STORAGE TUBE AND SAVER FOR SMOKING MATERIAL

Abstract

A storage tube for a smoking material includes a hollow tube extending along a central longitudinal axis from an open first tube end to a closed or closable second tube end. The tube has a sidewall with an inside surface and a cross-sectional dimension sized to receive a smoking material, wherein the second tube end has a lower inside end surface extending transversely to the central longitudinal axis. An upper end cap is removably attachable to the first tube end and forms an air-tight seal. A rigid protrusion extends axially into the tube from the lower inside end surface and has a protrusion body and a protrusion tip. The protrusion defines a gap between the protrusion body and the inside surface of the sidewall. Optionally, the protrusion is removable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] The preferred embodiments of the present invention are illustrated in FIGS. 1-6. FIG. 1 illustrates an elevational view of one embodiment of a storage tube 10 for smoking material, such as a cigar, cigarette, or the like. The storage tube 10 includes a hollow tube 12 extending along a central longitudinal axis 14 from a first or upper tube end portion 16 to a second or lower tube end portion 18. In one embodiment, the tube 12 is cylindrical, however, other cross-sectional shapes are acceptable, such as rectangular or hexagonal. In one exemplary embodiment, the tube 12 has one or more sidewall 13 with inside surface 13a, where the sidewall 13 has a thickness of about 0.15-0.175 inch when outside diameter 13b is about 1.25 inch. Accordingly, the tube 12 is preferably sized to receive a smoking material 5 (e.g., a cigar shown in FIG. 4) of a predefined length and ring gauge and to allow the smoking material 5 to easily slide out of the tube 12 when the tube 12 is inverted.

[0025] An upper-end cap 30 is removably attachable to the first end portion 16 and preferably forms an air-tight seal with the tube 12 when attached. The tube 12 has either a closed second end portion 18 or a lower-end cap 40 that is removably attachable to the second end portion 18. Preferably the lower-end cap 40 is capable of forming an air-tight seal with the tube 12 when attached. In one embodiment, upper-end and lower-end caps 30, 40 engage the tube 12 with threads, a slip fit, a press fit, an interference fit, or other suitable method that retains the caps 30, 40 on the tube 12. Optionally a sealing member 47, such as a gasket, elastomeric seal, or O-ring (shown in FIG. 2), may be employed to provide an air-tight seal between caps 30, 40 and tube 12. Upper end cap 30 has an upper inside end surface 32 and lower end cap 40 has a lower inside end surface 42, where the inside end surfaces 32, 42 generally extend across the tube 12 transverse to the central longitudinal axis 14. In one embodiment, the upper inside end surface 32 is flat and extends perpendicular to the central longitudinal axis 14. In other embodiments, the upper inside end surface 32 is concave or domed for receiving a rounded butt-end 8 of a cigar or other smoking material 5 (shown, e.g., in FIG. 5.) A rigid protrusion 50 extends axially from the lower inside end surface 42 and includes a protrusion body 52 that extends axially to a protrusion tip 54.

[0026] Referring now to FIG. 2, a partial sectional view illustrates a part of the tube 12 together with one embodiment of the lower end cap 40. When the lower end cap 40 is assembled with the tube 12 as shown (or when tube 12 has a closed second end portion 18), the protrusion 50 defines a gap 56 between the inside surface 13a of the sidewall 13 and the protrusion body 52. When the smoking material is placed in the storage tube 10 oriented in a vertical position, the protrusion 50 supports the smoking material on the protrusion tip 52. As such, the smoking material (e.g., a cigar) is elevated above the lower inside end surface 42 and ash collects in the gap 56.

[0027] In one embodiment, the gap 56 extends completely around the protrusion body 52 in a circumferential direction. That is, no portion of the protrusion body 52 or the protrusion tip 54 extends to contact or nearly contact the sidewall 13. In other embodiments, the gap 56 comprises two or more distinct gap compartments (not shown), such as when the protrusion 50 defines a wall or plus shape that extends between opposite portions of the sidewall(s) 13. In some embodiments, the protrusion body 52 extends at its lower end 52a substantially to the inside surface 13a of the sidewall 13 so that the protrusion 50 defines or comprises the entire lower inside end surface 42. In one embodiment, the protrusion body surface 52 and inside end surface 42 define an angle a of about 45. Other values of angle a are acceptable.

[0028] In one embodiment, the tube 12 and the end caps 30, 40 are made of aluminum, copper, titanium, steel, or other metal. Other materials are acceptable for the tube 12 and the end caps 30, 40, particularly flame-resistant materials, such as some carbon fiber composites, glass, and some polymers.

[0029] Turning now to FIGS. 3A-3G, exemplary embodiments of the lower end cap 40 are shown in perspective illustrations. Although the embodiments of the lower end cap 40 are illustrated as having a threaded sidewall and circular cross-sectional shape to engage a cylindrical tube 12, other geometries and fits are contemplated.

[0030] For example, the lower end cap 40 may be configured for an interference fit with the tube 12 having a square, triangular, polygonal, or other cross-sectional shape. In general, the protrusion 50 may be a solid or hollow structure depending on cost and manufacturing constraints, the desired capacity to absorb heat from the smoking material, and other considerations.

[0031] FIG. 3A illustrates an embodiment of the lower end cap 40 where the protrusion 50 generally has a frustoconical shape. The protrusion body surface 52 extends linearly from the lower inside end surface 42 to a flat protrusion tip 54 having a round shape with a diameter of about 0.10-0.20 inch.

[0032] FIG. 3B illustrates an embodiment of the lower end cap 40 similar to the embodiment shown in FIG. 3A, except that protrusion tip 54 is domed or rounded. In one embodiment, the protrusion tip 54 has a radius of curvature from about 0.18 to about 0.20 inch.

[0033] FIG. 3C illustrates another embodiment of the lower end cap 40 where the protrusion body 52 is shaped as a cylindrical post extending to a flat protrusion tip 54 that extends substantially perpendicularly to the central longitudinal axis 14 of the tube 12 when assembled together. Similarly, the protrusion body 52 could have a rectangular, hexagonal, octagonal, or other cross-sectional shape. In one preferred embodiment, the protrusion 50 is centered on the lower inside end surface 42.

[0034] FIG. 3D illustrates another embodiment of the lower end cap 40 where the protrusion 50 has a rounded or domed shape that substantially defines a hemisphere with a radius R.sub.p substantially equal to the radius R of the lower inside end surface 42. In this embodiment, the protrusion tip 54 is an area on the protrusion 50 that makes contact with the lit end of the smoking material. Typically, the area of the protrusion tip 54 making contact with the smoking material is within a diameter of about 0.2 inch.

[0035] FIG. 3E illustrates yet another embodiment of the lower end cap 40 where the protrusion 50 has a domed protrusion tip 54 connected atop a protrusion body 52 of a reduced diameter, where the protrusion 50 approximates the appearance of a mushroom. In some embodiments, the protrusion body 52 is cylindrical, however, other cross-sectional shapes are acceptable, including solid and hollow variations thereof.

[0036] FIG. 3F illustrates yet another embodiment of the lower end cap 40 similar to the embodiment of FIG. 3A, where the protrusion 50 has a generally frustoconical shape except that the protrusion body 52 includes a plurality of wedge-shaped recesses 57 extending radially out from a central protrusion body portion 52a. As illustrated, the central protrusion body portion 52a has a cylindrical shape, but it may have other polygonal shapes. In one embodiment, the recesses 57 begin at a radius R.sub.1 of about 0.1-0.3 inch from the central longitudinal axis 14. The recesses 57 capture ash falling from the smoking material while also allowing the protrusion 50 to more effectively dissipate heat to the surrounding air and tube 12.

[0037] FIG. 3G illustrates yet another embodiment of the lower end cap 40 where the protrusion 50 has a plus shape as viewed from above, where the plus shape is defined by two intersecting walls extending axially from the lower inside end surface 42. In this embodiment, the protrusion body 52 is defined by intersecting walls in a plus shape (+) and the protrusion tip 54 is defined by the plus-shaped top surface of the walls. Such an embodiment provides a larger gap 56 than some other embodiments and therefore is able to receive more ash from the smoking material. Similarly, the protrusion could have a star shape or other shape constructed from a plurality of walls that intersect or meet at or near the central longitudinal axis 14.

[0038] Referring now to FIG. 4, a front perspective illustration shows another embodiment of the lower end cap 40 and the protrusion 50, where the protrusion 50 is a distinct structure from the lower end cap 40. For example, the protrusion 50 is sized to be received on the lower inside end surface 42 of the lower end cap 40 or closed lower end portion 18 (shown in FIG. 1) of the tube 12. In some embodiments, the protrusion 50 includes a lower protrusion flange 53 that extends partially or completely around a lower protrusion end 59. For example, the lower protrusion flange 53 has an annular shape that extends radially outward from and circumferentially around a lower protrusion end 59. In one embodiment, the lower protrusion flange 53 is constructed to be trapped between lower end cap 40 and a corresponding lip 17, surface, or feature on tube 12, thereby securing the protrusion 50 in the lower end portion 18 of the tube 12.

[0039] In other embodiments, the protrusion 50 engages the lower inside end surface 42 with a snap fit, threaded engagement, or other suitable engagement to removably retain the protrusion 50 on the lower end cap 40.

[0040] In yet other embodiments, the protrusion 50 is placed unrestrained on the lower inside end surface 42 and is held in position by the smoking material 5 being placed into the storage tube 10. By making the protrusion 50 separate and removable from the lower end cap 40 and/or storage tube 10, the user may select the protrusion 50 with a shape that is best for the chosen smoking material and/or best suits the user's aesthetic taste.

[0041] Referring now to FIGS. 5 and 6, one embodiment of the lower end cap 40 is shown in use with smoking material 5 (e.g., a cigar) supported at its lit end 7 by the protrusion 50. The tube 12 and upper end cap 30 are omitted from view in FIG. 5 for clarity. FIG. 6 illustrates a cross-sectional view of the tube 12 with the upper end cap 30 and the lower end cap 40 installed. In both of FIGS. 5 and 6, the smoking material 5 is oriented vertically with the lit end 7 pointing downwards and supported by the protrusion 50.

[0042] As the smoking material 5 burns, the lit end 7 assumes a somewhat conical or tapered shape with the outside portion of the lit end 7 becoming ash. The tip 7a of the lit end 7 of the smoking material 5 can be brought into contact with and supported by the protrusion tip 54. When the lit smoking material 5 is placed into the storage tube 10, ash 9 falls from the lit end 7 and accumulates in the gap 56 between the protrusion 50 and the inside surface 13a of the sidewall(s) 13. Since the protrusion tip 54 is elevated relative to the lower inside end surface 42, ash 9 collects in the gap 56 away from the lit end 7.

[0043] When made of appropriate materials, the protrusion 50 conducts heat away from the lit end 7 and dissipates it to the tube 12 and the surrounding environment. As such, the storage tube 10 stays cool to the touch even after inserting a lighted smoking material. After inserting the smoking material 5 into the tube 12, the upper end cap 30 is installed to seal the tube 12 from the outside air, thereby snuffing out the smoking material 5. Since the storage tube 10 is preferably sized for a specific length and ring gauge of smoking material 5, the smoking material 5 remains positioned on the protrusion tip 54 with little space to move.

[0044] In use, the user removes the upper end cap 30 from the storage tube 10 and inserts a lighted smoking material 5, such as a cigar. The smoking material 5 is supported by the tip 7a of the lit end 7, which contacts the protrusion tip 54. After installing the upper end cap 30 on the tube 12, the smoking material 5 is extinguished. The user may then stow the storage tube 10 with smoking material 5 in a pocket or other location so that the user may return to continue smoking the smoking material 5 at a later time. Embodiments of the storage tube 10 safely receive and extinguish lighted smoking material 5 and collect ash 9 away from the lit tip 7 without heat of the smoking material 5 burning the user or the user's clothing or fabrics. The storage tube 10 also avoids excessive accumulation of ash 9 on the lit tip 7 of the smoking material 5 and retains the ash 9 for later disposal where it does not soil clothing, handbags, or the like.

[0045] Although the preferred embodiments of the present invention have been described herein, the above description is merely illustrative. Further modification of the invention herein disclosed will occur to those skilled in the respective arts and all such modifications are deemed to be within the scope of the invention as defined by the appended claims.
