摘要:
A pre-assembled container closure assembly (1) has a plastic spout body (2) with a tubular neck (4) delimiting a product passage (6) that extends to a mouth opening (8) of the neck. A rotational cap (30) is secured in closed position on the neck. The cap has a cap body including a top wall (31) and a skirt (32). The cap body further includes an annular inner sealing ring (40) depending from the top wall. The inside of the neck is provided with an inward tapering annular guide surface (15) that is contacted by the inner sealing ring when the cap is secured onto the spout body and then causes an elastic deformation of the inner sealing ring and/or the neck. The inner sealing ring is embodied such that the first annular sealing surface (41) on the exterior side of the inner sealing ring and a lowermost annular surface (43) of the interior side of the sealing ring adjoin one another directly at an apex (44) which forms the lower edge of the inner sealing ring, and in that—with the cap in closed position—said apex lies against the interior side of the neck, said lowermost annular surface extending from said apex to form an angle of at least 90° with an exposed surface portion of the interior side of the neck directly below said apex so as to avoid the presence of any gap between the inner sealing ring and the neck at said apex.

The disclosure includes a cap having a first portion made of a plastic material and forming a bottom for covering a container neck and a protective side wall for surrounding the container neck, and a second portion made of a flexible material that is compatible with the plastic material of the first portion and separate from the plastic material of the first portion, the second portion being annular and consisting of a flexible seal, which projects from the bottom toward the interior of the side wall and which is welded to the first portion. Thus, the manufacture of the stopper by molding includes injecting a flexible material to produce the flexible annular seal and then the movable portions of the mold are placed such that the flexible material is in a groove that is set back from the planar surface of the mold.

A tamper-indicating plastic closure, and tamper-evident package includes a closure wherein the closure includes a pilfer band having a substantially continuous tamper-ring. The tamper-ring extends generally angularly upwardly and inwardly of the closure in a tamper-indicating orientation of the tamper-ring for engagement with a relatively enlarged annular locking ring of the associated container. The tamper-ring includes a plurality of circumferentially spaced projections, which comprise relatively thick regions or shoulders, which act to limit lateral movement of the pilfer band with respect to the container by engagement of at least one shoulder with the associated container generally beneath the container locking ring.

[Problems to be Solved] In a synthetic resin container closure of a type which includes a body and a tamper evident bottom portion connected to the body via a plurality of breakable bridge portions arranged with spacing in a circumferential direction, and in which the body continues to be connected via unbroken connecting pieces to the tamper evident bottom portion continuously mounted on a mouth-and-neck portion of a container even after the bridge portions are broken to remove the body from the mouth-and-neck portion of the container, an improvement is made so that the container closure can be applied, without posing problems, even when the ascent distance of the body when removed is relatively long.[Means to Solve the Problems] Each of the unbroken connecting pieces is in such a form as to include two tilting portions whose tilting directions are opposite to each other.

A safety bottle cap for preventing damage from anti-burglary tearing flanges has an opening, a cover and a two-layer tear ring between the opening and the aperture on the cover. A lower stop flange is protruded on the lower section of the opening. An upper stop flange is located at a spacing with the lower stop flange. A hooking edge is protruded on the inner side of the aperture. The tear ring has upper and lower rings, ribs arranged to link the rings, an outward flange protruded on exterior of the upper ring, an upper abutting edge protruded on the inner side of the upper ring and a lower abutting edge protruded on the inner side of the lower ring. The safety bottle cap allows the cover to be opened smoothly without spurs on the aperture, thus realizing anti-burglary identification and improving protection against mouth injury.

A bottle is assembled with an existing cap on its threaded neck to seal the contents in the bottle. A decorative top fits onto the existing cap and bottle for holding a decorative body, such as a figurine or the like, on a stem of the top. To open the bottle and use the decorative top, a removable rim comes off the top allowing it to be removed from the existing cap. The cap then twists off the bottle's neck and can be discarded. To reseal the bottle and allow drinking of its contents, the top with the removable rim detached threads onto the bottle's neck. A spout or valve of the top's stem can then be opened so contents of the bottle can be drunk from the stem.
