Definitions

  • This invention relates to receptacles and is particularly concerned with dust receptacles and the mounting and attaching means therefor together with the structural features of the cleaner which cooperate with the dust receptacle.
  • Another object of the invention is to provide a self-closing and self-securing receptacle which is when in use of substantially uniform cross-section throughout its length.
  • Another object is to provide a self-sealing and I self-retaining dust receptacle which includes a substantially rigid end member for supporting the receptacle in a position for maximum volume and for providing ample support for the flexible sealing portions of mouth.
  • an object of the invention is to provide a new and improved sealing and securing mouth for a self-closing receptacle.
  • Fig. 1 is a transverse Vertical section of one embodiment of the present invention
  • Fig. 2 is a detailed front view of the bag shown in Fig. 1 with the mouth in closed position;
  • Fig. 3 is a detailed view similar to Fig. 1 showing the bag mouth in applied position.
  • numeral In indicates a vacuum cleaner casing housing, having a conventional motor-fan unit II and dust separating means including a paper dust bag I3 of the present invention located within a cloth bag I2.
  • the motor-fan unit produces flow of air from left to right through the casing ID as shown in Fig. 1, drawing air through a flexiblehose I4 connected in the inlet opening of the front cover I5.
  • a flexiblehose I4 connected in the inlet opening of the front cover I5.
  • the cloth bag I2 is secured to the housing III by engagement with a gasket I! mounted between the housing In and the front cover I5.
  • the paper receptacle I3 is secured on the front cover I5 independently of the housing II] by engagement with a circular inlet tube I8 associated with the suction opening.
  • the bag I3 which is preferably formed of porous paper or like inexpensive material, is preferably of substantially rectangular cross-section throughout, thus lending itself to economy of manufacture and providing maximum volume permitting simple folding operations, and providing minimum space for storage.
  • the mouth of the present bag is also substantially rectangular and is closed by the insertion of the ends I9 of the side walls between inner and outer apertured end walls 20 and 2
  • the end walls 20 and 2I are suitably secured together with the wall section of the bag I9 therebetween as by staples 22 indicated in Fig. 2.
  • the end walls 20 and 2I are preferably formed of a normally rigid and inexpensive material such as, for instance, cardboard and each is perforated to form a through aperture 23 which is adapted to receive with a relatively snug fit the inlet tube I8.
  • the aperture 23 'of the bag mouth is normally closed by a pair of thin rubber overlapping sheets 24 and 25 which are secured between the ends 20 and 2
  • the sheet 24, however, is wider than the sheet 25 and extends downwardly beyond the center of the aperture 23 to provide an edge 21 which normally lies in overlapping relation to the upper edge of the lower sheet 25, thus normally closing the aperture of the bag mouth.
  • the sheets 24 and 25 are preferably formed of a very thin and flexible rubber, such as a latex preparation, the arrangement being such that upon application of the bag end to the aperture 23, the end of the end of the tube will stretch the rubber, forcing the overlapping edges to separate and to receive therebetween the end of the tube I8 as shown in Fig. 3.
  • the edges of the sheets thereupon seal the bag mouth to the tube I8 and also act as a resilient means for securing the bag to the tube so that upon the removal of the cover I5, the bag will be retained with the tube I8 and be withdrawn from the cleaner.
  • aperture 23 of the end member as shown in Fig. 3 is shown as of exaggerated dimension with respect to the dimension of the tube I8, it will be understood that its dimension may very closely approach the external dimension of the tube 18, in which case a frictional securement of the bag mouth to the tube 18 is provided by engagement of the edges of the aperture 23 with the tube in which case the function of the sheets 24 and 25 may be solely as a self-closing device for the bag and their virtue as sealing and securing members is of diminished importance.
  • a disposable dust bag for separating and collecting dust from the air stream of a suction cleaner having an inlet tube, said bag having a body of relatively porous flexible material and having a relatively stiff end portion provided with an aperture for the reception of the inlet tube of the cleaner, said aperture being of a size substantially less than the size of the end of the bag and substantially conforming in size to that of the exterior of the inlet tube which it is adapted to receive, means for providing a relatively tight joint between such inlet tube and the end of the bag about the aperture when the inlet tube is inserted in said aperture and to obstruct the aperture when the inlet tube is removed, said means comprising elastic sheet material disposed across said aperture and providing a substantially self-closing opening adapted to accommodate and be displaced by said inlet tube when it is inserted into said aperture to provide communication through the tube with the interior of the bag, said sheet material being adapted to return to its normal position across said aperture upon removal of the inlet tube from the aperture.
  • a disposable dust bag for separating and collecting dust from the air stream of a suction cleaner having an inlet tube, said bag having a body of relatively porous flexible material and having a relatively stifi end portion provided with inserted in said aperture and to obstruct the the aperture is covered by said sheets, said sheets being displaceable by said inlet tube when it is inserted into said aperture to provide communi-- cation through the tube with the interior of the bag, said sheets being adapted to return to their normal position across said aperture upon removal of the inlet tube from the aperture.
  • a disposable dust bag for separating and collecting dust from the air stream of a suction cleaner having an inlet tube, said bag having a body of relatively porous flexible material and having a relatively stiff end portion comprising a pair of sheet members secured together and provided with an aperture for the reception of the inlet tube of the cleaner, said aperture being of a size substantially less than the size of the end of the bag and substantially conforming in size to that of the exterior of the inlet tube which it is adapted to receive, means for providing a relatively tight joint between such inlet tube and the end of the bag about the aperture when the inlet tube is inserted in said aperture and to obstruct the aperture when the inlet tube is removed, said means comprising elastic sheet material disposed between said sheet members and extending across said aperture and providing a substantially selfclosing opening adapted to accommodate and be displaced by said inlet tube when it is inserted into said aperture to provide communication through the tube with the interior of the bag, said sheet material being adapted to return to its normal position across said aperture upon removal of the tube from the aperture.
  • a disposable dust bag for separating and collecting dust from the air stream of a suction cleaner having an inlet tube, said bag having a body of relatively porous flexibl material and having a relatively stiff end portion provided with an aperture for the reception of the inlet tube of the cleaner, said aperture being of a size substantially less than the size of th end of the bag and substantially conformin in size to that of the exterior of the inlet tube which it is adapted to receive, means for providing a relatively tight joint between such inlet tube and the end of the bag about the aperture when the inlet tube is inserted in said aperture and to obstruct the aperture when the inlet tube is removed, said means including a movable member of elastic material attached to said end and partially covering said aperture and another movable member attached to said end and covering that portion of said aperture left uncovered by said first member, said members being movable to admit said inlet tube upon insertion thereof through said aperture to provide communication through the tube with the interior of the bag, said members being movable upon withdrawal of said tube to close said aperture.
  • a disposable dust bag for separating and collecting dust from the air stream of a suction cleaner havin an inlet tube, said bag having a body of relatively porous, pliable material ineluding a relatively stiff end portion having an aperture for the reception of the inlet tub of the cleaner, means for preventing exit of material through said aperture after the bag is removed from the cleaner comprising a displaceable member of resilient material overlying said aperture when in closed position, a second displaceable member co-operating with said first member to close said aperture and prevent exit of material therethrough, said members being displaceable upon engagement therewith by said inlet tube to permit insertion of said tube into said bag and being adapted to return to said closed position upon withdrawal of said tube.
