Description

Technical Field

[0001] This application relates to the technical field of packaging, and in particular to a packaging lid. Background Technology

[0002] In the Western fast food industry, as consumers increasingly demand convenience and hygiene, the packaging of snack sets is receiving more and more attention. Packaging containers, due to their low cost, environmental friendliness, and recyclability, have become a common choice for snack set packaging. They not only effectively hold various snacks but also make them convenient for consumers to carry and eat.

[0003] In the past, a round piece of cardboard was typically used as a lid to cover packaged snacks. This type of round cardboard lid is simple to manufacture, inexpensive, and readily available. It can be directly placed over the opening of the packaging container, providing some degree of privacy.

[0004] The existing round cardboard packaging lid has obvious defects. It is not securely attached to the packaging container and can easily fall off during transportation or when the consumer holds the packaging container, thus failing to guarantee food safety. Therefore, further improvement is needed. Utility Model Content

[0005] To address the above problems, this application provides a packaging cap.

[0006] This application provides a packaging cap, which adopts the following technical solution: A packaging cap includes a packaging cap body, wherein a plurality of snap-fit ​​tabs extend circumferentially from the cap body, the plurality of snap-fit ​​tabs being spaced apart, and the free ends of the snap-fit ​​tabs being used to snap into a packaging container so that the packaging cap body is fastened to the packaging container.

[0007] By adopting the above technical solution, the snap-fit ​​pieces extended along the four sides of the packaging cap body are used to snap with the roll structure of the packaging container at their free ends. Specifically, they snap into the gap between the roll structure of the packaging container and the packaging container, thereby enabling the packaging cap body to be stably fastened to the packaging container, effectively reducing the occurrence of the packaging cap falling off, ensuring the stability of the connection between the packaging cap and the packaging container during use, and thus ensuring the safety of the food inside the packaging.

[0008] Preferably, the packaging cover body includes a top plate, a plurality of side plates respectively bent and connected to the periphery of the top plate, and an adhesive plate bent and connected to the ends of the side plates. The snap-fit ​​piece is disposed on the side plate, and the adhesive plate is used to connect with the adjacent side plate.

[0009] By adopting the above technical solution, the packaging cap body is composed of a top plate and several side plates bent and connected to the periphery of the top plate. The snap-fit ​​piece is set on the side plate. This structure allows the snap-fit ​​piece to take advantage of the position and angle of the side plate and the adhesive plate when connecting with the packaging container, so as to ensure the integrity and stability of the packaging cap structure, reduce the separation or loosening of the side plate during use, and thus make the packaging cap better fit on the packaging container, improving the overall performance.

[0010] Preferably, one of the side plates is provided with a snap-fit ​​tab.

[0011] By adopting the above technical solution, and by setting a snap-fit ​​piece on one side plate, and since there are multiple side plates, there are multiple snap-fit ​​pieces, so that the packaging cap can be relatively stably fastened to the packaging container.

[0012] Preferably, one of the side plates is provided with two snap-fit ​​tabs, which are arranged symmetrically.

[0013] By adopting the above technical solution, two snap-fit ​​pieces are symmetrically arranged on one side plate, which makes the fastening of the packaging cap and the packaging container more stable and balanced. Compared with a single snap-fit ​​piece, the two symmetrically arranged snap-fit ​​pieces can apply force evenly from both sides, effectively reducing the possibility of the packaging cap tilting, shaking or even falling off during use, and greatly enhancing the stability of the connection between the packaging cap and the packaging container.

[0014] Preferably, the distance between the free end of the snap-fit ​​tab and the edge of the packaging cap body is greater than or equal to the width of the roll structure of the packaging container.

[0015] Preferably, the free end of the snap-fit ​​tab has a protrusion facing the packaging cap body, and the distance between the protrusion and the edge of the packaging cap body is smaller than the distance between the snap-fit ​​tab and the edge of the packaging cap body.

[0016] By adopting the above technical solution, the free end of the snap-fit ​​piece is provided with a protrusion. The protrusion is used to strengthen the snap-fit ​​piece and the edge of the container. The distance between the protrusion and the packaging cap body is smaller than the distance between the snap-fit ​​piece and the packaging cap body, which can enhance the fastening stability of the packaging cap and the packaging container.

[0017] Preferably, a deformation groove is provided at the connection between the snap-fit ​​piece and the packaging cap body, so that the free end of the snap-fit ​​piece can be bent toward the roll structure of the packaging container.

[0018] By adopting the above technical solution, a deformation groove is opened at the connection between the snap-fit ​​piece and the packaging cap body, so that the free end of the snap-fit ​​piece can be bent toward the packaging cap body under the influence of external force. When the packaging cap is fastened to the packaging container, the snap-fit ​​piece can be more easily snapped into the lower end of the outward folded roll structure of the packaging container due to bending, so as to achieve a stable fastening between the packaging cap and the packaging container and reduce the possibility of the packaging cap falling off.

[0019] Preferably, a lifting tab is provided on the free end of the snap-fit ​​tab away from the packaging cover body.

[0020] By adopting the above technical solution, and by setting up a lifting tab, consumers can pinch and open the packaging cover.

[0021] Preferably, the adhesive plates on two adjacent side plates are bonded together to form a triangular support area, so that the packaging cover body has a three-dimensional structure.

[0022] By adopting the above technical solution, the adhesive plates on two adjacent side plates are bonded together to form a triangular support area, so that the packaging cap body has a three-dimensional structure, thereby enabling the packaging cap to better fit onto the packaging container, ensuring the integrity and stability of the packaging cap structure, and improving the overall performance.

[0023] Preferably, the side plates located on both sides of the adhesive plate are respectively provided with a first crease and a second crease, and the first crease and the second crease intersect at one end near the top plate to form a triangular folding area; there are four side plates, of which two side plates arranged opposite each other are the first side plates and the other two side plates arranged opposite each other are the second side plates. After folding along the first crease and the second crease of the first side plate / second side plate, the second side plate / first side plate abuts against the lower surface of the top plate to form a planar structure.

[0024] By adopting the above technical solution, a first crease and a second crease are respectively set on the side plates on both sides of the adhesive plate of the packaging cap body, and the first crease and the second crease intersect at the end near the top plate to form a triangular folding area. When there are four side plates, two of which are opposite each other as the first side plates and the other two opposite each other as the second side plates, folding along the first crease and the second crease of the first side plate or the second side plate can make the second side plate or the first side plate abut against the lower surface of the top plate, thereby making the packaging cap foldable into a flat structure. This facilitates the storage and transportation of the packaging cap and reduces the space occupied.

[0025] In summary, this application has the following beneficial effects: 1. The snap-fit ​​tab snaps into the gap between the roll structure of the packaging container and the packaging container, thereby enabling the packaging cap to be stably fastened to the packaging container; 2. The design of the spacing between the snap-fit ​​tab and the edge of the cover matches the rolled edge structure, making it more secure; 3. The engagement is further strengthened by providing protrusions on the snap-fit ​​tabs; 4. The packaging lid is folded into a flat structure through the set creases, which facilitates transportation and storage. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1 - Appendix Figure 9 This application will be described in further detail below.

[0029] This application discloses a packaging cap.

[0030] Example 1: A type of packaging lid, as shown Figure 1 , Figure 2The packaging includes a lid body 1, with several snap-fit ​​pieces 2 extending circumferentially along its edge. These snap-fit ​​pieces 2 are spaced apart, and their free ends engage with the lower end of the outwardly folded-out structure 31 of the packaging container 3. Specifically, they engage in the gap between the rolled-out structure and the packaging container 3, allowing the lid body 1 to be fastened to the packaging container 3. The snap-fit ​​between the snap-fit ​​pieces 2 and the rolled-out structure 31 of the packaging container 3 provides good fixing force, effectively reducing the likelihood of the lid falling off and ensuring the stability of the connection between the lid and the packaging container 3 during use, thereby ensuring the safety of the food inside the packaging.

[0031] The packaging lid body 1 may only include a top plate 11. The top plate 11 may be circular, and its shape can be customized according to requirements. It should be noted that at least two snap-fit ​​tabs 2 are provided to facilitate fastening the packaging lid body 1 to the packaging container 3. In another embodiment, the top plate 11 may be a regular polygon, such as... Figure 3 The square arrangement shown can have two snap-fit ​​pieces 2, positioned on opposite sides of the top plate 11, or four snap-fit ​​pieces 2. Alternatively, two snap-fit ​​pieces 2 can be positioned on each of the two or four sides of the top plate 11, symmetrically arranged, such as... Figure 4 As shown.

[0032] Furthermore, a lifting tab 23 is provided on the free end of the snap-fit ​​tab 2 away from the packaging cover body 1, so that the consumer can pinch it to open the packaging cover body 1.

[0033] Back Figure 1 , Figure 2 Furthermore, the free end of the snap-fit ​​piece 2 is designed to be fastened to the lower end of the roll-up structure 31 of the packaging container 3. In this embodiment, a snap-fit ​​groove 21 is provided between the free end of the snap-fit ​​piece 2 and the packaging cover body 1 so that the roll-up structure 31 of the packaging container 3 can pass through.

[0034] Furthermore, the distance between the free end of the snap-fit ​​piece 2 and the packaging cap body 1 can be greater than or equal to the width of the roll structure of the packaging container 3, so as to snap into the gap between the roll structure of the packaging container 3 and the packaging container 3.

[0035] Furthermore, to enhance the fastening stability between the packaging cap and the packaging container 3, in this embodiment, the free end of the snap fastener 2 is provided with a protrusion 22 in the direction of the packaging cap body 1, and the distance between the protrusion 22 and the packaging cap body 1 is smaller than the distance between the snap fastener 2 and the packaging cap body 1.

[0036] Furthermore, the upper end face of the packaging cover body 1 is provided with a placement groove 12, that is, the upper surface of the top plate 11 is provided with a placement groove 12 for placing the sauce box. The top plate 11 has a fixing piece 121 protruding from the inner peripheral wall of the placement groove 12 to abut against the side wall of the sauce box. Regarding the number of fixing pieces 121, several fixing pieces 121 are arranged at intervals around the axis of the placement groove 12, with at least two. In this embodiment, four fixing pieces 121 are specifically shown.

[0037] Furthermore, a ventilation area 4 is provided around the packaging cover body 1. The ventilation area 4 can be a ventilation hole / ventilation groove that runs through the top plate 11. In this embodiment, a ventilation hole is specifically shown, which is located near the side of the top plate 11.

[0038] The implementation principle of a packaging cap according to an embodiment of this application is as follows: the snap-fit ​​pieces 2 extended around the perimeter of the packaging cap body 1 snap onto the lower end of the outwardly folded roll structure 31 of the packaging container 3, which enables the packaging cap body 1 to be stably fastened to the packaging container 3, effectively reducing the occurrence of the packaging cap falling off, ensuring the stability of the connection between the packaging cap and the packaging container 3 during use, and thus ensuring the safety of the food inside the packaging.

[0039] Example 2: Reference Figure 5 The difference from Embodiment 1 is that the packaging cover body 1 also includes several side plates 13 that are bent and connected to the periphery of the top plate 11, and adhesive plates 14 that are bent and connected to the ends of the side plates 13. A snap-fit ​​piece 2 is disposed on the side plate 13, and one snap-fit ​​piece 2 can be disposed on each side plate 13, or as shown below. Figure 6 As shown, two snap-fit ​​pieces 2 are provided on one side plate 13. The two snap-fit ​​pieces 2 are arranged symmetrically, and the specific arrangement depends on the requirements.

[0040] The adhesive plates 14 are used to connect with adjacent side plates 13. In this embodiment, four adhesive plates 14 are provided. For ease of explanation, two oppositely arranged side plates 13 are designated as first side plates 131, and the other two oppositely arranged side plates 13 are designated as second side plates 132. Regarding the four adhesive plates 14, two adhesive plates 14 are located at both ends of one of the first side plates 131 / second side plates 132, and the other two adhesive plates 14 are located at both ends of the other first side plate 131 / second side plate 132. Alternatively, the four adhesive plates 14 can be respectively located at one end of each of the four side plates 13.

[0041] By providing an adhesive plate 14 and connecting it to adjacent side plates 13, the various side plates 13 of the packaging cap body 1 can be firmly joined together, ensuring the integrity and stability of the packaging cap structure, reducing the separation or loosening of the side plates 13 during use, and thus allowing the packaging cap to better fasten onto the packaging container 3. Figure 7As shown, this improves overall performance.

[0042] It should be noted that the adhesive plates 14 on the two adjacent side plates 13 are bonded together to form a triangular support area, making the packaging cap body 1 a three-dimensional structure, so that the packaging cap can be better fastened to the packaging container, ensuring the integrity and stability of the packaging cap structure and improving the overall performance.

[0043] Since the adhesive plate 14 and the side plate 13 are already bonded before transportation, they are arranged in a three-dimensional manner, which is relatively inconvenient for transportation. Therefore, to facilitate transportation, the side plates 13 located on both sides of the adhesive plate 14 are further provided with a first fold 6 and a second fold 7, respectively. The first fold 6 and the second fold 7 intersect at the end near the top plate 11 to form a triangular folding area 8. Since there are four side plates 13, after folding along the first fold 6 and the second fold 7 of the first side plate 131 / second side plate 132, the second side plate 132 / first side plate 131 abuts against the lower surface of the top plate 11 to form a planar structure 5, such as... Figure 8 As shown.

[0044] It should be noted that when there are two snap-fit ​​pieces 2 on each side, any one snap-fit ​​piece 2 can be folded, and the piece can be folded outwards without fastening. The remaining seven snap-fit ​​pieces can be fastened. Furthermore, different snap-fit ​​pieces 2 have different flavor markings, meaning there can be a total of four flavors. When a flavor is selected, that snap-fit ​​piece 2 is folded outwards without fastening. Ventilation holes / ventilation grooves can be opened on the side plate 13 or the top plate 11 to form a ventilation area 4. When the side plate 13 is bent and snapped onto the packaging container 3 by the snap-fit ​​piece 2, a certain gap is left between the top plate 11 and the packaging container 3, which can also form a ventilation area 4. The specific settings are based on the requirements.

[0045] Compared to having only a snap-fit ​​piece 2 on the top plate 11, the above structure allows the packaging cover body 1 to more stably fasten to the packaging container 3, enhancing the stability of the fastening between the packaging cover and the packaging container 3 and reducing the possibility of the packaging cover falling off.

[0046] Example 3: Reference Figure 9 The difference from Embodiment 1 is that a deformation groove 24 is provided at the connection between the snap-fit ​​piece 2 and the packaging cover body 1, so that the free end of the snap-fit ​​piece 2 can be bent toward the packaging cover body 1. This embodiment can be used in combination with other embodiments.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
