A cartridge (12) for a viscous-material dispenser includes a plunger (10) that is slidable within a cylinder (18). A seal body (104) forms between an outer circumferential surface (82) of the plunger and an inner circumferential surface (84) of the cylinder when a viscous material flows into a radial tubular clearance (106) that continuously extends both axially and circumferentially between the outer circumferential surface and the inner circumferential surface. Ridges (100) may be formed on the outer circumferential surface of the plunger to guide the inflowing viscous material and facilitate the formation of the seal body.

A method is provided for filling a bag-on-valve can with a hypochlorous acid solution, including: providing a hypochlorous acid manufacturing apparatus having an anolyte storage tank in which the hypochlorous acid solution is stored; providing a bag-on-valve canning apparatus having a fluid inlet; connecting a pipe between the anolyte storage tank of the hypochlorous acid manufacturing apparatus and the fluid inlet on the bag-on-valve canning apparatus in order to provide the hypochlorous acid solution directly from the hypochlorous acid manufacturing apparatus to the bag-on-valve canning apparatus; providing a bag-on-valve can having a can in which a bag and a valve are disposed, wherein the valve seals the bag during non-use, the bag-on-valve can further including an actuator for actuating the valve; and filling the bag with the hypochlorous acid solution provided through the pipe. An apparatus is also disclosed for producing and canning a hypochlorous acid solution.

A fuel canister valve assembly has a valve cup, a valve stem housing connected with the valve cup and defining a seal housing containing a valve seal and a valve stem having an inner end housed in the valve stem housing and extending through the valve seal to an outer end disposed externally of the valve stem housing. The valve stem housing has an outer periphery provided with at least one side passage defining a flow path along the outer periphery.

A carbonation machine may include a carbonation head, a holder that is configured to hold a gas canister, the holder comprising a connector with a socket configured to enable linear insertion of a valve of the canister into the socket, the socket including a seal with at least one lateral opening to enable fluidic flow between one or more laterally oriented ports of the valve and a conduit of the holder while preventing leakage of gas from the fluidic flow, and a holding mechanism configured to hold a lateral projection from the canister after insertion of the valve into the socket such that the valve remains in the socket, and an activation mechanism configured to operate the valve to release the gas from the canister when inserted into the socket so as to enable the gas to flow via the conduit to the carbonation head

A valve assembly for a pressurized container includes a valve stem and a mechanical seal. The valve stem has an open top portion, a closed bottom portion, at least one primary radial opening, at least one secondary radial opening and a valve stem passageway between the open top portion and both the at least one primary radial opening and the at least one secondary radial opening. The mechanical seal comprises a longitudinal passageway that seals the at least one primary radial opening and the at least one secondary radial opening, respectively, when the valve stem is in a closed position. Longitudinal translation of the valve stem exposes the at least one primary radial opening or both the at least one primary radial opening and the at least one secondary radial opening to the pressurized container when the valve stem is in an open position.

A stem (1) for a two-way valve has a main body (10) outer face that is substantially cylindrical about a main axis, with (i) a first tubular wall (11) closed at its lower end by a first bottom wall (13) and open at its upper end (111), defining a central
channel (113); (ii) a second tubular wall (12), concentric with the first tubular wall (11) and partially surrounding it, closed at its lower end (122) by a second bottom wall (14) and open at its upper end (121), defining an annular channel (123) around the central channel (113), one or more through-holes (124) bringing the inside of the annular channel (123) in contact with the cylindrical outer face of the main
body (10); and (iii) a tubular insert (20) dimensioned so as to be able to be inserted into the annular channel (123).

The invention comprises a method and apparatus for holding a Cannabis product, such as a beverage container having a resealable closure that remains affixed to the beverage container when in both an open position and a closed position, where a cavity within the container comprises at least two servings of tetrahydrocannabinol (THC). The resealable closure optionally includes a slideable/rotatable element that is slideable/rotatable along a horizontal plane relative to an upper surface of the beverage container, the slideable/rotatable closure element alternatingly closing an opening in the lid when in a first position and allowing access through the opening when in a second position. The resealable container in combination with graphical THC serving size indicators allows a consumer to consume a known amount of THC.

An adapter for a canister filling system includes a body having an opening that is shaped to enable insertion of a valve of a gas canister for holding a pressurized or liquefied gas, into an interior space of the body, leaving a sealed gap between at least a portion of a lateral aspect of the valve and an internal surface of the body facing the interior space; and at least one channel that is configured to conduct pressurized or liquified gas from a canister filling system into the sealed gap in the interior space, so as to reach one or more lateral exterior ports of the valve of the gas canister that open laterally to a longitudinal axis of a body of the gas canister, when the valve is inserted in the interior space, to facilitate filling of the gas canister with the pressurized or liquified gas through said one or more lateral exterior ports of the gas canister.

The invention comprises an apparatus, comprising: (1) a dissolvable tablet, comprising: a support matrix, the support matrix comprising at least two percent by mass a gassing agent, the gassing agent comprising at least one of: a carbonic acid, H.sub.2CO.sub.3; a bicarbonate, HCO.sub.3; a bicarbonate salt; a carbonate, CO.sub.3.sup.2−; and a carbonate salt; and (2) at least one milligram of tetrahydrocannabinol, where the dissolvable tablet optionally includes an acid and a buffer at least partially separating the gassing agent and the acid, where the tetrahydrocannabinol is blended into the support matrix of the dissolvable tablet prior to formation of the dissolvable tablet and/or is infused into a pre-made tablet comprising the support matrix.

The present device dispenses product from a pressurized container. The device has a metered valve that dispenses a predetermined fixed quantity of product upon actuation. The metered valve can be configured by the customer with a spacer to affect the amount of product continually metered.
