US Patent:

46921036, Sep 8, 1987

Filed:

Apr 3, 1986

Appl. No.:

6/847453

Inventors:

Walter F. Anderson - West Covina CA

Assignee:

Calmar, Inc. - Watchung NJ

International Classification:

F04B 2104
F04B 3910

US Classification:

417547

Abstract:

A pump sprayer has a body with aligned relatively large and small diameter cylinder portions and relatively large and small diameter pistons respectively reciprocable therein and delimiting with the cylinder a variable volume pump chamber during pumping, the small diameter piston shifting relative to the large diameter piston for opening the discharge. Cooperating limit stops acting between the piston members limit the relative movement thereof during a valve open position so as to thereby limit the duration during which the discharge passage is open irrespective of different external reciprocating pressures applied during pumping, such that the output of the sprayer is controlled during pumping.

Appl. No.:

5/809008

Inventors:

Ronald A. Meyer - San Dimas CA

Assignee:

Diamond International Corporation - New York NY

International Classification:

B65D 4734

US Classification:

222153

Abstract:

A liquid dispenser has relatively rotatable closure, sleeve and plunger members, the latter two being locked against reciprocation of the plunger member by a misalignment between ribs and grooves therebetween. One of the grooves has a pair of upstanding pegs on opposite sides so as to not only avoid inadvertent alignment when the ribs and grooves are in a misaligned position, but to also permit the plunger and sleeve members to rotate together as the rib abuts against one or the other of the pegs when in a misaligned position. A spacer element surrounding the plunger rod maintains the inlet valve in a closed position despite a slight separation between the plunger and sleeve members when rotated to the misaligned position. Also, the closure member is adapted to be removed only with difficulty from the container on which it is affixed.

Appl. No.:

5/633315

Inventors:

Walter F. Anderson - West Covina CA

Assignee:

Diamond International Corporation - New York NY

International Classification:

B05B 100

US Classification:

222321

Abstract:

A dispensing pump having upper and lower pistons defining opposite ends of a two diameter pump chamber, the volume of which is varied by movement together of the pistons, while a small amount of relative movement of the pistons, resulting from pressure changes within the pump chamber, effects opening and closing of the discharge valve. For facilitating the priming of such a pump, the lower piston and cylinder are arranged to define a normally closed priming valve operable at a predetermined point in the lower piston stroke to permit reverse flow of entrapped air from the pump chamber into a liquid supply container with which the pump is associated.

Appl. No.:

6/938841

Inventors:

Walter F. Anderson - West Covina CA
Richard P. Grogan - Downey CA

Assignee:

Calmar, Inc. - Watchung NJ

International Classification:

B67D 532
B65D 4132

US Classification:

222153

Abstract:

A liquid dispenser has a closure cap for mounting the dispenser on a liquid container, and a non-removable tamperproof overcap secured to the closure cap. The overcap has a line of weakening to facilitate overcap separation to gain access to the dispenser actuator. And, the closure cap has a tamperproof ring.
