Description

Liquid packaging bottle and stopper thereof

Technical field

The present invention relates to a kind of liquid packaging bottle, relate in particular to the stopper used in the fluid application device of liquid packaging bottle.

Background technology

Prior art, embrocate the liquid packaging bottle of use, as liquid shoe polish, jacket oil, cleaning agent, lotion as the Packaging Bottle of safflower oil, floral water, psoriasis liquid medicine, beriberi medicine liquid, mosquito repellent wet goods all without the fluid application device of fluid steady and continuous.During use, or directly be poured on coated face, or be poured on the spreader of separately putting and embrocate on coated face again, lotion is to be poured on hand then to be smeared mostly, uses inconvenience also to waste liquid medicine.And in bottle, the liquid outlet quantity poured out of liquid is difficult to control, pour out liquid measure and often be greater than actual use amount and cause waste, and can't evenly smear, some liquid medicine volatilization absorbs fast, smear inhomogeneous also can drug effect.

For this reason, the contriver has designed a kind of fluid application device of liquid packaging bottle, realizes that liquid outlet quantity stablizes controlled and evenly smear, and the present invention relates to critical component wherein---stopper.

Summary of the invention

In order to solve above-mentioned technical matters, the purpose of this invention is to provide a kind of liquid packaging bottle and stopper thereof, this stopper with fastener, coordinate realize liquid outlet quantity stablize controlled, can evenly smear.

To achieve the above object, the present invention has adopted following technical scheme:

Stopper, fluid hole and endoporus with up/down perforation, stopper is formed with the positioning table terrace in the endoporus bottom, stopper is formed with the limit dais terrace in the endoporus upper end, fluid hole is arranged on limit dais terrace central authorities, the stopper upper end is coated with the applying head that the water permeability soft material is made, and applying head covers fluid hole.

As preferably, the water permeability sponge that described applying head is sheet or gauze net.

As preferably, described stopper bottom is the conical surface, the bottleneck interference fit of the stage casing of stopper and bottle, and the top circumference of stopper is provided with flange, and the bottleneck top of this flange and bottle offsets fixing.

As preferably, described fluid hole is the taper hole that up-small and down-big cone angle is 5～10 °.Described limit dais terrace is the conical surface that up-small and down-big cone angle is 150～170 °.The good fit of good fit, the limit dais terrace of fluid hole and fluid piston part and spacing shoulder is to guarantee key appropriate, stable, the fast speed liquid outlet quantity, the above-mentioned parameter scope is optimized scope, exceed above-mentioned scope, perhaps cause liquid outlet quantity too small, too much restive, or fluid is unstable.

As preferably, described stopper is Plastic Parts.

Liquid packaging bottle, comprise stopper as above.

The present invention is owing to having adopted above technical scheme, bottleneck at bottle arranges the fluid application device, the fastener that employing has the elastic support structure of spiral support arm coordinates with stopper, realize that the liquid outlet quantity of fluid application device stablizes controlled and evenly smear, this plug structure advantages of simple, make easily assembling quick, use easy to operate.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is made a detailed explanation.

Embodiment 1:

A kind of liquid packaging bottle as shown in Figure 1, comprise bottle 1 and bottle cap 4, the bottle mouth position of bottle 1 is equipped with the fluid application device, described fluid application device comprises stopper 3 and fastener 2, as shown in Figure 3, Figure 4, described stopper 3 has fluid hole 37 and the endoporus 34 of up/down perforation, stopper 3 is formed with positioning table terrace 35 in endoporus 34 bottoms, stopper 3 is formed with limit dais terrace 36 in endoporus 34 upper ends, fluid hole 37 is arranged on limit dais terrace 36 central authorities, stopper 3 upper ends are coated with the applying head 31 that the water permeability soft material is made, and applying head 31 covers fluid hole 37, as Fig. 5, shown in Fig. 6, described fastener 2 comprises steady ring 21, spiral support arm 22, spacing shoulder 23, fluid piston part 24 and pushing part 25, steady ring 21 is circular, a plurality of spiral support arms 22 distribute along steady ring 21 even circumferentials, spiral support arm 22 lower ends are fixedly connected with steady ring 21, spiral support arm 22 upper ends are fixedly connected with spacing shoulder 23, the center of top of spacing shoulder 23 is fluid piston part 24, the center of top of fluid piston part 24 is pushing part 25, wherein, the external diameter of the external diameter>pushing part 25 of the external diameter of the external diameter of steady ring 21>spacing shoulder 23>fluid piston part 24, fastener 2 is inserted in the endoporus 34 of stopper 3, steady ring 21 and positioning table terrace 35 location that offsets, and spacing shoulder 23 and limit dais terrace 36 offset spacing, and fluid piston part 24 is filled in fluid hole 37, and pushing part 25 offsets and contacts with applying head 31 bottoms.

In the present embodiment, so-called " upper and lower " is all Figure 1 shows that standard.Water permeability sponge or gauze net that described applying head 31 is sheet.Described stopper 3 bottoms are the conical surface 33, the bottleneck interference fit of the stage casing of stopper 3 and bottle 1, and the top circumference of stopper 3 is provided with flange 32, and this flange 32 offsets fixing with the bottleneck top of bottle 1.Described fluid hole 37 is taper holes that up-small and down-big cone angle is 5～10 °, and fluid piston part 24 is frustums that up-small and down-big cone angle is 1～4 °.Described limit dais terrace 36 is conical surfaces that up-small and down-big cone angle is 150～170 °, and spacing shoulder 23 is frustums that up-small and down-big cone angle is 70～80 °.Described fastener 2 has three spiral support arms 22.The part that the end face of described pushing part 25 is sphere.Described stopper 3 and fastener 2 are Plastic Parts.Described bottle 1 is conical flask.As shown in Figure 2, described bottle cap 4 has negative thread 41, annular projection 42 and groove 43, negative thread 41 matches with the external thread of bottleneck of bottle 1, annular projection 42 is arranged on bottle cap 4 inner tops, annular projection 42 central authorities form groove 43, when bottle cap 4 is tightened on the bottleneck of bottle 1, annular projection 42 is pushed against the flange of stopper 3 32 on the bottleneck top of bottle 1, and the applying head 31 at stopper 3 tops is inserted in groove 43.
