Abstract
ABSTRACT OF THE DISCLOSURE
A food product such as a bacon analogue or the like is extruded into a pan or tray and a lid or cover is then engaged upon the tray to enclose the product for smoking, cooking and the like. The tray is provided with a downwardly curved longitudinal edge on one side edge and an upturned angulated edge on the opposite side edge. The cover is provided with an upturned curved longitudinal edge on one side edge engaging the upturned edge of the pan and a down-turned angulated edge on the other side edge engaging the downturned edge of the pan. This permits the closed pan to be suspended vertically by the engage-ment of the upturned edges of the pan and cover with a horizontal bar on a hanger on the conveyor trans-porting the pan through the smoking or cooking pro-cess. Further pans and covers may be suspended from the first pan by engagement of the upturned edges of the subsequent pan with the downturned edge of the upper pan. The engagement of the cover with the pan is furthered by the weight of the pan being sus-pended vertically as aforesaid.

, ,: , Proceeding therefore to describe the inven- :
tion in detail, it consists primarily of a pan col- -; 15 lectively de~ignated 10 and a lid or cover collectively ~ designated 11.
,~ , , ,~ ~ "' ', ,~ ,, ~f ,. ,: -"~
~"
1~49~79 In detail, the pan, in this embodiment, in-cludes a substantially rectangular base panel 1~ ha-ving a pair of longitudinally extending upwardly formed side walls 13 and 14, together with one upstanding end wall 15 extending between the ends of the side walls 13 and 14 at one end of the pan or tray. The opposite end is open to facilitate the extrusion of the product (not illustrated) into the pan prior to processing, However, if other methods of filling are provided, then a further end wall (not illustrated) may be pro-vided at the other end of the tray, What are defined as cover engaging means are : provided on the upper edges of each of the side walls 13 and 14.
~he cover engaging means on the upper edge of side wall 13 includes a first longitudinally ex-tending flange 16, extending substantially at right - ;
angles from the upper edge of the side wall 13. his : -flange is then angulated upwardly and inwardly to form a second flange 17 and it then terminates with a third longitudinally extending flange 18 which lies .
substantially spaced and parallel from the first ~-1ange 16, Slotted portions 19 may be provided par-t~cularly in the second and third flanges 17 and 18 " , . ..... .. . ..... . .
, ~: to facilitate the formation of the flanges during - construction.
The means on the upper edge of the other side wall 14 consists of a longitudinally extending flange 20 extending substantially at right angles from the other edge which then curves downwardly and inwardly as indicated by reference character 21, :
,. . " .
through approximately 180 with the inner edge 22 terminating spaced from the side wall 14.
-"
The lid or cover 11 consists of a planar - substantially rectangular main panel 23 with, in this embodiment, one end wall 24 depending downwardly from one end thereof corresponding to the open end of the -tray 10.
" .-. .
~ 15 Pan side wall engaging means are provided - --1~ . , r` on each longitudinal edge 25 and 26 of the main panel : -23 with the means on edge 25 comprising an upwardly - - :
and inwardly curved longitudinally extending portion ~, 27, said curved portion curving through approximately ~ -', 20 180 and having a contour similar to the contour of , the curved portion 21 of the pan 10.
f 104~79 The means on the opposite side edge 26, is formed on an extension of the main panel 23 beyond the vertical edge 27 of the end wall 24 and comprises a first longitudinally extending downwardly and inwardly extending flange 28 and a second longitudinally extend-ing flange 29 extending inwardly from flange 28, but .~ j lying substantially spaced and parallel to the main cover portion 23 and terminating spaced from the ver-tical edge 27 of the end wall 24, Reference to Figure 3 will show the engage-ment of the cover 11 with the pan 10 and it will be observed that the curved portion 27 of the cover wedge-engages with the angulated or flanged portion 16 of ; the pan. At the same time, the angulated flanged ' 15 portion of the cover wedge-engages over the curved : .
portion of the pan 10. When in position, the oppo-site end edge 30 of the cover overlies a relatively --. narrow horizontal flange 31 formed outwardly of the end wall 15 of the pan or tray with the end wall 24 of the cover covering the end edges 32 and 33 of the t~y base 12 and the side walls 13 and 14 respectively thus giving a substantially sealed relationship to the ebclosure with the cover in place which prevents leak-age of product during the treatment thereof by means o a ~mokehouse or cookinghouse depending upon the product being processed.
/
. .
,,,, ', ''~,,, ,,,, , .' " ' ' ;' ' ' " ;, ,, ' 47~9 The wedging ef~ect of the cover with the tray is further enhanced by the method of gu~pe~ding the trays from the conveyor.
Figure 9 shows schematically a portion of a conveyor collectively designated 34 including han-gers 35 normally provided with hooks 36 upon which product is suspended.
However, for this purpose, longitudinally extending rods 37 are secured to the hangers and are spaced therefrom so that the tray and cover combina- - .
tions can be engaged over the horizontally located ;
rods 37 to hang vertically therefrom as clearly shown in Figure 9. ~, .
It will be seen from this view that the weight of the tray and product act vertically and :-assists in the wedge engagement of the tray cover with the tray at the location over rod 37. -It will also be seen that a further tray and cover combination can be suspended vertically rom the lower edge of the first tEy and cover com-blnation with once again the weight of the tray and : . ~ ". , .

product enhancing the wedge action of the cover with the tray~
After processing by passing through the smokehouse or cooking area, the trays and covsrs together with the product therein may either be air cooled or brine chilled as desired, Brine chilling can be used because of the close sealing relationship of the cover with the tray so that brine does not en-ter and spoil or contaminate the contents, - , Once chilled, the cover is easily removed ; by swinging the cover sideways relative to the tray in the direction of arrow 38 (see Figure 1)~ If any --slight product leakage has caused the cover to be-. come adhered to the tray, reference should be made to the cut-away portion 39 shown in Figure 1 which ` is overlapped by a corner 40 of the cover shown in phantom in Figure 1. This overlapping corner por-tion enables the cover to be pried or otherwise jarred from engagement with the tray readily and .: -y 20 easily ~o that the cover can be swung away for re-~ .

It should be stressed that the configuration of the cover engaging side edges of the tray and the side wall engaging edges of the cover permits a wedg-ing and sealing engagement between the cover and the tray when hung vertically as shown in Figure 9.
' .,,, - , ', Furthermore, it is desirable and preferable that both the tray 10 and cover 11 be made from qtain- -less steel for ease of cleaning and elimination of corrosion or any interaction between the food product -s and the tray and cover.
