Description

Technical Field

[0001] This utility model belongs to the field of packaging tableware technology, and specifically refers to a packaging container. Background Technology

[0002] With the ever-accelerating pace of life, food delivery has become a popular dining option for many, and the booming food delivery culture has also led to the development of tableware such as takeout containers. Currently, in existing takeout tableware, only the container lid has a handle structure to facilitate separation of the lid and the container body. For example, utility model application number 202222624588.0 discloses a container that includes a bottom, an inner liner, and a lid, wherein the inner liner is set inside the bottom to form the container body, and the container body and the lid are interference-fitted, with a handle structure on the lid.

[0003] However, the box body and lid are fixed together by an interference fit, without any other auxiliary fixing methods. When the packaged tableware is squeezed, the lid is easy to separate from the box body, and the connection is not strong enough. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a packaging container that uses a handle to make the container body and container lid more securely connected.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A packaging container includes a container body and a container lid, characterized in that: the upper part of the container body is provided with an outwardly protruding lower lifting lug, the outer edge of the container lid is provided with an outwardly protruding upper lifting lug, the lower lifting lug is provided with a buckle hole, the lower side of the upper lifting lug is provided with a buckle body that can be inserted into the buckle hole, the lower end of the buckle body is enlarged to form a limiting part, the maximum diameter of the limiting part is greater than the inner diameter of the buckle hole, and after the upper lifting lug and the lower lifting lug are fastened together, the limiting part is located below the buckle hole.

[0007] This packaging container features a lower lifting lug on the outside of the container body and an upper lifting lug on the top of the container lid. The upper and lower lifting lugs are fixedly connected by a buckle on the upper lifting lug and a buckle hole on the lower lifting lug, thereby enhancing the connection between the container body and the container lid.

[0008] In the aforementioned packaging container, the diameter of the lower part of the limiting part gradually increases from bottom to top, and the lower part of the limiting part is conical or hemispherical.

[0009] Since the diameter of the buckle hole is smaller than the maximum diameter of the limiting part, the design of the lower part of the limiting part gradually increasing in diameter from bottom to top can play a guiding role, making it easier for the limiting part to pass through the buckle hole and play a limiting role.

[0010] In one of the aforementioned packaging containers, the upper lifting lug has several punches spaced apart along the outer side of the buckle, and there is a connection point between two adjacent punches.

[0011] The design of the aforementioned perforation and narrow connection point ensures that the connection point is torn off when the packaging container is opened. This disposable top-lifting ear structure allows users to immediately perceive whether the takeout has been opened during the process from preparation to delivery, thus understanding the condition of the takeout upon arrival. It also solves the problem that the diameter of the limiting part is larger than the buckle hole, making it impossible for the buckle to separate smoothly from the bottom-lifting ear.

[0012] In one of the above-mentioned packaging containers, the upper edge of the container body is folded outward to form a flange, and the edge of the container lid is provided with an annular sealing groove with the opening facing downward. The flange can be inserted into the annular sealing groove along with the upper edge of the container body. The lower lifting ear is fixedly connected to the lower edge of the flange, and the upper lifting ear is fixedly connected to the lower edge of the annular sealing groove.

[0013] The upper edge of the container body is inserted into the annular sealing groove of the container lid to achieve an interference fit connection. The structure is simple, the connection is convenient, and the connection is highly stable.

[0014] In the aforementioned packaging container, an outwardly protruding guide protrusion is formed on the outer wall of the flange. The guide protrusion is located above the lower lifting lug and is fixedly connected to the upper side of the lower lifting lug. An outwardly protruding guide groove is formed on the outer wall of the annular sealing groove. The guide groove is located above the upper lifting lug. The upper lifting lug is provided with an opening communicating with the guide groove. The guide protrusion can be inserted into the guide groove from below. When the guide protrusion is aligned with the guide groove, the buckle body of the upper lifting lug is aligned with the buckle hole of the lower lifting lug.

[0015] The aforementioned guide protrusion and guide groove work together to ensure that the container body and container lid are smoothly fastened together. When in use, rotate the container lid to align the guide protrusion and guide groove vertically, and then press down on the container lid. The guide protrusion can be inserted into the guide groove. The upper edge of the container body is interference-fitted with the annular sealing groove of the container lid. At the same time, the limiting part at the lower end of the fastener passes through the fastening hole, thereby achieving the fixation between the container body and the container lid.

[0016] In one of the aforementioned packaging containers, the upper lifting lug is provided with anti-slip stripes, anti-slip protrusions, or anti-slip grooves.

[0017] The aforementioned anti-slip stripes, anti-slip protrusions, or anti-slip grooves increase the friction between the user's hand and the top handle when separating the container lid from the container body, making it easier to grip the top handle smoothly.

[0018] In the aforementioned packaging container, a connecting boss protruding upward is formed in the middle of the upper side of the lower lifting ear, and a lower groove that cooperates with the connecting protrusion is provided on the lower side of the lower lifting ear. The buckle hole is provided on the connecting boss and communicates with the lower groove, and the limiting part can pass through the buckle hole and be located in the lower groove.

[0019] The design of the connecting boss on the lower handle enhances the structural strength of the lower handle around the buckle hole, thus providing better support when the limiting part passes through the buckle hole, preventing the lower handle from deforming under pressure during compression. The limiting part being located in the lower groove also prevents the lower handle from being touched and breaking off from the buckle body during transportation, which helps to enhance the stability of the container body and container lid after fastening. The design of the connecting boss also enhances the overall structural strength of the lower handle. When the user moves this packaging container through the lower handle, the lower handle is not easily deformed and has better resistance to deformation. At the same time, the design of the lower groove also makes it easier for fingers to grip.

[0020] In one of the aforementioned packaging containers, the lower lifting lug is provided with several reinforcing ribs.

[0021] The aforementioned reinforcing rib design further enhances the deformation resistance of the lower pull tab, while also serving as an anti-slip structure to increase finger grip.

[0022] In the aforementioned packaging container, the lower edge of the flange folds outward to form a support step, the support step is connected to the lower lifting lug, and the outer edges of the support step and the lower lifting lug have an upwardly protruding rim. The lower edge of the outer wall of the annular sealing groove can be placed on the support step. When the container body and the container lid are fastened together, the lower edge of the outer wall of the annular sealing groove is lower than the upper edge of the rim. The upper lifting lug is placed on the lower lifting lug and is located within the groove-shaped space enclosed by the rim at the lower lifting lug.

[0023] The aforementioned design of the lower support step and the surrounding edge not only increases the leak-proof performance of this packaging container, but also enhances the structural strength and deformation resistance of the container body at the folded edge.

[0024] In the aforementioned packaging container, there is one or more lower lifting ears. When there are two or more lower lifting ears, the lower lifting ears are arranged in a circular array with the central axis of the container body as the center, and the upper lifting ears are arranged in a one-to-one correspondence with the lower lifting ears.

[0025] The number of lower and upper handles on this packaging container is generally set to one, two, three, or four. The more upper and lower handles there are, the stronger and more stable the connection between the container body and the container lid will be.

[0026] Compared with the prior art, the technical effects of this utility model are as follows:

[0027] In this invention, a lower lifting lug is provided on the outside of the container body, and an upper lifting lug is provided on the upper side of the container lid. The upper and lower lifting lugs are fixedly connected by the fastener on the upper lifting lug and the fastener hole on the lower lifting lug, thereby achieving the purpose of strengthening the connection between the container body and the container lid by using the connection of the upper and lower lifting lugs.

[0037] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0038] This packaging container includes a container body 2 and a container lid 1. The upper part of the container body 2 is provided with an outwardly protruding lower lifting lug 21, and the outer edge of the container lid 1 is provided with an outwardly protruding upper lifting lug 11. The lower lifting lug 21 is provided with a buckle hole 211, and the lower side of the upper lifting lug 11 is provided with a buckle body 111 that can be inserted into the buckle hole 211. The lower end of the buckle body 111 is enlarged to form a limiting part 112. The maximum diameter of the limiting part 112 is greater than the inner diameter of the buckle hole 211. After the upper lifting lug 11 and the lower lifting lug 21 are fastened, the limiting part 112 is located below the buckle hole 211. In this packaging container, a lower lifting lug 21 is provided on the outside of the container body 2, and an upper lifting lug 11 is provided on the upper side of the container lid 1. The upper lifting lug 11 and the lower lifting lug 21 are fixedly connected by the fastener 111 on the upper lifting lug 11 and the fastener hole 211 on the lower lifting lug 21. This achieves the purpose of strengthening the connection between the container body 2 and the container lid 1 by connecting the upper and lower lifting lugs 21.

[0039] like Figure 4 and Figure 5 As shown, the diameter of the lower part of the limiting part 112 gradually increases from bottom to top. The lower part of the limiting part 112 is conical or hemispherical. Since the diameter of the buckle hole 211 is smaller than the maximum diameter of the limiting part 112, the design of the lower part of the limiting part 112 gradually increasing from bottom to top can play a guiding role, making it easy for the limiting part 112 to pass through the buckle hole 211 and play a limiting role. Figure 6 As shown, the upper handle 11 has several perforations 113 spaced apart along the outer side of the buckle body 111, and there is a connection point 114 between two adjacent perforations 113. The design of the perforations 113 and the narrow connection point 114 ensures that the connection point 114 is torn off when the packaging container is opened. This disposable upper handle 11 structure allows users to see at a glance whether the takeout has been opened during the process from preparation to delivery, thus understanding the condition of the takeout upon arrival; it also solves the problem that the diameter of the limiting part 112 is larger than the buckle hole 211, and the buckle body 111 cannot be smoothly separated from the lower handle 21.

[0040] like Figure 4 As shown, the upper edge of the container body 2 folds outward to form a flange 22. The edge of the container lid 1 is provided with an annular sealing groove 12 with the opening facing downward. The flange 22 can be inserted into the annular sealing groove 12 along with the upper edge of the container body. The lower lifting lug 21 is fixedly connected to the lower edge of the flange 22, and the upper lifting lug 11 is fixedly connected to the lower edge of the annular sealing groove 12. The upper edge of the container body 2 and the annular sealing groove 12 of the container lid 1 are connected by an interference fit. The structure is simple, the connection is convenient, and the connection stability is high.

[0041] Furthermore, an outwardly protruding guide protrusion 23 is formed on the outer wall of the flange 22. The guide protrusion 23 is located above the lower lifting ear 21 and is fixedly connected to the upper side of the lower lifting ear 21. An outwardly protruding guide groove 13 is formed on the outer wall of the annular sealing groove 12. The guide groove 13 is located above the upper lifting ear 11. The upper lifting ear 11 is provided with an opening that communicates with the guide groove 13. The guide protrusion 23 can be inserted into the guide groove 13 from below. When the guide protrusion 23 is aligned with the guide groove 13, the buckle body 111 of the upper lifting ear 11 is aligned with the buckle hole 211 of the lower lifting ear 21. The aforementioned guide protrusion 23 and guide groove 13 work together to ensure that the container body 2 and the container lid 1 can be smoothly fastened together. When in use, rotate the container lid 1 to make the guide protrusion 23 and guide groove 13 automatically align themselves, and then press down on the container lid 1. The guide protrusion 23 can be inserted into the guide groove 13. The upper edge of the container body 2 is press-fitted with the annular sealing groove 12 of the container lid 1. At the same time, the limiting part 112 at the lower end of the fastener 111 passes through the fastening hole 211, thereby achieving the fixation between the container body 2 and the container lid 1.

[0042] like Figure 1-4 As shown, the upper handle 11 is provided with anti-slip stripes 115, anti-slip protrusions, or anti-slip grooves. The design of the above-mentioned anti-slip stripes 115, anti-slip protrusions, or anti-slip grooves can increase the friction between the hand and the upper handle 11 when the user separates the container lid 1 and the container body 2, making it easier to grasp the upper handle 11 smoothly.

[0043] like Figure 7 and Figure 8 As shown, the upper side of the lower lifting ear 21 has an upwardly protruding connecting boss 212 formed in the middle, and the lower side of the lower lifting ear 21 has a lower groove 213 that cooperates with the connecting protrusion. The buckle hole 211 is provided on the connecting boss 212 and communicates with the lower groove 213. The limiting part 112 can pass through the buckle hole 211 and be located in the lower groove 213. The design of the connecting boss 212 on the lower lifting lug 21 enhances the structural strength of the lower lifting lug 21 around the buckle hole 211, thus providing better support when the limiting part 112 passes through the buckle hole 211, preventing the lower lifting lug 21 from deforming under pressure during the compression process. The limiting part 112 being located in the lower groove 213 also prevents the lower lifting lug 21 from being touched and breaking off from the buckle body 111 during transportation, which is beneficial to enhancing the stability of the container body 2 and the container lid 1 after fastening. The design of the connecting boss 212 also enhances the overall structural strength of the lower lifting lug 21. When the user moves the packaging container through the lower lifting lug 21, the lower lifting lug 21 is not easily deformed and has better resistance to deformation. At the same time, the design of the lower groove 213 also makes it easier for fingers to grip.

[0044] Furthermore, the lower lifting lug 21 is provided with several reinforcing ribs 214. The design of the aforementioned reinforcing ribs 214 can further enhance the deformation resistance of the lower lifting lug 21, and at the same time, as an anti-slip structure, it can increase the grip strength of the fingers.

[0045] Furthermore, the lower edge of the flange 22 folds outward to form a support step 24, which communicates with the lower lifting lug 21. The outer edges of the support step 24 and the lower lifting lug 21 have upwardly protruding rims 25. The lower edge of the outer wall of the annular sealing groove 12 can be placed on the support step 24. When the container body 2 and the container lid 1 are fastened together, the lower edge of the outer wall of the annular sealing groove 12 is lower than the upper edge of the rim 25. The upper lifting lug 11 is placed on the lower lifting lug 21 and located within the groove-shaped space enclosed by the rim 25 at the lower lifting lug 21. The design of the lower support step 24 and the rim 25 not only increases the leak-proof performance of this packaging container but also enhances the structural strength and deformation resistance of the flange 22 of the container body 2.

[0046] like Figure 1-3 As shown, there is one or more lower handles 21. When there are two or more lower handles 21, they are arranged in a circular array around the central axis of the container body 2. The upper handles 11 are arranged in a one-to-one correspondence with the lower handles 21. The number of lower handles 21 and upper handles 11 in this packaging container is generally set to one, two, three, or four. The more upper and lower handles 21 there are, the stronger and more stable the connection between the container body 2 and the container lid 1 will be.

[0047] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection defined by the claims of the present utility model.
