Abstract: A childproof closure for bottles in general with easier operation and improved safety, including a hood, which can be rigidly coupled to a metal cap which can be screwed onto the neck of a bottle and the like, and an outer cap, which can be superimposed on the metal cap and the hood. Axial protrusions are provided on the base of the hood which can be detachably coupled to inner teeth formed by the outer cap. Elastic means are furthermore provided for axially spacing the bottom of the outer cap and the base of the hood and are suitable to allow the engagement of the axial protrusions and of the inner teeth in order to rigidly rotationally couple the outer cap and the hood when axial compression is applied to the outer cap.

Abstract: A container end is provided so that upon opening, a generally triangular vent region is formed with an apex pointing rearwardly toward the head space to vent the container, e.g. during pouring. A container is provided that achieves a fast and smooth pour with a relatively small increase (relative to certain previous configurations) in the opening area and achieves a superior pour without increased bursting, buckling or opening failures associated with relatively larger openings.

Abstract: A hot fillable plastic container having a body with a neck surrounding a dispensing aperture, the neck having an inner wall and an outer wall spaced therefrom to thereby provide a gap between the inner wall and outer wall which functions as a thermal insulation means. The neck is thus able to better withstand the temperatures encountered during the filling operation without deformation.

Abstract: A closure is provided for use with a drink container wherein the closure includes an inner member, having an opening formed therein for receiving a straw and having a peripheral portion for mounting to the drink container, and an outer member configured to be fitted to the inner member forming a compartment therebetween. The outer member also has an opening, with the opening of the outer member aligned with the opening of the inner member while the outer member is fitted to the inner member. The aligned openings permit penetration of a straw therethrough. The inner member is shaped to prevent any beverage from within the drink container from entering the compartment even while a straw penetrates the aligned openings of the inner and outer members.

Abstract: A container comprising a main portion (1) with variable capacity and a cover (2) which may be coupled in dovetail manner, with a leak-tight sealing and with no possibility of disassembly, the cover embodying a filling window (16) which may be shut by a rotatory disk (9) which in turn is provided with two diametrically opposite windows (17) and (19), the first of which faces the window (16) during the container-filling phases and is located diametrically opposite during the temporary-sealing phases, implementing a hermetic sealing; while in the second window there is located a blocking button (22) which, after the final filling of the container, is capable of being moved inside, immovably blocking the shutter disk (9) at the cover (8) and implementing the final, non-workable sealing of the window (16) of said cover.

Abstract: An aperture forming structure, which when attached to or integrally formed in dispenser packages for flowable substances allows reclosure and single or multiple uses. The aperture forming structure includes a break away tip member of thermoformable plastic. The break away tip includes a hollow protrusion from a surface. The intersection of the hollow protrusion and the surface is a fault line. Rupturing of the fault line creates an aperture from which the contents of the dispenser package may exit. A cap may be integrally formed with the aperture forming structure and detached for protecting the hollow protrusion or for closing the aperture created when the fault line is ruptured. The aperture forming structure can be made by heating a relatively stiff substantially flat thermoformable sheet of and then stretching the sheet to create a first and a second hollow protrusion in a tiered configuration. A rupture line is placed at the intersection of the first and the second protrusions.

Abstract: A beverage container lid is disclosed and taught whereby the brim of the lid is provided a multiplicity of small inwardly directed, radial protuberances projecting inward from the lid's outer peripheral brim which snap-in place under the cup's beaded rim thereby securing the lid to the cup's rim. In addition the circumferential array of small protuberances is interrupted by one or more, preferably three, inwardly projecting, circumferentially elongated oblong protuberances which engage the under surface of the cup's circumferential beaded rim. A second embodiment the beaded rim of the beverage cup is also taught wherein circumferentially spaced depressions, or recesses, corresponding to the oblong protuberances of the lid are provided. When the lid is applied to the cup, the oblong protuberances are indexed so as to pass over the rim depressions.

Abstract: A cut and pierce closure molded from a rigid plastic material for a container whose open mouth is normally sealed by a thin membrane applied to a rim of the container. The closure is removably applied to the container in a closing orientation by interengaging helical threads on the exterior of a neck of the container and an annular skirt of the closure. To dispense the contents of the container, the closure is removed and reapplied in an inverted orientation, a flange extension of the closure skirt surrounding the rim of the container and serving to center the closure in its inverted orientation on the container. A top panel of the closure is provided with a double-ended arcuate shoulder that engages the membrane when the closure is in its inverted orientation on the container to maintain tension in the portion of the membrane in engagement with the shoulder. The arcuate shoulder also serves, in combination with the flange extension, to trap the rim of the container therebetween.

Abstract: A stop motion hinge for use on garbage cans utilizes a spring loaded hinge for stop motion of the lid. A spring loaded washer or plate with a series of bumps abuts the sides of the hinge. The sides of the hinge member have a series of apertures to allow the bumps to protrude through. The base member in connection with the hinge also has a series of apertures corresponding to the bumps so that as the hinge is moved, the pressure of the washer will force the bumps to lock into the set of apertures so that the hinge will form a fixed connection with base member when the lid is raised. The hinge is used on garbage cans in connection with the lid so that a lid with stop motion function is created. The hinge is preferably attached by a pop rivet to make installation easy.

Abstract: The child-resistant package (100) can be readily opened by an adult with a one-hand operation. The pushtab (123, 123'), which together with the interlocking tooth (119) form the child-resistant feature of the package, is placed on the closure (120). Therefore, an adult user may easily depress said pushtab and at the same time disengage said closure to open said package by using only one hand for both operations.

Abstract: A resealable can end is provided including a neck member and hat member which can be sealed onto and removed from the neck member of the end, and is capable of containing product under pressure if desired. This end can be added, as by a conventional seam, to a metal container body to obtain resealing containment of partial contents retained in the container, and to provide an improved mouth construction (or pour opening) for better pouring and for comfortable direct drinking from the container. Also disclosed are improved methods of and apparatus for making such a resealable hat and neck type of container end.

Abstract: A cap for a blood-sampling tube has a collar adapted to fit on the tube and a tubular extension extending from the cap, defining an axis and having an outer end remote from the cap. An annular wall is formed inside the cap spaced from the outer end and an annular lip projects axially backward from the outer end and has an outer surface spaced radially inward of an inner surface of the extension and an axially directed inner end. A pierceable flat membrane in the extension on the annular wall snugly engages the inner surface of the extension and has an outer face spaced axially from the inner end of the lip. The lip has an inner surface defining a cylindrical passage of a predetermined diameter and the wall has an inner edge defining a similarly dimensioned coaxial annular passage.

Abstract: The air vent has a body with a central axis, a top end, a bottom end, a flat surface on the top end and a flat surface on the bottom end. A gripping surface extends from the top flat surface to a stop surface that is transverse to the axis. The small diameter end of an upper conical surface joins the stop surface. A large diameter end of a lower conical surface joins the large diameter end of the upper conical surface. A cutting edge formed by the flat bottom surface and the lower conical surface pierces a container when the air vent is forced into the container. The lower conical surface expands the opening made by the cutting edge. The stop surface limits penetration and the upper conical surface urges the container wall toward the stop surface. An air vent passage through the top flat surface and the bottom flat surface lets air into the container. A cap closes the air vent passage. The air vent is removed from an empty container for use in another container.

Abstract: The neck of a container has a smooth seal surface engaged by the inner skirt or plug of a cap. Such surface is free of trim and parting line flaws which are characteristic of blow-molded jars because the surface is formed in such a way that the seal surface is not in contact with mold parting lines and further the trim (excess plastic) of the neck is located away from the sealing surface. In one form of the disclosure, above the sealing surface the neck wall slants outward and then bends upward-inward in a short, tapered stretch about 18.degree. to the horizontal which engages the underside of the cap disk to compress against the disk or a liner or foil. Other forms of seal surfaces are disclosed. The exterior of the neck is formed with shoulders which engage over locking beads on the interior of the outer skirt of the cap. Caps suitable for combination with the neck, methods of forming the neck and mold apparatus for forming the neck are also disclosed.

Abstract: A tamper resistant bottle cap and neck for a threaded blow molded bottles which hold liquid, such as milk. The bottle cap and neck combination has an enhanced tamper evidency feature wherein a circumferential lip is formed at the outside edge of the interface between the cap and the neck. The lip protects the contents of the bottle by limiting the ability of potential tamperers to pry or bend upwardly the rachet ring at lower edge of the cap.

Abstract: A thin-walled, wide mouth molded plastic container is provided with a tamper evident band initially molded as a straight-walled cylinder spaced outwardly of the lip of the container and connected thereto by a frangible horizontal bridge. The upper edge of the cylindrical band extends above the level of the container lip. Subsequent to molding and preferably before capping, the band is curled inward by application of a curling tool. The container lid is axially applied, the outer edge of the lid displacing the curled band outward. The resilience of the band and bridge permits outward deflection and immediate restoration of the curl to its initial position. The curl prevents removal of the lid without fracture of the bridge and removal of the tamper-evident band.
