An easily operable pull-off beverage bottle closure. The closure has a shell, a pull tab, and a liner covering the inner section of the shell providing circumferential sealing. The shell has score lines running on both sides of the pull tab enabling to tear off the closure. The liner is affixed to the inner upper section of the closing plane and covers the surface bigger than the surface limited by the score lines running through the upper plane of the shell.

Liner having an induction heat sealable layer for sealing to a rim of a container, and a pull tab for ease of removal of the liner from the container rim. An insert is disposed between multilayer upper and lower components, has a heat bondable polyolefin layer that is thermally laminated to polyolefin layers of the upper and lower components, forming a pull tab between the integrated polyolefin layers. The resulting composite resists delamination and can be formed in a single thermal lamination step, avoiding the multiple lamination steps, associated high equipment costs, and complex layer constructions of the prior art.

The Utility Model discloses a reinforced sealing barrel cover, comprising a flip barrel cover and a cover body, a clamping strip is extruded around the inner wall of the cover body, a sealing strip is set around the inner side of the cover body and above the clamping strip, and when the cover body and the barrel rim are pressed together, the sealing strip is tightly attached to the outer side of the barrel rim. The reinforced sealing barrel cover in this application can realize the sealing of the barrel cover and the barrel body under the condition of maintaining the structural advantages of the existing barrel cover and the barrel body.

An airtight container including a container body having a neck with an opening at one end, a cap having inside a portion having a convex lower end side and attaches to the neck, and a packing. A vertical cross-section of a mouth of the opening forms an upwardly convex curve. The packing has a first concave portion formed on the outer rim of the upper surface, a second concave portion formed on the lower surface sharing a bottom with the first concave portion, and a bent portion radially outboard of the center of the packing and radially inboard of the first and second concave portions are formed, to generate stress that widens the first concave portion and narrows the second concave portion when the cap is attached and the inner surface of the second concave portion is contacted against the mouth of the opening of the neck.

A condiment bottle includes a container and cap assembly. The cap assembly includes a securing part releasably connected to the container, a nozzle secured to the container by the securing part, and a closure part connected to both the securing part and the nozzle. The closure part is configured to move along a longitudinal axis of the condiment bottle from a closed position where the closure part sealingly engages the nozzle to an intermediate position where the closure part is spaced from and covering the top of the nozzle. The closure part is further configured to pivotally move from the intermediate position to an open position where the closure part is located along a sidewall of the nozzle.

A reinforced plastic container having improved rim planarity. The container has a non-round main body portion integral with a finish portion. The main body portion has a central longitudinal axis and defines a hollow interior of the container. The finish portion has an upper surface defining a rim with a circumference framing a round opening that provides access to the hollow interior of the container, a radially outwardly extending snap bead being adapted to receive and retain a closure and hermetically seal the container and including interrupted portions located around the circumference of the rim, and a plurality of reinforcements located in the interrupted portions of the snap bead and assuring substantial planarity of the upper surface of the rim even when substantial forces act on the container. Each reinforcement has a strut bounded by and centered between a pair of strut indents, with each indent supported by a buttress.
