A hinged flip-top cap with a tamper-evident inner ring includes a base portion, which extends into a pourer portion, and a flip-top lid. A hinge arrangement connects the flip-top lid to the base portion and is foldable with respect to said base portion, so that flip-top lid can be tilted with respect to the base portion and moved between a closed position above the base portion and an open position detached and rotated from the base portion. The inner ring is position inwardly of the flip-top lid and the base portion and operates as a tamper-evident element that reveals whether a first opening between the flip-top lid and the base portion has been made.

A sealing system for container comprising material and a method using the system The present invention provides a sealing system for sealing a container comprising material, wherein the system comprises at least a first part which is a cap for sealing a container comprising a seal; and a second part which is a coupling member that is mounted to a dispenser unit, wherein the coupling of both parts with each other is configured that they can be twisted against each other while preventing axial movement of first and second part.

A package closure (10) comprising a neck (12), a cap (11) for closing an opening of the neck (12), and a folded portion (21) connecting the neck (12) and the cap (11), wherein the neck (12) has an axis (A) and is formed with a tubular portion (16) and an inward projecting sealing flange (18), wherein the cap (12) is formed with a top portion (13) for covering the opening of the neck, and an axially extending sealing ring (19) to interact with the sealing flange (18) to form a seal between them. The neck (12), the cap (11) and the folded portion (21) are formed in a single integrated piece. The cap (11) is further formed with an axially extending wall (14) arranged radially outside of the tubular portion (16) of the neck (12), wherein the folded portion (21) connects the wall (14) of the cap (11) with the neck (12). The top portion (13) of the cap (11) is connected to the wall (14) through a breakable notch (23) and a hinge (24), wherein the top portion (13) is openable by tearing along the notch (23) and folding along the hinge (24). Disclosed is also a method for producing the package closure (10).

In some embodiments, apparatuses and methods are provided herein useful to dispensers. In some embodiments, a dispenser comprises a main body assembly including an outer wall and an inner wall, the inner wall defining an aperture through the main body, a seal, wherein the seal is affixed to the main body and encloses a lower portion of the aperture, a button seated within the aperture and configured to be manipulable between a first position and a second position, and a container housed within the button and configured to store a material, wherein when the button is in the second position the container contacts the seal to allow the material to exit the dispenser.

A reusable pour spout system that may be attached to different container types to dispense different substances, including course and fine granular materials and liquids. A port component has a proximal tubular end and a flange that is larger than the tubular end. The flange further includes a hole-cutting structure adapted to pierce the wall of a container, with a cutting edge adapted to form a hole in the container when the port component is rotated by a user after piercing. This positions the flange within the container with the tubular end exposed to receive a nut that traps the wall of the container between the nut and the flange. A cap is provided to seal off the port. The tubular end of the port component, the nut, and the cap may all be threaded. Different structures to enhance cutting and sealing are disclosed along with preferred method steps.

A plastic cap, which is a highly producible one-piece type cap when molded, but becomes a two-piece type cap excellent in sealability and openability when used, and enables a small-diameter pouring opening to be formed, is provided. The plastic cap comprises: a cap body which is composed of a top plate section and a skirt section, has a pouring nozzle formed on an outer surface of the top plate section so as to surround an opening-scheduled portion, and is fitted and fixed to a container mouth; and a top lid composed of a top face, and a circumferential wall suspending from an outer peripheral edge of the top face. The top lid has, formed therein, a protrusion protruding downward from an inner surface of the top face and having an engaging portion on an outer surface thereof. The cap body has an inner plug formed therein. The inner plug is composed of an annular sidewall having an outer diameter enabling the annular sidewall to intimately contact an inner surface of the pouring nozzle; and a bottom formed at a lower part of the annular sidewall. The inner plug is formed integrally with the cap body via a breakable weakened portion at a position below a seal portion of the pouring nozzle having an inner diameter enabling the seal portion to intimately contact the inner plug. On an inner surface of the annular sidewall, an engaged portion vertically engageable with the engaging portion of the protrusion is formed.
