Description

  The present invention relates to a zipper slider unit, and more particularly to a zipper slider unit and a sealing bag having different opening / closing tensile forces.

  Currently, in the field of sealed bags, it is common to open or close the male and female zippers of the zipper by providing pressure, but in conventional sealed bags, the force used for opening and closing is the same For this reason, it has not been possible to determine whether the moving direction of the slider is the zipper opening direction or the closing direction. Especially in the field of packaging that is industrially automatically produced, if the force used for opening and closing is the same, the automation equipment cannot determine whether the sealed bag is in the open state or the closed state, Trouble occurred in the packaging process.

  The present invention provides a zipper slider unit and a sealing bag that have different pulling forces when opened and closed so as to address the deficiencies in the prior art described above.

  The technical solution in which the present invention solves the above technical problem is as follows. The zipper slider unit having different opening / closing tensile forces includes a male zipper, a female zipper, and a slider for opening or closing the zipper, the female zipper includes a female zipper body, and the male zipper includes a male zipper body. In the zipper slider unit, a plurality of recesses are provided symmetrically in the female zipper body and the male zipper body, and an angle α formed between the A surface of the recess and the horizontal line of the zipper is the B surface of the recess and the zipper The slider is smaller than an angle β formed by a horizontal line, and the slider includes a side plate, an open triangular block, and a closed triangular prism.

  Sealed bags having different opening and closing tensile forces include a bag body, and the zipper slider unit described above is provided in the opening of the bag body.

  The beneficial effect of the present invention is that in the present invention, a recess is provided on the outside or inside of the zipper, and the magnitude of the resistance between the open triangular block or the closed triangular prism in the slider and the recess is used, thereby making the process of use It is possible to determine whether the moving direction of the slider is to open or close the sealing bag, and to better understand the usage status of the sealing bag. If this type of sealed bag is applied to industrially automatically produced packaging, the automation equipment can determine whether the sealed bag is in an open state or a closed state, depending on the force it uses, and the efficiency of product packaging And quality improvement.

  Based on the above technical proposal, the present invention may be improved as follows.

  Further, the recess is provided on the outside of the zipper, an angle α ′ formed between the C surface of the closed triangular prism and the horizontal line of the zipper is equal to the angle α, and the D surface of the closed triangular prism and the horizontal line of the zipper are The formed angle γ is made larger than the angle β.

  The beneficial effect of adopting this improved scheme is that when opening the zipper, the angle α ′ and the angle α are equal, which reduces the resistance between the closed triangular prism and the recess and makes it easier to open the zipper. However, when the force used is small and the angle γ is larger than the angle β when closing the zipper, the resistance between the closed triangular prism and the dent increases, and a greater effect is required to close the zipper. It is to become.

  Further, the recess is provided inside the zipper, an angle α ″ formed by the E surface of the open triangular block and the horizontal line of the zipper is equal to the angle α, and the F surface of the open triangular block and the zipper The angle γ ′ formed with the horizontal line is made larger than the angle β.

  The beneficial effect of adopting the improved scheme described above is that when opening the zipper, the angle α ″ and the angle α are equal, reducing the resistance between the open triangular block and the recess, When opening the zipper and reducing the force used, and closing the zipper, the angle γ 'is larger than the angle β, which increases the resistance between the open triangular block and the recess, and closes the zipper The greater effect is required.

  Next, the principles and features of the present invention will be described in association with actual examples. The examples given are only used to understand the invention and are not intended to limit the scope of the invention.

Example 1
The zipper slider unit having different opening / closing tensile forces includes a male zipper, a female zipper, and a slider 1 that opens or closes the zipper. The female zipper includes a female zipper body 2. including. In the zipper slider unit, a plurality of recesses 4 are provided symmetrically in the female zipper main body 2 and the male zipper main body 3, and an angle α formed between the A surface 5 of the recess 4 and the horizontal line of the zipper The slider 1 is characterized in that it includes a side plate 7, an open triangular block 8, and a closed triangular prism 9, which is smaller than an angle β formed by the B surface 6 and the horizontal line of the zipper.

  The recess 4 is provided on the outside of the zipper, the angle α ′ formed between the C surface 10 of the closed triangular prism 9 and the horizontal line of the zipper is equal to the angle α, and the D surface 11 of the closed triangular prism 9 and the zipper The angle γ formed with the horizontal line is made larger than the angle β.

  The present invention is used as follows. When the zipper is opened, the fact that the angle α ′ and the angle α are equal reduces the resistance between the closed triangular prism and the recess, makes the zipper easier to open, and reduces the force used. When closing the zipper, since the angle γ is larger than the angle β, the resistance between the closed triangular prism and the recess is increased, and a larger action is required to close the zipper.

Example 2
The zipper slider unit having different opening / closing tensile forces includes a male zipper, a female zipper, and a slider 1 that opens or closes the zipper. The female zipper includes a female zipper body 2. including. In the zipper slider unit, a plurality of recesses 4 are provided symmetrically in the female zipper main body 2 and the male zipper main body 3, and an angle α formed between the A surface 5 of the recess 4 and the horizontal line of the zipper It is characterized by being smaller than an angle β formed by the B surface 6 and the horizontal line of the zipper, and the slider 1 includes a side plate 7, an open triangular block 8, and a closed triangular prism 9.

  The recess 4 is provided inside the zipper, an angle α ″ formed by the E surface 12 of the open triangular block 8 and the horizontal line of the zipper is equal to the angle α, and the F surface 13 of the open triangular block 8 An angle γ ′ formed with the horizontal line of the zipper is made larger than the angle β.

  The present invention is used as follows. When the zipper is opened, the fact that the angle α ″ is equal to the angle α reduces the resistance between the open triangular block and the recess, facilitates opening of the zipper, and reduces the force used. When closing the zipper, since the angle γ ′ is larger than the angle β, the resistance between the open triangular block and the recess is increased, and a larger action is required to close the zipper.

  The above descriptions are merely preferred embodiments of the present invention, and do not limit the present invention. All modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be equally included in the protection scope of the present invention.
