DETAILED DESCRIPTION

(6) The disclosed technology provides implementations and examples of a convertible bag. Some implementations of the disclosed technology suggest converting a bag between a folded state and an unfolded state. In the folded state, the bag has a relatively compact size as compared to the unfolded state and thus easier to carry. In the unfolded state, the bag has an opening area exposed to outside and having a size sufficient to allow a user to easily find an item in the bag.

(7) With conventional bags, there are some limitations to find a specific item since the conventional bags have an internal space reachable through a limited opening area of the bag. This inconvenience becomes more problem when the number of items carried in the bag increases. For example, there are various items carried in the bag, for example, makeup products, pens, pencils, toiletries, or even clothes, and people are often digging around to find the specific item they need. To address this inconvenience and provide an easier way to carry and find an item in a bag, the disclosed technology provides a bag convertible between a folded state and an unfolded state. This convertible bag can be converted into the unfolded state. The fully unfolded bag creates a tray-like structure with side structures to keep the contents contained. In the unfolded state, the bag has an opening exposed outside and reachable from many directions. This enables an easier access to the contents inside the bag and an ability to more quickly locate a desired item in the bag. The opening of the bag in the unfolded state has a greater size than that of the opening of the bag in the folded state. With this structure, the convertible bag allows to avoid wasting time in shuffling around in a bag or resorting to taking everything out from the bag. In some implementations, the bag has a side surface which is foldable to allow the bag to fold out flat. The bag conveniently folds back up with a quick magnetic closing mechanism to retake its original bag form.

(8) FIG. 1 shows a view showing an example of a convertible bag which is in a folded state based on some implementations of the disclosed technology. The bag in FIG. 1 is in the folded state. As shown in FIG. 1, the side surface of the bag includes the portions 15, 16, and 17 and the lid of the bag includes portions 8 and 9. In the folded state, the lid including the portions 8 and 9 is located over the side surface including the portions 15, 16, and 17 to close the bag. In the folded state, the portions 8 and 9 contact to each other around a middle of the upper part. When the bag is shut or closed, as depicted in FIG. 1, the bag is completely closed with the portions 8 and 9 which function as the lid to securely contain the contents. In some implementations, the portions 8 and 9 of the bag remain being held together by the side surface including magnets based on the magnetizations of the magnets. As will be further explained, the portions 15, 16, and 17 form the side surface and each of the portions 15 and 17 includes magnets 12, 13, and 14 at different positions of the side surface. The magnets are attracted to one another due to magnetizations of the magnets when the portions 8 and 9 are folded up, thereby facilitating maintaining the bag in the folded state. Although FIG. 1 shows one side surface including portions 15, 16, and 17, the bag has an opposite side surface including portions corresponding to the portions 15, 16, and 17.

(9) In FIG. 1, the dotted circle shows the three stacked magnets 12, 13, and 14 that are overlapping one another. In some implementations, the portions 15 and 17 include two layers of fabric and the magnets 12, 13, and 14 may be disposed between the two layers of fabrics and thus not visible. One of the magnets 13 is located on the portion 16 (see FIGS. 3 and 4) which is at the middle of the side surface including portions 15, 16, 17. Other two magnets 13 and 14 are located on portions 15 and 17 which lie on the portion to complete the folded state. Although it is explained that the side surface includes three magnets 12, 13, 14 disposed on portions 15, 16, 17, respectively, the number of magnets and the number of portions is not limited to three and other implementations are also possible. In some implementations, the bag may have two exterior handles 6 and 7 for an easy carrying of the bag. The user can open the bag by using the handles 6 and 7 and the two portions 8 and 9 can be separated as shown in FIG. 3 to convert the bag into the unfolded state.

(10) FIG. 2 shows a view showing another example of a convertible bag which is in a folded state based on some implementations of the disclosed technology. The bag in FIG. 2 further includes the metal strip 10 that is arranged along a middle line of the lid. In some implementations, the metal strip 10 can be replaced with small pieces of a metal or an additional magnet to adhere to the portions 8 and 9. In some implementations, if the lid includes material that is sufficiently sturdy to keep the portions 8 and 9 adhered together, the bag can omit any additional element around the middle line of the lid.

(11) FIG. 3 shows a view showing an example of a convertible bag which is in a middle of conversion based on some implementations of the disclosed technology. The conversion of the bag into the unfolded state is achieved by separating the portions 8 and 9 from each other. This separation can be done in multiple ways, for example, by applying a force to the bag. In some implementations, the force can be applied to the sides 20 and 21 or the force can be applied to the portions 8 and 9. Such force can have the sides 20 and 21 of the bag to be unhinged and pushed outward. In FIG. 3, when the portions 8 and 9 forming the lid are separated from each other, the bag is open and has an opening area exposed to outside. The opening area is surrounded by the portions 15, 16, 17, 20, 21 which from a sidewall of the bag, Some of the portions 15, 16, 17, 20, 21 which form the sidewall of the bag are still held together by the magnets 12, 13, 14. When the bag is converted into an unfolded state as discussed with regard to FIG. 4, the portions 15, 16, 17 will form a tray side structure and portions 20 and 21 will form a tray bottom surface. When the bag is converted into the unfolded state, the portion 16 becomes the center of the tray side wall and the portions 15 and 17 are located on opposite sides of the portion 16 to provide the tray side wall.

(12) FIG. 4 shows a perspective view showing an example of a convertible bag which is in an unfolded state based on some implementations of the disclosed technology. Referring to FIG. 4, the bag has a tray-like structure including a rectangular base and a tray side structure formed along the rectangular base. The side structure includes first to fourth side surfaces, the first side surface 42 including the portions 15, 16, 17, the second surface 44 opposite to the first side surface, the third side surface including the portion 8, and the fourth side surface including the portion 9. FIG. 4 shows that each of the portions 8 and 9 is extended to overlap with the edges of the first side surface 42 and the second side surface 44. In FIG. 4, it is shown that the edges 18 and 19 of the second side surfaces 44 tuck inside the portions 8 and 9. As already discussed with regard to FIG. 1, the portions 8 and 9 can function as the lid when the bag is in the folded state where the portions 8 and 9 are arranged to contact to each other. In FIG. 4, the portions 8 and 9 form a part of the tray side structure.

(13) In the unfolded state, the magnets are separated from one another and located at different positions. In FIG. 4, the first side surface 42 includes magnets 12, 13, 14 that are disposed at different portions of the first side surface 42. The second side surface 44 includes magnets (see the dotted circles) that are disposed at different portions of the second side surface 44. Although FIG. 4 shows that each of the first and second side surfaces includes three magnets, the number of magnets is not limited to three and other implementations are also possible. As discussed with reference to FIG. 1, the magnets on different portions of each of the first and second side surfaces are attracted to one another based on the magnetizations of the magnets to allow the bag to be maintained in the folded state. In FIG. 4, the magnets are separated from one another by applying an external force to convert the bag to the unfolded state.

(14) A shown in FIG. 4, the bag in the unfolded state has an opening exposed to outside. Such opening has a greater size than that of the opening when the bag is in the folded state (see FIG. 3). The opening is surrounded by the tray side structure along an outside edge of the bottom surface of the bag. The bottom surface and the tray side structure can form any angle with respect to each other depending on designs or needs as long as the items in the bag can be contained in the bag. In some implementations, the first side surface 42 including portions 15, 16, and 17 may include material between two layers of fabric to increase stability and provide structural integrity. For example, the material of the first side surface 42 has rigidity sufficient enough to keep the items contained inside the bag. Portions 22 and 23 include two layers of fabric, without additional structural material, allowing the bag to be folded along the dotted lines as illustrated in FIG. 4. Thus, in response to a force applied to the bag, the portions 15 and 17, which include the portions 22 and 23, respectively, can be folded to convert the bag into the folded state. The second side surface 44 also includes material between two layers of fabric. For example, the material of the second side surface 44 has rigidity sufficient enough to keep the items contained inside the bag. The second side surface has portions corresponding to portions 15, 17, 22, and 23 to allow the bag to be folded up.

(15) FIG. 5 shows a plan view of an example of a convertible bag which is in an unfolded state based on some implementations of the disclosed technology. The interior base 24 of the tray on FIG. 4 includes a center portion 25 and movable portions 20 and 21 arranged on opposite sides of the center portion 25. In the unfolded state, the movable portions 20 and 21 are in a same plane as the central portion 25. In the folded state, the movable portions 20 and 21 form the sidewall of the bag as discussed with reference to FIG. 3. Thus, in the folded state, the movable portions 20 and 21 are not in the same plane as the central portion 25.

(16) The bag may contain various organizational elements such as mesh pockets, elastic loops, or zipper pockets. To convert the bag into the bag shape from the tray shape, a force can be applied to the bag such that the movable portions 20 and 21 stand upright or inclined with respect to the central portion, thereby forming the sides of the bag. In addition, the force applied to the bag can allow the portions of the first and second side surfaces to be folded and stayed as folded based on the magnetizations of the magnets.

(17) The bag disclosed in this patent document can be converted between the bag shape and the tray shape with a simple structure. Thus, there is very little or no additional costs incurred to allow the conversion of the bag. The interior and/or exterior fabric of the bag can vary depending on the intended use of the bag. The durable bag can be provided for long term use. The bag also has a wide variety of uses. Although some implementations are discussed above, the shapes and sizes of the bag can be modified in various manners.

(18) It is intended that the specification, together with the drawings, be considered exemplary only, where exemplary means an example and, unless otherwise stated, does not imply an ideal or a preferred embodiment. As used herein, the use of or is intended to include and/or, unless the context clearly indicates otherwise.
