Abstract

The container comprises two sheets of thin material sealed along its edges. A double sided adhesive layer 2, affixed to its back forms an attachment of the container to the surface being drilled and a seal between the container and surface. A hole relative to size of hole being drilled passes through all three layers. The hole is centred over the spot to be drilled to allow the bit to pass through the container. During the drilling process debris is extruded from the material being drilled into the container. A strip of containers may be provided, each removable from the next by perforations. <IMAGE>

Description

DRILLING DEBRIS RETENTION CONTAINER This Invention relates to a container used to retain debris extruded from a hole during drilling operations.

During a drilling operation debris is extruded from the hole being drilled as the drill bit is rotated. This excess material is unwanted and needs to be removed from the surface being drilled and from other surfaces the debris happens to fall upon.

The use of the invention during the drilling process retains this unwanted debris, so stopping the debris soiling surrounding surfaces such as wallpaper, painted surfaces, brickwork or woodwork. The bag also stops the debris falling onto fabric surfaces such as carpets, furniture and clothing.

The invention also lessens the hazards of drilling dust becoming airborne leading to contamination of the air and other surfaces away from drilling site.

The debris retention bag would make the operation less messy and also quicker due to time saved cleaning up after operation.

A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which: Figure 1. shows a frontal elevation of the bag, as would be seen affixed to the surface being drilled.

Figure 2. shows a sectional side elevation of the bag.

Figure 3. shows how the bag is used in conjunction with a drill in a drilling operation. The figure shows how the debris collects in the bag Figure 4. shows how the bags could be made from a long length of polythene tube seperated into seperate bags by sealed. Drierated edges, 7.

Figure 5. shows section of figure 4.

Referring to the drawings Fig.l and Fig.2. These show the construction of the bag. The main body of the bag is made of two sheets of suitable material such as thin polythene, 3. sandwiched together and sealed along their perimeters, 4.

For ease of production the bags could be made from a tube of thin material, ie, polythene, sealed and perforated in such a way as to allow individual bags to be torn off the strip as needed, this is shown in fig. 4 and fig. 5.

where the sealed joint 4 seperates the bags and perforation 7 enables the bags to be torn from the strip maintaining the sealed edge 4 of the bag.

Fastened on to one side of the bag is an adhesive layer 2. This attaches the bag to the surface being drilled and also seals the edge of the hole to the bag.

A hole is present through the 2 layers of polythene and also through the adhesive layer.

The size of the hole is relative to the size of the hole being drilled.

The size and shape will vary according to size of the hole and the amount and type of debris expected from the drilling operation.

The operation of the bag is shown in Figure 3.

The bag is affixed to the wall so that the hole 1 through the bag is centred on the spot to be drilled.

The adhesive layer affixes the bag to the wall it also forms a seal around the edge of the hole when the bag is pressed on to the surface to be drilled so that the extruded debris falls into the bag.

The hole is bored by drilling the drill bit through the hole 1 in the bag.

When the drilling process is complete the drill bit is extracted from the hole and the bag is peeled from the drilled surface and desposed of along with the debris.

Claims

DRILLING DEBRIS RETENTION CONTAINEP.

CLAIM 1. A container sealed around its perirot-er with a hole through the container to allow free passage of a drily bit. A container to catch and retain debris extruded from a hole during a drilling process.

There being a means of sealing the container to the surface being drilled so as to ensure debris falls into the container and not onto the surface being drilled.
2. A container as descried in claim 1 --. or a transparent material to atlo.

the spot being drilled to be secn.
3. A container as in claim 1 or claim 2 with the seal in the form of a self adhesive laver around the perimeter ,f the hole in the bag or container.

The container could be of sufricen capacity to be used for one or more holes.
4. A container as claimed in claims 1. or 3 made of thin flexible materia in the form of bags in strip: form, esh one disposable from the other, having a seal as described in claim 3.
5. A container as in claim 1 made from more rigid material such as clear formed plastic, having an adhesive se@@@ as claimed in claim 3. The container so constructed in@@@@@@@@@@ container for wall ancho plugs and to allow the container @@@@ used as described in claim 1
6. The container as described in clair- 3. The size being capable or retaining the accumulated debris from the amount of holes drilled to use up the number of plug containers within that container when sold.
