Benefits of technology

Inventors have developed a new way to make sure items like caffeine are safe from being exposed when they shouldn't get wet during storage. They use special plastic films called bags filled with ice cubes instead of regular cups used for storing these things. These filters help keep them fresh over time without losing their effectiveness due to evaporation.

Problems solved by technology

Prior technical solutions for reducing or controlling pressure build-up within containers like coffee bags involve adding special materials into their structure itself. However, these techniques may also lead to unwanted side effects when used alone due to potential negative environmental impacts caused by volatile compounds released during production processes. Therefore it becomes necessary to develop a solution where they don't affect any external factors associated with them while still maintaining effective control over internal pressures.

Embodiment Construction

[0016]The present invention relates to an interior-mountable pressure relief valve for packaged products such as coffee. In many applications, an exterior-mounted valve is undesirable for various reasons including the protrusion it produces on the outside of the package. The present invention places the valve on the inside of a package carrier that can include a filter medium. This carrier can be processed and the delivered to a packaging company that takes it from a carrier tape and dispenses it as a single piece dose. The carrier can then be heat sealed to the inside wall of the packaging material. The interior-mounted valve of the present invention can be a pre-oiled assembly with a valve in a pocket containing the filter medium and can be delivered and dispensed in a single button style using a simple cut off, pick and place and heat staking methods.

[0017]Turning to FIG. 1, an exploded perspective view of an embodiment of the valve device 1 of the present invention can be seen. A p

Abstract

An interior-mountable pressure relief valve for packages containing food products such as coffee that normally tend to out-gas. The relief valve of the present invention can be made by thermoforming a pocket of a barrier type of semi-rigid film that has a heat seal membrane on one side. An indent can be made in the bottom of this pocket to receive a filter medium that covers an aperture in the bottom of the pocket. The filter medium can be heat-staked to the pocket. A pressure relief valve known in the art containing a base layer, a pair of rails and a flexible membrane can be placed in the pocket. This valve and pocket assembly can be can be treated with a mesh membrane that is heat sealable to the seal side to prevent disassembly or contamination. The product can then be wound on a level wound spool for shipping to an end user. The end user can take the carrier tape and dispense it into a single piece dose and then heat seal the carrier to the inside wall of the package.
