Abstract

The invention relates to a ventilating bottle and relative production, wherein said bottle comprises main body whose open end is screwed with rotation cover with internal absorber; the cover covering the absorber and covered on the rotation cover; the bottom of bottle has silica gel ventilating valve; the valve is formed by annular edge fused with bottom, nipple points protruded on the annular edge, and ventilating cuts on the points. When the bottle is passive pressure, air will open the ventilating cut to enter into bottle; when the pressures are balance, the cut will automatically close, to form ventilating but not leaking bottle. The invention can combine PC milk bottle and medical silica gel ventilating valve, that putting bottle into mould section of silica gel ventilating valve to be fused together.

Description

Air-permeable bottle and manufacturing process thereof

Technical field

The present invention relates to the air-permeable bottle of a kind of feeding aqueous liquid foodstuff or drink and adopt the feeding bottle of PC material and the air-permeable bottle manufacturing process that medical silica-gel fuses.

Background technology

Like product on the market is because the restriction of structure and the restriction of technology at present, also there are not the feeding bottle and the medical silica-gel of PC material to be welded together product, and more can not fundamentally solve the whole negative pressure problems that produced when feeding bottle is sucked, limitation is bigger, breaks through also when sucking continuously that negative pressure is concentrated and can not balance.

Summary of the invention

The objective of the invention is to overcome above-mentioned the deficiencies in the prior art part and a kind of environmental protection is provided, ventilative and suck and when causing negative pressure when a bottle internal cause, air is under atmospheric effect, forcing the ventilative valve otch of silica gel to be opened enters in the bottle, replenish negative pressure in the bottle rapidly, when bottle internal gas pressure and external atmosphere pressure balance, the otch SELF CL on the ventilative valve of silica gel forms a kind of ventilation and watertight air-permeable bottle that is made of the ventilative valve of silica gel.Another object of the present invention provides that the bottle of PC material and the ventilative valve of medical silica-gel material are fused to be the air-permeable bottle manufacturing process of one.

Purpose of the present invention can reach by following measure:

This air-permeable bottle comprises that bottle, bottle open end screw the swivelling cover of built-in suction nozzle, covers suction nozzle and is fastened on cover body on the swivelling cover, and its special character is: the bottle diapire welding one silica gel valve of breathing freely; The ventilative valve of described silica gel by with the ring edge of welding at the bottom of the bottle, ring edge on the ventilative otch that has on the milk head marble point, marble point that are convexly equipped with form.

The ventilative valve of described silica gel is made by medical transparent silica gel material.

Purpose of the present invention can also reach by following measure:

The technology of this manufacturing air-permeable bottle, its special character is that it comprises the steps:

When (1) beer is moulded, bottle is placed in the mold cavity of silica gel vent valve;

(2) bottle and the ventilative valve of silica gel are fused into integrative-structure.

The present invention has following advantage compared to existing technology:

1. the ventilative valve fiduciary level height of silica gel is ventilative water-tight again, sucks more laborsaving, free and relaxed.

2. product adopts nontoxic, harmless material to make, and meets U.S. FDA and European EN71 hygienic standard.

3. when placing, cover translucent cover, can prevent that the silica gel suction nozzle from leaking with contaminated.

4. product adopts the design of hommization protectiveness, and health is water-tight, and is safe and reliable, easy to use.

5. suck and water-tight when standing upside down, unpick and wash conveniently.

The specific embodiment

The present invention is further detailed in conjunction with the accompanying drawings below:

See also shown in the accompanying drawing structure of air-permeable bottle: the open end of ventilative bottle 4 screws the swivelling cover 3 of built-in suction nozzle 2, and covering suction nozzle 2 and being fastened on the swivelling cover 3 is translucent cover 1.The centre is provided with the otch 50 ventilative valve 5 of ftercompction and the watertight silica gel of ventilating automatically, and encapsulate when ventilative bottle 4 is subjected to hydraulic pressure and pushes, can prevent effectively that otch 50 from opening and cause and leak and liquid seepage at the bottom of the bottle at the bottom of the bottle.The ventilative valve 5 of described silica gel by with the ring edge 52 of welding at the bottom of the bottle, ring edge 52 on the ventilative otch 50 that has on the milk head marble point 51, marble point 51 that are convexly equipped with form, the silica gel medical transparent silica gel material of valve 5 employings of breathing freely is made.

Make the technology of above-mentioned air-permeable bottle, comprise the steps:

When (1) beer is moulded, bottle 4 is placed in the mold cavity of silica gel vent valve 5;

(2) the ventilative valve 5 of bottle 4 and silica gel is fused into integrative-structure.

Use: when when children suck, the suction nozzle 2 of beverage being housed, beverage in the bottle 4 is reduced because of sucking, space in the bottle 4 correspondingly increases, thereby produces negative pressure, and air is under atmospheric effect, force the marble point place otch 50 on the ventilative valve 5 of silica gel to be opened, gas is entered in the bottle 4, replenish negative pressure in the bottle 4, when air pressure in the bottle 4 and external atmosphere pressure balance, otch 50 SELF CL at marble point place on the ventilative valve 5 of silica gel are to reach ventilation and watertight purpose.

The above only is preferred embodiment of the present invention, and all equalizations of being done according to claim scope of the present invention change and modify, and all should belong to the covering scope of claim of the present invention.

Claims (3)

1, a kind of air-permeable bottle comprises that bottle, bottle open end screw the swivelling cover of built-in suction nozzle, covers suction nozzle and is fastened on cover body on the swivelling cover, it is characterized in that: the bottle diapire welding one silica gel valve of breathing freely; The ventilative valve of described silica gel by with the ring edge of welding at the bottom of the bottle, ring edge on the ventilative otch that has on the milk head marble point, marble point that are convexly equipped with form.
