"Automatic dispenser for intermittent delivery of an aerosol."

The market for goods in aerosol packaging has enjoyed an excellent y / axis turn and benefit since 195o. However Recent consumer research has shown a growing increase in negative attitudes towards aerosols in general shown. In particular, the consumer is concerned about

a) the increased cost of aerosols with decreasing "apparent value",

b) poor functioning of the product including valve clogging and / or failure to distribute all of the content and

c) Overpacking, i.e. the aerosol form does not contribute to the product presentation rather, it is viewed as an expensive "convenience".

B09823 / 0723.

ORIGINAL INSPECTED

As a result, it is not surprising that cuuj is growing at certain aerosol groups such as air fresheners and pest control begins to decrease. In particular, the ^ vulnerability of these groups to The introduction of aerosol-free products is noteworthy. Examples include pest control strips and solid air fresheners a. Consumer research has shown that the success of both of these aerosol-free products is primarily based on Reason for the need for the consumer for a steady or ongoing performance as opposed to dwindling Aerosol atomizer performance !! was present. It it is understandable that many pest control and odor problems are lengthy in nature and require steady treatment. Such treatment can be annoying and be time consuming. The various solid products were trained to meet the need for the consumer for a continuous long-term application; correspond to. These solid products have and are performance limitations generally a performance compromise when it comes to the volatilization properties of the carrier material and the distributed active materials are limited.

While a large number of intermittent, maintenance-free or automatic xi aex'osol dispensers opposing xanu of patents is, not a single device is known as the one

609823/0723

using expensive electrical clocks that had an economic success. One major problem has been the cost; however, there are multiple problems with delivering very precise amounts of aerosol worn product available. On the one hand i ;; i, it with conventional ytrümungsatcuerelnrichtungen such as Needle valves difficult to achieve an adjustment tip sensitivity, which is required to dispense extremely small amounts of product. It is also difficult to get an earlier hiring reproduce when the plunger of the load valve is moved. Another problem is with unsubscribing in fairly constant Intervals between dispensing, especially if the interval is measured in days or hours and the whole Operating time can be a few weeks or months. Another problem is to create a lively output, that is free of any initial or residual dripping of the liquid Product is under low pressure causing stains next to the dispenser or in the very small dispensing passage can dry out and inhibit further operation.

Also because of the wide range of products and propellants and because of their properties in the problem, a maintenance-free one To produce aerosol dispensers that meet the requirements for a large number of products and propellants, has not yet been resolved. For example, the

609823

Components of some aerosols in a single liquid Phase in the container, i.e. a substantially homogeneous one Mixture. The components of other aerosol products are in double fluid phase, i.e. permanent propellant is separate from the product and collects in the upper area the container in a gaseous phase, and the product collects at the bottom of the container in a liquid gen phase for the purpose of exiting through a dip tube. At Aeroso Oils that are present in a single phase can, at a certain release stage, have a gaseous phase at the tip of the container due to the pressure drop.

The present invention eliminates the drawbacks of more known ones intermittent or maintenance-free aerosol dispenser and can be summarized as follows.

One object of the invention is a reliable, simple one Maintenance-free aerosol distributor to be operated at low cost, the one with adjustable or pre-selected extended ones Intermittent intervals between dispensing.

Another object of the invention is an intermittent Aerosol dispenser 'which, when activated, is a

lively or sharp delivery pattern of short duration, i.e. although the operating period is short, the discharge profile includes an initial gas component delivery which principally, if entirely, is composed of the propellant is, according to which a liquid component release, which is mainly composed of the product and finally a second gas component delivery follows, which also mainly when it does not consist entirely of the propellant.

Another object is the elimination of droplets or fibers of the liquid with the aid of the delivery profile according to the aforesaid subject, this being accomplished by using the initial gas discharge to volatilize any condensed liquid in the flow path and, by using the final gas discharge, to volatilize any residual liquid.

Another object of the invention is an intermittent Aerosol dispenser with a rearranged collector area in which during the accumulation period between the delivery of the aerosol, i.e. the combination of product and propellant, in sub-areas arranged one behind the other is collected for the purpose of successive Delivery in gas-liquid phase phases, as mentioned above is .

609823/0 7 23

Another object of the invention is an intermittent aerodynamic divider which has a newly arranged flow control body which has elongated labyrinth or tortuous passageways that cause the Product and propellant are subjected to a gradual pressure drop as it moves from the container to the header area flows, which results in at least a partial volatilization of the propellant, which is a liquid phase and forms a gaseous phase which flows into the collector area for subsequent release »

Another object of the invention is an intermittent aerosol dispenser with a tilt valve device which controls the delivery from the collector area.

Another subject matter is an intermittent aerosol dispenser, one embodiment of the flow control body in the form of a porous body with a plurality of randomly arranged passages vox 'while Another embodiment uses elongated, substantially uniform passages.

Another object of the invention is an intermittent aerosol dispenser with a newly arranged, γοη hand

60 9823/0723

operable device so that the time interval between departure can be adjusted.

Another object of the invention is an intermittent Aerosol divider, one embodiment being a new one includes means arranged so that the dispenser is manually operable without the subsequent automatic To disrupt operation.

Another object of the invention is maintenance-free (unattended) aerosol dispenser, which is a new device which is particularly suitable for dual phase aerosol, wherein all or part of the product and the Propellant separate from the receiving end of the dispenser supplied v / earth.

Reference is first made to FIGS. 1 to 5. The embodiment of the aerosol dispenser shown there is arranged such that one portion of the dispenser is permanently disposed on a container and the other portion is removable so that it can be used with a number of containers. In particular, an aerosol container 1 is provided which encloses an end cladding 2 with a sleeve 3 made of sheet metal material. The sleeve 3 is circular and contains a lower jacket 4 _} which is essentially cup-shaped with a cylindrical wall and receives a porous cylindrical flow control body 5. Under the flow control body 5 an inlet chamber 6 is formed which is connected to an inlet plunger 7 which in turn is connected to a dip tube ti which extends to the bottom of the container.

The sleeve 3 continues to take an upper jacket 9, the a downwardly open cylindrical Samral chamber 1o forms.

A retaining ring 25 is fitted over the diaphragm valve 23, which has a circumferential support 26, which with the scope det; Membranventilec opposite the support shelf 22 in engagement chair, screwed into the retaining ring 2 ^ is a filling screw or an actuator 27 with a central nozzle 2b in the i'orm of an outwardly diverging one Opening. The valve plate 43 and sealing washer 18 form a valve chamber 17 between them.

The term "actuator ¹¹ refers in the broadest sense to the device that is used to operate the tilting diaphragm valve. This is accomplished by initiating the flow of product from the container directly or indirectly to the tilting diaphragm valve, thereby actuating the latter. Thus, the. The actuator may be a screw such as an adjusting screw 27 in the embodiment shown, which actuates the diaphragm valve 23 when it is not screwed in, so that the actuator can move.

The collector chamber 1o, passages 12, 21 and 2o, the valve chamber 17 are connected to one another and form a collector area; The chambers 10 and 17 thus form collector sub-areas.

609823/0723

If the aerosol divider is not in operation, a wire cap (not shown) is arranged over the tubular plunger 12. V / mm the cap is removed some dispensing occurs, but the flow rate is limited by the flow control 5 so that a minimal amount is lost and that loss ceases when the valve housing 14 is positioned over the plunger, as in Pig . 2 is shown.

When the housing 14 is fitted on the plunger, the adjustment screw 27 is in its lower position, as in Pig. 3 is shown in which the tilt valve is held against the valve seat 19 so that dispensing is prevented. To put the dispenser into operation, the adjusting screw 27 is in the Pig. 2 position shown screwed. Initially, the pressure in the header area including chamber 10 and the underside of the tilt valve 23 is at atmospheric pressure.

As will be described in detail later, the flow control body Take 5 different forms. The body can be made of sintered metal or plastic material with open pores or formed from fibrous material, i.e. any material which has a plurality of labyrinth passages creates, the minimum length of which is corresponding,

to ensure that the product and the propellant are used through the flow control body at one speed which will determine the period between operations ranging from a few minutes or less to a few Hours or more can vary. The volume of the collector's hay is low, for example usually less than 1 c cm.

The pressure in the collector area slowly builds up under the diaphragm valve 23, which causes that moved the valve to a flat position, as in Pig. 4 is shown. During the movement, the valve disc 18 follows, which is made of an elastomeric material, the diaphragm valve, until the Mumbran extends beyond the center emotional; then the membrane tilts, supported by the pressure below, into the position shown in FIG. 5, so that the central perforation 24 is suddenly opened in order to dispense product and propellant through the nozzle 2i $.

It should be emphasized that by varying the volume of the collector area and the flow velocity in the following states are possible for the collector area:

1. Low volume delivery - frequent intervals.

2. Low volume delivery - not frequent intervals.

B0 9823/0 7-42-3

3 · High volume delivery - frequent intervals.

4. High volume delivery - not frequent intervals.

The gradual pressure reduction, when the product and propellant mixture flows through the porous S troniurtgssteuerkkörpers 5, results in a certain separation of the product and the propellant and also causes the propellant, if initially in the liquid state, at least partially converted into its gaseous state especially during the initial low pressure build-up. As a result, the liquid product collects in the lower portion of the collector area 1o, which covers the lower jinue of the protruding pipe 11, as in Ji ¹ Ig. 2 gezei ^ b int. The liquid also extends partially into the barrel 11.

If the valve suddenly moves out of its ini <'ig. 4 into its closed position shown in Ji ¹ ig. b moves, there is a brief and rapid initial release of pressurized, gaseous propellant, ei as has accumulated in the collector sub area 17 and any pre-deposit of liquid product volatilized. This initial discharge creates a pressure drop in the sub-area 1o, thereby causing the water deposited in the upper portion of the upper area 1o to occur.

609823/0723

gaseous propellants shot through the liquid drives the passages into the sub-area 17 and through the dispensing passage 24. V / emi the pressure drops, expands the liquid propellant remaining in the product and propels the product through the dune 2b, whereby finally the gaseous propellant, as originally the pipe 11 surrounds, is dispensed and drives any remaining product out of the nozzle 28. During such a delivery would be the Pressure under the diaphragm valve is reduced to a point that the diaphragm flips back to its normal position, like this in Pig. 2 is shown

Referring to Figure 13, there is shown a diagram that has an operating cycle of approximately 10 minutes including alternating a Samrnlej zone and one Shows delivery zone in which the valve opens at about 2.b1_kg / cm * ": and at about 1.41 kg / cm reseals, the Duuer of the delivery zone is less than 30 seconds.

ils it can be seen that once the Bruct. under the Diaphragm valve has reached a predetermined level, that is shown at 2.81 kg / cm, a sudden opening des / entiles a rapid pressure decrease in the collector area and an initial and final release

The adjustment screw or actuator 27 may be finely threaded so that the distance traversed by the diaphragm valve when it tips over center can be adjusted. For example, the diaphragm valve can be arranged no , that en at a

Membrane drop to 1.41 kg / cm before the membrane tilts back to its original position, shown by solid lines in 1 " ¹ Ig. 2. When the adjustment screw 27 is moved down to a point just below the point at which the membrane tends to tilt to the open position, the diaphragm valve can scnließen when the pressure of 2.81 to 2.57 ^k;; / drops cm It can be seen that when the diaphragm valve in its complete. Moved open position, the valve opening is maximum to allow maximum delivery of the friction agent and product, but to provide operation for a reasonable period of use, the maximum delivery represents a small volume of pressurized liquid. When the diaphragm valve If it is set for minimum movement, the dispensing will be much less, and even if it is set for maximum dispensing speed, the period between dispenses will be significantly lower

1.41 to 2.01 kg / cm increases while under the conditions a minimum delivery rate (tie period between levies is also at a minimum, as the pressure is only about 2, ίί7 on 2, over 1 kg / cm * "increased.

Referring to Ji'ig. 6 can, if desired, Instead of axially directing the contents of the container radially, the sealing washer 18 has a radial passage 29 with an entrance within the middle x-ing-shaped Be provided valve seat. The housing I4 is provided with a radial nozzle 3o, the central perforation 24 is omitted from the diaphragm valve, and it is a massive one Adjustment screw 31 is provided.

The construction according to i'ig. 1-6 allows the flow control body to be of smaller size since it only has to function during dispensing from a single container and the total flow therethrough is limited. The clock and flow control body need not be consumable, but can be used repeatedly on a number of aerosol containers. How, however, in! «Ig. 7, the entire dispenser can be arranged as a unit; so in 1 ' ¹ Xg. 7 (where

Above the lower jacket 4a is an upper one Shell 32 arranged, which combines the functions of the upper shell 9 and the valve housing 14, i.e. the lower portion of the upper shell 32 is downwardly open collector cam or sub-area 10a provided, which has a downwardly directed tube 11a. The upper portion of the upper shell 32 forms an upward Pointing recess, which is ok by the collector chamber a partition 34 is separated.

The recess above the partition wall 34 accommodates a sealing washer 18a and a diaphragm valve 23a, which with the disk 18a forms a valve chamber collector subregion 17a forms. A retaining ring 35 with a circumferential support frame 26a is provided over the upper end of the upper casing 33. The retaining ring 35 has an internal thread to an adjusting screw 36 with a x "nozzle hole 37 to accommodate.

The embodiment shown in FIG. 7 operates in the manner described for FIG. 2, but the time interval between operations is significantly increased by the presence of the cover disk 3b , only a small portion of the upper surface of the flow control body 5a being exposed.

The function of the flow control body and the cover disk is shown more clearly in FIG. The mutually facing surfaces of the porous body 5 a and the disc 3 may be ^ provided with a seal, except for the area of the body 5a, which is below the perforation 3 ¹ J. A soft seal (not shown) can be used above. As indicated with the aid of the arrows, the number of labyrinth passage outlets that are exposed to the perforation 39 is greater than the number of labyrinth passage outlets.

The sealing washer 73 functions in the same way like the sealing washer 1 ti, as during an initial movement of the valve member the sealing washer makes sealing contact maintains. The spring does not need to be over-centered because when the spring arms become one move the horizontal position, the force required to move the spring is less, so that a point is reached, in which a tilting action occurs causing the propellant and product to be dispensed, such as this is described above. Adjustment of screw ö7 determines at which reduced internal pressure the effect of the pressure is bridged by the springs, and the cycle repeats themselves.

Referring to Figs. 17 and 1b, this is the construction especially created to provide control of the time interval between dispenses. The distributor is for inclusion arranged in a sleeve 3e and comprises a cap-shaped Jacket 88 with cylindrical walls, the bottom being provided with an inlet tube 89.

Since the range of products and propellants for a maintenance-free intermittent dispensing

809823/0723

can and also the optimum dispensing and the period may vary significantly between your dispensing, the Great and porosity can and after the material from which the Ütrömungsuteuerii-dx ^ pex ¹ 5! b'ig. 2 or in other embodiments, vary significantly. However, there are certain properties that are essential for all exemplary embodiments, namely

1. For a given product, the collection ρ er i ο d e should be reproducible i.e., once a period of accumulation has been built up, e3 should be possible, a large amount by dispensers with no material variation in the collection period, so assuming a use of Containers of a given size the entire delivery period in will remain essentially constant.

2. While the volume released at the end of each jar period is determined by the size of the jar area, which can be different for different products, the volume of the jar area is necessarily small compared to the volume of the outer container, for example, but not restrictive 1 cm or less.

Jj ^{1 For} experimental purposes, a sintered metal flow control body with a maximum pore size of

609-823 / 0 * 2-3-

0.2 microns, 9 »525 mm in diameter and thickness of 3.175 mm. Since the thickness of 3 »175 mm 3.175 microns was the maximum length of a pore passage through the flow control body 15.875: 1 In fact, the average pore passage was longer than this ratio because each pore passage was tortuous was.

The outlet side of the flow control body was of a rubber seal except for an opening with a diameter sealed by 0.254 mm. The flow control body was used in an embodiment of the dispenser, which was essentially the same as that of Fig. 7 and connected to an aerosol container having a capacity of has approximately 300 g of product and! ' l''for trying the product was an air freshener known under the trademark "Lysol", and carbon was used as a friction agent luoride used. The container had an initial one

Pressure of approximately 5.27 kg / cm. The tilt valve went like this designed to open at a pressure of about 2.81 kg / cm and to open at about 1.40 kg / cm closes.

The dispenser gave the container quantities in approximately 30 days away. Dispensing takes place every 18 minutes with a deviation

609823/0723

of approximately 2 minutes. The average duration of the The delivery period including gas-liquid-gas phases was less than 1 second.

If the pore size was increased to 0.4 microns or the outlet increased to 1.4 mm, the rate of delivery would decrease increase by four times, i.e. the operating time would be 7 days

While the material chosen for the experiment is sintered Stainless steel, many other metals can be used as it is assuming a lack of a chemical or solvent reaction are the number and physical dimensions of the pores which determine the rate of delivery determine. Most ceramic materials and many plastic materials can also be used. different pasers made of paper, fabric or glass, if they are compatible with the propellant and the product.

In a further experiment, discs similar to those according to Pig. 27 used. These were arranged around a spiral Flow path of 2 m with. a hole of ο.15 mm χ o, o75 mm to form. This V / eg was applied by 144 g in 48 hours of 2.5 ^ g per hour. A second attempt was made performed, with a helical bore of the

609823/0723

the same length and cross-section was used as in the previous experiment, but it was veraohon with opposing stone pines, as in 1 ' ¹ Ig. 29 are approved. The weight was 62 g in 40 hours, oaei * 1.29 g per hour. A pressure of 4.92 'kii / aa with an iebunijöteraperatui · of 21.1 CJ was used in all experiments.

While the various embodiment forms can be operated in an upright position, ie with the dispenser at the upper end of the aerosol container, they can also be arranged in an inverted position for operation. In this case the initial release will be liquid that has settled at the bottom of the header area, followed by a final gas release due to the impingement of abrasive in a gaseous phase under the flow control body. The presence of the outward extension to Durciigang 11 causes little inclusion of positive phase component. \ Ίβΐηι, however, the alarm period is essential, a further change to the gaseous phase will occur. Such trapping can be avoided by omitting the initial stretching and by using a U-bend in the passage 11.

It should be noted that the term "aerosol" is used herein is to denote the product - propellant - mixture

809823/0723

of which components are present in the gaseous or in the liquid phase. Also, the terms "tortuous" and "labyrinth" are used interchangeably, that is, each term includes the passages in your porous body, as in 1 ' ¹ Ig. 1 to 25, 3o and 31 or the passages in the hatched stack according to 1.
