Detailed description of the invention
As depicted in figs. 1 and 2, the short neck anti-fake bottle lid of compound type of the present invention comprises inner cap 1, enclosing cover 2, combination cover 3, outer sleeve 4 and check valve 5.It is outside that enclosing cover 2 is fixedly connected on inner cap 1, and it is inner that check valve 5 is arranged on combination cover 3 by flush fit mode.Combination cover 3 comprises the inner sleeve 32 of toppling over outlet device 31 and bottom on top, topples over outlet device 31 and is contained in inner cap 1, and cooperatively interacted by threaded portion and inner cap 1.The anchor fitting for fixing with container bottle neck 6 is provided with in inner sleeve 32, anchor fitting comprises axial securing means for impeller and circumferential anchor fitting, shown in composition graphs 3, circumference anchor fitting is the some spline fins 33 be longitudinally arranged on inner sleeve 32 inwall, axial securing means for impeller is for being arranged on inner sleeve 32 inwall and acclivitous pawl 34, spline fin 33 is positioned at above pawl 34, a lower end part for spline fin 33 is positioned at below pawl 34 upper surface, and spline fin 33 and pawl 34 in height partially overlap.
Outer sleeve 4 is fixedly connected in combination cover 3, lower external face, in the middle part of combination cover 3, outer wall is provided with circumferential groove 35 and some longitudinal fins 36, outer sleeve 4 inwall is provided with hoop boss 41 and some longitudinal projections 42, hoop boss 41 is positioned at circumferential groove 35, and longitudinal fin 36 is staggered with longitudinal projection 42.Outer sleeve 4 upper end inwall is provided with the circular protrusion 43 inwardly stretched out, inner cap 1 lower end is provided with hoop antelabium 11, the internal diameter of circular protrusion 43 is slightly less than the external diameter of hoop antelabium 11, before container shows and opens, hoop antelabium 11 is positioned at below circular protrusion 43, container is opened in process, hoop antelabium 11 moves to above it below circular protrusion 43, when container is sealed again, hoop antelabium 11 is interferenceed with circular protrusion 43, hoop antelabium 11 can not be moved to below circular protrusion 43 again, thus this container of customer can be pointed out to be opened, the container filling deception customer again preventing from illegal person from utilizing having opened.
As depicted in figs. 1 and 2, the short neck anti-counterfeit container of compound type of the present invention short neck anti-fake bottle lid has been installed, container finish is suitable for holding check valve 5, and check valve 5 and bottleneck inwall flush fit, for sealing with container, bottleneck 6 outer wall of container is processed with some spline projections 61, the below of spline projection 61 is processed with annular boss 62, spline fin 33 on inner sleeve 32 inwall is staggered with spline projection 61, make circumference between inner sleeve 32 and container bottle neck 6 fixing, pawl 34 on inner sleeve 32 inwall is resisted against on the lower surface of annular boss 62, make axial restraint between inner sleeve 32 and container bottle neck 6.
Except above-mentioned embodiment, present invention also offers another compound type short neck anti-fake bottle lid and short neck anti-counterfeit container, the difference of itself and above-mentioned embodiment is that circumferential anchor fitting and axial securing means for impeller are positioned at sustained height and are integrated, namely on the inwall of inner sleeve, only pawl is processed with, the bottleneck of container is processed with the groove corresponding with pawl, when assembling, the groove alignment of pawl and container neck is press-fited, after pawl enters groove, be subject to the restriction of groove, thus realize circumferential fixing and axial restraint, it is shorter and smaller that the combination cover of this kind of embodiment can do.
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.
