Abstract: A bottle cap which comprises an edge, a crown, a convex top on the crown, a cone at the interior center of the convex top, and a projection on the edge. The bottle cap is constructed in such way that after the cap is put on the mouth of the bottle, there is a clearance between the apex of the projection and an aluminum foil covering the mouth of the bottle. When the convex top is depressed with the thumb, the cone is lowered to pierce the aluminum foil, while the cap is opened by pushing the projection with the index finger. The bottle cap eliminates the need to pierce aluminum foil with a finger or other object. Accordingly, the liquids in the bottle will not be contaminated by the finger or other object before drinking. This meets economical, sanitary and easy-to-open requirements.

In accordance with the invention, the vessel surface extent is adapted for engaging the telltale and is configured to effect first and second different engagements therewith respectively in the course of the first and second sense movements. With such facility, the vessel permits the telltale to be moved into closure relation with the sealing surface and to be selectively positively restrained from movement relative to the mouth in the initial phase of the second closure member movement.

Abstract: An inner seal for a container which has a hollow body for holding material, a threaded neck extending from the body to terminate in a lip which defines an opening, and a threaded cap for screwing onto the neck over the opening. The seal is comprised of a thin sheet of fracturable material for placement over the opening onto the lip. The peripheral portions of the material extend downwardly about and adhere to the exterior of the side walls of the neck. The seal is dimensioned to cover some of the threads of the neck so that screwing the cap onto the neck will aid in securing the seal about the side walls of the neck.

Abstract: This bottle has a projection or "latch" from its neck, just below the thread, and along and near the lower end of that thread. There is a gap in the cap thread, that lines up with the "latch" when the cap is fully screwed on. The cap deforms when screwed on, passing the "latch" over the end of the cap thread and into the gap. The "latch" then resists cap removal. Only torque beyond the ability of a small child (or even requiring use of a tool) frees the cap. A second projection from the neck, a "flag", is breakable. It is below the bottom end of the neck thread, just above (measured along the thread) the "latch". The "flag" can fold against the neck, but springs out if released. It catches in the cap-thread gap when the cap is unscrewed, and is torn off or broken by forcible removal of the cap. Its removal or breakage evidences that the bottle has been opened.

Abstract: A tamperproof package comprising a container having a neck and an annular radial flange beneath the neck and a plastic closure removably interengaged with the neck. The closure has a top wall and a peripheral skirt. A plastic pilfer band interengages the skirt, such that when the closure is applied to the container, the band is flexed over and engages beneath annular flange on the neck of the container, and when the closure is thereafter removed from the container, the band is prevented from removal from the container and is thereby disengaged from the closure. In a modified form the plastic pilfer band includes an integral liner which is severed from the band and engages the top wall of the closure during assembly of the band to the closure.

Abstract: A tamper indicating plastic cap for twist application to a threaded container neck comprises cap, body and a band interconnected to the cap by a plurality of bridges. Each of the bridges slopes upwardly in the direction of twist application of the cap to the container. A plurality of drive devices have co-operating abutments on the cap and band which are normally disengaged. The bridges flex as the band is snap-fitted over a bead on a threaded container shoulder in a manner which enhances the movement of the cooperating abutments towards one another as the band moves upwardly towards the cap. The abutments engage to drive the band with the cap to prevent breaking of the bridges as the band is snap-fitted over the threaded container neck. The bridges readily break when the cap is unthreaded from the container neck with the band engaged with the container bead. Such arrangement substantially facilitates the injection moulding of the cap because the band is significantly spaced from the cap underside.

Abstract: A thermoplastic container is shown having an insert sealing the container. The insert includes a membrane which can be pierced to provide access to the inside of the container to draw off a substance such as a sterile liquid. The insert is held by a retaining structure which receives and seals with the insert.

Abstract: A slide type cap closure is disclosed comprising a cylindrically shaped closure member and a slidably interfitting disk member. The closure member forms a seal about the opening of the container on which it is mounted and includes an orifice extending upward from a recess formed along the top surface of the member. The recess has a pair of grooves extending along its length into which downwardly depending rails of the disk member slidably interfit. The disk member is dimensioned so as to move in a snap action manner along the upper surface of the closure member between open and closed positions. The disk member does not extend beyond the periphery of the closure member. The disk member in combination with the slightly protruding upper termination of the orifice forming member forms an extremely tight seal with the orifice when in the closed position.

Abstract: A tamperproof sterile solution closure system which will permit the machine assembly of the closure cap to the container without engagement of the threads of the cap with the container threads. The screw type cap member has internal threading, a tear-away portion and a skirt portion. The container has an abutment surface for sealable contact with the skirt portion and in a position such that the threads in the cap and on the neck are not engaged. To activate the closure, a tear-away portion is removed which will allow the threads to engage. Simultaneously, a contact portion on the cap will engage a weakened flange in the neck to cause it to be separated. A projection extending from the cap is positioned in an annular recess in the cap to serve as a captive means for the separated dome portion of the cap for replacement purposes.

Abstract: An improved closure for a bottle containing a gas-emitting solution. The closure is screwed onto the bottle and includes a disk member having a centrally disposed opening. The opening is sealed with a rupturable seal member. Two concentric, cylindrical members are disposed about the opening.

Abstract: A safety closure of the type having a unitary construction with a closed top from which an interiorly threaded skirt depends and a container having an exteriorly threaded neck on which the closure is mounted in sealing relationship. The safety closure has at least one locking member formed integrally therewith which is movable under the action of actuating apparatus between a non-locking position and a locking position in which the locking members engage appropriate corresponding locking elements provided on the neck of the container. The actuating apparatus is constituted by the top of the closure which has a dish-like configuration formed such that the application of a sufficient finger pressure on the top will result in the movement of the locking members from the locking to the non-locking position.

Abstract: The screwcap comprises an inner cap and an outer cap. The outer cap is threaded on a container neck. The screwing action presses the inner cap and its sealing layer in an axial direction against the opening edge. An outer edge portion of the inner cap projects radially over the neck and is at a first distance over a projection on the inside of the outer cap collar. The projection only contacts the outer edge portion of the inner cap when the outer cap is unthreaded. Continued unthreading movement initially only raises the inner cap from the opening edge at a locally defined peripheral point through engagement of the projection on the lower edge of the inner cap outer edge portion, prior to complete raising of the inner cap, to eliminate a vacuum in the container. This reduces the force necessary for opening the screwcap.

Abstract: A reclosable valve stem actuated valve structure for aerosol-type containers and the like which valve structure is provided with a preassembled but removable external seal.

Abstract: A tamper indicating dispensing closure for containers in which a cylindrical cap has a passage for dispensing the contents of the container and the passage is closed by a member requiring movement relative to the remainder of the cap. The entire top of the cap is covered by a tamper indicating element which is permanently attached to the remainder of the cap so that the element must be removed in order to perform the opening operations of the closure and such removal results either in the destruction of the element or in the means fixing it to the cap to visually indicate that the closure has been opened or placed in a condition for opening.

Abstract: A tamper-proof resealable closure formed by a cap with an elongated neck that is integrally sealed to a housing. The neck includes a set of outer ribs which guide the cap into the housing when the tamper-proof seal is broken and the cap is depressed. The ribs are configured relative to the housing to further provide a relatively moisture-proof seal between the cap and the housing when the cap is rotated after having been depressed into the housing. The temporary moisture-proof seal is released by simple rotation of the cap to its original position of depression. The cap is removable and temporarily resealable as desired.

Abstract: A tamper-proof closure arrangement for a container includes a shrinkable seal applied to seal receiving surfaces of the container and closure cap such that the seal is applied internally of the closure cap without removing the closure cap. In a preferred embodiment, the seal surfaces comprise three-dimensional surfaces formed on the container neck and on the closure cap internally of a skirt portion of the cap. The seal is visible through the closure cap such that any attempt at removing the cap irreversibly damages or deforms the seal to provide a visual indication of tampering.

Abstract: A tamper-indicating arrangement for a container is disclosed which functions to provide a clear visual indication that the container has been opened. The arrangement includes a closure which is adapted to be fitted to the container, and further includes first and second coacting means for respectively retaining the closure on the container in distinct first and second positions with respect to the container.

Abstract: The invention contemplates a container closure, with a frangible cover preassembled thereto, such that both the closure and the cover have independent snap-lock engagement to the container-neck finish, in a single axially displaced assembly of both of the preassembled parts to the neck finish. The cover must be broken to gain access to container contents, so that any breakage provides a direct warning as to possible tampering. In the disclosed embodiment, the closure which remains after destruction and removal of the cover, has child-safety features, in respect of its snap-action engagement to the neck finish.

Abstract: It is difficult to detect whether the rubber seal on a vial or on a hypodermic syringe cartridge has been penetrated, because the rubber seal over the mouth of the container is purposely soft and self-sealing to prevent contamination of the fluid within the container. As a result pilfering of narcotics from such containers has gone largely undetected. To remedy this situation, a blister-like sac of a plastic film and containing a harmless dye is mounted within the mouth of the container between the rubber seal and the contents of the container. It is impossible for a hypodermic needle to be inserted through the seal and into the fluid within the container without puncturing the blister-like sac and thereby releasing the harmless dye into the fluid within the container. Thus, if the seal has been broken, the fluid in the container will be tinted with the color of the harmless dye.
