Abstract

Object of the invention is to provide at low cost, a glove suited for washing and wiping. This is obtained by making the glove with its outer side from plastic-film and by making the inner side from two substantially equally sized parts where the part (5) which is closest to the glove opening (2) consists only of plastic-film and where the part which is closest to the fingertips consists of only polyurethane cellular plastic (9) flame laminated, upon plastic-film and by welding together these two parts along the edges (7, 10) parallel to the glove opening (2) before the inner and outer sides of the glove are welded together along their edges (4). <IMAGE>

Description

SPECIFICATION Glove and a method for producing such glove For washing persons or for disinfection of equipment for medical and dental use a small towel made from foamed plastic (cellular piastic) or from wet strength paper is frequently used. This towel is often held by means of a simple glove made from plastic sheet film. This invention refers to a glove made from plastic film and having at its inner side a surface cover of cellular plastic. The invention also refers to a method for producing such glove. The invention has the characteristics as specified in the claims.

The invention will be described more in detail with reference to the accompanying drawing.

Figure 1 shows a glove according to the invention; Figure 2 shows the glove according to Figure 1 but a little bit opened and seen in section A-A; Figure 3 schematically shows a manufacturing method in a plan view; Figure 4 shows the method of claim 3 in a side view.

In the Figures 1 and 2, which show a glove for the right hand, reference numeral 1 designates a plastic sheet film which constitutes the outer side of the entire glove. The outer side is in the opening of the glove 2 limited by means of the straight edge 3 and in the rest by the edge 4. The inner side of the glove consists in the portion thereof which is close to the opening 2 solely of a plastic film 5 with the limit edge 6 at the opening 2 and a limit edge 7 parallel to said edge. The inner side of the glove consists in the portion thereof which is remote to the opening of a plastic film 8 from flame laminated polyurethane cellular plastic 9.

The cellular plastic is for clarity reasons shown with exaggerated thickness in the drawing. The plastic film 8 and the cellular plastic 9 have the same contours and are limited towards the opening 2 of the glove by a straight line 10 parallel to the opening edge 6. The plastic film 8 overlaps the plastic film 5 and in the overlapping area the two plastic films are welded together. An overlapping of 4 mm is sufficient. The plastic films 5 and 8 are connected at the edge 4 of the outer side by means of plastic welding.

In Figures 3 and 4 reference numeral 11 designates as a central path consisting of polyurethane cellular plastic flame laminated upon plastic film. 7wo side paths made from plastic film only are denoted 12 and 13. The middle path overlaps the two side paths in the areas 14 and 1 5.

At the manufacturing the central path is welded together with the side path in the overlapping areas to produce a composite upper path. This upper path is piaced over a lower path 1 6 consisting only of plastic film. A welding with contemporaneous cutting along the contours 1 8 and 1 9 of the gloves is then provided in one production station. In this station one glove 20 and one glove 21 are thus released. The two gloves are oppositely directed. The upper limits 22 and 23 of the gloves extend considerably beyond an imaginary central line 17. The completed gloves are drawn out from the path in directions indicated by the arrows 24 and 25. The removal of the gloves can alternatively take place in a subsequent station. The reference numeral 26 designated the empty spaces after removed gloves and the remaining material is denoted 27.

The numeral 28 designates a heating block and numeral 29 designates a counter block. The plastic film 12 is welded to the central path 11 between these blocks. The welding can take place at a relatively low temperature whereat a very high temperature is needed for the cuttingwelding operation.

It has proven impossible to glove a central tape of cellular plastic to a wider plastic film at reasonable costs and with sufficient adherence.

Flame laminating cellular plastic upon plastic film is a complicated method which has to be preformed in big scale and with expensive equipment to give reasonable costs for making such a product. For this reason only a few manufacturers make such material. The laminates are supplied in rolls with big width which then easily may be cut to narrow rolls. A laminate with 2 mm thick cellular plastic is about 10 times more expensive than a simple plastic film.

Most of the disposable gloves are about 300 mm in length to prevent water from entering through the glove opening. By using laminate only for the finger portion of the glove and by arranging the upper limits 22 and 23 considerably beyond the central line 17 at the manufacturing procedure an important reduction of the expensive laminate is achieved. The cellular plastic preferably extends about half the distance from the upper limits 22 of the glove to the glove opening. This area is sufficient for washing and wiping and this area almost covers the area which can be wiped by the hand. It is an advantage that the cellular plastic is not located outside the area which can be squeezed by the closed hand since almost all water in the glove can be squeezed off.

Additionally is achieved that for instance one hundred gloves take only about half the volume which the same number of gloves should have required if they had been covered by cellular plastic over their entire inside. It is assumed that the parts of the glove which are not provided with cellular plastic folded over the parts provided with cellular plastic. The cellular plastic is about one hundred times thicker than a simple plastic film.

It is self-evident that the cellular plastic can be impregnated with a soap solution like disposable washing sponges. It is also self-evident that the welding of the gloves can be performed according to any suitable technique used for cutting-welding of plastic film. The thin cellular plastic layer (1-3 mm) does not disturb such a process. The welding is suitable carried out by means of constantly heated biocks and can either occur intermittently or according to the well-known rotation principle. It is also possible to arrange welding and cutting at difference stations. The removal of the gloves from the remaining material can also take place in a direction perpendicular to the surface of the paths. The illustrated embodiment of the glove and the described method are only examplifying.

By use of disposal gloves in medical attendance the costs are critical. The present glove is advantageous in that it can be completely squeezed that it occupies a minimum of space in storage and that it can be produced at sufficiently low costs.

Claims

1. A glove consisting of planar plastic films which are welded together at their edges and where the outer side of the glove solely consists of plastic film, characterized in that the inner side of the glove in the part thereof which is closest to the opening consists of a first plastic film, with a straight limit parallel to the open edges of the glove, that the inner side of the glove in the part thereof which is remote to the opening consists of a polyurethane cellular plastic flame laminated upon a second plastic film where the second plastic film and the cellular plastic have the same contours, that the cellular plastic is limited by a straight line parallel to the open edges of the glove and that the cellular-plastic-coated film is welded to the first plastic film along their straight limits.

2. A glove as claimed in claim 1, characterized in that the cellular plastic-coated film overlaps the first plastic film.

3. A glove substantially as hereinbefore described with reference to and as illustrated in the accompanying drawings.

4. A method for producing a glove as claimed in claim 1, characterized in that along each of two opposite edges of a central path consisting of cellular plastic-coated plastic film is welded a side path consisting only of plastic-film, that this welded-together path is then piaced upon a path consisting only of plastic-film and that from the double path so obtained are produced gloves which in pairs are oppositely directed and where the upper limits of the gloves extend a considerable amount beyond a centre line of the path.

5. A method as claimed in claim 4, characterized in that the central path is located such that it somewhat overlaps the side paths and that the central path is welded to the side-paths in the overlapping areas before the inner and oi ter sides of the glove are welded together.
