Also,
(C) From the unfolded state of the envelope, the left and right guide pieces 40, 50 are folded back on the top surface 10, and the folded portion 30 is folded back on the opposite side so as to form a triangular prism from the second reference line 31, and above the triangular prism The upper stage 13 and the tongue 20 from the first reference line of the top and bottom are folded back so as to wind a triangular prism from the first reference line 11, and then the engagement piece 21 is inserted into the first incision 12 to form a stand. It is possible to provide the envelope.

  The shapes of the upper stages 41 and 51 above the first reference line of the left and right guide pieces are preferably substantially triangular.

  The maximum vertical width A of the tongue portion and the vertical width A ′ above the second reference line of the folded portion, the vertical width B above the first reference line of the ceiling and the vertical width of the lower portion from the second reference line of the folded portion. The ratio between B ′ and the vertical width C below the first reference line of the ceiling is such that the angle D between the front surface and the bottom surface of the triangular prism is 45 to 90 ° and the front surface and the back surface of the triangular prism are sandwiched between them. It is preferable that the angle E is determined to be 30 to 60 °.

  In the envelope of the present invention, the contents are usually enclosed in the envelope.

  The content is at least one selected from the group consisting of a calendar, a message card, a postcard, a painting and a photograph, for example.

  In particular, the contents are preferably a monthly calendar.

  It is preferable that the method for assembling the stand from the unfolded state is described in the envelope.

  The envelope of the present invention can be unfolded, and can be a stand for the contents of the envelope simply by folding the unfolded envelope. It is environmentally friendly that it can be converted into a stand by reassembly. Moreover, since each configuration of the envelope is diverted to each configuration of the stand, it is environmentally friendly in that no extra parts are required for the stand. Furthermore, the stand can be easily returned to the envelope by reassembly.

  The left and right guide pieces that support the contents during the envelope form pockets (holders) into which the contents are transformed into the stand, and at the same time serve as a foot part that supports the load of the entire stand to enhance protection of the stand To contribute. In particular, if the shape of the pocket portion is substantially triangular, the strength can be further improved, the contents X can be easily inserted, and the pocket can be prevented from rolling up.

  The envelope of the present invention eliminates the need for an adhesive or the like by using a paper-projected shape and a cut for a portion for opening and closing the envelope and a portion for fixing the shape of the stand. The pocket for inserting the contents when deformed into the stand can also be inserted and fixed by simply folding back the left and right guide pieces, so that it is not necessary to use an adhesive or the like for holding or fixing the contents.

  Envelopes enclosing contents such as a calendar can be easily distributed by mail, handing, etc., and can be used many times because no adhesive is used. Applications range from personal use for decorating Christmas cards, birthday cards, and other message cards, bromide photos, and paintings to business uses such as desktop holders for calendars with advertisements.

It is a top view of the expansion state of the envelope of one embodiment of the present invention. It is a figure explaining the procedure which assembles an envelope from the expansion | deployment state of FIG. It is a figure explaining the procedure which assembles a stand from the expansion | deployment state of FIG.

  Hereinafter, an embodiment of the envelope of the present invention will be described in more detail with reference to the accompanying drawings. As shown in FIG. 1, the envelope 1 of the present invention can be unfolded, that is, the envelope has no adhesive allowance such as an adhesive. The material of the envelope is not particularly limited, but can usually be paper, paperboard, plastic or the like. Preferably, it is light paper or plastic that does not take up weight when mailed. The deployed face is usually homogeneous, but may be reinforced such as thickening or duplicating part of it.

  In order to make it possible to assemble the envelope 2 and the stand 2 from the unfolded state, each part of the envelope is responsible for various functions as an envelope and a stand, as will be described below. First, the envelope 1 has a ceiling 10 as a space for storing the contents X. The ceiling 10 has a first reference line 11 that crosses the central portion thereof. This reference line becomes a broken line when the stand 2 is formed, and functions as a stand corner after bending. The first reference line 11 may be folded in advance, or only a mark such as a dotted line or an alternate long and short dash line may be provided as a guide when folding later.

  The upper stage 13 from the first reference line of the ceiling is in close contact with the lower stage 34 from the second reference line of the folded portion when the stand 2 is formed, thereby forming a front face 62 of a triangular prism. Therefore, the vertical width B above the first reference line of the top surface coincides with the vertical width B 'below the second reference line of the folded portion.

  Above the ceiling 10, the tongue 20 extends over the entire top. The bellows unit 20 has a function of sealing the folded portion 30 from above in the envelope 1 and a function of forming the back surface 61 of the triangular prism in the stand 2. The shape of the tongue may be rectangular, trapezoidal, elliptical, or indefinite.

  Since the tongue portion 20 overlaps the upper stage 33 from the second reference line of the folded portion when the stand is formed, the maximum vertical width A of the tongue portion matches the vertical width A 'of the upper portion from the second reference line of the folded portion.

  An engagement piece 21 protrudes near the center of the upper end of the tongue 20. The engagement piece 21 is inserted into a first incision portion 12 provided at the lower end of the ceiling 10 in the envelope 1 (becomes a boundary between the ceiling and the folded portion) and seals the envelope, and the stand 2. 2 and the function of fixing the shape of the triangular prism 60 by being inserted into the second incision 32 provided in the center of the folded portion 30.

  A folded portion 30 extends below the ceiling 10. Since the folded portion functions as the back surface of the envelope 1, the vertical width (the sum of A ′ and B ′) of the folded portion 30 is the same as or slightly shorter than the vertical width (the sum of B ′ and C) of the ceiling 10. .

  A second reference line 31 crosses the center of the folded portion 30. The position of the second reference line is usually approximately the center of the folded portion 30, but may be shifted from the center. In order to form the triangular prism 60 in close contact, the vertical width A ′ above the second reference line of the folded portion is made to coincide with the maximum vertical width A of the tongue portion, and the vertical length below the second reference line of the folded portion The width B ′ is made to coincide with the vertical width B above the first reference line of the top and bottom. The second reference line 31 may be folded in advance, or only a mark such as a dotted line or an alternate long and short dash line may be provided for later folding.

  The left and right guide pieces 40 and 50 extend on the left and right sides of the ceiling 10 and on the extension of the first reference line 11 (that is, the reference line covers). The left and right guide pieces serve both as a weir for preventing the contents X from jumping out to the left and right sides in the envelope 1 and as a guide pocket for inserting the contents X in the stand 2. Further, the left and right guide pieces double the corners of the front face 62 and the bottom face 63 of the triangular prism of the stand 2, and this duplication helps to stabilize the stand and enhance protection.

  The shape of the left and right guide pieces 40, 50 is not particularly limited. Preferably, when the upper steps 41 and 51 from the first reference line of the left and right guide pieces are substantially triangular as shown in FIG. 1, it is easy to insert the contents X such as a calendar into the stand 2 and the strength of the stand is further improved. It is effective in preventing the pocket from rising.

  The lower stages 42 and 52 from the first reference line of the left and right guide pieces 40 and 50 extend substantially over the entire lower stage from the first reference line of the ceiling as shown in the drawing in order to further strengthen the bottom of the triangular prism of the stand 2. A rectangular shape is preferred. If the thickness of the left and right guide pieces 40, 50, especially the lower steps 42, 52 from the first reference line is made thicker than the ceiling, the center of gravity of the stand is further stabilized.

  The surface of the lower steps 42 and 52 below the first reference line of the left and right guide pieces may be subjected to a non-slip process (not shown) such as attaching silicone rubber. This processing serves to prevent the grounding surface of the assembled stand 2 from slipping and helps to further stabilize the stand.

  A first incision 12 is provided at a position corresponding to a position directly below the engagement piece 21 at the boundary between the ceiling 10 and the folded portion 30. The first incision has a function of fixing the shape by inserting an engagement piece when the stand 2 is assembled. Therefore, the length of the first incision 12 is larger than the engagement piece 21.

  A second incision 32 is provided on the second reference line 31 and immediately below the engagement piece 21. The second incision portion has a function of sealing the envelope by inserting the engagement piece 21 when the envelope 1 is assembled. Therefore, the length of the second incision 12 is larger than the engagement piece 21.

  The shape of the cross section of the triangular prism 60 formed by being folded so as to wrap the ceiling surface 10, the bellows portion 20, and the folded-back portion 30 may be any of an equilateral triangle, an isosceles triangle, a right triangle, and an unequal triangle. The sandwiching angle D between the front surface 62 and the bottom surface 63 of the triangular prism means the elevation angle of the content X supported by the stand, and is therefore important from the viewpoint of the supportability and visibility of the content X. The angle D may normally be 45 to 90 °, and is preferably in the range of 50 to 80 °. The included angle E between the front surface 62 and the back surface of the triangular prism is important in that the content X is supported. The angle E may usually be 30 to 60 °, preferably 30 to 45 °. The maximum vertical width A of the bellows part and the second reference line of the folded part are set so that the included angle D between the front and bottom surfaces of the triangular prism and the included angle E between the front and back surfaces of the triangular prism satisfy the above angle range, respectively. A vertical width A ′, a vertical width B above the first reference line of the ceiling, a vertical width B ′ below the second reference line of the folded portion, and a vertical width C below the first reference line of the ceiling. The ratio is determined.

  Next, a method of forming an envelope from the expanded state of the envelope 1 will be described with reference to FIG. First, the left and right guide pieces 40 and 50 are folded back on the ceiling 10. Thereby, the left and right sides of the envelope are sealed. Next, the folded portion 30 is folded back on the folded left and right guide pieces. This seals the bottom of the envelope. As appropriate, after the contents X are inserted into the envelope 1, the tongue 20 is folded over the folded back 30. Thereby, the upper side of the envelope 1 is sealed. Finally, the engaging piece 21 protruding from the tongue 20 is inserted into the second incision 32. Thus, the envelope is completely sealed.

  Next, a method of forming the stand from the expanded state of the envelope will be described with reference to FIG. First, the left and right guide pieces 40 and 50 are folded back on the ceiling 10 as in the envelope forming method. The folded portion 30 is folded back from the second reference line 31 on the side opposite to the folded left and right guide pieces (that is, the back side of the ceiling). As a result, the triangular prism 60 is formed in such a manner that the bottom of the folded portion 30 hits the first reference line of the ceiling from the back side. At this time, the upper stage 33 above the second reference line forms the back surface 61 of the triangular prism.

  Next, the triangular column 60 is folded back from the first reference line 11 to the upper stage 13 and the velvet part 20 from the first reference line of the top and bottom on the triangular prism. Thereby, the upper stage 13 from the first reference line of the ceiling is in close contact with the lower stage 34 from the second reference line of the folded portion, and the front face 62 of the triangular prism of the stand 2 is reinforced. On the other hand, the tongue portion 20 is in close contact with the upper stage 33 from the second reference line of the folded portion, and reinforces the back surface 61 of the triangular prism.

  Finally, the triangular prism is fixed by inserting the engaging piece 21 into the first incision 12. Thereby, the stand 2 which consists of a triangular prism is completed. The contents X such as a calendar are inserted into the pockets formed in the front left and right corner portions 64 and 65 of the completed stand 2 to provide various uses such as a desktop calendar.

  As described above, the stand 2 can be easily assembled. However, if the method of deforming the envelope from the expanded state to the stand 2 is described on the envelope, for example, the inner surface of the expanded state, the stand 2 can be further facilitated. Can be assembled into.

  The use of the envelope and the stand of the present invention depends on the contents X enclosed in the envelope. The contents X are not particularly limited as long as the contents X are planes having a thickness capable of ensuring self-supporting properties. The contents X may be inserted into the pockets of the corner portions 64 and 65 of the stand 2 in the expanded state or the folded state as they are.

  Specific examples of the contents X include a calendar, a message card (Christmas card, birthday celebration, etc.), a postcard, a painting, a commemorative photo, and a bromide. In particular, if the envelope contents are a monthly calendar, a stand assembled from the envelope can be conveniently used as a monthly calendar.
