Description:
FIELD OF INVENTION  
       [0001]     This invention relates to a tampon applicator, particularly, to a tampon applicator providing proper placement of a tampon within the vaginal cavity.  
       BACKGROUND OF THE INVENTION  
       [0002]     Tampon applicators have been used for inserting a tampon into a vaginal cavity to prevent leakage of menstrual fluids or other fluids. In the field of tampon applicators, “push” type tampon applicators are well known. These applicators generally comprise, in a simple form, a pair of coaxial hollow cylinders or tubes. The larger outer tube serves as a vaginal insertion tube and comprises a tampon. The smaller inner tube serves as a plunger which ejects the tampon from the outer tube.  
         [0003]     It has been recognized that tampon applicators of the type described above have certain deficiencies which can be readily apparent to many users of such devices. In general, the position of the tampon within the vaginal cavity can directly impact the tampon&#39;s efficiency of reducing and/or eliminating leakage. For example, conventional “push” type applicators can place a tampon too high in the vaginal cavity. The higher the tampon is placed, the greater the chance of leakage due to the tampon being above the major path of fluid flow. In other words, menstrual fluids can pass by the tampon without being absorbed.  
         [0004]     In addition, if the position of the tampon is too high in the vaginal cavity, the tampon can extend into portions of the vaginal cavity, where, for reasons of the size and mechanical properties of the tampon, the tampon can be negatively affected by the vaginal organs, further reducing the tampon coverage of menses flow in the vaginal cavity. Moreover, current tampon applicators are designed to “push” the tampon out of the outer tube so that the tip of the tampon is substantially higher than the outer tube. This often causes the tampon to be deflected by the cervix, resulting in an off-centered position of the tampon, and, thus, in possible leakage from the vaginal cavity.  
         [0005]     Alternatively, a tampon can be placed too low in the vaginal cavity. When the tampon is placed too low in the vagina cavity, the too low position of the tampon can cause bodily discomfort to the wearer because of the pressure exerted from the sphincter muscles against the tampon. Also, if the tampon is placed too low, accidental expulsion of the tampon is a highly undesired risk.  
         [0006]     To solve the above problem of positioning the tampon, it would be beneficial to provide a tampon applicator which properly places the tampon low in the vaginal cavity.  
       SUMMARY OF THE INVENTION  
       [0007]     The present invention encompasses a tampon applicator for positioning of a tampon. The tampon applicator comprises a tampon, a tampon housing member, a cover member, and a tampon positioning member. The tampon is partially housed within the tampon housing member. The tampon extends beyond the tampon housing member. The cover member covers at least a portion of the tampon housing member. The tampon housing member is telescopically mounted within the cover member. The tampon positioning member positions the tampon within the tampon housing member. The tampon positioning member is disposed inside the tampon housing member and is co-axial with the tampon. The tampon positioning member can be fixedly joined to the cover member. Alternatively, the tampon positioning member can be fixedly joined to the tampon housing member.  
         [0008]     The present invention can also encompass a tampon applicator wherein the tampon housing member can be slideable over the tampon positioning member. In another embodiment, before expulsion of the tampon from the tampon applicator, the bottom end of the cover member can be positioned below the bottom end of the tampon housing member. In yet another embodiment, the tampon housing member can be joined to the cover member. Specifically, the exterior of the tampon housing member can be joined to the hollow interior of the cover member.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0016]     Section A will provide terms which will assist the reader in best understanding the features of the invention but not to introduce limitations in the terms inconsistent with the context in which they are used in this specification. These definitions are not intended to be limiting. Section B will discuss the tampon applicator of the present invention.  
         [0000]     A. Terms  
         [0017]     As used herein, the term “tampon” refers to any type of absorbent structure that can be inserted into the vaginal cavity or other body cavities for the absorption of fluid therefrom or for the delivery of active materials, such as medicaments or moisture. A tampon can be straight or non-linear in shape, such as curved along the longitudinal axis.  
         [0018]     Generally, there are two types of tampons. The first type of tampon is a self-sustaining tampon. Tampons are generally “self-sustaining” in that they will tend to retain their general shape and size before use. A typical self-sustaining tampon is 35-60 mm long, the length measured from the top of the tampon to the base of the tampon along a longitudinal axis. The measurement to the base of the tampon does not include any overwrap, secondary absorbent member, or withdrawal cord which extends beyond the tampon&#39;s main absorbent material. A typical self-sustaining tampon is 5-20 mm wide corresponding to the largest cylindrical cross section. The width can vary along the length of the self-sustaining tampon.  
         [0019]     The second type of tampon is an easily “deformable, fluid-permeable bag tampon”. The deformable, fluid-permeable bag tampon consists of absorbent chips, spheres, or fibers such that the fluid permeable bag tampon is readily deformable with a force of less than about 3 psi. The tampon is substantially deformable at pressures of less than about 1 psi; resulting in the tampon spreading or being easily indented when the pressure is applied from a surface of about 0.15 mm diameter.  
         [0020]     As used herein, the terms “vaginal cavity,” “within the vagina,” and “vaginal canal” refer to the internal genitalia of the human female in the pudendal region of the body. The term “vaginal canal” is not intended to include the interlabial space including the floor of the vestibule. The externally visible genitalia generally are not included within the term “vaginal canal” as used herein.  
         [0021]     As used herein, the term “hymen ring” refers to the demarcation between the vagina and the external genitalia and is identified by the position of the hymen or residual tissue of the hymen.  
         [0022]     As used herein, the term “proper placement” refers to the vertical position of the tampon inside the vaginal cavity, wherein the base of the tampon (i.e., the main absorbent material) is positioned at least about 5 mm above the hymen ring and more preferably greater than about 10 mm above the hymen ring. The base of the tampon does not include any overwrap, secondary absorbent member, or withdrawal cord which extends beyond the tampon&#39;s main absorbent material.  
         [0023]     The term “fully expelled” refers to as the base of the tampon disengaged from the all portions of the tampon applicator when the tampon positioning member is at the proximal position. The base of the tampon does not include any overwrap, secondary absorbent member, or withdrawal cord which extends beyond the tampon&#39;s main absorbent material.  
         [0024]     The term “partially expelled,” as used herein, is meant that the base of the tampon partially retained within a portion of the applicator when the tampon positioning member is at a proximal position. The base of the tampon does not include any overwrap, secondary absorbent member, or withdrawal cord which extends beyond the tampon&#39;s main absorbent material.  
         [0025]     The terms “distal” and “proximal,” respectively designated P and D in  FIG. 1   b , herein respectively refer to directions away from and towards the body of the tampon wearer unless otherwise specified.  
         [0026]     The term “joined” or “attached” encompasses configurations in which an element is directly secured to another element by affixing the element directly to the other element; configurations in which the element is indirectly secured to the other element by affixing the element to intermediate member(s) which in turn are affixed to the other element; and configurations in which one element is integral with another element; i.e., one element is essentially part of the other element.  
         [0000]     B. Tampon Applicator of the Present Invention  
         [0027]     Referring to  FIG. 1   a , a tampon applicator  10  is shown which is designed to position tampon  11  to achieve proper placement in the vaginal cavity.  
         [0028]      FIG. 1   b  is an exploded view of  FIG. 1   a  of the tampon applicator  10  along a longitudinal axis  60 . The tampon applicator  10  is designed to provide a comfortable means of inserting a tampon  11  into a human&#39;s vagina. The tampon applicator  10  can be used with any type of tampon  11 . For example, the tampon  11  could be a self-sustaining tampon or a deformable, fluid-permeable bag tampon. Generally, the tampon applicator  10  includes a tampon  11 , a tampon housing member  12 , a cover member  18 , and a tampon positioning member  14 .  
         [0029]     A hollow interior  15  of the tampon housing member  12  can contain at least a portion of the tampon  11 . The tampon housing member  12  can be telescopically slideable within a hollow interior  19  of the cover member  18 .  
         [0030]     The cover member  18  covers at least a portion of the tampon housing member  12  and can be used to handle or grip the tampon applicator  10  during insertion into the vaginal cavity. The cover member  18  has a top end  20  and a bottom end  21  opposed to the top end  20 . The top end  20  is the most proximal end of the cover member  18  along the longitudinal axis  60 . The cover member  18  can have a guard  43  located at the top end  20  of the cover member  18  that pushes or “plows” tissue of a wearer away from a lapping position  40  (seen in  FIG. 2 ). The lapping position  40  (shown in  FIG. 2 ), which is located between the tampon housing member  12  and the top end  20  of the cover member  18 , minimizes the risk of pinching the body tissue of the tampon wearer.  
         [0031]     The tampon positioning member  14  positions the tampon  11  along the length of the tampon housing member  12  so that during expulsion of the tampon  11 , the tampon  11  will travel a pre-determined distance. The tampon positioning member  14  can be disposed within the hollow interior  15  of the tampon housing member  12 . The tampon positioning member  14  has a first end  22  and a second end  23  opposed to the first end  22 . The first end  22  of the tampon positioning member  14  can contact the tampon  11  during expulsion of the tampon  11  from the tampon housing member  12 . The second end  23  of the tampon positioning member  14  is the most distal end along the longitudinal axis  60 .  
         [0032]     To use the tampon applicator of the present invention, the user can insert the tampon applicator into the vaginal cavity by holding a gripping area  41  located in the end  21  of the cover member  18  with the wearer&#39;s thumb and index finger. Typically, a perimeter  42  of the grip region  41  can be of any shape. During insertion, as the tampon housing member  12  slides within the hollow interior  19  of the cover member  18 , the tampon  11  becomes more exposed within the vagina. Typically, the guard  43 , as noted above, is placed on the top end  20  of the cover member  18  to push or “plow” the body tissue away from the lapping position  40  (shown in  FIG. 2 ).  
         [0033]      FIG. 1   c  shows a cross-sectional view of the tampon applicator  10 . Specifically, the tampon  11 , the tampon housing member  12 , the cover member  18 , and the first end  22  of the tampon positioning member  14  are shown.  
         [0034]      FIG. 2  shows an alternative embodiment of the tampon applicator of the present invention. The tampon housing member  12  of tampon applicator  10 A comprises an accordion collapse zone  39  to house the tampon  11 .  
         [0035]      FIG. 3  shows an alternative embodiment of the tampon applicator of the present invention. Tampon applicator  10 B comprises a tampon positioning member in the form of a rod  27 . The rod  27  positions the tampon  11  along the length of the tampon applicator  10 B. The tampon  11  can rest on top of the rod  27 . Specifically, a base  13  of the tampon  11  can rest on top of the rod  27 . The base  13  of the tampon  11  is located adjacent a string  28 . The string  28  is attached to the tampon  11 . The string  28  can extend back through the tampon housing member  12 .  FIG. 4  shows another alternative embodiment of the tampon applicator of the present invention. Tampon applicator  10 C comprises a tampon positioning member in the form of projections  24 . The projections  24  can extend inward from the hollow interior  15  of the cover member  18 . The tampon  11  can rest on a first end  25  of the projections  24 . Alternatively, the projections  24  can be monolithically formed on the cover member  18 .  
         [0036]     In addition to delivering menstrual tampons into the vaginal cavity, it should be noted that the tampon applicator of the present invention can be used to deliver any other type of absorbent or nonabsorbent object to any suitable cavity. For example, the tampon applicator of the present invention could be used to insert incontinence inserts. An “incontinence insert,” as used herein refers to devices specifically designed, configured, and/or adapted for placement into a vagina in order to reduce the occurrence and/or severity of female urinary incontinence. While incontinence inserts are typically made of non-absorbent materials, at least partially absorbent materials may also be used. However, because there is no intent to absorb bodily fluids, and because the incontinence inserts are adapted and configured to provide structural support to the musculature and body tissues located near the urethra-vaginal myfascial area, incontinence inserts are readily distinguishable from catamenial tampons.  
         [0037]     Below will detail each component of the tampon applicator of the present invention.  
         [0038]     i. Tampon Housing Member  
         [0039]     Referring to  FIG. 1   b , the tampon housing member  12  houses or contains the tampon  11 . The tampon housing member  12  has the hollow interior  15 . The manufacturer of the tampon applicator  10  can vary the configuration of the tampon housing member  12  and the length of the tampon housing member  12 . The configuration of the tampon housing member  12  is preferably created to house or contain the tampon  11 . Furthermore, the shape or configuration of the tampon housing member  12  can vary as long as a portion of the tampon  11  is partially contained by the tampon housing member  12 . One skilled in the art can imagine other configurations of the tampon housing member  12 , for example, cylindrical or curved like a banana or any other suitable shape possible as long as any such shape would work effectively to house or partially contain the tampon  11 , properly aiding in the expulsion of the tampon  11  from the tampon applicator  10 , and comfortably inserting the tampon  11  into the vaginal cavity. Accordingly, the tampon housing member  12  can be of any suitable cross-sectional shape including, but not limited to, circular, oval, flattened circular, elliptical, and any combination thereof. The diameter of the tampon housing member  12  can be varied to accommodate different absorbency tampons. For example, higher absorbency tampons can have larger diameters resulting in the tampon housing member  12  having a larger diameter to house the higher absorbent tampon. In addition, the tampon housing member  12  can have varying diameters to conform to the profiled shape of the enclosed tampon  11 .  
         [0040]     The length of the tampon housing member  12  can also vary. The tampon housing member  12  should be of a sufficient length to house or contain at least a portion of the tampon  11  prior to insertion of the tampon applicator  10  into the vaginal cavity. The length of the tampon housing member  12  can be between from about 20 mm to about 89 mm. In one non-limiting example, the length of the tampon housing member  12  is about 30 mm. In yet another non-limiting example, the length of the tampon housing member  12  is about 65 mm.  
         [0041]     As shown in  FIG. 2 , in another non-limiting example, the tampon housing member  12  can comprise the accordion collapse zone  39 . This accordion collapse zone  39 , during insertion, can collapse with the force of insertion by the user further exposing the tampon  11  to vaginal tissues. The accordion collapse zone  39  can be made from any suitable type of material known in the art which will bend or fold when the insertion force is applied. For example, the accordion collapse zone  39  can be made from a polymer film or paper.  
         [0042]     ii Cover Member  
         [0043]     Referring to  FIG. 1   b , the cover member  18  is external to the tampon housing member  12 . The cover member  18  has the hollow interior  19 , the top end  20 , and the bottom end  21  opposed to the top end  20 . The top end  20  is the most proximal end of the cover member  18  along the longitudinal axis  60 .  
         [0044]     At least a portion of the hollow interior  19  of the cover member  18  can engage with at least a portion of the exterior of the tampon housing member  12 . In one embodiment, the cover member  18  can be slideable with at least a portion of the tampon housing member  12 .  
         [0045]     Alternatively, the cover member  18  can be fixedly joined to the tampon positioning member  14  in any way known in the art. Also, alternatively, the cover member  18  can be monolithic with the tampon positioning member  14 , for example, by molding the cover member  18  and the tampon positioning member  14  as one piece.  
         [0046]     The manufacturer of tampon applicator  10  can vary the configuration of the cover member  18  and the length of the cover member  18 .  
         [0047]     It is further noted herein that the shape or configuration of the cover member  18  can vary as long as a portion of the tampon housing member  12  can be slideable within the cover member  18 . One skilled in the art can imagine that the cover member  18  might be cylindrical or curved like a banana or any other suitable shape can be possible as long as any such shape would work effectively in expelling the tampon  11  from the tampon applicator  10 . The cover member  18  can be of any suitable cross-sectional shape. Suitable cross-sectional shapes can include, but are not limited to, circular, oval, flattened circular, elliptical, and any combination thereof.  
         [0048]     Also, the cover member  18  can have many designs. As shown in  FIG. 1   b , in one embodiment, the cover member  18  can be scalloped at the top end  20 . The top end  20  is preferably designed to minimize the risk of pinching the vaginal tissue of the wearer. In an alternative embodiment, the top end  20  of the cover member  18  can have a feathered thickness edge.  
         [0049]     The cover member  18  can be of any length. In one non-limiting example, the length of the cover member  18  is about 30 mm. In yet another non-limiting example, the length of the cover member  18  is about 65 mm.  
         [0050]     Referring again to  FIG. 1   b , the cover member  18  can comprise the grip region  41  having a perimeter  42 . The perimeter  42  of the grip region  41  can take essentially any desired shape, including oval, circular, and various other suitable geometric patterns. The gripping region  41  can be created, for example, by outward projections, raised surfaces, or by impressing or compressing the surfaces. The grip region  41  can be substantially circularly shaped, but can also take on more angular formations such as squared. The surface of the grip region  41  can be any kind of surface known in the art. This surface area can provide a desired frictional resistance during insertion of the tampon applicator  10  into the vaginal cavity. Moreover, this surface area can have, for example, a dove pattern created via surface texturing, impressions, and/or indentations.  
         [0051]     Furthermore, it is preferable that the grip region  41  be of sufficient dimension to substantially accept a user&#39;s grip. As used in the specification and claims, the term “user&#39;s grip” means any way of holding the tampon applicator  10  in a hand, e.g., between a thumb and a finger. The grip region  41  need not necessarily extend completely around the perimeter of the outer member  23 . For example, a space can be provided for a decorative marking or a Trademark character. As shown in  FIG. 1   b , the grip region  41  provides for secure handling of the cover member  18 .  
         [0052]     The cover member  18  can be included in the embodiment of the tampon applicator for several reasons. First, the cover member  18  can be used to handle or grip the tampon applicator during insertion into the vaginal cavity. Second, the cover member  18  can provide the gripping area  41  to the tampon applicator which allows a larger portion of the tampon applicator to be inserted into the vaginal cavity because the cover member  18  allows the tampon  11  to travel a greater distance. The gripping area  41 , generally, is not inserted into the vaginal cavity and creates additional length to the tampon applicator. Thus, the cover member  18  can provide additional travel distance by the tampon applicator. Third, the cover member  18  provides more stability during the insertion of the tampon applicator. Finally, referring to  FIG. 1   b , the guard  43  located at the top end  20  of the cover member  18  minimizes the risk of pinching the tissue of the wearer. As discussed above, the guard  43  pushes or plows” tissue away from the lapping position  40  (seen in  FIG. 2 ). The lapping position  40  (seen in  FIG. 2 ) is located between the tampon housing member  12  and the top end  20  of the cover member  18 . Thus, if the cover member  18  is not included, the tampon applicator  10  could inadvertently draw body tissue into the lapping position  40  (seen in  FIG. 2 ) and/or pinch the tissue of the wearer during insertion of the tampon applicator  10  into the vaginal cavity.  
         [0053]     iii Tampon Positioning Member  
         [0054]     Referring to  FIG. 1   b , the tampon positioning member  14  positions the tampon  11  along the length of the tampon housing member  12  so that during expulsion the tampon  11  will travel a pre-determined distance. This predetermined distance ultimately results in the tampon  11  being properly positioned in the vagina. Moreover, this position allows sufficient expulsion such that when the tampon  11  is expelled at least a portion of the tampon  11  is retained within the vagina by body forces.  
         [0055]     The tampon positioning member  14  has a first end  22  and a second end  23  opposed to the first end  22 . The first end  22  is the most proximal end of the tampon positioning member  14  along the longitudinal axis  60 . In addition, the first end  22  of the tampon positioning member  14  can contact the tampon  11  during expulsion of the tampon  11  from the tampon housing member  12 . The second end  23  of the tampon positioning member  14  is the most distal end along the longitudinal axis  60 .  
         [0056]     Referring to  FIG. 1   c , during expulsion, the tampon  11  is in contact with the tampon positioning member  14 . In one non-limiting example, at least a portion of the tampon  11  can rest against the first end  22  of the tampon positioning member  14  during expulsion of the tampon  11  from the tampon applicator  10 . However, the tampon  11  may or may not be in contact with the tampon positioning member  14  before expulsion of the tampon  11  from the tampon applicator  10 . Referring to  FIG. 1   b , for example, in one non-limiting example, before expulsion of the tampon  11  from the tampon applicator  10 , the tampon positioning member  14  can be located in the hollow interior  15  of the cover member  18  without any contact with the tampon  11 .  
         [0057]     The tampon positioning member  14  can be fixedly joined to the tampon housing member  12  and/or the cover member  18  in any way known in the art. The tampon positioning member  14  can also be monolithic with the tampon housing member  12 , for example, by molding the tampon positioning member  14  and the tampon housing member  12  as one piece. Alternatively, the tampon positioning member  14  can be monolithic with the cover member  18 , for example, by molding the tampon positioning member  14  and the cover member  18  as one piece. In one non-limiting example, the tampon positioning member  14  can be fixedly joined to the cover member  18  and/or tampon housing member  12  by friction fitting that snaps parts together, gluing, and/or melting. In another non-limiting example, the tampon positioning member  14  can also be a continuation of the cover member  18  by folding or compressing a portion of the cover member  18  and turning the cover member  18  inwards upon itself to create a tube inside a tube. Likewise, the tampon positioning member  14  can also be a continuation of the tampon housing member  12  by folding or compressing a portion of the tampon housing member  12  and turning the tampon housing member  12  inwards upon itself to create a tube inside a tube.  
         [0058]     It is further noted herein that the shape or configuration of the tampon positioning member  14  can vary as long as the tampon positioning member  14  aids in positioning the tampon  11  along the length of the tampon housing member  12  to provide proper placement of the tampon  11  within a vaginal cavity. As shown in  FIG. 1   b , one embodiment of the tampon positioning member  14  includes an elongated tampon positioning member  14  of a generally tubular shape. Also, as shown in  FIG. 3 , the tampon positioning member can be a rod  27 . The base  13  of the tampon  11  can rest on top of the rod  27 . The base  13  of the tampon  11  is located adjacent the string  28 . The string  28  is attached to the tampon  11 . The string  28  can extend back through the tampon housing member  12 . In another embodiment, the tampon positioning member  14  can be slideable within the tampon housing member  12 .  
         [0059]     As shown in  FIG. 4 , in another alternative embodiment, the tampon positioning member can also comprise projections  24  extending inward from the hollow interior  15  of the cover member  18 . The projections  24  can be of any shape or size as long as the projections  24  allow the tampon  11  to rest on the projections  24 . Specifically, the tampon  11  can rest on a first end  25  of the projections  24 . The projections  24  can be fixedly joined to the cover member  18  and/or tampon housing member  12  in any way known in the art.  
         [0060]     It is further noted herein that the length of the tampon positioning member  14  can vary as long as the tampon positioning member  14  aids the tampon  11  in being located in the pre-determined position within the tampon housing member  12  so that proper placement within the vaginal cavity is achieved. In one non-limiting example, the tampon positioning member  14  can be from about 36 millimeters to about 63 millimeters.  
         [0000]     C. Tampon Applicator Materials  
         [0061]     Different tampon applicator parts can be constructed from different materials and processes. The tampon applicator or any part of the tampon applicator can be formed of a spirally wound, convolutedly wound, or longitudinally seamed hollow tube that is formed from paper, paperboard, cardboard, or any combination thereof. The tampon applicator or any part of the tampon applicator can also be injection molded, extruded, or formed from flexible plastic, such as thermoformed from plastic sheet or folded or wound from plastic film.  
         [0062]     The tampon applicator or any part of the tampon applicator can be constructed from a single ply of material or can be formed from two or more plies that are bonded together to form a laminate. The use of two or more plies or layers is preferred for it enables the manufacturer to use certain materials in the various layers that can enhance the performance of the tampon applicator or any part of the tampon applicator. When two or more plies are utilized, all the plies can be spirally wound, convolutedly wound, or longitudinally seamed to form an elongated cylinder. The tampon applicator or any part of the tampon applicator can be constructed using a smooth thin ply of material on the outside or exterior surface that surrounds a coarser and possibly thicker ply. When the tampon applicator or any part of the tampon applicator contains at least three plies, the middle ply can be the thicker ply, and the interior and exterior plies can be smooth and/or slippery to facilitate expulsion of the tampon and to facilitate insertion of the tampon applicator or any part of the tampon applicator into a woman&#39;s vagina. The tampon applicator or any part of the tampon applicator should contain one to four plies, although more plies can be utilized if desired.  
         [0063]     The plies forming the tampon applicator or any part of the tampon applicator can be held together by an adhesive, such as glue, heat, pressure, ultrasonic, etc. The adhesive can be either water-soluble or water-insoluble. A water-soluble adhesive is preferred for environmental reasons in that the tampon applicator or any part of the tampon applicator will quickly break apart when it is immersed in water. Such immersion will occur should the tampon applicator or any part of the tampon applicator be disposed of by flushing it down a toilet. Exposure of the tampon applicator or any part of the tampon applicator to a municipal waste treatment plant wherein soaking in water, interaction with chemicals, and agitation all occur, will cause the tampon applicator or any part of the tampon applicator to break apart and evenly disperse in a relatively short period of time.
