Description

Envelope and method for opening an envelope.
The present invention relates to an envelope and a method for opening an envelope.
More specifically the invention concerns an envelope that is specifically intended to be opened automatically. In organisations where a lot of mail comes in, there are often machines for opening mail. They do not generally work in a similar way to a person who opens mail. A person inserts a somewhat pointed and flattened rod into an envelope, along an edge of it, and exerts a force with the rod that is partly oriented outwards, such that the envelope tears open.
A machine for opening mail on the other hand removes a narrow strip of material at an edge of the envelope, for example by cutting or milling, such that the envelope is opened."
It is of course important here not to damage the document in the envelope, but it must nonetheless be certain that the envelope is open, such that the adjustment of the machine is a difficult matter, whereby a balance must be found between the risk of damaging a document and the risk of a failed opening operation. Hereby the machine must of course be constructed such that the positioning of the envelopes is very accurate, whereby very small tolerances are required. Nevertheless damage regularly occurs to the documents in the envelope.
This can be improved by first performing a mechanical tapping movement on the envelopes, with the aim of placing the document inside well against the bottom edge of the envelope, in order to then remove the strip of material on the opposite edge.
However this does not always work well for very long, because not all documents have enough space in the envelopes, or do not slide sufficiently easily in the envelopes .
The purpose of the present invention is to provide a solution to at least one of the aforementioned and other disadvantages, by providing an envelope for a document," whereby in the closed state the envelope has four edges i.e. a top edge, a bottom edge, and two side edges, and whereby the envelope has a front and a back, and whereby the envelope is provided with a spacer on the inside at or close to at least one edge, in order to keep the document at a distance from the edge.
This has the advantage that, because the document is kept away from the edge by means of the spacer, this edge can be cut away with a reduced risk of damage to the document. As a result a machine for opening envelopes can be designed whereby accurate positioning of the envelopes is less critical and which can thus be simpler, and the adjustment of machines for opening envelopes is easier.
Also a vibration, knocking, shaking or tapping module to keep documents away from an edge of the envelope can be omitted.
In a preferred embodiment the envelope is provided on at least one edge with at least two such spacers, whereby the two such spacers, which are the furthest away from one another on the same edge, are at a distance from one another that is greater than 30% of the length of this edge .
Preferably this distance is greater than 50% and preferably even greater than 80%.
The advantage is' that a document can be kept away from an edge at at least two positions, such that an oblique positioning of the document in the envelope is prevented. Such an oblique position could lead to the localised touching of the inside edge by the document and thus to damage to the document upon opening.
In a preferred variant the envelope is provided with one or more such spacers on at least two edges that are located opposite one another. This enables the advantage to be achieved on two opposite edges so that an orientation step, by machine or manually, to orient the envelope before being opened by machine can be avoided.
In a further preferred embodiment the spacer has a distance to the edge concerned of 3 mm or less, preferably 2 mm or less, and preferably 1 mm or less. In this way the effective usable inside space of the envelope is not limited to any great extent, while the advantage is nonetheless obtained.
The distance is hereby defined as from the edge to the part of the spacer located furthest from the edge.
Practical embodiments of a spacer are
• a connection between the front and the back, for example by means of a small area with adhesive.
· an auxiliary body that is placed in the envelope and that is close to the edge in the envelope, for example a pellet or cylinder that is made of paper or a papery material, for example.
• an inward-protruding deformation of, or a thickening that is affixed to, the material from which the envelope is manufactured.
In a further preferred embodiment, the envelope is provided with an indication on the outside to indicate at which edge or edges the envelope is provided with a spacer. In this way it is easy to ensure the correct orientation of the envelope when feeding it into a machine for opening envelopes. The indication can be made such that it can be recognised by machine, so that the correct orientation can also be ensured by machine.
The invention also concerns a method for positioning a document in an envelope, whereby the envelope has a front and a back and four edges, i.e. a top edge, a bottom edge and two side edges, whereby use is made of at least one spacer present in the envelope in order to keep the document at least at a distance from an edge defined by the spacer . The invention also concerns a method for taking out a document from a closed envelope, whereby the document is positioned by means of the above method, whereby a strip of envelope material is removed from the edge and whereby the width of the strip that is removed is less than or equal to the said distance.
With the intention of better showing the characteristics of the invention, a preferred embodiment of envelopes according to the invention is described hereinafter by way of an example, without any limiting nature, with reference to the accompanying drawings, wherein:
Figure 1 schematically shows a perspective view of an envelope according to the invention;
Figure 2 shows a cross-section of a part of the envelope of figure 1 according to line II-II; Figure 3 shows a cross-section of the part of figure 2 according to line III-III;
Figure 4 shows a part of an alternative envelope according to the invention, in a cross-section corresponding to the cross-section of figure 3;
Figures 5 to 9 show the use of an envelope according to figure 4;
Figures 10 and 11 show a part of a further alternative envelope according to the invention, in cross-sections corresponding to the cross-sections of figures 3 and
4;
Figure 12 shows a further alternative envelope according to the invention, in a view corresponding to figure 1;
Figure 13 shows a cross-section according to line
XIII-XIII of the envelope of figure 12;
Figures 14 to 16 show a part of a further alternative envelope according to the invention, in a cross- section corresponding to the cross-section of figure 3 and two side views;
The envelope 1 of figures 1 to 3 is essentially made from a layer of paper 2 and comprises a front 3, a back 4, a top edge 5, a bottom edge 6 and two side walls 7. A wide dark line 8 is affixed close to the bottom edge 6 on the back 4. The envelope has a length L.
Three spacers 9 are affixed spread over the length L, whereby the two outermost spacers 9 are at a distance from a side edge 7 that is approximately 10% of the length L, such that the distance between them is approximately 80% of the length L. The spacers 9 are affixed at a distance A of 2 millimetres from the bottom edge 6.
The spacers 9 are formed by a quantity of adhesive 10 that connects the front 3 and back 4 together. This quantity of adhesive 10 can be hotmelt adhesive, for example, that is applied over a larger area to the inside of the front 3 or back 4, and which is melted by means of pointed heat sources during manufacture of the envelope 1 to form the spacers 9.
The alternative embodiment of the envelope 1 shown in figure 4 differs from the envelope 1 according to figures 1 to 3, by an arched cut 11 being made in both the front 3 and the back 4, that runs around the spacer 9 and ends at a distance B of approximately 0.5 mm above the bottom edge 6.
The use of the envelope 1 of figure 4 is illustrated on the basis of figures 5 to 9.
Figure 5 shows a cross-section of a closed envelope, in which there is a document 12 and whereby it is the intention for the envelope to be opened in a machine for opening envelopes.
As shown in figure 6, this machine makes a straight cut 13 through the front 3 and back 5, at a distance S of approximately 1 mm from the bottom edge 6. As a result a strip 14 of paper of width S, that previously formed the bottom edge 6 of the envelope 1, is cut away from the rest of the envelope 1, as shown in figure 7. As a result there is still a large distance between the straight cut 13 and the document 12, which is kept away from the bottom edge 6 by the spacers 9, so that inaccuracies in the machine or its operation do not lead to damage to the document 12.
Alternatively such a strip 14 can be removed by another removal technique, for example milling.
As shown in figures 8 and 9, thanks to the arched cut 11, the spacer 9 is no longer connected to the rest of the envelope 1. As a result the envelope 1 is completely open on its underside and the document 12 can easily be taken out of the envelope 1.
As a result of the darker line 8 on the back 4, it is easy to find the correct orientation of the envelope 1 for the correct insertion into the machine for opening envelopes.
This applies to insertion into this machine by a person or by an automated feeder that is equipped with a sensor to identify the darker line 8 and an auxiliary device to adjust the orientation of the envelope 1. The darker line 8 hereby forms an indication of the edge that is provided with a spacer 9, in this case the bottom edge 6. When an envelope 1 according to figures 1 to 3 is opened in this way, the spacers 9 remain connected to the rest of the envelope 9, due to the lack of an arched cut 11 and they still form a limited obstacle to the removal of the document 12 from the envelope 1. However, in order to be able to take a document 12 out of the envelope, the front 3 and back 4, at the location of the opening created by the removal of the strip 14, must be moved away from one another in order to have space to grip the document 12 and let it slide in the envelope 1.
The spacers 9 are applied to such a small area of the front 3 and back 4, that when the front 3 and back 4 are manually or mechanically moved away from one another, these spacers 9 and/or the paper 2 around them easily break or tear so that the envelope 1 is completely open on the underside, such that the small obstacle does not present any problem in practice.
The alternative embodiment of the envelope 1 shown in figures 10 and 11 differs from that of figures 1 to 3 by not being provided with spacers 9 that are formed by adhesive 10. Instead of this, the envelope 1 is provided with one or more ridges 15 that are made in the paper 2, for example by embossment or another deformation technique, before this paper 2 is made into an envelope 1.
A spacer 9 is now formed by the part 16 of the ridge 15 that is between the front 3 and the back 4, thus above the middle of the bottom edge 6. When removing the strip 14 with the bottom edge 6 of this envelope 1, the underside is fully opened, except perhaps for a few very weak connections formed by ridges 15. Alternatively the ridge 15 can be formed by a number of smaller inward-oriented bulges located next to one another, whereby the ridge 15 or the bulges can be formed by deformations of' the paper, or by applied thickenings of the paper .
It is advantageous here if the ridge 15 extends up to the top edge 5 via the front 3 and back 4, because the ridge 15 can easily be made continuously in or on the paper 2 on a roller, and the ridge 15 keeps a document 12 away from the front 3 and back 4 so that if the envelope 1 becomes soiled or wet, it is transferred less easily to the document 12.
The alternative embodiment of the envelope 1 shown in figures 12 and 13 differs from the earlier embodiments shown, by there being two spacers 9 that are formed here by connections between " the front 3 and back 4 that are constructed as Z-shaped folded strips 17.
These strips 17 each consist of three parts 17A, 17B, 17C, whereby the outermost parts 17A, 17C parallel to the back 3 and front 4 are glued thereon. Hereby the outermost parts 17A, 17C of the same strip 17 are secured at a different height above the bottom edge 6. The two strips 17 are hereby secured to the front 3 and back 4 in a reflected orientation with respect to one another. The advantage of this is that when removing the bottom edge 6 the strips 17 are cut through so that the envelope 1 can be easily opened, but that the remains of the strips 17 remain connected to the envelope 1 so that few paper shreds are formed.
Although the envelope 1 in figures 12 and 13 is only provided with two such spacers 17, it is of course possible to use a larger number. Hereby the use of a number of pairs of mutually reflected affixed strips 17 spread over the length L appears particularly attractive, because a document placed in the envelope 1 can be held up better so that there is space to cut through the spacers 9 formed by the strips 17 without touching the document. The use of this envelope 1 is similar to the envelopes 1 described above. After removing the strip 14 the pellets 17 are no longer wedged. This means that irrespective of the fact whether the straight cut 13 is made above, below or through the pellets 17, the pellets 17 are completely clear of the paper 2, so that there can be no remaining connection between the front 3 and back 4, and so that immediately after removing the strip 14 the envelope 1 is completely open. The alternative embodiment of the envelope 1 shown in figures 14 to 16 differs from the embodiments shown earlier, because a spacer 9 here is formed by two folded lips, i.e. a top lip 18 and a bottom lip 19 respectively, formed by material of the back 3 and front 4 respectively. These lips 18, 19 are formed by making U-shaped incisions 20 in the front 3 and back 4, whereby the open side of the U-shaped incision 20 is oriented downwards in the front 3 and oriented upwards in the back 3, and then the parts of the front 3 and back 4 cut around are folded inwards to form lips 18, 19.
The use of this envelope 1 is similar to the envelopes 1 described above, whereby a fixed connection between the front 3 and the back 4 is not brought about, so that complications with opening the envelope 1 after removal of the strip 14, however slight they may be, are prevented.
Although not shown in the drawings, spacers 9 can also be affixed to more than one edge 5,6,7. If they are affixed to two edges opposite one another, this has the advantage that the orientation of the envelope 1 in a machine for opening envelopes is no longer critical.
Depending on the distance between the front 3 and back 4 at the location of the spacer 9 and the thickness of the document 12, the minimum distance that the document 12 has from the bottom edge 6 can be greater in practice than the distance between the spacer 9 and the bottom edge 6. For the good functioning of an envelope 1 according to the invention it is not necessary for a document 12 to physically rest against the spacer 9, although with relatively thick spacers 9 and/or relatively thin documents 12 this is not excluded either. The present invention is by no means limited to the embodiments described as an example and shown in the drawings, but an envelope according to the invention can be realised in all kinds of variants, forms and dimensions without departing from the scope of the invention.
