摘要:
A vacuum fill system for deaerating flowable materials includes a hollow container connected to a plurality of valves, slide gate valves and a vacuum pump for creating a vacuum when filled with flowable materials that causes the flowable materials to deaerate and subsequently compact when atmospheric pressure is restored.

The intrusion of insects into a home or similar building is controlled by utilizing insect controlling plastic materials in the construction of the building. The insect controlling plastic building materials are manufactured by first blending one or more plastic resins with one or more insect controlling chemical agents to form a blended plastic resin/insect controlling chemical agent material. The blended plastic resin/insect controlling chemical agent material is then utilized to manufacture plastic films, sheets, non-woven fabrics, woven fabrics, insulating foams, flooring materials, wall covering materials, and the like utilizing conventional manufacturing techniques.

A process of manufacturing a bulk bag begins with a tubular blank of woven polypropylene material which is cut along a first transversely extending line 64 to form the upper edges of lift sleeve portions 76, cut along longitudinally extending lines 66 to form the side edges of the lift sleeve portions 76, and cut along substantially transversely extending lines 68 situated at the midpoint of the lines 66 to form opposed top wall halves 72 and opposed bottom wall halves 74. The top wall halves and the bottom wall halves are then sewn together along sew lines 82 and 84, respectively. Sidewalls 70' are joined to the bottom wall halves 74 along sew lines 86, and the top wall halves 72 are joined to the sidewalls 70' along sew lines 88. The lift sleeve portions 76 may be configured to provide lift sleeve, lift rope, or single point lift construction. The top and bottom walls may be provided with a fill chute and discharge chute, respectively.
摘要:
A process for the construction of a bulk container including a glued bottom portion. A blank is suspended in the shape of the desired container and is positioned over a bottom portion. Adhesive or glue is applied to the bottom portion in areas which will contact the blank. The blank is lowered into contact with the blank and fins are formed. The fins are either folded, cut and/or secured to complete the container in one of several ways.

A bottom lift bulk bag (10) comprises one or more sidewalls (12) defining the interior (14) of the bulk bag. The lower end of the bulk bag is closed by a bottom wall (22) which is secured to the lower ends of the sidewall panels. The material of the bottom wall is extended in the form of a pair of opposed lift loops (26) which are secured in place by seams (28) interconnecting the lower ends of the sidewalls and the bottom wall. In the use of the bulk bag, rigid lifting members (66) are extended through the lift loops and are used to lift the bulk bag from the bottom.
摘要:
A material holding receptacle constructed of pliable material and having a main enclosure and a hopper below the enclosure. The hopper consists of a trapezoidal bottom piece and three triangular bottom pieces. The bottom pieces can be folded upward to form a substantially flat bottom to the receptacle. A cover piece is attached to the trapezoidal bottom piece to form a receptacle access tube over an opening in the trapezoidal bottom piece. A loop is attached to the bottom corner of one of the bottom pieces to secure the bottom pieces.

A collapsible receptacle (570) has a bottom wall (574) provided with a discharge spout (582). The discharge spout (582) is provided with an interior layer (586) which is grounded during the flow of material through the discharge spout to prevent the buildup of static electric charge therein. The bottom wall (574) may also be provided with an electrically conductive layer (592) to further prevent the buildup of static electric charge in materials flowing out of the collapsible receptacle (570) through the discharge spout (582). The conductive layers (586, 592) may be electrically interconnected.

The intrusion of insects into a home or similar building is controlled by utilizing insect and/or microorganism controlling plastic materials in the construction of the building. The insect and/or microorganism controlling plastic building materials are manufactured by first blending one or more plastic resins with one or more insect and/or microorganism controlling chemical agents to form a blended plastic resin/insect and/or microorganism controlling chemical agent material. The blended plastic resin/insect and/or microorganism controlling chemical agent material is then utilized to manufacture plastic films, sheets, nonwoven fabrics, woven fabrics, insulating foams, flooring materials, wall covering materials, and the like utilizing conventional manufacturing techniques.
摘要:
A bulk bag for dense materials includes side walls seamed together end-to-end to form a rectangular enclosure and at least a bottom wall secured to the lower ends of the side walls. Baffles are secured in the side wall seams and extend diagonally across the interior of the bulk bag to maintain the bulk bag in a rectangular cross-sectional configuration when filled with dense materials.
摘要:
A method of manufacturing a shoe lining having anti-microbial properties. The method comprises providing a quantity of a thermoplastic resin including an inorganic zinc-based anti-microbial agent admixture having a predetermined microbial inhibition characteristic. This thermoplastic resin is blended with a polyethylene resin to form an anti-microbial feedstock. The anti-microbial feedstock is formed into relatively long, narrow, thin lengths of anti-microbial members. These members are woven into an anti-microbial fabric having predetermined microbial inhibition characteristics. This fabric is cut into a plurality of pieces in accordance with a predetermined pattern and the pieces are joined together thereby constructing the anti-microbial shoe lining.
