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.

Flexible containers are provided herein. In some embodiments, the flexible containers include a front panel, a back panel, a bottom panel, and a top panel attached to form a pourable material storage area, wherein the front panel and the top panel include a hole in the front panel and the top panel to form a dispensing system passage, and wherein the dispensing system passage is not in fluid communication with the pourable material storage area. A dispensing system is attached to the top panel between the top panel and the back panel and extends through the dispensing system passage.

A closure assembly for a dispenser container comprises a base defining a longitudinal recess and a body configured to be moveably coupled to the base. The base comprises a first seal positioned at a first end of the recess and a second seal positioned at an opposing second end of the recess. The body comprises a first body end and an opposing second body end. A shaft extends from the first body end to the second body end. The body is configured to move between an open position where the body is fluidly connected with the recess, and a closed position where the body engages the first seal and the second seal. The first seal and the second seal are configured to exert a force toward each other in a direction along a longitudinal axis of the body to tension the body.

Provided are a bottle lid and a water bottle. The bottle lid includes a bottle lid body, a first spout, and a second spout. An opening is disposed on the bottle lid body. The first spout passes through the opening and is disposed on the bottle lid body, where the first spout is used for a user to drink water. The second spout is embedded in the first spout, where the second spout is in clearance fit with the first spout and the second spout is used for the user to suck water. The first spout and the second spout are disposed on one opening so that the bottle lid has two manners for drinking water, that is, water can be both drunk directly and sucked.

A device and system that can perform bi-directional gas and fluid communication, thereby preventing the accidental spill and splash of sloshing liquids through the sip-hole orifice of a liquid container and/or the sip-hole orifice of its lid, but that still allows liquid to flow through the sip-hole. This is achieved by cutting into the sip-hole, extending the sip-hole and creating a tubular flow-path or labyrinth flow-path that can channel and direct the flow of liquid into a controlled and desired flow and rate via an inlet configured to do so, and by adding a removable plug. These elements help to buffer and deflect sloshing liquid thereby minimizing or preventing the accidental release of liquid, and in many cases improving the purposeful flow of liquid back into the container.
