An apparatus and methods are provided for an insulated beverage bottle to maintain the temperature of liquid contents and exhibit reduced sound upon being dropped onto a hard surface such as a tennis court. The insulated bottle includes a bottom cushion and a top cushion that are coupled to an outer cylinder. The outer cylinder and the top and bottom cushions exhibit impact resistance and noise suppression properties. A double-walled container is disposed inside the outer cylinder. An insulative material is disposed between the doubled-walled container and the outer cylinder. The insulative comprises fumed silica vacuum insulation that surrounds a majority of the exterior of the double-walled cylinder. A top lid is threadably joined with the insulated bottle such that liquid contents may be stored in an interior of the bottle. A straw holder provides access to a straw and prevents liquid contents from leaking out of the bottle.

A lid for an insulated container comprises a flexible gasket configured to facilitate a seal between the lid and an inner wall of the insulated container, and further configured to expand into an interior compartment of the insulated container responsive to a vacuum developing in the interior compartment. A diaphragm chamber is situated opposite the flexible gasket from the interior compartment when the lid is fully engaged with the insulated container. One or more air channels couple the diaphragm chamber to an exterior of the lid. The development of a vacuum in the interior compartment of the insulated container draws a force on the flexible gasket, thereby reducing pressure in the diaphragm chamber. The negative pressure in diaphragm chamber is back-filled with external air, which enters the lid via the air channels. The lid may then be removed without excessive vacuum forces.

A container assembly and a container lid are provided. The container assembly includes a container body, a lid, a sleeved portion, an annular pressing portion, and a straw. The container body has an opening portion at an upper end thereof. The lid is detachably disposed on the opening portion and has a top portion at a top end thereof. The annular pressing portion is formed at a side surface of the sleeved portion. The sleeved portion has a second accommodating space recessed therein. When the lid is disposed on the opening portion, the annular pressing portion is in contact with an upper end edge of the opening portion, and a height of a bottom surface of the top portion is greater than a height of the upper end edge of the opening portion. The straw is accommodated in an accommodating space of the container body.

A dual-chamber beverage container for reducing a temperature of a hot beverage to a safe and comfortable drinking temperature. The dual-chamber beverage container includes an insulated bottom chamber for maintaining a temperature of a hot liquid, a cooling chamber for receiving and cooling the hot liquid to a comfortable drinking temperature, and a housing. The housing contains a motorized pump operably connected to a power source also contained within the housing. A transport tube extends from the bottom chamber, through a channel within the housing and terminates within the cooling chamber. A switch is disposed on an exterior side of the beverage container and operably connected to the motorized pump such that activation of the switch causes the motorized pump to pump air into the bottom chamber, displacing the liquid and forcing the liquid from the bottom chamber into the cooling chamber through the transport tube.

Provided is a thermostatic container that improves both the communication radio wave transmissivity and keeping cold performance of a thermostatic container. A thermostatic container includes: a vacuum heat insulating container; a vacuum heat insulating lid configured to close the vacuum heat insulating container; a box body housed inside the vacuum heat insulating container; a box lid configured to close the box body; and a phase change material provided on a bottom portion and a wall portion of the box body and the box lid. An area made of a radio wave transmissive organic substance is provided on a path leading from inside of the box body to outside of the heat insulating container.

A liquid container system includes an inner bottle that has a base portion with a first diameter. The system also includes an outer bottle that surrounds at least a portion of the inner bottle. The outer bottle includes a mid-portion that has a second diameter, and the second diameter is less than the first diameter. The system further includes a first indent in the inner bottle that, responsive to an applied pressure, decreases the first diameter of the base portion of the inner bottle such that the first diameter is less than or equal to the second diameter.

A stopper for a food jar is described that may be used to store and transport food items. The stopper includes a bottom wall and a sidewall. The stopper includes one or more vent passages connecting the bottom wall and the sidewall to provide pressure relief. A vent gasket is provided at the bottom wall that opens when pressure inside of the container is elevated to allow air to pass into the vent passages and vent outside of the container.

Silicone-containing cartridges having a plunger at one end thereof are effectively sealed against moisture penetration by introducing a silicone oil composition having a viscosity of from 5000 mPa.Math.s to 100,000 mPa.Math.s between the walls of the plunger and the interior surface of the cartridge wall.

Disclosed embodiments relate to a removable insert structure, which may be formed of glass and configured to be disposed within an outer vessel. The insert structure may have a sipping portion configured to extend out of the open end of the outer vessel. In some embodiments, the cross-sectional width of the sipping portion may vary, for example from the shoulder end to the sipping end. For example, the cross-sectional width of the sipping portion may be wedge-shaped, with the width at the sipping end being less than the width at the shoulder end. Insulated containers including removable insert vessels and lids for use with insulated containers are also disclosed.
