Description

  The present invention relates to a retrofit chuck slider that can be easily mounted mainly on a chuck mounted on an opening of a bag, and in particular, a chuck slider configured so that the mounted slider does not fall off the chuck. It is about.

  The chuck attached to the opening of a synthetic resin bag is called a so-called profile method, and includes a fitting portion composed of a pair of concave and convex rails, and the concave and convex rails are bonded to opposite positions inside the opening portion. is there. On the other hand, the slider facilitates opening and closing operations of the chuck, and a crimping body for fitting the chuck and an interrupting member for opening the chuck are arranged in a pair of side walls straddling the outside of the chuck. It is.

  These chucks and sliders are used as a set. However, it takes a lot of labor to mount the sliders on the chuck provided on the bag. That is, it takes a lot of labor to insert the interrupting member between the uneven rails of the chuck and to attach the outer side of the opening of the bag with the crimping body.

  Conventional sliders include a front-end type in which the slider is inserted and attached while the end of the chuck is open, and a retrofit type slider in which the slider is attached with the end of the chuck joined. Since the tip type slider needs to be mounted in the bag manufacturing process, there is a disadvantage that the manufacturing process becomes complicated. On the other hand, the retrofit type slider has the advantage that it can be attached to the finished bag at any time. However, the attachment work is performed by inserting an interrupting member between the uneven rails of the chuck and outside the opening of the bag. Therefore, there are disadvantages that the mounting work is troublesome and that the mounted slider is easily dropped during use.

  In view of this, Patent Document 1 discloses an opening / closing tool for a packaging bag with a chuck that can be easily mounted with a retrofit type slider. This opening / closing tool (slider) is designed to allow easy attachment of a retrofit type slider by providing one of the side walls of the slider that sandwiches the outside of the chuck so that it can be freely opened and closed.

  Also, Patent Document 2 describes a zipper (chuck) slider in which a part of a side wall sandwiching a chuck is provided so as to be freely opened and closed. This slider has a leg (crimped body) that clamps the chuck in the center of the side wall, and a wing body is formed so as to surround the leg. It is structured to be swingable.

Japanese Patent Laid-Open No. 2003-20050 Japanese Patent No. 3016654

  According to the slider described in Patent Document 1, it is possible to easily attach the slider to the chuck by opening and closing one of the side walls of the slider that sandwiches the chuck, but the other side wall is fixed. Therefore, the operation of inserting the opening edge of the bag into the fixed side wall is the same as before. As a result, it is difficult to mount the other chuck in the gap between the crimping body and the interrupting member in the other side wall.

  In addition, as in Patent Document 2, a leg portion that clamps a chuck is fixed to the central portion of the side wall, and a wing body is formed so as to surround the periphery of the leg portion, the leg portion provided in the central portion of the side wall And the separation finger (interrupting member) are fixed, the work of inserting a pair of chucks into the gap between the crimped body and the interrupting member in the leg is interrupted between the uneven rails of the chuck. This is a procedure for inserting the member and mounting the bag so that the outer side of the opening side edge of the bag is clamped by the crimping body, which is the same as the conventional mounting procedure.

  And in order to connect the side wall of patent document 1, and the wing body described in patent document 2 so that opening and closing is possible, the latching claw which engages a side wall and wing body is employ | adopted. However, when such a locking claw is employed in the slider, there is a possibility that a load is applied to the engaging claw each time the slider is reciprocated. That is, any of the engaging claws is provided so as to be engaged in a state orthogonal to the moving direction of the slider. Therefore, even if these engaging claws can exert a strong engaging force in this orthogonal direction, they are in a fragile state that is easily disengaged with respect to the moving direction of the slider.

  In particular, since the engaging claw of Patent Document 1 is provided on the upper part of the interrupt member, when the interrupt member that opens the chuck moves along the opening of the chuck, the sliding direction applied to the interrupt member The load is directly transmitted to the engaging claws. Such a load has a weak engagement force for the engaging claw, and therefore, the slider may come off when an unexpectedly strong load is applied to the engaging claw through the interrupting member.

  In addition, the retrofit type slider cannot be inserted and mounted with the chuck end open, unlike the front mount type, so it is necessary to forcefully spread the crimped body and sandwich the chuck when mounting. is there. This work is the same work in Patent Document 1 and Patent Document 2. Therefore, the crimping body in the retrofit type slider is configured to be easily opened. For this reason, when the crimping body reaches the heat-sealed portion at the end of the bag, the crimped body may open and exceed the heat-sealed portion.

  Therefore, when the conventional slider S reaches the end of the bag P, the interrupting member 100 is normally locked to the heat-sealed portion P2 of the opening P1, and the crimping body does not exceed the heat-sealed portion P2. Is configured to stop. However, as shown in FIG. 9, if the width of the heat-sealed portion P2 is narrow, even if the interrupting member 100 is locked to the heat-welded portion P2, a part of the slider S is detached from the chuck end, The slider will fall off.

  Therefore, when mounting a retrofit type slider, widen the width of the heat fusion part at the end of the chuck, or use a stop member with a thickness that does not exceed even if the crimped body opens. It was necessary to devise measures to prevent the slider from falling off, such as by providing it.

  Therefore, the present invention has been devised to solve the above-mentioned problems. In a retrofit type slider, the mounting work can be facilitated, and the fall during use can be prevented. An object of the present invention is to provide a chuck slider that is not restricted by a width or the like.

  In order to achieve the above-described object, the first means of the present invention is to attach the chuck Q to the chuck Q which is attached to the chuck Q provided in the opening P1 of the bag P in advance and to which the chuck Q is fitted. In the chuck slider in which the interrupting member 11 is disposed in a pair of side walls 20 straddling the outside of the chuck Q, the side walls 20 have connecting portions 23 on both sides of the fixed substrate 10 disposed on the top of the slider. The interrupting member 11 is provided on the lower surface of the fixed substrate 10, and the pressure-bonding body 21 is formed inside each side wall 20 to fix the side wall 20 to the lower surface of the fixed substrate 10.

  In the second means, the fitting convex portion 22 includes a protruding shaft portion 22A protruding from the inside of the side wall 20, and a locking rod 22B extending along the connecting portion 23 from the tip of the protruding shaft portion 22A. The fitting recess 12 is provided with a locking protrusion 12B that locks the locking rod 22B of the fitting protrusion 22, and a recessed protrusion at the center of the locking protrusion 12B. It is comprised by the shaft fitting recessed part 12A which fits the protrusion shaft part 22A of the part 22. FIG.

  In the third means, the stopper 13 protrudes from the lower surface of the fixed substrate 10 to the upper edge of the chuck Q, and the stopper 13 moves to the end of the chuck Q when the stopper 13 moves to the end of the chuck Q. It is formed so as to hit the inside of the P1 end.

  According to a fourth means, a reinforcing rib 14 is provided on the lower surface of the fixed substrate 10, the interrupting member 11 and the stopper 13 are provided on the reinforcing rib 14, and the fitting recess 12 is provided on the reinforcing rib 14. It is in having formed.
