A valve for dispensing a fluid from a container and a dispensing apparatus with such a valve are proposed. The valve has a spring device for returning a valve element to a closed position, the spring device being integral with the valve element. The spring device has a contact area for contact with a counterface of a valve body, the contact area forming an elevation of an outer surface of the spring device. The spring device and the counterface are in point contact with each other in any position of the valve element. The materials of the contact area and the counterface are matched to each other in such a way that they slide silently on each other. A seal of the valve is made of polyethylene or a thermoplastic elastomer. The valve is preferably designed as a full plastic valve and is easily recyclable.

The present disclosure relates to a valve for dispensing flowable product from a container under pressure, the valve comprising a stem, a seal coupled to the stem, and a mounting cup configured to mount the valve to the container, wherein each of the stem, seal, and mounting cup comprises a recyclable plastic, and wherein the valve is free from a gasket configured to surround an opening of the container to form a seal between the valve and the container. Also provided herein is a container for dispensing a flowable product under pressure comprising the valve as described above.

An aerosol hair care product includes a pressurisable container a propellant, a hair care formulation, and a spraying device. The pressurisable container is at a pressure of 9×10.sup.5 to 11×10.sup.5 Pa. The pressurisable container includes a container wall which encloses a reservoir. The propellant is contained within the reservoir. The propellant includes an insoluble compressed gas and has a first weight. The hair care formulation is contained within the reservoir. The hair care formulation has a second weight and includes starch having a third weight. The third weight is 3 to 15% of a sum of the first weight and the second weight. The spraying device is attached to the pressurisable container. The spraying device is configured to facilitate dispensing of the hair care formulation from the reservoir. The spraying device includes an actuator and a valve.

A stem (1) for a two-way valve has a main body (10) outer face that is substantially cylindrical about a main axis, with (i) a first tubular wall (11) closed at its lower end by a first bottom wall (13) and open at its upper end (111), defining a central
channel (113); (ii) a second tubular wall (12), concentric with the first tubular wall (11) and partially surrounding it, closed at its lower end (122) by a second bottom wall (14) and open at its upper end (121), defining an annular channel (123) around the central channel (113), one or more through-holes (124) bringing the inside of the annular channel (123) in contact with the cylindrical outer face of the main
body (10); and (iii) a tubular insert (20) dimensioned so as to be able to be inserted into the annular channel (123).

A polymeric aerosol dispenser that is recyclable. The recyclable polymeric aerosol dispenser including all polymeric components. These components being selectively either fixedly joined or separably joined based on the material composition of the component. Further, components may be selected for their density and, thus, their ability to float or sink during the recycling process. The recyclable polymeric aerosol dispenser is designed to minimize its impact on the PET recycling stream and to align with industry recyclability guidelines.

An aerosol hair care product that includes a dispenser container containing a compressed gas, an adsorbent material, a propellant and a reservoir filled with a hair care composition such as a hairspray or dry shampoo. The hair care composition is dispensed from the container without substantial clogging in the valve assembly or outlet nozzle and exhibits no substantial change to the mass flow rate and/or average particle size distribution over the life of the product.
