Container with vented blown finish
A container with a neck having a protrusion adapted to engage a sealing lid when the lid is placed on the container. The sealing ring or protrusion has a discontinuity, forming a gap when the lid is engaged on the container. The gap allows gas to escape during heating of product within the container when the lid is engaged.
1 . A container system, comprising:
a lid, comprising
a top surface;
a skirt extending from said surface; and
a sealing ring around an inner surface of said skirt; and
a container, comprising
a neck having a protrusion along a periphery of said neck, and said protrusion adapted to engage said sealing ring when said lid is placed on said container;
at least one of the sealing ring and the protrusion having a discontinuity forming a gap in said sealing ring or said protrusion;
wherein the container system allows gas to escape from within the container during heating of a product contained within the container when said lid is engaged on said container.
2 . The system of claim 1 , wherein said top surface is substantially planar.
3 . The system of claim 1 , wherein said sealing ring is continuous.
4 . The system of claim 1 , wherein said protrusion is continuous.
5 . The system of claim 1 , wherein said protrusion is along a rim of said neck of said container.
6 . The system of claim 1 , wherein said container further comprises:
a side wall connected to said neck; and
a base connected to said side wall;
wherein said side wall and said base are joined, creating an inner cavity capable of containing a product.
7 . The system of claim 1 , wherein the gas escapes from said system through a recess resulting from said discontinuity, when said lid is engaged on said container.
8 . The system of claim 1 , wherein said container further comprises two ridges extending from said side wall, for gripping said container, said ridges also being raised, defining a distance between said ridge and said side wall.
9 . The system of claim 1 , said container further comprising an indentation below the neck to facilitate removal of said lid.
10 . The system of claim 1 , wherein said lid comprises a single sealing ring.
11 . A container comprising:
a neck having a protrusion along a periphery of said neck, and said protrusion adapted to engage a sealing ring on a lid when the lid is placed on said container;
at least one of the sealing ring and the protrusion having a discontinuity forming a gap in said sealing ring or said protrusion;
wherein the container allows gas to escape from within the container during heating of a product contained within the container when the lid is engaged on said container.
12 . The container of claim 11 , wherein said protrusion is along a rim of said neck of said container.
13 . The container of claim 11 , wherein said protrusion is continuous.
14 . The container of claim 11 , wherein the protrusion contains a discontinuity.
15 . The container of claim 11 , wherein said container further comprises:
a side wall connected to said neck; and
a base connected to said side wall;
wherein said side wall and said base are joined, creating an inner cavity capable of containing a product.
16 . The container of claim 11 , wherein the gas escapes from said system through a recess resulting from said discontinuity, when the lid is engaged on said container.
17 . The container of claim 11 , wherein said container further comprises two ridges extending from said side wall, for gripping said container, said ridges also being raised, defining a distance between said ridge and said side wall.
18 . The container of claim 11 , said container further comprising an indentation below the neck.
19 . A method of containing a heatable product comprising placing said heatable product in a container that comprises:
a neck having a protrusion along a periphery of said neck, and said protrusion adapted to engage a sealing ring on a lid when the lid is placed on said container;
at least one of the sealing ring and the protrusion having a discontinuity forming a gap in said sealing ring or said protrusion;
wherein the container allows gas to escape from within the container during heating of a product contained within the container when the lid is engaged on said container.
20 . The method of claim 19 , wherein said sealing ring is continuous.
21 . The method of claim 19 , wherein said protrusion is continuous.
22 . The method of claim 19 , further comprising placing a lid on said container, said lid comprising:
a top surface;
a skirt extending from said surface; and
a sealing ring around an inner surface of said skirt.
23 . The method of claim 22 , wherein said top surface is substantially planar.
24 . The method of claim 19 , wherein said product is selected from cheese, sauces, pastas, noodles, rice, grains, meats, vegetables, nuts, fruits, and legumes.
