Publication number: 20220250106Abstract: A pump dispenser comprises an actuator head (100) having a dispensing channel communicating with a nozzle outlet (122), a closure body (20) having a top facing (203), at least one engagement feature extending axially upward from the top facing, and a recess (210) formed in the top facing. The recess has a cylindrical sidewall (212) with a plurality of axially-aligned stoppers positioned along the cylindrical sidewall and an annular ledge (220) defining an inlet port at a bottom end of the recess, said ledge including a cylindrical abutment (240) extending axially upward within the recess (210). An internal plug (40) is positioned within the annular recess, and includes an annular disk (400) with at least one axially-aligned stopping flange (410) positioned at or around a periphery of said disk and a plurality of axially-aligned engagement flanges (420) positioned toward a center of said disk.Type: ApplicationFiled: July 23, 2020Publication date: August 11, 2022Inventor: Simon Christopher KNIGHT

Publication number: 20220176396Abstract: A universal closure for a dispenser is contemplated. The closure seals to the container neck along three separate surfaces with sufficient force to enable the use of lockdown and/or anti-rotational features to secure the dispenser for e-commerce shipments. Provision of frictional projections secures a sufficiently tight fit between the container neck and the body insert of the closure so as to eliminate the need to force separate engagement features on the container itself.Type: ApplicationFiled: March 26, 2020Publication date: June 9, 2022Inventor: Simon Christopher KNIGHT

Publication number: 20220097090Abstract: 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: ApplicationFiled: November 15, 2021Publication date: March 31, 2022Inventors: Simon Christopher KNIGHT, Gaurang MITTAL

Patent number: 11173506Abstract: Pump dispenser comprising a pump and a container for liquid to be dispensed, the pump comprising a pump body mounted in the neck of the container and a plunger reciprocable relative to the pump body to alter the volume of a pump chamber defined in the pump body and having an inlet and an outlet, the outlet leading through an outlet passage to a discharge opening. The pump cylinder body is retained at the container neck. A vent is provided in the cylinder body wall adjacent the neck edge. A vent block ring is disposed in the cylinder body adjacent the vent, and is moveable between blocked and unblocked positions relative to the vent. The vent block ring has an integral upward projecting formation which is engaged by part of the plunger in a locked-down position of the plunger, so that when the plunger is locked down the vent block element blocks the vent, while in a relatively extended position of the plunger the vent block element is in the unblocked position.Type: GrantFiled: November 9, 2018Date of Patent: November 16, 2021Inventor: Simon Christopher Knight

Publication number: 20210346899Abstract: A dispenser pump is constituted by a closure body (2), a diaphragm body (3) which forms a pump chamber with the closure body and optionally a top actuator (4) for pressing the diaphragm body (4). The diaphragm body has a deformable wall (35) formed integrally in the same polymer as its annular mounting portion (31). An inlet valve (5) through the floor (21) of the closure body has a flap (52) which is formed and hinged integrally with that floor (21). An outlet valve may also be formed in the same polymer, either integrally with the diaphragm body or as a separate component. The deformable wall of the diaphragm body is shaped to generate a restoring force itself without a separate spring, so that the entire pump may be made from the same polymer e.g. polypropylene and without metal components.Type: ApplicationFiled: May 24, 2021Publication date: November 11, 2021Inventor: Simon Christopher KNIGHT

Patent number: 11117147Abstract: A dispenser for dispensing a flowable product from a container has a pump module mounted on the container at an opening thereof. The pump module includes a pump body, which defines a pump chamber and a pump chamber inlet for product to flow from the container interior into the pump chamber. A pump actuator is operable in a pumping stroke relative to the pump body to vary the volume of the pump chamber and dispense the product. The pump includes a movable body portion which is operable in a displacement stroke into the container. The movable portion has a displacement body with a product-engaging face directed onto an interior product space of the container upstream of the pump chamber inlet, to assist priming. Below this a disrupter member, a grid of narrow bars, projects to penetrate the product.Type: GrantFiled: November 4, 2019Date of Patent: September 14, 2021Inventors: Simon Christopher Knight, David John Pritchett, Thomas P. Kasting, Mark Edward Box, Raymond Yu

Publication number: 20210260609Abstract: 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 outer body and providing an external collar through which the plunger stem operates. 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: March 22, 2021Publication date: August 26, 2021Inventors: Simon Christopher Knight, Gaurang MITTAL, Ashish SINGH, Pratham PAL

Patent number: 10723527Abstract: A dispensing closure for dispensing fluid product from a squeeze container consists of an outer cap element (3) and an inner element or valve disc (4) fitting inside the cap element. Each is moulded from thermoplastics; no elastomer is used. The cap element includes an outwardly-deflectable diaphragm wall (35) around a central outlet opening (361). The inner element (4) has a peripheral mounting ring (41), a central blocking portion (48) and a set of support spokes (46) providing flow clearance between them. In a closed position the blocking portion closes the outlet opening. In an outflow condition the diaphragm wall (35) deflects outwardly to allow flow. In a recovery mode the blocking portion (48) deflects inwardly for compensation air or residual liquid product to enter the container.Type: GrantFiled: April 8, 2019Date of Patent: July 28, 2020Assignee: RIEKE PACKAGING SYSTEMS LIMITEDInventor: Simon Christopher Knight
