Patent number: 5702001Abstract: A container having panels that contain a bag of strip material. The container is movable between a confining position enclosing the bag of strip material and a position in which the bag is relaxed so as to relax snags of looped elastic material that may have arisen during transit. During transit, the strip material has a tendency to flow from the top and over the edges of the bulk to work its way along the sides, potentially snagging with adjacent loop material. During dispensement of the strip material, these snags may give rise to tension spikes. By displacing the panels of the container out of the confining position and into a relaxed position, the confining forces become relieved and thereby the snags relax. The tension spikes otherwise arising during dispensement are thereby eliminated.Type: GrantFiled: August 17, 1994Date of Patent: December 30, 1997Assignee: The Moore CompanyInventors: William E.

A first end of the tube is then sealed closed. Air is then evacuated from the tube through the second end thereby deforming the tube around the article and causing the article to compress. While a vacuum is maintained in the tube, the second end of the tube is sealed closed. A containment sleeve is fitted over the sealed tube to maintain the article in a compressed state. When the article is unpackaged, the containment sleeve is severed and the tube is allowed to expand in a gradual controlled fashion by the bleeding of air back into the tube.Type: GrantFiled: August 9, 1996Date of Patent: April 22, 1997Assignee: Simmons CompanyInventors: C.

Patent number: 5544578Abstract: A device for compressing tires and other compressible items in a shipping container comprises a support frame 22 attached to the lift end of a forklift. A fixture 20 is attached to and moves vertically with the support frame. The fixture comprises a horizontal compression platen 30. A vertical pusher plate 50 extends above and below the platen. The upper pusher plate 53, which is above the platen, can fold down so that the platen can be brought near the ceiling of a shipping container above a stack of tires. The fixture weighs enough to compress tires stacked below the compression platen. Additional tires are stacked above the platen and compressed tires. The upper pusher plate is then folded up, against the tires. Two hydraulic cylinders push the pusher plate away from the support frame to pull the platen from between the tires.Type: GrantFiled: September 1, 1994Date of Patent: August 13, 1996Inventors: Michael Keller, Gerald Wheeler

Patent number: 5542234Abstract: The present invention is directed to an improved combination comprising a resealable container with a matching lockable lid and methods of formation "in-line" and use thereof. The container includes a rounded container lip near the top extremity of the container. The matching lid includes a substantially rounded lid lip which is slightly larger than and of substantially the same shape as the lip for the container. The transverse cross-sectional shape of the lid lip is that of a substantially smooth curve, and the transverse cross-sectional shape of the container lip for receiving, engaging and compressing the smooth curve of the lid lip is substantially V-shaped in order to exert force upon the smooth curve of the lid lip after mating engagement for effectuating a seal therebetween. The novel features of the container and lid hereof are such that they may be formed separately on separate machines or may in other embodiments be formed and used "in-line".Type: GrantFiled: April 21, 1994Date of Patent: August 6, 1996Assignee: Sara Lee CorporationInventors: Ihor Wyslotsky, Frank C.

Patent number: 5507130Abstract: A tissue package comprising a plurality of tissues and a dispensing package. The plurality of tissues is compressed in two discrete stages, each of which stage can be released independently from the other. The first stage of compression is less than the second stage of compression. The tissues are transported and stored while under the second stage of compression. The user releases the second stage of compression, whereby the tissues can expand up to the first stage of compression. The user releases the first stage of compression just before installing the plurality of tissues into a dispensing package or dispenses the tissues through a restraint while they are held in the first stage compression.Type: GrantFiled: June 2, 1995Date of Patent: April 16, 1996Assignee: The Procter & Gamble CompanyInventors: Mark D.
