CN201961653U - Bottle cap with pressure head - Google Patents

Abstract

The utility model discloses a bottle cap with a pressure head, which comprises a shell, wherein the upper end of the shell is provided with a limit clamp ring for limiting the pressure head in the shell, the lower end of the shell is connected with an inner cover matched with a bottle body, an elastic body is connected between the pressure head and the inner cover, the lower end of the elastic body is connected with a dropper communicated with the elastic body, and the upper end surface of the limit clamp ring is provided with two symmetrically arranged U-shaped gaps. The pressure head is pressed to extrude the elastic body downwards so as to make the inner part of the dropper communicated with the elastic body present in negative pressure, so that sucking liquid is facilitated. Because the pressing stroke of the pressure head is fixed, the suction amount of the dropper is basically same each time, a user only needs to press the pressure head to make the liquid flow out, and the two U-shaped gaps enable the user to press the pressure head comfortably with less effort.

Description

The bottle cap that has pressure head

Technical field

The utility model relates to a kind of soup bottle cap, but specifically is a kind of bottle cap that has pressure head of dosed administration.

Background technology

For liquid or half liquid half medicaments such as emulsion, emulsifiable paste of state admittedly, generally all adopt traditional bottle cap at present, need take off bottle cap during use earlier, the inclination bottle is poured out medicament, builds bottle cap then.The shortcoming of this medicine bottle is: the dose of pouring out need be estimated control, or with measuring cup control, is difficult to accurate grasp, and the amount that can produce taking-up has error, influences result of use; In addition, in the medicament, have small amount of liquid to flow down along bottleneck unavoidably in pouring out bottle, not only use inconvenience, there is health concerns in health not enough.

In order to address this problem, the someone has applied for China Patent No. 200920218351.1, and name is called the dosed administration bottle that has the quantitative drop pump, and it includes shower nozzle, spiral cover, the pump housing, pump casing cover, bar, base, piston, spring, spring pedestal and check valve; Wherein said bar is located in the pump housing, be arranged with described piston on the bar, one end of bar is formed with described base, bar is provided with a plurality of grooves, the described base of one end of bar is connected with described spring, the other end of this spring is provided with described spring pedestal, the below of this spring pedestal is provided with described check valve, and described pump casing cover is set in the port of the described pump housing, and described spiral cover is set on this pump casing cover, the top of this spiral cover is provided with the hole, be inserted with shower nozzle in this hole, this shower nozzle is connected with described bar, by the extruding pump housing, can from medicine bottle, take out the liquid that needs, also health easy to use quantitatively.But with regard to fewer medicine, as long as extract small volume of solution, and when aiming at a certain Special Thing, this constructed products obviously will inconvenient operation and consumption also waste too much during use for total amounts such as some eyedrops own.

Summary of the invention

The utility model has mainly solved complex structure in the prior art, and consumption is wasted too much, uses deficiencies such as inconvenience, and a kind of dose of can not only controlling is provided for this reason, operates convenient and swiftly again, simple in structure, pushes a kind of easily bottle cap that has pressure head.

Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of bottle cap that has pressure head, comprise housing, the housing upper end has spacing snap ring that pressure head is limited in the housing, the lower end of housing is connected with the inner cap that matches with bottle, be connected with elastic body between pressure head and the inner cap, described elastomeric lower end is connected with the dropper that communicates with it, and there is a U-shaped breach upper surface of described spacing snap ring.The user makes the dropper inside that is connected with elastic component present negative pressure, so that imbitition as long as push elastic component downwards by pushing pressure head.By the positive stop strip at pressure head two ends, make pressure head press down stroke and fix, therefore the uptake of each dropper is basic identical, and the user only need control the stroke of pushing pressure head, amount that just can the controlling liquid outflow.

As preferably, described U-shaped breach is two and is symmetrical arranged.Two breach form a cavity, and the size of this cavity and human body mother refer to that size matches, and during use, whole thumb all is embedded in the middle of the cavity, adopts this structure, and the user is pushed conveniently, and are laborsaving.

Described elastic body can be sponge, spring, and as preferably, elastic body is a rubber elastomer, and this elastic body is Ω shape, and elastomeric lower end inner peripheral surface is provided with the inner groovy that connects dropper, and outer circumference surface is provided with the outer groove that connects inner cap.The inner cap upper surface have with elastic body on the flange that matches of outer groove, match with outer groove by flange, elastic component be fixed on inner cap upper end, the dropper upper end have with elastic body on the edge clipping that matches of inner groovy, match by edge clipping and inner groovy, dropper is linked to each other with elastic component.

As preferably, described elastic component upper surface also is provided with projection, is provided with the guiding projection that matches with projection in the pressure head.Described projection is a stress point, and the user exerts pressure to pressure head, and pressure is delivered on the projection by guiding projection, pushes laborsaving convenience.

As preferably, described pressure head both sides are provided with positive stop strip.This positive stop strip equals the stroke distances that pressure head presses down to the distance of inner cap, adopts this structure, and the control pressure head presses down stroke, avoids excessively pressing down making the elastic component distortion, influences service life.

As preferably, described pressure head outside face is dome shape.Adopt this structure, it is comfortable that the user is pushed.

The beneficial effects of the utility model are: push elastic component downwards by pushing pressure head, make the dropper inside that is connected with elastic component present negative pressure, so that imbitition.Because pressure head presses down stroke and fixes, the uptake of therefore each dropper is basic identical, and the user only need push pressure head, and liquid is flowed out; Two U-shaped breach, it is comfortable that the user is pushed, laborsaving.
