Latest Patents
One of Stevenson's latest patents is for gussetted plastic bags featuring relief seals and a method of making them. This invention allows for a disposable or reusable and reclosable gussetted plastic bag that can be compactly stored as a food container in freezers. It is designed to stand with an upright spout in a microwave oven, facilitating non-spill thawing and cooking of food contained within the bag. The bag consists of two wing-shaped pouches on either side of the upright spout. It is constructed with inner and outer skin layers that have different heat sealing temperatures, ensuring that peripheral sealing occurs only with the inner skin layers. This design allows the wing-shaped pouches to be formed from a gussetted bottom without sealing the outer skin layers of the gusset walls facing one another. Additionally, two pairs of relief seals are strategically placed adjacent to each gusset joint at both edges of the bag, with each seal positioned at a 45-degree angle off the gusset joint and featuring a rounded peak shape. The heat seals are created by applying heat near each gusset joint using a hot bar or other heat sealing device after the bag's formation.
