Description

  The present invention relates to a nail enamel remover for removing enamel such as manicure to be applied to fingernails of a hand and pedicure to be applied to toenails of a toe.

  An example of a conventional nail enamel remover is disclosed in Japanese Patent No. 5358752 (Patent Document 1).

  The fingertip care device (nail enamel remover) disclosed in Patent Document 1 has a cylindrical sponge body having a gear-like protrusion on the outer peripheral surface, and a container body that accommodates the sponge body. The sponge body is inserted into the container body in a state where a part of the sponge body is folded back into the hollow portion to form a folded portion. The container body has an anti-slip member provided on the inner peripheral surface of the lower region thereof so as to protrude so as to engage with the groove portion of the outer peripheral surface of the sponge body. In a preferred fingertip care device, a finger locking ring is fitted to the upper opening edge of the container body in order to prevent the sponge body from falling off the container body. The finger locking ring comes into contact with the folded portion of the sponge body in a ring shape. The sponge body is impregnated with an enamel removal liquid.

  When removing the nail enamel using the above fingertip care device, the fingernail is inserted into the hollow portion of the sponge body, and the container body is rotated without rotating the finger. Alternatively, the finger is rotated without rotating the container body. Since the groove portion on the outer peripheral surface of the sponge body is engaged with the anti-slip member of the container body, the sponge body rotates together with the container body or stops together with the container body. Therefore, the sponge body that rotates relative to the fingernail rubs the surface of the fingernail to remove enamel.

Japanese Patent No. 5358752

  In order to remove the nail enamel with the above fingertip care device, it is necessary to ensure that the relative rotation between the sponge body and the nail surface is performed. Since the groove on the outer peripheral surface of the sponge body and the inner surface anti-slip member in the lower region of the container body are engaged, the sponge body and the container body are securely engaged in the lower region away from the upper opening of the container body. In either case, both rotate as a unit or stop as a unit. However, an anti-slip member that engages with the outer peripheral surface groove of the sponge body is not provided in the region of the upper opening of the container body into which the finger is inserted.

  When the finger is inserted into the hollow part of the sponge body, the sponge body surrounds the finger and tries to follow the movement of the finger. Therefore, when the container body is rotated relative to the finger, the lower part of the sponge body that is far from the insertion opening reliably rotates relative to the finger. As a result, twisting may occur between the insertion portion and the lower portion of the sponge body. The finger locking ring fitted to the upper opening edge of the container body is in surface contact or line contact with the folded part of the sponge body in a ring shape, but because the engagement force between them is weak, slippage occurs between them. End up.

  An object of the present invention is to provide a nail enamel remover in which a sponge body in an insertion opening portion into which a finger is inserted can reliably rotate relative to a fingernail.

  A nail enamel remover according to the present invention is for removing enamel applied to a fingernail, a bottomed cylindrical container body with an upper opening, and a hole or notch that allows a finger to be inserted. A sponge body to be inserted into the container body in the state of being impregnated with the enamel removal liquid, and fixedly attached to the upper opening edge of the container body, and pressed against the outer circumferential portion of the upper surface of the sponge body A liquid leakage prevention member having an uneven portion, a ring body positioned below the liquid leakage prevention member and rotatably mounted on the outer peripheral surface of the container body, and a cap that covers the upper opening of the container body.

  In a preferred embodiment, the liquid leakage preventing member has a circumferential lip located inward from the inner wall surface of the container main body, and the uneven portion is provided at the lower end of the circumferential lip.

  In a further preferred embodiment, the container body includes a cylindrical upper region located on the upper opening side, and a lower region located below the upper region and having an internal cross-sectional area smaller than the internal cross-sectional area of the upper region.

  FIG. 1 shows an overall external view of a nail enamel remover 1 according to an embodiment of the present invention, and FIG. 3 shows a longitudinal sectional view thereof. FIG. 2 is a front view of the state where the cap is removed.

  The nail enamel remover 1 is for efficiently removing enamel such as manicure applied to the fingernails of the hand and pedicure applied to the toenails of the toes. As shown, a container body 10, a sponge body 20, a liquid leakage preventing member 30, a ring body 40, and a cap 50 are provided.

  4 and 5 show the container body 10. The container body 10 has a bottomed cylindrical shape with an upper opening. In a preferred embodiment, the container main body is formed by a cylindrical upper region 10A located on the upper opening side, and an inner cross-sectional area (a cross-sectional area surrounded by the inner wall surface) of the upper region 10A located below the upper region 10A. And a lower region 10B having a small internal cross-sectional area. As an example, the illustrated container body 10 includes a cylindrical upper region 10A and a tapered lower region 10B that is positioned below the upper region 10A and tapers toward the bottom.

  As shown in FIG. 4, the external thread part 11 is formed in the outer peripheral surface located in the boundary part of 10 A of upper areas of the container main body 10, and the lower area | region 10B. A plurality of position restricting ridges 12 are provided on the outer peripheral surface located slightly below the upper opening edge of the container body 10 and extend circumferentially at intervals.

  As shown in FIG. 5, eight protruding ribs 13 are provided on the inner wall surface of the lower region 10 </ b> B of the container body 10 at equal intervals in the circumferential direction. The rib 13 extends from the bottom end of the container body to the upper end of the lower region 10B, but is not formed in the upper region 10A.

  As shown in FIG. 9, the sponge body 20 has a substantially cylindrical shape as a whole, and a hole or notch that allows a finger to be inserted is provided at the center thereof. In the illustrated embodiment, the center hole 21 extends from the upper end surface to the lower end surface of the substantially cylindrical sponge body 20. In order to allow the finger insertion portion to expand in the radial direction when the finger is inserted, four notches 22 extending radially outward from the center hole 21 are provided.

  In a preferred embodiment, the substantially cylindrical sponge body 20 has a plurality of grooves 23 extending in the vertical direction on the outer surface thereof.

  The sponge body 20 is inserted into the container body 10 in a state of being impregnated with the enamel removal liquid. As shown in FIG. 12, the sponge body 20 has a height from the bottom end of the container body 10 to the vicinity of the upper end opening. As is apparent from FIG. 10 showing a cross section of the lower region 10B of the container body 10, the eight ribs 23 formed on the inner wall surface of the lower region 10B engage with the eight grooves of the sponge body 20. By this engagement, the inner wall surface of the lower region 10B of the container body 10 and the lower portion of the sponge body 20 rotate together without causing relative rotational deviation.

  As is clear from FIG. 11 showing a cross section of the upper region 10A of the container body 10, the inner wall surface of the upper region 10A is a smooth cylindrical surface having no ribs. The inner wall surface and the upper portion of the sponge body 20 are likely to cause relative rotational deviation.

  The cylindrical ring body 40 shown in FIGS. 2 and 3 is rotatably fitted on the outer peripheral surface of the upper region 10 </ b> A of the container body 10. The lower end of the ring body 40 is in contact with the stepped surface of the male threaded portion 11 of the container main body 10, and the upper end of the ring body 40 is in contact with the position restricting protrusion 12 of the container main body 10 or the upward movement is restricted. ing. Although not shown, the inner wall surface of the ring body 40 is provided with a recess through which the position regulating protrusion 12 of the container body 10 can pass. Therefore, if the recess (not shown) of the ring body 40 and the position regulating protrusion 12 of the container body 10 are aligned, the ring body 40 can be fitted onto the outer peripheral surface of the container body 10 from above.

  After the ring body 40 is mounted, the ring body 40 can freely rotate relative to the container body 10 between the stepped portion of the male screw portion 11 and the position regulating protrusion 12.

  As shown in FIGS. 3, 6, and 7, the liquid leakage preventing member 30 is a ring-shaped member having an inverted U-shaped cross section having a central opening 33, and is fixedly fitted to the upper opening edge of the container body 10. . The liquid leakage preventing member 30 is formed of a material having a sealing property, and prevents the enamel removal liquid from leaking outside even when the container body 10 is tilted.

  In the illustrated embodiment, the liquid leakage preventing member 30 has a shape that covers the position regulating protrusion 12 of the container body 10 in order to enhance the integrity with the container body 10.

  The liquid leakage preventing member 30 has a circumferential lip 31 that is located inward from the inner wall surface of the container body 10. The circumferential lip 31 hangs slightly downward and forms a gap with the inner wall surface of the container body 10. Therefore, the enamel removal liquid that has oozed out of the sponge body 20 when the container body 10 is tilted can be received in the gap.

  At the lower end portion of the circumferential lip 31 of the liquid leakage preventing member 30, a large number of concavo-convex portions 32 extending in a circumferential shape are provided. As shown in FIG. 3, the concavo-convex portion 32 of the circumferential lip 31 of the liquid leakage preventing member 30 is pressed against the outer circumferential portion of the upper surface of the sponge body 20 from above. Since the concavo-convex portion 32 engages with the upper surface of the sponge body 20 with the concavo-convex surface, relative slippage between the two is suppressed.

  The cap 50 shown in FIG. 8 closes the central opening 33 of the liquid leakage preventing member 30 when the nail enamel remover 1 is not used, and is screwed into the male screw portion 11 of the container body 10 on the inner wall surface thereof. An internal thread portion 51 is provided. As shown in FIG. 3, a sealing material 52 for securing a sealing property is fixedly attached to the back surface of the top wall of the cap 50.

  In the structure of the finished product shown in FIG. 3, the lower part of the sponge body 20 is compressed toward the center by the inner wall surface of the lower region 10 </ b> B of the container body 10 and the eight ribs 13. On the other hand, the upper portion of the sponge body 20 is also compressed toward the center by the inner wall surface of the upper region 10A of the container body 10, but the inner diameter of the upper region 10A of the container body 10 is larger than the lower region 10B, and Since no rib is formed in the upper region 10 </ b> A, the degree of compression is smaller than the lower part of the sponge body 20. In other words, the compression density of the sponge body 20 charged in the container body 10 is large in the lower region and small in the upper region.

  When removing the finger nail enamel of the thin hand using the above difference in compression density, the finger is inserted into the lower region of the container body 10 to remove the thick nail enamel. In doing so, a finger is inserted into the upper region of the container body 10. Since the toes are thick, after being inserted into the sponge body 20 having a small compression density, the sponge body 20 sufficiently increases the compression density by the toes and sufficiently exerts the enamel removal action.

  FIG. 12 exemplarily shows a state where the index fingernail 70 of the hand is inserted into the lower region 10 </ b> B of the container body 10. When removing the enamel of the nail 70 of the right index finger, for example, the ring body 40 is held so as not to rotate with the thumb and middle finger of the right hand, and the container body 20 is grasped and rotated with the left hand. Since the claw 70 is in a stationary state, the central hole 21 and the notch 22 of the sponge body 20 that rotates together with the container body 10 press and rub against the claw 70 to remove enamel.

  Since the upper surface of the sponge body 20 is engaged with the concavo-convex portion 32 of the liquid leakage preventing member 30 fixedly fitted to the upper opening edge of the container body 10 so as not to cause a relative rotational shift, the sponge body 20 is The container body 10 can be reliably rotated integrally with the entire vertical direction.

  FIG. 13 exemplarily shows a state in which the big toe nail 80 is inserted into the upper region 10 </ b> A of the container body 10. When removing the enamel of the toe claw 80, for example, the ring body 40 is held so as not to rotate with one hand, and the container body 10 is grasped and rotated with the other hand. Since the claw 80 is in a stationary state, the central hole 21 and the notch 22 of the sponge body 20 that rotates together with the container body 10 press and rub against the claw 80 to remove enamel.

  In the case of the illustrated embodiment, since four cuts 22 extending radially outward from the center hole 21 of the sponge body 20 are formed, the V-shaped protrusions located between the adjacent cuts 22 are on the nail. The enamel can be effectively removed.

  The embodiment described with reference to the drawings is an example illustrating the present invention by way of example, and various modifications and changes are possible. For example, the following changes can be considered.

  (1) The liquid leakage preventing member does not have to have a circumferential lip that is positioned inward from the inner wall surface of the container body. In this case, an uneven portion is provided at the lower end of the inner wall that hangs down along the inner wall surface of the container body without any gap.

  (2) The container main body may have a simple cylindrical shape having substantially the same diameter in the vertical direction without having the tapered lower region. In this case, typically, it may be used as a dedicated nail polish removal device for a fingernail or a dedicated pedicure removal device for a toe nail.

  (3) An important feature of the present invention is that the uneven portion of the liquid leakage preventing member is reliably engaged with the upper surface of the sponge body by the uneven surface so as not to cause a relative rotational shift. From this point of view, it is also included in the scope of the present invention that no groove is provided on the outer peripheral surface of the sponge body and no rib is provided on the inner wall surface of the container body.

  (4) The shape of the finger insertion opening of the sponge body can be arbitrarily selected.

  The above-described embodiments disclosed herein are illustrative in all respects and do not serve as a basis for limited interpretation. Therefore, the technical scope of the present invention is not interpreted only by the above-described embodiments, but is defined based on the description of the scope of claims. In addition, all modifications within the meaning and range equivalent to the description of the claims are included.

  The present invention can be advantageously used as a nail enamel remover having a simple structure.
