Description

DESCRIPTION OF THE FIGURES

[0102] The invention will be better understood on reading the following description of nonlimiting implementations thereof and on examining the appended schematic and partial drawings, in which:

[0103] FIG. 1 shows alone a perspective front view of a double unitary block usable according to the invention,

[0104] FIG. 2 shows alone a perspective side view of the block of FIG. 1, only the button cells being shown at the front of the figure,

[0105] FIG. 3 is an axial cross section through a detail of embodiment of an article according to the invention equipped with a block according to FIG. 1,

[0106] FIG. 4 shows a front view of a first mask according to the invention said mask being equipped with a block according to FIG. 1,

[0107] FIG. 5 shows a front view of a second mask according to the invention, said mask being equipped with a block according to FIG. 1.

[0108] In the figures, for the sake of clarity, the various elements have not always been drawn to scale.

[0109] FIG. 1 and FIG. 2 show a unitary block 12 of axis Y.

[0110] The unitary block 12 mainly includes: [0111] a source of electrical power formed by two button cells 1 and 11, and [0112] a repositionable adhesive material 5 placed on a segment of the exterior surface 33 of the block 12.

[0113] Each battery 1 and 11 is flat. It has a dome shape of axis X (X respectively) the bottom of which forms: [0114] the negative pole 106 for the battery 1, [0115] the negative pole 113 for the battery 11.

[0116] The portion of the dome opposite the bottom with respect to the axis X (X respectively) forms: [0117] the positive pole 102 for the battery 1, [0118] the positive pole 116 for the battery 11.

[0119] Each battery 1 and 11 has a diameter comprised between 4 and 40 mm and a height comprised between 0.8 mm and 10 mm. The batteries 1 and 11 typically each have an operating voltage of more than 1 V, 3 V for example.

[0120] Preferably, a lithium button cell is used because it has a high discharge plateau and excellent discharge supply characteristics. The degree of utilization of the active material of the positive or negative electrode is considerably improved and the capacity of the battery is increased.

[0121] Button cells usable according to the invention are for example described in documents WO201310682 or WO2012000303.

[0122] The unitary block 12 includes two housings 31 and 311 that are intended to receive the battery 1 and the battery 11, respectively. These housings 31 and 311 are delineated by a repositionable adhesive 5, for example a silicone, sandwiched between a conductive sheet 6 and an insulating sheet 4. A flexible and resistant protective sheet 7 is fastened to the conductive sheet 6. This protective sheet 7 adheres to the repositionable adhesive 5.

[0123] FIG. 3 shows: [0124] the positive pole 102 of the battery 1 making contact with a positive electrode 3, [0125] the negative pole 106 of the battery 1 making contact with the conductive sheet 6, [0126] the positive pole 116 of the battery 11 making contact with the conductive sheet 6, [0127] a negative pole 113 of the battery 11 making contact with a negative electrode 2.

[0128] The adhesive flexible material 5 is insulating. It separates the positive pole 102 of the button cell 1 and the negative pole 113 of the button cell 11 from the sheet 6.

[0129] The insulating sheet 4 may include any electrically insulating material, for example chosen from insulating thermoplastic materials such as the polyamides, the styrenics, the polyolefins or the vinylics.

[0130] Each cell 1 and 11 delivers a current of 3 V for example, thereby making a sum of 6 V in total, making it possible to observe an effect of the treatment over a large area by the mask for example.

[0131] In FIG. 4 a mask has been shown that is configured to cover at least some of the face, and that includes a carrier 50 formed by a first portion 30 to be placed on the face and by an extension 40 to be placed under the chin.

[0132] The unitary block 12 is located between the first portion 30 and the extension 40.

[0133] It may be placed in a first direction with respect to the electrodes in order to provide care for the skin, and in a second direction in order to clean the skin.

[0134] The mask may, as shown in FIG. 5, include the unitary block 12 of FIG. 1 in the region of the forehead, and a carrier 50 formed of two portions: a right-hand portion 40 and a left-hand portion 41.

[0135] It is for example possible to connect: [0136] a negative electrode 2 of the right-hand portion 40 to the () pole of the button cell 11, and [0137] a positive electrode 3 of the left-hand portion 41 to the (+) pole of the button cell 1.

[0138] It is also possible to switch the electrodes in order to change treatment type as the block 12 is repositionable. Simply by flipping the unitary block 12 the treatment is changed from a skincare treatment to a skin-cleaning treatment.

[0139] As the mask is divided into two, the current applied to the face is increased and the effect of the treatment is improved.

[0140] The invention is not limited to the examples that have just been described.

[0141] Particularities of embodiment of the illustrated examples may be combined within variants that have not been illustrated. The structure of the electrodes and the area that they occupy may in particular be different. It is possible to switch the electrodes as the unitary block is repositionable. The article may be used in a penetration or stimulation mode. Other types of batteries or cells may be used.
