A liquid-containing container is the liquid-containing container containing a liquid and includes a container body with an opening portion and a stopper that closes the opening portion and has oxygen permeability. The stopper includes a stopper body portion and a barrier layer provided on at least part of a surface of the stopper body portion. The barrier layer constitutes at least a surface of a portion of the stopper to be inserted into the container body and a surface of the stopper defining a storage space for the liquid and includes at least one selected from the group consisting of a p-xylylene layer, a diamond-like carbon layer, and a fluoropolymer layer.

There is a closure 1, which is, in this case, shown as closing a mouth 2 of a bottle 3, wherein the bottle is made of glass and has an external outwardly extending integral collar 4 which extends fully around an outside of the neck of the bottle and is of a constant shape and size at any location around the periphery. The seal 5 is held under compression against an uppermost rim 6 of the bottle mouth 2 and surface 7, which is adapted to engage with compression force the seal 5. Upon extraction of portion 8 from within the mouth of the bottle, a popping sound is achieved by having the position of the seal somewhat below the mouth prior to extraction so that there will be upon extraction an evacuation of the headspace within the bottle.

A storage vessel is provided comprising a vessel body, a vessel plug, and at least one commemorative element. The vessel body has a bottom securely joined to a domed top to define an interior chamber accessible through an opening defined on the bottom. The vessel plug secures the opening and may be obscured during use to disguise the opening. The at least one commemorative element comprises a rod with a star mounted on its distal end, extending off the domed top. The vessel may further comprise an ornamental structure extending off the domed top and an identifier. The vessel may be used as an urn, and the interior chamber may be used to accommodate the remains of loved ones, including small and large pets.
