The hairclip () has two legs () and a hinge () with a spring () connecting the legs. The legs () each have a tine base () and a number of curved tines () arranged in rows on one side of it. Each tine base () is adjoined by an actuating section () on the opposite side. The two actuating-sections () are disposed asymmetrically relative to a length of the tine bases () and opposite each other. For the sake of tight spacing and easy manipulation, these hairclips () are placed on the curlers () in such a way that the actuating leg sections () of one hairclip () are not disposed in the immediate vicinity of the actuating leg sections () of an adjacent hairclip ().

Hair clip and method for using said hair clip

A compressed gas container apparatus having at least two compressed gas containers disposed side by side, each for one foamable liquid product which contains a liquidified propellant gas, wherein both compressed gas containers are each provided with a valve; both valves are actuatable in common by a top fitting, and each valve is provided through the top fitting with a connecting conduit; the connecting conduits discharge into a mixing chamber and an expansion conduit adjoins the mixing chamber and on its end has a foam dispensing opening; wherein the connecting conduits and the mixing chamber have such small cross-sectional areas that when a product is dispensed, the products flowing through the connecting conduits and the mixing chamber remain in a liquid phase.

Device for mixing, foaming and dispensing liquids from separate compressed-gas containers

The valve device includes a valve body (3) having an interior chamber (12) and slidably mounted in an outer housing (18) provided with a first gas passage (19) for compressed gas and a second gas passage (20) connectable with the first gas passage (19) when the valve body is in its lower position; a hollow valve stem (4) slidably mounted in the valve body (3) and provided with a lateral opening (11) connecting the hollow valve stem (4) with the interior chamber (12) when the valve stem (4) is in its upper position relative to the valve body; a first seal (10) sealing the interior chamber (12) and the valve body (3) and a second seal (22) provided on an outer periphery of the valve body (3) acting to seal the interior chamber (12) from compressed gas when the valve body (3) is in its upper position. The second gas passage (20) is connected with the first gas passage (19) and with interior chamber (12) in the lower position of the valve body (3). The opening (11) is positioned in the valve stem (4) so that, when the stem (4) is depressed, compressed gas is supplied through the first gas passage (19) and the then connected second gas passage (20) into the interior chamber (12), so that the stem (4) is cleaned by compressed gas flowing through the lateral opening (11) from the interior chamber (12) only when the hollow stem (4) is returned to its upper position.

The permanent wave clip (1) has three curlers (2,3,4) which can be arranged parallel to each other including a releasable and exchangeable hair tip curler (6) rotatable about its axis which is clipped in a curler holder (7). A curler (2), which is a hair root curler (9), has a smaller diameter than the hair tip curler (6). The central hair curler (3) can be pivoted out of and into a parallel relationship with the other curlers by means of a pivot (17) in a preferred embodiment. The permanent wave clip (1) is easily operated and provides an outstanding hair root curl.

A two-chamber container for accommodating flowable substances separately from one another has an upper chamber and a lower chamber, a reduced diameter bottle which separates the chambers from one another and is provided with a plug in a plane of the reduced diameter, a rotary cap provided with a plunger and turnable so that the plunger is pressed from the plane of the reduced diameter into the lower chamber so as to bring both substances together. The rotary cap has a thread in the upper chamber, while the plunger has a threaded portion engaged in the thread of the rotary cap. The plunger is formed as a tubular plunger which has a first end and a second end formed so that in a base position the first end of the plunger is connected with the threaded portion of the plunger in fluid-tight manner and the second end of the plunger extends through the plug into the lower chamber, and the plunger is connected with the plug in fluid-tight manner.

In a container for a first substance, an ampoule, which can be broken while the container is closed, is provided for a second substance. The container has a base and a rotatable cap. The ampoule spike is mounted in the region of the base. An eccentric on the cap is operatively connected to the ampoule that the base of the ampoule moves transversely to the longitudinal axis of the container on turning the cap, and the ampoule is mounted so as to be pivotable about the region of a predetermined breaking point.

Apparatus for keeping and mixing two substances

An arrangement for spraying liquid from a bottle comprises an air pump and a member which actuates the pump when a spraying action is desirable. The air flow is transmitted into the interior of the bottle to pressurize the liquid and urge the latter into a liquid outlet conduit which has a lower end extending into the liquid in the bottle and a discharge end outside the bottle. The arrangement is further provided with an element for spraying the liquid when the latter under the pressure supplied into the bottle enters the discharge end of the outlet conduit.
