Description

Technical Field

[0001] This disclosure relates to a lifting buckle and a container assembly. Background Technology

[0002] Currently, there are various types of handles used on plastic containers on the market, mainly applied to heavy containers, including single handles, double handles, triple handles, and multi-handle handles. Existing multi-handle handles are mainly divided into non-tearable and locking types. Non-tearable handles are difficult to remove and require scissors or other tools; locking handles can easily cause containers to fall off if the container is shaken while being carried.

[0003] Therefore, in order to meet the usage requirements, it is necessary to propose a lifting fastener that can reliably lock the container in place and can be easily removed during use. Utility Model Content

[0004] This disclosure provides a fastener and container assembly that can simultaneously achieve locking and easy removal.

[0005] The first aspect of this disclosure provides a fastener, comprising:

[0006] At least two collars, each collar including an annular body and a tearing part, the annular body having a strength-reducing part, the tearing part being connected to the outer side wall of the annular body, the tearing part being configured to break the strength-reducing part under the action of external force, so that the annular body breaks in the circumferential direction;

[0007] At least one connecting part, the two ends of which are respectively connected to two adjacent collars; and

[0008] The handle is connected to the connecting part.

[0009] In some embodiments, at least two collars are arranged side by side along a first direction, a handle is located on one side of the connecting portion along a second direction, and each tear-off portion is located on the side of the collar away from the handle along the second direction, the second direction being perpendicular to the first direction.

[0010] In some embodiments, the strength-reducing portion extends radially obliquely relative to the annular body, and the tearing portion is connected to the area of ​​the annular body where a sharp portion is formed on the side of the strength-reducing portion.

[0011] In some embodiments, the lifting buckle includes at least three loops spaced apart along a first direction, the two ends of the handle are connected to different connecting portions, and the number of loops located on the outside of the handle along the first direction is equal.

[0012] In some embodiments, at least two collars are arranged side by side along a first direction, and the connecting portion includes a main body segment and an offset segment connected to each other. The offset segment is offset relative to the main body segment along a second direction toward a side away from the handle, and the second direction is perpendicular to the first direction.

[0013] The end of the handle is connected to one side of the recessed offset section, and the connection position is close to the plane where the center line of at least two collars is located.

[0014] In some embodiments, the connecting portion includes two main body segments, and an offset segment is connected between the two main body segments.

[0015] In some embodiments, in the second direction, the width of the offset segment is the same as the width of the body segment.

[0016] In some embodiments, the handle extends obliquely to one side and includes a first segment and two second segments. The first end of each of the two second segments is connected to the connecting portion. The two ends of the first segment are respectively connected to the second ends of the two second segments. A plurality of recesses for finger gripping are arranged side by side on the inner sidewall of the first segment.

[0017] In some embodiments, in a third direction extending along the thickness of the annular body, the handle extends toward a first side of the annular body in the third direction. A plurality of first positioning protrusions are provided circumferentially at intervals on the surface of the annular body on the first side, and a plurality of second positioning protrusions are provided circumferentially at intervals on the surface of the annular body on the second side. The positions of the plurality of first positioning protrusions and the plurality of second positioning protrusions correspond one-to-one, and the height of the second positioning protrusion is greater than the height of the first positioning protrusion.

[0018] A second aspect of this disclosure provides a container component, including:

[0019] At least two containers, each container comprising a body and a lid, the lid being used to close the opening of the body; and

[0020] In the above embodiment, at least two collars are fitted onto at least two containers located below the lid.

[0021] The lifting buckle of this embodiment, when engaged with a container, forms a complete ring in the circumferential direction with the annular body, reliably securing the container and preventing it from detaching from the container even during hand-carrying. By providing a strength-reducing portion on the annular body and a tearing portion near the strength-reducing portion, the strength-reducing portion can be broken when an external force is applied, causing the annular body to break in the circumferential direction, thereby facilitating the removal of the ring from the container.

[0031] The embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of this disclosure by way of example, but should not be used to limit the scope of this disclosure, that is, this disclosure is not limited to the described embodiments.

[0032] In the description of embodiments of this disclosure, the term "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two).

[0033] This disclosure uses terms such as "upper," "lower," "top," "bottom," "front," "back," "inner," and "outer" to indicate orientation or positional relationships. This is only for the convenience of describing this disclosure and is not intended to indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the scope of protection of this disclosure.

[0034] Furthermore, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. "Vertical" does not mean strictly vertical, but rather within the permissible range of error. "Parallel" does not mean strictly parallel, but rather within the permissible range of error. The directional terms appearing in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this disclosure.

[0035] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure depending on the specific circumstances.

[0036] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least some of the embodiments disclosed herein. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0037] This disclosure provides a carrying clip for installation on the receiving portion of a container at an open position, below the lid. For example, the container may hold beverages or cooking oil, and can be a bottle, bucket, or similar structure. The carrying clip is used to connect at least two containers together to form a container assembly, facilitating sale or transport as a whole. After purchase, the consumer needs to remove the carrying clip from the container.

[0038] In some implementations, such as Figures 1 to 6 As shown, the lifting fastener includes:

[0039] At least two collars 1, each collar 1 including an annular body 11 and a tearing part 12, the annular body 11 is provided with a strength weakening part 13, the tearing part 12 is connected to the outer side wall of the annular body 11, and the tearing part 12 is configured to destroy the strength weakening part 13 under the action of external force, so that the annular body 11 breaks in the circumferential direction;

[0040] At least one connecting part 2, with its two ends respectively connected to two adjacent collars 1; and

[0041] Handle 3 is connected to connector 2.

[0042] The collar 1 can be provided in two, three or more quantities, and the annular body 11 can be circular or other shapes adapted to the opening area of ​​the container. The collar 1 may also include a locking part 16, which is connected to the upper part of the annular body 11. The cross-section of the locking part 16 gradually decreases from the root to the free end to form a frustum shape, and the locking part 16 is provided with multiple slots 17 at intervals along the circumference. This structure can not only adapt to the shape of the area below the opening of the container's receiving part, but also facilitate installation and reduce the requirements for the dimensional accuracy of the locking part 16.

[0043] The strength-reducing portion 13 is elongated and can be designed as a thickness-reduced portion, which penetrates the inner and outer walls of the annular body 11, or the thickness-reduced portion penetrates the outer wall of the annular body 11 but still has a predetermined distance from the inner wall. Optionally, the strength-reducing portion 13 uses a strength-reducing material in this area.

[0044] The tear-off portion 12 is connected to the outer wall of the annular body 11 and extends outward from the outer wall of the annular body 11. For example, the tear-off portion 12 can be designed as a thin plate or other structure that is easy for the user to apply force to, and its shape can be teardrop-shaped. Optionally, friction portions 121 can be provided on the surface of the tear-off portion 12 to increase the friction during tearing, making it easier to apply external force to destroy the strength-reducing portion 13. For example, the friction portions 121 can be multiple points, multiple protruding fine ridges, or a cross-shaped mesh structure, etc.

[0045] When two collars 1 are provided, a connecting part 2 is provided between the two collars 1, and the two ends of the handle can be connected to different positions of the connecting part 2; when three or more collars 1 are provided, a connecting part 2 is provided between each pair of adjacent collars 1, and the two ends of the handle 3 can be connected to different connecting parts 2. For example, the connecting part 2 can be a strip-shaped plate structure.

[0046] When the buckle of this embodiment is engaged with the container, the annular body 11 forms a complete ring in the circumferential direction, which can reliably lock the container in place. Even if there is shaking during handling, the buckle will not come off the container. By providing a strength-reducing part 13 on the annular body 11 and a tearing part 12 near the strength-reducing part 13, the strength-reducing part 13 can be broken when an external force is applied, causing the annular body 11 to break in the circumferential direction. This allows the collar 1 to be easily removed from the container without the need for other auxiliary tools.

[0047] In some embodiments, such as Figure 3As shown, at least two collars 1 are arranged side by side along the first direction x, the handle 3 is located on one side of the connecting part 2 along the second direction y, and each tearing part 12 is located on the side of the collar 1 away from the handle 3 along the second direction y, the second direction y being perpendicular to the first direction x.

[0048] For example, since multiple tear-off sections 12 are all located on the same side and at the same position on the collar 1, facing the same direction, the strength-reducing section 13 on each ring-shaped body 11 can also be located at the same position. This facilitates the design of multiple collars 1 with the same structural form, reducing the difficulty of mold making. Moreover, by placing multiple tear-off sections 12 on the side away from the handle 3, there is enough space to install the handle 3, and it is convenient for the user to perform tear-off operations.

[0049] In some embodiments, such as Figure 3 As shown, the strength-reducing portion 13 extends radially inclined relative to the annular body 11, and the tearing portion 12 is connected to the area of ​​the annular body 11 where a sharp portion is formed on one side of the strength-reducing portion 13.

[0050] The strength-reducing portion 13 can be elongated and can extend in a straight line or in an arc-shaped inclined direction. When this type of strength-reducing portion 13 is provided on the annular body 11, a sharp portion is formed on one side of the annular body 11 along the circumferential direction at the outer wall, and an obtuse angle portion is formed on the other side at the outer wall. When an external force is applied, the area of ​​the sharp portion of the tearing portion 12 can easily destroy the strength-reducing portion 13, causing the annular body 11 to tear from the outside to the inside along the extension direction of the strength-reducing portion 13.

[0051] In some embodiments, the lifting buckle includes at least three loops 1 spaced apart along a first direction x, the two ends of the handle 3 are connected to different connecting portions 2, and the number of loops 1 located outside the handle 3 along the first direction x is equal. Figure 1 As shown, there are three collars 1, and the two ends of the handle 3 are respectively connected to two connecting parts 2. When more collars 1 are provided, the two ends of the handle 3 should be connected to the connecting parts 2 as close to the outer side as possible.

[0052] In this embodiment, when at least three collars 1 are provided, the two ends of the handle 3 are connected to different connecting parts 2, which can distribute the force more widely when carrying and improve the stability when carrying. Moreover, the number of collars 1 located on the outside of the handle 3 is equal, which makes the weight on both sides of the handle 3 similar when carrying, improves the balance, and makes it less likely to tilt.

[0053] In some embodiments, such as Figure 3As shown, at least two collars 1 are arranged side by side along the first direction x. The connecting part 2 includes a main body section 21 and an offset section 22 that are connected to each other. The offset section 22 is offset relative to the main body section 21 along the second direction y toward the side away from the handle part 3. The second direction y is perpendicular to the first direction x. The end of the handle part 3 is connected to the concave side of the offset section 22, and the connection position is close to the plane where the center line of the at least two collars 1 is located.

[0054] The connecting portion 2 can be a strip-shaped structure with a certain width, and a transition portion can be provided between the main body segment 21 and the offset segment 22 to reduce stress concentration at the connection. For example, the main body segment 21 is symmetrical about the central plane in the second direction. Optionally, the connecting portion 2 can be a strip-shaped structure extending in a straight line.

[0055] This embodiment, by setting an offset section 22 in the connecting part 2 and connecting the end of the handle 3 to the concave side of the offset section 22, facilitates setting the connection position of the handle 3 in a plane close to the center line of at least two collars 1. When the handle is lifted, the force is applied at the center of the collar 1 along the second direction y, making the force more balanced, less prone to tilting when lifted, improving stability, and also improving the comfort of the lifter.

[0056] In some embodiments, the connecting portion 2 includes two main body segments 21, with an offset segment 22 connecting the two main body segments 21. For example, the offset segment 22 is located in the middle region of the connecting portion 2 along the first direction x. With this structure, when the handle 3 is connected to the offset segment 22, the connection position is in the middle of the connecting portion 2, which makes the height of the containers on both sides consistent when carrying, improving the comfort of the person lifting.

[0057] Optionally, in the same connecting part 2, only one main body segment 21 may be provided, so that the offset segment 22 is located near the collar 1.

[0058] In some embodiments, in the second direction y, the width of the offset segment 22 is the same as the width of the main body segment 21. This structure allows the connecting portion 2 to have a consistent width along the extension path, ensuring the overall strength of the connecting portion 2 and preventing breakage at the point where the handle 3 connects to the connecting portion 2.

[0059] In some embodiments, such as Figure 1 As shown, the handle 3 extends at an angle to one side and includes a first section 31 and two second sections 32. The first end of each of the two second sections 32 is connected to the connecting part 2. The two ends of the first section 31 are respectively connected to the second ends of the two second sections 32. Multiple recesses 33 for fingers to grip are arranged side by side on the inner wall of the first section 31, such as arc-shaped recesses 33.

[0060] For example, such as Figure 5 and Figure 6As shown, with the handle attached to the container, the handle 3 extends diagonally upwards. The first segment 31 and the two second segments 32 connect to form a C-shaped structure, and a rounded corner transition can be used at the connection point.

[0061] This embodiment provides a recessed portion 33 on the inner sidewall of the first segment 31 of the handle portion 3, which allows the fingers to be inserted into the recessed portion 33 when the handle is held, thereby improving the comfort of the gripping area and preventing the hand from slipping.

[0062] In some embodiments, on a third direction z extending along the thickness of the annular body 11, the third direction z is perpendicular to the first direction x and the second direction y. The handle 3 extends along the third direction z toward the first side of the annular body 11. A plurality of first positioning protrusions 14 are provided circumferentially at intervals on the surface of the annular body 11 on the first side. A plurality of second positioning protrusions 15 are provided circumferentially at intervals on the surface of the annular body 11 on the second side. The positions of the plurality of first positioning protrusions 14 and the plurality of second positioning protrusions 15 correspond one-to-one. The height of the second positioning protrusion 15 is greater than the height of the first positioning protrusion 14.

[0063] like Figure 4 As shown, this is a front view of the lifting buckle. Each annular body 11 has three first positioning protrusions 14 spaced circumferentially along its first side. The first positioning protrusions 14 slightly protrude from the surface of the annular body 11. Figure 3 As shown, this is a schematic diagram of the back of the lifting buckle. Each annular body 11 has three second positioning bosses 15 spaced circumferentially on its second side. The second positioning bosses 15 can be designed as solid or hollow structures.

[0064] In this embodiment, when the lifting fasteners are stored or when they are automatically fitted onto containers during production, multiple lifting fasteners can be stably stacked along the third direction z (i.e., the thickness direction of the annular body 11). During stacking, the second positioning boss 15 of the upper lifting fastener rests on the first positioning boss 14 of the lower lifting fastener. Because the areas of the first positioning boss 14 and the second positioning boss 15 are small, high processing accuracy can be achieved, and the positioning stability during placement can be improved through multi-point support positioning.

[0065] Secondly, this disclosure provides a container assembly, including: at least two containers, each container including a containment body and a lid, the lid being used to close the opening of the containment body; and a lifting buckle as described in the above embodiment, wherein at least two collars 1 are correspondingly fitted onto the at least two containers at positions below the lid. Figure 2 The diagram shows the structure of the upper part of the lifting fastener; the circled portion represents the structure of the tear-off part 12. Figure 1 The diagram shown is a schematic of the lower structure of the lifting fastener.

[0066] When the buckle of this embodiment is engaged with the container, the annular body 11 forms a complete ring in the circumferential direction, which can reliably lock the container in place. Even if there is shaking during handling, the buckle will not come off the container. By providing a strength-reducing part 13 on the annular body 11 and a tearing part 12 near the strength-reducing part 13, the strength-reducing part 13 can be broken when an external force is applied, causing the annular body 11 to break in the circumferential direction. This allows the collar 1 to be easily removed from the container without the need for other auxiliary tools.

[0067] Furthermore, when at least three loops 1 are provided, the two ends of the handle 3 are connected to different connecting parts 2, which can further disperse the force when carrying and improve the stability when carrying; moreover, the number of loops 1 located on the outside of the handle 3 is equal, which makes the weight on both sides of the handle 3 similar when carrying, improves the balance, and makes it less likely to tilt.

[0068] Furthermore, an offset section 22 is provided in the connecting part 2, and the end of the handle 3 is connected to the concave side of the offset section 22. This is beneficial to set the connection position of the handle 3 in a plane close to the center line of at least two collars 1. When the handle is lifted, the force is applied at the center of the collar 1 along the second direction y, making the force more balanced. It is not easy to tilt when the handle is lifted, thus improving stability and enhancing the comfort of the lifter.

[0069] Furthermore, by providing a recessed portion 33 on the inner sidewall of the first section 31 of the handle portion 3, the fingers can be inserted into the recessed portion 33 when the handle is held, thereby improving the comfort of the grip area and preventing the hand from slipping.

[0070] While this disclosure has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this disclosure. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This disclosure is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
