An expandable bag catamenial tampon and spreading tampon applicators for such a tampon are disclosed. The catamenial tampon is in the form of a soft, conformable, hollow bag. The applicator is capable of inserting the tampon into the vaginal tract and spreading the tampon open within the vaginal cavity. The applicator has an applicator element with a leading end and a trailing end. The bag-like tampon is placed over the leading end of the applicator when the tampon is in a flaccid initial configuration which defines an initial width, and the applicator is used to spread the tampon to a greater deployed width. In one embodiment, the applicator comprises tube having an interior and a flexible material which has one end that is formed into a flexible and expandable loop. The flexible loop is slidably mounted within the tube. The flexible loop is contained inside the tube until it is desired to deploy the tampon. When it is desired to deploy the tampon, the flexible loop with the tampon thereon is pushed out the expulsion end of the tube. The flexible loop expands laterally and spreads the tampon open within the vaginal cavity.

The present invention provides a selectively-activatible sheet material for dispensing and dispersing a substance onto a target surface. The sheet material comprises a three-dimensional sheet of material having a first side and a second side. The said first side has a plurality of hollow protrusions extending outwardly therefrom and separated from one another by valleys, while the second side has a plurality of depressions corresponding with the hollow protrusions. A substance adheres to and partially fills a location protected from external contact comprising the valleys and/or the depressions. The sheet material may be selectively activated by deforming the hollow protrusions to deliver the substance to a target surface, the substance having an effective viscosity upon activation which permits the substance to be liberated from its protected location and dispensed onto the target surface. Suitable substances include cleansing agents, medicinal agents, emollients, lubricants, colorants, preservatives, protectants, condiments, adhesives, fragrances, anti-perspirants, deodorants, and combinations thereof. The present invention also includes such materials having two or more substances of diverse composition, and substances which undergo a decrease in effective viscosity upon activation (such as shear-thinning substances) are particularly preferred. Additional layers of porous material may also be employed on the opposite side of the substance from the sheet material such that the substance may be dispensed through the porous material. Porous materials may provide additional beneficial interaction with the substance, including enhanced distribution and dispersal.

The present invention relates three-dimensional sheet materials which resist nesting of superimposed layers into one another. More particularly, the present invention provides a three-dimensional, nesting-resistant sheet material having a first side and a second side. The first side comprises at least one region having a plurality of spaced three-dimensional protrusions extending outwardly from the first side which are preferably unitarily formed from the sheet material. To provide the nesting-resistant advantages of the present invention, the protrusions form an amorphous pattern of a plurality of different two-dimensional geometrical shapes. Preferably, the second side comprises a plurality of spaced, three-dimensional hollow depressions corresponding to the protrusions, such that the protrusions are hollow. Of particular interest for certain applications, such as a carrier for an adhesive, the protrusions are separated by an interconnected network of three-dimensional spaces between adjacent protrusions. The three-dimensional, nesting-resistant sheet materials are preferably manufactured in accordance with the present invention utilizing a three-dimensional forming structure comprising an amorphous pattern of spaced three-dimensional recesses separated by interconnected lands. The recesses form an amorphous two-dimensional pattern of interlocking two-dimensional geometrical shapes. The amorphous pattern of interlocking shapes is preferably derived from a constrained Voronoi tessellation of 2-space in accordance with the present invention, wherein the tessellation is constrained by a constraint factor which controls the range of permissible center-to-center spacing of the interlocking shapes. To manufacture the three-dimensional, nesting-resistant sheet materials in accordance with the present invention, a sheet of deformable material is introduced onto the forming structure and permanently deformed into compliance with the forming structure. If desired, the interconnected lands of the forming structure may be coated with a substance before the sheet of deformable material is introduced onto the forming structure.
