Description

The present invention relates to an application device for applying a skin adhesive tape, such as a slack prevention tape or a facelift tape, to the skin of the face, etc., and a beauty tool including the application device.

Because facial skin tends to loosen with age, cosmetic surgery has been performed to lift the loose skin and give the face a slimmer and younger appearance, however, such cosmetic surgery is risky, frightening to patients, and expensive.
On the other hand, although fine lines can be reduced by cosmetics or fillers, cosmetics are not sufficient to reduce deep lines and loose skin. Therefore, cosmetic surgery is actually required for facelift, which is effective for loose skin, laugh lines, forehead wrinkles, frown lines, etc. caused by aging on the facial skin above the eyes by lifting the forehead skin after incision. Furthermore, plastic surgery provides a youthful appearance by removing excess fat, muscle stiffness, and reshaping the skin.

Adhesive tapes have been provided to lift the face line and remove loose skin. For example, U.S. Patent No. 5,339,933 describes the use of polyurethane/acrylic tape to reduce wrinkles. Such a tape is applied onto the skin area adjacent to the wrinkle while the tape is stretched.

Patent Document 2 describes an adhesive tape that can be stretched using fingers, which provides a lifting effect by applying opposite ends of the adhesive tape to the front and back of a user's ears, respectively.
Additionally, US Pat. No. 5,399,633 describes a stretch tape for application overnight over the targeted wrinkle.

US Patent No. 5,399,633 describes a telescopic facelift device for the face and neck, which is worn by a user by sticking both adhesive ends of the device onto the user's skin to lift loose skin or reduce wrinkles.
Patent Document 5 describes a face lift device. The device includes two pads to be attached to the skin of a user and a strap attached to the two pads, and the device lifts loose skin by adjusting the length of the strap after the two pads are attached to the skin.

JP 2004-313277 A JP 2016-055140 A U.S. Pat. No. 7,608,090 US Patent Application Publication No. 2014/0243886 U.S. Pat. No. 8,257,385

However, because the user applies the tape while looking in a mirror and stretches the tape with both hands, it is difficult to properly apply the tape to the skin.
Furthermore, the facelift devices are not aesthetically pleasing to the user as the padding and other components of the device are visible from the outside when the device is worn.
SUMMARY OF THE PRESENT EMBODIMENT It is therefore an object of the present invention to provide a skin adhesive tape application device and a beauty tool including the application device.

The present invention employs the following means for solving the above-mentioned problems. The skin adhesive tape application device according to the present invention is an application device for skin adhesive tape for applying a skin adhesive tape including a tape body and a liner detachably applied to the tape body, and includes a housing, a payout gear arranged in the housing to rotate about a first rotation axis and holding a payout reel that holds a roll of the skin adhesive tape, a winding gear arranged in the housing to rotate about a second rotation axis different from the first rotation axis and holding a winding reel that winds up the skin adhesive tape paid out from the payout reel by rotating the payout gear, and an application head arranged between the payout gear and the winding gear in the payout direction of the skin adhesive tape and applies the tape body of the skin adhesive tape to the skin, and is characterized in that the payout gear and the winding gear rotate in conjunction with each other.

According to the present invention, after pressing the application head against the skin to apply one end of the adhesive tape, the application head is moved along the skin to which the skin adhesive tape is to be applied, whereby the payout gear rotates about the first rotation axis to pay out the tape. In this case, since one end of the tape is applied to the skin, the paid out tape is applied with an appropriate tension. Furthermore, the winding gear rotates about the second rotation axis in conjunction with the rotation of the payout gear, and as the tape is paid out from the payout gear, it winds up the liner separated from the tape body.
In this way, after the tape is applied to the skin, the tape is unwound from the payout gear with the proper tension and the liner is wound up by simply moving the application head along the skin, so that the user can easily and properly apply the tape to their skin by themselves.

Furthermore, in the application device according to the present invention, the application head may include a plurality of application rollers arranged in the payout direction of the skin adhesive tape.
According to the present invention, the application head can ensure a sufficient contact area between the skin and the tape when the application head is pressed against the skin, so that the tape can be applied more easily and more properly.

Furthermore, the application device according to the present invention may further include a cutting unit that cuts the tape body of the skin adhesive tape.
According to the present invention, the tape body can be cut at the same time when the appropriate length of the tape is applied onto the skin without using a separate cutting unit. Therefore, the operability of the application device can be improved. Since the cutting unit does not cut the liner, the cutting effect by the cutting unit does not affect the unwinding and winding of the tape.

Furthermore, in the application device according to the present invention, the cutting unit may be arranged upstream of the application head in the payout direction of the skin adhesive tape.
According to the present invention, the tape body can be cut at the same time that the other end of the tape is applied onto the skin using the application head.

Furthermore, in the application device according to the present invention, a passage may be formed between the application head and the cutting unit.
According to the invention, the tape is guided between the application head and the cutting unit, so that the tape can be unwound more properly.

Furthermore, in the application device according to the present invention, the application device may further include an interlocking gear that interlocks rotation of the pay-out gear with rotation of the wind-up gear.
According to the present invention, the pay-out gear and the winding gear can be arranged in various layouts by interlocking the rotation of the pay-out gear with the rotation of the winding gear by the interlocking gear.

Furthermore, in the application device according to the present invention, the payout gear may removably hold the payout reel which holds the roll of the skin adhesive tape, and the winding gear may removably hold the winding reel which holds the wound up skin adhesive tape.
According to the invention, the supply and take-up reels can be replaced together with the tape and the application device is reusable.

Furthermore, in the application device according to the present invention, the application head can be disposed closer to the payout gear than to the winding gear in the payout direction of the skin adhesive tape.
According to the invention, the length of the path of the tape from the payout gear to the application head is reduced so that the risk of applying an object onto the adhesive surface of the tape being paid out from the payout gear to the application head may be reduced.

A beauty tool according to the present invention is characterized by comprising a skin adhesive tape including a tape body and a liner detachably attached to the tape body, and the application device described above.
According to the present invention, after the tape is applied to the skin, the tape can be unwound from the unwinding gear with the appropriate tension, the liner can be wound, and the tape body can be cut to the required length by the cutting mechanism by simply moving the application head along the skin in the same manner as described above. Thus, the user can easily and properly apply the tape to the skin by himself or herself.

FIG. 2 is a schematic diagram of a skin adhesive tape application device according to one embodiment of the present invention (with the second half removed for clarity). 1 is a schematic diagram of a skin adhesive tape application device with the supply reel, take-up reel and tape removed. FIG. FIG. 1 is a perspective view of a skin adhesive tape. FIG. 4 is a cross-sectional view of the skin adhesive tape shown in FIG. 3. FIG. 2 is an enlarged view of the application head shown in FIG. 1 . 1 shows the skin before tape is applied (a) and after tape is applied (b).

Hereinafter, an embodiment of a skin adhesive tape application device (hereinafter referred to as an application device) and a beauty tool including the application device according to the present invention will be described with reference to the drawings. Note that the scale of each of the drawings used in the following description has been appropriately changed so that each component can be recognized.

A cosmetic tool 1 according to an embodiment of the present application shown in Figs. 1 and 2 includes a skin adhesive tape T (hereinafter referred to as a tape) and a skin adhesive tape application device 10 (hereinafter referred to as an application device).
As shown in Figures 3 and 4(a), the tape T includes a tape body 14 including a film layer 11, a first adhesive layer 12 provided on one side of the film layer 11, and a second adhesive layer 13 provided on the opposite side of the film layer 11, and a liner 15 attached on the first adhesive layer 12.
The film layer 11 is made of, for example, polyurethane and is transparent. Furthermore, the thickness of the film layer 11 is, for example, 100 micrometers or less, preferably between 20 micrometers and 80 micrometers, and more preferably 50 micrometers. The material of the film layer 11 is not limited to polyurethane, and may be another suitable polymer material, or another suitable material other than a polymer material.

The first adhesive layer 12 is, for example, an acrylic adhesive, and the mass of the first adhesive layer 12 per unit area is, for example, less than 10 g/m ² (ie 10 gsm), preferably between 0 gsm and 8 gsm, more preferably 2 gsm.
The second adhesive layer 13 is an acrylic adhesive like the first adhesive layer 12, and the mass of the second adhesive layer 13 per unit area is 50 gsm or less, preferably less than 30 gsm. Therefore, the adhesive strength of the second adhesive layer 13 is higher than that of the first adhesive layer 12. Furthermore, the adhesive strength of the first adhesive layer 12 and the second adhesive layer 13 can be changed as long as the liner 15 can be separated from the tape body 14 without separating the tape body 14 from the skin when the tape body 14 is applied onto the skin.

The liner 15 is formed, for example, from paper, although the material of the liner 15 may be another suitable material other than paper.
1, a tape T having the configuration described above is wound around a supply reel 16 and a distal end of the tape T is attached to a take-up reel 17. The tape T has a length of at least one meter. The length of the tape T may be varied.

As shown in Figures 1 and 2, the application device 10 includes a housing 21, a payout gear 22 arranged in the housing 21 to rotate around a first rotation axis A, a winding gear 23 arranged in the housing 21 to rotate around a second rotation axis B different from the first rotation axis A, an application head 24 that applies tape T to the skin, a cutting unit 25 that cuts the tape body 14 of the tape T, and an interlocking gear 26 arranged in the housing 21 to rotate around a third rotation axis C different from the first rotation axis A and the second rotation axis B.

The housing 21 is made of a transparent material, for example a plastic material, so that the inside of the housing 21 can be seen from the outside. Furthermore, the housing 21 includes a first half 21 and a second half (not shown) that are removably assembled to each other. The first half 21 is provided with a first shaft 31 to a third shaft 33 to which a payout gear 22, a winding gear 23, and an interlocking gear 26 are respectively rotatably attached. The housing 21 may be made of a suitable opaque material.

The payout gear 22 is rotatably supported by the first half 21 having the first shaft 31. The payout gear 22 holds the payout reel 16 so that the payout reel 16 can rotate together with the payout gear 22 about the first rotation axis A. The payout gear 22 rotates about the first rotation axis A to pay out the tape T wound around the payout reel 16.
The winding gear 23 is rotatably supported by the first half 21 having the second shaft 32. The winding gear 23 holds the winding reel 17 so that the winding reel 17 can rotate together with the winding gear 23 about the second rotation axis B. The winding gear 23 rotates about the second rotation axis B to wind up the tape T that is unwound from the supply reel 16 and passes through the application head 24.

The application head 24 is supported by the housing and protrudes from an opening 21A formed in the housing 21. As shown in Figures 1, 2 and 5, the application head 24 includes an application head body 41 supported by the housing 21, and three application rollers 42 to 44 rotatably supported by the application head body 41.
The joining rollers 42 to 44 are rotatable about their respective rotation axes and are disposed along the payout direction of the tape T.

1 and 2, the cutting unit 25 is supported by the housing 21 and protrudes from an opening 21A formed in the housing 21 so that the cutting unit 25 moves toward and away from the application head 24. The cutting unit 25 is formed from a plastic material, similar to the housing 21, and includes a cutting edge 51 that cuts the tape body 14 of the tape T. The cutting unit 25 is disposed between the payout gear 22 and the application head 24 in the payout direction of the tape T, and is disposed closer to the application head 24 than the payout gear 22 in the payout direction of the tape T.

The interlocking gear 26 is rotatably supported by the first half 21 including the third shaft 33. The interlocking gear 26 meshes with the pay-out gear 22 and the take-up gear 23. Therefore, the interlocking gear 26 transmits the rotational motion of the pay-out gear 22 to the take-up gear 23, interlocking the rotation of the pay-out gear 22 with the rotation of the take-up gear 23.
The application device 10 includes a guide member such as a guide roller 61 for guiding the tape T from the pay-out reel 16 to the take-up reel 17 in the pay-out direction of the tape T. The guide roller 61 is disposed between the pay-out gear 22 and the application head 24 in the pay-out direction of the tape T, and is rotatably supported by the first half 21 so as to rotate about its axis of rotation. The guide roller 61 ensures that the pay-out path of the tape T from the guide roller 61 to the application roller 42 of the application head 24 is not altered even when the outer diameter of the roll of tape T wound around the pay-out reel 16 becomes smaller as the tape T is paid out from the pay-out reel 16.

Next, a method of using the application device 10 and the beauty tool 1 including the application device 10 having the above-described structure will be described.
First, the supply reel 16 and the take-up reel 17 are attached to the supply gear 22 and the take-up gear 23, respectively. In this case, an appropriate length of tape T is paid out from the supply reel 16 and passes through application rollers 42 to 44 of the application head 24. After the supply reel 16 and the take-up reel 17 are attached, the tape body 14 of the tape T is pre-cut at a position downstream of the application head 24 in the payout direction of the tape T.

When tape T is applied to the skin, the application head 24 is pressed against the skin. Thus, one end of the tape body 14 is applied to the skin S. After one end of the tape body 14 is applied to the skin in the direction of arrow M, the application head 24 and the application device 10 are moved along the skin. In this case, since one end of the tape body 14 is applied to the skin, the tape T is pulled as the application device 10 moves, and the payout gear 22 rotates around the first rotation axis A in the direction of arrow R1, and therefore the tape T is unwound from the payout reel 16.

The rotation of the payout gear 22 is transmitted to the winding gear 23 via the interlocking gear 26. Therefore, when the application head 24, and therefore the application device 10, is moved along the skin S, the winding gear 23 rotates around the second rotation axis B in the direction of the arrow R2. The tape T paid out from the payout reel 16 adheres to the skin, and since the adhesive force between the film layer 11 and the first adhesive layer 12 is smaller than that between the film layer 11 and the second adhesive layer 13, the liner 15 is separated from the tape body 14 and taken up by the winding reel 17, as shown in FIG. 4(b). Furthermore, the skin is pulled while the tape T is being unwound. Therefore, the tape T applied to the skin S is applied with an appropriate tension. When the tape T passes through the application rollers 42 to 44, the tape T paid out from the payout reel 16 is smoothly paid out without damage to the tape T or with reduced damage to the tape T by rotating the application rollers 42 to 44.
After an appropriate length of tape T has been unwound, the other end of tape body 14 is applied onto the skin, and tape body 14 of tape T is cut by cutting unit 25 .

When the liner 15 is separated from the tape body 14, the first adhesive layer 12 remains on the film layer 11, but the first adhesive layer 12 may be separated from the tape body 14 together with the liner 15. When the first adhesive layer 12 remains on the film layer 11, cosmetics such as foundation are often applied onto the skin when applying makeup after applying the tape body 14 to the skin.
In this manner, the application device 10 is used.
Here, Figures 6(a) and 6(b) show the skin before and after application of tape T. As shown in Figures 6(a) and 6(b), the portion of the skin having a length of 5 cm before application of tape T has a length of 4 cm, indicating that application of tape T has a pulling effect on the skin. In Figure 6(b), tape T is applied to the skin by sticking one end of tape T onto the skin and then pulling tape T downward.

As described above, with the application device 10 and the beauty tool 1, after one end of the tape T is applied to the skin, the tape T can be unwound from the payout reel 16 while applying an appropriate tension to the tape T by simply moving the application head 24 along the skin. This allows the user to more easily and properly apply the tape T to the user's skin.

Furthermore, since the three application rollers 42 to 44 are provided on the application head 24, pressing the application head 24 against the skin ensures a sufficient contact area between the application head 24 and the skin via the tape T, making it possible to apply the tape T more easily and properly.
Furthermore, it is possible to cut the tape body 14 by the cutting unit 25 after an appropriate length of the tape T has been applied onto the skin, without using a separate cutting unit. In this case, the cutting unit 25 does not cut the liner 15, so the cutting effect of the cutting unit 25 does not affect the payout and take-up of the tape T. Furthermore, by guiding the tape T between the application head 24 and the cutting unit 25, the tape T can be fed more properly.

Furthermore, by indirectly interlocking the rotation of the pay-out gear 22 and the rotation of the winding gear 23 using the interlocking gear 26, the pay-out gear 22 and the winding gear 23 can be arranged in various layouts.
Furthermore, since the payout gear 22 and the winding gear 23 are removably attached to the payout reel 16 and the winding reel 17, respectively, the application device 10 can be reused by replacing the payout reel 16 and the winding reel 17 together with the tape T even after the tape T has been used up.
Furthermore, by positioning the application head 24 closer to the payout gear 22 than to the take-up gear 23 in the payout direction of the tape T, and by shortening the length of the path of the tape T from the payout gear 22 to the application head 24, the risk of an object being attached onto the second adhesive layer 13 of the tape T being paid out from the payout gear 22 can be reduced.

The present invention is not limited to the above-described embodiments, and various modifications to the above embodiments may be made without departing from the inventive concept of the present invention.
Although the application head includes three application rollers, the application head may include only one application roller or a different number of application rollers. Further, the application head may include any suitable members other than application rollers, such as pads formed from sponge.
The cutting unit may be provided downstream of the application head and may consist of any suitable cutting edge, such as a cutting edge made of any suitable material other than plastic, or may consist of a scissors-like cutting unit or any other unit, such as a cutting unit that cuts the tape body with a laser or heat.
The tape passes between the application head and the cutting unit, the location of which may vary.
The supply reel and the take-up reel may be non-removably attached to the supply gear and the take-up gear, respectively, i.e., the supply reel may be formed integrally with the supply gear and the take-up reel may be formed integrally with the take-up gear.
The arrangement of the payout gear and the take-up gear may be different, i.e. the application head may be located closer to the take-up gear than the payout gear in the tape payout direction. Furthermore, two or more interlocking gears may be used to interlock the rotation of the payout gear with the rotation of the take-up gear, or different transmission units such as belts may be used to interlock the rotation of the payout gear with the rotation of the take-up gear. Moreover, the payout gear and the take-up gear may directly mesh with each other without using an interlocking gear.
The application device may include a mechanism for adjusting the tension applied to the tape by the payout gear and the take-up gear. Providing such a mechanism for adjusting the tension applied to the tape is advantageous because the outer diameter of the roll of tape decreases as the tape is paid off the payout reel and the tension applied to the tape may change.
The tape may be wound into a roll with the tape body pre-cut to each predetermined length, in which case the cutting unit may be omitted.
