A stopper for use with a container containing liquids, solids, or gases. The stopper includes a main body. The main body includes an upper portion. The upper portion has a diameter greater than a diameter of an opening of the container. The stopper also includes a flexible sheath affixed to the stopper. The sheath can be rolled down an exterior surface of the container to facilitate a seal of the container. In addition, the main body includes an annular groove sized and shaped to retain the sheath when rolled up. In one embodiment the present invention may include a lower portion having a plug sized and shaped to fit within the opening of the container to prevent liquids, solids, or gases contained in the container from exiting the opening.

The present disclosure relates to the field of bottle stopper devices, and in particular, to a quick opening and closing container stopper, which includes a fixed shell and a movable stopper body. The fixed shell is provided with a dodging opening. The movable stopper body is provided with a limiting plate. An elastic sealing sleeve abuts against and between the limiting plate and the fixed shell. A knob is rotatably connected to the movable stopper body. The knob includes a side lug. When the container stopper is in a locked state, the side lug extends beyond a contour range of the dodging opening, and the fixed shell and the limiting plate are close to each other and drive the elastic sealing sleeve to bulge outward. When the container stopper is in an unlocked state, the side lug is accommodated in the dodging opening.

A container assembly is configured to maintain a predetermined moisture in a container for storing a product, where the container assembly includes a container with an upper container opening and a closed base, a stopper with a central hole passing through the stopper and a chamber formed by a peripheral wall, an upper wall with a central hole and a lower perforated base wall, where the chamber is connected to the stopper and a substance is arranged in the chamber, and where an inflow of ambient air moves through the central holes of the stopper and the chamber and causes the substance to give off water, wherein the water passes through the lower perforated base wall of the chamber.

A bottle cap may include a threaded mounting section configured to be screwed to an outlet port of the squeeze bottle from a first end of the threaded mounting section, a spring-loaded nozzle attached to a second opposing end of the threaded mounting section, where the spring-loaded nozzle includes a nozzle and a first resilient spiral spring connecting the second end of the threaded mounting section to an outer surface of the nozzle. The bottle cap may further include a first spring-loaded plug mounted within the threaded mounting section between the opening of the squeeze bottle and the inlet port of the nozzle. The first spring-loaded plug may include a first plug attached to an inner surface of the threaded mounting section utilizing a second resilient spiral spring. The first plug is configured to sit on a peripheral ledge of the inlet port of the nozzle.

A bottle stopper adapted for self-opening and self-plugging a bottle, comprising a cylindrical cover having a bottom end and a top end. The cylindrical cover is sized and shaped to plug a bottle. A cartridge is encompassed by the cylindrical cover and has a fluid chamber; the cartridge also has at least one lateral protrusion thereon to form between the cartridge and the cylindrical cover. There is at least one fluid channel for fluidly connecting between a space below the bottom end and above the top end. A conduit having at least one inlet and at least one outlet is for fluidly connecting transferring the fluid of the fluid chamber to outside of the bottle stopper. An activation cap is mounted to push the conduit along a longitudinal axis of the cylindrical cover from a closed state to an open state.

A packaging container includes a lid assembly, an applicator, an outer stopper, an inner stopper, and a bottle, where the applicator includes a mounting portion, a connecting portion, and an application portion; two ends of the connecting portion are respectively fixedly connected to the mounting portion and the application portion; the mounting portion is fixedly connected to the lid assembly; the lid assembly covers a bottle mouth of the bottle; the outer stopper is fixedly provided at the bottle mouth of the bottle; the inner stopper is rotatably provided in the outer stopper; a first scraping hole and a second scraping hole communicating with each other are formed in the inner stopper; the first scraping hole is configured to scrape materials on the connecting portion; the second scraping hole is configured to scrape materials on the application portion; and the application portion can drive the inner stopper to rotate.

A beverage sealing cap that absorbs oxygen keeps a bottled beverage, such as a bottle of wine, fresh after opening and re-sealing. The beverage sealing cap is made with a thermoplastic elastomer stopper containing an oxygen absorber. When inserted into an opened beverage bottle, the stopper seals the bottle to prevent ingress of air, while the oxygen absorber removes the oxygen present in the air inside the bottle. As a result, the contents of the bottle are preserved in a fresh state, avoiding degradation of flavor and waste due to spoilage.

A tube seal cap assembly for use with a product tube having a top wall and a nozzle comprises a primary cap and a gripper ring. The primary cap includes a top end and a bottom end. The gripper ring is operatively connected to the primary cap proximate the bottom end, and the gripper ring and the primary cap include mating features configured and arranged to prevent rotation of the gripper ring relative to the primary cap. The gripper ring includes at least one inwardly extending protrusion. In use, when the tube seal cap assembly is operatively connected to the product tube, the primary cap is configured and arranged to receive the nozzle and the at least one inwardly extending protrusion is configured and arranged to carve into the nozzle.

A container tamper detection capsule comprising a top cover member, a lid member an NFC tag adhesive, a drive member and a ring member wherein the drive member is configured to move within the ring member between i) a first closed position, on which the secondary component is glued to the ring member, and ii) a second opened position, on which the secondary component is separated from the main component of the NFC tag adhesive, and the drive member is immobilized, both axially and longitudinally, in the ring member, being at the lower part of the latter member a stopper member inserted and immobilized. The invention further relates to a process of operating the container tamper detection capsule and to a container tamper detection process.

A sealed pharmaceutical container comprises a flange comprising an underside surface, an outer surface extending from the underside surface, the outer surface defining an outer radius r.sub.o of the flange; and an upper surface extending between the outer surface and an inner surface defining an opening in the sealed pharmaceutical container. The upper surface comprises a sealing region extending between the opening and the outer surface and comprising a radius r.sub.sr that is less than r.sub.o. The sealed pharmaceutical container also comprises a sealing assembly comprising sealing portion in contact with the upper surface at a lower surface of the sealing portion and a cap compressing the stopper against the upper surface. After compression, the sealing portion of the stopper comprises a compressed radius r.sub.sc that is less than r.sub.sr adjacent the upper surface.
