. Mannheim, Germany The present invention relates to dispensers.
More particularly, thepresent invention relates to that type of dispenser which is adapted to dispense a spray of any desired fluid.
It is an object of the present invention to provide a dispenser of the above type with a spray head which enables thecontainer for the fluid to be filled while the spray head is in its operating position, so that the spray head need not be placed in its operating position after filling of the container, and in this way loss of fluid is avoided since positioning of the spray head on a dispenser of the above type may entail discharge of fluid from the dispenser.
' It is, also an object of the present invention to provide a spray head which is capable of producing a relatively short, solid, fine spray.
With the above objects in view the present invention mainly consists of a dispenser for dispensing a spray of fluid, this dispenser including a fluid container having an outlet anda cap means carried by the outlet of the fluid container. A valve means is carried by the cap means for controlling the discharge of fluid from the container, and this valve means has a portion located at the exterior of the container and cap means and carrying a spray head for causing the fluid to issue in the form of a spray, the spray 'head also having a fluid inlet opening and plug means being provided to close the fluid inlet opening after the container is filled with fluid.
The novel features which are considered as characteristic for the invention. are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings, in which:
' Fig. 1 is a fragmentary sectional elevational view of a dispensing structure according to the present invention, showing a special spray head together with a filling plug associated therewith;
, Figs. 2, 3, and 4 illustrate, in fragmentary sectional elevational views, different stages in the use of the spray head of Fig. 1 during and after filling of the container with a fluid to be dispensed;
Fig. 5 is a fragmentary sectional elevational view of a filling structure which may be used to fill a dispenser according to the present invention;
, Fig. 6is a fragmentary-sectional elevational viewshowing the position of" the spray head and valve structure after theIcontainer has been filled;
' Fig. 7 is a fragmentary sectional elevational view showv 2 ing another embodimentof a spray head which is capable of being used in conjunction with the filling of the container; and; I i
Fig. 8 shows the position of the spray head parts of Fig. 8 and the valve structure thereof after the container is filled. '1.
Containers of spray arefilled with a liquid and gas or with a mixture of liquid and gas. The gas may be refrigerated so as to belin liquid formso as to be easily introduced intothe container with the liquid. Conventionally, the spray head is removed during charging of the container, and thenithe spray head is pressed onto the upper part of the dispenser valve. Such pressing of the spray head onto thev upper part of the valve requires depression ,of the valve member to move the latter to its open position, and thus it is unavoidable that with such an arrangement fluid will be undesirably discharged from the interior of the container.
According to the present invention, the spray head is placed in its operating position before the container is charged, and a structure is provided which permits the container to, be charged even though the spray head is in position. Referring to Fig. 1 it will be seen that the container 31 carries a cap. means 32 which clamps to the container a membrane 33 surrounding in a fluid-tight manner a tubular member 44 which extends downwardly from the portion 38 of the valve member 36 and which surrounds the, grooves 39 formed in the portion 38. A sealing ring 35 is fixed to the underside of the upper apertured wall 34 of the cap'means 32, and the valve member 36 is formed with an'axial bore 44, with a transverse bore 43 communicating withthe axial bore 44 and with an annular channel 42 formed by the upwardly extending lip 37 of .an annular flange'on the valve member- 36.. A resilient pjlate 41- urgesthe valve member to its closed position where the lip. 37 engages thesealing ,ring 35. The resilient plate, is clamped at its outer, periphery between theupperface of; the membrane 33 and an elastic sealing ring which engages the underside of a part of the upper-wall of -the cap means 32 as is indicated inFig.l., 1
l A spray head 4 5-ismounted on the upper end of the valve member 36 before the container 31' charged with fluid. Ihis spray head 45 is 'formed with an axial bore 46 which communicates with the bore 44 of'the valve member 36, and a filling plug whose structure is described below is :locateda t .the top open endof the bore 46. Furthermore, the spray head 45 is providedwith a lateral outlet 48 which flares outwardly and which has its inner end 49 of the smallest cross sectional area located at the bore 46. p v a Furthermore, the spray head 45 includes a downwardly extending skirt portion '50 which terminates in a lower annular edge 51 located at a predetermined distance above the container 31 when the valve is closed, as shown in Fig. 1. Thus, with this arrangement when the spray head depressed to open the valve the fluid will flow upwardly through the tube 44 and grooves 3 and between gaps formed in the inner periphery of the resilient member 41 to provide a passage extending from the upper end .of the grooves 39 to the space surrounding the annular flange of the valve member 36, and from this space the fluid will flow into the upwardly directed channel 42, through the bore 43 and axial bore 741, "p.1 I1 a albqrc146;of thesprayhead 45 and out through the outlet 48 thereof. It will be noted that the engagement of the lower edge 51 of the spray head 45 and the container will limit downward movement of the valve member, so that in this way it is not possible for the operator to push the valve member too far into the container.
The filling plug 47 is joined to the spray head 45 before the container 31 is charged with fluid. At the joint between the spray head 45 and the filling plug 47 notches 52 are provided to render the plug 47 easily detachable from the spray head 45 by a downwardly directed pressure applied to the top faceof the filling plug ,47. If desired, the filling plug 47 may simply rest on the upper open end of thebore: 46 to be pressed downwardly, into the latter in the manner: describedbelow.
As is indicated in Fig. 1, the filling plug 47 is formed with an axial bore 53 extending upwardly from the bottom end thereof, and this axialbore '53 communicates with thelateral bore54 which in turn communicates with an annular groove 55 located at the outer surface of the filling plug 47. The distance of the groove 55 from the bottom end of the filling plug 47 is equal to the distance of the inner end 49 of outlet 48 fromthe shoulder formed between the; axial bore portions of the spray head 45 which are of different diameter, as indicated in Fig. 8. In order to charge the container, pressure is applied downwardly against the plug 47 to detach the latter at the weakened places 52 fromthe spray head 45 and to press the filling plug 47 into the bore 46 until the filling plug 47 has the position indicated in Fig. 2, and in this position it will be noted that the outlet 48, 49 of the spray head is closed by the filling plug 47. At this time, a liquid and gas or a mixture of liquid and gas may be introduced into the container through the annular groove 55, the bore 54, the bore 53, and then downwardly along bore 46 and passage 44 through the valve means into the container. After the container is filled, the filling plug 47 is moved downwardly in the bore 46 to the position shown in Fig. 3, and this is the final position of the filling plug 47. It will be noted that in this position the annular groove 55 is located in the same plane as the inner end 49 of the lateral element 48 of the spray head 45, so that the fluid rising upwardly through the axial bore '44 of the valve member 36, when the latter is in its open position, can move upwardly through the bore 53 and out through the lateral bore 54, the groove 55, and the outlet 48.
Figure 4 shows a structure identical with that of Fig. 1 except that a skirt portion is not provided on the spray head 45. In the position of the parts shown in Fig. 4, the filling plug 47 is located at the top end of-the bore 46 and is ready to be broken away at the weakened portion 52 of its joint with the spray head 45 when the plug 47 is moved downwardly into the bore 46. The filling structure includes an elastic element 56 which is shown in Fig. 5. This elastic element 56 is placed about and pressed against the spray head 45 so that the elastic member 56 is deformed and conforms to the outer configuration of the spray head and closes the outlet 48 thereof. It will be'noted that the elastic element 56 provides in its interior a chamber 57 which surrounds the filling plug 47 and which does not communicate with the outer atmosphere due to the pressure of the elastic member 56 against the top face of the spray head 45. The filling structure furthermore includes a ram 58 which is formed with an'axial bore 59 and with lateral bores 60 communicating with bore 59 and located adjacent the bottom end of thefilling ram 58. This filling ram 58 is movable downwardly through the elastic member 56 and is aligned with the filling plug 47, so that when the ram '58 is moved downwardly into engagement with the plug 47 the latter can .be detached from the spray head 45 and shifted downwardly to the position shown in Fig. 5, this position corresponding to that shown in Fig. 2. In this position of the parts a liquid and gas 4 or a mixture of liquid and gas may be introduced through the bore 59 to flow out through the opening 60 into the chamber 57 and from the latter through the annular groove 55 and bore 54 down through the bore 53 and bore 56 into the passage 44 of the valve 36 and so on into the container. After the filling operation is completed, the ram 58 is moved downwardly so as to shift the plug 47 to its final position indicated in Fig. 6 as well as in Fig. 3, and then the dispenser and filling structure are separated from each other and the device is ready for use. It will be noted from Fig. 6 that during the filling of the container 31, the downward pressure applied to the spray head by the elastic member 56 causes the valve to be in the open position indicated in Fig. 6.
Figs. 7 and 9 show another embodiment of a valve structure and spray head arrangement according to the present invention. As may. be seen from Fig. 7, the spray head 45 therein includes a skirt portion connected to the remainder of the spray head by a frustoconical hollow portion 50, and the bottom edge '51 of the skirt portion engages the container to limit the downward movement of the valve member 36. This valve member 36 of Fig. 7 extends above the inner end 49 of the lateral outlet 48 of the spray head 45. In this case the axial bore 67 of thevalve member 36, which is otherwise identical with the above described valve member 36, communicates with alateral. bore 66'which in turn communicates with an outer annular groove 65 of the valve member 36, and this groove 65 is located at the plane of the inner end 49 of the lateral outlet 48, so that in this way the latter communicates through groove 65 and lateral bore 66 with the axial bore 67 of the valve member 36.
The spray head 45 is formed with an axial hole which receives the upper end of the valve member 36 and which extends upwardly beyond the same-to provide the chamber 73, this chamber 73 having at its bottom end a downwardly directed. surf-ace which engages the top end of the valve member 36 at 72;, as shown in Figs. 7 and 8. The upper end of the axial bore of the spray head 45 is enlarged and. a plurality of fins 69 are located in the upper portion of the bore of the spray head 45, these fins 69 being formedintegrally with the spray head and extending radially toward the axis thereof, the fins 69 being distributed about this axis and defining between themselves passages 68 which communicate with the chamber 73 and through the latter with the axial bore 67 of the valve member 36. The inner ends 71 of the fins 69j'are joined to a plug 70 which may have any desired configuration, the plug 70 being elliptical in the example shown. However, this plug may, for example, be spherical. At .the joint 71 between the plug 70 and the fins 69, thematerialof the spray head 45 is weakened as by being formed with suitable notches, grooves, or the 'like,.so that the plug 70 iseasily detachable from the spray head 45. With this structure the container is filled in the manner described above while the parts have the position shown in Fig. 7. In other words with this arrangement, the elastic member 56 shown in Fig. 5 will surround the upper part of the spray head so as to close the outlet 48, :but the ram 58 whose interior communi cates withthe passages '68 is not lowered to an extent sufircient to break the plug 70 from the fins 69. during the filling of the container. After the container is filled, the ram 58 is lowered so as to detach the plug 70 from the fins 69, and the ram 58 is actuated to lower the plug 70' until it has the position shown in Fig. 8. The outer diameter of the plug 70 is great enough to cause it to be inserted with a press fit into the upper end of the bore 67 so that the upper end of this bore is closed in a fiuid t-ight manner by the plug 70, and in this way, after the container is filled, the fluid can escape therefrom only through the outlet 48 after the valve 36 is opened. Thus, the spray head has the structure shown in Fig. -8 after the container is filled.
. ,Vhile the invention has been illustrated and described as embodied. in'fiuid dispensers, it is not intended to be limited to the details shownfsince various modifications and structural'chan-ges may be madewithout departing in any way from the spirit ofthe present invention.
Without, further analysis, thetoregoing will so fully reveal the gist'of the present invention that others can by applying current knowledge readily adapt it for various applicationswithou't oniittin fea ur s that gfrohnthe stand oint of prior antainy constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
