Description

  The present invention relates to a bag body with a synthetic resin chuck that can easily and reliably bite a male and female bite type chuck provided in an opening of a bag.

  As shown in FIG. 6, in a synthetic resin packaging bag made of front and back body film 2 a, 2 b, a bag 1 with a synthetic resin chuck, in which a male and female bite type chuck 5 is provided inside the opening 3. (Hereinafter referred to as a bag) is well known. In this bag body, in order to occlude the chuck 5 and close the opening 3, an operation of pressing the back surface of the chuck 5 with the finger pad and sliding it in the longitudinal direction of the chuck 5 is generally performed.

  However, when the finger pad is squeezed with the finger pad over the entire width of the chuck 5 and the finger pad is slid along the back line, for example, when the hand is wet and easily slips, the finger pad is the chuck 5. Deviating from the back line of the chuck 5, the occlusion of the chuck 5 becomes incomplete. In this case, the sliding operation is performed by pinching the back position of the chuck 5 in the vicinity where the finger pad part deviates from the back line of the chuck 5 with the finger pad part again.

  In addition, the finger pad does not deviate from the back line of the chuck 5, but when it is about to deviate, the chuck 5 is engaged by repeating so-called meandering while correcting the position of the finger pad to the back of the chuck 5.

As described above, the conventional bag body with a synthetic resin chuck has a problem of so-called chucking, and this problem is caused by the thin body films 2a and 2b on the front and back of the thin chuck 5 having a long overall width and weak waist. In this case, it has been a problem to make the chucking easily and reliably.

  According to the present invention, the finger pad portion that presses the back surface of the chuck with the fingertip is prevented from deviating from the back surface line of the chuck by the weir-like band provided in parallel with the chuck, and is guided and regulated along the back surface line of the chuck. Therefore, there is an effect that the so-called chucking is easily and reliably performed.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. In FIG. 1, which is a cross-sectional view of the main part in a state where the bag body is turned sideways, 1 is a bag body (hereinafter referred to as a bag body) with a synthetic resin chuck. In this bag body 1, a male / female occlusal chuck 5 made of synthetic resin is provided so as to face the inside of an opening 3 of a synthetic resin packaging bag made of front and back body films 2 a and 2 b. Reference numeral 4 indicates the inside of the bag.

  According to the present invention, when the back surface of the chuck 5 is clamped by the finger pad portion and slid in the longitudinal direction of the chuck 5 to engage the chuck 5, the finger pad portion deviates from the back line of the chuck 5. This is characterized in that a weir-like band that prevents this and guides and regulates along the back line of the chuck 5 is provided in the vicinity of the chuck 5 in parallel with the chuck 5.

  When the back surface of the chuck 5 is clamped by the finger pad portion and slid in the longitudinal direction of the chuck 5 to engage the chuck 5, the finger pad portion is prevented from deviating from the back line of the chuck 5, and the back surface line of the chuck 5 is prevented. A specific embodiment in which a dam-like band for guiding and regulating along the chuck 5 is provided in parallel with the chuck 5 will be described. As shown in FIG. 1, weirs 6a, 6b, 7a and 7b are provided facing the opening 3 side and the bag inner side 4 on the inner surfaces of the front and back body films 2a and 2b with the chuck 5 in the center. Structure.

  The weir-like bands 6a, 6b, 7a, 7b are preferably provided at positions separated from the center of the chuck 5 by about 6-8 m / m. Further, the cross-sectional shapes of the dam-like bands 6a, 6b, 7a, 7b are such that the finger pad portion sandwiching the back surface of the chuck 5 prevents the deviation from the back line of the chuck 5 by the dam-like bands 6a, 6b, 7a, 7b. Therefore, squares, rectangles, trapezoids, circles, ellipses, etc. are suitable. The area of this cross section is preferably about 1 to 2 mm2. Further, the thickness of the weir strips 6a, 6b, 7a, 7b that are in contact with each other is suitably equivalent to the thickness of the chuck 5 that is engaged.

Contrast with FIG. 6 which illustrates a conventional example about the effect of this invention which consists of said structure,
This will be described with reference to FIGS. As shown in FIG. 6, conventionally, in order to close (engage) the chuck 5 of the opening 3, for example, the male and female claws of the chuck 5 are engaged with each other while the back surface of the chuck 5 is clamped between the index finger and the finger pad of the thumb. It is necessary to slide the finger pad part continuously in parallel with the chuck 5 in the longitudinal direction. However, in the conventional type bag, even if the finger pad portion is slid along the back surface of the chuck 5, the finger pad portion does not move due to the convex structure of the chuck 5 and the slip properties of the front and back body films 2a and 2b. It was difficult to smoothly chuck the chuck 5 by meandering or derailing the back surface of the chuck 5 in the vertical direction.

  Therefore, in order to solve this conventional problem, in the present invention, weir-like bands 6a, 6b, 7a, and 7b are provided above and below the chuck 5 as the center. As shown in FIG. 3, in a hand with a small and thin fingertip, when the back surface of the chuck 5 is clamped between the index finger and the finger pad portion of the thumb, the finger pad portion is formed between the chuck 5 and the weir-like bands 6a, 6b, 7a, 7b. It is difficult to press the whole. In this state, when the finger escapes upward in the process of moving the finger pad part in parallel with the chuck 5, the finger pad part enters the recess 8 between the chuck 5 and the dam-like bands 6a, 6b. And slide in parallel with the chuck 5 while being sandwiched between the weir-like bands 6a and 6b. Conversely, when the finger escapes downward, the finger pad portion enters the lower recess 9 and slides while moving parallel to the chuck 5 while being sandwiched between the chuck 5 and the weir-like bands 7a and 7b. That is, the finger pad portion is blocked by the dam-like bands 6a, 6b, 7a, 7b even if it deviates upward or downward from the back line of the chuck 5. As a result, the finger pad portion is guided and restricted by the recess 8 or 9, and the chuck 5 It is possible to easily and reliably perform chucking (occlusion) by sliding along the back surface line.

  As shown in FIG. 4, in a thick type hand with a large fingertip, the back surface of the chuck 5 is clamped by the finger pad portion so that the chuck 5 is in the center and between the chuck 5 and the weir-like bands 6a, 6b, 7a, 7b. A part of the finger pad part where the recesses 8 and 9 are formed and the back surface of the chuck 5 is clamped enters the recesses 8 and 9, and the other part of the finger pad part presses the dam-like bands 6a, 6b, 7a and 7b. Then, a part of the finger pad portion that has entered the recesses 8 and 9 is sandwiched between the chuck 5 and the dam-like bands 6a, 6b, 7a, and 7b and is guided and regulated, and the dam-like bands 6a and 6b are further stabilized. , 7a and 7b prevent deviation from the back line of the chuck 5, and slide along the back line of the chuck 5 to engage (chuck) the chuck.

  In the above embodiment, the inner surface of the front and back body film 2a, 2b is provided with the chuck 5 in the center and the weir-shaped bands 6a, 6b, 7a, 7b facing the opening 3 side and the bag inner side 4 However, the dam-like bands 6a and 6b may be provided only on the opening 3 side, or the dam-like bands 7a and 7b may be provided only on the bag inner side 4.

  Furthermore, as shown in FIG. 5 as another embodiment, the dam-like bands 6 and 7 formed as a single piece have the chuck 5 at the center and either the opening part 3 side of the body film 2a or 2b on the front and back sides. You may provide in the bag inner side 4. FIG. Further, the dam-like band 6 may be provided only on the opening 3 side, or the dam-like band 7 may be provided only on the bag inner side 4. Furthermore, even if either one of the dam-like bands 6 and 7 or the dam-like bands 6 and 7 is provided on the outer surface of one or both of the front and back body film 2a and 2b, The deviation from the back line of the chuck 5 can be prevented, and the chuck 5 can be slid along the back line of the chuck 5 to be engaged (chucked).

  Further, the dam-like bands 6a, 6b, 7a, 7b may be thermally welded to the front and back body films 2a, 2b alone, or may be provided on the chuck tape or on a separate tape.

  As described above, according to the present invention, the finger pad portion sandwiching the back surface of the chuck 5 with the fingertip is prevented from deviating from the back surface line of the chuck 5 by the weir-like band provided in parallel with the chuck 5, and along the back surface line of the chuck 5. Therefore, it is possible to easily and surely perform chucking (occlusion), and has an advantage of solving the conventional problems.
