Abstract

The glove, comprising two walls (1, 2) each of which consists of one sheet (3, 4) of impervious material and of a layer (5, 6) of active material, is characterised in that both sheets (3, 4) of impervious material form, up to the moment when the glove is used, a sealed closed pocket which isolates both active layers (5, 6) from the environment, those layers being secured respectively to said sheets of impervious material, and one of the edges (3a, 4a) of the pocket being openable, during use, for the formation of a glove and for reversing the walls (1, 2) face to face through the opening thus formed so that the active layers (5, 6) are outside and the sheets (3, 4) of impervious material are inside.

Description

REVERSIBLE COMPOSITE GLOVE

The invention relates to a reversible composite glove, that is to say a glove which is composed of at least two different materials and which can be turned over, for its use, so that the inner face becomes the face exterior, and vice versa.

Among these gloves, the invention relates to those of the kind in which one of the layers consists of an impermeable sheet, while the other layer is a treatment layer, for example a layer of nonwoven material.

The invention applies in a particular, but not limiting, manner to gloves of this kind which can be used for body care (beauty, hygiene, prophylaxis), for cleaning, for maintenance, or even for purposes professional, for example industrial or medical.

British patent 1,583,181 already discloses a reversible composite glove, each wall of which consists of a sheet of impermeable plastic and a layer of absorbent material. This glove has a lateral opening for the introduction of the hand and the passage of the wrist. For the use of the glove, it is left in its state of presentation, that is to say that the two waterproof sheets are inside and the active absorbent layers are outside, or, at the on the contrary, as required, the glove is turned over so that the waterproof sheets are on the outside and the active absorbent layers on the inside.

In practice, the glove according to this British patent is in fact a double glove which the user can turn over as required. Due to the existence of the permanent opening made on the glove for the introduction of the hand and the wrist, the two faces of the glove, that is to say the inner face and the outer face, are subjected to the ambient.

Also known, from British patent 899,016, a cleaning pad which is constituted by a pocket of absorbent material which contains soap or the like, this pocket being provided throw it to a gripping means such as a thong or a glove. During use, the water soaks the bag and partially dissolves the soap, the soapy water passing back through the permeable bag for cleaning operations.

A cleaning pad, produced according to this second British patent, in the embodiment in which it is constituted by a glove which externally carries a permeable pocket, is not reversible and, moreover, both its inner face and its outer face are subject in the middle.

The object of the invention is to remedy these drawbacks by proposing a reversible composite glove, in particular for single use, the active layer of each wall of which is, until the glove is used, protected from the external environment.

To this end, the glove according to the invention, comprising two walls, each of which consists of a sheet of waterproof material and at least one active layer, is characterized in that the two sheets of waterproof material constitute, up to 1 use of the glove, a sealed sealed pocket isolating the two active layers from the ambient environment, these active layers being subject respectively to said sheets of impermeable material, and one of the edges of the pocket being able to be opened, in use, for the forming a glove and for turning the walls face to face, through the opening thus formed, so that the active layers are on the outside and the sheets of impermeable material on the inside.

With such an arrangement, since the active layers are, until use, isolated from the outside environment, they are not influenced by them. For example, in the case where the active layers must be used in an aseptic medium, it is ensured that, until the glove is used, these layers will not be soiled by the contaminants of the external medium; as another example, in the case where these active layers carry a treatment product, it is assured, in the same way, that this treatment product, which can react for example with ambient air, will not be degraded during the 'use ; as yet another example, if the active layers are absorbent layers which carry an impregnation product, use, that this product will not be evaporated; as yet another example, if the active layers carry an aggressive product, there is no risk of accident during handling between manufacture and use.

However, the glove according to the invention still has a decisive advantage during use. Indeed, due to the presence of the two waterproof sheets, the user's hand is isolated from the active layers, in the external position, and is therefore sheltered from any treatment product carried by the active layers and / or contamination or aggression from the treated surface.

Preferably, the active layers are set back from the sheets of impermeable material: over-part of the outline of the pocket corresponding to the edge intended to be opened. In this way, one can easily open said edge, for the constitution of the glove, without mechanically degrading said layers. This arrangement also has the advantage that the user, thanks to the two marginal zones which border the opening and which are devoid of active layers, can easily turn the glove over for use, without its fingers come into contact with said layers.

Other characteristics of the invention will appear on reading the description which follows, and with reference to the appended drawings in which:

Figure 1 is a longitudinal section of the glove according to the invention before use;

Figure 2 is a longitudinal section of the glove of Figure 1 open and turned over for use;

Figure 3 is a perspective view showing the first phase of the continuous manufacturing process of the glove according to the invention;

Figure 4 is a section on IV-IV of Figure 3;

FIG. 5 is a perspective view, similar to FIG. 3, showing the second phase of manufacturing the glove according to the invention and

Figure 6 is a perspective view, with cutaway, showing a continuous strip consisting of a succession of adjacent gloves according to the invention ready for use.

The glove according to the invention, shown in Figures 1, 2 and 6 in the finished state, is of the composite and reversible type.

It consists of two walls 1,2, each formed by a sheet of impermeable material 3, 4, for example a polyethylene film mono-oriented, ten microns thick, and at least one layer of active material 5 , 6.

Each layer of active material 5, 6 is subject, at its periphery, to the associated sheet 3, 4 of impermeable material, by a continuous peripheral weld 7, 8. The sheets 3 to 6 are preferably of rectangular outline. In each wall 1, 2, the edges of the sheets 3, 4 and of the layers 5, 6 coincide on three sides, along which the two walls are joined by a weld line or the like 9, while, on the fourth side, the sheet 3, 4 of impermeable material projects beyond the active layer 5, 6 to form a tongue 3a, 4a, having a single thickness.

Along their free edge, the tongues 3a, 4a, are assembled by a weld line 10 which extends over the entire corresponding dimension of the glove, that is to say between the two ends of the weld line 9 spanning the other three sides.

The welding lines are made hot, by partial melting of the material, in particular using ultrasound.

As can be seen in FIG. 1, the waterproof sheets 3, 4 constitute a closed pocket which contains the two layers 5, 6 of active material, this pocket being waterproof thanks to the continuous peripheral closure formed by the welds 9 and 10.

As explained above, the layers 5, 6 of active material are therefore sheltered from the ambient environment from the manufacture of the glove to its use.

When the user wishes to use the glove of FIG. 1, he destroys by hand the assembly produced on one side by the welding line 10, this destruction being able to be done by tearing, by bursting or even using '' a cutting tool, for example a pair of scissors. When the two tabs 3a, 4a, have thus been separated from one another, the user can return the glove through the opening 11 thus formed, to give it the conformation represented in FIG. 2 for which the sheets 3, 4 of impermeable material are inside and the layers 5, 6 of active material are outside .

As also explained above, when the user uses the glove, his hand, which is placed between the sheets 3, 4 of impermeable material, is isolated, on the one hand, from the layers 5, 6 of active material and, from on the other hand, of the treated surface.

According to the use for which the glove according to the invention is intended, the layers 5, 6 of active material can be impregnated with a treatment product or, on the contrary, be virgin.

By way of example, the layers 5, 6 of active material can be made of an absorbent non-woven material, based on natural or synthetic fibers.

The glove according to the invention, shown in FIG. 1 in its state of presentation, that is to say until it is used, can be dispensed individually, for example in the form of a stack of deployed gloves or in the form of a pile of gloves, each folded in half, alternatively, with interpenetration. However, it can also be distributed continuously, for example in the form of a strip, such as that shown in FIG. 6, this strip being in a roll or folded in accordion. In this continuous presentation mode, the adjacent gloves are separated by a line of weakness 12, for example a pre-cut, carried out at the same time as the transverse welds 9.

FIGS. 3 to 5 show the main phases of a particular method of manufacturing the glove according to the invention.

In a first phase (FIG. 3), a sheet 3 (4) of impermeable material and a layer 5 (6) of active material are continuously superimposed, so that two of their longitudinal edges are superimposed while, on the other side, the sheet 3 (4) protrudes from the layer 5 (6), to form the handling tongue 3a (4a). The sheet 3 (4) and the layer 5 (6) are continuously assembled by two longitudinal welding lines 7 (8).

After this first operation, a wall 1 (2) is therefore obtained consisting of a sheet of impermeable material 3 (4) bearing, over part of its width, a layer of active material 5 (6), the sheet 3 (4) having an excess of width 3a (4a). After this operation, the layer 5 (6) can, if necessary, receive a liquid, pasty or solid treatment product.

When two identical continuous walls have thus been formed, as shown in FIGS. 3 and 4, they are superimposed so that the layers 5, 6 are in facial contact, that the sheets of impermeable material 3, 4 are on the outside and that the tongues 3a, 4a are located on the same side. The two walls are then assembled by the longitudinal welding line 9, opposite the tongues 3a, 4a, this welding line being in superposition or adjacent to the two superimposed welding lines 7, 8 already produced on this side, and transverse welding lines 9, at regular intervals. At the same time, the welding line 10 is produced to close the assembly.

To facilitate the separation of the gloves individually, the welding lines 9 are preferably double, the two welding lines being separated by the weakening line 12, for example a precut.
