Description

Technical Field

[0001] This utility model relates to the field of engineering, and in particular to a confidential zipper bag. Background Technology

[0002] Generally, discreet zipper bags are designed to be impossible to open by conventional methods—that is, the zipper cannot be separated by pulling or twisting the bag's opening. This ensures the confidentiality of the documents or items stored inside until the bag is delivered to the recipient to whom the sender intends to disclose them. Therefore, mechanisms exist to prevent access to the internal space of the zipper bag in various ways, including mechanisms that help the recipient detect if the discreet zipper bag has been opened before delivery (e.g., the zipper is not separated when the opening is pulled, but the bag is torn).

[0003] However, as Figure 1 As shown, current confidential zippered bags (such as Thai patent application number 1301007211) have small zipper bases and small attachment points between the convex and concave zippers. Therefore, users have discovered a problem: even if the convex and concave zippers cannot be separated by applying a force in a straight direction (e.g., by pulling them apart), they may still slide apart if the zipper is twisted or damaged. Thus, a third party can access the documents or items stored inside and then close the confidential zippered bag as before, without the recipient knowing the bag had been opened before receiving it, thus failing to fully utilize the confidential zippered bag and achieve its intended purpose. Utility Model Content

[0004] Therefore, this utility model aims to overcome the above-mentioned problems by providing a discreet zipper bag. According to one aspect, a discreet zipper bag includes: a bag body having an internal space formed by two walls; an opening installed at the top of the bag body, wherein an article can enter the bag body through the opening for storage in the bag body; a bag end located at the bottom of the bag body, and the bag end being a closed end; a first zipper including a first base attached to a first inner wall of the opening and a first engaging portion attached to the first base; and a second zipper including a second base attached to a second inner wall of the opening and a second engaging portion attached to the second base, wherein the second engaging portion has a structure that matches and can be attached to the first engaging portion, wherein the first engaging portion and the second engaging portion are flexible. The first and second zippers are designed to deflect according to the forces acting on them, wherein the first and second engaging portions include: at least two convex structures formed such that their tips have arrow-shaped cross-sections extending from the first and / or second engaging portions toward the opposing engaging portions; concave structures located at the engaging portions opposite to each corresponding convex structure, the concave structures having U-shaped structures that enclose the arrow-shaped tips of the convex structures, wherein the tips of the concave structures bend back toward the tips of the convex structures; and at least two supplementary structures formed at the first and / or second engaging portions, located between the first and / or second bases and the tips of the concave structures of the opposing engaging portions, and extending toward the opposing bases.

[0005] In one embodiment, the first engaging portion has a first convex structure formed between two first concave structures, wherein each first concave structure is formed by a first convex structure on each side and an arm of the first concave structure extending from the first base, and wherein the second engaging portion has two second convex structures, a second concave structure, and two third supplementary structures, wherein the second concave structure is formed by the two second convex structures and is located between the two second convex structures, and the third supplementary structures extend from the second base to a position between the ends of the arms of the two first concave structures of the first engaging portion and extend toward the first base.

[0006] In one embodiment, the first base and the second base are formed to be thicker than other regions of the first base and the second base, respectively, in the first base region and the second base region of the first engaging portion and the second engaging portion.

[0007] In one embodiment, the first base and the second base are respectively located in the first base region and the second base region of the first engaging portion and the second engaging portion, and each side has a first outer ridge and a second outer ridge, which protrude from the outer surface of the first base and the second base.

[0008] In one embodiment, the bag end includes a tearable portion that, when opened, allows access to the interior space of the bag. The tearable portion has two perforated lines arranged horizontally on the same plane on both sides of the wall of the bag end, and the two perforated lines are located at a certain distance from the bottom of the bag.

[0009] In one embodiment, the bag end also includes a bag end zipper assembly mounted above the tearable portion along the axial direction of the bag body, wherein the bag end zipper assembly includes a convex zipper attached to one inner wall of the bag end and a concave zipper attached to another inner wall of the bag end, the concave zipper having a structure that matches and can be attached to the convex zipper.

[0010] In one embodiment, the bag end also includes a spine, which is mounted on the inner and outer walls of the bag end and located between the tearable portion and the bag end zipper assembly. The spine includes: two first spines located on the outer wall on the same side as the concave or convex zipper of the bag end zipper assembly; two second spines located on the inner wall on the same side as the first spines and positioned relative to the first spines such that the second spines bear the force exerted on the first spines by the user's fingers; a third spine located on the inner wall opposite to the second spines and between the second spines; and a fourth spine located on the outer wall on the same side as the third spines and positioned relative to the third spines such that the third spine bears the force exerted on the fourth spines by the user's fingers.

[0011] In one embodiment, the opening also includes an anti-locking structure that can be separated from the zippered pocket and clamped between the first zipper and the second zipper.

[0012] In one embodiment, the anti-locking structure is a flap extending from the wall of the bag body above the first or second zipper and along the entire length of the first or second zipper. The anti-locking structure is connected to the wall of the bag body by a perforated line extending in a straight line across the width of the zippered bag. Therefore, the security zippered bag according to this invention includes at least three attachment points between the two engaging portions, thereby providing a reliable attachment between the zippers. This invention also provides supplementary structures, thus more effectively preventing tampering and damage, while more effectively limiting torsion by third parties.

[0013] Furthermore, according to another aspect, the first base and second base of the first and second engaging portions are respectively formed to be thicker than other areas of the first and second bases. This makes the convex and concave zippers more difficult to twist and separate.

[0014] Therefore, this invention prevents the convex and concave zippers from sliding apart when the zipper is twisted or tampered with. Third parties cannot access documents or items stored inside the confidential zippered bag and cannot zip it up again without the recipient knowing the bag was opened before receipt. Thus, users can fully utilize the confidential zippered bag and use it for its intended purpose. Attached Figure Description

[0025] Embodiments of this utility model will be described in detail with reference to the accompanying drawings.

[0026] In this utility model Figure 2 In the illustrated embodiment, the discreet zippered bag includes a bag body 1 having an internal space formed by two walls. An opening 2 is provided at the top of the bag body 1, through which an item can enter the bag body for storage, and a bag end 3 is a closed end at the bottom of the bag body 1.

[0027] like Figure 3 As shown, a first zipper 100 and a second zipper 200 are provided at the opening 2, extending parallel to the opening 2 across the zippered pocket. The first zipper 100 consists of a first base 101 and a first engaging portion 102. The first base 101 is attached to a first inner wall of the opening 2, and the first engaging portion 102 is attached to the first base 101. Similarly, the second zipper 200 consists of a second base 201 attached to a second inner wall of the opening and a second engaging portion 202 attached to the second base 201. The second engaging portion 202 has a structure that matches and can be attached to the first engaging portion 102. When the first engaging portion and the second engaging portion are attached together, entry into the interior space of the zippered pocket is prevented. When the first engaging portion and the second engaging portion are separated, entry into the interior space of the zippered pocket is allowed. Furthermore, the first engaging portion 102 and the second engaging portion 202 are flexible and can deflect according to the force acting on the first zipper 100 and the second zipper 200.

[0028] Furthermore, the first engaging portion 102 and the second engaging portion 202 are mainly composed of convex structures, concave structures, and supplementary structures. More specifically, the first engaging portion 102 and the second engaging portion 202 include a total of at least two convex structures, which are formed such that their tips have arrow-shaped cross-sections extending from the first engaging portion 102 and / or the second engaging portion 202 toward the opposing engaging portion. According to embodiments of this specification, such as... Figure 4 As shown, the first engaging portion 102 has a first convex structure 113, and the second engaging portion 202 has two second convex structures 213.

[0029] The first engaging portion 102 and the second engaging portion 202 also include concave structures located at engaging portions opposite each corresponding convex structure. These concave structures are characterized by having a U-shaped structure that wraps around the arrowhead-shaped tip of the convex structure, and the tip of the concave structure bends back toward the tip of the convex structure. According to embodiments of this specification, such as... Figure 4As shown, the first engaging portion 102 has two first concave structures 114, which are U-shaped structures that wrap around the arrow-shaped tips of the two second convex structures 213 of the second engaging portion 202. Furthermore, the tips of the first concave structures 114 bend back towards the tips of the second convex structures 213 and attach to the arrow-shaped tips of the second convex structures 213. Therefore, it can be seen that the first engaging portion 102 has a first convex structure 113 formed between the two first concave structures 114, wherein each first concave structure 114 is formed by the first convex structure 113 on each side and an arm of the first concave structure 114 extending from the first base 101. Simultaneously, the second engaging portion 202 has a second concave structure 214 located between the two second convex structures 213, the second concave structure 214 being formed by the structure of the two second convex structures 213. When the second concave structure 214 is aligned and engaged with the first convex structure 113 of the first engaging portion 102, the arrow-shaped tip of the second convex structure 213 of the second engaging portion 202 is closely attached to and attached to the arrow-shaped tip of the first convex structure 113 of the first engaging portion 102.

[0030] Furthermore, the first engaging portion 102 and the second engaging portion 202 also include at least two third supplementary structures 215. These two supplementary structures are formed at the first engaging portion 102 and / or the second engaging portion 202, located between the first base 101 and / or the second base 201 and the slightly concave structure of the opposite engaging portion, and extend toward the opposite base. According to an embodiment of the present invention, such as Figure 4 As shown, there are two third supplementary structures 215 on the side of the second engaging portion 202. These two supplementary structures extend from a position between the ends of the arms of the two first concave structures 114 of the second base 201 and the first engaging portion 102, and extend toward the first base 101. Therefore, the third supplementary structures 215 are characterized by protruding to support the arms of the first concave structures 114, which limits the twisting of the zipper and prevents the ends of the arms of the first concave structures 114 from being damaged.

[0031] Therefore, it can be seen that the confidential zipper bag according to the first embodiment of this utility model has a total of four attachment points between the first zipper 100 and the second zipper 200, namely, two points between the tip of the first concave structure 114 and the arrow-shaped tip of the second convex structure 213, and two points between the arrow-shaped tips of the first convex structure 113 and the second convex structure 213. This ensures that the first zipper 100 and the second zipper 200 are firmly attached to each other. Combined with the at least two third supplementary structures 215 as described above, it can both limit the twisting of the zipper and prevent damage through the gap between the zipper and the base of the zipper. Therefore, even if the zipper is twisted or damaged, it can effectively prevent the zipper from separating.

[0032] In addition, such as Figure 5 As shown, the first base 101 and the second base 201 are respectively formed at the first base region 116 and the second base region 216 of the first engaging portion 102 and the second engaging portion 202, which are thicker than other regions of the first base 101 and the second base 201. Furthermore, on the outer surfaces of the first base 101 and the second base 201, there are first outer ridges 117 and second outer ridges 217 on each side. These outer ridges reinforce the bases of the first zipper 100 and the second zipper 200 and can more firmly prevent zipper twisting.

[0033] Therefore, this invention can prevent the first zipper 100 and the second zipper 200 from sliding apart even if the zipper is twisted or damaged. Third parties cannot access the documents or items inside the confidential zippered bag and cannot zip it up again without the recipient knowing that the bag was opened before receipt. Therefore, users can fully utilize the confidential zippered bag and use it for its intended purpose.

[0034] Next, as Figure 6 As shown, the bag end 3 includes a tearable portion 31, a bag end zipper assembly 32, and a spine 33.

[0035] The tearable portion 31 is characterized by being attached to the wall of the bag body 1 and located slightly above the bottom 4 of the bag. When the tearable portion 31 is torn open, a gap is formed, thereby allowing access to the interior space of the bag body 1. In an embodiment of the present invention, the tearable portion 31 is characterized by having two perforated lines, which are arranged horizontally on the same plane on both sides of the wall of the bag end 3 and located at a certain distance from the bottom 4 of the bag.

[0036] Along the axial direction of the bag body 1, a bag end zipper assembly 32 is installed above the tearable portion 31. This bag end zipper assembly 32 includes a convex zipper 321 attached to one inner wall of the bag end 3 and a concave zipper 332 attached to the other inner wall of the bag end 3, and the bag end zipper assembly has a structure that matches and can be attached to the convex zipper 321. In embodiments of this utility model, such as... Figure 6 As shown, the convex zipper 321 is attached to the inner wall on the same side as the first engaging portion 102, and the concave zipper 322 is attached to the inner wall on the same side as the second engaging portion 202.

[0037] The bag end 3 also includes a ridge 33, which is mounted on the inner and outer walls of the bag end 3, located between the tearable portion 31 and the bag end zipper assembly 32. The ridge 33 includes two first ridges 331, located on the outer wall of the bag end zipper assembly 32 on the same side as the concave or convex zipper. In an embodiment of the present invention, on the same side as the convex zipper 321 of the bag end zipper assembly 32, two second ridges 332 are located on the inner wall on the same side as the first ridges 331 and are arranged opposite to the first ridges 331; this arrangement allows the second ridges 332 to withstand the force exerted by the user's fingers on the first ridges 331. A third ridge 333 is located on the inner wall opposite to the second ridges 332 (i.e., on the same side as the concave zipper 322 of the bag end zipper assembly 32) and is located between the two second ridges 332. The fourth ridge 334 is located on the outer wall on the same side as the third ridge 333 and is positioned opposite to the third ridge 333; this arrangement allows the third ridge 333 to bear the force exerted by the user's fingers on the fourth ridge 334.

[0038] Therefore, when a user wants to access items stored in the closed, discreet zippered bag, the user cannot open the bag by unzipping the first zipper 100 and the second zipper 200 at the bag opening. However, the user can open the bag by: tearing the bag at the tearable portion 31 until an opening is formed; simultaneously grasping and squeezing the first ridge 331 and the fourth ridge 334 with their fingers; the second ridge 332 and the third ridge 333 will bear the force of the user's hand and move toward each other until the third ridge 333 aligns with the gap between the two second ridges 332. Then, the user applies torque to move the first ridge 331 and the fourth ridge 334 in opposite directions, that is, pushing the first ridge 331 downward along the axis of the bag body 1 and pushing the fourth ridge 334 upward along the axis of the bag body 1 (towards the opening 2), or pushing the first ridge 331 upward along the axis of the bag body 1 and pushing the fourth ridge 334 downward along the axis of the bag body 1. The application of the sliding torque generates a 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 zipper assembly 32 at the end of the bag and pushes the convex zipper 321 and the concave zipper 322 apart, so that the user can finally reach the items stored inside.

[0039] The bag end 3 according to this invention allows the user to quickly open the closed zippered bag without the need for additional devices. Furthermore, if the tear-away portion 31 has been torn open before the zippered bag is delivered to the recipient, it can serve as a warning that the stored items may have been approached before delivery.

[0040] Next, as Figure 7AAs shown, the opening 2 also includes an anti-locking structure 5 that can be separated from the zippered pocket and is sandwiched between the first zipper 100 and the second zipper 200, such as... Figure 7B As shown, the anti-locking structure 5 is a flap extending from the wall of the bag body 1 above the first zipper 100 or the second zipper 200 and along the entire length of the first zipper 100 or the second zipper 200. The anti-locking structure 5 is connected to the wall of the bag body by a perforated line 401 extending in a straight line across the width direction of the zipper bag. In an embodiment of the present invention, the anti-locking structure 5 is a flap extending from the wall of the bag body 1 above the first zipper 100 and along the entire length of the first zipper 100, wherein the anti-locking structure 5 is connected to the wall of the bag body by a perforated line 401 extending in a straight line across the width direction of the zipper bag.

[0041] Therefore, the user can fold the anti-locking structure 5 inwards towards the opening 2 so that the anti-locking structure 5 is located between the first zipper 100 and the second zipper 200. This is to prevent the first zipper 100 and the second zipper 200 from accidentally inserting into and attaching to each other. When the user puts items into the bag body 1 and squeezes the first zipper 100 and the second zipper 200 to attach and secure them together, the user can then tear the anti-locking structure 5 off the bag body 1 along the perforation line 401.

[0042] Furthermore, in another embodiment of this utility model, such as Figure 8As shown, the first engaging portion 102 consists of two first convex structures 113 and one first concave structure 114. The first concave structure is a U-shaped structure formed by the two first convex structures 113 and located between the two first convex structures 113. The second engaging portion 202 has two second concave structures 214, each having a U-shaped structure that wraps around the arrow-shaped tips of the first convex structures 113 of the two first engaging portions 102. The tips of the second concave structures 214 bend back toward the tips of the first convex structures 113 and are tightly attached to and abut against the arrow-shaped tips of the first convex structures 113. It can be seen that the second engaging portion 202 has a second convex structure 213 formed between the two second concave structures 214, wherein each second concave structure 214 is formed by the second convex structure 213 on each side and an arm of the second concave structure 214 extending from the second base 201. Furthermore, the first engaging portion 102 also includes two first supplementary structures 115, which are formed between the first base 101 and the tip of the second concave structure 214 of the second engaging portion 202, and extend toward the tip of the second concave structure 214. Therefore, the first supplementary structure 115 acts as a compression arm of the second concave structure 214 and holds it attached to the end of the first convex structure 113, which further restricts twisting and prevents damage to the end of the arm of the second concave structure 214. Additionally, the first base 101 and the second base 201 are respectively formed at the first base region 116 and the second base region 216 of the first engaging portion 102 and the second engaging portion 202 to be thicker than other regions of the first base 101 and the second base 201. Furthermore, the outer surfaces of the first base 101 and the second base 201 each have a first outer ridge 117 and a second outer ridge 217 on each side. These ridges will reinforce the base of the first zipper 100 and the second zipper 200, and can more firmly prevent the zippers from twisting.

[0043] In another embodiment of this utility model, such as Figure 9As shown, the first engaging portion 102 consists of a first convex structure 113 and a first concave structure 114. The first concave structure is formed by a side portion of the first convex structure 113 and an arm of the first concave structure, and has a U-shaped structure that surrounds the arrow-shaped tip of the second convex structure 213 of the second engaging portion 202. The tip of the first concave structure 114 bends back toward the tip of the second convex structure 213 and is similarly attached to the arrow-shaped tip of the second convex structure 213. The second engaging portion 202 consists of a second convex structure 213 and a second concave structure 214. The second concave structure is formed by a side portion of the second convex structure 213 and an arm of the concave structure, and has a U-shaped structure that surrounds the arrow-shaped tip of the first convex structure 113 of the first engaging portion 102. The tip of the second concave structure 214 bends back toward the tip of the first convex structure 113 and is attached to the arrow-shaped tip of the first convex structure 113.

[0044] Furthermore, the first engaging portion 102 also includes a first supplementary structure 115 and a second supplementary structure 118. The first supplementary structure 115 protrudes from the first base 101 and extends to the tip of the second concave structure 214 of the second engaging portion 202. The second supplementary structure 118 is formed to extend from the first base region 116 of the first engaging portion 102 at a position between the first supplementary structure 115 and the arm of the second concave structure 214 of the second engaging portion 202, and extends to surround the arm of the second concave structure 214. Similarly, the second engaging portion 202 also includes a third supplementary structure 215 and a fourth supplementary structure 218. A third supplementary structure 215 protrudes from the second base 201 and extends to the tip of the first concave structure 114 of the first engaging portion 102. A fourth supplementary structure 218 is formed to extend from the second base region 216 of the second engaging portion 202 at a position between the third supplementary structure 215 and the arm of the first concave structure 114 of the first engaging portion 102, and extends to surround the arm of the first concave structure 114. Therefore, the first supplementary structure 115, the second supplementary structure 118, the third supplementary structure 215, and the fourth supplementary structure 218 will limit the twisting of the zipper and more firmly control the attachment between the convex and concave structures. In addition, the outer surfaces of the first base 101 and the second base 201 have a first outer ridge 117 and a second outer ridge 217 on each side. These ridges will increase the thickness of the base of the first zipper 100 and the second zipper 200 and can more firmly prevent the zipper from twisting.

[0045] In addition to the various embodiments described in detail herein, those skilled in the art of discreet zipper bags will clearly understand and make modifications within the scope and spirit of the appended claims to obtain discreet zipper bags that prevent the convex and concave zippers from sliding apart even if the zipper is twisted or damaged.
