Technical Field

[0001] The present disclosure relates to a sagging corrector.

Background Art

[0002] Since the functions of the facial skin and muscles decline with aging, sagging and wrinkles may appear on the forehead, cheeks, outer corners of the eyes, and mouth corners of the face. The lower part of the face from below the ear to the jaw is also likely to sag under the influence of gravity, and improving or eliminating such sagging is an important issue for women. Therefore, conventionally, in order to improve or eliminate sagging, measures such as applying a nourishing cream and massaging with fingertips or performing facial exercises have been taken.

[0003] On the other hand, in order to fundamentally improve or eliminate sagging, there are also ideas such as receiving treatments called injection of hyaluronic acid or collagen, treatment using light, or feather lift using threads, or undergoing cosmetic plastic surgery to remove sagging skin. However, some women are hesitant to insert instruments or foreign substances such as scalpels into their own skin. In addition to the risks of damaging the skin or causing inflammation, these treatments and cosmetic plastic surgeries also have problems such as high costs, the need to visit a dermatologist or beauty clinic, and being troublesome.

[0004] Patent Document 1 discloses a sagging corrector having a structure that is suitable for long-term wearing without being conspicuous during wearing and without causing discomfort or a sense of strangeness to the wearer, and is easy to increase the pulling-up width, and a sagging correction method using the sagging corrector.

Embodiments for Carrying Out the Invention

[0020] Hereinafter, embodiments of the present invention will be described. The same reference numerals are used for the same elements, and redundant descriptions are omitted. In this example, descriptions of techniques that are already known are omitted. Also, the devices and methods for embodying the technical idea of the invention are exemplified, and the technical idea of the present invention is not limited to the following. The technical idea of the present invention can be variously modified within the scope of the matters described in the claims. In particular, it should be noted that the drawings are schematic and different from the actual ones.

[0021] The sagging corrector 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. Here, FIG. 1 is a diagram showing the configuration of the sagging corrector 1 according to an embodiment of the present invention, (a) is a front view, (b) is a rear view, (c) is a side view in the length direction, (d) is a side view in the width direction, and (e) is a side view in the width direction.

[0022] FIG. 2 is a perspective view of the sagging corrector 1 according to an embodiment of the present invention. FIG. 3 is a perspective view when the sagging corrector 1 according to an embodiment of the present invention is held by hand H. FIG. 4 is a perspective view when the sagging corrector 1 according to an embodiment of the present invention is held by hand H and stretched.

[0023] As shown in Figures 1 to 4, the sagging correction device 1 comprises a thin, elongated base 3 that is expandable and contractible, and adhesive parts 2 formed at both ends of the base 3 that can be attached to the skin. The base 3 and the adhesive parts 2 overlap and are joined together, and the restorative force of the base 3 lifts and fixes the skin. A protective tape separator 4 is attached to the adhesive parts 2. This tape separator 4 is peeled off and the device is attached to the face. Furthermore, a carrier film 5 is attached to the back side of the base 3.

[0024] The thickness of the base 3 is 30-50 μm, and the tensile stress in the longitudinal direction of the base 3 is 45 kgf / cm². 2 This concludes the explanation. This method allows the base 3 to be made thinner, which not only makes it less noticeable during wear but also reduces the likelihood of the wearer experiencing discomfort or unease, making it suitable for prolonged wear. Furthermore, even with its thin profile, the base 3 can withstand a tensile stress of 45 kgf / cm² in the longitudinal direction. 2 Since the above conditions are met, the amount of skin lifting can be increased, resulting in a superior sagging correction effect.

[0025] The adhesive strength of the attachment portion 2 is such that the SP adhesive strength is 4.0 N / 19 mm or more, the BP adhesive strength is 4.0 N / 19 mm or more, the SB adhesive strength is 3.0 N / 19 mm or more, and the release paper release strength is 1.0 N / 50 mm or less. In this way, good adhesive strength that can withstand the restorative force of the base portion 3 is ensured when attached to the skin, enabling the sagging correction device 1 to be worn for extended periods.

[0026] The shape of the area of ​​the adhesive portion 2 that can be attached to the skin is elliptical or semicircular, with dimensions in the width direction perpendicular to the length direction being 10 to 50 mm, more preferably 30 to 40 mm. This ensures that the adhesive area is not only inconspicuous during wear but also durable enough for prolonged wear.

[0027] The area of ​​the adhesive portion 2 that can be attached to the skin has a smaller length dimension than the width dimension perpendicular to the length dimension. This allows for a sufficient adhesive area to withstand prolonged wear while keeping the overall length of the sagging correction device 1 to a minimum.

[0028] The total length of the sagging correction device 1 is 60 to 250 mm, and the length of the base 3, excluding the length overlapping with the adhesive part 2, is 50 to 150 mm. In this way, a sagging correction device 1 suitable for correcting facial sagging is obtained.

[0029] The base portion 3 is made of polyurethane film, and the adhesive portion 2 is made of polyethylene film. In this configuration, the combination of a polyurethane film with excellent elasticity and a polyethylene film suitable for adhesion to the skin provides a skin lifting device 1 that can be worn for extended periods.

[0030] The dimensions of the base portion 3 in the width direction perpendicular to the length direction are larger in the area overlapping with the adhesive portion 2 than in the area not overlapping with the adhesive portion 2. In this way, the bonding area between the base portion 3 and the adhesive portion 2 can be increased without impairing the elasticity of the base portion 3, thereby increasing the bonding strength between the base portion 3 and the adhesive portion 2.

[0031] In the region where the base 3 overlaps with the adhesive portion 2, the dimension in the width direction, which is perpendicular to the length direction, increases as it approaches both ends of the base 3 in the length direction. This allows the ends of the base 3 to be widened without creating a step, which not only increases the bonding area and bonding strength between the base 3 and the adhesive portion 2, but also allows the sagging correction device 1 to have a streamlined, inconspicuous shape without any steps.

[0032] Next, the specific configuration and features of the sagging correction device 1 according to this embodiment will be described.

[0033] The base 3 of this embodiment is made of a stretchable sheet material, specifically a thin film of ether polyurethane with a thickness of 30-50 μm. It is a semi-transparent and inconspicuous material with excellent elasticity and tensile strength. In terms of material properties, it has excellent flexibility, rubber elasticity, and strong friction resistance. It also does not change at low temperatures and is less affected by the environment. It also has excellent water resistance. It is breathable, which reduces stuffiness. It also complies with the Food Sanitation Law. Its main applications include elastic members, vibration dampers, medical materials (such as acne patches), and anti-slip agents.

[0034] The adhesive portion 2 of this embodiment is made of an adhesive sheet material, specifically a thin film adhesive sheet with a thickness of 50 to 200 μm. This material is used for the adhesion of Class 3 pharmaceuticals such as bandages, and it offers excellent adhesion while reducing the burden on the skin.

[0035] Furthermore, the sagging correction device 1 of this embodiment provides a new lift-up method that applies advanced thin-film technology used as a medical material in Japan, and is flexible and easy to apply. There is no risk of tearing when stretched, and it does not shrink excessively, so there is no risk of peeling off, and stress on the skin is reduced.

[0036] The sagging correction device 1 allows you to change the application location and angle depending on your concerns about sagging skin. For example, it is effective for orbital ptosis, lifting sagging eyelids, reducing crow's feet, enhancing eye definition, lifting the face line, and tightening nasolabial folds. It is particularly suitable for people who are concerned about sagging cheeks, jawline, and under the chin, as well as those with orbital ptosis or sagging eyelids that have resulted in single eyelids.

[0037] Next, an example of using the sagging correction device 1 will be explained with reference to Figure 5.

[0038] Figure 5(a) shows the case where the device is wrapped around the head to correct sagging of the forehead, and (b) shows the case where the sagging correction device 1 is concealed with hair.

[0039] When correcting facial sagging using the sagging correction device 1, as shown in Figures 5(a) and (b), the stretched base 3 is wrapped around the back of the head, one adhesive part 2 is attached to one end of the forehead from the rear, and the other adhesive part 2 is attached to the other end of the forehead from the rear. Alternatively, as shown in Figure 5(a), one adhesive part 2 may be attached to one end of the forehead from the rear, then the base 3 is stretched and wrapped around the back of the head, and then the other adhesive part 2 is attached to the other end of the forehead from the rear. With this method of use, facial sagging can be effectively corrected by pulling the forehead to the left and right and backward with the restoring force of the base 3. Also, when concealing the sagging correction device 1 with hair, the hair can be tied up beforehand before attaching the sagging correction device 1, and then the tied hair can be let down after attachment to conceal the sagging correction device 1 with hair.

[0040] Here, Table 1 discloses the data for base 3. [Table 1]

[0041] Table 2 discloses the data for the pasting section 2. [Table 2]

[0042] Although each embodiment has been described in detail above, the invention is not limited to any particular embodiment, and various modifications and changes are possible within the scope described in the claims. Furthermore, it is possible to combine all or more of the components of the embodiments described above. [Industrial applicability]
