Definitions

  • the present invention relates to a tampering-evident bag and said bag comprising closures.
  • Plastic bags with zippers have been widely accepted in various business segments, such as the pharmaceuticals industry, food industry and logistics or shipping industry.
  • the zipper bags have long been used in packaging, delivering of products/services for convenience, health hygiene and security reasons. In most applications, however, these zipper bags can be repeatedly sealed, unsealed and resealed. For certain products and services, this could pose a high risk to consumers or customers, as the bags could have easily been tampered with, or exposed to theft, or sent to unauthorized or unintended recipients. Therefore, it is generally considered prudent to provide zipper bags with tampering- evident features, in order to avoid unauthorized access, or to alert recipients of such unauthorized access or theft.
  • U.S. Patent Publication No. 2004/0078940 disclosed a plastic bag, which is made by fusing film material so as to have an upper opening portion.
  • a zipper is provided on the inner surface of the opening portion, and the zipper has a groove formed on a base tape and a ridge formed on another base tape; the groove and the ridge are capable of engaging and disengaging from each other.
  • the base tapes are of different colors.
  • the base tapes have parts which serve as flaps, and the flap parts are of different widths. Thereby, the opening portion of the plastic bag has a step.
  • U.S. Patent No. 5, 955, 160 disclosed a snap zipper, which has a snap/zipper male member and a snap/zipper female member, characterized by including a base for fusing each snap/zipper of the male member and the female member. A male engaging portion and a female engaging portion respectively engage with each other.
  • European Patent No. 0 972 715 disclosed a method, apparatus and a system in which re-closable bags and components thereof are formed.
  • the method includes steps including supplying a continuous strip of tape, which has the first and second closures element sealed thereon.
  • the first and second closure elements have a pair of male profiles and a pair of female profiles, or U-shaped elements thereon, each shaped for interlocking with the other.
  • a thickened sealing bridge between the male elements, and a second thickened sealing bridge between the female elements allows for precise sealing of the fastener element to fastener tape, or to the bag wall, as desired. It also facilitates with keeping the profiles interlocked.
  • U.S. Patent No. 5851,071 disclosed a plastic bag which allows for bottom loading of the plastic bag, and subsequent sealing of the bottom edges of the plastic bag without the use of tools, adhesive or tape.
  • the plastic bag includes a one-time plastic zipper mechanism which is disposed at the bottom edges and which provide a one-time, permanent seal to the bottom edges of the bag. The seal is such, that it cannot be unsealed without causing discernable damage to the bag.
  • the present invention relates to a tampering-evident bag with closures as a means for safe-guarding confidential information/documents/articles, so that such confidential materials are only accessible to the intended recipient, and providing an apparent warning sign, if the bag has been tampered with.
  • the tampering-evident bag according to the principle of the present invention comprising an opening portion, and a body portion defining a pocket for holding/storing items.
  • the opening portion is provided with a first closure, which is a "deadlock" closure comprising a first profile and a second profile.
  • a "deadlock" closure comprising a first profile and a second profile.
  • the bag comprising an opening portion, a body portion and a bottom portion.
  • the bottom portion of the bag is provided with a second closure to provide easy access to the contents of the bag.
  • the second closure comprising a male and a female locking elements which may be engaged, disengaged and re-engaged as desired.
  • the second closure is positioned between a tear away section and a body portion. The contents of the bag may be accessed via the second closure at the bottom of the bag, by simply tearing away the tear away section and then unsealing the bag by disengaging the locking element of the second closure. Again, should the contents has been accessed by an unintended recipient, the absence of the tear away section will alert the intended recipient.
  • the invention provides a closure strip comprising interlocking first profile and second profile. Both the first profile and the second profile comprising a locking element, wherein interlocking of the said locking elements of the first and second profiles will form a deadlock engagement of the said profiles.

Instead, the first profile 40 and the second profile 45 are connected to a web 41 , which is located on each respective wall 50, 50" at which each of the web 41, 41" is integrally formed or attached thereto.
  • the objective of this arrangement is as follows: since the first profile 40 and the second profile 45 of the first closure 35 are not permanently fused to any of either wall 50, 50 (while loosely, but securely connected to the web 41), it will be even harder for a person to manipulate the first closure in the hope of disengaging it and opening the bag, because the first closure 35 is able to move up or down within the range of movement of the web 41.
  • the base strip 55, 55" of the first profile and the second profile 40, 45 may be prepared so as to be substantially the same size as the width of the first profile and the second profile 45.
  • the said base strip 55, 55" may be prepared with an extended length, as shown in Fig. 17.
  • the base strip 55, 55" of both the first profile and the second profile 40, 45 continue to extend in the same direction beyond the width of the first profile and the second profile 40, 45.
  • the base strip 55, 55" is adapted to transform and serve the same function as with the web 41, 41", as earlier shown and described.
  • the first profile and the second profile 40, 45 may be fused to the walls 50, 50" at the opening portion 25 of the bag 20, via the extended length of the base strip 55, 55" without the need for the web 41, 41", or fuse the entire extended length of the base strip 55, 55" to the entire length of the web 41 , 41".
  • the base strip 55, 55" and the web 41, 41 is reduced into one single element.
  • first profile 40 and the second profile 45 both engage with each other at three different positions (i.e. between 70" and 85, 80 and 80" and between 70 and 85”).
  • Such engagement provide a "deadlock" closure, or a more permanent seal, to the bag 20 due to the counter balance resistance created between the first profile 40 and the second profile 45.
  • the counter balance resistance will always exist.
  • accessing the contents of the bag 20 requires substantial force, and this will consequently result in damaging the bag 20.
  • the wall 50, 50" of the bag 20 is made relatively thin.
