DETAILED DESCRIPTION
When children travel with their toys, they often lose them or do not have a place to play with their toys at their destination. An innovative convertible toy container that unzips and converts to an activity mat (e.g. play mat) provides children with both a way to carry their toys and a place to play. Decorating this convertible container (e.g. storage container) in the theme of toys (e.g., car, model runway, automobile themes, truck race track) makes the container even more attractive and fun for the children. Cleaning up toys is also inconvenient and causes unwanted discussions between caregivers and children. To this end, the activity mat can be zipped up into the container and collect the toys in the process, thereby eliminating the need for these discussions. The container can take the shape of, for example, a circular box, a square box, a rectangular box, a car, a truce a log, a car wheel, etc. It is contemplated that the convertible container can be formed in various other shapes in accordance with the present disclosure. The container can be made of any material including, but not limited to, cotton, canvas, hemp, nylon, polyester, or similar materials or combinations thereof. The inner stiffening material that provides rigidity to the structures of the container can be made of any sturdy or semi-rigid material such as cardboard, paperboard, plastic, foam, PVC, or other material known in the art. Optional padding may further line the interior of the container, and may include material composed of foam, wadding, or other materials known in the art.
The decoration of the inside and the outside of the activity mat can be by embroidery, sewing on fabric accessories. The decoration can also be made with silk screening, rotogravure, heat transfer, painting or other methods of decoration known in the art.
Referring to FIGS. 1-4, according to certain embodiments, an apparatus convertible between a storage container and an activity mat, also referred to as a convertible container 100, is depicted in the general shape of a hat-box, as shown in FIG. 1. The convertible container 100 includes a generally circular lid 110 (which may be oval, round), a generally circular base 120, a wall 130, and two zipper pulls 140a,b. Both the lid 110 and the base 120 have zipper teeth 112, 122 arranged about their respective peripheries. The wall 130 has zipper teeth 132 arranged to mate with the corresponding zipper teeth 112 and 122 on the lid 110 and on the base 120, respectively. According to certain embodiments, as shown in FIG. 1, the two zipper pulls 140a,b are adapted to removably connect the zipper teeth 132 on the wall 130 with the corresponding zipper teeth 112 and 122 on the lid 110 and on the base 120, respectively, such that the lid 110 and the base 120 are zippered to the wall 130 in the storage container configuration.
The wall 130 has a generally rectangular shape having two opposing longer edges 133 and two opposing shorter edges 135. The convertible container 100 is shown as a generally cylindrical shape; however, it is contemplated that in certain embodiments a convertible container can be of a variety of shapes including, but not limited to, a circular box, a square box, a rectangular box, a car, a truck, a car wheel, etc.
Referring to FIG. 2, the convertible container 100 of FIG. 1 is shown with the lid 110 unzipped in an open, flattened configuration, also called an activity mat configuration. The lid 110 can be unzipped for access to toys and other household goods stored within the convertible container 100. Storage pockets 116 and 126 are attached to an interior portion of the lid 110 and the base 120, respectively. The storage pockets 116 and 126 can be used to store and/or organize toys or household goods (e.g. cars, dolls, crayons, figurines, etc.) and further to prevent the toys from shifting around and breaking when transporting the convertible container 100. It is contemplated that in certain embodiments a convertible storage container 100 is provided with only storage pockets on a lid or on a base. It is also contemplated a convertible container is provided without any storage pockets, or alternatively storage pockets may be formed on an interior or exterior surface of a wall. According to certain embodiments, a raised track 138 is attached to an interior portion of the wall 130. The raised track 138 may be used as a race track for racing cars when the convertible container 100 is arranged in the activity mat configuration, shown in FIGS. 3 and 4. It is contemplated that in certain embodiments, additional tracks and/or convertible containers may be adaptable to attach to the activity mat to extend the raised race track 138.
Referring to FIGS. 3 and 4, the convertible container 100 of FIGS. 1 and 2 is shown in the activity mat configuration. According to certain embodiments, when the lid 110 and the base 120 are unzippered from the wall 130, the convertible container 100 can lie substantially flat as an activity mat, as shown in FIG. 4. The inner surfaces of the lid 110, the base 120, and the wall 130 form an activity mat surface. The activity mat 100 may be decorated with a theme appropriate for a suggested usage of the convertible container 100. For example, a child may use the convertible container 100 to store dolls, and so a dollhouse theme with a model runway can be decorated on the inner surfaces of the convertible container 100. For another example, a child may use the convertible container 100 to store toy cars and trucks, and so a race track theme including racing tracks may be decorated or incorporated on the inner surfaces of the convertible container 100. FIG. 3 depicts one example of how the convertible container 100, in the activity mat configuration, may be setup to form a race track having an integrated slope. A child may easily set one end of the wall 130 and the lid 100 or the base 120 on top of a box or chest to create a fun and exciting sloped track for racing cars.
In certain embodiments, the convertible container of FIGS. 1-4 also includes a first and a second attachment member 150a,b. The first attachment member 150a permanently connects the lid 110 to the wall 130 (e.g., by stitching, glue, or the like). The second attachment member 150b permanently connects the base 120 to the wall 130. The attachment members 150a,b generally connect the lid 110 and the base 120 tangentially to the wall 130. The attachment members 150a,b have a generally rectangular shape and can be made from any material including, but not limited to, cotton, canvas, hemp, nylon, polyester, polypropylene, or similar materials or combinations thereof. The attachment members 150a,b can have a length between four inches and a quarter of an inch. Desirably, the attachment members 150a,b have a length between two inches and one inch. The attachment members 150a,b can have a width between a tenth of an inch and one inch. Desirably, the attachment members 150a,b have a width between a quarter of an inch and one inch. It is contemplated that in certain embodiments, the lid 110 and/or the base 120 are not attached to the wall 130 by an attachment member such that the lid 110 and/or the base 120 may be completely detached from the wall 130 when unzippered therefrom.
Referring to FIG. 4, according to certain embodiments, the convertible container 100 includes the first attachment member 150a to connect the lid 110 to one of the two opposing longer edges 133a of the wall 130 and the second attachment member 150b to connect the base 120 to the other opposing longer edge 133b of the wall. The lid 110 and the base 120 are attached to the wall such that they resemble a percent sign (%) configuration. It is contemplated that in certain embodiments, the lid 110 and the base 120 can be attached to the wall 130 at different locations along the two opposing longer edges 133a,b. For example, as depicted in FIG. 6, the lid 210 and the base 220 can be connected to the wall 230 at substantially the same point on the two opposing longer edges 233a,b of the wall 230. It is further contemplated that the lid 210 and the base 220 can be connected at a middle portion of the two opposing longer edges 233a,b of the wall or the lid 210 and the base 220 can be connected near the same or opposing shorter edges 235 of the wall 230.
Referring back to FIGS. 1-4, the zipper pulls 140a and 140b can be configured to zip and unzip in the opposite directions relative to one another (i.e. one clockwise and the other counterclockwise). It is contemplated that in certain embodiments, the zipper pulls 140a,b can be configured to zip and unzip in the same direction (i.e. both clockwise or both counterclockwise).
According to certain embodiments, one of the two opposing shorter edges 135 of the wall 130 substantially overlaps the other opposing shorter edge 135 of the wall 130. The wall 130 can also include hook fasteners 139 near one of the two opposing shorter edges 135 of the wall 130 and loop fasteners on the other opposing shorter edge 135 of the wall 130. The hook and look fasteners (e.g. VELCRO®) are removably attachable to one another. When the two zipper pulls 140a,b urge the activity mat into the convertible container 100 configuration, the one of the two opposing shorter edges 135 containing the loop fasteners 139 is also urged to overlap the other opposing shorter edge 135 containing the hook fasteners 139, thereby removably attaching the wall 130 to itself. Note that the length of the wall 130 is at least equal to the circumference of the lid 110. To allow for the overlapping attachment mechanisms, such as the hook and loop fasteners, the length of the wall 130 is longer than the circumference of the lid 110. The lid 110 and the base 120 have substantially the same dimensions such that when the convertible container 100 is in a folded configuration (as shown in FIG. 1), the convertible container 100 has a generally cylindrical shape. Sometimes, this shape is referred to herein as a “hat box” shape.
According to certain embodiments, the convertible container 100 can also include a handle 116, as shown in FIG. 1. It is contemplated that the handle 116 can be attached to the lid 110, the base 120, or the wall 130. The handle 116 can be made of any material including, but not limited to, cotton, canvas, hemp, nylon, polyester, or similar materials or combinations thereof. The user grasps the handle 116 for conveniently carrying the convertible container 100.
According to certain embodiments a convertible container includes a lid, a base, a wall, and at least one zipper. Note that the lid, base, and wall may be formed of an integral piece of material, and the designations simply refer to those portions of the material that correspond to a lid, a base, and a wall. Alternately, any combination of the lid, base, and wall may be separate pieces attached together by, for example, stitching, glue, or other techniques well known in the art. When the convertible container is in the zippered-up, folded configuration (such as shown in FIG. 1), the convertible container resembles a wheel and may decorated accordingly complete with tread marks on the wall and a hubcap and brake pad on the lid to complete the theme. The lid 202 can include a convenient handle for transporting the wheel-themed convertible container. Zipper pulls and zipper teeth are included and attached just like in the convertible container 100 described above. Hook and loop fasteners are attached to the ends of the wall to fasten the ends when the base or the lid is zippered to the wall.
Referring to FIGS. 5-6, according to certain embodiments, an apparatus convertible between a storage container and an activity mat, also referred to as a convertible container 200, is depicted in the shape of a hat-box, as shown in FIG. 5. The convertible container 200 is similar to the convertible container 100 shown in FIGS. 1-4 and described above in that the convertible container 200 includes a lid 210, a base 220, and a wall 230; however, the convertible container 200 also includes four zipper pulls 240a,b,c,d as compared to the two zipper pulls 140a,b included in the convertible container 100. The four zipper pulls 240a,b,c,d are adapted to removably connect zipper teeth 232 on the wall 230 with corresponding zipper teeth 212 and 222 on the lid 210 and on the base 220, respectively, such that the lid 210 and the base 220 are zippered to the wall 230 in the storage container configuration. The lid 210 has two zipper pulls 240a,b and the base 220 has the other two zipper pulls 240c,d. The convertible storage container 200 can further include a handle 216 that is attached to lid 210 as shown, or alternatively, a handle can be attached to either the base 220, the wall 230.
Referring to FIG. 6, the convertible container 200 of FIG. 5 is shown in the unzippered activity mat configuration. The activity mat configuration of convertible container 200, as shown in FIG. 6, resembles a mathematical divide sign, where the lid 210 and the base 220 are permanently attached via attachment members 250a,b near the center portion of the wall 230.
Referring to FIGS. 7 and 8, according to certain embodiments, an apparatus convertible between a storage container and an activity mat also referred to as a convertible container 300, is depicted in the shape of an elongated cylinder, as shown in FIG. 7. The convertible container 300 is similar to the convertible container 100 shown in FIGS. 1-4 and described above in that the convertible container 300 includes a lid 310, a base 320, a wall 330, and two zipper pulls 340a,b. The zipper pulls 340a,b, are configured to removably connect zipper teeth 332 on the wall 330 with corresponding zipper teeth 312 and 322 on the lid 310 and on the base 320, respectively, such that the lid 310 and the base 320 are zippered to the wall 330 in the storage container configuration. However, the zipper pull 340b is also configured to removably connect zipper teeth 337 that run along each of the two opposing shorter edges 335 of the wall 330. The ability of the zipper pull 340b to additionally connect the two opposing shorter edges 335 of the wall 330 eliminates the need for overlapping wall edges and Velcro type fasteners described above in relation to the convertible containers 100 and 200. The convertible storage container 300 can further include a handle 316 that is attached to lid 310 as shown in FIG. 7, or alternatively, a handle can be attached to either the base 320, the wall 330.
Referring to FIG. 8, the convertible container 300 of FIG. 7 is shown in the unzippered activity mat configuration. The lid 310 and the base 320 are permanently attached via attachment members 350a,b near one of the two opposing shorter edges 335 of the wall 330.
Referring to FIG. 9, a schematic example of a convertible container 400 is shown in the activity mat configuration. The convertible container 400 is similar to the convertible container 300, but the convertible container 400 only includes one zipper pull 440 that is configured to zip and unzip all of the zipper teeth arranged around a lid 410, a base 420, and a wall 430 to transform the convertible container 400 between the activity mat configuration and the storage container configuration. The arrows A-K indicate an exemplary path that the zipper pull 440 takes to completely transform the activity mat configuration to the storage container configuration.
Referring to FIG. 10, a schematic example of a convertible container 500 is shown in the activity mat configuration. The convertible container 500 is similar to the convertible container 100 and 300, but the convertible container 500 only includes one zipper pull 540 that is configured to zip and unzip all of the zipper teeth arranged around a lid 510, a base 520, and a wall 530 to transform the convertible container 500 between the activity mat configuration and the storage container configuration. The arrows A-K indicate an exemplary path that the zipper pull 540 takes to completely transform the activity mat configuration to the storage container configuration. Thus, a convertible container may only include one zipper pull in either a percent sign configuration (e.g., container 500) or a configuration shown in FIG. 9 (e.g., container 400).
Referring to FIGS. 11-20, according to certain embodiments a convertible container 600 is shown. The convertible container 600 is adapted to transform between a storage container configuration and an activity mat configuration. The convertible container 600 includes a base portion 610, two side portions 630, a lid flap 620, and two zipper pulls 640. The two side portions 630 are connected to the base portion 610. Each of the two side portions 630 has zipper teeth 612. The side portions 630 are generally symmetrical, but it is contemplated that the side portions 630 can be asymmetrical. The lid flap portion 620 is connected to the base portion 610 and is adjacent to the two side portions 630. The lid flap portion 620 also has zipper teeth 612 The two zipper pulls 640 are configured to zip and unzip the lid flap portion 620 to and from the two side portions 630. As mentioned above, the base portion 610, side portions 630, and lid flap 620 may be formed integrally of a single piece of material, with the various portions delineated by stitching or seams as shown by the dashed lines in FIG. 14, for example. The stitching facilitates the folding of the side portions 630 relative to the base portion 610 such that they can be easily erected when transforming the convertible container 600 between activity mat configuration and storage container configuration. Alternately, any combination of the base portion 610, side portions 630, and lid flap 620 may be formed as separate pieces of materials and then joined by stitching, gluing, or other techniques well known in the art for attaching pieces of materials together.
Referring to FIGS. 14-15, the zipper teeth 612 on the side portions 630 follow a generally curved path comprising a first positively oriented curved path portion 631 and a second negatively oriented curved path portion 632. The positively oriented curved path portion 631 is a counterclockwise direction and the negatively oriented curved path portion 632 is a clockwise direction. It is contemplated that in certain embodiments, the convertible container 600 can have one or more changes between the positively oriented curved oath portions 631 and the negatively curved path portions 632.
The convertible container 600 also includes two baffles 660, shown in FIGS. 14-16. The baffles 660 are configured to connect the base portion 610, the two side portions 630, and the lid flap portion 620. The two baffles 660 are biased inwardly toward the interior of the convertible container 600 to aid in transforming the convertible container 600 from the activity mat configuration to the storage configuration. The two baffles 660 can include a semi-rigid material that is scored or pre-folded to form an inward bias of the baffles 660. The baffles 660 also prevent abrupt notches in the activity mat that prevent the activity mat from lying flat and also present a contiguously shaped form to the activity mat. For example, without the baffles 660, an abrupt notch (see FIG. 16B), would be created and the activity mat would not lie flat in the notched area.
The convertible container 600 includes a closure flap portion 670. The closure flap portion 670 is similar to the overlapping described above in relation to the convertible container 100. The closure flap portion 670 is adapted to mate with an exterior portion of the base portion 610 to close the top of the convertible container 600 when in the storage container configuration. The closure flap portion 670 is helpful to prevent items stored within the container 600 from falling out during transport. It is contemplated that the closure flap portion 670 may be detachably sealed by a hook and loop fasteners 639, as shown in FIGS. 14-15 (e.g. Velcro) or by a zippered system shown in FIGS. 12-13.
The convertible container 600 can optionally include one or more shoulder straps 680. The straps 680 make it easier for a person to wear the convertible container in the storage container configuration as a back pack.
