3 Claims. (01. 210-170) My present invention relates to filters and latter in use, it is inverted and inserted in the more'particularly to small filtering'units adapted basin so that its shoulders rest upon conforming to be used in conjunction with containers'and shoulders l2 on the latter. The thrust head 9 packages of liquids to prevent impurities from thereby engages the'bottom of "the basinand unissuing when the contents are emptied or drawn seats the valve, as shown in Fig. l, whereafter 5 off, and it has for its object to provide a simple, the contents of the container replenish the basin inexpensive and efficient unit of this kind. The in a familiar manner. The fiow is through the improvements relate in part to a provision for enlarged aperture l3 through which the valve the adaptation of the unit to the container and stem passes.
10 to the provision of renewable filtering media that In the practice of my invention, I provide a 10 can be discarded when fouled and readily refiltering unit that is insertable in and removable placed at small expense. To these and other from the neck of the container without in any ends, the invention resides in certain improveway interfering with the above arrangements or ments and combinations of parts, all as will be disturbing their functions, and in the description 5 hereinafter more fully described, the novel feathereof I will for convenience use top and tures being pointed out in the claims at the end bottom as those terms apply in the illustrations. of this specification. I provide a cylindrical hollow body element M In the drawing: having foraminous side walls, open at one end,

This is soldered or otherwise se- 20 fitted with a filtering unit constructed in accordcured 'at its top end within a rigidly relatively ance with and illustrating one embodiment of my thick encircling band I6. It is similarly proinvention; vided at its lower end with a like band l'l so that With respect to its position in Fig. 1, Fig. 2 is the general effect is that of a tube with an intera bottom end view of the unit; mediate portion of its side walls perforated and Fig. 3 is a corresponding top end view of the itskupper end interiorly closed by a perforated unit; dis

It will be neck. Thereupon, the cap II is applied, pressing obvious that the spring Ill will normally hold the the flange to its seat and holding the unit firmly valve closed and hence maintain the container in place within the body of oil. sealed. When, however, it is desired to put the In operation, all the oil that reaches the outlet 55 l3 to the interior of the basin must pass through either the lateral filter or the end filter and in passing through both until the level gets very low sufiicient flow of filtered oil is maintained. Under the circumstances chosen in this embodiment, for instance, an expensive filtering medium would not be practicable and yet oil as supplied for burners almost inevitably contains solid impurities such as scale from the interior of the package and the burner jets are so fine that these, if permitted to reach them, cause a great deal of trouble. With my simple device, such trouble is eliminated while the cost of the filter renewable parts is negligible 2.

' a foraminous bottom end Wall, an intermediate portion only of the lateral wall being also foraminous, a renewable band of fibrous material exteriorly covering the last mentioned foraminous portion and a renewable disk of fibrous material exteriorly covering the foraminous bottom.
3. The combination with a dispensing container having a neck and a mouth, of a detachable tubular filtering element extending into the neck in spaced relationship thereto embodying an outwardly flanged outer end resting against the mouth, a foraminous bottom end wall, an intermediate portion only of the lateral Wall being also foraminous, a renewable band of fibrous textile material exteriorly covering the last mentioned foraminous portion, a renewable disk of fibrous material exteriorly covering the foraminous bottom, and a detachable cap on the neck sealing the flange of the filtering element against the mouth.
