The present invention relates to a lighter, and in particular, to a lighter with an upper cover.
Currently, lighters with upper covers on market have their upper covers connected to brackets of combustion devices, which disadvantageously make the structures complicated and the connections between the upper covers and the brackets vulnerable to abrasion. Besides, it is relatively difficult to manufacture and assemble the lighter with such structure, which may lead to high rate of unqualified products, and furthermore, if there is any failure in the connection, it would be much difficult to fix it. In addition to such lighters, there is another type of lighter which has its upper cover integrated with the lighter housing. Disadvantages of such structure are that the structure is complicated, the proportion of unqualified products is high due to the application of point-welding process to the connection, and the overall aesthetic effect of the lighter is damaged by possible concave welding spots caused by high temperature welding.
One objective of the present invention is to provide a lighter with an upper cover to overcome the above defects of the prior art and have simple structure, easy process of assembly and low cost.
In accordance with the present invention, the lighter comprises a lighter housing, a gas container for storing liquid inflammable gas, a combustion device connected to said gas container, and an igniter for igniting inflammable gas in said combustion device, characterized in that said housing includes an upper cover and a case, wherein one side of said upper cover includes a protuberance forming a small hole thereon; a connector disposed below said protuberance of said upper cover for connecting said upper cover and said case, wherein said connector includes a recess portion coupling with said protuberance and having transverse holes on both sides of the recess portion; and a bolt for rotationally connecting said protuberance and the recess portion; wherein said case has at its edge port a longitudinal groove being connected to said connector and having an opening at the edge port of the groove to couple with the protuberance of said upper cover. Furthermore, the connector has a thickness from 1.0 mm to 11 mm.
The lighter with an upper cover according to the present invention is simple in structure and easy in assembly. Since there is provided with a connector, the variation to the structure of the upper cover and the case of the lighter may achieve simple and rational assembly of the case with low cost and simple manufacture.
Wherein: 1—lighter housing; 11—upper cover; 110—protuberance; 111—small hole; 12—case; 121—longitudinal groove; 122—opening; 2—gas container; 3—combustion device; 4—igniter; 5—connector; 51—transverse hole; 52—recess portion; 6—bolt.
The present invention now will be described in detail with reference to the embodiments and drawings.

During the process of assembly, the protuberance 110 is inserted into the recess portion 52, and the bolt 6 passes through the transverse holes 51 and the small hole 111 to connect the connector 5 and the protuberance 110. At the edge of the case 12, there are two longitudinal grooves 121 corresponding to both sides of the connectors 5 (refer to
The connector has a thickness from 1.0 mm to 11 mm, which facilitate to couple the connector 5 with the upper cover 11 and case 12.
In order to open or close the upper cover 11 of the housing 1 without hitch, an opening 122 is formed at the edge port of the longitudinal groove 121 of the case 12 so as to moveably connect the protuberance 110 and case 12 when the upper cover 11 fits in the case 12.
Though the present invention has been described in details with reference to the drawings and embodiment, it should be understood by those skilled in the art that the aforementioned embodiments are only for description of the invention and not intended to limit to the present invention. A various of modifications or variations could be made according to the invention and will fall into the protective scope of the present invention.
