The field of the present invention generally relates to polymeric storage bags and, more particularly, to polymeric storage bags having or capable of having multiple compartments.
Polymeric bags or pouches are very popular household items that are used in a variety of applications, including storage of food and the like. The addition of reclosable fasteners or closures to these bags further enhanced their utility. One such reclosable fastener is a “zipper” that includes complementary first and second profiles that releasably engage each other to close and open the polymeric bag. The profiles are simply pressed until they snap together to close the bag and pulled until they snap apart to open the bag. The addition of sliders to these zipper-type fasteners made the fasteners even easier to open and close because simply sliding the slider in one direction closes the bag and sliding the slider in the other direction opens the bag.
Polymeric storage bags or pouches are available in a wide variety of sizes and configurations. Often more than one bag must be used when more than one type of item needs to be stored. One solution was to provide polymeric storage bags having multiple compartments. While these polymeric storage bags may be useful in some specific applications, they are not very versatile. Thus, these polymeric storage bags or pouches can cause a need to purchase and store an even greater number of different types and/or configurations of polymeric storage bags or pouches. Accordingly, there is a need for improved polymeric storage bags or pouches.
Disclosed are polymeric bags or pouches that are convertible between different quantities of storage compartments to overcome at least one of the disadvantages of the prior art. Disclosed is a flexible polymeric pouch comprising, in combination, first and second walls in opposed relationship to form a storage space therebetween and having lateral sides, a top, and a bottom opposed to the top, a first closure disposed on at least one of the first and second walls near the top, and a second closure disposed on the first and second walls between the first closure and the bottom. The first and second closures are spaced apart a sufficient distance to permit a user to independently open and close the first and second closures. The second closure is reclosable so that the second closure is opened and closed to selectively divide the storage space into separate first and second storage compartments.
Also disclosed is a flexible polymeric pouch comprising, in combination, first and second walls in opposed relationship to form a storage space therebetween and having lateral sides, a top, and a bottom opposed to the top, a first closure disposed on at least one of the first and second walls near the top, and a second closure disposed on inner sides of the first and second walls between the first closure and the bottom. The second closure is a reclosable closure and includes complementary first and second profiles that releasably engage each other to selectively open and close the second closure. The first and second closures are spaced apart a sufficient distance to permit a user to independently open and close the first and second closures. The second closure is opened and closed to selectively divide the storage space into separate first and second storage compartments.

The following detailed discussion of various alternative and preferred embodiments will illustrate the general principles of the invention with regard to specific embodiments. Other embodiments of the present invention suitable for other applications will be apparent to those skilled in the art given the benefit of this disclosure.
Referring now to the drawings,
The illustrated pouch 10 also includes first and second closures 30, 32 disposed on inner sides of the pouch walls 14, 16. The first closure 30 is located near the top opening 24 and is disposed between the second closure 32 and an upper edge of the top portion 26. The illustrated first closure 30 is a reclosable closure in the form of a zipper having complementary first and second profiles 30a, 30b that releasably engage each other to selectively open and close the first closure 30. The zipper style first closure 30 and/or the profiles 30a, 30b can have any suitable configuration and can have more than one track. When the first closure 30 is located at the top edge of the top portion 26, the first closure 30 can be configured with a slider for easy opening and closing of the first closure See U.S. Pat. Nos. 8,529,129, 8,469,593, 8,376,614, 8,272,107, 8,245,364, 8,192,085, 8,176,604, 8,061,898, 7,946,766, 7,886,412, 7,857,515, 7,850,368, 7,784,160, 7,585,111, 7,574,781, 7,506,416, 7,461,434, 7,410,298, 7,364,361, 7,270.479, 7,188,394, D527,683, 7,052,181, D519,368, D490,706, D422,909, 6,021,557, 5,836,056, and 5,809,621, for examples of reclosable zippers and/or sliders, the disclosures of which are expressly incorporated herein in their entireties by reference. It is noted that the first closure 30 can alternatively be any other suitable type of closure or reclosable closure.
The second closure 32 is located below the first closure 30 and is disposed between the first closure 30 and a lower edge of the bottom portion 22. The illustrated second closure 32 is also a reclosable closure in the form of a zipper having complementary first and second profiles 32a, 32b that releasably engage each other to selectively open and close the second closure 32. The zipper style second closure 32 and/or the profiles 32a, 32b can have any suitable configuration. It is noted that the second closure 32 can alternatively be any other suitable type of reclosable closure.
The illustrated second closure 32 is parallel to the first closure 30 and the two closures 30, 32 are vertically spaced from one another by a distance that is sufficiently large so that that the closures 30, 32 act as separate and independent closures. In addition, the closures 30, 32 are disposed sufficiently far apart to form a suitable storage compartment 12a therebetween. Typically, these results are accomplished by spacing the closures 30, 32 at least about 1 inch (2.54 mm) apart, and more preferably, at least about 2 inches (5.08 mm) apart, and most preferably at least about 3 inches (7.62 mm) apart, although a different spacing may instead be used.
The first closure 30 can exhibit a first closure characteristic and the second closure 32 can exhibit a second closure characteristic different than the first closure characteristic. For example, the second closure 32 may exhibit a relatively low level of resistance to closure opening forces and/or provide a relatively high level of deformation so as to exhibit a clicking feel and/or sound when the closure 32 is opened or closed.
Because the illustrated first and second closures 30, 32 are spaced apart a sufficient distance to permit a user to independently open and close the first and second closures 30, 32, the pouch 10 is convertible between a first configuration wherein the first closure 30 is closed and the second closure 32 is open so that the storage space 28 provides a single storage compartment 12 and a second configuration wherein both the first and second closures 30, 32 are closed so that the storage space is divided into separate first or upper and second or lower storage compartments 12a, 12b by the second closure 32. Thus the second closure 32 is opened and closed to selectively divide the single storage compartment 12 of the storage space 28 into the separate first and second storage compartments 12a, 12b. The illustrated first or upper and second or lower storage compartments 12a, 12b are each horizontally extending storage compartments located one above the other and are configured to be the same size. It is noted that the storage compartments 12a, 12b can alternatively be configured to have different sizes.
Any of the features or attributes of the above described embodiments and variations can be used in any combination with any of the other features and attributes of the above described embodiments and variations as desired.
It is apparent from the forgoing disclosure and detailed description that the present invention provides polymeric bags or pouches 10, 100, 200, 300, 400, 500, 600 that can be easily converted between different storage configurations. For the two closure embodiments, the second closure 32 can remain open so that items can be stored in the entire storage space 28 or the second closure 32 can be closed so that different items can be stored in the separate storage compartments 12a, 12b formed by the second closure 32. For example, chips, vegetables, or the like could be stored in the first storage compartment 12a while dip is stored in the second storage compartment 12b. Also for example, a sandwich can be stored in the first storage compartment 12a while a condiment (or condiments when subdivided) can be stored in the second storage compartment 12b. It is also apparent that the present invention can be utilized to separately store an item in the separate storage compartments 12a, 12b and mixed at the time of use within the entire storage space 28 (or a combination of storage compartments if there are more than two). For example, a first item like lettuce and/or other salad components can be stored in the first storage compartment 12b while a second item to be mixed with the first item like salad dressing can be separately stored in the second storage compartment 12b. When it is time to mix the first and second items, the second closure 32 is opened, while the first closure 30 remains closed, so that the first and second items can be mixed by shaking the pouch 10 while the first closure 30 remains closed. The mixed first and second items can then be removed from the pouch 10 by opening the first closure 30.
From the foregoing disclosure and detailed description of certain preferred embodiments, it is also apparent that various modifications, additions and other alternative embodiments are possible without departing from the true scope and spirit of the present invention. The embodiments discussed were chosen and described to provide the best illustration of the principles of the present invention and its practical application to thereby enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the present invention as determined by the appended claims when interpreted in accordance with the benefit to which they are fairly, legally, and equitably entitled.
This application claims the priority benefit of U.S. Provisional Patent Application No. 61/895,144 filed on Oct. 24, 2013, the disclosure of which is expressly incorporated herein by reference in its entirety.
