Abstract:
A dispensing closure for dispensing a flowable product from a squeeze-type product container includes a closure body having an upper deck, an exit orifice, and a skirt configured to attach to the product container. A measuring reservoir is received in engagement with a lower surface of the upper deck. The measuring reservoir is filled with a measured dose of flowable product through flow ports when the container is inverted. A piston valve is slidably movable within the measuring reservoir between an open position and a closed position. The piston valve is movable from the open position to the closed position to dispense the measured dose of product responsive to pressure within the container induced by squeezing.
Abstract:
A nozzle arrangement that produces an atomised spray or foam wherein the nozzle arrangement comprises a nozzle body with an inlet for a pressurized fluid into a chamber with an outlet orifice in the downstream wall and a prodder with a tapered conical tip wherein the prodder is inside of said chamber and at least part of the tip of the prodder protrudes inside the outlet orifice creating at least one circumferential gap between the prodder tip and the outlet orifice whereby the fluid spins around at least part of the prodder tip and out through the circumferential gap and produces an atomized spray or foam with a substantially full cone shape.
Abstract:
A module for dispensing a product intended to be mounted on a conduit (4) for pressurised supply of the product. The module has a path (2) for retrieving the product from a supply passage (5) which is intended to be in communication with the conduit to a passage (3) for discharging the product for the dispensing thereof. The retrieval path having at least one downstream conduit that opens into the discharge passage (3) and at least one upstream conduit that is in communication with the supply passage (5). The upstream and downstream conduits having a U-shaped junction that is designed to place the conduits in communication. At least one of the conduits being delimited by at least one wall that is capable of providing a microbiocidal action on the product contained in the conduit.
Abstract:
Dispenser with a liquid storage unit, a dispensing head with a perforated plate component which has at least 25 dispensing openings in a dispensing opening region, with a pre-chamber connected upstream of the dispensing openings of the perforated plate component and from which the dispensing openings are supplied, and a connecting channel which connects the liquid storage unit to the pre-chamber. The perforated plate component is fastened on the dispensing head in an edge region and the dispensing opening region is pressed into a curved form by means of a curvature body which is arranged in the pre-chamber and acts with force upon the perforated plate.
Abstract:
Liquid dispenser for discharging pharmaceutical liquids, having a housing, an outlet opening and an outlet valve assigned to the outlet opening. The outlet valve includes a pressure chamber arranged upstream of a valve opening and delimited to one side by a valve plate of a valve body. By increasing the pressure in the pressure chamber, the valve can be opened. The pressure chamber has a flat form and has a large surface area in contact with liquid in relation to the volume.At least one portion of the valve plate which is in contact with liquid in the pressure chamber is of a valve plate material produced using metallocenes as catalysts.
Abstract:
Fluid discharge head having a discharge nozzle which can be placed on a discharge device and which holds a medium guide and a medium outlet at the end of a medium guide, in the region of the medium outlet a movable closure element that can be moved into an open position is provided and, for the purpose of actuating discharge, the discharge nozzle and the discharge device can be moved axially towards each other, for which purpose the discharge nozzle has a skirt to form a sliding guide with a section on the discharge device, the skirt (9) of the discharge nozzle (5) being assigned a second, additional skirt (12) in order to form an annular bush (13) which can be mounted such that it can be displaced longitudinally on a section (11) of the discharge device (2) that is formed as an annular shaft.
Abstract:
A fluid material dispensing kit including a pouch, provided with a flexible casing and a dispensing case provided with a cover that is to be mounted onto a base. The cover includes an upper recess that has a manually flexibly deformable wall mounted thereon. The wall has a dispensing opening, and the cover is provided with a lower reinforcement that defines, with the wall, a pumping chamber. The reinforcement has a supply opening. The distribution opening and supply opening are provided with, respectively, an output valve and an input valve. The pouch has, built therein, a coupling provided with a well that is sealably covered by the casing of the pouch, and the reinforcement includes a nipple that is to be placed into the well. The nipple is set up so as to enable the perforation of the casing during the placement thereof into the well.
Abstract:
Fluid discharge head having a discharge stub (5) which has a discharge opening (6) and in which an inner sleeve (7) is arranged which has a media channel (8) and which receives a spring-loaded valve body (10) self-acting closing the discharge opening (6) by a compression spring (20), the valve body (10) being formed as a cylindrical piston, which is axially displaceable in a cylinder chamber (12) formed by the inner sleeve (7), an upper valve seat (14) and a lower valve seat (15) being provided for the piston ends (16, 17), and the valve body (10) having an intermediate valve plate (18), which forms a chamber bottom of a pressure chamber (19) which is connected to the media channel (8) and in which, in order to open the upper valve seat (14), a media discharge pressure can be set and an opening characteristic is determined by a transmission ratio of the opening diameter of cylinder chamber (12) and media inlet in the area of the lower valve seat (15), characterized in that the transmission ratio is greater than 2 and the choice of the spring stiffness of the compression spring (20) establishes the media discharge pressure in the pressure chamber (19).
Abstract:
The invention relates to a metering device for metered dispensing of a fluid, in which a storage container is connected to a metering head, a spindle being guided in the metering head and having a through-channel for the fluid to be transported.
Abstract:
A device has a first part with a valve seat and storage chamber, and a second part with a flexible valve cover and actuator. The storage chamber may be formed from a pre-form blow-molded into a flexible pouch defining a variable-volume storage chamber. The flexible valve cover and valve seat form a normally closed valve seam therebetween. The valve cover is movable in response to fluid at an inlet to the seam exceeding a valve opening pressure of the one-way valve between (i) a normally closed position with valve cover and valve seat in contact with each other and defining the normally closed seam, and (ii) a second position with at least a portion of the valve cover spaced away from the valve seat to allow the fluid to pass through the seam. The one-way valve may have anti-spritz features for using the device to dispense a substance, such as to the eye. The device may contain prostaglandins without the device material absorbing the prostaglandins material and/or without the material being adsorbed into the drug.
