance as a result of grease seeping therethrough in spots.
A further object is to provide a package having these advantages which may be very coonomicall produced. v
Objectsrelating to details and economies of the invention will appear from the description to ably treated with wax.
inders 9 and i0 and the fibers for the outer layer being deposited by the cylinder II.
The container-board may be built up as desired, that is, it may be laminated or of uniform composition throughout. A very satisfactory furnish for the cylinder II is 75% bleached sulphite fiber and unbleached sulphite fiber with which has been thoroughly mixed or inat ll, through the tank and discharged between follow. The invention is defined and pointed out Fig. l is a perspective view of an open food package embodying the features of my invention, a plurality of fried cakes being conventionally illustrated therein.
Fig. 2 is an enlarged fragmentary section on line 2--2 of Fig. 1.
Fig. 3 is a fragmentary view of a cylinder type paper machine which may be used for the manufacture of container-board stock which I preferably employ.
Figure 4 is a conventional illustration of an apparatus for applying wax.
Referring to the drawing, the container I is formed of a suitable blank, preferably one which can be set up without gluing. The details of the blank are not illustrated as the structure may be very greatly varied. I 5 p The end flaps 2 are adapted to be folded inwardly after the contents, as for example doughnuts conventionally illustrated at 3, are placed in the container and the cover 4 closed, the cover having a tucking flap 5.
The container-board or material indicated generally by the numeral 6. Fig. 2, comprises an inner layer I and an'outer layer 8 fully integrated or formed by depositing the fibrous stock as indicated in Fig. 3 in whichthere are a plurality of forming cylinders 9, l0 and I1, the ilbers for the layer I being deposited on the web I! by the cylthe pair of rollers from which it is delivered through a pair of squeezing rollers l5. Suitable means are known in. the art for treating the out-' side only with wax. This wax, preferably paraffin wax, is not resistant to grease and its use is not designed to render the package or container grease-resistant, but its use does substantially add considerably to the appearance of the product in use, that is, while it darkens slightly the white outer layer 6, it minimizes the spotting resuiting from the penetration of grease from the contents of the container.
My improved package is very attractive, but
the main advantage is that it does not become so discolored or spotted by the penetration of grease in restricted areas as to become unattractive and unappetizing in appearance. I have illustrated my invention in a simple embodiment thereof. I have not attempted to illustrate other embodiments as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may be de-- sired. l
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
, 1. A carton container suitable for greasy food products and the like formed of fibrous-board stock having inner and outer integrated layers of paper stock fiber. the outer layer being formed of a furnish comprising bleached sulphite, 25% unbleached sulphite and having between 2 and 10% titanium oxide incorporated therewith,
the container-board being waxed.
2. A semi-rigid package suitable for greasy food products formed of container-board stock having inner and outer integrated layers "of-paper stock fiber, the outer layer containing titanium oxide in such proportion as to substantially reduce the discoloration thereof from'greasy seepag'eor transfer through the wall of the container, the package being waxed on its outer surface only.
8, A semi-rigid package suitable for' greasy food'products formed of container-board stock having inner and outer integrated-layers of paper'stock fiber, the outer layer containing titanium oxide in such proportion as to substantially reduce the discoloration thereof from greasy seepage or transfer through the wall of the container.
\ 4. A semi-rigid package suitable for greasy food products formed of fibrous-board stock having an outer layer containing a light refracting material 'of relatively high index in such proportion as to substantially reduce the discoloration thereof from greasy seepage or transfer through the wall of the package, the package being waxed on at least its outer surface.
ing an outer layer containing a light refracting gamers a material a relatively high index in such rrobortion as to substantially reduce the discoloration thereof from greasy seepage or transfer through the wall of the package. d 8. A semi-rigid package suitable for food such as fried cakes or doughnuts adapted to receive a row of doughnuts or fried cakes arranged side by side and with portions thereof contacting with the wall of the package, the walls of the package being formed of fibrous container-board. the surface portion of the container-board stock containing titanium oxide in such proportion as to substantially reduce the discoloration thereof from grease seepage or transfer through thewall of the package, the outer surface being treated with mix.
7. A semi-rigid package suitable for food such taining titanium oxide in such proportion as to substantially reduce the discoloration thereof from grease seepage or transfer through the wall of the package.
