Torch

A method for removing a child-resistant spout closure cap from a spout on a container and a child-resistant spout closure for a container configured to hold either a liquid or a solid material, with the container including a fill opening to the interior of the container and an elongated hollow spout having a distal end and a proximate end, with the proximate end configured to align with the fill opening of the container. The child-resistant spout closure comprises a lip formed on the distal end of the spout defining a spout opening in fluid communication with the interior of the spout, with the lip having a closure recess extending through the lip to a spout wall; and, a cap configured to fill the spout opening. The cap has a lock nub configured to engage the lip and seal the spout opening and selectively pass through the closure recess when the lock nub and the closure recess are aligned. When the lock nub and the closure recess are aligned, the cap is removable from the spout.

Child resistant spout closure

A spout for a container comprising a conduit having a first end connected to the container, an aperture and a second end configured to be inserted into an opening. The second end of the conduit is configured to direct fluid axially out of the second end of the conduit. A closure plate extending across the diameter of the conduit for preventing flow through the conduit is provided. The closure plate has a closed position to inhibit flow through the conduit in an open position to allow flow through the conduit. A sleeve movably responsive to inserting the conduit into the opening moves the closure plate from the closed position to the open position. The sleeve is spring loaded to hold the closure plate normally closed. A vent tube having a passage is coupled to and supports the closure plate centrally disposed in the conduit. The vent tube has an inlet and an outlet with the inlet disposed in the aperture and opens into the conduit and the outlet disposed co-terminus with the second end of the conduit and permitting a flow of air from the inlet into the vent passage during a flow of fluid from the container into the opening. An end cap is coupled to the vent tube at the inlet and configured to fluidly seal the conduit in conjunction with the closed position of the closure plate.

A process for blow molding a hollow plastic product comprises introducing a hollow elongated parison of thermoplastic material between a pair of opened sections of a blow mold, and then closing the mold. The mold sections are closed along a linear direction of travel and, when closed, form a mold cavity including a narrow section extending in the direction of travel. The narrow section has a width less than about twice a wall thickness of the parison. As the mold sections close, they sever and enclose a segment of the parison within the mold cavity and shear a double-wall section of the parison into the narrow section to form a reinforcing flange on the product. Upon closing of the mold, a predetermined pressure is provided to an interior of the parison to expand the parison against internal surfaces of the mold cavity to form the remainder of the product. A mold for use in blow molding a hollow plastic product and a one-piece hollow plastic product made by the blow molding process are also disclosed.

The invention provides a vent cap for automatically discharging a gas container such as a propane cylinder. The vent cap includes threads for securing the vent cap to the neck of the gas container. The vent cap further includes an indicator which has a pin and a button. When the button is manually depressed, the pin engages the valve stem of the check valve which seals the gas container, discharging gas from the container. The button includes a flexible, radially curved central portion which provides oil can action when the indicator is moved between the up position and the down position. A geometrical configuration of the central portion may be adjusted to vary the gas pressure threshold at which the indicator will remain in the down position to automatically discharge a nearly empty gas container.

The invention provides a container for collecting, storing and transporting a liquid. The container includes a hollow container body having a top wall having a central, inwardly directed fluid directing portion and an opening in the fluid directing portion for permitting liquid collected in the fluid directing portion to pour into the hollow container body. The container also has a spout sized for pouring out liquid collected in the container body. A roller assembly on an underside of the container body permits rolling movement of the container body along a supporting surface. The container also has suitable means such as bearing grooves for securing the roller assembly to the container body.

Component parts of a steel container for storing a gas, specifically a mixture of stabilized methylacetylene and propadiene (C.sub.3 H.sub.4), are joined by a brazing alloy consisting of about 48% to 67% by weight copper; about 4.5% to about 7% by weight phosphorous and the balance nickel. During manufacture of the container, component parts may be joined either by brazing the joint with the specified alloy in wire or rod form or by applying to the joint a brazing paste comprising the specified metals unalloyed in powdered form and heating the joint in a furnace to melt and alloy the metals to form the joint. The brazing alloy has desirable metallurgical characteristics and is nonreactive to exposure to the specified gas stored in the container. The brazing paste has characteristics which enhance its utility for mass production techniques.

A torch for use with a portable tank of pressurized liquified combustible gas, such as MAPP type gas, comprises a regulator valve assembly, including a valve body having a gas outlet therein, and a burner assembly, including a combined burner tube, venturi member and orifice member, which is releasably and adjustably connected in sealed relationship to the outlet on the valve body by frictional retaining means so as to enable quick and easy pull-out and push-in substitution of different-sized burner assemblies, while still allowing for rotational adjustment or positioning of an installed burner assembly.
