Description

  The present invention is a technology that can be reused after the original purpose of use of a paper bag or a handbag, a mailing envelope for a written document or publication, an envelope containing a pamphlet, etc., when a product is purchased at a store or department store. A print, a predetermined separation line is formed on the inner surface of a paper container and a predetermined separation line is formed on the inner surface of the paper container, and the printed separation line is cut along the separation line. It is intended to be reused according to the printing formed on the inner surface of the paper container by cutting along with scissors.

  Conventionally, when a product is purchased at a store or a department store, it has been handed over to a purchaser in a paper container so that the product can be easily carried. The paper container at this time is usually a paper bag that is open on one side, and a paper handle may be attached to the paper bag. On the outside of the paper container, the names of shops, department stores, brand marks, etc. are neatly printed, and many of them are elaborately designed so that buyers can carry them comfortably. Although these paper containers may be reused as a container for carrying goods by the purchaser, usually paper containers are provided free of charge for every purchase, so they are stored at hand and used as containers. Even so, many things have more opportunities to be disposed of as garbage than being reused. Paper containers such as handbags provided at such department stores are often made of high-quality paper, and simply disposing of them is a waste of resources, so that it is required to use them effectively.

  For example, when a book is purchased at a bookstore, the book is placed in a paper bag and delivered to the customer, or to a desired customer, the book that has been sold is put in a paper bag with a paper book cover and delivered. It is often done. Recently, online sales of books on the Internet have become common. Books purchased through online sales are placed in envelopes and packaging bags and delivered to customers by mail or courier, so the book cover is not attached to the book. The book purchaser had to prepare a new book cover. In addition, paper bags at bookstores and envelopes such as envelopes sold online are usually discarded as they are when the intended purpose of use is achieved. Similarly, envelopes for storing and transporting documents and the like as mail were also taken out and the envelopes were discarded in the trash. Since this situation is a waste of resources, it has been proposed to reuse used envelopes, which are a type of paper container.

  In a book cover in which a cover portion 1 that covers the cover of a book and a fold portion that is folded inside the cover portion are provided continuously at both ends of the cover portion, a stamp affixing column on the surface of one of the fold portions And an address field, and a book cover (Patent Document 1) that allows easy mailing of a book in which a glued tongue piece is extended on the lower side of one of the folding parts, or a release paper adhered to the tip of the opening In an envelope bag having an adhesive surface, an envelope / book cover (Patent Document 2) in which a perforation is provided at a desired position on the bottom of the envelope or on the bottom and the opening side has been proposed.

  In addition, plastic front and back sheets are connected in a bag shape on three sides, and the distance between two opposite sides of the three sides corresponds to the sum of the width and thickness of the book to be covered and one side between the two sides. In the envelope in which the bottom is formed and an opening for inserting / removing the contents is formed at a position facing the bottom, the upper side of the envelope is removed by connecting the two sides facing the front and back sheets A horizontal cut line for the book is formed at a position corresponding to the height of the book to be covered from the bottom, and the book is connected to the back sheet at the vertical cut line and the bottom of the book connected from the horizontal cut line to the bottom. A bottom horizontal cut line connecting between the vertical cut lines is formed, and an interval corresponding to the thickness of the book to be covered on the front sheet at a position between the vertical cut lines of the book is provided. Book borders are shaped It can be mentioned envelope (Patent Document 3) as the book cover being.

Furthermore, at least a first surface portion, a second surface portion provided opposite to the first surface portion, and an opening for inserting an object into a space portion formed between the first surface portion and the second surface portion It is possible to form a book cover by providing a cutting line for cutting a part of the second surface portion on the second surface portion and inserting a cover of the book into the space portion from the cut cutting line. Book cover combined bag. (Patent Document 4) or one end of a book body is bent inward, the upper end and the lower end are bonded to each other, a bag portion is provided, and the bent portion on the opposite side is left extended, and the protrusion is at the center of the end portion or a portion equivalent thereto And a book cover / sealing wrapping paper (Patent Document 5) in which a re-peeling adhesive layer is applied on the inside and a release paper is temporarily attached thereon.
However, since the shape and structure of the book cover created from these envelopes are restricted by the vertical or horizontal width of the envelope, there is a problem that the relationship between the size of the envelope and the book to which the cover is attached is limited. There are few proposals for effective reuse of paper containers other than envelopes.

For example, by printing origami, coloring book, paper airplane, modeling with cut paper, cut paper, etc. that become paper toys on the inner surface of the paper container, it can also contribute to children's emotional education using this (Fig. 1). And 2). In addition, a beautiful calendar can be printed according to the season, and pictures such as photographs and reproductions can be used for interior decoration. Furthermore, a flower book, a picture, a landscape, etc. can be printed on the inner surface of the envelope or bag, and the book can be cut out to make a fun book cover. On the surface of the book cover, the company, school name, product photos, logos, etc. can be entered for advertising purposes, and barcodes and two-dimensional codes, which are information transmission codes, are printed. By doing so, it is possible to promote information exchange via the Internet with the manufacturer or seller of the product.

  Recycling of used paper containers is facilitated by facilitating cutting with a separation line. For example, in order to use an envelope, which is a type of paper container, as a book cover, it has to be separated with a separation line after taking out the stored items. Is done. At this time, the recipient of the envelope reuses the envelope as a book cover, which leads to effective use of limited resources. In addition, by providing a blank space on the envelope surface, it is easy for the recipient to write notes on the envelope body, and there is no need to select a writing instrument. It is extremely easy to use.

In addition, the envelope and hand-held document container are provided with a side edge sealing part between the front sheet and the back sheet, and a regulation part that joins the front sheet and the back sheet between the separation lines. Thus, the movement of the stored item in the envelope can be restricted, and the main body of the container such as the envelope is not damaged by the content, and the content is fixed at a predetermined position. Specifically, (a) the restriction part has a continuous or intermittent envelope of one or more lines, dots, or bands (see, for example, FIGS. 4 and 5), (b) high-speed application Envelope formed by applying glue line to form the sealing and regulating part at high speed and simultaneously by the machine (see FIG. 4) (c) An envelope in which the inner space of the envelope is narrowed toward the lower end by the regulating part Can be provided. In addition, since the joint portion and the sealing portion can be formed simultaneously and at high speed, the processing time per sheet can be reduced, and the manufacturing cost of the envelope can be reduced.
Furthermore, by using a linear glue wire, the amount of adhesive used is less than that of belt-like coating, it can be applied at high speed, and a specific sealing part can be formed without damage during mailing. By selecting and using an adhesive, the manufacturing cost of the envelope can be further reduced.
As mentioned above, it cannot be overemphasized that the effect demonstrated as an example of an envelope is an effect produced also in containers other than an envelope.

The present invention provides a separation line characterized in that one or more types selected from patterns, characters, photographs and symbols and a separation line for cutting out at least one of the outer circumferences are provided on the inner surface of the paper container. The present invention relates to a paper container that can form various useful articles when separated along the line. For example, the main body can be reused as a book cover or as a paper toy, which leads to effective use of resources. Also, by providing printing such as flower patterns, paintings, landscapes, etc. on the inner surface of the envelope on the front side of the book cover, it can be used as a fun book cover. You can also enter photos, paintings, paper toy company / school names, product photos, logos, and information codes. The paper container of the present invention is provided with an opening, and an article is inserted and / or removed through the opening. For example, if the paper container is an envelope, it is often sealed after a document or the like is inserted from the opening before use, but may not be sealed. In the case of a paper bag for carrying, etc., the opening is maintained before and after use, and articles are inserted and removed from the opening.
Next, the present invention will be described in detail. As a paper container, an envelope is mainly specifically described as a representative of a bag-shaped container, but it goes without saying that the present invention can be applied to other paper containers such as a hand-held container other than an envelope.

[Create paperwork such as toys]
A paper toy is obtained by cutting origami, a coloring book, a paper airplane, modeling with a cut paper, a cut picture, etc. on the inner surface of the paper container. In addition, if pictures such as photographs, duplicate pictures, and beautiful calendars are printed according to the season, these can be used for interior decoration. For example, while playing with paper has been favored over the ages, origami, cut paperwork, paper sumo, assembled animals, etc. are typical examples. FIG. 1 shows an example of cut paper work. Kirigami is a handicraft that cuts out paper to create various shapes. Among them, “Crimper” was cited as an example. A square origami shape is printed on the back side of the envelope, and a cut line pattern is drawn on the quadrant. In this pattern, it is difficult to determine what kind of pattern can be formed by cutting it out, but after cutting a square from the envelope, turning it back along the dotted line, and cutting it along the solid line, it is shown in the upper part of FIG. You can get the Hishiwa pattern. Such cut paperwork is known in many different forms and can print different patterns for each envelope.

Also, in FIG. 2, two wrestlers used for paper sumo are printed, and these can be cut out, tackled on a small box, etc., beat with a fist, etc., and played with fighting. This is a traditional game that has been popular among young children. You may print a ring with a wrestler.
In FIG. 1, a calendar for the month according to the date and time when the calendar is printed and the envelope is used is printed. Such a calendar can be made suitable for interior decoration by arranging photographs and paintings. For envelopes, it is suitable to print a small desktop calendar. As for the above-mentioned envelopes for paperwork, formation of separation lines, and the like, those used for making a book cover described below can be used as appropriate.

[Print information code]
Information can be exchanged between the manufacturer or seller of the product and the purchaser by printing an information code such as a picture or pattern on the inner surface of the paper container. Although it is possible to provide unilateral information from the provider by means of characters, symbols, etc. on the inner surface of the paper container, it is often troublesome to access the seller from the purchaser. In such a case, by printing a bar code or two-dimensional code including information read by a mobile phone, mutual information exchange can be smoothly performed through the Internet. For example, the website of the store, company information, electronic library site information, examination information for various schools and universities, event organizer information, exhibition information, etc. are printed as codes. Mutual information via the Internet from a personal computer or mobile phone Exchange becomes easy. In addition, it is possible to make an order for a product ordering code, a code for accessing a questionnaire response column, an order for a symbol printed on a paper container to be used for the next delivery of an ordered item, and the like.
Also, when forming a reply postcard using the inner surface, when the postcard arrives at the sender, the pre-printed barcode or secondary code is read to identify the orderer or analyze the order details. It can be used as information to arrange or information on order shipment. 7 and 2 show an example in which a return envelope or a postcard is printed on the inner surface of the envelope. The reply envelope or postcard is pre-printed with a zip code, address, destination, etc., and a separation line is provided so that the periphery can be easily cut. For example, a reply envelope can be provided with a field for entering a reply to a questionnaire from a respondent, an opinion, and the like (see 1 in FIG. 7). This envelope consists of the a side on which the address is printed, the b side which is the back side of the reply envelope, and the communication field c side from the responder. After the c side and b side are folded and overlapped, the a side By integrating, an envelope in which the contents described in the communication column cannot be seen from the outside is completed. In the case of a postcard, a communication field is provided on the back surface (outside) of the original envelope.

[Create book cover]
[Envelope structure]
An example of the basic structure of the envelope used as the paper container of the present invention will be described with reference to FIG. FIG. 3 is an unfolded drawing of an envelope which is one of the preferred embodiments of the present invention, which has a continuous front sheet 1 and a back sheet 2, and has a sealing piece 3 at the upper end of the front sheet 1. The front sheet 1 and the back sheet 2 are folded at the center fold line 4 so that the two sides are joined by the edge portions 6 and 7, and an envelope is formed in which a portion with the sealing piece 3 is opened. In addition, as another type of envelope, prepare a sheet of paper that is rectangular and cut off both ends of its right end portion to form a sealing piece 3, and apply an adhesive to its upper and lower ends, An envelope (see FIG. 8) formed by overlapping and adhering with the sealing piece 3 at the right end can be used.
A book cover can be formed by cutting from these envelopes. For example, in an envelope, continuous separation lines 10a, 10b, 11a, 11b are provided, and 11a, 11b and 10a, 10b intersect at right angles at their ends. These separation lines are parallel to the edges of the front and back sheets. The separation line defines the size of the book cover, which is the length of the cover, back cover, and back cover of the book to which the book cover is to be attached, and the folding back for locking the book cover to the book. It has a thickness and width and is rectangular.
The inner surface of the envelope is a surface that serves as a cover of the book cover, and one or more selected from patterns, characters, photographs, and symbols are provided by printing or the like, and the book cover having an aesthetic sense can be cut out.

  When the front sheet 1 and the back sheet 2 are folded at the center fold line 4 of the envelope and the edges are overlapped and sealed and assembled into an envelope, the separation lines of the front sheet 1 and the back sheet 2 are provided so as to overlap as much as possible. It is preferable to facilitate the separation of the book cover. However, in the developed view shown in FIG. 3, the position corresponding to the boundary line (book cover folding line) of the book cover or the back cover and the back cover of the book cover and the fold of the envelope are provided. Therefore, when the envelope is formed, the separation lines 10a and 10b do not overlap, but the separation lines 11a and 11b are provided so as to overlap when the envelope is formed. The separation lines can be extended to the outer edge so that the periphery can be easily cut out and the cut position is not mistaken. Since the strength of itself may be reduced, it is necessary to consider the material of the envelope, the weight of the stored items, and the like. In addition, when the separation line is formed by printing, it can be displayed as a cut line at a density that does not interfere with address writing on the surface of the envelope.

  In FIG. 4, an adhesive line 30 for forming a restricting portion is provided between the separation line 10 b of the envelope back sheet 2 and the side adhesive wire 8 to restrict the movement of the stored items in the envelope. In FIG. 4, the restricting portion is made of an adhesive (glue), the vertical line paste is applied with a little over 1 mm, and becomes a glue line (regulating portion) having a width of 2 to 3 mm after bonding. The glue line is preferably provided at a position as close as possible to the separation line as long as the adhesive does not cover the vertical separation lines 10a and 10b when the front and back sheets are bonded. The position where the bonding line (restricting portion) 30 is provided can be moved between the separation line 10b and the side bonding line 8 according to the size of the document stored in the envelope, but the bonding line 30b is bonded to the vertical separation line 10b. It is preferable to keep the line (restricting portion) 30 as close as possible to suppress a decrease in the strength of the envelope due to a separation line such as a perforation.

[Envelope material]
As the material of the present invention, any material can be used as long as it is a material used as an envelope or a book cover. For example, from natural pulp paper, recycled pulp paper, kraft paper and the like. Sheet-like materials (synthetic paper) made by specially processing materials such as polyester and polyethylene, and applying white pigment on the surface to make it printable like paper (synthetic paper), paper, Various materials such as those made by laminating plastic and metal foil are used. Any sheet having strength that can be used as a book cover is not limited.

Even in the case of a windowed envelope for disclosure of inclusions, it can be used as an envelope that can form the book cover of the present invention. For example, a window can be used as part of a book cover design, and if a part of the title displayed on the cover of a book can be seen from the window, the book is confirmed through the book cover. be able to. In the case of an envelope made of an opaque material, the window provided on the envelope is punched in advance at a predetermined position and a transparent film is pasted on the window portion, or on the entire back side of the envelope paper punched out at a predetermined position. For example, it can be obtained by applying a transparent film such as polyvinyl chloride, polyethylene, or polypropylene. In addition, by printing ink with a special watermark effect, it can also be obtained by changing the part of the paper to make it transparent, which is inferior to film but not peeled off, in the case of encapsulation work There are advantages such as no catching. In addition, since there is no process of punching and pasting a film, there are advantages in terms of speed and cost in creating an envelope.
The size, shape, and the like of the window are designed according to the relationship between the enclosed material, the illustrations, photographs, and the type of books on which the book cover is provided. Moreover, the window for enclosure disclosure may be one place for normal use, but two or more windows may be provided. Furthermore, illustrations and photographs may be printed not only on the envelope surface and the inner periphery of the window portion but also on a transparent film attached to the window portion.

[adhesive]
The sealing part and / or the regulating part is formed by welding and / or adhesion by an adhesive, but the adhesive used in the embodiment in which the sealing part and the regulating part are formed by adhesion by an adhesive Will be described.
In order to produce the envelope of the present invention, an adhesion method according to the material is employed. Adhesives are not limited to their types and materials, but those that have been used in the past can be used. Solvent volatilization type adhesives, hot melt adhesives, pressure sensitive adhesives, rewet adhesives, reactive adhesives Agents, re-peelable adhesives, and the like.
For example, there is no adhesive at normal temperature and normal pressure as an adhesive, and adhesiveness is exhibited by pressing or heating and pressing with the adhesive layers facing each other. A peelable adhesive can be used. Removable glues are made from a mixture of synthetic rubber latex and wax emulsion, in particular releasable glue made from styrene-butadiene copolymer latex and paraffin wax emulsion and / or microwax emulsion. preferable. Envelopes that use re-peelable adhesive do not peel off during use from the time the envelope is made until it is sent, but can be easily peeled off from the corner cut when opening, making it easier to reuse envelopes .

For bonding between paper and paper or between paper and plastic, for example, a vinyl acetate adhesive is used. Any adhesive can be used as long as it is a normal type, but the type of adhesive affects the precise processing when using a high-speed coating machine. In order to bond paper and paper or paper and plastic film, a high-speed coater is often used to apply an adhesive to a substrate (for example, paper).
As the adhesive, a vinyl acetate adhesive or an ethylene / vinyl acetate adhesive is often used. Synthetic resin emulsion type water-based adhesives mainly composed of vinyl acetate resin and ethylene vinyl acetate copolymer resin are used for various applications such as paper / paper adhesion, metal foil, plastic film / paper adhesion, etc. Yes. In order to control the applicability of the adhesive, the viscosity and viscosity (eg, thixotropic, Newtonian, dilatancy) can be controlled. In addition, for vinyl acetate resin emulsions using polyvinyl alcohol as a protective colloid, the adhesion performance is impaired by the method of controlling viscosity by adding inorganic and / or organic electrolytes to prevent “glue skipping”. Of course, it is possible to obtain an adhesive that does not cause “glue skipping” when the adhesive is applied.

  Examples of the adhesive composed of a vinyl acetate polymer emulsion include 25 to 30% by weight of vinyl acetate polymer, 5.0 to 10% by weight of n-butyl phthalate, and 55 to 60% by weight of water. Can give. In addition, an adhesive composition obtained by adding 0.1 to 10 parts by mass of a surfactant to 100 parts by mass of a vinyl acetate adhesive and / or an ethylene-vinyl acetate adhesive is used. It is preferable that all or part of the surfactant is one or more of acetylene alcohol, acetylene glycol, or ethylene oxide adducts thereof. The ethylene-vinyl acetate resin emulsion adhesive is an aqueous dispersion adhesive mainly composed of an emulsion of a resin obtained by copolymerizing ethylene vinyl alcohol (EVA) and vinyl acetate. This is a cloudy aqueous solution in which 10 to 30% ethylene monomer is mixed with vinyl acetate monomer and emulsion polymerization is carried out under high pressure to make an emulsion. Excellent water resistance, weather resistance, alkali resistance and faster bonding speed than emulsion of vinyl acetate resin alone, so it can be used in the field of bookbinding, bag making, etc. used.

  In the present invention, the above-mentioned adhesive suitably used for laminating paper, wood, plastic film, etc. is used. In this case, particularly, high-speed application, specifically, operation at a coating speed of 90 m / min or more is performed. It is effectively used in coating machines. Note that the coating speed of 90 m / min or more corresponds to a speed of 300 sheets / min or more, and is therefore preferably used in a paper bonding method with such a coating speed. No “glue skipping” occurs at the time of high-speed application of the adhesive, and application unevenness does not occur.

The vinyl acetate adhesive and / or ethylene-vinyl acetate adhesive used in the present invention is mainly composed of vinyl acetate or ethylene and vinyl acetate as a main component in the polymer, such as polyvinyl alcohol, hydroxymethyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose, etc. An emulsion synthesized by emulsion polymerization using a water-soluble polymer as a protective colloid, or a mixture of this emulsion with a plasticizer, a solvent or the like is preferred.
The desirable emulsion used as the vinyl acetate-based adhesive will be further described in detail. (1) 50 to 100% by mass of vinyl acetate and (2) Unsaturation having radical polymerization ability such as methyl acrylate and ethyl acrylate One type or two or more types of group-containing monomers are synthesized by emulsion polymerization from 0 to 50% by mass. If the vinyl acetate is less than 50% by mass, a desired viscosity cannot be obtained, and application unevenness may occur when the adhesive is applied.

  Desirable emulsions used as the ethylene / vinyl acetate adhesive are (1) 5-35% by mass of ethylene, (2) 50-95% by mass of vinyl acetate, (3) methyl acrylate, acrylic One or more unsaturated group-containing monomers having radical polymerization ability such as ethyl acid are synthesized by emulsion polymerization from 0 to 45 mass%. If the ethylene content is less than 5% by mass, the plasticizing effect of ethylene may not be obtained. On the other hand, if it exceeds 35% by mass, the emulsion polymerization reaction becomes unstable, and a mechanically stable emulsion may not be obtained. If the vinyl acetate is less than 50% by mass, a desired viscosity cannot be obtained, and application unevenness may occur when the adhesive is applied. Moreover, when vinyl acetate exceeds 95 mass%, the plasticizing effect of ethylene may not be acquired.

  Various known water-soluble polymers are used as protective colloids used in emulsion polymerization. Water-soluble fiber derivatives such as fully saponified polyvinyl alcohol, partially saponified polyvinyl alcohol, hydroxymethylcellulose, hydroxyethylcellulose, carboxymethylcellulose, methylcellulose, starch, polyacrylic acid and its salts, polymethacrylic acid and its salts, polyacrylamide, polyacrylic acid Examples thereof include synthetic polymer electrolytes such as partially saponified products of esters. The amount of the protective colloid used is usually 0.5 to 30% by mass, desirably 2 to 20% by mass, based on the monomer.

As unsaturated group-containing monomers having radical polymerization ability used for emulsion polymerization, ethylenically unsaturated monocarboxylic acid esters such as methyl acrylate, ethyl acrylate, butyl acrylate, 2-ethylhexyl acrylate, methyl methacrylate, Ethylenically unsaturated polycarboxylic esters such as dimethyl itaconate, diethyl maleate, monobutyl maleate, monoethyl fumarate and dibutyl fumarate, ethylenically unsaturated monocarboxylic acids such as acrylic acid, methacrylic acid and crotonic acid, itacone Ethylenically unsaturated polycarboxylic acids such as acid, maleic acid and fumaric acid, N-methylol group-containing monomers such as N-methylol acrylamide, epoxy group-containing monomers such as glycidyl methacrylate, and 2-hydroxyethyl methacrylate Lumpur group-containing monomers, amide group-containing monomers such as acrylamide, and the like.
In the case of the vinyl acetate emulsion, the amount of the unsaturated group-containing monomer having radical polymerization ability is 0 to 50% by mass, more preferably 0 to 40% by mass, based on the monomer. On the other hand, in the case of an ethylene / vinyl acetate emulsion, the content is 0 to 45% by mass, more preferably 0 to 30% by mass, based on the monomer.

Any known emulsion polymerization method can be employed for the emulsion polymerization. Monomers and other polymerization aids (for example, polymerization initiators such as ammonium persulfate, chain transfer agents such as mercaptans, pH adjusters such as sodium carbonate, various antifoaming agents, etc.) may be added all at once. , May be added continuously, or a part thereof may be added continuously or divided during the polymerization.
As polymerization initiators used in emulsion polymerization, persulfates such as ammonium persulfate and potassium persulfate, azo compounds such as 2,2′-diamidino-2,2′-azopropanedihydrochloride, azobisisobutyronitrile, cumene Examples include peroxides such as hydroperoxide, benzoyl peroxide, and hydrogen peroxide. Moreover, a well-known redox-type initiator, for example, potassium persulfate, sodium hydrogensulfite, etc. are mentioned. The usage-amount of a polymerization initiator is 0.1-5 mass% normally with respect to a monomer, Preferably it is 0.2-2 mass%.

The polymerization temperature for carrying out the emulsion polymerization is usually 10 to 90 ° C, preferably 50 to 80 ° C. The polymerization time is desirably 3 to 20 hours. This polymerization is desirably performed in an atmosphere of an inert gas such as nitrogen gas.
The vinyl acetate adhesive and the ethylene / vinyl acetate adhesive (emulsion) thus obtained may be mixed with a plasticizer, a solvent or the like, if necessary. Examples of the plasticizer include phthalate ester plasticizers such as dibutyl phthalate, phosphate ester plasticizers such as triethyl phosphate, polyoxyalkylene monophenyl ethers such as diethylene glycol monophenyl ether, 2,2,4-trimethyl- 1,3-pentanediol or esters thereof may be mentioned.
The amount of the plasticizer added is usually 0 to 30% by mass, desirably 0 to 20% by mass with respect to vinyl acetate and / or ethylene / vinyl acetate emulsion. When the plasticizer addition amount exceeds 30% by mass, the film strength of the adhesive may be reduced, and the adhesive strength may be reduced.

  Solvents include (1) organic solvents such as toluene, methyl acetate and ethyl acetate, or (2) alcohols such as methyl alcohol and ethyl alcohol, polyhydric alcohols such as ethylene glycol, propylene glycol and glycerin, butyl cellosolve and propylene glycol. Examples thereof include water-soluble organic solvents such as glycol ethers such as monomethyl ether. The amount of the solvent added is usually 0 to 40% by mass, desirably 0 to 30% by mass with respect to vinyl acetate and / or ethylene / vinyl acetate emulsion. When the amount of the solvent added exceeds 40% by mass, the drying rate of the adhesive is slowed and the initial adhesive force is reduced.

[Separation line]
The separation line is formed by a printing line, a perforation line, or a half-cut process. The envelope of the present invention is also intended to be reused by a recipient as a book cover or the like, and it is necessary to separate or cut the book cover from the shape of the envelope. The position at which separation is performed is indicated by separation lines 10a, 10b, 11a, and 11b provided in advance on the envelope, but this separation line is most easily revealed by printing the separation line on the surface or inner surface of the envelope. Can serve the minimum purpose.

  In addition, the vertical separating lines 10a and 10b and the horizontal separating lines 11a and 11b used in the envelope of the present invention may be perforated lines having the same form as the separating lines such as stamps, and are recently used for all separating lines. Half-cutting, so-called half-cutting, is convenient for the user. Moreover, although the structure by the process close | similar to a half cut can be used by punching, the formation method and its structure are not limited about the vertical separation lines 10a and 10b and the horizontal separation lines 11a and 11b in an envelope. Any processing method and structure may be used as long as the user can easily perform the separation work.

  A separation line composed of a perforation line is usually provided when a shape corresponding to the development of the envelope is cut out from the sheet. Cutting along the developed view may be performed simultaneously with the printing of the book cover on the inner surface of the envelope, and printing, cutting out, and perforation are often performed in one step. There are various forms of the perforation line, and can be selected as appropriate. For example, the perforation line (cutlery line) can be selected by pressing a blade (Thomson blade, rotary blade, etc.) against the sheet with a punching machine (die roll, punching machine, etc.) Punching marks) are formed. The perforation line as the separation line is an example in which relatively long slits are repeatedly formed at regular intervals, short slits are formed at a fine pitch, repeated mixing of holes with different hole diameters, perforation lines with mixed holes and half cuts, Examples include a micro perforation line in which the cut surface after separation is not rough, and a perforation line in which finger damage is prevented by the cut surface. The separation line can be extended to the peripheral edge. By cutting this portion in advance, separation and cutting along the separation line is facilitated. In addition, it is desirable to design the separation line of the back sheet and the separation line of the front sheet to coincide when the envelope is formed by bonding the developed front sheet 1 and the back sheet 2 together.

When a separation line is formed in a container made of paper by a perforation or the like, if some force is applied to the end portion of the perforation, the separation line may naturally proceed from the end portion. In order to eliminate such a phenomenon, it is desirable that only the end of the separation line is strengthened to such an extent that it cannot be cut naturally, and the end of the separation line is cut only by the force of a human finger. For example, a 1 mm cut is formed inside, leaving 2 mm that is not cut from the edge of the paper, and a 2 mm uncut portion and a 1 mm cut are formed. If a fine perforation is formed inside the micro sewing machine, it will not be naturally separated from the separation line during use as containers.
In addition, since the part where the separation line intersects at an acute angle or the part where the separation line curves at an acute angle is difficult to cut cleanly, it is preferable to avoid a sharp change in the separation line as much as possible. When the curved portion is formed with a large curvature like a separation line, excessive force is not applied and the paper is easily separated, and the paper is hardly damaged during separation.

[Sealing part and / or regulation part]
The sealing portion and / or the regulating portion is formed by welding and / or adhesion with an adhesive.
The sealing part is formed by adhering the front sheet and the back sheet. For the formation of the restricting portion formed by joining the front sheet and the back sheet, an adhesive layer is usually formed at an appropriate position on the inner surface of the envelope before completing the envelope from the sheet, and when the envelope is completed Can be formed.
Since the restricting portion is formed so as to make the inner shape of the envelope a specific shape, it should not be left on the cut book cover. Therefore, the restricting portion is provided between the end portion of the completed envelope and the separation line, and the structure may be one or a plurality of continuous lines or strips, discontinuous lines, spaced apart. It may be a row of spots. The restricting portion is preferably provided so that the storage portion narrows downward from the opening of the envelope. By doing so, the area around the opening is wide, so it is easy to insert the stored item into the envelope. After storing, the lower end of the stored item is limited in movement by the coupling part, so the stored item can be moved. It is possible to prevent the stored items and the envelope from being damaged by such as.
When the sealing portion and the regulating portion are formed by the same means, they can be performed in the same step, preferably at the same time. That is, the restricting portion can be formed integrally with the sealing portion at the side end.

  Further, the restricting portion can be provided by being joined with the same adhesive as the adhesive used for forming the side end seal. The preferable aspect is that the adhesive forming the regulating portion is provided as a continuous linear glue line having the same composition as the adhesive used for forming the side end seal and the bottom end seal, Preferably, a continuous linear glue line is formed by a high-speed coating machine to form the sealing at the side end portion and the sealing at the regulating portion and the lower end portion. A continuous linear glue line for forming the restricting portion is applied at a position close to the vertical separation line.

[Use as an envelope for direct mail]
When the envelope of the present invention is used for mail or mail service, a label printed with the address and the name of the addressee can be affixed to the front side of the envelope. Use of the surface is not limited. Since there are wide margins on the front and back surfaces of the envelope, they are used in various ways. For example, an envelope inner surface sheet serving as a cover of a book cover can be formed transparent so that the contents can be confirmed, and an advertisement can be printed on the entire rear surface. It is also possible to sell it as a cheap envelope and book cover with some of the sponsor's advertisements and promotions printed. It is convenient to provide a white writable surface on the envelope surface so that a memo can be written with a pencil, brush, or pen. In this way, by adding a function that is convenient for the use and reuse of envelopes, it is possible to improve the open rate by the recipient of direct mail, and to promote mail-order sales and advertising effects.
