摘要:
The present invention relates to a tampon suitable for feminine hygiene and/or medical purposes having a longitudinal body provided with a dome-shaped insertion end and a withdrawal end, from which withdrawal end a withdrawal cord extends, whereby the tampon essentially consists of compressed absorbent fibrous material and has an outer circumferential surface which is at least partially provided with longitudinal grooves that are separated from each other by longitudinal ribs. The tampon is in particular characterised in that the path of said grooves and said ribs in the longitudinal direction of said tampon corresponds to a continuous curved line that has only one point of inflection defining one convex part and one concave part, and that preferably does not show a maximum and/or a minimum.

The purpose of the invention is to create a process of manufacturing a tampon (1) of the previously described art, which could be manufactured in mass production by means of existing technology and equipment presently known to those skilled in the art, and into which either a solid or liquid therapeutic means (2) could be introduced during performing of commonly known steps in said method of manufacturing. The invention provides that upon radial compression due to forming ribs and grooves, namely prior to axial compression due to forming said tip (13) of a tampon (1), the last is furnished with a blind hole (14), which extends coaxially with central longitudinal axis (100) of said tampon (1), upon which each therapeutic means (2) is introduced into said hole (14), which is then followed by performing a further step, namely compression in axial direction (100) due to forming a tip (13) of the tampon (1).

The present invention relates to an intravaginal tampon for feminine hygiene. In particular, it relates to methods for producing such a tampon having relatively deep, penetrating grooves in which adjacent penetrating jaws pass through the same tampon press space during manufacture and to an apparatus useful in making such a tampon as well as the tampons made therewith.

Regarding a tampon, which can be manufactured of the same raw materials, by means of the same machines and by means of essentially the same steps like the commercially attractive known tampons, it is the purpose of the invention to improve its capability of retaining the fluid when inserted into each vaginal cavity and to prevent migration of fluid in both directions, namely from the vaginal cavity and also from outside into said vaginal cavity, wherein simultaneously also the interconnection between the fibers and the withdrawal string should be improved, and disinfecting effect should be achieved. To this aim, such tampon is furnished with a barrier (4), which is foreseen adjacent to the rear end portion (3) of the tampon, which prevents migration of fluid along the tampon, namely in one or another direction along the longitudinal geometric axis (0) of the tampon, wherein said barrier (4) is formed by means of a highly compressed area on the fibrous band (1), which is located at a pre-determined distance (L) apart from the rear end portion (3) of the tampon, wherein the density of fibers within said area is at least three times greater than in residual portions of the fibrous band (1) i.e. of the tampon and amounts at least approximately 2 g/cm3. The invention also includes a process for manufacturing such tampon.

A method of integrating a tampon includes providing an absorbent blank having a longitudinal centerline and compressing the absorbent blank in a direction perpendicular to the longitudinal centerline to form a pledget having a compressed diameter. The method also includes penetrating the pledget in the perpendicular direction to a compressed depth of at least 20% of the compressed diameter to form a discrete indentation.

The present invention relates to an intravaginal tampon for feminine hygiene includes a generally cylindrical absorbent pledget and a withdrawal element operatively connected to the generally cylindrical pledget proximate to the withdrawal end thereof. The absorbent pledget includes a mass of fibers compressed into a self sustaining shape and a sheet-like fluid-permeable cover substantially enclosing the mass of fibers. The absorbent pledget has formed thereon or therein at least one continuous groove form comprising a plurality of substantially longitudinal groove segments linked only to form a turn located alternatively proximate the insertion end and withdrawal end and wherein the continuous groove form extends around at least 180° about the circumference of the generally cylindrical absorbent pledget.

The absorbent pledget includes a mass of fibers compressed into a self sustaining shape and a sheet-like fluid-permeable cover substantially enclosing the mass of fibers. The absorbent pledget has formed thereon or therein a plurality of detached groove forms. At least two of said detached groove forms each has a length, measured along the groove, that is at least 150% of the length of the pledget; each has a major axis having a generally longitudinal orientation; and each has a turn proximate to at least one of the insertion end and the withdrawal end.
