  • Relative terms such as “horizontal”, “vertical”, “inward”, “downward”, “outward”, “upward”, and derivatives thereof, or any other terms related to direction or orientation should be construed to refer to the orientation as then described or as shown in the drawing(s) under discussion. These relative terms are for convenience of description only and do not require that the invention be constructed or operated in a particular orientation.
  • side wall 14 has an upper part 20 and a lower part 22.
  • the upper part 20 and the lower part 22 may be separated by a line of weakness 23.
  • the upper part 20 extends upward and curves inward relative to the container 12.
  • a flange 24 extends inward from an inner face 26 of the side wall 14.
  • the flange 24 may be a separate piece that is bonded to the side wall 14, such as during manufacturing, or may be formed as a part of the side wall 14 through e.g. extrusion.
  • the upper panel 16 of the lid 10 may adhere to the upper or lower face of the flange 24, or the upper panel 16 of the lid may be an extension of flange 24.
  • the flange 24 is shaped and dimensioned so that the low point 28 of the flange 24 abuts and rests upon the upper face 29 of the rim 30 of the container 12 when the lid 10 is in use.
  • the flange 24 may be substantially horizontal and planar with the upper panel 16, or the end 32 of the flange 24 may extend upward as shown in Figures 2 and 3.
  • Adherence of the lower part 22 of the side wall 14 in the channel 38, 46 of the retention ring 18 may be accomplished with adhesive, such as a cold-seal adhesive.
  • adhesive such as a cold-seal adhesive.
  • the coupling of the lower part 22 of the side wall 14 of the lid 10 with the retention ring 18 may be achieved by heat seal, heat-stake, or pierce joint method.
  • the channel 38 provides an increased surface area to adhere to the lower part 22 of the side wall, thereby strengthening the connection between the two pieces 14 and 18 of the lid 10.
  • an adhesive is placed between the lid 10 and the retention ring 18.
  • the adhesive is placed in the channel 38, 46 of the ring 18, or the adhesive may be applied to the lower part 22 of the side wall 14 of the lid 10.

  • a product such as ice cream, a beverage, baby formula, medicine, and the like. This step may also take place before step 220, i.e. the container 12 may be filled with the product prior to placing it within the retention ring 18.
  • a projection retention ring 60 has intermittent projections 62 is shown in Figure 10.
  • retention ring 60 has an inner face 42 of the retention ring 18 shaped to accommodate the shape of the container 12.
  • the inner face 42 of the retention ring 60 may be angled.
  • the projection retention ring 60 has a base 68 which is formed to have a continuous ring structure and sized to have an interference fit with the outer wall of a container. Projection outwardly from the bottom of the base 68 may be a rim 70.
  • the projection retention ring 60 provides a method of securing a lid to a container by placing the projection retention ring 60 below the lid and around the container, lifting the projection retention ring 60 to a point near the top of the container, so that there is an interference fit between the retention ring and the container; and pushing a lid down on the container to affix the lid to the projection retention ring 60.
  • the lid may be further affixed to the retention ring by bonding.
  • the intermittent projections 62 have an upright portion 64 and an outward portion 66 extending from the upright portion 64.
  • the upright portion 64 extends upward to a distal end having an upper taper 72.
  • An outward portion 66 extends outward to a distal end having an outward taper 74.
  • the upper taper 72 is designed to insert partially into and thus secure to a rim 30 of a container 12 when the projection retention ring 60 is assembled to the container, as shown in Figure 11 and 12. By this arrangement, the projection retention ring 60 is more securely held to the container 12 thus increasing the security of the non-tamper feature.
  • the outward taper 74 is designed to insert partially or wholly into a line of weakness 23 on a lid 10, as seen in Figure 12.
  • the line of weakness 23, which can be seen in Figures 3, 4, and 6B, can be a thinning of material of the side wall 14, that permits tearing and separation of the upper part 20 and the lower part 22.
  • the line of weakness 23 may take the form of intermittent perforations.

Abstract

Un couvercle inviolable est fixé à une bague de retenue. La bague de retenue présente une face interne dimensionnée pour présenter un ajustement serré avec une paroi externe d'un récipient. Sont également enseignés des procédés de fixation du couvercle, par exemple, le placement de la bague de retenue sous le couvercle et autour du récipient ; le levage de la bague de retenue jusqu'à un point proche de la partie supérieure du récipient, de sorte qu'il y ait un ajustement serré entre la bague de retenue et le récipient ; et la poussée du couvercle vers le bas sur le récipient pour fixer le couvercle à la bague de retenue.
