Description

FIELD

The inventions herein related to the field of smoking devices, and more particularly the inventions herein relate to the field of devices for smoking combustible materials.

BACKGROUND

Smoking devices are generally known which include a container for housing a quantity of tobacco or other combustible or burnable plant material used with the device. Pipes often include such a container and have an opening to the container to permit burning of the combustible material, as well as a mouthpiece which is connected by an open channel to the container for inhaling the smoke generated by the burning plant material.
Unfortunately, such smoking devices do not burn uniformly. Moreover, existing smoking devices continue to burn until manually extinguished by the user, wasting material and preventing the user from quickly storing the device. Furthermore, such devices inefficiently use the material burned therein.

SUMMARY

Accordingly, an improved pipe is disclosed. The pipe has an elongate body having an inlet opening and a mouthpiece with an aperture. An internal bore is provided within the elongate body connecting the inlet opening and the mouthpiece aperture. The internal bore has a bolus chamber with an inlet orifice aligned with the inlet opening and an exit orifice aligned with the internal bore opposite the inlet orifice. The inlet orifice has a smaller diameter than the exit orifice. The pipe is also self-extinguishing.
A pipe is also disclosed which has an internal bore with a cavity for holding combustible material. The cavity has inlet and exit orifices that create a venturi effect when the pipe is in use.
A pipe is further disclosed which includes a bolus chamber having an inlet orifice and an exit orifice which is larger than the inlet orifice.
These and other features and advantages of devices, systems, and methods according to this invention are described in, or are apparent from, the following detailed descriptions of various examples of embodiments.

DETAILED DESCRIPTION

Referring to the Figures, a pipe 100, 200 is provided. As shown in FIGS. 1-4, the pipe 100 comprises an elongate tubular body 102 having an internal bore 104 or channel. The pipe body 102 has an inlet end 106 and a mouthpiece end 108. The inlet end 106 has an opening 110 or aperture and the mouthpiece end 108 has an opening 112 or aperture. Within the pipe body 102 is a bolus chamber 114 or container or cavity that is joined to, and open to, the bore 104 or channel so as to form a continuous passageway or channel from the inlet end opening 110 to the mouthpiece end 108 and opening 112.
The continuous passageway, the bore and/or the channel may be any suitable length and/or diameter accomplishing the solutions provided herein. In one or more examples of embodiments, the continuous passageway may have varying diameter. In this regard, the bolus chamber 114 or cavity or container comprises an expanded bored area relative to the channel and includes an inlet orifice 116 which may be coterminous with or connected to the inlet end 106 or inlet opening 110 of the pipe body 102, and an exit orifice 118 separated from, and in the illustrated embodiment on an opposing side of, the bolus chamber 114. The exit orifice 118 or outlet side has a longer bore 104, or is otherwise joined to the bore 104 or channel ending to the mouthpiece end 108. The inlet orifice 116 and exit orifice 118 may be axially aligned such as shown in FIG. 4.
The inlet orifice 116 may range from between approximately 0.050 inches to approximately 0.125 inches in diameter, while the exit orifice 118 may range from approximately 0.065 inches to approximately 0.140 inches in diameter. In one or more examples of embodiments, the inlet orifice 116 and the exit orifice 118 are two different size orifices. Preferably, the inlet orifice 116 and exit orifice 118 are arranged to provide a venturi effect. In other words, the orifices of the continuous pathway cause a reduction in fluid pressure that results when a fluid (e.g., a gas) flows through a constricted section (or choke) of the pipe 100. In particular, the inlet orifice 116 of the bolus chamber 114 is smaller than the exit orifice 118. More specifically, the inlet orifice 116 has a smaller diameter than the exit orifice 118. To this end, the variation in orifice size between the inlet orifice 116 and exit orifice 118 ranges from a ratio of approximately 1:1.12 to approximately 1:1.3.
As shown in FIGS. 5-8, the pipe 100, 200 may be formed of multiple components which are secured together. In particular, as can be seen, the pipe body 102 includes a removable cap 120. The cap 120 may be secureable/removable by any suitable mechanism. In the illustrated embodiment, the body 102 has a threaded end 122 which mates with a corresponding thread 124 on an inner surface of the cap 120. Alternatively, the cap 120 may be secured by friction fit, tongue and grove, and/or other now known or future developed mechanical mechanisms. Preferably, the cap 120 is easily removable/securable for access to, loading of, and cleaning of the bolus chamber 114, and internal bore 104 of the pipe 100. In one or more examples of embodiments, such as illustrated in FIG. 8, the bolus chamber 114 may be formed by a first section 126 contained within the body 102 (e.g., an internal cavity) and a second section 128 contained within the cap 120 (e.g., an internal cavity). The cap 120 may also include the inlet end 106 and inlet orifice 116. Optionally, an O-ring or other sealing mechanism (not shown) may be used to seal the connection between the cap 120 and the body 102.
In one or more further examples of embodiments, one or more pipes 100, 200 may be combined and used with a water container 130 or water bath to form a water pipe 300. As shown in FIG. 9, the water container 130 has a pipe opening 132 into which the mouthpiece end 108 of a pipe 100, 200 is inserted. The water container also includes an exit end 134 for exhausting of the gases from the pipe and water vapor combination. In one or more further examples of embodiments, an O-ring or other sealing mechanism (not shown) may be used with the water container 130, and provided at the pipe opening of the water container for engaging the pipe inserted therein.
The pipe 100, 200 described herein may be formed of any suitable material which accomplishes the objects described herein. For example, the pipe material must withstand heat and/or exposure to flame. In addition, the pipe material is easy to clean and has sufficient hardness to be durable. In one or more particular examples of embodiments, the pipe 100, 200 is formed of D2 tool steel, although variations thereon may also be acceptable. In one or more examples of embodiments, the pipe 100, 200 may be cast or molded. In alternative examples of embodiments, the pipe 100, 200 may be precision cut. Moreover, the pipe 100, 200 may be constructed of more than one component as discussed hereinabove, which are subsequently secured together. In one or more additional examples of embodiments, the material may be optionally treated, such as with a coating or other manufacturing process to achieve the desired operating parameters. In the case of a water pipe 300, the water container 130 or water bath may be formed of glass or other suitable material.
One or more examples of use of the pipe 100, 200 will now be described. In one example of embodiments, a user opens the pipe 100, 200 by removing the cap 120. Removing the cap 120 reveals the bolus chamber 114 within the pipe. The user then loads the bolus chamber 114 with a quantity of combustible or burnable material to be smoked. The cap 120 is then secured on the body 102. The user may then expose the pipe, and preferably the area of the pipe corresponding to or surrounding the bolus chamber 114, to heat or a flame, thereby causing the combustion of the material and generation of smoke or gas. The user inhales the gas from the mouthpiece end 108, which draws in air from the smaller inlet opening 110 and inlet orifice 116. The air passes through the bolus chamber 114 and carries with it the smoke or gas generated into and through the exit orifice 118, through the bore 104 and out the aperture in the mouthpiece. When the flame or heat is removed, the material contained within the pipe self-extinguishes shortly thereafter.
A pipe 100, 200, 300 having the foregoing features has many advantages not realized by existing devices. For instance, the variation in orifice sizes causes the combustible material within the bolus chamber to burn with a fairly uniform burn and also to self-extinguish. As a result, the material is preserved or conserved within the bolus chamber, and the pipe can be quickly stored, e.g., safely deposited in a pocket, shortly after use. In addition, the variation in orifice sizes creates a venture effect, limiting extraneous gases from entering the chamber, and efficiently using or maximizing the output of the material burned in the pipe. In one or more further examples of embodiments, the pipe of the type and material described herein is easy to clean and is durable.
