Describe in detail
With reference to Fig. 1, the closure member 10 of Reclosable rectangular 12 and 14 is formed continuously longitudinally by two, and when fitting face-to-face, rectangular 12 and 14 employing shackle principles are fixed together.Rectangular 12 inboard is provided with two can be by ring 16 districts of hook joint, and these two districts are separated by negative hermetically-sealed construction part 20.Rectangular 14 inboard is provided with two zones that are molded with hook part 18, is provided with like this with rectangular 12 ring 16 to be interlocked, and closure member 10 is remained on as shown in the figure closure state; Rectangular 12 inboard also is provided with the positive hermetically-sealed construction part 22 in a center, is used for the negative hermetically-sealed construction part 20 of interlock when closed closure member, thereby constitutes a sealing member.In many application, can be the closure member of closure member 10 as pocket, for example in unsettled US Patent serial number US09/187389 (this paper is with reference to quoting), just described these closure members, just described in this patent application than adopting the fastening better closure member of shackle.As with reference to the instruction of quoting, can make the both sides of closure member integrally formed, as a continuous product, fold again afterwards, make ring and closure member the hook interlock second half on of closure member on half.Alternatively, can make this two semi-closure components separately.Shown in the closure member that limits to very much of width represent the shape of hermetic unit.In many application, the rectangular width of closure member is 0.5 inch or wideer, and its whole interlock thickness is less than about 0.04 inch.
Figure 1A more clearly represents the structure of molded hook part 18, the stringer setting of these parts along rectangular 14, and be suspended in the direction scope of being expert in rectangular 14 the substrate.The hook 18 of adjacent lines is towards opposite longitudinal direction.Each hook part 18 constitutes a hook spare, is used to hook the ring 16 of single fiber or rectangular 12.Can adopt various positive secure components 18 to change the shape of hook, for example mushroom, palm tree, barb or other are from the outstanding structure that can be lived by bail of rectangular 14 substrate.Also have, the present invention enlarge aspect, unnecessaryly form secure component or towards rectangular 14 longitudinal direction or integrally formed with the stringer form.For the occasion of many packaging applications, preferably 0.002 to 0.008 inch of the rectangular basic thickness of each fastener.
The shackle closure member is that than the advantage of convex-concave closure member shown in Fig. 2 and 2A, the shackle closure member can avoid occurring longitudinal shear, in the convex-concave closure member, and the undesired opening that this shearing can occur.By the groove interlock of the fin of first pocket wall 114 and second pocket wall 112 is got up, can seal pocket 108.Because the shearing force F1 and the F2 that apply along pocket wall 114 and 112 respectively make fin 122 slide with respect to groove 120, separate near the pocket edge up to its section, so just make fin 122 and groove 120 open (Fig. 2 A).But the shackle closure member can avoid this N/R situation to take place.As described herein, hook-loop fastener combines and is used to seal section structure, its special advantage is, the shackle interlock can avoid being applied to the shearing force of sealing on rectangular (being that the slide relative that occurring on the direction of sealing surfaces each other being parallel to has been avoided in the shackle interlock).
With reference to Fig. 3 to Fig. 5,, its interlock can be got up by two of closure member rectangular inboards are sticked together Face to face.In the time of separately (Fig. 3), rectangular 14 hook 18 separates with rectangular 12 ring 16.In this view, the hook shape of hook 18 is also not obvious, and this is because these hooks are Unitarily molded on the material of rectangular 14 substrates 23, towards longitudinal direction.Under situation about not compressing, negative hermetically-sealed construction part 20 is Y line space chamber 24, is used to admit positive hermetically-sealed construction part 22.Vertically cavity or groove 24 are limited to by between integrally formed two projectioies of plastic resin of rectangular 12 substrate 28 and the relative guide rail 26.As following will illustrate, for the ease of pull out the guide rail 26 that is molded into from their forming pockets, its thickness has tapering from the substrate to the top.Guide rail 26 can be described as toward each other, thereby forms the Y connected in star, and its minimum interval d1 is less than the interval d2 of its bases.The middle part of arcuate convex 30 between guide rail 26 of substrate 28 extends into a fin, forms a breach at the middle part of Y shape cavity 24.The vertical fin 32 of V-arrangement of positive hermetically-sealed construction part 22 is provided with two ears 34 that separated by recess 36.When rectangular 12 and 14 slided toward each other, the ear 34 of fin 32 was along with fin 32 enters groove 24 and toe-in (Fig. 4).Two rectangular hooks 18 contact herein with ring 16.These two rectangular moving towards each other further again can make the whole interlock in hook He Huan district, and ear 34 outwards protrudes, and enters the sagging position of groove 24.
Under some applicable cases, can select concaveconvex shape like this, promptly at interlocking pattern, certain force of strain is held in hook and environmental protection, thereby can compress between the ear 34 of projection 30 and fin 32, strengthens and the maintenance leak tightness.Make ring 16 have multiple thickness and make the rectangular substrate of closure member very soft, can greatly strengthen the tension force that produces and keep passing the shackle interface.Alternatively, can form the structure of interlock like this, but i.e. certain structure resilience during interlock for example by changing the angle of engagement surface with respect to substrate selectively, so that carry out follow-up compression between sealing surfaces, is opened up to closure member.Can utilize shackle interface or other hermetic unit to keep this compression.
But under some applicable cases, the hermetic unit that must not pass closure member keeps compression just can realize required sealed vol.For example, in Fig. 6, be provided with fin 32 ' and groove 24 ', can be bonded together with the shackle zone loosely of interlock.In this case, can seal by the bending channel 38 that between the auxiliary section of hermetic unit, forms.These rectangular parts of formed closure member are consistent, having reason prediction can stop fluid to pass hermetic unit to flow, be used for the control leakage or make gas flow, but can stop fluid to flow, adopting present method of moulding can make the thickness t p of repetition passage is 0.002 inch or littler.The total length of passage 38 also can influence resistance to flow, is appreciated that in order to increase resistance to flow, and many parallel fins and groove can be set, and also is appreciated that the shape that can improve fin and groove, so that meet the requirement of any given applicable cases.
For example, Fig. 7 represents a kind of improvement, the projection that replaces the groove center among the figure by two littler projectioies 40, can shorten the length that leakage path 38 passes the closure member hermetic unit effectively, and form vertical cavity 42 of an opening along the hermetic unit of closure member interlock, be used to collect and preserve the material of leakage, be used for the air of discharging and the chamber of fluid as one owing to the interlock of hermetic unit, or the like.Because cavity 42 is provided with and is used for two spaces that fastener is rectangular, can be crooked toward each other, it is more soft that structure therefore shown in Figure 6 can also be provided with ground.
Another kind of hermetically-sealed construction as shown in Figure 8.In a side of this closure member the guide rail 70 at a pair of interval is arranged, its opposed inside is by a guide rail interval S
RSeparate the upperlimit of the expection particle of selected interval in the expection particulate material that leaves in the pocket.Will illustrate below adopting with first kind of corresponding continuous molding method of described embodiment, the template of utilizing suitable shape is vertically guide rail 70 and substrate 72 and hook part 18 Unitarily molded being in the same place continuously.Guide rail 70 needs not to be rectangle as shown in the figure, but should be suitable shape, so that the required sealing surfaces relative with the closure member side is provided.At the opposite side of closure member, the globule 74 of resilient material such as osed top honeycomb foam is adhered in the substrate 76 of closure member the width W of this globule 74
BGreater than guide rail interval S
R, the interference between globule and the guide rail can produce remaining pressure between guide rail and little bead surface like this, thereby forms transverse sealing.In this structure, the globule material has enough rebound resiliences, can produce selected disturbance variable between globule and guide rail, and sealing can allow closure member to have the bending of resonable degree and guide rail to move like this, keeps required seal degree simultaneously.A kind of example of resilience globule material is an isocyanurate foam.
After the following method of employing is molded as the closure member substrate, can be injected in globule 74 in the closure member substrate 76, perhaps be bonded in the closure member substrate.Alternatively, as described, can when molded substrate, globule be injected on the resin of substrate with reference to Figure 15.
As a kind of alternative application structure, can carry out abundant leak free occasion simultaneously attempting not need to align, can omit guide rail 70, and the flat surfaces that closure member 74 seals up the substrate 72 between hook 18 rows is set.As described in above-mentioned embodiment, the tension force between the shackle interface can keep the pressure between the closure member.Like this, can the confining force of closure member be worked, and seal by separating the structure in the closure member, shackle is fixed closure member simultaneously, and sealing can stop leakage like this.
Below with reference to Fig. 9, be another kind of hermetically-sealed construction, be provided with a pair of guide rail that separates 90 in a side of closure member, its opposed inside is by a guide rail interval S '
RSeparate, selected interval is more preferably greater than the width W ' of the globule 94 of resilient material
B, this resilient material for example is an osed top honeycomb foam, is bonded in the substrate 96 of closure member opposite side.Will illustrate below adopting with first kind of corresponding continuous molding method of described embodiment, the template of utilizing suitable shape is vertically guide rail 90 and substrate 92 and hook part 18 Unitarily molded being in the same place continuously.From substrate 96, globule 94 thickness H
BSignificantly greater than the ring 16 and the combined thickness of hook 18, thus the substrate 92 that globule 94 is disturbed on closure members one side during ring 16 interlocks of the hook 18 that makes closure member one side and closure member opposite side.When the rectangular force together interlock of closure member shackle, the radially-outer surface 95 of globule 94 helps guide rail 70 and globule 94 to align between guide rail 90.As shown in figure 10, when being provided to the rectangular closing pressure of closure member and forcing the shackle interlock, globule 94 compresses substrate 92 simultaneously.Basad 92 compress globule 94 can make globule stretch to sidepiece, is supported on the inboard of guide rail 90.When the shackle interlock and when having discharged closing pressure (Figure 11), the restoring force of globule 94 makes substrate 92 outside deflections, this deflection makes guide rail 90 inwardly rely on the sidepiece of globule, thus maintain between globule and the guide rail and globule and substrate 92 between sealing load.In addition, the residual compression power in the globule 94 forms required prestrain tension force between shackle, can improve the performance of closure member.
In this structure, the globule material should have enough screen resiliences, this screen resilience provides selected disturbance variable between globule 94 and substrate 92 and the guide rail 90, and sealing can allow closure member to have the bending of resonable degree and guide rail to move like this, keeps required seal degree simultaneously.As shown in figure 11, for when recovering, make the substrate deflection of closure member opposite side, this globule is compared with the rigidity of closure member substrate should have enough shape memory functions, thereby can a little outwards deflection substrate.A kind of example of resilience globule material is an isocyanurate foam.
