Description

SPRAY BOTTLE GRIP

The present invention relates to a manually operable device purposely designed to co-operate with a conventionally actuated dispenser discharging media, which by increasing the pression surface, enhances the force transmission and improves its pushing performance, thus ensuring the completeness of the pump actuating function and the delivered dose. More particularly, the operable device of the invention is advantageously co-operating with the adapter of a conventional dispenser spraying or, when necessary, discharging in larger droplets a fluid or a powder substance, more preferably a media containing one or more hygienic, cosmetic, pharmaceutical or medicinal active ingredients to be delivered either externally or into cavities of a mammalian body. The operating device is further intended to be easily manipulable, freely carried and/or single-handedly by old aged users or by persons with reduced manual capacity, in order to significantly increase the force transmission, but by applying the same manual pressure to a conventionally actuated pump of a dispenser discharging media. TECHNICAL FIELD OF APPLICATION AMD PRIOR ART While there are numerous dispensers discharging media in the art, no separate and manually operable device was found to conveniently increase the force transmission and the pushing performance of a conventionally actuated pump system of a media dispenser. A short history of the most significant media dispensing systems is summarized hereby not only for record purposes only, but also with the main purpose to better evidence and illustrate the unexpected functions and advantages of the manually operable device of the invention. Pioneering attempts for spraying medicinal products started on the beginning of last century. The objective was to apply "the medicine in the form of spray or fog to the surface of the diseased parts " (U.S. Pat. 780,077 "Medical Vaporizer" of 17 Jan. 1995 to Van Ness et al.). Thereafter an "Inhaler" to provide "a device of this class in connection with which medicinal or other substances are used as an inhaling agent, such, for example, as germicides, inhaling salts, or the like, which may be fluid or a composition of fluid and solids " in the form of tube and of a nasal applicator has been described in U.S. Pat. 2,064,314 issued to Morin.

A "Controllable Charging Head" appeared by mid of the last century with a "bottle, herein pressure-charge-carrying metal container adapted to receive and dispense pressure gas, say for dispensing at soda functions or like occasions in connection with foodstuffs or beverages " (U.S. Pat. 2,328,863 issued to Thream).

The most similar prototype of the current vertically extending cylindrical pumps is the "Pump Unit for Spray or Jet Devices" of the U.S. Pat. 2,362,081 issued to Martin et al. on November 7, 1944, where also the use of well suited thermo-plastics is recommended, "in view of the current shortage of metallic materials". The "Jetting Device" of U.S. Pat. 2,434,875 issued to Turnbull et al., which was designed "for projecting a needle-like jet of liquid in a direction axially to the device ", was "described particularly with reference to its use in a nasal medicator for introducing metered quantities of a liquid medicament into the upper part of the nasal cavities", such as the "sulfas, penicillin, vasoconstrictors or other drugs which should be used in limited doses ". Another inventive step introduced by Turnbull at al. is the "applicator head " having a rounded end fitting the entrance to the nostril, said head also having an axially directed orifice, and also a peripheral groove spaced axially from said end and constituting "finger-engaging means ". Samnels et al. (U.S. Pat. 2,906,265) introduced a "Nasal Adaptor for Valved Dispenser" for use in conjunction with a pressured valved dispenser. This nasal adaptor is presenting a base portion to provide a finger grip, while an "Aerosol Valve" was described in U.S. Pat. 3,155,290 issued to Verns et al. "for pressured aerosol packages in which a liquid product is confined within a container with gaseous propellant underpressure ". During the subsequent years an increasing number of "dispensers of the reciprocating piston type for discharging liquids from portable containers in the form of a fine spray or mist, or as a stream" (Corsette et al. U.S. Pat. 3,179,306; Thompson et al. U.S. Pat. 3,263,871 ; Stearns U.S. Pat. 3,591 ,059) or of "different applicators or devices" (Hall et al. U.S. Pat. 3,170,462 for ophthalmic use; Green U.S. Pat. 3,311 ,274; Clapp et al. U.S. Pat. 3,437,246) or of "aerosol valves " for aerosol substances in dispensing containers with propellants (O'Donnel et al. U.S. Pat. 3,225,969) were continuously presented.

Similarly, there was an increasing demand and use of pressured dispensing systems, based on fluorocarbon propellants. Fluorocarbons were widely used over more than fifty years as inert suspending vehicles for many substances and simultaneously as propellants for aerosol spraying systems. In fact, fluorocarbons present the property to be liquid at room temperature (when packed under adequate pressure in a sealed can or container) and to be instantaneously converted into a volatile gas vehicle, when the liquid is released at normal pressure conditions through a pressure valve operated with a push button. Only by the end of the eighties scientists started to report that these fluorocarbons were exerting a tremendous negative ecological impact on the atmosphere, as the possible origin of ozone holes. Consequently their use has been drastically restricted and even banned in favour of conventional pump systems, which do not require such pressured fluorocarbon propellants. In view of the above, the demand of reciprocating pump discharge systems for a liquid or a powder media has been sharply increasing in many fields, as for instance for hygienic, cosmetic, pharmaceutical and medicinal applications.

Therefore, over the past decade the technicians have been multiplying their efforts either to improve the known pump systems and to optimize some components (as for instance, pumps, applicators, protection cases and other parts) or to invent new technically advanced dispensers discharging media. More recently, sophisticated models of media dispensers have been also suggested by some inventors, alike the folding actuator of U.S. Pat. 6,173,868 to DeJorge, the spray apparatus of U.S. Pat. 6,302,101 to Py, the dispenser of U.S. Pat. 6,446,839 to Ritsche, the discharge apparatus with lateral pusher described in U.S. Pat. 6,454,185 to Fuchs and in U.S. Pat. 6,527,144 to Ritsche et al.. In fact, some recent dispensers for spraying media are presenting new designs, but limited technical advantages over the prior art. Additionally their major disadvantage for a large scale use remains an unaffordable cost per unit, particularly when these new discharge systems are monodose and disposable.

Another disadvantage of these sophisticated dispensers is that their automatic industrial production and media filling operations require remarkably significant investments in terms of specific and sophisticated assembling machinery. Therefore the disadvantage of their intrinsic and extrinsic costs are remarkably limiting their widespread application. Therefore today the best attention is still paid to the use in many fields and for large scale applications of conventionally operable dispensers spraying or, when necessary, discharging in larger droplets a liquid or a powder media, as already described in the known prior art. Such dispensers are typically constructed in such a general way to have an affordable industrial cost, to cover a wide range of potential applications and to contain the following essential separate components :

(1 ) an open end single or multidosing container, generally a bottle from a small cylindrical size from rigid material, having a minimum package or storage volume;

(2) a manually operable pump component, preferably a metering pump, associated with a screw cap or with an aluminium crimp-on cap to be secured to the open end of a container, which includes a pump stem reciprocating with the discharge channel of an applicator or alike; (3) actuator, adapter, push-nipple or casing, having an actuating head exially to the centre of an upper support body with a discharging channel precisely reciprocating with the pump stem and a spraying nozzle or outlet media at the opposite. The channel is receiving, transferring and spraying the media on the desired surface or into nostrils, hears, mouth and other orifices. This part presents also a sort of finger-engaging mean, platform or a push element, with a gripping surface, flange or shoulder for pressing with the thumb, fore-finger or medius of the user; (4) dust cover for the actuator described at the point (3) with or without a nozzle orifice closure.

The dispenser may be preferably multidose and the actuator may be conventional or with a progressive dose indicator. The variety of available embodiments of said conventionally operable dispensers seems to have apparently fulfilled the current demand both in terms of needs for the different fields and applications and also of affordable industrial production costs, but these conventional dispensers, alike the sophisticated discharging systems, present a reduced pushing performance so that this problem still remains unsolved or without adequate solution. Indeed these force transmission problems to the actuating pump are objective and subjective, as clearly resulting from the observations reported from several users, which are listed here below. More particularly in the pharmaceutical and medicinal fields one of the actual problems of the current conventional dispensers is represented from the small dimensions of the container, mainly bottle, which remarkably originates handling, in-use and dosing problems to the patient, as a consequence of an increased difficulty of a normal user to manually perform the required pushing operations. Additionally, in most of the cases the above problem is even worsen when a person of advanced age and with reduced manual capacities operates the small discharge apparatus, with the possible risk of a scarce force transmission, of a partial pushing performance and of incompleteness of the dispensed dose of the media containing the pharmaceutical and medicinal product. In fact the objective and subjective actual problems of a partial, insufficient or inadequate pushing performance may be the result of some concomitant negative factors, alike :

(a) the standardization of the production process requires an uniformity of shape and size of the actuator of a conventional dispenser. A cylindrical base body (with an axially central head) and annular size not exceeding the outer circumference of the bottle are compulsorily required, but the above standardization leads to different problems ;

(b) another objective problem, in the case of pharmaceutical and medicinal products, wherein often the adapter has to be introduced into an orifice, is that a too large diameter of the applicator may cause a difficult approach of the dispenser to the selected orifice ;

(c) due to the limited annular size and shape of the base body of the adapter and that the adapter head is occupying a large portion of the upper circumference of the adapter, the actual residual gripping area on each side of the head of the applicator is resulting extremely limited and in main cases the length of the gripping area on each side does not exceed 6-8 mm. This is insufficient for hanging the fore-finger and the medius of the user to exert the required mechanical force on the actuator, considering that adult fingers width usually vary from 15 to 22 mm.

Under these conditions, often the manual force on the pushing area of the actuator is insufficient to transmit the necessary pressure to the metering pump to secure not only the completeness of the programmed dose/volume of media, but also the correct destination of the discharged media on the selected area or body;

(d) the subjective problem is that the dispensers are often manually operated by old aged users, sometimes with considerably reduced manual capacity, thus leading to the appreciable risk of a reduced force transmission with partial pushing performance and of incompleteness of the dispensed dose of the media containing the pharmaceutical and medicinal product to be administered. Therefore there was a real need in the art of a manually operable device purposely designed to co-operate with a conventional dispenser discharging media to enhance and to improve its force transmission and pushing performance, thus to ensure the completeness of the pushing operation and of the delivered dose of an hygienic, cosmetic, pharmaceutical or medicinal active ingredients to be administered either externally or into cavities of a mammalian body. OBJECT OF THE INVENTION It is an object of the present invention to provide a manually operable device purposely designed in such a way that it advantageously cooperates with any conventional dispenser discharging media, to enhance the force transmission and to improve the pushing performance of said dispenser and to ensure the completeness of each actuation of the delivered dose of media.

Particular preference is given to a manually operable device to facilitate the manual pushing operations and to increase the pushing performance of a dispenser discharging media to be used by persons of advanced age or with reduced manual capacity.

It is also advantageous that the operable device of the invention cooperates with a discharge dispenser spraying, atomizing or, when necessary, discharging in larger droplets a fluid or a powder media, said media containing one or more hygienic, cosmetic, pharmaceutical or medicinal active ingredients to de delivered in a precisely defined dose either externally or into cavities of a mammalian body. It is particularly advantageous that the manually operable device of the invention is easily manipulable, freely carried and/or actuated single- handily and a long-term usable element, which may easily adapted to several types of conventional dispenser discharging media.

A further advantageous embodiment is that the manually operable device of the invention is a separate element which may be easily installed by a normal person on the head of the actuator of a conventional dispenser discharging media before its use and also removed, if necessary, to be either disposed or reinstalled in another dispenser.

It is a very advantageous embodiment when the manually operable device of the invention is combined with a conventional dispenser for discharging media to obtain a better force transmission and pushing performance, with a remarkably lower cost than the most modem and sophisticated discharge systems.

These and further features of the invention will become apparent as the description thereof proceeds and can be gathered from the claims, description and drawings and the individual features, either singly or in the form of sub-combinations, can be implemented in an embodiment of the invention and in other fields and can represent advantageous, independently protectable constructions for which protection is hereby claimed. The subdivision of the application into individual sections and the subtitles in no way restricts the general validity of the statements made hereunder.

SO RSEflARY OF THE 1MWEWTDOM

More particularly, the manually operable device of the invention is characterized to advantageously operate in order to remarkably enhance the operating force and the pushing performance of a reduced pressing area or of any other part with insufficient pressing functions of a conventionally actuated dispenser discharging media.

In fact, the manually operable device of the invention is also characterized to develop a transmission force to actuate the pump of a dispenser in accordance to the know equation : (F) = (P) x (S) wherein : (F) = transmission force ; (P) = pressure ; (S) = surface However, the transmission force (F) necessary to actuate a pump of a dispenser is directly proportional to the result obtained by multiplying the pressure (P) by the surface (S). As a result of the above, the same or an higher value of transmission force (F) may be simply obtained by increasing the surface (S), so that the simultaneous operating pressure (P) may be the same or even reduced, as in the case of old aged users or of persons with reduced manual capacity.

Using the same equation it is possible to foresee the reulting transmission force (F) to activate a pump, only varying the available surface factor (S) of the operable device of the invention. The operating device of the invention is further characterized to be a separate element from the dispenser discharging media, as shown in the drawings. For description purposes only the operating device has been divided in three portions, as described hereafter :

(A) upper collar

(B) connecting body

(C) annular ring or convex surface being only portion (A) upper collar the essential portion, while the other optional portions (B) connecting body and (C) annular ring or surface may not be present in all embodiments of the instant invention (FIG. 1a to 1d). Obviously, the exclusion of portion (B) automatically excludes also the last portion (C).

The essential portion (A) upper collar (FIG. 2a to 2h) may be used alone as a separate portion or in connection with the optional portions (B) connecting body (FIG. 3a to 3f) and (C) annular ring or surface (FIG. 4a to 4c) and all of them are composed mostly or completely of injection- molded or rigid or semi-rigid plastics. The upper collar (A) shape is generally oval or oblong (FIG. 2a to 2f), but without any design limitations and with the possibility of many possible embodiments, and presents preferably a centric hole (1), which may have different size and shape depending on the annular circumference with the shoulder of the adapter head.

The function of the hole is to conveniently insert the upper collar (A) into the adapter head in such a fashion that the lower surface of the collar (2) reciprocates with the actual upper annular disk of the base body of the applicator. The upper collar (A) is further characterized that its shorter part between two opposite elliptic pints shall not be protruding more than 15 % beyond the outer circumference of the base body of the applicator, but in any case the shorter part shall not exceed 4 cm, while the ratio between the longer and the shorter parts of the ellipse shall not be more than 4, but in any case the longer part shall not exceed 8 cm.

The upper collar (A) is further characterized that the centric hole (1) has the same annular circumference (some microns tolerance are allowed) as the base of the adapter head, so that the collar can be conveniently inserted into the head, but without excessive allowance, in order to completely adhere to the upper surface of the body of the actuator. In another preferred embodiment the upper collar (A) presents a lateral slot (3) (FIG. 2g & 2h) , connecting the centric hole with the external part of the collar. The slot on the oval collar shall have the same size as the diameter of the centric hole, so that the adapter head can be inserted into the central hole of the collar simply by lateral migration through the slot.

More preferably, in another embodiment the adapter head presents on its base a suitable groove (scanalatura) precisely reciprocating with the slot of the hole of the collar, in order to better secure the connection between the two elements.

It is further preferred that, when portion (B) is present, said slot on the collar shall be obtained on the more narrow side of the oval. The material thickness of (A) and of the other portions (B) and (C) may vary considerably, according to the characteristics of the used injection- molding materials and plastics and of the specific factors of the discharge dispenser to be connected with and in relation to the required pushing performances of the operating device of the invention. Therefore the thickness shall vary from time to time, according to the above different factors. Regardless that the shape of the portion (A) is without any design limitations, further embodiments are mentioned hereby for reference only, alike gripping patterns on the upper surface, anatomic wings (FIG. 2e & 2f) or hanger systems. In another preferred embodiment the lower surface (2) of the (A) is further characterized that it is conveniently provided with any kind of ready-to-use adhesive material, like adhesive tape or pad, as it may be available on the market, in order to firmly stick the lower surface of the collar after it has been introduced around the adapter head and it has been overimposed to the upper annular body of the dispenser adapter. The optional portion (B) connecting body, when present, is shaped as one-part body (FIG. 3a & 3b) or as centrally divided two guided travelling projections (FIG. 3c). At one of the reciprocating ends (4) a slidingly guided projection is centering the guided projection (5) of the opposite end. Optionally an axial stop system with a member or with a screw stop may be installed in one of the travelling portions, in order to adjust the desired distance of (B). The one-part body is consisting of a convex shaped surface (FIG. 3d & 3f) of two or more parallel plastic bands (FIG. 3e & 3f) placed at a suitable distance from each other. The plain plastic surface sheet (FIG. 3d) is preferred for (B), when (C) is not present. While the height of (B) shall be conveniently predetermined or adjusted in presence of (C), since this is in relation to the size of the used dispenser discharging media to co-operate with, a different height may be used in absence of (C).

In a further embodiment, being absent (C), when (B) is made from plastics, it is preferable that the length of the developed surface (FIG. 3d) may conveniently cover from 3 % to 100 %, more preferably from 30 % to 65 %, of its annular circumference.

In another embodiment, when two or more parallel bands of (B) are used (FIG. 3e), it is almost compulsory to suitably injection-mold together the parallel bands to (C) portion. The characteristics (position, surface, type) of the connecting junction edges between the portions and the thickness of these plastics portions may vary considerably, according to the characteristics of the used plastics and of other specific factors alike the discharge apparatus to be connected with and to the required pushing performances of the operating device.

Preferably, the position of the junction edge between (A) and (B) is corresponding to the portion of the oval perimeter presenting the shorter diameter, while there is no preference of portion for the junction edge connecting (C).

In another embodiment the optional portion (C), when present, is further characterized to be an annular ring (FIG. 4a & 4b) made from rigid or semi-flexible injection-molded plastics suitably connected with portion (B). The annular ring or surface is constructed in such a way that when the upper collar (A) is suitably installed on the adapter head, the ring is surrounding the cylindrical body of the bottle, in order to better secure the bottle to the operating device of the invention. In another embodiment (C) is further characterized to be a plain annular injection- molded surface (FIG. 4a & 4c) and it is preferable that this surface cooperates with the bottom of the bottle of the dispenser. For operating the device of the invention, the user must introduce a force (F) acting in the direction of the arrow (FIG. 6b) by means of the upper surface of the device onto the actuating element of the dispenser discharging media. The transmission force (F) is that necessary to operate the adopted actuating pump and is specific of that pump. Therefore, according to the already mentioned equation : (F) = (P) x (S), if the operating surface of the dispenser is reduced or sufficient to hang only part of the used fingers (mainly fore-finger and medius), the operating force to suitably actuate the pump can be obtained by proportionally increasing the pressure, in other words by exerting a much bigger pressure. This performance which is required to the particular users of the dispensers, who often are old aged patients with serious problems of manuality is difficult. Therefore the manually operable device is further characterized to considerably increase the handling surface and with the same pressure considerably increases the operating and transmission force to the pump system and thus the pushing performance of the actuating element of a conventional dispenser discharging media. The discharge stroke produced with the use of the operating device definitely ensures the completeness of each actuation of the delivered dose of media, particularly when the user is a person of advanced age and/or with reduced manual capacity.

The manually operable device is further characterized to be easily manipulable, freely carried, actuated single-handedly by conveniently using the fore-finger and the medius, which are actuating on the suitable larger surface of the device, thus exerting an adequate force transmission to the actuating pump of the dispenser. FIG. 6c shows a perspective view of how to conveniently use the operating device of the invention.

The operating device is further characterized to be a separate element from the dispenser discharging media, so that the same is also a long- term usable element, which can be easily removed and reinstalled in the same dispenser or adapted to several types of conventional dispensers. Similarly, the installation of the manually operable device is very easy and the operation can be done by any person, even old users. When the manually operable device is complete of portions (A), (B) and (C), the conventional dispenser is introduced laterally in the up-right position, in order that the head of the adapter enters completely into the centric hole (1) of the upper collar (A) which shall adhere and reciprocate completely with the upper annular disk of the base body of the applicator. When only portion (A) is used, the head of the adapter of the conventional dispenser is introduced into the centric hole (1) until the lower surface of the collar (A) fully adhere and reciprocates with the upper annular disk of the base body of the applicator. FIG. 6d shows a perspective view of how to conveniently use the operating device of the invention (A) on a conventional dispenser. When the lower surface of portion (A) is conveniently provided with any kind of adhesive tape or pad, the protective film of the adhesive material shall be conveniently removed before the installation so that it may suitably adhere to the upper surface of the base body of the adapter.
