Description

Secret zipper bag Technical Field The utility model relates to the field of engineering, in particular to a secret zipper bag. Background Generally, a secure zipper pack is designed such that it cannot be opened by conventional means, i.e., the zipper body cannot be separated by pulling or twisting the opening of the pack, so that the document or item stored therein remains secure until the zipper pack is delivered to the recipient for whom the sender only intends to disclose the document or item. Thus, there is a mechanism that prevents access to the interior space of the zipper pack in a variety of ways, including a mechanism that helps the recipient perceive that the secure zipper pack has been opened before it is delivered to the recipient (e.g., the zipper does not separate but the zipper pack is torn when the opening of the pack is opened, etc.). However, as shown in FIG. 1, the zipper base of current security zipper bags (e.g., thailand patent application number 1301007211) is small and the attachment point between the male and female zippers is also small. Accordingly, the user has found a problem that even if the male and female zippers cannot be separated from each other by a force applied in a straight direction (e.g., by pulling them apart), the male and female zippers may still slide apart if the zippers are twisted or broken. Thus, a third party can access the document or item stored therein and then close the secure zippered pouch as before, without the addressee knowing that the secure zippered pouch was opened before receipt, thereby failing to fully function and achieve the intended purpose. Disclosure of utility model Accordingly, the present utility model is directed to overcoming the above-mentioned problems by providing a secure zippered bag, which, according to one aspect, comprises a bag body having an interior space formed by two walls; the bag comprises a bag body, an opening mounted at the top end of the bag body, wherein an article can enter the bag body through the opening to be stored in the bag body, a bag end part which is positioned at the bottom of the bag body and is a closed end part, a first zipper comprising a first base part attached to the first inner wall of the opening and a first clamping part attached to the first base part, and a second zipper comprising a second base part attached to the second inner wall of the opening and a second clamping part attached to the second base part, and the second clamping part is provided with a structure which is matched with the first clamping part and can be attached to the first clamping part, wherein the first clamping part and the second clamping part are flexible and can deflect according to the force applied to the first zipper and the second zipper, the first clamping part and the second clamping part comprise a total of at least two convex structures, the convex structures are formed into an arrow-shaped cross section which extends from the first clamping part and/or the second clamping part towards the opposite clamping part, and a concave structure is positioned at least opposite to the first clamping part and the second clamping part, and a concave structure is formed at the position between the corresponding clamping part and the second clamping part and the concave structure or the concave structure which is positioned at the position opposite to the first clamping part and the second clamping part and the concave structure. In an embodiment, the first snap-in portion has one first male structure formed between two first female structures, wherein each first female structure is formed by the first male structure of each side and one arm of the first female structure extending from the first base, and wherein the second snap-in portion has two second male structures, one second female structure formed by the two second male structures and located between the two second male structures, and two third complementary structures extending from a position between the second base and an end of the arm of the two first female structures of the first snap-in portion and extending towards the first base. In an embodiment, the first base portion and the second base portion are formed thicker at the first base portion region and the second base portion region of the first engaging portion and the second engaging portion, respectively, than at other regions of the first base portion and the second base portion. In an embodiment, the first and second bases have first and second outer ridges on each side at the first and second base regions of the first and second engaging portions, respectively, the ridges protruding from the outer surfaces of the first and second bases. In an embodiment, the bag end comprises a tearable portion allowing access to the interior space of the bag body when the tearable portion is opened, wherein the tearable portion has two perforation lines arranged horizontally on the same plane on both sides of th
