Container sealing system

An insert for a container having a body defining a volume, a neck defining an opening in the body and a cover configured to threadingly engage the neck, the insert comprising:

• an outer wall configured to fit within the opening of the container and defining the periphery of the insert, the outer wall having an upper edge including a lip extending radially outward from the upper edge to prevent the insert from being pushed to far into or through the neck and a lower edge, with the lip including one of a tooth and notch configured to engage one of the notch and tooth formed in the neck;
• an upstanding spout located within the outer wall;
• a bottom wall connecting the lower edge of the outer wall and the spout to form a channel between the outer wall and the spout, wherein the tooth/notch combination inhibits rotation of the insert in the opening and aligns the insert in a preselected orientation;
• and
• wherein the lip includes a first portion having a first radius and a second portion having a second radius, wherein the first radius is larger than the second radius with the first portion forming a seal with the neck at a knit line of the container when the cover is threaded onto the neck.

A container having a knit line, the container comprising:

• a body defining a partially enclosed volume having an access opening defined by a neck, the neck defining a notch;
• and
• an insert coupled to the neck, the insert comprising:
• an outer wall configured to fit within the opening of the container and defining the periphery of the insert, the outer wall having an upper edge and a lower edge, with the upper edge including an annular lip extending radially outward to prevent the insert from being pushed to far into or through the neck;
• a tooth extending from the lip and configured to insert into the notch defined by the neck of the container;
• an upstanding spout located within the outer wall;
• and
• a bottom wall connecting the lower edge of the outer wall and the spout to form a channel between the outer wall and the spout,
• wherein the lip includes a first portion having a first radius and a second portion having a second radius, wherein the first radius is larger than the second radius with the first portion forming a seal at the knit line of the container when the cover is threaded onto the neck.

A method for aligning and sealing a container having a knit line, a neck defining an opening in the container, and a cover configured to threadingly engage the neck, the method comprising the steps of:

• providing an insert having an annular lip extending radially outward;
• configuring the insert to fit within the opening of the container;
• configuring the annular lip with a first portion having a first radius and a second portion having a second radius, wherein the first radius is larger than the second radius with the first portion forming a seal at the knit line of the container when the cover is threaded onto the neck;
• providing a tooth on the annular lip;
• and
• configuring the tooth to insert into a notch defined in the neck, wherein the tooth/notch combination aligns the first portion of the insert with the knit line of the container.
