| 1. | A disposable container for holding waste liquids for disposal, said container comprising an impermeable baglike body which when in use contains absorbent material secured to the inside thereof, a pair of spaced handlelike loops extending from the rim of said body and a pair of ties extending from said rim at positions intermediate said loops, said ties being capable of being tied together to effect a first closing action on the bag and said loops being capable of being tied together to effect a second closing action on said bag. |
| 2. | A container according to Claim 1, wherein the absorbent material comprises at least one pad secured to the outside of the baglike body during manufacture and arranged to be accommodated inside the baglike body upon inversion of the baglike body, prior to use. |
| 3. | A container according to Claim 2, wherein the pad is secured to the closed end of the baglike body when flattened so that a substantial portion of the pad projects beyond the end of the baglike body. |
| 4. | A container according to Claim 3, wherein said substantial portion is substantially half. |
| 5. | A container according to any one of Claims 2 to 4, wherein the pad is spot glued to the baglike body. |
| 6. | A container according to any preceding claim, wherein the baglike body is produced from a tubular member folded to effect longitudinal pleats along opposite sides of the tubular member and sealed it at one end. |
| 7. | A container according to Claim 1, wherein the absorbent material is in particulate form SUBSTITUTE SHEET adhesively secured to the inner wall of the baglike body. |
| 8. | A container according to any preceding claim wherein the baglike body may comprise polythene and the absorbent material comprises paper. |
The present invention relates to disposable containers for receiving liquid waste material and for disposing of it in a safe manner. Sick bags for aircraft and plastic liners for children's portable potties generally suffer from the disadvantage that when filled with a liquid waste it is difficult to dispose of the container without spillage. It is an object of the invention to provide an improved disposable container.
According to the present invention there is provided a disposable container for holding waste liquids for disposal, said container comprising an impermeable bag-like body which when in use contains absorbent material secured to the inside thereof, a pair of spaced handle-like loops extending from the rim of said body and a pair of ties extending from said rim at positions intermediate said loops, said ties being capable of being tied together to effect a first closing action on the bag and said loops being capable of being tied together to effect a second closing action on said bag.
Disposable containers embodying the invention, will now be described, by way of example, with reference to the accompanying diagrammatic drawings in which:
Eigure 1 is a front elevation of a first container embodying the present invention; Pigure 2 is a front elevation of a second container embodying the invention immediately after manufacture but prior to inversion into a ready-for- use state; and
Eigure 3 is a side elevation of the container for Eigure 1 with the loops slightly opened
out and the ties turned down for purposes of illustration.
The disposable container or pouch shown in Eigure 1 is made of a tube of polythene with longitudinal gussets or pleats 2 and 4 formed along opposite sides. The inner most extent of each gussett is shown dotted. The lower end 6 of the tube is heat sealed to close off the lower end in a water tight manner. The upper end of the tube is also sealed and a "¥" shaped recess cut centrally of the upper end to leave left and right lateral loops 8 and 10 with sealed ends and with intervening ties 12 and 14 lying between the loops. The outer longitudinal sides of the loops are cut to complete the formation of the loops.
Housed within the bag-like body defined by the tube, is a pad 16 of absorbent material. The pad 16 may be of paper, high absorbtion pulp or cotton composition or of any other liquid absorbent material. The tube and/or the liner may be treated with a perfume and/or a disinfectant composition.
The pad is secured in place by spot glueing 20 or other means well known to persons of ordinary skill. Placing the pad 16 into the bag-like body may present problems if mass production processes are used.
In this event the pad 16 is secured to the outside of the tube as shown in Figure 2 with approximately half of the bag projecting beyond the lower sealed end of the tube. Prior to use the bag¬ like body formed by the tube is inverted (turned inside out) and the pad folded in half so that it now nests inside the lower portion of the bag-like body. The container is now ready for use.
SUBSTITUTE S ' I £___« _•>•
In operation the loops are used to open out the rim of the bag-like body, and to hold it ready for use. When liquid waste has been deposited in the container, the absorbent material acts to soak up the liquid.
To dispose of the container, the two ties 12 and 14 are knotted together to draw the adjacent parts of the rim together. The two loops 8 and 10 are then knotted together to bring the adjacent parts of the rim together. The double knotting action assists in securing the pad and the waste material within the body-like bag and so the container can now be safely disposed of in a dustbin or garbage can. In a modification it will be appreciated that instead of using a pad in the body-like bag, the tubular material itself may be made of a multilayer material in which the outer layer is of impermeable material and the inner layer is of an absorbent material. Instead, the inner face of the bag-like body may be sprayed with adhesively coated particles or fragments of absorbent material so that the inner face of the body bears an absorbent lining.
