Description

[Detailed description of the invention] This invention is applicable to aerosol products, that is, various products in which a liquefied gas such as carbon dioxide is sealed together with the required chemical solution, paint, etc. in a container, and atomization is performed via the pressure gas generated by the liquefied gas. The present invention relates to a device that allows the user to easily detect the amount of content inside the device from the outside. Except for some of the aerosol products mentioned above, which are made of transparent materials such as resin and glass, most of them are usually in metal containers, which makes it inconvenient to calculate the consumption amount because it is not possible to see the remaining amount of the contents. However, especially with fire extinguishers, there were disadvantages such as having to stock up on extra supplies due to concerns about insufficient capacity.

This device utilizes the principle of a spring scale to make it possible to always know the content inside the container.Explaining the embodiment of this device with reference to the drawings, the overall structure is such that the bottom edge is connected to the required aerosol. A clamping portion is formed on the upper outer circumferential surface of the mounting tube 3, which is formed on the elastic clamping edge 1 to be suspended and fixed to the tightened portion corresponding to the shoulder of product a, and the bottom plate 2 is stretched upwardly inside. 4, and a spring 6 with an outer diameter that matches the inner surface of the mounting tube 3 is installed inside, with both ends connected to the lower surface of the top plate 7 of the grip tube 5 and the bottom surface of the mounting tube 3. It is interposed so as to be locked and fixed to the upper surface of the bottom plate 2 and constantly pull the top plate 7 and the bottom plate 2. This spring 6 is set to a predetermined strength so that it is stretched downward in response to the weight of an aerosol product having a sufficient internal capacity.

This invention has the above-mentioned structure, and the required aerosol product a, for example, a fire extinguisher placed in a suitable place, is attached to the upper end of the fire extinguisher as shown in the figure, and is pulled by a spring 6 to hold the grip tube 5. The lower end edge of the mounting tube 3 is mounted on a stepped portion of the circumferential surface of the mounting tube 3.

In this state, as shown in Figure 2, if you pinch the grip part 4 of the grip tube 5 with your fingertips and pull the grip tube 5 upward, if the content of the aerosol product a is sufficient, the spring 6 will be pulled by its weight. The grip tube 5 moves upward with respect to the attachment tube 3 connected to the stretched aerosol product a, and the upper outer circumferential surface 5' of the attachment tube 3 is moved upward.
becomes exposed to the outside world. However, if the content of the aerosol product a has already decreased, when the grip tube 5 is lifted due to the decrease in weight, the mounting tube 3 connected to the aerosol product a will also rise, and the upper outer circumferential surface 5' of the attachment tube 3 will be exposed. Not present or slightly exposed.

As described above, with this invention, by pinching the grip tube 5 and slightly lifting it, it is possible to easily know the content of the aerosol product a. Note that the knob portion 4 may be attached as a separate handle to the upper surface of the grip tube 5, and the upper outer circumferential surface 5' of the mounting tube 3, which is the display surface, may be a colored surface and a scale may be provided as appropriate. good.

As mentioned above, this device simply caps the required aerosol product so that its content can be easily known each time it is used, and protects the nozzle and operation part of the aerosol product a, especially for fire extinguishers. It has many advantages, such as being able to prevent malfunctions. In addition, when the aerosol product is the above-mentioned fire extinguisher or the like, a window hole may be provided on the top and front surfaces of the grip tube 5 and attachment tube 3 so that the product can be operated while being worn.
