Abstract

Dispenser head is connected with the valve seal of valve, and this valve can be used for being installed on the container that filling is assigned with product.A removable hood is housed on the device head, covers otch towards dispensing aperture.Between lid and the device head spring is housed.Cover and be provided with flexure strip, its bending end is closed dispensing aperture when resting guard.When lid was depressed, flexure strip was opened dispensing aperture before valve is opened.Otherwise, when pressure is released, is closed bonnet at valve and rises, close dispensing aperture.

Description

The dispenser head that product semiliquid, viscous or pasty state is used

The present invention relates to a kind of dispenser head that is used for product semiliquid, viscous or pasty state, can be in order to be installed on the container of filling this series products.It is installed on the valve, is connected with the sealing member of this valve, and is provided with pipeline, outside leading via dispense aperture along side direction.This dispenser head is suitable for the pressure of the pressured valve spring that contracts to be operated.

This dispenser head has been used to distribute the liquid product of aerosol shape for a long time.Thereafter, they also are applied to distribute the product of semi-liquid, viscosity or pasty state, for example food or cosmetic fat etc.So far still can not prevent a certain amount of product, after valve cuts out, still be retained in the dispenser head pipeline.The product that these are stayed in the distribution duct has the tendency that flows out to device head and container from dispensing aperture, or following and pollute or make dirty.

The present invention attempts to overcome these shortcomings, that is to say, avoids flowing out or dripping after container uses.

For this purpose, dispenser head of the present invention is characterised in that it comprises a lid, is installed on the device head and can vertically slides, and an otch towards dispensing aperture is arranged; A spring with compressive state work between device head and lid is arranged, and with the valve spring polyphone, its spring force is less than the power of valve spring; Also have one and lid bonded assembly spring leaf, when resting guard, close dispensing aperture, act on the at first mobile flexure strip of the pressure that covers, away from dispensing aperture.

When the pressure on acting on valve was released, valve cut out, and flexure strip is closed dispensing aperture then, had prevented that so the interior product of distribution duct that is retained in the device head from flowing out by above-mentioned aperture.When product time spent not, the product that also plays a part being filled in the device head distribution duct of closing of dispensing aperture is isolated from the outside, and that is to say, has prevented that the product that is filled in the above-mentioned pipeline from being polluted by extraneous dust.Product near dispensing aperture also can use subsequently.This is always not this situation when using known dispenser head.

Flexure strip can be in aggregates with the lid of synthetic material, also can make with metal or synthetic material or other material and be fixed to above-mentioned covering again.Preferably under tension force, act on the dispensing aperture, so that close this aperture effectively.

Accompanying drawing has illustrated a concrete device of the present invention by example, and drawing is described as follows:

Fig. 1 is the axial cutaway view of dispenser head;

Fig. 2 is the birds-eye view of above-mentioned dispenser head;

Fig. 3 is that the A of the device head among Fig. 1 is to view;

Fig. 4 is the view that is similar to Fig. 1, shows to cover to depress fully, but also compression of valve spring;

Fig. 5 shows the dispenser head after the valve spring compression.

The dispenser head 1 that synthetic material is made has vertical rod 2, and bar 2 is connected with valve seal 3 in being installed in cylinder valve body 4.Valve body 4 is synthetic material equally, and the packing seal 5 of compressible synthetic material is housed on the valve seat.Valve seal 3 rests on the packing seal 5 by spring 6.Valve body 4 diagrammatizes out at this.It can have various known form, and it can be connected on the container hole by known way with metal cup.The bottom of valve body 4 is provided with and enters hole 7, can be communicated with container.Device head 1 is provided with the transverse distribution spout 8 of duckbill, is connected with the distribution duct 9 of tapering slightly in it, and is communicated with distribution duct 10 by device head 1, and the outlet of pipeline 10 is landscape configuration on the height and position of valve insert 5.The cylindrical cover 11 of synthetic material is installed and is centered around on the device head.This lid 11 keeps leaving device head 1 by spring 12, and spring 12 is worked under compression between device head and lid, and spring force is basically less than the spring force of valve spring 6.Lid 11 has a horizontal rectangular aperture 13 for dispense spout 8 usefulness.Below dispense spout 8, the device head has a sloping bearing surface 14, and it is parallel with the ramped bottom surface 15 of spout 8 basically.Above-mentioned areal of support 14 has flange 16, to support elastomeric steel disc 17.This flexure strip 17 is by bending, and covers in 11 the groove 18 and fix by being clamped into.Clamping is to lean on the turned rim 19 of flexure strip bottom to realize.The free end of flexure strip 17 abuts against under tension force on the end of dispense spout 8 in the bending of 20 places, and the aperture of above-mentioned spout is closed.The top margin of dogleg section 20, just can be abutted against on the areal of support 22 of dispense spout 8 under the effect of spring 12 by replication.

Operating at hereinafter of dispenser head narrated with reference to Fig. 4 and Fig. 5.

Shown in arrow among Fig. 4, spring force at first is compressed than valve spring 6 little springs 12 basically when covering on 11 when pressure is applied to.Its effect is to cover 11 displacements that produce with respect to device head 1.11 displacement is covered in flexure strip 17 participations, and the dogleg section 20 of sheet is removed from the end of spout 8, like this dispensing aperture is opened.The part 20 of spring leaf is under the tension force, and its end leans against on the ramped bottom surface 15 of spout 8.

If continuing to be applied to, pressure covers on 11, its transverse opening 13 driving device heads 1 of The latter, thereby screw down valve spring 6, and movement of valve sealing member 3 makes it to leave packing seal 5, therefore, the product that is assigned with can flow through the pipeline 9 in pipeline 10 and the spout 8.

Pressure on lid 11 is released, because the rigidity of spring 6 is bigger than spring 12 basically, it is shutoff valve at first, recovers position shown in Figure 4 again.Pressure on lid 11 is all discharged, spring 12 will cover 11 with respect to 1 rising of device head, the thrust that the end 21 of flexure strip 17 is applied by means of flange 16, slip over the interior dip plane 15 on the spout 8, and owing to the crooked nose circle that slips over this face 15, it is closed in the aperture that moves past spout 8 then, as shown in Figure 1.

The present invention is not subjected to the limitation of described embodiment, and on the contrary, a large amount of structural changes is possible.Specifically, if use the bigger flexure strip 17 of rigidity, areal of support 14 just can be cancelled.This flexure strip can lean on simply with in the end insert cover 11 of its sloping portion and fix.

Flexure strip can be a non-metallic material, for example synthetic material, glass fibre or carbon or the like.

Flexure strip can be made with lid 11 integral body.In other words, areal of support 14 can constitute flexure strip, for this purpose, makes its end that vertically turns round be suitable for closing the aperture of spout 8.

If accurately make in the aperture of spout 8, perhaps dispose sealing member, just might obtain almost not have the leakage loss sealing to the distributing box aperture.

Dispenser head not necessarily needs to be provided with the spout that stretches out from lid.In this case, elastic sealing strip can be installed in the lid, between lid and device head.
