A closure having a device for lifting a liner from a container opening. The lifting device being a finger projecting from a hinge connection within the closure. The hinge connection is positioned from a depending skirt of the closure. The hinged finger disengages the liner from a sealing engagement with the container while engaging along substantially the same annulus spaced from the liner edge. A plurality of the hinged fingers may be used for the lifting device. The closure may be used in various retort and aseptic applications, as well as provide for tamper indication.

A child-resistant package consists of a container having an open-ended neck and a cap having a top and an annular skirt which telescopes over the container neck. There are co-operating snap-over retainers on the exterior of the neck and the interior of the cap skirt which require the cap to be moved axially a distance greater than the axial over-lap of the retainers in order to remove the cap. The container neck and the cap skirt also have a radially extending lug and a circumferentially extending ramp that are moved into engageable alignment by flexing the cap skirt inwardly. The ramp has a surface which is inclined relative to the axis of the neck and cap skirt and which has an axial height greater than the distance of axial over-lap of the retainers. In order to remove the cap, the skirt is flexed inwardly to align the lug with the ramp surface and the cap is rotated relative to the container neck causing the cap to be moved axially a distance sufficient to disengage the over-lapped retainers. A stop bar is formed near the beginning end of the ramp which is spaced circumferentially from the ramp a distance only slightly greater than the circumferential width of the lug so that the lug must be inserted into such space when the skirt is flexed inwardly in order to engage the lug with the ramp when the cap is rotated relative to the container for removing the cap.

A dispensing system having a reverse taper dispensing orifice seal. The reverse tapered seal depends from a lid of a flip-top closure providing a sealing engagement with a dispensing spout of the flip-top closure body when in a closed position. As the dispensing spout may have a variety of shapes, the reverse tapered seal is shaped to conform to the irregularities of the contacted surfaces of the dispensing spout. The decreasing thickness of the reverse tapered seal decreases the complexity of the molding process as well as minimizing the weakening or breaking of the seal during removal from the mold cavity.

A one-piece dispensing closure has an annular skirt on the inner side of which there are threads which co-operate with threads on a container neck for retaining the closure on the container. The closure has a disc-like top in which there is a dispensing opening and a lid for the opening which is an integral part of the closure and is hinged to the closure top at one edge thereof. The lid has an integral plug adapted to close the dispensing opening when the lid is swung into closing position overlying the closure top. The closure top and the underside of the lid have co-operating projections, for example, ears and a post, which function to prevent the lid from swinging to closing position when the closure is turned over to position for dispensing content material and which can be manually interengaged for retaining the lid in closing position when desired.
摘要:
A child resistant cap including relatively thin threads which, when the cap is in a relaxed condition, are spaced from the bottle neck, said spacing permitting the cap to be squeezed inward at points on opposite sides of the cap so that the cap responds to the squeezing by expanding outward at points ninety degrees from the squeezing points so that stops on the cap at the cap expanding location will miss the stops normally engaged when in a relaxed condition, thereby permitting the cap to be removed from the bottle. The cap may also include a guide ring in the cap interior to guide the cap over the bottle neck to help ensure that the cap is centered on the bottle opening. The cap may include pressure pads on the cap skirt outside near the cap bottom showing the user where to press and stiffening the portion of the cap where pressure is to be applied. And, the cap may include a tamper indicating ring which will separate from the cap the first time the cap is removed from the bottle. Furthermore, in an alternative cap and bottle combination, an imaginary line connecting the cap threads and an imaginary line defined by the bottle neck will intersect at an angle of from one to eight degrees, thereby providing an increasing gap between the cap threads and the bottle neck as one gets further from the cap top, this angle creating non-vertical changes to the cap or the bottle or both.
摘要:
A two stage dispensing cap for a carbonated beverage container is described. The cap has a flip top which is hingedly connected to a collar wherein the collar is rotatable on the container. The cap, upon rotation of the collar, is first opened into a venting position wherein the flip top vents the pressurized contents of the container but remains locked partially closed. Continued rotation of the cap releases the locked flop top to allow the container to be fully opened. A set of cams on the container neck work in conjunction with annular beads to first allow partially opening of the flip top into the venting position and then allowing it to fully open.

A mold for forming a container is provided with an upper die, a lower die, a first semi-cylindrically shaped collar and a second semi-cylindrically shaped collar. The upper die includes a downwardly-depending central core portion which cooperates with a concentric annular lip portion and spaced outwardly from the central core portion defining a groove therebetween sized to provide a continuous neck finish on the container. The lower die is provided with a core-receiving pocket sized to receive the central core portion of the upper die. The first and second collars are disposed in abutting relation and are provided with mating surfaces having thread grooves to form a thread region of the container neck, the first and second collars being sandwiched between the upper and lower dies in a use condition.

A closure cap includes a top wall with recesses therein wherein the recesses have an unpleasant tasting material therein to discourage infants and small children from placing the closure caps in their mouths and biting down on the caps.
摘要:
A container and closure assembly having complementary engaging threads on the closure and container which are used for closing the container but which do not afford opening movement because of a one-way stop arrangement. Opening movement requires orientation to a predetermined location followed by tilting of the cap to open the container and remove the closure therefrom.
