Tampons have been used by women for many years to contain and absorb menstrual fluid during menses, to avoid soiling undergarments, outer clothing, bedding, etc. The typical currently marketed tampon is formed of an absorbent structure that may include absorbent material(s) such as rayon and cotton. The structure is typically formed and compressed into a cylindrical shape about the size of a small finger, having a forward/insertion end and a rearward end, and configured to be easily inserted into suitable position in the vaginal cavity and then to expand therewithin as it is contacted by and absorbs menstrual fluid, and swells with the absorbed fluid. Typically, a tampon will include a securely attached withdrawal cord extending from its rearward end, of a length sufficient to extend down the vaginal canal and outside the vagina during and after insertion of the tampon into suitable position. After a desired length of time following insertion the user may pull the cord to withdraw and remove the tampon.
Some users prefer tampons that are unaccompanied by applicators, preferring to insert a tampon using a finger to directly (“digitally”) contact and manipulate the tampon into suitable position within the vaginal cavity.
Other users, however, prefer a tampon that is provided with an applicator assembly that houses the new tampon prior to use, and facilitates insertion without the need to insert a finger into the vaginal canal. The typical applicator assembly includes a hollow barrel portion, often of a substantially cylindrical shape and having a forward end and a rearward end, within which the new tampon is contained. The applicator assembly also typically includes an ejection plunger that is disposed in contact with the rearward end of the tampon inside the barrel portion, and extends rearwardly from the rearward end of the barrel portion, and is configured to slide coaxially into the rearward end of the barrel portion and thereby provide a mechanism by which the user can push the tampon out the forward end of the barrel portion. The forward end of the barrel portion may be rounded or tapered to a gently rounded but openable tip to facilitate insertion. An openable configuration may be formed of a group of radially-arranged flexible petals that are rounded and curved inwardly at their distal ends toward the longitudinal axis of the applicator assembly, to close off the forward end and contain the new tampon, but flex radially outwardly under contact and forward pressure by the tampon, to open and allow the tampon to be urged forward and out of the forward end of the barrel portion when the ejection plunger is pushed by the user.
Applicator assemblies and their component parts may be formed of various materials and have a variety of design features, to enhance the user experience and facilitate cost-effective manufacture. Any improvements to features that further either of both of these objectives may provide the manufacturer/seller of tampons with applicator assemblies a competitive advantage.
As used herein “applicator assembly” refers to a device or implement that houses, and facilitates the insertion and placement of, a tampon or other device into an external orifice, such as the vagina. Non-limiting specific examples of such include any known applicator assembly that may be used for insertion of a tampon, such as telescoping tube and plunger assemblies.
“Substantially parallel,” with respect to two coplanar lines of direction, describes lines of direction that are precisely parallel (never intersect), and lines of direction that intersect and thereby deviate from precisely parallel, by no more than 10 degrees.
“Substantially perpendicular,” with respect to two coplanar lines of direction, describes lines of direction that are precisely perpendicular (intersect at an angle of 90 degrees), and lines of direction that deviate from precisely perpendicular by no more than 10 degrees (i.e., intersect at an angle from 80 degrees to 100 degrees).
As used herein, “substantially cylindrical” refers to and includes the outer shape of a cylinder, but also includes shapes such as slightly oblate or slightly flattened cylinders, slightly curved cylinders, and shapes which have diameters and/or cross-sectional areas that vary slightly along their lengths, wherein minor deviation from a precise cylindrical shape does not compromise product manufacturability, function or utility.
The “longitudinal axis” of a tampon, or of a barrel portion of an applicator assembly, is the line along the normal direction of insertion of the tampon and applicator by a user, through the geometric center of a cross section profile of the tampon or barrel portion, where the cross section lies along a plane perpendicular to the normal primary direction of insertion. The longitudinal axis of an example of the barrel portion of an applicator assembly is illustrated in
“Lateral” with respect to a tampon or applicator assembly refers to a direction perpendicular to its longitudinal axis. “Width” refers to a dimension measured along a direction perpendicular to the longitudinal axis.
“Longitudinal” with respect to a tampon or applicator assembly refers to a direction parallel to its longitudinal axis. “Length” refers to a dimension measured along a direction parallel to the longitudinal axis.
“Axial” movement of an element means movement along the longitudinal axis of an element. An “axial” direction is parallel to the longitudinal direction.
“Coaxial” refers to the movement of an ejection plunger within a barrel portion of an applicator assembly, whereby the plunger moves within the barrel portion and substantially along and/or parallel to its longitudinal axis.
“Vaginal cavity” refers to the internal body cavity of a human female, extending between the introitus of the vagina (sometimes referred to as the opening or sphincter of the vagina) and the cervix.
Typically, a tampon is manufactured of one or more absorbent materials, which have been assembled, cut, shaped and compressed in one or both of the lateral direction and the axial direction, in order to provide a body of a size and stability of form when dry to allow for neat insertion into a user's vaginal cavity. Components, assembly methods, and precompression configurations and shapes may vary among manufacturers and/or manufacturing processes. A new tampon has a forward (insertion) end and a rearward (withdrawal) end. When housed in an applicator assembly, the forward end is proximate the forward (insertion) end of the barrel portion of the applicator assembly, proximate the petals (when included) of the barrel portion. Tampons intended for placement in the vaginal cavity to absorb menstrual fluid during menses often have a substantially cylindrical compressed shape prior to application. Preferably, a tampon will substantially retain its compressed shape and size as long as it is kept dry, prior to insertion and use. The pre-application shape and size need not persist following insertion and during use. Tampons typically expand in size and change shape in varying ways during use, as they are contacted by and absorb fluid.
Tampons also may be manufactured and formed to have other shapes and forms, as described in, for example, U.S. Pat. Nos. 6,824,536; 6,932,805; 8,597,267; 8,684,987; 8,216,202; 6,953,456; 6,554,814; 7,549,982; 6,939,340, and 8,029,485.
The tampon may be a non-layered, uniform structure, or it may be a laminar structure comprised of integral or discrete layers, or the tampon may have a folded structure, or it may be rolled, or any other suitable structure known in the art. Generally, it may be preferred that the tampon have a certain minimal rigidity when new and dry, to facilitate ejection from an applicator assembly and/or insertion, by pushing on the rearward end.
The tampon may be constructed from a variety of liquid-absorbing materials commonly used in absorbent articles, such as, for example, rayon, cotton, or comminuted wood pulp (which is generally referred to as airfelt). Examples of other suitable absorbent materials include creped cellulose wadding; formations including meltblown filaments spun from polymeric resin, including coformed formations; chemically stiffened, modified or cross-linked cellulosic fibers; synthetic fibers such as crimped polyester fibers; peat moss; absorbent foams; tissue including tissue wraps and tissue laminates; or any other suitably absorbent material or combination or blend of absorbent materials. Preferred absorbent materials include cotton and rayon (including tri-lobal and conventional rayon fibers, and needle punched rayon). Suitable types of rayon may include GALAXY rayon (a tri-lobal rayon fiber structure) available as from Kelheim Fibres GmbH of Kelheim, Germany, and TENCEL rayon (a round fiber rayon) available from Lenzing AG, Lenzing, Austria. Suitable cotton material includes, long fiber cotton, short fiber cotton, cotton linters, T-fiber cotton, card strips, and comber cotton. Additionally, superabsorbent materials, such as superabsorbent polymers or absorbent gelling materials in particle or fiber form may be incorporated into the tampon.
The absorbent material(s) of the tampon may be surrounded by an overwrap. The overwrap is preferably a liquid permeable material. Such materials may include knitted, woven or nonwoven fabrics of rayon, cotton, fibers spun from polymeric resins, including bicomponent fibers, or any other suitable natural or synthetic fibers known in the art. Rayon, polyethylene, polypropylene and blends of these are particularly suited for use as overwrap material. Synthetic fibers may include fibers spun or formed of polyester, polyolefin, nylon, polypropylene, polyethylene, polyacrylic, cellulose acetate, or combinations of these, such as bicomponent fibers. Natural fibers or semi-synthetic fibers may include fibers of cotton or rayon. In general, cotton and/or rayon fibers may be preferred for inclusion because they provide ready absorption and fluid wicking. Synthetic (polymer-based) fibers may also be preferred for inclusion for their surface characteristics and properties to balance the capillarity of more absorbent materials included, and enable the tampon to more readily slip against moist tissue, resulting in easier and more comfortable tampon insertion and removal. The overwrap may be adapted or formed to extend rearwardly beyond the rearward end of the assembly of absorbent material(s) to form a skirt portion, as described in U.S. Pat. No. 6,840,927, for example. The overwrap may be configured to extend from about 2 mm to about 30 mm beyond the rearward end of the assembly of absorbent material(s).
The tampon may include a withdrawal cord, which may be attached to or along any portion of the tampon. This may be any type of withdrawal cord known in the art, for example a generally braided (or twisted) withdrawal cord. A conventional type of withdrawal cord (in terms of thickness, material composition, etc.) may be periodically braided with a thicker slub of fibrous material, which acts as a wicking member, to form a structure to be connected to the remaining of the tampon. In such an embodiment, the portion of the cord, which will act as the withdrawal cord, may be treated to make it non-absorbent or even hydrophobic. It may also be a withdrawal cord as described in commonly assigned and co-pending U.S. application Ser. No. 09/309,467.
The tampon may contain any additional functional ingredients, such as antimicrobial agents, lubricants, antioxidants, pH modifiers, etc., as known in the art.
It may be preferred in some circumstances that the tampon may comprise a chevron-shaped (laminar) pad, prior to compression into a substantially cylindrical form. This pad may be formed to have a lateral width and a longitudinal length wherein the width is greater than the length. The pad may include at least three layers of absorbent material, including an uppermost layer, a lowermost layer, and at least one intermediate layer positioned between the uppermost layer and lowermost layer. Each of the uppermost layer and the lowermost layer may be formed primarily of rayon, and the at least one intermediate layer may be formed primarily of cotton.
Applicator Assembly
A tampon may be provided new within an applicator assembly, configured to contain the tampon until use, and then to facilitate insertion of the tampon without the need to insert a finger into the vaginal cavity to push the tampon into position. An applicator assembly having a barrel and plunger arrangement may be preferred. Barrel and plunger portions may be formed of molded polymer resin, paper, or other suitable material, or a combination thereof. It may be desirable in some circumstances that one or more components of the assembly be translucent or transparent to allow the user to view the tampon or a feature thereof within the assembly, for example, to determine whether the assembly contains a tampon (i.e., has not been used), or to observe features of the tampon. In some circumstances it may be desired that the material(s) forming the applicator be tinted or pigmented to impart a non-white color for esthetic purposes and/or to reduce visibility of menstrual fluid that may be deposited thereon following use. In some circumstances it may be desired that one or more components of the applicator assembly be substantially opacified, or opacified and tinted or pigmented.
The applicator assembly manufactured so as to be flushable as described in U.S. Pat. No. 6,730,057. The applicator assembly may be corrugated as described in U.S. Pat. No. 7,066,870. The applicator assembly may be provided with a gripping portion as described in U.S. Pat. Nos. 8,303,558; 7,081,110; 8,449,491, or 8,075,512. The applicator assembly may be provided with an absorbency indicator as described in U.S. Pat. No. 7,166,101.
The applicator assembly may be provided with a cap and/or insertion tip portion that allows for a smooth and safe insertion of the assembly. A rupturable cap may be provided as described in U.S. Pat. No. 6,610,025, that will protect the tampon from contamination prior to use, but will rupture and allow the tampon to be pushed forward and out of the applicator assembly when the user desires to do so. The cap be formed of or include flexible or movable petals as described in U.S. Pat. No. 6,652,477.
Referring now to
Barrel portion 21 may include an approximately or substantially tubular and hollow section which may also include a substantially cylindrical outer shape, have a forward end 23 and a rearward extent 24 and may be sized and proportioned to snugly contain a compressed tampon 10, while serving as a vehicle for facilitating comfortable delivery of the tampon to a suitable location within the vaginal cavity. In some examples barrel portion 21 may have a lateral cross section profile that is substantially circular; in other examples it may have a lateral cross section outer profile that is oval-shaped, ovoid-shaped, stadium-shaped or elliptical. Barrel portion 21 may have a forward/insertion end portion formed by a group of radially-arranged, flexible petals 22 defined by slots 22a therebetween as suggested in the figures. Petals 22 may be shaped and rounded radially inwardly as they approach the forward end 23, as suggested in the figures, to neatly form a smoothly tapering, rounded forward/insertion end portion/tip to facilitate easy and comfortable insertion. In some examples petals 22 may be integral extensions of the barrel portion 21, molded or otherwise heat-formed with a rounded taper as suggested in the figures.
Gripping portion 25 may have a forward portion 26, an intermediate portion 27, a rearward portion 28 and a rearward edge 29. As suggested in
Textural or topographic features on the surface may be both functional, for gripping slip resistance, and decorative, for esthetic appeal. Gripping portion 25 may be integrally molded or formed with barrel portion 21, or may be separately formed and then joined to barrel portion 21 via fusion/welding, thermal bonding, adhesive bonding, chemical bonding or other suitable bonding mechanism, or may be joined to the barrel portion via cooperating, interlocking physical/mechanical features. For purposes of efficient manufacture and structural integrity, it may be preferred that gripping portion 25 be integrally formed with/joined to barrel portion 21. Barrel portion 21 may be formed of any suitable material having suitable surface properties that provide for substantial non-absorption of body fluids (i.e., during the brief time of insertion and withdrawal in normal use) and low friction against moist tissue, to provide for ease and comfort of insertion and withdrawal. In some examples barrel portion 21 may be formed of a cardboard or paperboard tube, having an outer coating (e.g., of a wax or polymer) to provide for non-absorption and low friction. In other examples barrel portion 21 may be formed of a polymeric resin. In more particular examples barrel portion 21 may be formed of injection-molded polymeric resin predominately constituted by polyethylene, which has suitable low surface friction characteristics. In particular examples barrel portion 21 and gripping portion 25 may be integrally injection molded together.
Preferably, the majority of the outside surface area of the barrel portion 21 is provided with a smooth and/or glossy surface finish, to provide for low friction with tissues during use. In contrast, the gripping portion may be provided with a matte (or rougher) surface finish and/or any combination of the above-described features for enhancing gripping slip resistance.
To further enhance rapid visual and/or tactile identifiability of the gripping portion, the gripping portion and the barrel portion may be provided with visibly differing/contrasting colors; visibly differing levels of opacity/transparency/translucency; visibly/tactilely differing surface finishes, visibly/tactilely differing/contrasting surface textural features, tactilely differing/contrasting structural stiffness (e.g., gripping portion 25 is formed with thicker walls relative the barrel portion walls, resulting in a relatively, stiffer gripping portion structure that may be tactilely perceived), or any combination thereof. Additionally, or in combination, the respective barrel and gripping portions 21, 25 may be formed of or include respectively differing component materials or formulations thereof, that impart any of the visibly and/or tactilely perceivable differences listed in the preceding sentence.
Referring to
In some examples, the ejection plunger 17 may include two coaxially-arranged sub-portions (not shown) wherein one sub-portion may slide coaxially within the other in telescope fashion, as described and depicted in US 2015/0060317. Such a configuration for the ejection plunger may be included to provide the advantages described in the cited reference.
The barrel portion 21 and/or gripping portion 25 may be provided with one or more internal plunger guides 30, to provide a relatively close internal tolerance between the ejection plunger 17 and the barrel and/or gripping portions 21, 25, at least two differing longitudinal positions within the barrel portion and/or gripping portion. Plunger guides 30 may be provided and suitably configured and sized to provide clearances that ensure that the plunger may effectively freely slide longitudinally therewithin, but be guided substantially linearly/coaxially through the gripping and barrel portions to efficiently eject the tampon 10 from barrel portion 21 during application. The ejection plunger 17 may be provided with one or more retainer structures 19 that cooperate with internal features of the barrel portion and/or the gripping portion (such as plunger guides 30) to prevent the plunger 17 from sliding out and away from the rear of the gripping portion. The plunger 17 also may be provided with one or more latching/detent structures 18 that cooperate with internal features of the barrel portion and/or the gripping portion (such as plunger guides 17) to latch the plunger 17 into a forward position following substantial ejection of the tampon 10, indicating that the applicator assembly has been used, and retaining the applicator (including the ejection plunger) in a more compact form for carrying and disposal following its use (as appears in
Comparing
As may be appreciated from
This difference in lateral dimensions between rotational orientations of the gripping portion 25 may enhance its slip resistance and/or ergonomic feel. It also may serve to provide the user with a tactile indication of rotational orientation of the applicator assembly, which may be useful in examples in which the tampon within the barrel portion has directionality or differing shape or expansion features according to the tampon's rotational orientation. For example, referring to
Additionally, gripping portion 25 may have an effectively greater length dimension along rearward edge 29 at one pair of opposing portions, and an effectively lesser length dimension along rearward edge 29 at a second, differing pair of opposing portions. For example, referring to FIGS. 3A, 3B and 4A, one pair of opposing portions 29L of the rear edge 29 of the gripping portion may extend rearward from the forward tip of the applicator to a relatively greater length L1, and a second pair of opposing portions 29S of rear edge 29 of gripping portion 25 may extend rearward from the forward tip of the applicator to a relatively lesser length L2. In some examples, these respective pairs of opposing portions may be disposed approximately 90 degrees from each other about the longitudinal axis of the applicator assembly. This provides a relatively greater length of the gripping portion, extending to length L1, for the user to grip the gripping portion, while the dip or recess in the rear edge 29 extending to lesser length L2 enables the user to depress ejection plunger 17 into the applicator assembly in an axial direction (marked by the large arrows in
