Abstract: A child-resistant dispensing closure fabricated from resilient material which has an inverted cup-shaped body, an axially protruding nozzle and a saucer-shaped lid for closing the nozzle. The lid is connected to the body by a flexible hinge which is unitary with the body and the lid and which is located at one edge of the body. There are cooperating means for retaining the lid in closed position overlying the body and the nozzle, the catch means being located diametrically opposite the hinge. The lid has a maximum diameter no greater than the diameter of the top of the body. The catch means may be at least partially disengaged by moving the lid laterally relative to the body in a direction transverse to the diameter extending between the hinge and the catch means which also protrudes a portion of the lid radially beyond the top of the body. By grasping the protruding portion of the lid, the lid then may be swung angularly away from closing position.

Abstract: A child-resistant overcap for a pressurized container, such as an aerosol can, having a valve with an axially protruding discharge nozzle which must be depressed to actuate the valve for discharging the contents of the container. The overcap includes a valve guard moveable between an outer position in which a portion of the guard overlies the nozzle for preventing actuation thereof and an inner position in which the nozzle can be depressed. The overcap includes a resilient portion of the guard which biases the guard toward outer position and which must be overcome in order to move the guard to inner position and which returns the guard to outer position when the guard is released.

Abstract: A child-resistant dispensing closure consisting of a one-piece molding of resilient material that comprises an inverted cup-shaped cap having a central dispensing opening and a saucer shaped lid that is integrally hinged to the cap at one edge thereof for movement to and from an inverted, closing position closely over-lying the cap. The lid has an element which closes the dispensing opening and engages in telescoping relationship therewith. The cap and lid have overlapping catch means for retaining the lid in closing position. In the closing position, no part of the lid extends beyond the margin of the cap so there is nothing which a small child can grasp in order to swing the lid to gain access to the content material. The hinge is double acting and provides not only for angular movement to and from the closing position but also for lateral movement of the lid relative to the cap against the resilience of the engaged element and opening for disengaging the catch means.

Abstract: A one-piece dispensing closure consists of a cup-shaped cap having means for retaining it on the neck of a container and a lid which is connected by an integral hinge to the cap at one edge thereof and which is adapted to be swung over on top of the cap There are openings through the top of the cap and through the lid, one of which is closed by a stopper element when the lid is swung over and pressed down into closed position against the top of the cap. The relative positions and sizes of the opening in the lid and the stopper element are such that the stopper is withdrawn from the opening when the lid is lifted angularly a short distance to open position by raising the edge of the lid opposite the hinge connection. The cap and lid have cooperating means for limiting the normal, upward, angular movement of the lid away from closed position to open position.

Abstract: A tightly fitting lid for a pail or bucket has a dispensing opening for discharge of the material contained in the pail and a child-resistant closure for the opening. The lid and pail constitute a package for particulate material. The lid and pail have co-operating rib and recess for retaining the lid on the pail. The lid opening is provided by a short "wide-mouth" neck which is threaded to mate with threads on the closure. The lid and closure have at least one interengaging stop and lug, respectively, which prevent the closure from being unscrewed. The closure can be removed after it is radially deformed in order to disengage the lug from the stop. The diameter of the closure is such that the closure lug cannot be disengaged from the stop by a child of tender years whose hand is too small to span the closure. The lid also has a plurality of horizontally extending webs surrounding and spaced from the closure for supporting a superposed pail.

Abstract: A one-piece child-resistant dispensing closure for a container which has an open end. The closure has a skirt which mates with the end of the container and a top which spans the space defined by the skirt. Preferably there are two dispensing openings through the top, each of which is surrounded by an upwardly extending rim. The closure also comprises a lid for each opening and a hinge for each lid. The hinges and lids are integral parts of the closure. The lids have similar rims which fit around the rims on the closure top when the lids are swung over to close the dispensing openings. In the closed position, ribs on the edges of the pairs of opposed rims snap over each other and ears on the inner sides of the lids are closely spaced from a fulcrum on the closure top. The engagement of the ribs holds the lids closed. Pry means, such as a coin or blade, may be inserted between the fulcrum and a lid ear to pry the particular lid open.

Abstract: 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.

Abstract: A container having a tubular neck and a cup-shaped cap, the container and cap having twist action retaining means such as cooperating threads, in which the container and the cap also have child-resistant locking means. The child-resistant locking means consist of at least one set of co-operating stop and lug, preferably two each. When the cap is turned onto the neck to closed position, that one of the stop or lug on the cap is turned clockwise beyond engagement. The stop has a lug engaging abutment face which is inclined backwardly from its outer edge in a counterclockwise direction. When the cap is turned in retrograde direction toward opening, and the lug engages the abutment face it is urged radially inwardly to more strongly resist unscrewing the cap. The stop and lug are disengageable by radially outwardly deforming the portion of the cap on which one of the stop or lug is formed.

Abstract: Child-resistant locking means for a container and a cap therefor. The container has a tubular neck and the cap has a circular top and an annular skirt. The container neck and cap have interengageable threads for retaining the cap on the closure. The child-resistant locking means consist of an outwardly extending stop on the container neck and a cap lug engageable therewith to normally prevent retrograde rotation of the cap. The cap lug is located on a curved, resilient, web-like member which extends around the base of the cap and which has outwardly extending struts to space it from the cap. The cap lug is located about 45.degree. from one of the struts. In the preferred embodiment the resilient member is a complete ring, either circular or oval or a similar shape. Squeezing the resilient member inwardly along a diameter spaced about 45.degree. from the cap lug bulges the member outwardly at the lug so that the lug clears the container stop when the cap is rotated for removal.

Abstract: A child-resistant medicine vial, or the like consisting of a container and a cap therefor. The container has a hollow body and a tubular neck and the cap has a disc-like top and two concentric depending skirts. The inner skirt is adapted to be inserted into the open end of the container neck. The container has an outwardly extending annular flange which is spaced below the open end of the neck. The outer cap skirt is relatively flexible and extends telescopingly over the open end of the container, the bottom edge of the skirt reaching down into contact with or at least close to the flange. At least one upwardly extending ramp on the flange is engageable by a lug on the lower margin of the outer cap skirt. When the outer cap skirt is not stressed, the lug lies radially outside of the circular path defined by the ramp.

Abstract: Child-resistant locking means for a container having a threaded neck and a closure therefor. The closure has an inner threaded skirt and an outer more flexible skirt on the lower margin of which there is at least one axially extending, depending lug. The container has an abutment near, but spaced radially from, the base of the neck. The abutment has a face that lies in a radial plane of the container and an outer surface that extends inwardly from the outer edge of the abutment face angularly across the normal circular path of the closure lug. When the closure is turned onto the container neck, the lug (1) engages the outer surface of the lug and is flexed outwardly thereby, (2) snaps inwardly after it is turned beyond the abutment and (3) engages the radial face of the abutment when the closure is turned in a retrograde direction. In order to remove the closure, the outer skirt and the tab manually are squeezed inwardly so as to pass the abutment.

Abstract: A child-resistant package for liquids consisting of a container and a cap therefor. The container has a narrow tubular neck and a protruding concentric spout of diameter less than that of the neck so there is a shoulder at the base of the spout connnecting the spout to the container neck. The spout has an annular lip and a circular rib on its exterior that is located between the shoulder and the end of the spout. The rib has conical upper and lower surfaces which meet at a circular apex. The lower conical surface defines with the neck an angle which is greater than the angle defined between the upper conical surface and the neck. The package includes a cup-shaped cap which fits over the end of the spout.

Abstract: A child-resistant cap and neck finish for a container. The cap has a disc-like top and a depending skirt. The cap skirt and container neck have mating threads, which may be single or multi-start. The cap skirt has a lower, generally annular, or slightly oval locking collar that is connected to the threaded skirt only by flexible webs. The cap skirt and collar are unitary. The collar and the container neck have cooperating child-resistant means which are disengaged by squeezing the collar radially inwardly from opposite sides to bulge it outwardly in the direction normal to the direction of squeezing. The child-resistant elements on the collar are thereby moved out of engagement with those on the container neck and the cap may be turned in a retrograde direction.

Abstract: Child-resistant locking means for a twist-action cap for a container. The locking means has two cooperating parts. There is an abutment on the container near, but spaced radially from, the container neck and a tab on the cap which engages the abutment and prevents retrograde rotation of the cap. The tab is flexed inwardly in order to be moved past the abutment both when the cap is screwed onto the container neck and when it is desired to remove the cap from the container neck.

Abstract: A combination threaded cap and neck finish for a liquid container having mating threads on the cap interior and the exterior of the neck and also having second cooperating cam means on the cap and the container neck for applying downward thrust to the cap to maintain liquid tight sealing of the container neck even when the cap is rotated in the loosening direction through an angle relative to the container neck so as to disengage the downward thrusting surfaces of the mating threads. Some embodiments of the invention also have child-resistant cooperating means which prevent removal of the cap unless such means are disengaged by a separate and different manipulation.

Abstract: A substantially leak-proof and child-resistant combination closure comprising a container and a cap. The container has a neck and the cap has a tubular skirt which fits over the container neck, a disc-like top and resilient annular shoulder portion. The cap skirt and bottle neck have cooperating means for retaining the cap on the container. There is a sealing liner beneath the top of the cap which engages and seals the open end of the container neck. The cap skirt and the container in some embodiments have cooperating locking means which are engaged when the cap is moved down to normal closed position on the bottle neck. The locking means function to render the closure child-resistant. Other embodiments have tamper indicating means. The resilient shoulder portion of the cap flexes to compensate for tolerance variations in the cooperating retaining means on the cap and container neck in order to insure that the cap liner seals the neck of the container.

Abstract: A combination threaded cap and neck finish for a liquid container having mating threads on the cap interior and the exterior of the neck and also having second cooperating cam means on the cap and the container neck for applying downward thrust to the cap to maintain liquid tight sealing of the container neck even when the cap is rotated in the loosening direction through an angle relative to the container neck so as to disengage the downward thrusting surfaces of the mating threads. One embodiment of the invention also has child-resistant cooperating means preventing removal of the cap unless such means are disengaged by a separate and different manipulation.
