Problems solved by technology

These pourable products are typically sold in large quantities (e.g., 30-50 lbs.) and in bulk sizes that are difficult for the average person to handle.
Even more difficult than carrying these bags is pouring the product from the bulky bag.
This often results in spilling of the product, which goes from not coming out at all to rapidly falling from the bag and outside of the target area.

Embodiment Construction

Bag with Curved Perforations Only

[0017]With reference to FIGS. 1-3, a bag 10 is illustrated. Bag 10 includes a front panel 12 and a back panel 14. As shown, front and back panels 12,14 are flat to demonstrate their respective shapes before being filled with product. Front panel 12 and back panel 14 share a first end portion 16 and a second end portion 18.

[0018]Front panel 12 and back panel 14 further share a first side portion 20 and a second side portion 22. First and second end portions 16, 18 and first and second side portions 20, 22 present respective outermost edges 24a-d, which define an outer boundary or periphery 26 of the bag 10. Outermost edges 24a and 24b oppose, and are substantially parallel to, one another, while outermost edges 24c and 24d oppose, and are substantially parallel to, one another. Furthermore, outermost edges 24c and 24d are substantially perpendicular to outermost edges 24a and 24b.

[0019]Each of the first and second end portions 16, 18 intersects with ...

Abstract

A novel bag for holding, transporting, and pouring a bulk product is provided. In one embodiment, the bag comprises a curved, perforated section at one corner. The section can be removed by tearing along the perforation, thus forming a spout for pouring the product from the bag. In another embodiment, the bag further comprises a second perforated section extending the majority of the way (and preferably the entire way) horizontally across the bag. In this embodiment, the bag could alternatively, or additionally, be opened by tearing along the second set of perforations and separating the resulting two sections of the bag. The bag is typically formed of plastic, and can be used for salt, animal food, and other pourable products.

Description

RELATED APPLICATIONS[0001]The present application is a continuation of U.S. patent application Ser. No. 13 / 787,093, entitled BULK BAG WITH PERFORATED SECTIONS, filed Mar. 6, 2013. U.S. application Ser. No. 13 / 787,093 claims the priority benefit of provisional applications entitled BULK BAG WITH MULTIPLE PERFORATED SECTIONS, Ser. No. 61 / 607,321, filed Mar. 6, 2012, and BULK BAG WITH CURVED PERFORATION, Ser. No. 61 / 607,274, filed Mar. 6, 2012. Each of these applications is incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention is broadly concerned with the field of bags for holding pourable products such as salt. More particularly, the inventive bags have a curved, perforated section at one corner and, in some embodiments a second perforated section that extends substantially, and preferably entirely, horizontally across the bag, for removal and pouring of the product from the bag.[0004]2. Description of the Prior Art[000...
