Description

[Detailed explanation of the idea] The present invention relates to envelopes with tear-off paper strips.

2. Description of the Related Art Conventional envelopes with tear-off paper strips used for photo development and print request envelopes (hereinafter referred to as DP bags) are usually constructed as shown in FIG.

That is, the backing paper leaf 1 and the backing paper leaf on the back side are adhered by the adhesive part 2 along both side edges and the bottom edge to form a bag, and the surface of the backing paper leaf 1 has perforations 3 for separation. A plurality of slip forming paper pieces 4 are adhered so as to be separable along the .

On the other hand, a cover piece 5 is connected to the opening edge of the backing sheet 1 by a tear-off perforation 6, and a backing sheet 7 is connected to the opening edge of the backing sheet 1 with or without the tear-off perforation. There is.

In an envelope having the above structure, when used as a DP bag, for example, the cover piece 5 is used as a receipt at the perforation 6.
It is cut out along the lines and given to the client, and in some cases the backing paper piece 7 may also be cut out.

In this way, when the paper strips 5 or 7 are separated, and when the opening is widened to accommodate the contents inside the envelope, the upper end of the adhesive section 2 between the front and back sheets attempts to peel off the adhesive section. Forces are applied and the envelope is often peeled away at the adhesive top edge, resulting in the condition shown in phantom 8.

Once this happens, the adhesive portion 2 is increasingly peeled off as the contents are continuously taken in and out of the envelope.

Therefore, with conventional envelopes, great care must be taken when widening the opening sufficiently to check the inner fit when accommodating the contents, and when separating the pieces of paper 5 or 7. Even with the above precautions, peeling often occurred.

In view of the above points, the above problem does not occur even if special care is not taken when separating the paper strips and storing the contents, and the opening is sufficiently widened for confirmation of the internal law. It is an object of the present invention to provide an envelope with tear-off paper strips that can be separated.

Embodiments of the present invention will be described below with reference to the drawings.

2 to 7 show a first embodiment of the present invention.

The envelope shown in FIG. 7 is finally obtained, and this envelope has a continuous form F for forming the cover sheet shown in FIG. 2, a continuous form R for forming the back sheet shown in FIG. 3, It is composed of a continuous form D for configuring slip paper pieces shown in FIG.

The continuous form F for cover leaf composition is as shown in Fig. 2.
Margin 12.12 with feed tractor holes 11 delimited by longitudinal perforations 10.10 along both edges
It is equipped with

As is well known, this continuous form F is the tractor hole 1.
1 in its longitudinal direction (vertical direction).

The continuous form F has a vertical perforation 14 in the center for separation.
, and further has horizontal bursting perforations 15.
It also has

Vertical perforations 14 create a continuous form with equal left and right paper sheets 16.
, 16.

Near each end of the transverse perforation 15 of each sheet 16 are a pair of symmetrical wide long cuts 1 in the longitudinal direction of the continuous form.
7 is formed.

One end of the cut 17 overlaps the horizontal perforation 15, and the other end forms a wedge-shaped cut 18 with a sharp tip.

On the other hand, at a position somewhat closer to the horizontal perforation 15 than the sharp end of the cut 18, another horizontal perforation 19 for separation is formed across the pair of cuts 17.

The continuous form R for composing backing sheets shown in FIG.
It has a margin 12 with a feed tractor hole 11 separated by 0, and a central vertical perforation 14
and horizontal perforations 15 for bursting.

Adhesive portions 22 are provided in a U-shape inside the perforations 14 and 15 along the bottom and side edges of the paper sheets 20 of the same size on both sides of the vertical perforations 14. .

The continuous form D for constructing slips shown in FIG. 4 is made up of a plurality of (four in the illustrated example) similar forms stacked one on top of the other.

Each form has 10 vertical perforations, similar to those described above.
Tractor hall 11. Margin 12, vertical perforation 14
It is equipped with

These uniform forms have horizontal perforations 24 for separation along the vertical perforations 10 near the left and right edges, and there is a mutual separation between these perforations 24 and the vertical perforations 10 by, for example, line glue 25. is glued to.

The three types of continuous forms F and R1D described above are combined as shown in FIGS. 5 and 6 to construct the envelope with tear-off paper sheets of the present invention.

This combination is performed as follows. First, the U-shaped adhesive portion 22 is applied to the continuous form R for forming the backing sheet by a gluing device (not shown) while being continuously fed.

Next, the continuous form F for forming the cover leaf, which is being continuously fed in the same way, is superimposed on the surface of the continuous form R for forming the backing sheet, which is being fed further ahead, and both forms F and R are overlapped. It is passed through a press device (not shown) and subjected to a press operation.

When the adhesive part 22 is made of, for example, a heat-sensitive adhesive, heat is applied along with pressure in a press device, and the upper and lower continuous forms F and R are adhered to each other by the adhesive part 22.

Next, by a device (not shown), on the surface of each sheet 16 of the continuous form F for forming a cover sheet, a slip of slip paper separated by the vertical perforations 14 of the continuous form D for forming a slip of slips and with the margin 12 removed is placed. 27 is the perforation 24
It can be attached using line glue 25 on the outside of the .

The continuous form combination obtained in the above manner has slips of slip paper 27a, 27b, 27c,
27d is attached.

The continuous form combination obtained in the above manner has already been printed with the necessary data by a computer at the stage of being divided into each continuous form.

The continuous form assembly is then cut at the margin 12 along the vertical perforation 10, and then along the vertical separation perforation 1.
4 and bursting along the transverse perforations 15 to finally obtain the envelope with tear-off pieces shown in FIG.

The envelope thus obtained has a cover piece 28 connected to the envelope opening of the cover leaf 16 via a tear-off perforation 19, and long cuts 17 are placed on both sides of this paper piece 28 to separate the front and back sides. There will be a glued strip 29 of the sheet 16.20.

A wedge-shaped notch 18 is formed at the inner end of the long notch 17 and extends from the tear-off perforation 19 toward the bottom edge of the envelope.

On the other hand, on the surface of the cover leaf 16 are slip paper pieces 27a, 2
7 b , 27 C, and 27 d are attached along the perforations 24 so that they can be separated.

An example of using the above-mentioned envelope with tear-off paper strips as a DP bag will be described below.

In this case, the cover piece 28 is used as a receipt, and the slips 27a, 27b, 27C, and 27d are
Each of these is used as a DPE processing slip in a photofinishing laboratory, an order receipt for a DPE dealer, a delivery note, and a receipt, and a detailed column is provided on the cover page 16, respectively.

On this DP bag, the DPE dealer code number, store name, order number, etc. are printed out in advance by a computer, and at the photo lab, this DP bag is distributed to the DPE dealer in advance. Upon receiving a request from a customer, the operator tears off the cover piece 28 as a receipt, hands it to the customer, puts the film in a DP bag, and sends it to the photo lab.

At this time, the DPE dealer fills in the data necessary for processing at the photo lab on the topmost slip 27a, but the data from slip 27b onwards are made of pressure-sensitive copying paper or the like. The generated data is copied onto the second and subsequent slips 27b, 27c, and 27d.

At the DPE store, the slip 27b as an order receipt is cut off and left at the store.

At the photofinishing laboratory, after the processing is completed, the product is placed in a DP bag, the slip 27a serving as a post-processing slip is cut off, and a billing statement for processing costs is prepared.

The DP bag containing the product is then returned to the DPE dealer.

At the DPE store, after receiving the DP bag with slip paper slip 27C as a delivery note,
Cut out d and give it to the photo lab.

Thus, the DPE dealer will be able to hand over the product to the customer while comparing it to the details section on the cover page 16.

The above is an example of using an envelope as a DP bag,
The number and purpose of the slips 27 can be changed as desired.

According to the present invention, it is possible to completely eliminate the problems of conventional envelopes related to the operations of separating the cover piece 28 from the envelope and opening the envelope to take out and take out the contents.

That is, when separating the cover sheet 28, the force applied to the adjacent envelope portion through the end of the horizontal perforation 19 acts only on the portion of the sheet 16 that is inside the wedge-shaped cut 18, and 16 and the adhesive portion 22 of the backing sheet 20, in particular the two upper strips thereof, are subjected to almost no force.

Therefore, it is impossible for the adhesive portion 22 to peel off.

Furthermore, even if the opening of the envelope is widened to take out and take out the contents, no peeling force is applied directly to the adhesive portion 22 due to the wedge-shaped notch 18, which is different from conventional envelopes.

FIG. 8 shows an example of fabrication of an envelope substantially the same as that shown in FIG. 7, but in a continuous form in the lateral direction, unlike the case shown in FIGS. 2 to 6.

That is, in the case of FIGS. 2 to 6, the sheets 16, 20 constituting the envelope are arranged in the vertical direction of the continuous form, but in this example, the sheets 16, 20 are arranged in the horizontal direction of the continuous form. Ru.

In this example, the slip paper pieces 27a to 27d are pasted with line glue 25A instead of spot glue.

FIGS. 9 and 10 show a second embodiment in which the long cut 17 and wedge-shaped cut 18 of the first embodiment shown in FIG. 7 are constructed by narrow linear cuts 17A and 18A.

It is clear that in this embodiment as well, the notch 18A solves the problems of conventional envelopes.

Note that the triangular cutout portion 30 in FIG. 9 has no particular relation to the effects of the present invention.

FIG. 11 shows an example of the fabrication of an envelope substantially the same as the envelope of the second embodiment shown in FIG. 10, but laterally arranged in a continuous form.

Note that the same or similar symbols refer to the same parts as in the above example, so the explanation will be omitted.

The embodiments described above can be modified in design without departing from the gist of the present invention.

For example, in the example shown in FIG. 8, the slip 27 may extend beyond the line glue 25A to completely cover the slip 28.

In this case, regarding line glue 25, slip paper piece 2
Another separable piece of paper will be added on the opposite side of 7.

As described above, according to the present invention, in an envelope having paper pieces that are connected to the opening of the envelope through the separation perforations,
It is possible to prevent the adhesive portions at both ends of the opening from peeling off, which is likely to occur when separating the paper pieces and widening the opening, thereby making it easier to widen the opening.
