Description

BACKGROUND OF THE INVENTION

[0001] This invention relates to a method and device for holding a flexible bag of various sizes in an open manner in order to facilitate its filling.

[0002] Bags such as refuse bags, shopping bags etc., used for collecting and holding objects are commonly made of flexible material such as plastics, fabric, other synthetics, or paper. They are normally used for holding objects either for easy transportation, storage, or disposal. The most annoying problem in using a flexible bag is to maintain it in an open manner for filling, since it is awkward for a user to open the bag with one hand while filling it with the other. For example, when using a flexible refuse bag outdoor for collecting leaves in the fall, the flexible bag would be fluttered by wind which makes maintaining the bag in the open condition extremely difficult. Even indoor, it is inefficient and troublesome to maintain the bag opened with one hand and to fill it with the other only free hand.

[0003] Many devices have been developed to alleviate the above problem. One common device is in the form of a fixed bracket designed to match the size of the bag or slightly larger thereof, and the flexible bag may be mounted by stretching its lip portion to wrap tightly over the bracket. The stretch tension of the bag material would maintain the bag in the open manner. With this device, the bracket must have a relatively larger dimension than the lip portion of the bag for creating the stretch tension strong enough to hold the bag mounted in the open manner. Often times, the lip portion of the bag would be torn when the user attempts to stretch it to wrap over the bracket. Furthermore, in use, the weight of the load in the bag would simply pull the bag off from the bracket. The latter problem may be mitigated by using a container having a comparable size as the bag. It may be placed within the container with its lip portion again stretched and wrapped tightly around the upper opened rim portion of the container so that the container would support the weight of the loaded bag. However, the bulkiness of the container makes it difficult for carrying around. The container would occupy storage space, and the lip portion of the bag is still subject to the tearing problem. It is also difficult to remove the bag from the container for disposal, and therefore, it limits the benefits of using flexible bags.

[0004] The above problems have been alleviated by the devices shown in U.S. patent application Ser. No. 09/532,313 filed on Mar. 22, 2000 by the Applicant of the present application. Nevertheless, due to the lack of standards, there is a large variation of flexible bag sizes; and no single mounting device presently would work satisfactorily with such wide range of flexible bag sizes. However, this invention is aiming to overcome this problem.

SUMMARY OF THE INVENTION

[0005] The principal object of the present invention is to provide a device with a plurality of inner hoops for mounting a flexible bag of a wide range of sizes.

[0006] It is another object of the present invention to provide a mounting device having means for accommodating excess lip portion of the bag when the bag is larger than the mounting device for facilitating is mounting operation.

[0007] It is yet another object of the present invention to provide a spillage collect tray adapted for use with the mounting device for capturing spillage of debris or liquid from the mounted bag in the event a bag puncture.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0034] Referring more particularly to the drawings, the basic principle of the present invention is generally shown in FIGS. 1 and 2. The basic components of the device comprises of an outer binder 10 having an inner side wall 11 and an inner hoop 12 having an outer side wall 13. The surface of the inner side wall 11 of the outer binder 10 and outer side wall 13 of the inner hoop 12 have complementary mating shapes. As shown in FIG. 1, both of these side walls 11 and 13 have complementary slopes of one another such that when the inner hoop 12 is located within the outer binder 10, they will engage and mate with one another intimately. A sloping shape is shown as an example for ease of illustration, it will be appreciated by those skilled in the art that the surface of the side walls 11 and 13 may have other shapes or configuration; and as long as they are complementary to one another they will mate with one another to form the basic device for providing the desired result of the present invention for mounting a flexible bag.

[0035] A flexible bag 14 may be mounted to the device as shown in FIG. 2 with the flexible bag 14 first inserted through the opening of the inner hoop 12 and then with the bag's lip portion 15 folded backwards to wrap over the outer side wall 13 of the inner hoop 12. The inner hoop 12 with the flexible bag 14 thus mounted thereon is then placed into the outer binder 10 to sandwich the bag's folded lip portion 15 between the mating inner side wall 11 of the outer binder 10 and the outer side wall 13 of the inner hoop 12. The device would thus maintain the flexible bag 14 in the open manner for filling a load 14A into the bag. The weight of the load 14A will inherently exert a pulling force downwards to the inner hoop 12 to cause it to engage tightly with the outer binder 10. As the bag is being filled, the increasing weight of the load 14A will correspondingly exert an increasing force to grasp the bag's lip portion ever more tightly between the mating side walls of the outer binder 10 and the inner hoop 12.

[0036] FIGS. 3 shows another basic concept of the present invention, in which a plurality of inner hoops 12A through 12E may be provided within the outer binder 10. The inner hoops 12A through 12E have gradually decreasing sizes such that a flexible bag of any size may be mounted between the outer binder 10 and the inner hoop 12A or between any neighboring pairs of inner hoops selectively or between the outer binder 10 and any selected one of the inner hoops 12A to 12E. However, in practice, since the size variation between the neighboring inner hoops is small whereas the variation of size between common flexible bags is usually relatively large, it is not practical to provide such large number of inner hoops with relatively small gradually decreasing sizes.

[0037] FIG. 4 shows a more practical approach for mitigating the drawback of the above device. In this construction, the inner hoops 12F through 12J are in the form of narrow annular hoops of rapidly decreasing sizes. The inner hoops 12F through 12J will thus engage a portion of the outer binder 10 as best shown in FIG. 5. Thus, the number of inner hoops required is greatly and practically reduced to accommodate the same range of available common flexible bags than the device in FIG. 3. Generally, only two inner hoops such as 12I and 12G will suffice to cover the common different flexible sizes as shown in FIGS. 6, 7, 8 and 9. The lower inner hoop 12I may lie completely within the outer binder 10 as shown in FIG. 7, or a lower portion of it may extend outside below the bottom edge of the outer binder 10 as shown in FIG. 9.

[0038] FIG. 10 shows that the outer binder 10 may be provided with an integral bracket 16 having extension lugs 17 for mounting the device in a cantilever manner horizontally at a fixed location on a vertical wall. Alternatively, FIG. 11 shows that the outer binder may be integrally formed in the top of a portable stool or table 18 having supporting legs 19 so that the device may be moved freely to any selected convenient location. FIG. 12 shows that a circular lid 20 may be provided at the top 21 of the stool or table to cover the opening of the outer binder. The lid 20 may lie flush with the top 21 or it may recede completely within the opening. A central opening 22 is formed in the lid 20 so that waste material may be placed into the flexible bag mounted on the device without having to open or remove the lid.

[0039] FIGS. 13 and 14 illustrate an alternative embodiment in which the mating side walls of the outer binder and the inner hoop have mating shapes other than sloping side walls. The outer binder 10A is a thin or narrow hoop having an inner annular shoulder portion 23. A plurality of thin inner hoops 12K through 12O are provided. The inner hoops are of decreasing sizes; and each inner hoop has an outer annular flange 24 and an inner annular shoulder 25. The first inner hoop 12K may engage within the outer binder 10A with its outer annular flange 24 resting on the inner annular shoulder portion 23 of the outer binder 10A. Each subsequent inner hoop may engage with the neighboring larger size inner hoop with its outer annular flange resting on the inner annular shoulder of the latter. In this latter case, the larger inner hoop serves as an extension of the outer binder. The last smallest inner hoop 12O is not necessary to be provided with an inner annular shoulder since no further inner hoop will engage within it. In this embodiment, the engagement between the largest inner hoop 12K with the outer binder 10A and between any neighboring inner hoops is not required to have a tight fitting.; as long as the outer annular flange 24 of the largest or intermediate inner hoop has a width large enough such that it will rest on the inner annular shoulder portion 23 of the outer binder 10A or the neighboring larger inner hoop, the weight of the waste material in the flexible bag would exert the required force to pull the inner hoop against the outer binder or another neighboring inner hoop to clamp the flexible bag securely in place. FIG. 15 shows the embodiment of FIGS. 13 and 14 formed integrally into a stool or table similar to the embodiment shown in FIG. 12. Open ended slots 26, 27, 28 and 28A may be formed around the annular flange 24 as shown in FIG. 13 to facilitate the mounting of the flexible bag during the mounting operation. This is achieved by pushing various spots around the fold back lip portion of the flexible bag into these opened end slots to be held therein so that the inner hoop with the flexible bag thus mounted thereto may be placed easily inside the outer hinder.

[0040] Another embodiment is shown in FIGS. 16 and 17. In this embodiment, the outer binder 10B has a step-like inner side wall surface 11A and the inner hoops 12P through 12T of increasing sizes have an annular outer flange 24 adapted to engage with the annular steps at the different levels of the inner side wall surface 11A of the outer binder 10B. Similar to the previous embodiment, the inner hoops and the outer binder in this embodiment are not required to have a tight engagement. The weight of the waste material in the flexible bag would also exert the required force to pull the inner hoop against the outer binder to sandwich the lip portion of the flexible bag tightly between them. A wall mounted device having this embodiment incorporated therein is shown in FIGS. 18 and 19. Only two selected inner hoops 12P and 12S are provided to cover commonly available different sizes of flexible bags.

[0041] A plurality of retaining openings 29 are formed over the entire sloping side wall of the inner hoops as shown in FIG. 20 and FIG. 21 These retaining openings 29 preferably have a star shape and they are adapted for facilitating the mounting of the flexible bag to the present device. The flexible bag is first inserted through the inner hoop as discussed above with its lip portion folded backward over the inner hoop and selected parts of the folded back lip portion may be pushed through those retaining openings around the inner hoop so that these pushed through parts are gripped by the retaining openings. The inner hoop with the flexible bag thus mounted thereto may then be easily placed within the outer binder to sandwich the folded back lip portion of the flexible bag between them.

[0042] A portable embodiment of the present device is shown in FIGS. 22 and 23. In this embodiment, the outer binder 10C has a flat base 30 and an arch shaped upper binder 31. The upper binder 31 has an inwardly sloping inner side wall 32. The inner hoops 12U and 12V have the same shape as the outer binder 10C and have a flat base 33 and a narrow upper arch portion 34 which has a sloping outer side wall 35 adapted to mate intimately with the inner side wall 32 of the outer binder 10C. The inner hoops may engage within the outer binder as shown in FIG. 23 similar to the circular embodiments as shown above for mounting a flexible bag between the outer binder and the larger inner hoop. Only a portion of the side wall of the inner hoop and the outer binder need to engage with each other to achieve the clamping function for the flexible bag. In the same fashion, the smaller inner hoop 12V engages with the adjacent larger inner hoop 12U. The device may be conveniently placed anywhere on a floor by the flat base 30. Also, the flat base 30 may serve as a dust pan to facilitate sweeping of the waste material into the flexible bag mounted thereto.

[0043] Another portable embodiment of the present device is shown in FIGS. 24 and 25. The arch-shaped outer binder 10C is provided with a step inside shoulder 36 and the arch portion of an inner hoop 12W is provided with a flanged shoulder 37 as well as an inside shoulder 37A and a second inner hoop 12X having just a flange should 37 such that the flexible bag may be mounted either between the outer binder 10C and the largest inner hoop 12W, or between the largest inner hoop 12W and the smaller inner hoop 12X similar to the annular shape embodiment as shown previously.

[0044] A preferred portable embodiment having all the features of the present invention is best shown in FIG. 26. In this embodiment, the outer binder 10D is a generally triangular hoop or band having a base portion 38 and two sloping upper side walls 39 and 40. A substantially U-shaped handle 41 is located at the apex between the upper side walls 39 and 40 such that the device may be conveniently carried from one location to another. The handle 41 has a closed front wall 42 which is provided with a through opening 43 adapted for hanging the device on a wall for storage. The side walls 39 and 40 have an inwardly and rearwardly sloping inner surface and a plurality of elongated transverse slot openings 44 and 45 are formed on the side walls 39 and 40 respectively. Two spaced supporting extension legs 46 and 47 extend outwardly and rearwardly adjacent to the corners of the base portion 38 to enhance the secure resting of the device on the floor. A plurality of screw openings 48 are formed on the inner surface of the base portion 38. Two semi-circular latches 49 and 50 are formed at the rear edge portion of the base portion 38. Two cut outs 51 and 52 are formed on the rear edge portion of the side walls 39 and 40 respectively preferably adjacent to the two lower corners. The inner hoop 12Y is generally triangular in shaped and having a size adapted to engage within the outer binder 10D.

[0045] The narrow inner hoop 12Y has a flat base portion 53 and two slanting side walls 54 and 55 which have an outer surface sloping inwardly and rearwardly such that the inner hoop 12Y may engage intimately within the outer binder 10D for mounting the flexible bag between them. A plurality of star shaped retaining openings 56 and 57 are formed in the side walls 54 and 55 respectively. The second set of retainer openings 62 is formed at the base portion 53 of the inner hoop 12Y. The combination of the retainer openings 56 and 57 and 62 achieve the same effect as shown in FIGS. 20 and 21 such that the lip of the flexible bag clings to the inner hoop 12Y to ease its insertion into the outer binder 10D. These retaining openings 56 and 57 will aligned with the elongated slot openings 44 and 45 respectively. The inner hoop 12Y may be released from the outer binder 10D by inserting fingers into the openings 56 and 57 through the longer openings 44 and 45 to push the inner hoop 12Y outwards.

[0046] Two semi-circular latches 58 and 59 are formed at the rear edge portion of the side walls 54 and 55 respectively adjacent to the lower two corners therein. Two cut outs 60 and 61 are formed at the rear edge portion of the base portion 53 and located adjacent to the two lower corners. The retaining opening 62 will align with the screw openings 48 formed on the base portion 38 of the outer binder 10D when the inner hoop 12Y is fitted within the outer binder 10D. The semi-circular latches 58 and 59 of the inner hoop 12Y will also engage with the cut outs 51 and 52 of the outer binder to prevent the inner hoop 12Y from being pulled out from the rear of the device by the weight of the loaded bag. The semi-circular latches 49 and 50 on the base portion of the outer binder 10D will also engage with the cut outs 60 and 61 at the rear edge portion of the inner hoop 12Y to prevent the inner hoop 12Y in falling out from the front of the device when the device is resting on a sloping floor. Thus, the inner hoop 12Y is fitted within the outer binder 10D securely by the latches.

[0047] The portable device described in FIG. 26 with the outer binder 10D and the inner hoop 12Y can readily be converted into a fixed mount device. The outer binder can be secured with screws to a wall or post at the openings 48. The retainer openings 62 of the inner hoop 12Y are larger and are strategically centered such that the inner hoop 12Y can be moved in and out of the outer binder 10D without the obstructions from the heads of the screws located at the screw openings 48.

[0048] Although the present invention has been described with reference to particular embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.
