A degradable containment includes an outer structural layer constructed of a pulp material, a central carrier layer constructed of a biopolymer, and an interior nanomaterial layer constructed of a nanomaterial.

A fluid timer configured to receive fluid therein when the timer is in a first orientation and to emit fluid along a timer vertical axis during pre-determined time when the timer is in a second, reversed orientation.

A fluid timer configured to receive fluid therein when the timer is in a first orientation and to emit fluid along a timer vertical axis during pre-determined time when the timer is in a second, reversed orientation.

An apparatus comprising a straw and a one-way valve. The straw can include a top end, a straw body, and a bottom end opposite the top end and configured to be placed in a container. The one-way valve can be removably coupled to the bottom end of the straw and configured to allow liquid in the container to enter the straw when a suction force is created at the top end of the straw. Other embodiments are disclosed.

An integrally formed cap has a flat circular surface, an internally threaded cylindrical sidewall extending from the surface in a first direction; a semicircular spacer extending from the flat surface in a second, opposite direction; and a circular frame joined to the semicircular spacer. The frame is parallel to the flat surface. The spacer and the frame form a gap. A removable disc, such as a collectible coin or poker chip, may be inserted into the gap through the side of the cap.

When a known lid member was merely applied to a bottle that contains ink, there was room for improvement in terms of the operation of the lid member and the way how to bring attention to the handling thereof. A bottle set is provided that includes: a bottle that includes an ink container that contains ink, and an outflow port through which the ink in the ink container flows out to the outside; and a lid member that is configured to attach to and detach from the bottle, and is configured to cover the outflow port in a state of being attached to the bottle. The lid member includes a colored portion that has optical transparency and is colored with a color corresponding to a type of the ink contained in the ink container in at least a portion of the lid member.

A cap includes an upper cap portion to enclose an opening of a bottle and hold a dosage of fluid, a lower cap portion to extend into the bottle and increase the dosage capacity of the cap, and a skirt configured to engage the exterior surface of the bottle to secure the cap to the bottle. The upper cap portion includes a top and a first sidewall having one or more sections that protrude radially away from other portions of first sidewall.

A threaded tumbler bottle cap includes a cap handle, a cap base, and a strainer. The cap base includes a flange, an annular wall, an opening, and a lateral wall. The lateral wall that threadedly attaches to a tumbler is perimetrically connected around the annular wall. The opening that allows the stored beverage to flow through concentrically traverses through the annular wall. The flange is concentrically positioned around the opening and externally connected onto the annular wall so that the stored beverage can be discharged from the tumbler. The strainer is internally engaged within the flange to keep the ice cubes within the tumbler. The cap handle is threadedly engaged around the lateral wall as the annular wall and the flange being enclosed by the cap handle. The flange is hermetically pressed against the cap handle thus preventing any leakage of stored beverage.
