DETAILED DESCRIPTION OF EMBODIMENTS

[0024] In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of exemplary embodiments. It should be apparent, however, that exemplary embodiments may be practiced without these specific details or with an equivalent arrangement. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring exemplary embodiments. In addition, unless otherwise indicated, all numbers expressing quantities, ratios, and numerical properties of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term “about.”

[0025] Embodiments of bag apparatus and methods of manufacture thereof are disclosed. Apparatus of embodiments advantageously include a bag having handles and a stab extending from a single side of the bag at the top or open end thereof. The tab configuration facilitates support of the bag on a dispenser rack while permitting a front of the bag to be pulled forward to separate from the back of the bag, which is secured to the rack by the tab. The bag may have handles also configured to mount the bag on the dispenser. For example, the handles may define slits or openings through which rods of a dispenser rack pass through. The bag may thus be supported by the dispenser rack, with a back portion held stationary during separation by a user of the front of the bag from the back of the bag. Accordingly, the bag may be held in an open position on the rack for filling the bag with items. In an embodiment, the tab may be centrally disposed between two handles.

[0026] In an embodiment, the tab be configured to tear away from the bag when the bag is removed from a dispenser rack. For example, material connecting the bag to the tab may be perforated, or otherwise weakened by now known or later developed methods, for enabling tear-away separation of the tab from the bag with sufficient force.

[0027] In embodiments, a reusable bag configured for flexibility and conformability, and formed of any now known or later developed material, including woven or non-woven polymeric material, such as, for example polypropylene, or polyethylene is implemented. For the example, the bag wall material may comprise recycled polyethylene. Consumer demand for plastic bags has previously been met by providing thin plastic bags that are flexible, light, and inexpensive, but at the expense of durability and typically configured limited or single use. Recently, consumer demand has increasingly required flexible, thin, and light bags having sufficient strength for multiple uses. Reusable bags with handles and having flexibility, and minimal materials and manufacturing costs are disclosed.

[0028] A reusable bag with handles is shown in FIG. 1. In particular, FIG. 1 shows a front, top perspective view of a bag 100 including a bag body including a first wall aligned and joined to a second wall, forming two sides 103, a top 105, and a bottom 107, leaving an open unsealed edge at the top 105. The walls may be formed of any now known or later developed material such as polypropylene and polyethylene. The first wall and the second wall may be formed of the same material, and the sides 103 and the bottom 107 may be formed of the same material as the walls. The sheet material may be clear, colored, or printable, woven or non-woven.

[0029] A thickness of the sheets or bag walls may be any useful thickness, and preferably have a thin profile. In some embodiments, a polypropylene fabric bag includes walls and a bottom each having a thickness lying in a range of 0.0002 inches through 0.0040 inches. In some embodiments, a thickness of a polypropylene non-woven bag bag is selected from a range of thicknesses, measured in units of gram weights, from 30 grams per square meter to 150 grams per square meter.

[0030] In embodiments, a bag 100 is formed of a single sheet that is folded and configured to form the first wall, the second wall, the side panels 103, and the bottom 107.

Methods include a step S8003 of cutting the sheet to form a pair of handles extending from a top of the bag.

[0044] Further, methods include a step S8005 of cutting the sheet to form a tab on the first side of the bag. The tab extends from the top portion of the bag at the opening. Methods include a step S8007 of folding the sheet to form a bag having the first side and the second side, which together define the opening at the top of the bag. In embodiments, the tab is located on only a single side of the bag. In some embodiments, multiple tabs may be formed on the single side of the bag. No such tab is formed on the opposite side of the bag to retain the opposite to the rack during opening and filling of the bag.

[0045] Methods include a step S8009 of forming an opening in the tab. Further, methods include forming openings in the handles.

[0046] FIGS. 9A-9B shows a bag in accordance with embodiments being opened on a dispenser rack. The bag includes a body 101, sides 103, an opening 105, a bottom 107, and handles 109. The handles 109 are configured to be attached to a rod or similar member extending from the dispenser rack. The bag includes a tab 115 defining an opening 117 and located on only a single side of the bag. The opening 117 is a slit through which a member extends from the dispenser rack. A front side of the bag body 101 is tabless and therefore can be freely pulled away from the rack whilst the back side of the bag is fastened to the rack by the handles 109 and the tab 115, thus opening the bag. The tab is on only a single side of the bag to permit opening of the bag before removal from the rack. Accordingly, the bag may be opened on the rack for filling by pull the tabless front side of the bag away from the rack under a first force.

[0047] In some embodiments, the tab 115 is configured to easily separate or tear away from the bag body 101. Accordingly, the bag may be opened for filling under a first force as discussed above, and then separated from the rack under a second stronger force. For example, FIG. 9B shows the bag being separated from tab 115, which remains on the rod of the dispenser rack. As shown in FIG. 9A, before the tab 115 is separated from the bag body 101, and as a front of the bag is removed from the dispenser rack, the tab 115 retains the back side of the bag body 10, causing the bag to open. The bag may be then fully removed, for example after filling, by pulling the bag with sufficient force to separate the tab 115 from the back side of the bag body 101.
