Description

Field of the invention

[0001] The invention relates to the field of engineering, in particular to a confidential ziplock bag. Background of the invention

[0002] Generally, the confidential ziplock bag is designed to be impossible to open by normal methods, that is, the bag's opening cannot be pulled or twisted to separate the ziplock body, so as to keep the documents or items stored inside confidential until the ziplock bag reaches the recipient, who is the only person the sender intends to disclose the documents or items. Therefore, there is a mechanism to prevent access to the interior of the ziplock bag in various ways, including the mechanism to help the recipient notice that the confidential ziplock bag has been opened before it reaches the recipient, for example, when pulling apart the bag's opening, the ziplock is not separated, but the ziplock bag is torn, etc.

[0003] The current confidential ziplock bag, such as Thai patent application number 1301007211 filed in Fig. 1, however, has a small ziplock base with a small attachment point between the male and female ziplocks. As a result, users have encountered a problem that even male and female zippers cannot be separated by a straight-line force, such as pulling them apart, but male and female zippers may slide apart if the zippers are twisted or tampered with. As a result, a third party may access the documents or items stored inside and reseal the confidential ziplock bag as before, without the recipient knowing that the confidential ziplock bag was opened before receipt, making it impossible to fully utilize the confidential ziplock bag and achieve its intended purpose. Summary of the invention

[0004] Therefore, the present invention aims to overcome the problems described above by providing a confidential ziplock bag according to one aspect, comprising a first latch and a second latch, wherein the first latch and the second latch in total comprise at least two male structures formed such that a tip has an arrow-shaped cross-section extending from the first latch and / or the second latch toward the opposite latch; a female structure positioned on the latch opposite each of the corresponding male structures and having a U-shaped structure wrapping around the arrowhead of the male structure, the tip of the female structure being bent back toward the tip of the male structure;and at least two complementary structures formed on the first latch and / or the second latch at the position between the first base and / or the second base and the tip of the female structure of the opposite latch and extending to the opposite base;

[0005] Therefore, the confidential ziplock bag according to the present invention includes at least three fastening points between the two snap fasteners, ensuring secure fastening between the zippers. The present invention also provides complementary structures that can prevent tampering while more effectively restricting twisting by third parties.

[0006] Furthermore, according to another aspect, the first base and the second base of the first latch and the second latch, respectively, are formed thicker than other portions of the first base and the second base. This makes it difficult to twist and separate the male and female snap fasteners.

[0007] Therefore, the present invention can prevent the male and female ziplocks from sliding apart if the ziplocks are twisted or tampered with. Third parties cannot access the documents or items stored in the confidential ziplock bag and reseal the ziplock without the recipient knowing that the ziplock bag has been opened before receiving it. This allows a user to fully utilize the confidential ziplock bag for its intended purpose. Short description of the drawing Fig. Figure 1 shows a confidential ziplock bag currently available.

Detailed description of the invention

[0008] Embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0009] In one embodiment of the present invention, as described in Fig. As shown in Figure 2, the confidential ziplock bag comprises the bag body 1, which has an internal space formed by two walls. The opening 2 is located at the top end of the bag body 1, allowing items to enter the bag body through the opening 2 for storage. The bag end 3 is the closed end at the bottom of the bag body 1.

[0010] As in Fig. 3, the first snap fastener 100 and the second snap fastener 200 are located at the opening 2 and run parallel to the opening 2 across the ziplock bag. The first snap fastener 100 consists of the first base 101 and the first snap fastener 102. The first base 101 is attached to the first inner wall of the opening 2, and the first snap fastener 102 is attached to the first base 101. Similarly, the second snap fastener 200 consists of the second base 201, which is attached to the second inner wall of the opening, and the second snap fastener 202, which is attached to the second base 201. The second snap fastener 202 has a structure that conforms to and can be attached to the first snap fastener 102. When attached together, it prevents access to the interior of the ziplock bag. When separated, it allows access to the interior of the ziplock bag.In addition, the first snap-in 102 and the second snap-in 202 are flexible and bendable according to the forces acting on the first snap-in 100 and the second snap-in 200.

[0011] Furthermore, the first latch 102 and the second latch 202 primarily consist of a male structure, a female structure, and a complementary structure. More specifically, the first latch 102 and the second latch 202 comprise a total of at least two male structures 113, 213, which are shaped such that a tip has an arrow-shaped cross-section extending from the first latch 102 and / or the second latch 202 toward the opposite latch. According to one embodiment of the present description, as shown in Fig. 4, the first grid 102 has one male structure 113 and the second grid 202 has two male structures 213.

[0012] The first latch 102 and the second latch 202 further comprise the female structure 114, 214 positioned at the latch opposite each of the corresponding male structures 113, 213, characterized in that it has a U-shaped structure that wraps around the arrowhead of the male structure 113, 213, and that the tip of the female structure 114, 214 is bent back to the tip of the male structure 113, 213. According to one embodiment of the present description, as in Fig. As shown in Figure 4, the first latch 102 has two female structures 114, such as the U-shaped structure, which wraps around the arrowhead of the male structure 213 of the two second latches 202. Furthermore, the tip of the female structure 114 is bent back toward the tip of the male structure 213 and fixed to the arrowhead of the male structure 213. Accordingly, it can be seen that the first latch 102 has a male structure 113 formed between two female structures 114, each of the female structures 114 being formed from the male structure 113 on each side and an arm of the female structure 114 extending from the first base 101. Meanwhile, the second latch 202 has a female structure 214 positioned between the 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-in 102, the arrowhead of the male structure 213 of the second snap-in 202 is held and secured to the arrowhead of the male structure 113 of the first snap-in 102.

[0013] In addition, the first latch 102 and the second latch 202 further comprise at least two complementary structures 215 formed on the first latch 102 and / or the second latch 202 at the position between the first base 101 and / or the second base 201 and the tip of the female structure 114, 214 of the opposite latch and extending towards the opposite base. According to an embodiment of the present invention, as shown in Fig. As shown in Figure 4, there are two complementary structures 215 on the side of the second latch 202, extending from the position between the second base 201 and the end of the arm of the two female structures 114 of the first latch 102 and extending toward the first base 101. This complementary structure 215 is therefore characterized by protruding to support the arm of the female structure 114, which limits the rotation of the snap fastener and prevents engagement with the end of the arm of the female structure 114.

[0014] Therefore, it can be seen that the confidential ziplock bag according to the first embodiment of the present invention has a total of 4 attachment points between the first zip fastener 100 and the second zip fastener 200, that is, 2 points between the tip of the female structure 114 and the arrowhead of the male structure 213 and 2 points between the arrowhead of the male structure 113 and the arrowhead of the male structure 213, so that the first zip fastener 100 and the second zip fastener 200 are firmly clamped and attached to each other, together with the presence of the at least two complementary structures 215 as described above, will limit the twisting of the zip fastener while preventing tampering through the gap between the zip fastener and the base of the zip fastener.As a result, the snap fastener can be effectively prevented from separating even if the snap fastener is twisted or tampered with.

[0015] In addition, as in Fig. 5, the first base 101 and the second base 201 are formed thicker in the base region 116, 216 of the first snap 102 and the second snap 202, respectively, than other regions of the first base 101 and the second base 201. In addition, two ridges 117, 217 are provided on each side of the outer surfaces of the first base 101 and the second base 201. These ridges 117, 217 reinforce the base of the first snap fastener 100 and the second snap fastener 200 and can more firmly prevent the snap fastener from twisting.

[0016] Thus, the present invention can prevent the first ziplock 100 and the second ziplock 200 from sliding apart, even if the ziplock is twisted or tampered with. A third party cannot access the documents or items inside the confidential ziplock bag and reseal the ziplock without the recipient knowing that the confidential ziplock bag was opened prior to receipt. This allows the user to fully utilize the confidential ziplock bag for its intended purpose.

[0017] As in Fig. As shown in Figure 6, the bag end 3 consists of the tear-off section 31, the pressure closure arrangement 32 and the ridge 33.

[0018] The tear-off section 31 is characterized by being attached to the wall of the bag body 1 and positioned slightly above the bottom 4 of the bag. When the tear-off section 31 is torn, a gap is created that allows access to the interior of the bag body 1. In one embodiment of the present invention, the tear-off section 31 is characterized by having two perforated lines arranged horizontally on the same plane on both sides of the wall of the bag end 3 and at a position spaced from the bottom 4 of the bag.

[0019] At the position above the tear-off portion 31 along the axis of the bag body 1, the snap fastener assembly 32 is installed. This snap fastener assembly 32 comprises a male snap fastener 321 attached to one inner wall of the bag end 3, and a female snap fastener 332 attached to the other inner wall of the bag end 3 and having a structure corresponding to and attachable to the male snap fastener 321. In one embodiment of the present invention, as shown in Fig. 6, the male snap fastener 321 is attached to the inner wall on the same side as the first snap fastener 102 and the female snap fastener 322 is attached to the inner wall on the same side as the second snap fastener 202.

[0020] The bag end 3 further comprises the ridge 33, which is attached to the inner and outer walls of the bag end 3 at the position between the tear-off section 31 and the snap fastener assembly 32, wherein the ridge 33 comprises two of the first ridges 331, which are positioned on the outer wall on the same side as the female or male snap fastener of the snap fastener assembly 32. In one embodiment of the present invention, it is on the same side as the male snap fastener 321 of the snap fastener assembly 32, two of the second ridges 332 are positioned on the inner wall on the same side as the first ridge 331, in a position relative to the first ridge 331; in such a way that the second ridge 332 bears the forces acting on the first ridge 331 by the user's fingers. A third ridge 333 is arranged on the inner wall opposite the second ridge 332, i.e.on the same side as the female snap fastener 332 of the snap fastener assembly 32, and is located between the two second ridges 332. A fourth ridge 334 is arranged on the outer wall on the same side as the third ridge 333 in a position relative to the third ridge 333 such that the third ridge 333 carries the forces acting on the fourth ridge 334 from the user's fingers.

[0021] Therefore, if the user wants to access an object stored in the closed ziplock bag, the user cannot open the confidential ziplock bag by releasing the first ziplock 100 and the second ziplock 200 at the opening of the bag. However, the user can open the bag by tearing the bag at the tear-off portion 31 until the opening is formed; grasping and pressing the first ridge 331 and the fourth ridge 334 with the fingers; the second ridge 332 and the third ridge 333 withstand the force of the user's hand and move towards each other until the third ridge 333 is aligned in the gap between the two second ridges 332. Then, the user applies a torque and moves the first ridge 331 and the fourth ridge 334 in opposite directions, i.e.It pushes the first ridge 331 downward along the axis of the bag body 1 and the fourth ridge 334 upward along the axis of the bag body 1 (toward the opening 2), or it pushes the first ridge 331 upward along the axis of the bag body 1 and the fourth ridge 334 downward along the axis of the bag body 1. The application of this sliding torque creates an opposing force between the second ridge 332 and the corresponding third ridge 333. This opposing force is transmitted through the wall of the bag body 1 to the snap fastener assembly 32 at the bag end, forcing the male snap fastener 321 and the female snap fastener 322 to disengage, allowing the user to finally reach the object stored therein.

[0022] The bag end 3 according to the present invention allows the user to open the closed ziplock bag quickly and without additional equipment. If the tear-off section 31 is already torn before the ziplock bag reaches the recipient, it also serves as a warning that the object stored therein may be accessed before it reaches the recipient.

[0023] As in Fig. 7A, the opening 2 further comprises an anti-closure structure 4 which can be separated from the ziplock bag and inserted between the first ziplock 100 and the second ziplock 200, as shown in Fig. 7B, the anti-closure structure 4 is a flap extending from the wall of the bag body 1 above the first zip fastener 100 or the second zip fastener 200 and extending the entire length of the first zip fastener 100 or the second zip fastener 200. The anti-closure structure 4 and the wall of the bag body are connected by a perforation 401 extending in a straight line across the width of the zip fastener bags. In one embodiment of the present invention, the anti-closure structure 4 is a flap extending from the wall of the bag body 1 above the first zip fastener 100 and extending the entire length of the first zip fastener 100, the anti-closure structure 4 and the wall of the bag body being connected by the perforation 401 extending in a straight line across the width of the zip fastener bags.

[0024] Thus, the user can fold the anti-lock structure 4 toward the inside of the opening 2 so that the anti-lock structure 4 is positioned between the first snap fastener 100 and the second snap fastener 200. This prevents the first snap fastener 100 and the second snap fastener 200 from being accidentally inserted and fastened to each other. When the user loads the object into the bag body 1 and presses the first snap fastener 100 and the second snap fastener 200 together to connect and fix them, the user can tear the anti-lock structure 4 from the bag body 1 along the perforation 401.

[0025] In a further embodiment of the present invention, as in Fig. As shown in Figure 8, the first snap-in 102 consists of two male structures 113 and one female structure 114 as a U-shaped structure formed by the two male structures 113 and then arranged between the two male structures 113. The second snap-in 202 has two female structures 214 having the U-shaped structure wrapping around the arrowhead of the male structure 113 of the first two snap-in 102s. The tip of the female structure 214 is bent back toward the tip of the male structure 113 and clamped and secured to the arrowhead of the male structure 113. As can be seen, the second snap-in 202 has a male structure 213 formed between two female structures 214, each of the female structures 214 being formed by the male structure 213 on either side, and an arm of the female structure 214 extending from the second base 201.Additionally, the first latch 102 includes two complementary structures 115 formed at the location between the first base 101 and the tip of the female structure 214 of the second latch 202 and extending toward the tip of the female structure 214. This complementary structure 115 therefore resembles compressing the arm of the female structure 214 and holds it secured to the end of the male structure 113, further limiting twisting and preventing tampering with the end of the arm of the female structure 214. In addition, the first base 101 and the second base 201 are formed thicker in the base region 116, 216 of the first latch 102 and the second latch 202, respectively, than other regions of the first base 101 and the second base 201. In addition, the outer surfaces of the first base 101 and the second base 201 have two ridges 117, 217 on each side.These ridges 117, 217 reinforce the base of the first snap fastener 100 and the second snap fastener 200 and can more firmly prevent the snap fastener from twisting.

[0026] In another embodiment of the present invention, as in Fig.As shown in Figure 9, the first latch 102 consists of a male structure 113 and a female structure 114 formed from one side of the male structure 113 and the arm of the female structure, and has the U-shaped structure wrapping around the arrowhead of the male structure 213 of the second latch 202. The tip of the female structure 114 is bent back toward the tip of the male structure 213 and similarly fixed to the arrowhead of the male structure 213. The second latch 202 consists of a male structure 213 and a female structure 214 formed from one side of the male structure 213 and the arm of the female structure, and has the U-shaped structure wrapping around the arrowhead of the male structure 113 of the first latch 102.The tip of the female structure 214 is bent back to the tip of the male structure 113 and attached to the arrowhead of the male structure 113.

[0027] Furthermore, the first latch 102 includes the first complementary structure 115 and the second complementary structure 118. The first complementary structure 115 is embossed from the first base 101 to the tip of the female structure 214 of the second latch 202. The second complementary structure 118 is shaped to extend from the base 116 of the first latch 102 at the location between the first complementary structure 115 and the arm of the female structure 214 of the second latch 202 and is elongated to encompass the arm of the female structure 214. Similarly, the second latch 202 further includes the first complementary structure 215 and the second complementary structure 218.The first complementary structure 215 is formed by the second base 201, which extends into the tip of the female structure 114 of the first latch 102, and the second complementary structure 218 is formed to extend from the base 216 of the second latch 202 at the position between the first complementary structure 215 and the arm of the female structure 114 of the first latch 102, and to extend to encompass the arm of the female structure 114. In this way, the first complementary structure 115, 215 and the second complementary structure 118, 218 limit the twisting of the snap fastener and more securely control the fastening between the male and female structures. Furthermore, the outer surfaces of the first base 101 and the second base 201 have two ridges 117, 217 on each side.These ridges 117, 217 increase the thickness of the base of the first snap fastener 100 and the second snap fastener 200 and can prevent the snap fastener from twisting more.

[0028] In addition to the various embodiments described in detail herein, modifications will be clearly understood and may be made by those skilled in the art of confidential ziplock bags to obtain the confidential ziplock bag that can prevent the male ziplock and the female ziplock from sliding apart even if the ziplock is twisted or tampered with, within the scope and spirit of the invention as appears in the appended claims. Preferred embodiment of the invention
