Description

TECHNICAL FIELD

The utility model relates to devices for transporting and storing various small-sized cargo.

Transportation and storage of various goods in plastic cases is widespread, especially in cases where it is necessary to protect the device from dust, falls, temperature and pressure changes, exposure to chemical environments, etc.

BACKGROUND OF THE ART

Sealed plastic cases of the Korsar brand are widely known (for example: https://korsarcase.ru/catalog/germetichnye-udaroprochnye-plastikovye-keysy/use-is-equipment/), which are used for transporting and storing various goods.

However, known cases are not resistant to combustion and high temperatures (the maximum temperature for use of known cases is +70 degrees Celsius), which can lead to damage to the cargo in the case when exposed to fire or high temperatures.

DISCLOSURE OF THE ESSENCE OF THE UTILITY MODEL

The technical result to be achieved by the claimed utility model is to increase the operational properties of the case and ensure the safety of the cargo by increasing the resistance of the case to combustion and high temperatures.

The declared technical result is achieved due to the fact that the case for transporting and storing small-sized cargo consists of a plastic case and a plastic cover connected to each other by a locking connection, a handle for carrying, and to ensure the tightness of the case it has a pressure equalization valve mounted on the case and a sealing ring, while to prevent damage to the cargo in the case as a result of combustion and exposure to high temperatures, its body is made of Armlen PP TM 15-1AP polypropylene.

The high resistance of Armlen PP TM 15-1AP polypropylene is confirmed in the manufacturer’s catalog (Moscow, 2014), posted on the Internet at: http://polimpartner.by/wp-content/uploads/2018/09/Katalog_na_marochnyi_assortiment.pdf ?ysclid=17ev9t1a6n22337 (see Appendix to the application, page 16).

The applicant has not found sources of information containing the same set of essential features specified in the formula of the utility model, which allows us to conclude that the claimed technical solution complies with the patentability criterion of the utility model “novelty”.

Implementation of a utility model

The case for transporting and storing small-sized cargo (Fig. 1) consists of a plastic body (1) and a plastic cover (2), interconnected by a locking connection (4, 6, 7, 8), a carrying handle (3), to ensure To seal the case, it has a pressure equalization valve (5) mounted on the body and an O-ring (9). To prevent damage to the cargo in the case as a result of combustion and exposure to high temperatures, its body is made of Armlen PP TM 15-1AP polypropylene. The locking connections between the body and the cover can be made in the form of latches (Fig. 1 (4)), mounted on an axis (Fig. 1 (8)) and through a special axis between the body and the cover (Fig. 1 (6)).

According to the manufacturer's data, Armlen PP TM 15-1AP polypropylene has high combustion resistance and has the following characteristics: density 1270 kg/ ^m3 , tensile strength 21 MPa, etc. (see catalogue, pages 3, 16).

The resistance of the case to burning was confirmed by Fire Certification Company LLC (Test Report No. PPB-1109/08-2022 dated 08/12/2022).

The case can be made in different shapes and sizes and colors, and can be additionally equipped with a pair of support wheels (Fig. 6 (11), the fastening of which is ensured by a pair of bolts (Fig. 6 (12)) and a pair of nuts (Fig. 6 (13) ) and a telescopic handle (Fig. 6 (9)), fastening of which is ensured by self-tapping screws (Fig. 6 (10)). Depending on the equipment being transported, the case may be equipped with additional carrying handles and/or a shoulder strap. If additional protection of the case is necessary To prevent unauthorized opening, the case can be additionally equipped with a combination or padlock.

The use of the claimed utility model will prevent damage to the cargo in the case during combustion or exposure to high temperatures.
