A fastener device for closing a fluid reservoir (1) having a neck (10) with outer peripheral reinforcement (11) that co-operates with the neck to define a bottom shoulder (12). The fastener device includes a fastener ring (2) for holding a closure member (4) on the neck (10), and which includes a peripheral skirt (21) extending around the neck below the bottom shoulder (12). The skirt (21) is provided with fastener elements (26a, 26b) forming contact zones (27a, 27b) for coming into engagement with the neck (10) below the bottom shoulder (12). A blocking hoop (3) is provided that is engaged around the peripheral skirt (21) in a final mounted position. The peripheral skirt (21) forms vertical blades (22) separated by axial slots (23), the blocking hoop (3) forming vertical branches (33) that are arranged in the axial slots (23) between two vertical blades (22), in the mounted position.

A container closure (10) is provided and comprises a base (50) and a lid (55), and the footprint of the lid is larger than the footprint of the base.

The container (1) includes a body (2), a kinkable/unkinkable flexible sleeve (3) and an apertured maneuvering member (4) for maneuvering the sleeve (3). According to the invention: the body (2) and the member (4) have a globally square or rectangular shape in cross-section, giving the container (1) the appearance of a box; the member (4) is axially movable relative to the body (2), between a position in which it is freed from the wall of the body (2) and can therefore be pivoted relative to the latter, and a position in which it is engaged with the body (2); and the wall of the body (2) outwardly includes at least one part (5) made from a material having a high friction coefficient, and/or the apertured maneuvering member (4) includes, on its inner face, at least one part made from a material having a high friction coefficient.

A universal cooking/container lid for providing ventilation includes a semi-spherical base member having a circular outer-rim and an apex. The semi-spherical base member has a stand on an exterior surface and a handle on an interior surface thereof surrounding the apex. The semi-spherical base member has one or more venting perforations. A portion of the exterior surface between the stand and the outer rim may be tapered thereby providing a ventilation channel. A top portion of the handle is configured to fit snugly into a bottom portion of the stand, thereby allowing multiple cooking/container lids to be easily stacked. A method of providing ventilation while cooking is also provided.

A dispensing closure system includes an upper closure portion and a lower closure portion including an axial flow conduit and a vent conduit. The upper closure portion is axially movable relative to lower closure portion between shipping and dispensing positions. A seal is disposed on the lower closure portion over the flow and vent conduits. A peripheral spacing strip is removably secured to the upper closure portion and engages with either the lower closure or the outside of the container to prevent movement. A piercing probe includes piercing elements in alignment with the flow and vent conduits for piercing the seal. In the shipping position, the piercing elements are spaced from the seal. However, when the spacing strip is removed and the upper closure portion is axially moved to the dispensing position, the piercing elements pierce the seal to open the flow conduit and the vent conduit.

In the medical cap comprising a plug 10 made of thermoplastic elastomer and an outer frame 20 made of synthetic resin, the side surface part of the plug is contacted with an inner wall 211 of the side circuit part of the outer frame in a non-fused state and is held in a state with pressure applied from the leg part of the outer frame 22. As a result, the wetted surface of the plug is not flat shaped but has an inclination downward to the circle center. Protrusion 14 can also be provided on the wetted surface and in such a case, the bottom part of the protrusion part that is one part of the wetted surface has an inclination downward to the circle center.

A sealing device for a container comprising a circular cap designed to seal the neck of the container and a cover made from a synthetic material capable of covering both the neck and the cap fitted on the neck, the cover being provided with means for locking onto the neck, the cover being in one piece and comprising a skirt capable of radially surrounding a collar of the neck of the container, and an annular portion provided with a central opening allowing permanent access to the cap, and the skirt having at least two jamming areas for jamming the cap and, on the inner radial face thereof between the two jamming areas, a release area with a diameter strictly greater than the minimum unstressed diameter of the cap.
