Cigar ventilation implement

Abstract

A cigar ventilating implement includes both a cylindrical punch and a piercing member such as a needle or spike. The cylindrical punch and piercing member are each is extendable from an outer housing of the implement by gripping laterally extending flanges and pressing on an actuator in a manner similar to that used to operate a medical syringe. The cylindrical punch is extendable to a predetermined distance when pushing the actuator over a first section of its total range of movement after which the piercing member may be extended from the cylindrical punch by a further distance upon pushing the actuator over a second section of its total range against the bias provided by a coil spring. The restoring force of the coil spring causes the elongated piercing member to retract back into the cylindrical punch when pressure on the actuator is released.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a cigar ventilation implement, and in particular to a cigar ventilation implement that includes both (i) a punch for forming an opening in a binder or wrapper at an end of the cigar, and (ii) an elongated piercing member such as a needle or spike for additionally forming an axial passage having a selectable depth. The punch enables removal of the binder or wrapper from an area coextensive with the end of the cigar in order to prepare the cigar for smoking, while the elongated piercing member enables the smoker to modify the passage of smoke through the cigar according to the user's preference in order to enhance the smoking experience.

2. Description of Related Art

Cigars are generally cylindrical rolls of tobacco characterized by cut, dried and fermented tobacco leaves encased in a binder and/or wrapper of relatively thicker leaves. Conventional cigars are typically formed with an open end, which is the end that is exposed to a flame in order to light the cigar, and a closed end. In order to prepare the cigar for smoking, the closed end must be cut, punched, or pierced to allow smoke-carrying air to be drawn from the lit open end through the main body of the cigar, the smoke-carrying air exiting the cigar into the smoker's mouth through the cut, punched or pierced end.

The most common method of ventilating a cigar in order to prepare it for smoking is to use a cutting implement, such as a guillotine-like cutter, to slice off the closed end of the cigar. However, slicing off the closed end can leave bits of loose tobacco that may end up in the smoker's mouth, and is a relatively wasteful way to achieve ventilation. In addition, cigar cutting implements are typically relatively large and require a degree of skill or dexterity to achieve an optimal cut that may be beyond that of the occasional smoker, the elderly, or disabled users. A bad cut cannot be reversed, and can ruin an expensive cigar.

Another known method of ventilating a cigar is to use a needle or spike to pierce the closed end of the cigar and form an axial passage. Such cigar-piercing spike or needle devices have a number of advantages over cigar cutters, including the relatively small size of the needle or spike, which allows it to fit on a keyring or otherwise to be easily carried, and the ability of the needle or spike to penetrate the cigar to a controllable depth, which can ameliorate the effects of a smaller diameter passage. In addition, use of a needle or spike to pierce the closed end of the cigar is less wasteful than cutting, and solves the problem of loose tobacco leaves. However, this alternative has the disadvantage, for true cigar aficionados, that the relatively small diameter of the passage for smoke prevents smoke from passing through the full cross-section of the cigar, which can result in a duller flavor and a less satisfying experience. The best cigars have specially selected leaves that differ along the length and/or diameter of the cigar, and cannot be fully experienced if the passage of smoke is limited to the diameter of a needle or spike.

Yet another known method of ventilating a cigar is to use a cylindrical cigar punch to removes a circular piece of the end wrapper and provide a relatively large diameter opening in the cigar end, thereby permitting a relatively large volume of smoke to pass through the entire cross-section of the cigar, while at the same time presenting. Unlike a cutter or piercing device, however, the cylindrical punch does not provide a way for the user to control the depth of the opening and thereby customize the smoking experience by controlling the passage of smoke through the cigar.

To overcome the above-described shortcomings of conventional cigar ventilating implements, the inventors of the improved cigar ventilation implement described herein have devised a way to combine a punch and a needle or spike-type piercing tool, in a single implement that does not require enhanced skills or dexterity to manipulate and that can easily be carried by the user. The improved cigar ventilation implement thus has advantages of both the punch and the piercing tool, including the formation of a relatively large-diameter opening to enable the full cross-section of the cigar to be enjoyed, and the provision of an axial passage having a controllable depth. Furthermore, the invention has additional advantages of providing for retraction into the device of both the punch and piercing implement to ensure safety, as well as an especially simple and easy-to-assemble construction in comparison with conventional cutters.

By way of background, U.S. Pat. No. 4,733,674 shows an example of a prior art plunger-actuated needle or spike-type cigar-piercing ventilating implement that includes a flange for providing leverage when operating the plunger in a manner similar to a medical syringe. The plunger-actuated ventilating implement operates in a manner similar to that of the invention, but without an additional extendable punch. Other examples of cigar piercing devices that utilize a needle or spike but that do not include an additional punch are found in U.S. Pat. Nos. 1,734,620 and 4,733,674, U.S. Patent Publication No. 2009/0183743, German Patent Publication No. DE 202018002142, and Korean Publication No. 1999-099403.

U.S. Pat. No. 5,852,808 is of interest because it includes both a fixed punch and a retractable needle. Because the punch is not extendable and retractable, the ventilating implement requires an additional screw-on cover to ensure that the cutting blade on the punch is not exposed when not in use. A similar arrangement of a piercing device with a cutting blade and a spike-like structure extendable into the cutting blade for pushing a cut plug out of the punch is disclosed in U.S. Patent Publication No. 2011/0146696.

On the other hand, U.S. Patent Publication No. 2009/0133705 discloses a cigar ventilator with fixed spike-like structure and a retractable cylindrical punch. However, the fixed spike-like structure at the center of the retractable cylindrical punch is used to eject the tobacco plug when the cylindrical punch is retracted, rather than serving as a retractable piercing device that is in addition to the retractable punch. U.S. Pat. No. 308,906, which issued in 1884, also shows a piercing device with a cutting blade and a punch that extends into the cutting blade for ejecting the cut plug.

Finally, by way of further background, U.S. Pat. No. 5,836,318 shows a cigar ventilating arrangement with a rotatable piecing device, U.S. Patent Publication No. 2010/0000553 discloses a cigar cutter with a rotatable piercing device that is combined with a pen, U.S. Pat. No. 925,158 discloses a combined cigar cutter and perforator, U.S. Pat. No. 8,485,200 discloses a combined cigar punch, flashlight, and keyring, and U.S. Pat. Nos. 5,738,117 and 5,913,676 are representative of numerous prior patents and publications that disclose a combined cigar cutter and lighter.

SUMMARY OF THE INVENTION

It is accordingly an objective of the invention to overcome the disadvantages of the prior art by providing a cigar ventilating implement that enables a user to prepare an end of the cigar for smoking by either piercing or punching the end of the cigar, or both, and yet that has a simple and reliable construction, is easy-to-use, and can be safely, conveniently, and discretely transported by the user so as to be available for use any time the user wishes to enjoy a cigar.

It is a further objective of the invention to provide a cigar ventilating implement that provides the user with the option of punch-cutting the end of a cigar, piercing it, or a combination of punching and piercing according to the user's preference, in order to optimize cigar preparation for different types of cigar, with minimal risk of A cutting error that might ruin the cigar.

It is also an objective of the invention to provide a cigar ventilating implement that meets at least one of the above objectives and yet that is relatively inexpensive to manufacture or assemble.

These objectives are achieved, in accordance with a preferred embodiment of the invention, by a cigar ventilating implement that includes both a cylindrical punch and a piercing member such as a needle or spike, arranged coaxially and each extendable from an outer housing of the implement by gripping laterally extending flanges and pressing on an actuator in a manner similar to that used to operate a medical syringe. In a preferred embodiment of the invention, the cylindrical punch is extendable to a predetermined distance when pushing the actuator over a first section of its total range, after which the piercing member may be extended by a further distance upon pushing the actuator over a second section of its total range. A coil spring is provided to ensure retraction of at least the piercing implement back into the cylindrical punch when pressure on the actuator is released, while retraction of the cylindrical punch into the outer housing may be achieved by pulling up on the actuator or pushing up on the punch, to enable safe transport and storage of the implement.

In the preferred embodiment, the cigar ventilating implement requires only four main parts to provide both the retractable punch and the retractable elongated member, although those skilled in the art will appreciate that details of the construction may be varied by, for example, constructing the four main parts of separate units, or adding separate additional parts such as bushings, washers, o-rings. As a result, the detailed description and drawings included herein should not be considered as limiting, variations or modifications of the illustrated embodiment being possible without departing from scope of the invention.

Although illustrated below as a stand-alone device or implement, the cigar ventilating implement of the invention may be combined with a lighter or any other object or device, including by way of example and not limitation, a conventional cigar cutter, a pocket or utility knife, a key ring, and/or a flashlight.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Throughout the following description and drawings, like reference numbers/characters refer to like elements. It should be understood that, although specific exemplary embodiments are discussed herein there is no intent to limit the scope of present invention to such embodiments. To the contrary, it should be understood that the exemplary embodiments discussed herein are for illustrative purposes, and that modified and alternative embodiments may be implemented without departing from the scope of the present invention.

As shown in FIG. 1, the cigar ventilation implement 1 of a preferred embodiment of the invention includes an outer housing 2, a cylindrical punch 3, an actuator/piercing member 4, and a coil spring 6.

Outer housing 2, illustrated in FIGS. 1-3, 5A, and 5B, includes a cylindrical main section 7 and a flange 8. The flange 8 extends in a generally perpendicular direction from a lower section 9 of the main section 7, and includes a lower surface 10 that is gripped by a user's fingers to provide resistance to forces caused by pushing on the actuator 4.

The actuator/piercing member 4, as illustrated in FIGS. 1-4, includes both a plunger section 11 and an elongated needle or spike-like piercing member 5. The plunger section 11 and piercing member 5 may be formed in one piece by, for example, plastic extrusion molding of a plastic material or metal casting, or may be formed separately, either of the same material or different materials, and joined together to form an integrated piece. As a result, it will be appreciated that numerous different materials and methods of construction of the actuator/piercing member 4 will occur to those skilled in the art, and that the invention should not be limited to any particular material(s) or method of construction or assembly.

As illustrated in FIGS. 1-4, the actuator/piercing member 4 is inserted into the outer housing 2 from a top end that is opposite the lower section 9 from which the flange 8 extends, and is axially movable within the outer housing 2. In order to support the plunger 11 and facilitate movement of the actuator/piercing member 4, an annular bearing 12 may be installed in the main body section 7 of the outer housing 1. Bearing 12 may be in the form of a washer, o-ring, detents extending from the inner surface of the outer housing 2, or any other structure capable of supporting the actuator/piercing member 4 for axial movement without excessive friction that would interfere with the axial movement.

The cylindrical punch 3, as illustrated in FIGS. 1-3, 7A and 7B, is also slidably positioned with respect to the outer housing 2, and is attached to the plunger 11 by coil spring 6 so that the elongated piercing member 5 extends coaxially through both the coil spring 6 and the cylindrical punch 3, and so that a tip 21 of the elongated piercing member 5 is initially situated near a lower end of the punch 3. An outwardly extending projection, collar or flange 17 at the top end of punch 3 engages a corresponding inwardly extending surface or lip 18 at the bottom end of the outer housing 2 to limit travel of the punch 3 in a downward direction.

The main body 20 of the punch is in the form of a cylinder that extends downwardly from the collar or flange 17, the distal end of the cylinder forming a cutting edge that cuts out a circular section of a the binder or wrapper covering the closed end of the cigar so that the binder or wrapper can be removed to enable passage of air and smoke. The distance between the bottom of collar or flange 17 and the cutting tip at the bottom of the main body 20 defines the maximum distance by which the cutting tip of the main body 20 will extend from the outer housing 2. This distance must be sufficient to enable punching of the cigar wrapper irrespective of the curvature of the cigar end. The material and manner of forming the punch 3 form no part of the invention, although metal punches are generally preferred as they are better able to maintain a cutting edge that can penetrate the cigar wrapper or binder.

The plunger 11 of the slidably positioned actuator/piercing member 4 includes an upper surface 13 that is engaged by the user's thumb when the lower surface 10 is gripped by fingers of the user, in a manner similar to the manner in which a medical syringe is gripped and operated. When the plunger is in a topmost position, the tip 21 of the needle or spike-like piercing member 5 is initially retracted into the punch 3, and the punch 3 is retracted into the outer housing 2. The punch 3 is attached to the plunger section 11 of the actuator/piercing member 4 solely by the coil spring 6, so that the punch 3 initially moves with the plunger 11 as the plunger 11 is pushed in a first direction, illustrated in FIGS. 1-3 as downward, from the initial topmost position shown in FIG. 1 to an intermediate position shown in FIG. 2, by pressing the upper surface 13 while gripping lower surface 10. Those skilled in the art will appreciate that the manner in which the coil spring 6 is attached to the plunger 11 and the punch 3 is optional and may be freely selected without departing from the scope of the invention.

When the actuator/piercing member 4 has been pushed to the intermediate position shown in FIG. 2, the collar or flange 17 of the punch engages the lip or shoulder 18 of the outer housing 2. In this position, the punch 3 is fully extended from the outer housing 2, as shown in FIG. 2, but the tip 21 of the needle or spike-like piercing member 5 is still within the punch 3. Subsequently, further pushing on the upper surface 13 by the user of the plunger 11 in the first or downward direction is opposed to a bias force provided by the coil spring 6. This occurs because further downward movement of the cylindrical punch 3 is opposed by engagement of the flange 17 and lip or shoulder 18, resulting in compression of the coil spring 6 as the plunger 11 continues to be pushed downward. Since the needle or spike-like piercing member 5 is integral or formed in one piece with the plunger 11, the needle or spike-like piercing member 5 moves relative to the extended cylindrical punch 3, from the position shown in FIG. 2 to the position shown in FIG. 3. The position shown in FIG. 3 is the lowermost position of the piercing member 5, which determines the maximum depth that the piercing member can be extended into a cigar to form a passage, but the user is free to stop pushing on the plunger 11 at any point in between the position shown in FIG. 2 and the lowermost position shown in FIG. 3, thereby allowing the user to control the depth of the passage formed by penetration of the piercing member 5 into the cigar.

As described above, the initial pressure on the plunger 11 results in the extension of the cylindrical punch 3 in order to form an opening in the end of the cigar by cutting a circular section of having a diameter corresponding to the diameter of the punch out of the end wrapper or binder. Further pressure on the plunger 11 results in extension of the elongated, needle or spike-like piercing member 5 to a desired depth within the cigar, thereby allowing the user to control the depth of the passage formed in the cigar according to the user's preference and the characteristics of the cigar being pierced.

Release of the initial pressure on the plunger 11 results in immediate retraction of the elongated needle or spike-like piercing member 5, i.e., movement is a second direction opposite the first direction, from the position shown in FIG. 3 to the position shown in FIG. 2, in response to the restoring force provided by the compressed coil spring 6. At this time, the tip 21 no longer extends from the punch, eliminating any hazard posed by the relatively sharp tip. Further retraction of the punch 3 and piercing member 5 back into the outer housing 2 (from the position shown in FIG. 2 to the position shown in FIG. 1) may be accomplished by manually pulling up on the plunger 11, by manually pushing up on the punch 3 or down on the housing 2 while the punch 3 engages a surface or, optionally, by the inclusion of a second spring or biasing member (not shown) connected between the plunger 11 and the outer housing 2.

While the outer housing 2 is illustrated as having a shape similar to that of a medical syringe, it will be appreciated that the shape of the outer housing may be varied, and that the implement may be combined or integrated with other objects or devices including, by way of example and not limitation, a conventional cigar cutter, a pocket or utility knife, a key ring, and/or a flashlight. Other possible variations include variations in the shape of the tip 21 of the elongated piercing member 5, which may be rounded or flat rather than pointed; variations in the shape of the distal or cutting end of the punch 3; and the addition of a camming mechanism similar to that of a ball point pen for the purpose of latching the punch 3 in the extended position while still permitting axial sliding movement of the elongated piercing member 5 relative to the punch 3 when the punch is in the extended position.
