Abstract

PROBLEM TO BE SOLVED: To provide a fixing means for a hinge member, which is useful especially for a lighter case material in which a welding of metal hinge member is impossible to a resin of a portable lighter case, in which a fuel tank and an ignition part are integrated with each other. SOLUTION: The lighter case comprises an upper case and a lower case, a fuel tank and an ignition part are integrally provided in the lower case. Slip- stop protrusions are formed by partly louvering edges of both side metal sheet members of the upper and the lower sheet members, which are connected rotatably by a hinge. Respective sheet members are inserted in hinge-insertion grooves formed respectively in the upper and lower cases, in which the slip-stop protrusions are fit in the grooves formed in the inside wall to ensure a slip-stop function and at the same time both the upper and lower cases are connected to each other.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighter case for storing and carrying a lighter main body in which a fuel tank and an ignition section are integrated.

[0002]

2. Description of the Related Art Conventionally, a fuel oil-filled portable lighter has a state in which a main body in which a fuel tank and an ignition section are integrated is housed in a metal case divided into upper and lower parts. However, although the durability is ensured by using a metal case, it is not easy to apply a desired design to the case surface or the case itself, or to form a complicated surface shape.

In addition, if a non-metallic material such as plastic is used,
Particularly, in a lighter case, polycarbonate is used because heat resistance is required. In this case, it is impossible to weld the hinge to the case. Therefore, it is necessary to fix the hinge in the case with an adhesive. However, when the adhesive is used, the bonded portion is easily deteriorated, causing cracks and causing a problem in durability.

SUMMARY OF THE INVENTION The present invention relates to a lighter case for storing and carrying a lighter body in which a fuel tank and an ignition section are integrated, and is made of a metal such as a resin material such as plastic. It is an object of the present invention to provide a particularly advantageous hinge member fixing means for a lighter case material which cannot be fixed to the hinge member by welding.

[0005]

Means for Solving the Problems To solve the above problems, the present invention employs an upper case and a lower case, in which a lighter body in which a fuel tank and an ignition section are integrated is housed in a lower case. In a lighter case, a hinge in which an upper plate-like member and a lower plate-like member having retaining projections formed by cutting and bending a part of both side edges made of metal are rotatably connected by a hinge is provided inside the upper case and the lower case. The upper case and the lower case are rotatably connected to each other while being inserted into the hinge insertion grooves formed therein and engaging the retaining projections with the inner wall of the groove to prevent the removal.

Further, the upper case and the lower case are formed such that upper end portions on the guide groove side are inclined surfaces, and a hinge receiving portion for receiving a hinge hinge portion is provided at a central portion of the inclined surfaces.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. With reference to FIGS. 1 to 6, (1) is an upper case, and (2) is a lower case, which is formed of a resin material such as plastic and has a rectangular cross section with one end closed. On the inner wall of the lower case (2),
A ridge designed to prevent and secure rattling of the lighter body when the lighter body is stored inside the case
(5) are formed two on each of the opposing inner wall surfaces,
An insertion groove for receiving the hinge (3) at one end of the inner wall
(6) is formed. An inclined surface (8) is provided at one end of the open end of the lower case (2) to prevent mutual interference when the upper and lower cases are rotated, and a hinge (3) is provided at the center of the inclined surface. Hinge receiving part (7) for receiving part
Are formed. The upper case is the same as the lower case (2).
Although (1) also has an inclined surface (11) and a hinge receiving portion (10), no projection is formed because it is not necessary to fix the lighter body in the upper case (1). The present invention
It is particularly effective for a lighter case material in which it is impossible to weld a resin material such as plastic or a metal hinge member such as rubber or wood. However, it enables fixation to a weldable lighter case material such as metal without welding. By fixing without welding, welding marks are not formed on the surface of the lighter case, and the lighter case can be beautifully finished.

[0008] (3) is a hinge for connecting the upper case (1) and the lower case (2), and connects the upper plate member (3a) with the lower plate member (3b) and the upper and lower plate members. (3c). Upper plate-shaped member (3a) The tip is the lighter body
(12) It is bent in a U-shape so as to receive the lid engaging projection on the upper surface. On both sides near the base of the U-shaped portion, retaining protrusions (4) are formed by cutting and bending a part of the upper plate-like member (3a). The lower plate-like member (3b) is also located near the center of both side edges in the same manner as the upper plate-like member (3a).
A retaining projection (4) formed by cutting and bending a part of (3b) is formed. Also, near the tip of the lower plate-shaped member (3b),
It is curved in the direction opposite to the projecting direction of (4). The upper plate-like member (3a) and the lower plate-like member (3b) are connected by connecting pins (3c).
Are connected rotatably.

Next, the upper case (1) and the lower case (2) are hinged.
The connection method in (3) will be described step by step. FIG.
Shows the respective relationships when the upper case (1) and the lower case (2) are connected by the hinge (3). The width of the guide groove (9) provided in the upper case (1) is slightly larger than the thickness of the upper plate-like member (3a), and the depth of the guide groove (9) is the The distance from the deepest part to the deepest part is formed to have a dimension that is substantially the same as the width of the upper plate member (3a). Insertion groove to fix upper plate member (3a) in upper case (1)
Push in the upper plate-like member (3a) along (9). As described above, since the retaining protrusion (4) is formed on the upper plate-like member (3a) toward the hinge portion, the urging force acts on the width direction of the insertion groove (9) to prevent rattling in the width direction. At the same time, the upper plate-shaped member (3a) is securely and easily fixed by playing a role of a return. Since the width of the U-shaped portion of the upper plate-shaped member (3a) is narrowed as described above, the upper case (1)
Fits without interfering with the inner wall of

As for the insertion groove (6) formed in the lower case (2), similarly to the upper case (1), the distance from the deepest part of the opposing groove to the deepest part is the width of the lower plate-like member (3b). It is formed to have dimensions that are substantially the same as. Also, the width of the insertion groove (6) is formed to be slightly larger than the thickness of the lower plate-like member (3b) similarly to the upper case (1). When fixing the lower plate-like member (3b) in the lower case (2), the lower plate-like member (3b) is pushed along the insertion groove (6) as in the case of the upper case. At this time, rattling is prevented by the action of the curved portion near the tip of the lower plate member (3b) and the retaining projection (4), and
The lower case (2) is formed by the return action of the retaining projection (4).
It is securely and easily fixed inside. The open ends of the upper case (1) and the lower case (2) are provided with hinge receiving portions (7) and (10) for receiving the hinge portion of the hinge (3). Slope surfaces (8) and (11) are formed around (10) so that the hinge and upper and lower cases do not interfere with each other even when the upper case (1) is rotated by the hinge (3). .

According to the present invention, a lighter case for storing and carrying a lighter body in which a fuel tank and an ignition section are integrated can be formed of a resin material such as plastic. It is possible to easily design the surface of the case or to make the case itself into a desired shape.
