Abstract

The envelope folder (1) has first cover portion (2) and a second cover portion (4) which forms an envelope. The variable width (B) is set at back portion (3) formed between cover portions. The cover portions have a slip (5) to compensate for changes in size of the cover portions due to changes in the width on the cover portion along displacement path (7), so that the effective size of the envelope is variable. A fixing element (6) is arranged between the cover portions and slip, so that slip is fixed in any position relative to the cover portions on the displacement path.

Description

The present invention relates to a customizable envelope folder. Such folders are used to hold a stack of paper that may have a different height and thus requires a variable spine width of the folder, so that cover the front and back envelopes at any height of the paper stack up to the maximum recordable height, the paper stack by level edition of the envelope. Resizable envelopes are known in the art.

A typical and frequently used basic form, in which the back has a plurality of parallel folded grooves, of which a height determined for a paper stack is optimally suitable for kinking the back of the folder cover, describes the DE 833 031 B , The back part of the folder is folded or crimped in the usual way, so that it is flexible and possibly also somewhat stretchable, in order to allow adaptation to thicker document stacks.

However, from the outset no optimal covering the paper stack covering possible or with increasing spine width, the size of the front envelope is reduced, so that no more optimal protection is guaranteed for lack of complete coverage of the surface of the paper stack. In addition, the front and the rear envelope are then different sizes, which is at least detrimental to the visual appearance.

The DE 196 20 506 B4 also describes a typing collection folder having a lid and a bottom which communicate via a spine whose width is variable by a strain stock. When changing the surfaces of the lid and bottom remain constant, since the expansion reserve is obtained from a plug-in, which with Lid and back is integrally formed and is inserted into a pocket in the ground. With a size-adjustable envelope folder of the type described a constant size of the envelope is secured, even if the width of the back varies with the height of the paper stack.

In this closed, complicated to be manufactured bag, the insertion tab can move freely over the predetermined and limited by an elaborate folding of tabs and pocket displacement, so that the tab can not completely slip out of the bag. However, this also results in the disadvantage that the tab can continue to slide out of the pocket as desired. A fixation in the desired position is not possible. Among them suffer the reliability and dimensional stability of the portfolio.

The DE 10 2008 055 493 A1 also describes a size-adjustable stretch folder with an inner part and a slide pocket, which are telescopically slidable. However, since the pouch is completely closed from the point of manufacture, documents can get stuck in it and go undetected.

The adjustable envelopes of the prior art have the disadvantages that either the surface of the lid or bottom in the adjustment of the spine width does not remain constant, usually the lid only at minimum spine width has the same area as the ground, otherwise this surpasses or stands behind. If this problem is solved and the surface of the lid and bottom constant, in turn suffers the reliability under the adjustment to the extent that it lacks a Fixiermöglichkeit. Another disadvantage is the complex production of the used pouches and the Risk that documents will disappear and not be rediscovered.

This results in the task to offer a customizable envelope that has an adjustable back and in addition the envelope sizes are adjustable and this setting is also fixable.

The object of the invention is achieved by an adaptable envelope with a first and a second cover element forming the envelope, a arranged between the lid elements back with a variable width, which is integrally connected to at least one of the cover elements in such a way that the back in the Widening is at least partially formed from a pointing towards the back part of the cover element, and wherein this cover element has a slip, which is arranged to compensate for changes in the size of the lid member due to changes in the spine width on the cover element along a displacement path, so that the effective size of the envelope is changeable, wherein at least one fixing element is arranged to act in the manner between the cover element and the drawer, that the slipcase can be fixed in any position relative to the cover element on the displacement section.

This ensures that the envelope on its front and back is adjustable to a matching size, even if a part of the lid member, for example, has passed over by folds on creases for spinal widening in the back. It is particularly advantageous that the adjustment remains by means of the fixation. The fixation is preferably carried out by gluing, such as glue sticks with pasty or liquid adhesives.

It is also advantageous if the at least one fixing element is detachable on one side again. In that case, if the number of sheets in the envelope folder changes again, which is accompanied by a change in the width of the back, the size of the envelope can be adjusted again. For this purpose, the fixations between the cover element and slipcase are released, the slip is brought into the new position and fixed again.

It has proven to be advantageous if the at least one fixing element is designed as a self-adhesive strip, the cover element and slip bindingly adhering to a first surface and removably adheres to a second surface. Self-adhesive strips are known in the art, inexpensive and readily available. The changing functions in terms of removability can be easily realized by the surfaces of the cover element and slipcase are designed accordingly. A rough surface, preferably on the inside of the slipcase, prevents the renewed detachment, so that the fixing element is permanently attached in this area. If the respective other element, for example, and particularly preferably the cover element, is provided with a smooth surface, this allows easy detachment from the adhesive strip, which serves as a fixing element.

The self-adhesive strip may also be initially coated with a masking paper, so that the user can determine when the fixing function is to be activated by peeling off the masking paper.

Alternatively, the at least one fixing element is designed as a Velcro strip, wherein a first element of the Velcro strip is connected to the cover element and a second element of the Velcro strip with the slipcase. It is sufficient here to use the one element, for example the cover element, to attach a small surface Velcro, on the other element, such as the slipcase, in contrast to attach a band-shaped Velcro, which expands in the direction of the displacement distance. Through the use of Velcro it is no longer necessary to the surface design to realize the Wiederablösefunktion, it is alone sufficient secure attachment of the Velcro tape required.

The object of the invention is further achieved by an adaptable envelope folder according to the preamble of the invention, wherein a stitching tongue is connected to the slipcase and partially protrudes through sliding slots, and wherein the length of the sliding slots dictates the length of the sliding path of the slipcase relative to the second cover element. As a result, the slipcase can no longer slip out of its guide, even if no cover flaps are provided, so that in an alternative embodiment, these can also be dispensed with. In addition to the fixing function, by means of which the back width can be variably and steplessly adjusted, the stitching tongue in a particularly advantageous manner offers a stapling function, so that perforated sheets can be stapled there.

The attachment of the stitching tongue can be done by riveting, gluing or any other known manner. It is particularly advantageous if a self-adhesive stapling tongue is attached to the slipcase. Then arise on the outer edges and surfaces no disturbing edges or projections; The surfaces remain intact and visually appealing. In addition, the production and repair, if the stapling tongue has become unusable once, very simple. Due to the dense adherence of slipcase and cover element by means of the stitching tongues is also reliably avoided that leaves fall in between and then no longer be found by the user.

It is also advantageous if the slipcase has a guide for limiting the dimension of the movement to the direction of movement of the displacement path. As a result, the fixation can be limited solely to the displacement movement between the cover element and the slipcase, so that only very few or very weak fixing elements must be used. Furthermore, the always parallel position of the slipcase to the outer edges of the other elements of the envelope folder, in particular the cover element, can be ensured without additional effort.

It is particularly favorable if the slipcase has a guide on the cover elements in the form of lateral flap flaps. These are made with the slipcase in one piece, preferably already prefolded and need only be folded around the lid member or pushed in the folded state on the lid member.

Particular advantages result from the fact that the slipcase has an inner lid in addition to the lateral flap. Through the inner lid of the slipcase, the cover element is completely enclosed by the slipcase, except for the insertion opening for the cover element. In addition, since the inner lid is easy to open, additional documents, in particular individual sheets, can be stored here and still remain easily accessible. The side flap covers ensure that the leaves can not slip sideways.

Furthermore, it is advantageous if the inner lid is connected to the lateral flap by at least one fixing element, in particular according to claims 2, 3 or 4. As a result, the inner lid can not open independently and release the documents stored therein. The opening must be against the holding force of the Fixing deliberately done by the user. As a result, the documents stored in the inner lid of the slipcase documents are particularly well secured.

Special advantages also arise when the inner lid has a viewing window. Then the document in the inner lid, without this open, remain visible. Thus, the inner lid can act in the sense of an interchangeable inner cover page.

To be particularly advantageous has been found when the slipcase is designed as a second envelope with lid elements and back. Particularly preferred are two identical envelopes same size. As a result, the production cost is reduced significantly, since only a single type of envelopes needs to be produced. To produce a slipcase, the second envelope folder simply has to be pushed onto the cover element of the first and serves as a slipcase in the folded state.

Thus, both envelopes can be used individually and without slipcase, especially with little content. If the content grows in a folder in such a way that it widens the back and thus to a shortening of the cover element, the second folder can be used as a slipcase and compensate for the loss of turnover area by reducing the size of the cover element.

Thus, the customizable envelope folder according to the invention allows a very simple production and efficient storage. This results in a reduction of costs and production costs. In addition, the user can make even customizable, resizable envelopes by simple handling according to his needs with existing envelope folders, as two Envelope folders a changeable envelope folder can be produced.

Additionally or alternatively, at least one flap has a stitching tongue to which punched sheets can be stitched. For this purpose, the stitching tongue is attached to the envelope flap, for example by riveting or by a self-adhesive stapling tongue. It is particularly advantageous if the stitching tongue is passed through slots through the flap, so that the fastening remains invisible and only the tongue ends protrude from the flap for bending over. Such a stitching tongue can be optionally attached to each of the flapper flaps.

Further advantages result from the fact that the maximum extension of the envelope size is not limited by an end position, for example by a stop. The required extension is determined solely by the size change of the lid member.

An additional reinforcement of the cover element is made by the slipcase with its two closed walls and side flaps. The envelope folder according to the invention is also particularly suitable for ordered subdivisions within organizational folders with characteristic self-adhesives.

Fig. 1a shows a schematic representation of an embodiment of an unfolded envelope according to the invention 1 in front view with a small width of the back 3. The first cover member 2 forms the bottom of the envelope 1, to which the back 3 is connected. The lid member 4 forms the upper envelope and at the same time, if necessary, a part of the back 3, which - visible in the figure - is equipped with fold lines. Along the fold lines, the second cover element 4 can be bent so that the desired width B results. If thereby the length of the second cover element 4 decreases in such a way that a complete covering of the cover element 2 can no longer take place, the slipcase 5 compensates for this by being pushed so far forward, according to the invention, the first and the second Cover element have substantially congruent dimensions.

The slipcase 5 is displaceable on the second cover element 4 along the displacement path 7. Is the desired position set, in which preferably the upper envelope exactly with the bottom, the first lid member 2 terminates, the slipcase 5 is fixed. This is done by the fixing elements 6. In the present embodiment, two fixing elements 6, designed as adhesive dots, consisting of self-adhesive strips, are provided. These are firmly glued to the slipcase 5 and preferably initially covered on the opposite adhesive side with a masking paper. If the masking paper is removed, the fixing element 6 is activated. The now adhesive-active side of the self-adhesive strip adheres to the smooth surface of the second cover element 4 and fixes this relative to the slipcase 5. Thus, the slipcase 5 is no longer relative to the second cover element 4 slidably.

However, the pressure-sensitive adhesive between the smooth surface of the second cover element 4 and the fixing element 6 is detachable, so that upon a change in the width B of the back 3 and the concomitant need to extract more areas of the second cover element 4 from the slipcase 5 and as back 3 to use, the fixation can be solved by the fixing elements 6.

Fig. 1b shows a schematic representation of an unfolded envelope according to the invention 1 in front view with a larger width of the back 3 for receiving a larger pile of paper in the envelope folder 1. For this purpose, the slipcase 5 has been further deported on the displacement path 7 of the second cover member 4 and gives a larger area of Back 3 with the recognizable fold lines free. Also in this position, the slipcase 5 can be fixed by the fixing elements 6.

Fig. 2 shows a schematic representation of an embodiment of a closed envelope according to the invention 1 in side view from below with larger Width of the back 3. Shown is the envelope folder 1 with a higher paper stack 14, which makes a larger width B 'of the back 3 is required. The paper stack 14 lies on the bottom, the first cover element 2, while for the formation of the back 3 already a part of the second cover element 4 is required. Therefore, the second cover element 4 has been pulled out of the slipcase 5 by the amount of the width B 'of the back 3. The fixing element 6 now ensures a fixation between the slipcase 5 and the second cover element 4, so that they are no longer mutually displaceable in the direction of the displacement path 7. Thus, the envelope formed by the slipcase 5 closes off exactly with the bottom and an envelope folder 1 is formed that optimally protects the paper stack 14.

In order to ensure the solubility of the fixing element 6, which is designed as an adhesive strip, this is on the first surface 12, which has a smooth structure, solvable, while it on the second surface 11, which has a rough structure according to the embodiment, not releasably glued.

In an alternative embodiment, the replacement of the adhesive strip is provided as a fixing element 6 by a Velcro strip. Then the structure of the surfaces 11, 12 and importance, since each Velcro element must be firmly connected with its back with the surfaces 11, 12. The solubility of the fixation then results from the solubility of the known Velcro connection.

Fig. 3 shows a schematic representation of an embodiment of a slipcase 5, which is pushed over a cover element 2, 4. The fixable by means of the fixing element 6 displacement takes place again along the displacement path 7 on the second cover element 4. The slipcase 5 in this case has an inner lid 4 ', the is also suitable for receiving additional, individual sheets of paper.

In this case, a second envelope folder 1 'is particularly preferably used as a slipcase 5. In this case, the first cover element 2 'of the second envelope 1' forms the outside of the envelope 1, while the inner lid 4 'of the slipcase 5 corresponds to the second cover element 4' of the second envelope 1 '. Between the first cover element 2 'and the second cover element 4', the back 3 'extends.

Fig. 4 shows a schematic representation of an embodiment of an unfolded inventive first envelope folder 1 in front view with an enlarged width of the back 3 and a second envelope folder 1 ', which is used as a slipcase 5.

In the illustration, the inner lid 4 'is opened and ready to receive a paper sheet or document. The detachable closure between the envelope flaps 8 of the slipcase 5 and the inner lid 4 'is effected by further fixing elements, in the embodiment, the Velcro 9, 10, which consists of a first element 9, for example, the barbs side, and a second element 10, for example, the loop side, consists.

The slipcase 5 is in the preferred embodiment, the envelope folder 1 ', identical to the envelope folder 1. Therefore, the inner lid 4' of the slipcase 5 here also the second cover member 4 'of the envelope folder 1'. While the envelope flaps 8 of the envelope folder 1 prevent the contents from slipping sideways, the envelope flaps 8 'of the second envelope folder 1' serve to guide the slipcase 5 on the second lid element 4.

The inner lid 4 'has in the illustrated embodiment, a viewing window 13 through which the inserted document remains visible. Thus, the slipcase 5 in connection with the second cover element 4 fulfills the function of a cover page with exchangeable content. Accordingly, the slipcase 5 can also be pushed onto the second cover element 4 in reverse, so that the viewing window 13 reaches the outside of the envelope folder 1. Thus, the inserted document serves as an exchangeable cover sheet. Alternatively, the viewing window 13 is inserted into the cover element 2 '.

Fig. 5 schematically shows a further embodiment of an envelope folder 101 according to the invention in the unfolded state. In this case, a self-adhesive stitching tongue 106 is attached to the inside of the slipcase 105, on the first cover element 102. Their ends protrude through two displacement slots 107 in the second cover element 104. The longitudinal extent of the sliding slots 107 determines the length of the sliding distance in the relative movement between the second cover member 104 and the slip 105 for changing the width of the back 103 and simultaneously forms stops for the two ends of the sliding distance.

As a result, a particularly simple and inexpensive production is possible. Furthermore arise in the outer surfaces of the envelope folder 101 no disturbing edges or projections. Furthermore, by stronger pressing of the stitching tongue 106 against the second cover element 104 a locking can be achieved in such a way that a further displacement of the slip 105 is prevented at any point. Thus, the envelope folder 101 is releasably fixed in the relevant position. At the same time, a stapling operation is possible in which perforated sheets can be stapled to the stapling tongue 106. In addition to Stapling function, the locking function is secured. The stitching tongue 106 hold the first cover element 102 of the slipcase 105 tightly against the second cover element 104. This prevents documents from getting into the gap and from being found there again. Furthermore, it is alternatively possible to provide the inner lid 110 of the slipcase 105 with a perforation and to guide the stitching tongue 106 here. Thus, the slip 105 can be closed.

The flap flaps 108 may alternatively or additionally be provided with a stitching tongue 106. For this purpose, the stitching tongue 106 is inserted into the envelope flap slots 107 and fixed there by means of the adhesive surface of the stitching tongue 106. This makes it possible to staple leaves punched on the narrow sides there. Thus, they can be scrolled up or down in an alternative manner on the narrow side, as may be advantageous for example, in long, extending over several pages tables, and are nevertheless staked firmly and securely in the envelope 101.
