VACUUM CLEANER FILTER BAG AND THE METHOD OF FORMING SAME Filed Oct. 22, 1965 United States Patent 3,457,706 VACUUM CLEANER FILTER BAG AND THE METHOD OF FORMING SAME John J. Fesco, Baldwin, N.Y., assignor to Studley Paper Company, Inc., a corporation of New York Filed Oct. 22, 1965, Ser. No. 500,684 Int. Cl. B01d 29/10 U.S. Cl. 55-367 The present invention relates in general to vacuum cleaner filter bags and in particular to a generally improved collar therefor.
Vacuum cleaner filter bags made of filter paper or other similar material are in wide spread use in connection wiht vacuum cleaners. Such filter bags are expendable and are usually provided with a collar which adapts the bags for mounting within the vaccum cleaner so as to receive the output end of an air intake conduit. Heretofore, the operation involved in securing the collar to the open end of the vacuum cleaner filter bag was generally a relatively complex, time-consuming and expensive operation.
In view of the foregoing, it is an object of the present invention to obviate the stated disadvantages of prior art vacuum cleaner filter bags.
In accordance with the foregoing object of the present invention, it is another object to provide a generally simplified and eflicient method for securing collars to vacuum cleaner filter bags.
It is another object of the present invention to provide a generally improved collar for a vacuum cleaner paper filter bag which will prevent the mouth of the bag from becoming distorted and which in addition will provide added support and reinforcement for the bag at the open mouth thereof.
It is a still further object of the present invention to provide a highly novel collar for a vacuum cleaner filter bag which collar is also provided with means for closing the open mouth of the bag so as to prevent inadvertent discharge of the contents thereof.
Other and further objects and advantages of the present invention will be readily apparent to one skilled in the art from a consideration of the following specification taken in connection with the appended drawings.
In the drawings, which illustrate the best mode presently contemplated for carrying out the present invention,
FIGURE 1 is an exploded view of a vacuum cleaner filter bag provided with a collar pursuant to the present invention;
FIGURE 2 is a view which illustrates the method of securing the collar of the present invention at the open mouth of the bag;
FIGURE 3 is a fragmentary perspective view of a vacuum cleaner paper filter bag provided with a collar pursuant to the present invention, portions being broken away for purposes of illustration;
FIGURE 4 is a fragmentary side view of a vacuum cleaner paper bag pursuant to the present invention with portions broken away for purposes of illustration;
FIGURE 5 is a sectional view taken on the line 55 of FIGURE 3; and
FIGURE 6 is a sectional view taken on the line 6-6 of FIGURE 3.
Referring now to the drawings in detail, there is shown a vacuum cleaner filter bag 10 preferably formed of filter paper or other suitable material. The bag 10 is provided with a front wall or panel 12 and with a rear wall or panel 14 and with a pair of end wall gussets 16 and 18. The end wall 16 is provided with an infold 20 and the opposite end wall 18 is provided with an infold 22. As best shown in FIGURE 6, the bag 10 is provided with a turned-up and closed bottom 24 and as 4 Claims "ice best shown in FIGURE 1 the bag is provided with an open top 26. As here shown, the bag tapers inwardly from the open top 26 to the closed bottom 24. However, it will be understood that it is not essential for the present invention that a tapered bag 10 be used, it being within the concept of the present invention to use bags which are also not tapered.
Pursuant to the present invention, the bag 10 is provided with a collar 28. The collar is preferably formed of cardboard or paperboard or any other suitable material. As here shown, the collar 28 is essentially of rectangular conformation and is provided with a rectangular rim 30. The rim 30 has the opposing integral elongated rim portions 32 and 34 which are interconnected by the shorter transverse rim portions 36 and 38. The elongated rim portion 32 is provided with a hinged quadrilateral flange 40 and the elongtaed rim portion 34 is provided with a similar quadrilateral hinged flange 42. The transverse rim portion 36 is provided with a triangular hinged flange 44 and the transverse rim portion 38 is provided with a triangular hinged flange 46. It will be understood that the collar 28 is formed from suitable sheet material stock, which as previously indicated, is preferably cardboard or paperboard, and the collar is cut or stamped from said stock. Conventional paper-bag making machinery can be utilized to form the rim 30 and the hinged flanges 40, 42, 44 and 46 thereof. Viewing FIGURE 1, it will be understood that the various hinged rim flanges can be bent inwardly, as indicated by the arrows 48, from the plane of the respective rim portions, it being noted that the various rim portions are integral with each other and that each flange is integral with, although bendable from, its associated rim portion.
FIGURE 2 illustrates the manner in which the collar 28 is secured to the bag 10. For this purpose, a block 50 of wood or other similar material is used, The block 50 has a rectangular conformation which is similar to the conformation of the collar 28. However, the block 50 is of smaller rectangular area than the collar 28, the surface 52 of the block having an area equal to the combined areas of the flanges 40, 42, 44 and 46 so that if the collar 28 is deposited on the block surface 52, the rim 30 of the collar will extend outwardly of the block. More specifically, the upper surface of the collar 28, which is the surface which appears uppermost in FIG- URE l, is deposited or positioned on the block surface 52 which, as shown in FIGURE 2, is the upper surface of the block 50. Consequently, it will be apparent that the lower or undersurface of the collar 28 will be uppermost when the upper surface of the collar is positioned on the upper surface 52 of the block 50. A suitable adhesive 54 is applied to the under or exposed surfaces of the flanges 40, 42, 44 and 46, the adjacent surfaces of the various rim portions being free of the adhesive. It will be understood that when the top 26 of the bag 10 is fully opened or expanded, the top of the bag will encompass an area which is substantialy equal to the rectangular area encompassed by the four flanges 40, 42, 44 and 46, so that it will be understood that the area encompased by the fully opened upper end 26 of the bag does not encompass the full area of the collar 28 incuding the rim 30. With the adhesive coated undersurfaces of the flanges uppermost on the upper surface 52 of the block 50, the bag 10 is moved downwardly as indicated by the arrow 56 in FIGURE 2, to engage the collar 28. More specifically, the bag 10 will engage the collar 28 along the hinge lines 58 of the respective flanges and as the bag is continued to be moved down in the direction of the arrow 56, the rim 30 of the bag will move toward the bottom surface 60 of the supporting block 50. As a result, the various flanges will bend or fold inwardly as indicated by the arrows 62 in FIGURE 2, toward the opposing inner surfaces of the bag 10. As previously indicated, it will be apparent that since the lower surfaces of the flanges are covered with the adhesive material 54, the flanges will be adhesively secured to the inner surfaces of the bag as the bag is moved downwardly along the block 50. More specifically, the quadrilateral flange 40 will be secured to the inner surface of wall 14, the quadrilateral flange 42 will be secured to the inner surface of wall 12, the triangular flange 46 will be secured to the inner surface of the portion 22 of end wall 18 and the inner surface of the triangular flange 44 will be secured to the portion 20 of the end wall 16. This is clearly shown in FIGURE 3 which indicates the condition of the bag provided with the collar 28 when the bag is removed from the block 50. It, therefore, will be apparent that the various flanges of the colar 28 have been folded inwardly from the position thereof shown in FIGURE 1 and secured at the upper end 26 of the bag to the inner surfaces of the adjacent walls of the bag and that the rim 30 extends outwardly from the various walls of the bag. It will be apparent from FIGURE 3, that with the various collar flanges secured to the inner sufaces of the adjacent wall portions of the bag in the manner illustrated and described, the bag mouth 26 is not distorted in any fashion. Moreover, it will be apparent that the flanges provide support and reinforcement for the bag 10 at the open end or mouth 26 thereof. The portions 20 and 22 at the upper ends of the opposing end walls 16 and 18 of the bag may be infolded along the lines indicated in FIGURE 1 to permit the upper end of the bag to be closed by swinging the collar against the bag as indicated by the arrow 64 in FIGURE 4. This, of course, is accomplished manually. It will be apparent that when the collar is swung against the bag in the described manner, the open mouth of the bag is closed because the various flanges of the collar are moved back to the position thereof illustarted in FIGURE 1, namely, each flange becomes planar with its associated rim portion. Consequently, if the bag 10 is filled with dirt or other refuse collected by the vacuum cleaner input conduit and blown into the bag 10, the dirt in the bag is inadvertently prevented from spilling from the bag by merely folding the collar against the bag as illustrated in FIGURE 4 whereby the various collar flanges will serve to close the open mouth of the bag which thereafter can be withdrawn from the vacuum cleaner without danger of spilling the dirt. Moreover, it will be noted that the flanges will swing into the bag, from the position thereof shown in FIGURE 1, in response to the suction created in the vacuum cleaner when the latter is operated.
