Abstract: Frozen dessert cones made from a cooked batter capable of having lower and higher moisture contents, which respectively cause the cone to assume dimensionally contracted and expanded states, are provided with sanitary jackets while in their dimensionally contracted state. When the cooked batter forming the cone attains a higher moisture content, the cone will dimensionally expand against the walls of the sanitary jacket thereby exerting a restraining force against removal of the jacket from the cone. The sanitary jacket is applied to an interior handle region of a cone so that the sanitary jacket will nest with the exterior surface of a downstream cone handle when stacked therewithin. A chute is provided so as to align and direct the sanitary jacket with respect to the interior handle region of the cone. A stream of pressurized fluid (e.g., air) is then preferably directed against the sanitary jacket so as to propel the same into a seated relationship with the interior handle region.

Abstract: A method and apparatus for loading a refrigerator box which has a door along one side and insulation in all of the surfaces of the box including the bottom. The invention specifically relates to devices for loading the box using a pallet loaded with prepackaged material such as ice.

The transportation device is then removed and a piece of insulation is inserted under the pallet.

Abstract: A system for recovering, selecting and recycling empty containers returned after use which includes two specific sequences. In the first sequence, a container (4) passes a door (2) to remove material of a different type, while the accepted product activates a microswitch (9) for counting and activating a warming device to blow in hot air onto the same material which is thus softened; the container is then pushed between a motor driven heated pressing roll (18) with tension supplied by sliding contacts (22) to carry out a compact and permanent pressing by using pressing-welding points and another inertia roller (19). Knives (24) cooperate with the two rollers to ensure the separation. In the second sequence or selection phase, recovered bodies (29), are applied from hopper (30) and fall onto a feeding system with vibrating canals, to maintain the containers individually; photocells (34) check that no superpositions occur.

Abstract: A beverage package and a method of packaging a beverage having gas (preferably at least one of carbon dioxide and inert (nitrogen gases) in solution has a non-resealable container 1 within which is located a hollow pod 4 having a restricted aperture 7 in a side wall. The container is charged with the beverage 8 and sealed. Beverage from the main chamber of the container enters the pod 4 (shown at 8a) by way of the aperture 7 to provide headspaces 1a in the container and 4a in the pod 4. Gas within the headspaces 1a and 4a is at greater than atmospheric pressure. Preferably the beverage is drawn into the hollow pod by subjecting the package to a heating and cooling cycle. Upon opening the container 1 by draw ring/region 13, the headspace 1a is vented to atmosphere and the pressure differential resulting from the pressure in the pod headspace 4a causes gas/beverage to be ejected from the pod (by way of the aperture 7) into the beverage 8.

Abstract: The invention relates to an arrangment for the continuous heat treatment and packaging of a liquid product with the object of sterilizing the product, the product being heated for a short time together with, and surrounded by, the packing material wherein it is to be enclosed.

Abstract: A measured amount of water is frozen in a tray and cubed. The cubes are dropped directly into a bag placed under a chute. The ice drops responsive to the defrosting of the tray which releases the cubes. When the defrosting cycle of the ice maker is complete the tray moves up which moves an attached chain up to unclog any ice jam in the chute. Then the freezing of the ice begins again, a bag-carrying platen moves away from the chute and the bag is heat sealed. The bag, full of ice, is then released and dropped into a cold storage bin below the bagging mechanism.

Said temperature reduction is preferably achieved by filling the receptacle so that the food therein is flowable or mobile and then tumbling the receptacle in a cooling medium so that the food flows or moves within the receptacle. After storage at 28.degree. F. to 32.degree. F., the food may be heated by tumbling the receptacle in a heating medium in order to bring the food quickly to serving temperature thereby avoiding overcooking.

Abstract: A method and apparatus for packaging thermoplastic fluid material is the subject of the present invention. The thermoplastic material is mixed at an elevated temperature and emptied in predetermined batch quantities into a holding area. A gate in the bottom of the holding area is operable to empty the batch of material in a very short time span. A plurality of heating elements are disposed beneath the outlet of the holding means and are maintained at a temperature high enough to cause parting of the fluid material as it passes over the heating elements. Thus the batch of material from the holding area will be divided into a plurality of individual masses as the material passes over the heating elements. By utilizing a number of heating elements equal to one less than the number of containers to be filled, and by spacing the heating elements equi-distances apart, the individual masses of material will be equal in size and the number of individual masses will equal the number of containers.
