Detailed description of the invention
A kind of blue bottle cover as shown in Fig. 1 to 5, comprise coaxially arranged inner cap 20, middle cover 30 and enclosing cover 40, inner cap 20 is affixed for same bottle 10, the present invention is preferred, also to be the technical scheme of most convenient be exactly described balsam bottle should consist of the outside thread of the negative thread on inner cap 20 and bottle 10 oral area and be threaded, thus formed Glue packing Bottle.Middle cover 30 and inner cap 20 part socket-connect and arrange flow control mechanism, and middle cover 30 and inner cap 20 part socket-connect and be exactly specifically, inner ring 21 and the middle cover 30 lower end grafting on inner cap 20 top, and both calibers coincide.The effect that flow control mechanism slides mutually by middle cover 30 and inner cap 20 and open or close the fluid passage arranged vertically; Described enclosing cover 40 lower end inner wall arranges negative thread, and interior upper part of the cover outer ring 22 arranges outside thread, and both are threaded at formation; Between enclosing cover 40 and middle cover 30, Elastic buckle is set, in enclosing cover 40 spinning to inner cap 20 or split the clamping of process Elastic buckle make enclosing cover 40 relative fixing with middle cover 30 position.Flow control mechanism in technique scheme and the detailed description of the invention of Elastic buckle have a lot, mainly be divided into: when can radially slide between middle cover 30 and inner cap 20, then Elastic buckle is designed to make enclosing cover 40 and middle cover 30 radially position is relative fixing, like this in the process of enclosing cover 40 spiral screw-in, middle cover 30 is just driven and realizes radially sliding, and can close fluid passage; Otherwise just open fluid passage in the process screwed out.As long as the direction screwed in by enclosing cover 40 spiral when vibrational power flow or screw out opens or closes corresponding with fluid passage.
In other words: the setting of flow control mechanism of the present invention and Elastic buckle mainly contains two kinds of set-up modes: described flow control mechanism is the structure opening or closing fluid passage when middle cover 30 slides axially; Described Elastic buckle is for making enclosing cover 40 and the middle cover 30 relatively-stationary structure in position vertically.Or described flow control mechanism is the structure opening or closing fluid passage when middle cover 30 radially slides; Described Elastic buckle is for making enclosing cover 40 and the middle cover 30 radially relatively-stationary structure in position.
Concrete for the technical scheme slid axially, can be preferred embodiment as shown in Figure 1, 2, described Elastic buckle comprise be arranged on middle cover 30 side face circular groove 31, enclosing cover 40 inwall projection 41, projection 41 and circular groove 31 match; Described flow control mechanism comprises the circular hole that inner cap 20 upper end is arranged, circular hole is outwards dispersed and is arranged some otch 11, middle cover 30 inside is by supporting leg or the affixed core bar 33 of stay bearing plate being with through hole, core bar 33 bottom is plugged in circular hole in consistent manner, and termination core bar 33 is positioned within inner cap 20 sets firmly gear plug 331; Described gear plug (331) is in the ladder shaft-like coaxially arranged with core bar (33), and its upper end is that size becomes large prismoid section downwards gradually, and centre is the circular shaft section that diameter and frustum lower end coincide, and lower end is the termination of largest diameter.
Composition graphs 1, state shown in 2, in such a configuration, enclosing cover 40 is threaded with the outside thread 21 on inner cap 20 by the negative thread of inwall, the projection 41 now forming Elastic buckle snaps together with circular groove 31, when glue will be used, unscrew enclosing cover 40, when just having started rotary outer cover 40, enclosing cover 40 is with middle cover 30 must holding position be relative fixing in the axial direction, along with rotation is carried out, enclosing cover 40 moves to graphic top, core bar 33 affixed in middle cover 30 also must move up, and be frustum owing to keeping off plug 331 top, this moves inevitable very smooth and easy.Certainly, in such a configuration, because core bar 33 is shapes of gyro-rotor, between enclosing cover 40 and middle cover 30, whether the use not affecting glue is mutually rotated.As long as so circular groove 31 is axially arranged along middle cover 30, guaranteed projection 41 and snapped in, as whether being unimportant along the circular groove 31 that side face is through.When the circular shaft section that core bar 33 rises to centre contacts with bore edges, gear plug 331 termination is due to oversize quite different formation position limiting structure to middle cover 30, now, projection 41 and circular groove 31 are just separated from each other under the application force further rotating enclosing cover 40, complete the object opened bottle cap and open fluid passage.And keep off circular shaft section and termination on plug 331 and coordinate with bore edges and make middle cover 30 can not slide.Shown in composition graphs 5, multiple seal strips 12 that the otch 11 on inner cap 20 is formed must be separated from each other, and so glue just can flow out through otch 11, and the gum outlet 32 then arranged through middle cover 30 upper end reserves, and use easily.
After using, screw in the process of enclosing cover, Elastic buckle snaps in, and middle cover 30 is promoted by enclosing cover again and moves down the state of getting back to shown in Fig. 1, achieves closing of fluid passage, avoids glue to be reserved by gum outlet 32 in untapped situation.Make because inner cap 20, middle cover 30 and enclosing cover 40 are all plastics, elasticity is better, the fastening of Elastic buckle of being more convenient for.
Further improvement is: described otch 11 arranges 3 ~ 5.The reasonable quantity of such seal strip 12, can reduce the resistance keeping off the rising of plug 331, core bar 33 and whole middle cover 30, be convenient to again processing simultaneously.
Circular hole on described inner cap 20 and core bar 33 are arranged along inner cap 20 axle core, and supporting leg is symmetrical arranged at least three along core bar 33.Such symmetrical structure is more conducive to each parts uniform force, reduces the possibility of partial failure, improves product life.Supporting leg or be all that concrete structure does not have particular/special requirement in order to ensure that fluid circulates to the stay bearing plate of through hole.
Described projection 41 is evenly arranged at least 2 along enclosing cover 40 inner peripheral surface.Although middle cover 30, enclosing cover 40 are all plastics etc. to be had elastomeric material and makes, projection 41 can not cause damage to the structure of middle cover 30 when extruding middle cover 30, but Elastic buckle fastens, the application force that is separated in order to reduce to wear and tear and reduce, projection 41 still evenly arrange 2 ~ 4 comparatively suitable.
Described projection 41 is spherical or be the prismatic of U-shaped in cross-sectional plane in semicircle.As shown in Figure 3,4.The surface all smooth transition namely contacted with circular groove 31, the wearing and tearing of less fastening or separation and resistance.
As for the structure of radially sliding because radially rotate middle cover 30 just energy communication of fluid passage, the embodiment flowing out glue has a lot, usually be exactly middle cover, in cover through hole be set, rotate to position of eating dishes without rice or wine to plastic emitting during correspondence, just close when orifice position staggers.Will utilize technical conceive of the present invention so accordingly, play effect easy to use, corresponding Elastic buckle only needs middle cover 30, fin that enclosing cover 40 inwall setting position is corresponding, makes middle cover 30 synchronous rotary with it when enclosing cover 40 screws in.
In above-mentioned multiple preferred implementation, the improvement also can further carried out is: the gum outlet 32 of described middle cover 30 upper end is sharpen shapes.Shown in composition graphs 1,2.Gum outlet 32 itself can be closed, is then cut off voluntarily by user and forms; But because general anaerobic adhesive does not need strict separation air, so the present invention preferably pre-sets liquid outlet 32, be convenient to user and directly use.And liquid outlet 32 is processed as sharpen shapes, this is all generally be coated to the anaerobic environment designs such as slit in conjunction with anaerobic adhesive, and sharpen shapes can so that glue be coated within slit.
The present invention is applicable to the packaging of most of glue, is especially applicable to the lower anaerobic adhesive of viscosity, also may be used for the packing of product with similar physico-chemical property, obtain corresponding technique effect.
