Abstract
Description
- The disclosure relates to pouches or bags. In particular, the disclosure relates to versatile, foldable, flexible, reusable pouches or bags with convertible carrying configurations.
- Conventional, single use plastic bags used worldwide are ubiquitous and have a tremendous impact on the environment, contributing to waste and pollution. Such bags are nonetheless desired by consumers because they are inexpensive, light, and flexible enough to easily conform to goods and fold compactly for packaging, and yet strong enough to support a full load of goods.
- Conventional bags, may include one or more handles. For example, some bags are made of a non-woven fabric sheet or sheets arranged to form a bag and defining an opening. To ensure adequate strength for both single and repeated uses, sewing is used to seal side and bottom edges, in addition to handle attachment points for convention reuseable bags.
- For example, the top peripheral edge of the conventional bag may include a double-layer portion that is formed by folding down the top portion of the bag at the opening. The double-layer portion is both sewn and bonded by discontinuous ultrasonic sealing. A strip having two ends is attached to the bag to form a handle. Each end of the strip may be arranged to contact the double-layered portion of the bag by an interposing attachment member to provide additional strength. The handle and attachment portion are fastened to the double-layer of the bag by a combination of sewing, heat sealing, and ultrasonic sealing. The handles are fixed in length and non-adjustable, presented only in a hand-carry or shoulder carry configuration.
- A need has been recognized for bags with versatile, multi-functional handles and having a strength sufficient for multiple while having a thin profile, flexibility, and a manufacturing cost corresponding competitive to conventional single use bags. A versatile bag having a flexible, thin profile, a handle arrangement constructed for multiple hold and carry configurations, and a strength and durability suitable for multiple, repeated bag uses while having a manufacturing cost and material cost competitive with conventional bags is disclosed. An increasing and unmet demand exists for packaging configured for multiple uses to minimize material waste and environmental impact. Bag apparatus and methods of manufacture thereof in accordance with embodiments disclosed herein meet, inter alia, these needs and demands.
- Bag apparatus and methods of manufacture thereof in accordance with embodiments of the disclosure enable efficient use of packaging materials, minimizing packing costs, maximizing utility, and minimizing environmental impact of disposable bag and pouch usage. Reusable bags in accordance with embodiments of the disclosure are configured for compact folding, and may include a strong, resilient handle pair. Bags of some embodiments may include a plurality of gusset panels enhancing resusability and foldability. Bags of embodiments may be formed of woven or non-woven material that is suitable for heat and pressure sealing.
- For example, in an embodiment, the foldable bag or pouch is formed of a now known or later developed material, which may be woven or non-woven, having sufficient strength, flexibility, and durability for carrying a load and for re-use. In some embodiments, the material comprises polyethylene terepthalate (“PET”). For example, the PET may be recycled (“rPET”). In some embodiments, the material may comprise polypropylene.
- The bags or pouches may be cut and constructed to be any suitable size or shape. By way of example, bag apparatus of an embodiment may be formed to have a width of 18 inches, a length of 17 inches, and a bottom of 6 inches across. In an embodiment, a thickness of the bag lies in a range of thicknesses, measured in units of gram weights, of 30 grams per square meter to 300 grams per square meter, for example. The bag apparatus has handles and is foldable for efficient storage and flexible for conformability to contents.
- The bag handles of embodiments of the disclosure are configured on the bag body for converting from a hand-carry configuration, to a shoulder-carry configuration, or to a backpack configuration. The bag includes a pair of handles formed of straps, each having a first end and a second end. The straps are attached at respective first ends to the bag body at a lower portion of a first side thereof. The straps are attached at respective second ends to the bag body at an upper portion of a second side thereof. The straps extend from the attached second ends each through loops formed by or fixed to the bag body. Accordingly, the straps are each loosely attached to the bag body above the respective ends at which they are instead fixedly attached.
- Specifically, the straps in accordance with embodiments are slidably attached by the loops formed on the second side, or back side of the bag. This permits the straps to freely travel through the loop enclosure until sufficient pressure is applied to force the straps each against their respective loops thereby restraining further movement to cause the straps to be positioned in a specified configuration. The straps may thus be positioned in a handle, hand or shoulder-carry configuration by sliding the straps to a fully extended length above a top of the bag. The straps may alternatively be positioned in a backpack configuration by sliding the straps to a fully extended length toward a side and bottom of the back, and the first ends of the straps.
- A bag apparatus in accordance with an embodiment includes a first bag wall; a first side panel; a second side panel; a second bag wall aligned and joined to the first bag wall by the first side panel and the second side panel at a first heat sealed side edge, a second heat sealed side edge, respectively; a bag bottom comprising a substantially planar, foldable surface, the first and the second bag walls, the first and the second side panels, and the bottom formed of a single sheet and together arranged to form a bag defining an opening at a top thereof; a handle attached to a lower portion of the first wall at a first end, and an upper portion of the second wall at the second end; a transverse panel heat-sealed to the upper portion of the first wall and configured to include a gap in the seal that forms a loop through which the handle is slidable.
- A system in accordance with an embodiment includes a convertible, reusable backpack bag with handles or straps configured and arranged for conversion to a backpack, a handbag, and/or a shoulderbag. Systems include a fastener configured to join separate handles together.
- A method in accordance with an embodiment includes providing a planar, flexible sheet comprising a material suitable for heat sealing or sewing. Methods include folding the sheet and heat sealing to form an open-ended bag having a front, a back, a first side, a second side, and a bottom, wherein the first side and the second side and the bottom are constructed and arranged to be foldable inward in a configuration that causes the bag to naturally collapse into a folded configuration; and forming or attaching a plurality of handles connected to an upper portion of the first side and a lower portion of the second side, and slideable through loops formed on the second side.

The process includes attaching the handles at a lower portion of the back side of the bag at S12005. The handles are fixedly attached by heat-sealing, or by sewing, or by a combination thereof. - The handles are attached at an opposite end to an upper portion of the front side of the bag at S12007. The handles are attached to the upper portion of the front side of the bag by heat-sealing. The handles are otherwise separated from the back side of the bag. At S12009, a transverse member is applied to the back side of the bag. The transverse bag is heat sealed to the back side of the back along a length thereof with the exception of gaps in the seal that form loops. The loops are sized and configured for the straps of the handles to pass therethrough. The length of the handle straps are sufficient for slidably moving through the loops between a handle configuration and a backpack configuration.
