A liquid storage tank broadly comprising a drum, a bottom chime, and a top chime. The bottom chime and top chime each include drum engaging geometry for positively connecting the chimes to the drum and retaining the chimes on the drum when the drum is holding liquid and subjected to lifting forces. The top chime also includes forklift openings and alignment and anti-rotation geometry configured to prevent the top chime from rotating relative to the drum when the drum is lifted via a forklift fork extending through the forklift openings so that the forklift fork does not damage a top wall or bung openings of the drum.

This invention provides a liquid container apparatus and method to prevent spilling of a liquid, such as oil, while adding liquid to an engine or other component, without the use of a funnel and without inverting the container, and to make the liquid-adding operation easier and safer for a user, providing a smart cap with a smart-cap opening turnably mounted upon an opening protrusion on a container body such that the smart cap can be closed and opened without detaching the smart cap from the container body, the liquid can be dispensed without inverting the container, and the rate of liquid flow can be controlled by a user, providing a container able to be placed upon or near an engine for the required time, providing a container that dispenses liquid without being inverted, and providing a container that visually indicates the amount of liquid within, consequently simplifying the use of the container.

An animal trap sensor includes a base having a distal end and a proximal end, a switch having a first metallic element and a second metallic element, and a signal unit, in which, when the first metallic element contacting the second metallic element, thereby forming a closed circuit, such that the signal unit transmits a signal to an off-site receiver. Or, an animal trap sensor includes a first portion and a second portion electrically connected with a signal unit including a power supply, in which, when the first and the second portions are disposed at a first distance between each other, thereby generating an output property, in which, when the first and the second portions are disposed at a second distance between each other, which is different from the first distance, thereby changing the output property and causing the signal unit to transmit a signal to an off-site receiver.

A container system has a plurality of separable interlocking vessels. Each of the vessels defines a separately sealed volume. Each of the vessels has an outlet. One of the plurality of the vessels is an upper vessel and one of the plurality of vessels is a lower vessel. The outlet of the upper vessel is the lowermost portion of the upper vessel and is disposed to one side of the upper vessel. The outlet of the lower vessel is the uppermost portion of the lower vessel and is disposed to one side of the lower vessel.

A drawn and wall ironed beverage can body, method for forming same, and a sealed and filled can, include a through-hole or aperture in the base. A grommet for charging a propellant in can is located in the aperture. The aperture has a burr that is located on the inboard side of the rim of the aperture. A method of forming a valve in the drawn and ironed beverage can body includes positioning a first tool in an interior of the can body, contacting an exterior surface of the base with a second tool such that the first and second tools are aligned, forming the aperture in the base, and inserting the grommet into the aperture.

A stackable container system is configured to provide stacked receptacles for receiving bulk material therein. The stackable container system includes a first receptacle configured to provide a respective stacked receptacle. The first receptacle includes a receptable bottom, a receptable top, and a receptacle side extending along an upright container axis between the receptacle bottom and top, with the first receptacle presenting a container chamber. The receptacle top is configured to at least partly support another one of the stacked receptacles stacked relative thereto along the upright container axis. The receptacle top and the receptacle side have, respectively, a top peripheral margin and a side peripheral margin that extend laterally about the upright container axis, with at least part of the top peripheral margin being laterally outboard of the side peripheral margin. At least part of the top peripheral margin is interconnected to the side peripheral margin along a transition section that extends laterally between the receptacle top and the receptacle side.

A container includes a receptacle including an upright receptacle side and a receptacle bottom that cooperate to at least partly define a container chamber. The bottom presents a peripheral margin, with the side being attached to the bottom along the peripheral margin and extending upwardly relative to the bottom along an upright container axis. The receptacle further includes a drain configured to permit material flow out of the chamber, with the drain intersecting the bottom to define a drain opening that fluidly communicates with the chamber. The drain opening is spaced inboard from the peripheral margin and is laterally offset from the container axis in an offset direction. The bottom includes first and second floor sections extending inboard from the peripheral margin and joined relative to each other along a first gutter area adjacent the drain opening. The first floor section slopes downwardly toward the first gutter area in the offset direction and the second floor section slopes downwardly toward the first gutter area in a direction opposite the offset direction, with the floor sections configured to cooperatively advance material within the chamber toward the drain opening.
