摘要:
A dispensing device for dispensing a product includes a first chamber configured to initially contain at least one of a first composition and a mixture of the first composition and a second composition, a second chamber configured to contain the second composition, a flow passage for providing flow of the second composition from the second chamber to the first chamber, a selective air intake mechanism configured to selectively be placed in an open position to allow air to flow into the first chamber and a closed position to prevent air from flowing into the first chamber via the selective air intake mechanism, and an actuator configured to be actuated to cause an amount of a product to be dispensed from the first chamber. The product dispensed includes at least one of the first composition, the second composition, and the mixture of the first composition and the second composition. The device is configured such that in response to the product being dispensed from the first chamber, an amount of the second composition flows from the second chamber to the first chamber via the flow passage when the selective air flow mechanism is in the closed position.

A valve component capable of being positioned on a body of a valve includes a valving member configured to cooperate with a seal on the valve to selectively permit fluid flow through the valve when the valving member is in a first position and limit flow through the valve when the valving member is in a second position, a retainer configured to retain the seal on the valve body, and at least one frangible portion connecting the valving member to the retainer. The at least one frangible portion is configured to break when the valve component is positioned on the valve body so as to permit the retainer to retain the seal on the valve body. A valve, a dispenser, and methods of forming a valve using a valve component are also provided.
摘要:
An assembly for packaging and pressurized dispensing of a product, particularly a cosmetic, including a first container which is surmounted by a first valve capable of moving from a closed position to an open position for dispensing the product, and which defines two compartments which are separated in a leaktight manner by a movable piston. The first compartment contains the product and the second compartment receives a propellent gas capable of pressurizing the product via the movable piston. When the valve is in a closed position, the second compartment is substantially at atmospheric pressure.

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.
摘要:
The invention relates to a head for dispensing a liquid product in the form of an aerosol. The dispensing head includes a push-button, at least two ducts housed in the push-button and at least two nozzles provided in the push-button. At least part of each duct is radial, and another part of the duct communicates with the nozzle and is orientated parallel to an axis of the nozzle. The nozzles are arranged so that the sprays leaving each nozzle strike each other in order to provide a single and homogeneous spray. The invention also relates to a dispenser equipped with such a dispensing head.
摘要:
A dispenser includes a valve for dispensing a liquid product to be dispensed in the form of an aerosol with the aid of a propellent gas. The valve is mounted on a container which contains the liquid and is equipped with a hollow operating stem including a product inlet and a product outlet, a push-button for actuating the valve via the stem, first and second nozzles provided in the push-button, and first and second ducts, respectively linking the first and second nozzles to the outlet of the stem. The first nozzle is a nozzle which is capable of delivering a spray having a mechanical effect and the second nozzle is a nozzle which is capable of delivering a spray of product. The dispenser is used especially for spraying hair lacquer.

Roll-on applicator consisting of two components, a ball (9) and a body (1) consisting of a part forming the bottle (2) containing the product (P) to be applied, a part forming the housing (4) for the ball (9) and a part forming the cap (5). This body (1) is obtained by moulding one single component. The invention also relates to the process for the manufacture of the device.
摘要:
The push-button (1) is intended for an aerosol can (B) containing a mousse, in particular a hair styling mousse, this can (B) being provided with a delivery valve (2) capable of being actuated by the push-button (1). This push-button comprises a duct (4) leading towards the exterior for the delivery of the product and adapted to be connected to the valve (2), a deflector (6) being provided across the extension of the delivery duct (4) in order to start the expansion of the mousse before it emerges from the push-button (1). The deflector (6) is in the form of a cap (7), the concave part of which is directed towards the outlet of the duct (4), the end part of the duct being surrounded by a wall (9) defining a chamber (10), the base (11) of which is recessed relative to the opening of the duct (4) and the open end (12) of which is situated above the cap (7).
摘要:
An applicator nozzle may comprise an attachment portion configured to attach the nozzle to a receptacle configured to contain a product and an arrangement of at least two teeth disposed so as to form at least one row comprising first and second end teeth. At least one of the teeth of the arrangement may define a channel configured to be placed in flow communication with product contained in the receptacle. The channel may open on an exterior of the at least one tooth via at least one outlet aperture facing substantially in a direction of at least one adjacent tooth. The nozzle may further define at least one groove and the outlet aperture may open into the groove. The groove may extend from the outlet aperture substantially to a free extremity of the at least one tooth. The arrangement may be formed by a single molded piece and may be configured so as to present an obstacle to product flowing from the at least one outlet aperture beyond the first and second end teeth.
