CN2075178U - Liquid returning type device for contain month - Google Patents

Abstract

The utility model relates to a liquid-returning type device for a container mouth. A container can not be polluted by liquid after the liquid is poured out. The liquid-returning type device for a container mouth comprises a main body formed by a liquid transferring pipe, a liquid-returning device, an inverted valve and a connecting body, and a cap formed by a cover and a plug in a connecting mode. The inverted valve is arranged on the pipe wall of the lowest connecting position of the liquid-returning device around the liquid transferring pipe. The connecting body and the utility model is an integral body, and the connecting body is connected with a container. When liquid is poured out, the inverted valve is made to close through the pressure caused by the liquid flowing along the liquid transferring pipe; after liquid pouring is completed, the residual liquid flows along the liquid-returning device to the inverted valve, the valve is made to open through the pressure, and the residual liquid returns to the container. The utility model is particularly suitable for the paces, such as the family, the restaurant, etc.

Description

Liquid returning type device for contain month

The utility model relates to a kind of liquid formula container mouth means that returns.Be specially adapted on the used liquid container in family and restaurant.

In people's daily life, laboratory and other place, when outwards falling from container behind the liquid, outside even the platform case placement container of container all can be subjected to the contamination of liquid, it is unhygienic again promptly to have wasted liquid, also can bring a large amount of work of scrubbing to people, articles for use are scrubbed in waste in a large number, and produce a series of disadvantageous consequences.Therefore design a kind of device that can address the above problem, attract much attention already, for example: the disclosed double hose family expenses of CN86205143U oil bottle mouth and CN86205104U liquid returning type bottle neck device.But these two kinds of devices all exist certain problem.For example: 1, all in various degree reduced liquid outlet.2, return port (pipe) is very thin, be easy to stop up, when long-time liquid or the container of falling during by accidental being knocked over, liquid will be from return port (pipe) slowly seepage flow come out and contamination container.3, return (collection) liquid bath and only play liquid collecting backflow effect, when reflux (pipe) hole plug or container were tilted placement, residual liquid can not return in the container, when falling liquid next time residual liquid will flow out back (collection) liquid bath and stain container.4, cover (lid) only plays dustproof effect, when container is knocked over by chance, and liquid will trickle out contamination lid and container.5, liquid returning type bottle neck device needs directed liquid, has brought inconvenience to use.

The purpose of this utility model is: design a kind of returning liquid formula container mouth means and adopting the Sheng liquid device of this device of addressing the above problem.

The utility model is achieved in that a kind of liquid formula container mouth means that returns, has a catheter on the top of said device, one around catheter and the annular that therewith constitutes return liquid bath, catheter exceeds and returns liquid bath, have in the bottom of said device one with seal of vessel bonded assembly connected body, catheter communicates with container by connected body, it is characterized in that the bottom of returning liquid bath tilts towards the catheter direction, on the catheter tube wall, have one with return the opening that liquid bath communicates, the opening part on catheter is provided with a non-return valve.In when falling liquid, the liquid of the catheter of flowing through produces pressure, and reverse stop valve is closed, fall behind the liquid, residual liquid is downward along catheter wall, and the liquid backflow device of flowing through is to reverse stop valve, residual liquid produces pressure opens reverse stop valve, and flows back in the container, and lid is promptly dustproof to prevent that again liquid from outwards trickling.

The utlity model has following characteristics: simple in structure, with low cost, easy to use, be easy to promote.

Below with reference to accompanying drawing the utility model is described in further detail.

Fig. 2 is the elevation cross-sectional view of the utility model concrete structure.

Fig. 3 is the longitudinal sectional drawing with the supporting lid of the utility model.

Fig. 4 is the longitudinal diagram of the utility model and container internal connecting type connected body device.

Fig. 5 is the longitudinal diagram of the utility model and container circumscribed connected body device.

Fig. 6 makes the longitudinal diagram of one for the utility model and container.

Fig. 7 is the utility model and the overall section-drawing of container bonded assembly.

Referring to Fig. 1 and Fig. 2, the top of returning liquid formula container mouth means 16 of the present utility model has a catheter 1, return liquid bath 2 around the annular that catheter also therewith constitutes, catheter exceeds and returns liquid bath, have in device 16 bottom one with seal of vessel bonded assembly connected body 5, by connector 5 catheter is communicated with container, the bottom of returning liquid bath 2 tilts towards catheter 1 direction, on the tube wall of catheter 1, have one with return the opening 3 that liquid bath 2 communicates, the opening part on catheter is provided with a non-return valve 4.Non-return valve connects with the valve that designs by hot pressing or pressure ring 8.

Non-return valve 4 of the present utility model adopts the plastic sheeting that is connected on the catheter, can certainly adopt other similar structures.Be provided with at catheter on the inwall of position of valve 4, have a plane 15 that cooperates with the plastic sheeting button.

Plastic sheeting 4 can hot pressing, and mode such as bonding is connected on the position that catheter 1 designed.

Connected body 5 can adopt circumscribed such as Fig. 1 and 2 with the connection mode of container, wherein has negative thread 6 on the connected body 5; Perhaps adopt internal connecting type, as Fig. 4, wherein have the fastening flange on the connected body, promptly can adopt to be threaded, also can adopt to be fastened and connected, being threaded is particularly suitable for the existing container that has had screw thread.For the container of not opening screw thread, connect in being particularly suitable for and be fastened and connected.

The lower end of catheter 1 of the present utility model has a closing membrane that can cut 13, sees Fig. 4, though closing membrane 13 is not shown in Fig. 1 and Fig. 2, those skilled in the art of the present technique are understood that, equally also closing membrane 13 can be set in its catheter 1 lower end.The device that adds this closing membrane is applicable to bottling liquid, when the user uses, film cut away gets final product.

The lid 17(that is used with container mouth means of the present utility model sees Fig. 3), removably cover (see figure 7) on container mouth means 16.Lid 17 has the bottom center that cup-shaped cover body 9, one stoppers 10 are suspended from cover body 9, and stopper 10 slightly is truncated cone shape, has one every liquid bath 11 at stopper near the position bottom the cover body.In case when cover body was squeezed, residual liquid beyond the Great Wall flowed in the cover body.The outside thread 7 that has on the outer wall of inner thread mouth 12 that has on the annular inner wall of cover body 9 and container mouth means 16 is tightly connected, and stopper 10 inserts to form in the catheters 1 and is tightly connected.

Lid 17 and container mouth means 16 also can adopt manner to be tightly connected.

Sheng liquid device (see figure 7) of the present utility model has the lid 17 of a container 14 and an airtight container, and container mouth means 16 is connected with the vessel port of container 14 by the negative thread 6 of its connected body 5, and lid 17 removably covers on container mouth means 16.

In the utility model technical solution, can be with material manufacture such as plastics or metals.

Described above is of the present utility model exemplifying, and it is conspicuous producing multiple variant in not exceeding scope of the present utility model.For example return liquid formula container mouth means and container is made the one (see figure 6) with of the present utility model.
