Description

  The present invention relates to a convenient sealing material capable of performing an opening operation.

  As a conventional sealing material, a sheet body in which an adhesive film is formed at both ends along the longitudinal direction, and a separator that is detachably bonded to the adhesive film at both ends of the sheet body are provided. The thing which has arrange | positioned the pick piece of a means is known (for example, refer patent document 1).

JP 2000-72175 A (page 2-4, FIG. 3)

  However, in the conventional sealing material, when the knob is pulled, the sheet body is simply torn and is not tasted. Accordingly, an object of the present invention is to provide a sealing material capable of performing an opening operation by utilizing the fraying phenomenon of a double ring stitch.

  In order to achieve the above object, the present invention comprises a sheet body in which an adhesive film is formed at both ends along the longitudinal direction, and a separator that is detachably bonded to the adhesive film at both ends of the sheet body. In the sealing material in which the picking piece of the unsealing means is arranged in the non-adhesive part, the sheet body is divided into two parts in the non-adhesive part and superimposed on the top and bottom, and a double ring seam is formed in the overlapped part. The looper thread remaining at the end of the seam is used as a knob for the opening means.

  In addition, it is advisable to attach the separators separately to the adhesive films at both ends of the sheet body, and to arrange the looper thread part rows of double ring stitches side by side with the separators. It should be narrower than the left and right width of the seam. Alternatively, the separator may be bonded to the adhesive films at both ends of the sheet body, and the needle thread portion rows of double ring stitches may be provided side by side with the separator.

  Further, the adhesive film of the sheet body is formed on either the left or right side of the looper thread part row and the needle thread part row of the double ring stitch, and the separator that is detachably bonded to the adhesive film is formed on the other non-adhesive part It may be adjacent to the side.

  According to the present invention, when the knob piece is pulled, the looper thread portion row of the double ring stitches is successively frayed, so that the sheet body can be easily divided into two while enjoying the shortness of the double ring stitches. Can be opened. If the adhesive film of the sheet body is formed on the left and right along the looper thread part row of the double ring stitch, only the double ring stitch can be emphasized at the time of sealing. If the width of the double chain stitch is narrower than the left and right width, the double chain stitch will not be hooked when sealed.

  Further, if the adhesive film of the sheet body is formed on the left and right along the needle thread portion row of the double ring stitch, the sealing operation is facilitated. The adhesive film of the sheet body is formed on either the left or right side of the looper thread part row and the needle thread part row of the double ring stitch, and the separator that is detachably bonded to the adhesive film is placed sideways with the other non-adhesive part. If it is made to adjoin to the direction, the thickness as a sealing material can be made substantially constant.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view showing an embodiment of a sealing material according to the present invention. As shown in FIG. 1, the sheet bodies 2 and 2 of the sealing material 1 are divided into two parts and overlapped vertically, and this overlapped part (non-adhesive part) is sewn by a double ring stitch S. It has become. The double chain stitch S is formed by a known multi-needle double chain stitch sewing machine, and the looper thread 7 at the end of the double chain stitch S is left slightly longer. On the sheet bodies 2 and 2, adhesive films 3 and 3 are formed along the longitudinal direction. The adhesive films 3 and 3 are arranged on the left and right adjacent to the looper thread portion row 7LL of the double ring stitch S, and the separators 4 and 4 are bonded to the adhesive films 3 and 3, respectively. The separators 4 and 4 are detachable from the adhesive films 3 and 3.

  A usage example of the sealing material 1 will be described with reference to FIGS. 2 and 3. When sealing the envelope 5, one separator 4 is first peeled off from the adhesive film 3, and the adhesive film 3 is pressure-bonded to the surface 6 a of the lid piece 6 of the envelope 5. The left and right width of the pressure-sensitive adhesive film 3 serving as the pressure-bonding portion is narrower than the left and right width of the double ring stitch S, so that the double ring stitch S does not have a hook shape when sealed. Then, after the lid piece 6 is bent toward the sealing portion 5 a side of the envelope 5, the other separator 4 is peeled off from the adhesive film 3, and the envelope 5 is closed. Note that the looper thread 7 at the end of the double seam S may be held on the envelope with a seal or the like so as not to interfere with the opening.

  When unsealing, the looper thread 7 (the knob of the unsealing means) remaining at the end of the double chain stitch S may be pulled. As shown in FIG. 4, when the looper thread 7 is pulled in the arrow direction X, the last looper thread loop 7L is disengaged from the needle thread loops 9L and 9L, and the front looper thread loop 7L 'becomes free. When the looper thread 7 is further pulled, the looper thread loop 7L 'is disengaged from the front needle thread loops 9L' and 9L '. That is, by pulling the end looper thread 7, the double chain stitches S are successively frayed. The overlapped sheet bodies 2 and 2 are substantially separated when the double ring stitch S is frayed, and can be easily opened as shown by a one-dot chain line in FIG.

  In the sealing material 1 (first embodiment), the adhesive film of the sheet body is formed on the left and right along the looper thread portion row 7LL of the double ring stitch, but is not limited thereto. For example, like the sealing material 10 shown in FIG. 5, the adhesive films 11 and 11 of the sheet bodies 2 and 2 may be formed on the left and right along the needle thread portion row 9LL of the double ring stitch S. At that time, the separators 12 and 12 may be bonded to the adhesive films 11 and 11 separately. As shown in FIG. 6, the sealing material 10 can be easily sealed even after the lid piece 6 is bent toward the sealing portion 5 a side of the envelope 5.

  In the sealing material 10 (second embodiment), the pressure-sensitive adhesive film is pressure-bonded by the surface 6a of the lid piece and the sealing portion 5a of the envelope. The back surface 6b and the envelope sealing portion 5a may be used. With this configuration, the sealing material 10 can be concealed within the lid piece 6 of the envelope 5. In addition, as the double ring stitch S of the sealing material 10, the stitch type display symbol 406 shown in JIS L 0120 is adopted, but the present invention is not limited to this. For example, as shown in FIG. A display symbol 401 in a stitch format may be used. By adopting the stitch format 401, not only the sealing material can be concealed but also the impression of the sealing material can be diluted.

  Furthermore, in both embodiments, an adhesive film is formed on one side of the sealing material, but the present invention is not limited to this. As shown in FIG. 8, the adhesive films 14 and 14 of the sheet bodies 2 and 2 are respectively formed on either the left or right side of the looper thread portion row 7LL and the needle thread portion row 9LL of the double ring stitch S, and The separators 15 and 15 that are detachably bonded to the adhesive films 14 and 14 may be laterally adjacent to the other non-adhesive portion. With such a configuration, the thickness of the sealing material 13 can be made substantially constant. As an example of use of the sealing material 13, there is a form as shown in FIG. 9 and FIG. As a modification of the sealing material 13, a seam allowance portion may be provided on the left and right along the looper thread portion row 7LL of the double ring stitch S, and the seam allowance portion may be decorated.

  In the present embodiment, the sealing material is used for sealing the envelope, but is not limited thereto. For example, the present invention can also be applied to sealing a packaging for goods used in a card market, a bookbinding market, or a wine market.
