The present invention relates to a gas container.
Referring to
The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art.
The primary objective of the present invention is to provide a gas-tight container.
According to the present invention, a gas container includes a bag, a mouth and a connector. The bag defines a space for storing gas and an aperture for passing the gas. The mouth includes a first end for connection with a valve and a second end inserted in the aperture. The connector is located between the bag and the second end of the mouth.
The present invention will be described through detailed illustration of embodiments referring to the drawings.
Referring to FIGS. 2˜4, according to a first embodiment of the present invention, a gas container 10 includes a bag 20, a mouth 30 and a connector 40.
Referring to
The mouth 30 is made of polyoxymethylene. The mouth 30 includes a first end and a second end. A valve (not shown) is installed in the first end of the mouth 30. The second end of the mouth 30 is inserted in the aperture 22 of the bag 20. A plurality of ribs 32 is formed on the second end of the mouth 30. An aperture 33 is axially defined in the mouth 30.
The connector 40 is located between the inmost layer 26 of the bag 20 and the second end 32 of the mouth 30. The connector 40 is made of polyamide. Polyamide and polypropylene can be bounded together tightly when they are subject to heat. Polyamide and polyoxymethylene can be bounded together tightly when they are subject to heat. Hence, the connector 40 forms a good connection between the inmost layer 26 of the bag 20 and the second end of the mouth 30 after they are heat pressed. Futhermore, the ribs 32 enhance the gas-tight connection of the mouth 30 with the connector 40.
The present invention has been described through detailed illustration of two embodiments. Those skilled in the art can derive variations from the embodiments without departing from the scope of the present invention. Therefore, the embodiments shall not limit the scope of the present invention defined in the claims.
