A self-closing tilting valve sealingly insertable in a lid for a container fillable with product under excess pressure and provided with a valve mounting, comprises a mandrel having a base part and a tip part, and an enveloping nozzle surrounding the mandrel and having an axial product passage receiving the mandrel therein, a head part with an outlet opening for the axial passageway, a foot part having a bottom opening for the axial passageway, and an intermediate portion extending axially between the head part and the foot part, and being substantially rigid. The mandrel top part bears a conically tapered sidewall of axially outwardly increasing diameter, and the head part of the nozzle has an outer end wall about the outlet opening correspondingly tapered to sealingly contact the top part sidewall in closed position. The intermediate portion of the nozzle between the head part and the foot part must be substantially rigid. The mandrel projects downwardly out of the foot part of the nozzle and has a base part thereof extending radially outwardly beneath the underside of the nozzle foot part. Distancing noses are provided at the lower end of the conically tapered sidewalls, which distancing noses cause a gap to be formed between these sidewalls when the mandrel is drawn downwardly axially into the axial passage during opening of the valve by tilting.

A process is described for producing a valve-and-lid assembly composed of a lid and a valve body each of which has a determined configuration and is produced separately in finished condition, the valve body from a synthetic resin of physical properties similar to those of Hytrel, with a Shore hardness of about 78 to 92 when the valve body is to be assembled with an upper body portion resting on the outer lid face about a collar of the lid; and of about 70 to 92 when the valve body is to be introduced completely into the lid collar. The valve body is then placed partially into the collar, or on the mandrel of a pressure piston, and then abruptly struck by the piston to be rammed fully into the collar and stretched so that a lower head of the valve body is moved downwardly just out of a central lid opening at an internal collar end. The mandrel is then withdrawn, permitting the valve body to contract whereby its head sealingly engages the rim about the central opening of the collar.

A self-closing discharge valve for use in a pressurized container from which a liquid product is to be dispensed, with the aid of a propellant, in liquid, pasty or foamy condition, which valve opens automatically when an external part thereof is moved in a given direction, and comprises

Discharge valve for use in a pressurized container

A valve-and-lid assembly comprises a self-closing discharge valve constituted by a dome part, having a central opening, of a lid closing the open top end of a pressurized container and serving as the obturating member of the valve by obturating ducts through a valve disc of elastically resilient material which is lodged in the dome part. When opening the valve by downward or tilting pressure exerted with the aid of a tubulure or the like actuating member on the valve disc, the latter is deformed so as to establish free communication between at least one of the ducts therein and the hollow interior of the tubulure which can carry a conventional atomizer head having a spray nozzle.

Self-closing valve-and-lid assembly

A valve-and-lid assembly adapted for closing off the open top end of a pressurized container comprises a lid having a dome part protruding on an upper or lower face of the lid and having a central opening. A valve disc of elastically resilient material is lodged in the dome part and extends with a valve head part thereof through the central opening. The latter is surrounded by an axially extending collar portion of the dome part depending from a flat top wall of the latter and having an annular rim about the opening which is in sealing contact with a contact face of the valve head when the valve is closed, thereby obturating product ducts provided in the valve disc. Pressure on the face of the valve disc opposite the valve head by means of a tubulure or the like actuating means, which can carry a conventional atomizer head or filling head, moves the contact face of the valve head away from the collar portion rim and opens free communication between the interior of the container covered by the lid and the interior of the tubulure.

A sealed can or similar container having a can body the wall of which is internally lined with a coating is sealed with a deep-drawn membrane in a manner which leaves on the inside of the can wall surrounding a can top opening an annular zone uncovered by said membrane, but with the coating of the can wall intact, which annular zone extends between a lower internal edge of a rim-covering part of the membrane and the upper edge of a collar part of the membrane, which collar part is integral with, and extends upwardly from and surrounds a flat part of the membrane which covers the said can opening, and which collar part is glued or welded to the inside of the can wall beneath said uncovered zone. A preformed closure element destined for sealing fastening in a can opening, a process and apparatus for producing a rupturing zone in which preformed closure element, and a process and apparatus for manufacturing a sealed can with the aid of the preformed closure element are also described.

A fountain brush has a bristle carrier and a set of bristles on one end thereof, a handle attached to the other end of the bristle carrier and a reservoir a channel extends axially through the bristle carrier from the reservoir into the bristle-bearing end of the carrier; the channel has at least one radial outlet orifice in the sidewall of the carrier. A slide valve member is guided sealingly in the interior of the channel. A closure member is adapted for hermetically closing the reservoir. A connecting rod extends substantially axially through the interior of the reservoir and connects the actuating device and the slide valve member to one another. The closing member is at such distance from the slide valve member that, in a filling position in which medium can be filled into said reservoir, the closing member leaves the open end of the handle free while the slide valve member seals off the reservoir; an elastically deformable bellows is connected hermetically sealingly with the closing member, and with the inner wall of the handle, in actuated as well as in unactuated position of the actuating device, thereby closing the reservoir; the slide valve member obturates the orifice when in the said unactuated position and, upon actuation by pressure on the closing member, is moved into the blind end of the channel past the orifice clearing the latter.

Fountain brush

A fountain brush having a bristle carrier and a set of bristles thereon, a handle attached to the bristle carrier and forming a reservoir for a liquid or pasty medium, and an actuating device, attached to the end of the bristle carrier, remote from the bristles and comprising an actuating press-member, which is attachable to the inner wall of the handle via compressible bellows means is described. A channel is provided leading through the bristle carrier from the reservoir to an outlet orifice between the bristles, and an obturating member which either closes the orifice or clears it for the discharge of the medium therefrom. The obturating member is devised as a slide valve body guided in the interior of the channel and travels sealingly along the channel wall; the compressible bellows means is devised as a return spring member and is sealingly connected to the actuating press-member only after the medium has been filled into the reservoir; finally a connecting member, extending through the interior of the reservoir, is provided which rigidly connects the press-member and the slide valve body to one another and is of such length that, when the bellows means are relaxed, the slide valve body seals the outlet orifice, while it clears the orifice when the bellows means are compressed.
