Technical Field

[0001] This disclosure relates to a storage device and in particular to a connectable and reusable bag.

Background

[0002] Existing shopping bags, produce bags and store check-out bags are mostly single-use disposable plastic bags, which cannot be reused, and discarded plastic shopping bags are likely to cause environmental pollution. [0003] In the related art there are reusable bags, but the reusable bags require additional packaging, which results in additional waste.

[0004] The problem to be solved is how to reduce the packaging waste of reusable shopping bags. Summary

[0005] The connectable reusable bag disclosed herein aims to solve one of the technical problems existing in the prior art or related technologies. To this end, the first aspect of the present disclosure proposes a connectable reusable bag comprising: at least one first connecting piece and at least one second connecting piece; wherein the at least one first connecting piece is detachably connectable with the at least one second connecting piece such that a plurality of bags may be interconnected to form an assembly of connectable and reusable bags.

[0006] After multiple bags are connected by the first connecting piece and the second connecting piece, the bags can be transported and sold in rolls or stacked without additional packaging, thereby reducing the production of packaging waste of the bags. Customers can choose any number of bags to purchase, which is different from the fixed number of packaging bags in the prior art, which improves the customer's selectivity in purchasing bags.

[0007] It is worth noting that the bag is a reusable bag, which can be specifically woven with mesh bags, woven bags, cloth bags, and other different materials. The connectable reusable bag of the present invention is intended to replace disposable plastic bags in related technologies to achieve the purpose of reducing plastic waste.

[0008] It is understandable that a first connecting piece on a first bag may be detachably connected to a second connecting piece of a second adjacent bag to detachably connect the two adjacent bags together. A second connecting piece on the first bag can then be detachably connected with a first connecting piece on a third bag adjacent the first bag, and a first connecting piece on the second bag can be detachably connected with a second connecting piece on a fourth bag adjacent the second bag, so as to realize the interconnection of the bags together one by one into an assembly of bags. [0009] The first connecting piece and/or the second connecting piece can selected to be a common connecting structure so that the bag may be detachably connected through the first connecting piece and/or the second connecting piece to a backpack, handbag, another bag or other clothing having the same common connecting structure attached thereto, which is convenient for the user in daily use and carrying of the bag.

[0010] In addition, the connectable reusable bag in the above technical solution provided by the present invention may also have the following additional technical features:

[0011] In a preferred embodiment, the number of first connecting pieces is at least two, and the number of second connecting pieces is the same as the number of first connecting pieces.

[0012] In this design, each bag is provided with at least two first connecting pieces, and correspondingly, at least two second connecting pieces are provided. The number of the first connecting pieces and the second connecting pieces are set equal, so that each first connecting piece can be connected with the corresponding second connecting piece during the process of connecting the bags.

[0013] In a possible design, the first connecting piece and the second connecting piece are spaced apart on the bag.

[0014] In this design, a gap is provided between the first connecting piece and the second connecting piece. When the bags are connected by the first connecting piece and the second connecting piece the bags can be connected in a staggered manner, thereby reducing the thickness of the bag assembly formed by the interconnection of the bags. [0015] In a possible design, the first connecting piece and the second connecting piece are snap buckles, and the first connecting piece and the second connecting piece can be snapped together. The first connecting piece is a female snap, and the second connecting piece is a male snap or vice versa. [0016] In this design, the first connecting piece and the second connecting piece are both snap buckle structures, and one of the first connecting piece and the second connecting piece is configured as a female snap buckle, and the other is configured as a male snap buckle. By arranging the first connecting piece and the second connecting piece as male and female snap buckles, respectively, the first connecting piece and the second connecting piece can be buckled together and separated from each other.

[0017] In a possible design, the first connecting piece is a first carabiner buckle, the second connecting piece is a loop or a second carabiner buckle, and the first carabiner buckle can be detachably connected to the loop or the second carabiner buckle. [0018] In this design, one of the first connecting piece and the second connecting piece is configured as a first carabiner buckle, and the other is configured as a second carabiner buckle or a loop, and the first carabiner buckle can be detachably connected to the second carabiner buckle or the loop. By arranging the first connecting piece and the second connecting piece in the form of a carabiner buckle or loop, the first connecting piece and the second connecting piece can be connected and separated from each other.

[0019] It is worth noting that the buckle is selected in the form of a carabiner, which has the advantage of a firm connection. The loop can be optionally a metal or plastic ring structure, and the size of the loop needs to be adapted to the buckle, so that the buckle can be stably connected to the loop. The loop may also be a rope loop structure sewn onto the bag.

[0020] In a possible design, the first connecting piece is a button, the second connecting piece is a loop or a buttonhole embedded in the bag, the button is detachably connectable with the loop or the buttonhole. [0021] In this design, one of the first connecting piece and the second connecting piece is set as a button, and the other is set as a loop, such as a rope loop. The size of the button is adapted to the size of the rope loop to ensure that the button can be detachably connected with the rope loop. By arranging the first connecting piece and the second connecting piece in the form of buttons and loops, the first connecting piece and the second connecting piece can be buckled together and separated from each other.

[0022] In this design, one of the first connecting piece and the second connecting piece is set as a button, and the other is set as a buttonhole embedded in the bag. The size of the button matches the size of the buttonhole to ensure that the button can be detachably connected with the buttonhole. By arranging the first connecting piece and the second connecting piece in the form of buttons and buttonholes, the first connecting piece and the second connecting piece can be buckled together and separated from each other.

[0023] In a possible design, the first connecting piece is a magnetic buckle, the second connecting piece is a steel pin buckle or a magnetic pin buckle, and the first connecting piece and the second connecting piece can be detachably connected to each other. [0024] In this design, one of the first connecting piece and the second connecting piece is set as a magnetic buckle, and the other is set as a steel pin buckle or a magnetic pin buckle. The magnetic buckle is matched with the steel pin buckle or the magnetic pin buckle to ensure that the steel pin of the steel pin buckle or the magnetic buckle can be inserted inside the magnetic buckle. By arranging the first connecting piece and the second connecting piece in the form of a magnetic buckle and a steel pin buckle or a magnetic pin buckle, the first connecting piece and the second connecting piece can be connected and separated from each other.

[0025] When the connectable and reusable bag of the present invention is sold in the supermarket, the customer can purchase the bag at the checkout counter. In the process of using the bag, the user can also securely connect the bag to a backpack, handbag, another bag or piece of clothing through a steel pin buckle and a magnetic buckle arrangement.

[0026] In a possible design, the first connecting piece and the second connecting piece are matching hook and loop or hook and pile fastening structures sometimes referred to by the trademark VELCRO™. The first connecting piece and the second connecting piece can be attached and detached from each other.

[0027] In this design, the first connecting piece and the second connecting piece are selected as a hook and loop structure, wherein one of the first connecting piece and the second connecting piece is a hook structure, and the other is a loop structure. The hook structure can hook the loop structure to realize the repeated attachment and separation of the first connecting piece and the second connecting piece.

[0028] It is worth noting that the hook and loop structures are made of washable materials.

[0029] Illustratively, the hook and loop structures are made of polyester.

[0030] In a possible design, both the first connecting piece and the second connecting piece are selected as connecting ropes, and the first connecting piece and the second connecting piece can be tied together. [0031] In this design, by selecting both the first connecting piece and the second connecting piece as connecting ropes, the two connecting ropes can be connected together by knotting so that the first connecting piece and the second connecting piece can be knotted repeatedly and untied to realize the connection and separation between the first connecting piece and the second connecting piece. [0032] It is understandable that if the first connecting piece and the second connecting piece are selected as connecting ropes, the user can conveniently bind the bag to a backpack, handbag, another bag or clothing through the connecting ropes, thereby improving the portability of the bag.

[0033] In a possible design, the first connecting piece is a buckle, the second connecting piece is a connecting strap or belt, and the first connecting piece and the second connecting piece are detachably connectable.

[0034] In this design, by selecting the first connecting piece and the second connecting piece as a buckle and a connecting strap or belt, one of the first connecting piece and the second connecting piece is a buckle, and the other is a connecting strap including. The buckle and the connecting belt or strap can be detachably connected together so as to realize the connection and separation between the first connecting piece and the second connecting piece.

[0035] Optionally, the buckle is a buckle that includes a prong, and the connecting belt or strap includes a plurality of through holes. The prong of the buckle can be inserted into any one of the plurality of through holes. By selecting the prong to insert into different through holes, the overall connection structure composed of the first connecting piece and the second connecting piece can be adjusted in size. [0036] In one possible design, the first connecting piece and the second connecting piece are sewn to the bag.

[0037] In this design, the first connecting piece and the second connecting piece are stitched on the bag, and the first connecting piece, the second connecting piece and the bag are set together in the form of stitching, which is convenient for the connection of the reusable bags.

[0038] In one possible design, the first connecting piece and the second connecting piece are bonded to the bag by an adhesive.

[0039] In a possible design, the first connecting piece is a first magnetic strip, and the second connecting piece is a second magnetic strip or a metal strip, and the first connecting piece and the second connecting piece can be detachably connectable.

[0040] In this design, the first connecting piece is configured as a magnetic strip structure, and the second connecting piece is also configured as a magnetic strip structure or a metal strip structure. The magnetic attraction between the two strips makes the first connecting piece and the second connecting piece detachably connectable. The length of the magnetic strip structure in the first connecting piece may be at least twice that of the magnetic strip structure or the metal strip structure on the second connecting piece, so that only one magnetic strip structure may be provided as the first connecting piece, and at least two magnetic strip structures or metal strip structures may be correspondingly disposed as the second connecting piece, so as to simplify the magnetic strip structure on the first connecting piece and vice versa.

[0041] In one possible design, a first interlayer or pouch is provided on the bag, and the first connecting piece and the second connecting piece are arranged in the first interlayer. [0042] In this design, since the first magnetic strip and the second magnetic strip or metal strip can be attracted to each other with other non-resistive magnetic materials between them, a first interlayer is provided on the side wall of the bag, and the first connecting piece and/or the second connecting piece are arranged in the first interlayer. By arranging the first connecting piece and the second connecting piece in the first interlayer the connecting structure between the bags will not be exposed, which improves the integrity and aesthetics of the bags.

[0043] In a possible design, the bag includes a bag body provided with an opening and a containing cavity, the opening communicates with the containing cavity, and the first connecting piece and the second connecting piece are provided on the bag body.

[0044] In this design, the bag includes a bag body provided with an opening and a containing cavity, and the opening and the containing cavity are in communication with each other, so that the items to be stored in the bag can be placed into the containing cavity through the opening. The first connecting piece and the second connecting piece are both arranged on the bag body, so that the bag body of the bag can be connected to other similar bag bodies through the first connecting piece and the second connecting piece.

[0045] In a possible design, the bag body includes: a first enclosing portion; and a second enclosing portion connected to the first enclosing portion, so that the containing cavity and the opening are formed between the first enclosing portion and the second enclosing portion.

[0046] In this design, the bag body includes a first enclosing portion and a second enclosing portion. The first enclosing portion and the second enclosing portion are connected to each other to form the receiving cavity and the opening. By connecting the two enclosing portions to obtain the bag body structure the manufacturing process can be simplified, thereby reducing the production cost of the connectable reusable bag.

[0047] Exemplarily, the first enclosing portion and the second enclosing portion are selected as two pieces of cloth with the same size and shape. After reserving the opening, the edges of the first enclosing portion and the second enclosing portion are stitched or glued together to complete the bag body.

[0048] In a possible design, the first connecting piece and the second connecting piece on each bag body are located on the first enclosing portion or the second enclosing portion.

[0049] In this design, the first connecting piece and the second connecting piece on the bag body are both arranged on the same enclosing portion. When making the bag, the first enclosing portion and the second enclosing portion of the same shape and size can be uniformly processed. To simplify the process, the first enclosing portion is further provided with both the first connecting piece and the second connecting piece. Arranging the first connecting piece and the second connecting piece on the same enclosing portion can facilitate customers to fold the bag through the first connecting piece and the second connecting piece so that the bag may be secured to itself for storage.

[0050] Exemplarily, both the first connecting piece and the second connecting piece are arranged on the second enclosing portion. In the process of bag production, the first and second enclosing portions of the bag body are cut to a uniform size. The first connecting piece and the second connecting piece are attached on the surface of the second enclosing portion. Then the first enclosing portion and the second enclosing portion are stitched and connected together, thereby completing the manufacture of the bag body.

[0051] In a preferred embodiment, the connectable reusable bag further includes at least one identification tag, which is arranged in or on the bag body. The identification tag may be an electronic identification tag such as a radio frequency identification tag (RFID) or a near field communication tag (NFC). Other similar technologies may also be used, such electronic article surveillance (EAS) or acoustic magnetic security systems, Bluetooth or WiFi enabled identification tags, and tags using Zigbee or Thread protocols or any other protocol that is intended for short range transmission of data. The identification tag may also be a barcode identification tag, which may be a linear barcode or a two-dimensional barcode.

[0052] Preferably, the identification tag can be a tag that can be washed with soap and water, realizing the effect that the bag can be reused. Preferably, if the identification tag is an electronic identification tag, the user can read and write data stored in the electronic identification tag.

[0053] In a preferred embodiment, if the identification tag is a barcode, the barcode is printed on the tag and the tag is attached to the bag body where it can be easily read. In other embodiments, the bag further includes a receiving portion, which is arranged in the bag body, and a second interlayer or pouch is arranged in the receiving portion, and the identification tag is located in the second interlayer. Preferably, the receiving portion may be configured as a company and washing instruction label, and the second interlayer is provided in the company and washing instruction label, and the identification tag is located in the second interlayer. [0054] In this embodiment, the company and washing indicator labels can be made of cloth and sewn to the bag for easy cleaning and low cost. Storing and accommodating the identification tag through a separate container (such as company and washing instruction tags) can facilitate users to quickly find the location of the identification tag, thereby facilitating access to identification tag. Preferably, if the identification tag is an electronic identification tag, information in the electronic identification tag may be read and written to facilitate the electronic interconnection of all things. [0055] In a possible design in a preferred embodiment, the bag includes a fastener disposed in the opening, and the fastener is used to close the opening.

[0056] In this design, the bag also includes fasteners arranged at the opening position. The fasteners can close the opening and prevent the items in the bag from being lost from the opening. [0057] In a possible design, the bag further includes: a folded edge, which is arranged at an end of the bag body close to the opening, the folded edge and the bag body are arranged to form a third interlayer or pouch, and at least part of the fasteners are located in the third interlayer.

[0058] In a possible design, the bag further includes a folded edge, and the folded edge is sewn together with the bag body of the bag to form a third interlayer, the third interlayer is provided with channels through which at least part of the fasteners penetrate into the third interlayer, and at least some of the fasteners are movable in the third interlayer. The third interlayer restrains at least some of the fasteners inside it, preventing the fasteners from falling out of the opening of the bag. [0059] In one possible design, the fastener is a rope or drawstring.

[0060] In one possible design, the bag is made of recyclable materials.

[0061] In this design, the bag material can be polyester, cotton, woven net or mesh, linen, and other different woven materials.

[0062] It is understandable that bags made of recyclable materials can be recycled. Compared with the existing disposable bags, they are not only more environmentally friendly, but also have higher durability.

Detailed Description

[0093] In order to be able to understand the above objectives, features and advantages of the present discloser more clearly, the connectable reusable bag will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict.

[0094] In the following description, many specific details are explained in order to fully understand the connectable reusable bag. However, the connectable reusable bag can also be implemented in other ways different from those described here. Therefore, the scope of protection of the connectable reusable bag is not limited by the following descriptions of the specific embodiments and limitations disclosed.

[0095] Hereinafter, a connectable and reusable bag 110 according to some embodiments will be described with reference to Figures 1 to 26. [0096] As shown in Figures 1 to 6, a first embodiment provides the connectable and reusable bag 110, which includes: a bag body 113, at least one first connecting piece 111 and at least one second connecting piece 112. The first connecting piece 111 and the second connecting piece 112 on one bag 110 may be detachably connected with other adjacent bags 110 having the same connecting pieces 111 , 112. The first connecting piece 111 on one adjacent bag 110 being detachably connectable with the second connecting piece 112 on the adjacent bag 110.

[0097] In one embodiment, a plurality of the bags 110 are connected together by the first connecting pieces 111 connected to the second connecting pieces 112 to form a bag assembly 100, which can be in the form of a roll or a stack for transportation, sales and distribution, thereby reducing the generation of packaging waste of the bags 110. The customer can choose any number of bags 110 to purchase from the bag assembly 100, which is different than having to purchase a fixed number of pre-packaged bags in the prior art. This improves the customer's selectivity in purchasing bags 110.

[0098] It is worth noting that the connectable and reusable bag 110 as disclosed herein can be specifically selected as a mesh bag, a woven bag or a cloth bag, etc., which is used to replace the disposable plastic product bag in the related technology, so as to reduce plastic waste.

[0099] It is understandable that the first connecting piece 111 of a first one of two adjacent bags 110 is connected to the second connecting piece 112 on the other adjacent bag 110, so that the first connecting piece 111 and the second connecting piece 112 are connected. The bags 110 may be detachably connected together one by one in sequence.

[0100] In some embodiments, the bag 110 is connected by the first connecting piece 111 and the second connecting piece 112 to form the bag assembly 100, and the bag 100 assembly can be wound and stored on a roller structure (not shown in the figures). In the embodiment where the bag 110 is rectangular, two adjacent bags 110 may be connected by a long side or a short side, so as to adapt to the length of the roller structure.

[0101] The first connecting piece 111 and/or the second connecting piece 112 may be a common connecting structure such that the bag 110 may be removably connected to a backpack, handbag, another bag or other clothing through the first connecting piece 111 and/or the second connecting piece 112 and the common connecting structure located on the backpack, handbag, another bag or clothing. This makes it convenient for users to carry bags 110 during daily use.

[0102] In one embodiment, the number of first connecting pieces 111 on each bag 110 is at least two, and the number of second connecting pieces 112 on each bag

110 is the same as the number of first connecting pieces 111.

[0103] In this embodiment, each bag 110 in the bag assembly 100 is provided with at least two first connecting pieces 111 and correspondingly provided with at least two second connecting pieces 112. The number of first connecting pieces 111 and second connecting pieces 112 is set equal so that each first connecting piece 111 on bag 110 in the bag assembly 100 can be connected to each corresponding second connecting piece 112 during the interconnection process.

[0104] As shown in Figures 7, 8 and 9, in any of the above embodiments, the first connecting piece 111 and the second connecting piece 112 are spaced apart on the bag 110.

[0105] In this embodiment, a gap is provided between the first connecting piece

111 and the second connecting piece 112, so that when the bags 110 are connected by the first connecting piece 111 and the second connecting piece 112, the bags 110 can be mutually connected in the longest direction. The bags 110 are connected in a staggered manner, thereby reducing the thickness of the bag assembly 100 formed by the interconnection of the bags 110.

[0106] In some embodiments, the first connecting piece 111 is provided at the open or top end of the bag 110, and the second connecting piece 112 is provided at the closed or bottom end of the bag 110 opposite the open end. When the bags 110 are connected by the first connecting piece 111 and the second connecting piece 112, the open end of one of the adjacent bags 110 and the closed bottom end of the other adjacent bag 110 are connected together. The bags 110 are connected end to end, which reduces the overlap size between two adjacent bags 110, thereby reducing the thickness of the connectable reusable bag assembly 100. [0107] It is understandable that a single bag 110 can be connected to itself through the first connecting piece 111 and the second connecting piece 112 provided on the bag 110 to realize the function of folding and securing the bag 110. Therefore, preferably, the first connecting piece 111 and the second connecting piece 112 may be arranged on the same side of the bag 110. [0108] In another embodiment, the first connecting piece 111 and the second connecting piece 112 may also be respectively arranged on opposite sides of the bag 110. In this case, the connecting pieces 111 are wrapped around the bag 110 to connect with the connecting pieces 112 to realize the folding and securing of the bag 110 to itself. [0109] As shown in Figures 7 and 8, for example, there are two first connecting pieces 111 and two second connecting pieces 112. The two first connecting pieces 111 are respectively arranged on the left and right sides of the open end of the bag 110, and the two second connecting pieces 112 are respectively arranged on the left and right sides of the bottom end of the bag 110 opposite to the open end. [0110] When it is necessary to connect at least two bags 110 together, the two first connecting pieces 111 on one bag 110 can be connected with the two second connecting pieces 112 on the other bag 110 to realize two bags 110 detachably connected together.

[0111] When a single bag 110 needs to be folded for storage, after the bag 110 is folded, the first connecting piece 111 at the open end of the bag 110 is connected to the second connecting piece 112 at the bottom closed end of the bag 110, so as to prevent the bag 110 from unfolding naturally. Thus, the folding and securing of the bag 110 is completed. [0112] As shown in Figures 7, 11 and 12, in any of the above embodiments, the first connecting piece 111 and the second connecting piece 112 are both snap buckles, and the first connecting piece 111 and the second connecting piece 112 can be snap locked together, wherein, the first connecting piece 111 is a male buckle 1112, and the second connecting piece 112 is a female buckle 1122, or vice versa.

[0113] In this embodiment, the first connecting piece 111 and the second connecting piece 112 are both snap buckle structures, and one of the first connecting piece 111 and the second connecting piece 112 is configured as a female buckle 1122, and the other is configured as a male buckle 1112. By arranging the first connecting piece 111 and the second connecting piece 112 as the male and female buckles 1112 and 1122, the first connecting piece 111 and the second connecting piece 112 can be buckled together and separated from each other.

[0114] As shown in Figures 13, 14, 15, 16, 17, 18, 19 and 20, in some embodiments, the first connecting piece 111 and the second connecting piece 112 can be selected as a two-piece buckle structure, that is, the female buckle 1122 and a surface buckle 1124 are connected to form the first connecting piece 111 (see Figures 17 to 20), and the male buckle 1112 and the surface buckle 1124 are connected to form the second connecting piece 112 (see Figures 13 to 16). The protruding part of the male buckle 1112 of the second connecting piece 112 can be matched with the recessed part of the female buckle 1122 of the first connecting piece 111 to realize the detachable connection of the first connecting piece 111 and the second connecting piece 112. The surface buckle 1124 can be used to facilitate the attachment of the female buckle 1122 and the male buckle 1112 to the bag 110, which is attained by inserting a portion of the bag body 113 between the surface buckle 1124 and the female buckle 1122 or the male buckle 1112 prior to connection of the surface buckle with the female buckle 1122 or the male buckle 1112.
