Sprayer-doser device for distributing e.g. perfume, has seal placed between pump body and push button and cutting element so that action of button enables seal to be in contact with element for piercing seal and releasing/diffusing product

摘要

#CMT# #/CMT# The device has a recipient and/or pump body (1) containing a liquid or viscous product (2), and a pulverizing system comprising a piston (4) and a push button (3) for ejecting the product. A pierceable membrane seal (14) is arranged between the body and the push button and a cutting element (13) such that the action of the push button enables the seal to be in contact with the cutting element through the movement of the seal and the cutting element for piercing the seal and releasing and diffusing the product. #CMT#USE : #/CMT# Used for distributing a liquid or viscous product e.g. perfume, cosmetic product or pharmaceutical product. #CMT#ADVANTAGE : #/CMT# The device is disposable, and distributes the product in small doses. The membrane seal preserves the product against any chemical deterioration due to oxidation with air or oxygen. The arrangement of the pump body ensures a better prehension and utilization comfort. The device is simple and inexpensive to fabricate, efficient and safe. The device is adapted to small containers less than 5 milliliters, requires reduced number of components, simplifies the assembling operation, and prevents involuntary diffusion of the products before utilization. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a sprayer-doser device. 1 : Recipient and/or pump body 2 : Liquid or viscous product 3 : Push button 4 : Piston 13 : Cutting element 14 : Membrane seal #CMT#METALLURGY : #/CMT# The seal is also made of aluminum. #CMT#POLYMERS : #/CMT# The membrane seal is made of synthetic or natural elastomer material such as rubber.
