Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disposable gas lighter, and more particularly to a disposable gas lighter equipped with an opening/closing lid for extinguishing fires and preventing the adhesion of dust.

A disposable gas lighter consisting of a plastic gas tank containing liquefied gas, a valve above it, and an ignition mechanism consisting of a file, a flint stone, and a lever for opening the valve placed near the valve. is widespread. This type of disposable gas lighter is extremely cheap, lightweight, and convenient to carry, so it is widely used in place of matches, but safety considerations are necessary because the ignition mechanism is exposed. That is, if the valve does not close completely when extinguishing a fire, a very small flame (so-called firefly) remains, which may ignite the garbage in the pocket and burn the pocket. Therefore, a means to prevent this is required. One way to solve this firefly problem is to improve the accuracy of the valve opening/closing mechanism so that the valve closes completely, but this increases costs and is not a practical idea.

Therefore, a firefly fire solution that is inexpensive to produce is desired. On the other hand, since this type of lighter is often carried in a pocket, it must be constructed in such a way that it will not accidentally ignite in the pocket. The species writer is
The gas ejected from the valve is ignited by two actions: rotating the file when igniting, and opening the valve with the thumb. Under normal conditions, it is rare for a lighter in your pocket to accidentally ignite due to these two actions, but if the lighter collides with an object, such as during intense exercise, it will ignite. It is possible. The present applicant has provided a fire extinguishing lid above the valve with the aim of providing a new disposable gas lighter that simultaneously solves the problem of fireflies caused by incomplete extinguishing and the problem of careless ignition. He invented a new lighter and has already applied for a patent.

(Japanese Unexamined Patent Publication No. 52-154481) The lighter of the present invention has a fire extinguishing lid that can be opened and closed above the valve, and the lid is opened and closed by an operation independent of the ignition operation. In other words, when igniting, first open the fire extinguishing lid,
Next, the file is rotated and the valve opening lever is pressed down to ignite the fire, and when extinguishing the fire, the fire extinguishing lid is closed after releasing the lever. According to the above-mentioned lighter according to the previously filed invention, it is possible to extinguish fireflies and prevent accidental ignition, but the operation at the time of ignition becomes complicated, and improvements in practical use are desired.

Therefore, in order to make the above-mentioned gas lighter with a lid easier to use in practice, a gas lighter has been proposed in which the opening movement of the lid can be performed at the same time as the rotation of the file. (Utility Model Publication No. 51-2198@) In addition to providing a lid, a finger hook for opening the lid was formed in a part of the lid so that the lid could be opened by the movement of the fingers used to rotate the file. It is characterized by this. As a result, the lid opens at the same time as the file rotates during ignition, and no special action is required to open the lid, which simplifies the ignition operation in practice. However, this gas lighter has a lid opening operation. Since the lever for opening the valve is now operated more frequently, there is a problem that when the lid is opened inadvertently, the valve also opens, and if this is accompanied by rotation of the file, a fire may ignite in the pocket. There is a possibility that this may occur, and further improvements are desired from the standpoint of safety measures. By the way.

The present invention separates the opening/closing of the lid and the lever for opening the valve,
Prevent the lever from being operated when the lid is opened or closed.
The purpose is to provide a gas lighter with even greater safety.

The gas lighter of the present invention is configured to open and close the lid and rotate the file at the same time, and to open and close the valve separately, thereby simplifying the ignition operation and preventing accidental ignition.

This extremely effectively prevents accidental ignition in the pocket. In addition, the opening/closing lid effectively extinguishes fireflies and effectively prevents trash in the pocket from being ignited. That is, the gas lighter according to the present invention is a disposable gas lighter in which a valve is provided at the top of a plastic gas tank, and an ignition mechanism consisting of a file and a lever for opening the valve is arranged near the valve. The valve opening lever is provided with a lid that can be opened and closed independently, and the rotation trajectory of the lid and the rotation trajectory of the valve opening lever are overlapped so that the valve opening lever is not operated by opening and closing the lid. A means is provided to hold the lid in the closed position, and a means is provided to prevent the ignition from occurring. A finger hook for opening the lid is formed in a part of the lid so that the lid can be opened against the force of the holding means by the movement of the fingers used for rotating the file, and Immediately after the lid is opened, the valve opening lever is directly pressed down by the movement of the finger moving downward, and while the valve opening lever is being pressed down, a part of the lid opening finger hook part of the lid is pressed down. The finger hook for opening the lid is held from above the pressing part of the lever for opening the valve so that the lid is kept in the open state by being caught by the finger, and the lid is closed after releasing the finger from the lever for opening the valve. It is characterized in that it is provided so as to move toward the side of the pressing part.

Therefore, when the lid is opened alone, the valve opening lever is not operated and gas does not leak, and even if the valve opening lever is pressed and the valve opens, the lid will not open as a result, and both will naturally open. It is possible to prevent these operations from occurring simultaneously with an extremely high probability.

In addition, the finger hook used to open and close the lid is designed so that when you press the valve opening lever, your finger catches and opens the lid, and the lid closes only after you release your finger from the valve opening lever.
When the lever is pressed down, the lever is placed in a position where it hangs on your finger (i.e., it moves from above the pressing part of the lever towards the side of the pressing part), so when the lighter is ignited, the lid opens. The lid can be closed at the same time as the fire is extinguished. It should be noted that among metal gas lighters that are not conventionally disposable, those using lids are well known.

However, this lid is usually linked to a valve opening lever, so opening and closing of the lid and opening and closing of the valve are performed in one operation. With this, if the lid is accidentally opened in a pocket, the valve will also open, and if the file rotates, there is a risk of ignition or explosion. In this regard, in the lighter of the present invention, the valve opening lever and the lid are independent of each other, so there is no such fear. Embodiments of the present invention will be described in detail below with reference to the drawings.

1 to 3 show a first embodiment of the present invention. The gas lighter of this embodiment has a rotatable lid on the upper part of the gas lighter main body, and as shown in Fig. The lid part 4 of the lid body 3 is placed over a certain windshield 2, and a finger (with a file rotated) is placed on a part of the lid body 3 at the time of ignition.
A finger hook 5 is formed so that the lid 4 can be opened by pushing down with the outside of the right thumb. This lid body 3 is made of a file stone (not shown) with a shaft 6
When the finger hook part 5 is pushed downward with a finger,
The cover 4 is opened by rotating clockwise around its axis. (See Figures 2 and 3) The lid part 4 and the finger hook part 5 are integrally connected, and an opening part 8 is provided between them to expose the upper part of the horizontal wheel 7 made of sandstone.

The finger hook portion 5 is located at the rear of the horizontal wheel 7 (on the valve opening lever 9 side) and above the valve opening lever 9.
As a result, when the horizontal wheel 7 of the file stone is rotated with the finger 10, the finger 10 hangs on the finger hook 5 at the same time as the horizontal wheel 7 rotates.
By pushing this downward, the lid body 3 is rotated clockwise from the closed state shown in FIG. 2 to the open state shown in FIG. 3. This finger 10 uses its force to push down the valve opening lever 9, so that the valve opens and ignition is performed like a conventional gas lighter. In this way, according to this embodiment, the lid 3 opens at the same time as the file rotates, that is, with the same action as rotating the file, so no special action is required to open the lid, making it practical. It is advantageous.

In addition, in the above embodiment, as shown in FIGS. 3 and 4, on the back side of the lid part 4 of the lid body 3, there is a hook that is engaged with the overhanging part 2a (shown in cross section only in FIG. 4) at the upper end of the windshield 2. Snap protrusion 4
a is formed, and when the lid is closed, this protrusion 4a is elastically snapped onto the protruding portion 2a of the windshield 2 to hold the lid portion 4 in the closed position.

When opening the lid, the finger hook 5 is pushed by the finger 10, the lid body 3 rotates against the force of the snap fastening, and the lid opens. Therefore, in this embodiment, when closing the lid, after releasing the finger 10 from the finger hook part 5, the lid part 4 is pressed with the finger (even with the same finger 10,
Press it onto the windshield 2 with your other fingers (you can also use your other fingers) and snap it to close it. As explained above, the gas lighter with a lid of the present invention has a lid for extinguishing fireflies and preventing the intrusion of dust.
Simultaneously with the rotation of the file stone during ignition (with the same finger movement)
Since it is easy to open, it is practical and convenient.

Further, since the lid and the valve opening lever are constructed independently of each other, there is a very small possibility that both the lid and the valve will open inside the pocket, which is excellent in terms of safety.
