Can be repeatedly closed fastener 40 can limit continuous operating path, this path has component of a vector on X and Y direction, and extends to closing end 52 from opening end 50, is used for guided slidable part 100 to move along fastener 40.Another kind of scheme is as shown in Figure 1, can track 46 be set along the side of the fastener that limits continuous operating path 48.

Operating path 48 can be included in the combination of each linear section of moving on the orthogonal direction, and a section is arranged essentially parallel to the directions X operation, and adjacent section is arranged essentially parallel to the operation of Y direction.Each section is by comprising the transitional region combination of arc, and this transitional region has radius of curvature and has periphery with a plurality of points of component of a vector tangent in X and Y direction.Operating path 48 also can be oval-shaped complete curve, or comprises forming to have a series of arcuate segments in waveform patterns such as sine-shaped, sinusoidal path.

Fig. 3 and Fig. 4 are the top views of hold-up vessel 10 shown in Figure 1.Track 46 is corresponding with fastener 40 that can be closed repeatedly along all edges except that being hinged the edge that line 25 occupies of lid 30 and flange 20.Track 46 runs to the opposite side of the hinge lines 25 that comprises closing end 52 from a side of the hinge lines 25 of the opening end 50 that comprises fastener.

In the structure shown in Fig. 3 and 4, track 46 defines operating path 48, this operating path comprises two sections relative arcs 54 and 56, two sections arcs to the container center indent and bending, and by being straight basically but the section 58 relative with hinge lines 25 of slight curvature connects.When track 46 during near near the opening end 50 of the fastener the hinge lines 25, track 46 turns to from fastener, so that guiding sliding part 100 to stop position (a parking place) 60, makes lid 30 rotate or remove from container and do not disturb sliding part 100 around hinge lines 25.

Shown in Fig. 2 a and 2b, track 46 can have the slit 70 on the end face of lid 30, and its recessed element 44 with can be repeatedly closed fastener 40 is corresponding.Slit 70 comprise the most approaching recessed element 44 inside edge 72 and with 72 opposite external side edges 74, inside edge.Slit 70 in the end face 32 of lid 30 forms crimping (bead) 76 in the bottom surface 34 of lid 30, complementary slot in the end face 20 of this crimping and flange 20 80 intersects, and slit is corresponding with the protruding component 42 of the fastener 40 of closure repeatedly.Slit 80 in the end face 22 of flange 20 passes flange 20, forms crimping 82 on the bottom surface 24 of flange 20.Crimping 82 on the bottom surface 24 of flange 20 comprise the most close protruding component 42 opening end 41 inside edge 84 and with opposite external side edge, inside edge 86.

The inside edge 84 of the crimping 82 on the bottom surface 24 of flange 20 limits first edge 90 of the track 46 among the sliding part embodiment described below usually.In a sliding part embodiment, when this sliding part was arranged on open mode, the outer ledge 81 of the slit 80 in flange 20 end faces 22 formed second edge 94 of track 46; And when this sliding part was arranged on closed mode, the outer ledge 74 of the slit 70 in lid 30 end faces 32 formed second edge 92 of track.In another embodiment, when sliding part was arranged to open with two kinds of patterns of closure, the outer ledge 74 of the slit 70 in lid 30 end faces 32 limited second edge 92 of tracks 46.

Shown in Fig. 3 and 4, sliding part 100 is attached to slidably on the track 46 and is removable along operating path 48.Sliding part 100 have the length 102 that is parallel to operating path 48 operation and with its orthogonal direction on the width 104 that moves.As Fig. 5 a, shown in 5b and the 5c, the C shape main body of sliding part 100 comprises the substrate 110 with first surface 112, and first and second

elongate articles

120 and 130 that extend from first surface are arranged.First and second

elongate articles

120 and 130 each the near-

end

122 and 132 that is folded down from the first surface 112 of substrate 110 is all arranged, the far-end 124 and 134 that extends from first surface 112, and interior surface opposing 126 and 136.First elongate articles 120 comprises a pivot 140, from far-end 124 inner surfaces 126 to second elongate articles, 130 projectioies.Second elongate articles 130 comprises and follows rail spare 160, its from the inner surface 136 of far-end 134 to first elongate articles, 120 projectioies.

Following rail spare 160 can align along the length 102 of sliding part 100 with along the width 104 of sliding part 100 with pivot 140.Perhaps, following rail spare 160 can be along the length 102 of sliding part with along the width 104 and pivot 140 skews of sliding part 100.Preferably, shown in Fig. 5 a-5c, follow rail spare 160 and can align with pivot 140 with pivot 140 skews with along the length 102 of sliding part 100 along the width 104 of sliding part 100.

By can be repeatedly closed fastener limits in the configuration of operating path 48, first and second elongate articles 120,130 straddle on the periphery of lid 30 and flange 20, simultaneously pivot 140 and to follow rail spare 160 crossing with the interlocking part 42,44 of fastener.Specifically, pivot 140 can intersect with the opening end 41 of protruding component 42 on the bottom surface 24 of flange 20, can intersect with non-interlocking surperficial 47 of recessed element 44 on the end face 32 of lid 30 and follow rail spare 160.

In the assembly structure shown in Fig. 6 a and 6b, along with pivot 140 and the slit 70 and the crimping on flange 20 bottom surfaces 24 that follow on rail spare 160 and lid 30 end faces intersect, first and second elongate articles 120,130 straddle on the periphery of lid 30 and flange 20.Particularly, under the closed mode shown in Fig. 6 a, the outer ledge that follows the slit 70 on rail spare 160 and lid 30 end faces leans, and the inside edge 84 of the crimping 82 on the bottom surface 24 of while pivot 140 and flange 20 leans.In the open mode shown in Fig. 6 b, the outer ledge 81 that follows the slit 80 on rail spare 160 and flange 20 end faces 22 leans, and the inside edge 84 of the crimping 82 on the bottom surface 24 of while pivot 140 and flange 20 leans.

Pivot 140 can make far-end 124 rotations of sliding part 100 around first elongate articles 120, particularly along the curve section and the transitional region rotation that have at the upwardly extending component of a vector of X and Y side.For this reason, pivot 140 comprises cylindrical outer surface 142 one oval-shaped, that preferably intersect with track 46.For allow sliding part 100 along operating path 48 along curve section or transitional region correctly rotate around pivot 140, pivot 140 is assemblied in the recessed face of curve section or transitional region, follows rail spare 160 simultaneously and assembles along convex side.This just makes that at sliding part 100 substrate 110 of sliding part 100 is with respect to the far-end rotation of elongate articles when the curve section of operating path 48 moves.

Follow rail spare 160 keep usually sliding parts 100 attached on the track 46 and guiding sliding part 100 move along operating path 48.But, follow rail spare 160 and also can be used as a pivot, particularly operating path 48 take be waveform patterns such as sinusoidal waveform the time, need the substrate 110 of elongate articles and far-end to depend on sliding part 100 and relative to each other rotate along the position of operating path 48.The outer surface 162 that follows rail spare 160 is convex preferably, so that friction is minimum when contacting with track 46.But, also needing when the pivot if follow rail spare 160, outer surface 162 is oval-shaped, and is preferably columniform.

Although need rotary slide 100; particularly along in the transitional region of operating path 48; it is necessary keeping the correct location of sliding parts 100 with respect to can be repeatedly closed fastener 40, can correctly locate with respect to fastener to guarantee sliding part 100 and the part (will describe in the back) that interlocking part 42,44 intersects.This just makes more effectively closure or openness fastener of sliding part 100.For example, the correct location of sliding part 100 can comprise that the length 102 of sliding part 100 is arranged essentially parallel to operating path 48, and width 104 is substantially perpendicular to the path.Such location can be arranged on the sliding part 100 and keeps with rotation limited part 180 that fastener 40 that can be closed repeatedly or track 46 intersect by one.

Although the structure that rotation limited part 180 can have multiple different control sliding part 100 to rotate, but the rotation limited part 180 at the sliding part shown in Fig. 5 a-5c comprises the pin 182 that is arranged on the inner surface 126, at the far-end 124 of first elongate articles 120 to second elongate articles, 130 projectioies.As shown in the figure, pin 182 length 102 along sliding part 100 separate from pivot 140, and align with pivot 140 along the width 104 of sliding part 100.As pivot 140, pin 182 by with flange 20 bottom surfaces 24 on the inside edge 84 of crimping 82 lean and intersect with operating path 48.

According to operating path 48, particularly foundation is along the radius of the transitional region curvature of operating path 48, and the distance between limited part and the pivot 140 is limited.Radius of curvature is big more, and the permission distance of separation between pivot 140 and the rotation limited part 180 is big more.Equally, radius of curvature is more little, and the distance that is allowed is more little therebetween.

As pivot 140 with follow rail spare 160, minimum rubs when the shape of the outer surface of pin 182 contacts with track 46.This outer surface can be a convex, serves as some contact to limit crossing.

As previously mentioned, the basic function of sliding part 100 is that when sliding part 100 moved with closed fastener on first direction 36, sliding part was biased to the interlocking part 42,44 of closed fastener 40 repeatedly; When sliding part 100 moves when opening fastener in the second direction 38 opposite with first direction 36, sliding part applies separating force to interlocking part 42,44.Sliding part generally includes the technical characterictic that these functional characteristics are provided.

In the embodiment shown in Fig. 5 a-5c, sliding part 100 comprises the wedge shape part 200 on the far-end 124 that is arranged on second elongate articles 130, but with to follow rail spare 160 adjacent opposite.Wedge shape part 200 is set to away from the first surface 112 of substrate 110 to intersect with the interlocking part 42,44 of closed fastener 40 repeatedly.Wedge shape part 200 comprises inner surface 202 and outer surface 204, opening end 206 and closing end 208.Inner surface 202 and the space between first elongate articles 120 210 at wedge shape part 200 form groove 212, and this groove 212 is assembled along the length 102 of sliding part 100 to the minimum range of the closing end 208 of wedge shape part 200 from the ultimate range of the opening end 206 of wedge shape part 200.

As shown in the figure, wedge shape part 200 can be the truncated cone that concave inner surface 202 and convex surface 204 are arranged.For the frictional force minimum that contacts with the parts of the boundary of fastener 40, the inner surface of wedge shape part and outer surface all can comprise 208 waveform profiles that extend from opening end 206 to closing end.For example, the profile phase of outer surface 204 is protruding for the operating path 48 near opening end 206, and is recessed into respect to the operating path 48 near closing end 208; Simultaneously the profile of inner surface 202 is recessed near opening end 206, and is protruding near closing end 208.

In the sliding part embodiment shown in Fig. 5 a-c, wedge shape part 200 has to be opened and the closed function of closed fastener 40 repeatedly.In the closed configuration shown in Fig. 6 a, the concave inner surface 202 of wedge shape part 200 is partly sealed spherical non-interlocking surperficial 47 of the recessed element that is formed on the lid 30, the inner surface of first elongate articles 120 forms track 46 in the bottom surface 24 of crimping 82 places contact flange 20 from wherein stretching out simultaneously.When sliding part 100 as shown in Figure 3 at first direction 36 when operating path 48 moves, the convergent channel (converging channel) that forms between the inner surface 126 of the concave inner surface 202 of wedge shape part 200 and first elongate articles 120 is biased to interlocking part 42,44 together in the mode of sealing.

In case the length that sliding part 100 has moved operating path 48 at first direction 36 is with closed fastener, sliding part 100 just becomes open configuration by turning to and wedge shape part 200 being placed between the interlocking part 42,44.The flexible labial lamina 43 that the recessed element 44 of the fastener 40 from lid 30 end faces extends can be arranged on the closing end 52 of operating path 48, makes wedge shape part 200 initial separately two elements 40,42.

In the open configuration shown in Fig. 6 b, wedge shape part 200 places between the interlocking part 42,44, thereby the concave inner surface 202 of wedge shape part 200 is partly sealed the interlocking surface 45 of protruding component, and the groove 49 of recessed element is sealed the frustoconical external surface 204 of wedge shape part 200 simultaneously.When sliding part 100 when as shown in Figure 4 second direction 38 moves, the frustoconical external surface 204 of wedge shape part 200 forces the interlocking part to come in 42,44 minutes to open can closed repeatedly fastener 40.
