A cap comprising a cap body including a top plate portion which is disk-shaped, and a skirt portion which is cylindrical and provided at a peripheral edge portion of the top plate portion, the top plate portion including a substrate and a resin coating film provided on a cap inner surface side of the substrate, the resin coating film including a polyester-based resin and a lubricant, and a sealing member provided in the cap body separately from the cap body so as to face the top plate portion, and having an outer diameter smaller than an inner diameter of the skirt portion.

The present disclosure is directed to an apparatus, system, or method for covering and utilizing a plunger. The plunger can be inserted into a cover configured or sized to receive the plunger. The cover is attached to a handle with a closure mechanism. The closure mechanism is used to close the open end of the cover after removal of the plunger from the cover. A toilet or other drain or pipe system may be unclogged using the covered plunger. When the plunger and the cover are removed from a toilet, and the plunger is removed from the cover, the cover reverses or inverts. When reversed or inverted, the cover contains water or waste material from the toilet within the cover.

A new light protective closure that includes a wall portion(s) and a top plate. The top plate is provided with an at least partial supplemental light protection layer in addition to the light protection provided by the material used to form the top plate.

Described herein is a coupling device configured to be mechanically coupled to a cap of a container to be in a coupled configuration. Also described herein are a corresponding method and a corresponding system. In one embodiment, the coupling device is used in combination with a crop protection spray system. The coupling device includes a single probe and a first and a second mechanical mechanism. The first and the second mechanical mechanisms are independent from each other. The first mechanism allows drawing the cap and the container towards the coupling device thereby sealing and locking the cap and the coupling device into a desired position. The second mechanism facilitates actually moving the probe thereby lifting the probe with the closure insert into the container. The coupling device may be embodied as a first, second and third tube which are arranged concentrically.

A capping structure includes a tubular shell and a cap window. The cap window is transparent and engages with an inner sidewall of the tubular shell. The cap window includes a cover and a brace. The cover is disposed at an opening of the tubular shell, and the brace protrudes from the cover and has at least a surface being parallel to the inner sidewall of the tubular shell.

An identity of a container coupled to a content level sensor device is received. A plurality of signal parameters associated with the container is identified. The signal parameters are transmitted to the content level sensor device, wherein the signal parameters are indexed according to a level of content in the container.

Apparatus for ensuring adequate sunscreen protection includes a light-activated sunscreen product, and an illuminator including a battery, a switch and a light source that causes the light-activated sunscreen product to glow when illuminated with the light source. The light-activated sunscreen product may include a zinc-oxide-based lotion and a fluorescent substance such as fluorescein dye causing the lotion to glow in any available color when applied to the skin and illuminated by the light source. The closure may be a cap with a threaded attachment to the container, and the light source may comprise one or more ultraviolet light-emitting diodes. The illuminator may be disposed in a cap with top and side surfaces, and the switch may be positioned on the side of the cap, and the light source on the top of the cap, or vice versa. The switch is preferably a momentary contact switch.
