Description
Technical field
The present invention relates to a kind of screw thread safety interlocking mechanism of container, protection child's mechanism, the opening of this container is equipped with an external screw-thread line.
The present invention be more particularly directed to a kind of screw thread safety interlocking mechanism that is used for such as the container of bottle, this mechanism comprises that a screw thread is screwed in the coaxial external plug that inside stopper on the described container and integral body cover this inside stopper, this external plug has when applying axle pressure and rotation on the stopper externally, drives the ability of this inside stopper by brake system.
Background technology
For the screw thread locking mechanism of the container of the opening that is equipped with threaded line, protection child's safety device is just occurring many years ago.
These devices comprise two stopper/lids that are enclosed within another, and each stopper forms the upper end wall of a lateral cylindrical wall and this cylindrical wall of sealing.
The inside that this inside stopper is included in its cylindrical wall lip-deep one allows this stopper to seal the thread of this container and some permissions drive this inside stopper by the rotation of this external plug device on its cylinder exterior wall and/or the end by screw thread.External plug whole cover this inside stopper on coaxial with this inside stopper, this external plug comprises multiple arrangement on portion's wall within it, these devices are used for, by on this external plug, apply axially/rotational pressure is along the closing direction of this container or open direction, rotation drives this inside stopper, this pressure allows the actuating device of this external plug to cooperate with device for mechanical corresponding to inner stopper, can transmit rotatablely moving of described inner stopper then.
In these two stoppers any one all comprises some springings, and these springings allow the actuating device machinery of outside and inner stopper to throw off, and these springings are realized with the stopper identical materials with injection molding.
The protection child's that some are such safety interlocking mechanism is described in a plurality of patents, and some such patent exemplarily is disclosed hereinafter.
The first kind of device that proposes in European patent EP 0631943 relates to (the protection child's) a kind of safety interlocking mechanism that comprises the container of thread, this safety interlocking mechanism comprises two nested stoppers, inner stopper is used to seal described container, external plug is used to drive this inside stopper, so that open or close this container by the aggregate motion of compression and/or rotation.
In this device:
The inside stopper that-this screw thread is screwed into comprises, on the outer surface of its cylindrical wall, one groove that constitutes by continuous laminar rib, this groove is a radial groove shape and extends on the outer surface of the wall of the upper end of inner stopper, the thin slice of this radial groove has along the limit of the length of the hand of rotation opened orientation and is preferably placed at minor face in the plane of longitudinal central axis of the closing member that comprises this container;
-this external plug comprises, externally the inside of the wall of the upper end of stopper is lip-deep, some projections, this surface, inside is deliberately made and is protruded shape (closing this cylindrical wall), when applying axle pressure on by the wall in the upper end of described external plug and causing the elastic deformation of described wall, these projections are engaged in the groove of this inside stopper.
From this moment, by on the surface, inside of the wall of the protrusion end of this exterior stopper, implementing axle pressure, on described stopper, apply rotation then, by the projection of this external plug, the rotation idol is delivered on the radial groove of this inside stopper, so that turn on this inside stopper from this container.
As mentioned above, this mechanism also is included in the laminar groove that is orientated on the cylinder exterior wall of this inside stopper, the effect of this groove is feasible, when the projection of external plug is not engaged in the inclination thin slice of radial groove of this inside stopper, the inside stopper that the rotation screw thread is screwed in this external plug easily.
This mechanism also comprises and passes through external plug, irrespectively rotate second drive system that drives this inside stopper with this first drive system along hand of spiral, so that this external plug is in shutoff operation, drive this inside stopper by simple rotation, and there is no need applying axle pressure on the exterior wall of the protrusion end of this external plug: this drive system is by the device formation of for example representing with projection on the device of for example using " anterior face " expression on a plurality of inner cylindrical wall that are positioned at this external plug and the outer cylinder wall that some are positioned at this inside stopper.
This mechanism that is called safety interlocking mechanism that is used for child has a plurality of shortcomings that show in use.
For example this external plug (as inner stopper) is made by a kind of polymeric material that how much has elastic performance, the projection on the surface, inside of the wall of the upper end of this external plug is made with identical materials and the topside injection-molded on the described inner surface by described stopper obtains: as the upper wall of the upper end of this external plug for protrude and repeatedly impelled axial compression-rotation so that open this container by implementing couple, the elastic memory of this structural materials dies down and the distortion of the wall of this upper end may become similar constantly by the fatigue effect of material, makes projection can engage and make this inside stopper can be screwed into the rotation of direction or rotational direction along any one screw thread relatively consistently and drives.
Therefore, when producing the fatigue effect of material, the wall of the upper end of this external plug is no longer separated fully with the outer surface of the wall of the end of this inside stopper: because can with the braking of necessary axial compression-these two stoppers of irrelevant to rotation ground generation, so this mechanism no longer is perfectly safe.
Related to one as another device of the target of European patent EP 0602925 and comprised the locking mechanism that the child of the container of a thread does not open, this locking mechanism also comprises two stoppers that are enclosed within on another, this inside stopper is used to close described container, and this external plug is used for by axial compression and/or rotatablely moves driving this inside stopper to open or closing containers.
In this mechanism:
-this external plug comprises that the inside of the wall of end is lip-deep thereon, and microscler braking bar that some are radial oriented and the springing in the part in the central are so that keep the wall of the upper end of the wall of upper end of this external plug and this inside stopper to separate;
The inside stopper that-screw thread is screwed into comprises, and is lip-deep in the inside of its cylindrical wall, a thread and some radial oriented microscler braking bars on the wall of end thereon.These have inclination (along the hand of spiral of this inside stopper) surface and are subjected to rotation along hand of spiral so that drive the inside plug period of the day from 11 p.m. to 1 a.m when described external plug, rest on the braking bar of this external plug.But, when described stopper is subjected to rotation along rotational direction, during the axial force on the wall of the upper end of this external plug that before do not applied, the bar on the surface, inside of the wall of the upper end of this external plug just slides on this bevelled surface and inner stopper is not driven.
Therefore cause, axle pressure on the wall of this upper end by being applied to this inside stopper continuously obtains turning on of this inside stopper, therefore described wall is near the wall of upper end that should the inside stopper, and cause the braking of bar of wall of the upper stopper upper end of this inside stopper, therefore this inside stopper is driven by the external plug rotation.
Be applied to the pressure on the wall of upper end of this external plug from relieving, owing to cause two open circuited elastic systems of stopper, so the disengagement of the braking bar of the braking bar of this external plug and this inside stopper.
Yet, comprise the mechanism that is called safety interlocking mechanism that is used for child of two stoppers, also have the shortcoming that occurs when using.
For example for external plug, device that is made of the braking bar of external plug and the springing that occurs on the surface, inside of the wall of the upper end of described stopper all are to have some natural elastomeric polymeric material (passing through injection-molded) by a kind of mono-to implement.Or rather, this springing is made of 4 tongues, and these 4 tongues vertically are connected to by an end in their end on the surface, inside of wall of upper end of described stopper.These 4 tongues constitute and the coaxial virtual cylindrical wall of this external plug.When exerting pressure on the wall in the upper end of this external plug, these 4 tongues tend to be separated from each other in their bottom, and are then on the wall of the upper end of this inside stopper, crushed during the applying of whole above-mentioned pressure.
When unclamping described pressure, this tongue must return a upright position.But, in fact, being used on this external plug unscrewed the repetition of the axial stress (axle pressure-rotation) of this mechanism, the fatigue of drive configuration polymeric material, this fatigue is by the similar constant distortion of this springing and all or part of fracture of this springing is shown.
Therefore, when static the surface of the upper end of two stoppers separate fully no longer each other and their position close mutually, tend to cause the accidental braking of the driving gear of the driving gear of external plug and inner stopper.Therefore this mechanism that is called safety interlocking mechanism that is used for child no longer is perfectly safe.
As another device of the target of European patent EP 0725012, the locking mechanism that a kind of child who comprises the container of a thread does not open is proposed, this locking mechanism comprises:
Be used for driven inside stopper that cylinder lateral sidewall and end wall are housed;
The cylinder of band opening drives shell, makes the upper shed of this cylindrical shell have slightly the diameter greater than the diameter of the support of inner stopper, and this makes this inside stopper occur on described cylindrical shell.
In case be inserted in this cylindrical shell, this inside stopper in the bottom by described cylindrical shell against a circle keep described cylindrical shell, this inside stopper the top by described cylindrical shell on outer fringe surface against an outer annular thing keep described cylindrical shell.
Cylinder driving shell is included in a plurality of brake equipments on its inside face, and these brake equipments can also be the guide piecees of this stopper.
For inner stopper, make this inside stopper can be on the outside lateral sidewall of described stopper by the mono-brake equipment of the inside stopper that cylindrical shell drove.When on shell, applying the pressure that shell is descended and be braked and be used to drive the rotating machinery idol of shell of this inside stopper, from this moment, by the brake equipment of cylindrical shell and a plurality of brake equipments of described inner stopper, carry out the Mechanical Driven of cylindrical shell to inner stopper.
Open circuited springing is that the blade by the bottom circle of this inside stopper constitutes, these blades have identical constituent and connect described bottom circle by an end in this blade tip, and these blades are contained in the described circle when exerting pressure on cylindrical shell from the top down.
Therefore show, because these devices that use in this device must apply vertical power on cylindrical shell, at first need to grip the whole outer rim of described shell according to a more uncomfortable motion, on the outer rim of this shell, apply the vertical power that is used to produce to the braking of described shell and stopper then, rotation by this cylindrical shell at last drives this inside stopper, so these devices cause being difficult to drive inner stopper.
Also show, open circuited springing is positioned on the bottom circle of this inside stopper and with the structural materials that is same as this stopper and cylindrical shell (constituent) to be implemented, when this material of frequent use, this material may lose a part of elastic performance, and may reach fatigue state, for example this material can produce the crack and lose its elasticity, even fracture.
At last, as another unit describe of the target of patent GB2209156 a kind of safety interlocking mechanism of the fire extinguishing hole that is used to supply water.This device comprises the external plug that the inside stopper made with polyamide technology and aluminum alloy are made.
Inner stopper is provided with a thread on the wall within it, and this thread cooperates with the thread of water outlet ozzle.
By constituting the outer boundary ring of guide piece, this external plug remain on a coaxial position of this inside stopper in, this outer boundary ring coaxially keeps two stoppers, constitutes the disconnection springing of these two stoppers.
One spring only leans against in the suitable coaxial endless groove between their opposed upper faces.
Constituting of device driven compressed-rotated to external plug to inner stopper:
Be positioned at lip-deep 3 teeth in inside of the upper end of external plug, these 3 teeth when producing compression-rotation, are engaged in 3 cavitys, and these 3 cavitys are on the outer surface of the upper end of this inside stopper.
Yet fact proved that such device is difficult to implement, because:
Need one relatively the operation of machinery accurately and side by side make these 3 teeth enter into 3 cavitys bigger slightly than the diameter of tooth, therefore need good hand skill and need a large amount of effort, so that can implement the driving of opening or closing;
A kind of disconnection springing of the metal spring of determining by diameter can have very long service life, but because this being applied in especially needs big manpower and special manually skill when handling, so seldom handle this springing;
This safety interlocking mechanism proof is not suitable for the locking mechanism such as the container of bottle fully.

-first function is, when externally apply on the stopper (1), when decontroling axle pressure then, this external plug of coaxial guiding (1) moves with respect to inner stopper (40);
-the second function be, when externally not applying whole axle pressure on the stopper, assists actuating device to drive this inside stopper along the single direction rotation that the screw thread of this mechanism is screwed into.As shown in Figure 6, the cross section of this thin slice (6) is roughly elongated rectangular shape, the producing along the inclination angle of planar obit simulation (7) along to the direction location (along arrow) of central tendency and at the root and tangent plane (8) formation one angle " α " of this thin slice (6) of this thin slice (6).
Inner stopper (40) also comprises the upper end wall (42) of a cylinder lateral sidewall (41) and closed this cylinder lateral sidewall.On the outer surface of upper end wall (42), has the brake equipment (Fig. 3) that forms by annular element (43), the diameter of this brake equipment is less than the diameter of this inside stopper, but equals to be positioned at the diameter of the lip-deep annular element in inside (4) of wall of the upper end of external plug (1).This annular element (43) includes the tooth with annular element (4) similar number.
Also be provided with some guide piecees on the outer surface of cylinder lateral sidewall (41), these guide piecees comprise some thin slices (45), and these thin slices (in the embodiment shown) are carried out two functions simultaneously:
-first function is that guiding external plug (1) moves with respect to the coaxial of inner stopper (40);
-the second function be, when externally not applying whole axle pressure on the stopper, assists actuating device to drive this inside stopper along the single direction rotation that the screw thread of this mechanism is screwed into.As shown in Figure 6, the cross section of this thin slice (45) is roughly elongated triangular shaped, and the inclination angle along planar obit simulation (46) of this thin slice (45) produces along the direction location (along arrow) of tendency entad and at the root and tangent plane (47) formation one angle " β " of this thin slice (45).
This annular element (4,43) tooth (5,44) be shaped as parallelepiped rectangle type (Fig. 9), it comprises that some are when passing through inclined-plane (clinoplane) (92,93) glancing impact is at the lateral sidewall (90 of its mechanical abutting end extension, 91), inclined-plane (92,93) are separated from each other by a horizontal plane (94).
This shape of tooth is such, when not having axle pressure on the stopper externally, but on described external plug, apply when rotatablely moving, the clinoplane (92 of the tooth (5) of annular element (4), 93) and the tooth (44) of annular element (43) can slide over each other (their chances near and when causing contacting with each other), and the tooth of described annular element can not be braked the rotation that also can not cause by external plug and drives this inside stopper.
With good grounds shape memory springing of the present invention (20) (Fig. 2) between the wall of the upper end of inner stopper and external plug.Described springing (20) is hollow cylinder-truncated cone type, comprises a circular ring-shaped part (21), one cylinder-truncated cone sidewall (22) and include a cross bar (2 3) and the wall of the upper end that has hole of some openings (24).
The diameter of the springing of this shape memory is inserted into this springing in annular element (4) and (43) being convenient to less than the internal diameter of braking annular element (4) and (43).
Combination by thermoplastic elastomer is annotated the shape memory springing of realizing by mould and is placed on two walls (3) of upper end of stopper and the position of function place between (42).
The thickness of shape memory springing (20) is slightly greater than the distance between the wall of end (3) and (42), so that except whole axial compression, this external plug (1) can be rotatablely moved (along opening direction), and does not drive this inside stopper (40).
During axial compression on this external plug (1), the springing of shape memory (20) is compressed, and is deformed in the border that is contained in annular element (4) and (43) fully.Shape memory springing deformation in compression is discharged the air that is present in the zone that can brake two annular elements (4) and (43).
External plug can be rotated and be driven this inside stopper, particularly turns on direction along screw thread.When the axial compression end, the shape memory springing recovers its initial shape, particularly by reclaiming the air of initial volume.These two stoppers are by being thrown off braking away from each other: external plug no longer can drive this inside stopper, the particularly direction of turning on along screw thread.
Finish according to mechanism of the present invention, need a lid (60), be used to close this container (48) (constituting inner stopper (40)), in this container, be marked with material, for example can absorb osed top container (not shown) in-to-in moisture by described mechanism with property.
In above-mentioned example according to mechanism of the present invention, closing by thin slice (6) and (45) of this mechanism undertaken according to the present invention, when external plug (1) is subjected to when screw thread is screwed into single the rotatablely moving of direction, this thin slice (6) and (45) are only leaned on mutually: the thin slice (6) of the external plug that drives along the direction of arrow (49) begins to contact the thin slice (45) of inner stopper (40) and drive described inner stopper along closing direction by its steep surface.
In opposite mode, external plug (4) is turned on direction along screw thread and is subjected to along single the rotatablely moving of arrow (50), and thin slice (6) is gone up at the clinoplane (46) of this thin slice (45) by its clinoplane (7) and slided: inner stopper is not subjected to turn on the driving of moving along screw thread.
Open mechanism of the present invention in order to turn on by screw thread, external plug (1) must be subjected to axle pressure, turns on the direction rotation along screw thread then.Like this, external plug (1) is by the close inner stopper of extrusion shapes memory springing (20).
The tooth of the annular element (4) of external plug (1) is braked in the tooth of the annular element (43) of inner stopper (40): inner stopper is just driven by external plug (1) rotation, and closing organ is turned on easily and separated with the container (not shown) easily.
