Abstract
A bag construction filled with dispersible material. The bag construction has first and second panel sections, first and second side gusset sections and a bottom gusset panel section. The various panel sections are fastened together to form a generally rectangle shape with a flat bottom. The bottom gusset panel section has one or more distribution apertures in it. A removable panel layer is provided for covering the one or more apertures. When the removable panel layer is removed, the bag can be held so that the dispersible material disperses through the apertures as appropriate.
Description
- The present invention relates to a bag or pouch construction. In particular, it relates to a bag intended to be filled with dispersible materials, wherein the bag has a flat bottom with apertures therein and a removable layer closing the apertures until use.
- A wide variety of items comprise materials which, in use, are dispersed or spread over an area. Many of these items include dry powder or particulate materials. The term “dispersible materials” as used herein is intended at least to include pellets, grains, powders, and any combinations thereof. Examples of these include, but are not limited to, icing salts, seeds, insecticides, chalk, etc.
- Some improved arrangements for spreading particulate materials have been disclosed, for example, in U.S. Pat. Nos. 5,882,120 and 5,709,479. However, the arrangements have several problems relative to the particular usage to which the present invention is directed.
- The prior art bag arrangements are difficult to store and arrange because the bottom portion does not have a design which allows the bags to stand upright. A storage bag which stands upright for product storage and point-of-sale display is desirable because such a bag arrangement provides an easier method of storing and stacking for distributors and retail merchants.
- Additionally, the prior art bag arrangements are not easily filled since they have limited expandability along the sides and bottom portion. This results in less volume and amount of material being filled into the bag. Also, the rib-and-trough closure system of prior art bag arrangements is expensive to manufacture and interferes with a bottom arrangement which would allow the bag to stand upright. Furthermore, often particulate materials become stuck inside the trough portions of the closure system. Undesirably, this may cause a lack of a good seal which can lead to leaks and/or contamination of the particulate material therein.
- Accordingly, an improvement is sought which would be simpler and yet allow a bag to stand upright, while also providing for dispersability when desired.
- The bag construction of the present invention is directed to a bag or pouch for dispersing dispersible material. The bag has first and second panel sections, first and second side gusset panel sections, and a bottom gusset panel section. The various panel sections are fastened together to form a generally rectangular shape with flat bottom. The bottom gusset panel section has one or more distribution apertures in it. A removable panel layer is provided for covering the one or more apertures. The removable panel layer is removably fastened to the outer surface of the bottom gusset panel section.
- When the bag construction of the present invention is used, the removable panel layer covering the one or more apertures is removed to uncover the one or more apertures. In that way, dispersable material can be dispersed through the one or more apertures.
- In a further embodiment, a tape section or other fastening mechanism is provided so that following use of the bag construction where there has been dispersion so that some of the dispersible material has been removed from the bag, the bottom gusset panel is folded or rolled from one of its edges toward the opposite edge so that the apertures are covered. The tape section or other fastening mechanism is then used to fasten one of the panel sections to either the bottom gusset panel section or the other of the panel sections.
- In this way, a simple and efficient bag construction is formed which provides for upright display, easy uncovering of apertures in the bottom gusset section so that dispersion can take place and, in a further embodiment, a mechanism for covering the one or more apertures so that the dispersible material can be further stored and used again.
