BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to packaging material for a sanitary napkin or like article wherein the sanitary napkin has an at least partially adhesive outer service and is folded so that this adhesive surface faces towards the packaging material.
BACKGROUND OF THE INVENTION
Sanitary napkins and panty protectors are often packaged in a folded state in units for one-time use only, so that they can be carried hygienically and unnoticed for later use in a handbag for instance. The outer surface of a sanitary napkin or a panty protector is coated at least partially with an adhesive, so that the napkin or panty protector can be fastened to the inside of a pair of panties. To avoid the coating preventing the package from being opened or to avoid the coating being destroyed by the packaging material, it is normal practice to protect the adhesive coating with a release paper or release foil. An alternative method of solving this problem is to coat the packaging material with a release agent, for instance with a siliconized resin. As an example of this method EP-A1-0 357 000 is referred to. However, both of the solutions are relatively expensive.
OBJECTS OF THE INVENTION
One object of the present invention is to provide a packaging material for a single sanitary napkin package or a single panty intended for one-time use only with which no release agent is required and with which the adhesive coating on the sanitary napkin or the panty protector need not be protected against destruction by the packaging material.
SUMMARY OF THE INVENTION
These objects are achieved in accordance with the invention with packaging material of the kind defined in the introduction and characterized in that the packaging material, on the surface facing the adhesive outer surface of the sanitary napkin, is provided with a multiple of projections in order to present a small surface area for contact with the outer surface of the sanitary napkin.
According to a first embodiment of the invention, the packaging material is a melt-bonded patterned nonwoven material.
In alternative embodiments of the invention, packaging material is comprised respectively of a laminate of plastic film and nonwoven material, plastic film which is covered on one side with small projections, or a plastic film which includes on one side longitudinally extending and transversely extending ribs which together form a net structure.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will now be described with reference to the accompanying drawings, in which
FIG. 1 is a view from above of a sanitary napkin placed on top of a packaging blank;
FIG. 2 is a cross-sectional view showing a first folding step in the manufacture of a single-article package with a starting point from the packaging blank in FIG. 1; and
FIG. 3 is a cross-sectional view of a single-article package in accordance with a first embodiment of the invention.
FIG. 4 is a cross-sectional view taken along line IV--IV of FIG. 2.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 shows a sanitary napkin 1 placed on top of a sheet 2 of packaging material. The side of the sanitary napkin 1 distal from the viewer of FIG. 1 is coated with an adhesive so that the napkin can be fastened to a pair of panties from the inside, and thus adheres to the inner surface of the sheet 2. In order to provide a single-pack sanitary napkin with a starting point from the configuration shown in FIG. 1, the unit consisting of the napkin 1 and the sheet 2 is first folded about the contemplated fold line A--A shown in broken line in FIG. 1, so as to give the unit 1, 2 the configuration shown in FIG. 2. The unit 1, 2 is then folded around the contemplated fold line B--B shown in a broken line in FIG. 1, to obtain the package configuration shown in FIG. 3. The sanitary napkin is held together in this folded state with the aid of a fastener tape 3, which fastens that part of the sheet 2 which has been folded around the line B--B to the part that was earlier folded inwards about the line A--A.
