(10) Therefore, the embodiments described in the specification and shown in the drawings are purely illustrative and are not intended to represent all aspects of the present disclosure, such that various equivalents and modifications may be made without departing from the spirit of the present disclosure.

(11) That is, the easy-to-open gunny sack according to the present disclosure may allow a clip tape 20 to cover at least one of upper and lower ends of the sack portion, may allow a single-thread sewing portion 10 by single thread sewing to be formed around the covered portion, may allow an extended clip tape portion 21 formed by extension of the clip tape 20 to be formed at both sides of the single-thread sewing portion 10, and may allow an anti-loosening means and an opening identification means to be provided at the extended clip tape portion 21 of the end portion placed in the sewing proceeding direction.

(12) In the meantime, according to the embodiment of the present disclosure, the extended clip tape portion 21 may be comprised of three or more stitches formed by single thread sewing.

(13) According to the embodiment of the present disclosure, the anti-loosening means may be formed by injecting an adhesive into the last stitch of the single-thread sewing portion 10.

(14) According to the embodiment of the present disclosure, the anti-loosening means may be implemented by an anti-loosening tape 31. In more detail, a loop portion 11 of the last stitch of the single-thread sewing portion 10 is bonded to a bottom surface of the sewn section of the extended clip tape portion 21, resulting in formation of the anti-loosening tape 31 bonded to the extended clip tape portion 21. As a result, the anti-loosening tape 31 may serve as the anti-loosening means.

(15) Meanwhile, according to the embodiment of the present disclosure, the opening identification means may be implemented by the opening identification tape 32 for enabling the user to easily identify the end portion of the single-thread sewing portion 10. In more detail, the end portion 12 of the sewn section of the single-thread sewing portion 10 is bonded to a top surface of the sewn section of the extended clip tape portion 21, resulting in formation of the opening identification tape 32 attached to the extended clip tape portion 21. As a result, the opening identification tape 32 may serve as the opening identification means.

(16) According to the embodiment of the present disclosure, the opening identification tape 32 may be formed to protrude outward from the extended clip tape portion 21.

(17) According to the embodiment of the present disclosure, the opening identification tape 32 may be formed to have any distinctive color and/or may be formed of fluorescent materials, such that the user can easily identify the opening identification tape 32.

(18) According to the embodiment of the present disclosure, the anti-loosening tape 31 and the opening identification tape 32 may be integrated with each other, such that the outer surface of the end portion of the extended clip tape portion 21 is bonded while being covered with the integrated structure of the tapes 31 and 32.

(19) In addition, a sewing-sealing tape 40 may be provided to any one of both outer surfaces of the clip tape 20 including the single-thread sewing portion 10. In more detail, the sewing-sealing tape 40 formed at any one of both outer surfaces of the clip tape 20 may seal a sewing hole formed by penetration of a sewing needle, and may enable the sewing thread to be press-fitted into the sewing hole.

(20) The sewing-sealing tape 40 may be implemented by the gunny sack that is formed of a high-density paper or a synthetic resin sheet.

(21) A method for implementing the easy-to-open gunny sack according to the present disclosure will hereinafter be described with reference to the attached drawings.

(22) As described above, the above-mentioned easy-to-open gunny sack may allow the clip tape 20 to cover at least one of upper and lower ends of the sack portion, may allow the single-thread sewing portion 10 sewn by single thread sewing to be formed around the covered portion, may allow the extended clip tape portion 21 formed by extension of the clip tape 20 to be formed at both sides of the single-thread sewing portion 10, and may allow the anti-loosening means to be provided at the extended clip tape portion 21 of the end portion placed in the sewing proceeding direction. As a result, the sealed state of the sewing portion of the easy-to-open gunny sack may not be easily released by external impact. In addition, the sewing portion of the easy-to-open gunny sack is implemented by single thread sewing, such that the costs of sewing the gunny sack can be minimized.

(23) Meanwhile, according to the embodiment of the present disclosure, if the extended clip tape portion 21 is implemented by three or more stitches formed by single thread sewing of the single-thread sewing portion 10, the sewing thread of the single-thread sewing portion 10 can be kept at the sufficient amount of tensile force in response to the opening force generated from the center portion of the gunny sack. As a result, the sealed state of the gunny sack can be stably and firmly maintained.

(24) According to the embodiment of the present disclosure, if the anti-loosening means is implemented by injecting the adhesive into the last stitch of the single-thread sewing portion 100, the sewing thread of the last stitch of the single-thread sewing portion 10 is firmly sewn to the extended clip tape portion 21 located around the last stitch, such that the sewing thread of the gunny sack is prevented from being easily loosened by external impact.

(25) According to the embodiment of the present disclosure, the anti-loosening means may be implemented by the anti-loosening tape 31. In more detail, the loop portion 11 of the last stitch of the single-thread sewing portion 10 is bonded to the bottom surface of the sewn section of the extended clip tape portion 21, resulting in formation of the anti-loosening tape 31 bonded to the extended clip tape portion 21. Thus, the anti-loosening tape 31 may serve as the anti-loosening means. By the anti-loosening tape 31, the loop portion 11 exposed from the last stitch of the single-thread sewing portion 10 is bonded to the end portion of the sewing portion, such that the sewn state of the last stitch can be firmly maintained and loosening of the sewn state of the last stitch can be prevented.

(26) According to the embodiment of the present disclosure, the opening identification means may be implemented by the opening identification tape 32 for enabling the user to easily identify the end portion of the single-thread sewing portion 10. In more detail, the end portion 12 of the sewn section of the single-thread sewing portion 10 is bonded to a top surface of the sewn section of the extended clip tape portion 21, resulting in formation of the opening identification tape 32 attached to the extended clip tape portion 21. Thus, the opening identification tape 32 may serve as the opening identification means. In the situation in which the opening identification tape 32 is formed to protrude outward from the extended clip tape 21, the user can easily grasp the opening identification tape 32 in the process of opening the gunny sack, and can thus open the gunny sack using the opening identification tape 32.

(27) In addition, according to the embodiment of the present disclosure, in the situation in which the opening identification tape 32 is formed to have any distinctive color capable of being easily identified by the user, the user can easily identify the opening identification tape 32 in the process of opening the gunny sack, and can thus open the gunny sack.

(28) Meanwhile, according to the embodiment of the present disclosure, in the situation in which the sewing-sealing tape 40 is provided to any one of both outer surfaces of the clip tape 20 including the single-thread sewing portion 10, not only the sewing thread needed for the sewing process, but also the sewing-sealing tape 40 forcibly moves toward the sewing hole. In more detail, the sewing-sealing tape 40 may seal the sewing hole formed by penetration of the sewing needle, and may enable the sewing thread to be press-fitted into the sewing hole. As a result, content stored in the gunny sack can be prevented from leaking outside through the sewing hole, the sewing thread is firmly press-fitted into the sewing hole, and the sewn state of the gunny sack can be firmly kept at high tensile force.
