The short neck anti-fake bottle lid of compound type of the present invention difference from prior art is that the short neck anti-fake bottle lid of compound type of the present invention is positioned at the lower end of circumferential anchor fitting setting the top of axial restraint device lower end; Can be fixed under the situation of container finish and neck at the combination cover; Make combination overlap short and small, to adapt to the bottleneck of short neck container as far as possible.Because before assembling bottle cap on the bottleneck, bottle cap can be used as an integral body and carries out aggregate erection in advance, and then bottle cap integral body is fitted on the bottleneck, fitting process is simple, and is easy to operate, and efficient is high.
Below in conjunction with accompanying drawing short neck anti-fake bottle lid of compound type of the present invention and short neck anti-counterfeit container are described further.
The specific embodiment
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.Enclosing cover 2 is fixedly connected on inner cap 1 outside, and check valve 5 is installed in combination cover 3 inside through the 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 the inner cap 1, and cooperatively interact through threaded portion and inner cap 1.Be provided with in the inner sleeve 32 and be used for the anchor fitting that fixes with container bottle neck 6; Anchor fitting comprises axial restraint device and circumferential anchor fitting; In conjunction with shown in Figure 3; Circumferentially anchor fitting is for vertically being arranged on the some spline fins 33 on inner sleeve 32 inwalls, and the axial restraint device is for being arranged on inner sleeve 32 inwalls and acclivitous pawl 34, and spline fin 33 is positioned at pawl 34 tops; The lower end part of spline fin 33 is positioned at below, pawl 34 upper surfaces, and spline fin 33 in height partially overlaps with pawl 34.
Outer sleeve 4 be fixedly connected on combination cover 3 in, lower external face; Combination cover 3 middle part outer walls are provided with circumferential groove 35 and some vertical fins 36; Outer sleeve 4 inwalls are provided with hoop boss 41 and some vertical projections 42; Hoop boss 41 is positioned at circumferential groove 35, and vertically fin 36 is staggered with vertical projection 42.Outer sleeve 4 upper end inwalls are provided with the circular protrusion 43 that inwardly stretches out, and inner cap 1 lower end is provided with hoop antelabium 11, and the internal diameter of circular protrusion 43 is slightly less than the external diameter of hoop antelabium 11; Container show open before, hoop antelabium 11 is positioned at circular protrusion 43 belows, container is opened in the process; Hoop antelabium 11 moves to its top from circular protrusion 43 belows; When container was sealed once more, hoop antelabium 11 and circular protrusion 43 interferences made hoop antelabium 11 can not move to circular protrusion 43 belows once more; Thereby can point out this container of customer to be opened, prevent that illegal person from utilizing opened container can deception customer once more.
As depicted in figs. 1 and 2, the short neck anti-counterfeit container that compound type of the present invention is lacked the 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; Be used for sealing with container, be processed with some spline projections 61 on bottleneck 6 outer walls of container, the below of spline projection 61 is processed with annular boss 62; Spline fin 33 on inner sleeve 32 inwalls is staggered with spline projection 61; Make between inner sleeve 32 and the container bottle neck 6 and circumferentially fix, the pawl 34 on inner sleeve 32 inwalls is resisted against on the lower surface of annular boss 62, makes axial restraint between inner sleeve 32 and the container bottle neck 6.
Except that above-mentioned embodiment, the present invention also provides short neck anti-fake bottle lid of other a kind of compound type and short neck anti-counterfeit container, and the difference of itself and above-mentioned embodiment is that circumferential anchor fitting and axial restraint device are positioned at sustained height and are integrated; Promptly on the inwall of inner sleeve, only be processed with pawl; On the bottleneck of container, be processed with and the corresponding groove of pawl,, the groove alignment of pawl and container neck press-fited in when assembling; After pawl gets into groove; Receive the restriction of groove, thereby realize circumferentially fixing and axial restraint, it is shorter and smaller that the combination cover of this kind embodiment can be done.
Above-described embodiment describes preferred implementation of the present invention; Be not that scope of the present invention is limited; Design under the prerequisite of spirit not breaking away from the present invention; Various distortion and improvement that those of ordinary skills make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
