A lid for a container, such as a beverage cup, is provided. The lid includes a top wall for covering an opening of the container. The top wall may include an inner layer and an outer layer. The inner layer may include a first perforation line defining an openable sip hole area. The outer layer may be connected to the inner layer at the openable sip hole area. The outer layer may include a tearing off area that may be torn off and result in the opening of the first perforation line to create a sip hole in the inner layer.

A leak resistant lid assembly for a beverage container where the lid assembly has a straw or similar means for a user to drink liquid is disclosed. The lid assembly may include a base, a straw that extends through the base, a gasket, and a grommet. The base may have a primary opening that receives the straw and a secondary opening in the top of the base, where the secondary opening acts as a vent to prevent a vacuum from occurring when drinking from a straw. The grommet may have a spiral ring may help create a flow path for air from inside the beverage container to the exterior environment.

An expandable bowl has an open top and a plurality of configuration changing side members connecting the open top to a base member. The configuration changing side members are designed to allow a user to pull the base member to changing the side members from a collapsed configuration to an expanded configuration, thereby increasing the overall volume of the bowl. The expandable bowl may be useful for various products, such as pre-packaged salads, where the salads may be packaged and displayed in the collapsed configuration, thereby minimizing shelf space, and may be changed to the expanded configuration by a user to permit tossing of the salad without risking spillage of the contents of the bowl.

A beverage container for hot or cold beverages, where the lid and base are connected via a glass joint. The glass joint forms a seal between the lid and base and eliminates the need for a synthetic material to form such a seal. The base has a double wall construction forming a cavity between the two walls. One or more of the surfaces facing the cavity are coated with a thermally reflective coating, which along with the glass materials, reduces heat transfer to the external surroundings. The lid is formed by a glass shell with an internal cavity, where the internal surfaces defining the cavity are optionally coated with a thermally reflective coating to further insulate the beverage container. A vent hole may be formed in a bottom of a dual-walled beverage container to prevent the formation of a vacuum. The outer surface of an inner wall of a dual-walled beverage container may have an inductively couplable layer secured to the inner wall to permit heating of fluids.

Disclosed is a chemical container capable of discharging gas generated from a chemical by stably securing a discharge passage of the gas even when the posture or tilt of the chemical container is variously changed, i.e. when the chemical container is turned over or falls sideways, whereby it is possible to prevent an excessive increase in internal pressure of the chemical container due to generation of the gas. The chemical container includes a container body having a storage compartment configured to store a chemical, an exhaust port disposed at one side of the container body, the exhaust port being configured to connect the storage compartment and the outside of the container body to each other in such a manner that fluid movement therebetween is possible, an exhaust tube disposed in the storage compartment so as to be connected to the exhaust port in such a manner that fluid movement therebetween is possible, and an exhaust buoyancy unit. The exhaust buoyancy unit has a buoyancy body disposed in the storage compartment in the state of being connected to the exhaust tube so as to float on the chemical stored in the storage compartment, an exhaust channel provided inside the buoyancy body, the exhaust channel being configured to connect the storage compartment and the exhaust tube to each other in such a manner that fluid movement therebetween is possible, and a filter membrane coupled to the buoyancy body, the filter membrane being configured to transmit gas through the exhaust channel and to block the chemical, thereby preventing the chemical from passing therethrough.

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.

A container arrangement is provided and is configured to maintain a predetermined amount of moisture in the container for storing a product, where the container arrangement includes a container with an upper container opening and a closed base, a stopper with a central hole for fastening the stopper to the container opening, a hollow chamber with a peripheral wall, an upper wall with a central hole and a lower perforated base wall, where the chamber is put together with the stopper so that the central holes are in alignment with one another and a substance is arranged in the chamber, where the substance is a consequence of the inflow of ambient air through the central holes, and gives off water, which passes through the perforated base wall.

A container lid and base assembly includes lid and base stacking features, as well as base chamfers that align with vents provided in the lid. When a plurality of the container assemblies is stacked, the lid and base stacking features nest with each other, while the chamfers align with corresponding vents in the stacked assemblies so that none of the vents is blocked by a next-higher container assembly. The stacking features can be centrally located, and the vents can be peripherally located. A plurality of the container assemblies can have differing sizes and/or shapes, while including mutually compatible stacking features, thereby enabling container assemblies of differing sizes to be stacked without blocking any of the vents thereof. The vents can be holes or “C” vents. The lid and/or base can be manufacturable by thermoforming. The lid and base can be separate, or joined by a hinge.

An insulating container having a base and a lid is provided. In some examples, the insulating container further includes a pressure regulation device. In other examples, the insulating container may include latching devices comprising an elastomeric latch upper and a semi-rigid latch lower configured to engage an insulating container keeper when the lid is in a closed and a secured position. In still other examples, the latch upper and the latch lower are configured in a recessed position, and flush with a front side of the insulating container lid and flush with a front side of a bottom portion of the insulating container when the latches secure the lid in a closed position.

In a separation instrument configured to separate a gaseous substance from a solution contained in a container, the separation instrument includes: a first end; a second end; and a side surface provided between the first end and the second end, wherein a plurality of gas introduction grooves configured to swirl a gas and introduce the gas into the container are formed on the side surface between the first end and the second end, and a discharge hole configured to discharge the gaseous substance separated from the solution together with the gas is formed between a center portion of the second end and a center portion of the first end.
