Abstract: A plastic film bottom tray is held in shape by a rigid bottom rim. A plastic film top is held in shape by a rigid top rim above the tray. Substance to be lyophilized is frozen in the tray. The assembly is lyophilized in a vacuum chamber. Apertures formed between the top and the tray provide fluid pathways for efficient sublimation. After dehydration, the top rim is pushed down into the bottom rim, obliterating the apertures and pressure sealing the two films together in-vacuo.After removal from the vacuum chamber, the two films are heat sealed together, forming a lyophilized product vacuum sealed within a plastic film bag. Rims and film beyond the heat seal are trimmed away.

Abstract: Disclosed are unpressurized multiwall containers of liquid having outer and inner walls of unfoamed plastic material. The plastic container has at least two unfoamed plastic walls, each of which is separated from the next wall by a layer containing a gas or vapor wherein the gas or vapor contains less than ten volume percent oxygen gas and is not reactive with oxygen under packaging conditions. The layer or layers containing the gas can be entirely gaseous or be a foamed or cellular plastic containing, for instance, as little as thirty volume percent gas. The containers have a special utility where it is desired to minimize the permeation of oxygen from the ambient air into the inside of the container. In a particularly important embodiment of the disclosure, the outer plastic layer is supported by a paperboard or wooden container, and the inner plastic container is within the paperboard or wooden container.

Abstract: A container for containment of bituminous products formed by inner and outer flexible casings in intimate contact. The inner casing is of a material which has a softening temperature which is above that of the bituminous product when loaded into the container but below that of the bituminous product when it is applied in use, usually by spraying. This inner casing material has a viscosity at the application temperature which enables the material when melted with the bituminous product to be applied therewith.The outer casing is made from a material which has strength characteristics which enable it to contain the inner casing and bituminous product during the filling of the container as well as during transportation and storage thereof. The outer casing is impervious to movement therethrough of the contained bituminous product, components or additives thereof and preferably has a softening temperature such that melting does not occur at the application temperature.

Abstract: An essentially air tight plastic bag is disclosed, together with a novel method of replacing such bag on the flange surrounding the side access opening of a HEPA filter housing and in accordance with the conventional bag-out, bag-in procedure for removing a potentially contaminated article, such as a filter, from the housing. The novel method includes moving the article through the side access door into the bag, gathering the bag together at a location intermediate the filter in the bag and the open end of the bag, and circumferentially compressing the gathered portion of the bag at two closely spaced apart locations by means of two metal compression bands. The manner in which the bands are applied results in sufficient compressive force at each location to form an essentially solid sealing plug having the appearance and physical characteristics of a rigid, solid rod segment.

Abstract: According to the present invention, the package including a centrally-cored, dish-like container of food having a cover sealed across its mouth is provided in a carton, e.g. made of paper, which encloses a larger space than that occupied by the container of food. The cover of the container of food has regions which may be easily fork-pierced and the carton has apertures overlying these fork-pierceable regions of the container cover. Accordingly, the food may be warmed from a chilled or frozen state by fork-piercing the container cover through the carton apertures for permitting the escape of steam that will be generated in the food during the heating process, and then placing the package, still in its carton, in the microwave oven. As heating proceeds, steam escapes from the food through the pierced holes in the cover and then from the carton through the apertures which overlie the pierced holes.
