Description
The present invention relates to a safety valve for a gas container, and more particularly to a safety valve for a portable gas container which is easy and safe to manufacture, a gas container employing the same, and a manufacturing method for manufacturing such a gas container.
In general, a gas container is a container which can be completely enclosed for storing and transporting gas or liquid. There are various types of gas containers, from containers for storing industrial gases to gas containers for domestic use.
Examples of such gas containers which are routinely used by ordinary people include spray-type cosmetics, fragrance, mosquito repellent, and gas containers for portable burners. The everyday use of gas containers is easy to carry and the replacement cycle is short because only a modest amount is contained.
One of the important points in these gas containers is safety and ease of fabrication. Since gas containers used routinely are generally used in close proximity to a user, they need to be secured, and they are frequently used and replaced. Therefore, it is necessary to restrain the factors that raise the cost as much as possible.
In general, gas containers such as spray-type cosmetics, fragrance, and mosquito repellant fill more gas than the contents in order to use the entire contents. Therefore, even if all the necessary contents are discharged, the gas remains in the gas container at all times, which may explode when heat or pressure is applied. Accordingly, it is also important to discharge residual gas.
One of the safety valves of the conventional portable gas container is a structure in which the valve stem is not exposed to the outside, so that the gas inside the container can not be injected to the outside when not mounted on the portable burner. This is advantageous in preventing internal gas from leaking out during transportation, storage or transportation, but it is difficult to lower the pressure by discharging gas when the pressure inside the container increases.
The present invention provides a safety valve, a safety container, and a safety container manufacturing method for a portable gas container which is simple in construction and is easy to manufacture, has excellent safety, and can be manufactured quickly at an economical cost.

Here, the opening and closing member may be formed with a protrusion which can be pulled out from the outside to discharge a remaining amount of gas.
The opening and closing member may be formed with a seating groove for seating the packing member.
Further, the support portion is a protrusion formed around the depression, and the cover member is supported by the protrusion so that the position is not moved.
In order to solve the above-mentioned problems, the present invention provides, as an embodiment of the present invention, a body having an internal space in which a gas can be stored, a bottom surface of the body being closed and a depression recessed into an internal space of the body, And a safety valve such as the above-described safety valve coupled to the bottom plate to open and close the hole of the depressed portion.
In order to solve the above problems, the present invention provides a method of manufacturing a gas container, comprising: a first step of forming a bottom plate of a gas container by a pressing process so as to form a recess at a central portion of the depressed portion, Closing member, an elastic member, and a cover member in such a manner that the packing member, the opening and closing member, the elastic member, and the cover member are sequentially disposed on the depression formed in the bottom plate of the gas container; A third step of fixing the elastic member in a compressed state by placing a base plate of the gas container inserted and inserted into a jig, a step of clamping the cover member by a clamping press to a base plate of the gas container fixed by the third step A fourth step of forming a protrusion around the depressed portion so as to be supported by the bottom of the gas container, and a fourth step of bonding the body of the gas container to the bottom plate of the gas container manufactured by the fourth step It proposes a production gas vessel comprises the step 5.

In order to prevent the explosion of the gas container, the gas container is usually pierced to discharge the remaining amount of gas. In recent years, there have been many cases where such operations are carried out using apparatuses for piercing gas containers. These devices punch holes in the outer wall of the gas container. However, if the user is surprised by a sudden burst of gas during punching, or if the punching device is made of metal such as iron, there is a risk of fire because flames may be generated and transferred to the discharged gas. By using the above-described configuration of the protruding portion, it is possible to discharge the remaining amount of gas safely and conveniently.
