Abstract
The utility model discloses a sealed seedling culture bottle plug, which comprises an inner cover; a longitudinal through hole and a soft elastic left-hand cover capable of being turned down on the outer side of the inner cover are arranged in the middle of the sealed seedling culture bottle plug; and an annular groove is formed in the middle of the side wall of the inner cover. The control requirement of the control size of the original external crack is lowered due to the left-hand form, and the external crack is better matched with a bottle opening due to the left-hand form. As the soft elastic left-hand cover applies an inward contraction force to the bottle opening, the probability of ejection of the bottle plug due to increased internal and external pressure difference in the high-pressure sterilizing process is greatly reduced, and the effectiveness of the sterilizing operation is improved; the inner surface in the crack of the original bottle plug is turned into the outer surface by adopting the left-hand form so as to better facilitate washing, disinfection and sterilization; and in addition, the overall shape size of the bottle plug is smaller and the thickness of the left-hand part of the bottle plug is reduced for the contribution to addition of mould holes and increment of production benefits, and materials can be saved by 20% in comparison with the conventional right-hand bottle plug.

For solving the problems of the technologies described above, the utility model adopts the basic conception of technical scheme to be:
A kind of closed type seedling cultivating bottle stopper, comprise inner cap, in the middle of the closed type seedling cultivating bottle stopper, be provided with a longitudinal hole, also have a resilient flexible reverse cover under overturning outside the described inner cap, be provided with an annular groove in described inner cap sidewall middle part.
Further, be provided with the left-hand thread reinforced rib in described resilient flexible reverse cover end.
Further, high in the middle of the closed type seedling cultivating bottle stopper end face, periphery is low.
Further, be provided with a retaining ring that is higher than closed type seedling cultivating bottle stopper top at described longitudinal hole upper end open place.
Further, described inner cap bottom is that the bottom is young, the truncated cone-shaped that top ports is large, and top is cylindrical.
Further, the closed type seedling cultivating bottle stopper adopts macromolecular material.
Further, the closed type seedling cultivating bottle stopper adopts elastomeric material.
After adopting technique scheme, the utility model compared with prior art has following beneficial effect: originally the management and control size of outer crack has reduced the management and control requirement because of employing left-hand thread form, because of left-hand thread make it and bottleneck between better anastomose property is arranged.Because the resilient flexible reverse cover applies inside convergent force to bottleneck, therefore can greatly reduce bottle stopper in high-pressure sterilizing course because the poor rising of external and internal pressure is ejected, thereby improve the validity of disinfecting action; Adopt the left-hand thread form, make that inside face transfers outside face in the crack of former bottle stopper, thereby more be conducive to clean, sterilization and sterilization; In addition, bottle stopper global shape size is less, and the thickness attenuation of bottle stopper left-hand thread position is conducive to increase the mold well number and improves productivity effect, compare with the structure of the positive button-type bottle stopper of tradition, but economical with materials 20%.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the constructional drawing after the upset of resilient flexible reverse cover stoops among Fig. 1;
Fig. 3 is positive left-hand thread bottle stopper shape comparison diagram.
The specific embodiment
As shown in Figure 1, the utility model is a kind of left-hand thread closed type seedling cultivating bottle stopper, comprise inner cap 1, in the middle of left-hand thread closed type seedling cultivating bottle stopper, be provided with a longitudinal hole 2, in this longitudinal hole 2, be plugged with ventilative cotton, also has a resilient flexible reverse cover 3 under overturning in described inner cap 1 outside, be provided with an annular groove 4 in described inner cap 1 sidewall middle part, when resilient flexible reverse cover 3 left-hand threads get off, the high spot of bottleneck enters in this annular groove 4, and if the location bottleneck is this annular groove 4 not, the process that advances when bottleneck causes material to heap resistance because of the outer wall generation deformation of inner cap, and bottleneck often can't arrive the desired location.Left-hand thread closed type seedling cultivating bottle stopper preferably adopts macromolecular material, rubber especially, and therefore elastic rubber, good toughness can increase leak tightness and the service life of bottle stopper.Silica gel preferably, nontoxic pollution-free, weather resisting property is strong, is more suitable for seedling early growth.
During use, first inner cap 1 is filled in bottleneck, when bottleneck arrived annular groove 4 and enters in it, the crooked resilient flexible reverse cover 3 that overturns downwards again made resilient flexible reverse cover 3 distortion lock rings outside bottleneck, and as shown in Figure 2, this structure has the following advantages:
Originally the management and control size of outer crack is because adopting the left-hand thread form to reduce the management and control requirement, because of left-hand thread make it and bottleneck between better anastomose property is arranged.Because the resilient flexible reverse cover applies inside convergent force to bottleneck, therefore can greatly reduce bottle stopper in high-pressure sterilizing course because the poor rising of external and internal pressure is ejected, thereby improve the validity of disinfecting action; Adopt the left-hand thread form, make that inside face transfers outside face in the crack of former bottle stopper, thereby more be conducive to clean, sterilization and sterilization; In addition, bottle stopper global shape size is less, and the thickness attenuation of bottle stopper left-hand thread position bottle stopper is conducive to increase the mold well number and improves productivity effect, compare with the structure of the positive button-type bottle stopper of tradition, but economical with materials 20%, can be referring to Fig. 3.
