Definitions

  • the present invention relates to improvements in the packaging and transportation of machine-readable discs. More specifically the present invention relates to improvements in packaging for containing, protecting and transporting DVDs and CDs, primarily for but not limited to transportation by the postal or mailing industry and to a method of manufacturing such a product.
  • One way of obtaining films, games or CDs is to obtain a rental copy of one or more of the discs containing said film, game or music by way of ordering the selected DVD, game or CD over the Internet.
  • the selected disc is then sent to the end user by a rental outlet using the postal service.
  • the end user has finished with the DVD, game or CD, the disc is returned to the rental outlet for use by another party.
  • DVDs, games or CDs are generally issued with a means for returning the article to the rental company, a so-called reply device.
  • This reply device or return means usually also involves using the postal service, which allows a rapid return of the DVD, game or CD for re-hire.
  • a key feature of this form of rental operation is that the machine readable data, such as for example the software, stored on the game, DVD or CD must be protected from damage during the transportation process, thereby enabling use of the particular articles a number of times. If the DVDs 1 games or CDs are damaged either at the point of receipt of the end user or upon return to the rental company then the whole rental system fails leading to disgruntled customers and loss of revenue for the rental company.
  • the current device for the mailing DVDs, games or CDs is not ideal, as it does not allow for automatic sorting of the package by barcode into postal districts nor machine sorting of the package by the postal authorities.
  • there is a further problem associated with the mailing of machine readable discs in that the postal system applies strict rules for the transportation of articles with the cost of transportation increasing greatly if the size, weight and form of packaging does not comply with the terms and conditions laid down by the postal delivery system.
  • any bulk mailing can be eligible for postal discounts by the Royal MailTM provided that the product conforms to certain criteria, in particular that the organisation mailing the item can perform 'pre-sorting' functions to various degrees.
  • the most cost effective and appropriate system is Royal Mail MailsortTM which attracts the most discounts.
  • the organisation preparing the mail and sending it out are required to, using proprietary software, pre-sort the address into MailsortTM districts as appropriate, each containing a unique numeric code, visible in the envelope. These are put into bundles, and then into labelled bags, all this occurs prior to the mail being collected by Royal MailTM. This removes the need for the majority of machine sorting by Royal MailTM.
  • the delivery device generally used for this application is a folded pocket, glued on two short sides to form an envelope. It comprises two sides with perforations along a crease line provided just off centre of the device. One side of the device has a position on the front of it where the outgoing delivery address is personalised, (by the mailing organisation or user), by either variable inkjet, laser printing or by means of a pre-personalised address label. A tab of adhesive material also extends down the remote edge.
  • the other side of the device has a disc 'pocket' for receiving the DVD, together with the address of the rental company and a strip of adhesive adjacent the central crease line.
  • the desired DVD held within a plastic or paper case or sleeve, is inserted into the 'pocket' and the sides of the device are brought together and secured by means of the adhesive tab for delivery to the customer.
  • the customer is then able to open the envelope by unsticking the tab and opening out the device to remove the disc from the pocket.
  • the side of the envelope displaying the delivery address is removed and discarded by tearing along the central perforated lines, the DVD is re-inserted into the pocket and the adhesive strip of material on the remaining side of the device is bent over and secured to this side.
  • This device has a number of disadvantages in that it does not allow pre-sorting by delivery address or sorting by the postal authority, due to the thin nature of the envelope resulting in it being too fragile to pass through mechanical sorting equipment, as it would allow damage to the disc.
  • the folder is only secured along two sides thereof.
  • mail carriers that are sealed around all sides, and comply with certain sizing, can qualify for bulk, machine sortable discounts, such as CleanmailTM, Cleanmail PlusTM, and Response PlusTM of Royal MailTM.
  • a further example of a means of protecting machine-readable discs exists in the form of a lightweight sleeve.
  • the sleeves are commonly manufactured as a simple open- ended wallet either with or without a window aperture.
  • Typical sleeves are comprised of a non-woven synthetic paper like material.
  • TyvekTM One example of this type of sleeve have been developed by DuPontTM Industries and marketed under the trade name TyvekTM for protecting DVDs and CDs.
  • Whist sleeves comprised of TyvekTM have been proven to be significantly more effective than any other material in protecting the data stored on DVDs, games and CDs from contamination, particularly by scratching, due to its non-abrasive smoothness and anti-static qualities, a major disadvantage of this form of product is that it is flimsy, is not impervious to marking and staining, and the appearance deteriorates rapidly with multiple use.
  • a sleeve produced solely from TyvekTM alone is unable to withstand the rigours of multiple mailings making a TyvekTM only sleeve unsuitable for the purposes of mailing and protecting games, DVDs and CDs.
  • Paper and cardboard sleeves have also been employed as a means of transporting and protecting machine-readable discs.
  • Such paper and cardboard sleeves like the TyvekTM sleeves, are typically manufactured, as a simple open-ended wallet (with or without window aperture), from a variety of cellulose substrates, comprising for example various gram weights and thickness of paper, through to board weights, with various finishes to the surface.
  • the main disadvantage of these cellulose-based substrates is that over time they generate fibres that abrade the data stored on the discs and hence lead to surface damaged discs with impaired readability.
  • flexible plastic wallets comprised for example of polyvinylchloride (PVC) have been mooted as an alternative to card and paper wallets these too have drawbacks.
  • PVC wallets exist which are manufactured as simple, open-ended, sleeves from two of more pieces or leaves, of flexible PVC.
  • the PVC material may be of various microns in thickness, with each leaf being welded or glued along three of its four edges.
  • PVC wallets have the advantage that due to the transparency of the material the disc may be viewed directly through the wallet, and PVC affords greater protection from breakage for discs contained therein, than, for example, either TyvekTM or paper product wallets, the PVC material is itself abrasive to the discs such that over time discs stored within the PVC sleeves can become unreadable due to scratching.
  • a further object of the present invention according to a second aspect of the invention to provide a method of manufacturing a mail carrier, such as a envelope, comprised for example of paper that may enable the carrier to be manufactured quickly and cheaply compared to the prior art.
  • a sleeve or pouch for storing and transporting machine-readable discs which delivers not just longevity through multiple use, but also importantly protects the contents of the sleeve from breakage and abrasion, and which is particularly suited for use via the mailing/postage process in combination with the mail carrier.
  • a method of preparing a sleeve or pouch for use in storing and transporting machine-readable discs which can be used numerous times via the mailing/postage process and which protects the contents of the sleeve from breakage and abrasion when used with the mail carrier.
  • a paper mail carrier formed from a web material, the carrier comprising a front panel and a rear panel, said front and rear panels being connected by fold lines and further comprising: at least one pocket formed in said front and/or rear panel for receiving an item, and means for releasably securing front and rear panels to retain the item in the pocket and wherein said means comprises at least one sealing flap securable to the front or rear panels forming the pocket and wherein the carrier is further provided with re-positional adhesive to ensure that all open sides of the paper mail carrier are sealable.
  • the postal mail carrier according to the first aspect of the present invention is formed from a web material, that is, it is a reel-fed, web-finished carrier wherein the product (roll or web of pre-printed paper) remains on a reel until final cross cuts are made to separate and arrange it into individual carriers.
  • the sealing flap is preferably secured to the front and or back panels using re- positional adhesive.
  • the sealing flap is further provided with a strip of adhesive material and/or a varnished paper strip to be peeled away to expose an adhesive to allow sealing.
  • the mail carrier further comprises an additional main body forming panel connected by fold lines to the front or rear panel, the panel comprising substantially the same dimensions as the front and rear panels. Furthermore, the additional main body forming panel is further provided with a sealing flap thereby forming a wrap-around panel that wraps around the front panel for sealing to the rear panel by means of the sealing flap.
  • At least one flap is provided for securing the front and rear panels together in the assembled carrier.
  • the flap is provided with a strip of adhesive material and/or a varnished paper strip to be peeled away to expose the adhesive to allow sealing.
  • the paper mail carrier further comprises a means for the return mailing of an item sent therein.
  • the carrier is provided with an additional main body forming panel connected by fold lines to the front or rear panel, the panel being substantially the same dimensions as the front and rear panels.
  • This main body forming panel is preferably provided with the sealing flap thereby forming a wrap-around panel for wrapping around the front panel and sealing to the rear panel by means of the sealing flap in the closed device.
  • the carrier includes means for return mailing of the item sent therein.

  • the panel having the pocket is preferably provided with an additional flap having means for securing the flap to the panel for re-closure of the carrier for return delivery, for example in a similar manner to the construction of the outgoing sealing flap.
  • the carrier will preferably be provided with a position on a front panel of the outgoing device where the outgoing delivery address may be applied by the user, such as by the way of variable inkjet printing, laser printing or by applying a pre-personalised address label.
  • a similar position will preferably be provided on a panel of the return delivery portion for application or display of a return delivery address.
  • the front and rear panels forming the pocket are preferably detachable from the adjacent additional panel so that the additional panel may be discarded and the front and rear panels forming the pocket comprise an additional sealing flap or return sealing flap having means for securing the flap to the panel for re-closure of the carrier for return delivery.

  • a strip of cohesive or re-positional glue is applied to each outer edge on the intended outer surface of the rear panel or front panel and to each outer edge of the intended inner surface of the front/rear panel or additional main body forming panel, depending upon whether the latter is included in the carrier.
  • Each strip is preferably the entire length of the panel.
  • the nature of cohesive or re-positional adhesive results in the strips being inert until a pair are mated together wherein they stick together sufficiently to close the piece but not so aggressively that they tear the paper when opened.
  • the carrier is folded closed, the two pairs of adhesive strips mate to form a re-peelable closure, resulting in all four sides of the carrier being closed for mailing.
  • Re- positional adhesive has the advantage that if used then the adhesive need only be applied to one surface. This is advantageous as mail carriers that are sealed around all sides may qualify for bulk mechanised mail postal discounts, such as CleanmailTM, Cleanmail PlusTM, and Response PlusTM of Royal MailTM.
  • the glue may be a low tack adhesive style, such as "post-it note” glue, in which it is applied to each open edge of one panel only, rather than to two opposing panel edges as required with cohesive glue.

Furthermore, when a disc is inserted as described above, the construction of the pouch ensures that the data side of the disc rests against a first surface of the non-abrasive (TyvekTM) layer, 301.

  • the pouch is prepared as described in relation to Figure 11 above with the following changes. Firstly, at least two holes 701 , 702 are created in the non-abrasive TyvekTM layer 301. The two layers of flexible plastics material 101 and 401 are then spot-welded together through these holes, indicated by 800 in Figures 7c, 8c and 9c. The holes (701 , 702) and welds (800) so formed are positioned towards the lower third of the pouch and act to form a 'stop' or "bumper" which a disc inserted into the pouch rests against.
  • the positioning of the holes and weld serves to prevent a disc inserted into the pouch from touching the bottom most weld line 60.
  • the presence of the holes and welds not only has the advantage that damage to the edge of the disc is prevented as a result of the disc rubbing against the bottom weld line 60, but also has the added advantage that the welds lock the TyvekTM sheet 301 into position, thereby negating the need to weld TyvekTM layer in place anywhere else. Consequently, the welding needed to construct the pouch is simplified such that the shorter length PVC strip (feed guide 201) is only welded on three sides, that is, 50, 70 and 80 (top and sides).
  • the top of the feed guide layer 201 is still welded to the fourth layer of PVC 401 of the pouch as previously described above however, the sides are also welded to a greater extent to strengthen the side welds, to a range between 20mm and 50mm, more preferably 25mm, measured from the top edge of the pouch.

  • 'bumper' holes Whilst in this preferred embodiment two 'bumper' holes are described in relation to forming a block or stop against which a disc may rest, it will be appreciated that alternatively, a number of 'bumper' holes could be formed in the TyvekTM layer and the first and fourth PVC layers welded together about the holes accordingly in a arcuate manner, across the TyvekTM layer to form a cup or dish into which the disc may rest.
  • the pouch comprises a further modification which relates to layer 201.
  • a portion of layer 201 has been cut away, for example, by means of a die cut process. It will be appreciated that this shaping of layer 201 is preferably made prior to assembly of the pouch by welding and involves removing a section of the layer 201. The removed section of layer 201 is preferably semi-circular in shape. The removal of a portion of layer 201 has the effect that there is no part of PVC layer 201 which is in direct contact with a disc when the disc is places inside the pouch.
  • an additional layer of flexible material 501 which is again shorter in length than the first 101 and fourth 401 layers of flexible material is employed.

  • This arrangement allows two machine-readable discs to be correctly inserted, that is, with the printed side of the discs facing outwardly, such that one of the discs may be read through the first layer of flexible (PVC) material 101 , and the second disc through the fourth layer of flexible (PVC) material 401 respectively, (assuming both layers are suitably transparent) while the data side of each disc rests against either side of the non-abrasive (TyvekTM) layer 301.
