Description

  The present invention relates to an envelope, and more particularly to an envelope that can be easily opened and prevents an object to be enclosed from falling off during transportation.

  Envelopes are often used to send documents, letters and cards. For example, in a standard envelope, an inlet is provided at one edge of a bag made of a substantially rectangular upper sheet and lower sheet, and a sealing piece is formed integrally on the upper sheet, and a document or A structure in which a sealing piece seals a slot after a letter is put is common.

  However, when the envelope is received in the standard envelope, the sealed piece portion is cut with a scissors or knife or broken by hand, but there is a possibility that the enclosed document or letter may be accidentally damaged.

  On the other hand, an envelope has been proposed in which a portion other than the insertion port is quasi-bonded so that it can be peeled off when the rectangular upper sheet and the lower sheet are bonded, and can be peeled off and opened from the portion other than the insertion slot. (Patent Document 1).

Japanese Patent No. 3731137

  However, in the envelope described in Patent Document 1, since the parts other than the inlet are pseudo-adhered, the pseudo-adhered part may be peeled off for some reason during transportation, and the enclosed document may be dropped.

  In view of such problems, an object of the present invention is to provide an envelope in which an important sealed object is not dropped while ensuring easy opening performance.

  Therefore, an envelope according to the present invention is an envelope in which an insertion port of an encapsulated body is sealed with a sealing piece, and is composed of a first sheet portion, a second sheet portion, and a third sheet portion, and the first sheet A sealing piece is integrally formed on the upper edge of the part, and each of the first sheet part, the second sheet part, and the second sheet part and the third sheet part is formed in a bag shape in which an encapsulated body is accommodated. The lower end edge part of one bag-like part is provided so that it can be cut off, the other lower end edge part is provided so that it can be peeled or cut off, and the lower end edge part is peeled off or cut off to form both bags Each of the parts is designed to be opened.

  One of the features of the present invention is that two bag-like portions are formed, the lower edge portion of one of the two bag-like portions is cut off and opened, and the lower edge portion of the other bag-like portion is peeled off or cut off. It is in the point which opened it.

  As a result, if an important encapsulated object is stored in a bag-shaped part opened by cutting, the encapsulated object will not fall off due to impact during transportation unless the lower edge part is cut off. You can safely and reliably transport valuables such as documents, cards, etc.

  On the other hand, in the case of an encapsulated body that requires quick opening, a bag-like portion that is opened by peeling is provided, and if encapsulated in this bag-like portion, the encapsulated body can be quickly opened and easily taken out. it can.

  For example, a cut-and-open portion is provided in the lower edge portion of the bag-like portion of the first sheet portion and the second sheet portion, and the lower edge portion of the bag-like portion of the second sheet portion and the third sheet portion is pseudo-bonded so as to be peelable Can be configured to.

  Also, a cut-and-open portion is provided at the lower edge portion of the bag-like portion of the first sheet portion and the second sheet portion, and a cut-off portion is also provided at the lower edge portion of the bag-like portion of the second and third sheet portions. It can be constituted as follows.

  The first sheet portion and the second sheet portion may be formed into a bag shape by bonding the necessary edges of the two sheets, but the lower end edges of the first and second sheet portions are made continuous and folded. The left and right edges may be bonded to produce a bag shape. That is, the lower end edges of the first sheet portion and the second sheet portion are made continuous, and the three outer end edge portions on the left and right sides and the lower side are bonded together, and a cut-opening portion is formed along the immediately upper edge of the bonding portion. be able to.

  The adhesive in this case may be a non-peelable adhesive, but if a peelable adhesive is used, the first and second sheet portions can be expanded to see the internal printing / printing portion, and direct The function as an email can be improved.

  The second sheet portion and the third sheet portion may be formed into a bag shape by bonding the necessary edges of the two sheets, but the upper and lower edges of the second and third sheet portions are continuous and folded. Alternatively, the left and right edges may be pseudo-bonded with a pseudo-adhesive to produce a bag shape.

  In this case, it is also possible to form a cut-opening portion along the immediately upper edge of the pseudo-adhesion portion of the second sheet portion and the third sheet portion.

  By the way, when opening by a cut opening part, there exists a possibility that a to-be-enclosed body may be damaged, when cutting by a cut opening part. Therefore, the lower edge portion of the bag-like portion of the first sheet portion and the second sheet portion and the lower edge portion of the bag-like portion of the second sheet portion and the third sheet portion are bonded or pseudo-bonded, and If the cut-opening part is formed along the upper edge of the bonded part, the possibility that the encapsulated body is accidentally damaged at the time of opening can be eliminated.

  The material of the first, second, and third sheet portions is not particularly limited, and synthetic resin material, synthetic paper, paper, synthetic paper laminated with synthetic resin film, paper, or the like can be used.

  The cut opening part may be formed by micro perforation, perforation or half cut, and may be cut off. Alternatively, a thread is embedded in the cut opening part of the first and second sheet parts, and the thread is pulled to cut off. You may do it.

  The pseudo-adhesion can be realized, for example, by using an adhesive having an adjusted adhesive strength so that the adhesion site can be peeled off.

  Further, when the user uses the envelope of the present invention, the user is provided with a structure in which the sealing piece is opened and the third sheet portion is not pseudo-bonded to the second sheet portion. The sheet portion may be pseudo-bonded to the second sheet portion, and the charging port may be sealed with a sealing piece.

  Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 to 4 show a preferred embodiment of an envelope according to the present invention. The envelope 10 of this example is composed of first, second, and third sheet portions 11, 12, and 13 that are continuous with each other, and a sealing piece 14 is continuously formed on the upper edge of the first sheet portion 11. ing.

  The first sheet portion 11 and the second sheet portion 12 are configured in a bag shape in which an encapsulated body is housed inside by an adhesive 16 that can be peeled off at both left and right end edges and lower end edges, and in a lower portion. A perforation (cut-opening portion) 15 is provided along the immediate upper edge of the pseudo-adhesive portion, and the object to be encapsulated can be taken out by being cut at the perforation 15.

  The second sheet portion 12 and the third sheet portion 13 are configured in a bag shape in which an encapsulated body is housed inside by an adhesive 17 that can be peeled off at both left and right edge portions and lower edge portions, and a lower outer edge. The object to be encapsulated can be taken out by peeling from the pseudo-adhesive portion.

  The pseudo-adhesives 16 and 17 cannot be peeled off so that the bonded portions of the first, second and third sheet portions 11, 12, and 13 are peeled off from the encapsulated body due to impact during transportation. However, it is preferable to adjust so as to have sufficient adhesive strength.

  When manufacturing the envelope 10 of this example, the paper is punched out from the base paper. Three creased lines 20 to 22 are put in parallel with each other on the paper, and the first, second and third sheet portions 11, 12, 13 and the sealing piece 14 are formed.

  A stripping adhesive 16 is applied to the left and right ends and bottom edges of the back surfaces of the first and second sheet portions 11 and 12 in a strip shape, and the surfaces of the second and third sheet portions 12 and 13 are applied. A stripped adhesive 17 is applied to the left and right edges and the lower edge. The adhesives 16 and 17 may be applied to the base paper in advance, or may be applied to the paper after being cut from the base paper.

  The first, second, and third sheet portions 11, 12, and 13 are bent at the folding lines 20 to 22, and the left and right end edges and the lower end edge portions of the first and second sheet portions 11 and 12 are bonded with the adhesive 16. A bag-like portion is formed by quasi-bonding in a strip-like manner so as to be peelable, and the left and right edges and bottom edge portions of the second and third sheet portions 12, 13 are quasi-peeled in a strip-like manner by the adhesive 17 Adhering to form a bag-like part.

  Further, perforations 15 are formed in the lower portions of the first and second sheet portions 11 and 12 along the immediate upper edge of the pseudo-adhesive portion. The perforation 15 may be inserted when punching out the paper from the base paper, may be inserted when the folding lines 20 to 22 are inserted, or may be inserted after the envelope 10 is assembled and bonded.

  Important items such as cards and letters are put in the bag-like portions of the first and second sheet portions 11 and 12, and less important items are put in the bag-like portions of the second and third sheet portions 12 and 13. In this example, since the envelope 10 is produced by folding one sheet of paper, the bag-like portions of the second and third sheet portions 12 and 13 have no insertion port, and the second and third sheet portions 12 are not provided. , 13 are folded and an object to be encapsulated is inserted therebetween, and then pseudo-adhered.

  In addition, since the bag-like portions of the first and second sheet portions 11 and 12 have an opening at the upper edge, the sealed piece 14 is inserted into the sealed body from the insertion port. Seal the inlet.

  When the envelope 10 of this example is received, as shown in FIG. 2, the second sheet 10 is peeled off from the corner portion of the lower end edge of the third sheet portion 13 without cutting or tearing the sealing piece 14 and opening the second sheet. The bag-like portions of the third sheet portions 12 and 13 can be quickly opened to take out the inclusions.

  Moreover, when the perforation 15 is cut off, the bag-like portions of the first and second sheet portions 11 and 12 can be opened without opening the sealing piece 14. In this case, the lower end edge portions of the first and second sheet portions 11 and 12 are adhered to the lower side of the perforation 15 with the adhesive 16, and the position of the lower end edge of the encapsulated body is higher than the perforation 15. Therefore, there is no possibility that the encapsulated body will be accidentally broken when the perforation 15 is opened.

  In the above, the first, second, and third sheet portions 11, 12, and 13 and the sealing piece 14 are configured by bending one sheet of paper, but as shown in FIG. 5, the first, second, and second sheet portions are formed. It is also possible to manufacture the three sheet portions 11 ′, 12 ′, and 13 ′ separately, apply adhesives 16 ′ and 17 ′ to necessary portions, overlap each other, and bond or pseudo-bond them to manufacture an envelope. In this case, the upper edge of the second and third sheet portions 12 ′ and 13 ′ may be sealed in the same manner as in the first embodiment, but when an adhesive 17 ′ is applied as shown in FIG. An inlet can also be formed.

  6 and 7 show a third embodiment, in which the same reference numerals as those in FIGS. 1 to 5 denote the same or corresponding parts. However, the reference numeral “is added to distinguish from the first and second embodiments. The envelope 10” in this example is the first, second, and third sheet portions 11 ″, 12 ″, and 13 ″. It differs from the envelope 10 of the first embodiment in that one bag-like portion can be simultaneously cut and opened at the lower perforation 15 ″ (cut-opening portion).

  When producing the envelope 10 "of this example, the paper is punched out from the base paper. Three folding lines 20" to 22 "are put in parallel with each other, and the first, second and third sheet portions 11", 12 ″, 13 ″ and sealing piece 14 ″. The first, second, and third sheet portions 11 ″, 12 ″, and 13 ″ have the same height.

  A peelable adhesive 16 '' is applied to the left and right ends and bottom edges of the back surfaces of the first and second sheet portions 11 ", 12" in a strip shape, and the second, third sheet portions 12 ", A peelable adhesive 17 '' is applied in a strip shape to the left and right edges and the lower edge of the surface 13 ''. The adhesives 16 ″ and 17 ″ may be applied in advance to the base paper, or may be applied to the paper after being cut from the base paper.

  The first, second, and third sheet portions 11 ", 12", and 13 "are bent by folding lines 20" to 22 ", and the left and right sides of the first and second sheet portions 11" and 12 "are bonded with an adhesive 16". Both end edges and lower end edge portions are pseudo-bonded in a strip shape to form a bag-like portion, and the left and right end edges and lower ends of the second and third sheet portions 12 ″, 13 ″ by an adhesive 17 ″ A bag-like portion is formed by pseudo-bonding the edge portion so as to be strip-like and peelable.

  Further, a perforation 15 "is provided along the immediately upper edge of the pseudo-adhesive portion in the lower portion of the first, second, and third sheet portions 11", 12 ", and 13". This perforation 15 "may be inserted when punching out the paper from the base paper, may be inserted when the folding lines 20" to 22 "are inserted, or may be inserted after the envelope 10" is assembled and bonded.
