Reciprocating envelope technical field

The present invention relates to a reciprocating envelope in which one envelope can be used not only as an outgoing credit but also as a reply envelope. Background art

Conventionally, for postcards, return postcards have been used together with outgoing credits (round-trip postcards), but for envelopes (or postcards) with enclosed contents, such round-trip envelopes exist. Did not. Therefore, when replying, it is usual to enclose a reply envelope.However, this requires two envelopes, increases the weight of the contents, and increases postage. It has a problem of becoming dull.

Therefore, Japanese Utility Model Laid-Open No. 6-59232 states that the opening tongue for closing the opening by folding it back is made longer, and gluing portions are formed at the top and bottom through the center cutting line. A disclosed reciprocating envelope is disclosed. When the sender uses the reciprocating envelope, the adhesive is applied to the upper gluing portion to seal the opening tongue and then sent out (posted). On the other hand, the recipient uses the reciprocating envelope. When it is received, cut it at the cutting line at the center of the opening tongue, apply adhesive to the lower glued part, and partially cut the opening tongue via adhesive. Seal.

In recent years, envelopes that can be opened without using cutting tools such as scissors have been widely used. Some typical envelopes are perforated to facilitate opening. Further, a double-sided tape is adhered near the opening, and the release paper is peeled off, and a material which can be sealed without using an adhesive such as glue has been widely used. In addition, the applicant of the present application has already applied for an envelope which can be easily and securely opened without using a cutting tool such as scissors by a method other than perforation. (Japanese Patent Application No. 2000-0—266 867, PCT / JP01 / 07705).

However, the reciprocating envelope disclosed in Japanese Utility Model Application Laid-Open No. 6-59232 is required only to insert scissors or the like into the cut line, and the person who received the reciprocating envelope (the recipient of the outbound communication) opened the envelope. If the tongue is cut from the base with scissors, it cannot be used as a reciprocating envelope anymore.

Also, when this round-trip envelope is used for reply, the destination address for outgoing credit and the destination address for reply are written on the same envelope, but if both are listed, there is the inconvenience that one of them is not clear. A seal indicating the destination must be enclosed (see the description of Japanese Utility Model Application Laid-Open No. 6-59232 mentioned above). Similarly, in the above-mentioned round-trip envelope, if it is used as an envelope for outgoing credit, it will be marked with a post office approval or postmark, and if you use this round-trip envelope with the post office approval, it will be used for reply. However, the post office approval is given again, but if the previous post office approval or postmark remains, it is unknown whether or not it was used.

Therefore, an object of the present invention is to provide a reciprocating envelope that can be used not only as an outgoing credit but also as a reply envelope, and can be opened without using scissors, etc., and used as a reply envelope. Another object of the present invention is to provide a reciprocating envelope that does not confuse the address, name or name of the reply and the reply of the post office.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

(First Embodiment)

The present embodiment is a reciprocating envelope F1 in which a paper-made horizontally long envelope F1 is provided with an opening tongue 5 in the longitudinal direction, as shown in FIGS. Fig. 1 and Fig. 2 are diagrams as seen from the front side of the reciprocating envelope F1.

The reciprocating envelope F1 of the present embodiment has a front sheet 1b constituting the front side of the envelope and a back sheet 1a constituting the back side of the envelope, and the inside of the front sheet 1b and the back sheet 1a is directed upward. It has a bag shape having an opening 4, and an opening tongue 5 that is folded over the back sheet 1a to close the opening 4 is provided (Figl (a)). The reciprocating envelope Fl is opened, and after the contents N are inserted from the upper opening 4, the opening tongue 5 is folded back to the outside of the front sheet 1 b and the front sheet 1 The opening 4 is closed by being connected to b with an adhesive, and the outgoing credit is sealed (FIG 1 (b)). When replying, the opening tongue 5 is inserted into the opening 4 after the connection between the opening tongue 5 and the front sheet 1b is released and the upper opening 4 is opened. 2 (a)) The front side sheet 1 b is connected with an adhesive to close the opening 4, and the reply is sealed (FIG. 2 (b)). Since the length L1 of the opening tongue 5 is shorter than the length L2 of the front sheet 1b, insert the opening tongue 5 into the opening 4 while the envelope F1 remains in a bag shape. It is not necessary to peel off the adhesive between the front sheet 1b and the back sheet 1a in order to insert the tongue piece 5 for opening, and to unfold it.

A stripped portion 2 is formed along the opening 4 in which the contents N of the reciprocating envelope F1 are put. The part 2 that has been subjected to the peeling treatment facilitates the adhesion and peeling of the opening tongue 5, and the position of the front sheet 1 b that is hidden by the folded opening tongue 5 (for opening in the case of the outbound credit). The tongue piece 5 and the front sheet 1b are formed in a belt-like shape below the opening 4 where the opening tongue piece 5 is folded back, that is, the opening side tongue piece 5 in the portion where the tongue piece 5 is in contact with the front sheet 1b. When the opening tongue piece 5 is folded back, the part 2 subjected to the peeling process is folded back (the lower end when the opening tongue piece 5 is folded back, also referred to as the outer peripheral end). It is formed to be wider than 5c. The part 2 that has been subjected to the above-mentioned peeling treatment is formed of a material having a property capable of being peeled off from the adhesive, and is specifically applied by printing with ink. When the agent is applied, a temporary adhesive state is obtained in which the adhesive force is lower than that of the paper portion of an envelope made of paper or the like. In addition, if the portion 2 that has been subjected to the peeling treatment with ink is formed so as to protrude from the outer periphery of the tongue piece 5 to be sealed, the tongue piece 5 becomes easy to peel off, and the tongue piece 5 is opened. Even if the adhesive applied to the side spreads, the opening tongue 5 can be easily peeled off.Furthermore, water drops such as rainwater hardly adhere to the outer peripheral end of the opening tongue 5 to be bonded. The outer peripheral end of the opening tongue piece 5 is also prevented from being weakened by water droplets or the like. In addition, one end of the opening tongue piece 5 at the opening position Has the word OPEN as its marker. That is, in the present embodiment, the opening tongue piece 5 is opened from the portion (knob portion) T of the OPEN character on the right side in the figure.

The part 2 that has been subjected to the peeling treatment is applied by printing, but it is a normal printing that applies ink (ink) to the plate surface of the printing plate and transfers it to paper etc., and is not special . That is, in addition to offset printing, screen printing, letterpress printing, and flexographic printing, printing by an ink jet printing device or a laser printer, which has become very popular in recent years, may be used. The part 2 subjected to the peeling treatment of the present embodiment is directly printed on the back sheet 1b by solid printing, but is printed in a band or sheet separately from the reciprocating envelope F1. The back sheet 1b may be adhered with an adhesive or a double-sided tape R. Also, as shown in FIG. 3, a portion 2 a that has been subjected to the ink-peeling treatment and a portion 2 b that has not been subjected to the ink-peeling treatment have formed portions where the ink is not applied and the envelope paper surface remains unchanged. Is also good. Fig. 3 shows an example in which a portion 2b, which is not subjected to the peeling treatment, is formed as a scattered portion in a portion 2a, which has been subjected to the solid peeling treatment, but a portion in which the peeling treatment is not performed is subjected to the peeling treatment. The applied portion may be formed in a scattered dot shape, and the latter is particularly effective when an adhesive is used as an adhesive. Printing inks (inks) are ordinary inks made by kneading pigments with oil or resin. That is, any ordinary ink used in the above printing may be used. Ink materials suitable for being subjected to a peeling treatment with ink to form a temporary adhesive state include styrene resin, polycarbonate, acrylic resin, epoxy resin and the like. Further, in order to perform the best peeling treatment, the respective raw materials may be mixed with each other, or a normal ink may be mixed. Further, a so-called release agent may be applied on the print, or the ink may be mixed with a release agent for printing. Solid printing (the part where the printed material is completely covered with ink; in halftone printing, the printing surface printed with 100% halftone dots) is subjected to release treatment with ink The part 2a and the part 2b that is not subjected to the peeling process, that is, the part where the ink is not applied and the envelope paper surface is intact, can be printed at the same time. In addition, the part 2 of the envelope body that has been subjected to the peeling process is printed, but this printing only needs to be performed simultaneously with the printing of the postal number column and post office approval, etc., which requires a special process. Printed without Further, in the present embodiment, the portion 2a subjected to the peeling treatment with the ink is applied by one or two times printing with one color. The printing color is not limited, and printing with a transparent ink such as a medium may be used. In addition, the postal code field and the address, address, address, name and name of the destination (for both sending and receiving credits) and the post office approval are printed in dark ink (for example, black) and transparent. Printing with a special ink and printing so that the reply address, name or name, or post office approval is reflected, or printing the above address etc. on the peeling print The address and the like may be displayed, and in this case, even if the opening tongue piece 5 is peeled off, printing can be performed so that the address, name or name, or post office approval is retained. It is also possible to implement that the portion 2a subjected to the peeling treatment by the ink is halftone printing, and the portion 2b not subjected to the peeling treatment is two types of halftone printing (first example). See Example 1 of the embodiment). In halftone printing, the amount of ink increases when the percentage of halftone dots is about 60% or more (it can be close to solid printing), and when the percentage of halftone dots is about 40% or less, the amount of ink increases. The amount is reduced, and it is possible to adhere to the opening tongue via an adhesive such as glue. Furthermore, the portion 2 subjected to the peeling process can be implemented by one type of halftone printing having the same halftone dot ratio. Halftone dot printing is the ability to express halftones by using halftone dots to express the density of the dots. 2a and “parts not subjected to peeling treatment” 2b can be divided, and the temporary adhesion state and the actual adhesion state can be separated, and gradation (gradual transition from a dark part to a light part, Or the opposite situation). It is possible to use a synthetic resin agent or varnish that can be peeled off in the same manner as the components contained in the ink, depending on the implementation. In recent years, inks containing vegetable ingredients such as soy inks (called eco-inks because they are environmentally friendly) may be used. No. In addition, as the portion 2 subjected to the peeling treatment, printing with ink, heat sealing, strong pressure bonding, or the like can be used. Heat sealing is already used on postcards as a means of maintaining confidentiality, but adhesive types and types that seal by thermocompression bonding are known. It is also possible to use a double-sided tape or sheet that has been subjected to heat sealing or strong pressure bonding and is peelable. In each case, a sheet-like or tape-like material such as a peelable seal film is used. The adhesive type is composed of a multilayer structure such as a pressure-sensitive adhesive layer, a transparent ink layer, a PE film layer, an adhesive layer, and a colored synthetic resin layer, such as for postcards. It also has the advantage of increasing

An application area 3 for applying an adhesive such as glue is formed in a band shape on the back side (inside) 5b of the envelope of the opening tongue 5, that is, the inside 5b when the opening tongue 5 is folded. Have been. The adhesive applied to the application area 3 may be an adhesive such as ordinary glue, and particularly when large quantities are used, arabia glue or ad hair glue is used. Adhesive glue ゃ double-sided tape R, or hot melt adhesive lj (a kind of simple instant adhesive that uses heat) (characteristics become liquid when heated, shows fluidity, and returns to the original solid when cooled) May be applied. The application region 3 is formed as a guide when applying an adhesive such as glue. The method of application may be applied to the entire surface of the application area 3 or may be applied at predetermined intervals or in scattered spots, regardless of the application method.

Here, as shown in FIG. 3, a double-sided tape R may be provided on an opening tongue piece 5 inserted into the opening 4. That is, when the tongue piece 5 for opening is inserted into the opening 4 when the content N below the opening 4 is inserted into the opening 4, that is, when opening the reply, the front sheet 1 b is opened. The double-sided tape R is disposed on the side of the front sheet 1b in the portion where the tongue piece 5 contacts. This double-sided tape R is used as an adhesive for sealing the opening 4 for replying, so that the adhesive such as glue is not required by disposing the double-sided tape R. Have been. Next, how to actually use the envelope F1 of the present embodiment will be described. First, when using as an outbound credit, the contents N are sealed from the opening 4 (Fig. 1 (a)), and the opening tongue 5 is folded out of the front sheet 1b to perform the above-described peeling treatment. It is superimposed on the applied part 2 with an adhesive (FIG. 1 (b)). The adhesive may be applied to the application area 3 and bonded to the part 2 that has been subjected to the release processing, or may be directly applied to the part 2 that has been subjected to the release processing. Note that a double-sided tape R may be used at these corresponding positions. Then, the opening tongue piece 5 and the part 2 subjected to the peeling treatment are in a temporary bonded state in which the part can be peeled. In other words, in the portion 2 where the ink has been subjected to the peeling treatment, the adhesive is in a temporary bonded state where the adhesive can be peeled off in relation to the components of the printing ink such as oil and resin.

The person who receives this reciprocating envelope (envelope) F1 opens the tongue piece 5 for opening by holding the knob T between the fingers. In other words, if the tab T of the opening tongue 5 is opened by sandwiching it with a finger, the peeled portion 2 can be peeled off from the adhesive. The applied portion 2 is easily peeled off, the connection between the opening tongue piece 5 and the front sheet 1b is released, and the reciprocating envelope F1 is opened (FIG 1 (a)). Then, the contents N are taken out from the opening 4 in the opened state.

When using the envelope again, such as when replying to the sender of the original credit, insert the peeled-off tongue piece 5 into the opening 4 as shown in Fig 2 (a) (b) (F ig 2 (a)), and the opening tongue 5 is adhered to the inner surface of the opening 4 (the front side content N side of the reciprocating envelope), that is, the inner surface of the front side sheet 1 b (F ig 2 (b)) ). For bonding, an adhesive such as glue may be used. In addition, as shown in FIG. 3, in the return seal, of the joining surface between the opening tongue piece 5 inserted into the opening 4 and the front sheet 1b, the front sheet 1b side or the opening tongue piece. If the double-sided tape R is provided on the side of 5, the release paper Rc of the double-sided tape R is peeled off, and the opening tongue piece 5 to be inserted and the front side sheet 1b are joined together. The reply envelope can be sealed without the need to apply a seal. Therefore, if one reciprocating envelope F 1 of the present embodiment is used, It can be opened without using cutting tools such as scissors, etc.On the other hand, when used as a reply envelope, it can be used as a reply envelope without using glue or other adhesive, or as a re-sealable envelope. Will be available. Note that, instead of the double-sided tape R, a sheet provided with a peelable release paper on an adhesive may be used.

Here, the reciprocating envelope F 1 of the present embodiment has an outer side of the opening tongue 5 (the side opposite to the side on which the opening tongue is folded) 5 a, that is, an opening tongue in the sealed state for return. In the position hidden in the front sheet 1b of 5, the destination of the outgoing credit, specifically, the name or address of the recipient, the display of the address, the barcode and "payment after payment", the post office approval, the receiver of the charge There is a column 9B where payment is indicated. On the other hand, the side of the reciprocating envelope F 1 on the side of the opening 4, that is, the position of the front sheet 1 b hidden by the opening tongue 5 (the opening tongue 5 is folded) Below the opening 4), the address (name or name, address or place of residence) of the recipient (recipient) when replying, the display of a "round-trip envelope", post office approval, and charge collection There is a column 9A for displaying a person payment and a bar code. A stamp may be affixed to column 9A where "Payee payment" is displayed. In this manner, the postmarks of the post office are also set to the positions indicated by the reference numerals 9A and 9B. These need only be done at the same time as printing the envelope design. In this embodiment, in each case, only the normal front side sea i b is used. In the following, in the present specification, the columns where the post office approval such as the address or residence, name, name, barcode, and `` payee for payment '' etc. are displayed for the reply are printed. In the column 9 A, the address, name, name, per code printed as outgoing credit, etc., and the approval of the post office, such as "payee payment", "payment after payment", "payment separately", etc. are displayed. This column will be described as outgoing credit column 9B.

When sealing the outgoing credit, the opening tongue 5 is folded back to the outside of the front sheet 1b, and the address and office approval etc. of the outgoing credit column 9B are recognized, and at the same time, the reply column 9A is The address and approval of the station are hidden by the tongue piece 5 for opening. On the other hand, when replying, the opening tongue 5 is inserted into the opening 4 and sealed. (Address or residence, name or name) and office approval etc. will be hidden on the front sheet 1b, and the address (address or residence, name or name) and office approval etc. in the reply column 9A will be on the front. Will appear. Therefore, the destination (address or place of residence, name or name) and the approval of the bureau will not be confused for outgoing credit and reply. The columns 9A and 9B with the label “Payee payer,” are subjected to heat sealing, strong crimping, etc. already used for postcards as a means of maintaining confidentiality. Is also good. In addition, a peelable double-sided tape or a sheet-like material that has been subjected to such processing is provided in only one of the reply column 9A and the outgoing credit column 9B, and is described in the other column. Items to be performed (addresses, etc.) may be described at other positions on the front sheet 1b or on the back sheet 1a.

(Other Example 1 of First Embodiment)

In the present embodiment, as shown in Fig 4 (a) and (b), a horizontally long reciprocating envelope F1a made of paper, and a reciprocating envelope F1a provided with an opening tongue 5 in the longitudinal direction thereof. The basic configuration is the same as the reciprocating envelope F 1 of the first embodiment, but the part 2 of the reciprocating envelope F 2 that has been subjected to the peeling process is the same as that of the first embodiment. In the seal of the outgoing credit, the side 5b of the opening tongue 5 in the portion where the opening tongue 5 and the front sheet lb are in contact with each other, and the back side of the envelope in the opening tongue 5 (that is, the opening The surface 5b, which becomes the inside when the tongue piece 5 is folded back, is provided on the surface (5b) to which the adhesive of the ordinary envelope is applied. Therefore, in the present embodiment, the force for directly applying an adhesive such as glue on the part 2 on which the peeling treatment has been performed \ glue is provided at a position corresponding to the part 2 on which the peeling treatment has been performed on the front sheet 1b. An adhesive such as is applied to seal outbound credit. Note that a double-sided tape may be used instead of an adhesive such as glue (see FIG. 3). In the reciprocating envelope F1a of this embodiment, the part 2 of the reciprocating envelope F1a that has been subjected to the peeling treatment is printed with a part 2a that has been subjected to the peeling treatment with ink and a part 2b that has not been subjected to the peeling treatment. The part 2 a of the envelope F 1 a subjected to the peeling treatment of the present embodiment is not subjected to the circular peeling treatment while the part 2 a subjected to the peeling treatment with the ink is solid printing. Part 2b, where no ink was applied and the envelope paper was left intact Are partially formed at predetermined intervals (equal intervals). It is also possible to form a circular shape into an oblique elliptical shape so that smooth peeling can be performed according to the opening direction of the opening tongue piece 5, or it is possible to scatter this circular shape or elliptical shape etc. It is. The shape of the portion 2b that is not subjected to the peeling treatment may be a triangular shape, a rhombic shape, or the like, in addition to the embodiments described later, and various shapes are conceivable. In addition, the portion 2b not subjected to the peeling process is formed with a smaller area than the portion 2a subjected to the peeling process with the ink. Thereby, when opening the opening tongue 5, the portion 2b that is not subjected to the peeling treatment is removed with a light force (the opening tongue 5 can be peeled from the front sheet 1b). . The portion 2 that has been subjected to such a peeling treatment is formed so as to be wider than a bonding area (application area) of an adhesive such as glue of the opening tongue 5 and the front sheet 1b. In particular, peeling by picking from the knob τ is easily performed. Therefore, in the part 2a where the adhesive and the peeling treatment are applied, the part 2a where the peeling treatment is performed with the ink is in a temporary bonding state where the peeling is possible, and in the part 2b where the peeling treatment is not performed, The glue is actually glued. In other words, in the area 2a subjected to the peeling treatment with the ink, the adhesive becomes a temporary adhesive state in which the adhesive can be peeled off in relation to the components of the printing ink such as oil and resin, and the area 2b not subjected to the peeling treatment Then, the actual bonding state between the paper on the front side sheet 1b of the paper envelope and the paper on the inner surface 5b of the opening tongue 5 is obtained. Therefore, as compared with the reciprocating envelope F1 of the first embodiment having the solid-treated peeling portion 2 without the portion 2b not subjected to the peeling treatment, it is (partially) opened from the appearance. The tongue piece 5 is firmly adhered.

(Another example 2 of the first embodiment)

In this embodiment, as shown in FIG. 5 (a) and (b), a horizontally long reciprocating envelope F 1 b made of paper, and a reciprocating envelope F 1 b provided with an opening tongue 5 in the longitudinal direction. The basic configuration is the same as the reciprocating envelope F1 of the first embodiment, but a pair of left and right cuts 8A, 8A are formed from the opening 4 side of the reciprocating envelope F1b to the lower side. B is formed. That is, the left and right cuts 8 A, 8 B The front sheet 1b and the back sheet 1a are separated from each other to form a bent portion 6, and the back sheet is folded back in a state in which the connection between the opening tongue 5 and the front sheet 1b is released. It can be separated from sheet 1a. As described above, the configuration in which the bent portion 6 comes into contact with and separates from the back sheet 1a is formed by forming perforations instead of the cuts 8A and 8B, or by using an outer peripheral tongue piece provided on the outer periphery of the back sheet 1a described later. 13 and 14 may be close to the front sheet (envelope surface) 1 b and the opening 4, and only the portions may not be bonded. Regarding the sealing of the envelope (that is, the connection between the opening tongue piece 5 and the front sheet 1b), the application area is clearly indicated at the position where the double-sided tape R is disposed as a guide for applying the adhesive. It may be sealed with an adhesive such as glue. The perforation M a1 is formed on the opening tongue piece 5 above the joining position with an adhesive or the like.

Therefore, the person who has received the entrusted envelope can tear open the perforation Ma 1 and open the envelope F 1 b easily and without damage. On the other hand, when the envelope is used again, such as when replying to the sender of the foreign credit (including when the envelope is used as an envelope to another person), insert the peeled-off tongue piece 5 into the opening 4. However, the bent portion 6 formed on the upper side of the front side sheet 1b by the cuts 8A and 8B and perforations is provided so as to be able to contact and separate from the back side sheet 1a and the outer peripheral tongue pieces 13 and 14. The bent portion 6 is bent in a direction away from the back sheet 1 a and the outer tongue pieces 13, 14, and the opening tongue piece 5 is inserted into the opening 4 while expanding the opening 4. The opening 4 can be sealed by connecting the inserted opening tongue 5 to the front sheet 1b via an adhesive or a double-sided tape R or the like. That is, the cuts 8A and 8B make it easier to insert the opening tongue piece 5 into the opening 4 and prevent the opening 4 from causing damage such as cutting from the opening 4 at the time of insertion. You. Further, when the opening tongue 5 is inserted from the opening 4 and is attached to the front side sheet 1b in the sealed state of outbound credit, even if the perforation Ma2 is formed in the bent portion 6, good. Also, along the upper part of the part 2 that has been subjected to the peeling treatment, Perforations Ma 2 may be formed. When the perforation Ma 2 is peeled off the opening tongue piece 5 from the peeled portion 2, the peeling is not performed properly.

(The surface is peeled off thinly.) This is to prevent the column 9 A, which is printed on the outer surface of the bending portion 6, such as “Payee payer”, from being peeled off. Therefore, when a person who has received the envelope F 1 b removes the opening tongue 5 from the part 2 that has been subjected to the peeling treatment when the end of the opening tongue 5 is sandwiched with a finger and opened. Furthermore, even if this peeling is not successful, it is possible to prevent the column 9A on the outer surface of the folding tongue piece 6 on which an indication such as "payee receiving person" is given from being peeled.

(Other Example 3 of the present embodiment)

Here, as another example 3 of the present embodiment, applying the example 2 and applying a peeling treatment to the cuts 8A and 8B as shown in FIGS. 6 (a) and (b). It is also possible to provide 10 A, 1 OB on the left and right. The reciprocating envelope F 1 c is formed by laminating the front sheet (envelope front surface) 1 b and the back sheet 1 a via outer tongue pieces 13 and 14 provided on the left and right sides of the back sheet 1 a. Above the tongue pieces 13 and 14, peeled parts 10 A and 10 B are provided, and the left and right sides of the bent part 6 and the left and right upper parts of the front side seat ib are left and right peeled parts They are joined via 10 A and 10 B. Peripheral tongue pieces 13 and 14 formed on the left and right sides of the back sheet 1 a are bent inward, and the front sheet 1 b is superimposed on it

(Also called “force mass tension”) and a type in which the outer peripheral tongue pieces 13 and 14 are bent and overlapped on the left and right sides of the front sheet 1b (also called “reverse force mass tension”). The configuration in which the tongue pieces 13, 14 and the front sheet 1b are separated from each other to separate the front sheet ib and the back sheet 1a to form the bent portion 6 is applied to the former force mass tensioning, A peeling treatment is applied to the overlapped portion away from the back sheet 1a so that the overlapping portion can be peeled off, and the folding tongue piece 6 can be folded back. The parts 1 OA and 10 B that have been subjected to the peeling treatment are formed in the same manner as the parts 2 that have been subjected to the peeling treatment. Can be applied. In addition, there is a counter-force mass tension, a middle paste where the lamination is in the center and there is no outer peripheral tongue on the left or right, or a left lateral paste that is laminated on either the left or right side and has no outer peripheral tongue on the right. In the case of horizontal bonding, etc., a perforation may be provided at a predetermined width at the left and right upper part of the boundary between the front sheet 1b and the back sheet 1a when forming the bent portion 6, or the left and right upper part of the boundary To separate the front sheet 1b and the back sheet 1a by a predetermined width, apply peeling treatment 10A, 10B to the left and right sides of the bent part 6 or the left and right upper parts of the back sheet 1b, and bend The part 6 and the back sheet 1b may be bonded with an adhesive via the parts 1 OA and 1 OB subjected to the peeling treatment.

Therefore, in this embodiment, when the envelope is used again, such as when replying to the sender of the outgoing credit, the peeled-off opening tongue 5 is inserted into the opening 4 (although it is woven into the inside of the main body). In addition, the bent portion 6 which can be separated from and separated from the outer tongue pieces 13 and 14 by the stripped portions 10 A and 10 B is provided. The opening tongue piece 5 can be easily inserted into the opening 4 by peeling it off from the backing sheet 14 and bending it away from the backside sheet 1 a to widen the opening 4. Then, the double-sided tape-sized release paper R c (see FIG. 3) that appears by bending the bent portion 5 is peeled off to expose the adhesive, and the folded-back surface of the folded tongue 5 (opened) is opened. If the tongue piece 5 is folded back, that is, if the unsealing tongue piece 5 is bonded to the outer surface 5a when it is folded, a reply seal is obtained.

FIG. 7 (a) is an expanded view of the envelope F1d of the present embodiment, and FIG. 7 (b) is a rear view of the envelope F1d. The present embodiment is a reciprocating envelope F 1d in which a paper-made horizontally long envelope F 1 is provided with an opening tongue 5 in the longitudinal direction, and the basic configuration is the same as that of the first embodiment. Same as the reciprocating envelope F 1, but the outer peripheral tongue pieces 13 and 14 are not provided on the left and right sides of the back sheet 1 a, and the outer peripheral tongue pieces 13 and 14 are provided on the left and right sides of the front sheet 1 b Have been. The reciprocating envelope F 1 d is provided on the left and right sides of the front side sea ib. The outer peripheral tongues 13 and 14 are bent, and the outer peripheral tongues 13 and 14 are arranged and bonded to the outer surface of the back sheet 1a. 14 has appeared. Therefore, it is generally recognized that the side on which the outer peripheral tongue appears is the back side of the envelope, and the address or post office approval or stamp is displayed on the front side of the envelope. On the other hand, it can be recognized that the side of the back sheet 1a on which the outer peripheral tongue pieces 13 and 14 appear is the back side of the envelope, and the opposite side is the front side of the envelope. The reciprocating envelope Fid is located at a position hidden by the opening tongue in the front side sheet in the outgoing credit sealed state, or in a front side sheet of the opening tongue in the reply closed state (such as the hidden position). In addition, the address and the office approval are printed at a different position from the general envelope, but by using the outer tongue pieces 13 and 14 as clues, the back and front sides of the reciprocating envelope Fld can be recognized and distinguished immediately. The outer tongue is provided not only on the left and right sides of the front sheet lb but also below the front sheet lb, and the outer tongue is disposed outside the back sheet 1a. By sticking together, the outer peripheral tongue piece is recognized not only on the left and right sides of the back sheet 1a but also below the back sheet 1a, so that the back sheet 1a may be more strongly impressed.

There is no possibility that the tongue 5 for opening is damaged at the time of opening due to an error in the determination or the amount of application, and becomes unusable at the time of reply.

(Fifth embodiment)

The reciprocating envelope F5 of the present embodiment is a reciprocating envelope F5 provided with a perforation M for opening the envelope. The reciprocating envelope F5 of the present embodiment is a fig 17 (a) (b) As shown in Fig. 18 and Fig. 18 (a) and (b), a vertically long reciprocating envelope F5 made of paper, which has basically the same configuration as the reciprocating envelope F1e of Example 5 of the first embodiment. However, the only difference is that the portion 2 subjected to the peeling treatment is not provided, and a perforation M for cutting is formed in the longitudinal direction of the tongue piece 5 for opening. The perforation M is designed to facilitate the insertion of the opening tongue 5 into the opening 4 of the envelope F5 (to facilitate folding into the inside of the main body) and to reduce the length of the opening tongue 5. It is formed to make it shorter. In addition, this perforation M is cut at the time of opening to be opened. Therefore, if the opening tongue piece 5 is long, the length of the opening tongue piece 5 is adjusted along the line M after the above-mentioned opening tongue piece 5 is peeled off. Fig 17 (b)). In the sealing of foreign credit, an adhesive is applied only to a portion below the perforation M when the opening tongue piece 5 is folded back, and is adhered to the front side seam ib and connected. A double-sided tape with release paper may be pasted only on the lower side of the perforation M in advance, and the release paper may be peeled off to seal the incoming credit. When the opening tongue piece 5 is cut along the perforation M, the cut piece 5 f of the opening tongue piece 5 remains in a state of being adhered to the front sheet 1 b (FIG. 8 (a) ( b)). The method of using this reciprocating envelope F5 is shown in order of the operation when the recipient of the envelope of FIG. 17 (a) and FIG. Create a reply envelope F5 in the order of a) and Figl 8 (b). That is, the recipient who has received the outgoing credit envelope opens the opening 4 by cutting the opening tongue 5 along the perforation M (FIG. 17 (b)). The folding of the tongue piece 5 for opening the return letter and opening the reply seal is the same as that of the envelope F1 of the first embodiment.

Fig 19 (a) is a front view of a reciprocating envelope F5a of another example of the embodiment, (b) is a view showing an opened state, and Fig 20 is a sealed state for reply. FIG. The reciprocating envelope F5a is almost the same as the reciprocating envelope F4 of the fourth embodiment, except that the tongue 7 for sealing is attached to the outside of the front sheet 1b in the outgoing seal. The sealing tongue 5 is provided with a perforation M. At the top right of the front sheet 1b, destinations for outgoing credits, customer barcodes for sorting, etc. are described.

The recipient who has received the envelope of the outgoing credit picks up the upper end 5c of the opening tongue 5 and the upper end of the front sheet 1b, and peels off the opening tongue 5 and the front sheet 1b according to the mark of the arrow. As a result, the perforation M is torn and the first opening 4a is opened (FIG. 19 (b)). When the opening tongue 5 is pulled out from the first opening 4a and attached to the outer surface of the front sheet 1b to seal the reply (FIG. 20), the opening tongue 5 causes The “payment after payment” seal and a part of the customer barcode are hidden, and the address of the outgoing credit is hidden with the name “sama” of the name, and becomes the address for the reply, and the reply for the opening tongue piece 5 A reply column 9A appears in which the destination address and the customer barcode for sorting etc. are described. The post office sorting machine does not read outgoing customer barcodes, which are partially hidden, but reads the replying customer barcodes, which appear as a whole, to sort.

(Sixth embodiment)

Fig. 21 (a) (b) and Fig. 22 (a) (b) are front views of the reciprocating envelope F6 of the embodiment, and Fig. 23 is an opening tongue piece 5 and a front sheet. FIG. 5 is a view showing a state where the connection with 1b is released and a first opening 4a is opened. The reciprocating envelope F 6 of the present embodiment is a vertically long reciprocating envelope F 6 made of paper, and has substantially the same configuration as the reciprocating envelope F 4 of the fourth embodiment. No peeled portion 2 is provided, and the tongue piece 5 for opening and the front sheet 1b are adhered by an adhesive P such as glue arranged in a scattered manner. The adhesive P is formed on the side of the opening tongue 5 in the portion where the opening tongue 5 and the front sheet 1b are in contact with each other in the sealed state, and when folded back, the lower side is formed. It is applied in a state where the points are arranged in a straight line along the end 5d. The adhesive P can be evenly scattered. The size of each point of the adhesive P (that is, the applied amount of each point of the adhesive P) is arbitrary. It is necessary to adjust the adhesive strength so that it can be peeled off when it is pulled apart from the front sheet 1b.

Since the tongue for opening 5 and the front sheet 1b are glued with the scattered adhesive P, the adhesive strength is weak, and the recipient who has received the envelope received the front sheet 1b and the tongue 5 for opening. The tongue piece 5 for opening is peeled off from the front sheet 1 in a clean state when it is pulled so as to peel off.

As shown in FIG. 24, the position corresponding to the adhesive P in the outward seal, that is, the portion where the opening tongue 5 and the front sheet 1b are in contact with each other, is located on the side of the front sheet 1b. A portion 2 that has been subjected to a peeling treatment may be provided. Since the scattered adhesive P is adhered to the front sheet 1b via the peeled portion 2, the adhesive P is more easily peeled off from the peeled portion 2, and when opened. The opening tongue 5 and the front sheet 1b are less likely to break. The scattering adhesive P can be applied to any of the first to fourth embodiments.

(Seventh embodiment)

Fig. 25 and Fig. 26 are front views of the reciprocating envelope F7 of the seventh embodiment, and Fig. 27 is a view of the reciprocating envelope F7 of the present embodiment in an unfolded state. Fig. 28 shows the usage state of the reciprocating envelope F7 of the present embodiment. The reciprocating envelope F7 of the present embodiment is a horizontally long envelope made of paper, and the reciprocating envelope F1 of the first embodiment has the information description sheet 11 provided thereon.

Above the front sheet 1b of the reciprocating envelope F7 (that is, on the side of the opening 4), an information sheet 11 on which information is written is provided continuously and integrally with the front sheet 1b. . The information sheet 11 has several folding positions t1, t2, and t3 for folding, and is folded several times. With the information-recording surface 11a inside, the folding position tl, At times t 2 and t 3, the storage space S is folded downward and stored in the storage space S (FIG. 27 (a) (b)).

The information sheet 11 is slightly narrower than the width w1 of the reciprocating envelope F7. It is shorter than the vertical width w2 of the outer shape of the reciprocating envelope F7, and has a horizontally long rectangular shape as a whole. The information sheet 11 has several folding positions for folding and is folded several times, but has a rectangular shape in the unfolded state. Further, the information description sheet 11 has information written on at least an inner surface 11a in a folded state described later. The information described on the information sheet 11 includes the contents of the application form for reply to card enrollment sent from the company to the individual, direct mail, grade report, invoice, tax payment form from the tax office, and letters. Content. That is, the information sheet 11 is a portion corresponding to the contents of a letter or the like conventionally prepared separately from the envelope.

In the information sheet 11, folding positions t 1, t 2, and t 3 are set at predetermined intervals in the order from the front sheet 1 b at positions where the information sheet 11 is substantially equally divided into three. The folding positions t1, t2, and t3 are parallel to the boundary between the front sheet 1b and the information sheet 11.

The information sheet 11 is folded downward so that a part 11b of the information sheet 11 protrudes. That is, the folding position t1 adjacent to the front sheet 1b is a position at a predetermined interval from the boundary between the front sheet ib and the information sheet 11 to the information sheet 11 side. In the reciprocating envelope F7 of the present embodiment, since the information sheet 11 is narrower than the front sheet 1b, the protruding portions 11b of the information sheet 11 are located on the left and right sides of the front sheet 1b. Appears only near the center without appearing.However, if the width of the front sheet ib and the information sheet 11 are the same, the information sheet 11 extends over the entire left and right sides of the front sheet 1b. Projecting part 1 1 b Appears. Further, the height of the protruding portion 11b of the information writing sheet 11 is arbitrary, but it is desirable that the height should be such that the recipient can easily pick it with a finger.

The information sheet 11 is further folded in the storage space S at the folding positions t 2 and t 3 with the side 5 a that is the inner side in the folded state when folded at the folding position t 1 inside. . That is, the information sheet 11 is longer than the outer shape of the reciprocating envelope F7. The force that is long Since it is necessary to fit in the storage space S of the reciprocating envelope F 7 when folded, these two points in the storage space S are slightly smaller than the outer shape of the reciprocating envelope F 7 and have a rectangular shape. Are further folded and stored at the folding positions t 2 and t 3. In the present embodiment, folding is performed twice at the folding positions t 2 and t 3 in the storage space S, but the number of times of folding in the storage space S may be more or less. It is optional to write information on the outer surface 11c in the folded state of the information description sheet 11 if necessary, but from the viewpoint of confidentiality of the present invention, the information description sheet 11 It is preferable to write information as much as possible on the inner surface 11a in the folded state. Information that needs to be kept confidential is described on the inside 11a of the information sheet 11, and information that does not need to be kept confidential is a separate letter such as a conventional letter. The contents can be inserted into the storage space S through the opening 4 and used, or the information sheet 11 can be placed on the outer surface 11 c of the information sheet 11 as shown below. Two perforations 12 a, 12 b are provided at positions overlapping each other in the folded state, and by cutting these two perforations 12 a, 12 b simultaneously, the perforations 12 A part 1 1b, which is a part protruding above a, 12b, can be cut off. Specifically, the information sheet 11 is provided on the information sheet 11 so that the part (the upper side of the perforation) 11b can be cut off from the reciprocating envelope F7. Part that protrudes by folding downward (part above the perforations) 1 1b With the ridge formed at the upper end of b (that is, the ridge corresponding to the folding position t1 adjacent to the front sheet 1b) sandwiched Two perforations 12a and 12b for simultaneous cutting are provided at positions where they are in contact with each other. One perforation 1 2a is formed at the boundary between the information sheet 11 and the front sheet 1b, and the other perforation 1 2b is one perforation on the side folded downward at the folding position t1. It is formed at a position in contact with the eye 12a. To see the information written on the inner surface 1 1a of the information sheet 11 of this reciprocating envelope F7, turn the opening tongue piece 5 adhered through the peeled part 2 After the reciprocating envelope F7 is opened, the part that protrudes from the upper side of the front sheet 1b is partly protruded by simultaneously cutting two overlapping perforations 12a and 12b while holding the lib. (A part above the perforation) 11 1b is cut off, and the information recording sheet 11 is separated from the front sheet lb (Fig. 28 (b)). Therefore, the recipient of the envelope can not only cut off the information sheet 11 without using a cutting tool such as a scissor knife, but also a part that protrudes (a part above the perforation). Since the perforations 12a and 12b can be cut by picking the lib with a finger, the separation work becomes easy. The state of the reciprocating envelope F7 from which the information sheet 11 has been cut off is the same as that of the reciprocating envelope F1 of the first embodiment.

The information recording sheet 11 is further folded in the storage space S with the inner surface 1 1a inside when folded downward at the folding position t1 where the information recording sheet 11 contacts the front sheet 1b. 2. Since the envelope is folded at t3, even if the envelope F7 is opened from the opening tongue piece 5, the information described on the inner surface 11a remains hidden. Therefore, the reciprocating envelope F7 of the present embodiment is provided with a portion subjected to a peeling treatment so that the tongue piece 5 for opening is easily peeled off. However, it is unlikely that information such as letters and application forms will be seen by others. Since the information sheet 11 is folded in the storage space S to be thick and the storage space S becomes full, the information sheet 11 is pulled out from the opening 4 by curving the sheet 11 without separating it. This makes it difficult to keep the information described on the information sheet 11 confidential. Further, even if the information sheet 11 is larger than the outer shape of the envelope F7, it can be stored in the storage space S by being further folded in the storage space S. Therefore, even when the size of the information sheet 11 increases due to a large amount of information to be recorded, the information description sheet 11 may be further folded in the storage space S as in the present embodiment. Other configurations are the same as those of the first embodiment. And duplicate explanations are omitted. Also, the sealing of outgoing credit and the sealing for reply are the same as in the first embodiment.

The information description sheet 11 can be provided on the reciprocating envelope of each example of the first embodiment or the reciprocating envelope of the second to sixth embodiments.

As described above, in the description of each embodiment, the case where the reply destination is the sender using the outgoing envelope is described. It is also possible to mail to a third party other than the sender using the credit envelope, that is, use it like a normal envelope. In addition, in the description of each embodiment, the description has been made using a paper envelope. However, the envelope is made of paper such as cardboard, thin paper used for ordinary envelopes, cardboard (cardboard) paper, and the like. Envelopes that have a window on which a transparent film is adhered on the front side, and that have the address and name printed on them can be used for a wide range of envelopes and other types of envelopes that can be recognized from the outside. It can be used. Furthermore, in the automatic encapsulation of contents performed when mailing a large number of sealed letters, not only when the contents are inserted through the opening 4 but also on either side of the outer peripheral tongue pieces 13, 14 or However, the present invention can also be applied to a case where automatic sealing is performed from an outer peripheral tongue piece opposite to the opening 4. As means for releasing the connection between the opening tongue piece 5 and the front sheet 1b, any of the perforation M, the scattered adhesive P, and the part 2 subjected to the peeling treatment is used. Is also good. Folded part 6, part of peeled part formed on bent part 6 that has been subjected to peeling 10 A, 10 B, columns for outgoing or replying to destinations 9 A, 9 B, outer peripheral tongues 13, 14 The information description sheet 11 can be applied in any combination. Industrial applicability

Therefore, according to the reciprocating envelope described in claims 1 or 3 of the present invention, when the envelope is used again, for example, by replying to the sender of the outgoing credit, the connection is released. By inserting the opened tongue piece into the opening and sealing the opening with an adhesive or the like, it becomes possible to use one envelope as a reply envelope.

According to the reciprocating envelope described in Claim 2 or Claim 4 of the present invention, when the envelope is used again, for example, by replying to the sender of the outgoing credit, the opened tongue piece whose connection has been released is used. By leaving the inside of the opening to the outside and sealing the opening with an adhesive or the like, one envelope can be used as a reply envelope without using cutting tools such as scissors. Will be possible.

According to the reciprocating envelope described in claim 3 or claim 4, in the case of outbound credit, the second opening different from the upper first opening closed by the opening tongue is sealed. This eliminates the need for strict positioning of the adhesive or the adhesive tape or the adjustment of the amount of the applied adhesive.

According to the reciprocating envelope according to claims 5 to 8 of the present invention, a cutting tool such as scissors can be used by a peeled portion, a perforated line, or a scattered adhesive. However, the connection between the opening tongue and the front sheet can be released to open the envelope, which facilitates the opening operation. When the recipient opens the reciprocating envelope when opening the reciprocating envelope, the opening tongue may be cut from the root or the opening tongue may be broken, making the opening tongue unusable when replying. Nothing happens.

According to the reciprocating envelope described in claims 9 or 10 of the present invention, when the opening tongue is pulled out from the opening or inserted into the opening, the bent portion is bent in a direction away from the front sheet. Thereby, the opening can be widened, and the work of pulling out and inserting the tongue for opening becomes easy. In addition, the folded portion and the back sheet are bonded to each other with an adhesive through the portion subjected to the peeling treatment, thereby preventing the folded portion from separating from the envelope body unless the bent portion is peeled from the front sheet. be able to.

According to the reciprocating envelope according to claim 11 of the present invention, when sealing for reply, if the release paper on the double-sided tape or the release paper on the adhesive is peeled off, the opening is sealed. Adhesion at the time of performing is possible, and it is possible to seal for reply without re-applying an adhesive such as glue.

According to the reciprocating envelopes of claims 12 to 15 of the present invention, when sending or returning, the tongue for opening is inserted into the opening or put out and sealed. Then, since the address for outgoing credit and the address for reply are hidden or appear, the confusion as to whether the address or name, the approval of the post office, etc. is for outgoing credit and reply is used as in the past. Can be prevented.

According to the reciprocating envelope according to claim 16 of the present invention, since the destination and the like are reflected on the part subjected to the peeling treatment, the destination and the like and the part subjected to the peeling treatment overlap. Also, the destination etc. can be recognized.

According to the reciprocating envelope described in claim 17 of the present invention, since the outer peripheral tongue appears on the outside of the back sheet, the side of the back sheet where the outer tongue appears on the back of the envelope is displayed to the envelope deliverer and the like. It can be recognized that the opposite side is the front side of the envelope. And even if the address or the office approval is printed at a position different from the general envelope, such as the outside surface of the opening tongue or the position hidden by the opening tongue on the front sheet, the outer tongue The presence and absence of a key can be used as a clue to distinguish and recognize the back side and front side of the envelope, making it possible to immediately find the destination, etc., and prevent overlooking the destination, etc.

According to the reciprocating envelope described in claim 18 or claim 19 of the present invention, even if the envelope is opened from one side of the opening tongue during delivery or the like, the envelope is described on the inner surface. Information is hidden and difficult to see. Therefore, even if the connection between the opening tongue and the front side sheet is easily released by the perforated or scattered adhesive, the information sheet that is the content of the envelope The information described in is likely to be kept confidential.
