Definitions

  • ABSTRACT This invention concerns improvements in a plastic closure for a tight-head container having a protruding lip opening and adapted to hold a liquid under pressure
  • the closure includes a base, a generally cylindrically-shaped inner section or skirt adapted to fit into the container opening and a generally cylindrical- Iy-shaped outer rim section or skirt havingan annular flexible support lip adapted to enclose the outer surface of the container opening and to engage the protruding lip of the container.
  • the improvements include (l) a circumferential strengthening collar disposed on the outer portion of the outer rim section in the s gn f .thedmemmite K159195 2?
  • the present invention is concerned with improvements in a plastic closure for a tight-head container having a protruding lip opening and adapted to hold a liquid under pressure
  • the closure includes a base, a generally cylindrically-shaped inner section adapted to fit into the container opening and a generally cylindrically-shaped outer rim section having an annular, flexible support-lid adapted to enclose the outer surface of the container opening and to. engage the protruding lip of the container, wherein the improvements include the provision of a circumferential strengthening collar disposed on the outer portion of the outer rim section in the region of the rim opposite the closure base.
  • FIG. 4 is a side view of a particularly preferred embodiment of a closure cap of the present invention with the left half cut away in cross section;
  • FIG. 6 is a cross-sectional view of the embodiment of the present invention shown in FIG. 4, including a showing on the left of the closure cap during the process of pressing it into a bottles neck and on the right, the completed insertion into the containers neck.
  • the closure cap shown in FIGS. 1-3 is bowl shaped. It has a circular cap base 1, from which projects in an outward axial direction an annular, cylindrical rim or skirt section 2 and radially spaced to the inside thereof, an annular cylindrical inner section or skirt 3.
  • the rim section 2 includes in the area of its open end an annular resiliently yielding support lip or projection 4, protruding radially to the inside, as the drawings show, to form an apex A.
  • rim section 2 is reinforced by an annular, circumferential ring-shaped collar 10, as well as by equally spaced ribs 11 extending from the caps base.
  • Inner section 3 forming a support lip has a barrelshaped convexly curved outer contour 5.
  • the apex B of inner section 3 is disposed at a point closer to the caps base 1 than is the location of apex A of support lip 4.
  • the apex B is designed to seal tightly the inner wall 17 of the containers neck 15.
  • the diameter of apex B is greater than the diameter of the inner wall 17 of the containers neck 15.
  • the inner section 3 is designed in the form of a hollow cylinder to provide flexibility.
  • the wall between the hollow cylinder of the inner contour, and the convex outer contour is relatively strong and capable of exerting considerable sealing force or pressure.
  • the closure cap is shown in an intermediate position while being pressed into the containers neck 15. Due to the axial disposition of apex A, of support lip 4, and apex B of thesupport lip 3, the encircling apex A first contacts the rounded outer contour-of the protruding lip 16 of the containers neck 15. Thereafter, apex B of the support lip 3 contacts the hollow cylinder of the interior wall 17 of the containers neck 15. During the process of insertion, the support lip 4 and rim section 2 are radially spread outward, which results in an inwardly-directed pressure by apex A on the rounded outer contour of the protruding lip 16 of the containers neck 15. This radially, inwardly directed force opposes the outwardly directed force of apex B of sealing lip 3, which has been created by the force which sealing lip 3 exercises du to its particular construction.
  • closure cap in a completely compressed condition fits with great radial stress against the interior wall 17 of the containers neck, which insures a reliable seal even at high pressure, as could occur during pasteurizing of the containers contents once it has been sealed.
  • FIGS. 46 A particularly preferred embodiment of the present invention is shown in FIGS. 46, with elements similar to those shown in the embodiment in FIG. 1 being given similar numbers in the series or letters with primes associated therewith.
  • the major differences between the embodiment shown in FIGS. 46 as compared with the embodiment shown in FIGS. l-3 are as follows.
  • the closure cap of FIGS. 4-6 does not include elements corresponding to ribs 11, ring 9 or vents 8. Also, the inner, lower surface of rim section 102 is tapered outwardly from top to bottom to form a pointed rim 112. Further, the concave upper surface 106 of base 1010 extends from the periphery thereof rather than being disposed only in the central portion of the base as in the embodiment shown in FIGS. 1-3.
  • closure caps of the present invention are preferably constructed of a tough, resilient, flexible plastic such as polyethylene.
  • a tough, resilient, flexible plastic such as polyethylene.
  • other plastics haiving these properties such as polypropylene, etc., also may be utilized to advantage in the present invention.
  • the collar which assists in resisting the force exerted by the cylindrical, inner section or skirt substantially reduces the possibilities of bottle breakage on capping as well as the popping out of the cap as a result of internal pressure.
  • the bottom edge of the collar also provides a means whereby the closure caps of thepresent invention may be conveniently opened with conventional bottle openers.
  • bottles capped with the closure caps of the present invention can only practically be opened with bottle openers and when this is done, the opener leaves indentations or other marks indicating that the bottle has been initially opened, even after it has been resealed with the original cap.
  • the concave shaped base of the closure caps of the present invention provides greater strength.
  • FIGS. 46 which includes the pointed rim 112 has the advantage that this pointed rim is more readily deformed in opening with a bottle opener than the embodiment of FIGS. 1-3.
  • the pointed rim discourages people from trying to open the bottle by hand thus requiring people to use a bottle opener which in turn will produce the tell-tale marks indicating that the bottle had been previously opened.
  • a generally cylindrically-shaped hollow inner section adapted to fit into the container opening and having a diameter larger than the diameter of said container opening, the outer surface of said inner section being convex in contour, and
  • outer rim section having an annular, flexible support lip adapted to enclose the outer surface of the container opening and to engage the protruding lip of the container, said outer rim section having a circumferential collar disposed on the outer portion thereof in the region of the rim opposite said base, the apex of the convex contour of said inner section being dis posed at a point closer to said base than the location of the support lip of the outer rim section,
  • the closure and collar thereof being constructed of a flexible, resilient plastic and said outer rim section being tapered outwardly in the region of said collar to form a pointed edge at its end opposite said base whereby said pointed rim discourages people from trying to remove by hand said closure from said container and whereby removal of said closure from said container by means of a bottle opener leaves indentations indicating that said container has been opened.
