SUMMARY OF THE INVENTION
The present invention contemplates an applicator for a member comprising the member having a surface, with a flexible applicator along the surface and having a convolution so as to double the applicator upon itself to form parallel walls with the convolution there-between. The surface of the member may be exposed by relative movement of one of the wall0 of the appltcator with respect to t,le member. In a speciEic arranyement, the member is enclosed in~ide a flexible applicator sleeve with the convolution along the sleeve, permitting the sleeve to be rolled along a direction substantially parallel with a central axis of the member.
A preferred embodiment of the present invention contemplates an applicator and tampon, in which the tampon is formed of an oblong absorbent member having a central axis and a forward end adapted to be extended first into the vagina. A flexible applicator sleeve is fitted about the tampon and overlapping a portion of the forward end of the tampon, with a convolution along the sleeve permitting the sleeve to be rolled along a ~1~72805 direction substantially parallel with the central axis during or after movement of the tampon into the vagina.
Fcr these purposes, the term "convolution" means a single roll, with a portion of the sleeve about another portion of the sleeve.
In one embodiment of the present invention, the flexible applicator sleeve surrounds the tampon and has a longitudinal slit. The slit extends from one end of the tampon to one extremity of the sleeve, and may pref-erably have perforations along the line which is alignedwith the slit, but adjacent the tampon. The sleeve may be fitted with a second slit extending from the other extremity of the sleeve, the second slit being out of alignment with the fir~t slit. In use, the first slit permits the sleeve to be rolled backward substantially parallel with the central axis of the tampon to form the convolution, and thereafter facilitate relative move-ment of the tampon with respect to the sleeve~ In this regard, the conventional stick or similar means may be used to push the tampon upward, open~ the distal end oE
the sleeve to permit access to the tampon.

3(1 5 D AILED DESCRIPTION OF THE PREFERRED EMBODIMENT
An applicator and tampon in accordance with the present invention and its manner of intended use will now be described in reference to Figures 1, 2 and 3.
The applicator and tampon, referred to ~enerally by the reference numeral (10), includes a tampon (12) com-prising an absorbent fiber body, which is compressed to such an extent that it is substantially stable under nor~al atmospheric conditions but expands when wetted as during its intended use. The tampon (12) is provided with a conventional insertion rod (14) which may com-prise wood, paper or any other material of a suitable naturel and which is appropriately joined at the distal end (16) of the tampon (12). The applicator and tampon is further provided with a conventional withdrawal string (18) suitably anchored to the tampon (12) and exists adjacent to the distal end (16).
The applicator, referred to generally by the refer-ence numeral (20), comprises a flexible sleeve about thetampon and overlapping a portion of the forwa:rc3 end (22) of the tampon (12). A suitable mater.ial for use as the sleeve (20) may be, Eor example, polyethylene or poly-propylene or other material having sufficient flex-ibility to form the desired convolution.
The sleeve (20) is wrapped about the tampon (12) insuch a manner as to form a convolution (24) toward the forward end (22) of the tampon (12), the convolution forming an opening (26) axial with the central axis of the tampon (12) and overlapping the forward end (22).
The convolution (24) thus separates the sleeve (20) into two sidewalls (28) and (30), the first sidewall (28) being next adjacent to the tampon (12), and the outer ~t7z~0s sidewall (30) being next adjacent to the firs-t wall (28).
The manner in which the applicator and tampon (10) is employed will now be described with re~erence to Figures 2 and 3.
Noting Figure 2, the applicator and tampon (10) are inserted into the vagina, with the muscle tissue coming in contact with the outer wall (30) of the sleeve (20).
As the tampon (12) is forced into the vagina by applica-tion of pressure on the insertion rod (14), the sleeve(20) rolls at the convolution (24), with the outer wall (30) remaining substantially stationary. After the tam-pon is inserted in the desired manner, the insertion rod (14) may be removed in a conventional fashion by rota-tion thereo~, and the sleeve (20) may be removed bysimply pulling the outer extremity of the outside wall (30) away from the vagina. Alternatively, the tampon (12) is placed into position and the sleeve (20) is re-moved while the tampon remains relatively stationary.
It will thus be seen that a tampon and applicator con-structed in accordance wikh the present invention reduces signiEicantly the amount of tampon insertion discomEort. Further, the use of the thin poly-resin sleeve (20) provldes relatively e~sy entry during the insertion process.
It will be understood that the sleeve (20) may be coated with an appropriate lubricant. It will be further understood that the sleeve (20) may be adapted for use with tampons of different sizes and configura-tions, i.e., rectangular or other shapes.
While the applicator has been described above ~oruse with tampons, it will be understood that the appli-cator may be employed with other products as well.
s ~ 6 --A second embodiment of the applicator and tampon in accordance with the present invention will now be described with reEerence to Figures 4, 5, and 6. The combination applicator and tampon, referred to gener-ally by the reference numeral (50), includes a tampon(52) having a longitudinal central axis. The tampon (52) includes a conventional insertion rod (54) and a withdrawal string (58) suitably anchored to the tampon (52) adjacent the distal end thereof. The applicator, referred to generally by the reference numeral (60), comprises a flexible sleeve about the tampon (52) and overlapping the forward and rearward ends of the tampon.
As is clearly shown in Figure 4, the applicator sleeve (60) surrounds the tampon (52) and has a longi-tudinal slit (62) along a portion thereof substantiallyparallel with the central axis of the tampon. This slit (62) extends from one end of the tampon (52) through the forward extremity (64) of the sleeve (60). With contin-uous reference to Figure 4, the sleeve (60) furkher includes a perforated line (66) which is aligned with the slit (62) adjacent the t~mpon (52). The applicator sleeve (60) of Figures 4, 5, and 6 further preEerably include a ~econd slit (68) in the sleeve extending from the other extremity (70), the slit being out of align-ment with the first slit (62). In the embodiment shownin Figure 4, second slit (68) is out of alignment with slit (62) by 180. However, it will be understood that the second slit (68) need not necessarily be parallel with the central axis of the tampon (52), but preferably is so parallel with that axis.
The mode of operation of the applicator and tampon (50) of ~igures 4, 5, and 6 will now be described with reference to Figures 5 and 6.
.
~7z13()S
Firs~, note in Figure 5, the applicator slee~e (60) is initially folded back along the convolution (72) adjacent the forward extremity of the tampon (52), and the tampon and applicator combination (50) has been inserted. As is shown in Figure 6, the insertion rod (54) is then pushed forward, causing the tampon (52) to move forward into the appropriate position in the vagina. The use of the insertion rod (54) (or other means, such as the user's finger) is facilitated by the wider opening at the distal extremity (73) of the sleeve (60), effectuated by the second slit (68). The sleeve (60) may then be removed along with the insertion rod (54)-While the second embodiment of Figures 4, 5, and 615 has been disclosed as including both first and second slits (62) and (68), as well as a perforated line (66), it will be appreciated by those skilled in the art that the arrangement here disclosed may include only the first or second slit alone or in combination with the perforated line (66)o
An applicator and tampon in accordance with the present invention and its manner of intended use will now be described in reference to Figures 1, 2 and 3.
The applicator and tampon, referred to ~enerally by the reference numeral (10), includes a tampon (12) com-prising an absorbent fiber body, which is compressed to such an extent that it is substantially stable under nor~al atmospheric conditions but expands when wetted as during its intended use. The tampon (12) is provided with a conventional insertion rod (14) which may com-prise wood, paper or any other material of a suitable naturel and which is appropriately joined at the distal end (16) of the tampon (12). The applicator and tampon is further provided with a conventional withdrawal string (18) suitably anchored to the tampon (12) and exists adjacent to the distal end (16).
The applicator, referred to generally by the refer-ence numeral (20), comprises a flexible sleeve about thetampon and overlapping a portion of the forwa:rc3 end (22) of the tampon (12). A suitable mater.ial for use as the sleeve (20) may be, Eor example, polyethylene or poly-propylene or other material having sufficient flex-ibility to form the desired convolution.
The sleeve (20) is wrapped about the tampon (12) insuch a manner as to form a convolution (24) toward the forward end (22) of the tampon (12), the convolution forming an opening (26) axial with the central axis of the tampon (12) and overlapping the forward end (22).
The convolution (24) thus separates the sleeve (20) into two sidewalls (28) and (30), the first sidewall (28) being next adjacent to the tampon (12), and the outer ~t7z~0s sidewall (30) being next adjacent to the firs-t wall (28).
The manner in which the applicator and tampon (10) is employed will now be described with re~erence to Figures 2 and 3.
Noting Figure 2, the applicator and tampon (10) are inserted into the vagina, with the muscle tissue coming in contact with the outer wall (30) of the sleeve (20).
As the tampon (12) is forced into the vagina by applica-tion of pressure on the insertion rod (14), the sleeve(20) rolls at the convolution (24), with the outer wall (30) remaining substantially stationary. After the tam-pon is inserted in the desired manner, the insertion rod (14) may be removed in a conventional fashion by rota-tion thereo~, and the sleeve (20) may be removed bysimply pulling the outer extremity of the outside wall (30) away from the vagina. Alternatively, the tampon (12) is placed into position and the sleeve (20) is re-moved while the tampon remains relatively stationary.
It will thus be seen that a tampon and applicator con-structed in accordance wikh the present invention reduces signiEicantly the amount of tampon insertion discomEort. Further, the use of the thin poly-resin sleeve (20) provldes relatively e~sy entry during the insertion process.
It will be understood that the sleeve (20) may be coated with an appropriate lubricant. It will be further understood that the sleeve (20) may be adapted for use with tampons of different sizes and configura-tions, i.e., rectangular or other shapes.
While the applicator has been described above ~oruse with tampons, it will be understood that the appli-cator may be employed with other products as well.
s ~ 6 --A second embodiment of the applicator and tampon in accordance with the present invention will now be described with reEerence to Figures 4, 5, and 6. The combination applicator and tampon, referred to gener-ally by the reference numeral (50), includes a tampon(52) having a longitudinal central axis. The tampon (52) includes a conventional insertion rod (54) and a withdrawal string (58) suitably anchored to the tampon (52) adjacent the distal end thereof. The applicator, referred to generally by the reference numeral (60), comprises a flexible sleeve about the tampon (52) and overlapping the forward and rearward ends of the tampon.
As is clearly shown in Figure 4, the applicator sleeve (60) surrounds the tampon (52) and has a longi-tudinal slit (62) along a portion thereof substantiallyparallel with the central axis of the tampon. This slit (62) extends from one end of the tampon (52) through the forward extremity (64) of the sleeve (60). With contin-uous reference to Figure 4, the sleeve (60) furkher includes a perforated line (66) which is aligned with the slit (62) adjacent the t~mpon (52). The applicator sleeve (60) of Figures 4, 5, and 6 further preEerably include a ~econd slit (68) in the sleeve extending from the other extremity (70), the slit being out of align-ment with the first slit (62). In the embodiment shownin Figure 4, second slit (68) is out of alignment with slit (62) by 180. However, it will be understood that the second slit (68) need not necessarily be parallel with the central axis of the tampon (52), but preferably is so parallel with that axis.
The mode of operation of the applicator and tampon (50) of ~igures 4, 5, and 6 will now be described with reference to Figures 5 and 6.
.
~7z13()S
Firs~, note in Figure 5, the applicator slee~e (60) is initially folded back along the convolution (72) adjacent the forward extremity of the tampon (52), and the tampon and applicator combination (50) has been inserted. As is shown in Figure 6, the insertion rod (54) is then pushed forward, causing the tampon (52) to move forward into the appropriate position in the vagina. The use of the insertion rod (54) (or other means, such as the user's finger) is facilitated by the wider opening at the distal extremity (73) of the sleeve (60), effectuated by the second slit (68). The sleeve (60) may then be removed along with the insertion rod (54)-While the second embodiment of Figures 4, 5, and 615 has been disclosed as including both first and second slits (62) and (68), as well as a perforated line (66), it will be appreciated by those skilled in the art that the arrangement here disclosed may include only the first or second slit alone or in combination with the perforated line (66)o
