Abstract: There are various ways to latch a closure onto a container. It has been found that for blowmolded containers that the support flange for the bottle preform can later be used as a part of the latch mechanism to secure a closure onto the container. Preforms have a support flange by which the preform is handled prior to being placed into the mold and in the mold. Prior to being placed in the mole, the preform is heated to about 85oC to about 200oC. During this time and in the mold, it will be supported by the support flange. This support flange is used after the container is blown and filled as one part of the latching mechanism of the closure. The closure will have a portion that is an interference fit with the support flange of the bottle to thereby secure the closure to the bottle.

Abstract: A closure assembly is provided that includes an outer cap with a skirt dimensioned to telescope over the open top end of the tube. An annular shoulder extends inwardly from the top end of the skirt and includes an aperture through which a needle may be directed. A laminated seal is bonded to the bottom surface of the annular shoulder of the outer cap and extends continuously across the aperture in the annular shoulder. A stopper is secured on the bottom surface of the annular seal and is dimensioned for sealing engagement in the open top of the tube. Outer circumferential portions of the bottom surface of the laminated seal between the skirt and the stopper are bonded to the open top end of the tube. The bond between the closure and the laminated seal is stronger than the bond between the tube and the laminated seal. Thus, the closure assembly retains its structural integrity after opening of the tube and can be used to reseal the tube.

The annulus extends downwardly by a distance greater than the fin and has an outer diameter slightly smaller than that of the inner diameter of the neck of the container with which it is to be used. The annulus assists with centering the closure on the container as the closure is screwed onto the container.

Abstract: A sealing cap for the mouth of a container facilitates both the sealing of new bottles containing unused contents, and the re-sealing of those bottles already in use so as to preserve their contents. The sealing cap includes an inner cap and an outer cap. The inner cap includes a shielding plate which is fixed on the mouth of a container, and an annular strip which is provided at the lower end of the outer circumferential wall of the inner cap.

By removing the annular strip from the inner cap and pressing down the outer cap, the lower end of the outer cap engages the outer circumference of the mouth of the container, and at the same time, the lower-end sharp edge of the guide tube pierces the shielding plate. The user then opens the top lid of the outer cap to access the contents of the container.

Abstract: A gift package simulating a baby nursing bottle, the package being composed of a cylindrical container housing a miniature doll or other gift and a molded plastic cap that fits on the open mouth of the container. The container is formed of transparent plastic material, the rim of the mouth being rolled to define an annular bead. The cap has an upper section shaped to simulate the nipple-cap ring of a baby bottle, a lower section in the form of a cylindrical stopper that fits into the mouth of the container, and a circular flange at the junction of these sections. Formed on the stopper section is a circumferential array of ledges which are shaped to permit the ledges to slide into the mouth of the container, the upper ends of the ledges being spaced from the flange to define a circular socket therebetween. To put the cap on, the stopper section is pressed into the mouth of the container to cause the annular bead to snap into the socket, thereby latching the cap in place.

Abstract: A container and closure assembly, affording a simple, quick, ergonomical, and reliable closing operation, provides an intermediate, partly open position that is reliably indicated.

The closure is mounted to the container by a projection that is cooperatively received in a track. Either the closure or the container may be provided with the projection, the other being provided with the track. In a preferred embodiment, the track includes a protuberance that hinders the movement of the projection past a predetermined position along the track.

Abstract: A container, preferably of small capacity, such as a school milk plastic bottle, has a neck having an in-turned lip flange, a vertical surface spaced below the lip flange and an external shoulder below the vertical surface. A second external shoulder below the first-mentioned shoulder is preferably slanted upwardly-outwardly. A cap for the neck has a top and a skirt depending from the top formed with internal bead segments which snap under the first mentioned shoulder. The lower edge of the skirt fits tightly against the second shoulder to prevent the fingernails from being used to overcome the tamper-evident feature of the cap. A tear tab (preferably chevron-shaped in cross-section) depends from the skirt. An external, vertical scoreline adjoins the tab and at its upper end is adjacent a second scoreline which is formed on the interior of the top. Pulling the tab tears the skirt from the top for about 342.degree. of its circumference.

The cross-sectional areas of the region and the cross-sectional area of the inner surface of the outlet being such that when the closure is applied to the container the deflecting section of the inner skirt engages the inner surface of the outlet to force the inner surface of the outlet adjacent the rim into sealing engagement with the sealing zone to seal the closure to the container.

Abstract: Plug for sealing or capping the open ends of tubular members, such as tubular rails or railing support members in boats. The plug has a cap from which extend upper, lower, right side and left side rearwardly projecting and connected planar panels. Each of the upper and lower planar panels and one of the side planar panels includes an outwardly protruding array of ramped teeth formed integrally therewith. The other side planar panel lacks an array of ramped teeth. The height of the teeth in each array increases incrementally from a minimum height remote from the cap to a maximum height adjacent to the cap. The ramping of the teeth allows for accommodational frictional engagement with various inside dimensions of tubular rails or railing support members to secure the plug tightly therewithin. A tapered indexing guide bar is located at the junction of the upper planar panel and the side planar panel which lacks an array of ramped teeth.

Abstract: Plug for capping or sealing the open ends of tubular members, such as tubular support members utilized on a Bimini boat top or other boat structure. The plug has a cap from which extend upper and lower rearwardly projecting tapered planar support panels each of which includes an outwardly protruding array of ramped teeth formed integrally therewith. The height of the teeth in each array increases incrementally from a minimum height near the end of the plug remote from the cap to a maximum height adjacent to the cap. The ramping of the teeth allows for accommodational frictional engagement of the teeth with various inside dimensions of tubular support members to secure the plug tightly therewithin. A hole extends transversely through the body of the plug for receipt of a pin for pivotally securing the end of a tubular support member containing the plug to a support bracket or other members.

Abstract: A child-resistant adult-friendly prescription storage vial is presented with an over-cap which can only be removed from the vial by first orienting the cap at a particular point on the vial and then depressing a pair of push-tabs on the cap. When the cap is properly oriented the push-tabs mechanically operate a pair of locking tabs on the vial which hold the cap in place. The locking tabs are designed so that an extended lip on the tab interlocks with a slit on the cap and can only be removed from the slit when the push-tabs on the cap are manually operated.
