  • Patent number: 5866184
    Abstract: A package is capable of enclosing a food product in two different gaseous atmospheres at different times. Initially the food product may be packaged in a low oxygen atmosphere in order to prolong the shelf life of the product. When it is time to sell the product for example, it may be desirable to supply oxygen to the food product. In the case of red meats, the oxygenation process causes the meat to turn a bright red color. The package includes a tray covered by a film with a plurality of apertures formed in the tray. The apertures are covered by a resealable gas impermiable tape which can be removed to allow air ingress and then resealed to protect the integrity of the tray contents.

  • Patent number: 5866181
    Abstract: A label assembly is provided allowing the aesthetic packaging of vegetables, other food items, or other products, for point of purchase display in a simple, versatile and effective manner. First and second flexible strips of material (e.g. paper or plastic) have a header formed at one end and are overlapped at the other end to be held together by adhesive. An adhesive pattern of discrete spaced adhesive elements is provided on the inner face of at least one of the strips and engages the container or covering of a product being packaged so that the label assembly does not inadvertently detach from the package. The label assembly is particularly suited for use with a microwavable tray having an open top covered by plastic shrink wrap and containing vegetables (there being no adhesive where the label covers the open top), or for encircling a number of low density polypropylene bags (e.g. containing vegetables) which are held together by the label assembly.

  • Patent number: 5356650
    Abstract: There is disclosed a process for producing solid honey wherein pure honey is subjected to dehydration in a vacuum evaporator with gradual temperature rise in a temperature range from ordinary temperature to 40.degree.-90.degree. C. within about one hour. The resultant concentrated pure honey is transported by pressure to a pouring part for supplying to a determined forming mold. In the meantime, heat-resistant plastic package containers which constitute determined forming molds are successively transported to the position of the pouring part, and the concentrated pure honey is charged to inside of the forming molds of the containers after a determined amount of edible fats and oils is previously applied. Spontaneous cooling then occurs followed by sealing up with a cover of an aluminium foil or a non-hygroscopic sheet at the side of opening part of the container. There is also disclosed a solid honey obtained by the process.

  • Patent number: 5348752
    Abstract: Dual state packaging may be implemented with a tray having a peripheral flange adapted to receive a pair of membranes to enclose the tray. The lower membrane is the more permeable of the two. It may be attached to a first surface of the flange. The second membrane is attached to a second outer surface of the flange without direct connection except through the tray to the more permeable membrane. The two connection surfaces may be separated by a depression to facilitate the cutting away of the material forming the more permeable membrane in a continuous manufacturing process. With the less permeable membrane in place, a desired gaseous environment may be maintained within the package. When it is desired to change the gaseous environment, the upper less permeable membrane may be peeled away allowing gaseous communication through the lower more permeable membrane.
