Definitions

  • This invention relates to a container and plastics closure therefor.
  • Screw-threaded engagement of the closure and the container is well known and it is also known to provide, on the inside of the closure, a plug which co-operates with the mouth portion of the container to form a seal when the closure is screwed home.
  • a conventional closure positioning machine for fixing a closure with its security band onto a filled container will have a rotating head which screws the closure home in the normal manner. It is, however, possible, dependent upon the material of which the closure is made and the dimensions and construction of the closure and container, to assemble a closure on a filled container by a simple axial relative motion between the two whereby the screw threads are overridden.
  • the closure positioning machine is thereby of more simple construction without any necessity of having to provide a rotary motion to the closure holding head.
  • the disadvantage of this has been that the closure cannot be relied upon to exert top pressure on the sealing medium as its final position of thread engagement is random.
  • a container and closure therefor at least the latter being of plastics, the neck portion of the container having external screw-threads for engagement with internal screw-threads on the skirt of the closure, in which the closure is capable of being applied to the container by an axial relative movement of the closure and container to override the interference of the threads, wherein the closure is provided with a plug extending from the inside surface of the base of the closure and capable of entering and forming a seal with the mouth portion of the container over the required range of axial position and wherein the closure is provided with an integral annular security band joined by tearable webs to the free end of the closure skirt, in the assembled condition of the container and closure the band being capable of lying with variable axial clearance from annularly disposed nibs and a security band separating bead on the container.
  • the plug makes sealing contact with an inwardly porjecting annular shoulder inside the mouth of the container over an adequate axial range.
  • the plug is provided with an external annular bead which makes sealing contact with a straight sided mouth of the container over an adequate axial range.
  • the nibs on the container engage with castellations on the security band when the closure is unscrewed to tear the webs and release the closure from the security band.
  • the nibs and/or the castellations may be provided with edges which are presented radially to the cooperating nibs and castellations on unscrewing the closure to assist in engagement.
  • all the nib engagement surfaces may be disposed radial to the bottle neck.
  • the nibs may be shaped so as to enable the half-moulds used to form the container to be withdrawn.
  • a container and closure therefor in accordance with the invention are both made of any suitable plastics, for example low density polythese which is preferred or high density polythene or even polypropylene so long as the material used together with the dimensions of the container and closure particularly in relation to the screw-threads therefor enable axial relative movement between the two to position the closure on the container.
  • suitable plastics for example low density polythese which is preferred or high density polythene or even polypropylene
  • the closure may be knurled or serrated at 3 to enable a good grip to be obtained when unscrewing the closure or repositioning the closure after it has been removed.
  • the closure has a base 4 and a skirt 5 at the free end of the skirt there being provided an integral security band 6 attached to the skirt 5 by tearable webs 7 (see particularly Figure 7).
  • a plug 8 Projecting inwardly from the base 4 of the closure is a plug 8 which may have a rounded end at 9. Projecting from the inner wall of skirt 5 are internal screw-threads 10. In this particular embodiment a six start thread has been provided and preferably the thread is multistart.
  • the security band 6 has inwardly directed radial castellations 11 which can be seen particularly in Figures 7 and 8.
  • the container which is more particularly illustrated in Figures 3 to 6 has external screw-threads 12 for co-operation with the screw-threads of the closure.
  • the mouth portion of the container is provided with an inwardly projecting annular bead 13 to form a line contact seal with the closure plug 8.
  • the extremity 14 of the mouth of the container may be in the form of a pouring lip or not as desired.
  • a security band On the outside of the container neck portion are a security band separating bead 24 and a series of outstanding nibs 15 with a radial surface 16.
  • Each nib also has an angled surface 17, either from the lower axial edge or the circumferential edge, in the latter case at an angle to suit half mould opening dependent on the position of the nib.
  • the two halves of the mould on forming the container will be moved away from each other in the directions of arrows 18 as illustrated in Figure 6.
  • a closure and container constructed in accordance with the present invention enables the closure to be positioned on a filled container by a simple axial movement of the closure towards the container.
  • the closure holding head of the machine may be free to rotate about the axis of the closure dependent upon.the interference which is encountered as the two sets of threads override one another.
  • the plug 8 makes a good sealing contact with the annular bead 13 of the container and because of the cylindrical nature of the plug 8 the seal will be effective regardless of the final position of the closure on the container. This final position will, of course, be dependent upon the interaction of the screw-threads and the orientation of the closure in relation to the container. Such orientation with automatic closure positioning equipment will be random.
  • closure may come to rest in a position as illustrated in Figure 1 in which the closure is in the screwed fully home position although this position has been achieved not by screwing but by axial placement.
  • closure may assume a position as illustrated in Figure 2 where the closure is far from being in the screwed fully home position but nevertheless an effective seal is achieved by virtue of the cylindrical plug 8 contacting the annular bead 13.
  • the outer surface of the plug 8 may have a draft in the order of 1 ⁇ 2 ⁇ .
  • a closure 19 made of plastics ( Figures 9 and 10) is for sealing a container 20 ( Figure 11) of glass although even in this embodiment the container 20 may be of plastics.
  • the closure 19 has a plug 21 with an external annular bead 22 which makes sealing contact with the straight sided mouth portion 23 of the container 20 over the desired axial range of positions.
  • An added advantage of-the construction of the present invention is that because only relative axial movement between the closure and container takes place on positioning of the closure, the tearable webs 7 are subjected only to compression and no circumferential shear so that there is no likelihood of them becoming broken at this stage. They can thus be made dimensionally smaller so as readily to rupture when subject to circumferential shear and tension on removal of the closure from the container.
