Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel bag-based method for forming pearls.

Traditionally, artificial pearls have been cultured using pearl oysters and other oysters as mother oysters, but in recent years, a method of culturing pearls using abalone as a mother oyster has also been known.

The color and luster of abalone shells make it possible to make pearls with the same excellent color and luster.

The present inventor has been researching the pearl forming method using a bag.
After repeated development, he first applied for a patent (patent application 1983-1983)
, No. 115). The bag is a single shell, and if the nucleus is inserted into the muscles or internal organs, which are attached to rocks in living Shanghai to protect themselves from external enemies, they will be subjected to strong pressure due to the contraction of the shell, and the internal organs will be damaged. However, according to the previous invention, the abalone that has been nucleated is housed in a cylinder without being able to escape, and cultured in seawater to prevent such pressure and damage to internal organs. Pearls of excellent quality can now be obtained.

In this method, when inserting the nucleus into the mantle, the mantle is incised at approximately the center, and the nucleus and the mantle piece taken from another bag are connected with nylon threads to remove the mantle. Then, a hole was drilled in the shell, the nylon thread was pulled out from the hole, and it was tied and fixed to the convex part on the outside of the shell. The mantle piece is generally called a piece, and it later comes into contact with the nucleus and is cultured as a molten swarm, which serves to supply the pearl coat to the nucleus.

However, in this type of enucleation, the central part of the mantle membrane is incised, which causes severe damage to this membrane, allowing bacteria to enter through this incision, making it difficult for the incision wound to fully heal. Furthermore, even if the nucleus is fixed inside the mantle, it is not possible to stably position the nucleus in a fixed position, making it difficult to form a perfectly round pearl.

Thus, the present invention provides a method for efficiently forming pearls by inserting and stably fixing the nucleus into the mantle membrane without damaging the mantle membrane when forming pearls using abalone as a mother oyster. The purpose is to.

According to the present inventor, the purpose is to make a hole in the mantle of the abalone at the attachment part where the mantle is attached to the shell edge, and insert a piece of the mantle taken from another bag into the mantle.

It has been found that this can be achieved by a method characterized by firmly contacting and fixing the mantle piece to the inside of the shell edge attachment part through the mantle piece.

The method of the present invention will be explained in detail with reference to the drawings. A hole 3 is made in the mantle 2 at a part attached to a shell edge 1 formed in a flat shape with a certain width at the peripheral edge of an abalone shell. The size of the hole drilled in the mantle 2 at this attachment point should be approximately 0.5 mm, and the hole should be inserted shallowly and diagonally so as not to damage the internal organs 4 such as the liver that are in contact with the mantle. At the same time as drilling hole 3, pass the Chiron Tengunu 5, which has a diameter of 0.3van and a length of about 40cm, through the hole. Furthermore, the tengunu 4 is pulled out to the outside through the middle between the inside of the shell and the mantle at the corresponding position.

11 indicates muscle.

The piece 6 and the core 7 are attached to the tip of the nylon thread 5 pulled out to the outside. Piece 6 is a piece of mantle taken from another bag as described above, and for a normal-sized nucleus, a piece of about 5 sulfur angles is suitable. This is an average of 12C
In seawater, it melts in about two weeks and forms nacre. Further, as the nucleus 7, any pearl nucleus used in normal pearl culture can be used, but recently, freshwater brown oyster shells shaped into a spherical shape are well known.

As for the thickness, for example, a core of about 10 cYn diameter for a bag of 13 to 15 crn, and about 11 m for a plane of 16 to 18 m.
A core of diameter is used. When trying to obtain large pearls in a short period of time, a very large nucleus is used.

Drill a hole in the center of the piece 6 and the core 7 respectively, pass the nylon thread pulled out to the outside of the shell through the Oz piece and then through the core 7, then apply, for example, a leanoacrylate-based instant adhesive and let it dry. Then, the nucleus 7 is adhesively fixed to the nylon thread 5. The nylon thread 5, which has been pulled out and connected to the bead 76 and the nucleus 7, is pulled in the opposite direction to the inside of the pulled shell and the mantle, and reaches the shell edge attachment part that was previously drilled. A nylon thread 5 is pulled on the outside 8 of the shell and ties its tip into a hole 9 at the end, while near the perforated shell edge attachment a cemedine (
The core 6 and the piece 7 are tightly fixed to the outside of the shell with an adhesive 10 such as (Trade name) or underwater epoxy, and in this way the nucleus 6 and the piece 7 are brought into strong contact with the attachment part of the mantle 2 and the shell edge 1 inside the mantle. . At this time, as shown in the cross-sectional view of Fig. 4, the nucleus 7 is brought into strong contact with the attachment part of the shell edge 1 via the piece 6, and the pearl is cultivated for a long period of time in seawater while suspended in the membrane. It makes you feel it. Cultivation in seawater is carried out by placing an appropriate number of planers with kernels in them in a basket along with seaweed such as kelp, which is used as a staple food, and suspending the cage in seawater.

If they are reproducing naturally.

It lives in a state in which the figure in FIG. 4 is vertical, that is, in a state in which the muscle 11 is attached to a rock or the like in seawater.

The present invention relates to such a configuration, and since the mantle membrane at the part where the shell edge is attached is not perforated and the relatively weak central mantle membrane is not incised, damage to the mantle membrane and invasion of bacteria can be well prevented. can. The mantle of the shell edge attached to the shell is more muscular than that of other parts, and the nucleus is in strong contact with the mantle of the shell edge attachment, suspended in the visceral space of the shellfish. Because it is held in this state, it is affected by the movement of the mother shell's muscles.The nucleus adheres to the mantle through the piece and is held in a stable state inside the shell edge.

It is fixed and can effectively prevent pressure from internal organs, damage to them, and outer shell of the mother shell.

In addition, at this shell edge attachment part, a piece of mantle is sandwiched between the nucleus and the mother mollusk and is tightly attached to each other, so the piece gradually melts as it receives the mother oyster's body temperature, forming a pearl on the surface of the nucleus. A film is formed sequentially, and on top of this film, secretion from the mother oyster mantle and the formation of a migration film of nacre can be seen, and the thickness of the nacreous film on the surface of the nucleus gradually increases, resulting in good luster and color. This makes it possible to efficiently produce high-quality pearls that are more perfectly round. In the previous invention, a cylinder was used and the work was complicated, but in the present invention, such a cylinder is not necessary and the work is simple.

Specific examples of the present invention are listed below.

Example: 0.0% on the mantle at the edge of the shell of a rainbow abalone of size 15/1771.
A 5-strip hole is made, a nylon tenges with a diameter of 0.3 mm and a length of 40 cm is passed through the hole, and the hole is extended outwardly from the edge of the shell at the opposite portion. On the other hand, a hole was made in the center of a 5-square mantle piece taken from another bag and a 10-diameter nucleus made from a brown sea mollusk, and the nylon tenges described above was passed through these holes one after another. Cyanoacrylate instant adhesive was applied to the tip of the Tenges, the nucleus was inserted there, and it was dried and fixed with adhesive. □ Pull the nylon thread connecting the piece and the nucleus to insert the piece and nucleus into the mantle and inside, pull the other end of the nylon thread to the outside of the shell, tie it to the hole in the shell, and secure it near the edge of the shell. used adhesive to adhere nylon thread to the shell. In this way, the nucleus was firmly contacted and fixed inside the shell edge through the piece.

After the kernels had been placed in this way, the bags or individuals were placed in a basket with kelp and suspended in seawater, where they were raised for about a year. After culturing in this manner, the pearls were taken out and a perfectly round pearl with a diameter of about 11 was obtained. All 20 pieces were of good quality, with excellent color and gloss, and no alignment.
