  • the collar body of the present invention may comprise a variety of materials, depending upon the ultimate use of the collar body. Desirably, the collar body and the resulting collar are self-supporting. Common materials used for making the collar body include chipboard (e.g., cellulose fiber based materials mixed with resin) and injection molded plastics (e.g., polypropylene, polystyrene, and polyethylene). In certain applications, where durability and heat resistance are desired, the collar body may be made of metal (e.g., copper, steel, or aluminum).
  • Such collar body may be manufactured in several ways.
  • the collar body may be die cut (e.g., using a rotary or plunge die), water jet cut, or laser cut from a continuous or discrete length of appropriate material such as chipboard, or plastic.
  • Plastic self-supporting collar bodies may alternatively be manufactured using injection molding techniques known in the art.
  • a fold line may be established using mechanical techniques (e.g., perforations, pre-scoring, kiss cutting, and molded living hinge) to weaken the collar body along a line that intersects the aperture. The fold line may intersect the aperture at any two points along the perimeter of the aperture.
  • a collar of the invention may be affixed to a dust collection bag (e.g., a vacuum cleaner bag) to form a dust collection assembly.
  • a dust collection bag e.g., a vacuum cleaner bag
  • Vacuum cleaner bags are known in the art and are conventionally constructed of paper. More recently, vacuum cleaner bags may be made of several layers and of various materials such as paper, polypropylene or other polymeric microf ⁇ ber webs, depending upon the desired particulate trapping efficiency. Exemplary vacuum cleaner constructions and materials thereof are described in U.S. Pat Nos. 5,647,881 (Zhang, et al); 6,156,086 (Zhang, et al); 6,251,154 (van Rossen); and 6,379,409 (Dijkman) and are incorporated by reference to the extent consistent with the present disclosure.
  • the collar is typically affixed to the filter bag such that the aperture of the collar body and the aperture of the filter bag is aligned to accept particulates from the dust collection system.
  • the collar may be affixed to the filter bag with adhesives, rivets, screws, nuts, and bolts or by other mechanical means such as sewing, ultrasonic welding or heat staking.
  • the affixation of the collar to the bag filter should be sufficient to perform under the prescribed conditions for the use of the dust collection system.
  • the apertures of the collar and filter bag assembly engage a dust collection fitting on the dust collection system.
  • the aperture is designed to fit the dust collection fitting and can assume a variety of shapes such as circular, square, rectangular, oval, or even an asymmetric shape.
  • the collar of the invention comprises a collar body having a mechanical fastener.
  • the mechanical fastener is a device that, upon folding the collar, inter-engages parts of the collar body.
  • the inter-engagement of collar body parts can be disengaged and inter- engaged one or more times without damage to the function of the engagement system.
  • a strip of adhesive may be applied to the surface of the collar body.
  • Useful adhesive materials known in the art include acrylic pressure sensitive adhesives and adhesives that may reversibly engage or are repositionable or irreversibly engage the dust collection assembly upon folding and contact with the adhesive strip. Peel-off membrane layers on the adhesive strip that are known in the art may be used to protect the adhesive strip until folding and sealing the dust bag is desired.
  • the dust collection assembly may be sealed by application of a gasket surrounding the collar aperture.
  • the gasket may comprise any compressible material (e.g., foam, natural rubber, styrenic block copolymers such as those available from Kraton Polymers, LLC, Houston, TX, under the trade designation “KRATON” and thermoplastic elastomers such as those available from Advanced Elastomer Systems, Akron, OH, under the trade designation "SANTOPRENE”) which upon folding of the collar creates a seal on the dust bag assembly.
  • compressible material e.g., foam, natural rubber, styrenic block copolymers such as those available from Kraton Polymers, LLC, Houston, TX, under the trade designation "KRATON” and thermoplastic elastomers such as those available from Advanced Elastomer Systems, Akron, OH, under the trade designation "SANTOPRENE
  • FIG. 2A shows another embodiment of a collar 200 that comprises a collar body 206 and a mechanical fastener in the form of a slit projection 202.
  • the slit projection 202 inter-engages the periphery 205 when the collar is folded along the fold line 201.
  • fold line 201 intersects an aperture 204 diagonally, thus allowing for the aperture 204 to be closed when the collar 200 is folded along the fold line 101.
  • FIG. 2B shows another embodiment of a dust collection bag assembly 210.
  • One face of the collar 200 is partially affixed to the dust collection bag 214.
  • the collar 200 is affixed to the dust collection bag 214 such that when the collar 200 is folded along the fold line 201, the aperture 204 is closed and the opening in the bag 208 is desirably sealed, thus minimizing or preventing the escape of dust and dirt from the dust collection bag 214.
  • the fold line 201 is positioned so as to intersect the aperture 204 and the opening in the bag 208 diagonally.
  • the portion of the face of the collar adjacent to the slit projection 202 is not affixed to the bag 214, thus allowing for the slit projection 202 on the collar 200 to freely engage the periphery 205 when folded along the fold line 201.
  • FIG. 2C shows the dust collection bag assembly 210 of Fig. 2B folded along the fold line 201. Furthermore, the slit projection 202 is engaged with the periphery 205 of the collar 200.

  • the slit projection 602 inter-engages the periphery 605 when the collar is folded along the diagonal pre-scored fold line 601.
  • the diagonal pre-scored fold line 601 intersects an aperture 604, thus allowing for the aperture 604 to be closed when the collar 600 is folded along the fold line 601.
  • an adhesive layer 609 is applied to the collar 600 to desirably seal the dust collection bag when the collar 600 is folded along the diagonal fold line.
  • FIG. 6B shows an embodiment of a dust collection bag assembly 610.
  • One face of the collar 600 is partially affixed to the dust collection bag 614.
  • the collar 600 is affixed to the dust collection bag 614 such that when the collar 600 is folded along the fold line 601, the aperture 604 is closed and the opening in the bag 608 is sealed, thus preventing the escape of dust and dirt from the dust collection bag 614.
