(77 Clark Ave, Staten Island 6, N.Y.)
Filed Jan. 29, 1954, Ser. No. 407,054 (Ilaims. ((31. 239318) This invention relates to the art of receptacles or containers adapted for the retention of fluids therein under substantial pressure conditions. More particularly it pertains to bottle type receptacles, illustratively of glass or analogous derivation, capable of withstanding substantial fluid pressures throughout the internal surface thereof and affording an enhanced resistance to breakage. In its preferred adaptations, the invention is predicated on a container of the aforesaid type adapted for coordination with a dispensing means or the like operable by the creation of a hydraulic pressure Within the container by passing a vehicle, such as water, under pressure through a main conduit, and effecting a by-pass or diverted flow of the vehicle into the container for expelling therefrom a chemical substance. In its essence, the invention is predicated on features of structural novelty directed to substantially obviating the breakage characteristics normally applicable to conventional bottles under similar conditions of use.
To facilitate an consideration of the invention, it will be considered hereinbelow with reference to a bottle container of vitreous derivation, preferably glass, although it will be understood that containers fabricated from other materials may be utilized. Apart from the diversified fields of adaptation to which the invention may be applicable, as will be apparent from a realization of the features and details of novelty embodied therein, an optimum utilization is illustrated in connection with the dispensing of chemical substances in liquid state, including emulsions, dispersions or the like, by a dispensing means such as that described in the applicants co-pending application Serial No. 290,382, which has matured to Patent No. 2,856,234.
The bottle, comprising the chemical container within the purview of the present invention, is exteriorly threaded at its neck portion for attachment to the internally threaded closure portion of the dispensing means. Where the vehicle comprises a flowing stream of Water, it is subjected to the pressure conditions existing in the water line at the time of operation. The magnitude of this pressure may be quite substantial, under certain conditions exceeding 100 lbs. per square inch. Accordingly the range of pressures encountered within the bottle container, which is determined by that applicable to vehicle flow through the dispenser means may be of such scope that the conventional type of glass bottle is relatively impracticable, in view of its propensity to breakage.
Particularly susceptible to fracture is the neck portion of the bottle in the male threaded area thereof. Thus the threads on the external surface of the neck portion are frequently unable to withstand the stress exerted upon them by the pressure within the bottle directed upwardly against the closure portion of the dispenser means threadedly attached thereto, the resultant breakage of the container in effect rendering inoperative the dispenser combination. An additional source of difliculty, similarly attributable to the prevailing pressure conditions, pertains to the aforesaid female threaded closure portion of the dispenser means, during its attachment to the exteriorly threaded neck portion of the bottle. For example, where the said closure portion is of resinous fabrication, it is occasionally the subject of breakage.
Other objections and shortcomings are likewise applicable to the conventional type bottle containers subject to the aforesaid conditions of utilization. While the difficulties presented may be to some extent diminished through an appropriate choice of the material from which the container or the closure portion of the dispensing means is fabricated, such alternatives may be objectionable either as to their economic feasibility or.practical applications.
It is an object of this invention to obviate such difliculties and uncertainties as hereinabove indicated.
Another object is the production of a bottle manifesting an enhanced resistance to breakage by impact or shock, or by substantial fluid pressures which may be exerted therein in various adaptations thereof.
An additional object is to afford a receptacle embodying novel features of structure and capable of withstanding, substantially without the hazard of breakage, considerable hydraulic pressures in its utilization as an element of a combination with a dispenser means operable under such conditions.
A further object is to attain a glass bottle of sturdy structure and provided with an exteriorly threaded neck portion adapted for coordination, substantially free from the hazard of breakage, with an interiorly threaded closure member comprising the header portion of a dispenser means, operable by the flow therethrough of a vehicle stream, such as water, under considerable pressure, with a by-pass flow from the said stream diverted to the container to effect an equivalent pressure therein, in order to expel a liquid chemical substance from the container for the admixture and distribution with the vehicle.
Other objects, advantages and features of the invention will become apparent from the following description, read in conjunction with the accompanying drawings, wherein similar elements are designated by like numerals.
FIG. 1 comprises a Vertical longitudinal section of a preferred adaptation of the invention, pertinent to the combination of a dispensing means and a bottle of optimum structure, pursuant to the present invention.
FIG. .2 is a longitudinal sectional view of the bottle per se shown in FIG. 1.
FIG. 3 relates to a fragmentary section showing a modified embodiment of an exteriorly threaded neck portion.
FIG. 4 pertains to a plan view of the bottle of FIG. 3, observed from the outlet or opening end thereof.
Among its fundamental aspects, the present invention is predicated upon maintaining at a relatively maximum value the ratio of the threaded contact area, on the exterior neck portion surface of a bottle, with respect to the area of pressure contact by the fluid within the container against the gasket type means and/or closure thereover, the latter area in effect corresponding with that of the bottle opening. Differently stated the total thrust effect applied by the liquid in the container against the resilient gasket or Washer seated in the closure portion of the dispensing means, pursuant to the present invention, is manifested through a minimum area corresponding with the bottle container opening, and the resultant stresses exerted on the neck portion threads are maintained at a minimum value per unit area of threaded surface.
Among the additional attributes of the invention simultaneously elfected, the closure of the container, as in its combination with the dispenser means, is rendered substantially leak-proof despite the material fluid pressures which prevail within the container during the dispersing operation. Moreover by the resort to appropriate structural details in the wall structure of the bottle per se, its amenability to impact or shock breakage may be significantly minimized. Furthermore by the reliance upon an appropriate structural configuration for the container, such as that contemplated by the preferred embodiment of the invention herein, the possibility of any turbulence being contributed by the container wall characteristics to the expelling of chemical concentrate to be dispensed from the container, is materially reduced.
The features and attributes of the invention are herewith more particularly set forth, in the following detailed consideration thereof and of the various figures of the drawing presented. It will be understood that these figures of drawing are submitted as illustrative of either desirable or optimum details of the invention, and are not intended to be limitative of its scope.
. As indicated above, FIG. 1 provides a desirable example of an efficient proportioning dispenser apparatus combination embodying the present invention, the dispenser per se comprising one of the embodiments described in the applicants (so-pending application Serial No. 290,382. It will however be understood that the dispensing means applicable to the combinative aspects of invention disclosed herein is not restricted to that contemplated by FIG, 1, since other embodiments and modifications of dispenser means may be utilized, including the several types illustratively shown in the aforesaid co pending application. In this connection, quite apart from the inventive significance of a dispenser combination exemplified by FIG. 1, the features and attributes of the bottle per se render it applicable to diversified combina tive associations, as well as inventive'per se.
Referring to the structural elements or members of FIG. 1, the conduit 1 may desirably comprise a flow line section or passage adapted for attachment at its end 2 to a source of vehicle supply, desirably water. The portion 4 of conduit 1 is shown angularly disposed relative to the longitudinal portion 3, this relationship being merely to facilitate the connection of conduit 1 with a pipe, spigot or flexible hose line through which the vehicle flows from its source, such as a municipal water main. However there is no intent whatsoever to restrict the configuration of conduit 1, or the correlation of parts 3 and 4 thereof, to any particular design, especially in view of the wide variations and diversifications which will be apparent to anyone versed in the art, and especially in view of the substantial scope of the present invention.
The aforesaid end 2 of conduit 1 may desirably be externally threaded as at 2', for correlation with a connecting means 5, and through the expedient of an internally threaded coupling 6, an attachment of the device to the water main or the like may be effected. The outlet end 7 of'conduit 1 may be externally threaded, and if desired, appropriate coupling means, similar to that indicated at end 2 may likewise be coordinated therewith. Thus the details of end 7 are intended to. conform with any suitable expedients for effecting the attachment of conduit 1 at its outlet end, either directly or through intervening connections and/ or conduits, to any predetermined type of distributing means. Likewise the details of conduit end 2 may be subject to variation, dependent upon the applicable circumstances prevailing with respect to a suitable coordination of conduit 1 with the vehicle supply means.
Within conduit 1, an optimum flow restricting means comprising venturi 3 is provided, the inlet and high pressure side 9 and the outlet or low pressure side 10 of conduit 1 being duly correlated with the venturi throat portion 11. The said venturi 8 may fully conform with the theoretical or mathematically expressed requisites pertinent thereto. It will however be understood, particularly with reference to the present invention, that in lieu of the aforesaid complete or theoretical venturi resort may be taken to other types of fiow restricting means, such as a partial venturi, an orifice plate, or other expedients known to the art.
Downwardly projecting from conduit 1, there is shown a header type member 12 which includes a peripheral flange portion adapted as a closure 13 for attachment to a receptacle or container 14, intended to be supplied with a chemical substance or composition contemplated for dispensing, preferably in the liquid state, embracing emulsions, dispersions, et cetera. The said closure 13is desirably threaded on its internal surface and adapted to receive in appropriate attachment the externally threaded neck portion 15 of the bottle type container, whereby the said container may be removably ailixed to closure element 13 for coordination with conduit 1 through the aforementioned header 12.
A valve controlled port 16 is shown desirably extending from the throat portion 11 of the venturi through the body portion 17 of the header, and opening into pocket or seat 18, adapted to receive the conduit 19, the attachment of conduit 19 with the header 12 in the said seat 18 being effected in any expedient manner, as by a press fit association or a threaded coordination. Thus passage 20 of conduit 19 in effect comprises an extension of port 16, which is appropriately associated with the venturi, the said conduit being adapted for positioning within the bottle container 14.
The said conduit 19 is shown extending substantially to the bottom of the container, and may be comparatively rigid or flexible, the latter alternative permitting it to adjust itself relative to the lowest level of liquid in the container when the latter is maintained at an angular or tilted position. The effect of conduit 19 is to provide the egress passage from container 14 through valve 21 into the venturi 8. On the other hand, the ingress passage from conduit ll, comprising a by-pass or diverted flow of vehicle therefrom into container 15 is determined by conduit 22, which is desirably provided with a capillary port or passage 23. r
The said conduit 22, desirably having an orifice inlet opening, may be attached to the header 12 in any expedient manner. As shown in FIG. 1, the externally threaded portion 26 thereof is coordinated with the internally threaded seat or recess 26' of the header. The said recess 26' is shown extending to the zone 36, the latter being correlated with the opening 31 through the flexible or resilient gasket element 29, fabricated from any expedient material. The said gasket is desirably of a dimension substantially conforming with the maximum diameter of the top end surface at the opening end of the neck portion of the bottle, i.e. measured between the inner and outer peripheral edges of the said top end surface. Conversely the gasket diameter is such that an expedient fitted seating on the entire top end surface 32, determining the opening of the container within the closure means 13, is afforded.
Accordingly the diverted or by-pass flow of vehicle.
from conduit 1 into the container 14 results in ultimately creating a fluid pressure within the said container corre sponding with that applicable to the flowing stream of vehicle within the said conduit 1. The effect of this pressure, pursuant to the embodiment of FIG. 1 is to expel, in predetermined proportion relative to the vehicle stream passing through conduit 1, the chemical substance from the container 14 substantially without any turbulence, through conduit 19 and port 16 into conduit 1 for admixture and distribution with the vehicle stream.
With particular reference to the bottle type container, which per se comprises a significant feature of the invention, as illustratively shown in FIG. 2 the outer or top end surface 32 of the neck portion 15 is provided with an annular head 33, projecting slightly above and of substantially minor area relative to the remainder of the said top end surface, the inner periphery of the bead being substantially contiguous the bottle opening. Thus the opening determined by the bead surface substantially corresponds with the opening 34 of the bottle per se.
The threads 35 on the exterior surface of the container neck portion 15 will be noted, and attention is'directed to the distinct increase in wall thickness of this neck portion, relative to the normal thickness of the lateral walls 36. Similarly a reduction of the internal diameter of the neck portion, as at the said opening 34, is effected, which may be attendant the aforesaid increased thickness of the neck portion 15. The purport of these features is the retention of the surface area of the threaded neck portion of the bottle at a maximum, for example similar to that of the conventional type bottle, while the internal diameter of the neck portion of the bottle, particularly at its opening, is materially reduced, although its ultimate dimension is consonant with the conventional function of a normal bottle opening. The effect of the said diameter reduction comprises a corresponding decrease in the outlet end and an attendant diminution of the total upward hydraulic pressure which may be mani fested through the gasket during the use of the bottle, by way of illustration, in the dispensing operation afforded by the apparatus combination of FIG. 1. The resultant reduction of the total upward thrust on the closure secured to the bottle, such as closure 13 threadedly attached to neck portion 15 of the bottle, makes possible a maximum ratio of the neck portion threaded area to the aforesaid total thrust, the essence thereof being the substantial diminution in the stresses per unit area of thread surface, thereby minimizing any breakage tendency of the said threaded neck portion.
Merely as an illustrative indication of attaining a maximum ratio between the threaded surface area and bottle opening, a conventional type of glass bottle may be considered as having a diameter of approximately 25 mm. between the outer peripheral edges at its opening end, with the diameter being approximately 20 mm. as measured between the internal peripheral edges ofthe bottle at the said opening. Thus the said diameter of 25 mm. will be generally applicable to the surface neck portion of the bottle, upon which the glass threads are integrally imposed, and the wall thickness of the outer or top surface at the opening end is approximately 2.5 mm.
Accordingly a container of such diameter at its surface neck portion, which in its fabrication as by molding, is substantially thickened inwardly to an extent of approximately 6.5 mm. at the top surface thereof, will provide an opening diameter of approximately 12 mm. The result thereof is a reduction in the opening area, relative to the aforesaid 20 mm. opening representative of a conventional type bottle opening, of approximately 64.0%, and a corresponding reduction in the total upward thrust of the liquid pressure aaginst the closure and the intervening gasket at the opening is thereby attained. The
resultant effect is indicated by the ratio, of the proportionate relationship between the surface neck portion area and opening area of the bottle conforming with the present invention to the correspondingrelationship of the conventional bottle, which is approximately 2.78. This comprises an increase in the ratio, of the threaded surface area on the neck portion of the bottle to the opening area, of approximately 1.78, with an attendant diminution in the thrust per unit area exerted on the threaded surface. While the aforesaid figures, indicative of relevant computation results, are submitted to be illustratively applicable, there is no intent to be restricted to their purport or essence, particularly since they are presented herein primarily as a plausible explanation pertinent to the invention herein.
The walls 36 of the bottle shown in the drawings manifest a gradual diverging direction from the neck portion 15 to the base 38, thereby substantially obviating the presence of any distinct shoulders in'the container as a whole. Moreover the lower portion 37 is likewise desirably of a relatively increased thickness with respect to the above indicated, since the various structural features of the container described are of inventive significance quite apart from the aforesaid configuration. It should be noted in this connection that the structural features of the container afford, pursuant to the present invention, a materially enhanced resistance to breakage by impact or shock. Apart from the aforesaid attributes, the increased wall thickness at the neck portion serves to strengthen the area of the bottle to which the surface threads apply. More over, as previously noted, the increased thickness of the neck portion permits the retention of a comparatively large outside threaded surface area for attachment to the internal threads of any closure means cooperating therewith, despite any reduction in the opening area of the bottle, thereby minimizing the stresses per unit area exerted on the said threaded portion of the bottle neck.
With reference to the characteristics of the container 14, quite apart from the inventive features in the neck portion of the bottle as considered hereinabove, the increased base thickness provides a material increase in its strength as well as stabilizing function, for example in regard to the retention of the container in situ with a minimum hazard of being upset. Moreover the preferred embodiment of bottle comprising a frusto-conical configuration, predicated upon a gradual and uniform enlargement of its interior, facilitates the pressure displacement of the chemical liquid content through the neck opening under conditions substantially free from turbulence, as the result of the pressure effected within the container through the by-pass or diverted water vehicle flow from the main conduit 1. By way of distinction, any abrupt or pronounced change in the diameter of the bottle at any portion thereof, as exemplified by container shoul-' ders, would tend to induce turbulence and an attendant mixing function. In addition, it is recognized that'abrupt shoulders comprise a potential weakness in the bottle structure, under conditions of substantial hydrostatic pressures within a bottle, in view of the maximum stresses which prevail at the areas of the shoulder angles.
Indicative of the dimensions of a desirable embodiment of the bottle structure per se, of the configuration shown in FIGS. 1 and 2 of the drawing, the diameter.
between the outer peripheral edges of the top surface at the outlet end thereof may be approximately 25 mm., with the internal diameter determined by the peripheral edges contiguous the opening of the bottle approximating 12 mm; Concerning the thickness of the neck portion, from the maximum of approximately 6.5 mm. at the aforesaid opening end of the bottle structure, there is a reduction to approximately 5.5 mm., which gradually diminishes to approximately 5 mm. at the lower part of the said neck portion. At the jointure between the neck portion 15 and the lateral walls 36 the thickness may be reduced to approximately 3 mm., which value generally pertains for a portion of the length of the lateral walls 36, until there is a gradual enlargement to approximately 4.5 mm. as the lower substantially vertical wall portions 37 are approached, the applicable thickness of the latter desirably being approximately 5 mm. As for the bottom 38, the ends thereof approximate the thickness of the said lower portions 37 and may desirably be approximately 7 mm., whereas the center portion of the bottom may desirably attain the maximum value of 8 mm. While these thickness designations are indicative of a preferred embodiment of the bottle structure, it should be noted that there is no intent to be restricted herein to any particular bottle dimensions, either with reference to the preferred embodiment described, or relative to the conventional type of bottle, since as previously indicated the concept and features of the invention herein are of wide scope and diversified adaptation.
The inner peripheral bead 33 embraced by the top end surface 32, as shown in FIG. 2, per se comprises a sig-.
nificant feature of the invention. Thus it affords a quite satisfactory sealing effect, which is attained by its impressed relationship to the resilient gasket or washer 29, seated on and overlying the aforesaid top end surface 32., when a closure means, such as portion- 13, is secured to the neck portion of the container. Noteworthy in this connection is the materially reduced area. of impressed contact involved in the closure association which comprises primarily the embedment of the annular ridge or bead 33 in the resilient or flexible gasket member. In view of this relatively minor contact area between the bead and the gasket, a minimum force or action is necessary in attaining an effective as well as leakproof co ordination between the closure and the top end surface 32 of the bottle or container, as well as in removing the closure from the container, irrespective of the pressure conditions prevailing within the latter.
Differently stated, on securing the closure to the bottle or container, a relatively small area. of the flexible or resilient washer or gasket is compressed in its contact with the bead 33 per se, when the said gasket is seated on the entire top end surface 32 which embraces the bead 33 at the innerperipheral edge thereof. tion, the top end surface 32 in effect comprises a shoulder slightly below the aforesaid bead 33, and the surface area of primary significance, in attaching the closure to or separating it from the bottle or container under the existing pressure conditions within the same, in essence is that attributable to the contact of the bead 33 with the gasket or washer 29.
Thus the energy required in coordinating the closure means with the outlet end of the container, as by a threaded attachment pursuant to the embodiment shown herein, for attaining an effective sealing function, and particularly the energy essential for effecting the removal of the closure means, notwithstanding the pressure within the container, is largely determined by the relatively minor surface area Contact between the gasket or washer Z9 and the bead 33. The attendant result is to substantially minimize the force which would otherwise be required in the absence of the annular bead orridge on the top end surface, since in the latter situation, the entire area of the said top end surface 32 of the container would be involved in equivalent contact with the full surface area of the gasket or washer. The area of the washer or gasket compressed, to the extent of the presence of the annular bead 33, is a relatively small portion of the entire area of the top end surface 32, embracing the said head, and accordingly the attendant energy requirement is comparatively small with respect to effecting a scaling function, and especially with regard to removing the closure means or cap from the bottle or container under the pressure conditions within the latter.
In addition, and of distinct importance, is the retention through the. expedient of the said head 22 of the total area of the fluid pressure, upwardly directed against the gasket and closure, to the minimum substantially conforming with the diameter of the bottle opening, thereby materially curtailing the stresses on the portions of the container as well as on the closure means coordinated therewith that are secured to each other, and manifest a breakage tendency attributable to the upward pressure thrust from within the container. By the same token the advantage effected in reducing the bottle opening, pursuant to the foregoing description, may be fully attained.
Accordingly it should be quite apparent that the said bead 33 provides a significant function in curtailing the breakage effect on the surface threads or threaded portion of the container, for reasons conforming with the consideration hereinabove relative to the expedient of in wardly thickening the neck portion of the bottle and/ or reducing the opening diameter thereof.
Thus the upward thrust attributable to the internal fluid pressure against the closure threaded to the bottle neck tends to separate the bottle from the attached dispenser means, for example, and this is prevented by the In this connec male thread-s on the neck of the bottle engaging the corresponding female threads on the internal surface of the closure pontion of the dispenser. As the result of maintaining the area of fluid pressure contact at a minimum,
through the effect of the aforesaid inner peripheral head 33 the stresses manifested on the threaded neck portion.
of the bottle are likewise maintained at a minimum value, thereby reducing the breakage tendency.
i In summary, (the significant positioning of the annular.
bead 33 simultaneously affords an enhanced closure and scaling function, and permits the retention of the total fluid pressure area from within the container during its utilization, as in a dispensing combination, at a minimum conforming with that of the container opening. it will be apparent that feature is of material significance irrespective of the manner or type of closure means attachment to the container, and especially where there is a threaded coordination of the closure means with the container as described herein. I
Nevertheless and irrespective of the satisfactory function afforded by annular ridge 33 per se, a desirable modification is shown in FIG. 3 of the drawing. Attention is directed to the additional annular head or ridge 40, which may be embraced by the top end surface 32, positioned at the outer peripheral edge of the said top end surface. A function of the said head 40 is to obviate any possibility of a pivotal or rocking effect of the gasket 29, when it is in impressed contact with the annular head 33, during the attachment of the closure to the bottle container. In addition, annular head 40 provides the leak-inhibiting function supplementary to that afforded by the aforesaid inner peripheral ridge 33.
It should be noted that the concept and essence of the invention as disclosed herein are entirely differentiated from the various structural details which have been contemplated by the prior art in connection with the fabrication of bottles or similar containers. Thus annular beads .or ridges have been provided on the top surface at the outlet end of bottles, the function thereof being exclusively directed to effecting a bermetical seal. Invariably such ridges have been positioned either at the outer periphery of the top surface, or at a position intermediate the outer and inner peripheries. Such a positioning of annular beads or ridges is entirely inconsistent with the concept of the present invention relative to the location of an annular bead at the inner periphery of the top surface, thereby restricting the con-tact area and total hydraulic pressure of the fluid within the container against a superimposed gasket and closure thereover, substantially to the actual area of the bottle opening, such as when.
the container is utilized in a dispenser combination of the type disclosed herein.
' Similarly the thickening of the bottle neck portion and the reduction in the diameter of the bottle opening, pursuant to the present invention, in a manner to attain a maximum ratio of surface threaded area to the aforesaid contact area at the bottle opening, is unequivocally at variance with the sprinkler top type of bottle, both from the standpoint of purport and function, it being especially noteworthy that 81101113. bottle, provided essentially with an orifice opening, is incapable of adaptation in accordance with the invention herein. Thus the features of the invention herein are clearly at variance with the prior art both with respect to the bottle structure per se and as an element or member of a combination, such as that illustratively disclosed hereinaibove. Pursuant to the invention, a novel, sturdy bottle typ container is afiorded, manifesting a significant resistance to rupture through internal hydrostatic pressures of substantial magnitude. A desirable and inventive adaptation thereof is in a dispenser combination as described herein. However as previously noted, containers embodying various structural features herein disclosed are of wide utility. This is evidenced by the significant resistance to impact and shock breakage which pertains to the overall structural features of the bottle per se, independently of any desirable combinative adaptation thereof. Moreover it is apparent that the inventive features of the container herein are adaptable to combinations with other types and modifications of dispenser means which may be attached thereto, especially Where such dispenser means function through the expedient of effecting a substantial pressure Within the container for expelling the content of chemical substance, preferably in liquid form, from the container.
As for the material from which the container may be fabricated, it is preferably of vitreous or glass derivation. However such materials are in no sense limitative, since substantially any other materials utilized in container manufacture may be resorted to, including ceramics and plastics or synthetic resin compositions.
It will be noted that the expression gasket-type means, as referred to herein, is intended to generically embrace gaskets, washers, or the like.
While the invention has been illustratively described in accordance with desirable and preferred embodiments, it is obvious that many changes may be made in the details and features of construction as well as in the combination and arrangement of parts, without departing from the scope or spirit of the invention as defined in the following claims.
