Abstract
The utility model provides a prevention of liquid leakage cosmetic containers, includes bottle and bottle lid, through threaded connection between bottle and the bottle lid, and its characterized in that bottle external thread is equipped with first lug, the internal thread of bottle lid is equipped with the second lug, and when bottle and bottle lid installation target in place, the spacing step of overlap joint formation can prevent effectively that cosmetic containers from taking place the weeping risk in the use between first lug and the second lug.
Description
Technical field
The present invention relates to a kind of liquid-leakage preventing cosmetics containers.
Background technology
Current cosmetics containers are generally made up of bottle and bottle cap, are threaded connection between bottle cap and bottle.The container of this structure can produce leakage under transport or vibration environment, and cause the pollution of bottle, affect perception, serious even affects normal sale.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, provide a kind of cosmetics containers, solve leakage problem.
Concrete technical scheme of the present invention is:
A kind of liquid-leakage preventing cosmetics containers, comprise bottle and bottle cap, be threaded connection between bottle and bottle cap, it is characterized in that described bottle external screw thread is provided with the first projection, the internal thread of described bottle cap is provided with the second projection, when bottle and bottle cap are in place, between the first projection and the second projection, overlap joint forms limited step.
Inventor's research draws why can produce leakage, and one of the main reasons is in existing cosmetics containers, and helicitic texture lacks spacing, and under vibrating conditions, screw thread can produce a little revolution, if things go on like this causes loosening of helicitic texture, causes leakage risk.This programme arranges limited step at the terminal position of helicitic texture, effectively prevents non-essential thread-whirling, can keep the tight of helicitic texture, prevent leakage.And the unlatching of the helicitic texture of this improvement needs larger active force, can prevent children from opening by mistake and eat by mistake.
Further, the shape of the first projection and the second projection is obtuse triangle, forms the first limited step.
Further, the shape of the first projection and the second projection is half arrow-shaped, containing a lead-in chamfered confined planes vertical with, forms the second limited step.
Further, the shape of the first projection is triangle, and the shape of the second projection is half arrow-shaped, containing a lead-in chamfered and a spacing inclined-plane.
Further, the bottom inside edge of described bottle cap is provided with some pits.
One of effect of pit is ventilation, balances and reduces the pressure reduction inside and outside bottle.Draw in inventor's research, two of the reason of leakage are caused to be to be threaded between traditional bottle bottle cap too to pursue sealing, and in use, because medium specific heat difference can cause pressure reduction inside and outside bottle, this pressure reduction will affect the helicitic texture that sealing is splendid originally greatly to a certain extent conversely, causes screw-threaded engagement form to damage.This programme, by arranging some pits bottom bottle cap, plays the effect of balance inside and outside differential pressure.
Further, described pit is a progressively intilted trapezoidal faces.Like this provide ventilative while can not cause expendable infringement to overall bottle cap housing.

Detailed description of the invention
Embodiment 1
As illustrated in fig. 1 and 2, container comprises bottle cap 1 and bottle 2, and containing internal thread 10 in bottle cap 1, external screw thread 11 is contained on bottle top.
Bottle cap 1 is provided with the pit 12 of trapezoidal faces, and described trapezoidal faces is that bottle cap bottom sides edge tilts to bottle cap inwall gradually, and inclination angle the best is 20-30 °.Be evenly distributed on bottom bottle cap.
As shown in Figure 3, the second projection 110 being distributed in female ends and the first projection 210 being distributed in thread termination position are all obtuse triangles to the first limited step structure, and angle the best in obtuse angle is 120-160 degree.
Containing guide surface 110a and confined planes 110b on second projection 110, containing confined planes 210a and 210b on the first projection 210.The summit of the first projection 110 and the second projection 210 is staggered, and the obtuse angle apex height of the first projection 210 is no more than the half of the second projection 110 hypotenuse height.
When threadingly structure covers tightly bottle 2 to bottle cap 1, the guide surface 210 of the first projection 210 connects with the guide surface 110a of the second projection 110, because bottle is all flexible material, continue to cover tightly and local dent can occur, when the peak of the second projection 110 crosses the first projection 210, the local dent of steel recovers, and forms the first stable limited step.
Embodiment 2
With embodiment 1 unlike, as shown in Figure 4, the second projection 111 and the first projection 211 are arrowhead form to this programme the second limited step structure.Second projection 111 is containing a guide surface 111a, a stop surface 111b and even surface 111c; First projection 211 is containing guide surface 211a, stop surface 211b and even surface 211c, and the effect of even surface is the intensity strengthening arrow portion, makes it to cause fracture because contact surface is too little.
First projection 211a and the second projection 111a forms the second limited step by stop surface.
Embodiment 3
Second projection 112 is arrowhead form, and containing guide surface 112a and spacing inclined-plane 112b, the first projection 212 is triangle, containing guide surface 212b and spacing inclined-plane 212a, forms the third limited step by two spacing inclined-planes.
Embodiment 4
Second projection 113 is arrow-shaped, containing an a guide surface 113a and confined planes 113b, the first projection 213 variation is a pit, and pit bottom is provided with even surface 213a, a sidewall 213b, as the position limiting structure corresponding with guide surface 113b, forms the 4th kind of limited step.
Claims (6)
1. liquid-leakage preventing cosmetics containers, comprise bottle and bottle cap, be threaded connection between bottle and bottle cap, it is characterized in that described bottle external screw thread is provided with the first projection, the internal thread of described bottle cap is provided with the second projection, when bottle and bottle cap are in place, between the first projection and the second projection, overlap joint forms limited step.
