Definitions

  • the present disclosure relates to sealing of a carton box used for packaging. More particularly, disclosure is related to the tamper evident sealing of a packaging box, a process for sealing of boxes, and box sealing machine / apparatus.
  • the disclosure relates to the field of sealing of corrugated cartons.
  • These corrugated cartons also known as shipper boxes or Cases.
  • the word “carton”, shipper boxes or Cases etc used for packaging of articles in the packaging industries shall be referred as "Box”.
  • the box may be in any shape like rectangular, square or cuboid etc.
  • the present subject matter relates to sealing of these boxes in such a manner so that it can easily establish if sealed box has been tampered.
  • Boxes are used for packaging of articles, portability and transportation purposes. Use of boxes in the Industry is so important that almost each and every item need to be packed in a box for many reasons. Some of the reasons are intactness of the items inside box, stackabality, low cost, ease of transportation, flexibility of size and shape of boxes etc.
  • Boxes are sealed to prevent falling of articles contained there within and falling of the articles outside the packaged box when the packaged boxes are in transit. Further, reason is to avoid pilferage.
  • One of the most common criteria for sealing of box is use of Self- Adhesive Tapes, or BOPP tapes also referred as biaxially oriented polypropylene tapes.
  • these sealing tapes can be removed or tampered to open the packed boxes so that the product(s) inside the packed boxes can be taken out (Pilferage).
  • the tapes can be put back easily and without too much cost. The pilferage or the tampering of the box will not be evident to the receiver of the box.
  • Self-adhesive tapes are used at the flaps of box to close and seal the box. But the vulnerability issue of removal of articles from the tape sealed box is very high as it is very easy to de-seal the boxes, remove the articles from the boxes and re-seal the boxes.
  • the sealed and packed boxes when delivered to the end person (Receiver), it is difficult for a receiver to ascertain if the sealed and packed containers have been opened during the transit and inside articles have been stolen or replaced with the low quality product or with the duplicate or with the fake articles. This is because self-adhesive tapes can be easily removed / tampered by strangers to tamper the sealed boxes and re-taped so that there is no tampering evidence left on the packed and sealed boxes.
  • HMA Hot Melt Adhesives
  • WBA Water Based Adhesive
  • the other sealing process of boxes is using Water Based Adhesive hereinafter referred as WBA, which is cheaper than hot melts.
  • WBA Water Based Adhesive
  • the sealing of box using WBA provides a better tamper evident sealing system compared to hot melts and BOPP tapes.
  • WBA provides best fiber tear as the adhesive enters and travels through the fibrous pores of paper, unlike hot melt or tapes.WBA is less costly compared to the HMA sealing and sealing with the BOPP/ self-adhesive tape.
  • WBA also joins all the flaps of the box together, increasing the surface area to sustain the load and provides structural integrity to the box thereby protecting the products inside, better than tapes. But, the WBA takes time to become dry for making bonding between flaps to seal the box making it difficult to employ in productive environments.

  • the disclosure is novel in respect of applying of water based adhesive through nozzle applicator to improve the productivity.
  • nozzle applicator are used to apply cold adhesive / water based adhesive on to flaps of boxes in a controlled manner and then immediately after this the boxes are either sealed using self-adhesive tapes or transported in the production line under pressure for some time till the water based adhesive is dried.
  • the patent is applied for this processes that help in sealing of boxes using water based adhesive that provide better tamper evidence at the same time achieve the required productivity / speed.
  • the invention involves using a suitable adhesive system to apply high viscosity/ high solids content water based adhesive (emulsion) to seal the box.
  • the main object of the present disclosure is to provide sealed boxes which are tamperproof in relation of tamper evident.
  • the object of the present disclosure is to provide evidence of tampering, if sealed box is tampered.
  • the object of the present disclosure is to easily detect the tampering and judge the tampering of box quickly at the time of receiving.
  • the object of the present disclosure is to find the tampering of the box without specific tools or system.
  • the another object of the present disclosure is to provide a box sealing system that seals boxes such that any tampering with the seal is easily identified.

  • Figure 10 is a boxes supplied by the manufacturer for packaging and sealing the packed product.
  • the hot melt adhesive is basically chemical material which is in solid form at normal temperature and pressure (NTP).
  • the HMA material may be in powder, granular or in stick form and can be selected as per application of articles to be sealed.
  • the drawback of this technique is that the hot melts provide only surface bonding between the two flaps and by applying heat again (which is the carrier), we can detach the flaps / de-bond. Exposed to extreme heat conditions or freezing conditions the de-lamination or de-bonding can take place. So HMA sealed box do not tear the flaps or tear the fibre, if tampering made with the sealed box. Accordingly, uses of HMA alone do not leave any evidence of tampering of sealed box. This is the major disadvantage. Hot melts also leave a gap between the two flaps that can allow dust to enter.
  • the one way of sealing of the boxes comprises applying of different types of adhesives on the receiving flaps of the box during the process of sealing in the box sealing machine.
  • One of the commonly used adhesive is a HMA in the box sealing machine.
  • WBA water based adhesive
  • cold glue/ adhesive In another conventional manner of sealing of the box is use of water based adhesive (WBA) or cold glue/ adhesive.
  • WBA is cheaper than hot melts and also provide better bonding, and has resistance to extreme heat and cold. But sealing through it takes time to form, a strong bond. Contrary to HMA which remains on the surface and do not penetrate through pores of the box fiber, WBA being in water solvent penetrates through the pores of paper surface and after drying provides a bonding that is tamper evident. Any attempt to tamper or de-bond the sealing tears the flap bonded paper/fiber which as such can't be rebounded thus providing tamper evidence.
  • WBA sealing is cheap, more tamper evident features but drawback is that it requires time for drying of WBA.
  • WBA have not been used in mechanized process lines or in box sealing machine or in process of sealing through the machine. That is what is the innovation is doing it by combining with a process that will give time for drying - plus give additional tamper evidence.
  • the present disclosure provides the solution related to the problem associate with drying time of WBA, which gives slow productivity and costly sealing process using separate devices to keep flap intact till WBA dries completely on the flap and make sealing bond strongly.
  • This disclosure in accordance with a present invention is providing an additional bonding of either hot melts or BOPP tapes used in conjunction with the water based adhesive / cold adhesive.
  • This multiple sealing process provides tamper evidence which is not available in any other process, while keeping this much cheaper than processes like water activated tapes.
  • the box is sealed through multiple sealing - where WBA and tapes are used.
  • WAT water activated tape
  • one solution is providing an additional bonding of either hot melts or BOPP tapes used in conjunction with the water based adhesive / cold adhesive.
  • This multiple sealing process provides tamper evidence which is not available in any other process, while keeping this much cheaper than processes like water activated tapes.
  • each box (100) has a plurality of flaps for enclosing at least one of the operative bottoms, the operative top, one or more of operative side(s).
  • each operative bottom and operative top have four flaps of which a first pair denoted and referred by receiving flaps of oppositely disposed flaps is closed first, and then the transversely disposed second pair is denoted and referred by closing flaps, of oppositely disposed flaps are positioned on the receiving flaps to form a seal of flaps there between.

  • a Pressing / Over-sealing mechanism is required for water based adhesive sealing of the boxes.
  • the water-based adhesive sealing of boxes takes enough time for drying of WBA. Till WBA dries completely, receiving flap and closing flap keep intact.
