Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a flashlight, and more specifically,
This invention relates to a disposable flashlight with excellent preservability and moisture resistance that is ideal for use as an emergency equipment.

[Conventional technology]

For stand-alone emergency flashlights or flashlights stored in emergency bags, etc., periodic lighting tests are required to check the battery status and proper switch operation.

In other words, recently, sealed containers with excellent leakage prevention properties have been developed for dry batteries, which means that they are less likely to deteriorate due to natural discharge and can be stored for long periods of time. When assembled in a device that is prone to moisture, the amount of natural discharge due to discharge between pole pieces and lead pieces increases, accelerating the deterioration of battery function, as well as poor contact in the power supply circuit due to contact corrosion. This causes inconveniences such as not lighting up when used in an emergency after long-term storage.

Moreover, the disadvantages of such long-term storage are
This often occurs when stored in hot and humid places.

[The problem that the idea attempts to solve]

Therefore, emergency flashlights equipped with a moisture-proof container or a battery voltage check mechanism have been developed and provided as stationary lights for facilities, but these additional mechanisms make them relatively expensive.

Therefore, in ordinary homes and small shops, it is extremely troublesome and impractical to incur expensive equipment costs and store and manage emergency lights of this type, which are used very infrequently.

Therefore, the present invention was developed with the aim of providing a flashlight that is useful for use in emergency flashlights as well as outdoor flashlights, etc., and that can be stored for a long period of time at the lowest possible cost. It is something that

[Means to solve the problem]

According to the present invention, this object is achieved by sealing the open end of the container containing the battery with a light-emitting window section having a small light bulb, and disposing it between the electric circuit connecting the light bulb and the battery. The tip of the operating rod of the switch faces the front of the window, and the cap covering the window keeps the entire container, including the window, sealed, and the operating rod is held against its tendency to move. This can be achieved by configuring the switch to be kept in the open operating position.

[Effect]

According to the above configuration, the can-shaped flashlight housing housing the power battery and the light-emitting bulb is kept at low humidity because the inside of the can is sealed during storage.
Furthermore, this state can be maintained for a long period of time until the can is opened.

When in use, by removing the cap covering the light-emitting window, the light-emitting window is exposed, and
The operating rod, which had been placed in the switch open operating position by the cap, is no longer restricted by the cap, so it moves in the protruding direction due to the biasing force and closes the switch. It acts on This causes the light to emit light.

Therefore, by opening the can, the irradiated light from the window can be obtained.

〔Example〕

Next, illustrated embodiments of the present invention will be described in detail.

FIG. 1 is a longitudinal sectional side view of the main parts showing one embodiment of the present invention, in which an inter-electrode connection electrode plate 3 is arranged on the inner wall of the bottom 2 of a can body 1 made of metal etc., and connected in series or parallel. A plurality of connected dry batteries 4, 4 are housed in the can 1.

Reference numeral 5 denotes a small light bulb, in which a locking electrode tube 7 for receiving a base 6 is fitted into a central hole of a bowl-shaped reflector 8, and a transparent light bulb is integrally formed with a window glass portion 9 that covers the front surface of the reflector 8. Assembly cylinder 1 made of synthetic resin
0, an anode piece 13 having one end pressed into contact with the + electrode 12 of the light bulb 5 and the other end contacting one electrode of the batteries 4, 4..., and one end contacting the other electrode of the batteries 4, 4... A cathode piece 14 is placed in contact with the cathode piece 14, and the other end of the cathode piece 14 is made to face a switch structure portion to be described later.

That is, in the switch structure, the operating rod 15 is slidably supported between the receiving hole 16 of the bottom plate 11 and the insertion hole 17 of the window glass portion 9, and the intermediate step portion 18 of the rod 15 is slidably supported. One end of the contact piece 19 and a spring 20 are sandwiched between the opening end of the receiving hole 16 and the spring 20, and the spring 20 gives the rod 15 a tendency to move in the protruding direction. Electrical connection is established between one end of the cathode piece 14 facing the open end and the contact piece 19.

Furthermore, the free end 19' of this contact piece 19 is bent at a substantially right angle to the direction of movement of the contact piece 19, so as to face the contact area with the flange 7' of the locking electrode tube 7.

These batteries 4, 4... and the assembly cylinder 10
The can body 1 fitted with the can has a pull-top type cap body 21 on its open end face by pushing the tip of the operating rod 15 into the can against the expansion force of the spring 20. It is attached and sealed by rolling up the opening edge, and at the same time, the tip of the assembly tube 10 is pressed down with the rolling tightening edge 21'.
In addition to preventing the cylinder 10 and the batteries 4, 4... from falling out, the tip of the operating rod 15 is pushed into the can against the urging force, and in this state, it is integrated with the rod 10. The free end 19' of the contact electrode 19, which moves in the opposite direction, is in a position away from the flange 7' of the anode piece 7, and the switch is in an open state.

Therefore, the dry batteries 4, 4, etc. stored under the seal of the cap body 21 have very little natural discharge due to moisture intrusion into the can when the switch is opened and the small light bulb 5 is turned off. There is very little discharge and it remains stable for a long time.

Therefore, the cap body 21 of the can body 1 stored in such a state is pulled up by removing its lifting piece 22, and the can is opened by leaving the rolled-up edge 21' as in the case of this type of pull-top type. As the portion 9 is exposed, the operating rod 15, which has been pushed by the cap body 21 and has been in the open position, moves to the left in FIG. 1 due to the biasing force. This also causes the contact piece 19 to move and its free end 19'
The protruding position of the contact piece 19 and the operating rod 18 (the position shown by the chain line in the figure) is restricted at the position where the contact piece 19 and the operating rod 18 come into contact with the flange edge.

The connection between the electrode tube 7 and the contact piece 19 is such that the contact piece 19 is electrically connected to the cathode piece 14 via the spring 20, so that the switch is closed and the small light bulb 5 is lit.

Therefore, search light can be automatically irradiated from the light emitting window exposed when the cap body 21 is removed and the can is opened.

This lighting state can be interrupted by placing the opened can body 1 face down on a table surface or the like and pushing the operating rod 15 back into the can.
continues until it is exhausted.

In the flashlight of the present invention, the shape of the can body 1 can be various shapes such as a pencil shape in addition to the various canned shapes that have been conventionally provided, and the material of the can body 1 can be metal, plastic, etc. It is possible to use containers with excellent water-tight sealing properties, and in particular transparent containers made of plastics, glass, etc. can be used to achieve unique commercial effects.

Furthermore, as for the power supply battery to be accommodated, in addition to the existing type dry battery 4, various primary batteries such as a special dry battery that is directly packed into the can 1, a lithium battery, and an air battery can be used.

In addition to the pull-top type, the cap body 21 is also of the pull-top type.
A fitting type cap with a flange made of plastic or rubber material may be used to remove it during use, and a fitting type cap may be used in conjunction with this for use when the lamp is interrupted after the light is turned on. It is convenient to use as a fitting cap.

[Effect of idea]

As described above, according to the flashlight of the present invention, the light emitting part consisting of a battery and a small light bulb is housed and sealed inside the can, and the can can be opened by removing the cap body when in use.
Since the built-in switch is closed to turn on the light, it is possible to keep the humidity inside the can low during sealed storage through manufacturing control, preventing natural discharge of the stored battery, and protecting the switch part, electrode pieces, etc. Since it is possible to prevent rust from forming on contact surfaces, long-term storage of about 3 to 5 years is possible.
Excellent waterproofness until use by opening the can,
The flashlight of the present invention is extremely effective when used as an emergency flashlight or an outdoor flashlight.
