  • Methods for creating sealed packages using dimpled films
    Patent number: 11465789
    Abstract: Methods, apparatuses and systems for sealed dimpled film packages. A vacuum box having apertures, a dimpled bottom film sheet is placed on the base plate and an item to be packaged can be placed on the bottom dimpled film sheet. A top film sheet in a clamp frame is heated to a processing temperature and lowered towards the item and dimpled bottom film sheet. Vacuum suction causes sealing of the clamped top film sheet against the package from the base to the perimeter extending at an angle more than 5 degrees. The top film sheet is pulled down using the vacuum suction into contact with the dimpled film sheet from the base perimeter on the dimpled film sheet outward toward the perimeter of the dimpled film sheet forming a seal.

  • Disposable bonnet raincoat
    Patent number: 4541128
    Abstract: A disposable bonnet raincoat and method is disclosed which includes a tubular length of plastic material (10) which is folded upon itself to define interior flaps (20) and (24) and exterior flaps (18) and (16). At a fold line (30) of the interior flaps (20) and (24) there is an elongated slot (C) through which the head of the wearer protrudes to define a bonnet (A) for protecting the head of the wearer. The remainder of the tubular plastic sheeting provides a protective apron (B) around the body of the wearer in which he may sit or stand for protection against the weather.
