Appl. No.:

09/732471

Inventors:

Ronald D. Robertson - Kansas City MO

Assignee:

Sealright Co., Inc. - Desoto KS

International Classification:

B31B 144

US Classification:

493167, 493156, 229 55, 220620

Abstract:

A method and apparatus for constructing a dispensing end portion of a cartridge used to hold and dispense food sauce. A flat end disk is held in a transfer pocket and moved by a disk punch through a die opening smaller in diameter than the disk. The die bends the peripheral portion of the disk into a skirt. The disk punch inserts the disk into the open end of a cartridge body and against a mandrel positioned so that an end portion of the cartridge body extends beyond the skirt. Heat is applied to melt thermoplastic coatings on the disk and cartridge body. A crimping device crimps the end portion oft he cartridge into a flange which is bent against the disk and folds the skirt to form a lip doubled over on the peripheral area of the disk. Thermoplastic coatings bond to weld the flange to the disk with the lip enclosed between them.

US Classification:

294265, 294264, 156247, 156344

Abstract:

A method and apparatus for lifting the tabs of a protective seal with edges embedded in a laminate. The base of the device has an annular top having a plurality of cartridge receiving apertures spaced equally from one another. Each hole receives a tab engagement assembly comprising a cartridge, a spring, and a finger have an abutment surface. The finger is pivotally fastened at one end within the slot of the cartridge and is biased away from the cartridge by the spring. When the base is placed in proximate relationship with the laminate seal patch secured to the substrate, the rotating base causes the abutment surfaces of the fingers to drag across the periphery of the laminate seal in a circular motion. The stresses created on the tabs of the protective seal cause the embedded edges to be lifted. The lifted tabs are accessible to the end user and the protective seals may be easily peeled from the substrate when desired by the end user.

US Classification:

493 52, 493 59, 493 69, 493 79, 220276

Abstract:

A tamper evident and resistant container lid of the present invention includes a lid body configured to cover the opening of a base container having a top rim and a skirt extending from the lid. The skirt has an annular score line and an annular fold line extending therearound. An outer band of the skirt extends between the score line and the fold line, and an inner band folded inwardly to be in opposing relation to the outer band extends upwardly from the fold line to an upper free edge. When the container lid is sufficiently applied to the base container such that the second portion slides downwardly past a top rim of the base container, achieving a proper closure, an attempt to remove the lid will cause a plurality of sections of the inner band to engage the top rim and impede removal of the container lid from the base container.

Abstract:

A storage container includes a receptacle having a circumferential sidewall and a sleeve fixedly attached to the receptacle having a circumferential sidewall with a left edge, a right edge, and marginal portions adjacent the left and right edges wherein the edges meet to form a butt seam. The receptacle sidewall and the sleeve sidewall define an insulating layer therebetween. The insulating layer includes a first edge and a second edge wherein the first and second edges do not extend under the marginal portions such that the insulating layer has a smaller circumference than that of the sleeve sidewall. A method for forming a storage container is also provided.
