VENTING SYSTEM FOR OVENABLE CONTAINERS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240051728 titled 'VENTING SYSTEM FOR OVENABLE CONTAINERS

Simplified Explanation

The invention is an ovenable packaging structure with a one-way valve. The structure consists of a laminate with an outer layer and an inner layer, both having cut lines. The outer layer has a flap that can be separated from it, while the inner layer has a portion that can be separated along its cut line, creating an opening into the packaging structure. The layers are adhered together with an adhesive that includes a channel of pressure sensitive adhesive surrounding both cut lines, creating an adhesive-free valve chamber within the channel.

  • The invention is an ovenable packaging structure with a one-way valve.
  • The structure is made of a laminate with an outer layer and an inner layer.
  • The outer layer has a flap that can be separated from it.
  • The inner layer has a portion that can be separated along its cut line, creating an opening into the packaging structure.
  • The layers are adhered together with an adhesive that includes a channel of pressure sensitive adhesive.
  • The channel of adhesive surrounds both the outer and inner cut lines.
  • The channel of adhesive defines the perimeter of at least one adhesive-free valve chamber within the channel.
  • The valve chamber includes a portion of the outer and inner cut lines.

Potential Applications:

  • Food packaging that can be heated in an oven without removing the packaging.
  • Packaging for ready-to-eat meals that can be easily opened and heated.
  • Packaging for perishable goods that require ventilation to maintain freshness.

Problems Solved:

  • Provides a convenient and efficient way to package food that can be heated in an oven.
  • Allows for easy opening of the packaging without the need for additional tools.
  • Ensures proper ventilation and freshness of perishable goods.

Benefits:

  • Simplifies the packaging and heating process for food products.
  • Reduces the need for additional packaging materials or tools.
  • Improves the convenience and efficiency of food preparation.
  • Maintains the freshness and quality of perishable goods.


Original Abstract Submitted

the invention comprises an ovenable packaging structure having an integral one-way valve. the laminate structure comprises an outer layer having a cut line which defines a flap that is separable from the outer layer, wherein the outer layer is adhered to an inner layer having a cut line which is offset from the outer cut line and defines a portion that is separable from the inner layer along the inner cut line and defines an opening into the packaging structure. the adhesive between the layers comprises, in an embodiment, a channel of pressure sensitive adhesive which surrounds both the outer cut line and the inner cut line, wherein the channel of pressure sensitive adhesive defines the perimeter of at least one adhesive-free valve chamber within said channel. the valve chamber comprises at least a portion of the outer cut line and the inner cut line.
