Definitions

• the present invention relates to a pocket lighter comprising a manually seizable handle as constituting a fuel tank.
• the invention particularly relates to lighters of the type comprising a longish fuel tank extending downwardly from the lighter top as comprising the lighter burner and ingniter unit.
• the bottom of the handle in general, is configured flat so that the lighter can be left standing alone, although this is no functional requirement.
• Pocket lighters exist as refillable lighters and lighters which are disposable and purchasable at a relatively low price, and the invention is mainly concerned with the latter type of lighters.
• the invention aims at an improvement of the housing of the lighter, i.e. an improvement of the handle as normally constituting the fuel tank.
• the end or bottom of the handle of the lighter comprises a hook like protrusion, which projects downwardly adjacent one side of the bottom surface and partially inwardly over the remaining bottom surface.
• the lowermost exposed surface portion of this projection will be of an area smaller than the cross sectional area of the lighter handle, whereby it is usable in a highly relevant manner as a pipe stopper.
• the hook like projection will be usable for another typical "pocket tool purpose", viz. as a crown cork opener, whereby the utility of the pocket lighter will be widely extended.
• said protrusion is provided on a casing member dimensioned so as to be able to receive and releasably hold the lighter handle by insertion thereof into the casing member, whereby the casing and its associated hook will be reusable on disposable lighters of the shape to which the casing is adapted.
• FIG. 1 is a perspective view of a lighter as provided with a tool projection according to the invention.
• Fig. 2 is a similar view of a tool carrying casing member
• Fig. 3 is a bottom view of a tool insert for use with a particular type of lighters.
• Fig. 4 is a perspective view of the insert shown in Fig. 3,
• Fig. 5 is a side view illustrating the use of the lighter as a crown cork opener
• Fig. 6 is a perspective view of the hook projection in a modified embodiment of the invention.
• a conventional pocket lighter of the disposable everyday type is mounted in a casing 1, which is shown separately in Fig. 2.
• the casing 1 is provided or rather integrally produced with a solid bottom portion 2, from which a hook portion 3 projects downwardly so as to define a recess 4 adjacent the remaining bottom part 5 of the bottom portion 2.
• the casing 1, preferably, is made of a hard or semihard plastic material, which renders the thin-walled lighter receiving casing portion slightly resiliently deformable, while the solid and thick bottom portion 2 and hook 3 are hard material parts.
• the tubular lighter receiving portion is shaped so as to conform to the shape of the lighter handle or body portion, designated
• a reinforeing metallic insert may be placed in the hook portion 3 so as to be exposed at 14 (Fig. 1), i.e. at the crown cork edge engaging area of the hook portion 3.
• Many conventional lighters of the disposable type are provided with translucent fuel tank walls, whereby the remaining volume of gas liquid is directly observable.
• the tubular wall of the casing 1 should not necessarily be translucent, because the user can easily from time to time remove the casing 1 from the lighter for checking the gas level.
• the reusable casing may even improve the appearance of the lighter, and it may have a textured surface as preferred by many users.
• a lighter bottom member 6 shaped generally as the lower casing part 2 of Figs. 1 and 2 and provided with an upstanding central portion 7, which is receivable in a bottom cavity 14 of a lighter handle 13.
• the bottom member 6 is secured to the lighter, preferably under factory conditions, by glueing or welding. Should the lighter be of the
• a filling access hole 12 Fig. 3 may be provided in the bottom member 6.
• the metallic insert 14 (Fig. 1), preferably, is intended as a surface reinforcement only, for protecting the relevant surface postion of the hook member from being damaged by repeated engagements with the edges of crown corks (Fig. 5) .
• the insert 14 is constituted by an outer end portion of a thin strip of sheet steel or stainless steel, this end portion being exposed practically flush with the surrounding inner surface of the hook member 3.
• the member 14, may be secured in any suitable manner, e.g. shaped with bent holding flange portions, with which it is anchored in the plastic material upon being laid into the casting die.
• a preferred arrangement is shown in Fig. 2, where the said thin strip stretches through the material of the hook member 3 so as to have " its opposite end 15 projecting slightly up from the top surface of the bottom portion 2.
• the strip member 15 is used for the holding of the strip in its correct position in the die, such that the other end portion 14 may be correctly placed therein, and the portion 15 is left by the relevant holding and die tool when the cast member 1,2,3 is rejected from the casting machine.
• the strip member may be held so as to have the end portion 15 projecting from an outer surface portion of the hook member 3, whereby, of course, it will be necessary to remove the projection by a subsequent machining operation.
• the metallic insert 14 is usable for surface protection, it may nevertheless form an active part of the hook member 3, when its outer end is bent upwardly as shown at 16 in Fig. 6.
• the free end portion 16 projects from the outer edge area of the hook portion at such an angle that it can be eased under
• OMPI the lower crown cork edge when the unit is placed in the opener position as illustrated in Fig. 5.
• a very safe grip of the crown cork edge is ensured hereby, and the unit will be stabilized in its operative position or engagement throughout the opening operation.
• the hook has the full width of the casing 1 , but with the usual standard width of the relevant lighters the hook portion will still be usable as a pipe stopper.
