Description

A fastening device having a rib and groove track {A combination device by the fastener which has the rib and groove track}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener device having ribs and groove tracks that can be sealed and engaged by alternating tracks, and more particularly to corresponding occlusal surfaces. The fastener device formed by the predetermined adhesive force between the ribs and the groove tracks can be used to seal or bind various bags and containers, thereby providing ribs and groove tracks that are easy to use and slim in structure. It relates to a binding device by a fastener having.

The zipper-opening bag that can accommodate a variety of contents has been disclosed a great amount of technology at home and abroad.

The mechanical mechanism of the rail and channel occlusal parts, which are horizontally aligned with the turrets on the corresponding inner surfaces, is mainly made of low density polyethylene (LDPE), but the texture of the occlusal part This is a very hard and hard structure that can be opened and closed relatively simply.

 Owing to the coercion by forceful pressing and the forced force release method, more grip force than necessary is required, and the operation is difficult for children or the elderly who are inevitably weak grip force. In addition, it is not possible to simply use a flexible material in which the occlusal force is poor and the value as a product is lost.

Although the slider type opening / closing bag is known for the above reason, due to the increase in the unit cost due to the man-hours in the manufacturing process, it is only limited to some applications.

Although the rails and channels are pre-fused at both ends of the turret while they are interlocked with each other, even though they are slightly flattened at the time of interlocking, the rails and channels are formed of a large amount of resin material and have a thickness of about 1.6-1.8 mm. Silver is relatively thick compared to the bag film substrate having a thickness of about 0.05-0.12 mm at most, and fatigue phenomenon is always concentrated at both ends of the occlusal part, so that a rupture phenomenon occurs frequently during use.

Due to the above reasons, the surface-fused products of both occlusal parts have been released. However, even if the unit cost increases due to the labor, it is not a fundamental problem and the rupture phenomenon remains after use for a predetermined period.

Occlusal method by rail and channel element is inevitably exposed to physical deformation during use, and even if it is closely intimately initially, a gap may occur after a certain period of time.

Since the zipper opening bag is a method of physically engaging and releasing each element between grip elements by force, the rigid material cannot be used even more.

Therefore, in case of integral extrusion, the choice of film material is limited, and the materials used at home and abroad are mainly limited to Low Density Polyethylene (LDPE), and it is a soft material, but it is not easy to open and close the film. It also has a fatal flaw as a bag for merchandise packaging with less transparency.

In addition, when fusing the zipper type tape formed with each element with various bag composite film materials due to the limitations of the material, the temperature rise time is required, and the work speed falls and the production efficiency is reduced. There is not much concern about quality deterioration.

Oriented Poly Propylene (OPP), which has a high transparency and a thickness of about 30-50㎛ among the film materials, has a feature that makes the packaged products stand out clearly, and its usage is increasing year by year. Advancing, it adds luxury and convenience.

In other words, heda type bags (Halls with holes on the header can be hooked to the hooks, and adhesives on the other side can be used to open the contents freely), and various accessories and accessories are individually packaged. Pulley bags are widely used in clothing, confectionery and bakery for shirts and sportswear.

The bags do not need any adhesive, and the adhesive on the horizontal line is applied on the outer top of the bag opening or the inner flap of the bag, so that the bag can be easily opened and closed without a large force.

But contrary to many advantages, they are not free of fatal vulnerabilities.

In order to prevent the adhesive from working in advance, the liner, which is removed immediately before use, causes inconvenience in use and increases in manufacturing process price.

In addition, even if a rather strong adhesive is applied at a predetermined position, it may be exposed to foreign matters or be contaminated by the back of the hand when entering or exiting the contents, which may limit the reopening and closing, and a stronger adhesive to increase the number of openings and closings. If you use it, whenever you open and close the flap, it just adds to the discomfort that the adhesive sticks to your hands.

Due to the diversification of daily consumption patterns, the demand for tray-type containers to be kept closed is increasing in various small contents having a predetermined volume. It will be stored randomly in most zippered bags.

 Packaging bags that can accommodate bulky clothing and vegetables, food bags, and bags used for storing or transporting trash are made of HEIDEN with a high tensile strength of about 50-100 µm. High Density Polyethylene) is mainly used.

These turrets contain pairing bands that are paired at their corresponding positions, but they are not easy to bind smoothly when the contents are accommodated at a certain level or a little, and they may stretch and tear with some force. They accept the contents below a certain level and bind them together, or they are excessively accommodated and attached to each other with a separate adhesive tape, ignoring the unique function of the binding band.

What is used in disposable rebonding bands, such as a diaper, mainly uses the adhesive band in which the predetermined | prescribed adhesive was apply | coated on the smooth tape.

However, if the liner is separated and exposed to contamination by foreign substances or hands in earnest on the adhesive surface, repeated rebonding is impossible.

The present invention is to overcome the limitations of the existing products, to solve the above problems, in accordance with the trend that the user-centered consciousness is gradually emphasized in one side of the supplier due to the change of domestic and foreign consumer life patterns and desires, various bags and The opening and closing of the container opening and the binding between the binding materials is designed to smoothly materialize.

According to the present invention, ribs and groove tracks that are alternately interlocked with each other at predetermined positions of a bag or a container or a binding base are formed to correspond to each other by a cohesive force, thereby acting as a fastener, thereby causing the bite and release by a coercive grip force. It is an object of the present invention to provide a binding device by a fastener having ribs and grooves, by restricting the pressure-sensitive adhesive from being exposed to foreign substances, thereby increasing convenience in use and intrinsic corresponding functionality.

In order to achieve the above object, the present invention is to smoothly apply a pressure-sensitive adhesive having a predetermined adhesive strength only to each groove track of the fastener tracks formed to correspond to each other at a predetermined weight, and to closely interact with the rib track. Allow the occlusal body to occlude.

 In the binding band bag according to the fourth embodiment, as shown in Fig. 23, a fastening device by a fastener having a myriad of ribs and groove tracks is formed.

The tube film synthetic resin film lower end portion 82, which is continuous by co-extrusion, is subjected to pre-fusion bonding, and a pair of binding bands 83, 85 and 84, 86 are respectively formed at mutually corresponding positions of the upper opening 87. In the binding band bag (80) forming the (), each of the binding bands on the side of the binding band (83,86) alternately overlapping to the outside and the side of the binding band (84,85) overlapping inward, respectively Type fasteners 93, 96 and 94, 95 are formed.

In forming the binding band type fasteners 93 and 96 on the inner side of the binding bands 83 and 86 overlapping with the outside, a plurality of rib tracks 25a having a predetermined width, height and length in the longitudinal direction are provided. -z), and groove tracks 23a-z having the same width and height, that is, depth and length, corresponding to the rib tracks 35a-z on the other side are formed between the rib tracks 25a-z. Let's do it.

On the bottom of the groove tracks 23a-z, the adhesive 27 is smoothly applied at a predetermined weight having a predetermined adhesive force, so as to be interlocked with the rib tracks 35a-z alternately defined with the other side surfaces. do.

In forming the binding band type fasteners 94 and 95 at predetermined positions on the outer surface of the binding bands 84 and 85 overlapping the inside, a plurality of rib tracks 35a-z and a plurality of grooves are formed. The multi-binding method of the rib tracks 25a-z and the groove tracks 23a-z of the binding band-type fasteners 93 and 96 overlapping to the outside by forming the tracks 33a-z in the same manner as described above. They are formed so that they can be interchanged and bound together.

In the binding band type fastener according to the fourth embodiment as shown in Figs. 26A and 26B, as a somewhat modified example, a fastening device by a fastener having ribs and groove cells is configured.

In the band cell type fastener 100, a plurality of rib cells 105 and groove cells 103 are formed in the surface portion of the base band 107.

The rib cell 105 is formed in plural with a size, height, and spacing of a predetermined shape (circular square rhombus, etc.), and the groove cell 103 is formed in the area of the baseband 107 excluding the rib cell 105. To be

On the bottom of the groove cell 103, the adhesive 27 is smoothly coated with a predetermined weight, having a predetermined adhesive force, so that the counterpart (the one side and the other side of the band cell fasteners have the same structure, and thus, there is no separate classification in the drawings, and only the cross-sectional view) It is formed to be combined with each corresponding rib cell 105 of the band-cell fastener 100 to be multi-binding.

Thus, the present invention, as shown in Figure 2a, when opening and holding the lip portion (17a, 17b) of the upper end of the double-sided opening and closing bag 10 with both hands, one side fastener 20 is formed to correspond to both sides of the inner side Peeling starts with the groove track 23 of the < RTI ID = 0.0 >) < / RTI > and the upper rib track 35a or the lower rib track 35b of the other fastener 30, which is precombined at the time of production, while the groove track of the other fastener 30 is started. Also in (33), the upper rib track 25a or the lower rib track 25b of the one side fastener 20, which is determined in advance as described above, and peeling proceed simultaneously, and the double-sided opening and closing bag 10 can be opened. will be.

The adhesives 27 adhered to the groove grooves 23 and 33 on both side groove tracks may have various adhesive strengths depending on the use of the double-sided opening and closing bag 10, and the peeling force may be changed in proportion thereto. Can be used depending on the strength and weakness.

 As shown in Fig. 2b, after opening, when closing, sliding both fingers in one direction while gently pressing from the left or right end of both fasteners (20; 30), the fastener (20; 30) double-sided opening and closing bag (10) Since it does not protrude bulge outwardly, it can easily proceed smoothly without giving great frictional pain to fingers, etc., and children and the elderly can be completely sealed without excessive force.

It also eliminates the need for a separate slider bag that is inefficient in terms of production, cost, and utilization.

Therefore, the above fastener has a very thin slim structure, but the perfect sealing force of various peeling strengths is ensured according to the adhesive strength of the adhesive, so that a constant force is applied to the occlusal portions of each element of the rail and the channel. It can be compared relatively to a conventional zipper-opening bag that can be opened and closed with physical deformation.

If the conventional turret is divided into a zippered turret and a so-called pulled turret, its features are clearly divided.

In other words, the former has excellent sealing force but requires a lot of force to open and close, the latter is easy to open and close, but the concept of sealing is ambiguous. Moreover, since the adhesive at a certain position is always exposed by foreign matter or hands, re-adhesiveness Because it falls.

However, since the double-sided opening and closing bag 10 of the present invention is a structure that combines only the advantages of the typical existing opening and closing bag, it is possible to use efficiently.

In other words, because of the adhesive opening and closing method, opening and closing can be performed very easily according to the intended use, and it can have a predetermined perfect sealing force, and if the contents to be accommodated are not fine powder or viscous liquid, it is a groove having an adhesive force. Since the tracks 23 and 33 maintain a horizontal plane lower than the corresponding rib tracks 25 and 35, they are prevented from being contaminated by foreign matter or the back of the hand, so that reopening and closing is permanently performed unless the inherent performance of the adhesive force is exhausted. It becomes possible.

In the above embodiment, the double-sided opening and closing bag 10 is a tubular through the hole (Ring Die, Circle Die) having a circular slit molten resin in the extruder by Blow Film Extrusion method (Tubular) Film), and in the case of a double hermetic seal, each of the rib tracks 25a and 25b and the rib tracks 35a and 35b, which serve as a fastener at a predetermined position of the extrusion core, are also formed in a continuous form. The sub track 23 and the groove track 33 are extruded together with the extruded film.

In addition, the adhesive 27 is continuously applied to the groove tracks 23 and 33 of the film cooled by air-cooling (upward) or water-cooling (downward), respectively, and fused and cut to a predetermined size to open and close the bag. To form.

As described above, in producing the double-sided opening and closing bag 10 of the present invention by continuous co-extrusion, it is possible to secure a very large variety of advantages.

First, the limitations of film materials can be overcome.

In the existing zipper opening bag, as mentioned, the occlusal portion by the rail and the channel is a method of opening and closing by forcing a physical force between the elements, and thus has a natural limitation of using a somewhat flexible material.

Therefore, the material used mainly has to be selected as Low Density Polyethylene (LDPE), the disadvantages of the material is bound to accept as it is.

That is, since it is gradually produced in a low temperature and air-cooled method, since the transparency is poor, the merchandise of the package or the contents to be accommodated is poor, so that it can be used only for limited demand.

However, the double-sided opening and closing bag 10 of the present invention because the bite (20; 30) between the tracks of the bite is opened and closed by a pressure-sensitive adhesive without a physical deformation, a somewhat hard but very high transparency of the film Oriented Polypropylene Film ( OPP) material can also be used to overcome the limitations of the material.

As will be described again in the following specific examples, the same material as the film surface to be finally fused can be used even when the track of the fusion fastener 20s; 30s is separately bonded to the substrate 70, instead of the integral type method. Since it is not limited by the bag material, it is possible to smooth the fusion operation regardless of the material by the single layer or the multiple layers by the composite film.

Second, the structural slimmer can increase the functionality of the product.

In order to maintain a proper sealing force, the zipper opening bag has a structural weakness that must be made to bulge the zipper bag opening part, since the bite of the rail and the channel must exist more than a predetermined size.

Therefore, compared with the film thickness of the zipper bag, the difference between 10 times and 20 times smaller than the film thickness, of course, reduce the production efficiency of the zipper bag work, there is also the possibility of wrinkles, give friction pain to the finger when sealing, or when opening It is the cause of rupture of both ends of the part.

However, each track of the double-sided opening and closing bag 10 of the present invention is sufficient enough to be 3 to 4 times the film thickness, which is the width and height of the adhesive (27) is not exposed to foreign matters, material savings and production efficiency It can be increased, giving rubbing pain to the hands when used, and neither end of the occlusal rupture.

As shown in Fig. 3, in the bag-type fusion fasteners 20s; 30s, the soft touch type fasteners 20t; 30t are formed with the entire back portion except for the fusion aid wings 77a, 77b; 87a, 87b. It is.

In addition, since a predetermined space is secured by at least one landing gear 21a, 21b; 31a, 31b, each of the fusion aid wings 77a, 77b and the fusion aid wings 87a, 87b is a double-sided opening and closing bag. It has a predetermined space | interval with the said film surface part of (10), and is fused to the fastener fusion parts 37a, 37b; 57a, 57b sequentially.

In addition, since the double-sided opening and closing bag 10 is formed by the surface fusion of both left and right side portions (14s, 15s) according to the predetermined size, that is, the upper and lower left and right sides of the soft touch fastener (20t; 30t) is completely fused, The recess remains as a space where air flow is blocked.

Therefore, the predetermined closed space acts as the air capsules 22 and 32, and as shown in the virtual description perspective view, when the soft touch fasteners 20t and 30t of the double-sided opening and closing bag 10 are mutually sealed. By the predetermined air capsules 22 and 32, the air layer has an appropriate cushion, so that it can be sealed very smoothly with very little force.

As shown in Fig. 5, in the bag-fused fasteners 20s; 30s, the reverse open limiting fasteners 20r; 30r are respectively provided at the reverse action reference point SR of the corresponding track rear part of the left or right predetermined side. Fusion auxiliary wings 77b and 87b having a predetermined width are formed from the points spaced by the negative width of the integral multiples d1 to dx, and the bag fusion fasteners 20s and 30s are alternated with each other. To form an occlusal form.

Thus, as shown in Figs. 6B, 6C, and 6D, when the reverse open limiting fasteners 20r; 30r are alternately interlocked, the forward action reference points SI coincide on any vertical line, but the reverse direction is reversed. The operating reference points SR are inconsistent with each other on an arbitrary vertical line, so that a predetermined force arbitrarily opened in the reverse direction is not the same as when the double-opening and closing bag 10 is to be opened in the forward direction.

Therefore, when opening the double-sided opening and closing bag 10 in the forward direction, the groove track (23a) and rib track (35a) is sequentially from the operating reference point (SI) because the forward operating reference point (SI) and force point (F) is the same It peels easily, and it opens more easily.

 However, when the double-sided opening and closing bag 10 is opened in the reverse direction, the reverse action reference point (SR) and the force point (F) are spaced apart by d1, d2, d3 minus width, respectively, groove track (23b) and rib track (35b) does not start peeling from the working reference point (SR), but must be peeled out from any intermediate point in sequence, so that the greater the width, the more the force is dispersed, and the contents opened and infiltrated arbitrarily There will be no more spills,

In addition, since the reverse opening limiting fasteners 20r and 30r are alternately interlocked, even mutual force points are inconsistent on an arbitrary vertical line, so that all forces required for the double-sided opening and closing bag 10 to be arbitrarily opened can be distributed in a double triplet. Since there is no choice but to be opened, the user may not easily open it by an unwanted random force.

On the other hand, as shown in Figure 6a, even if the basic fasteners (20g; 30g) are alternating with each other, the forward action reference point (SI) and the reverse action reference point (SR) by mutually matching on any vertical line, the double-opening and closing bag 10 ) And a predetermined force arbitrarily opened in the reverse direction is equal to each other.

That is, in the forward direction and in the reverse direction, the groove tracks 23a and the rib tracks 35a are opened when the double-sided opening and closing bag 10 is opened in the forward direction because the force points are the same as the respective forward reverse action reference points (SI, SR). When the double-sided opening and closing bag 10 is opened in the reverse direction, the groove tracks 23b and the rib tracks 35b are sequentially peeled off so that there is no difference in force between them.

When the reverse opening limiting fasteners 20r; 30r are fused, similarly to the soft touch fasteners 20t; 30t, the corresponding film surface portion of the double-sided opening and closing bag 10 and the predetermined closed air layer are secured. As a result, the air capsules 22 and 32 are naturally formed.

In the above embodiment, the bag-fused fasteners 20s; 30s are extruded by the extrusion method, and the melted resin in the extruder is continuously taped through a die with a slit. To extrude in sets,

In the case of the basic fasteners (20g; 30g), the tracks and the fusion aid wings (77a, 77b) 87a, 87b are integrally addressed and continuously extruded.

 In the case of the soft touch fasteners 20t; 30t, the tracks and the fusion aid wings 77a, 77b; 87a, 87b are also integrally extruded by the landing gears 21a, 21b; 31a, 31b. do.

In the case of the reverse opening limiter type fasteners 20r and 30r, the fusion aid wings 77a and 77b and the fusion aid wings 87a and 87b are integrally spoken in succession according to the corresponding tracks and their respective shapes. Extruded.

The bag fusion fasteners 20s, 30s are continuously extruded in the form of a tape, preferably cooled by water cooling (downward), and a pressure-sensitive adhesive 27 is formed on the bottom of each groove track (23; 33). Apply uniformly and continuously.

In addition, by applying the pressure-sensitive adhesive 27, the bag-fused fasteners 20s; 30s, which have undergone a cooling and drying process within a predetermined time, are alternately interlocked with each other, and the bag-shaped fasteners 20s; 30s of the tape type are completed. Winding is sequentially on the reel by the winder (Winder).

Accordingly, the double-sided opening and closing bag 10 is formed by the bagging machine, and the bag-type bag-type fusion fastener 20s; 30s wound around the reel is fusion-processed in the corresponding area, so that the bag can be easily and smoothly re-closed and closed again and again. It can form a (Pack).

The bag-integrated fasteners 20 and 30 and the bag-fused fasteners 20s and 30s in the double-opening and closing bag 10 are wider and have a very thin thickness than those of the zipper opening and closing bag.

Therefore, since the range of the occlusal contact between the rib tracks 25a and 25b and the groove tracks 33 is large, there is no fear of misalignment between the fasteners. Even if sealed from any center, it is possible to seal completely.

As shown in FIG. 8, when the opened flap opening and closing bag 40 is to be sealed, the flap 47 side fastener 20 is gripped with one hand to form a horizontal line on the top side of the front film 42. By alternating with the fastener 30 in place.

Between the fastener 20 of the flap 47 and the fastener 30 on the top of the front film 42, as shown in Fig. 9, the trajectory is traced by a roughly defined range of rotation radius in which the flap 47 is folded. It corresponds.

The groove track 23 of the flap 47 side fastener 20 is partially contacted with a predetermined position of an upper rib track 35a or a lower rib track 35b of the front film 42 upper fastener 30. When the adhesive layer is adhered to each other, the groove track 33 of the upper fastener 30 on the front film 42 also has the upper rib track 25a or the lower side of the fastener 20 on the flap 47 side which is already combined between the tracks by the user. The rib track 25b and partial adhesion proceed simultaneously.

 At this time, while sliding gently along the horizontal line of the outer surface of the flap 47 while gently pressing in one direction of the left or right, or in both directions from the start of the mutual coupling of the predetermined contact point, by the occlusion between both fasteners (20; 30), The adhesive is to be able to seal the flap opening and closing bag 10.

Since each of the rib tracks 25a and 25b and 35a and 35b has a very thin structure, it is very easy to select and engage an arbitrary contact point between the tracks. The surface of the rib tracks 25a, 25b and 35a, 35b slide together and engage with the groove tracks 23; 33.

In the above embodiment, the flap opening and closing bag 40 may be produced as a tubular film or a flat film by a blow film extrusion method.

In addition, in the bag material, it is not limited to the feeder, the stream or the single layer multilayer composite film.

The reason why the original flap bag material is mainly Oriented Polypropylene is because the outstanding transparency makes the packaged products stand out more luxuriously.

As described above, the flap opening and closing bag 40 can also be integrally formed with the front and rear films 42 and 43 with the fasteners 20 and 30 tracks. The Hedda turret and the bald can eliminate the biggest weakness of the turret.

That is, in order to prevent malfunction before use, a liner for protecting the adhesive, which is necessary, is unnecessary. During the use, the groove tracks 23 and 33, which are adhesives of each fastener, are applied to the rib tracks 25a, 25b) and (35a, 35b) can be naturally protected, so there is no risk of exposure to foreign objects or hands, so that it can be permanently reopened without stickiness.

As shown in FIG. 10, when the closed type tray container 60 is to be sealed, when the lower tray 65 or the upper tray 64 is gripped and closed while being slightly pressed, a predetermined rotation is performed by the hinge 63. While folding and drawing a trajectory defined by a radius, the fasteners 20 and 30 respectively formed on the inner side of the sealed tray container 60 are alternately interlocked and sealed.

The groove tracks 23a and 23b of the lower tray 65 fastener 20 and the rib tracks 35a and 35b of the upper tray 64 fastener 30 are bonded, while the upper tray 64 fastener 30 is bonded. The grooves 33 and the rib tracks 25 of the lower tray 65 fastener 20 are alternately engaged with each other and bonded to each other, thereby sealing.

Transparent or opaque tray-type containers have been rapidly expanding in demand due to the variety of their uses, but they have been limited in their use because of the inability to control the contents.

However, by applying the pressure-sensitive adhesive having a variety of strength to the sealed tray container 60, it is possible to overcome the limited area of the application.

  In the above embodiment, in forming each track of the fasteners 20 and 30 of the hermetic tray container 60, as shown in Fig. 11, when the film is formed on a film sheet having a predetermined thickness, a smooth film is shown. The sheet may be formed by a press forming method.

12A, 12B, 12, and 12D in various embodiments of the bag and container described above, each single or multiple tracks may be It can be selected as a sealed method, double sealed method, triple sealed method, or quadruple sealed method.

In addition, the strength of the pressure-sensitive adhesive 27 can also be used to be adjusted according to the intended use.

As shown in Fig. 16, the applied pressure-sensitive adhesive of the groove track 23, which is maintained by the rib tracks 25a and 25b of the fastener 20 formed on each of the corresponding substrates, is kept at a lower level by a predetermined depth. (27) The surface shows that contamination is prevented by foreign matter or the back of the hand.

Therefore, if it is not directly exposed to the fine powder or viscous liquid, it will perform the function of the fastener by permanently exhibiting the adhesive force.

As shown in Figs. 17A, 17B, and 17C, the track cross sections of the fasteners 20 and 30 are transformed from a right angle basic type to a ladder type and a round type, respectively.

The deformation of the cross section is alternating, depending on the material on which the track is formed, so that the occlusion is more effective, so that the function of the fastener is exerted, and various modifications are possible.

In the above embodiment, as shown in Fig. 17A, the width, height or depth of each track can be determined as a predetermined value.

According to various experiments, the width (w) of each track is preferably about 1.5 mm, the height (h) or the depth (d) within about 0.25 mm, and the value may vary depending on the application. Can be.

In the ladder track as shown in FIG. 17B, the ratio of the large width (L / w) and the small width (S / w) is set to about 9: 1 so that the interlocking inclination angles become effective values. The value can be changed as much as the application is used.

 In the round track having a predetermined radius R at the track edge as shown in Fig. 17C, the area mainly applied is the fasteners 20, 30 of the flap-opening bag or the fastening band-type fastener. As in (93,95) and (94,96), it can be advantageously applied to a fastener device that is in a state of complete separation between fasteners and must hold the initial contact with each other. It goes smoother.

As shown in Fig. 18, depending on the conditions of the pressure-sensitive adhesive 27 to be applied, i.e., applied at a predetermined weight or more, and whether the viscosity is thinned due to some cause, or a temperature condition in use, etc., the over may be generated. It is a double safety device structure that can prevent the floor phenomenon through the main part.

As shown in Figs. 19A and 19B, regardless of the shape of the side furrows 24a and 24b or the vertical furrows 26a and 26b, it is possible to sufficiently prevent the overflow phenomenon.

As shown in Fig. 20, depending on the characteristics of the adhesive 27 to be applied or the characteristics of the groove track 23 base material of the fastener, the adhesive 27 is more closely adhered to the bottom portion thereof, that is, In order to enhance weather resistance, which is a force for maintaining a stronger fixing force, it can be realized by forming predetermined irregularities in the bottom portion thereof.

As shown in Fig. 21, when the fasteners are extruded in a continuous tape manner, the stripe-shaped concave-convex 71a can be formed simultaneously with the groove track 23.

As shown in Figs. 22A, 22B, 22C, and 22D, the uneven shapes of various shapes are not formed by simultaneously forming and integrally integrating with the bottom portion of the groove track 23 while extruding the fasteners in a continuous tape manner. The bottom portion of the groove track 23 of the extruded fastener can be formed through a secondary process such as a pressure hole.

Of the various irregularities, the intaglio form is preferably better than the embossed form, and the adhesive layer 27 having a predetermined thickness is smoothly applied thereon, and the rib tracks 35 of the corresponding fasteners alternately interlocked with each other. Make sure to maintain a smooth adhesive force.

 As shown in FIG. 23, when the predetermined contents are to be bound to the binding band bag 80, the binding bands 83 and 85 and the other binding bands 84 and 86 are respectively formed. Bonding is achieved by alternately overlapping and bonding each other by a predetermined length between the binding band fasteners 93 and 95 and another binding band fasteners 94 and 96.

First, as shown in FIG. 24, one pair, that is, the binding band type fastener 95, holds the binding band 85 fused to the outer surface in one hand and is turned inward, and again, the other side hands bind the band. When the fastener 93 overlaps the binding band 83, which is fused to the inner side, outward by a predetermined section, the binding can be performed by alternately adhering.

 In addition, the other pair is also bound in the same way it is possible to store or transport the binding band bag 80 containing the contents.

Thus, as shown in Fig. 25, the countless groove tracks 23a-z and rib tracks 25a-z of the binding band fasteners 93 and 96 on one side and the binding band fasteners on the other side ( The number of groove tracks 33a-z and rib tracks 35a-z of 94 and 95 are alternately interlocked and interlocked together, thereby being bonded by unevenly bonding.

At this time, the height or depth step between the tracks acts as the interlocking jaws and the interlocking bands, thereby reacting strongly against the lateral forces mainly received between the binding bands (83,85) and the binding bands (84,86). By doing this, they become bound together in a mutually significant way.

Therefore, by forcing a knot, the difficulty of stretching or tearing the band and eliminating the hassle of sealing with a separate tape.

In the above embodiment, the coupling between the binding bands 83, 84, 85, 86 and the binding band fasteners 93, 94, 95, 96 may be integrated by various heat fusion methods, or may be a pressure-sensitive adhesive having strong adhesive force. Can stick.

 As shown in Figs. 27A and 27B, in order to bind the band cell type fasteners 100 to each other, in order to have a counter reaction force against the lateral force acting in the width direction as well as in the longitudinal direction, The principle can be achieved by giving a somewhat modified embodiment.

That is, a structure that serves as ribs and grooves in a predetermined baseband 107 may be designed in an intermittent form of a plurality of repetitive cells having a predetermined size, height, and spacing.

For example, as shown in FIGS. 26A and 26B, they may have a circular shape, an angular shape, or various shapes.

When there is one side, it is an intermittent structure that is spaced apart from each other, but when mutual binding is made, it is continuous in two directions on the X-axis and Y-axis on the plane, and the step between the rib cell 105 and the groove cell 103 is mutually different. It acts as a jam chin and hanger.

 Therefore, the strong adhesive force acting by alternating interlocking action of the corresponding individual cells has a strong reaction force of the lateral force in the four directions, thereby dispersing the force received in various directions by the band cell fastener 100 over the entire surface. Therefore, it can be effectively applied to the required binding.

The practical application of the above may be introduced in places such as adhesive bands (not shown) such as baby diapers having a lot of movement and reattachment frequently.

Although specific embodiments of the present invention have been illustrated and described above, various changes may be made without departing from the spirit and scope of the present invention for those skilled in the art.

Therefore, the following claims are intended to encompass all modifications falling within the scope of the present invention.

As described above, the present invention alternates between the rib tracks and the groove tracks which are formed to correspond to each other, and closely engages with each other by an adhesive having a predetermined adhesive force, thereby opening and closing various bags and container openings, and also binding substrates. It is possible to bond smoothly between them. Therefore, it is possible to have a perfect sealing force with only a small force without coercive grip force, which can be easy to use (Easy), and because it has a strong adhesive force and is not exposed to foreign substances or hands, it is possible to permanently reclosable reclosing. In addition, the limitation of the material can be overcome, so that the product market can be introduced more broadly, and the structure can be slimmed, which is a relatively big change in production and function, and also in the renewal of fundamental equipment.
