DETAILED DESCRIPTION OF THE DRAWINGS

(7) Reference is initially made to FIG. 1.

(8) FIG. 1 shows a typical skin treatment device 1 with a base 2, which can be held in the hand, wherein the base 2 has on its upper end a shoulder 3 (illustrated in dash-dotted fashion since it is concealed), onto which a skin electrode 4 in the form of a cap 5 can be clipped and secured by means of a clip not shown here. However, the invention is not only applicable to skin treatment devices with an interchangeable cap 5 but also to devices where the cap is designed in one piece and integral with the base 2.

(9) A hand electrode 7 which is in contact with the hand when the base 2 is gripped is located on the back side of the base 2 not visible here. Furthermore, situated in the base 2 there is a power source in the form of, e.g., batteries or rechargeable batteries, the terminals of which can be brought into contact with the two electrodes 4, 7 such that, when the skin electrode 4 is placed on the skin, a closed circuit via the body of the person is established. The cap 5 has an elongate form, which tapers from the foot region to the head, wherein the head typically merges into a half-cylindrical edge that can be guided over the skin.

(10) Slight bulges of the edge or a cap in the form of a comb are also conceivable, with the ends of the prongs, however, likewise being enveloped by a half cylinder.

(11) In order to make the cream with an active ingredient available, provision is made of a ring 10 as per FIG. 2. The latter has an oval shape with two longitudinal sections 11, which are interconnected by way of arches 12, wherein a strip 13 that serves as a carrier material for a cream extends from the outer side of one longitudinal section 11 to the outer side of the other longitudinal section 11.

(12) The inner contour of the ring 10 is matched to the foot region of the cap 5 such that the ring 10 can be placed there with a tight fit, the strip 13 extending over the head of the cap 5. The carrier material can be a strip 13 made of a sponge, a fabric or a felt.

(13) To secure the ring 10, small latching lugs 14 are provided in each case on the inner side of the ring, in the center of the longitudinal section 11, the latching lugs ending in a sharp edge and thus engaging in a gap 15 between the base 2 and the edge of the cap 5, as shown in FIG. 6.

(14) However, the latching lugs can also engage behind holding edges on separately formed pockets in the device.

(15) In order to ensure sufficient mobility of the latching lugs 14, however, these are let into the bottom of a respective transverse groove 16 in the inner side of the longitudinal section 11 of the ring 10, with their tip slightly protruding beyond the edge of the groove.

(16) The rings 10 with the soaked strip 13 form additional parts which can be purchased separately from the device, packaged in so-called blister packs 20.

(17) As shown in FIG. 3, a blister pack 20 consists of a shell 21 with a circumferential depression 22, in which the ring 10 is inserted, wherein, in accordance with FIG. 4, which shows a cross section through the ring 10, the strip 13, proceeding from the longitudinal sections 11 of the ring 10, is initially directed downward in the direction of the bottom of the circumferential depression 22 and then extends in an arch through the inner region of the ring 10. This obtains a compact grouping which keeps the blister pack volume low.

(18) The shell 21 is typically sealed by an opaque or transparent film, not shown here.

(19) Before the ring 10 is inserted into the blister pack, the former is soaked with a cream that contains an active ingredient. Sealing the shell 21 with a film prevents the carrier material from drying up.

(20) For use, the film is removed, the ring 10 is gripped by its arches 12 and—as shown in FIG. 5—clipped onto the cap 5 until the latching lugs 14 clip into the gap 15 between the cap 5 and the base 2 as per FIG. 6. This ensures a sufficient hold of the ring 10 on the device so that the head of the cap, over which the strip is stretched, can be guided over the skin without the ring 10 detaching from the device.

(21) After the treatment, the ring 10 can be gripped by the arches 12 again, can be pulled off the cap and can be subsequently disposed of.

(22) The rings 10 can be designed in different colors for the purpose of indicating the type of active ingredients of the cream in the carrier material.
