Abstract: A method and apparatus for removing a liner from a formed metal closure by at least partially everting the closure with an advancing punch adapted to temporarily couple the everted closure. By everting the closure, the liner becomes accessible to be retained within the closure support and is separated from the closure when the punch is retracted. A stripper is provided adjacent the punch to separate the everted metal portion of the closure from the punch.

Abstract: The closure consists of inner and outer caps which are disposed concentrically about the mouth of a container. A flap or latch is cut into the side wall of the inner cap and the latch is biased such that its upper edge is normally disposed beneath a lip formed in the brim of the container to lock the inner cap about the mouth of the container. The outer cap is maintained concentrically about the inner cap by means of the lower edge of the latch which is accommodated in an annular groove formed in the inside wall of the outer cap. The caps may be removed from the container by first forcing the outer cap downwardly relative to the inner cap. As the outer cap moves downwardly the wall of its groove contacts the lower portion of the latch and causes the latch to pivot to a position at which its upper edge is no longer beneath the brim lip. Secondly the inner cap is grasped along with the outer cap and the two caps are removed together as a unit from the container.

Abstract: A safety closure is provided for closing the open neck of containers having a bead type finish formed on such neck end. The closure comprises a unitary element molded from a resilient plastic material and having a generally horizontal circular panel portion and an integral, generally vertical peripheral flange portion. The flange portion is provided with an internally projecting rib which snaps into engagement with the groove normally provided beneath the bead of a container bead finish. In the closed position of the closure on the container, the bottom edge of the closure flange is flush with the side wall of the container neck and cannot be engaged by the fingers to pry the closure off of the container.

Abstract: An improved safety closure for containers of harmful products includes an inverted cup-shaped body member formed of resilient plastic material and an integrally molded locking flap connected by an integral hinge to the top periphery of the body member. The locking flap folds into a conforming recess in the top surface or panel of the body portion, and, in its folded position, all edges of the locking flap are flush with the adjacent surface of the panel. One or more dispensing openings are provided in the panel and sealing means are provided on the bottom of the flap to close the dispensing openings in the folded position of the locking flap. Two distinct sets of cooperating locking surfaces are provided on the flap and body portion to retain the locking flap in its folded position. The one set requires a vertically downward pressure on a specific area on the panel to release.

Abstract: A closure structure for a vial or container, preferably of the two-compartment type, wherein lyophilized medication is contained in one compartment and a solvent is contained in the other compartment with a displaceable, moisture-proof plug disposed between the two compartments. The closure structure is comprised of a stopper which is partially inserted into the neck of a vial and is covered by a cap member having a fastening portion for securing the cap member to the open end of the vial neck and a sleeve portion of reduced diameter which snugly surrounds the protruding portion of the stopper and is disconnectible from the fastening portion in order to move with the protruding portion of the stopper into the neck of the bottle under manually applied pressure. A dust shield is secured to the free end of the sleeve portion and is preferably removed after which the needle of a syringe can be inserted through the stopper to communicate with the interior of the vial.

Abstract: An improved security container and closure apparatus including a generally cylindrical container having a closing base portion at one end and an open mouth at the other end, a rib extending inwardly from the side of the mouth opening, and a neck portion surrounding the mouth and having an external wall provided with a circumscribing recess, and a resilient closure having a top portion and a surrounding, downwardly depending skirt portion, the skirt portion having an inwardly extending bead matingly engageable with the recess of the neck portion of the container.

Abstract: A seal cap assembly for a reservoir casing comprises a first seal cap having an annular thick rim portion detachably secured over the upper opening of the casing and a vertical expansible diaphragm formed in a piece with the inner periphery of the rim portion to be disposed within the casing and a second cap assembled with the thick rim portion of the first cap to facilitate removal of the cap assembly from the casing by a pushing force given to the second cap.

Abstract: A resealable container comprising container means and closure means adapted to sealingly cooperate with said container means, said container means having a sidewall with at least one open end portion defining an opening, said open end portion having first sealable means for enabling the formation of two separate and positive seals substantially about the periphery of said open end portion, said closure means including, in integral combination, a generally peripheral shoulder portion being adapted to be seated on said open end portion, a flange portion connected to said shoulder portion and defining second sealable means for sealingly interfitting and cooperating with said first sealable means to provide the two separate and positive seals, and flexible means for enabling quick and easy engagement and disengagement of the two separate and positive seals formed by said first and second sealable means in response to displacement of the flexible means.

Abstract: A cover and safety closure structure for a container having a flowable material therein includes a cap member integral with or mounted on the container and having a material dispensing aperture in a top wall of the cap member. A closure member is hingedly mounted on the cap member and is movable between an open position and a position in covering relation with and closing the material dispensing aperture. A latch member extends from the closure member and the latch member and the cap member have cooperative portions engageable one with the other for retaining the closure member in covering relation with and closing the material dispensing aperture. The cover and closure structure includes a resilient member or members mounted on one of the cap member and the closure member and engageable with the other of the cap member and closure member for urging the cooperative portions on the latch member and cap member into retaning engagement.
