Definitions

  • the invention pertains to a tampon having an absorption body having generally elongate shape and having a withdrawal end, and comprising a withdrawal string attached to the absorption body and extending from the withdrawal end.
  • Menstrual tampons for intra-vaginal use have long been known and used. As tampons are worn internally, they are considered to be discrete and generally very comfortable to wear, lacking the occluding plastic backing of external protection devices such as sanitary napkins. However, as the tampon absorbs moisture, it will expand and press against the vaginal wall. Moreover, the tampon will absorb menstrual discharge as well as humidity from the mucous membranes on the vaginal wall, thus drying out the mucous membranes. Both the expansion of the tampon and the absorption from the vaginal wall result in increased friction between the tampon and the vaginal wall.
  • Lubricating agents are often hydrophobic materials that may migrate into the absorbent material and restrict fluid flow into the absorbent body of the tampon.
  • vaginal tampon that can be easily and comfortably removed even when only partially saturated by menstrual fluid.
  • a tampon which comprises a withdrawal aid.
  • the withdrawal aid is provided in the form of an additional outer cover that is attached to and extending from the insertion end of the tampon and is arranged to be movable between a first position in which the withdrawal aid at least partly covers the absorption body and a second position in which the withdrawal aid extends away from the absorption body.
  • the tampon of WO 2005/063161 facilitates withdrawal by allowing the outer cover to invert upon withdrawal.
  • the outer cover is loosely applied on the outside of the tampon and the gap between the outer cover and the surface of the tampon constitutes a barrier to direct and rapid liquid flow into the tampon.
  • a tampon comprising an absorption body having a generally elongate shape and having a withdrawal end and comprising a withdrawal string attached to the absorption body and extending form the withdrawal end.
  • the tampon is primarily distinguished in that the absorption body has a tubular shape at least in a part of the absorption body located at an end thereof and being adapted to be foldable onto itself for bringing the tampon into a folded state before insertion of the tampon, the tampon in the folded state having an inner body portion and an outer body portion and a fold body portion, which defines an insertion end, wherein the withdrawal string extends from the inner body portion.
  • the fold body portion is defined by the fold in the tubular body in between the inner and the outer body portion as the tubular absorption body is folded over itself.
  • the withdrawal string extends from the inner body portion at the withdrawal end of the tampon in order not to hamper unfolding of the tampon upon withdrawal after use.
  • the at least partially tubular absorption body of the tampon has a first, non-folded state and a second folded state.
  • the tampon is preferably provided to the user in a folded and compressed state.
  • a folded and compressed tampon will have the visual appearance of a conventional tampon, the folded configuration not becoming apparent to the user until the tampon is being removed from the vagina after it has been used.
  • the absorption body may be of tubular configuration over its full length extension implying that it has a hollow central portion.
  • only the portions forming the outer body portion and the fold body portion when the absorption body is in the second, folded state have the tubular configuration.
  • a tubular portion of the absorption body is arranged to be turned inside out and to be folded over the inner body portion.
  • the inner and outer body portions need not have the same length extension. Accordingly, the inner body portion may have greater length than the outer body portion implying that the inner body portion will protrude somewhat from the outer body portion at the withdrawal end of the tampon. Alternatively, the outer body portion may have greater length than the inner body portion so that the inner body portion terminates inside the outer body portion at a distance from the withdrawal end.
  • Suitable materials for the absorption body include absorbent fibres such as viscose fibres, cotton fibres and cellulose fluff pulp fibres.
  • the absorption body may also include non-absorbent fibres such as polymer fibres which may be mono-component fibres, bi-component fibres or multi-component fibres.
  • Particularly useful polymers are thermoplastic polymers such as polyolefins and polyesters which can be used as binders for the absorption body.
  • Further materials that may be used either alone or in combination with fibrous structures are open-celled absorbent and non-absorbent hydrophilic foams.
  • the absorption body may also include superabsorbent materials, such as up to 10% superabsorbent.
  • the absorbent material in the outer body portion and the fold body portion may be bonded into a coherent, fibrous structure having tubular cross-section.
  • Further means of increasing the coherency of the absorption body is by using staple length fibres which are formed into a fibrous web by carding. Fibrous webs may be formed by carding, meltblowing or meltspinning and may be subsequently bonded by application of heat and/or mechanical bonding such by hydroentangling or needling.
  • Further means of creating coherent absorbent tampon bodies is by knitting or crocheting.
  • the tubular part of the tampon body may be elastically extensible particularly in the cross-sectional direction.
  • Elasticity may be achieved by using elastic fibres, elastic strands, elastic binders, etc. and may contribute to facilitate folding of the tampon without creating cracks or in other ways damaging the tampon material.
  • the insertion end of a tampon is the part of the tampon, including the tip of the tampon that is fist introduced into the vagina.
  • the withdrawal end of the tampon is the leading end when the tampon is withdrawn after use.
  • the outer body portion will be in contact with the mucous membranes on the user's vaginal wall.
  • the tubular absorption body will be gradually folded back to resume its original non-folded length.
  • the outer body portion is held substantially still in relation to the vaginal wall while the inner body portion moves in relation to the vaginal wall and the outer body portion.
  • the tubular absorption body is caused to slidingly unfold as the tampon is being pulled out. In this manner, removal of the tampon is greatly facilitated and chafing and abrasion of the mucous membranes is reduced.
  • the at least partially tubular absorption body is fully unfolded it has considerably smaller diameter than it had in the folded configuration and is easy to pull away, without causing any pain or other discomfort.
  • the tampon according to the invention has preferably essentially cylindrical shape and can be provided with a liquid permeable cover in order to minimise linting from the absorption body.
  • the cover is preferably a material that exhibits low friction against itself, to facilitate folding and unfolding of the partially tubular tampon body.
  • the cover material may be arranged to cover all or part of the length of the unfolded tampon body. When the tampon is in the folded state, the cover material will be inside the tampon between the inner and the outer body portions and will have abutting surfaces that slide against each other upon movement of the body portions such as when the tampon is being unfolded upon withdrawal.
  • a cover may also be applied to the outer tampon surface when the tampon is in the folded state.
  • Outer tampon covers are conventional in the art and are usually low-friction nonwoven materials. It has also been suggested to use other liquid permeable materials such as nettings, open-celled foams or perforated plastic films to cover the outer surface of a tampon.
  • Suitable cover materials may include nonwovens, nettings and perforated plastic films.
  • the cover material may be hydrophilic or hydrophobic.
  • a hydrophilic cover material may be made from a non-absorbent polymer material provided with a hydrophilic finish. It is also possible to use cover materials that are inherently hydrophilic and may be capable of absorbing a small amount of liquid. It is also within the scope of the invention to arrange a cover material on the outside of the completely folded tampon body so that the surface of the tampon that will be in contact with the vaginal wall when the tampon is being used is covered by the cover material. A cover material that will be in prolonged contact with mucous membranes may be provided with some degree of absorbency.
  • the inner and outer cover materials may be different from each other and are preferably optimised with regard to their different functions in the tampon.
  • low friction materials and low friction additives include poly vinyl alcohol (PVA), lotion, oil, wax, hydrogels or hydrogelling materials, polysiloxane gels, low friction films, nettings and coatings etc.
  • PVA poly vinyl alcohol
  • the low friction material will be positioned between the inner body portion and the outer body portion. In this manner the inner and outer body portions can easily slide against each other and the folding and unfolding of the tubular absorption body may be made smoothly and without effort.
  • Different compression in the inner and outer body portions may be achieved by compaction of the inner body portion before the outer body portion is folded over the inner body portion.
  • the inner body portion comprises absorption material that is more susceptible to compaction than the material in the outer body portion
  • compaction of the tampon may be performed after the tampon has been folded and still result in the inner body portion being denser than the outer body portion in the finished, folded and compressed tampon.
  • a tampon having different materials and different densities in inner and outer portions thereof is disclosed in WO 2007/001216. The materials disclosed in WO 2007/001216 may be used also in the tampon according to the present invention.
  • a tampon with an inner body portion being more compressed or at least denser than the outer body portion can be provided with the requisite rigidity to enable digital insertion without compromising softness and liquid acquisition properties in the outer body portion.
  • the enhanced rigidity in the inner portion makes the tampon easy to grip and insert into the vaginal cavity without bunching or bending.
  • the less dense outer body portion may provide the principal absorption capacity and is preferably resilient so that it will expand into contact with the vaginal wall and prevent leakage past the tampon.
  • the lower density in the outer body portion ensures rapid initial absorption of menses and makes the outer body portion of the tampon soft and comfortable both during insertion and use.
  • a soft, relatively flexible, low density outer body portion will readily unfold when the tampon is being withdrawn after use.
  • the inner body portion, the fold body portion and the outer body portion may comprise a material that is continuous in the length direction of the tampon.

  • At least one of the inner body portion, the fold body portion and the outer body portion may comprise a material that is different from the material in at least one of the other body portions.
  • One or more of the body portions may be formed from a layered structure with different materials in concentrically arranged layers. It is conceivable to make all three body portions of material having different properties, such as different densities or different compositions or layers.
  • the tampon body may comprise different additional materials in the different portions of the tampon body.
  • the inner body portion may have a solid rod shape, with only the fold body portion and the outer body portion having a tubular shape.

However, the tubular structure may be collapsed so that the inner cavity has been reduced or eliminated.
  • the outer circumferential surface of the least partially tubular absorption body may comprise a low friction material or alternatively a low friction additive, allowing easy folding and unfolding of the tampon. Due to the low friction material respectively low friction additives the contact surfaces between the inner and outer body portion can slide against each other in a smooth way. Thereby easy folding and unfolding of the at least partially tubular absorption body is ascertained. When the tampon is being pulled out after use, the tubular absorption body will simultaneously be folded back and resume its original length, due to the low friction between the inner and outer body portions.
  • the outer body portion As the tampon is being pulled out the outer body portion is held substantially still in relation to the vaginal wall, and the inner body portion shows a sliding motion in relation to the vaginal wall and to the outer body portion, causing the tubular absorption body to completely unfold.

  • Any material such as a low-friction cover, a lubricant or an additive placed on the surface of the non-folded at least partially tubular absorption body may potentially restrict fluid transport into and back out from the absorption body.
  • the outer body portion preferably has an outer surface that allows rapid fluid uptake and that acts as an initial reservoir for absorbed liquid. The absorbed liquid will subsequently be drained from the outer body portion into the inner preferably denser body portion.
