Closing system for bottles and small bottles and method for the use thereof for the opening of said bottles integrated by a single piece with three differentiated parts, two of them, inner threaded hole and screw (7), made of rigid material and joined by a pre-cut line, used as a base on which an elastic part (10) is overpressed. This elastic part (10) has some perimeter grooves (18) that, when fastening the screw (11) in the inner threaded hole (4) of the neck (3), presses the elastic part (10) and secures it against the walls of the bottleneck (3). The bottle can be opened by just lifting the covering half fins (9) and turning them in the opposite direction to the thread, so the elastic part (10) is decompressed and can be easily removed, leaving the bottle opened. All materials are food grade materials.

A bottle closure includes a closure element and a cap element. The closure element is configured to be received at least in part within a portion of a bottle. The closure element includes a first portion of a first material and a second portion of a second material. The second material has a lower durometer hardness than the first material. The second material is moldably bonded to the first material. The closure element defines a hollow interior. The cap element is coupled to the closure element.

A stopper for a container has a jacket portion insertable into the container, wherein the jacket portion has a through-opening formed in an axial direction, wherein the stopper has at least two segments, wherein the respective segment has a free end, wherein a first portion of the free end of the respective segment forms a subregion of the jacket portion, and a second portion of the free end of the respective segment protrudes radially inward in relation to the jacket portion, wherein a third portion of the free end of the respective segment protrudes radially outward in relation to the jacket portion, wherein the second portions form a cover portion that can be pierced through in the axial direction and that closes the through-opening, wherein the third portions form a bearing portion of the stopper for bearing against a container edge of the container.

A stopper for a container with a lid with a peripheral wall engaging around the neck of the container and with an olive seal provided with an outer, peripheral annular bead for jamming engagement in the container opening includes an inner surface of the olive seal having a ribbed wall surface, which is defined by a plurality of grooves and webs extending in the longitudinal direction on the wall of the olive seal.

The stopper is equipped with a stopper main body having a guiding path extending in an axial direction. A stopper member has a flow path extending in the axial direction and is inserted in the guiding path of the stopper main body. A sealing member inserts into the flow path of the stopper member in such a manner as to block the flow path. The stopper member is equipped with, at a position where the sealing member is inserted, a first peripheral wall section fixed in a manner as to extend in the axial direction and a second peripheral wall section separated from the first peripheral wall section in a circumferential direction and extending radially outward along the axial direction.

A bottle stopper includes: a cylindrical guide having multiple slits that run parallel to a center axis along a portion of the guide; a cylindrical nut that is able to move along the center axis, the nut including multiple ridges, each ridge engaging a particular slit such that the nut is not able to rotate relative to the guide about the center axis; a knob coupled to a threaded bolt; and a set screw that secures the knob relative to the guide such that the guide and the knob move together as a rigid body along the center axis, where the threaded bolt is able to engage the nut such that the nut is moved along the center axis when the knob is rotated about the center axis. A method of sealing a container includes: inserting a plug and stopper; and rotating a knob to reach a specified sealing pressure.
