IRELAND BY JWV ATTORNEYS United States Patent 3,462,019 STORAGE, DISPENSING AND FILTERING BAG Jack W. Ireland, 485 North Ave., Tallmadge, Ohio 44278 Filed Sept. 12, 1966, Ser. No. 578,807 Int. Cl. B01d 35/28, 35/16 US. Cl. 210-244 3 Claims ABSTRACT OF THE DISCLOSURE This invention relates to the art of containers and in particular has reference to an improved type of plastic bag that is provided with storage, dispensing and filtering means as an integral part of the same.
While the improved bag of this invention is adaptable to use in several areas, it has been found that the same has particular utility in connection with the storage, transportation, mixing and dispersion of zinc powder that is used as major constituent of certain protective metal coatings.
While zinc powders of this type have enjoyed a high degree of success as a protective coating for metals, there have nonetheless been certain difiiculties that have been encountered with regard to the transporting, admixing and application of such powders under field conditions that are encountered during actual usage.
From a standpoint of transportation, ditficulty is encountered in that the conditions of storage, such as the high humidity of a ships hold, can have an adverse effect on the material if the same is not properly protected.
From the standpoint of mixing, the same has heretofore been done by repetitive spooning of small amounts into the proper solution, followed by stirring until a uniform coating solution is obtained. The principal problem that is encountered here is that such spooning invariably results in the creation of small agglomerates of zinc powder that are not properly dissolved into solution. Further, these powders being mixed in the open are often subject to the influence of high winds and the like with the result that substantial amounts of the powder in question are blown away and therefore lost during the conventional admixing procedures that have heretofore been employed.
Finally, and with regard to the application, it is believed apparent that the aforementioned agglomerates are capable of causing problems of application in two separate and distinct manners. First, it has been found that such agglomerates oftentimes tend to clog the average nozzle of spray equipment that is used to apply the zinc powder solution onto the metal that is being protectively coated.
Secondly, and in the event that the agglomerates pass through the nozzle the same will invariably be applied over the coating as an undissolved lump of zinc oxide with this lump readily deteriorating in a minimal time so as to in effect create a void in the protective coating that detracts from the over-all effectiveness of the same.
3,462,019 Patented Aug. 19, 1969 In has been discovered that the disadvantages of the known prior art can be overcome by providing a container that, in addition to serving as a storage vehicle for the powder until its time of use, further includes selfcontained filtering means that may be employed for the purpose of filtering or screening the material after the same has been admixed into the solution. In this regard, the filtering means are normally inactivated within the interior of the bag during shipment and storage of the powder, with the powder first being removed and placed in solution whereupon the bag may be slightly altered to expose the filtering means so as to permit the solution to be filtered into an appropriate container for use as a protective coating.
Production of an improved filtering bag having the above characteristics accordingly becomes the principal object of this invention with other objects of the invention becoming more apparent upon a reading of the following brief specification, considered and interpreted in the light of the accompanying drawings.
Of the drawings:
FIGURE 1 is a side elevation of the improved container in its unopened position with zinc powder being contained therein.
FIGURE 2 is a sectional view taken along the lines 2-2 of FIGURE 1.
FIGURE 3 is a sectional view taken along lines 3-3 of FIGURE 1.
FIGURE 4 is an elevational view showing a corner being removed for the purpose of dispensing the bag contents.
FIGURE 5 is a view similar to FIGURE 1 but showing the top portion of the bag being cut away for the purpose of receiving a solution of material to be filtered from the bag.
FIGURE 6 is an elevational view of the bag showing the lower end of the bag having been severed so as to permit extension of the filtering means to the full line position shown.
Referring now to the drawings and in particular to FIGURES 1 and 2 thereof, the improved bag, generally designated by the numeral 10, includes opposed sheets 11 and 12 of flexible impervious material that are joined at their edges to form the completely sealed container, with the preferred form of the invention indicating that the sheet material 11 and 12 be of a plastic material so as to facilitate heat sealing at the edge portions thereof as indicated by the numeral 14 in FIGURE 2 of the drawings. It is to be understood, however, that the material employed could be altered in accordance with well known practices.
Before commencing with a detailed description of the bag, it is to be noted that, as previously indicated, the improved bag 10 provides the three-fold function of (1) dispensing material (2) serving as a container within which solutions of the material may be stored and (3) filtering the stored material out of the container under proper conditions of admixture.
Because of the fact that the bag is initially completely closed so as to store the powder material therein for transportation to the point of use, it is, of course, necessary that various cutting or other severing operations must be effected on the bag in order to permit performance of the above enumerated functions.
Thus, and for the purpose of convenience of description, the bag 10 will generally include a dispensing portion D (which merely involves severing of an edge portion, as shown best in FIGURE 4); a loading portion L (which merely comprises the severed open end as shown best in FIGURE 5); and a filtering portion F which is defined by the line XX in FIGURES 3 and 5 (with the open filtering portion being best shown in FIGURE 6).
It is to be understood that the just described bag portions D, L and F may be selected somewhat at random, although it is imperative that the bag be contoured to the appropriate shape required to permit these severed portions to perform their respective functions.
While the bag 10 is of generally rectangular shape, the preferred embodiment of the invention contemplates that the same be cut ofl or tapered along the edge so as to form a funnel-like configuration in the lower region of the bag 10 as viewed from FIGURE 1.
In this regard and referring to FIGURE 3, the lower edge 16 of bag 10 is shown having a heat sealed region 14a that serves to seal the lower end of the bag in the manner similar to the sealing method employed for the remaining edges. However, for the purpose of providing filtering means, the bag walls 11 and 12 have a funnelshaped filtering device 20 of cloth or other filtering material stitched or otherwise secured thereto as best shown in FIGURES 3 and 5. As indicated above, this filtering device is generally of triangular shape and is invaginated Within the bag so as to be collapsed to known form that avoids interference with the bag contents.
In use or operation of the improved filtering bag, it will first be assumed that the bag has been manufactured as discussed, with the filtering means 20' being stored within the confines of the fully closed bag 10 that will also have stored therein the zinc powder that is being transported. When it is desired to mix the powder, it is merely necessary that one of the upper edge corners be cut in the dispensing portion D, at which time the contents of bag 10 can be carefully dispensed in the manner illustrated in FIGURE 4, with these contents being discharged into a suitable container, at which time admixing to the formulation required can be achieved by the use of the appropriate mixing fluid.
With the contents emptied and admixed as just described, the upper portion of the bag may be completely cut off in loading portion L so as to, in effect, provide an open ended funnel-shaped container within which the just described admixture or slurry may be received as shown in FIGURE 5. When the slurry contents of the mixing container has been transferred to the bag as shown in FIGURE 5, it is merely necessary that a cut be taken along the lines XX, at which time the filtering means 20 can be pulled out to permit strained emission of the mixture as shown in FIGURE 6.
It is believed, of course, apparent that while the bag has been destroyed from the standpoint of reuse for storage that the filtering portion of the same could be reused if desired.
It will be seen from the foregoing how there has been provided a new and improved type of storage, dispensing and filtering bag that serves the multi-fold purpose of transporting the material to the site in proper condition,
as wellas providing a vehicle-for mixing anifilteringthe so long as the same performedthe inherent function of being impervious to air and moisture; Similarly, whil'the filtering device 20 has been shown as being ofa'triangular configuration located near the mouth of thefunnel-like portion of the mixing bag 10, it is tobe understood that the shape and arrangement of the component parts could be modified if desired without departing from the scope of the teachings herein being disclosed. I
Accordingly, modifications of the invention may be resorted to without departing from the spirit hereof or the scope of the appended claims.
What is claimed is: 1. An expandable storage, dispensing and filtering bag of the character described, comprising:
(A) an air and moisture impervious flexible container initially defining a fully closed interior volume and having (1) dispensing (2) loading and (3) filtering portions; (B) a flexible filtering screen (1) disposed initially interiorally of said with its edges secured thereto; (C) said filtering portion of said container adapted to container be opened whereby access to the interior of saidcon- 3. The device of claim 2 further characterized by the fact that said container tapers to a funnel-like configura tion adjacent said filtering portion thereof.
