Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging technology, and in particular to a tote bag. Background Technology
[0002] Tote bags are a common type of packaging container, typically featuring two handles connected to the bag body for easy carrying. The strength of the connection between the handles and the bag body directly determines the bag's load-bearing capacity. A strong connection ensures the tote bag is not easily broken or detached when loaded with heavy items, thus meeting the needs of various usage scenarios. Therefore, the strength of the connection between the tote bag's handles and the bag body directly affects the paper bag's performance, safety, and user experience.
[0003] In existing technology, tote bags are usually connected to the bag body by gluing or simple sewing. When carrying heavy objects, the tensile force at the connection is concentrated in a small area, making it easy to tear. Furthermore, when the bag body is carrying heavy objects, the direction of the tensile force acting on the handle is perpendicular to the contact surface between the handle and the bag body. This tangential force can easily tear the end of the handle from the bag body, and may even cause the end of the bag body and the handle to break off completely, resulting in the items carried in the bag (such as fragile ceramic or glass products) being accidentally spilled and damaged. Utility Model Content
[0004] The purpose of this invention is to solve the technical problem in the prior art that the connection strength between the handle and the bag body of a tote bag is weak, and the handle and the bag body are prone to break at the connection when carrying heavy objects.
[0005] To solve the above-mentioned technical problems, the present invention discloses a tote bag, which includes a bag body having a cavity and a handle provided at the opening of the bag body.
[0006] The handle fixing part is formed on the side wall of the bag near the opening, corresponding to the end of the handle, and the end of the handle is attached to and connected to the handle fixing part.
[0007] Furthermore, the tote bag also includes a lateral reinforcement provided in the handle fixing part, the side wall penetrating the bag body, and the end of the handle. The lateral reinforcement includes a first protrusion, a second protrusion, and a lateral force-bearing part located between the first protrusion and the second protrusion and extending in a direction perpendicular to the plane where the handle fixing part is located.
[0008] A passage is formed at the corresponding position of the handle fixing part and the end of the handle. A transverse force-bearing part is adapted to pass through the passage. The transverse force-bearing part is connected to a first protrusion and a second protrusion. The first protrusion protrudes from the handle fixing part on the side away from the end of the handle, and the second protrusion protrudes from the end of the handle on the side away from the handle fixing part.
[0009] The projected areas of both the first and second protrusions on the plane where the handle fixing part is located are larger than the cross-sectional area of the passage part.
[0010] This type of tote bag holds items through a cavity inside the bag, and the user can carry the bag by the handle at the opening. Because the handle is located at the opening, when the user carries the bag by the handle, the opening of the bag can be tightened, and the items are more securely loaded into the cavity. Even if the cavity is filled with a lot of items, they are not likely to spill out of the opening.
[0011] Specifically, when a tote bag without lateral reinforcement is lifted carrying a heavy load, the bag body experiences a downward pulling force from the load. The end of the handle, where the user directly applies force to the bag body, generates an upward pulling force. In other words, the pulling forces on the end of the handle and the handle fixing part are in opposite directions. This opposite pulling force creates shear stress at the contact surface between the end of the handle and the handle fixing part. This shear stress causes the material at the contact surface to gradually undergo plastic deformation. When the shear stress exceeds the tensile strength of the material, the material tears, leading to a break in the connection between the handle and the bag body. The present embodiment of the tote bag provides a transverse reinforcement member that penetrates the side wall of the bag body and the end of the handle at the handle fixing part. This reinforcement member directs the shear stress acting on the handle fixing part and the end of the handle through the transverse force-bearing part, dispersing the shear stress on the mating surface and improving the stress distribution on the mating surface. Furthermore, the transverse force-bearing part of the transverse reinforcement member has high shear strength in the axial direction, preventing easy deformation. The transverse force-bearing part also reacts to the handle fixing part and the end of the handle, limiting the deformation of the material under tensile force and reducing the likelihood of tearing. Therefore, this tote bag, by providing a transverse reinforcement member at the handle fixing part, improves the stress distribution between the handle fixing part and the end of the handle, reducing the risk of tearing between them.
[0012] Furthermore, the projected areas of the first and second protrusions of the lateral reinforcement on the plane where the handle fixing part is located are both larger than the cross-sectional area of the passage part, playing a dual role of preventing detachment and providing support. On the one hand, the protrusions can prevent the lateral reinforcement from detaching from the passage part, ensuring the stability of the lateral reinforcement. Even if the contact surface between the end of the handle and the handle fixing part fails, the lateral reinforcement can still temporarily maintain the connection between the handle and the bag body, avoiding sudden tearing. On the other hand, when the handle is subjected to tension, the protrusions can provide additional support force, further enhancing the strength of the connection between the handle and the bag body.
[0013] Therefore, the tote bag provided by this utility model, by setting a transverse reinforcement between the end of the handle and the handle fixing part, can effectively prevent the handle from breaking at the connection point when carrying heavy objects, ensuring the normal use of the tote bag and the safe loading of items. When using this tote bag, users do not have to worry about the problem of the handle breaking at the connection point with the bag body, and can load and carry items with more confidence. This safe and reliable feature increases users' trust in the tote bag.
[0014] In one embodiment, the first protrusion, the transverse force-bearing portion, and the second protrusion are formed as a single unit. There are no connection gaps or weak points between the first protrusion, the transverse force-bearing portion, and the second protrusion. When subjected to external forces such as tension and pressure, the force can be transmitted evenly and smoothly throughout the entire structure, avoiding the risk of breakage due to insufficient strength at the connection.
[0015] Furthermore, this integrally molded transverse reinforcement reduces stress concentration caused by repeated stress on the connection points, lowering the possibility of material fatigue damage. This means that during long-term use, the connection points of the tote bag are less prone to loosening, deformation, or breakage, thus extending the tote bag's service life.
[0016] In another embodiment, the lateral force-bearing part includes a first force-bearing part and a second force-bearing part arranged sequentially along a direction perpendicular to the plane where the handle fixing part is located. The first force-bearing part is close to and connected to the first protrusion, and the second force-bearing part is close to and connected to the second protrusion. The ends of the first force-bearing part and the second force-bearing part facing each other are detachably connected.
[0017] This modular design of the lateral reinforcement is easy to assemble and disassemble. Even if a part of the lateral load-bearing component (such as the first or second load-bearing component) is damaged, only the damaged part needs to be replaced, rather than the entire reinforcement component. This greatly reduces maintenance costs and improves the maintainability of the tote bag. Furthermore, users can choose to replace the load-bearing component with one of different specifications or materials according to their needs and usage. For example, if it is necessary to bear heavier items, a higher strength load-bearing component can be replaced to meet different usage requirements.
[0018] Furthermore, since the lateral load-bearing parts can be disassembled and replaced, manufacturers can provide a variety of lateral reinforcement parts in different specifications, colors and materials to users to choose from, according to the needs of different users. Users can customize personalized lateral reinforcement parts according to their own preferences and actual usage scenarios, which increases the fun and appeal of the product.
[0019] Furthermore, an embodiment of this utility model also provides a tote bag, wherein the transverse force-bearing part is configured as a cylindrical structure, the first protrusion is configured as a first pressure plate or a plurality of first pressure strips arranged circumferentially along the passage part, and the second protrusion is configured as a second pressure plate or a plurality of second pressure strips arranged circumferentially along the passage part.
[0020] In this implementation, the lateral force-bearing part is designed as a cylindrical structure with isotropic properties. When the bag is carrying heavy objects, the tensile force can be evenly distributed in the lateral force-bearing part. That is, regardless of the direction of the tensile force, the lateral force-bearing part can effectively transfer the force to the handle fixing part and the handle end, avoiding stress concentration and thus reducing the risk of breakage at the connection. For example, when the user lifts the bag at different angles, the cylindrical lateral force-bearing part can stably withstand the tensile force, ensuring the structural integrity of the bag.
[0021] Furthermore, the cylindrical structure exhibits good compressive strength in the direction perpendicular to its axis. When the handle is subjected to pressure or impact, the cylindrical lateral force-bearing part can withstand a certain amount of pressure without easily deforming, providing reliable support for the handle and the bag body. For example, during stacking or transportation, the tote bag may be squeezed by other items, and the cylindrical lateral force-bearing part can effectively protect the connection between the handle and the bag body from damage.
[0022] Cylindrical structures are relatively easy to manufacture and can be produced using common processing techniques such as injection molding and extrusion. This simple manufacturing process not only reduces production costs but also increases production efficiency, enabling the mass production of tote bags to meet market demand.
[0023] Furthermore, both the first and second protrusions can be configured as pressure plates or pressure strips. For example, a larger contact area of the pressure plate makes the connection between the first pressure plate and the handle fixing part more secure. It can provide greater friction and adhesion, preventing the lateral force-bearing part from loosening or falling off in the handle fixing part. For instance, during long-term use, the first pressure plate can always maintain a tight connection with the handle fixing part, ensuring the reliability of the bag; while multiple pressure strips arranged circumferentially along the passage can fix the lateral force-bearing part from multiple directions, increasing the stability of the connection. Even if one or more pressure strips are damaged, the other pressure strips can still maintain the connection, reducing the risk of connection failure.
[0024] Furthermore, in order to improve the connection strength between the handle and the bag body, the present invention also provides a tote bag, wherein an auxiliary end is provided on the side of the end of the handle, spaced apart from and connected to the main body of the handle.
[0025] The handle end and the auxiliary end are located on the same side of the handle fixing part, and two transverse reinforcement members are provided respectively. The transverse force-bearing part of one transverse reinforcement member passes through the through part formed at the corresponding position of the handle fixing part and the handle end, and the transverse force-bearing part of the other transverse reinforcement member passes through the auxiliary through part formed at the corresponding position of the handle fixing part and the auxiliary end.
[0026] Alternatively, the end of the handle and the auxiliary end are located at corresponding positions on both sides of the handle fixing part, and the transverse force-bearing part of the transverse reinforcement passes through the auxiliary end and the through part formed at the corresponding positions of the handle fixing part and the end of the handle in sequence.
[0027] Compared to existing technologies where ordinary handles rely on a single end connected to the handle body to bear tensile force, this connection is prone to damage due to stress concentration when carrying heavy items. The tote bag provided in this embodiment adds an auxiliary end to the side of the handle. The handle end and the auxiliary end share the tensile force, resulting in a more even distribution of stress. For example, when the tote bag is full of heavy items, the two ends can work together to reduce the tensile force borne by a single end, greatly improving the overall load-bearing capacity of the handle and reducing the risk of handle breakage.
[0028] Specifically, the two ends (the handle end and the auxiliary end) are connected side by side to the handle body, forming a stable triangular structure (the handle body and the two ends form a triangle). This structure has higher mechanical stability. Compared with a single end, it can better resist external forces, such as shaking and collisions during the lifting process, making the tote bag more stable during use. Attached Figure Description

[0046] As mentioned in the background section, tote bags, as containers that are easy to carry, typically have handles at the opening of the bag, which users hold to carry and transport the items inside. However, in the prior art, the ends of the handles are usually glued to the bag body or simply sewn together. This connection method cannot withstand large loads, and the joint is prone to tearing due to repeated pulling, especially when the bag is carrying heavy items.
[0047] To improve the durability of tote bags and meet the demands of heavy-duty applications, this invention provides a tote bag with a transverse reinforcement member extending through the side wall of the bag body and the end of the handle at the handle fixing part. The transverse reinforcement member includes a first protrusion, a second protrusion, and a transverse force-bearing part located between the first and second protrusions and extending in a direction perpendicular to the plane of the handle fixing part. A passage is formed at the corresponding position of the handle fixing part and the end of the handle. The transverse force-bearing part adapts to pass through the passage and connects to the first protrusion protruding from the handle fixing part on the side opposite to the end of the handle, and the second protrusion protruding from the end of the handle on the side opposite to the handle fixing part. This tote bag significantly improves the strength of the connection between the handle and the bag body by adding the transverse reinforcement member.
[0048] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0049] like Figure 1 As shown, an embodiment of the present invention provides a tote bag 10, which includes a bag body 100 having a cavity and a handle 200 disposed at the opening of the bag body 100.
[0050] In this case, a handle fixing part is formed on the side wall of the bag body 100 near the opening, corresponding to the end 210 of the handle 200, and the end 210 of the handle 200 is attached to and connected to the handle fixing part.
[0051] This tote bag 10 is loaded with items through the cavity inside the bag body 100. The user can lift the tote bag 10 through the handle 200 at the opening of the bag body 100. Since the handle 200 is located at the opening, when the user lifts the handle 200, the opening of the bag body 100 can be tightened, and the items can be loaded into the cavity more securely. Even if a lot of items are loaded into the cavity, they are not likely to spill out of the opening.
[0052] Furthermore, the tote bag 10 also includes a lateral reinforcement 300 disposed in the handle fixing part, the side wall penetrating the bag body 100 and the end 210 of the handle 200. The lateral reinforcement 300 includes a lateral force-bearing part 310 extending in a direction perpendicular to the plane where the handle fixing part is located, and a first protrusion 320 and a second protrusion 330 respectively located at both ends of the lateral force-bearing part 310.
[0053] A passage portion is formed at the position corresponding to the handle fixing part and the end 210 of the handle 200. A transverse force-bearing part 310 is adapted to pass through the passage portion. The transverse force-bearing part 310 is connected to the first protrusion 320 and the second protrusion 330. The first protrusion 320 protrudes from the handle fixing part on the side away from the end 210 of the handle 200, and the second protrusion 330 protrudes from the end 210 of the handle 200 on the side away from the handle fixing part.
[0054] The projected areas of the first protrusion 320 and the second protrusion 330 on the plane where the handle fixing part is located are both greater than the cross-sectional area of the passage part.
[0055] like Figure 2 As shown, when the tote bag 10 without the lateral reinforcement 300 is lifted while carrying a heavy object, the bag body 100 (taking the side 110 as an example) will be subjected to a downward pulling force F1 from the heavy object. The end 210 of the handle 200 is the position where the user directly applies force to the bag body 100 through the handle 200. In this state, the end 210 of the handle 200 generates an upward pulling force F2. That is to say, the pulling forces (F1 and F2) on the end 210 of the handle 200 and the handle fixing part are in opposite directions. This opposite pulling force causes shear stress to be formed at the contact surface between the end 210 of the handle 200 and the handle fixing part. The shear stress will cause the material of the contact surface to gradually undergo plastic deformation. When the shear stress exceeds the tensile strength of the material, the material will tear, causing the connection between the handle 200 and the bag body 100 to fail. The tote bag 10 provided in this embodiment, as shown in the figure, Figure 3 As shown, a transverse reinforcement 300 is provided on the handle fixing part of the bag body 100, penetrating the side wall of the bag body 100 and the end 210 of the handle 200. Shear stress acting on the handle fixing part and the end 210 of the handle 200 is distributed to the transverse force-bearing part 310 through the reinforcement, dispersing the shear stress on the mating surface and improving the stress distribution on the mating surface. The transverse force-bearing part 310 of the transverse reinforcement 300 has high shear strength in the axial direction and will not easily deform. Furthermore, the transverse force-bearing part 310 reacts to the handle fixing part and the end 210 of the handle 200, limiting the deformation of the material of the handle fixing part and the end 210 of the handle 200 under tensile force, reducing the possibility of tearing. Therefore, this tote bag 10, by providing a transverse reinforcement 300 at the handle fixing part, improves the stress distribution between the handle fixing part and the end 210 of the handle 200, reducing the risk of tearing between them.
[0056] It should be noted that the material causing plastic deformation of the bonding surface due to shear stress may be at least one of the end 210 of the handle 200 and the handle fixing part. Alternatively, if the end 210 of the handle 200 and the handle fixing part are connected by a bonding agent, the bonding agent may also be a material that undergoes plastic deformation under shear stress. Or, if the end 210 of the handle 200 and the handle fixing part are sealed with a suture, the suture may also be a material that undergoes plastic deformation under shear stress. Furthermore, the material causing plastic deformation of the bonding surface under shear stress may not be a single material; it may be multiple materials undergoing plastic deformation simultaneously. Any plastic deformation of the materials at the bonding surface may affect the connection strength between the handle 200 and the bag body 100.
[0057] Furthermore, the projected areas of the first protrusion 320 and the second protrusion 330 of the lateral reinforcement 300 on the plane where the handle fixing part is located are both larger than the cross-sectional area of the passage part, playing a dual role of preventing detachment and providing support. On the one hand, the protrusions can prevent the lateral reinforcement 300 from detaching from the passage part, ensuring the stability of the lateral reinforcement 300. Even if the connection surface between the end 210 of the handle 200 and the handle fixing part fails, the lateral reinforcement 300 can still temporarily maintain the connection between the handle 200 and the bag body 100, avoiding sudden tearing. On the other hand, when the handle 200 is subjected to tension, the protrusions can provide additional support force, further enhancing the strength of the connection between the handle 200 and the bag body 100.
[0058] Therefore, the tote bag 10 provided by this utility model, by providing a transverse reinforcing member 300 between the end 210 of the handle 200 and the handle fixing part, can effectively prevent the handle 200 from breaking at the connection point with the bag body 100 when carrying heavy objects, ensuring the normal use of the tote bag 10 and the safe loading of items. When using the tote bag 10, users do not need to worry about the problem of the handle 200 breaking at the connection point with the bag body 100, and can load and carry items with greater confidence. This safe and reliable feature increases the user's trust in the tote bag 10.
[0059] The following is a detailed description of the bag body 100 of the tote bag 10.
[0060] The bag body 100 of the tote bag 10 is mainly used to enclose a cavity for holding items. The volume of the cavity when the bag body 100 is in the unfolded state determines the size of the items that can be held. Specifically, the cavity of the bag body 100 (when the bag body 100 is in the unfolded state) can be a cuboid, cube, ellipse, or other irregular shape. Those skilled in the art can design it according to actual conditions and specific needs. This embodiment does not impose any specific limitations on this.
[0061] Optionally, in one embodiment, the receiving cavity enclosed by the bag body 100 is cuboid. The sheet of the bag body 100 can be divided into a pair of side surfaces 110 facing each other in the width direction, a pair of connecting surfaces 120 facing each other in the length direction, and a bottom surface (not shown in the figure) located at the bottom in the height direction, depending on the position of the sheet relative to the receiving cavity. The top side is not provided with sheet to form a bag opening, so as to facilitate the entry and exit of items into the receiving space of the bag body 100.
[0062] Furthermore, regarding the way the material of the bag body 100 is arranged to form the cavity, in one embodiment, the bottom surface is connected to a pair of side surfaces 110. Each pair of side surfaces 110 has a connecting surface 121 on both sides in the length direction. One of the two connecting surfaces 121 located on the same side in the length direction extends to the edge in the width direction to form a first bag body connecting portion 130. The first bag body connecting portion 130 is superimposed and connected to the other connecting surface 121 to form a connecting surface 120 on both sides of the side surface 110. The connecting surface 120 and the bottom surface are connected by a second bag body connecting portion 140.
[0063] It should be noted that the first bag body connecting portion 130 between the two sub-connecting surfaces 121 can be an extension on any of the sub-connecting surfaces 121; the second bag body connecting portion 140 between the connecting surface 120 and the bottom surface can be an extension on the connecting surface 120, with the connecting surface 120 connecting to the bottom surface through its extension; or it can be an extension on the bottom surface, with the bottom surface connecting to the connecting surface 120 through its extension; the second bag body connecting portion 140 can also be a separately provided connecting piece, which is disposed between the connecting surface 120 and the bottom surface, thereby serving to connect the bottom surface and the connecting surface 120. In summary, whether it is the first bag body connecting portion 130 or the second bag body connecting portion 140, as long as it can serve to connect the two surfaces, its specific structure and shape can be designed by those skilled in the art according to actual conditions and specific needs, and this embodiment does not specifically limit it in this regard.
[0064] Of course, the specific structure of the bag body 100 of the tote bag 10 is not limited to the structure in the above embodiment. For example, in another alternative embodiment, the cavity enclosed by the bag body 100 is also rectangular, but the connection method between the various surfaces is different. Specifically, the bottom of a pair of side surfaces 110 and a pair of connecting surfaces 120 are all extended, and the bottom surface is formed by bonding the extensions of the pair of side surfaces 110 and the pair of connecting surfaces 120. This bag body 100 achieves the connection between the various surfaces by bottom sealing (i.e., sealing from the bottom surface of the bag body 100). Therefore, those skilled in the art can design the specific structure of the bag body 100 according to the actual situation and specific needs, and this embodiment does not limit it to a single structure.
[0065] Furthermore, the handle fixing part refers to the location on the bag body 100 for connecting the handle 200. It is no different from other parts of the bag body 100 in terms of texture and shape (e.g., thickness). In this type of tote bag 10, the handle fixing part is provided on a pair of sides 110, located near the bag opening. Of course, those skilled in the art can also provide the handle fixing part on a pair of connecting surfaces 120 according to actual conditions and specific needs; this embodiment does not limit this to a single option.
[0066] The following is a detailed introduction to the materials and connection methods of the bag body 100.
[0067] In this embodiment, the sheet material of the bag body 100 can be non-woven fabric, paper, or other materials commonly used in packaging bags. For example, when the sheet material of the bag body 100 is non-woven fabric, the first bag body connecting part 130 and the other connecting surface 121, as well as the connecting surface 120 or the bottom surface and the second bag body connecting part 140, are all heat-sealed. When the handle 200 is also made of non-woven fabric, the handle fixing part and the end 210 of the handle 200 are also heat-sealed. When the handle 200 is made of paper or other materials that cannot be heat-sealed, the handle fixing part and the end 210 of the handle 200 should be glued together.
[0068] For example, when the sheet material of the bag body 100 is paper, the first bag body connecting part 130 and the other connecting surface 121, as well as the connecting surface 120 or the bottom surface and the second bag body connecting part 140 are all glued together. Regardless of whether the handle 200 is made of paper or non-woven fabric, the handle fixing part and the end 210 of the handle 200 are glued together.
[0069] Therefore, those skilled in the art can design the material and connection method of the bag body 100 according to the actual situation and specific needs, and this embodiment does not limit it in this way.
[0070] The following section provides a detailed description of the structure of the handle 200 of the tote bag 10 and its connection with the bag body 100.
[0071] Handles 200 are usually located at the opening of the bag body 100. They not only make it easy for users to carry, but also tighten the opening of the bag body 100 when the user carries the handle 200, so that the items can be loaded into the cavity more securely.
[0072] It should be noted that when the handle 200 is connected to the bag body 100, the end 210 of the handle 200 can be located on the side of the handle fixing part closer to the receiving cavity, thereby ensuring that the outer surface of the bag body 100 is relatively beautiful and flat. Of course, in another alternative embodiment, the end 210 of the handle 200 can also be located on the side of the handle fixing part away from the receiving cavity, so as to avoid items frequently entering and exiting the receiving cavity of the bag body 100 through the opening, thereby wearing out the end 210 of the handle 200.
[0073] In one embodiment, the end 210 of the handle 200 is located on the side of the handle fixing part near the receiving cavity, and a pair of handles 200 are provided on opposite sides of the bag body 100. Each handle 200 is U-shaped and its two ends 210 are respectively connected to the corresponding handle fixing part on the bag body 100. The ends 210 of the pair of handles 200 are arranged opposite to each other in a direction perpendicular to the plane where the handle fixing part is located.
[0074] In this embodiment, the U-shaped handle 200 allows the user's fingers to easily reach in and grip the handle 200. Furthermore, when the user lifts the bag body 100 using the pair of handles 200, the bag body 100 is evenly stressed on the pair of sides 110 because the ends 210 of the pair of handles 200 are positioned opposite each other in a direction perpendicular to the plane where the handle fixing part is located, and the bag body 100 can be lifted smoothly.
[0075] Furthermore, in one embodiment, the handle 200 is a flat rope with a rectangular cross-section, the end 210 of the handle 200 is attached to the handle fixing part in a face-to-face contact manner, and a through hole is provided at the position corresponding to the end 210 of the handle 200 and the handle fixing part to form a through part.
[0076] In another alternative embodiment, the handle 200 is configured as a circular rope with a circular cross-section, and the end 210 of the handle 200 forms an annular knot around the handle fixing part. The hole formed by the annular knot and the corresponding position of the handle fixing part and the hole are provided with a through hole constituting a passage part.
[0077] The following is a detailed description of the transverse reinforcement 300 provided between the bag body 100 and the handle 200 of the tote bag 10.
[0078] To strengthen the connection between the handle 200 and the bag body 100 and improve the force distribution when the end 210 of the handle 200 contacts the handle fixing part, a transverse reinforcement 300 is provided at the position of the handle fixing part for the side wall of the bag body 100 and the end 210 of the handle 200. The transverse reinforcement 300 includes a first protrusion 320, a transverse force-bearing part 310, and a second protrusion 330 arranged sequentially along its length. A passage is formed at the corresponding position of the handle fixing part and the end 210 of the handle 200. The transverse force-bearing part 310 is adapted to pass through the passage. The first protrusion 320 protrudes from the handle fixing part on the side away from the end 210 of the handle 200, and the second protrusion 330 protrudes from the end 210 of the handle 200 on the side away from the handle fixing part.
[0079] The projected areas of the first protrusion 320 and the second protrusion 330 on the plane where the handle fixing part is located are both larger than the cross-sectional area of the passage part, which can prevent the transverse reinforcement 300 from detaching from the passage part.
[0080] like Figure 3 As shown, in one embodiment, the first protrusion 320, the transverse force-bearing part 310, and the second protrusion 330 are formed as one piece. When assembling this transverse reinforcement 300, the first protrusion 320 on one side of the transverse force-bearing part 310 can be extruded and formed first. After the transverse force-bearing part 310 passes through the handle fixing part and the end 210 of the handle 200, the second protrusion 330 on the other side of the transverse force-bearing part 310 can be extruded and formed.
[0081] There are no gaps or weak points between the first protrusion 320, the transverse force-bearing part 310 and the second protrusion 330. When subjected to external forces such as tension and pressure, the force can be transmitted evenly and smoothly throughout the entire structure, avoiding the risk of breakage due to insufficient strength at the connection.
[0082] Furthermore, this integrally molded transverse reinforcement 300 reduces stress concentration caused by repeated stress on the connection points, lowering the possibility of material fatigue damage. This means that during long-term use, the connection points of the tote bag 10 are less prone to loosening, deformation, or breakage, thus extending the service life of the tote bag 10.
[0083] like Figure 4As shown, in another embodiment, the lateral force-bearing part 310 includes a first force-bearing part 311 and a second force-bearing part 312 arranged sequentially along a direction perpendicular to the plane of the handle fixing part. The first force-bearing part 311 is close to and connected to the first protrusion 320, and the second force-bearing part 312 is close to and connected to the second protrusion 330. The ends of the first force-bearing part 311 and the second force-bearing part 312 facing each other are detachably connected. When assembling this lateral reinforcement 300, the first force-bearing part 311 connected to the first protrusion 320 can be first passed through the passage from the handle fixing part side, and then the second force-bearing part 312 connected to the second protrusion 330 can be aligned with the first force-bearing part 311 and passed through the passage from the end 210 side of the handle 200. The first force-bearing part 311 and the second force-bearing part 312 are connected to each other to form the lateral force-bearing part 310.
[0084] This split-structure lateral reinforcement 300 is easy to disassemble and assemble. Even if a part of the lateral load-bearing component 310, such as the first load-bearing component 311 or the second load-bearing component 312, is damaged, only the damaged part needs to be replaced, without replacing the entire reinforcement component. This greatly reduces maintenance costs and improves the maintainability of the tote bag 10. Furthermore, users can choose to replace the load-bearing components with different specifications or materials according to their needs and usage. For example, if it is necessary to bear heavier items, a higher strength load-bearing component can be replaced to meet different usage requirements.
[0085] In addition, since the lateral force-bearing part 310 can be disassembled and replaced, the manufacturer can provide a variety of specifications, colors and materials of lateral reinforcement parts 300 for users to choose from according to different user needs. Users can customize personalized lateral reinforcement parts 300 according to their own preferences and actual use scenarios, which increases the fun and appeal of the product.
[0086] Furthermore, the specific structures of the transverse force-bearing part 310, the first protrusion 320, and the second protrusion 330 will be described.
[0087] The transverse force-bearing portion 310, as the main force-bearing part of the transverse reinforcement 300, needs to extend along a direction perpendicular to the plane of the handle fixing portion and pass through the passage portion. In one embodiment, the transverse force-bearing portion 310 is set as a cylindrical structure with isotropic characteristics. When the tote bag 10 carries a heavy object, the tensile force can be evenly distributed in the transverse force-bearing portion 310. That is, no matter which direction the tensile force acts from, the transverse force-bearing portion 310 can effectively transfer the force to the handle fixing portion and the end 210 of the handle 200, avoiding stress concentration and thus reducing the risk of breakage at the connection. For example, when the user lifts the tote bag 10 at different angles, the cylindrical transverse force-bearing portion 310 can stably withstand the tensile force, ensuring the structural integrity of the tote bag 10.
[0088] Furthermore, the cylindrical structure exhibits good compressive strength in the direction perpendicular to its axis. When the handle 200 is subjected to compression or impact, the cylindrical lateral force-bearing portion 310 can withstand a certain amount of pressure without easily deforming, providing reliable support for the handle 200 and the bag body 100. For example, during stacking or transportation, the tote bag 10 may be squeezed by other items, and the cylindrical lateral force-bearing portion 310 can effectively protect the connection between the handle 200 and the bag body 100 from damage.
[0089] Furthermore, the cylindrical structure is relatively easy to manufacture and can be produced using common processing techniques such as injection molding and extrusion. This simple manufacturing process not only reduces production costs but also improves production efficiency, enabling the tote bag 10 to be mass-produced to meet market demand.
[0090] Of course, the structure of the transverse force-bearing part 310 is not limited to the cylindrical structure in the above embodiment. It can also be a triangular prism, a quadrangular prism or other irregular columnar structure. Those skilled in the art can design it according to the actual situation and specific needs. This embodiment does not make specific limitations in this regard.
[0091] Regarding the structure of the first protrusion 320 and the second protrusion 330, taking the structure of the first protrusion 320 as an example, as follows: Figure 5 and Figure 6 As shown, the first protrusion 320 can be configured as a pressure plate 301 or a pressure strip 302, such as... Figure 5 As shown, the larger contact area of the pressure plate 301 makes the connection between the first protrusion 320 and the handle fixing part more secure. It provides greater friction and adhesion, preventing the lateral force-bearing part 310 from loosening or falling off in the handle fixing part. For example, during long-term use, the pressure plate 301 can always maintain a tight connection with the handle fixing part, ensuring the reliability of the tote bag 10; Figure 6 As shown, the multiple pressure strips 302 arranged circumferentially along the passage can fix the transverse force-bearing part 310 from multiple directions, increasing the stability of the connection. Even if one or more pressure strips 302 are damaged, the other pressure strips 302 can still maintain the connection, reducing the risk of connection failure.
[0092] The structure of the second protrusion 330 is similar to that of the first protrusion 320. For example, the first protrusion 320 can be configured as a pressure plate 301, and the second protrusion 330 can be configured as multiple pressure strips 302; or both the first protrusion 320 and the second protrusion 330 can be configured as pressure plates 301; or both the first protrusion 320 and the second protrusion 330 can be configured as multiple pressure strips 302; or the first protrusion 320 can be configured as multiple pressure strips 302, and the second protrusion 330 can be configured as a pressure plate 301. Those skilled in the art can design according to actual conditions and specific needs, and this embodiment does not make specific limitations in this regard.
[0093] Furthermore, in one embodiment, a male connector (not shown in the figure) is provided on the surface of the second protrusion 330 of the transverse reinforcement 300 on one side near the cavity, and a female connector (not shown in the figure) is provided on the surface of the second protrusion 330 of the corresponding transverse reinforcement 300 on the other side near the cavity. It should be noted that the male connector and the female connector can be a snap-fit structure commonly used in the art.
[0094] In this embodiment, the transverse reinforcement 300 on one side can be connected to the female connector of the corresponding transverse reinforcement 300 on the other side via a male connector. This connection method is equivalent to forming a stable connection system on both sides of the handle fixing part, which greatly enhances the connection strength between the handle 200 and the handle fixing part. For example, when the tote bag 10 carries heavy items, the transverse reinforcements 300 on both sides, after being connected to each other, can jointly resist the pulling force, effectively preventing the handle 200 from loosening or falling off from the handle fixing part, making the overall structure of the tote bag 10 more stable.
[0095] In other words, the two transverse reinforcement members 300, when connected, form a cohesive whole that shares the load. When the tote bag 10 is subjected to tension, the two transverse reinforcement members 300 can share the tension simultaneously, rather than being borne solely by one side. This cohesive load-bearing method fully utilizes the function of the two transverse reinforcement members 300, greatly improving the load-bearing capacity of the tote bag 10.
[0096] Furthermore, in order to improve the connection strength between the handle 200 and the bag body 100, such as Figure 7 and Figure 8 As shown, an embodiment of the present invention also provides a tote bag 10, wherein an auxiliary end 220 is provided on the side of the end 210 of the handle 200, spaced apart from and connected in parallel to the body of the handle 200.
[0097] Among them, such as Figure 7As shown, in one embodiment, the end 210 and the auxiliary end 220 of the handle 200 are located on the same side of the handle fixing part, and two transverse reinforcing members 300 are respectively provided. The transverse force-bearing part 310 of one transverse reinforcing member 300 passes through the through part formed at the position corresponding to the handle fixing part and the end 210 of the handle 200, and the transverse force-bearing part 310 of the other transverse reinforcing member 300 passes through the auxiliary through part formed at the position corresponding to the handle fixing part and the auxiliary end 220.
[0098] When the end 210 and auxiliary end 220 of the handle 200 are located on the same side of the handle fixing part, two transverse reinforcement members 300 are provided respectively, and the transverse force-bearing part 310 of the transverse reinforcement member 300 passes through the through part or auxiliary through part formed at the corresponding position of the handle fixing part and the corresponding end 210. This design is equivalent to doubly fixing the end 210 and auxiliary end 220 of the handle 200, increasing the connection strength between the handle 200 and the handle fixing part. Even if one of the transverse reinforcement members 300 becomes loose or damaged, the other transverse reinforcement member 300 can still play a fixing role, ensuring that the handle 200 is firmly connected to the handle fixing part.
[0099] like Figure 8 As shown, in another alternative embodiment, the end 210 of the handle 200 and the auxiliary end 220 are located at corresponding positions on both sides of the handle fixing part, and the transverse force-bearing part 310 of the transverse reinforcement 300 passes through the auxiliary end 220 and the through part formed at the corresponding positions of the handle fixing part and the end 210 of the handle 200.
[0100] When the handle end 210 and the auxiliary end 220 are located at corresponding positions on both sides of the handle fixing part, the transverse force-bearing part 310 of the transverse reinforcement 300 passes through the auxiliary end 220, the handle fixing part, and the through-parts formed at corresponding positions of the handle end 210. This arrangement allows the transverse reinforcement 300 to simultaneously apply tension to the handle end 210 and the auxiliary end 220, making them tightly fixed to the handle fixing part, maintaining a good fixing effect regardless of the direction of the tension applied to the handle 200.
[0101] Compared to existing technologies where a common handle 200 relies solely on a single end 210 connected to the main body to bear tensile force, this connection is prone to damage due to stress concentration when carrying heavy items. The tote bag 10 provided in this embodiment adds an auxiliary end 220 beside the end 210 of the handle 200. The end 210 and the auxiliary end 220 share the tensile force, resulting in a more even distribution of stress. For example, when the tote bag 10 is full of heavy items, the two ends 210 can work together to reduce the tensile force borne by a single end 210, greatly improving the overall load-bearing capacity of the handle 200 and reducing the risk of handle breakage.
[0102] Specifically, the two ends (end 210 of the handle 200 and auxiliary end 220) are connected side by side to the main body of the handle 200, forming a stable triangular structure (the main body of the handle 200 and the two ends form a triangle). This structure has higher mechanical stability. Compared with a single end 210, it can better resist external forces, such as shaking and collisions during the lifting process, making the tote bag 10 more stable during use.
[0103] Furthermore, the opening of the tote bag 10 is formed directly from the top of the side wall of the bag body 100. It is made of the same material as the side wall of the bag body 100 and opens outwards, resulting in low strength. Since items enter and exit through this opening, the opening of the tote bag 10 is a very vulnerable part. Therefore, if... Figure 9 As shown, in one embodiment, the periphery of the opening of the bag body 100 is formed with a folded edge 150 that folds toward the inside of the receiving cavity. The folded edge 150 continuously surrounds the opening of the bag body 100, thereby reinforcing the bag opening.
[0104] On the opposite sides of the opening of the bag body 100, on the folded edges 150, at positions corresponding to the ends 210 of the handles 200, slits 151 are formed respectively. The end 210 of each handle 200 extends from the inside of the opening of the bag body 100 into the corresponding slit 151, extending to the space between the folded edge 150 and the handle fixing part. It should be noted that the end 210 of the handle 200 is only connected to the handle fixing part, or it can be fixed to both the handle fixing part and the folded edge 150. This embodiment does not specifically limit this.
[0105] The following explains the position and connection relationship of the transverse reinforcement 300 and the folded edge 150 when the bag opening is folded at 150.
[0106] like Figure 10 As shown, in one embodiment, the lateral force-bearing portion 310 of the lateral reinforcement 300 of the end 210 of the handle 200 passes through the handle fixing portion, the end 210 of the handle 200 and the folded edge 150 in sequence, and the second protrusion 330 is located on the side of the folded edge 150 away from the end 210 of the handle 200. When producing this kind of tote bag 10, the folded edge 150 needs to be folded inward first, and then the lateral reinforcement 300 is assembled.
[0107] like Figure 11As shown, in another alternative embodiment, the lateral force-bearing portion 310 of the lateral reinforcement 300 of the end 210 of the handle 200 passes through the handle fixing portion and the end 210 of the handle 200 in sequence. The second protrusion 330 is located between the folded edge 150 and the end 210 of the handle 200. The folded edge 150 covers the outer surface of the second protrusion 330 on the side away from the end 210 of the handle 200. When producing this tote bag 10, the lateral reinforcement 300 needs to be assembled first, and then the folded edge 150 needs to be folded inward.
[0108] It should be noted that since the tote bag 10 includes a pair of handles 200, and each handle 200 has two ends 210, each end 210 can adopt any of the above-mentioned assembly methods, and this embodiment does not make specific limitations on this.
[0109] Of course, the method of reinforcing the bag opening is not limited to the folded edge 150 in the above embodiment. In one embodiment, a reinforcing patch (not shown in the figure) is provided on the side wall of the bag body 100 near the cavity and at a position corresponding to the handle fixing part. The reinforcing patch is attached to the inner surface of the side wall of the bag body 100, and the reinforcing patch is at least partially located between the handle fixing part and the end 210 of the handle 200.
[0110] In this embodiment, the lateral force-bearing portion 310 of the lateral reinforcement 300 passes through the handle fixing portion, the reinforcing patch, and the end portion 210 of the handle 200 in sequence.
