A container closure includes an outer cap, an inner cap, and a seal. The outer cap includes a top wall and an outer sidewall extending downward from the top wall. The inner cap is secured within the outer cap and includes a bottom wall and an inner sidewall extending upwardly from the bottom wall. The seal is secured to the inner cap and includes a seal sidewall and a rim extending inwardly from the seal sidewall. The seal sidewall sealingly engages the inner sidewall and the rim sealingly overlaps the bottom wall. The inner cap together with the seal define an air pathway in fluid communication between a space between the outer and inner caps and an air opening formed on the bottom wall of the inner cap and selectively covered by the rim.

A packaged assembly of a hermetically sealed container and cigarette, and method of forming the assembly. The container is hermetically sealed for airtight conditions for freshness, whereby an interior space is either filled with an inert gas or is evacuated down to a pressure close to 0 atm to remove substantially all air (oxygen) from within. The container may be clear glass to afford good visibility of the cigarette within an interior space thereof. However, a relatively large label may be affixed to the exterior of the container to occlude most of the light from reaching the cigarette.

The present application discloses a container, having a housing with a housing bottom wall and a housing sidewall, and a liner having a liner bottom wall and a liner sidewall. The liner is detachably connected to the housing sidewall, so that the liner is received in the housing chamber. At least a portion between the housing sidewall and the liner sidewall has a gap therebetween. This application discloses a double-layer container having a liner and a housing detachable with each other, so that the housing can use a combination of different shapes of the liner. At the same time, the liner of the container in the present application is made of a flexible material to facilitate cleaning of the liner. On the other hand, the double-layer container of the present application can directly use the liner as a seal, which is convenient for cleaning.

An easily openable container lid includes a shell and liner. The shell includes a flat circular top wall, a skirt wall having an arcuate part extending arcuately radially outward and downward from the peripheral edge of the top wall in a longitudinal cross sectional view and a linear part extending vertically downward following the arcuate part, and a grip piece extending from the lower end of the skirt wall. The top wall, the skirt wall and at least a base part of the grip piece are integrally formed of a metal sheet, and a pair of scores each composed of first and second portions are formed on the shell. The first portions extend on the skirt wall upward from both sides of the grip piece, and the second portions extend arcuately between the upper end part of the skirt part and the peripheral edge part of the top wall.

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.

Various enhancements of heat seals are provided herein with sealant layers that provide for decreased chance of oversealing the heat seal to a container. Such enhancements include the use of various types of resins in combination to provide for desirable heating and sealing characteristics. Further, the heat seals may be especially suitable for use with polyester containers, such as those containing polyethylene terephthalate.

The Improved Salad Dressing Preparation and Storage Container is a food preparation device that allows for conveniently measuring, mixing, and dispensing of homemade vinaigrette salad dressing. The device uses two adjacent, adjoined compartments that are volumetrically proportioned to allow for the recommended ratio of oil and vinegar (acid) to be consistently achieved by filling them with oil and vinegar to the same apparent level. The Improved Salad Dressing Preparation and Storage Container may also be configured for commercial sale pre-filled with the oil and vinegar contents, those kept separated by sealing the adjoined compartments using an adapted seal. The pre-filled container may be designed and marketed for secondary use by consumers for use in making their own vinaigrette salad dressing recipes.
