Abstract

The utility model relates to a multifunctional container cover. The utility model is characterized in that the multifunctional container cover is provided with an opening to the atmosphere, an opening to the container and an opening for suction, wherein, the opening to the container and the opening for suction, as well as the opening to the atmosphere and the opening to the container, are connected by a one-way valve, and the two one-way valves are connected by a lever; a disinfecting filter core is arranged in the air inlet of the opening to the atmosphere. The multi-function container cover, which can be used for various containers, such as packaged pressurized bottles, kettles, baby's bottle caps (with nipple), etc., has the advantages compared with the existing covers that the containers that the liquid in the container can have longer storage life after being used for many times; The gas composition contained in the liquid in the container can be prevented from escaping, thereby, the effect of the liquid can be kept constant; the puring or leaking of the liquid in the container can be prevented and the sanitation and the cleanness can be ensured.

Description

Multifunctional container cover

The utility model is a kind of container finish multipurpose lid.

In daily life, container is widely used, and container finish is indispensable with lid, and its function and safe ready have influence on daily life.

Known container closure element, as anker cap, kettle lid, milk bottle cap (comprising nipple) etc., lid is as the rate of outflow of closed container mouth or restriction liquid in containers.

The weak point of above-mentioned lid is that function singleness fails to give full play to its effect.As anker cap, once bottle cap opens, then contained gas can very fast effusion in the liquid beverage, the traveling comfort that has influence on mouthfeel and drink, owing to the direct contact of beverage and air or human body, harmful bacteria can be invaded in the beverage in addition, standing time can not be permanent, otherwise will go bad and can't drink; Also there is the shortcoming that is easy to go bad in kettle as being used to hold beverage; Feeding bottle (band nipple) except that the shortcoming that is easy to go bad is arranged, also spills institute's holding liquid in it easily, and is promptly unhygienic, uses also inconvenient.

The purpose of this utility model is the weak point that is to overcome existing container cover, and a kind of multifunction container lid is provided.

The purpose of this utility model can realize with following structure:

Cover at multifunction container and to be provided with three ports, be respectively logical vessel port, atmosphere entry, and suction inlet.Suction inlet communicates with vessel port by check valve respectively with atmospheric air port.The direction of two check valves is that in check valve entered container, liquid in container entered suction inlet by check valve to air by atmospheric air port.Two check valves have a lever to link to each other, and the valve block of lever or two check valves has certain flexibility, and the payload space of establishing breather check valve is S ₀, to balance pivot distance be L ₀, the payload space of fluid check valve is S ₁, to balance pivot distance be L ₁, should guarantee P ₀S ₀P ₁S ₁Establish a spring on one side at balance pivot, so that the first closure power of two check valves to be provided.An air filtration sterilization core can be installed before the breather check valve as required.Be example now: the liquid of the good required can of filling in the container with the beverage multipurpose lid, multifunction container is covered, be higher than ambient pressure, then the resultant moment of the suffered gaseous tension of two check valve sheet this moment as container inner pressure, impel two check valves all to close, liquid can't spill out; When container inner pressure was lower than ambient pressure, breather check valve was opened air inlet, and the fluid closed check valve, as the filter-sterilized core is installed on the free air diffuser, then entering air in the container by breather check valve, will be pure aseptic air, can not make in it liquid rotten; With the mouth suction inlet, the air-breathing negative pressure that causes impels the fluid check valve to open during use, and liquid outflowing container in the sucking hole, stops to fill suction, and check valve is promptly closed, and liquid does not have backflow.

This device can be used as anker cap, kettle lid, cover of a feeding bottle nipple etc., only changes with the connecting device of container and the auxiliary device that is beneficial to use to get final product.As the bottle cap that is used to suckle also needs additional nipple on suction inlet.

The utility model is compared existing container and is stamped following advantage:

1, container institute holding liquid still can prolong the pot-life behind repeated use.

2, after vessel port is opened and used, can prevent contained gas evolution in the liquid, the physics and chemistry effect of liquid is remained unchanged.

3, can prevent spilling of liquid in container, sanitation and hygiene.

Accompanying drawing, Fig. 1 are the cutaway view of multipurpose lid, wherein, and 1-lid, 2-lever, 3-fulcrum, 4-vessel port, 5-spring, 6-fluid check valve, 7-suction inlet (liquid outlet), 8-breather check valve, 9-atmosphere entry, 10-filter-sterilized core.

The utility model is described further below with reference to accompanying drawing:

Breather check valve 8 is linked to each other by lever 2 with fluid check valve 6, and fulcrum 3 is connected with lid 1, and suction inlet 7, admission port 9 communicate with vessel port 4 by two

check valves

6,8, and spring 5 provides the first closure power of two check valves.Filter-sterilized core 10 is to carrying out filter-sterilized by 9 inlet airs.6 and 8 valve block or 2 has certain flexibility, guarantee that 6 and 8 can unidirectionally respectively open, but container inner pressure can't make arbitrary one-way valve opens.4 with after vessel port is connected and fixed, and the specific requirement according to using adds some annexes, can normally use this valve.

Claims

1, a kind of multifunction container lid is characterized by, and has covered three ports, is respectively vessel port, atmospheric air port, suction inlet, and vessel port is communicated by check valve respectively with vessel port with suction inlet and atmospheric air port, and two check valves are linked to each other by lever.

2, multifunction container lid according to claim 1 is characterized by, and the filter-sterilized core is installed in admission port.

3, multifunction container lid according to claim 1 is characterized by, in balance pivot one side mounting spring.
