Abstract
Abstract A two-piece nozzle for use on hand actuated pump dispensers is disclosed. The nozzle features a tubular member, which may be a part of the main body of the pump, having a circular, planar face at its terminal end. A hollow bore extending through the tubular member and the hollow face is in liquid passage communication with a recess in the planar face. A cap is rotatably mounted to the tubular member and has an end wall with a planar inside surface which will form an interface with the circular planar face of the tubular member. Radially displaced from the center axis of the circular skirt is a dispensing orifice which is registerable with the recess present in the planar face of the tubular member. A sealing boss surrounds the dispensing orifice and bore to provide a liquid-tight seal with the planar face when the orifice is not in registration with the recess. Mounting structure is provided on the cap and tubular member for achieving a rotating mount of the cap to the tubular member.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
190 words
A nozzle for the dispensing of liquids, said nozzle comprising: a. a tubular member having at its terminal end a circular, planar face, said planar face being coaxial with a hollow bore extending through said tubular member and said planar face, and said planar face having at least one recess in liquid passage communication with said bore; b. a cap having i. an end wall with a planar inside surface, ii. a cylindrical, hollow skirt projecting from said inside surface, a dispensing orifice in said end wall eccentric with the center axis of said circular skirt and registerable with said recess in said planar face; iii. a sealing boss on said inside surface surrounding said dispensing orifice and surrounding said bore when said cap is fitted to said tubular member, said sealing boss forming, throughout its extent, a liquid-tight seal with said planar face, except for that portion of said boss overlying said recess when said orifice is in registration with said recess; and c. first and second mounting means, carried by said tubular member and said cap respectively, for achieving rotatable mounting of said cap to said tubular member.
Claim 2
Dependent Claim
190 words
A nozzle for the dispensing of liquids, said nozzle comprising: a. a tubular member having at its terminal end a circular, planar face, said planar face being coaxial with a hollow bore extending through said tubular member and said planar face, and said planar face having at least one recess in liquid passage communication with said bore; b. a cap having i. an end wall with a planar inside surface, ii. a cylindrical, hollow skirt projecting from said inside surface, a dispensing orifice in said end wall eccentric with the center axis of said circular skirt and registerable with said recess in said planar face; iii. a sealing boss on said inside surface surrounding said dispensing orifice and surrounding said bore when said cap is fitted to said tubular member, said sealing boss forming, throughout its extent, a liquid-tight seal with said planar face, except for that portion of said boss overlying said recess when said orifice is in registration with said recess; and c. first and second mounting means, carried by said tubular member and said cap respectively, for achieving rotatable mounting of said cap to said tubular member.
Claim 3
Dependent Claim
61 words
The nozzle of claim 1 wherein said first mounting means is an annular flange integral and coaxial with said tubular member and said second mounting means is a cylindrical, hollow skirt projecting from said inside surface and having an inwardly extending protuberance integral with and about the inside diameter of said skirt, said protuberance forming a snap fit with said flange.
Claim 4
Dependent Claim
74 words
The nozzle of claim 1 wherein said planar face additionally has a second recess angularly displaced from said first mentioned recess, said second recess being in liquid passage communication with said bore and said second recess having a radial extent greater than the radial extent of said first recess and wherein, when said orifice is in registration with one of said recesses, said sealing boss forms a liquid-tight seal that surrounds the other recess.
Claim 5
Dependent Claim
12 words
The nozzle of claim 3 wherein said recesses are displaced 180° apart.
Claim 6
Dependent Claim
59 words
The nozzle of claim 3 wherein said cap has a second boss associated with said orifice and surrounded by said sealing boss, said second boss having a configuration to produce a first dispensing mode when said orifice is in registration with said first recess and a second dispensing mode when said orifice is in registration with said second recess.
Claim 7
Dependent Claim
19 words
The nozzle of claim 5 wherein said first mode is a spray and said second mode is a stream.
Claim 8
Dependent Claim
12 words
The nozzle of claim 5 wherein said recesses are displaced 180° apart.
Claim 9
Dependent Claim
22 words
The nozzle of claim 7 wherein said configuration provides a swirl chamber upon registration of said sealing boss with said first recess.
Claim 10
Dependent Claim
13 words
The nozzle of claim 1 wherein said nozzle is of a thermoplastic material.
Claim 11
Dependent Claim
34 words
The nozzle of claim 1 wherein said cap has a second boss surrounded by said sealing boss, said second boss having a configuration to produce a spray upon dispensing said liquids through said orifice.
Claim 12
Dependent Claim
22 words
The nozzle of claim 10 wherein said configuration provides a swirl chamber upon registration of said sealing boss with said first recess.
