Definitions

  • the present invention is directed toward vacuum cleaner dust containers or bags that are manufactured from a tube-shaped filter material piece, which is flattened out and includes closures at both ends.
  • the closures extend substantially perpendicular to me longitudinal axis of the tube-shaped piece, and the tube-shaped piece also includes upper and lower filter areas that are joined to one another by folded portions at the two longitudinal side walls.
  • Such dust containers are well known and are used in almost all types of modem vacuum cleaners in order to separate dust particles from the air that flows into the vacuum cleaner. When the dust container is full it is easily removed from the vacuum cleaner and thrown away, resulting in a more hygienic disposal.
  • Dust containers of the aforementioned type are disclosed in DE-U1-29704079 , WO 95/16383 and JP 8-38406 .
  • the first reference shows a dust container having a longitudinal folded portion between the upper and lower filter areas.
  • the outer folding line of the longitudinal folded portion is shaped such that it coincides with the folding lines that divide the fold from the upper and lower filter areas.
  • US 3350859 A discloses a filter bag formed from a blank of filter material. The blank is cut into the desired length and the longitudinal side portions are folded. The thus obtained elongated sheet is then folded substantially in half along a folding line, which forms the bottom of the bag. Adjacent long sides of the folded blank extending upwardly from the fold line are glued together.
  • a vacuum cleaner dust container in accordance with the present invention, includes a bag having an opening through which dust laden air flows into the bag, and the bag includes a tube-shaped filter material piece that is flattened out and that is provided with closures at both ends. The closures extend substantially perpendicular to the longitudinal axis of the tube-shaped piece.
  • the bag also includes upper and lower filter areas, folded portions and two longitudinal side walls.
  • the upper and lower filter areas are joined to one another by folded portions at the two longitudinal side walls.
  • Each folded portion is connected to the upper and lower filter areas by first and second longitudinal folding lines, and includes three additional longitudinal folding lines forming four areas which, when the bag is flattened, at least partially overlap one another.
  • a third folding line connects the first and second areas
  • a fourth folding line connects the third and the fourth areas
  • the fifth folding line connects the second and fourth areas.
  • the fifth folding line is located outside relative to the first and second folding lines.
  • the dust container includes a dust bag 10 that is manufactured from one or more layers of a filtering, air permeable material.
  • the bag has a bag opening 11 surrounded by a plate 12 glued about the opening.
  • the plate 12 defines a plate opening 13 through which dust-laden air flows into the bag.
  • the plate opening 13 may be partially covered or surrounded by a rubber membrane or O-ring (not shown) that seals against an inlet tube of the vacuum cleaner. It is submitted that the structure of the plate, plate opening, and O-ring are well known and common in the art, and do not form part of the present invention.
  • the bag 10 is manufactured by shaping an endless or seamless web of filter material into a flattened tube-shaped substrate having an upper filter area 14 and a lower filter area 15. Upper and lower filter areas 14, 15 are joined to one another by two folded portions 16. The edge parts 17, 18 of the filter material are glued together. The tube-shaped piece is cut perpendicular to the longitudinal axis of the web to provide a bag of the desired length. The edge portions 19 that are formed in this manner are folded several times to form overlapping joints that are glued to the upper and/or lower filter areas 14, 15--and, optionally, to the folded portions 16 adjacent the bag ends in order to form sealed closures at the two ends of the bag.
  • the folded portions 16 constitute longitudinal sidewalls of the bag and include a first folding line 20 and a second folding line 21 that join the folded portions 16 to the upper and lower filter areas 14, 15, respectively. Between the first and second folding lines 20, 21, the folded portions 16 provide three additional folding lines 22, 25, 28 that form or separate four areas 23, 24, 26, 27, as will be apparent from the following description.
  • a third folding line 22 of the folded portion 16 is disposed between and connects a first area 23 and a second area 24.
  • a fourth folding line 25 of the folded portion 16 is disposed between and connects a third folding line 22 of the folded portion 16
  • the folded portion 16 is configured such that the fifth folding line 28 is outside of first and second folding lines 20, 21, while the third and fourth folding lines 22, 25 are inside of the first and second folding lines 20, 21, as illustrated.
  • the fifth folding line 28 is at least 5 mm outside the first and second folding lines, 20, 21.
  • the folding of the bag is such that the fifth folding line 28, when the bag is flattened out, is substantially straight and extends all the way between the two ends of the bag. This results in simplicity with regard to the closure process and an increased active filter area compared to the traditional arrangements.
