摘要:
A device for packaging and dispensing, under pressure, a product is provided. The device can be particularly advantageous for cosmetic products and includes a container containing the product to be dispensed under pressure, a propellant in the form of a liquefied gas having a gaseous phase and a liquid phase, and at least one retaining member able to trap the liquid phase of the propellant. The retaining member includes at least one portion that is permeable to the gaseous phase of the propellant. A valve is associated with the container and includes a body that includes a first passage able, when the device is in a first position, to cause the product contained in the container to enter the valve body when the valve is actuated, and a second passage able, when the device is in the first position, to cause the propellant contained in gaseous form in the container to enter the valve body when the valve is actuated.

The present invention relates to a spray can and a pressure releasing structure thereof, in which the pressure in the spray can can be easily and quickly released. A spray can 200 comprises a sealed can body 14 for holding a compressed fluid such as cosmetics, paints, or propane gas, a spout path 16 for leading the fluid in the sealed can body 14 to the outside, an opening/closing means 18 for opening and closing the spout path 16, and an open-state maintaining means 202 for maintaining the spout path 16 in its open state.

A discharge apparatus (1 or 41) for media to be atomized in ultrafine form has a discharge nozzle (3) with a sponge-like medium receiver (10), into which issue on the one hand a functionally closed source unit (50) for the medium and on the other a conveying or delivery device (11) for compressed air, so that by a control mechanism (40) initially a drop of medium spreads out in capillary manner in the receiver (10), after which by random actuation an air pressure surge flows through the receiver (10) towards the medium outlet (4). The medium is discharged from the medium receiver (10) in an already finely divided state, whirled up and once again is finely atomized in the vicinity of an impact atomizer (30) until it passes into the open with a minimum droplet size of max. 2 .mu.m.

A package (1) in the form of a spray container in which slides a piston. There is a dispensing nozzle at one end of the container and a liquid to be dispensed between the piston and the nozzle. A compressed gas occupies the container on the other side of the piston. The seal between the piston and the internal side wall of the container is ensured by shallow annular grooves in the internal side wall, having an interval less than 1,000 .mu.m and a depth no greater than 100 .mu.m.

A fluid dispenser is provided with a carrier having a deformable container capable of being filled with a fluid material to be dispensed, the container being sealed by a closure valve device, with resilient device acting upon the container to place its contents under pressure, and a control device being provided for opening of the closure valve device to permit contents of the container to be ejected by pressure from the resilient device.
摘要:
A spray dispenser comprises a container in which a product-containing bellows is situated above an energy storing bellows. A piston is disposed within the container below the energy storing bellows. A sleeve surrounds the container and is threadedly connected with the piston whereby rotation of the sleeve relative to the container causes the piston to rise and compress the energy storing bellows. The energy storing bellows thus pressurizes the product-containing bellows to expel the product when the valve is opened. The outer diameter of the bellows is of progressively reduced diameter to enable the bellows segments to become more snugly nested within one another when collapsing.

A pressure container suitable for gases, liquids, paste-like materials or similar products comprises two chambers sealed against each other. One of the chambers is constituted by a flexible bag connected to a valve plate common to both chambers. The valve plate is provided with an extension tube extending into the interior of the container. A neck portion of the flexible bag is glued or welded to the extension tube. The outer contour of the extension tube comprises radially extending projections which are bounded by two outer faces each, and which, at their inner ends, merge tangentially into the circle-shaped contour of said first extension tube means and converge into a sharp edge at their outer ends. In this way, a reliable sealing of the two chambers against each other can be achieved.

This invention relates to a multi-fluid mixing and automatic mettering dispenser for co-dispensing a pressurized permanent hair dye composition, having a first container containing a hair dye and propellant material, a second container disposed within the first container and containing a dye developer material, a nozzle structure defining a discharge passageway and a valve structure having first and second valves for controlling passage of the materials through the nozzle. The nozzle structure permits concurrent operation of the first and second valves to permit simultaneous flow of the materials form the first and second containers through the discharge passageway under the influence of the propellant, such that the materials exit from the dispenser at an overall flow rate not greater than about 1.8 gm/sec, and the flow ratio of the hair dye and propellant material exiting the first valve to the dye developer material exiting the second valve is in the range of about 1.9 to 2.5:1.
摘要:
A flexible bag (4) that is filled with a product (5) is accommodated in a rigid container (1). The bag is welded to a valve unit A, which provides an absolute seal for the container (1) by means an annular membrane (17) that is pressed into the neck of the container (19) and a double annular rib (19) that is pressed into an annular groove (20) as well as by the welding (23) of a closing sleeve (22) to the container (1). The product (5) is forced into the bag (4) and compressed air is forced through a drilled hole (11) of a valve plate (7) into the container (1) by downward pressure on a valve plunger (8). The valve unit (A) closes the bag (4) a sealing washer (12), working as a non-return valve, seals the container (1) and avoids any loss of pressure, whereafter, when the valve unit is open, the container pressure compresses the bag ( 4) so that the product is dispensed through a spray head (14).
