Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, specifically a pull-out self-opening food packaging box. Background Technology

[0002] In today's fast-paced life, the convenience, airtightness, and safety of food packaging have become core consumer concerns. Currently, most food packaging boxes on the market (such as potato chips, nuts, and other snack packaging) use traditional tear-off plastic bags, snap-on cardboard boxes, or sealed structures that require tools to open, which presents several drawbacks: First, opening traditional boxed foods is complicated. Taking tubular potato chips as an example, it requires three steps: "opening the plastic lid → peeling off the aluminum foil seal → pulling out the plastic tray." This not only makes the opening process complex but also generates unnecessary plastic waste. Second, some packaging lacks effective tamper-evident labels, making it impossible for consumers to visually determine whether the product has been resealed or tampered with, posing a food safety risk.

[0003] Based on this, a pull-out self-opening food packaging box is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0004] The purpose of this invention is to provide a pull-out self-opening food packaging box to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A pull-out self-opening food packaging box includes an outer packaging box body, a pull-out lid, an inner box, and a sealing film. The inner box is slidably connected to the inner wall of the outer packaging box body. A panel is fixedly connected to the side wall of the inner box. The pull-out lid is fixedly connected to the side wall of the panel. A sealing film is adhered to the opening of the inner box. One end of the sealing film is adhered to the inner wall of the outer packaging box body.

[0006] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: the sealing film adheres to the outer packaging box body to a greater degree than the sealing film adheres to the inner box.

[0007] In one alternative: the cross-section of the outer packaging box is octagonal.

[0008] In one alternative: an observation hole is provided on the side wall of the outer packaging box body, a marking plate is fixedly connected to the outer packaging box body at the position of the observation hole, and an anti-tampering strip is adhered to the side wall of the inner box, the anti-tampering strip sliding between the marking plate and the outer packaging box body.

[0009] In one alternative: the label is marked with an "opened" label.

[0010] In one alternative: the tamper-evident strip is marked with an "unopened" label at the location of the observation hole.

[0011] In one alternative: an elastic pressure plate is fixedly connected to the side wall of the marking plate, and the elastic pressure plate abuts against the tamper-proof strip.

[0012] In one alternative: the inner box is provided with chamfers.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a pull-out design, allowing consumers to easily open the inner box with a single pull of the lid. The sealing film automatically peels off under the pull, achieving a "one-step opening" experience. No tools are needed, and the operation is as simple as pulling out a drawer. The entire opening process is smooth, ritualistic, and fun, greatly enhancing ease of use, making it particularly suitable for various scenarios such as outdoor activities and office settings.

[0014] This invention utilizes an observation hole, a marking plate, an tamper-evident strip, and an elastic pressure plate. When the product is unopened, consumers can see the "Unopened" mark on the tamper-evident strip through the observation hole. When the inner box is pulled out and opened, the tamper-evident strip moves inward and separates from the anti-counterfeiting area. Due to the low rigidity of the tamper-evident strip and the limiting effect of the elastic pressure plate, the tamper-evident strip cannot be reset even if the inner box is pushed back. At this time, the "Opened" mark on the marking plate will be displayed at the observation hole. Consumers can intuitively identify whether the product has been resealed, effectively eliminating the risk of tampering and ensuring food safety.

[0015] The sealing film of this invention adopts an integrated adhesive structure with the outer packaging box body. Even if it is torn open, it will not detach from the outer packaging box, thus avoiding the plastic waste caused by the sealing film falling off separately. This is in line with the concept of environmental protection and reduces environmental pollution. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-4 As shown, the pull-out self-opening food packaging box includes an outer packaging box body 1, a pull lid 2, an inner box 5, and a sealing film 4. The inner box 5 is slidably connected to the inner wall of the outer packaging box body 1. A panel 3 is fixedly connected to the side wall of the inner box 5. The pull lid 2 is fixedly connected to the side wall of the panel 3. The sealing film 4 is glued to the opening of the inner box 5. One end of the sealing film 4 is glued to the inner wall of the outer packaging box body 1.

[0023] When the consumer pulls out the lid 2, the inner box 5 containing the food is pulled out along with the lid 2. One end of the sealing film 4 covering the surface of the inner box 5 is tightly connected to the outer packaging box body 1, so that when the consumer pulls out the lid 2, the sealing film 4 can be gradually peeled off from the inner box 5 under the action of the pulling force. Finally, when the inner box 5 is pulled all the way down, the sealing film 4 is completely peeled off from the inner box 5, and the food is directly presented to the consumer, achieving the effect of opening and eating in one step.

[0024] Consumers pull the lid 2 → the inner box 5 moves accordingly → the sealing film 4 is pulled open → the potato chips can be eaten directly. The whole process is as simple as pulling out a "drawer", which can be operated with one hand without the need for violent tearing. The opening process is ritualistic and fun. If you can't finish them, you can push them back in. It is suitable for short-term resealing and preservation, maintaining food hygiene and reducing plastic waste.

[0025] The sealing film 4 is integrated with the outer packaging box body 1, ensuring that the sealing film 4 will not detach from the outer packaging box body 1 after being torn, thus reducing waste generation.

[0026] In one embodiment, the degree of adhesion between the sealing film 4 and the outer packaging box body 1 is greater than the degree of adhesion between the sealing film 4 and the inner box 5.

[0027] In one embodiment, the outer packaging box body 1 has an octagonal cross-section. The octagonal cylindrical structure is more rigid than the quadrilateral cylinder, reducing losses during warehousing and transportation; the obtuse angle design of the octagon minimizes the risk of stress concentration in irregularly shaped packaging; with the same material cost, the cylinder can provide the largest internal volume (the most capacity), and with the same internal capacity, the cylinder will occupy the largest external volume (the most space-consuming). The octagonal cylinder is at the balance point between theoretical optimization and practical needs.

[0028] In one embodiment, an observation hole 8 is provided on the side wall of the outer packaging box body 1, and a marking plate 7 is fixedly connected to the outer packaging box body 1 at the position of the observation hole 8. An anti-tampering strip 6 is adhered to the side wall of the inner box 5, and the anti-tampering strip 6 slides between the marking plate 7 and the outer packaging box body 1.

[0029] In one embodiment, the label plate 7 is marked with an "opened" label.

[0030] In one embodiment, the tamper-proof strip 6 is marked with an "unopened" label at the location of the observation hole 8.

[0031] One end of the tamper-evident strip 6 is inserted between the marking plate 7 and the outer packaging box body 1, while the other end is tightly connected to the bottom of the inner box 5. The marking plate 7 is marked with the words "opened". When the inner box 5 is pulled out, the tamper-evident strip 6 moves accordingly. After moving a certain distance, it leaves the anti-counterfeiting area of ​​the outer packaging box body 1. Due to the low rigidity of the tamper-evident strip 6 and the narrow distance between the marking plate 7 and the outer packaging box body 1, even if the inner box is pushed back in, the tamper-evident strip 6 will not return to its original position. At this time, consumers can identify whether the product has been resealed by seeing the words "unopened".

[0032] In one embodiment, an elastic pressure plate 9 is fixedly connected to the side wall of the marking plate 7, and the elastic pressure plate 9 abuts against the tamper-evident strip 6. The elastic pressure plate 9, which has the ability to deform elastically, narrows the opening, making it more difficult to push the pulled-out tamper-evident strip 6 back in.

[0033] In one embodiment, the inner box 5 is provided with chamfers.

[0034] The above embodiments disclose a pull-out self-opening food packaging box, the specific working principle and process of which are as follows: When the consumer pulls out the lid 2, the inner box 5 containing the food is pulled out along with the lid 2. One end of the sealing film 4 covering the surface of the inner box 5 is tightly connected to the outer packaging box body 1, so that when the consumer pulls out the lid 2, the sealing film 4 can be gradually peeled off from the inner box 5 under the action of the pulling force. Finally, when the inner box 5 is pulled all the way down, the sealing film 4 is completely peeled off from the inner box 5, and the food is directly presented to the consumer, achieving the effect of opening and eating in one step.

[0035] One end of the tamper-evident strip 6 is inserted between the marking plate 7 and the outer packaging box body 1, while the other end is tightly connected to the bottom of the inner box 5. The marking plate 7 is marked with the words "opened". When the inner box 5 is pulled out, the tamper-evident strip 6 moves accordingly. After moving a certain distance, it leaves the anti-counterfeiting area of ​​the outer packaging box body 1. Due to the low rigidity of the tamper-evident strip 6 and the narrow distance between the marking plate 7 and the outer packaging box body 1, even if the inner box is pushed back in, the tamper-evident strip 6 will not return to its original position. Combined with the elastic pressure plate 9 with elastic deformation capability, the opening is narrowed, making it even more difficult to push the pulled-out tamper-evident strip 6 back in. At this time, consumers can identify whether the product has been resealed by seeing the words "unopened".

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
