Abstract

The invention relates to a monolithic piercing (1) designed to be inserted in a previously pierced hole in the skin of a user, the piercing comprising: •—a tip (110), configured to allow guiding and suitable presentation of an expansion bulb during its insertion into the hole in the skin; •—the expansion bulb, (120), having an ovoid profile and variable cross-section having a plurality of different perimeters, only one of which is maximum, the bulb (120) being configured to ensure a gradual and painless expansion of the skin during guiding of the piercing into the hole; •—a rod (200) configured to adapt to the tunnel hole of the skin and enabling support of the piercing; •—an end portion (300) consisting of an ornamental relief, which has a volume and/or a characteristic dimension that is sufficiently large to prevent the piercing from passing through the hole in the skin; and •—wherein the tip (110), the bulb (120) and the rod (200) cooperate in order to ensure a triple function of insertion, holding in place and removal of the piercing allowed by the guiding and expansion of the hole; •—wherein the perimeter PB of any cross-section of the bulb (120) is greater than the perimeter PP of any cross-section of the tip (110) and than the perimeter PT of any cross-section of the rod (200); and •—wherein the weight of the ornamental end portion (300) is less than or equal to the combined weight of the tip (110) and the bulb (120).

Dependent claims

A monolithic piercing (1), intended to be inserted into a previously pierced hole in the skin of a user, the piercing comprising:

a tip (110), configured to allow guidance and suitable presentation of a bulb of dilation upon insertion into said skin hole;
a dilation bulb (120), having an ovoid profile, of cross-section of variable shape, having several different perimeters of which only one is maximum, said bulb (120) being configured to ensure a progressive and painless dilation of the skin during guiding piercing in the hole;
a stem (200) configured to match the length and diameter of the skin tunnel hole and provide support for the piercing;
and
an ornamental end portion (300) constituting an ornamental pattern having a sufficiently large volume and/or characteristic dimension to prevent the piercing from passing through the skin hole;
wherein the tip (110), the bulb (120) and the stem (200) cooperate to ensure a triple function of insertion, holding in place and removal of the piercing permitted by the guidance and the dilation of the hole;
and
wherein the perimeter PB of any cross section of the bulb (120) is greater than the perimeter PP of any cross section of the tip (110) and the perimeter PT of any cross section of the stem (200);
and
wherein the weight of the ornamental end portion (300) is equal, with a 10% tolerance, to the combined weight of the tip (110) and the bulb (120);
and
wherein the ratio between the maximum perimeter PB of the bulb (120) and any perimeter PT of the stem (200) is between 1.3 and 2.1 and rather between 1.5 and 1.9 and preferably equal to 1.7;
and
wherein the angle α formed by the tangent to the bulb (120) from any point of the first remarkable perimeter (410), located between the tip (110) and the bulb (120), and by the first longitudinal direction L1 of the tip (110) is between 135° and 180°;
and
wherein the angle β formed by the tangent to the bulb (120) from any point of the second remarkable perimeter (510), located between the bulb (120) and the stem (200), and by the first direction longitudinal L1 of the tip (110) is between 90° and 135°.

A monolithic and rigid (FUN) piercing, made in one piece, without any removable part, without mechanism, intended to be inserted into a previously pierced skin hole of a user, the piercing comprising:

a tip (1100), configured to allow proper guidance and presentation of a dilatation bulb during insertion into said skin hole;
a dilation bulb (1200), having an oblong profile, of cross-section of variable shape, having several different perimeters of which only one is maximum, said bulb (1200) being configured to ensure a progressive and painless dilation of the skin during guiding piercing in the hole;
a stem (2000) configured to match the length and diameter of the skin tunnel hole and provide support for the piercing;
and
an ornamental end portion (3000) constituting an ornamental pattern having a volume and/or a characteristic dimension large enough to prevent the piercing from passing through the skin hole;
and
wherein the tip (1100), the bulb (1200) and the stem (2000) cooperate to ensure a triple function of insertion, holding in place and removal of the piercing permitted by the guidance and the dilation of the hole;
and
wherein the perimeter PB of any cross section of the bulb (1200) is greater than the perimeter PP of any cross section of the tip (1100) and the perimeter PT of any cross section of the stem (2000);
and
wherein the weight of the ornamental end portion (3000) is 1.5 to 3 times less than the combined weight of the tip (1100) and the bulb (1200);
and
wherein the ratio between the maximum perimeter PB of the bulb (1200) and any perimeter PT of the stem (2000) is between 1.3 and 2.1;
and
wherein the angle α formed by the tangent to the bulb (1200) from any point of the first remarkable perimeter (4100), located between the point (1100) and the bulb (1200), and by the first direction longitudinal L1100 of the tip (1100) tends towards 180°;
and
wherein the angle β formed by the tangent to the bulb (1200) from any point of the second remarkable perimeter (5100), located between the bulb (1200) and the stem (2000), and by the third direction longitudinal L2000 of the stem (2000) tends towards 180°.
