Description

Technical Field

[0001] This utility model relates to the field of takeaway bag technology, and in particular to an anti-opening takeaway bag. Background Technology

[0002] With the fast pace of life, more and more people are choosing to order takeout at lunchtime. Takeout bags play a crucial role in the takeout industry. In recent years, there have been frequent news reports of customers opening their takeout containers, eating a portion of it, and then putting it back in the containers. Therefore, there is an urgent need for takeout bags that are tamper-proof.

[0003] The prior art discloses an innovative anti-opening takeout bag with the patent number CN210047810U, whose structure includes a paper bag body with a fixed paper piece, an adhesive layer, a sealing indentation, a handle loop, and a patch.

[0004] However, the existing technology still has shortcomings in use: when someone pulls the fixing paper to separate the adhesive layer from the paper bag body, the paper bag body can be opened without damaging the sealing indentation on the fixing paper. Therefore, after someone opens the paper bag body in the above way, they can use the adhesive layer on the fixing paper to re-attach the paper bag body. In this way, customers cannot determine whether the takeout has been opened after receiving the takeout. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an anti-opening takeout bag, so that once the takeout bag is opened, it cannot be restored, which can clearly remind customers and effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-opening takeout bag, comprising a takeout bag body with an upper opening and carrying straps on both sides of the opening of the takeout bag body, characterized in that: an adhesive layer is horizontally arranged on one side inside the upper opening of the takeout bag body, and a plurality of micro-dyed capsules are horizontally arranged on the other side inside the upper opening of the takeout bag body, with soft connecting straps corresponding to the inner sides of the plurality of micro-dyed capsules, the soft connecting straps corresponding to the adhesive layer, the interior of the micro-dyed capsules containing dye, and an easy-tear film is provided at the inward-facing opening of the micro-dyed capsules, and the easy-tear film is fixedly connected to the side of the soft connecting straps facing the micro-dyed capsules. When using the bag, the delivery person places the food inside and peels off the backing paper covering the adhesive layer. They then attach the adhesive layer to the flexible straps, sealing the bag's opening. The corresponding straps are pressed together. During this pressing, several prongs contact the marking plate, leaving marks. Simultaneously, the corresponding straps are secured together by the U-shaped Velcro. If the straps are opened and then reattached, because the U-shaped Velcro requires pressing to reattach, and the two straps cannot be perfectly aligned with their initial position, several prongs will leave different marks on the marking plate again. This helps the customer initially determine if the food is safe. If the takeout bag is torn open from both sides, the adhesive force between the adhesive layer and the soft connecting strip is greater than the adhesive force between the micro-dyed capsule and the easy-tear film. Therefore, the adhesive layer will move the soft connecting strip, which in turn will move the easy-tear film until it separates from the micro-dyed capsule. The dye inside the micro-dyed capsule will then flow out, staining the takeout bag. The easy-tear film cannot be reattached to the micro-dyed capsule, meaning it cannot be restored. The dye is non-toxic and harmless. When customers receive their takeout and find color at the opening of the bag, it indicates that the bag has been opened. This provides a clear indication to customers, making it easy for them to determine whether the takeout bag has been opened.

[0007] Furthermore, the takeaway bag has two fastening straps on both sides of the upper opening. These straps are paired and fitted together, with U-shaped Velcro fasteners on the corresponding sides. An indentation marking component is located on the inner side of each strap. The U-shaped Velcro fasteners on the straps can be used to further secure the upper opening of the takeaway bag, and the indentation marking component serves as a marking feature.

[0008] Furthermore, the indentation marking component comprises several barbs located inside the two fastening straps on one side of the takeout bag, and a marking plate located inside the two fastening straps on the other side of the takeout bag. The barbs can leave marks on the marking plate. Because there are several barbs, it is difficult to make the marks completely overlap with the first marks when re-attaching, that is, a mark different from the first mark will be left.

[0009] Furthermore, the inward-facing side of the flexible connecting strip is an easy-to-apply surface. This facilitates adhesion between the flexible connecting strip and the adhesive layer, resulting in a stronger bond.

[0010] Furthermore, the inward-facing side of the adhesive layer is covered with a release liner. The release liner prevents the adhesive layer from sticking to the flexible connector when not in use.

[0011] Furthermore, at least one end of the release liner has an extension tab, the length of which exceeds the length of the adhesive layer. The extension tab facilitates the removal of the release liner.

[0012] Furthermore, the carrying strap is equipped with an arc-shaped anti-squeezing sleeve. The arc-shaped anti-squeezing sleeve is made of rigid material, which can prevent the carrying strap from digging into the hand and causing discomfort when the takeout inside the takeout bag is heavy.

[0013] Furthermore, the micro-dyeing capsules are made of a rigid, pressure-resistant material. This rigidity prevents the micro-dyeing capsules from bursting.

[0014] Based on the above technical solution, the beneficial effects of this utility model's anti-opening takeaway bag achieved through practical application are as follows: This invention utilizes the cooperation between a soft connecting strap, an easy-tear film, a micro-dyed capsule, and an adhesive layer. When the takeout bag is opened, the adhesive layer, through the soft connecting strap, causes the easy-tear film to separate from the micro-dyed capsule, releasing the dye inside the micro-dyed capsule and staining the takeout bag. This allows customers to easily determine whether the takeout bag has been opened. Furthermore, the serrated edges leave marks on the residue sheet, providing customers with double verification of whether the takeout bag has been opened. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-10This embodiment provides a technical solution: an anti-opening takeout bag, including a takeout bag body 1 with an upper opening and carrying straps 2 on both sides of the opening of the takeout bag body 1. The characteristic is that: an adhesive layer 12 is horizontally arranged on one side inside the upper opening of the takeout bag body 1, and a plurality of micro-dyed capsules 11 are horizontally arranged on the other side inside the upper opening of the takeout bag body 1. A soft connecting strap 9 is correspondingly arranged on the inner side of the plurality of micro-dyed capsules 11. The soft connecting strap 9 corresponds to the adhesive layer 12. The micro-dyed capsules 11 contain dye. An easy-tear film 13 is arranged at the inward-facing opening of the micro-dyed capsule 11, and the easy-tear film 13 is fixedly connected to the side of the soft connecting strap 9 facing the micro-dyed capsule 11. In use, the delivery staff places the takeout food into the takeout bag 1 and peels off the anti-adhesive paper 6 covering the adhesive layer 12. Then, they attach the adhesive layer 12 to the soft connecting strap 9. At this point, the opening of the takeout bag 1 is sealed. The corresponding fastening straps 4 are pressed together. During this pressing, several barbs 8 contact the marking plate 10, leaving marks on it. Simultaneously, the corresponding fastening straps 4 are glued together by the U-shaped Velcro 5. If the fastening straps 4 are opened and then reattached, because the U-shaped Velcro 5 requires pressing during attachment, and the two fastening straps 4 cannot be in the same position as when they were first attached, several barbs 8 will leave different marks on the marking plate 10 again, allowing customers to initially determine whether the takeout has been opened. If the takeout bag 1 is torn open from both sides, the adhesive force between the adhesive layer 12 and the soft connecting strip 9 is greater than the adhesive force between the micro-dyed capsule 11 and the easy-tear film 13. Therefore, the adhesive layer 12 will move the soft connecting strip 9, which in turn will move the easy-tear film 13 until the easy-tear film 13 separates from the micro-dyed capsule 11. The dye inside the micro-dyed capsule 11 will flow out, thus staining the takeout bag 1. The easy-tear film 13 cannot be reattached to the micro-dyed capsule 11, meaning it cannot be restored. The dye is a non-toxic and harmless dye. When customers receive the takeout, they will find that the opening of the takeout bag 1 is colored, indicating that the takeout bag 1 has been opened. This serves as a clear reminder to customers, making it easy for them to determine whether the takeout bag 1 has been opened.

[0028] Furthermore, there are two fastening straps 4 on both sides of the upper opening of the takeaway bag 1. The fastening straps 4 are paired and matched, and a U-shaped Velcro 5 is provided on the corresponding side of the fastening straps 4. An indentation marking component is provided on the inner side of the fastening straps 4. The U-shaped Velcro 5 on the fastening straps 4 can be used to fasten the upper opening of the takeaway bag 1 again, and the indentation marking component can be used for marking.

[0029] Furthermore, the indentation marking component consists of several barbs 8 located inside the two fastening straps 4 on one side of the takeaway bag body 1, and a marking plate 10 located inside the two fastening straps 4 on the other side of the takeaway bag body 1. The barbs 8 can leave marks on the marking plate 10. Because there are several barbs 8, it is difficult to make it completely coincide with the first mark when re-attaching, that is, a mark different from the first mark will be left.

[0030] Furthermore, the inward-facing side of the flexible connecting strip 9 is an easy-to-apply surface. This facilitates adhesion between the flexible connecting strip 9 and the adhesive layer 12, resulting in a stronger bond.

[0031] Furthermore, the inward-facing side of the adhesive layer 12 is covered with a release liner 6. The release liner 6 prevents the adhesive layer 12 from sticking to the flexible connecting strip 9 when not in use.

[0032] Furthermore, at least one end of the release liner 6 is provided with an extension piece 7, and the length of the extension piece 7 exceeds the length of the adhesive layer 12. The extension piece 7 serves to facilitate the removal of the release liner 6.

[0033] Furthermore, the carrying strap 2 is equipped with an arc-shaped anti-stretching sleeve 3. The arc-shaped anti-stretching sleeve 3 is made of rigid material, which can prevent the carrying strap 2 from chafing the hand and causing discomfort when the weight of the takeout inside the takeout bag 1 is heavy.

[0034] Furthermore, the micro-dyed capsule 11 is made of a rigid, pressure-resistant material. This rigid, pressure-resistant material prevents the micro-dyed capsule 11 from bursting.

[0035] The working principle of the anti-opening takeout bag provided by this utility model is as follows: When in use, the delivery staff places the takeout food into the takeout bag 1 and peels off the anti-adhesive paper 6 covering the adhesive layer 12. Then, they stick the adhesive layer 12 onto the soft connecting strap 9. At this point, the opening of the takeout bag 1 is sealed. The corresponding fastening straps 4 are pressed together. During the pressing, several barbs 8 come into contact with the marking plate 10, leaving marks on the marking plate 10. At the same time, the corresponding fastening straps 4 are stuck together by the U-shaped Velcro 5. If the fastening straps 4 are opened and then re-stitched, because the U-shaped Velcro 5 must be pressed when sticking together, and the two fastening straps 4 cannot be in the same position as when they were first stuck together, several barbs 8 will leave different marks on the marking plate 10 again, making it easier for customers to initially determine whether the takeout food has been opened. If the takeout bag 1 is torn open from both sides, the adhesive force between the adhesive layer 12 and the soft connecting strip 9 is greater than the adhesive force between the micro-dyed capsule 11 and the easy-tear film 13. Therefore, the adhesive layer 12 will move the soft connecting strip 9, which in turn will move the easy-tear film 13 until the easy-tear film 13 separates from the micro-dyed capsule 11. The dye inside the micro-dyed capsule 11 will flow out, thus staining the takeout bag 1. The easy-tear film 13 cannot be reattached to the micro-dyed capsule 11, meaning it cannot be restored. The dye is a non-toxic and harmless dye. When customers receive the takeout, they will find that the takeout bag 1 has been opened, indicating that the takeout bag 1 has been opened. This serves as a clear reminder to customers, making it easy for them to determine whether the takeout bag 1 has been opened.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
