Abstract: A wrapping device having a laminate film is disclosed. The laminate film includes at least a pair of outer layer and inner layer comprising synthetic resin layers non-heat-fusible relative to each other, a bonded portion through which the outer layer and the inner layer are bonded to each other by bonding means and a non-bonded portion where the outer layer and the inner layer are separated from each other. A communicating passage is formed at the non-bonded portion by the inner and outer layers. A communicating construction is provided to the inner layer at the non-bonded portion, the construction allowing communication between space facing the inner layer and the communicating passage.

Abstract: The disclosure relates to an aseptic bag (1) for separating off liquid. The bag comprises a tight outer bag (2) and a perforated inner bag (3). Each bag (2, 3) consists of two parts (4, 5, 6, 7). In the first bag part (4, 6) of the outer bag (2) and the inner bag (3), there is disposed an inlet device (12) and, in the second bag part (5, 7), there are disposed closure means (13) which may rigidly engage with the inlet device (12). In addition, there is provided in the first part (4) of the outer bag (2) an outlet device (18) and corresponding closure means (19) in its second part (5). An inlet valve (14) is connected to the inlet device (12) and an outlet valve (22) is connected to the outlet device (18). The product, solid particles mixed with a carrier liquid, is filled through the inlet valve (14) into the aseptic bag (1). The solid particles will then remain in the inner bag (3), while the liquid will continue through the perforations in the bag (3) and be separated through the outlet valve (22).

Abstract: A bag assembly for containing material requiring handling and compaction, such as household waste products, is provided that includes bags that are nested one within another to produce a double-walled structure. Gussets and folds are also provided which are temporarily held together by restraining means such as adhesive to provide a first, smaller bag volume for a waste container. A bag restraining lid is removably positionable over the open end of the container, which includes a container lid thereon for accessing the bag assembly. The adhesive is adapted to break away when the bag assembly is compacted so that it assumes a second, larger volume and thereby minimizes the chance that the bag assembly will be ruptured during the compaction process. In an alternate embodiment, the bag assembly may be supported by a rack, frame, or hook. In a still further embodiment, the bag assembly may be a single-walled rather than a double-walled structure.

Abstract: A changeable label pad has a base label layer which can be adhesively attached to a recording media container. A first adhesive having a first strength attaches the base label layer to the container. At least two label segments are attached to the base label layer. The label segments combine to cover most of the base label layer and the label segments are separated from each other. A second adhesive having a second strength which is weaker than that of the first adhesive attaches the label segments to the base label layer. The total area of all of the label segments in a layer of label segments is less than the total area of all of the label segments in an underlying layer of label segments.

Abstract: A packaging container comprises a foil laminate comprising at least two layers in which openings are formed. The two layers are joined together over their entire surface area, except for in a striplike channel. A valve strip is disposed in the channel and in valvelike fashion covers the openings of the inner layer. If there is an overpressure in the packaging container resultant gas can escape into the open through the openings and the valve strip acts like an overpressure valve. As a result of the specialized disposition and embodiment of the valve strip and of the openings, a reliable escape of gas produced is achieved.

Abstract: An improved bone-guard bag for packaging meats and other foods for longer term preservation during storage and transport, comprising an oxygen and moisture-impermeable outer bag and a puncture-resistant inner bag for preventing bones and other sharp surfaces of the packaged food from penetrating the inner and outer bags to compromise the oxygen and moisture-resistant integrity thereof. Vent means are provided in the bone-guard bag to permit oxygen evacuation, gas flushing, and sealing of both the inner and outer bags simultaneously. The inner bag is secured to the outer bag to allow movement relative to each other, while facilitating insertion of food therein. The outer bag is preferably made from a coextrusion of separate polyethylene and nylon layers bonded together. The inner bag is preferably made from at least two unbonded plies of polyethylene film for increased puncture resistance.

Abstract: A flexible intermediate bulk container has a liner which is provided with one or more hollow suspension members for fastening the liner to an outer container in correct relative position. The suspension means members form vents for expulsion of air from the liner during and subsequent to filling with particulate bulk material. The suspension members are preferably tubular to provide vents for the interior of the liner. Such vents may be controlled by one-way valve devices.

Abstract: Packaging in the form of disposable, low cost bags for cooked foods, such as chicken, fish, seafoods and hot baked specialties like pizza maintain the food in a hot crisp and appetizing condition until consumed with little or no sogginess occurring due to being in contact with water vapor/steam, condensate or residual cooking oils/fats. The bags have a nonlaminated multi-ply film composite consisting of at least a nonporous outer ply and an inner porous ply as a liner. The plies are spaced so as to provide a gap in the form of enclosed fluid reservoir for collecting and separating fluids from the food for maintaining crispness with little back flow of condensate and oils to the food compartment. Special materials and pads for absorption and retention of such fluids may be eliminated.

Abstract: A flexible storage container for the transportation of liquid foods, such as orange juice, includes an outer tear resistant shell having a linear closure in a front or end face thereof, and a replaceable inner liner which is inserted into the outer shell through the closure. The outer shell further includes a vent through which air can escape from the space between the inner liner and outer shell. The inner liner includes a filler fitting which is fed through the outer shell. The container is characterized in that it is elongated in shape and has a front or end face that bulges to conform to filling pressure. The front or end face is reinforced by a flexible bar that extend essentially perpendicular to the base. The container is further characterized in that the closure, and fittings for filling, emptying and venting are located in the front or end face.
