Abstract
The utility model relates to a vacuum milk bottle which comprises a bottle body, a bottle cap and an inner seal ring. The bottle cap is provided with an air vent. An annular groove is formed in the bottle cap along the periphery on the outer side of the air vent. An outer seal ring is further arranged and provided with a sealing cap. The side wall of the sealing cap can be in close fit with the side wall of the annular groove of the bottle cap. By adopting the scheme, the vacuum milk bottle achieves the function of retaining freshness locally, avoids secondary contamination caused when milk, breast milk and other products which need to be sealed in the vacuum milk bottle are poured in and out repeatedly, and is simple in structure and easy and convenient to operate.
Description
Technical field
This utility model relates to a kind of vacuum feeding bottle.
Background technology
In modern society, no matter be all kinds of milk product foster nursings or breast-fed, the feeding bottle that the baby uses is more and more universal.if mother's baby milk is not enough, the general practice is that milk powder and warm water are injected baby bottle by a certain percentage, covering cover has the bottle cap of nipple, after shaking up, suck to the baby, but the baby sometimes eats up or while eating, has just slept, often can be left part milk in feeding bottle, due to can not be fresh-keeping for a long time after milk powder bath, at this moment, milk remaining in feeding bottle is outwelled, but obviously can cause unnecessary waste, milk in feeding bottle is poured in Antistaling container, evacuation is preserved, again milk is again poured in feeding bottle and used while waiting until next baby's hunger, but this mode of operation very easily causes secondary pollution, affect milk matter or baby and healthy.In like manner, if mother baby can't be at any time squeezes breast milk to drink to the baby because of working or other reason, so common way is, first milk is clamp-oned Antistaling container, wait until afterwards again with after it heating, pour in feeding bottle and drink to the baby, but same result is, so repeatedly buy and sell, also as easy as rolling off a log generation secondary pollution.
Summary of the invention
For above-mentioned deficiency, the purpose of this utility model is intended to directly to have the baby bottle structure now and redesigns, make it have the freshness seal function, and features simple structure, concrete scheme is as follows: a kind of vacuum feeding bottle comprises body, bottle cap and inner seal ring, it is characterized in that, described bottle cap is provided with passage, and described bottle cap forms annular groove along the outboard peripheries of passage; Also be provided with exterior seal ring, described exterior seal ring is provided with sealing cap, the sidewall of described sealing cap can with the annular groove sidewall tight fit of bottle cap.Corresponding matching on the inner edge of exterior seal ring and the physical dimension of bottle cap and structure, exterior seal ring is made with elastomeric material, it is out of shape to open slightly pulls, and exterior seal ring can be buckled on the outer rim of bottle cap.
Further scheme also comprises, the lateral margin top of described sealing cap is fixed with disappointing switch knob.When if feeding bottle need to be exitted, can will lose heart the switch knob left and right pull, because disappointing switch knob and sealing cap are connected, to lose heart and slightly pull about switch knob, so, space produced between the medial wall of sealing cap and the lateral wall of annular groove, air is able to enter in bottle by passage from here, thus deblocking.
Further scheme also comprises, also is provided with the top cover that can be buckled on bottle cap, and it is protruding that the inwall top of described top cover is provided with top.The outer wall tight fit of top cover inwall lower end and bottle cap, when slightly firmly cover buckle is on bottle cap with top cover, the frictional force that the outer wall of itself and bottle cap produces, to make top cover keep being in the mutual stable state that presses with bottle cap, and this moment, push up the protruding top that will contact sealing cap, sealing cap is pushed under annular groove, thus the enhanced leaktightness function.
By such scheme, successfully realized fresh-keeping on the spot function, avoided the goods of the needs such as the milk in feeding bottle or breast milk sealing are repeated to pour into the secondary pollution of pouring out, and simple in structure, easy and simple to handle.
Description of drawings
Fig. 1 is cross-sectional schematic before the embodiment evacuation;
Fig. 2 is embodiment evacuation cross-sectional schematic;
Fig. 3 is cross-sectional schematic after the embodiment evacuation;
Fig. 4 is embodiment A section enlarged drawing;
Wherein, 1 is body, and 2 is bottle cap, and 3 is top cover, and 4 is inner seal ring, 5 is exterior seal ring, and 6 is evacuator, and 21 is passage, and 22 is annular groove, and 23 is annular flange flange, 31 is protruding for top, and 51 is sealing cap, and 52 are the switch knob that loses heart, and 53 is annular groove, and 54 is dowel.
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is further described.
As shown in Figures 1 to 5, during assembling, first with the bottom of inner seal ring 4 pads at bottle cap 2, then will pad the internal screw thread of the bottle cap 2 of interior sealing 4 tightens facing to the external screw teeth screw-in of feeding bottle, inner seal ring 4 is compressed between bottle cap 2 and body 1, fill the air gap between the two, intercepted air and entered thus.Annular groove 53 is located at exterior seal ring 5 lateral margin bottoms, and annular flange flange 23 is located at the outside of bottle cap 2, and exterior seal ring 5 is slightly stretched, and makes it distortion, the annular groove of exterior seal ring 5 53 bags can be buckled on the annular flange flange 23 of bottle cap 2, thereby exterior seal ring 5 is anchored on bottle cap 2.Dowel 53 is located between the lateral margin and sealing cap 51 of exterior seal ring 5, and dowel 53 is connected exterior seal ring 5 with sealing cap 51, leave space between dowel 53, so that air passes through.
during evacuation, the evacuated housing of evacuator 6 is aimed at the lateral border of exterior seal ring 5, start vacuum pump, so the air in feeding bottle will be successively via passage 21, gap between sealing cap 51 and annular groove 22 and the space between dowel 53, discharge after entering evacuator, thereby make the air in feeding bottle fewer and feweri, produced atm difference with the external world, this also makes the sealing cap 51 downward sedimentations of pressure differences, the sidewall of sealing cap 51 stretches into to interior the continuing of annular groove 22, and because annular groove 21 cross sections slightly are trapezoidal, wide at the top and narrow at the bottom, so, sealing cap 51 more moves down, it is tighter that it coordinates with the sidewall of annular groove 22, the sidewall of final sealing cap 51 touches the bottom of annular groove 22, completely cut off so feeding bottle is inside and outside, feeding bottle is sealed, and the inner top of sealing cap 51 also can touch and block at this moment passage 21, thereby the effect of enhanced leaktightness.
In addition because sealing cap 51 can constantly descend along with the process of evacuation, so by the transparent evacuated housing of evacuator 6, decline process that with the naked eye can direct observation sealing cap 51, can intuitively understand the progress degree of evacuation.
Evacuation can cover top cover 3 after finishing again, and protruding 31 of top in top cover 3 directly is against on sealing cap 51, has played the effect of enhanced leaktightness.
During as the need deblocking, take off top cover 3, the metal plate button 52 left and right metal plates that will lose heart are moving, so air is again again successively by gap, passage 21 between space, sealing cap 51 and annular groove 22 between dowel 53, enter in feeding bottle, the inside and outside air pressure difference of feeding bottle constantly reduces, and sealing cap 51 will constantly rise and finally set back, and feeding bottle is able to deblocking.
Need to prove, embodiment explains to of the present utility model, and any equivalent transformation that meets the technical program substantial principle all should be within protection domain of the present utility model.
