Description
This invention relates to a device suitable for fluid discharge of containers. This device is suitable both for draining and rinsing of containers.
More particularly, this invention relates to a hand 5 held integral device which can be used to drain and rinse containers which are used for storing chemicals.
These chemicals are generally hazardous either to the handler or the environment and may be industrial chemicals such as pesticides, activants, emulsifiers, lo additives, surfactants, adjutants, solvents and the like, or may be waste products of industrial processes.
Pesticides are fairly widely used in various industries, ranging from herbicides to insecticides, etc., and these find widespread use especially in 15 agricultural or farming operations. Pesticides are normally retailed in containers ranging from one gallon or less to several gallons, which the user then dilutes for tank application. Disposing of containers, which have retained pesticides, can be critical particularly - 20 if the container has been employed to hold highly toxic chemicals.
Currently, many of the containers used for pesticide purposes are merely discarded after their contents have been emptied, without taking any special 25 precautions to remove any residual pesticide in the container. Containers disposed of in this way could pose a hazard, and for this reason amongst others, it has been recommended in the industry to rinse the containers to remove any pesticide residue remaining.
30 In addition, recovery of any pesticide remaining in the container by rinsing has economic advantages in that more active chemicals can be recovered. While pesticide containers are envisaged as the typical container, with which the device of the present invention can be used, 35 it is apparent to those skilled in the art that the ~2~3~
invention applies to other chemical containers generally.
The device of this application can not only be used to rinse containers but also can be used for fluid extraction or drainage of containers, especially pesticide containers. In the case of pesticides, usually the container's contents are poured into another receptacle (for example, a spray tank) and the container is then rinsed and disposed of. However pouring is time consuming and awkward besides with larger container sizes as is rinsing and a more efficient method if needed. Also, suction drainage of the contents e.g. by pump or siphon is more convenient but can be dangerous.
Conventionally, rinsing can be carried out by merely adding water to the container, shaking thoroughly then draining the resulting material from the container.
However, to be effective, such rinsing should be carried out a minimum of three times before the container is discarded.
In rinsing containers, as noted above, water is normally added to the containers by means of pouring the desired quantity of water into the container through a funnel, or alternatively by placing a hose in the container opening and filling it. Inasmuch as most pesticide is located on the side-walls and bottom of the container (as opposed to the top-wall), rinsing is considered generally to be effective resulting in only minor amounts of pesticides remaining in the container after triple rinsing. On the other hand, to avoid any possible reuse of the containers, even after being rinsed, it has been recommended that the containers be punctured or otherwise rendered unusable, which is a further step which has to be undertaken by the user following rinsing.
-~3~0~>
It would be desirable if the objective of discharging and rinsing pesticide containers could be carried out by the use of an attachment which could be readily mounted on a hose or the like supply of a fluid for rinsing pesticide containers, and which would eliminate the need for triple rinsing of the container;
such a device could also optionally have means for rendering such container useless; to this end applicant has developed in one embodiment a device to be hand held for conducting fluid which is suitable for discharging and rinsing pesticides, which device contains a body having opposed ends with a fluid passage in said body, and first and second fluid conduit means in communication with said passage at one end of said body, said body having in this embodiment container rupturing means at the other end of said body and extending therefrom, and adapted to be inserted into the container, a fluid passage in said container rupturing means in communication with said passage of said body, and third fluid conduit means in said container rupturing means in communication with said fluid passage means in said container rupturing means, whereby when . said rupturing means is-inserted into a container, said : third conduit means is effective for said fluid to flow there through, both into and out of said container.
In a further embodiment of the present invention, the body of the device described above may, in place of the container rupturing means, be provided with a shaft or a terminal portion which is adapted to be inserted into the container through a manufacturer's opening (i.e. the pouring mouth) so that in this case, rather than utilizing the rupture means to puncture an opening in the container, the normal opening used for dispensing the container contents may be employed and the same rinsing function can be utilized by employing applicant's device.
12~ 5 In both embodiments, the end of the body of the device is inserted into the container and then operated as described hereinafter in greater detail. In conjunction with the above, the body of the device may be provided with a seal or abutment - seal to position the device at a given depth in the container, and to prevent back-splashing of the container contents when rinsing occurs. Such a seal can be mounted at the desired position, or may be adjustable mounted to accommodate containers of different sizes.
In a still further embodiment of the present invention, the portion of the device which is adapted to be inserted into a container may be composed of various sections to provide an adjustable length, such as in the case of a telescoping portion, whereby the body may : mount, e.g. a shaft which can telescope to provide different lengths. Telescoping sections may comprise two or more sections as desired, one fitting within the other. Likewise, as applicant's device includes fluid conduit means within the body, or the shaft, in the case of an adjustable shaft or a telescoping shaft, the fluid passages can be likewise constructed in a fluid-type manner.
In greater detail of the present invention, the device has a main body integral which is adapted to be hand-held, and to which a fluid passageway or channel extends from one end to the other. One end of the device may be adapted for mounting or connection to a supply of fluid such as a hose or the like by suitable connecting means (e.g., couplings or the like); such means being connected to said first and second fluid conduit means; one embodiment of the present invention ; in preferred form includes in the first and second conduit means valve means associated therewith said device for providing the desired control of the flow of fluid. Such valve means may be any conventional valve ~2~0~
means for this purpose; preferably such valve means will provide for on-off flow capabilities with varying flow control between the "on" and "off" positions capable of handling the desired fluid flow pressure, for example, 35 to 40 psi. Such valve control means can be incorporated into the device of the present invention as integral pyrites thereof or alternatively may-be coupled between the device of the present invention and a source of fluid, on the inlet line, and a source of suction, on the outlet line, by mounting the valve(s) between the device and the source of fluid and the source of suction, by coupling means and the like.
The device of the present invention has, in one embodiment, and as one of its features, container rupturing means forming an integral part thereof and which comprises a sharp puncture tip connected to the body and formed of suitable material to enable the same to rupture any container made of conventional material which typically include plastic or metal. The puncture means preferably comprises an extension of the body of the same or different material as the body, terminating in a pointed tip. A preferred embodiment comprises a tube-like extension of the main body, having an acute angled end portion, which is preferably made of metal or plastic. The two-like extension can be in the form of a shaft connected to the main body. In the other embodiment of the present invention, where no container rupturing means is provided, the shaft may terminate in a blunt point, and be dimensioned so as to fit in a conventional container opening.
As outlined above, the main body includes a fluid passage extending there through in communication, at one end of the body, with the first and second fluid conduit means, and at the other end with the third fluid conduit means, which can be indifferently used as a discharge (or outlet) means, and extraction (or inlet) means.
Preferably, the main body comprises a cylindrically shaped member which enables the device to be held by hand, so that the main body may have a suitably shaped cylindrical central portion, recessed inwardly from the balance of the body.
Preferably a seal, journal led to fit around the container rupturing means of the device, is provided When the device is in extraction or rinsing mode this seal is pressed against the outside of the container, thus minimizing spillage and fluid loss. The seal may also be positioned so as to permit the device of the present invention to be inserted into a container to a given depth; as noted above, adjustable seals may be provided to permit the depth of insertion into the container to be varied according to the size and type of - container. In this manner, and in the embodiments described hereinafter, various size containers can be accommodated using a single device of an adjustable nature. Although, ideally, each device will exactly correspond in size to a specific container size, so that the seal will fit closely, in practice it is desirable to provide means to press the seal against the outside of the container. In more preferred form this is ; achieved by providing a helical spring between the body and the seal, radially surrounding the container rupture means, adapted to thrust or press the seal against the outside of the container.
In an even more preferred form both container rupture means and spring properties are tailored to a specific (common) size of container, e.g. the container rupture means may be designed for a five gallon container so that when the container is penetrated the rupture means extends from bottom to top of the container, and the seal is tightly held against the top of the container. This tailored form while designed for a five gallon container will be equally effective for 12~36.~
smaller containers, in that the seal will be pressed down against the top surface of the container by the helical spring, in this instance it is expected that the "five gallon" device will operate effectively on one gallon containers and in some cases smaller containers.
The spring, an optional feature of the present invention, can take different shapes e.g. a helical spring or other compression means.
As an optional feature of the present invention, the device may incorporate means for measuring the amount of fluid in a container, either for use during operation of the device of the present invention or pro-or post-usage for, e.g., determining the amount of rinse liquid in the container. Conventional gauges for this purpose may be employed or alternately, may be ; incorporated directly into applicant's device by using e.g. a hollow tube open at one end to permit access of the container contents into the tube, enclosed at the other end with a gauge or the like. Another form of a gauge which may be employed is to provide a separate attachmellt mountable on the body or projection, or even the body and/or projection per so, may be provided with appropriate markings to indicate fluid level.
Having generally described the invention, reference will now be made to the accompanying drawings illustrating preferred embodiments and in which;
Figure 1 is a perspective view of a device of the present invention showing a portion of the body in cut away view, and indicating passages within the device;
Figure 2 is an end view of the device of Figure 1 from the direction of the container rupturing means;
Figure 3 is a perspective view showing use of the device in draining and rinsing a pesticide container.
Referring to Figures 1 and 2, a device of the present invention comprises a body indicated generally by reference numeral 10 which has a gripping portion iffy formed as a recess in the body and indicated by reverence numeral 12. A pair of spaced apart portions 14 and 16 are provided on the body, and which will be described hereinafter in greater detail.
Extending through the body 10 is a fluid passageway indicated by reference numeral 18, and which is in communication with fluid passageway 20, which in this case is sealed at end 21, two conduits 23 and aye are formed in the side of passage 20 which may have threads 33 and aye for the purpose ox receiving a valve member, in the device illustrated nipples 34 and aye are threaded onto 23 and aye respectively by internal threads (not shown), and valve bodies 35 and aye are connected to the nipples, hose barbs 37 and aye are threaded onto the valve bodies. The valves are - controlled by handles 36 and aye. The body 10 and passageway 20, and conduit 23 and aye may be integral if desired. although end 21 is shown as a sealed end, one conduit can be placed at end 21 linear with passageway 20, while the other can be perpendicular to passageway 20. The passageway 20 and conduits 23 and aye may, for example, also form a "T" joint, with for example each conduit forming half a cross arm of the "T", the precise form that the conduits 23 and aye and passageway 20 is not critical, the forms indicated being especially preferred embodiments.
The container rupturing means in the preferred embodiment shown comprises a metal tube 22 projecting from the end of the body 10 opposed to passageway 20;
this tube 22 has piercing means 24 formed by an acute angled planar section across tube 22. The tube 22, has a fluid passage which is in communication with passage 18 of body 10. The end of tube 22 at piercing means 24 is open, as indicated by reference numeral aye, and thus forms a continuous passageway with passageway 18 and 20.
In the embodiment where a piercing tip is not employed 12~
g and where e.g. the tube 22 would terminate in a flat or blunt end, the passageway aye may exit from the side of the tube 22 adjacent it's free end - likewise, in the version shown in Fig. 1, the passageway aye may exit from the side as opposed to the end of the tube. The opening in the tube 22 provides a third fluid conduit for extraction of fluid from, or discharge of fluid into, a container.
A seal 32 is also provided which is journal led on tube 22 and surrounds it peripherally. An optional helical spring 28 is provided between seal 32 and shoulder I of body 10. The helical spring referable has circular ends (not indicated) to provide even pressure against seal surface 40 and shoulder 26. The ; 15 body spring end may rest in the recess formed by shoulder 26 extending outwardly and radially of the body 10 and by further shoulder 27. Seal 32 is preferably provided with a downwardly and outwardly tapering side-wall (Figure l); member 32 is adapted to face against the wall of the container and to prevent any spray exiting from the container.
In the embodiment illustrated in Figure 1, the device is provided with two valves 35 and aye. The particular version shown has handles 36 and aye, which will open and close valves 35 and aye respectively, in this case the valves are connected by nipples 34 and aye to conduits 23 and aye, and themselves are connected to hose barbs 37 and aye. Alternatively, the structure shown in Figure 1 may utilize "T" configuration as opposed to having hose barbs 37 in the configuration.
As shown in figure 3 hoses 38 and aye from fluid supply means can be conveniently attached to the device by appropriate means. As shown one person may use the device without having to reach for remote on-off controls.
In use the valves 35 and aye are initially both 12~ I
closed. The pesticide container indicated generally by reference numeral 48, typically of several gallons for industrial purposes, and normally made of plastic or sheet metal. The typical container includes a cylindrical side wall and top wall 50 and bottom wall 49. To this end container rupturing means, tube 22, is thrust, using piercing means 24, through top wall 50 and the device inserted until piercing means 24 touches or is adjacent to bottom wall 49. Spring 28 is compressed by this action forcing seal 32 against top wall 50.
At this point the valve 35 of suction line 38 is opened, and the pesticide extracted or drained to tank or similar storage means (not shown). The valve 35 is then closed, and valve aye of fluid (water) line aye is then opened to allow rinsing of the container 48. When 48 is full of fluid valve aye is closed, and valve 35 opened to drain the pesticide residue to the tank or similar storage means.
For ease of puncturing the container, the body 10 of the container is provided with the outwardly protecting portion 14 which is provided with a shoulder so that a force may be exerted on the device to push it through the container wall. In like manner, the gripping device is provided with an abutment 16, which may be used to pull the device from the container.
Although the invention is described with respect to small rupturable containers of the two lithe and upwards pesticide container, it is understood that this can be applied to larger containers up to fifty five gallon (about 250 lithe) drums, which contain general industrial chemicals or waste products. In the cases where there is a burg hole this may be used to suction extract or drain the container without rupturing it first.
It will be understood that various modifications can be made to the above described embodiments without ~233~
departing from the spirit and scope of the invention as described herein.
More particularly, this invention relates to a hand 5 held integral device which can be used to drain and rinse containers which are used for storing chemicals.

The ; 15 body spring end may rest in the recess formed by shoulder 26 extending outwardly and radially of the body 10 and by further shoulder 27. Seal 32 is preferably provided with a downwardly and outwardly tapering side-wall (Figure l); member 32 is adapted to face against the wall of the container and to prevent any spray exiting from the container.
In the embodiment illustrated in Figure 1, the device is provided with two valves 35 and aye. The particular version shown has handles 36 and aye, which will open and close valves 35 and aye respectively, in this case the valves are connected by nipples 34 and aye to conduits 23 and aye, and themselves are connected to hose barbs 37 and aye. Alternatively, the structure shown in Figure 1 may utilize "T" configuration as opposed to having hose barbs 37 in the configuration.
As shown in figure 3 hoses 38 and aye from fluid supply means can be conveniently attached to the device by appropriate means. As shown one person may use the device without having to reach for remote on-off controls.
In use the valves 35 and aye are initially both 12~ I
closed. The pesticide container indicated generally by reference numeral 48, typically of several gallons for industrial purposes, and normally made of plastic or sheet metal. The typical container includes a cylindrical side wall and top wall 50 and bottom wall 49. To this end container rupturing means, tube 22, is thrust, using piercing means 24, through top wall 50 and the device inserted until piercing means 24 touches or is adjacent to bottom wall 49. Spring 28 is compressed by this action forcing seal 32 against top wall 50.
At this point the valve 35 of suction line 38 is opened, and the pesticide extracted or drained to tank or similar storage means (not shown). The valve 35 is then closed, and valve aye of fluid (water) line aye is then opened to allow rinsing of the container 48. When 48 is full of fluid valve aye is closed, and valve 35 opened to drain the pesticide residue to the tank or similar storage means.
For ease of puncturing the container, the body 10 of the container is provided with the outwardly protecting portion 14 which is provided with a shoulder so that a force may be exerted on the device to push it through the container wall. In like manner, the gripping device is provided with an abutment 16, which may be used to pull the device from the container.
Although the invention is described with respect to small rupturable containers of the two lithe and upwards pesticide container, it is understood that this can be applied to larger containers up to fifty five gallon (about 250 lithe) drums, which contain general industrial chemicals or waste products. In the cases where there is a burg hole this may be used to suction extract or drain the container without rupturing it first.
It will be understood that various modifications can be made to the above described embodiments without ~233~
departing from the spirit and scope of the invention as described herein.
