Description

A kind of eyedrops packing plastic bottle
Technical field
The utility model belongs to medical packaging bottle field more particularly to a kind of eyedrops packing plastic bottle.
Background technique
Document number is that the Chinese patent of CN105691937A discloses a kind of eye drops Packaging Bottle, including cylindrical bottle Body, the front end of bottle body form minim pipette, a bottle cap are arranged with outside minim pipette;Piston group is slidably connected in the bottle body Part;The piston component includes piston body and piston rod;The piston rod outer wall forms external screw thread, the bottle body nut Part;The nut piece forms internal screw thread;The nut piece includes grafting circle, and supports side outside;The grafting ring outer wall at Type has clamp, and the bottle side wall forms bayonet;Bar shaped bayonet is formed on the piston rod, is equipped in bar shaped bayonet Driving lever;The bar shaped bayonet forms latch;The driving lever includes driving lever body and positioning plate and conical head, the taper Shifting block is formed on head, the conical head and the outer edge forming that supports have plush copper;Outer support on side of the nut piece forms protrusion.It should For scheme when single stirs shifting block, the eyedrops of extrusion is only the amount of a drop, is easy to use.But above scheme user uses When, each dropping liquid can only ooze the medical fluid of a drop, be unable to control the amount for oozing medical fluid every time, and for squeezing out being equipped with for eye drops Externally threaded piston rod is exposed to except bottle body, so that the appearance of Packaging Bottle is poor.
In addition document number is the Chinese patent literature of CN105708616A, CN105662855A and CN205707950U Similar packaging bottle structure is disclosed, the disadvantage is that too small (the general eyedrops bottle of button part size for squeezing out eyedrops Diameter all within 30mm, the part of button just seems very little in contrast), button part pressing exists tired in actual use Difficulty, and button part intensity is inadequate, is easily damaged.If can make in bottle body in addition, being accidentally hitting to button part before Kaifeng Pressure rise will lead to the eyedrops at Kaifeng and spray, influences user experience.In addition piston portion is not used or makes in eyedrops The rear end of bottle body is predominantly located in when with small part, so that the structural strength of Packaging Bottle entirety is poor, under external force The case where being likely to occur damage and eyedrops caused to reveal.
