Cassette of the present invention breaks lobe lid, and the inwall of wherein said lower sleeve is provided with some longitudinal fins and acclivitous projection and forms the anchor fitting be fixed to by lower sleeve on container.
A kind ofly above-mentioned cassette is used to break the container of lobe lid, the oral area of described container is suitable for holding described valve seat, there is outside container finish an annular protrusion and some longitudinally projections, described acclivitous projection to be positioned at below annular protrusion and to interference with it, and described longitudinal fin to be distributed between longitudinal projection and mutually to interfere.
The break upper limb of lower edge and lower sleeve that lobe lid difference from prior art is to break cassette of the present invention lobe lid arranges upper cover of cassette of the present invention is not connected by breakable bond but independent two adjacent parts, lug is also no longer be connected directly between in lower sleeve or cover rim, but many convex tendons are set on lug inwall, be connected on the edge of lower sleeve or upper cover by convex tendon, lug main body place and lower sleeve or cover rim is made to there is no direct connection relational, the wall of lug main surface and lower sleeve or upper cover is positioned on the same face, convex tendon is then positioned at the pars intramuralis of lower sleeve or upper cover, like this, when rotating the convex tendon that upper cover is sheared on lug, convex tendon just cannot outwards extrude the shearing force avoiding groove walls, and inevitable groove lug come off expose on upper cover or lower sleeve of being cut off, warning container is unlocked, such structure, the material making toughness stronger also can be cut off disengaging by stable, ensure that the stable of antifalse effect.
Cassette of the present invention breaks in lobe lid, arrange groove to be further communicated with the second groove by the first groove and to form, first groove is positioned at the outer wall of upper cover or lower sleeve, second groove is positioned at the inwall of upper cover or lower sleeve, and make the first groove be greater than the second groove along upper cover or the circumferential width extended of lower sleeve inwall along the width that upper cover or lower sleeve outer wall circumference extend, lug is made to be arranged in the first groove, convex tendon is arranged in the second groove, which further increases the shearing force of groove to convex tendon, and because the second groove is less than the first groove along upper cover or the circumferential width extended of lower sleeve inwall along the width that upper cover or lower sleeve outer wall circumference extend, after lug comes off, second groove can play the effect of covering to inner structure, more attractive in appearance in appearance.
Below in conjunction with accompanying drawing, the cassette of the present invention lobe lid that breaks is described further.
Detailed description of the invention
As shown in Figure 1, the cassette of the present invention lobe lid that breaks comprises upper cover 1 and lower sleeve 2, and the lower edge of upper cover 1 is adjacent with the upper limb of lower sleeve 2 and separate mutually.As shown in Figure 4, the inwall of lower sleeve 2 is provided with some longitudinal fins 10 and acclivitous protruding 11, there is outside container finish an annular protrusion 12 and some longitudinally projections 13, being inclined upwardly of lower sleeve 2 protruding 11 to be positioned at below annular protrusion 12 and to interference with it, longitudinal fin 10 is distributed in longitudinally interferes between protruding 13 mutually, is fixed on container by lower sleeve 2.
As shown in Figure 2, the upper limb of lower sleeve 2 is provided with two lugs 3, the inwall of lug 3 is provided with two convex tendons 31, lug 3 is connected on the upper limb of lower sleeve 2 by convex tendon 31, as shown in Figure 3, the sidewall lower edge of upper cover 1 is provided with two grooves 4, groove 4 comprises the first groove 41 and the second groove 42, first groove 41 is positioned at the outer wall of upper cover 1, second groove 42 is positioned at the inwall of upper cover 1, first groove 41, second groove 42 is connected, first groove 41 is greater than the width of the second groove 42 along the extension of upper cover 1 inwall circumference along the width that upper cover 1 outer wall circumference extends, as shown in Figure 4, lug 3 is arranged in the first groove 41, convex tendon 31 is arranged in the second groove 42.
As shown in Figure 1, the cassette of the present invention lobe lid that breaks also comprises and topples over outlet device 5, the top of toppling over outlet device 5 by screw thread fit in upper cover 1, bottom outer wall is provided with the connecting portion 6 extended radially outwardly, the upper surface of connecting portion 6 is provided with the first teeth portion, as shown in Figure 2,4, lower sleeve 2 upper inside wall is provided with radially-inwardly protrusion 7, the lower surface of protrusion 7 is provided with the second teeth portion, connecting portion 6 is placed in the bottom of protrusion 7 and interferences with it, first teeth portion is meshed with the second teeth portion and interferes, and makes to topple over outlet device 5 and keeps fixing with lower sleeve 2.The below of toppling over outlet device 5 is also provided with check valve, and check valve comprises valve seat 8 and is placed in the spherical spool 9 in valve seat 8, the top of valve seat 8 be a tight fit in topple over outlet device 5 inwall on, the bottom of valve seat 8 is a tight fit in container finish.
The break assembling process of lobe lid of cassette of the present invention is such: first by corresponding with the lug of two on lower sleeve 23 for the groove of two on upper cover 14 upper cover 1 is assembled into lower sleeve 2 together with, then will topple over outlet device 5 spinning or to be press fit in upper cover 1 and to make connecting portion 6 abut to below protrusion 7, first teeth portion is intersected with the second teeth portion and is engaged, being press fit into by check valve topples in outlet device 5 again, finally whole bottle cap is press fit on container, being inclined upwardly of lower sleeve 2 is made protruding 11 to be stuck in annular protrusion outside container finish 12 times, longitudinal fin 10 coordinates with the longitudinally projection 13 outside vessel port is staggered.
As simple variant of the present invention, also can be connected on the lower edge of upper cover by lug, groove is arranged on the upper limb of lower sleeve; The quantity of lug and groove can arrange multiple.
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
