| Claims 1. The capsule for coin storage and examination - the "Slab", comprises a body, an upper insert, a lower insert and a cover, the capsule made of a transparent material in the form of the body and the cover being joined by ultrasonic welding. 2. The shape of the "Slab", the capsule for coin storage and examination, constitutes a cylinder with truncated pyramids adjoining from above and below (Figure 7). In the two-dimensional plane it looks like a circle with trapezoids connected thereto ((Figure 2). Thus, parts of the circle not held by trapezoids provide overview of the flank of the fixed coin known as the rim. 3. Accordingly, the upper and the lower parts of the body are shaped as truncated pyramids (Figure 1). These parts of the body will also contain unique identification information about the coin, as well as its description and certification information. 4. Inserts (Figure 3 and Figure 4) act as coin holders and have a 30 to 60 degree bevel depending on a shape and size of a coin. The shape of the holder corresponds to the shape of the body at the point of contact of the holder with the body, and it has the shape of a small truncated pyramid at the point of contact of the holder insert with the coin. At the same time, the number of small truncated pyramid-shaped holders at the area of contact of the insert with the coin is not limited and must be more than two in total for all inserts. (Figure 3 and Figure 4 represent 4 holders in total) 5. The method of coin fastening: The coin is fixed inside small slits in upper parts of small truncated pyramid-shaped holders. At the same time, the number of small truncated pyramid-shaped holders at the area of contact of the insert with the coin is not limited and must be more than two in total for all inserts. (Figure 3 and Figure 4 represent 4 holders in total) 6. The "Slab" capsule also has a protective skirting along the whole surface of the capsule. |
Title of the invention
CAPSULE FOR STORAGE AND EXAM INATION OF A COIN
Field of the invention
The present invention relates to devices for coin collection storage.
Background of the invention
Devices for coin and medal storage and examination are known in the prior art (see Patent RU No.2113159, ΜΠΚ 6 A47G 1/12 of February 25, 1997).
The devices for storage and examination of a coin or medal comprise a body with cover, which is connected to the latter using linking parts with a possibility of compulsory disjunction, and a slot for placement of a coin, which is located on the inner surface of the bottom part of the body or cover and formed by protrusions or a single protrusion with formation of a free section of the surface. The free section of the surface is limited by the wall surface of a single protrusion or surfaces of a plurality of protrusions, which match the diameter of the coin or medal. The body and the cover are made of a transparent material. The device provides ease of use with simpler structure.
A module for coin and medal storage and examination is also known in the prior art (see Patent RU No.2537279, ΜΠΚ A47G 1/12 of 09.04.2010).
The module relates to devices for storage of collectible items and, more particularly, relates to a flat holder, with an aperture where a transparent detachable capsule with a cavity for storage and examination of coins or medals is fixed. The module comprises a detachable flat capsule made of a transparent material in the form of a body and a cover interlinked with each other, fixed in the aperture of the flat holder and fixed in relation to it using protrusions on their outer surfaces along the perimeter of each of them. Each capsule is equipped with a separate holder having square outer shape.
These devices differ from the present invention fundamentally, since the goal of coin encapsulation is not only their preservation, but also their identification and storage without the need of removal from the rigid and convenient capsule (Slab). After the coin is placed inside the capsule, the cover of the slab is sealed and removal of the coin therefrom without damaging the capsule is not possible, unlike abovementioned devices. Rectangular slabs for coin storage intended for both coin preservation and identification are also known in the prior art. These capsules constitute a transparent rectangular plastic container and are made of a material which guarantees coin preservation; capsules are sealed after coins have been placed inside.
Therewith, known devices and methods of collector coin storage have a number of disadvantages: they do not provide a possibility of examination of coins from all sides (coin rim is not visible), and have limitations for storage of coins with irregular shapes.
These disadvantages are caused by the shape of the holder having rectangular shape with a recess for coin placement in the middle, which limits overview of the coin.
Unlike those capsules the proposed "Slab" device, while retaining all abovementioned functions, provides a better overview of the encapsulated coin, while reducing requirements to shapes of coins subject to encapsulation.
Disclosure of the invention
The use of the invention and the capsule makes it possible to achieve the following goals:
1. Almost complete isolation of the coin from the environment, preventing its mechanical damage, including severe oxidization.
2. Guarantee of coin authenticity, its identification.
3. Expert opinion regarding the state of the coin (by Sheldon scale).
Apart from that, the task of the invention is to provide a possibility of a 100% overview of a collector coin, including examination of the rim of the coin. A unique shape of the capsule provides the solution for this task.
Coin holders are designed to allow encapsulation of any coins, including those having flaws, rough edges, irregular shape etc., as well as coins of various sizes and diameters.
Additionally, the shape of the capsule provides for a possibility to indicate identification information for the collector coin in the upper part of the body, allowing easy identification and appraisal of it without any special knowledge.

Fig. 3 is a representation of a three-view diagram of the upper insert of the capsule.
Fig. 4 is a representation of a three-view diagram of the lower insert of the capsule. Fig. 5 is a representation of a three-view diagram of the capsule cover.
Implementation of the invention
The capsule comprises a body (1), an upper insert (2) a lower insert (3) and a cover (4).
When placing a coin into the capsule the following actions must be performed:
- the coin must be fastened using holders (the upper and the lower insert) so its position is fixed in place inside the capsule, namely, the coin must be jammed between holders fixed inside the body
- after the coin is fixed, the body and the cover are joined using ultrasonic welding.
Industrial applicability
The use of the capsule for coin storage and examination will ensure preservation, convenient storage and identification of collector coins. At the same time, it will provide a possibility to use the capsule with coins of various shapes and sizes, including irregular shapes.
