Deformable Plastic Caps for containers that counteract the effects due to changes in Barometric pressure

摘要

Refers to a deformable Type Cover for plastic containers that perform a function such that it avoids the deformation of the Wall of the containers by changes in Barometric pressure when they have been sealed with the lid in mention.The Cover can be made of plastic, Aluminium or plastic / paper and / or Aluminum and has the property of changing Shape as a result of the change in Barometric pressure when it is hermetically Sealed in a plastic container.The walls of plastic containers sealed with this type of Cap is not distorted by changes in Barometric pressure, so that the packaging can be completely or partially filled with a liquid or solid Contents, and then be sealed to Great Heights with respect to the level of L Set sea, then transported to sea levelWithout deformation in the appearance of the Wall. Plastic Containers are CUPS, bottles, Jars and containers of different sizes and shapes made by injection or Blow Forming processes
