Definitions

  • closures which employ in combination therewith a locking or safety ring designed to be ruptured when the closure is removed from the container.
  • a tamper-proof closure device is described in German patent specification 619,169 which is constructed of sheet metal and comprises a top cup joined to an underpart by connecting elements.
  • metal screw caps cannot always be used for containers holding corrosive chemicals and, of course, such as tamper-proof closure is therefore not universally suitable for chemical purposes.
  • closure comprises a combination of two parts: a screw cap and a locking or safety ring (see, for example, US. Patent 2,950,832).
  • Still another type of tamper-proof closure as disclosed in U.S. Patent 2,124,638 comprises, in combination with a screw cap, a one-piece locking ring which breaks when the cap is unscrewed and the container is Opened.
  • the locking ring which must consist of breakable material does not break in a predetermined and accurate pattern.
  • the locking ring often remains wedged between the container neck and cap thereon and it is not always apparent when the cap has been unscrewed slightly and the ring has been broken.
  • an original screw closure for containers having a threaded neck, a centering edge disposed below the threaded portion of the neck, and a collar of a diameter greater than that of the centering edge disposed thereabove.
  • the collar is provided with one or more recesses or grooves therein, designed to receive in locking engagement the lugs formed on the locking ring.
  • the closure member or cap proper comprises an internally threaded screw cap having a depending skirt of a diameter greater than the inside threaded portion thereof and the inner face of the skirt is provided with one or more teeth which extend inwardly and at an angle oblique to the inside surface in a direction generally opposite to the direction in which the cap is rotated to screw it onto the container.
  • a locking ring comprising an outer ring and an inner ring interconnected by rupturable webs, the outer ring being dimensioned to fit snugly around the collar of the container and having one or more inwardly directed lugs which can be located within the recesses or grooves in the collar to provide a locking system which will prevent rotation of the outer ring while permitting axial movement thereof.
  • the inner ring segment of the locking ring is dimensioned to fit around the centering edge and is provided on its outer surface with a plurality of teeth extending obliquely outwardly in a direction generally similar to that in which the cap is rotated when it is screwed onto the container.
  • the teeth on the screw cap are adapted to slide over the teeth on the locking ring when the locking ring is positioned on and about the centering edge and collar of the container and the screw cap is screwed onto the neck, and further these teeth are also adapted to engage with each other to provide another locking system.
  • the outer ring is provided with more than one lug, preferably with 2 or 4 lugs which fit into the same number of recesses in the collar of the container.
  • the threaded screw cap and safety ring may be conveniently constructed of synthetic resinous materials which can be easily and economically molded.
  • resinous materials which can be easily and economically molded.
  • thermoplastic materials such as, for example, polyethylenes (low and high pressure) having a density of at least 0.95; polypropylenes, polyamides and polystyrenes.
  • thermoplastic synthetic resins resistant to the attack of the more corrosive chemicals may be employed, it is preferable to use thermoplastic synthetic resins resistant to the attack of the more corrosive chemicals.
  • the screw cap and safety ring may be constructed of the same or difierent materials.
  • the safety ring should consist of a thermoplastic material
  • the cap may consist either of thermoplastic or of duroplastic material (pressed artificial material) such as melamine resins, urea resins or phenol plastics.
  • thermoplastic material such as polyethylene
  • thermosetting resins such as urea and phenol formaldehyde
  • a further advantage of the closure herein resides in the particular design which makes it very difficult or even impossible to reassemble the same.
  • the deformable thermoplastics used in the containers of this closure such as polyethylene, for example, cannot be easily glued or joined together. Only with great difficulties, at best, can these thermoplastic materials be rewelded. Specialized equipment would be required to reweld the present closure, and such an operation would require precision since the segments of the upper ring are connected at only point contacts to the lower ring.
  • the upper ring can consist of two halves or may as well be designed to form several (for example four or six) segments when ruptured.
  • thermoplastic closure it is extremely difficult to remove the thermoplastic closure from the container neck with hot air or hot water in such a way that the locking ring will not fall apart since the areas of point contact between the web tend to be easily weakened at elevated temperatures, Whereas many of the previously proposed tamper-proof closure can be opened under the influence of heat without the permanent destruction of any portion thereof because the lower portion of the screw cap along its entire circumference and the closure thus can be pulled off under the effect of heat.
  • FIGURE 1 is a side elevation of the upper portion of a bottle to be used in conjunction with the improved closure of the present invention
  • FIGURE 2 is a plan view of the top of the bottle shown in FIGURE 1, illustrating particularly the structure of the flanged portions thereof;
  • FIGURE 3 is an axial section of the improved screw cap of the present invention which is adapted for use on the bottle shown in FIGURES 1 and 2;
  • FIGURE 4 is an inverted plan view of the screw cap shown in FIGURE 3, illustrating with particularity the orientation of the teeth projecting from the inner face thereof;
  • FIGURE 5 is a plan view of a locking ring adapted for use in conjunction with the screw cap shown in FIG- URES 3 and 4 and depicting one form of rupturable web which can be used to join the inner and outer surfaces thereof;
  • FIGURE 6 is an axial section of the locking ring shown in FIGURE 5;
  • FIGURE 7 is a view similar to FIGURE 1 showing the screw cap locking ring in section, located on the neck of the bottle.
  • FIGURES 1 and 2 there is shown the neck of a bottle 2 comprising a screw-threaded portion 1, a centering edge 3, and an outwardly projecting collar 4 which is provided with diametrically opposed vertical grooves 5 (see particularly FIGURE 2).
  • a screw cap shown generally at 6 (FIGURES 3 and 4) is adapted to be received in threaded engagement with the neck of the bottle 2; the cap 6 is provided with an internal screw thread 7 and a depending skirt 8 of larger diameter than the screw-threaded portion.
  • the skirt 8 is provided with teeth 0 which extend obliquely from the interior wall thereof in a direction (see FIGURE 4) generally opposite to the direction in which the cap is rotated when it is screwed onto the bottle. The inclination of these teeth 9 can clearly be seen from FIGURE 4 illustrating the closure from below.
  • the cap 6 is associated in use with a locking ring 10 (FIGURES 5 and 6) which comprises an outer ring 11 connected by webs 16 or the like to two inner ring portions 13 and 14.
  • the outer ring is provided with two 4- diametrically opposed, inwardly directed lugs 12 and the two inner ring portions 13 and 14 are each provided with teeth 15 which extend in a direction generally similar to the direction in which the cap is rotated when it is screwed onto the bottle.
  • the web 16 be formed to connect in point contact with the outer ring 11 thereby positioning the weakest structural portion of the web at the point where it unites with the outer ring. It is preferred in this embodiment, that the neck make point contact at the surface of the outer ring. It is important that the enscrewed, rupture occurs in a predetermined manner at the surface of the outer ring. It is important that the entire web break away from the outer ring at its surface in order that the same will be entirely free and disconnected from the web and hence slide unimpeded down the contain-er neck.
  • the area and type of point contact between these segments of the locking ring be such as to be readily capable of being severed.
  • the total of point contact area between the web and the outer ring be about 0.1 to 0.4 mm. preferably about 0.2 to 0.3 mrn. based on a cap diameter of 1 cm.
  • Another way of expressing the binding eifect between the web and outer ring is in the ratio of the area of point contact to the diameter of the ring.
  • the greater the diameter of the cap the greater mechanical advantage is provided in turning the cap and a greater area of point contact can be provided, when using larger diameter caps.
  • the total point contact area for a cap having a diameter of one centimeter is in the range of about 0.1 to 0.4 square millimeter, a cap having a larger diameter can have a disproportionately higher point contact area.
  • the ring 10 is first placed in the top of the container, particularly over the neck, so that the inner ring portions 13 and 14 girdle the centering edge 3 and the lugs 12 are located within the grooves 5 of the collar 4.
  • the cap 6 is then screwed onto the neck, the inwardly directed teeth 9 of the skirt 8 sliding over the outwardly directed teeth 15 of the ring portions 13 and 14 until the cap is screwed tight.
  • the closure according to the invention therefore, gives an indication not only that a closed container has been fully opened, but also that an attempt has been made to open it.
  • Another advantage of the closure according to the invention is that the ring 10 and cap 6 can be made of thermoplastics which are not seriously affected by normal impacts and which can Withstand corrosive chemicals, while the containers to be closed can be made of glass or plastics.
  • the closure according to the invention can therefore be used to close glass containers containing corrosive chemicals in such a way that any opening or attempt at opening is immediately and visually apparent.
  • a tamper-proof closure comprising a closure cap and a safety ring having a first and second section adapted to fit onto the neck of the container, said first section composed of a plurality of upper disconnected ring members adapted to be positioned between the cap and the container neck and each of which is connected to the second section by a plurality of rupturable webs.
  • a container having a threaded neck and a screw closure for use therewith said container having a centering edge disposed below the threaded portion of the neck, and a collar of greater diameter than the centering edge disposed therebelow, the collar being provided with at least one recess therein
  • said closure comprising an internally threaded screw cap having a depending skirt of larger diameter than the threaded portion thereof, the skirt being provided on the inner surface thereof with a plurality of teeth which extend obliquely inwardly in a direction generally opposite to the direction in which the cap is rotated to screw it onto the container, and a locking ring comprising an outer ring and an inner ring interconnected by a plurality of rupturable webs, the area of contact of each of said webs with the outer ring being smaller than the area of contact between said webs and the inner ring, the outer ring being dimensioned to fit around the collar of the container and having at least one inwardly directed lug which can be positioned within said recess in the
  • a locking ring for use in a tamper-proof closure comprising a first ring and a smaller second ring, said first ring having on the inside periphery thereof at least one inwardly directed lug, said second ring having a diameter smaller than the first ring and having a plurality of teeth extending obliquely outwardly, a plurality of rupturable webs joined between and connecting said first and second rings, the area of contact of each of said webs with the first ring being smaller than the area of contact between each of said webs and the second ring.
  • each of said webs is attached by a point contact with the first ring.
  • a tamper-proof closure comprising an internally threaded screw cap having a depending skirt below the threaded portion, the skirt being provided on the inner surface thereof with a plurality of teeth which extend obliquely inwardly, and. a locking ring comprising, a first ring and a smaller second ring, said first ring having on the inside peri hery thereof at least one inwardly directed lug, said second ring having a smaller diameter than the first ring and having a plurality of teeth extending obliquely outwardly, a plurality of rupturable webs joined between and connecting said first and second rings, the area of contact of each of said webs with the first ring being smaller than the area of contact between said webs and the second ring.
