The present disclosure provides a cup lid and a self-producing water cup. The cup lid includes: a housing, a condensing mechanism, and a heat dissipation mechanism. The housing defines a housing space, an air inlet, an air outlet, and a water outlet. The air inlet, the air outlet, and the water outlet are connected to an outside. The air inlet, the air outlet, and the water outlet are connected to the housing space. The condensing mechanism is housed in the housing and connected to the air inlet. The condensing mechanism is configured to condense air flowing from the air inlet into water, and the water flows out through the water outlet. The heat dissipation mechanism is housed in the housing and connected to the air outlet. The heat dissipation mechanism is configured to dissipate heat generated by the condensing mechanism.

Embodiments include a cooling device for a medical device. The cooling device including a controller configured to receive data from one or more temperature sensors and a pump, configured to be operated by the controller, to circulate a cooling fluid through a cooling system and through fluid channels in the medical device. The cooling device is configured to be worn by a user and to be selectively coupled to the medical device by the user.

A bottom-fill hydration bottle includes a main body having a valve assembly positioned along the bottom end. The valve assembly including an inlet opening, a valve, an outlet opening and a deflector. The deflector includes an input opening and at least one aperture that functions to discharge the received fluid in a direction that is different than the outlet opening of the valve. The hydration bottle includes a cap that is selectively coupled to the top of the main body. The cap includes a central spout having a bottom opening and an upper opening. A diffuser is positioned along the bottom opening of the spout. The diffuser including an output opening and at least one aperture that functions to receive fluid from the main body at an angle that is different from the bottom end of the spout.

An apparatus includes an exterior portion, an interior portion, a first top, and a second top. The exterior portion includes an exterior wall, an exterior top end coupled to the exterior wall, and an exterior bottom closed end coupled to the exterior wall. The interior portion nests within the exterior portion and includes an interior wall having a geometry smaller than the exterior portion, an interior bottom closed end coupled to the interior wall, and an interior top end coupled to the interior wall opposite the interior bottom closed end. The first top closes the interior top end to form an interior space within the interior portion. The first top includes a first opening. The second top includes a second opening. The second top engages with the exterior bottom end in a stored position and engages with the exterior top end in a containing position.

An insert made from reticulated foam has a first profile in which an outer perimeter of the insert has a size and a shape that substantially corresponds to an inner surface of a portable container. The insert also has a second profile in which the outer perimeter of the insert has a size and a shape that substantially corresponds to an opening of the portable container. The reticulated foam has a cell density that prevents sloshing noises resulting from jostling movement of the portable container from exceeding 50 db while enabling liquid to exit the portable container at a consumable rate.

A hydration pack includes a main body, a strap, a bladder, a hydration tube, a first chain of magnets, and a second chain of magnets. The main body defines a storage compartment. The strap is coupled to the main body. The bladder is disposed in the storage compartment of the main body and configured to retain liquid. The hydration tube includes a proximal end coupled to the bladder and a distal end. The first chain of magnets is disposed on the strap. The second chain of magnets is disposed along a length of the hydration tube. The first and second chains of magnets are configured to connect by magnetic forces and disconnect by a force exceeding the magnetic force of the first and second chains of magnets.

The invention relates to portable liquid supply device, mainly for water from central and other sources or for suspensions, for example pharmaceutical products and nutrient liquids. The invention can be used in household, outdoors, in the garden plots, in health care institutions, for example, for patients with dysphagia, as the source of purified drinking water or nutrient liquids, which go to a patient easily. Liquid supply device, includes raw liquid vessel, pressure generating means, liquid treating unit, comprising a lid, liquid supply means, liquid treating element and raw liquid inlet element, characterized in that is configured to supply treated liquid in portions from 5 to 100 ml, with velocity 0.5 to 10 ml/sec.

An improved container for storing liquids includes a main body. The main body includes a front surface, a rear surface, a left side surface, a right side surface, a top surface, a base surface, and plurality of cylindrical surfaces. The top surface includes an aperture adapted to allow liquids to pass therethrough. The front surface, the rear surface, the left side surface, the right side surface, the top surface, and the base surface form an interior volume adapted to retain liquids therein. The plurality of cylindrical surfaces extend between the left side surface and the right side surface.
