A spray attachment for bringing out fluid substances in the manner of a jet includes a cap with an annularly peripheral, closed skirt with a wall, on whose inner side or outer side first fastener is integrally formed. The first fastener can engage a corresponding second fastener of an outer wall or inner wall of a container neck. The skirt at a longitudinal end is closed off by a cover surface having a recess. A receiving part for receiving an insert part is arranged in the region of the recess, and includes a conical receiving surface for receiving a conical peripheral surface of the insert part. The conical receiving service and the conical peripheral surface delimit at least one through-channel for fluid substance, through which the fluid substance can be brought out.

An apparatus suitable for pressurized liquid transfusion is disclosed. The apparatus includes a nozzle assembly enclosed by the combination of a casing and a check nut. The nozzle assembly includes an elastomeric ring and a nozzle received by the combination of a cap and a receptacle. The elastomeric ring surrounds the nozzle and a proper seal is created therebetween. The dimension of the internal contour of the elastomeric ring is a bit smaller than the nozzle. The elastomeric ring is stretched so as to receive the nozzle. Additional processing may be applied to the elastomeric ring to achieve a different type of proper seal. Pressurized liquid passes through the apparatus so as to be transfused. The aforementioned seal serves to avoid leakage or pressure loss at the apparatus so as to avoid undesired aerosolization effects of an aerosolizer the apparatus is installed in.

An applicator for a syringe is provided that includes a hub configured to be disposed at least partially within a nozzle of the syringe and defining a fluid passage therethrough, with one or barbs on the hub that frictionally and sealingly engage an interior of the nozzle in a manner minimizing void space associated with waste of deliverable material, and an applicator tip extending distally from the hub. The barb(s) may have varying diameters in order to enable the applicator to be engaged and utilized with syringes having different diameter nozzles. Further the fluid passage through the hub and applicator tip is dimensioned to minimize the volume of material that is retained within the applicator after use, thereby increasing the volume of material that can dispensed from the syringe for use in a procedure or procedures and minimize waste.

A dispensing head for a supply tube that enables material to be evenly applied adjacent to the peripheral edge of a thin structure, such as a vehicle door. The dispensing head has a first end with a first opening and a second end with a discharge opening. A guide extends from the second end. The guide includes a descending element and a lateral foot element, wherein the bottom surface of the second end, the descending element, and the lateral foot element define three sides of an open gap space. The dispensing head is attached to a supply tube. The thin structure is positioned within the guide. The hook shaped guide positions the discharge opening a set distance from the application surface on the thin structure. The guide is moved along the peripheral edge where the material can be dispensed evenly at a set distance from the peripheral edge.

An atomizing nozzle arrangement (1) is described including a housing (2, 3) having an inlet, a valve seat (6), a valve element (7) interacting with the valve seat (6), restoring means (8) acting on the valve element (7), and an orifice (9), wherein the valve element 7 cooperates with a guidance element (12) which is arranged in a bore of the housing (2, 3). In such an atomizing nozzle arrangement noise should be kept low. To this end, a combination of the guidance element (12) and the valve element (7) includes a surface having a smooth transition in a direction away from the valve seat (6).

A washer nozzle comprises a first flow path that extends in the longitudinal direction of an arm piece, a second flow path that is connected to the downstream side of the first flow path and that extends in a direction intersecting the longitudinal direction of the arm piece, an upstream opening that opens the first flow path and the second flow path toward one side in the longitudinal direction of the arm piece, and a blocking member that is provided with a joint part connected by a washer tube and that blocks the upstream opening.

The present invention relates to a molten metal plated steel sheet manufacturing method for cooling a molten galvanized layer with high efficiency when manufacturing a molten galvanized steel sheet, and the purpose of the present invention is to provide a method for manufacturing a molten galvanized plating, wherein a molten galvanized steel sheet having an aesthetically pleasing surface without fitting defects, drop mark defects, and linear comb-pattern defects can be stably obtained by cooling a galvanized layer with high efficiency during a molten metal plated steel sheet manufacturing process. This method for manufacturing a molten galvanized steel sheet having excellent surface properties is characterized by comprising the steps in which a molten galvanized layer is formed on the surface of a steel sheet while the steel sheet passes through a galvanizing pot, the thickness of the galvanized layer formed on the surface of the steel sheet is adjusted while the steel sheet passes through a gas wiping device, the steel sheet that has had the thickness of the galvanized layer adjusted undergoes a primary cooling while passing through a bottom cooler, and the galvanized steel sheet that has undergone the primary cooling undergoes a secondary cooling while passing through a cooling chamber, wherein: the primary cooling is performed with cooling air blown from the bottom cooler until right before a galvanizing solution of the galvanized layer attached to the surface of the steel sheet becomes solidified, the amount of air blown being adjusted according to the temperature of the galvanized layer attached to the surface of the steel sheet; and the secondary cooling is performed with ionic air generated from an ionic air generator provided in the cooling chamber and a spray solution sprayed from a solution atomization part, the secondary cooling being performed from the start of the solidification of the galvanizing solution until the end of the solidification, and the cooling chamber cooling the galvanized steel sheet while moving up and down according to the temperature of the galvanized layer attached to the surface of the galvanized steel sheet.
