' y 1957 R. T. PEEK DISPOSABLE DUST BAG Filed July '7, 195:5
RoeLqf meadows P ee1 JTTOR NEI DISPOSABIJE DUST BAG RoelofTheodbrus Peek, Amsterdam, Netherlands Application July 7, 1953, Serial No. 366,517
Claims priority, application Netherlands March 9, 1953 2 Claims. (Cl. 183-69) This invention relates to a dust-catcher to be used in vacuum cleaners and particularly to a disposable bag for use as a liner in vacuum cleaners.
United States Pat fo Emptying dustbags of vacuum cleaners usually is a 7 most unhygienic and troublesome job which produces large clouds of dust and everything close to a dustbin becomes covered with a layer of dust. To have a vacuum cleaner to draw well, it is often necessary that the dustbag of a vacuum cleaner should receive an extra cleaning, for instance, by beating it or brushing it OK. This cannot be done, however, without causing the area where one is cleaning the dustbag to be shrouded in clouds of dust.
There is no need to demonstrate that these actions are highly unhygienic because of the inhaling of dust. Efiorts have been made to manufacture dustbags of paper or other suitable material, which after the lapse of some time could be thrown away. Dustbags of such form, however, are too expensive for general use and too complicated; moreover, they fit vacuum cleaners rather badly.
It is accordingly a basic object of the invention to supply a dustbag which fits in the fixed dustbag of a vacuum cleaner as a loose part, which when filled with dust, can be thrown away.
Another object of the invention is to supply a disposable dustbag .as a loose part which can be used in practically all known makes of vacuum cleaners.
Other objects and advantages of the invention will in part be obvious and in part appear hereinafter.
The invention is embodied in a disposable dustbag for vacuum cleaners characterized by its being formed of a plurality of layers of very porous paper stitched loosely into the form of a bag, having a rounded'end, the creping being oriented so as to run longitudinally, the whole being enclosed in a very loose net, so that upon insertion into a tank or bag of a vacuum cleaner the air current will cause the bag to expand and fill the cleaner to function as a filter.
According to the invention the dust-catcher is secured by means of the net bag containing one or more layers of the porous crepe paper along the rim of the opening of the dustbag of the vacuum cleaner. A practical form is obtained, according to the invention, because the layers of porous material of crepe paper with the creping so oriented to the shape of the disposable bag that the bag is extensible radially. The insertion of this dust-catcher into a dustbag of a vacuum cleaner is made simple, because the net extends past the rim or opening of the bag formed by the layers of crepe material, and, accordingly, the open end of the dust-catcher can be easily pulled around the opening ring of the permanent dustbag of the vacuum cleaner.
A simple and inexpensive mode of manufacture is possible because the bag is formed by sewing the layers of crepe material together to form a laminate.
The invention will now be referred to a complete example illustrated in the drawings,
Figure 1 is a view in perspective of a dust-catcher made according to the invention;
2,800,194 Patented; J uly 23,-. 1957 2 Figure:2;is a longitudinal sectionthroughraportion of the bag to show thearrangement of .laminations making up its structure;
" Figure: 3." a. section ofadustbag: of: a vacuum. cleaner The dust-catcher according to the invention is a bag which is made up of layers of very porous tissue paper or lightly matted cellulose fibres, which bag is formed from two halves 1 and 2, fixed to one another in the shape of a bag, for example, by means of a stitch seam 3 which follows a longitudinal section line through the cylindrical bag as shown. Around the unit is attached a tube-shaped net 4, for instance, knitted of cotton or rayon. Near the rim opening 5 of the bag, the network is attached to the layers 1 and 2 by means of stitch seam 6 which passes circumferentially around the opening of the bag. The layers 1 and 2 are porous and may be formed ofrcrepe paper, which regarding the shape of the bag is oriented so that the bag is extensible radially.
The halves 1 and 2 may consist of a plurality of plies, such as the three separate plies shown in Figure 2 as 7, 8 and 9. Putting the dust-catcher into the dustbag of the vacuum cleaner may easily be accomplished by pulling the portion of the net 4 extending past the opening 5 around ring 10 of the dustbag of the vacuum cleaner, for example a tank type, in such a Way that the opening 5 is firmly held, when the dustbag 11 of the vacuum cleaner itself is fixed in place. This is illustrated in Figure 3. When the dust-catcher is full the projecting part of the net around ring 10 is removed and the whole liner'is thrown away, to be replaced by a new one.
Fundamentally the formation of the disposable dustbag is such that the layers of crepe paper are arranged with the creping longitudinal to the direction of the length of the bag. The degree of creping should be at least about 30 to 60 percent. In this manner the bag may be made in a single fit-all size and when it is slipped into a tank or fabric dustbag of the vacuum cleaner, the force of air being drawn through it will distend the bag to conform to the contour of the particular container. The several layers 7, 8 and 9, or as many as it may be desired to use, are preferably formed of extremely thin porous tissue paper, of the texture of commercial cleansing tissues, which do not have sufficient strength per se to withstand the rush of the air current drawn through the vacuum cleaner. In fact, it is preferable that the bag be formed of very porous paper in order that no serious resistance to the air fiow through it be encountered. The strength for holding the bag and preventing its being torn is provided by the net 4. A thin cellulose layer could be placed between the tissue paper larninations 7 and 9. In this fashion, the tissue paper plus the layer of cellulose fibers in the bag structure provide a very effective filter for efficiency in catching all of the dust picked up by the vacuum cleaner.
In this way one does not contact dust and no clouds of dust can arise either, since when removing the dustcatcher its open end is gathered and closed. No dust penetrates into the original dustbag of the vacuum cleaner so that the fitting of the new dust-catcher can also be done hygienically.
What is claimed is:
1. A disposable liner adapted for use with a dust catcher bag within a vacuum cleaner dust catching compartment, said liner comprising the combination of a plurality of layers of creped porous tissue paper, said layers of paper being formed into a bag open at one end, a loose net enclosing said tissue paper bag with a section thereof extending beyond and around the open end of said tissue paper bag, said net being sewed to the tissue paper bag around the circumference of the opening.
. a 3 a 2. The combination in accordance with claim 1 in which. the bag is formed of two halves sewed together along a longitudinal section through said bag.
