Abstract

The utility model provides a kind of oral liquid straw, and surface is evenly equipped with 5 to 12 ribs, the bottom between adjacent corner angle be equipped with axially through groove.The cross-sectional shape of the groove is arc-shaped, rectangle, trapezoidal or triangle.Compared with the 5 ribs/12 rib oral liquid straws generally to circulate currently on the market, the oral liquid straw of the utility model does the design of a groove on the basis of general oral liquid straw by the bottom between adjacent corner angle, to increase the gap between suction pipe and rubber plug, breaking vacuum state greatly improves use feeling.The oral liquid straw of the utility model can be well matched with from different rubber plugs, no matter medical fluid can easily suck medical fluid whether thick very much.

Description

A kind of oral liquid straw

Technical field

The utility model relates to suction pipe fields, and in particular to a kind of oral liquid straw.

Background technique

Oral liquid straw is one kind of suction pipe, is mainly used for the intake of oral solution.Oral liquid straw material be generally PP or Person PE.It is characterized in that the surface of suction pipe is uniform-distribution with five to 12 ribs, it is preferred with eight ribs, referring to Fig. 1.These ribs B with The vertical grade separation of orifice plane is inhaled, in order to penetrate aluminium lid and aluminium lid liner (rubber plug), makes imbibition smoothly.

Oral liquid straw is siphoned away partial air against suction pipe when use, will cause pipe internal pressure with atmospheric pressure principle Become smaller by force, and for equilibrium air pressure, atmospheric pressure will force liquid in pipe to rise.When stopping suction, liquid in pipe decline, pressure Balance is just returned to by force.Because oral liquid straw surface has rib air is easy to be extruded.

5 ribs generally to circulate currently on the market/12 rib oral liquid straws, though it under general use conditions can be with epispastic Liquid, but when for sucking some biggish oral solutions more elastic than rubber plug denser and used, due to empty between rubber plug and suction pipe Gap is too small to result in vacuum state, it is difficult to which sucking liquid, user experience are poor.It can only be pried open in the case where being difficult to be sucked out Bottle stopper is easy to pollute medical fluid in this way.

Summary of the invention

For solve existing oral liquid straw draw it is some than denser rubber plug oral solution medical fluid when, suction that cannot be much smoother Out the technical issues of medical fluid, the utility model provides a kind of oral liquid straw, by changing suction pipe angular shape, to increase suction Gap between pipe and rubber plug, breaking vacuum state, no matter can easily be inhaled whether from the cooperation of different rubber plugs and thick medical fluid Eat medical fluid.

The technical solution that the utility model provides in order to achieve the above objectives is: a kind of oral liquid straw, the pipe including open at both ends Body, the outer surface of tube body are evenly distributed with 5 to 12 ribs, and inner circumferential surface forms the circular cavity passed through for sucking medical fluid, Be characterized in that, the bottom between adjacent corner angle be equipped with axially through groove.

The design of groove increases the gap between suction pipe and rubber plug, and outside atmosphere can add to bottle in time when sucking In, vacuum will not be formed in bottle, greatly improve use feeling.

In order to manufacture simplicity, the cross-sectional shape for designing the groove is arc-shaped, rectangle, trapezoidal or triangle.

When the corner angle of suction pipe are 5, designing the groove has 1 to 5.Number of recesses at least one, increase groove Quantity increases the void area between suction pipe and rubber plug, is more advantageous to medical fluid and sucks.

When the corner angle of suction pipe are 5~12, designing the groove has 1 to 12.Number of recesses at least one, increase Number of recesses increases the void area between suction pipe and rubber plug, is more advantageous to medical fluid and sucks.

In order to facilitate use, the one end for designing the oral liquid straw is equipped with tip.

In order to guarantee the intensity and puncture resistance of pipette tip, the folder in the tip-tilt face and tubing length direction is designed Angle is 30~60 degree.Angle is too small, and tip strength is low, and the excessive then puncture resistance of angle is poor.

The utility model has the beneficial effects that compared with the 5 ribs/12 rib oral liquid straws generally to circulate currently on the market, The oral liquid straw of the utility model does a groove by the bottom between adjacent corner angle on the basis of general oral liquid straw Design, to increase the gap between suction pipe and rubber plug, breaking vacuum state greatly improves use feeling.The utility model takes orally Liquid straw can be well matched with from different rubber plugs, no matter medical fluid can easily suck medical fluid whether thick very much.

Specific embodiment

Hereinafter, referring to attached drawing, by taking the oral liquid straw with 8 corner angle as an example, to the mouth of the utility model embodiment Liquid straw is taken to be illustrated.

(1) embodiment 1

Referring to Fig. 2 to Fig. 3, a kind of oral liquid straw, the tube body 1 including open at both ends, the outer surface of tube body 1 is uniformly distributed There are eight corner angle B, inner circumferential surface forms the circular cavity 3 passed through for sucking medical fluid, one end edge and the tube length L of tube body 1 Tip 21 is cut in 45 degree of direction, i.e. the included angle A of the inclined surface (cutting face) at tip 21 and tube length direction is 45 degree. In other embodiments, included angle A can also be chosen between 30 degree to 60 degree.Tip 21 is for puncturing aluminium lid and aluminium lid liner.? Between adjacent corner angle B1 and B2, bottom offers circular groove 01 along the perforation of suction pipe axial direction, and circular groove 01 is set There is one.

(2) embodiment 2

Referring to Fig. 2 and Fig. 4, embodiment 2 and embodiment 1 are essentially identical, the difference is that, groove 02 is in rectangle, It is symmetrically arranged with 2.

(3) embodiment 3

Referring to Fig. 2 and Fig. 5, embodiment 3 and embodiment 1 are essentially identical, the difference is that, groove 03 is trapezoidal, It is laid with 4.

(4) embodiment 4

Referring to Fig. 2 and Fig. 6, embodiment 4 and embodiment 1 are essentially identical, the difference is that, groove 04 is in triangle Shape is symmetrically arranged with 6.

(5) embodiment 5

Referring to Fig. 2 and Fig. 7, embodiment 5 and embodiment 1 are essentially identical, the difference is that, groove 05 is in circular arc Shape is laid with 8.

It is to keep suction pipe beautiful and easy to process that groove, which is symmetrical arranged, and asymmetric design has no effect on the usability of suction pipe Energy.The above suction pipe uses PE or PP material, by extruding machine continuous extrusion, changes the shape of extruding machine outlet extruding mould Special-shaped suction pipe required for the utility model can be obtained.
