JPS607092Y2 - hand-thrown fire extinguisher - Google Patents

Description

[Detailed explanation of the invention] The present invention is based on a fire extinguisher, which is a bag made by polymerizing two synthetic resin sheets of the same shape and size and heat-sealing the edges, and filling the bag with a fire extinguishing liquid. This relates to a hand-thrown fire extinguisher that, when thrown at a burning object in the event of a fire, ruptures and scatters extinguishing liquid, thereby extinguishing the fire.

The loss of human life and damage to buildings caused by flames is enormous every year.

Fires that cause great damage can be extinguished relatively easily in the early stages of outbreak.

For this reason, various fire extinguishers have been on the market in the past, and it is common practice to purchase and keep these fire extinguishers on hand.

However, these fire extinguishers are difficult to operate, making it time-consuming to extinguish a fire, and the hassle of having to refill extinguishing fluid every year, as well as the fact that the extinguisher itself is expensive, has prevented it from becoming widely used in households. has not yet been reached.

For this reason, a hand-thrown fire extinguisher has been devised that can extinguish a fire simply by throwing it, without requiring any difficult operations, and can be produced at a low cost.

However, as shown in FIGS. 1 and 2, in this conventional hand-thrown fire extinguisher, since the two synthetic resin sheets (A and B) forming the bag are square, the fire extinguishing liquid (not shown) is in a rectangular shape.

) If, for example, a shock is applied to the product during transportation or storage, the heat-sealed portion of the heat-sealed portion C that was subjected to the shock may be damaged, even though the impact is slight. It was easy to break, and when thrown at a burning object, only the heat-sealed part on one of the four sides could be broken, so the fire extinguishing liquid only splattered in one direction, resulting in extremely poor fire extinguishing efficiency.

The present invention improves these points, and the heat-sealed part does not easily break even if some impact is applied during transportation, storage, etc., and the heat-sealed part does not break easily when thrown against a burning object. This allows fire extinguishing liquid to be dispersed widely around the area.

Hereinafter, the present invention will be described in more detail with reference to illustrated embodiments.

Fig. 3 is a partially cutaway perspective view of an embodiment of the present invention, Fig. 4 is a plan view of the bag with the fire extinguishing fluid removed, and Fig. 5 is a diagram showing ■-■ in Fig. 4. The line cross-sectional view, FIG. 6, is a comparative illustration of the effects of the present invention and a conventional product.

In this embodiment, a bag body 4 is formed by polymerizing two synthetic resin sheets 1 and 2 having the same shape and size, and then heat-sealing the peripheral edges of the synthetic resin sheets 1 and 2. There is a patent which is characterized in that a fire extinguishing liquid 7 is filled from an inlet 5 with a seal plug 6 provided in one of the two.

In this embodiment, the two synthetic resin sheets 1.2 are shown as being circular, but they may also be perfectly circular.

Next, the operation of the present invention having the above configuration will be explained.

In the present invention, since the two synthetic resin sheets 1 and 2 have a perfect circular shape or a freewheeling shape, when the bag body 4 is filled with the fire extinguishing liquid 7, it becomes a freewheeling ball as shown in FIG.

Therefore, even if a shock is applied to the product during transportation, storage, etc., the heat-sealed portion of the peripheral edge will not easily break because the impact is evenly distributed around the surrounding area.

Furthermore, when thrown at a burning object, the heat-sealed portion will be largely torn because pressure is applied evenly toward the surrounding area as shown by the arrows in Figure 4.

That is, in Fig. 6, A shows the state in which the conventional product breaks, but only one side C' of the heat-sealed part C breaks, and therefore the fire extinguishing efficiency is extremely poor. As shown in FIG. 6B, approximately 80% of the heat-sealed portion 3 is torn, allowing the fire extinguishing liquid 7 to be scattered in all directions.

Therefore, fire extinguishing efficiency can be greatly improved.

In addition, the results of a drop experiment showed that neither the conventional product nor the invented product broke at a height of 1 rrL, but at a height of 1 m30 cm, the heat-fused part on one side of the conventional product broke, whereas the invented product did not. There wasn't.

Furthermore, when the product of the present invention was dropped from a height of 2 m, approximately 80% of the heat-sealed portion was broken.

In addition, the results of a throwing experiment showed that when thrown from a distance of 4rrL with normal force, only the heat-fused part on one side of the conventional product broke, whereas the product of the present invention broke only on the heat-fused part. % broke.

Since the present invention has the above-mentioned structure and function, there is no risk of it breaking even if a certain degree of impact is applied during transportation or storage, so there is no waste due to damage as with conventional products, and it also prevents burning objects from being damaged. When thrown, the heat-sealed part breaks apart, allowing the filled extinguishing liquid to be scattered in all directions, thereby greatly improving fire extinguishing efficiency.

This effect is particularly important in the case of a hand-thrown fire extinguisher, which contains a relatively small amount of extinguishing liquid, and is practically effective.
