Description

CONFIDENTIAL ZIPPER BAGField of the Invention

[0001] The invention is related to the engineering field, especially to a confidential zipper bag.Background of the Invention

[0002] Generally, the confidential zipper bag is designed so that it cannot be opened by normal methods, i.e., the opening of the bag cannot be pulled or twisted to separate the zipper body, in order to keep the documents or items stored inside confidential until the zipper 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 accessing to the internal space of the zipper bag in various ways, including the mechanism which helps the recipient to notice that the confidential zipper bag has been opened before it reaches the recipient, e.g., when pulling apart the opening of the bag, the zipper does not separate but the zipper bag is torn, etc.

[0003] However, the current confidential zipper bag, such as the Thai patent application number 1301007211, as shown in, has a small base of the zipper with a small attachment point between the male zipper and the female zipper. Consequently, users have found the problem that even male and female zippers cannot be separated from each other by force acting in a straight line, for example by pulling them apart, male and female zippers can slide apart if the zippers are twisted or tampered. As a result, the third party is able to access the documents or items stored inside and close the confidential zipper bag back as before without the recipient knowing that the confidential zipper bag has been opened before receiving, making it impossible to use the confidential zip bag to its full potential and meet the intended purpose.Summary of the Invention

[0004] Therefore, the present invention aims to overcome the above-described problems by providing a confidential zipper bag, according to one aspect, comprising a first snap-fit and a second snap-fit, where the first snap-fit and the second snap-fit comprise a total of at least two male structures formed in a manner that a tip has an arrow-shaped cross-section extending from the first snap-fit and / or the second snap-fit towards the opposite snap-fit; a female structure, positioned at the snap-fit opposite to each of the corresponding male structure, having a U-shaped structure wrapping around the arrow tip of the male structure, wherein the tip of the female structure is curved back towards the tip of the male structure; and at least two complementary structures formed at the first snap-fit and / or the second snap-fit, at the position between the first base and / or the second base and the tip of the female structure of the opposite snap-fit, and extends towards the opposite base.

[0005] Hence, the confidential zipper bag according to the present invention comprises at least 3 attachment points between the two snap-fits, providing a secure attachment between the zippers. This invention also provides the complementary structures, which as a result, can prevent tampering while limiting the twisting by the third party more efficiently.

[0006] Moreover, according to another aspect, the first base and the second base of the first snap-fit and the second snap-fit, respectively, are formed thicker than other areas of the first base and the second base. This made it more difficult to twist and separate the male and female zippers.

[0007] Therefore, the present invention can prevent the male and female zippers from sliding apart when the zippers are twisted or tampered. The third party cannot access the documents or items stored inside the confidential zipper bag and close the zipper back without the recipient knowing that the zipper bag has been opened before receiving it. Thus, a user can use the confidential zipper bag to its full potential and for its intended purpose.Brief Description of the Drawing

[0018] Embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0019] In an embodiment of the present invention, as shown in, the confidential zipper bag comprises the bag body 1 which has an internal space formed by two walls. The opening 2 is installed at the top end of the bag body 1, wherein objects are able to pass through the opening 2 into the bag body to be stored therein, and the bag end 3 is the closed end at the bottom of the bag body 1.

[0020] As shown in, at the opening 2, there is the first zipper 100 and the second zipper 200 running across the zipper bag parallel to the opening 2. The first zipper 100 consists of the first base 101 and the first snap-fit 102. The first base 101 is attached to the first inner wall of the opening 2 and the first snap-fit 102 is attached to the first base 101. Similarly, the second zipper 200 consists of the second base 201 attached to the second inner wall of the opening and the second snap-fit 202 attached to the second base 201. The second snap-fit 202 has a structure that conforms and is attachable to the first snap-fit 102. When attached together, it prevents access to the internal space inside the zipper bag. When separated, it allows the access to the internal space inside the zipper bag. In addition, the first snap-fit 102 and the second snap-fit 202 are flexible and deflectable according to the forces acting on the first zipper 100 and the second zipper 200.

[0021] Additionally, the first snap-fit 102 and the second snap-fit 202 consist primarily of male structure, female structure, and complementary structure. In more detail, the first snap-fit 102 and the second snap-fit 202 comprise a total of at least two male structures 113, 213 formed in a manner that a tip has an arrow-shaped cross-section extending from the first snap-fit 102 and / or the second snap-fit 202 towards the opposite snap-fit. According to an embodiment of the present description, as shown in, the first snap-fit 102 has one male structure 113 and the second snap-fit 202 has two male structures 213.

[0022] The first snap-fit 102 and the second snap-fit 202 further comprise the female structure 114, 214, positioned at the snap-fit opposite to each of the corresponding male structure 113, 213, is characterized in having a U-shaped structure wrapping around the arrow tip of the male structure 113, 213, and the tip of the female structure 114, 214 is curved back towards the tip of the male structure 113, 213. According to an embodiment of the present description, as shown in, the first snap-fit 102 has two female structures 114, as the U-shaped structure wrapping around the arrow tip of the male structure 213 of the two second snap-fits 202. Furthermore, the tip of the female structure 114 is curved back towards the tip of the male structure 213 and attached to the arrow tip of the male structure 213. Accordingly, it can be seen that the first snap-fit 102 has one male structure 113 formed between two female structures 114, wherein each of the female structure 114 is formed from the male structure 113 on each side and one arm of the female structure 114 extending from the first base 101. Meanwhile, the second snap-fit 202 has one female structure 214 positioned between the two male structures 213 and the said female structure 214 is formed from the structure of the two male structures 213. When the female structure 214 is aligned fit with the male structure 113 of the first snap-fit 102, the arrow tip of the male structure 213 of the second snap-fit 202 is clung and attached to the arrow tip of the male structure 113 of the first snap-fit 102.

[0023] Additionally, the first snap-fit 102 and the second snap-fit 202 further comprise at least two complementary structures 215 formed at the first snap-fit 102 and / or the second snap-fit 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 snap-fit, and extending towards the opposite base. According to an embodiment of the present invention, as shown in, there are two complementary structures 215 on the side of the second snap-fit 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 snap-fit 102 and extending towards the first base 101. This complementary structure 215 is, therefore, characterized to protrude to support the arm of the female structure 114, which limits the twisting of the zipper and prevents tampering at the end of the arm of the female structure 114.

[0024] Hence, it can be seen that the confidential zipper bag according to the first embodiment of the present invention has a total of 4 attachment points between the first zipper 100 and the second zipper 200, i.e., 2 points between the tip of the female structure 114 and the arrow tip of the male structure 213 and 2 points between the arrow tip of the male structure 113 and the arrow tip of the male structure 213, making the first zipper 100 and the second zipper 200 firmly clung and attached to each other, together with having the at least two complementary structures 215, as described above, will limit the twisting of the zipper while preventing tampering through the gap between the zipper and the base of the zipper. As a result, the zipper can be effectively prevented from separating even if the zipper is twisted or tampered.

[0025] Additionally, as shown in, the first base 101 and the second base 201, at the base area 116, 216 of the first snap-fit 102 and the second snap-fit 202, respectively, are formed thicker than other areas of the first base 101 and the second base 201. In addition, on the outer surfaces of the first base 101 and the second base 201, there are two ridges 117, 217 on each side. These ridges 117, 217 will strengthen the base of the first zipper 100 and the second zipper 200 and can prevent the zipper from twisting more firmly.

[0026] Thus, the present invention can prevent the first zipper 100 and the second zipper 200 from sliding apart even if the zipper is twisted or tampered. The third party cannot access the documents or items inside the confidential zipper bag and close the zipper back without the recipient knowing that the confidential zipper bag has been opened before receiving. Thus, the user can use the confidential zipper bag to its full potential and for its intended purpose.

[0027] Next, as shown in, the bag end 3 comprises the tearable section 31, the bag end zipper assembly 32, and the ridge 33.

[0028] The tearable section 31 is characterized in being attached to the wall of the bag body 1 and positioned slightly above the bottom 4 of the bag. If the tearable section 31 is torn, a gap is created to allow access to the internal space of the bag body 1. In an embodiment of the present invention, the tearable section 31 is characterized in having two perforated lines horizontally arranged on the same plane on both sides of wall of the bag end 3 and on the position at a distance from the bottom 4 of the bag.

[0029] On the position above the tearable section 31 along the axis of the bag body 1 is the bag end zipper assembly 32 installed. This bag end zipper assembly 32 comprises a male zipper 321 attached to one inner wall of the bag end 3 and a female zipper 332 attached to the other inner wall of the bag end 3 and has a structure that conforms and is attachable to the male zipper 321. In an embodiment of the present invention, as shown in, the male zipper 321 is attached to the inner wall on the same side as the first snap-fit 102 and the female zipper 322 is attached to the inner wall on the same side as the second snap-fit 202.

[0030] The bag end 3 further comprises the ridge 33 installed on the inner and outer walls of the bag end 3 on the position between the tearable section 31 and the bag end zipper assembly 32, wherein the ridge 33 comprises two of the first ridges 331, positioned on the outer wall on the same side as the female or male zipper of the bag end zipper assembly 32. In an embodiment of the present invention, it is on the same side as the male zipper 321 of the bag end zipper 32, two of the second ridges 332 are positioned on the inner wall on the same side as the first ridge 331 on the position relative to the first ridge 331; in a manner that the second ridge 332 bears the forces acting on the first ridge 331 by the user’s fingers. A third ridge 333 is positioned on the inner wall opposite to the second ridge 332, i.e., on the same side as the female zipper 332 of the bag end zipper 32, and is positioned between the two second ridges 332. A fourth ridge 334 is positioned on the outer wall on the same side as the third ridge 333 on the position relative to the third ridge 333; in a manner that the third ridge 333 bears the forces acting on the fourth ridge 334 by the user’s fingers.

[0031] Therefore, when the user wants to access an object stored within the closed confidential zipper bag, the user will not be able to open the confidential zipper bag by detaching the first zipper 100 and the second zipper 200 at the opening of the bag. However, the user can open the bag by tearing the bag at the tearable section 31 until the opening is formed; using fingers to grasp and squeeze the first ridge 331 and the fourth ridge 334 together; the second ridge 332 and the third ridge 333 will bear the force of the user's hand and move towards each other until the third ridge 333 is aligned within the gap between the two second ridges 332. Then the user exerts torque, moves the first ridge 331 and the fourth ridge 334 in opposite directions, i.e., push the first ridge 331 downward along the axis of the bag body 1 and push the fourth ridge 334 upward along the axis of the bag body 1 (in the opening 2 direction), or push the first ridge 331 upward along the axis of the bag body 1 and push the fourth ridge 334 downward along the axis of the bag body 1. The application of this sliding torque creates conflicting force between the second ridge 332 and the corresponding third ridge 333. This conflicting force is transmitted through the wall of the bag body 1 to the bag end zipper assembly 32 and pushes the male zipper 321 and the female zipper 322 to detach, and the user can finally reach the object stored therein.

[0032] The bag end 3 according to the present invention allows the user to open the closed zipper bag quickly and without the need for additional equipment. Additionally, if the tearable section 31 has already been torn before the zipper bag reaches the recipient, it serves as a means of warning that the stored object may have been accessed before it reaches the recipient.

[0033] Next, as shown in, the opening 2 further comprises an anti-locking structure 4 that can be separated from the zipper bag and can be sandwiched between the first zipper 100 and the second zipper 200, as shown in, wherein the anti-locking 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 elongating along the entire length of the first zipper 100 or the second zipper 200. The anti-locking structure 4 and the wall of the bag body are connected by a perforation 401 elongating in a straight line across the width of the zipper bag. In an embodiment of the present invention, the anti-locking structure 4 is a flap extending from the wall of the bag body 1 above the first zipper 100 and elongating along the entire length of the first zipper 100, wherein the anti-locking structure 4 and the wall of the bag body are connected by the perforation 401 elongating in a straight line across the width of the zipper bag.

[0034] Thus, the user can fold the anti-locking structure 4 towards the inside of the opening 2 so that the anti-locking structure 4 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 and attached to each other. When the user loads the object into the bag body 1 and squeezes the first zipper 100 and the second zipper 200 to attach and fix them together, then the user can tear off the anti-locking structure 4 from the bag body 1 along the perforation 401.

[0035] Additionally, in another embodiment of the present invention, as shown in, the first snap-fit 102 consists of two male structures 113 and one female structure 114 as the U-shaped structure formed by the two male structures 113 and then positioned between both two male structures 113. The second snap-fit 202 has two female structures 214 having the U-shaped structure wrapping around the arrow tip of the male structure 113 of the two first snap-fit 102. The tip of the female structure 214 is curved back towards the tip of the male structure 113 and clung and attached to the arrow tip of the male structure 113. As it can be seen that the second snap-fit 202 has one male structure 213 formed between two female structures 214, wherein each of the female structure 214 is formed from the male structure 213 on each side and one arm of the female structure 214 extends from the second base 201. Additionally, the first snap-fit 102 further comprises two complementary structures 115 formed at the position between the first base 101 and the tip of the female structure 214 of the second snap-fit 202 and extends towards the tip of the female structure 214. This complementary structure 115 is therefore similar to squeezing the arm of the female structure 214 and keeping it attached to the end of the male structure 113, which will further limit twisting and prevent tampering at the end of the arm of the female structure 214. Additionally, the first base 101 and the second base 201 at the base area 116, 216 of the first snap-fit 102 and the second snap-fit 202, respectively, are formed thicker than other areas of the first base 101 and the second base 201. Also, 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 will strengthen the base of the first zipper 100 and the second zipper 200, and can prevent the zipper twisting more firmly.

[0036] In another embodiment of the present invention, as shown in, the first snap-fit 102 consists of one male structure 113 and one female structure 114 formed from one side of the male structure 113 and the arm of the female structure and having the U-shaped structure wrapping around the arrow tip of the male structure 213 of the second snap-fit 202. The tip of the female structure 114 is curved back towards the tip of the male structure 213 and similarly attached to the arrow tip of the male structure 213. The second snap-fit 202 consists of one male structure 213 and one female structure 214 formed from one side of the male structure 213 and the arm of the female structure and having the U-shaped structure wrapping around the arrow tip of the male structure 113 of the first snap-fit 102. The tip of the female structure 214 is curved back towards the tip of the male structure 113 and attached to the arrow tip of the male structure 113.

[0037] Additionally, the first snap-fit 102 further comprises the first complementary structure 115 and the second complementary structure 118. The first complementary structure 115 is embossed from the first base 101 extending into the tip of the female structure 214 of the second snap-fit 202. The second complementary structure 118 is formed to extend from the base 116 of the first snap-fit 102 on the position between the first complementary structure 115 and the arm of the female structure 214 of the second snap-fit 202, and elongate to encircle the arm of the female structure 214. Similarly, the second snap-fit 202 further comprises the first complementary structure 215 and the second complementary structure 218. The first complementary structure 215 is embossed from the second base 201 extending into the tip of the female structure 114 of the first snap-fit 102 and the second complementary structure 218 is formed to extend from the base 216 of the second snap-fit 202 on the position between the first complementary structure 215 and the arm of the female structure 114 of the first snap-fit 102 and elongate to encircle the arm of the female structure 114. Thus, the first complementary structure 115, 215, and the second complementary structure 118, 218 will limit the twisting of the zipper and control the attachment between the male structure and the female structure more securely. Additionally, 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 will add thickness to the base of the first zipper 100 and the second zipper 200, and can prevent the zipper from twisting more firmly.

[0038] In addition to the various embodiments described in detail herein, modifications may be clearly understood and can be made by those skilled in the art of the confidential zipper bag, to obtain the confidential zipper bag that can prevent the male zipper and the female zipper from sliding apart even if the zipper is twisted or tampered, within the scope and spirit of the invention as appeared in the appended claims.
