, l -This invention relates to new and useful'improvements in cigarette lighters and the primary object of the present invention is to provide a cigarette lighter including novel and improved means for receiving lighter fluid so that the packing in the lighter may be saturated with the fluid in a convenient manner.

Another important object of the present invention is to provide a cigarette lighter filler unit including a valve normally urged to its closed position for restricting the flow of fluid from the lighter and which valve is quickly and readily urged to an open position by the discharge nipple of a container of lighter fluid pressed thereagainst.

A further object ofthe present invention is to provide a filler unit attachment for cigarette or pipe lighters including a fluid receiving opening countersunk at its entrance to reduce to a minimum the fluid wasted during the filling of a lighter.

A still further aim of the present invention is to provide a cigarette lighter filler unit that is simple and practical in construction, strong and reliable in use, small and compact in structure, neat and attractive in appearance, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawingsforming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a fragmentary view, partly in elevation and partly in section, of a lighter and showing the present invention in section applied thereto;

Figure 2 is a bottom plan view of a lighter the present unit applied thereto; and

Figure 3 is a group side elevational view of the present invention removed from a lighter.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral I 9 represents a lighter or lighter casing of any suitable type having a wall I2 in which there is provided an internally threaded filling opening II.

The opening it normally receives a closure plug (not shown) that is completely removed in order to place a lighter fluid into the cotton or packing removal and replacing tithe-closure plug and often results in'a los'sage of the plug since the same must be held in one hand while a fluid is injected through the opening l4. Such a filling operation also requires considerable time and frequently the use of a tool or a coin for turning the closure plug.

It is therefore the principal object of the present invention to provide an attachment for the lighter or a replacement for the closure plug that will eliminate the aforementioned dimculties.

To accomplish the desired results, there is provided a plug designated generally by the numeral [8 and which is constructed of any suitable material, such as plastic, cork or metal. This plug 18 includes an externally threaded head portion 20 that receivably engages the opening I4 and a tubular, perforated or slotted, shank portion 22 that extends inwardly of the wall l2.

The head portion 20 is provided with an axial filling opening 24 the ends 26 and 28 of which are counter-sunk to provide an entrance and valve seat respectively.

A rivet of holding member 33 is fixed to the inner end of the shank portion 22 and forms an abutment for one end of a coil spring 32. The freeend of the spring 32 is tapered, as at 34, and urges a ball valve 36 to its closed position in the seat 28.

Diametrically opposed recesses or kerfs 38 are provided in the outer face of the head portion 20 to receive'a suitable tool or coin for turning the plug i8 during the removal or replacement thereof.-

In practical use of the present invention, the

lighter i0 is held so that the wall I2 is above v the valve 38. The nipple end or discharge tit of a container of lighter fluid is then pressed against the valve 36 to urge the same to .an open position.

Should any of the fluid discharged from the container fail to enter the shank 22, the fluid will then be retained in the entrance 26 until the fluid evaporates or passes into the shank portion 22.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully compreceived in said opening, a spring mounted in said I shank portion and having a tapered end bearing against and urging the valve to' its closed position, said spring being of a diameter substantially equal to the internal diameter of the shank portion, and an abutment fixed to and located within said shank portion for said spring. said valve being located relatively close to the outer face of said head portion to permit the discharge nipple 20 of a container of lighter fluid to. urge the valve to its opening position during filling of the lighter 4 with a fluid, said abutment comprising a pin extending diametrically through said shank portion and having flattened ends disposed exteriorly of said shank portion.
