Definitions

  • This invention relates to pourers for containers, in particular for cartons of paperboard containing milk, fruit and the like.
  • Such pourers are typically a two-part closure comprising a spout attached to the carton and a cap which is screwed onto the spout, the carton being opened by unscrewing the cap from the spout.
  • a one-piece pourer for a container comprising a spout portion one end of which is adapted to be secured to, in communication with the interior of, the container, and a cap portion integrally moulded with the spout portion, characterised in that the cap portion is interconnected with the other end of the spout portion by a line of weakness, and pull means being integrally moulded with the cap portion whereby, on pulling on the pull means to tear the line of weakness, the cap portion is separated from the spout portion to open the pourer.
  • the cap portion is a sealing fit on the other end of the spout portion, it being preferred that the cap portion is a push sealing fit on the spout portion, .although a threaded connection may be provided.
  • the other end extent of the spout portion has a circumferential bead formed therearound, and the free end extent of the cap portion has a corresponding circumferential bead formed internally thereof, the cap portion being a push snap-fit on the spout portion with the beads co-operating to retain the cap portion sealingly on the spout portion.
  • the pull means comprise an annular ring-pull positioned to overlie the end face of the cap portion and interconnected with the end face of the cap portion over a small portion of the circumference thereof, for example of the order of 55°.
  • the one end of the spout may include an increased diameter flange portion therearound for welding or gluing to the inside face of the container to attach the pourer to the container with the spout portion thereof projecting through a corresponding aperture in the container .
  • the pourer is moulded from a low density polyethylene .
  • Figs . 1 and 2 are a side view and a rear view respectively of a pourer according to the invention
  • Fig. 3 is a section on the line III - III of Fig. 2 to a larger scale
  • Figs . 4 and 5 are a side view and a rear view respectively of the pourer of Figs. 1 and 3 with the cap portion sealingly positioned on the spout portion subsequent to tearing of the line of weakness, and
  • Fig. 6 is a section on the line IV - IV of Fig. 5 to a larger scale. DESCRIPTION OF THE PREFERRED EMBODIMENT
  • a one- piece, integrally moulded pourer for location on a polyethylene coated paperboard carton, the pourer comprising a hollow, generally cylindrical spout portion 2 of circular cross-section around one end of which is provided an increased-diameter, annular flange 4 for reasons which will become apparent .
  • a circumferential bead 6 surrounds the external surface of the other end of the spout portion 2 to define a shoulder 8 on said surface.
  • the pourer further includes a cap portion indicated generally at 10 and including a top wall 12 and a depending, generally cylindrical sidewall 14 of circular cross-section.
  • a bead 16 is formed internally around the free end of the sidewall 14.
  • the extremities of the bead 6 on the spout portion 2 and the bead 16 on the cap portion are interconnected with one another by a thin circumferential membrane which integrates the spout portion 2 and the cap portion 10 and which constitutes a line of weakness 18 therebetween .
  • the pourer is completed by an annular ring-pull 20 which is integrally moulded with the cap portion 10 and overlies the top wall 12 of the cap portion 10. More particularly, the ring-pull is of external diameter just less than that of the cap portion 10 and is connected to the top wall 12 of the cap portion 10 by means of a neck 22 extending around a small part only of the pourer, typically about 55° thereof.
  • This figure can of course vary providing there is secure attachment between the ring-pull 20 and the cap portion 10 capable of withstanding the forces to be applied thereto as will be detailed below.
  • the described pourer which is preferably moulded from a low density polyethylene, is, in use, located in a corresponding aperture in the wall of an associated container with the upper surface of the annular flange 4 ultrasonically welded, glued or otherwise secured to the inner surface of the container bounding the aperture therein to seal said aperture, the pourer projecting from the container.
  • the intact nature of the line of weakness 18 between the spout portion 2 and the cap portion 10 is an immediate visual indication that there has been no tampering with, or unauthorised use of, the container.
  • a user pulls on the ring-pull 20, the applied force being transmitted through the neck 22 to the cap portion 10 and thence to the line of weakness 18.
  • the contents of the container can be dispensed as required through the now-open spout portion 2.
  • the pourer can be re-closed by fitting the cap portion 10 on and over the spout portion 2. More particularly, and referring to Figs. 4 to 6, the internal bead 16 on the cap portion 10 is dimensioned to be a push snap-fit over the bead 6 on the spout portion to underlie the shoulder 8 on the spout portion and to effect a sealing closure of the pourer with the internal surface of the top wall 12 of the cap portion 10 sealing against the free end of the spout portion 2. Re-opening of the container is achieved by again pulling on the ring-pull 20 to disengage the bead 16 on the cap portion 10 from the shoulder 8 and to remove the cap portion 10 from the spout portion 2.
  • a pourer for a container which comprises an integral, one-piece moulding capable of economic manufacture and ready opening without the necessity to dispose of any tear band or the like subsequent to opening.
  • the precise construction of the pourer may differ from that illustrated without departing from the scope of the invention.
  • the pull means on the cap portion 10 may be other than a ring-pull 20, providing leverage to tear the line of weakness can be achieved, while re-location of the cap portion 10 on the spout portion 2 may be achieved other than by a snap push-fit, for example a screw-threaded connection.

Abstract

La présente invention concerne un verseur pour contenant, en particulier une boîte de carton contenant une boisson. Ce verseur est intégralement moulé sous la forme d'une seule pièce et il comprend une partie bec (2) dont l'une des extrémités est adaptée pour être fixée au contenant, en communication avec l'intérieur de celui-ci, et une partie bouchon (10) intégralement moulée avec la partie bec (2) et interconnectée avec l'autre extrémité de la partie bec (2) par une ligne de faiblesse (18), une tirette étant intégralement moulée avec la partie bouchon (10). En tirant cette tirette (20) de façon à déchirer la ligne de faiblesse (18), on sépare la partie bouchon (10) de la partie bec (2) et l'on ouvre le verseur.
