Abstract: Provided are a cap capable of being easily and reliably opened and unsealed not limited in design even if an inner cap with a small diameter is used for the cap, producing no refuse after the unsealing, and not unnecessarily large in size, and a container with the cap. When an over cap (3) is rotated in the opening direction, a pair of screw threads (10a, 10b) as opening means are advanced in the direction in which they are tightened together, and this cuts off a planned opening section (4) from the inner cap (2). Thus, the cap has a relatively simple structure and can be simply and reliably unsealed by small force. Also, the planned opening section (4) is integrated with the over cap (3) after unsealing the inner cap (2), so that no refuse is produced after the unsealing, eliminating the need to clear it away from a table.

Abstract: An integral seal opening means within a sport closure cap for containers, in which a tamper evident seal with a reinforced rim secures the mouth opening. The closure cap holds a minimum of three protrusions, extending towards the seal, each having cutting edges of which the lower one is at a smaller radius. These protrusions engage with the tamper evident seal, when the cap is rotated clockwise, thereby cutting off part of of the seal rim and at the same time cutting three banana shape slots in the seal. For single serve beverage bottles with tamper evident seal and a sport closure, there is no need to unscrew the cap for opening the seal and getting access to the beverage. Initially the reinforced rim is used to prevent protrusions from accidently opening the bottle seal. The opened seal remains in place while the sport closure is held onto the bottle.

Abstract: The invention relates to a closure system for containers comprising a threaded plug (1) and the neck (3) of the container (2) or the similar embodied in the form of an pouring aperture (5), the threaded plug being screwed on the neck in such a way that said pouring aperture is closed. The inventive closure system for containers is characterised in that it is embodied in the form a single-use closure system which comprises an extensible flange (15) arranged at the level of the threaded plug in the back clamping area of the flange (7) of the neck (3) embodied for this purpose. The external radial size of said extensible flange is greater than the radial dimension of a hole defining the back clamping area of the flange. The extensible flange can, for example be engaged in the pouring aperture (5) of the neck (3), and the back clamping zone (7) can be provided in a pouring passage (4) in a neck part.

Abstract: An internally threaded plastic closure in accordance with the present invention includes an array of axially extending, circumferentially spaced internal ribs which intersect the internal thread formation of the closure. By this arrangement, vent passages are defined between adjacent ones of the internal ribs, thus providing the closure with desirable gas venting characteristics, while avoiding the provision of vent grooves extending into the inside surface of the closure side wall, which can undesirably impair the strength of the side wall. By the present construction, the amount of polymeric material from which the closure is formed can be desirably reduced, while maintaining the desired dimensional characteristics of the closure, to facilitate use with existing containers and high-speed capping equipment.
