Definitions

  • the invention relates to a thermoplastic packaging for containing consumer goods.
  • Packaging made from thermoplastic polymers is widely used to package consumer goods, in particular consumer goods in retail outlets such as supermarkets.
  • a packaging housing providing a cavity and having a perimeter rim is filled with a consumer product and the cavity is sealed e.g. by heat-sealing a polymeric film or lid to the rim of the packaging housing.
  • the consumer can then release the consumer products by removing the polymeric lid.
  • polymeric films can be difficult to remove by a consumer because, by their very nature they are securely sealed onto the upper surface ring of the container.
  • the invention relates to a thermoplastic container for containing consumer goods, the container having a base and a surrounding side wall, the base and side wall defining a cavity, the cavity being open on its upper face, the cavity upper face being surrounded by a perimeter rim attached to the side wall, the rim comprising a primary flange which is a continuous upper surface ring with a defined width, wherein a line of weakening is provided in the rim which defines a removable portion of the rim, such that in use, the removable portion can be removed by a consumer.
  • such a container may be sealed with a polymeric film lid attached, e.g. by heat sealing to the upper surface ring to enclose the cavity.
  • a consumer can then open the pack by gripping the removable portion and breaking it off along the line of weakening.
  • the polymeric film will cover the line of weakness a consumer will also necessarily grip a portion of the polymeric film lid and be able to remove the lid conveniently and easily.
  • the container is thermoformed.
  • the line of weakening comprises perforations, although other forms of weakness such as material thinning are also possible.
  • the primary flange surface ring will provide a planar surface, however this does not need to be the case as some bends can be tolerated provided the surface is suitable for affixing a lid to the surface ring.
  • the primary flange surface ring comprises four substantially straight portions joined together by corners. Preferably the surface ring corners are rounded.
  • the side wall will be comprised of four substantially planar walls joined together by rounded corners.
  • the line of weakening preferably cuts across a corner of the rim, enabling the removable portion to be taken from a corner of the rim.
  • the width of the surface ring is preferably substantially constant. However it has been found that convenient or typical widths of upper surface rings may not be wide enough to accommodate a line of weakness with sufficient material on either side of the line of weakness.
  • the primary flange surface rim has a substantially constant width but has an increased width in the region comprising the removable portion.
  • the substantially constant width is in the range of from 2 to 8mm and the increased width has a maximum value of from 8 to 15mm.
  • the corners of the primary flange are generally curvilinear and are preferably provided by two substantially concentric circular section edges.
  • the outer edge of the four corners have substantially the same radius of curvature.
  • the corner comprising the removable portion has an inner edge having an increased radius of curvature in relation to the other three corners. This has the effect that the upper surface naturally becomes wider in the one corner comprising the removable portion.
  • the exterior profile of the container remains symmetrical at the same time. Additionally, this embodiment may be complemented to be compatible with existing handling equipment as the thickening can be implemented without altering the exterior profile of the container.
  • the rim of the container comprises a secondary flange which depends downwardly a distance defining its width, from the primary flange surface ring, the line of weakening also passing through a portion of the secondary flange, in order to facilitate removal of the removable portion of the rim.
  • the secondary flange has a substantially constant width but has a decreased width where the lines of weakness pass through the secondary flange.
  • the secondary flange has a decreased width throughout the removable portion region. It has been found that a particularly convenient arrangement is wherein the secondary flange has a substantially constant width in the range of from 3 to 7mm and the decreased width is from 1 to 3mm.
  • the container is intended to be covered with a polymeric film lid.
  • the container preferably comprises a polymeric film lid, the lid being sealed along the primary flange surface ring to close and seal the cavity, the lid covering at least a portion of the line of weakening.
  • Figure 1 is a perspective view of a container according to the present invention.
  • Figure 2 is a plan view of a container according to the present invention.
  • Figure 3 is a side view of a container according to the present invention.
  • Figure 4 is a front view of a container according to the present invention.
  • figure 1 shows a thermoplastic thermoformed container 10 comprising a lower base 12 and side walls 14, 16, 18, 20, providing an open cavity 22.
  • a rim 24 which runs around the perimeter of the container.
  • the rim 24 comprises a primary flange 26 which is a flat upper facing ring surface. This acts to provide a flat surface onto which a polymeric film can be attached e.g. by heat-sealing, to seal the cavity.
  • the primary flange 26 can be seen to be made up of four straight portions 28, 30, 32, 34 and four rounded corners 36, 38, 40, 42. Also provided is a line of perforation 44 which cuts across the rim 24 to provide a removable portion 46.
  • the primary flange 26 has a constant width along straight portions 28, 30, 32 and 34 which is approximately 5mm.
  • the width of the primary flange 26 also remains constant in corners 36, 38 and 40 although it is slightly wider at 6mm. However the width of the primary flange 26 in corner 42 is increased significantly relative the rest of the surface width having a maximum value of 12mm.
  • corners 36, 38, 40 and 42 all have the same circular section exterior edge with a radius of curvature of 28mm. Corners 36, 38 and 40 have their internal edge provided by the same circular section edge with a radius of curvature of 25mm. However the inside edge of corner 42 is provided by a circular section of radius of curvature of 40mm. This has the effect of thickening the width of the upper surface ring at corner 42.
  • the increased width at corner 42 ensures that there is sufficient material on the primary flange 24 either side of the perforation 44.
  • a secondary flange 50 which depends downwards from primary flange 26.
  • the secondary flange 50 runs all the way around the primary flange 26 and provides strength to the rim 24.
  • the width of the flange is 5mm all the way around except for in the region of corner 42. In this region the secondary flange 50 reduces in width gradually to 2mm.
  • a polymeric film is sealed, e.g. by heat sealing onto the primary flange upper surface 26.
  • the polymeric film covers the portion of the perforation 44 that is present on the primary flange 26.
  • the contents of the package are preferably a food product such as heatable food product.
