Disclosed is a multi-purpose lighter mainly including a case and an igniting means associated with the case to form a union body of the lighter. The case has an integrally formed separating wall which upward projects from a bottom center of the case and defines an elongated inner space with an expanded and internally threaded opening near the bottom of the case. A long pin having one pointed end and an expanded and externally threaded head opposite to the pointed end is screwed into the threaded opening of the separating wall for serving as a toothpick. The expanded head of the long pin has a projected handle for a user to hold to easily screw the long pin into the separating wall. The handle is formed with a connecting hole for a key ring with several keys to hook thereto. A bottle-opener is fixedly attached to the case by ultrasonic or high-frequency wave. The multipurpose lighter is more useful and heavier to draw the user's attention to more carefully keep it without carelessly dropping it here and there.

BACKGROUND OF THE INVENTION 
The present invention relates to a lighter, and more particularly to a 
multi-purpose lighter which may also be conveniently used to contain a 
toothpick and hold a key ring. 
There are many disposable and cheap lighters available in the market that 
need not to refill gas or replace the flint and are therefore widely 
welcomed. They are often used by general stores and restaurants as 
giveaway to promote businesses. Such disposable lighters are very light in 
weight and small in volume, they are usually arbitrarily placed, discarded 
or carelessly dropped here and there. 
Bottle-opener and toothpick are something that are usually separately 
positioned but both are usually needed when taking a meal. It would be 
more than convenient if these items are associated with a lighter and form 
a union body. 
Such a lighter with toothpick and bottle-opener associated therewith to 
provide multiple functions is particularly convenient on picnic and other 
outdoor activities. Moreover, the multi-purpose lighter is heavier than 
the conventional disposable lighter, it will draw the user's attention to 
more carefully keep it along with the user without being easily dropped 
here and there. 
SUMMARY OF THE INVENTION 
It is therefore a primary object of the present invention to provide a 
multipurpose lighter which mainly includes a case, and an igniting means. 
The igniting means is associated with the case to form a union body of the 
lighter. The case has an integrally formed separating wall upward 
projecting from a bottom center of the case. The separating wall defines 
an elongated inner space which has an expanded and internally threaded 
opening near the bottom of the case. A long pin having one pointed end and 
an externally threaded expanded head opposite to the pointed end is 
screwed into the elongated inner space of the separating wall for serving 
as a toothpick. The threaded head of the long pin has a projected handle 
for a user to hold to easily screw the long pin into the separating wall. 
The handle is formed with a connecting hole for a key ring with several 
keys to hook thereto. Therefore, the present invention allows a user to 
carry a lighter, a personal toothpick and keys at the same time and draw 
the user's attention to more carefully keep the lighter without carelessly 
dropping it here and there. 
Another object of the present invention is to provide a multi-purpose 
lighter having a bottle-opener fixedly attached to an arcuate surface of 
the case by heat sealing via ultrasonic wave or high-frequency wave. The 
bottle-opener attached to the lighter provides more convenience to the 
user when taking a meal outdoors, such as on a picnic.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
Please refer to FIGS. 1 and 2 which are assembled and exploded 
perspectives, respectively, of a lighter according to the present 
invention in an upside-down position. As shown, the lighter includes a 
case 1 for containing liquid gas therein and an igniting means 2 fixedly 
associated with the case 1 to form a union body of the lighter. The case 1 
has an integrally formed separating wall 11 upward extending from a bottom 
center of the case 1. An inner space defined by the case 1 is divided into 
two mutually communicable rooms by the separating wall 11. 
As shown in FIG. 2 and FIG. 3 which is a side sectional view of the present 
invention, the separating wall 11 in the case 1 defines an elongated inner 
space 12 having an expanded opening 121 near a bottom of the case 1. The 
opening 121 is provided around its inner periphery with threads 122. A 
plastic long pin 13 having a pointed end and an externally threaded head 
131 at the other end opposite to the pointed end is removably received in 
the elongated inner space 12. 
Threads 132 provided around the head 131 engage with the threads 122 of the 
opening 121, allowing the long pin 13 to be screwed into the elongated 
inner space 12. The long pin 13 may conveniently serve as a toothpick for 
personal use. 
As shown in the drawings, a handle 133 having a connecting hole 134 
projects from an outer surface of the head 131 of the long pin 13. A user 
may hold the handle 133 to easily screw the long pin 13 into the elongated 
inner space 12 via the opening 121. As shown in FIG. 4, a key ring 3 may 
be hooked to the connecting hole 134 of the handle 133 for holding several 
keys along with the lighter. The key ring 3 and keys increase the weight 
and volume of the lighter, preventing the user from neglecting the 
existence of the lighter and arbitrarily dropping the lighter. The lighter 
with key ring and personal toothpick attached thereto is more useful and 
convenient for use. 
FIG. 5 illustrates a preferred embodiment of the present invention. In this 
embodiment, a bottle-opener 4 is fixedly attached to one arcuate surface 
of the case 1 by means of heat sealing via ultrasonic wave or 
high-frequency wave. A lighter with bottle-opener 4 is particularly 
convenient for camper or picnicker. An embrassing situation that no 
bottle-opener is available in camping or on picnic can be avoided. 
The multipurpose lighter of the present invention has very simple structure 
while it can be used to hold keys, toothpick, and bottle-opener at the 
same time. These added value of the present invention helps people to more 
carefully keep their lighters without arbitrarily discarding or dropping 
them here and there.
