Patent Application
20230263277
The present invention belongs to the field of jewelry and and in particular to systems for attaching piercings and in particular to those of chip-type earrings.
The word “piercing” is used in the sense of jewelry and not in the sense of the act of piercing.
The word “hole” refers to an artificial hole made in the epidermis of an individual, obviously beforehand and perfectly healed, in order to place an ornament of the piercing type. We therefore understand by piercing a synonym of “jewel”, the jewel being configured to be able to be inserted into a hole in the skin.
Only piercings intended for full skin holes, without cartilage, are considered. Only holes in the form of a tunnel are considered, which have an entrance and an exit (arch, navel, earlobes, non-exhaustive list . . . ) to be opposed to the holes made for microdermal piercings, which have an entrance but no exit (neck, cheekbones, wrists . . . )
In the known state of the art, there are several ways to keep a piercing in position in a hole. It should be noted that the word “piercing” used without anatomical precision means any body location, while earlobe piercings are called earrings.
Regarding the subject matter of body piercings, it is worth mentioning in particular the types of ornament by the name of Labret, Barbell and Banane well known to a person skilled in the art. These three items are made up of a central rod, straight or curved, and two more voluminous and ornamental ends, at least one of which can be unscrewed and serves as a clasp. The two ends of the piercing, once it is in place, are on the surface of the skin while the rod passes through the hole.
The disadvantages of such systems are:
As far as ear piercings are concerned, we know several techniques for keeping an earring in position.
In the system of “ear chips” or nails—which are most commonly found—the ornamental part of the earring is placed on the front face of the lobe and is visible, while the part ensuring the holding the jewel remains concealed on the posterior face of the lobe.
The ornamental part is fixed on a rod which crosses the lobe by the hole and which receives a removable part called clasp. The latter slides on the rod by friction.
This clasp can be made of metal, silicone, rubber, and takes several forms and denominations in the known state of the art: butterflies, strollers, Alpa, stop .froufrou. . . .
The disadvantages of this type of system are known, in particular:
The international design patent WIP076529, dated Oct. 23, 2018, made by the owner of this patent application, describes a system of earring without clasp neither removable nor mechanical requiring force insertion from the flame side.
A difference in diameter between the rod and the flame allows the jewel to stay in place. However, this known solution has several drawbacks, three of which are notable: the first is due to the absence of a tip to guide the piercing and make it move through the thickness of the pierced skin.
The second is due to the inadequate dimensions of the flame: proportionally too large compared to the rod (which is adapted to the diameter of the hole), its passage in force causes pain. The third disadvantage is due to the lack of management of the relative weights of the pattern and the flame resulting in an unwanted imbalance of the jewel.
US 2010/122553 describes an example of a monolithic piercing intended to be inserted into a previously pierced skin hole of a user.
The present invention proposes to correct the defects of these prior art.
The aim of the present invention is to improve the closure systems for lightweight piercings and so-called “chip” earrings by producing a jewel that can be held in place without resorting to the presence of a mechanical or removable clasp, thanks in particular to the geometry of its shape as well as the elasticity of the skin.
Another object of the present invention consists in proposing a piercing device which is inexpensive to manufacture and provides an economical and elegant solution to the problem posed.
The device according to the invention makes it possible to achieve these objectives. It makes it possible to perform a monolithic piercing intended to be inserted into a previously pierced skin hole of a user, comprising:
In a particular embodiment of the invention, the ratio between the maximum perimeter PB of the bulb and the perimeter PT of the stem is between 1.3 and 2.1 and rather between 1.5 and 1.9 and preferably equal at 1.7.
Preferably, the tip 110 and the bulb 120 extend together in a first longitudinal direction L and the stem 200 extends in a second longitudinal direction L2. These two directions L1 and L2 can be either combined or distinct.
Other characteristics, object and advantages of the invention will appear on reading the description and the drawings below, given solely by way of non-limiting examples. In the accompanying drawings:
The preferred embodiments of the invention are now described and, for the sake of clarity and conciseness, we will first insist on the general characteristics of the solution being proposed (Section 1) which make it possible to solve the technical problem posed, before detailing further the preferred implementation (Section 2).
We will then focus on the use of the proposed piercing, which proves to be of obvious comfort during insertion, maintenance or removal (Section 3). Alternative embodiments will then be discussed (Section 4) as well as the advantages of the invention and considerations of industrial applications (Section 5). Finally, an exhaustive nomenclature will finally close the presentation (Section 6).
In general, section means any cross section made perpendicular to a longitudinal direction. A section has an area and a perimeter.
To avoid having to resort to any mechanical or removable clasp and to take advantage of the elasticity properties of the skin, the inventor proposes making a monolithic, rigid, non-deformable piercing 1, of unprecedented shape, which consists of four constituent elements illustrated in
The tip 110 has a cross-section of variable shape, preferably round or oval, configured to allow easy insertion of the piercing 1 thanks to the guidance and proper presentation of the bulb to the user's pierced hole. It extends along a first direction L1. Its length allows it to just come out the other side of the tunnel hole when the bulb begins to engage.
The bulb 120 has a cross section of variable shape but preferably round or oval. It looks like a bulge, for example ovoid, located between the tip 110 and the stem 200. The bulb extends in a direction LB which, in the embodiment of
Due to its geometry, the bulb concentrates the majority of the mass of the technical part. If its perimeter is invariably linked to the perimeter of the stem according to the relationship stated in the previous point, its length can vary so as to modify its weight. The latter, combined with that of the tip, counterbalances the weight of the pattern.
Depending on the size of the model, the bulb is stretched or compact, which gives it a more or less domed character. This aspect is represented by the value of the angles alpha and beta, which are measured from two tangents to the bulb, one on the tip side and the other on the stem side and from the two directions L1 and L2.
More specifically the angle α formed by the tangent to the bulb from any point of the first perimeter 410, located between the tip 110 and the bulb 120, and by a first longitudinal direction L1 corresponding to a longitudinal direction of the tip 110 —forms an obtuse angle greater than 135°. This a value illustrates the low slope of the bulb, on the tip side, which advantageously allows the skin of the hole to expand gently during insertion. This angle can vary from 135 to 180° depending on the different size configurations and model options.
More specifically, the angle β formed by the tangent to the bulb 120 from any point on the second perimeter 510, located between the bulb 120 and the stem 200, and by a second longitudinal direction L2—corresponding to a longitudinal direction of the stem 200—is between 90° and 180°. The value of 13 smoothens the slope of the obstacle constituted by the bulb for the epidermis of the hole during removal. Unlike insertion (where the tip travels through the hole to guide the bulb), during removal, it is the stem that serves as a guide for the bulb, and it is already in place. Thus, in use, the inventor noted that removing the piercing seemed easier than inserting it, which allows the small extreme value of β (90°) to be lower than that of α (135°). Advantageously, this smaller value of the angle β still allows painless removal of the piercing 1. As α, β may vary according to the configurations considered by the designer, while remaining within the ranges of values mentioned above.
The stem 200 has a cross-section of variable shape, preferably round or oval. Its profile is preferably cylindrical. It extends in a second direction L2. It is configured to adapt to the diameter and length of the “tunnel” hole in the user's skin. It measures between 3 and 15 mm depending on the anatomical situation of the hole.
The terminal part 300 materializes the ornamental pattern, which can be of various shapes provided that it has a volume and/or a characteristic dimension sufficient to prevent it from passing through the hole in the skin. The pattern creates the final stop which serves as a stop and marks the end of the insertion. The terminal part 300 must be both large enough not to pass through the drilled hole and small enough for its weight to be less than or equal to the combined weights of the tip 110 and the bulb 120, as described in point 48 below. Thus the 300 pattern is as minimalist as the 120 bulb.
The first three elements 110, 120 and 200 may advantageously result from a same manufacturing process and cooperate to achieve the functional technical part ensuring a triple function of insertion, holding in place and removal of the piercing 1.
In order for the jewel to hold in place in a harmonious and durable way, the mass of the motif must always be less than or equal to the sum of the masses of the tip and the bulb. Thus, an ideal placement of the pattern is obtained, which advantageously remains pressed against the skin.
The tip 110, the bulb 120 and the stem 200 each extend along the longitudinal directions L1, LB and L2. These three directions are preferably combined (Detailed in the variants)
Such a structural form has very advantageous physical and geometric characteristics. It results in a monolithic jewel that is inexpensive to manufacture, elegant and comfortable to wear, of great simplicity, whose technical part has a smooth and harmonious outline devoid of any acute angle. First, the tip 110 guides the progression of the jewel in the hole and allows the optimal presentation of the bulb 120 to the drilled hole of the user. Secondly, the bulb 120 causes thanks to its particular shape, for example ovoid, and at its widest perimeter a brief and controlled dilation of the epidermis, compatible with its elastic capacity, during the insertion and withdrawal phases. Thus the skin does not have time to be deformed and immediately resumes its usual shape around the stem 200. The bulb 120 also serves as a passive clasp by forming an abutment which retains the piercing 1 as soon as the latter is put in place. Finally, the pattern 300 not only serves as a terminal stop but also as a decoration, while advantageously counterbalancing the weights of the bulb 120 and the tip 110. Thus the piercing 1 rests harmoniously by its stem inside the hole, and its two ends, located on the surface of the skin, advantageously prevent it from escaping and balance the jewel.
In use, the inventor has noted that it is common for a user to have several holes of different diameters in the same anatomical area, in particular on the earlobe. The value of the diameter of the hole is revealed when trying on the jewel and cannot be guessed by eye. It is not possible to acquire a piercing with a diameter that is too small that you would quickly lose, or with a diameter that is too large and that would not fit into the hole. This is why the invention described here is envisaged in several sizes, for example 6 distinct sizes. Size numbering is based on stem diameter.
The increase in the diameter of the stem from one size to another is done in increments of 0.1 mm. It is the extent of the choice of sizes that makes the model complex although the shape of its outline is very simple. Thus the shape of each model evolves subtly from size to size and all 6 sizes of the same model give a series. The shape variations are governed by mathematical rules establishing a continuous solution for each series. From one size to another, the largest perimeter of the bulb increases in proportion to the perimeter of the stem, and this, whatever the embodiments, so as to respect the ratio PB/PT=1.7. On the other hand, the other dimensions may undergo slight variations, homothetic or not, to meet design or weight requirements in order to advantageously control the decorative aspect and production costs.
When all its dimensions increase proportionally with the diameter of the stem, piercing 1 undergoes a homothetic increase. All its dimensions, a fortiori those of the pattern, are increasingly large, which advantageously increases the possibilities in terms of design of the pattern. However, the overall weight of piercing 1 increases, which affects the cost of raw material and leads to a great disparity in the prices per piece.
When the lengths of the bulb 120 and the tip 110 vary inversely proportional to the perimeter of the stem 200 (thanks to a moderating coefficient) a series of piercings 1 is obtained within which the shape of the technical part changes by one size to another. Firstly, the more the perimeter of the elements of the technical part increases, the more their length decreases, so the technical part is more and more compact from size to size, which gives new shapes. Secondly, as the weight of the bulb 120 and of the tip 110 increases slowly, the volume of the patterns changes very little from one size to another, which can be advantageous with respect to aesthetics (for example accumulation of the same patterns on an ear with different hole diameters). Thirdly, by restricting the lengths, and therefore the weights, we advantageously reduce the costs of raw materials and we can offer a single price for all the piercings 1 of the same series (except if they are set with precious stones, to which case the cost of the gem takes precedence over the cost of the weight of metal).
There are other series with a length of 120 bulb and 110 tip that remain constant when piercing 1 changes in size. These are intermediate series between the two previous ones, series where the 300 pattern grows moderately.
There are other series where the tip 110 is tapered. This version is detailed in the section “alternative embodiment, variant at the tip”.
Preferably the piercing is an earring.
Preferably the piercing 1 is rigid.
The preferred embodiment is particularly illustrated in
It is the first end of the POP piercing. It itself has, as can be seen in
Advantageously according to the preferred embodiment, the tip 110 is cylindrical, of constant perimeter PP equal to 0.9 to 1.3 times that of the stem 200, but preferably equal to 1.1, and its length measures 2 mm to 5 mm. Slightly increasing the diameter of the tip makes it heavier (without the user feeling it during insertion) and consequently increases the volume of the pattern and the design possibilities.
It has two ends, namely a first end 410 having a first perimeter on the tip side 110 and a second end 510 having a second perimeter on the stem side 200 and extends in a direction LB. It has an ovoid profile and, according to the preferred embodiment, an advantageously oval section in order to present two zones suitable for marking the logotype of the brand.
Any perimeter of bulb 120 is greater than any perimeter PP of tip 110 and any perimeter PT of stem 200. The bulb 120 has among its many perimeters, a maximum perimeter denoted PB. The ratio between the maximum perimeter PB of the bulb 120 and any perimeter PT of the stem 200 is between 1.3 and 2.2, rather between 1.5 and 1.9 and preferably equal to 1.7.
At the first end of the bulb 120 there is an angle α which is the angle formed by a tangent to the bulb 120 at any point of its perimeter 410 and by the first longitudinal direction L1. Preferably, according to the preferred embodiment, the angle α is an obtuse angle, between 135° and 180°, preferably between 160 and 170° and preferably equal to 165°.
At the second end of the bulb 120 there is an angle β, which is the angle formed by a tangent to the bulb 120 at any point of the second perimeter 510 and by the second longitudinal direction L2. Preferably, according to the preferred embodiment, the angle β is an obtuse angle, between 90° and 150° and preferably between 115° and 125° and preferably equal to 120°.
According to this POP mode, the direction LB of the bulb 120 coincides with the first longitudinal direction L1
The stem or rod 200 is located between the bulb 120 and the pattern 300. Its first end is the second perimeter 510 and its second end is the pattern 300.
Advantageously according to the preferred embodiment, it is cylindrical and its diameter determines the designation of the sizes of the model.
The stem 200 extends in a second longitudinal direction denoted L2. Preferably in the preferred embodiment, L2 coincides with the first direction L1 of the tip, itself coincides with the direction LB of the bulb 120.
The length of the stem 200 is adapted to the length of the user's “tunnel” hole. For the lobe of an ear, its length varies between 3 and 6 mm. Preferably, the rod can have several predefined values depending on the location of the piercing on the ear and the age of the user.
It is located at the second end of the stem 200.
It is an ornamental part which can take any form provided that its volume is sufficient and/or at least one of its characteristic dimensions is sufficient to prevent it from passing through the hole. In this preferred embodiment, the weight of the pattern is equal to that of the cumulative weight of the tip 110 and the bulb 120 with a tolerance of 10%.
Thus according to the POP mode, preferred embodiment, the tip and the stem are cylindrical, the tip has a diameter slightly greater than that of the stem, the bulb is oval without a flat, α and β are equal to 165° and 120° and the three directions L1, LB and L2 are identical: all the parts are aligned and the piercing is straight as a whole. The jewel, which is an earring, is held horizontally in a harmonious and durable way thanks to the equal weight of its ends.
Most often, the user has no idea of the diameter of his hole. It's best to try a size small first. It goes without saying that the artificial hole must be perfectly healed. It is recommended to moisten the hole with water or an antiseptic solution. Opportunity, we can use a tester as described in the “accessories” section below.
With one hand, the user inserts the piercing 1 through the tip 110 while firmly holding the surrounding skin with the other hand. In the case of the earlobe, it is helpful to pull the lobe down and back so as to stretch the skin and cause the hole to open slightly. When you feel the end 111 of the tip 110 on the other side of the lobe, the insertion is very good.
Advantageously, the tip 110 serves as a guide so as to allow proper engagement of the expansion bulb 200 in the hole.
Advantageously, the value of the angle α allows painless insertion of piercing 1 thanks to a very gradual dilation of the skin.
The user increases the pressure of his fingers on the pattern 300 to pass the largest perimeter of the bulb 120 slightly forcefully through the hole thanks to the elasticity of the skin. It is necessary to force a little, without causing pain, and this is left to the appreciation of each one. The epidermis expands as the bulb 120 passes, then immediately tightens around the stem 200.
Although the sensation that the bulb 120 has passed is clear, it is preferable to check, by bending the lobe, that the bulb 120 has fully emerged on the other side and is playing its role as a non-return stop. Once in place, you have to pull on the 300 motif to test the hold of the jewel. If piercing 1 comes out easily, repeat the procedure with the larger size. Piercing 1 should resist removal to some extent.
The relative perimeters of the bulb 120 and the stem 200 have been particularly studied to respect the elastic capacity of the epidermis. This stems from the elongation capacity of a protein: elastin. It is the volume of the bulb 120 which determines the choice of the size of the piercing: if the bulb does not pass, the user must return to the size below.
Once the piercing [1] is in place, it rests in the hole by its stem 200. The bulb 120 and the pattern 300 each constitute, on either side of the hole, a sufficient volume to prevent the piercing 1 from escaping.
Advantageously, the value of the difference between the perimeters PB of the bulb 120 and PT of the stem 200 creates a stop that is both sufficient to oppose a passive resistance to the fall of the jewel during the natural movements of the user and compatible with the withdrawal asset of the jewel according to the will of its wearer.
Thus, the piercing 1 once in place is maintained by its shape as well as by the elasticity of the skin, without adding any moving or removable part. Thus, due to its structural shape, the jewel can be held in place without the use of any clasp.
To remove the piercing 1, the user pulls on the pattern or pushes on the end 111 of the tip 110 while firmly holding the surrounding skin. Advantageously, the surrounding skin can be moistened. The epidermis distends to overcome the stop in the opposite direction to the insertion explained above and let the bulb 120 pass.
Advantageously the stem 200 serves as a guide for the engagement of the bulb 120 in the hole during removal, and the latter is easier than insertion.
Advantageously, the value of the angle β allows painless removal of the piercing 1 thanks to a sufficiently gradual dilation of the skin.
Alternative embodiments may be considered according to various adjustments and characteristics below, which authorizes multiple versions and many and various forms. Other shapes may be considered without limiting the subject of this patent application.
The following variants can be associated with each other.
In another embodiment illustrated in
It is in the form of a truncated cone having perimeter 111 as its first end and perimeter 410 as its second end located at the junction between said tip 110 and bulb 120. The perimeter value 111 is greater than or equal to 0.8 mm. The value of the remarkable perimeter 410 is greater than the value of the first perimeter 111 and determines the taper. However, any perimeter PP of the tip always remains less than any perimeter PB of the bulb.
The tip 110 extends in a first longitudinal direction L1.
With its two ends of different perimeter, the tip 110 has a taper varying between 2% and 30% depending on the embodiment and the size of the piercing. The conicity is constant in a homothetic series and variable in a series whose bulb and tip lengths are restrained by a moderating coefficient. (
The angle α is the angle formed by a tangent to the bulb at any point of its perimeter 410 and by the first longitudinal direction L1. It is variable in a series whose point has a variable taper, its value is between 155 and 180° and tends towards 180° in the large sizes of this series.
In another embodiment, the bulb 120 has 1 or 2 flats 121, as shown in
The largest perimeter PB of the bulb 120 of the piercing carried out according to this alternative mode nevertheless respects the characteristic according to which the ratio between the maximum perimeter PB of the bulb 120 with flats 121 and the perimeter PT of the rod 200 is between 1.3 and 2.1 and rather between 1.5 and 1.9 and preferably equal to 1.7.
These flats can advantageously accommodate the hallmark and/or the brand logotype.
In another embodiment, illustrated in
In another embodiment, the stem appears with a curvature (
We will now describe a specific embodiment, designated as piercing #2. This piercing is monolithic and rigid, non-deformable, without mechanism, made in one piece and without any removable part. This piercing model is advantageously an earring.
Piercing #2 consists of a tip 1100, a bulb 1200, a stem 2000 and a ending pattern 3000. Piercing 2 has certain characteristics that differentiate it from piercing 1, described previously: the shape of its bulb 1200 is so elongated that it merges at its two ends with the tip 1100 and the stem 2000 thus the two angles α and β tend around 180°, and the mass of the ends on either side of the stem 2000 has a clear difference, namely that the mass of the pattern is lower than that of the bulb and the tip combined.
The tip 1100 of piercing #2 has a conical profile and a round or oval section in accordance with the diameter of the user's pierced hole. It extends along a first direction denoted L1100.
The tip 1100 is configured to allow easy insertion of piercing 2 thanks to the guidance and proper presentation of the bulb to the user's pierced hole. Its length allows it to just come out the other side of the tunnel hole when the bulb begins to engage.
Any perimeter of Pointe 1100 is denoted PP. Two of these perimeters are however noteworthy: the perimeter of its free end 1110 and the perimeter of its other end, which joins the bulb 1200 and which is called the first perimeter 4100. The perimeter 1110 is the smallest of the 1100 tip perimeters and is equal to that of the stem 2000 with a 10% tolerance. Any perimeter PP of the tip 1100 is less than any perimeter PB of the bulb 1200.
The bulb 1200 has an oblong profile, and a round or oval section. It extends in a second direction noted L1200.
The bulb is configured to cause a beneficially gradual and painless dilation of the epidermis during insertion and removal. Its first end, at the tip side 1200, corresponds to the first perimeter 4100. Its second end joins stem 2000, and the perimeter of this second end is called second perimeter 5100. Any PB perimeter of the bulb is greater than any PP perimeter of the tip 1100 and any PT perimeter of the stem 2000.
The bulb 1200 has a multitude of different perimeters of which only one is maximum. The largest perimeter PB of the bulb 1200 of the FUN piercing made according to this specific mode respects the following characteristic in which the ratio between the maximum perimeter PB of the bulb 1200 and the perimeter PT of the rod 2000 is between 1.3 and 2.1 and rather between 1.5 and 1.9 and preferably equal to 1.7.
The section of the bulb increases slowly from the value of the perimeter 4100 on the tip side 1100, until its perimeter reaches the value PB of the maximum perimeter, then decreases slowly until it reaches the value of the perimeter 5100 on the stem side 2000.
The stem 2000 has a cylindrical profile and a round or oval section. It extends in a third direction noted L2000. Its length is equivalent to the thickness of the pierced skin.
Any perimeter PT of the stem 2000 is less than any perimeter PB of the bulb 1200. The value of the perimeter PT of the stem 2000 determines the maximum perimeter of the bulb PB according to the ratio defined in point 121.
The stem 2000 is the support of the piercing when it is in place. The epidermis of the drilled hole tightened around it after being briefly stretched by the passage of bulb 1200 during insertion. Stem 2000 guides bulb 1200 during removal.
The end part 3000 supports the ornamental pattern, which can be of various shapes provided that it has a volume and/or a characteristic dimension sufficient to prevent it from passing through the hole in the skin. The pattern creates the final stop which serves as a stop and marks the end of the insertion.
The 3 directions L1100, L1200 and L2000 are curved and link together harmoniously without breaking.
The angle α is G angle formed by the tangent to the bulb 1200 from any point of the first perimeter 4100 and by the first longitudinal direction L1100.
The angle β is the angle formed by the tangent to the bulb from any point of the second perimeter 5100 and by the third longitudinal direction L2000.
In a preferred embodiment of the piercing #2, the two angles tend towards 180° and these values allow a harmonious continuity at the level of the surfaces of the tip 1100 to the bulb 1200 and of the bulb 1200 to the stem 2000.
Thus the tip 1100, the bulb 1200 and the stem 2000 of the piercing #2 merge into one another to give a piece of jewelry having a continuous profile (without marked variation in volume, without visible change in the inclination of the surfaces, or without a break in the alignment of the tangents or without apparent demarcation). The distinction of the 4 parts is made during the design of the 3D model and is not obvious to the eye.
Stretching the bulb 1200 increases its mass significantly. The bulb 1200 of piercing #2 is 1.5 to 3 times heavier than the pattern 3000. This difference in weight on either side of the stem 2000 causes a vertical rocking of the piercing #2 around the stem 2000 and its particular placement in space, the bulb 1200 pulling downwards and/or the rear causing the 3000 pattern that fits perfectly on the lobe. Gravity keeps piercing #2 in this same position permanently. The weight of the bulb is advantageously used to retain the piercing 2. The larger PB perimeter of the 1200 bulb is an additional security so that the piercing 2 does not escape during exceptional movements of the user.
On the other hand, the bulb 1200 of piercing 2 is clearly visible thanks to its length and its perimeter. It protrudes behind the lobe and presents itself advantageously as an ornamental element in its own right.
Model #2 is, like piercing #1, available in sizes so that each user can find a model exactly suited to the diameter of their pierced hole.
All the piercings complying with model #1 or model #2 have their size calculated and named with reference to their stem 200 or stem 2000 diameter. The perimeter of the bulbs 120 or 1200 is calculated in relation to the perimeter of the stems 200 or 2000.
The sizes defined for all piercings 1 and all piercings 2 are the same. For example, size 2 of a piercing #1 corresponds to size 2 of a piercing #2 . . . The size testers can be used for piercings #1 and piercings #2 indifferently.
Piercing #1 is a millimetric object. Made entirely of 24-carat platinum, for example, the toughest and most dense biocompatible material available to us, this jewel, in its largest size, weighs around 1 g.
Piercing #2 is 2 to 5 cm high depending on size and model and can weigh up to 3 g.
Due to its rigid, non-deformable monolithic shape, this jewel is indestructible, with no removable or mechanical clasp.
Due to the absence of an acute angle and/or clasp, cleaning the jewel, even in place, is easy and efficient and bacterial deposits are reduced to a minimum.
Due to its smallness and lightness, the jewel is completely forgotten by the user, which makes it exceptionally comfortable.
Due to its sobriety, the technical part of the jewel is an ornamental element in its own right which can be advantageously visible.
In addition, this piercing can be made from multiple materials, and by means of a manufacturing process of the most economical.
Piercing #1 and piercing #2 can be made of metal and/or alloy of metals, precious and non-precious, but also of ceramic, glass, crystal, horn, bone or any sufficiently tenacious and bio-compatible material.
Preferably piercing #1 and/or piercing #2 are made of a single material. However, different materials can be used for each of the tip, bulb, stem and pattern parts.
Pattern 300 of piercing #1 and/or pattern 3000 of piercing #2 may include a cosmetic inlay: lacquer, mother-of-pearl, precious stone or imitation . . . which may be, in a non-exhaustive manner, crimped or glued.
The piercing [1] or the FUN piercing can be cast, machined or printed as a whole. They can also be assembled with parts from different manufacturing methods.
A set of size testers (
Currently there are two testers for 6 piercing sizes. One tester works for 3 consecutive sizes. There is one for sizes 00, 0 and 1 and another for sizes 2, 3 and 4.
A size tester results from the juxtaposition of 3 piercings #1 according to the preferred embodiment, without their stem or their pattern. Only tips and bulbs are juxtaposed and aligned in ascending order of their size. At the end of the biggest of the three bulbs is a gripping plate on which the numbers of the sizes are engraved in a clearly visible way.
The user begins by inserting the smallest tester by the tip, holding it by the grip plate. If the first bulb (size 00) passes through the hole without difficulty, he must continue to thread the tester and pass the next bulb. The size of the ideal piercing is determined by the bulb preceding the one that cannot pass. For example: the 3rd bulb (corresponding to a size 1 piercing) of the small tester does not pass through the drilled hole. The pierced hole can therefore receive a piercing of the size of the second bulb, corresponding to a size 0. For example, if the 3 bulbs of the small tester pass easily through the drilled hole, then you must try the second tester which is larger and repeat the operation.
