Abstract
The utility model discloses a rotary bottle cap with insertion pipe, which consists of a cap body, a sharp spiny insertion pipe and an outer cover, the insertion pipe that can be moved along in axial direction is plugged into the pipe orifice of the cap body, the outer cover with upper and lower two internally screwed sections is bell-socketed outside the insertion pipe, while the screw of upper and lower two sections inside the outer cover matches with the screw of pipe mouths of insertion pipe and cap body in the same rotation direction separately, wherein the screw-pitch of the matched threads of the upper section and the insertion pipe is bigger than that of the matched threads of the lower section and the cap body pipe mouth, thus the utility model is made to be with rational structure, convenient usage, simple manufacturing technology, low cost, and so on characteristics.
Description
Technical field
The utility model relates to a kind of special supporting bottle cap that is used on the beverage bottle, especially a kind of fruit special-purpose bottle cap of suckling.
Background technology
Traditional beverage bottle, it is to carry out sealed package with bottle cap specially after in its bottle beverage being housed.Occurred a kind of special supporting bottle cap that is used on the fruit feeding bottle recent years on the market, this Fruit milk bottle cap has intubate, in use, intubate is screwed off, and punctures the film that seals on the bottleneck, directly drinks for children.This Fruit milk bottle cap includes lid, intubate, and spiral covers etc. spin by the screw thread on intubate and the bottleneck, drive the intubate rotation by spiral cover and move up and down.But the Bottle cap structure of this structure is comparatively complicated, and result of use is not good.
Summary of the invention
The purpose of this utility model is to provide a kind of bottle cap of rotary plug-in type, it includes lid, the intubate and the outer cover of band spine, be plugged with axially displaceable intubate on the described lid mouth of pipe, in being socketed with, intubate is shaped on the outer cover of two sections screw thread outward, and the two sections screw thread in the outer cover respectively with intubate and the lid mouth of pipe screw thread fit with identical rotation direction, wherein the screw thread spiral shell square of epimere and intubate threads engaged is greater than the screw thread spiral shell square of hypomere and lid mouth of pipe threads engaged.
The spiral shell square of the screw thread of described outer cover epimere and intubate threads engaged is two times of screw thread spiral shell square of hypomere and lid mouth of pipe threads engaged at least, and spins mutually with minus thread.
Be provided with that rotate, that cooperatively interact the mutually concavo-convex straight trough of restriction between the described intubate that spins respectively by outer cover and the lid mouth of pipe separately.
The upper interior end of the described lid mouth of pipe is provided with the protruding circle of undergauge.
The utlity model has rational in infrastructure, easy to use, characteristics such as manufacture craft is simple, and cost is low.

Fig. 3 is a cannula structures scheme drawing of the present utility model.
Fig. 4 is a cover structure scheme drawing of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, the utility model mainly is made up of lid 1, intubate 2 and outer cover 3.The bottom of intubate 2 cooperatively interacts by the concavo-convex straight trough 4 of periphery and the concavo-convex straight trough 6 on the lid mouth of pipe 5 inwalls, moving axially about it is plugged on and also can does in the lid mouth of pipe 5.The periphery wall of the lid mouth of pipe 5 is provided with minus thread 7, sees accompanying drawing 2.And on the epimere periphery wall of intubate 2, also be provided with minus thread 8, and see accompanying drawing 3, and the spiral shell square of the minus thread on the intubate 28 is greater than the spiral shell square of the minus thread on the lid mouth of pipe 57, in the present embodiment, the former spiral shell square is 3.5, the latter is 1.25.The described outer cover 3 that is nested with on the intubate 2 and the lid mouth of pipe 5 is seen accompanying drawing 4, its inner hole wall be shaped on two sections each with the intubate 2 and the lid mouth of pipe 5 on the screw thread 9,10 of threads engaged.Because epimere screw threads 9 match with screw thread 8 on the intubate 2 in the outer cover 3, and its hypomere screw thread 10 matches with screw thread 7 on the lid mouth of pipe 5, the former spiral shell square is greater than latter's spiral shell square, through rotation in the same way, intubate is moved down, puncture the purpose of sealing film on the bottleneck, move to the screw thread disengagement as outer cover 3 is continued up rotation thereby reach, can take off outer cover 3, and can conveniently drink.Deviate from from the lid mouth of pipe 5 for fear of intubate 2, the utility model is provided with the protruding circle 11 of undergauge in the upper interior end of the described lid mouth of pipe 5, during assembling, intubate 2 is pressed fit into the lid mouth of pipe 5 get final product.
