Problems solved by technology

[0015] While the prior art adequately describes examples of hygienic protection articles that trap bodily fluids in the vagina, these examples do not overcome the problem of premature failure, often due to side leakage, common with internal hygienic protection articles
Many solutions to this problem involve adding elements before compressing the tampon wadding, so that the tampon expands uncontrollably when exposed to body fluids

Embodiment Construction

[0028] As used in this specification and claims, the term "body fluids" and variations thereof mean bodily excretions, especially liquids produced, secreted, emitted and / or expelled from the human body.

[0029] As used in the specification and claims, the term "fluid" and variations thereof refer to liquids, especially bodily fluids.

[0030] As used in the specification and claims, the term "fluid communication" and variations thereof refer to elements arranged or configured to allow liquid to flow between them. Fluid movement can be through interfiber capillary movement, intrafiber capillary movement, osmotic pressure, interplate capillary action, mechanical channels, etc.

[0031] As used herein, the term liquid storage element refers to any absorbent medium that forms the absorbent portion of an intravaginal device. In tampons, the fluid storage element may also be referred to as an absorbent core. The fluid storage element may be of a single density or have portions of...

Abstract

Controlled expansion of an intravaginal device can be achieved by selectively attaching either a primary or secondary cover to the primary absorbent device having a fluid storage element, we can determine that certain portions of the tampon will expand while other portions will be restricted to substantially the compressed structure. The primary cover can be attached to the primary absorbent device either before or after the absorbent device is compressed into final tampon form. The compression may be in the axial or radial direction or a combination of both directions. The secondary cover, if used, can be attached after the tampon pledget has been compressed into the final tampon form.
