SADDLE BAGS
Bags on a sheet of flexible material are made by doubling back the sheet to form closed bottoms on multiple bags, wherein doubling back the sheet forms front and back panels on the multiple bags, followed by forming side edges on the multiple bags by joining the front and back panels to each other at predetermined locations to form closed seams at the predetermined locations, the closed seams forming the side edges of the multiple bags, and the side edges attaching adjacent multiple bags to each other.
This application is a Division of U.S. application Ser. No. 13/886,812 filed May 3, 2013, which claims the benefit of U.S. Provisional Patent Application No. 61/643,546 filed May 7, 2012.
FIELD OF THE INVENTIONThe present invention relates to a system and method for making receptacles in the form of bags.
BACKGROUNDU.S. Pat. No. 3,380,646 discloses a container of thermally weldable, plastic material and a method of producing the container by welding together multiple strips or sheets of plastic material to form a container having a welded closed, bottom part of the container. An open top of the container is collapsed and flattened to provide a pinch closed top.
A need exists for a method and system for making multiple bags from a single sheet of flexible material, wherein the bags are attached to one another in a predictable orientation. It would be advantageous for the bags to be separated from the sheet.
SUMMARY OF THE INVENTIONBags on a sheet of flexible material are made by doubling back the sheet to form closed bottoms on multiple bags, wherein doubling back the sheet forms front and back panels on the multiple bags, followed by forming side edges on the multiple bags by joining the front and back panels to each other at predetermined locations to form closed seams at the predetermined locations, the closed seams forming the side edges of the multiple bags, and the side edges attaching adjacent multiple bags to each other.
For one embodiment, doubling back the first side of the sheet forms the front and back panels on the multiple bags in the first series, and doubling back the second side of the sheet forms the front and back panels on the multiple bags in the second series.
Embodiments of the invention will now be described by way of example with reference to the accompanying drawings.
One or more bags are made according to a system and method to be described. The one or more bags include a range of bag sizes, from smaller bags in the form of pouches and larger bags for holding dry animal food, seeds and agricultural chemicals.
With reference to
The one or more bags 100 are made from a sheet 102 selected from a range of different materials, including paper, and polymeric materials. The sheet 102 includes a range of sizes including a film unrolled from a roll of film 102a,

This description of the exemplary embodiments is intended to be read in connection with the accompanying drawings, which are to be considered part of the entire written description. In the description, relative terms such as “lower,” “upper,” “horizontal,” “vertical,”, “above,” “below,” “up,” “down,” “top” and “bottom” as well as derivative thereof (e.g., “horizontally,” “downwardly,” “upwardly,” etc.) should be construed to refer to the orientation as then described or as shown in the drawing under discussion. These relative terms are for convenience of description and do not require that the apparatus be constructed or operated in a particular orientation. Terms concerning attachments, coupling and the like, such as “connected” and “interconnected,” refer to a relationship wherein structures are secured or attached to one another either directly or indirectly through intervening structures, as well as both movable or rigid attachments or relationships, unless expressly described otherwise.
Patents and patent applications referred to herein are hereby incorporated by reference in their entireties. Although the invention has been described in terms of exemplary embodiments, it is not limited thereto. Rather, the appended claims should be construed broadly, to include other variants and embodiments of the invention, which may be made by those skilled in the art without departing from the scope and range of equivalents of the invention.
Claims
1. Multiple bags on a sheet of flexible material, comprising:
- a doubled back first side of the sheet forming closed bottoms on multiple bags in a first series of multiple bags, and a doubled back second side of the sheet forming closed bottoms on multiple bags in a second series of multiple bags, wherein the doubled back first side of the sheet forms front and back panels on the multiple bags in the first series, and the doubled back second side of the sheet forms front and back panels on the multiple bags in the second series;
- the front and back panels being joined to each other at predetermined locations and providing closed seams at the predetermined locations, the closed seams comprising side edges on the multiple bags; and
- adjacent multiple bags being attached to each other at the side edges.
2. The bags of claim 1, comprising:
- perforations through the sheet at the predetermined locations for detaching respective multiple bags from the sheet.
3. The bags of claim 1, comprising:
- first handle openings through the sheet, wherein the multiple bags in the first series include the first handle openings; and
- second handle openings through the sheet, wherein the multiple bags in the second series include the first handle openings.
