Abstract

A fluid applicator apparatus having a container, an applicator cap, a mechanism for allowing a pre-determined volume of fluid to be pumped from the container into a pad on the applicator cap and a protective overcap. The pumping mechanism has an attached ball-check valve arrangement which allows fluid transfer from either an upright or an essentially inverted position.

Description

Fluid applicator apparatus

The present invention relates to manual self-contained fluid applicator, particularly a kind of need pressurization, one-handed performance, from either direction fluid is applied at a certain lip-deep fluid applicator.

As prior art, existing people delivered a variety of self-contained, the fluid applicators that do not need auxiliary equipment.Two kinds of examples far from it can be described as pressurized jet aerosol container and dressing set composite hand-manipulated.The latter has two types basically: a kind of is the device that it must be turned around certain valve mechanism so that fluid charging is flowed through under the gravity effect, and another kind is upright or draw near the dipping tube that uses under the erectility and to send the formula device.

3,147, No. 512 United States Patent (USP)s " shoe polish injecting and applying machine " of Gleason are an example in the band valve gravity injecting and applying machine.

Manual operations is drawn and sent the container type set composite is on record, in this device, by dipping tube liquid is upwards drawn from a container bottom and to send, and makes liquid make atomized spray by nozzle again.This set composite is most widely used aspect lotion, perfume, cleaning agent or herbicide.

4,652,163 United States Patent (USP)s such as grade of Karliner etc. " fluid applicator and the using method thereof of band scraping " disclose a kind of gravity current dynamic formula applicator.This applicator has liquid container, a demountable scraping outer cover and independent protective cover of a band coating tool.When having circulation between the coating tool of a Sponge on container and outer surface, liquid is contained in nozzle in the container and the sub-assembly of spring valve is controlled by one.The spring that is contained on the container makes nozzle abut against the container neck inner face.Add a power when coating tool, be located immediately at nozzle below the coating tool cushion block and pushed away and in the indentation container, the path between nozzle and the container neck opening is opened, thereby liquid is outwards flow on the coating tool.

3,192, No. 553 United States Patent (USP)s of schwartzman " applicator of dribbling valve head " disclose a kind of liquid coating device, and this applicator has a container, a foamed material coating tool and a ball valve feeding machanism.This applicator mainly in order to coating shoe polish, has a cone-shaped opening at its container top.A spheroid that leans against on the bearing that is supported by helical spring leans in above-mentioned opening.Head on during the spheroid pressurized in the spring indentation vessel port, liquid is flow in the foamed material that covers on the vessel port air ball valve member around spheroid in container.Obviously, only when applicator is inverted liquid could under the gravity effect, flow out the ball valve of opening.

4,091, No. 966 United States Patent (USP)s of Laawe " the upright and dual-purpose squash type powder container of inversion " disclose a kind of flexible container, and powder sprays from container during squeeze receptacle, and powder is introduced into and is contained in the U-shaped pipe that is communicated with feed orifice in the container.The bottom of U-shaped pipe has an opening, has a feeding machanism on a top of U-shaped pipe, when container is upright powder from then on opening enter this pipe, powder enters this pipe from above-mentioned feeding machanism when container is inverted.

The problem of the existing dressing set composite hand-manipulated that need not pressurize is that the user mode of above-mentioned two kinds of main type applicators is opposite each other and mutual exclusive.Gravity feed can not use under erectility, and under inversion state traditional dipping tube and manually draw and send mechanism with regard to inoperative (because often making the dipping tube end expose liquid level after being inverted).Like this, on the dressing method He on the dressing direction limitation is being arranged all when applying fluid on a certain surface, the user must steering operation.Therefore, make manual fluid applicator can but also can under inversion state, carry out not only fluid dressing operation under erectility, just make various differences towards the surface on coating fluid much easy to operate.In addition, this set composite must be equipped with certain fluid metering mechanism, and this draws the formula device of sending to all is intrinsic characteristics, but does not then have this mechanism at most of gravity apparatus.

In coating when suppressing the fluid of insect, a kind of can difference towards the surface on the device of coating one whole piece desinsection or insect protected solvent then more favourable.

To be used for the method that the pesticides of cockroach, ant or other insects uses in a certain zone has integrated simply: fumigation, and this method is dispersed in pesticide in the whole zone, often needs food is taken out of this zone; Selection area is applied the method for desinsection foaming agent, and this method is effective especially concerning crack and slit, can stay unnecessary vestige but foaming agent is coated on the surface of exposing; The method of insect-catching device is set in a certain zone, as the bait release position is set.

The pressurizing vessel that applies pesticide is usually in order to suppressing the breeding of insect, but requires sometimes the input of pesticide is controlled accurately, makes its unlikely drift elsewhere.

But, adopt in all disinsection methods of pesticide at these, not having a kind of method or install can be to a certain selection area, no matter be the bottom of bin or the downside of shelf, directly the position is smeared liquid pesticide and made directly contact insecticide of user on request.A kind of method like this or matching requirements use a kind of coating tool that fuses with container, require to make the user just can carry out manual dressing operation with a hand.It is invisible that a kind of like this method or device also require the user in the zone of estimating the insect process these defence lines, several roads " defence line " to be set most effectively, but can remain valid in quite over a long time, and this depends on used insecticide formulation.

There has been a kind of like this method and apparatus that the bait point of isolation just needn't be set in a certain zone again, but, clearly, the zone that this can not be used for child or domestic animal might eat by mistake or mistake is licked.

Therefore, the purpose of this invention is to provide a kind of self-contained fluid applicator hand-manipulated, can enter to draw and send mechanism as long as in container, leave enough fluids, just can any towards the surface on apply quantitative fluid.

Another object of the present invention provides a kind of method that is applicable to the applicator of pesticide and uses this applicator, in order to suppress the insect breeding or to prevent that insect from entering a certain zone.

Fig. 8 is the top view of applicator cover outer surface embodiment illustrated in fig. 1;

Fig. 9 is the decomposition sectional detail drawing of applicator cover, cushion block and segment fluid flow conveying mechanism on the 3-3 section among Fig. 2.

In the embodiment of each recommendation, among each figure identical parts is adopted equal reference numbers.

Fig. 1 and Fig. 2 are the part exploded view of 10 two possible embodiment of fluid applicator, and both functions are identical, but the end face 20 of its applicator cover 30 is different with the direction of porous material cushion block 40.Also be shown with fluid container 50, protection outer cover 54 on Fig. 1 and 2, be contained in the closing cover 60 on fluid container 50 necks 52 and this outlet of the fluid issuing 70(that exposes be the part of fluid delivery mechanism 80 from closing cover 60, this fluid delivery mechanism is not shown on Fig. 1 and Fig. 2).

As shown in Figure 3, fluid delivery mechanism 80 comprises pumping mechanism 82, ball check valve 84 and the dipping tube 86 that extends to fluid container 50 bottoms from the bottom of pumping mechanism and ball check valve, the bottom of dipping tube is a fluid intake 87, fluid issuing 70 is positioned at the top of pumping mechanism 82, and passes closing cover 60.When making applicator, fluid delivery mechanism can setting-in be gone into the neck of fluid container, cause to reload fluid, but this can reduce the possibility of contacting with fluid as far as possible, thereby make this applicator increase protection feature to children.Also can make the neck 52 of fluid container 50 have the threaded portion that engages with closing cover 60, this just can open applicator and reload fluid.Most preferred embodiment about ball check valve 84 sees Fig. 6 and 7 for details.

Figure 3 shows that the fluid applicator that is under the erectility, applicator just can apply rectangular pesticide to the downside of bin etc. in this state, at this moment fluid 90(is housed in the applicator only illustrates on Fig. 6 and Fig. 7).When applicator being pushed to a certain surface, pressure just acts on porous material cushion block 40 and the applicator cover 30.When applicator cover 30 when the sliding area 92 of fluid container 50 main part longshore current body containers 50 slides backward, this pressure forces applicator cover 30 and fluid container 50 to be pressed against each other.

Pressuring action and pump action (below will give elaboration) are shown in the Figure 4 and 5, and applicator is in inversion state substantially among the figure, under this state applicator along ground, the lower surface or the similar surfaces of bin inside apply rectangular pesticide.As shown in Figure 4, the fluid container 50 of applicator and cover 30 are that sliding area 92(along liquid container 50 sees Fig. 5) be pressed against each other.As mentioned above, this state forces fluid to enter in the porous material cushion block 40 from pumping mechanism 82.As shown in Figure 5, fluid container 50 and applicator cover 30 are to be in extended configuration, under this state, the fluid of predetermined volumes are sucked in the pumping mechanisms 82 by fluid intake 100.Obviously, be used for before using applicator, being removed at carrying protection applicator and the outer cover 54 that prevents fluid delivery mechanism 80 random operations.

Fig. 6 and 7 is the detail drawing of pumping mechanism and ball check valve, and wherein dipping tube 86 is by brachymemma.Have a variety of pumpings and dipping tube sub-assembly available in the present invention, comparatively ideal is 4,230, and the pumping mechanism that No. 242 United States Patent (USP)s are announced proposes for your guidance at this.Provide the pumping mechanism of unique " arbitrary orientation " this feature and ball check valve joint institution to be published in 305, No. 288 United States Patent (USP)s.When applicator cover 30 is pressed on the main body of fluid container 50 (seeing Figure 4 and 5), fluid issuing 70 pressurizeds enter pumping mechanism 82, and compression biasing spring 94.Applicator is mentioned from the surface slightly, and behind the pressure on the elimination applicator cover 30, spring 94 promptly unclamps, and this just reduces the pressure in the pumping mechanism Room 96 82, so pass through dipping tube 86 with in fluid 90 suction chambers 96.When applicator cover 30 was exerted pressure once more, indoor fluid was forced out by fluid issuing 70 and enters in the porous material cushion block 40.

When applicator was in erectility, as shown in Figure 6, the liquid transporting body operation was as follows: ball 98 is positioned on the first fluid inlet 100 blocks it, and fluid 90 can only be sucked in the pumping mechanism 82 by dipping tube 86 ends second fluid intake 87.

When deposited applicator was in the inversion heeling condition substantially as shown in Figure 7, the fluid delivery mechanism operation was as follows: when applicator overturn, ball 98 rolled along path 10 2, thereby opened first fluid inlet 100.In this state, when pumping mechanism 82 moved as mentioned above, fluid promptly is sucked into by first fluid inlet 100 entered the room in 96.In this state, second fluid intake 87 generally all is positioned at the top of fluid 90 liquid levels.

Two kinds of possible fluid intakes are arranged, an inlet (87) is positioned near the fluid container bottom, another inlet (100) is positioned near the fluid container top, where fluid can be in office be subjected to drawing under the state of position and send, unique restriction is that applicator remains under the flat oblique angle, does not have enough fluids to cover the situation of fluid intake 87 again.In this case, the user only need make flat oblique angle become more steep angle, just the fluid of remainder can be drawn and see off.

Fig. 8 and 9 is depicted as the structure and the assembling details of applicator cover 30 and porous material cushion block 40.As shown in Figure 8, applicator cover 30 has and is positioned at end face 20 be used to pack into the groove 106 of porous material cushion block 40, centre bore 102 ' and from centre bore 102 ' outward extending groove 104.Fluid issuing 70 is fitted in the bonding part 108, forms a sealed engagement.As shown in Figure 9, in the applicator after assembling, fluid issuing 70 just in time be positioned at have hole 102 on the applicator cover surface 20 ' part following and contact with it.The porous material cushion block be positioned at groove 106 endoporus 102 ' and groove 104 above.When fluid delivery mechanism 80 moved as mentioned above, fluid was discharged from fluid issuing 70, then through via hole 102 ', so groove 104 will be from the hole 102 ' fluid of discharging spreads out along porous material cushion block 40 bottom surfaces.

The present invention also can adopt the diffusion mechanism of other types.For example with fluid applicator with the purificant fluid application on fabric or on the irregular surface time, brush type coating tool may be more quite a lot of than porous material cushion block.

After above-mentioned patent description and accompanying drawing are studied, be familiar with these professional personnel and obviously can make other change fluid applicator of the present invention.Therefore, some other change of the present invention is not although do special argumentation in the above, still in following claim scope.
