DETAILED DESCRIPTION

[0039] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0040] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, inside, outside, top, bottom...) are only used to explain the relative position relationship between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0041] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, the element may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0042] See also Figures 1 to 9 The utility model provides a storage bag 10 in one embodiment, comprising a plurality of interconnected bag bodies 12, each bag body 12 comprising a bag sheet 14 and a connector 16 disposed at the edge of the bag sheet 14, and the bag sheets 14 of adjacent bag bodies 12 together form a storage cavity 18 for storing vegetables, fruits, and condiments such as onions, ginger, and garlic. An opening 19 is formed between the connectors 16 on adjacent bag bodies 12, and the opening 19 is connected to the storage cavity 18, so that items can be placed into the storage cavity 18 through the opening 19.

[0043] The specific number of the bag bodies 12 is not limited. In the present embodiment, the number of the bag bodies 12 is two, and the storage cavity 18 is located between the two bag bodies 12 .

[0044] It can be understood that the bag sheet 14 and the connecting piece 16 can be integrally formed of the same material, or they can be molded separately and then fixedly connected by glue or the like, or after the connecting piece 16 is molded, the bag sheet 14 can be directly molded on the connecting piece 16 by injection molding and fixed thereto.

[0045] Each connector 16 is provided with a magnetic element 20. The opening 19 can be closed by the magnetic attraction between the magnetic elements 20 in adjacent connectors 16. The opening 19 can be opened by overcoming the magnetic attraction between the magnetic elements 20. When the opening 19 is closed under the action of the magnetic attraction, the two adjacent connectors 16 fit together. When the opening 19 is open, the user can put items into the storage cavity 18 or take items out of the storage cavity 18 through the opening 19, and then close the opening 19 and fit the adjacent connectors 16. The storage cavity 18 can be sealed, thereby preserving the items in the storage cavity 18 and preventing odor contamination. In addition, the magnetic attraction method makes the operation of opening or closing the opening 19 simple and convenient for users to use. At the same time, the opening 19 can be opened or closed repeatedly, so that the storage bag 10 can be reused.

[0046] It is understandable that when the opening 19 is closed, the two adjacent connectors 16 may be sealed together, or there may be a certain gap between the adjacent connectors 16 after being attached. In this embodiment, when the opening 19 is closed, the two adjacent connectors 16 are sealed together to enhance the effect of preventing odor contamination and the function of preserving freshness.

[0047] In one embodiment, each bag sheet 14 includes a body 22 and a flange 24 provided at the edge of the body 22, the storage cavity 18 is located between two adjacent bodies 22, and the connector 16 is fitted and fixed to the flange 24. Specifically, the flange 24 extends outward from the outer edge of the body 22 to form a widening effect (the width of the flange 24 is greater than the wall thickness of the body 22). By providing the flange 24 at the edge of the body 22, the contact area with the connector 16 can be increased, so that the connector 16 can be fitted and fixed on the bag body 12. Specifically, the distance H between the end of the flange 24 away from the body 22 and the storage cavity 18 is 13.8 mm.

[0048] In this embodiment, the number of the bag sheets 14 and the number of the connecting members 16 are both two, and the two connecting members 16 are respectively disposed on two sides of the two bag sheets 14 that are close to each other.

[0049] Specifically, the body 22 and the flange 24 are integrally formed of the same material to ensure the connection strength between the body 22 and the flange 24 , while also avoiding the presence of a gap between the body 22 and the flange 24 , thereby ensuring the sealing performance of the storage cavity 18 .

[0050] The flange 24 is annular and surrounds the outer periphery of the body 22, and the flange 24 extends outward from the edge of the body 22. The flange 24 includes a fixing portion 26 and a sealing portion 28 located on one side of the fixing portion 26. The fixing portions 26 of the flanges 24 of two adjacent bag sheets 14 are fitted and fixed, and the sealing portions 28 are respectively connected to the connector 16. The flange 24 surrounds the outer periphery of the body 22, that is, the outer periphery of the storage cavity 18, and the fixing portions 26 of the flange 24 are fitted and fixed together to form a sealing effect. The sealing portion 28 is connected to the connector 16, and the adjacent connectors 16 can be sealed and fitted through the magnetic attraction between the magnetic suction parts 20, so that the storage bag 10 can form a sealing effect on the outer periphery of the storage cavity 18 to prevent odor contamination and preserve freshness.

[0051] The relative size relationship between the fixing portion 26 and the sealing portion 28 is not limited, and the circumferential size of the fixing portion 26 is greater than, equal to, or less than the circumferential size of the sealing portion 28. In this embodiment, the circumferential size of the fixing portion 26 is substantially equal to the circumferential size of the sealing portion 28.

[0052] The side of the sealing portion 28 close to the connecting member 16 is concave relative to the fixing portion 26 to form a recess 30, and the connecting member 16 is received in the recess 30 to enhance the compactness of the overall structure and reduce the sense of abruptness. In this embodiment, the depth of the recess 30 is substantially the same as the thickness of the connecting member 16, so when the connecting member 16 is installed to the sealing portion 28, the surface of the connecting member 16 close to the opening 19 is flush with the corresponding surface of the fixing portion 26 of the flange 24.

[0053] The wall thickness of the body 22 may be 0.6-1.0 mm, the thickness of the flange 24 (the dimension of the vertical fitting surface) may be 3-5 mm, and the depth of the recess 30 and the thickness of the connector 16 may be 1-3 mm.

[0054] Specifically, in this embodiment, the wall thickness D1 of the body 22 is 0.8 mm, the thickness D2 of the flange 24 (the dimension perpendicular to the bonding surface) is 4 mm, and the depth of the recess 30 and the thickness D3 of the connector 16 are both 2.3 mm.

[0055] like Figure 5 and Figure 6As shown, in some embodiments, a glue groove 32 is provided on the fixing portion 26, and adhesive is provided in the glue groove 32, and the fixing portions 26 of two adjacent bag sheets 14 are fixed by adhesive bonding. By providing adhesive between the two fixing portions 26, the two fixing portions 26 are attached and fixed together by the adhesive, so that parts of the two bag sheets 14 are fixedly connected together, and a sealing effect can also be formed between the two fixing portions 26.

[0056] One of the two sides of the adjacent fixing parts 26 is provided with a positioning column 34, and the other correspondingly is provided with a positioning hole 36 for the positioning column 34 to be inserted. The cooperation between the positioning column 34 and the positioning hole 36 can form a positioning effect during the assembly process of the storage bag 10. Only by inserting the positioning column 34 into the positioning hole 36, the two adjacent bag bodies 12 can be aligned and placed in the corresponding installation position, thereby reducing the difficulty of assembly.

[0057] The specific number of the positioning posts 34 and the positioning holes 36 is not limited, and can be one or more. In this embodiment, the number of the positioning posts 34 and the positioning holes 36 is multiple and corresponds to each other, and each positioning post 34 is inserted into a corresponding positioning hole 36. In one embodiment, a mounting groove 38 is provided on one side of the connecting member 16 connected to the bag sheet 14 (see Figure 8 ), the magnetic attraction member 20 is a magnet installed in the installation groove 38. When two adjacent connecting members 16 are close to each other, the magnets on the two connecting members 16 will generate a magnetic attraction force, and the two connecting members 16 are tightly attached together under the action of the magnetic attraction force, thereby forming a sealing effect.

[0058] Specifically, the depth of the mounting groove 38 is less than the thickness of the connecting member 16, that is, the mounting groove 38 does not penetrate the connecting member 16, and the thickness of the magnet is the same as the thickness of the mounting groove 38. In this embodiment, the thickness D3 of the connecting member 16 is 2.3 mm, and the thickness of the magnet and the depth D4 of the mounting groove 38 are both 2 mm.

[0059] The specific shape of the magnet is not limited, for example, it can be block-shaped, strip-shaped, etc. In the embodiment, the magnet is a magnetic block.

[0060] In other embodiments, the magnetic attraction member 20 may also be magnetic powder located in the connector 16. For example, during the process of molding the connector 16, the magnetic powder may be added to the raw material of the connector 16 so that the magnetic powder and the connector 16 are integrally molded.

[0061] In this embodiment, a stopper 40 is provided on one side of the connecting member 16 close to the corresponding bag sheet 14, i.e., the bag sheet 14 connected thereto, and the stopper 40 at least covers a portion of the mounting groove 38, so that the magnet is located between the connecting member 16 and the stopper 40, thereby preventing the magnet from falling out of the mounting groove 38. Specifically, the length of the stopper 40 is less than the length of the mounting groove 38, and the stopper 40 only covers a portion of the mounting groove 38, i.e., a portion of the magnet, and the mounting groove 38 and both ends of the magnet are located outside the stopper 40.

[0062] The limiting member 40 protrudes from the surface of the connecting member 16 facing the bag sheet 14 . The bag sheet 14 is provided with an escape portion 42 corresponding to the limiting member 40 . The limiting member 40 is received in the escape portion 42 to improve the compactness of the overall structure so that the connecting member 16 and the bag sheet 14 can fit together.

[0063] A groove 44 is provided on one side of the connecting member 16 connected to the bag sheet 14. The groove 44 surrounds the outer periphery of the mounting groove 38 and is spaced apart from the mounting groove 38. Fig. 9 As shown, the stopper 40 is generally U-shaped, including two side portions 401 spaced apart from each other and a connecting portion 402 connected between the two side portions, the two side portions 401 are respectively located at opposite sides of the mounting groove 38 and located in the groove 44, and the connecting portion 401 is located outside the mounting groove 38 and spans from one side of the mounting groove 38 to the other side to prevent the magnet from falling out of the mounting groove 38. Specifically, the connecting member 16 and the stopper 40 are integrally formed to ensure the connection strength.

[0064] In one embodiment, a side of the connecting member 16 close to the receiving cavity 18 is provided with an obliquely extending extension portion 46, the extension portion 46 extends into the receiving cavity 18, and the extension portions 46 on two adjacent connecting members 16 extend towards each other in a direction away from the connecting member 16. Figure 3 As shown, in the natural state (i.e., the extension portion 46 is not deformed), the extension portion 46 extends inwardly relative to the connecting member 16. When two adjacent connecting members 16 are attached together under the action of the magnetic attraction member 20, as shown in FIG. Figure 4 As shown, the extensions 46 on the two connectors 16 are squeezed and deformed against each other and tightly pressed together, thereby forming a certain sealing effect on the opening 19 on the inner side of the bag body 12 to further enhance the sealing performance of the storage bag 10.

[0065] Specifically, the connecting member 16 and the extending portion 46 are both made of soft rubber, and the connecting member 16 and the extending portion 46 are integrally formed.

[0066] The connecting member 16 has a fixing surface 161 and a fitting surface 162 which are arranged opposite to each other. The fixing surface 161 is fitted and fixed with the flange 24, and the fitting surface 162 is fitted with the fitting surface 162 of another adjacent connecting member 16. The extension portion 46 is close to the fitting surface 162 and extends obliquely from the inner edge of the fitting surface 162 toward the center of the receiving cavity (that is, it has both a radially inward component and an axially outward component), so that when the two adjacent connecting members 16 are close to each other but not yet in close contact, the extension portion 46 of one connecting member 16 extends obliquely toward the extension portion 46 on the other adjacent connecting member 16 ( Figure 3 In the thickness direction of the connecting member 16, the extension portion 46 protrudes outside the fitting surface 162, so when the opening 19 is closed under the action of the magnetic attraction member 20, the two adjacent extension portions 46 first contact each other, and as the two adjacent connecting members 16 gradually approach each other, the two extension portions 46 squeeze each other and deform, so as to be tightly pressed together, until the fitting surfaces 162 of the two adjacent connecting members 16 fit together, and after overcoming the magnetic attraction force to open the opening 19, the two adjacent connecting members 16 separate, and the two extension portions 46 separate from each other and return to the initial state under the action of their own elastic force.

[0067] When the opening 19 is in an open state, the extension 46 is in an inclined state relative to the connecting member. When the opening 19 is closed, the extension 46 changes from an inclined state to a straight state, and the fitting surface 162 is flush with the corresponding surface of the extension 46, that is, the surface close to another adjacent extension 46, and finally the two adjacent connecting members 16 and the two adjacent extensions 46 are respectively fitted together, increasing the fitting area of ​​the storage bag 10 at the opening 19, thereby enhancing the sealing performance. Specifically, when the opening 19 is closed, the two extensions 46 are sealed and fitted.

[0068] When the opening 19 is opened, the angle α between the extension 46 and the corresponding fitting surface 162 is 130° to 150°. Within the range of 90° to 180°, the smaller the angle between the extension 46 and the connector 16, the greater the deformation of the extension 46, the greater the difficulty of deformation of the extension 46, and the greater the elastic force after deformation. Controlling the angle between the extension 46 and the connector 16 within the range of 130° to 150° can avoid the problem of too small angle causing too great difficulty in deformation of the extension 46, and the problem of too large angle causing too small elastic force after deformation of the two extensions 46, resulting in failure to seal and fit, thereby achieving the effect of taking into account both the difficulty of deformation and the elastic force. Specifically, the angle between the extension 46 and the fitting surface 162 is 142°.

[0069] In one embodiment, an operating portion 48 is provided on the connecting member 16, and the operating portion 48 protrudes from the outer side of the bag sheet 14, and two adjacent operating portions 48 are stacked. When the user needs to open the storage bag, the two operating portions 48 can be separated first, and then one operating portion 48 can be grasped with both hands, and force can be applied in opposite directions to overcome the magnetic attraction between the magnetic elements 20, so that the adjacent connecting members 16 are separated, thereby opening the opening 19.

[0070] Specifically, the operating portion 48 and the connecting member 16 are integrally formed to fix the operating portion 48 and the connecting member 16 together.

[0071] Preferably, two adjacent operating portions 48 at one end away from the bag sheet 14 are spaced apart from each other, so that a gap is formed between the two operating portions 48 , so that the user can separate the two operating portions 48 for easy grasping.

[0072] In one embodiment, a protrusion 50 is provided on the outer side of the connecting member 16, and the protrusion 50 is located on the outer side of the bag piece 14. The protrusion 50 is penetrated by a hanging hole 52, so that the storage bag 10 can be hung on a hook through the hanging hole 52, or hung around the user's neck, wrist or ankle by using a hanging rope and the hanging hole 52 to prevent loss.

[0073] Specifically, the protrusion 50 and the connecting member 16 are integrally formed to fix the protrusion 50 and the connecting member 16 together.

[0074] like Fig.10 and Fig.11 As shown, in another embodiment, the storage bag 10a further includes a rivet 54, the two ends of the rivet 54 are riveted and fixed to two adjacent fixing portions 26a respectively, and the rivet 54 is arranged close to the sealing portion 28a. The two adjacent fixing portions 26a are glued and fixed together. In the process of moving the two sealing portions 28a away from each other, the position of the fixing portion 26a close to the sealing portion 28a will be subjected to a tearing force. By arranging the rivet 54 at the position of the fixing portion 26a close to the sealing portion 28a, the positions of the two fixing portions 26a close to the sealing portion 28a can be prevented from being pulled apart.

[0075] Specifically, the two fixing portions 26 a are respectively provided with rivet holes 56 , and two ends of the rivet 54 are respectively inserted into the rivet holes 54 on the two adjacent fixing portions 26 a .

[0076] The specific number of the rivets 54 is not limited, and may be one or more. In this embodiment, rivets 54 are provided at both ends of the fixing portion 26a close to the sealing portion 28a.

[0077] One of the two adjacent fixing portions 26a is provided with a positioning protrusion 58, and the other correspondingly is provided with a positioning groove 60, and the positioning protrusion 58 is embedded in the positioning groove 60. The cooperation between the positioning protrusion 58 and the positioning groove 60 can achieve a positioning effect during the assembly process, facilitating the assembly of the product.

[0078] The positioning protrusion 58 and the positioning groove 60 extend along the contour trajectory of the fixing portion 26a, that is, the contour shape of the positioning protrusion 58 and the positioning groove 60 is substantially the same as the contour shape of the fixing portion 26a, so as to form a more accurate positioning effect during the assembly process. Specifically, the positioning protrusion 58 and the positioning groove 60 are generally U-shaped and extend from one end of the fixing portion 26a to the other end respectively.

[0079] In this embodiment, two adjacent fixing portions 26a are glued and fixed, and the positioning protrusion 58 and the positioning groove 60 are provided to increase the contact area of ​​the two adjacent fixing portions 26a, so that the two fixing portions 26a are more firmly bonded. The above-mentioned embodiments are only preferred embodiments of the utility model, and cannot be used to limit the scope of protection of the utility model. Any non-substantial changes and replacements made by technicians in this field on the basis of the utility model belong to the scope of protection required by the utility model.
