Specification of Letters Patent. Patented M 28 1922 Application filed June 17, 1921. Serial in). 478,288.

To aZZ whom it may concern:

.Be it known that I, EDWARD J. RETZBAOH, a citizen of the United States, and residing at St. Louis, Missouri, have invented a new and useful Improvement in the Art of Making and Packaging Pastry, of which the following is a speclfication.

This invention relates to the art of making and packaging pastry for delivery to the ultimate consumer.

One of the objects of this invention is to evolve a process whereby the pastr is baked in the package'in which it is delivered to the ultimate consumer, in such a manner as to simplify the baking operation and deliver the product in convenient and desirable form.

Another object is to provide a merchantable unit in which the baked pastry is enveloped and protected, andwhereby it can be readily taken out of the box without breaking the baked pastry.

Further objects will appear from the detail description taken in connection with the accompanying drawing, in which:

Figure 1 is a sectional view of a unit embodying this invention; and

Figure 2 is another view showing the manner in which the box is taken from the baked pastry.

Referring to the accompanying drawing, the: box 1 is formed of paper or any other suitable material of that nature; it is, therefore, to be understood that the word paper as applied to .the material from which the boxes are made, is intended as a. word of general description and not of limitation, but to include paper or like non-metallic materials which are commonly used for such purposes. This box is provided with a liner 2, which may be formed of grease-proof or vegetable parchment or any other suitable material adapted for this urpose. This liner is loose in the box and is preferably formed of a single sheet of proper shape and conforming to the inside of the box. This liner is, however, attached to the box along its upper edges only, and preferably by folding the edges of the liner over the edges of the box as shown at 3 and pasting the same along the outside faces of the box along its upper edges. This leaves the liner loose in the box and attached only along its upper edges. The cover 4 for the box may also be formed of paper or any other suitable metal receptacle.

has been baked in the box the cover is placed thereon, thereby forming a merchantable umt. In some cases it may be desirable to cover the box during the baking operation; in such case the cover and its lining is placed on the box and the product is then baked in the filled and covered box.

It will, therefore, be seen that in accordance with this invention there is provided a merchantable unit which is ready for delivery to the ultimate consumer. B baking the product in a lined'box not only is this product enveloped; by a sanitary envelope, but the bakedproduct can also be removed readily from the box, as the product does not stick to the box either in the baked or unbaked semi-fluid state as is the case where metal and lined metal boxes are used. This removal can be simply accomplished by removing the cover and inverting the box, when it can be raised from the roduct, the liner peeling off as shown in igure 2, in view of the fact that this liner is entirely loose from the box except that it is attached thereto along its edges; the product, there-' fore, remains whole and unbroken.

In view of the fact that the lining engages the box along its edges, filling thereof is facilitated, so that the semi-fluid product does not fall between the box and its lining, which may otherwise cause charring and a hesion as well as improper baking when the box is placed in the oven. It will also be noted that the attachment of the lining is such as to keep the paste securing this lining wholly out of contact with the product enveloped thereby, either directly or indirectly through the lining.

In accordance with this invention, the product is baked in a lined paper box as distinguished from a metal receptacle or lined In a metal receptacle, the product will not only invariably adhere to the metal enveloping the same, but the baking is also ununiform, as the tendency isfor providing an insulating covering preventing the outside to become baked rapidly, thereby thorough baking of the interior. This difiiculty is not overcome by lining a metallic box, because not only is there thena tendency of the lining to become charred, but there is still a tendency to burn the outside or bake it hard, while the inside remains undone, In the lined paper box, however, there is no tendency of the lining to adhere to the box body, nor is there a tendency of the lining to become charred. This is for the reason that the box itself as well as the lining is a poor conductor. of heat, and accordingly the baking will be gradual from the outside to the innermost parts of the roduct enveloped b the lining and by the ox. Accordingly .t ere is no tendencyof the outside becoming burnt, charred oreven overdone but the baking will be uniform throughout, while the exposed top can .be properly browned as is desired.

It isobvious that various changes may be ers, t e prooess'comprisi thus. described the invention, what paper boxwiththe product, and baking the product while in the filled box, substantially as and for the [NW set forth.

2. In the art of making and packaging pastr for delivery to the ultimate consumfillin a lined paper box with the prouct; ba g the product while in the filled box, and placing the cover on the filled box, substantially as and for the purpose set forth.

3. In the art of making and packaging pastr for delivery to the ultimate consumers, t e process comprising, filling a paper.

box with the-product placed inside and enveloped by a loose liner attached to the box at its upper edges, and baking the product while in the filled box, substantially as and for the purpose set forth.

4. A merchantable unit comprising, a lined paper box enveloping and pastry which has been "substantlally uniforml baked in the box, substantially as and or the urpose set forth.

protecting 5. A merc antable unit comprisin a pag .per box having a loose liner attache to the box at its upper edges, and enveloping and protecting pastry which has been substantially uniformly baked inthe box, substantially as and for the-purpose set forth.

- In testimony whereof I aflix my signature this 23rd day of May, 1921.
