Description

Storage bag

[0001] The present application claims priority to the Chinese patent application No. CN202421538926.1, filed on July 01, 2024, and entitled "Storage bag", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of preservation technology, in particular to a storage bag. BACKGROUND

[0003] In daily life, people usually choose to put vegetables, fruits and the like in a refrigerator to reduce the risk of corruption. However, due to the different odors of various vegetables and fruits, especially the strong odor of flavorings such as ginger, garlic and onion, there is a risk of odor transfer between other vegetables or fruits.

[0004] At present, people usually choose to first pack fruits or vegetables separately in a preservation bag, and then put the preservation bag containing fruits or vegetables in a refrigerator. However, the bag opening of the existing preservation bag cannot be closed, and therefore the effect of preventing odor transfer is not very good. SUMMARY

[0005] Therefore, the present application provides a storage bag to solve the above problems.

[0006] The storage bag provided by the present application comprises a bag body provided with a storage cavity, wherein the bag body is made of a deformable sheet material, and comprises a closed end and an open end. The open end is provided with an opening communicating with the storage cavity. The bag body comprises a body, and the storage cavity is arranged in the body. Opposite sides of the open end are respectively provided with a mounting portion extending outward from an outer edge of the body and a connecting piece fixed to the mounting portion. Each connecting piece is provided with a magnetic attraction piece. The magnetic attraction force generated between the magnetic attraction pieces in the connecting pieces causes the connecting pieces to adhere to each other, thereby closing the opening. The opening can be opened by overcoming the magnetic attraction force.

[0007] The storage bag provided by the present application is provided with connecting pieces at the open end of the bag body, and the connecting pieces are provided with magnetic attraction pieces. The storage bag can cause the adjacent connecting pieces to adhere to each other by the magnetic attraction force between the adjacent magnetic attraction pieces, thereby closing the opening and forming a closed effect on the storage cavity, thereby reducing the risk of odor transfer. Moreover, the magnetic attraction mode makes the operation of closing or opening the opening simple and convenient for users to use. Meanwhile, the opening can be repeatedly opened or closed, so that the storage bag can be repeatedly used. BRIEF DESCRIPTION OF DRAWINGS

[0029] The application will be further described below in conjunction with the drawings and specific embodiments. It should be noted that the following described embodiments or technical features can be combined with each other in any manner without conflict to form new embodiments.

[0030] It should be noted that all directional indications, such as upper, lower, left, right, front, back, inner, outer, top, bottom, etc., are only used to explain the relative positional relationship between components in a certain posture (as shown in the drawings) and change accordingly when the certain posture changes.

[0031] It should also be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there can be a middle element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be a middle element.

[0032] Referring to FIGS. 1-9, a storage bag 10 according to an embodiment of the present application includes a bag body 12 having a storage cavity 18, which can be used to store vegetables, fruits, and condiments such as onions, ginger, and garlic. The bag body 12 is made of a deformable material such as soft rubber. The bag body 12 includes a closed end 121 and an open end 122. The open end 122 is provided with an opening 19, which is in communication with the storage cavity 18, for putting or taking out items into or from the storage cavity 18 through the opening 19.

[0033] The bag body 12 includes a body 22, and the storage cavity 18 is arranged in the body 22. The opposite sides of the open end 122 are respectively provided with a mounting portion and a connecting piece 16 fixed to the mounting portion. The mounting portion extends outward from the outer edge of the body 22 by a certain width, facilitating the mounting of the connecting piece 16 to the body 22.

[0034] In this embodiment, the bag body 12 includes two bag pieces 14, each of which includes a body portion 221 and a flange 24 arranged on the body portion 221. The flange 24 extends outward from the edge of the body portion 221. The inner surface of the body portion 221 is concave, and the body portions 221 of the two bag pieces 14 together form the body 22, and the storage cavity 18 is located between the two body portions 221. The flange 24 surrounds the outer periphery of the body portion 221, and the flange 24 includes a fixing portion 26 distributed along the circumferential direction C and a sealing portion 28. The fixing portions 26 of the two flanges are fixedly attached, and the sealing portion 28 is used for connecting the mounting portion and the connecting piece. Each connecting piece 16 is fixedly attached to the sealing portion 28 of the corresponding flange 24.

[0035] Specifically, the flange 24 extends outwardly from the outer edge of the body portion 221 to form a widened effect (the width of the flange 24 is greater than the wall thickness of the body portion 221), by providing the outwardly extending flange 24 at the edge of the body portion 221, the contact area with the connecting piece 16 can be increased so as to fit the connecting piece 16 to the bag piece 14. Preferably, the distance H between the sealing portion 28 (i.e. the mounting portion) of the flange 24 and the receiving cavity 18 away from one end of the body portion 221 is 10-15 mm, for example 10 mm, 11 mm, 12 mm, 13 mm, 13.8 mm, 14 mm, 15 mm, etc. The width of the sealing portion 28 of the flange 24 is substantially equal to the width of the connecting piece 16, where the width refers to the size in the width direction X perpendicular to the circumferential direction C of the bag body 12 and the thickness direction Y of the bag body 12.

[0036] It can be understood that the bag piece 14 and the connecting piece 16 can be integrally formed from the same material, or can be separately formed and then fixedly connected by glue or the like, or the connecting piece 16 is formed, and then the bag piece 14 is directly formed on the connecting piece 16 by injection molding and fixed thereto. Alternatively, the bag piece 14 and the connecting piece 16 are both made of silica gel.

[0037] Each connecting piece 16 is provided with a magnetic attraction piece 20, and the opening 19 can be closed by the magnetic attraction force between the magnetic attraction pieces 20 in the two connecting pieces 16, and the opening 19 can be opened by overcoming the magnetic attraction force between the magnetic attraction pieces 20. When the opening 19 is closed under the action of the magnetic attraction force, the two connecting pieces 16 are in close contact with each other. When the opening 19 is in an open state, the user can put or take out the articles in the receiving cavity 18 through the opening 19, and then close the opening 19. After the two connecting pieces 16 are in close contact, the receiving cavity 18 can be closed, thereby preserving the articles in the receiving cavity 18 and preventing odor mixing. The magnetic attraction mode makes the opening 19 easy to open or close, which is convenient for the user to use. Moreover, the opening 19 can be repeatedly opened or closed, so that the storage bag 10 can be repeatedly used.

[0038] It can be understood that when the opening 19 is closed, the two connecting pieces 16 can be in sealed contact, or there can be a certain gap between the two connecting pieces 16 after being in close contact. In the present embodiment, the two connecting pieces 16 are in sealed contact when the opening 19 is closed, so as to enhance the effect of preventing odor mixing and preserving freshness.

[0039] In the present embodiment, the number of bag pieces 14 and the number of connecting pieces 16 are both two, and the two connecting pieces 16 are respectively arranged on the two sides close to the two bag pieces 14.

[0040] Specifically, the body part 221 and the flange 24 are integrally formed by the same material to improve the connection strength between the body part 221 and the flange 24, and also to avoid the existence of gaps between the body part 221 and the flange 24, thereby ensuring the sealing effect of the receiving cavity 18.

[0041] The flange 24 is annular and surrounds the outer periphery of the body part 221, and the flange 24 extends outward from the edge of the body part 221. The flange 24 includes a fixed part 26 and a sealing part 28 located on one side of the fixed part 26, and the fixed part 26 and the sealing part 28 are distributed along the circumferential direction C of the body part 221. The fixed parts 26 of the flanges 24 of the two bag pieces 14 are fixedly attached, and the sealing parts 28 serve as mounting parts to be connected with the connecting pieces 16, that is, in the present embodiment, the sealing parts 28 are mounting parts provided at the open ends 122 for mounting the connecting pieces 16. The flange 24 surrounds the outer periphery of the body part 221, that is, the outer periphery of the receiving cavity 18, and the fixed parts 26 of the flange 24 are fixedly attached together to form a sealing effect. The sealing parts 28 are connected with the connecting pieces 16, and the two connecting pieces 16 are sealingly attached together by the magnetic attraction force between the magnetic attraction members 20. Finally, the receiving bag 10 can form a sealing effect on the outer periphery of the receiving cavity 18 to prevent odor mixing and preserve freshness.

[0042] The relative size relationship between the fixed part 26 and the sealing part 28 is not limited, and the circumferential dimension C of the fixed part 26 is greater than, equal to, or less than the circumferential dimension C of the sealing part 28. In the present embodiment, the circumferential dimension C of the fixed part 26 is substantially equal to the circumferential dimension C of the sealing part 28.

[0043] The side of the sealing part 28 close to the connecting piece 16 is concave relative to the fixed part 26 to form a recess 30, and the connecting piece 16 is received in the recess 30 to enhance the compactness of the overall structure and reduce the sense of strangeness. In the present embodiment, the depth of the recess 30 is substantially the same as the thickness of the connecting piece 16, and thus, when the connecting piece 16 is mounted to the sealing part 28, the surface of the connecting piece 16 close to the opening 19 is flush with the corresponding surface of the fixed part 26 of the flange 24.

[0044] The wall thickness of the body part 221 can be 0.6-1.0 mm, the thickness (dimension perpendicular to the attached surface) of the flange 24 can be 3-5 mm, and the depth of the recess 30 and the thickness of the connecting piece 16 can be 1-3 mm. Specifically, in the present embodiment, the wall thickness D1 of the body part 221 is 0.8 mm, the thickness D2 (dimension perpendicular to the attached surface) of the flange 24 is 4 mm, and the depth of the recess 30 and the thickness D3 of the connecting piece 16 are both 2.3 mm.

[0045] As shown in FIG. 5 and FIG. 6, in some embodiments, the fixing part 26 is provided with a glue groove 32, and the glue groove 32 is provided with glue. The fixing part 26 of the two bag pieces 14 is glued and fixed by the glue. By setting the glue between the two fixing parts 26, the two fixing parts 26 are fixed together by the glue, thereby fixing and connecting the two bag pieces 14 together, and also forming a sealing effect between the two fixing parts 26.

[0046] One of the two sides of the two fixing parts 26 close to each other is provided with a positioning column 34, and the other side is provided with a positioning hole 36 for inserting the positioning column 34. The cooperation of the positioning column 34 and the positioning hole 36 can form a positioning effect during the assembly of the storage bag 10. By inserting the positioning column 34 into the corresponding positioning hole 36, the two bag bodies 12 can be aligned and positioned, thereby reducing the assembly difficulty.

[0047] The specific number of the positioning column 34 and the positioning hole 36 is not limited, which can be one or multiple. In the embodiment, the number of the positioning column 34 and the positioning hole 36 is multiple and one-to-one corresponding, and each positioning column 34 is inserted into a corresponding positioning hole 36.

[0048] In an embodiment, the side of the connecting piece 16 connected with the bag piece 14 is provided with a mounting groove 38 (see FIG. 8), and the magnetic attraction piece 20 is a magnet installed in the mounting groove 38. When the two connecting pieces 16 are close to each other, the magnets on the two connecting pieces 16 will generate a magnetic attraction force, and the two connecting pieces 16 will be tightly attached together under the action of the magnetic attraction force, thereby forming a sealing effect.

[0049] Specifically, the depth of the mounting groove 38 is less than the thickness of the connecting piece 16, that is, the mounting groove 38 does not penetrate the connecting piece 16, and the thickness of the magnet is the same as the depth of the mounting groove 38. In the embodiment, the thickness D3 of the connecting piece 16 is 2.3 mm, and the thickness of the magnet and the depth D4 of the mounting groove 38 are both 2 mm.

[0050] The specific shape of the magnet is not limited, for example, it can be block-shaped or strip-shaped. In the embodiment, the magnet is a magnetic block.

[0051] In other embodiments, the magnetic attraction piece 20 can also be magnetic powder located in the connecting piece 16. For example, during the forming of the connecting piece 16, the magnetic powder can be added to the raw material of the connecting piece 16, so that the magnetic powder is integrally formed with the connecting piece 16.

[0052] In the present embodiment, the connecting piece 16 is provided with a limiting piece 40 on the side close to the corresponding bag piece 14, i.e. the side connected with the bag piece 14, the limiting piece 40 covers at least part of the mounting groove 38, so that the magnet is located between the connecting piece 16 and the limiting piece 40, thereby preventing the magnet from falling out of the mounting groove 38 during assembly. Specifically, the length of the limiting piece 40 is less than the length of the mounting groove 38, and the limiting piece 40 only covers part of the mounting groove 38, i.e. part of the magnet, and the two ends of the mounting groove 38 and the magnet are located outside the limiting piece 40.

[0053] The limiting piece 40 protrudes from the surface of the connecting piece 16 facing the bag piece 14, and the bag piece 14 is provided with a recess 42 corresponding to the limiting piece 40, the limiting piece 40 is received in the recess 42, thereby improving the compactness of the structure and making the connecting piece 16 and the bag piece 14 fit together.

[0054] The side of the connecting piece 16 connected with the bag piece 14 is provided with a groove 44 surrounding the outer periphery of the mounting groove 38 and spaced from the mounting groove 38. As shown in FIG. 9, the limiting piece 40 is generally U-shaped, including two mutually spaced side portions 401 and a connecting portion 402 connected between the two side portions 401, the two side portions 401 are respectively located on opposite sides of the mounting groove 38 and are located in the groove 44, and the connecting portion 402 is located outside the mounting groove 38 and spans from one side of the mounting groove 38 to the other side, thereby preventing the magnet from falling out of the mounting groove 38. Specifically, the connecting piece 16 and the limiting piece 40 are integrally formed to ensure the connection strength.

[0055] In an embodiment, the connecting piece 16 is provided with an inclined extension 46 on the side close to the receiving cavity 18, the extension 46 extends into the receiving cavity 18, and the extensions 46 on the two connecting pieces 16 extend towards each other in a direction away from the connecting piece 16. As shown in FIG. 3, in a natural state (i.e. the extension 46 is not deformed), the extension 46 extends inwardly relative to the connecting piece 16, when the two connecting pieces 16 are fit together under the action of the magnetic attraction piece 20, as shown in FIG. 4, the extensions 46 on the two connecting pieces 16 are pressed and deformed relative to each other, and tightly abut 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 receiving bag 10.

[0056] Specifically, the connecting piece 16 and the extension 46 are both made of soft rubber, and the connecting piece 16 and the extension 46 are integrally formed.

[0057] The connecting piece 16 has opposite fixed surface 161 and abutting surface 162, the fixed surface 161 is fixed with the flange 24, the abutting surface 162 is mutually abutted with the abutting surface 162 of another connecting piece 16, the extension 46 is close to the abutting surface 162 and is inclinedly extended from the inner edge of the abutting surface 162 to the center of the accommodating cavity (i.e. having both radial inward component and axial outward component), so that when the two connecting pieces 16 are close to each other but not yet tightly abutted, the extension 46 of one connecting piece 16 is inclinedly extended to the extension 46 on the other connecting piece 16 (shown in Fig. 3). In the thickness direction Y of the connecting piece 16, the extension 46 protrudes out of the abutting surface 162, so when the opening 19 is closed under the action of the magnetic attraction piece 20, the two extensions 46 first contact, and as the two connecting pieces 16 gradually approach, the two extensions 46 are pressed against each other and deformed, so as to tightly abut together, until the abutting surfaces 162 of the two connecting pieces 16 are abutted together, after overcoming the magnetic attraction force to open the opening 19, the two connecting pieces 16 are separated, and the two extensions 46 are separated from each other and restored to the initial state under the action of their own elastic force.

[0058] When the opening 19 is in the open state, the extension 46 is in an inclined state relative to the connecting piece 16, and when the opening 19 is closed, the extension 46 changes from the inclined state to a flat state relative to the connecting piece 16, the abutting surface 162 is flush with the corresponding surface of the extension 46, i.e. the surface close to the other extension 46, so as to finally abut the two connecting pieces 16 and the two extensions 46 together, thereby increasing the abutting area of the receiving 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 abutted.

[0059] When the opening 19 is opened, the angle α between the extension 46 and the corresponding abutting surface 162 is 130°-150°. Within the range of 90° to 180°, the smaller the angle between the extension 46 and the connecting piece 16, the greater the deformation amount 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 connecting piece 16 within the range of 130°-150° can avoid the problem of too small angle leading to too great difficulty of deformation of the extension 46, and also avoid the problem of too large angle leading to too small elastic force after deformation of the two extensions 46, so as to achieve the effect of considering the difficulty of deformation and the elastic force. Specifically, the angle between the extension 46 and the abutting surface 162 is 142°.

[0060] In an embodiment, the connecting piece 16 is provided with operation portions 48, the operation portions 48 protrude outside the bag piece 14, and the two operation portions 48 are arranged in a stacked manner. When the user needs to open the storage bag, the two operation portions 48 can be separated first, and then the user can hold one operation portion 48 with each hand and force them in opposite directions, so as to overcome the magnetic attraction between the magnetic attraction members 20, separate the connecting piece 16, and thus open the opening 19.

[0061] Specifically, the operation portions 48 are integrally formed with the connecting piece 16, so as to fix the operation portions 48 and the connecting piece 16 together.

[0062] Preferably, the two operation portions 48 are spaced apart from each other at the ends away from the bag piece 14, so as to form a gap between the two operation portions 48, so that the user can separate the two operation portions 48, and the user can be facilitated to hold.

[0063] In an embodiment, the connecting piece 16 is provided with a protruding portion 50, the protruding portion 50 is located outside the bag piece 14, and the protruding portion 50 is provided with a hanging hole 52, so that the storage bag 10 can be hung on a hook through the hanging hole 52, or hung on the user's neck, wrist, ankle or other parts by cooperating with a hanging rope, so as to prevent loss.

[0064] Specifically, the protruding portion 50 is integrally formed with the connecting piece 16, so as to fix the protruding portion 50 and the connecting piece 16 together.

[0065] The connecting piece 16 can be fixedly connected with the magnetic attraction member 20 by an integral molding manner, and then fixedly connected with the bag body flange by a hot pressing or injection molding manner.

[0066] As shown in FIGS. 10 and 11, the storage bag 10a provided by the second embodiment of the present application is mainly different from the storage bag in the first embodiment in that the storage bag 10a further comprises a rivet 54, the two ends of the rivet 54 are riveted with two fixed portions 26a respectively, and the rivet 54 is arranged close to the sealing portion 28a. The two fixed portions 26a are glued together, and in the process of moving the two sealing portions 28a away from each other, the position of the fixed 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 fixed portion 26a close to the sealing portion 28a to fixedly connect the position of the fixed portion 26a close to the sealing portion 28a, the position of the fixed portion 26a close to the sealing portion 28a can be prevented from being pulled apart.

[0067] Specifically, the two fixed portions 26a are respectively provided with riveting holes 56, and the two ends of the rivet 54 are inserted into the riveting holes 56 of the two fixed portions 26a respectively.

[0068] The number of rivets 54 is not limited to one, but can be multiple. In this embodiment, the two fixed portions 26a are provided with rivets 54 near the two ends of the sealing portion 28a.

[0069] One of the two sides where the two fixed portions 26a are connected is provided with a positioning protrusion 58, and the other side is provided with a corresponding positioning slot 60, and the positioning protrusion 58 is embedded in the positioning slot 60. The cooperation between the positioning protrusion 58 and the positioning slot 60 can play a positioning effect during assembly, facilitating the assembly of the product. Specifically, the joint surface of the fixed portion 26a provided with the positioning slot 60 is provided with a pair of spaced protrusions, and the positioning slot 60 is formed between the spaced protrusions; the positioning protrusion 58 protrudes from the joint surface of the other fixed portion 26a towards the joint surface of the fixed portion 26a provided with the positioning slot 60. The positioning protrusion 58 and the positioning slot 60 can be in interference fit, clearance fit or loose fit.

[0070] The positioning protrusion 58 and the positioning slot 60 extend along the contour trajectory of the fixed portion 26a, that is, the contour shape of the positioning protrusion 58 and the positioning slot 60 is basically the same as the contour shape of the fixed portion 26a, so as to form a more accurate positioning effect during assembly. Specifically, the positioning protrusion 58 and the positioning slot 60 are substantially U-shaped and extend from one end of the fixed portion 26a to the other end, respectively. Of course, the positioning protrusion 58 can also be divided into multiple discrete segments, and the shape of the positioning slot 60 matches the shape of the positioning protrusion 58.

[0071] In this embodiment, the two fixed portions 26a are fixed by adhesive, and the positioning protrusion 58 and the positioning slot 60 can increase the contact area of the two fixed portions 26a, so as to make the two fixed portions 26a more firmly bonded.

[0072] The other structures of the storage bag 10a are basically the same as the corresponding structures of the storage bag 10 of Embodiment 1, and will not be described here.

[0073] Please refer to FIGS. 12 to 17, the main difference between the storage bag 10b provided in Embodiment 3 and the storage bag in Embodiment 1 is that:

[0074] In this embodiment, the storage bag 10b includes a bag body 12b provided with a storage cavity 18b inside, the bag body 12b is made of a deformable sheet material, for example, made of silica gel, the bag body 12b includes a closed end 121b and an open end 122b, the open end 122b is provided with an opening 19b communicating with the storage cavity 18b. The two sides of the open end 122b, i.e. the two sides near the opening 19b, are respectively provided with a connecting piece 16b, and each connecting piece 16b is respectively provided with a magnetic attraction piece 20b, and the connecting pieces 16b located on the opposite sides of the open end 122b can be adhered to each other through the magnetic attraction force between the magnetic attraction pieces 20b, so as to close the opening 19b, and the opening 19b can be opened by overcoming the magnetic attraction force between the magnetic attraction pieces 20b.

[0075] The structure of the magnetic attraction member 20b and the connecting member 16b in the embodiment is basically the same as that of the magnetic attraction member and the connecting member in the first embodiment. In the embodiment, each connecting member 16b is provided with a mounting groove 38b on the side connected with the opening end 122b, and the magnetic attraction member 20b is a magnet installed in the mounting groove 38b. When the two connecting members 16b are close to each other, the magnets in the two connecting members 16b will attract each other, so that the two connecting members 16b are tightly attached together under the magnetic attraction of the magnets, forming a sealing effect.

[0076] The number of the magnetic attraction members 20b on each connecting member 16b is multiple and one-to-one correspondence, and the multiple magnetic attraction members 20b are arranged at intervals along the circumferential direction C of the storage bag 10b.

[0077] The depth of the mounting groove 38b is less than the thickness of the connecting member 16b, that is, the mounting groove 38b does not penetrate the connecting member 16b. The mounting groove 38b extends from the side of the connecting member 16b connected with the opening end 122b to the other opposite side and is spaced a certain distance from the surface of the other opposite side, so that the connecting member 16b forms a support part for supporting the magnetic attraction member 20b on the side away from the opening end 122b, preventing the magnetic attraction member 20b from falling off from that side.

[0078] The end of the connecting member 16b connected with the opening end 122b is provided with a limiting member 40b, and the limiting member 40b covers part of the mounting groove 38b, so that the magnetic attraction member 20b is located between the connecting member 16b and the limiting member 40b. The limiting member 40b can limit the magnetic attraction member 20b, preventing the magnetic attraction member 20b from falling out of the mounting groove 38b.

[0079] The limiting member 40b protrudes from the surface of the connecting member 16b, and the opening end 122b is correspondingly provided with a avoiding part 42. The part of the limiting member 40b protruding from the connecting member 16b is located in the avoiding part 42, increasing the contact area of the connecting member 16b and the opening end 122b.

[0080] The bag body 12b includes a body 22b and two first flanges 62 and two second flanges 64 extending outward from the periphery of the body 22b. The storage cavity 18b is located inside the body 22b, and the first flange 62 and the second flange 64 extend outward from the body 22b. The two first flanges 62 are used as mounting parts and are respectively arranged on the opposite sides of the opening end 122b. Each first flange 62 is respectively provided with a connecting member 16b. The first flange 62 extends outward to have a widening effect, which can increase the contact area with the connecting member 16b, thereby facilitating the fixed connection of the connecting member 16b and the first flange 62.

[0081] The two second flanges 64 are respectively located at two ends of the first flange 62 along the receiving bag 10b, and are respectively fixed to opposite sides of the closed end 121b. Each second flange 64 is connected with the two first flanges 62. The second flange 64 extends from one end of the first flange 62 in a direction away from the opening 19b. The connection between the second flange 64 and the first flange 62 corresponds to the connection between the closed end 121b and the opening end 122b, that is, the end of the opening 19b close to the closed end 121b is located at the connection between the second flange 64 and the first flange 62. During the process of moving away from each other under the action of external force to open the opening 19b, the opposite sides of the opening end 122b will form a tearing force on the position of the closed end 121b close to the opening 19b. The connection of the second flange 64 with the position of the closed end 121b close to the opening 19b can enhance the overall strength of the position of the closed end 121b close to the opening 19b, thereby reducing the risk of tearing of the closed end 121b during the opening of the opening 19b.

[0082] The number of second flanges 64 is two, and each second flange 64 is fixedly connected with one end of the two first flanges 62. In the open state of the opening 19b, each second flange 64 forms a Y-shaped structure with the two first flanges 62 from the side. In this way, both of the two second flanges 64 can reduce the risk of tearing of the receiving bag 10b.

[0083] Optionally, the first flange 62 and the second flange 64 are integrally formed to enhance the connection strength between the first flange 62 and the second flange 64. The length of the first flange 62 is greater than the length of the second flange 64. The main function of the second flange 64 is to enhance the overall strength of the position of the closed end 121b close to the opening 19b to reduce the risk of tearing of the receiving bag 10b when it is opened. The overall strength of the position of the closed end 121b close to the opening 19b is less affected by the length of the second flange 64. Therefore, the length of the second flange 64 is set to be smaller than that of the first flange 62, which can reduce the volume of the second flange 64 without affecting the anti-tearing effect of the second flange 64, thereby reducing the overall volume and weight of the receiving bag 10b.

[0084] The bottom of the receiving bag 10b away from the opening 19b is a plane, that is, the side of the closed end 121b away from the opening end 122b is a plane, so that the receiving bag 10b can be placed in a corresponding position with the side where the opening 19b is located upward, to prevent the articles in the receiving bag 10b from falling out of the opening 19b in the receiving state. In other embodiments, the bottom of the receiving bag 10b away from the opening 19b can also be in a non-planar form.

[0085] The first flange 62 is generally in a U shape, and the two second flanges 64 are respectively connected to the two ends of the U-shaped first flange 62.

[0086] The width of the connecting piece is 0.5-1.5 cm, the length of the connecting piece is 20-30 cm, and the volume of the receiving cavity is 1000-2000 cm 3 , and the length of the bottom of the receiving bag is less than the length of the top. The length of the magnetic member 20b is 1-1.5 cm, the width of the magnetic member 20b is 0.3-0.5 cm, and the length of the magnetic member 20b is substantially equal to the gap between adjacent magnetic members 20b. The ratio of the width of the magnetic member 20b to the width of the connecting piece 16b is 1:2-2:3.

[0087] The ratio of the circumferential dimension of the closed end 121b to the circumferential dimension of the open end 122b is 2:1-5:1 to prevent the circumferential dimension of the opening 19b from being too large to affect the storage of the article.

[0088] Optionally, the magnetic member 20b is a neodymium iron boron magnet, and dysprosium and holmium elements are added. Adding dysprosium and holmium elements to the magnet can improve the coercive force of the magnet, improve the temperature resistance and stability of the magnet, and prevent the magnetic force from decaying in a high-temperature environment. The maximum working temperature that the magnet can withstand can reach more than 100 degrees Celsius. For example, when a neodymium iron boron permanent magnet with a brand of N52H is used, the maximum working temperature can reach 120 degrees Celsius or even 150 degrees Celsius. The silicone used to make the bag body and the connecting piece can also withstand temperatures above 100 degrees Celsius, such as 120 degrees Celsius or 150 degrees Celsius. This allows the storage bag to be placed in a microwave oven to heat the contents, and it can also be steamed and sterilized.

[0089] In an optional example, the weight percentage of dysprosium in the magnetic member 20b is about 3%, the weight percentage of holmium is about 2%, and the magnetic member 20b also includes about 4% of the metal iron and about 87% of the metal praseodymium and rubidium, and other iron and copper about 4%.

[0090] The surface of the magnetic member 20b is plated with a protective layer, such as a zinc layer, to protect the magnetic member 20b and reduce the risk of oxidation of the magnetic member 20b.

[0091] In an embodiment, the second flange 64 includes a main section 66 and a connecting section 67 connected between the main section 66 and the first flange 62. The main section 66 extends from the connecting section 67 in a direction away from the opening 19b. The end of the opening 19b is located at the connection between the connecting section 67 and the first flange 62, i.e. the second flange 64 extends from the end of the opening 19b in a direction away from the opening 19b. Optionally, the first flange 62, the connecting section 67, and the main section 66 are integrally formed to increase the connection strength between the connecting section 67 and the first flange 62 and the main section 66.

[0092] The strength of the connecting section 67 is less than that of the main body section 66, and the greater the strength means the greater the difficulty of deformation. Therefore, the difficulty of deformation of the connecting section 67 is less than that of the main body section 66. Since the connecting section 67 is connected to the first flange 62 at a position corresponding to the connection between the closed end 121b and the open end 122b, the opposite sides of the end of the open end 122b close to the closed end 121b will move away from each other or move closer to each other during the opening and closing of the opening 19b of the storage bag 10b. Therefore, the connecting section 67 will deform at the position connected to the first flange 62. By setting the strength of the connecting section 67 to be less than that of the main body section 66, the difficulty of deformation of the connecting section 67 connected to the first flange 62 is reduced, thereby reducing the resistance encountered during the opening and closing of the opening 19b. This facilitates the opening of the opening 19b for loading or unloading items from the storage bag 10b or cleaning the inside of the storage bag 10b, and also facilitates the automatic closing of the opening 19b under the action of the magnetic attraction member 20b to form a better sealing effect. Ultimately, the effects of preventing the storage bag 10b from tearing and facilitating the opening and closing of the opening 19b are achieved.

[0093] It can be understood that the specific way of making the strength of the connecting section 67 less than that of the main body section 66 is not limited, for example, different materials can be used to make the connecting section 67 and the main body section 66, respectively, wherein the material used to make the connecting section 67 has a strength less than that of the material used to make the main body section 66, so that the strength of the connecting section 67 is less than that of the main body section 66. Alternatively, the same material can be used to make the connecting section 67 and the main body section 66, and the thickness of the connecting section 67 is less than that of the main body section 66, so that the strength of the connecting section 67 is less than that of the main body section 66.

[0094] In an embodiment, the outer surface of the connecting section 67 is inwardly recessed to form a recessed portion 68, so that the thickness of the connecting section 67 is less than that of the main body section 66, thereby making the strength of the connecting section 67 less than that of the main body section 66, to facilitate the opening and closing of the opening 19b. By reducing the thickness of the connecting section 67 to reduce the strength of the connecting section 67, the main body section 66 and the connecting section 67 can be integrally formed by injection molding or hot pressing using the same material, which is beneficial to reduce the production difficulty of the storage bag 10b.

[0095] Alternatively, the opposite sides of the connecting section 67 are inwardly recessed, respectively, so that recessed portions 68 are formed on the opposite sides of the connecting section 67, respectively, to further reduce the thickness of the connecting section 67. In an optional example, the number of the second flanges 64 is two, each of the second flanges 64 includes a connecting section 67 and a main body section 66, and the two connecting sections 67 are connected to the two ends of the first flange 62, respectively. Each of the connecting sections 67 is provided with a recessed portion 68 to reduce the thickness.

[0096] Preferably, the recessed portion 68 is arc-shaped, and each connecting segment 67 is smoothly connected with the first flange 62, and each connecting segment 67 is smoothly connected with the main body segment 66. The arc-shaped recessed portion 68 includes a valley and slopes extending from both sides of the valley to the connecting segment 67 and the main body segment 66 respectively. Preferably, the positions of the valleys of the arc-shaped recessed portion 68 on both sides of the connecting segment 67 correspond to each other, so that the thickness of the connecting segment 67 at the corresponding valleys is the smallest, and gradually increases in the direction close to the main body segment 66 and in the direction close to the first flange 62 respectively. In this way, the first flange 62 can be bent relative to the connecting segment 67 during the opening and closing of the opening 19b. Preferably, the minimum thickness of the connecting segment 67 is smaller than the sum of the thicknesses of the two connecting members 16b. Alternatively, the thickness of the main body segment 66 is substantially equal to the sum of the thicknesses of the two first flanges 62, and is smaller than the sum of the thicknesses of the two connecting members 16b.

[0097] In an embodiment, the receiving bag 10b further includes a sealing member 70, and the opening end 122b has a locked state and an unlocked state, and the sealing member 70 is configured to enable the opening end 122b to switch between the locked state and the unlocked state. In the locked state, the sealing member 70 acts on the opening end 122b to prevent the connecting members 16b from being separated, i.e., to prevent the opposite sides of the opening end 122b from moving away from each other, thereby preventing the opening 19b of the receiving bag 10b from being opened. In the unlocked state, the sealing member 70 releases the action on the opening end 122b, and the opening 19b is allowed to be opened. Therefore, when the receiving bag 10b contains articles, the opening end 122b can be in the locked state by the sealing member 70, so as to prevent the opening 19b from being opened and causing the articles inside the receiving bag 10b to fall out.

[0098] The specific type of the sealing member 70 is not limited, for example, it can be a buckle member which switches between forming a buckling effect and releasing the buckling effect to enable the opening end to switch between the locked state and the unlocked state, or it can also be a sealing clamp which switches between being connected with the bag body and being separated from the bag body to enable the opening end to switch between the locked state and the unlocked state.

[0099] In an embodiment, the sealing member 70 is detachably connected with the two first flanges 62. When the opening end 122b is in the locked state, the sealing member 70 is connected with the two first flanges 62 located on the opposite sides of the opening end 122b, and at this time, the sealing member 70 can prevent the two first flanges 62 located on the opposite sides of the opening end 122b from moving away from each other, thereby achieving the effect of preventing the opening 19b from being opened. When the opening end 122b is in the unlocked state, the sealing member 70 is disconnected with the two first flanges 62, and the two first flanges 62 located on the opposite sides of the opening end 122b can move away from each other to open the opening 19b.

[0100] Optionally, the sealing member 70 is connected or disconnected with the first flange 62 by sliding. The sealing member 70 is provided with a sliding groove 72 on one side for slidingly matching with the first flange 62, and in the locked state, the two first flanges 62 are slidably inserted into the sliding groove 72. The sliding groove 72 extends through the sealing member 70 along the length direction of the sealing member 70. The first flange 62 can be inserted into or withdrawn from the sliding groove 72 from one end of the length direction of the sealing member 70, so that the sealing member 70 can be slid along the length direction to be connected or disconnected with the first flange 62, so as to switch the opening end 122b between the locked state and the unlocked state.

[0101] The sealing member 70 is recessed on the inner wall of the sliding groove 72 to form a limiting groove 74, and the limiting groove 74 extends through the sealing member 70 along the length direction of the sealing member 70. The side of the first flange 62 away from the connecting member 16b is provided with a limiting protrusion 76 for slidingly matching with the limiting groove 74, and in the locked state, the limiting protrusion 76 is slidably inserted into the limiting groove 74. The limiting protrusion 76 can limit the sealing member 70 in a direction perpendicular to the length direction of the sealing member 70, so as to prevent the sealing member 70 from moving relative to the first flange 62 in the direction to cause the sealing member 70 to be separated from the first flange 62, thereby improving the locking effect of the sealing member 70.

[0102] Optionally, the sealing member 70 is provided with limiting grooves 74 on the opposite inner walls of the sliding groove 72, and the two first flanges 62 located on the opposite sides of the opening end 122b are respectively provided with limiting protrusions 76, and each limiting protrusion is inserted into a corresponding limiting groove 74, so as to further enhance the limiting effect of the sealing member 70.

[0103] Preferably, the limiting protrusion 76 extends obliquely from the side of the first flange 62 away from the connecting member 16b, and the limiting protrusions 76 on the two first flanges 62 jointly form a dovetail limiting structure, so as to prevent the sealing member 70 from being separated from the first flange 62 along the depth direction of the opening 19b.

[0104] Preferably, the storage bag 10b is substantially hexahedral, including a pair of opposite end faces and two pairs of opposite side faces, the opening 19b is arranged on one end face and one pair of side faces, and the other end face is a closed end, and the thickness of the closed end is greater than that of the opening end.

[0105] The storage bag provided in the fourth embodiment of the present application mainly differs from the storage bag in the third embodiment in that:

[0106] Referring to FIGS. 18-21, in the present embodiment, the outer edge of the connecting piece 16c is provided with a first positioning portion 80 protruding outward, which protrudes from the outer edge of the connecting piece 16c and serves to position the connecting piece 16c during production, thereby reducing the risk of affecting the processing quality due to the shaking of the connecting piece 16c during production.

[0107] In an optional example, the receiving bag 10c is formed by secondary injection molding. During production, the magnetic member 20c can be first placed in a primary molding mold, and then the connecting piece 16c is injection molded to assemble the connecting piece 16c and the magnetic member 20c together, with one side of the magnetic member 20c embedded in the mounting groove 38c of the connecting piece 16c. Then, the assembly of the connecting piece 16c and the magnetic member 20c is placed in a secondary molding mold, and the bag body 12c is formed by secondary injection molding to fixedly assemble the connecting piece 16c and the bag body 12c together, with the first flange 62c of the bag body 12c sealing the other side of the magnetic member 20c. During the process of placing the assembly of the connecting piece 16c and the magnetic member 20c in the secondary molding mold, the first positioning portion 80 on the connecting piece 16c can cooperate with the corresponding positioning structure (e.g., a positioning groove) in the secondary molding mold to position the connecting piece 16c, so as to quickly locate the mounting position of the connecting piece 16c, and also reduce the risk of affecting the processing quality due to the shaking of the connecting piece 16c during the formation of the bag body 12c.

[0108] Optionally, the first positioning portion 80 is integrally formed with the connecting piece 16c, i.e., the connecting piece 16c and the first positioning portion 80 are formed simultaneously in the primary molding mold.

[0109] Each connecting piece 16c is provided with a first positioning portion 80 at each end, and each first positioning portion 80 can cooperate with the corresponding positioning structure in the secondary molding mold to position the two ends of the connecting piece 16c respectively, thereby improving the positioning effect.

[0110] The first positioning portions 80 on the two connecting pieces 16c are arranged one by one, and when the opening 19c is closed, the corresponding first positioning portions 80 on the two connecting pieces 16c abut against each other. The two first positioning portions 80 abutting against each other are identical in shape and size, so that the outer circumferential surfaces of the two first positioning portions 80 are flush when the two first positioning portions 80 abut against each other. Optionally, the first positioning portion 80 extends along the width direction of the connecting piece 16c.

[0111] The first positioning portion 80 is arranged at one end of the connecting piece 16c close to the second flange 64c, so that the first positioning portion 80 is located at the end of the opening 19c, preventing affecting the taking and placing of the received articles, and also facilitating reducing the sense of strangeness.

[0112] The connecting piece 16c is provided with a mounting groove 38c near one end of the second flange 64c, the mounting groove 38c extends along the extension direction of the first positioning part 80 and is partially located on the first positioning part 80, that is, the mounting groove 38c is partially located on the connecting piece 16c and partially located on the first positioning part 80. The magnetic attraction piece 20c is arranged in the mounting groove 38c, and along the length direction of the magnetic attraction piece 20c, one part is located in the mounting groove 38c on the connecting piece 16c and the other part is located in the mounting groove 38c on the first positioning part 80. In this way, the length direction of the magnetic attraction piece 20c at both ends of the length direction of the connecting piece 16c is basically consistent with the width direction of the connecting piece 16c, and the length direction of the magnetic attraction piece 20c at the middle part of the length direction of the connecting piece 16c is basically consistent with the length direction of the connecting piece 16c. In this way, the first positioning part 80 can be used to arrange the magnetic attraction piece 20c, and the opposite first positioning parts 80 on the two connecting pieces 16c can also be tightly attached together under the action of the magnetic attraction piece 20c, thereby increasing the attachment area of the storage bag 10c at the end of the opening 19c and improving the sealing effect at the end of the opening 19c. At the same time, the magnetic attraction piece 20c has high strength, and the first positioning part 80 is made of soft glue and has low overall strength, so that the magnetic attraction piece 20c is partially located in the first positioning part 80, which can improve the overall strength of the first positioning part 80 and prevent the first positioning part 80 from being deformed during production and affecting the positioning effect.

[0113] The connecting piece 16c is provided with a limiting piece 40c at the mounting groove 38c, and the limiting piece 40c is located on the side of the connecting piece 16c close to the first flange 62c. The limiting piece 40c covers part of the mounting groove 38c, thereby covering the magnetic attraction piece 20c located in the mounting groove 38c, preventing the magnetic attraction piece 20c from falling out of the mounting groove 38c.

[0114] The connecting piece 16c is provided with a second positioning part 82 on the side close to the first flange 62c, the second positioning part 82 protrudes in the thickness direction of the connecting piece 16c, and the first flange 62c is formed with a avoiding hole 84 corresponding to the second positioning part 82, and the second positioning part 82 is located in the avoiding hole 84. During processing, the side of the second positioning part 82 away from the connecting piece 16c can abut with the processing equipment, thereby forming a positioning effect on the connecting piece 16c in the thickness direction of the connecting piece 16c, preventing the connecting piece 16c from swinging in this direction during processing and affecting the processing quality.

[0115] In the secondary injection molding of the bag body 12c, the second positioning part 82 is in abutment with the secondary molding mold away from one end of the connecting piece 16c, so as to position the connecting piece 16c, preventing the connecting piece 16c from swinging in the extension direction of the second positioning part 82 in the secondary molding mold. When the bag body 12c is molded, the avoiding hole 84 is automatically formed on the first flange 62c at the position corresponding to the second positioning part 82. The avoiding hole 84 can or can not penetrate the first flange 62c in the thickness direction of the first flange 62c.

[0116] The second positioning part 82 is arranged on the side of the limiting piece 40c away from the mounting groove 38c. Optionally, the connecting piece 16c, the first positioning part 80, the limiting piece 40c and the second positioning part 82 are integrally molded by injection molding or hot pressing. The protruding direction of the first positioning part 80 is perpendicular to the protruding direction of the second positioning part 82. Therefore, the first positioning part 80 and the second positioning part 82 can position the connecting piece 16c in different directions, further enhancing the stability of the connecting piece 16c in the secondary molding mold.

[0117] The first flange 62c is provided with an outwardly extending shielding part 86 at one end close to the second flange 64c. The shielding part 86 is fixedly attached to the first positioning part 80 and shields part of the magnetic attraction piece 20c located on the first positioning part 80, preventing the magnetic attraction piece 20c on the first positioning part 80 from being exposed.

[0118] The size and shape of the shielding part 86 are the same as those of the first positioning part 80, so that the outer circumferential surface of the shielding part 86 is flush with the outer circumferential surface of the first positioning part 80.

[0119] As shown in FIGS. 19 and 20, the bag body 12c includes a bottom wall 12c1, a pair of side walls 12c2 and a pair of end walls 12c3. The bottom wall 12c1 is rectangular, including a longitudinal edge extending in the length direction and a pair of transverse edges extending in the width direction. The side walls 12c2 extend upward from the longitudinal edges of the bottom wall 12c1, and the end walls 12c3 extend upward from the transverse edges of the bottom wall 12c1. The first flange 62c is located at the top end of the corresponding side wall 12c2 and the two end walls, and the second flange 64c is located at the end wall and connected with the first flange 62c.

[0120] Optionally, a plurality of transparent windows are arranged on each side wall 12c2, so that the user can observe the objects in the receiving cavity.

[0121] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and substitutions made by those skilled in the art based on the present application are within the scope of protection of the present application.
