  • VACUUl-CLEANER BAG l Filed ual-n 11, 195s 2 Sheets-Sheet 2 TjT/a lPatented Apr. 8, 1941 UNITED VACUUM-CLEANER BAG Ragnar K. sterdahl, Essingen, Sweden Application Maren 11, 193s, serial' No. 195,370
  • This invention relates to vacuum cleaners and morepartlcularly to bags adapted to be attached to the same to receive more or less coarse sweepings and, preferably, also the dust collected by the cleaner, and it is an vobject of my invention to provide a replaceable and destructlble bag for such purpose, which may be made very cheaply, supplied to the consumer at a very low price and can be shipped and stored in a completely flattened shape, even though it has in use an outwardly extending annular flange for its safe fastening to the cleaner.
  • 4Another object of my invention is to provide a vacuum-cleaner bag that can be secured to the vacuum cleaner by means of an outwardly extending ange which can easily be collapsed, so as to avoid the escape of dust and dirt from the bag, when the latter is removed from the container.
  • Fig. 1 is a longitudinal view, partly in section, of the main parts of a vacuum cleaner illustrating the improved bag in place.
  • Fig. 2 is a side view of the flat bag.
  • Fig. 3 is an end View of the opened bag ready for insertion into the cleaner.
  • Figs. 4-7 illustrate some steps of manufacturing the bag.
  • Fig. 8 illustrates a part of the bag.
  • Fig. 9 illustrates, partly in section, a modified embodiment of the improved flat bag.
  • Fig. 10 illustrates a modified part of the bag shown in Fig. 9.
  • Fig. 11 illustrates .another modified part of the bag shown in Fig. 9.
  • Fig. 12 is a sectional View showing a modifled embodiment of the mouth of the bag shown ln
  • Fig. '1 shows the air-pervious bag I in place within the casing 2 of the vacuum cleaner which encloses l the motor driven fan 45.
  • the inserted bag has an annular, radially extending iiange 3 which is clamped between a ring 40 and acover 4.
  • the bag I is' placed within a bag 42 of cotton which has a metal flange 4I that is clamped between the ring 40 and an annular flange 5 of the casing 2.
  • the opening 6 in the cover 4 is connected with the suction nozzle (not shown) of the cleaner, and the opening 1 of the casing is the outlet for air passing .through the fan 45.
  • the bag is composed of a mouth portion 8 and a perforated body portion 9 which has aps I0 cut out in its wall.
  • a band I6 of paper or another suitable sheet material is provided with transverse creases II and I2, a longitudinal crease I3 and creases I4 extending diagonally between the creasesV II and I2, as shown in Fig. 4. These creases have the effect of pleating the mouth portion of the bag. Thereafter, the band I6 is folded transversely along the creases II and I2, as shown in Figs.
  • One or a plurality of the vacnum-cleaner bags can be enclosed in their flattened state in a hat envelope, since the portion of the bag that is adapted to form an annular attaching flange forms a direct extension of the bag when the latter is collapsed. Thus they can easily be packed, stored, shipped and distributed and even though, when in use, they are intended to form a substantially cylindrical collector having an outwardly extending annular flange for a particularly safe attachment.
  • the folded mouth 8 is bent outwards to form a substantially annular flange 3 (Fig. 3) which obtalns a regular polygonal shape as the creases I4 facilitate a regular unfolding of the folds I1.
  • this bag has substantially for its object to collect fibrous matter, so that the cleaner can be in use for a very long time before it will be necessary to release and clean the ordinary fabric bag.
  • the perforated paper bag will form an air-pervious layer that porous filler 23 consisting of fibrous lignocellulose enclosed within the wall 9 and an inner openwork wall or lining 24 which affords large openings 26.
  • porous filler 23 consisting of fibrous lignocellulose enclosed within the wall 9 and an inner openwork wall or lining 24 which affords large openings 26.
  • a filler of fibrous lignocellulose is particularly well adapted for the purpose as it will not be unduly felted when the bag is in use or stored.
  • the filler 23 is first glued to a web of open-work lining leavingmargins 26 and 2l extending beyond the filler.
  • a web of paper having cut out flaps I0 covering its perforatlons is glued at some points to the filler.
  • 'I'he folded bandv 8 is made substantially in the manner heretofore described but it is provided by way of example that a fiat band 28 is doubled on and glued to both sides of a margin of the folded band 8.
  • the band 28 is glued to the margin 26 and to the adjacent edge of the wall 9, so that an air tight joint is obtained.
  • the margin 21 of the lining 24 is,tightly attached to the wall 9 by means of a strip 29 which is glued to the inner side of the wall 9 and to the margin 21.
  • the blank thus formed with the mouth portion is cut, folded and 'sealed in the same manner as mentioned above to constitute substantially a Satchel bag of paper or similar suitable combustible material.
  • the manufacture of the bag can be carried out completely automatically on forming a continuous band composed of the outer wall, ⁇ a filler, a lining and a folded band which is fed through the machine.
  • a corrugated, air-pervious filler 3l,as shown in Fig. 10 may be substituted for the fibrous filler 23.
  • the filler might be covered with a fibrous coating 46 of lignocellulose or another suitable material. Said coating serves to trap coarser impurities whilst the filler 9 serves to trap dust ⁇ or the like.
  • the band 8 is glued to the inner side of the wall il.
  • a strip 44 of paper or another suitable sheet material is glued to the margin 26 of the lining as well as to the band 8, so that an air tight joint is obtained.
  • Such an attachment might be arranged also in the embodiment shown in Figs. 2 and 3.
  • 'Ihe filler may be saturated 75 with one or more suitable matters adapted to adhere dust, absorb moisture of the air as well to refresh the air passing through the cleaner.'
  • the bag with its mouth portion can be fiattened completely it can be enclosed hermetically within an envelope, the additional matters will not evaporate or be destroyed when the bags are stored.
  • the bag inserted into the vacuum cleaner assumes when in use a substantially cylindrical shape conforming to the annular shape of its mouth, but it is likely to resume its original fiat shape when the suction effect is changed.
  • the porous or fibrous finer or coating has a selfcleaning tendency due to pulsatory movements of the bag Walls.
  • a vacuum-cleaner bag having a collapsible body portion and a collapsible mouth portion having substantially the same width as said body por-tion and forming a longitudinal extension thereof, said collapsible mouth portion consisting of a strip attached at one edge to said body portion and having collapsible pleats extending in the longitudinal direction of said body portion. said pleats being stuck together at said edge, said mouth portion being adapted to be bent outwards on unfolding said pleats to form a radially extending substantially annular fiange extending laterally beyond said body portion for attachment to the vacuum cleaner.
