Definitions

  • the present invention relates to a zipper bag and a slider, and more particularly to a bag which has, at the open side of the bag, a zipper composed of a concave portion and a convex portion which are capable of engaging with each other and a slider for opening and closing the zipper.
  • a bag 1 shown by Fig. 18a has, at the top end of a front film 2 and a back film 3, a zipper 4 composed of a concave portion 4a and a convex portion 4b, and this type of bag is called top-zipper type.
  • This top zipper is opened and closed by an opening/closing device (slider) 900 shown in Fig. 18a.
  • a bag 1 shown by Fig. 18b has a zipper 4 composed of a concave portion 4a and a convex portion 4b which are formed integrally with the front film 2 and with the back film 3, respectively, on their inner surfaces in the upper portion.
  • FIG. 18c has a zipper 4 made by fixing a concave portion 4a and a convex portion 4b on the inner surfaces of the front film 2 and the back film 3, respectively, in the upper portion.
  • the bags 1 shown by Figs. 18b, 18c and 18d are of a type which has flaps 2a and 3a of the films 2 and 3 above the zipper 4, and such a bag 1 is opened by picking the flaps 2a and 3a by fingers.
  • Fig. 19b shows a case that the opening/closing device (slider) 900 is fitted to the pseudo top-zipper bag 1.
  • the slider 900 is slid to the end to open the zipper 4, about a half of the slider 900 sticks out from the end of the bag 1, which is unstable.
  • the following countermeasures to avoid this problem have been taken: fitting a stopper at the end of the bag 1; and forming a projection on the end of the bag 1 by welding the end by use of a high-frequency welder and using the projection as a stopper of the slider 900.
  • the fitting of the stopper and the partial welding have been carried out by hand. This has caused problems of increasing the number of processes and accordingly of increasing the cost.
  • this slider 900 is apt to roll as indicated by arrow "a" in Fig. 19a, and the movement of the slider 900 is not so smooth.
  • the pseudo top-zipper bag shown by Figs. 18b and 18d still has short flaps 2a' and 3a' although the flaps 2a and 3a have been cut.
  • the ceiling of the slider 900 rubs against these short flaps 2a' and 3a', thereby making the short flaps 2a' and 3a' wavy.
  • An object of the present invention is to provide a slider which permits easy open/close of a zipper bag and can be fitted to a bag which is a finished product easily.
  • Another object of the present invention is to provide a zipper bag which can be judged apparently to have been opened and therefore is suited to be used as an envelope for a confidential letter.
  • Another object of the present invention is to provide a zipper bag which has a slider and has good sealing performance.
  • Another object of the present invention is to provide a slider which can be fitted to a pseudo top-zipper bag stably and does not stick out from an end of the bag even without a stopper when the slider has opened the zipper.
  • Another object of the present invention is to provide a slider which does not deform short flaps of a pseudo top-zipper bag.
  • a zipper bag which has a zipper composed of a concave portion and a convex portion which are provided on inner surfaces of a pair of flaps located in an opening portion of the bag and are capable of engaging with each other is provided with a slider which comprises a center leg, a pair of side legs which are located on both sides of the center leg and are connected to the center leg at their upper portions and holes which are made among the center leg and the side legs and the flaps are to come through.
  • This slider is fitted to the opening portion of the bag in such a way that the center leg is inserted between the concave portion and the convex portion of the zipper and that the side legs extend over the flaps and press the concave portion and the convex portion, and the slider opens and closes the zipper by sliding along the zipper.
  • the center leg of the slider may have a cutter portion on a side facing a zipper opening direction. If the flaps of the bag are fused together or if a seal is provided on the opening of the bag, when the slider is moved for the first time, the cutter portion cuts the fused portion of the flaps or the seal. Thus, it can be apparently judged whether or not such a bag has been opened, and such a bag is suited to be used as an envelope for a confidential letter.
  • the bag as a closing type.
  • the slider is fitted to bases of the zipper, and the front film and the back film of the bag are extended upward and fused together above the slider.
  • the bases of the zipper are fused to the front film and the back film only at their lower portions.
  • the center leg of the slider has a projection at its lower part.
  • This projection is in contact with the lower surface of the engaged concave and convex portions of the zipper of a pseudo top-zipper bag.
  • the projection comes into contact with the end of the bag, whereby further movement of the slider can be prevented.
  • the trouble that a half of the slider sticks out from the end of the bag can be avoided. Consequently, the work to fit a stopper or to form a stopper portion by use of a welder is no longer necessary.
  • the center leg of the slider has a bulged portion.
  • This bulged portion or the projection is in contact with the lower surface of the zipper, and thereby, the slider is prevented from coming off.
  • This slider can be fitted to a bag which is a finished product by inserting the center leg between the concave portion and the convex portion of the zipper, and thus, this type of sliders are suited to be fitted to bags which are mass-produced by fusion-cutting.
  • projections which protrude from the ceiling of the slider and face the upper surface of the zipper are formed on the connecting portion between the center leg and the side legs. These projections serve as spacers, and the trouble that the ceiling of the slider rubs against short flaps and makes the short flaps wavy is prevented. Also, with this arrangement, the friction between the slider and the flaps becomes small, and the smoothness of movement of the slider is improved.
  • Fig. 1 shows a zipper bag 1 to which a slider according to the present invention is fitted.
  • the bag 1 is a conventional one made by fusion-cutting or by fusing and cutting.
  • the slider 10A is made integrally by injection of resin.
  • Fig. 2 shows the first embodiment 10A of such a slider, and this slider has a center leg 11 and a pair of side legs 21.
  • the center leg 11 and the side legs 21 are connected to one another at their upper sides, and holes 29 in which flaps 2a and 3a of the bag 1 can go through are formed.
  • the center leg 11 has grooves 12 on both sides in the middle portion, and a concave portion 4a and a convex portion 4b of a zipper 4 are capable of coming into the grooves 12 respectively. Further, above and below the grooves 12, the center leg 11 has bulged portions 13 and 14. Moreover, as shown in Fig. 2e, a cut-out 15 is made on a side facing the zipper opening direction.
  • the side legs 21 sandwich the center leg 11 from both sides, and bulged portions 22 are made on the side legs 21 opposite the cut-out 15 of the center leg 11.
  • the slider 10A of the above-described structure is fitted to the bag 1 by using its own flexibility in the following way: while the zipper 4 is opened, the center leg 11 is inserted between the flaps 2a and 3a; and the bulged portion 14 is made overcome the concave and the convex portions 4a and 4b (see Figs. 3a and 3b). As shown in Fig. 3a, the part of the concave portion 4a and the part of the convex portion 4b which have come into the cut-out 15 at that time are pressed by the bulged portions 22 and engage with each other. Also, as shown in Fig.
  • the part of the concave portion 4a and the part of the convex portion 4b which have come into the grooves 12 are separated by the center leg 11 and stay in the spaces among the center leg 11 and the side legs 21.
  • the flaps 2a and 3a are in the holes 29.
  • the slider 10A which have been fitted to the bag 1 in this way does not come off upward because the concave and convex portions 4a and 4b are in the grooves 12 and the cut-out 15 and are sandwiched by the side legs 21 from both sides. It is possible to detach the slider 10A from the bag 1 by pulling the side legs 21 outward. However, as long as such deformation is not made, merely pulling the slider 10A upward does not cause the slider 10A to come off.
  • the slider 10A adopts the following construction.
  • a slightly recessed triangle mark 23 is given (see Fig. 2a). This mark 23 indicates that a slide of the slider 10A in the direction shown by the vertex of the triangle results in closing the zipper 4. Such a mark may be provided on the slider 10A by printing or the like.
  • the center leg 11 and the side legs 21 are tapered, and all the corners are rounded off. These arrangements are for easy fitting to the bag 1 and for smooth sliding.
  • the bulged portion 14 is tapered downward.
  • At least one of the bulged portions 13 and 14 which are located above and below the grooves 12 may be formed on the inner surfaces of the side legs 21, not on the center leg 11.
  • Fig. 4 shows the second embodiment 10B in which bulged portions 13' are provided on the inner surfaces of the side legs 21 instead of the bulged portion 13 of the center leg 11.
  • Fig. 5 shows the third embodiment 10C.
  • the structure is basically the same as those of the first and second embodiments.
  • the same members and parts are provided with the same reference symbols as used in the first and second embodiments.
  • This slider 10C has neither the bulged portions 13, 14, 22 nor the grooves 12 of the first embodiment.
  • the center leg 11 of the slider 10C has a separating portion 12a which separates the concave portion 4a and the convex portion 4b of the zipper 4 from each other and a cut-out 15 extending from the separating portion 12a to the zipper opening side of the slider 10C.
  • Each of the side legs 21 of the slider 10C has a pressing portion 24 opposite the cut-out 15 and a relieving portion (cut-out) 25 opposite the separating portion 12a.
  • the concave portion 4a and the convex portion 4b which have come into the cut-out 15 are pressed by the pressing portions 24 and engage with each other. Also, the concave portion 4a and the convex portion 4b are separated from each other by the separating portion 12a of the center leg 11.
  • the relieving portions 25 are to push the separated concave and convex portions 4a and 4b backward smoothly.
  • the relieving portions 25 are not necessarily cut-outs but may be recesses.
  • sliders 10A, 10B and 10C are designed in the premise that they are fitted to bags which are finished products.
  • the sliders 10A and 10B of the first and second embodiments can be automatically fitted to bags under production and can be introduced into market as bags with a slider.
  • Fig. 6 is a schematic view of a process of automatically fitting sliders 10A to bags under production.
  • Sliders 10A are stored one upon another in a vertical hopper 30, and when a rod 31 is moved forward in a direction of arrow "C", the slider 10A on the bottom is pushed out of the hopper 30.
  • Bags are produced by a conventional method (for example, by fusing).
  • a wide film 1' was folded in two, and a zipper 4 is fused. Then, the two-folded film 1' is transported to the hopper 30 (fitting station X 1 ).
  • the zipper 4 is opened by a separator 32, and a slider 10A is fitted.
  • a bag 1 is cut off from the film 1' at a fusion-cutting station X 2 .
  • the rod 31 is moved to fit sliders 10A to zippers 4.
  • the slider 10A is capable of sliding easily so as to open and close the zipper 4. However, if the slider 10A slides from the closing position too easily, the bag 1 will be opened unnecessarily. In order to avoid such trouble, as shown in Fig. 7, the front and back films of the bag 1 are fused together at a place 5 in the opening portion 7 right under the zipper 4.
  • Fig. 7a three sides (shadowed portions) of the bag 1 are fused, and further, the portion 5 is fused.
  • the slider 10A completely closes the zipper 4
  • the lower part of the center leg 11 of the slider 10A is in contact with the fused portion 5 and is pressed by the fused portion 5.
  • This pressure works as resistance to a slide of the slider 10A in the direction to open the bag 1, and thus, the slider 10A is temporarily fixed in the closing position.
  • This fixing force is not so strong, and when the sldier 10A is picked by fingers and is slid in the direction to open the bag 1, the center leg 11 separates from the fused portion 5.
  • the front and back films of the bag 1 may be fused together in a spot 6.
  • Fig. 9a corresponds to Fig. 2d
  • Fig. 9b corresponds to Fig. 2e
  • Fig. 9c is a view obtained by cutting the slider along the line c- c in Fig. 9b.
  • the slider 10A' shown in Fig. 9 is slightly different from the slider 10A shown in Fig. 2 in shape. However, the slider 10A' is basically the same as the slider 10A except having a cutter portion 16.
  • This slider 10A' is used in embodiments shown by Figs. 10 and 11.
  • the bag 1 shown by Fig. 10 has a seal 8 between the flaps 2a and 3a.
  • the cutter portion 16 cuts the center portion of the seal 8 (the portion indicated with arrow "C" in Fig. 10b). Because the cutter portion 16 of the slider 10A' is sandwiched between the side legs 21, the cutter portion 16 never harms the user and is safe.
  • the bag 1 shown by Fig. 10 is apparently judged whether or not it has been opened, it is suited to be used as an envelope of a confidential letter. Further, the lower side 1a of the bag 1 is opened so that a letter or the like can be put into the bag 1, and after putting things into the bag 1, the lower side 1a is closed, for example, by fusing.
  • the seal 8 may be a cellophane adhesive tape.
  • Fig. 11 shows an embodiment of a closing type bag 1 with a seal 9.
  • two sheets of sealing material are laid on the outer surfaces of the flaps 2a and 3a, respectively, and the two sheets are fused together on the whole peripheral sides as shown by the shadowed portions.
  • the two sealing sheets are fused together at the sides 9b and 9c and fused with the front and back films of the bag 1 at the sides 9a, 9d and 9e.
  • a cut is formed at a portion indicated with arrow "D", and when the bag 1 is opened, first, the side 9b is taken off by use of the cut. Thereby, the slider 10A' appears. Next, when the slider 10A' is slid in a direction to open the Zipper 4, the cutter 16 cuts the side 9c of the seal 9.
  • the bag 1 shown by Fig. 11 has a closing function as well as a sealing function.
  • Figs. 10 and 11 can be modified in various ways.
  • the flaps 2a and 3a may be fused together so that the cutter portion 16 will cut the fused portion when opening the bag 1.
  • the seal 9 may be provided to cover only the slider 10A'.
  • such a bag may be provided with a fused portion 5 or 6 for temporarily fixing the slider 10A' in the closing position.
  • a closing type zipper bag 100 is described. As shown in Fig. 12, the bases 4c of the zipper 4 is fused to the front film 2 and the back film 3 of the bag 1 only at their lower parts Y 1 , and the slider 10A is fitted to the bases 4c of the zipper 4. The front film 2 and the back film 3 of the bag 1 extend upward covering the slider 10A and form an opening side 7.
  • the zipper 4 is closed by use of the slider 10A, and the upper parts Y 2 of the front film 2 and the back film 3 are fused together from one end to the other end.
  • the front and back films of the bag cover the slider 10A and are fused together at their upper portions Y 2 .
  • the bag 1 can be sealed firmly, and the bag 1 is suited to be stored with food.
  • the user cuts off the upper portion Y 2 with scissors.
  • the bags 2 and 3 can be cut in a direction right above the fused portion Y 1 , the bag can be opened by hand easily.
  • the bag 1 can be used as a zipper bag with a slider in the above-described way.
  • the lower side (not shown in Fig. 12) of the bag 1 is not fused and stays open. After things are put into the bag 1 through the open lower side, the lower side is sealed.
  • Fig. 13 shows another embodiment of a slider according to the present invention.
  • This slider 310 is made integrally by injection of resin.
  • the slider 310 is composed of a center leg 311 and a pair of side legs 321, and these legs 311 and 321 are connected to one another at their upper parts.
  • the slider 310 is used for a zipper bag which is of a pseudo top-zipper type 1 shown by Fig. 18d.
  • This zipper bag has a zipper 4 composed of a concave portion 4a and convex portion 4b at the upper opening, on the inner surfaces of the front film 2 and the back film 3.
  • the center leg 311 has a separation wall 312 which separates the concave portion 4a and the convex portion 4b of the zipper 4 from each other, a cut-out 313 wherein the concave portion 4a and the convex portion 4b come into engagement with each other and a bulged portion 314 which is made under the separation wall 312 (see to Fig. 15).
  • Each of the side legs 321 has a recessed portion 322 opposite the separation wall 312 and a pressing portion 323 opposite the cut-out 313.
  • the center leg 311 has a projection 315 which protrudes from the bulged portion 314 and extends under the cut-out 313.
  • the slider 310 of the above-described structure is fitted to the bag 1 by use of its own flexibility in the following way: while the bag 1 is opened, the center leg 311 is inserted between the concave portion 4a and the convex portion 4b of the zipper 4; and the side legs 312 are placed outside the front film 2 and the back film 3 (see Fig. 17). At this time, as shown in Fig. 17a, part of the concave portion 4a and part of the convex portion 4b are separated from each other by the separation wall 312. Also, as shown in Fig.
  • part of the concave portion 4a and part of the convex portion 4b which have come into the cut-out 313 at this time are pressed inward by the pressing portions 323 and come into engagement with each other.
  • the bulged portion 314 and the projection 315 are located under the zipper 4.
  • the slider 310 When the zipper 4 is opened in this way, the slider 310 is positioned at a corner of the bag 1; however, because the projection 315 of the center leg 311 is in contact with the end of the bag 1, trouble as shown by Fig. 19b that the slider 900 sticks out from the end of the bag 1 will never occur.
  • the slider 310 has projections 316 and 317 on the ceiling connecting the center leg 311 and the side legs 312 to one another.
  • the projections 316 and 317 face the upper surface of the zipper 4 (see Fig. 17) and serve as spacers which prevent the upper portions 2a' and 3a' of the front and back films 2 and 3 of the bag 1 from coming into contact with the ceiling of the slider 310. With this arrangement, it is avoided that the upper portions 2a' and 3a' will become wavy.
  • the slider 310 can be fitted to a bag 1 as a finished product easily by inserting the center leg 311 between the concave portion 4a and the convex portion 4b of the zipper 4. This means that sliders 310 can be fitted to bags mass-produced by fusion-cutting, and there is wide usage of the slider 310. Once the slider 310 is fitted to a bag, the slider 310 will never come off because the bulged portion 314 and the projection 315 are in contact with the lower surface of the zipper 4.
  • Zipper bags and sliders according to the present invention are not limited to the above-described embodiments.
  • the open angle of the side legs, the shapes of the grooves and the bulged portions may be changed in any way as long as the objects of the present invention can be attained.
  • the bags may be of a large type such as handbags.
  • the sliders are not necessarily of an integral construction. It is possible to assemble a slider from some parts (a center leg and side legs) when the slider is fitted to a bag.
