Patent number: 11772112Abstract: A dispensing pump capable of withstanding the rigors of “e-commerce” shipping conditions is described. The pump dispenser is integrated with the container's closure. The pump includes a lock-down mechanism to prevent the pump actuator from extending during shipment, while a vented chaplet and an optional beaded seal proximate to the dip tube connection ensure that fluid cannot leak out of the container or the pump.Type: GrantFiled: April 2, 2020Date of Patent: October 3, 2023Inventor: Gaurang Mittal

Patent number: 11691168Abstract: A dispenser pump has a plunger operable in a body including an outer cylinder body having a vent opening in its sidewall and a body insert fitting into the top of the body cylinder and providing an external collar through which the plunger stem operates. The body insert has a lock-down thread to lock down the plunger for shipping. The insert also has an undulating annular vent-control bead extending right round its cylindrical outer surface, engaging the cylinder wall with interference for either blocking or unblocking the vent opening, according to whether the vent-control bead lies above or below the interior vent opening, by rotation between the body cylinder and body insert. The rotation can be driven by rotation of the plunger head, which makes a catch engagement with the top of the body insert. Blocking the vent during shipping reduces leakage.Type: GrantFiled: November 15, 2021Date of Patent: July 4, 2023Inventors: Simon Christopher Knight, Gaurang Mittal

Publication number: 20230036640Abstract: A reciprocating foamer pump avoids problems encountered when conventional foamer pumps are exposed to freezing temperatures. In particular, the inventive pump provides an extra-secure connection between air and liquid piston members (200,300). Additionally, a tortuous air inlet (210) is provided to the foamer chamber (136) so as to prevent melted liquid from draining and accumulating in the air chamber.Type: ApplicationFiled: December 31, 2020Publication date: February 2, 2023Inventors: Gaurang MITTAL, Simon Christopher KNIGHT, Manuj SHARMA

The body insert has lock-down threads to lock down the plunger for shipping. The insert also has formations for blocking or unblocking the vent opening by rotation between the outer body and body insert, driven by rotation of the plunger head which makes a catch engagement with the top of the body insert. This plunger head rotation is the locking or unlocking action for the plunger lock-down. Blocking the vent during shipping reduces leakage.Type: ApplicationFiled: August 15, 2022Publication date: February 2, 2023Inventors: Simon Christopher Knight, Gaurang MITTAL, Ashish SINGH, Pratham PAL
