Technical Field
[0001] The utility model relates to the technical field of a paper bag with a handle for takeout, etc., in particular to an anti-tampering sealed paper bag with an anti-opening function and an inside-sticking and outside-turning type. Background Art
[0002] Currently, paper bags used for takeout on the market are generally required to have certain insulation and sealing functions. Conventional paper bags with handles have an open opening, which prevents them from being sealed after loading with food and prevents the contents from accidentally falling out of the bag. Furthermore, open-top paper bags are susceptible to environmental influences such as weather, humidity, and temperature during takeout delivery, leading to contamination or degradation of the contents. In response to the open-top structure, some conventional sealing methods for takeout paper bags involve simply taping the middle of the bag opening with adhesive tape or simply nailing it shut. However, this method still struggles to achieve optimal sealing performance and lacks a certain degree of anti-theft protection, as consumers are unlikely to detect the bag opening being opened and then taped or nailed back together during delivery.
[0003] In response to the above situation, the applicant applied for a prior patent for "A paper bag with an inner-sticked and outer-flipped seal" with Chinese patent application number CN202223000570.X. The prior patent document realizes a two-layer closed structure of the bag opening by arranging a sealing sticker 5 with a three-stage distribution structure and a first long strip of self-adhesive sticker 8 on the outer sticker of the handle 4, and arranges a wavy cutting line 10 on the sealing sticker to achieve that when the sealing sticker is destroyed, the wavy cutting line is also destroyed, thereby achieving the purpose of anti-theft. However, in actual use, the patent solution of the prior patent document still has some shortcomings that need to be improved, as follows: (1) When the bag opening is tightly sealed by the sealing sticker and the first long strip of self-adhesive to form a double-sealed closed state, when the bag opening needs to be opened to take out the food in the hand-held paper bag, the bag opening is opened by tearing off the part of the hand-held outer sticker between the hand-held outer sticker and the first long strip of self-adhesive (that is, the hand-held outer sticker is torn off horizontally to separate it from the first long strip of self-adhesive to achieve the purpose of opening the bag); in this way, in the process of tearing off the hand-held outer sticker, it is difficult to tear it off in one go, and it needs to be torn off multiple times. In addition, the torn hand-held outer sticker is often interrupted, the torn gap is incomplete, and there are many torn paper scraps and paper debris, etc., which makes it inconvenient and troublesome to tear off the hand-held outer sticker, and the bag opening cannot be easily opened. In addition, the paper scraps and paper debris from tearing off the hand-held outer sticker multiple times are likely to fall into the hand-held paper bag from the bag opening and contaminate the food. (2) The wavy cutting line is used for anti-theft, to prevent someone from directly tearing the bottom of the sealing sticker and the first long strip of adhesive to open the bag; however, in actual use, since the wavy cutting line is a continuous cutting line, when the sealing sticker is slowly and carefully torn off from the bottom, the wavy cutting line can be left undamaged during the process of tearing off the sealing sticker. In this way, someone with ulterior motives can use this method to open the bag and re-stick it without being noticed by consumers, resulting in a decrease in the anti-theft performance of the paper bag.
[0004] Therefore, in order to avoid the shortcomings of the existing technology, it is necessary to make certain improvements to the existing technology, so as to develop a sealed paper bag with a handle that can basically seal the bag opening after the load is placed in the bag, can quickly open the bag opening by tearing it once, is easy to operate, and can remind consumers whether the bag has been opened through an irreversible anti-theft structure. Summary of the Invention

[0025] Example 1
[0026] The embodiment 1 describes a tamper-proof sealed paper bag with an inner seal and an outer flip, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, it includes a paper bag body 1, a handle rope 2 fixedly attached to the inner side surface of the top of the paper bag body through an inner handle sticker, a self-adhesive seal sticker 3 fixedly attached to an inner side surface of the top of the paper bag body or fixedly attached to an inner handle sticker, the top of the self-adhesive seal sticker is extended with a self-adhesive seal label sticker 4 which is folded downward to be stored inward or folded upward to be unfolded outward, a release paper 5 covering the self-adhesive seal label sticker is provided on the inner side of the self-adhesive seal sticker, and the inner side of the self-adhesive seal label sticker is coated with self-adhesive 6 to form an adhesive connection with the release paper. The tamper-evident sealed paper bag adopts an inside-out self-adhesive seal sticker structure, which takes into account both simple appearance and easy operation. After the tamper-evident sealed paper bag is manufactured, the paper bag body is in a folded state (that is, when the paper bag body is empty). A folding seam is provided between the self-adhesive seal sticker and the self-adhesive seal label sticker, and the self-adhesive seal label sticker can be folded down through this folding seam. The inner side of the self-adhesive seal sticker below the folding seam is fixed to the inner sticker of the handle of the handle rope by glue. When the paper bag body is not used to load food, the self-adhesive seal label sticker is folded down and placed inside the paper bag body, in a hidden state, so as not to affect the appearance of the tamper-evident sealed paper bag. At the same time, the self-adhesive seal label sticker placed inside the paper bag body can be used to protect the self-adhesive seal label sticker to prevent the release paper from falling off prematurely or the self-adhesive seal label sticker from interlocking and being torn.
[0027] In this embodiment 1, the self-adhesive seal label includes a left label 7 that, after the release paper is torn off, is flipped over the left periphery of the hand strap; a middle label 8 that passes through the hand strap; and a right label 9 that is flipped over the right periphery of the hand strap. The self-adhesive seal label extends upward from the bottom and comprises three spaced-apart sections, one on each side of the hand strap and the other in the center of the corresponding hand strap. To load food into the paper bag, the self-adhesive seal label is simply opened upward, exposing the three sections. The food is then placed into the paper bag, the release paper is torn off, and each section of the label is flipped over to the other side of the bag opening. The self-adhesive seal is then affixed to the surface of the paper bag with adhesive tape to complete the tamper-evident sealed paper bag for food packaging and delivery.
[0028] In this first embodiment, a transversely disposed zipper-type tear line structure 10 is provided between the bottom of the self-adhesive seal label and the connection point with the self-adhesive seal sticker. This structure can be torn and separated from the self-adhesive seal label and the self-adhesive seal sticker. When this tamper-proof sealed paper bag is delivered to the consumer, the zipper design of this zipper-type tear line structure can be used to directly tear the zipper-type tear line structure away from the self-adhesive seal sticker. At this point, the self-adhesive seal label sticker and the self-adhesive seal sticker are no longer connected, effectively separating them. The paper bag's opening is now open, making it easy for the consumer to remove food from the bag and consume it. The three-section label sticker remains attached to the surface of the paper bag via the self-adhesive adhesive.
[0029] In this first embodiment, the adhesive seal label is coated on its inner side at the front end of the zipper-type tear-off structure. This placement of the adhesive ensures that, even after the zipper-type tear-off structure is removed, the seal label remains attached to the outer surface of the paper bag. The seal label is no longer attached to the seal label, but is completely separated, allowing the bag opening to be opened.
[0030] In this embodiment 1, the self-adhesive seal label sticker is further provided with a tamper-evident sharp line 11 at the location where the self-adhesive seal label sticker is applied. A tamper-evident sharp line cut-through structure is provided during the production process of the self-adhesive seal label sticker. This tamper-evident sharp line has at least two unconnected sections. Once the paper bag body is sealed, if someone tears the self-adhesive seal label sticker from the bottom or side, the tamper-evident sharp line structure will be irreversibly damaged, thereby reminding consumers that the self-adhesive seal label sticker has been pulled after being applied to the paper bag body, or that the bag opening of the tamper-evident sealed paper bag has been opened a second time, thereby providing extremely high anti-theft performance and reminding consumers.
[0031] In this first embodiment, the zipper-type tear-off structure comprises multiple transversely spaced tear-off openings 12, each symmetrically arranged above and below. Each opening comprises a straight line opening and an arc-shaped opening that narrows and extends outward at the end of the straight line opening. This zipper-type tear-off structure, consisting of multiple transversely spaced, non-connected tear-off openings, prevents the entire zipper-type tear-off structure from being pulled apart from the adhesive seal by accidentally pulling on the end of the tear-off opening, thus ensuring the integrity of the zipper-type tear-off structure before actual tearing. The upper and lower easy-tear line openings of the easy-tear line opening are symmetrically arranged and not connected to each other, and the straight line opening and the arc opening of each easy-tear line opening are both connected structures; with such a structure, when the zipper-type easy-tear line structure is pulled up for tearing, the straight line openings of the upper and lower easy-tear line openings of the first easy-tear line opening will be torn up first and then gradually to the arc opening. When the arc opening of the first easy-tear line opening is close to being completely torn up (not completely torn apart), due to the inertia of the force, the straight line opening of the subsequent easy-tear line opening is driven by the tearing force and torn up almost at the same time. In this way, an uninterrupted process can be formed in the process of tearing up the zipper-type easy-tear line structure, and the zipper-type easy-tear line structure of each section of the self-adhesive seal label sticker can be smoothly torn off from the self-adhesive seal sticker at one time, thereby achieving the purpose of opening the bag.
[0032] In this embodiment 1, the right side of the zipper-type tear-off structure of the left and middle label stickers is provided with an outwardly protruding tear-off line protruding zipper puller 13. When the zipper-type tear-off structure of the left and middle label stickers is torn, the provided easy-tear line protruding zipper puller allows the label section to be quickly and conveniently torn off. Simply lift the easy-tear line protruding zipper puller with a fingernail, which is convenient and does not hinder the operation of sticking the label section to the paper bag body.
[0033] In this embodiment 1, an indicator arrow 14 is provided on the outer surface of the zipper-type tear-off thread structure, indicating the direction opposite to the direction in which the protruding zipper slider of the tear-off thread is provided. The indicator arrow can intuitively indicate the tearing direction of the zipper-type tear-off thread structure, allowing consumers to quickly and conveniently tear the entire zipper-type tear-off thread structure in the correct direction.
[0034] In this embodiment 1, the anti-tampering pointed line is formed by symmetrical straight line openings at intervals to form a triangular pointed line, and the pointed ends of the anti-tampering pointed line are all facing the ends of the left label sticker, the middle label sticker, and the right label sticker. The straight opening in the lower part of the anti-tampering pointed line is symmetrical and intermittent, while the two straight openings forming a triangle in the upper part are symmetrical and connected at the corners. Such a design is that after the left label sticker, the middle label sticker, and the right label sticker are torn off the release paper and pasted on the surface of the paper bag body, someone tears off the left label sticker, the middle label sticker, and the right label sticker from the end or side and needs to tear off the left label sticker, the middle label sticker, and the right label sticker completely to open the bag. In the process of complete tearing, the anti-tampering pointed line must also be torn, so that the part of the label sticker between the two straight openings spaced in the same direction will also be torn and broken, that is, the anti-tampering pointed line will be damaged once it is torn, and irreversible repair will be formed. After repeatedly pasting the left label sticker, the middle label sticker, and the right label sticker back to the paper bag body, it is easy to detect that the bag has been opened after packaging, so as to remind consumers to be careful, and the bag has extremely strong anti-theft and anti-tampering performance.
[0035] In this embodiment 1, the inner sides of the ends of the left label sticker and the right label sticker are both provided with symmetrically arranged arc chamfers, and the middle label sticker gradually narrows from top to bottom to form a semi-elliptical end.
[0036] The zipper-type tear-off line structure is adopted to realize the separation of the self-adhesive seal sticker and the self-adhesive seal label sticker by tearing off the zipper-type tear-off line structure in one step, thereby achieving the purpose of opening the bag mouth. The one-step operation is very convenient and simple. When tearing off the zipper-type tear-off line structure, no excess paper scraps or the like are left or fall into the paper bag body, and the loaded items will not be affected. In addition, an anti-tampering pointed line is provided at the position where the self-adhesive seal label sticker is coated with the self-adhesive, so that once the self-adhesive seal label sticker is torn from the paper bag body, the self-adhesive seal label sticker will be irreversibly damaged, reminding consumers to pay attention to whether the bag has been opened, greatly improving the anti-theft performance, and basically achieving the anti-theft effect of the paper bag being opened twice.
[0037] The above description is only a preferred embodiment of the present invention and does not constitute any formal limitation on the structure of the present invention. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
