The cap assembly includes a lid member adapted to fit over the open mouth of the bottle, and to support a drinking straw which extends from the lid member to a lower end substantially adjacent to a bottom wall of the bottle. An apertured cylindrical stem is carried by the lid member and may include a poppet valve or the like to selectively permit delivery of the bottle contents through the straw and stem to the exterior of the bottle. A protective closure cap fits removably over the apertured stem in sealing relation therewith to prevent leakage of the bottle contents.

Abstract: The invention relates to a closure cap having a structural arrangement which provides a frictional fitting dome attachment to the base and provides an arrangement in which any shaped dome can be fitted thereon. Moreover, hot stamped discs with decorative designs are placed below transparent domes. This allows a manufacturer to vary the cap configurations.

Abstract: This relates to an improvement of a conventional closure having a tamper evident feature in the form of a safety button. In accordance with the improvement, the surface of the safety button is provided with a coating in the form of a suitable binder incorporating rupturable microcapsules containing an FDA approved colorant. A relatively stiff layer of translucent material overlies an end panel of the closure in position to be engaged by the microcapsules and to effect rupture of the microcapsules when the safety button everts from a lower axial position to an upper axial position and the microcapsules strike against the underside of the layer of translucent material. In order to prevent accidental rupture of the microcapsules prior to the closure being applied to a container, there is incorporated in the coating spacers which normally prevent the rupture of the microcapsules during conditions of manufacture and handling.

Abstract: A closure for a resealable container comprising an annular container engaging member fixedly attached to the edge of the container and a lid having an end wall and an annular skirt, the lid being attached to and separable from the container engaging member at a failure zone. In one embodiment the lid is adapted to reseal the container after it is separated from the container engaging member by turning the lid upside down and positioning it such that the annular skirt engages the container engaging member and the end wall covers at least a portion of the opening of the container. In another embodiment, the lid is also adapted to reseal the container after it is separated from the container engaging member by positioning the lid such that the annular skirt engages the container engaging member and the end wall covers at least a portion of the opening of the container. The invention also includes a stackable container having the closure described above.

Abstract: This relates to a conventional type of closure having a central button which is normally provided with an "up" convex state and which is movable by a vacuum within an associated container to a "down" concave state. The button, as formed, has a zero or tensile stress state with the stress state changing to a compressive stress state when the button is drawn downwardly by a vacuum within the associated container. In accordance with this invention, the button has been reformed so that it is slightly flattened and this reforming has changed the zero or tensile stress state to a compressive stress state thereby providing the button with more stored energy when it is drawn downwardly by a vacuum within an associated container. This additional stored energy provides for a greater flipping action of the button which can be utilized to operate an irreversible tamper indicating system which may be applied to the button.

Abstract: A radiator cap assembly has a cap, a tether and a seal member. The seal member is adapted to float upon coolant within the radiator. Upon removal of the cap while the coolant is in an elevated temperature and pressure condition, the seal member will cover the fill tube to prevent liquid from exiting the radiator.

Abstract: A container cover provides a removable cover for placement on the surface of the liquid contents of a container, thereby sealing the liquid contents from the air-filled void of the container. The device includes a disc portion of a size and shape to adequately cover the liquid surface, a handle portion enabling manual grasping of the device for insertion and removal, and a reservoir member, preferably integral with the handle portion, which is saturated with an appropriate thinning agent. This reservoir member is exposed to the lower surface of the disc via perforations, so that it can replenish the volatile components otherwise lost by the liquid contents over time, thereby offsetting the effects of evaporation and oxidation.

Abstract: A sliding seal for the closure of a container. The closure is of the type having a portion fixed to the container and a portion hingedly secured thereto for permitting access to the interior of the container. The seal has a first segment secured to the fixed portion of the closure and a second segment extending from the first and slidably connected to the pivotal portion of the closure by means of a post secured to the pivotal portion and extending through a slot formed in the second segment. The post is capped by a washer or the like to retain the second seal segment about the post. The seal is otherwise unattached to the pivotal portion of the closure, and therefore slides relative to the pivotal portion to prevent stretching of the seal as the closure is opened.

Abstract: A top member for a beverage container which includes a scored portion which can be displaced to provide an access opening, in which the improvement relates to the provision of raised portions adjacent the access opening area to reduce or prevent spillage when drinking from the container. The raised portions can be integral with the top member and can be continuous along two side edges and the front edge of the access opening.

Abstract: A condition indicating child-resistant cap assembly including an inner cap and an outer cap rotatably mounted on the inner cap. An indicating post is connected to the top wall of the inner cap in alignment with an opening in the top wall of the outer cap. When the cap assembly is in the child-resistant mode, the outer cap is spaced upwardly from the inner cap and is freely rotatable in one direction thereon. The post is wholly contained within the space between the inner and outer caps and therefore not visible outside the cap assembly to indicate the cap assembly is in the child-resistant mode. When the cap assembly is in the non-child-resistant mode, the outer cap is rotated in the opposite direction until it snaps, and is moved downwardly toward the inner cap and rotated in the first mentioned direction, whereby the inner and outer caps are interlocked for removal from a container.

Abstract: A child resistant closure comprising an outer shell having a base wall and a peripheral skirt and an inner shell having a base wall and a peripheral skirt telescoped within the outer shell. The inner surface of the base wall of the outer shell and the outer surface of the base wall of the inner shell have circumferentially spaced radial projections which are adapted to interengage upon relative axial movement between the shells. The top wall of the inner shell includes indentations or grooves between the projections which are at a small acute angle with respect to the plane of the top wall of the inner shell. The inner surface of the outer shell has at least one inclined indentation or surface which extends radially and is also at an acute angle to the plane of the base wall of the outer shell.

Abstract: The invention relates to a screw closure of plastics material for bottles which are under pressure, comprising a cap (1) having a cap end portion (2) and a substantially cylindrical peripheral cap portion (3) with internal screwthread (7), and a circumferentially extending, inwardly projecting bead (5) at the transition between the cap end portion (2) and the peripheral cap portion (3), wherein a sealing disc (9) which is movable relative to the cap bears against the inward side of the cap end portion (2) and the projecting bead (5). In order, in regard to such a pressure-tight closure, to limit the maximum pressure up to which the closure remains pressure-tight, to a value which is noticeably below the pressure at which a bottle explodes, it is proposed in accordance with the invention that the bead has a segment-like interruption.

Abstract: A child-resistant safety cap that can be screwed on or off a container. A lock pin is slidably positioned to extend through a hole in the cap side wall into an opening in a radial flange carried on the neck area of the container, such that the lock pin acts as an obstruction into the cap rotation. Finger pressure can be applied to a partially-concealed end area of the lock pin to move the pin to a position where it can be manually pulled to a position separated from the container flange; the cap then be unscrewed from the container.

Abstract: The cone-shaped or dome-shaped sheet of waxed paper or freezer paper having a moisture retarding coating on at least the surface of the paper facing an underlying dish bearing food and positioned within a microwave oven, and being microwave transparent traps moisture condensing on the interior surface thereof for revaporization for return to the food being heated and/or cooked while preventing the dripping of condensed moisture directly onto the food within the underlying dish. Preferably the conical or dome-shaped cover is mechanically embossed to form vertically spaced annular concave cavities facing inwardly to trap the moisture running by gravity down the interior surface of the cover within the cavities for revaporization. Additionally, circumferentially spaced reinforcing ribs may be formed over the height of the cover to maintain the cover one or dome shaped configuration throughout the microwave oven heating process.

Abstract: This relates to a composite closure which incorporates the conventional closure of the press-on, twist-off type including a metal shell having in the center of an end panel thereof a tamper indicating button. The composite closure includes an overcap which is frictionally interlocked with the shell and wherein the shell has been modified so that the curl at the lower edge of the skirt thereof is outturned as opposed to being inturned and the rougher coating for receiving the sealing compound increases the frictional connection between the overcap and the metal shell. In addition, the overcap is provided with a tamper indicating band which is interlocked with the container finish so as to prevent both axial upward movement and circumferential movement of the tamper indicating band relative to the container finish.

Abstract: This relates to an improved tamper band construction for use in conjunction with closure caps for locking beneath a retaining bead on a container neck finish when the closure cap is removed to indicate rotation of the closure cap. The tamper indicating band is provided with a plurality of flaps which are initially molded in a radially inwardly, axial downwardly directed position and then are folded upwardly to radially inwardly and axially upwardly directed positions where they are engagable beneath a container retaining bead. Most particularly, the plurality of flaps are joined in groups by connecting bridges so that each group of flaps pivot as a unit with the connecting bridges stretching and providing an over center snapping action to retain the flaps in their operative positions after they are folded to such positions.
