Disclosed herein are systems and methods for a container having a base that includes an outer wall, an insulation layer, and an inner wall. The container further includes a movable lid connected to the base, and a plurality of spigots are coupled to a front wall of the base at a second end thereof. The second end is opposite the first end, the front wall is opposite a rear wall, and the front wall is connected to the rear wall by a pair of side walls. A plurality of flow channels are formed in the inner wall of the base, and the plurality of spigots are fluidly coupled to the plurality of flow channels.

An overmolded preform and a container blow molded from the same are disclosed, wherein the overmolded preform and the overmolded container include an inner foamed layer.

A formulation for producing a polymeric material including polypropylene, a chemical blowing agent, and optional components as described.

A double-layer extruded bottle comprises an inner cup, an outer cup connected to the inner cup, an interlayer gap disposed between the inner cup and the outer cup, and a first insulation layer disposed in the interlayer gap and on an outer peripheral surface of the inner cup. The first insulation layer is integrally formed with the inner cup by an in-mold lamination process. A manufacturing method for the bottle includes forming the first insulation layer and a second insulation layer by in-mold lamination, pattern printing, punching and shaping, blow molding, and assembly and welding of the inner and outer cups. The extruded bottle has a double-layer structure that improves the heat preservation performance. The integrated molding method shortens the production cycle and reduces the production cost. Decorative patterns can be printed on outer surfaces of the insulation layers.

A water cup with a self-locking function includes a cup body, a suction nozzle portion, a casing and a cup cover. The suction nozzle portion is connected to the cup body, and the suction nuzzle portion is arranged with limit teeth and an outlet pipe. The casing is sleeved on the suction nozzle portion and is penetrated by the outlet pipe. The casing is internally arranged with a clamping plate with a limit buckle and a toggle block, and the toggle block is capable of driving the limit buckle to be clamped with or disengaged from the limit teeth. The cup cover is connected to the casing and is arranged with a signal receiving unit, a driving member and a snap, and the signal receiving unit is capable of activating the driving member to drive the snap to be clamped with or disengaged from the snap position on the casing.

A soft toy hydration system for incentivizing hydration, the system including a liquid container, such as a removable bottle, and a soft outer sleeve configured to envelop the container, the sleeve including an outer fleecy skin layer shaped into a decorative form attractive to children, such as a stylized animal or beverage, where a drinking outlet from the container, such as a straw, protrudes through an upper aperture in the sleeve for access, where the sleeve may further include a closable access opening, such as a zipper, to facilitate removal of the container for cleaning or refilling.
