Definitions

  • the present invention relates generally to a finish for a plastic container, and more particularly, to a smooth, user-friendly finish for a plastic container.
  • Plastic containers such as polyolefin or PET containers, may be used for packaging food, dairy, and other drinkable products.
  • Such containers can be sealed at the opening in the neck using a conventional closure such as a screw-on or push-on lid. Additionally or alternatively, these containers can be thermosealed with a suitable lid, for example, a foil lid. A thermosealed lid is designed to be pulled off to allow access to the contents of the container. Once opened, the contents can be, for example, drank directly from the container or, in the case of larger containers, spooned, poured, or grasped from the container.
  • the integrity of the lip of the container may be critical in obtaining a good seal with the closure. This is most commonly accomplished by increasing the thickness of the lip. Additionally, lip thickness may assist in improving the top-loading capabilities of the container.
  • Another issue that can arise with container lip design is that the inner edge of the lip (which is usually formed by a trimming operation) can present a sharp edge. This sharp edge can be uncomfortable and/or dangerous to the consumer, whether they are drinking directly from the container, or grasping product located within the container.
  • a container defines a longitudinal axis, and comprises a neck, a finish merging with said neck, said finish comprising a first lip, a second lip spaced apart from said first lip in a direction that is substantially parallel to the longitudinal axis, and a curved portion connecting said first lip with said second lip.
  • a method for sealing a container comprises providing a container defining a longitudinal axis and having a neck and a finish merging with said neck, the finish comprising a first lip connected to said neck, a second lip spaced apart from said first lip in a direction substantially parallel to the longitudinal axis, and a curved portion connecting said first lip with said second lip; and thermosealing a lid to the container.
  • a finish for a plastic container defining a longitudinal axis comprises a first lip, a second lip spaced apart from said first lip in a direction that is substantially parallel to the longitudinal axis, and a curved portion connecting said first lip with said second lip.
  • a container defining a longitudinal axis comprises an upper portion including a finish, said finish comprising a first lip extending about the longitudinal axis and defining a first inner radial distance from the longitudinal axis, and a second lip interconnected with said first lip, said second lip extending about the longitudinal axis and defining a second inner radial distance from the longitudinal axis, said second inner radial distance being larger than said first inner radial distance.
  • the second lip is spaced apart from said first lip in a direction substantially parallel to said longitudinal axis.

  • FIG. 7 depicts an enlarged portion of the cross-section of FIG. 6 ;
  • FIG. 8 depicts an exemplary embodiment of the container of FIGS. 5-7 after sealing.
  • Exemplary embodiments of the present invention provide a plastic container, such as a polyolefin or PET container.
  • Exemplary containers according to the present invention can include a very thin lip that is adapted for thermosealing at high sealing temperatures without undesirable deformation.
  • two lips of the neck of a container may stick together to give a strong resistance to lip deformation.
  • exemplary containers according to the present invention can include features for attaching a lid to the container, such as threads or press-on features.
  • the container finish can include two or more lips of varying inner radii in order to present the consumer with smoothly contoured contact surface when consuming products from the container.
  • FIG. 1 depicts an embodiment of a prior art container 100 having a sealing lip 101 for receiving a thermosealed lid (not shown).
  • Container 100 has a neck 102 that includes a neck flange 103 that merges with the sealing lip 101 .
  • sealing lip 101 must be thick enough so that the sealing temperature doesn't soften the plastic and cause the sealing lip 101 to sink into the container before foil sealing.
  • the top surface of the sealing lip 101 can bend and the edge 104 can curl into the interior of the container.
  • the top surface, where the seal would be formed is curved and thus has less surface area for bonding to the foil seal. As a result, the seal can fail resulting in a rejected container.
  • the lip is typically 0.5 to 1.0 mm thick, for example. Such a thickness, however, results in an increase in the amount of plastic used to make the container, which, in turn, causes the container to be heavier and more expensive to construct.
  • the flange 103 serves several purposes in such a container. First, it provides a contact point for support on a filling line. Second, the flange provides top load strength for storing and stacking containers. However, the flange adds weight to the container that is not necessarily required for structural support of the container itself. Another disadvantage of the flange 103 is that it creates a concave inner surface in which the contained product can become entrapped during storage or use, or can be hard to remove when poured from the container.
  • FIG. 2 depicts an embodiment of a prior art container 200 having a sealing lip 201 and a neck 202 merging with sealing lip 201 .
  • the container 200 avoids the weight of an added flange, the design of the lip 201 and edge 204 suffers the same drawbacks as container 100 with lid 101 and edge 104 .
  • sealing lip 201 when thermosealing container 200 , sealing lip 201 must be thick enough so that the sealing temperature doesn't soften the plastic and cause the sealing lip 201 to sink into the container before foil sealing.
  • the lip To prevent the sealing lip 121 from sinking into container 200 , the lip must be, for example, 0.5 to 1.0 mm thick. Such a thickness, however, results in an increase in the amount of plastic used to make the container, which, in turn, causes the container to be heavier and more expensive to construct.
  • the sealing lips 101 , 201 in these prior art containers suffer several drawbacks.
  • the edge 104 , 204 can be relatively sharp, causing discomfort when a consumer drinks from the container.
  • the sharpness of the edge 104 , 204 can also be increased during the thermosealing process as the lip 101 , 201 softens during sealing.
  • the edge 104 , 204 of the lip 101 , 201 can curl downward during thermosealing, resulting in an incompetent seal and a leaking container.
  • making the lips thicker results in a more competent seal and less curling, it does not typically prevent sharpening of the edge 104 , 204 , and adds undesirable weight to the container.
  • a finish having a lip according to the present invention avoids these and other drawbacks of known lips.
  • FIG. 3 a depicts an exemplary embodiment of a thermosealable container 300 according to an embodiment of the present invention.
  • Container 300 can have a finish 308 that includes an upper lip 301 , a lower lip 302 , a curved portion 303 , a neck 304 .
  • Container 300 also includes a sidewall 305 .
  • neck 304 merges with sidewall 305 ; lower lip 302 merges with neck 304 ; curved portion 303 merges with lower lip 302 ; and upper lip 301 merges with curved portion 303 .
  • upper lip 301 and lower lip 302 are substantially horizontal such that the upper lip is spaced apart at a distance S from the lower lip in a direction that is substantially perpendicular to the lower lip.
  • upper lip and lower lip may be from 0.1 mm to 0.5 mm thick.
  • the distance S can be about 0.5 to 5.0 mm.
  • upper lip 301 has an edge 306 that may be a sharp edge prior to thermosealing container 300 with a foil seal, for example.
  • container 300 has a longitudinal axis A that extends substantially through the center of container 300 .
  • neck 304 be located at a distance D 1 , measured radially from longitudinal axis A and edge 306 can be located at a distance D 2 measured radially from longitudinal axis A. In such an embodiment, distance D 2 may be greater than or equal to D 1 .
  • FIG. 3 b depicts container 300 after it has been thermosealed.
  • the plastic softens and upper lip 301 can collapse towards lower lip 302 .
  • edge 306 may contact lower lip 302 , effectively removing the sharpness of edge 306 and creating a “soft” edge from the curve that connects the neck 304 with the lower lip 302 . Because upper lip 301 and lower lip 302 are both substantially horizontal, when heat is applied during sealing, the degree to which the upper lip sinks into the container is limited by the lower lip 302 .
  • Such a container may also provide a lightweight, thin lip that remains top-load resistant.
  • the resulting sealed lip 301 , 302 can have a substantially flat surface for sealing.
  • container 300 provides a flat surface 307 for thermosealing that provides more surface area for sealing the foil to the upper lip 301 .
  • heat may be applied during thermosealing reaches the finish of container 300 , softening upper lip 301 and curved portion 303 .
  • space S may act as an insulator between upper lip 301 and lower lip 302 , so that lower lip 302 does not soften excessively, maintaining the integrity and structure of the lower lip and maintaining a substantially flat surface for accepting the seal.
  • upper lip 301 and curve 303 may collapse towards lower lip 302 and cause upper lip 301 to stick to lower lip 302 .
  • the resulting container 300 provides other advantages over the prior art containers shown in FIGS. 1 and 2 .
  • container 300 no product becomes trapped because container 300 does not have a neck flange or some other welled area for trapping product.
  • the sharp edge is eliminated because edge 306 merges into lower lip 302 , while at the same time, a flat surface 307 for thermosealing is maintained.
  • FIG. 4 a depicts an exemplary embodiment of a thermosealable container 400 according to an embodiment of the present invention.
  • Container 400 can have a finish 408 that includes an upper lip 401 , a lower lip 402 , a curved portion 403 , a neck 404 .
  • Container 400 also includes a sidewall 405 . As shown in FIG. 4 a, neck 404 merges with sidewall 405 ; lower lip 402 merges with neck 404 ; curved portion 403 merges with lower lip 402 ; and upper lip 401 merges with curved portion 402 .
  • upper lip 401 and lower lip 402 are substantially horizontal such that the upper lip is spaced apart at a distance S from the lower lip in a direction that is substantially perpendicular to the lower lip.
  • upper lip and lower lip may be from 0.1 mm to 0.5 mm thick.
  • the distance S can be about 0.5 to 5.0 mm.
  • upper lip 401 has an edge 406 that may be a sharp edge prior to thermosealing container 400 with a foil seal, for example.
  • container 400 has a longitudinal axis A that extends substantially through the center of container 400 .
  • neck 404 be located at a distance D 1 , measured radially from longitudinal axis A and edge 406 can be located at a distance D 2 measured radially from longitudinal axis A. In such an embodiment, distance D 2 may be less than D 1 .
  • FIG. 4 b depicts container 400 after it has been thermosealed.
  • a distance D 2 may be less than D 1 as described with respect to FIG. 4 a.
  • the plastic softens and upper lip 401 can collapse towards lower lip 402 .
  • edge 406 of container 400 can bend into container 400 and extend down into the container.
  • the resulting container 400 as shown in FIG. 4 b includes a flat edge 407 for thermosealing and eliminates the problems caused by having sharp edge because the upper lip bends into the container in such a manner that the edge will not be touched by the mouth of a consumer.
  • FIGS. 5-8 another exemplary embodiment of a container according to the present invention is shown.
  • the container 500 of FIGS. 5-8 can be used with a thermosealed lid, as described above in connection with previous embodiments, or alternatively, can be used with screw-on, press-on, or other known lid types.

  • the finish 508 can include threads, ridges, or other known features for retaining a screw-on, press-on, or other type of closure to the container 500 .
  • the inner edge 506 of the upper lip 501 can define a first inner radial distance X 1 from the longitudinal axis A.
  • the curved wall portion of the lower lip 502 can likewise define a second inner radial distance X 2 from the longitudinal axis A.
  • the second inner radial distance X 2 can be smaller than the first inner radial distance X 1 .
  • the relatively smooth, curved surface of the lower lip 502 defines a smaller diameter than the inner edge 506 of the upper lip 501 , and can prevent a user from contacting inner edge 506 when dispensing products from container 500 (e.g., drinking a liquid from the container or grasping solid products from the container).
