Abstract

The utility model discloses a glossy jar with a relief device, comprising a body whose bottom is provided with a relief device, wherein the relief device is composed of a notch line (2) on the bottom cover (1) of the glossy jar. The waveform notch line on the bottom cover of the glossy jar can form circles and the like, therefore, when the pressure of the jar is over the deformation pressure of the bottom cover, the bottom cover will expand, the circle of the notch line will uniformly form puckering points until being broken with the increase of the expansion to realize self relief, thereby realizing safe pressure relief.

Description

The aerosol jar of band pressure relief device

Technical field

The utility model relates to a kind of container of adorning pressed gas, in particular a kind of aerosol jar with pressure relief device.

Background technique

At present, the bottom of aerosol jar all is not provided with pressure relief device, and its bottom generally is circular arc, in case when jar internal pressure was excessive, therefore tank body existed potential safety hazards such as blast owing to there is not the function of release.

The model utility content

In view of this, main purpose of the present utility model is to provide a kind of simple in structure, reasonable in design, aerosol jar that can carry out the band pressure relief device of release when the pressure in the jar is excessive voluntarily.

In order to achieve the above object, the utility model adopts following technological scheme to realize:

A kind of aerosol jar with pressure relief device has tank body, and wherein said tank base is provided with pressure relief device, and described pressure relief device is made of the line of weakness that is arranged on the aerosol jar bottom.

As preferably, described line of weakness is wave band shape, and this wave band shape line of weakness constitutes geometric figure on bottom.

As preferably, at least two of described line of weakness.

The utility model is owing to be provided with the line of weakness that is the wave band type on the bottom of aerosol jar, and this line of weakness can constitute as geometrical shapies such as circles, like this, when the pressure in the jar surpassed the rock deformation pressure that bottom bears, this bottom will outwards be heaved, in case heave, at the uniform formation fold point of line of weakness circled meeting nature, along with heaving increase, the fold aggravation is finally broken.Thereby realized release voluntarily, can play the effect of safe unloading pressure.

Description of drawings

Fig. 1 is the longitudinal cross-section schematic representation of bottom in the utility model;

Fig. 2 is a structural representation of the present utility model.

Embodiment

In order to make those skilled in the art can further understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing.

As shown in Figure 1, the aerosol jar of band pressure relief device has tank body in the utility model, and described tank base is provided with pressure relief device, and described pressure relief device is made of the line of weakness that is wave band shape 2 that is arranged on the aerosol jar bottom 1.This line of weakness constitutes ring shape on bottom, and is provided with three, just three circles.

Like this, when the pressure in the jar surpassed the rock deformation pressure that bottom bears, this bottom will outwards be heaved, in case heave, at three fold points of the line of weakness circled meeting uniform formation of nature, along with heaving increase, the fold aggravation, finally break, thereby realized release voluntarily, play the effect of safe unloading pressure.

But the above only is a preferable possible embodiments of the present utility model, is not in order to limit to claim of the present utility model, so the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, all in like manner to be included in the scope of the present utility model.

Claims (3)

1, a kind of aerosol jar with pressure relief device has tank body, it is characterized in that described tank base is provided with pressure relief device, and described pressure relief device is made of the line of weakness (2) that is arranged on the aerosol jar bottom (1).

2, the aerosol jar of band pressure relief device as claimed in claim 1 is characterized in that, described line of weakness (2) is wave band shape, and this wave band shape line of weakness (2) constitutes geometric figure on bottom.

3, the aerosol jar of band pressure relief device as claimed in claim 2 is characterized in that, described line of weakness (2) is at least two.
