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.

A temperature-protective package includes a rigid container configured to receive a temperature-sensitive product. A flexible liner is attached to the rigid container such that a pocket is formed between the rigid container and the flexible liner. Phase change material (PCM) is situated in the pocket. The PCM conforms to a contoured surface of the rigid container. In an alternative implementation, a temperature-sensitive package includes a pocket of PCM within a flexible liner. The flexible liner defines a preferred shape of the temperature-protective package. The flexible liner also defines an opening for receiving a product. The opening corresponds to the preferred shape. In one implementation, multiple flexible liners can be utilized to define the preferred shape and the opening.

A container for storing perishable contents comprising an inner storage chamber defining top and bottom ends and comprising a floor at the bottom end thereof and an inner wall extending from the floor towards an opening at the top end thereof. The floor and the inner wall defining a storage cavity therebetween. An outer wall covers the inner wall and downwardly extends from a junction therewith at or near the top end of the storage chamber towards a bottom edge thereof at or near the bottom end of the storage chamber. The outer wall and the inner wall are spaced apart to define an air channel therebetween for receiving air. The bottom edge of the outer wall and the floor of the storage chamber define an opening therebetween leading to the air channel. The air channel provides for allowing a layer of air between the outer wall and inner wall to act as insulation for the perishable contents.

A heat insulating container is described which can keep a heat insulating state (including cold insulating state) of an inside container stored in an outside container for a long period of time, and improve safety and usability. The heat insulating container may include the outside container having a heat insulating structure; the inside container having a cold insulating structure or a heat insulating structure; and a cover member which is attached to the inside container in a state in which the inside container is stored in the cover member; in which the inside container is stored in the outside container in a non-contact state through the cover member.

A bottle having a reclosable and resealable lid is disclosed. The bottle can have a removable pedestal base. The base can elevate the remainder of the bottle off of the surface upon which the bottle is resting. The lid can have a seal for a drinking mouthpiece outlet and a pressure equalization port. The lid can have a concave indentation or seat aligned with a hinge connecting a top of the lid to a base or rim of the lid. When opened, the seat can rest against the lid rim, opening the lid to more than a 180° lid opening angle.

A heat exchanging thermal liquid container system that comprises a main body at least partially defining a liquid reservoir structured and operable to retain a liquid, and a phase change material (PCM) liner comprising a PCM liner PCM having a selected melting temperature, and/or at least one PCM pod. Each of the at least one PCM pod(s) comprising a respective PCM pod PCM having a respective selected melting temperature. Wherein the PCM liner and/or the at least one PCM pod are disposable within the liquid reservoir such that when a liquid is disposed within the liquid reservoir the liquid will contact at least one of the PCM liner and the at least one PCM pod such that thermal energy can be exchanged between the liquid and the respective at least one of the PCM liner PCM and the at least one PCM pod PCM.

A temperature regulating device for a beverage comprises an upper cover, a first barrel and a second barrel connected below the upper cover, wherein the upper cover is provided with an inlet and an outlet for a beverage to flow in and out; the second barrel is located in the first barrel; a cavity for receiving the beverage is formed between the first barrel and the second barrel; the inlet and the outlet are communicated with the cavity; a first chamber for storing media is formed in the second barrel; the upper cover is recessed inward in the middle to form an inner concave part; the inner concave part is funnel-shaped, the bottom of the funnel bulges upward to form a conical convex part, and there are a plurality of inlets machined on the wall surface of the inner concave part, and the second barrel is connected below the convex part; the beverage is directly inverted at the position of the concave part, and enters the interior of the cavity from the inlet, so that the pouring of the beverage becomes convenient, and basically no splash occurs; the design of the convex part plays a certain drainage role, further avoiding the splash and quickly adjusting the temperature.

A heat exchanging thermal liquid container system that comprises a main body at least partially defining a liquid reservoir structured and operable to retain a liquid, and a phase change material (PCM) liner comprising a PCM liner PCM having a selected melting temperature, and/or at least one PCM pod. Each of the at least one PCM pod(s) comprising a respective PCM pod PCM having a respective selected melting temperature. Wherein the PCM liner and/or the at least one PCM pod are disposable within the liquid reservoir such that when a liquid is disposed within the liquid reservoir the liquid will contact at least one of the PCM liner and the at least one PCM pod such that thermal energy can be exchanged between the liquid and the respective at least one of the PCM liner PCM and the at least one PCM pod PCM.

A water bottle capable of freely adjusting temperature and a method for vacuumizing a sealed space thereof. The vacuumizing method includes: injecting a low-boiling point liquid into a sealed space between an inner container and an outer shell through a liquid injection hole; after the liquid injection is completed, placing a bottle mouth portion of a water bottle upside down, so that the low-boiling point liquid flows to the bottle mouth portion; heating the water bottle to vaporize the low-boiling point liquid, where since the specific gravity of the gas generated after vaporization is greater than the specific gravity of air, the air in the sealed space is lifted upward and discharged from the sealed space through the liquid injection hole; and after heating for a period of time, closing the liquid injection hole to form a vacuum or semi-vacuum state in the sealed space. The traditional vacuumizing method cannot perform vacuumizing after the conventional hand warming bottle or icing bottle is filled with a heat-conducting liquid. According to the present invention, the principle that the vaporization temperature of the low-boiling point liquid is low and the gas generated after vaporization is heavier than air is cleverly utilized for performing vacuumizing, thereby resolving the problem that the traditional vacuumizing process cannot perform vacuumizing after the sealed space is filled with the liquid.
