Benefits of technology

The present invention provides a way to easily retract a component of a vacuum packaging appliance when certain conditions are detected. The component can be a support structure for a heat sealing strip or a bumper. The retraction is done by using a magnetic field generated by an electro-magnet or a mechanical retraction structure. The application of the magnetic field causes the component to transition from an engaged position to an unengaged position, where it no longer facilitates the formation of the heat seal. The magnetic field can be stopped when the condition no longer exists, or when a second condition is detected such as unlocking the lid or a reduction of the temperature or fluid pressure levels. The technical effect of this invention is to improve the efficiency and flexibility of the vacuum packaging process.

Problems solved by technology

As a result the application of the magnetic field, the first component is at least maintained in an unengaged position in which the first component no longer facilitates the formation of the heat seal.

Abstract

Systems (200) and methods (1300) for selectively retracting a first component of a Vacuum Packaging Appliance (“VPA”). The method comprises: causing the first component to normally be in an engaged position in which the component facilitates a formation of a heat seal along an open end of a container disposed within the VPA; detecting an existence of at least one first condition associated with the VPA; and applying a magnetic field in proximity to the component when the first condition is detected, whereby the first component is at least maintained in an unengaged position in which the first component no longer facilitates the formation of the heat seal.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims priority to U.S. Provisional Patent Application No. 61 / 752,050 filed on Jan. 14, 2013.BACKGROUND OF THE INVENTION[0002]1. Statement of the Technical Field[0003]The inventive arrangements relate to vacuum packaging and sealing appliances. More particularly, the invention concerns vacuum packaging and sealing appliances employing electromagnets for transitioning heat sealing bars between engaged positions in which heat seals are formed and unengaged positions in which no heat seals are formed,[0004]2. Description of the Related Art[0005]Various appliances are used for vacuum packaging purposes to protect perishables and other products against oxidation. Such appliances typically use a heat scaling element to form a seal at an open end of a container. The heat sealing element can include two adjacent heat sealing bars between which the open end of the container is placed. Prior to formation of the heat seal, th...
