3 members 36 and 31 define a dirt filtering cavity or pocket 43. The lower end of the wall-member 31 and the trap 38 define a dirt collecting pocket or cavity 44. In other words, the cardboard trap 38 divides the lower end of the bag into two compartments, namely 42 and 44.
Figs. 3 and 6 show the three principal members of the disposable bag l1, and indicate that the pervious wall-member 36 is a single piece of fiat material extending the full length and the full width of the disposable bag l1. Figs. 3 and 6 also show that the pervious wall-member 31 is formed from a single piece of pervious material longitudinally infolded at 46-46 and outfolded at 41-41', to form accordion folds. The folds 46 and 41, 46' and 41' cause the wall-member 31 to have a panel 48, two inwardly hinged leafpanels 49 and 49', as well as two outwardly hinged leaf-panels and 5|. The wall-member 31, when completely folded, is coextensive with the wall-member 36 and positioned in such a manner that the free longitudinal external edges of the leaf panels 5| and 5| are joined by straight parallel lines of stitches 52 and 52 to opposite edges of the longitudinal wall-member 36. Fig. 3 also shows that the trap member 38 is coextensive with only the lower or inlet half of wall-member 36, the trap member 38 being located between the wall- members 36 and 31 and secured in place by the same straight lines of stitches 52-52' that hold the two members 36 and 31 together. The upper end 39 of the disposable bag is closed by a straight line of stitches 54 extending perpendicular to the lines of stitches 52 and 52', and all the lines of stitches 52, 52' and 54 may be formed by a conventional fiat-bed sewing machine. The open or inlet end 4| of the bag |1 preferably is stitched on a cylinderbed sewing machine, thereb forming what will be termed, for the purpose of the present description, a straight line of stitches 56 that extends circumferentially around the open mouth 4| of the bag l1, it being understood that the line of stitches 56 forms two parallel straight lines of stitches when the bag is folded for ship ment, and a circular line of stitches when the mouth 4| of the bag is opened for insertion of the aluminum tube 21. The stitching 56, which is perpendicular to the lines of stitches 52 and 52, not onl prevents the ends of the bag from fraying, but also closes the lower end of the dirt collecting cavity 44. Fig. 5 shows a detail of the stitching 56 as it extends around a portion of the open bag mouth 4|. The stitching 56, at a location indicated by the numeral 51, secures the trap 38 to the bottom panel 48, and at another location, indicated by the numeral 58, secures together four layers, comprising, the bottom panel 48, the leaf-panel 49, the leaf-panel 5| and the trap 38. The line of stitches 56, at another location, indicated by the numeral 56, simply acts as a binding as it passes through the single layer of the wall 36. Fig. 4 shows the inner and outer bags in an inflated condition. When so inflated, the folds 46, 46, 41 and 41 of the inner disposable bag l1, become ordinary ribs as shown.
In use, the inner disposable bag H is placed within the outer bag l6 and attached to the aluminum tube 21 in the following manner. Assuming that the connector- 24 is attached to the exhaust outlet (not shown) of a vacuum cleaner, and assuming that the bail 22 is supported in an upright position by the handle (not shown) pf a vacuum. cleanenthe slide-fastener I9 is opened to expose the inner bag l1 and the trunk latch 33, which latter item is opened. This permits the two-part clamping bands 3|32 to swing backwardly and allows removal of the old bag. After the open mouth of the replacement bag I1 is slipped over the upper end of the aluminum tube 21, the edges of the bag mouth are folded as at 6|-6|' and the two-part clamping bands 3|-32 are clamped around the folded mouth 4| and tube 21 by the trunk latch 33. Thereafter, the slide-fastener I9 is closed and the vacuum cleaner is ready for use.
Dust and dirt, exhausted from the vacuum cleaner, enters the plastic tube 26, passes through the aluminum tube 21 and into th passageway 42, from whence it passes into the dirt filtering cavity 43. The dirt and dust is retained in the disposable bag I1, while the filtered air passes through the pervious wall 36 and the panels 48, 4949 and 5|'--5|'. Since the outer and inner bags are supported in a vertical position by the vacuum cleaner handle, the dirt and dust settles from the cavit 43 into the collecting pocket 44. This assures that the upper portions of the walls 36 and 31 will be kept relatively clear, thus maintaining their ability to act as filters.
During construction of the bag I1, the cardboard trap 36 is fiat and fairly rigid. This keeps the bag in the desired form and facilitates handling the bag during the sewing operations. When the mouth 4| of the bag I1 is slipped over the aluminum tube 21, the trap 38 bends widthwise thus providing a rigid channel or passageway 42 which dresses the lower end of the bag. Since the trap member 38 extends only one-half the length of the bag, the upper end 62 of the trap 38 provides a convenient plac on which to fold the pervious members 36 and 31. When the disposable bag I1 is folded on the line 62, it is easily packaged and shipped.
When the disposable bag 11 is placed in the outer bag I6 in the usual manner, the wall 36 forms the upper side, and the wall 31 forms the lower side of the bag and, when the thus positioned bag is used, dirt falls by gravity into the pocket 44. However, it will be understood that the disposable bag |1 may be placed in the outer bag IS with the wall 31 uppermost, and the wall 36 lowermost. Under these conditions the dirt is blown into the pocket 44 by moving air currents within the bag.
Figs. 7, 8 and 9 disclose an inner disposable bag |1a that is similar to the bag |1 shown in Figs. 1 through 6. The numerals used to designate parts of the bag Na in Figs. 7, 8 and 9 are the same as those used on similar parts in Figs. 1 through 6, except that subscripts a and. b have been added to the numerals of Figs. 7, 8 and 9. The bag I101. differs from the bag H in that the mouth 41a of the bag |1a is stitched, preferably by a flat bed sewing machine, with two separate straight lines of stitches 56a and 56b that are perpendicular to lines of stitches 52a and 52'a, instead of being stitched with a circumferential line of stitches 56 by a cylinder bed machine. The stitching 56a only passes through the single layer pervious wall member 36a and thus simply acts to prevent the end of the wall 36a from fraying. The stitching 56b passes through the cardboard trap member 38a, through the bottom panel 48a, as well as through the leaf- panels 49a and 5|a. Thus the stitching 56b, not only prevents the ends of the panels 48a, 49a, 5|a, etc.
from fraying, but also closes the lower end of the dirt collecting cavity 44a. Fig. 8 shows a detail of the stitchings 56a and 56b. As indicated above, the stitching 56a simply passes through the pervious wall 36a. The stitching 561), at a location indicated by the numeral 51b secures the trap 38a. to the bottom panel 48a, and at another location, indicated by the numeral secures together four layers comprising, the bottom panel 48a, the panel 49a, the panel 5m and the trap 38a. At locations 80a and 60a (Figs. '7 and 9), where the side edges of the wall-member 38a are folded back, the stitching 58b secures the wall 36a to the trap 38a, to the panel Mia and to the inwardly and outwardly hinged leaf-panels designated in Fig. 8 as 49a and 5m.
In sewing the disposable bag shown in Figs. 7, 8 and 9, the line of stitches 56a preferably will be formed first. Thereafter, the two longitudinally extending lines of stitches 52a and 82% will be formed. Then, either the line of stitches 54a or the line of stitches 56b may be formed, depending on the convenience of the sewing machine operator. In applying the line of stitches 551) (Fig. 9), it will be necessary for the operator to lift the intake end of the wall member 36a, this in order to expose the upper surface of the cardboard trap 38a. The disposable bag lid, in its uninfiated condition, lies fiat, all the members 36a, 38a, 48a, 49a, 5la etc. being parallel to a common plane.
The disposable bag Ila is used in exactly the same manner as that previously set forth in connection with the description of the bag 11.
In the bags shown, the traps 38 and 380. have been indicated as made of relatively stiff impervious material. By sacrificing some of the advantages hereinbefore discussed, the trap members 38 and 38a. may, for certain applications, be formed from pervious and/or non-rigid material.
