Background technique
With the development of society, the material life of people has obtained greatly enriching, people not only chase after product quality
It asks, also to the packaging of the appearance packaging of product especially daily necessities, higher requirements are also raised.Its appearance packaging is not single
It is singly simple container, it is necessary to the convenience taking into account beautiful moulding and using.Squash type or the Packaging Bottle of push type discharging
It is the convenience that is used due to it, handsome in appearance and show one's talent in the packaging of daily necessities.
Patent CN105923281A discloses a kind of self-priming pumping pressure type packaging bottle, and it discloses the dischargings of general push type to pack
The discharging principle of bottle, lotion close discharge nozzle upper end outlet from after discharge nozzle extrusion, through pressing piece, and lotion is hung in discharge nozzle
Wall blocks discharge nozzle and forms vacuum, the smooth extrusion of lotion when reusing to facilitate, as lotion can not cannot achieve if wall built-up
Sealing, will appear disconnected cream, can not normally discharge when reusing.The pump head of the Packaging Bottle of the push type discharging of the prior art is all only
It is a simple discharge nozzle, low in cost although structure is simple, when release key closes Packaging Bottle, lotion is in gravity
Under the action of can flow down, with the extension of use time, the sealing of discharge nozzle lower part is gradually failed, and lotion cannot be protected completely
It holds in discharge nozzle, needs repeatedly pressing just to can guarantee extrusion lotion when in use, seriously affected the using effect of Packaging Bottle.
Therefore, a kind of great reality of piston spring formula toothpaste pump that lotion can be stopped to flow back and enhance sealing effect is developed
Meaning.
Summary of the invention
Present invention aim to address problems of the existing technology, provide a kind of piston spring formula toothpaste pump.
