Description

[Detailed Description of the Invention] The present invention relates to a lighter, and particularly to a lighter with excellent waterproofness.

Conventional lighters, especially the lighter case itself,
The lighter case includes a lid that closes the opening of the lighter case body, and a unit that is housed in a space formed by the lighter case body and the lid and has a fuel tank and an ignition mechanism. In lighters, the lighter case body and the lid are generally made of metal, and the two are integrated like a hinge so that the openings of the two abut against each other when the lid is closed. The reality is that due to its structure, it has poor waterproof properties. Also, if it is dropped due to careless handling, it may cause local deformation due to impact.
In particular, the hinge portion tends to loosen, further reducing waterproofness. Therefore, if the conventional lighter of the above type is accidentally immersed in water or exposed to rain, ignition is inhibited and the lighter cannot function as a lighter.

Therefore, an object of the present invention is to provide a lighter that is of the above type but has excellent waterproof properties.

According to the present invention, a lighter case body, a lid body that closes an opening of the lighter case body,
In the lighter, which is housed in the space formed by the lighter case body and the lid and is equipped with a fuel tank and a unit having an ignition mechanism, the entire edge of the open opening of the lighter case body and a watertight elastic gasket is fitted to the entire edge of the open opening of the lid,
An upper cover that also serves as a windshield is fixed to the unit, and an opening formed as a vent in the upper cover is provided with a female threaded portion, while the lid has a
A tightening bolt is provided which is screwed into the female threaded portion via an elastic packing and brings the elastic packing at the open opening of the lid body into abutment with the elastic packing at the open opening of the lighter case body to provide waterproofness. By the writer, which is characterized by
The above objectives can be achieved.

Next, an example of an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The lighter 10 according to this embodiment first includes a lighter case 11 and a lid 12 that is separate from the lighter case 11. These lighter case 11 and lid body 12 are each obtained by deep-drawing a metal plate, and each has an open mouth, and the entire edge of each open mouth is covered with rubber, synthetic rubber, etc. A water-tight elastic packing 14 is fitted with a U-shaped cross section as shown in FIG. In the closed state, the elastic gasket 14 attached to the opening of the lighter case body 11 and the lid body 12
The elastic packing 14 attached to the open opening of the lighter 10 is brought into close contact with the lighter 10 to keep the inside of the lighter 10 not only watertight but also airtight, which will be explained below with reference to FIG. .

As shown in FIG. 2, in the space formed by the lighter case 11 and the lid 12,
A unit 17 having a fuel tank 15 and an ignition mechanism 16 is accommodated. An upper cover 18 that also serves as a windshield is fixed to this unit 17. A flint (not shown) is attached to the upper cover 18 by removing the lid 12 and rotating the file wheel 16A.
It has an opening that becomes a tinder when it is ignited by rubbing it, and this opening is equipped with a female threaded portion 18A.

On the other hand, a tightening bolt 20 is attached to the lid body 12. This tightening bolt has a male threaded part 20A,
A shaft portion 20B that is loosely fitted into a through hole formed in the lid body 12 and is integral with the male threaded portion 20A, and an operation that allows the male threaded portion 20B that is screwed to the shaft portion 20B to be rotatable. 20C. A ring-shaped elastic packing 21 is attached to the shaft portion 20B.
is installed.

With the lid 12 removed from the lighter case body 11, if the user of the lighter 10 aligns the open mouth of the lighter case 11 with the open mouth of the lid 12, the above-mentioned upper part cover 18
The opening formed in and the above tightening bolt 20
The male threaded portion 20A is aligned with the male threaded portion 20A, so if you turn the operating portion 20C of the tightening bolt 20 to the right, the male threaded portion 20A will align with the female threaded portion formed in the opening of the upper cover 18. 18A, the lid body 12 is combined with the unit 17 and eventually the lighter case 11, and the lighter 10 is closed. At this time, the elastic gaskets 14, 14 closely abut each other to provide waterproofness between the lighter case body 11 and the lid 12, and the through hole formed in the lid 12 is also covered by the elastic gasket 21. kept waterproof.

As mentioned above, when the lighter according to the present invention is closed, it is not only waterproof but also airtight. Therefore, when the lighter's fuel is volatile oil, the lighter according to the present invention has the additional advantage of being able to prevent its volatilization while being carried and achieve effective use of the fuel.
