DESCRIPTION:

BRIEF SUMMARY
The invention relates to a tampon blister pack, particularly for female hygiene.
In some cases it is desirable or necessary in connection with tampons which are suitable in particular for female hygiene to use active substances which either facilitate the application of the tampon or are to fulfill therapeutic or diagnostic purposes. Thus, the introduction of tampons, for example, causes discomfort, in particular when the period is subsiding. Because insufficient moisture is then present, sliding of the tampon is impeded by the friction between the walls of the organ and the outer surface of the tampon.
It is known to coat tampons, and particularly the rounded introduction ends of such tampons, with active substances, such as lubricants or pharmaceutical substances for therapy or diagnosis. However, a tampon which has been coated in this way a long time before use can have the disadvantage that the active substance applied to the tampon is absorbed in the course of time by the highly absorbent tampon and that there is thus the danger that the purpose intended with the active substance will not be achieved. It is furthermore known to surround tampons with a solid substance which penetrates the tampon to a very small extent or even not at all. These tampons have the disadvantage that the rate of absorption is severely restricted by the closed coating. In the case of intermittent bleeding there is then a risk of the secretion flowing past the non-expanded tampon.
The invention is therefore based on the problem to provide a tampon blister pack, in particular for female hygiene, of such a design that the active substance, preferably a lubricant, is applied to the tampon, in particular to its front zone, only immediately before use so that substantially the entire amount of the present active substance will be available for the purpose to be achieved.
This problem is solved by the invention by a depot located at a distance from the tampon. The depot can be arranged in a cup of the deep-drawn film which in the area of the main deep-drawn film is open or covered or is arranged separate from the latter. The depot can be uncovered by opening the blister pack and then be brought into contact with the introduction end of the tampon, or it can be squeezed out by finger pressure in the direction of the introduction end of the tampon and be applied thereto before opening the blister pack and using it.
The features of the tampon blister pack according to the invention can be seen from the patent claims.
In the following text, preferred embodiments of the tampon blister pack according to the invention are explained by reference to the drawings in which:
FIG. 1 shows a longitudinal section of a tampon blister pack having an open cup provided in the deep-drawn film and containing the depot,
FIG. 2 shows a longitudinal section of the pack in FIG. 1, the tampon being immersed in the cup with the depot;
FIG. 3 shows a longitudinal section of a tampon blister pack having a covered depot cup in the deep-drawn film;
FIG. 4 shows a longitudinal section of the pack in FIG. 3, at the start of the opening phase;
FIG. 5 shows a longitudinal section of the pack in FIG. 3 in the opened position;
FIG. 6 shows a longitudinal section of a tampon blister pack having an asymmetrical interleaf located between the bottom of the deep-drawn film and the tampon;
FIG. 7 shows a cross-section along the line VII--VII of FIG. 6;
FIG. 8 shows a cross-section of a tampon blister pack having an interleaf which is drawn up on one longitudinal side of the tampon up to the cover film;
FIG. 9 shows a longitudinal section of a tampon blister pack in which a cup for the depot is separated from a deep-drawn recess for the tampon;
FIG. 10 shows a plan view of the pack in FIG. 9;
FIG. 11 shows a longitudinal section of the pack in FIG. 9 in the opened position, the tampon being immersed into a cup;
FIG. 12 shows a longitudinal section of a further embodiment of a tampon blister pack having a gripping tab designed as depot;
FIG. 13 shows a plan view of the blister
