  • Patent number: 5863499
    Abstract: A self-venting package (A) contains peracetic acid or other strong oxidants in a unit dose that assures sterilization of instruments and equipment in an automated sterilizing apparatus (FIG. 3) or of biological wastes in a biological waste comminuting apparatus (FIG. 4). The self-venting package is constructed of a cylindrical body having first and second vent apertures (12, 14) 180.degree. offset adjacent a first edge (20) and third and fourth vent apertures (16, 18) 180.degree. offset adjacent a second edge (26). The first and second vent apertures are 90.degree. offset relative to the third and fourth vent apertures. The first edge is flattened and sealed forming a pair of corners (40, 42) such that the first and second vent apertures are disposed closely adjacent the first and second corners. The container is filled with peracetic acid or other liquids which liberate gas or vapors. A second end (26) of the container is flattened and sealed in a direction transverse to the first edge.

  • Patent number: 5662576
    Abstract: A method and apparatus for manufacturing an improved bag for the cultivation of mushroom spawn is provided. The bags have continuous gas permeable sealing strips sealed to the inside walls of the bags which cover openings in the bag, so as to allow the bag to be vented without loss of moisture. The openings and sealing strips are positioned close to the top and bottom of the bag so as to maximize air flow through the mushroom spawn without creating dry spots, thereby improving spawn yield. The apparatus includes rollers for dispensing plastic film and at least one continuous hydrophobic strip of material. A series of apertures are punched by cutting dies in the film, and a vacuum system removes the cut out portions. The strip of material is positioned over the apertures and sealed by sealing dies over them, so as to enclose the apertures. A cutting dies cuts off the film and strips. A conventional bag making machine then forms the bags.

  • Patent number: 4486187
    Abstract: A dispensing bag for particulate matter is closed at one end by a two layer closure formed by an openable outer closure, and an inner dispersion panel with apertures of suitable size therethrough. Opening the outer closure exposes the apertures in the dispersion panel and permits particulate matter to be dispensed therethrough. The bags may be conveniently mass produced from sheet material, such as flexible plastic, in the form of a continuous strip or flattened tube, by appropriate cutting, folding, and joining operations. The invention provides an inexpensive container from which particulate matter may be conveniently dispensed in controlled fashion, and which resists accidental opening and spillage.
