Abstract: A moisture proof vial and closure system are provided which may be used in a child-resistant mode or in a non-child resistant mode. In the child resistant mode locking lugs 22 on the closure are interlocked with bayonnet slots on the vial. A non-child resistant operation in a moisture proof system may be achieved by leaving the locking lugs 22 off of the closure skirt wall 20 and by adding a detenting means 51 inside of the container to engage and hold a sealing plug 39 against sliding outwardly of the container because of the lack of locking lugs on the closure 10A. A simple push inward will force the sealing plug 39 home to its sealing position to seal the medicine in the vial, and a simple pull on the closure to pull the fitment from the detenting means is needed to remove the closure. The preferred detenting means 51 is in the form of radially inwardly directed projections 52 formed on the interior container wall to abut and restrain the sealing plug against inadvertent sliding from the container.

Abstract: A child-resistant package characterized by a container with a threaded neck portion, a closure provided with a multiplicity of threads cooperatively engaging the threads on the neck portion, means connected to the threaded neck portion for stopping the threading rotation of the closure onto the threaded neck portion at a predetermined position, and resilient liner means interposed between the underside of the top of the closure and the top of the neck portion.

Abstract: A two member child-resistant closure assembly including an outer shell and an inner resilient closure retained therein. In the child-resistant mode, the resilient inner closure spring biases the outer shell into locking engagement with lugs formed on a cooperating container. A handling ring is provided for removing the inner closure for use separately as a snap cap. For this purpose, the inner closure includes an annular plug, and a short annular skirt arranged to engage the container rim.

Abstract: A locking means for a threaded container and closure has been invented. The locking means comprisesA. a container having a neck portion; and on the external surface of said neck portionI. a continuous first thread;II. a ring adjacent the terminal end of said thread;III. and at least one lug havinga contacting surface diagonally aligned with said first thread; an upper surface adjacent to or lower than said ring; and a height and radial thickness greater than said ring;B. a closure havingI. a radially flexible inner flange, the terminal end of said inner flange coordinating with the internal surface of said neck; andII. an outer flange havinga continuous second thread coordinating with said first thread; and at least one tab adjacent the initial end of said second thread whereby said closure is threaded onto said container, said tab passes onto said contacting surface and is then engaged by the terminal surface of said lug.

Abstract: The invention contemplates safety-closure structure involving threaded engagement of cap and bottle-neck members, wherein coacting lug formations on the respective members have compliantly yieldable cammed latching engagement in approach to a fully-closed relation of the members and wherein, once in the fully-closed relation, a positive-lock relation prevents unthreading rotation of the members. The engaged threads are sized for a quantum of axial lost-motion, and resilient action of a seal which reacts axially between the members is operative to constantly load the cap member to its axially upper limit of the lost motion. The lug formations are of such axially limited extent that, when the members are in their fully-closed relation, an axial depression of the cap member through the lost motion and against the resilient seal action is necessary to free the positive-lock relation of the lugs formations, thus then permitting a thread-off rotary manipulation of the cap member.

Abstract: A convertible child-resistant closure comprises an outer closure and an inner resilient liner. When applied to a cooperating container in the child-resistant mode, the resilient liner is distorted between the container rim and abutments formed on the outer closure panel, thereby providing an upward locking bias to the closure. The upper surface of the liner includes depressions adapted to receive the abutments only when the liner and the outer closure are in a particular relative angular orientation. To convert the assembly to a closure which is not child-resistant, the liner is removed and reoriented so that the abutments are received within the depressions, thereby preventing the abutments from distorting the liner to provide the locking bias.

Abstract: A closure assembly comprises two separable closure members which are pre-assembled in coaxially stacked relationship, with their top panels aligned in the same direction. The lower closure member of the stack assembly comprises locking elements which are engagable with cooperating locking elements on a container, thereby providing a child-resistant closure. The upper closure is a simple snap cap, plug cap, or other closure which is not child-resistant. The upper closure is removably attached to the lower child-resistant closure by an interference fit between resilient attachment members integrally formed as parts of the upper and lower closures. The assembly can be separated, for use of the upper closure only for sealing the container, thereby providing a choice between a child-resistant and non child-resistant closure.

Abstract: The container comprises an open-topped cylindrical container body having a pair of tabs on the upper end of the outside, and a removable cylindrical resilient cap, having a sidewall with vertical grooves on the inside matching the tabs in location, but closer together diametrically than are the tabs. The cap is deformable to accommodate the tabs. The sidewall also has a pair of about horizontal arcuate grooves extending from the vertical grooves larger diametrically than the vertical grooves to receive the tabs. The horizontal grooves may narrow as they diverge from the vertical grooves. The cap cannot be removed from the container body without first rotating the cap to free the wedged tabs, then ovaling the cap to allow the cap to be rotated to a position where the vertical grooves and tabs are aligned, whereupon the cap can be lifted off the container body.

Abstract: A safety closure and container combination is disclosed. The container and closure each have mating lugs which cooperate with each other to move the closure toward the container when rotated in a first direction and to move the closure away from the container when moved in a second direction. Cooperating stop surfaces are provided on the closure and container which engage when the closure is rotated in a direction to move it away from the container so that it is necessary to move the closure toward the container to allow the stop surfaces to move past each other thereby allowing the closure to be removed from the container.

Abstract: A medicine container of opaque or translucent material is provided with an aperture to allow one to clearly view the contents of the container. In one embodiment of the invention, the container is characterized by a transparent window in the cylindrical side wall thereof, while two other embodiments provide for a transparent bottom to the container.

Abstract: A two piece combination of a container and cap, wherein the neck portion of the container and the flange of the cap have interengaging locking elements for securing the pieces together. A generally cylindrical flexible wall is an extension of the container neck, and terminates in annular free end perpendicular to the container neck. This annular free end engages an internally beveled surface of the cap, such that when the locking elements are engaged, the annular free end is deflected radially inwardly to provide an axially biasing force maintaining the elements engaged and also providing a seal between that member and the cap beveled surface.

Abstract: A cap and container are incorporated in a combination having apparatus to provide a convertible feature such that a selection can be made between, on the one hand, a precautionary arrangement to prevent children from obtaining access into the container and, on the other hand, an easy open arrangement.

Abstract: A container safety closure including a spring element in the form of a generally convoluted tubular plastic element preset to a stable condition, where its further compression response is determined by special tapering of the wall thickness and radii of the convolutions. The spring element biases a container closure member against a detent arrangement and the spring must be compressed to permit the closure member to be removed from the container.

Abstract: A single piece threaded safety closure for sealing the open end of a container. At least three enlarged members are equi-angularly spaced about the closure thread and form locking shoulders adapted to inter-engage corresponding shoulders defined on the thread of the container to lock the threads together and prevent removal of the closure except by special manipulation. A resilient liner is compressed when the closure is drawn down on the container and the compressed resilient liner urges the cap upwadly and maintains the shoulders in locked engagement.

Abstract: A child-proof container and cap combination is disclosed which seals the contents of the container against moisture vapor deterioration by making a seal which is "tight" by industry standards. The cap requires less than seven inch pounds of torque for removal. The seal is obtained by the cooperation of a flexible sealing lip on a separate element supported or disposed on the interior surface of the cap and cooperating with a rigid tapered sealing surface on the container.

Abstract: The version of the container of my U.S. Pat. No. 3,991,895, which provides a dual latching arrangement so that, by a first turning of the cover during the latching operation, a condition of easy opening for adults is obtained, and, if desired, a hard-to-open, child-resistant condition is obtained with a further turning of the cover, is improved by the provision of a positive stop at the end of the first turning of the cover to prevent inadvertent latching into child-resistant position and to require a positive, downward displacement of the cover before it can be turned into child-resistant condition.

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: The invention contemplates selectively openable closure means that is tamper-proof, in the sense that a correct sequence of two deliberate and independent movements of two parts is necessary in order to achieve access to the contents of the bottle or the like which is protected by the closure.The specific construction that is described involves a bottle with a neck having a circular opening, and a closure cap having a cylindrical wall to overlap and lock to the outer surface of the neck. The closed end of the cap has an axially projecting stiffly yieldable annular section which engages a chamber at the circular neck opening, in the course of closing the bottle. The nature of the lock is such as to avoid "plugged" closure and to compliantly preload the yieldable engagement, utilizing the resilient action to retain the lock and to establish a liquid seal of the bottle contents.

Abstract: The invention relates to a container with a pocket for holding pills and the like. A pocket member is formed within a container and is adapted to hold a number of pills or the like being held by the main body of the container. This allows an individual to separate out a daily dosage of pills in the pocket from the rest of the pills in the container in order to facilitate prevention of taking two few or too many pills. A single cap may close both the pocket and the main body of the container.

Abstract: A safety cap and container is disclosed which is resistant to accidental opening. Such a cap and container include cooperating ratchet means on the cap and the container which normally hold the cap against undesired movement with respect to the container. A tapered internal surface is provided in the container and an internal resilient dependent member is provided on the cap so as to engage the tapered surface. Such engagement normally holds the ratchet means so that the cap cannot be moved with respect to the container. When, however, pressure is applied to the cap above the dependent member, this member is deflected by the tapered surface so as to allow movement of the cap so as to disengage the ratchet means, permitting the cap to be removed from the container.
