Description

  The present invention relates to an envelope having a structure that prevents an enclosure from being cut accidentally at the time of opening, and can be suitably used particularly for a BPO (Business Process Outsourcing) operation that requires opening a large amount of envelopes. Concerning envelopes.

  In general, envelopes are opened by cutting the tip of the envelope using scissors or a paper knife, or by tearing the envelope with a human hand, but the internal documents and letters are damaged when the envelope is opened. There was a problem. Various proposals have been made for this problem.

  For example, Patent Document 1 discloses an easy-opening means by perforations provided at a predetermined interval from a sealing-side bottom end folding line of an envelope, a sealing means in an envelope by emboss crimping, and a document movement limiting means. Is described. Patent Document 2 discloses a structure in which a perforation for opening is provided at an end (sealing side) opposite to the opening side of the envelope and a stopper having a predetermined width glued from the perforation toward the sealing side. It is described that.

  These conventional ones are supposed to be opened only by human hands, and although certain effects of solving the above problems are exhibited, they are still not sufficient. That is, when it is necessary to open a large amount of envelopes for BPO work or the like, the machine may cut three sides other than the opening side of the envelope by a machine. No means is provided, and there is a risk of accidentally cutting the inclusions by left and right cutting. Patent document 2 also does not correspond to the three-way cutting with a machine, and there is a possibility of cutting an inclusion by mistake. Moreover, since it is necessary to provide the stopper of the predetermined width | variety glued at the time of envelope manufacture, patent document 2 cannot be manufactured when the manufacturing equipment of an envelope is not held.

Japanese Patent No. 5442879 Utility model registration No. 3183554

  As described above, when opening an envelope with a machine as usual, the envelope is removed by cutting on three sides of the envelope, but if the envelope is close to the side to be cut, the envelope is cut. There was a case.

  The present invention provides not only a case where an envelope with an inclusion is opened by a human hand, but also an envelope that can be taken out without accidentally cutting the envelope when the envelope is opened by cutting by a machine. .

In the present invention, there is formed a restricted movement region of the inclusion by embossing crimping on the three sides consisting of the sealing side lower part and the left end part and the right end part of the envelope,
The movement restriction region is formed with a predetermined width that can maintain a pressure-bonding that does not peel off with a force sufficient to put the inclusion in the envelope ,
The present invention relates to an envelope for machine opening by a cutting machine, characterized in that at least one of the three sides is formed with an interval that can be opened by inserting a finger.

Further, the present invention provides a method for manufacturing an envelope for machine opening by a cutting machine, which forms a restricted movement region of an inclusion by embossing crimping on three sides including a sealing side lower part, a left end part, and a right end part of the envelope after bag making Because
The movement restriction region is formed with a predetermined width that can maintain a pressure-bonding that cannot be peeled off with a force sufficient to put the inclusion in the envelope ,
The present invention relates to a method for manufacturing an envelope for mechanical opening by a cutting machine, wherein at least one of the three sides is formed with an interval that can be opened by inserting a finger.

  According to the present invention, since the inclusion does not approach the three ends of the envelope, the three sides can be cut mechanically, and the inclusion can be taken out without being accidentally cut.

  Moreover, by providing the convex part and the part which has not processed anything, when cutting, a finger can be put in from the part which has not processed anything, and it can open easily. Also, by cutting the concavo-convex part, the concavo-convex part is adhered to the extent that the inclusion is retained even after cutting, so it is sealed in another envelope before the operator removes the inclusion by hand The sealed inclusions do not mix with each other.

  Furthermore, by matching the thickness of the movement-restricted region (the height of the unevenness) by the embossing with the thickness of the envelope in which the inclusion is enclosed, the envelopes can be cut without shifting when the envelopes are cut together.

  Moreover, since it can produce by processing a molded envelope, it can be produced easily even if it does not have an envelope manufacturing facility.

It is explanatory drawing which shows embodiment of the envelope of this invention. It is explanatory drawing for the convex-concave part of a movement restriction | limiting area | region. It is explanatory drawing of the cutting in the state which piled up several envelopes. It is explanatory drawing of the crimping | compression-bonding width | variety of a movement control area | region. It is explanatory drawing which shows another embodiment of the envelope of this invention.

  A configuration and an embodiment of an envelope having a structure for preventing an inclusion from being cut accidentally at the time of opening will be described with reference to the drawings.

  FIG. 1 is an explanatory view showing an embodiment of an envelope 1 of the present invention. The envelope 1 is formed with a restricted movement region of the inclusion in three sides including a lower part on the sealing side, a left end part, and a right end part. 2a is a convex part of the movement restricting area in the lower part on the sealing side, and 2b and 2c are the left end. The convex-concave part of the movement restriction | limiting area | region of a part and a right end part is shown.

  This movement restriction region is provided at a predetermined position by forming a portion (see FIG. 2) that is crimped in a convex and concave shape by a pressure roller or the like. The convex and concave portions provided on the three end sides other than the opening side of the envelope are pressure-bonded so as not to be peeled off with a force sufficient to put the inclusion in the envelope. However, since it is not bonded, it can be opened by removing the unevenness or peeling it with a strong force. That is, by using such an emboss crimping process, it can be easily opened after cutting, and a manufactured envelope can be easily processed.

  Further, as shown in FIG. 1, the movement restriction region is provided intermittently with the convex and concave portions. That is, the convex and concave portions and the portions where nothing is processed are alternately provided. Thereby, when cutting, a finger can be put in from an unprocessed part and can be easily opened. It should be noted that at least one of the above three directions is necessary for the alternating arrangement of the convex and concave portions and the portion where nothing is processed, and it is preferable to arrange the three sides alternately as shown in FIG.

  As shown in FIG. 2, it is preferable that the height of the convex / concave portion of the movement restriction region is approximately the same as the thickness of the envelope in which the inclusion is enclosed. By doing so, as shown in FIG. 3, when a plurality of envelopes are stacked and cut together, the envelopes can be cut without shifting.

  The width of the movement-restricted region or the pressure-bonding width can be appropriately determined within a range in which pressure-bonding that cannot be peeled off with a force sufficient to insert the inclusion into the envelope can be maintained and the size of the inclusion to be inserted is not significantly disturbed.

For example, when a B5 paper (257 mm × 182 mm) is folded into four (64.25 mm × 182 mm) into a standard envelope having the maximum size (120 mm × 235 mm), the maximum pressure bonding width is 120: 64.25 = 55.75mm
Bottom: 235-182 = 53mm
It becomes. Since the minimum crimping width is required to be at least 1 mm, in the envelope of a standard size, the side crimping width (A + B) shown in FIG. 4 is in the range of 1 to 55 mm, and the bottom crimping width (C) is in the range of 1 to 53 mm.

For non-standard envelopes, when the A4 paper (297 mm x 210 mm) is not folded into a square type 0 envelope (287 mm x 382 mm), the maximum crimp width is the side: 287-210 = 77 mm
Bottom: 382-297 = 85mm
Therefore, the side pressing width (A + B) is in the range of 1 to 77 mm, and the bottom pressing width (C) is in the range of 1 to 85 mm.

  As described above, the minimum crimping width is required to be at least 1 mm. However, considering error prevention when a plurality of envelopes are stacked and cut, the crimping width is preferably 3 mm or more.

  FIG. 5 is an explanatory view showing another embodiment of the envelope 1 of the present invention. The envelope 1 is formed with an inclusion movement restriction region on three sides of the left end portion, the right end portion, and the lower portion on the sealing side, and further, an opening notch 3 is formed obliquely at least in the vicinity of the left and right end portions of the lower portion on the sealing side. Has been. After cutting, the envelope can be opened by using the notch 3 as a trigger, and the inclusion can be easily taken out.

  In the embodiment shown in FIG. 5, after cutting, since the envelope can be easily opened from the notches 3 in the vicinity of the left and right ends of the lower part on the sealing side, both the left end part and the right end part and the sealing The convex and concave portions of the movement restriction region on the lower side may not be provided intermittently.

  The envelope may be made of any material as long as it can be uneven. Moreover, it can process any kind and size, and can process it after an envelope shaping | molding instead of the manufacturing process of an envelope.

  In addition, although this invention respond | corresponds to the three-way cutting by a machine, when opening with scissors, a cutter, etc. by a human hand, it is possible to take out an enclosure without cut | disconnecting. Moreover, the ease of opening by human hands may be enhanced by appropriately performing perforation.

  With respect to a commercially available standard envelope (120 mm × 235 mm), a movement restriction region as shown in FIG. 1 was formed by a pressure roller on three sides other than the opening side of the envelope. The side pressing width (A + B) shown in FIG. 4 was 15 mm, and the bottom pressing width (C) was 10 mm. Moreover, the height of the part (refer FIG. 2) crimped | bonded to the uneven shape is 0.75 mm.

  Next, B5 paper (257 mm × 182 mm) was folded into four (64.25 mm × 182 mm) and sealed in this product. The envelope thickness after sealing was 0.75 mm.

  The envelope containing the inclusions was cut using PK-513L manufactured by Plus Co., Ltd. on the three-way movement restriction region as shown in FIG. The cutting could be easily opened without damaging the inclusion.

  Further, in the same manner as described above, a plurality of envelopes containing the inclusions were prepared in the invention, stacked as shown in FIG. 3, and simultaneously cut by a machine. Since the envelopes do not shift even if they are stacked, there is no cutting error or damage to the inclusions, and it has been confirmed that they are suitable for BPO work.
