A refillable vessel uses light from an external source such as a portable LED flashlight to illuminate the interior of the vessel to determine the level of the vessel contents without the need for separate sight windows in the wall(s) of the vessel. At least the sidewall of the vessel incorporates a one-way or semi-silvered mirror that visually obscures the contents of the vessel until illuminated with the external light source. The one-way mirror is preferably implemented with a metallized film. A portion of the bottom of the vessel may be used for illuminating the interior of the vessel. The vessel may be supported in a bracket with an opening that aligns with an illumination region, window or port. The contents of the vessel may include a liquid, a cream, or a gel comprising a personal hygiene product used in the hospitality industry, for example.

The tumbler bottle includes a cup having a side wall interior surface and bottom wall a convex interior surface. The cup side wall and bottom wall interior surfaces are joined by a smooth, arcuate interior transition surface to define a first mixing chamber. The tumbler bottle further includes a lid, removably connected with the cup. The lid includes a side wall interior surface and a top wall concave interior surface. The lid side wall and top wall interior surfaces are joined by a smooth, arcuate interior transition surface to define a second mixing chamber. The lid further includes a dispensing outlet and a closure. When coupled together the first mixing chamber and the second mixing chamber are in fluid communication and are configured to uniformly mix a liquid with one or more additives.

Further, the container may include a bottom side, a first imprinted surface, a second imprinted surface, a plurality of side surfaces and a cavity. Further, the first imprinted surface may include a first imprinted media. Further, the second imprinted surface may include a second imprinted media. Further, the bottom side may include a plurality of vertexes. Further, the cavity may be configured for storing an item. Further, the seal may be configured for preventing access to the cavity. Further, the seal may include a male side and a female side. Further, a male side of the seal may be located on a first member of the plurality of top edges. Further, a female side of the seal may be located on a second member of the plurality of top edges.

Embodiments are directed to a dispensing device and methods of using a dispensing device having an improved out indicator. The dispensing device includes a housing having a cavity. A tissue stack is disposed within the cavity, the tissue stack including a plurality of tissue sheets folded along a crease. An aperture is formed in a top surface of the housing such that a tissue sheet is removable from the cavity through the aperture. A portion of the tissue sheets includes an out indicator formed along a centerline of each tissue sheet and across the crease.

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.

The present disclosure reveals a level indicator for use with storage tanks on motorhomes or campers. The level indicator comprises a sensor attached to the bottom of a storage tank in order to allow easy access to replace the sensor in case of failure. The sensor is calibrated to indicate the amount of liquid above the sensor in the tank. As the level of the tank changes, a readout meter indicates the volume of liquid present by percentage.

The present invention relates to a container with a side wall of plastic encloses a container volume. Horizontally oriented grooves spaced vertically apart from one another are formed in the side wall, and the grooves include first grooves for stiffening the side wall. The first grooves have a first groove depth and are configured such that a projection protruding into the enclosed container volume is formed in the inner surface of the side wall. The grooves also include second grooves having a second groove depth. The first groove depth is greater than the second groove depth. The first and second grooves are arranged such that at least one second groove is in each case arranged in the vertical direction between two first grooves. The subvolumes enclosed by two horizontal planes, which are defined by two adjacent grooves, and the side wall are in each case identical.

A beverage container lid can include an audio speaker; a wireless transceiver to transmit and receive wireless signals; and a hardware processor to process wireless signals received by the wireless transceiver and to output audible signals through the audio speaker. The beverage container lid can also include a water-tight housing, the wireless transceiver and hardware processor contained within the water-tight housing; a drinking aperture; and a fluid channel, the fluid channel to allow fluid to pass through the drinking aperture, and the water-tight housing to prevent fluid passing through the fluid channel from contacting the wireless transceiver and hardware processor.

A personal container for hydrating liquid. The container has a inner cup containing an adjuvant that is selectively introduced into the liquid in the container. The base contains electronic means to digitally measure the quantity of liquid in the container. The electronic means measures the time relative to the quantity of liquid to ensure a sufficient volume of liquid is consumed at a pre-specified rate.

A measured fluid dispenser for dispensing fluid from a storage container includes a measurement chamber, a fluid flow passage fluidly connecting the measurement chamber with the storage container, and a valve that is movable between an open position in which the fluid flow passage is opened to permit fluid flow from the storage chamber to the measurement chamber, and a closed position in which the fluid flow passage is closed to prevent fluid flow between the measurement chamber and the storage chamber. The measurement chamber may be adjustable to vary a fillable volume of the measurement chamber to thereby preselect an amount of fluid to be dispensed.
