POUR BAG WITH GRIPPABLE DISPENSING FUNNEL

Abstract

A bag made of two opposing sheets, shaped to have a dispensing funnel extending outward from one side at the bottom. The bag is primarily for dry contents and constructed so that it is easy to pour dry contents with control, even if they are heavy. The dispensing funnel has a grippable spout and a flow area that allows the contents to flow through the spout easily. The grippable spout can be held in the hand, and affords more control over the flow by manually opening and shutting the opening. The structure of the funnel allows the user to hold the bag in one hand, tip the bag 45 degrees and hold on to the spout with the other hand to control the speed and direction of the flow. The bag is easy to construct and can be sold with or without contents.

DETAILED DESCRIPTION OF THE INVENTION

[0012] The bag will now be described with reference to FIGS. 1 through 5. The bag is comprised of two opposing flexible sheets that are joinable or joined together, such as by heat sealing, to create the bag's interior cavity. The sheets can be made of any flexible material including plastic, polyethylene, polypropylene, paper, cotton, polyester, etc. . . . Furthermore, the two opposing flexible sheets may be comprised of a single sheet folded in half, without departing from the spirit of the invention. The bag can hold any type of dry contents, and its structure has been designed so that any type of dry contents can be poured easily out of a dispensing funnel [5] protruding horizontally from one end of the base of the bag.

[0013] In a preferred embodiment, the two flexible sheets are cut or otherwise shaped such that the shape of the bag comprises a top end [2] that is openable to receive contents, a bottom seam [3], and two vertical side seams [1] and [4] such that the first side seam [1] joins the top end [2] and bottom seam [3] to form the back end of the bag, and the second side seam [4] extends from the top end [2] to meet the top end of dispensing funnel [5]. Dispensing funnel [5] extends outward from the front end of the bag, i.e. the side of the bag opposite back end [1], on the bottom portion of said front end. Note that the bottom seam [3] of the bag is longer than the top end [2] of the bag, such that the dispensing funnel [5] extends from the bottom of the front end of the bag. Thus, when empty the bag will appear as a rectangular body [18] with a dispensing funnel [5] extending outward from the bottom and side of the bag.

[0014] Dispensing funnel [5] is formed by the same joining and sealing of the two flexible sheets as is the interior of the bag, in other words, dispensing funnel [5] is in open connection with the interior of the bag. Dispensing funnel [5] is comprised of a grippable spout [53] and a curved flow area [51] that connects the end of the grippable spout [53] with the rectangular body [18] of the bag. Grippable spout [53] measures at least 2 inches in order to be hand-held by a user. Grippable spout [53] also comprises an opening [52] through which contents can be controllably released. The bottom of curved flow area [51] is coincident with the bottom seam [3] of the bag, and the top of curved flow area [51] is coincident with a curved seam [511] angled at least 45 degrees, as exemplified by angle [54] in FIG. 2. This two-dimensional shape means that when contents are placed in the bag resulting in the expansion of the bag and its dispensing funnel, dispensing funnel [5] will be substantially in the shape of a half-funnel, as depicted in FIG. 4.

[0015] FIG. 3 is an example of the bag filled with dry contents. When the bag is structured as described, the bag comprises a dispensing funnel [5] with a grippable spout [53] through which the bag's contents can be controllably poured. A user can hold the grippable spout [53] for control, squeeze the spout shut to stop the flow and open the spout to any desired circumference to control the speed of the flow. This is particularly useful when the contents are needed to be released precisely, for instance if the user desires to pour the contents into a smaller receptacle. The control over the flow will minimize spill and waste, especially when the contents are comprised of small particles that have a tendency to spill and scatter when poured out of the top of an ordinary bag.

[0016] The preferred dimensions of dispensing funnel [5] are shown in FIG. 2. With reference to FIG. 2, the curvature of seam [511] is comprised of increasing angles from the end of grippable spout [53] to the second side seam [4]. With reference to FIG. 2, these angles increase from 49.9 (the angle [54] being at least 45), to 52.4, to 72.9. With reference to FIG. 2, the length of the entire dispensing funnel is approximately 127 mm between opening [52] and second side seam [4], and in particular the length of grippable spout [53] is at least 2 inches long in order to accommodate the hand of a user.

[0017] The dimensions of the spout are important to the functioning of the bag. In addition to being grippable in the average human hand, the length of the spout allows contents to flow freely but not so freely that they pour out of the spout uncontrollably and the length of spout is not too long that contents can be stuck or clogged in the spout even when tilting it. The curved flow area [51] is designed to allow the contents of the bag to flow smoothly from the body and through the dispensing funnel. As this bag is only designed to hold dry contents, the curved flow area prevents contents from becoming trapped in an elbow, while creating enough resistance so that the contents pour slowly from the interior of the bag. Thus, a user can stand or sit and tilt the bag downward with minimal effort, to release its contents. Indeed the bag only needs to be tilted 45 degrees in order to release its contents. This is a vast improvement over bags that simply have an opening and must be tilted close to 90 degrees to pour.

[0018] The funnel is effective because the angle of curved seam [511] is steepest nearest second side seam [4], and gradually decreases to meet the grippable spout [53], creating the funnel effect. In some embodiments, grippable spout [53] may be angled at or around 37 at the opening [52], as in exemplary angle [55] in FIG. 2. The preferred dimensions of the dispensing funnel can be adjusted to suit different bag sizes, but the angle of curvature must increase from the opening [52] to side seam [4]. The dimensions are applicable to any size of bag, in other words, the length and height of the bag can be longer or shorter without deviating from the spirit of the invention.

[0019] The opening [52] can be manufactured sealed for a user to cut or open, or it can be manufactured without sealing. In some embodiments the opening may comprise a resealable opening such as a zipper opening [19], as depicted in FIG. 5. In some embodiments, the end user can cut the opening [52] at any desired section of the grippable spout [53] to vary the speed of the flow, such as to make the spout conducive to the specific contents in the bag. The dispensing funnel can also be detachable from the bag, for instance by means of a press-and-seal zipper closure [56]. The separate closure enables the user to release only the amount of contents necessary into the dispensing funnel, before pouring. In some embodiments the dispensing funnel also comprises measuring markers [57] to enable the user to measure the contents released into the dispensing funnel.

[0020] In some embodiments, the bag is an empty product sold directly to consumers as an openable and reusable bag for different contents. For instance, the embodiment depicted in FIG. 1 comprises a zipper closure [9] at top end [2], while the embodiment depicted in FIG. 5 comprises a zipper closure at back end. In other embodiments, the bag can be sealed and sold pre-filled with contents directly to consumers. For instance, the embodiment depicted in FIG. 3 is filled with contents and heat sealed at the back end. No part of the bagaside from the grippable spoutmust necessarily be openable by consumers, and pre-filled bags can be filled from any edge and sealed without departing from the spirit of the invention. Furthermore, any means of opening and closing may be added to the bag, including press and seal zippers, Velcro closure, clips, etc. . . .

[0021] Because the bag is made of two flexible sheets, it is easily manufacturable by die-cutting along the edges. Heat sealing can be applied along any desired edges. Because the bag is comprised of a rectangular shape with the dispensing funnel protruding from one end of one side of the bag, it is particularly conducive to cutting mirror images, thus saving waste. Another method of manufacture is to cut a single sheet that is folded in two to make one bag, and heat sealing the edges as desired. The flexible sheets comprising the bag can be made of any material and be of any thickness. For instance, the bag may be produced of fabric, paper, polypropylene, polyurethane, vinyl, polyester, cellophane, etc. . . . and may be sealed by any method such as stapling or glue.

[0022] The bag with dispensing funnel enables a user to hold the bag on its horizontal side and grip the dispensing spout with their other hand, enabling tilting the bag in order to let contents flow. Thus the bag with dispensing funnel enables a user to stand and pour contents from the bag without bending over. To further facilitate lifting and holding the bag while standing vertically, some embodiments of the bag comprise handles or straps to provide added comfort or support. For instance, the embodiment depicted in FIG. 4 comprises a strap [12] to hold the bag from the shoulder. This is particularly useful for heavy contents such as ice melt and cat litter. The embodiment depicted in FIG. 4 also comprises a grip [8] to facilitate moving and transporting the bag. Grip [8] also gives the user more control over the bag and hence the pour. In some embodiments, an additional heat sealing line [13] may be included under the handle [8], providing more support by distributing weight laterally along the bag.

[0023] It should be noted that all of the descriptions contained herein are of the best currently contemplated modes of carrying out exemplary embodiments of the invention. They are not to be taken in a limiting sense, but are made merely for the purpose of illustrating the general principles of the present invention.
