Abstract
Description
Technical Field
[0001] The present invention relates to the field of engineering, and more particularly to a confidential zipper bag.
Background Art
[0002] Generally, a confidential zipper bag is designed so that it cannot be opened in a normal way, i.e., the zipper body cannot be separated by pulling or distorting the opening of the bag, in order to keep the documents or articles stored inside confidential until the zipper bag reaches the recipient, who is the only person the sender intends to disclose the contents to. Therefore, there are mechanisms to prevent access to the internal space of the zipper bag in various ways, which include, for example, mechanisms that help the recipient notice that the confidential zipper bag has been opened before it reaches the recipient, such as the zipper bag breaking instead of the zipper separating when the opening of the bag is pulled apart.
[0003] However, current confidential zipper bags, such as Patent Document 1, as shown in FIG. 1, have a small base of the zipper and a small connection point between the male zipper and the female zipper. Therefore, although the male zipper and the female zipper cannot be separated from each other by a force acting linearly, for example, by pulling them apart, users feel that there is a problem that the male zipper and the female zipper may slip apart when the zipper is distorted or tampered with. As a result, a third party can access the documents or articles stored inside and close the confidential zipper bag again as before without the recipient knowing that the confidential zipper bag has been opened before receipt. Thus, it becomes impossible to use the confidential zip bag to its full potential and satisfy the intended purpose.

Patent Document 1
[0005] Accordingly, the present invention attempts to overcome the above-mentioned problems by providing a secure zipper bag in one aspect, comprising a total of at least two male structures, each including a first snap fitting portion and a second snap fitting portion, the first and second snap fitting portions being formed such that their tips have arrow-shaped cross-sections extending from the first and / or second snap fitting portions toward the opposing snap fitting portion; a female structure positioned at the snap fitting portion opposite each of the corresponding male structures, having a U-shaped structure that wraps around the sagittal tip of the male structure, with its tip bent back toward the tip of the male structure; and at least two complementary structures formed at the first and / or second snap fitting portions between the tips of the female structures of the snap fitting portions opposite the first and / or second base portions, extending toward the opposing base portions.
[0006] Therefore, the airtight zipper bag according to this invention includes at least three connecting points between the two snap-fitting portions, providing a secure connection between the zippers. The invention also provides a complementary structure, which in turn prevents tampering while more efficiently limiting distortion by third parties.
[0007] Furthermore, according to another embodiment, the first and second bases of the first and second snap-fitting portions are formed to be thicker than the other areas of the first and second bases, respectively. This makes it more difficult to distort and separate the male and female zippers.
[0008] Therefore, this invention can prevent the male and female zippers from slipping apart when the zipper is distorted or tampered with. A third party cannot access the documents or articles stored inside the secure zipper bag and re-close the zipper without the recipient knowing that the zipper bag was opened before receipt. Thus, the user can use the secure zipper bag to the fullest extent of its potential and for its intended purpose. [Brief explanation of the drawing]

[Figure 8] This shows a cross-section of a zipper in another embodiment of the present invention. [Figure 9] This shows a cross-section of a zipper in another embodiment of the present invention. [Modes for carrying out the invention]
[0010] The embodiments of this invention will be described in detail with reference to the attached drawings.
[0011] In one embodiment of the present invention, as shown in Figure 2, the airtight zipper bag includes a bag body 1 having an internal space formed by two walls. An opening 2 is attached at the upper end of the bag body 1, through which an object can pass into the bag body to be stored inside, and a bag end 3 is a closed end at the bottom of the bag body 1.
[0012] As shown in Figure 3, the opening 2 has a first zipper 100 and a second zipper 200 that run parallel to the opening 2 across the zipper bag. The first zipper 100 consists of a first base 101 and a first snap fitting portion 102. The first base 101 is connected to the first inner wall of the opening 2, and the first snap fitting portion 102 is connected to the first base 101. Similarly, the second zipper 200 consists of a second base 201 that is connected to the second inner wall of the opening, and a second snap fitting portion 202 that is connected to the second base 201. The second snap fitting portion 202 has a structure that allows it to fit and connect to the first snap fitting portion 102. When connected together, this prevents access to the internal space inside the zipper bag. When separated, this allows access to the internal space inside the zipper bag. Additionally, the first snap fitting portion 102 and the second snap fitting portion 202 are flexible and can deflect in response to the force acting on the first zipper 100 and the second zipper 200.
[0013] Furthermore, the first snap-fit portion 102 and the second snap-fit portion 202 are mainly composed of a male structure, a female structure, and a complementary structure. More specifically, the first snap-fit portion 102 and the second snap-fit portion 202 include a total of at least two male structures 113, 213, which are formed such that their tips have arrow-shaped cross-sections extending from the first snap-fit portion 102 and / or the second snap-fit portion 202 toward the opposing snap-fit portion. According to one embodiment of this specification, as shown in Figure 4, the first snap-fit portion 102 has one male structure 113, and the second snap-fit portion 202 has two male structures 213.
[0014] The first snap-fit portion 102 and the second snap-fit portion 202 further include female structures 114, 214 positioned in the snap-fit portion to face the corresponding male structures 113, 213, respectively, characterized in that the female structures have a U-shaped structure that wraps around the sagittal ends of the male structures 113, 213, and the ends of the female structures 114, 214 are bent back toward the ends of the male structures 113, 213. According to one embodiment of this specification, as shown in Figure 4, the first snap-fit portion 102 has two female structures 114 as U-shaped structures that wrap around the sagittal ends of the male structures 213 of the two second snap-fit portions 202. Furthermore, the ends of the female structures 114 are bent back toward the ends of the male structures 213 and connect to the sagittal ends of the male structures 213. Therefore, it can be seen that the first snap fitting portion 102 has one male structure 113 formed between two female structures 114, and each female structure 114 is formed from a male structure 113 on each side and one arm of the female structure 114 extending from the first base portion 101. In contrast, the second snap fitting portion 202 has one female structure 214 positioned between two male structures 213, and the female structure 214 is formed from the structure of the two male structures 213. When the female structure 214 is aligned with the male structure 113 of the first snap fitting portion 102 and fitted, the sagittal tip of the male structure 213 of the second snap fitting portion 202 wraps around and connects with the sagittal tip of the male structure 113 of the first snap fitting portion 102.
[0015] Furthermore, the first snap-fit portion 102 and the second snap-fit portion 202 further include at least two complementary structures 215, which are formed in the first snap-fit portion 102 and / or the second snap-fit portion 202 between the first base portion 101 and / or the second base portion 201 and the tips of the female structures 114, 214 of the opposing snap-fit portion, and extend toward the opposing base portion. According to one embodiment of the present invention, as shown in Figure 4, on the side of the second snap-fit portion 202 there are two complementary structures 215 that extend from a position between the second base portion 201 and the ends of the arms of the two female structures 114 of the first snap-fit portion 102 and extend toward the first base portion 101. Therefore, the complementary structure 215 is characterized by protruding to support the arm of the female structure 114, thereby limiting zipper distortion and preventing tampering at the end of the arm of the female structure 114.
[0016] Therefore, the airtight zipper bag according to the first embodiment of the present invention has a total of four connection points between the first zipper 100 and the second zipper 200, namely two points between the tip of the female structure 114 and the sagittal tip of the male structure 213, and two points between the sagittal tip of the male structure 113 and the sagittal tip of the male structure 213, which firmly interlock and connect the first zipper 100 and the second zipper 200 to each other. Combined with having at least two complementary structures 215 as described above, this prevents tampering through the gap between the zipper and the base of the zipper while limiting the distortion of the zipper. As a result, even if the zipper is distorted or tampered with, the separation of the zipper can be effectively prevented.
[0017] Furthermore, as shown in FIG. 5, the first base portion 101 and the second base portion 201 are formed such that the base regions 116 and 216 of the first snap-fitting portion 102 and the second snap-fitting portion 202 are thicker than the other regions of the first base portion 101 and the second base portion 201, respectively. Additionally, on each side, there are two ridges 117 and 217 on the outer surfaces of the first base portion 101 and the second base portion 201. These ridges 117 and 217 will strengthen the bases of the first zipper 100 and the second zipper 200, and can more firmly prevent the zipper from being distorted.
[0018] Therefore, the present invention can prevent the first zipper 100 and the second zipper 200 from slipping apart even when the zipper is distorted or tampered with. A third party cannot access the documents or articles inside the confidential zipper bag and re-close the zipper without the recipient knowing that the confidential zipper bag has been opened before receipt. Therefore, the user can use the confidential zipper bag to its full potential according to its intended purpose.
[0019] Next, as shown in FIG. 6, the bag end 3 includes a breakable area 31, a bag end zipper assembly 32, and a ridge 33.
[0020] The breakable area 31 is connected to the wall of the bag body 1 and is positioned slightly above the bottom 4 of the bag. When the breakable area 31 is broken, a gap is created, allowing access to the internal space of the bag body 1. In an embodiment of the present invention, the breakable area 31 is characterized by having two perforation lines horizontally arranged at positions on the same horizontal plane on both sides of the wall of the bag end 3 at a certain distance from the bottom 4 of the bag.
[0021] Located above the breakable area 31 along the axis of the bag body 1 is the attached bag end zipper assembly 32. This bag end zipper assembly 32 includes a male zipper 321 that connects to one inner wall of the bag end 3 and a female zipper 332 that connects to the other inner wall of the bag end 3, and has a structure that allows it to match and connect to the male zipper 321. In one embodiment of the present invention, as shown in Figure 6, the male zipper 321 connects to the inner wall on the same side as the first snap fitting portion 102, and the female zipper 322 connects to the inner wall on the same side as the second snap fitting portion 202.
[0022] The bag end 3 further includes a projection 33 attached to the inner and outer walls of the bag end 3 at a position between the breakable area 31 and the bag end zipper assembly 32, the projection 33 including two first projections 331 positioned on the outer wall on the same side as the female or male zipper of the bag end zipper assembly 32. In one embodiment of the present invention, the first projection is on the same side as the male zipper 321 of the bag end zipper 32, and the two second projections 332 are positioned on the inner wall on the same side as the first projection 331, at a position related to the first projection 331 in such a way that the second projections 332 support the force acting on the first projection 331 by the user's fingers. A third projection 333 is positioned on the inner wall opposite to the second projections 332, i.e., on the same side as the female zipper 332 of the bag end zipper 32, and positioned between the two second projections 332. The fourth projection 334 is positioned on the outer wall on the same side as the third projection 333, at a location related to the third projection 333 in such a way that the force acting on the fourth projection 334 by the user's finger is supported by the third projection 333.
[0023] Therefore, when a user wishes to access an object stored inside the sealed zipper bag, it is not possible to open the zipper bag by peeling apart the first zipper 100 and the second zipper 200 at the opening of the bag. On the other hand, a user can open the bag by using their fingers to grasp and compress both the first protrusion 331 and the fourth protrusion 334, and breaking the bag at the breakable area 31 until an opening is formed. The second protrusion 332 and the third protrusion 333 support the force of the user's hand and move toward each other until the third protrusion 333 is aligned within the gap between the two second protrusions 332. Subsequently, the user applies torque to move the first protrusion 331 and the fourth protrusion 334 in opposing directions, that is, pushing the first protrusion 331 downward along the axis of the bag body 1 and pushing the fourth protrusion 334 upward along the axis of the bag body 1 (towards the opening 2), or pushing the first protrusion 331 upward along the axis of the bag body 1 and pushing the fourth protrusion 334 downward along the axis of the bag body 1. This application of sliding torque creates opposing forces between the second protrusion 332 and the corresponding third protrusion 333. These opposing forces are transmitted through the wall of the bag body 1 to the bag end zipper assembly 32, pushing and separating the male zipper 321 and the female zipper 322, so that the user can finally take out the object stored inside.
[0024] The bag end 3 of this invention allows the user to quickly open a closed zipper bag without the need for any further tools. Furthermore, if the breakable area 31 has already been broken before the zipper bag reaches the recipient, this serves as a warning that the stored items may have been accessed before reaching the recipient.
[0025] Next, as shown in Figure 7A, the opening 2 further includes an anti-lock structure 4, which can be separated from the zipper bag and, as shown in Figure 7B, can be sandwiched between the first zipper 100 and the second zipper 200. The anti-lock structure 4 is a flap extending from the wall of the bag body 1 above the first zipper 100 or the second zipper 200 and running along the entire length of the first zipper 100 or the second zipper 200. The anti-lock structure 4 and the wall of the bag body are connected by perforations 401 that run linearly across the width of the zipper bag. In one embodiment of the present invention, the anti-lock structure 4 is a flap extending from the wall of the bag body 1 above the first zipper 100 and running along the entire length of the first zipper 100, and the anti-lock structure 4 and the wall of the bag body are connected by perforations 401 that run linearly across the width of the zipper bag.
[0026] Therefore, the user can fold the anti-lock structure 4 inward towards the opening 2 so that it is positioned between the first zipper 100 and the second zipper 200. This is to prevent the first zipper 100 and the second zipper 200 from being accidentally inserted into and connected to each other. When the user places an object into the bag body 1 and compresses the first zipper 100 and the second zipper 200 to connect and secure them together, the user can peel the anti-lock structure 4 away from the bag body 1 along the perforation 401.
[0027] Furthermore, in another embodiment of the present invention, as shown in Figure 8, the first snap-fit portion 102 comprises two male structures 113 and one female structure 114 as a U-shaped structure formed by the two male structures 113 and subsequently positioned between both male structures 113. The second snap-fit portion 202 has two female structures 214 having a U-shaped structure that wraps around the sagittal ends of the male structures 113 of the two first snap-fit portions 102. The ends of the female structures 214 are bent back toward the ends of the male structures 113, wrapping around and connecting to the sagittal ends of the male structures 113. The second snap-fit portion 202 has one male structure 213 formed between the two female structures 214, and it can be seen that each female structure 214 is formed from a male structure 213 on each side and one arm of the female structure 214 extending from the second base 201. Furthermore, the first snap-fit portion 102 further includes two complementary structures 115 formed between the first base portion 101 and the tip of the female structure 214 of the second snap-fit portion 202, extending toward the tip of the female structure 214. Thus, the presence of these complementary structures 115 is equivalent to compressing the arm of the female structure 214 and keeping it connected to the end of the male structure 113, thereby further limiting distortion and preventing tampering at the end of the arm of the female structure 214. Furthermore, the first base portion 101 and the second base portion 201 are formed such that the base regions 116, 216 of the first snap-fit portion 102 and the second snap-fit portion 202 are thicker than the other regions of the first base portion 101 and the second base portion 201, respectively. Also, on each side, the outer surfaces of the first base portion 101 and the second base portion 201 have two protrusions 117, 217. These protrusions 117 and 217 reinforce the bases of the first zipper 100 and the second zipper 200, making it more robust to prevent the zippers from becoming distorted.
[0028] In another embodiment of the present invention, as shown in Figure 9, the first snap-fit portion 102 consists of one male structure 113 and one female structure 114 having a U-shaped structure formed from one side of the male structure 113 and an arm of the female structure, which wraps around the sagittal end of the male structure 213 of the second snap-fit portion 202. The tip of the female structure 114 is bent back toward the tip of the male structure 213 and similarly connects to the sagittal end of the male structure 213. The second snap-fit portion 202 consists of one male structure 213 and one female structure 214 having a U-shaped structure formed from one side of the male structure 213 and an arm of the female structure, which wraps around the sagittal end of the male structure 113 of the first snap-fit portion 102. The tip of the female structure 214 is bent back toward the tip of the male structure 113 and connects to the sagittal end of the male structure 113.
[0029] Furthermore, the first snap-fit portion 102 further includes a first complementary structure 115 and a second complementary structure 118. The first complementary structure 115 is embossed from the first base 101 and extends into the tip of the female structure 214 of the second snap-fit portion 202. The second complementary structure 118 is formed to extend from the base 116 of the first snap-fit portion 102 at a position between the first complementary structure 115 and the arm of the female structure 214 of the second snap-fit portion 202, and extends to surround the arm of the female structure 214. Similarly, the second snap-fit portion 202 further includes the first complementary structure 215 and the second complementary structure 218. The first complementary structure 215 is embossed from the second base 201 and extends into the tip of the female structure 114 of the first snap fitting 102, while the second complementary structure 218 is formed to extend from the base 216 of the second snap fitting 202 at a position between the first complementary structure 215 and the arm of the female structure 114 of the first snap fitting 102, and extends to surround the arm of the female structure 114. Thus, the first complementary structures 115, 215 and the second complementary structures 118, 218 limit the distortion of the zipper and provide more reliable control over the connection between the male and female structures. Furthermore, on each side, the outer surfaces of the first base 101 and the second base 201 have two protrusions 117, 217. These protrusions 117 and 217 add thickness to the bases of the first zipper 100 and the second zipper 200, making it possible to more firmly prevent the zippers from becoming distorted.
[0030] To obtain a secure zipper bag capable of preventing the male and female zippers from slipping apart even if the zipper is distorted or tampered with, several modifications can be clearly understood, within the scope and spirit of the present invention as evident in the appended claims, in addition to the various embodiments described in detail herein, and these modifications can be made by those skilled in the art of secure zipper bags.
