[0001] The present invention relates to an envelope, particularly for containing sheets
and the like, with tamper-evident seal.
[0002] As is known, one problem that is currently strongly felt in the distribution of commercial
products placed in envelopes and the like relates to the assurance that the envelope
has not been fraudulently or unintentionally opened, possibly tampering with its content.
[0003] Considering in particular the field of envelopes or folders that contain drawing
sheets or the like, currently the envelope has an openable flap, which in the closed
position can be arranged below a fixed flap.
[0004] With a packaging of this kind, therefore, currently it is not possible to detect
whether the envelope has been opened fraudulently or unintentionally, and therefore
it cannot be ruled out immediately that sheets have been removed from the envelope
or that for example the sheets contained therein have been dirtied.
[0005] Application of pieces of adhesive tape in order to connect one another the fixed
flap and the openable flap has been found to be unable to fully solve the problem,
since any unauthorized opening cannot be easily detected visually and verified by
the buyer.
[0006] The aim of the invention is to solve the described problem, by providing an envelope,
particularly for containing sheets and the like, with a tamper-evident seal, that
allows to give great assurances of security regarding the complete integrity of the
envelope and of its content.
[0007] Within this aim, a particular object of the invention is to provide a containment
envelope in which unauthorized opening can be verified easily by an automatic apparatus,
which accordingly informs the buyer immediately of the fact that unauthorized opening
has occurred.
[0008] Another object of the present invention is to provide a containment envelope that
thanks to its particular constructive characteristics is capable of giving the greatest
assurances of reliability and safety in use.
[0009] Another object of the present invention is to provide a containment envelope that
can be obtained easily starting from commonly commercially available elements and
materials and is also competitive from a merely economical standpoint.
[0010] This aim and these and other objects that will become better apparent hereinafter
are achieved by an envelope, particularly for containing sheets and the like, with
tamper-evident seal, comprising an envelope-like containment body that forms a pouch
for accommodating a plurality of sheets that can be closed by an openable flap that
interacts with a fixed flap, characterized in that it comprises a tamper-evident seal
that can be arranged on said openable flap and on said fixed flap and which cannot
be restored once opened.
[0011] Further characteristics and advantages will become better apparent from the description
of a preferred but not exclusive embodiment of a containment envelope, illustrated
only by way of non-limitative example in the accompanying drawings, wherein:
Figure 1 is a schematic perspective view of a containment envelope for drawing sheets
that is intact and in the closed position;
Figure 2 is a schematic view of the step of the opening of the envelope;
Figure 3 is a view of the step of the extraction of the contained sheets;
Figure 4 is a view of the envelope in the fraudulently closed condition; and
Figure 5 is an enlarged-scale view of the detail of the tamper-evident seal after
it has been tampered with.
[0012] With reference to the figures, the envelope, particularly for containing sheets and
the like, with tamper-evident seal, according to the invention, comprises an envelope-like
containment body, generally designated by the reference numeral 1, which is advantageously
made of paper-like material and forms internally a seat or pouch 2 that can be closed
by an openable flap 3 that interacts with a fixed flap 4.
[0013] A plurality of drawing sheets, generally designated by the reference numeral 10,
can be accommodated removably within the seat 2.
[0014] The particular feature of the invention consists in that there is a tamper-evident
seal, generally designated by the reference numeral 20, which is constituted by a
self-adhesive label 21 that bears a code, for example a bar code 22.
[0015] In the closed position, with the package intact, as shown in Figure 1, the bar code
is perfectly readable by ordinary equipment provided at the point of sale.
[0016] Once opening occurs, the product identification code, constituted for example by
the bar code 22, being provided on the self-adhesive part of the label, is in practice
destroyed, remaining partly connected to the label and partly connected to one of
the flaps to which it had been applied; therefore, when the envelope is fraudulently
closed again, it is not possible to restore completely the tamper-evident seal and
accordingly the equipment provided at the cash registers to recognize the product
on sale are unable to read the label and therefore it becomes evident also to the
buyer that the package has been tampered with.
[0017] From the above description it is evident that the invention achieves the intended
aim and objects, and in particular the fact is stressed that the provision of a tamper-evident
seal constituted by a self-adhesive label that bears the product identification code
allows to make any tampering immediately detectable and does not allow fraudulent
restoring of the initial conditions.
[0018] Furthermore, the high degree of security achieved is obtained by using particularly
simple means, constituted as mentioned by a simple self-adhesive label that bears
the product identification code.
[0019] The invention thus conceived is susceptible of numerous modifications and variations,
all of which are within the scope of the appended claims.
[0020] All the details may further be replaced with other technically equivalent elements.
[0021] In practice, the materials used, as well as the contingent shapes and dimensions,
may be any according to requirements.
[0022] Where technical features mentioned in any claim are followed by reference signs,
those reference signs have been included for the sole purpose of increasing the intelligibility
of the claims and accordingly such reference signs do not have any limiting effect
on the scope of each element identified by way of example by such reference signs.
1. An envelope, particularly for containing sheets and the like, with tamper-evident
seal, comprising an envelope-like containment body (1) that forms a pouch (2) for
accommodating a plurality of sheets (10) that can be closed by an openable flap (3)
that interacts with a fixed flap (4), characterized in that it comprises a tamper-evident seal (20) that can be arranged on said openable flap
(3) and on said fixed flap (4) and cannot be restored once opened.
2. The containment envelope according to claim 1, characterized in that said tamper-evident seal (20) bears the product identification code (22).
3. The containment envelope according to one or more of the preceding claims, characterized in that said tamper-evident seal (20) is constituted by a self-adhesive label (21).
