Abstract

An article for mopping-up spilt liquids comprises a container holding absorbent material and having walls at least a portion of which are permeable to the liquid to be absorbed. The container may be a sack, pillow or bag of sheet material such as paper or a woven or non-woven fabric. The absorbent material may be perlite, ball clay, fullers earth, bentonite, or verminculite, or a mixture thereof. The article may be used for mopping-up spilt liquids such as water, oil, dilute acids or alkalis and non-aqueous solvents in factories or workshops.

Description

SPECIFICATION Mopping-up of liquids This invention relates to the mopping-up of liquids, for example spilt liquids in factories, workshops, etc.
The prompt and efficient mopping-up of liquids spilt in factories, workshops, laboratories and similar places is desirable for the sake of both safety and cleanliness. The present invention aims to permit the mopping-up of spilt liquids in an efficient and convenient manner and provides a container holding a solid material capable of absorbing a liquid to be mopped-up, at least a portion of the walls of the container being of a material permeable to the liquid to be absorbed. The invention also provides a method of mopping-up liquids by use of absorbent material held in such a container.
The container is preferably deformable and may be constituted by a sack, pillow or bag of sheet material, such as paper or woven or non-woven fabric. The container is, advantageously, also absorbent. A particularly suitable material is a nonwoven synthetic material made from viscose rayon. Such material can be obtained from Chicopee Limited, a wholly-owned subsidiary of Johnson & Johnson Limited of Grafton Way, Baskingstoke, Hampshire RG22 6PM. The gauge of the material is about 0.5 mm, or some other suitable value.
The paper or cloth material may be glued or otherwise made-up into a bag, pillow or sack which is charged with the absorbent material and sealed by, for example, gluing. The outer surface of the sack, pillow or bag may carry printed information indicating, for example, the contents of the bag or the type of spilt liquid for which it is intended to be used.
Sacks, pillows or bags according to the invention preferably measure at least 10 cm by at least 10 cm in plan and have a maximum thickness when filled of at least 5 cm. The containers may range in size up to about 1 m by 1 m in plan and to about 20 cm in thickness when filled. The bags may contain between about 200 g and about 10 kg of absorbent material. Particularly convenient sizes fall within the range of from 15 cm by 10 cm by 5 cm thick to about 70 cm by 60 cm by 15 cm thick.
Such bags contain between about 250 g and 5 kg of absorbent material.
The absorbent material is conveniently a particulate, for example powder or granular, material, is preferably the amorphous volcanic glass material known as perlite and, more preferably, expanded perlite. This latter material can be produced by crushing mineral perlite and subjecting the crushed material to heat and pressure which cause the crushed material to expand rapidly to form the absorbent material. The fine portion of the perlite so produced is preferably used.
However, the absorbent material used in the present invention is not limited to perlite: it may also be, for example, another mineral material, such as, for example, ball clay, fullers earth, bentonite or vermiculite. Mixtures of different absorbent materials may also be used.
The particle size of the perlite or other absorbent material is preferably less than 3 mm, more preferably less than 2 mm and most preferably less than 0.5 mm.
In use, the permeable wall portion of a container of the present invention is placed in contact with a liquid to be absorbed, for example spilt oil or chemical, and, preferably, moved so as to mop-up the liquid. The spilt liquid permeates the wall of the container and is absorbed by the absorbent material. If the container is a sack, pillow or bag, it can be easily deformed to bring fresh portions of its surface into contact with the liquid and can also be kicked or pulled around to absorb the spilt liquid.
With the present invention the disadvantages of the use of loose absorbent materials for moppingup liquids can be overcome: sweeping-up of loose material is avoided and the containers of the present invention are easily handled (if necessary whilst wearing protective clothing) and disposed of after use. Loose dust or particulate material is avoided and the particular advantage of elimination of dusty or particulate contaminated material, which could otherwise be blown around a workshop or factory and be inhaled by, or otherwise come into contact with, persons working in the workshop or factory, is achieved.
An exemplifying embodiment of the invention is shown in the drawing. The bag illustrated is about 30 cm by 35 cm in plan and, when charged with about 500 g of expanded perlite, has a maximum thickness of about 7 cm.
The bag is formed by folding and gluing a suitably shaped and dimensioned sheet of non-woven man-made viscose rayon material of about 0.5 mm gauge. Opposite ends of the sheet are first overlapped at 10 and glued together along the line 12.
A bottom flap 14 is then folded-over along the line 16 and glued-down to seal the bottom of the bag.
After charging with perlite, the top of the bag is sealed by folding-over a top flap 28 along the line 20 and gluing the flap 18 to the surface of the bag.
The outer surface of the bag can carry printed information applied before folding and gluing of the sheet.
The bag may be used for mopping-up spilt liquids such as, for example, water, oil, dilute acids or alkalis and non-aqueous solvents.
Containers according to the present invention are preferably non-flammable or treated with a flame retardant. This makes the container safer in use, particularly after it has absorbed a flammable material. The non-woven synthetic material made from viscose rayon and mentioned above can be treated with a flame retardant and the material of the bag of the exemplifying embodiment is therefore preferably one which has been so treated.
