An embodiment is related to a method of manufacturing a vial for use in smoking a substance from the vial. More specifically, a method of manufacturing a disposable vial within which tobacco may be packed and smoked. An indent is provided for wrapping a wick made of hemp or similar material used to provide a long lasting flame when lit. Other embodiments are also described.
Various devices exist for smoking substances such as tobacco. The most commonly used device is a cigarette or cigar, which consists of tobacco rolled within a thin paper. The cigarette or cigar is ignited at one end and smoke, which is emitted from the tobacco (once ignited or smoldering), is inhaled or tasted from the other end. In addition to cigarettes, there are tobacco pipes which are designed to hold tobacco in a bowl formed at one end and allow the user to inhale or taste smoke or vapor emitted from the burning or vaporization of the tobacco from another end. In particular, a tobacco pipe typically consists of an upwardly facing bowl for holding the tobacco, a stem (or shank) that extends from the bowl and ends in a mouth piece (the bit). Cigarettes and cigars are disposable, while most tobacco pipes are not.
The instant invention is directed to a process of manufacturing a disposable vial for packing a substance (e.g. tobacco) to be smoked from the vial. The process may include heating a narrow section of a vial (e.g. a glass vial) in the shape of a cylindrical tube having an opening at both ends. The heated section is near one of the two ends The vial should be rotating at anywhere from 30 revolutions per minute (RPM) to 60 RPM during the entire process. After the vial is heated enough to manipulate it, in one embodiment, a tool (e.g. a graphite tool) is used to press the heated section of the vial to create an hourglass shape. Once the hourglass shape is formed, the same section of the vial is again heated. While heating, both ends of the vial are pressed together until the vial walls are flush again. In other words, the sections of the wall which form an indentation in the outer surface between each side of the hourglass shape are pressed together again so that the indentation is removed. In another embodiment, instead of using a tool to press the heated section to create the hourglass shape, as the section is being heated, both ends of the vial are pressed together while applying a roller to the outer surface of the vial adjacent to the heated section so that the vial collapses due to the pressure from the roller applied to the outer surface and the pressure supplied by both ends being pressed together. This results in the same hour glass shape being formed, but without the outside diameter of the vial being collapsed since no tool is applied to press the glass inward. The only pressure applied to outer surface is from the roller which is used to maintain the outer diameter of the vial, not press it inwards.
After the two ends of the vial are pressed together until the vial walls are flush again, a second, wider section near the middle of the vial may be heated and then stretched so that a second, wider tool, such as a graphite tool, is used to press the second, wider section of the rotating vial to form a second, wider, and indented section. This wider, indented section has a shape similar to an hour glass, but with a much longer neck portion which is formed as the tool is pressed against the heated section vial as it is rotated while being compressed from both ends until the second section has a reduced inner and outer diameter so that the finished product has an opening at one end, a short hour glass structure, an elongated, narrow middle portion and followed by a third section which extends from a second end of the narrow middle portion to the second end of the vial. The formed vial therefore has a first opening at one end adjacent to a first chamber, a short narrow portion or neck connecting the first chamber to a second chamber. The elongated middle portion extends from the second chamber to a third chamber which ends at the opening on the opposite end of the vial from the first opening. The inner and outer diameters of the three chambers may be approximately the same. The outer diameter of the hour glass shaped structure is about the same as the outer diameter of the three chambers. The inner diameter of the elongated narrow middle portion is smaller than the inner diameter of the three chambers. This diameter may be the same as, less than or greater than the diameter of the shorter, narrow section. The inner and outer diameters of the openings at the opposite ends of the vial are about the same. It is also possible to apply the heat to both sections of the vial at the same time, and apply the first and second tools at the same time to provide a same disposable vial if produced by the separate heating and pressing operations.
More specifically, in one embodiment, a method of manufacturing a vial for packing a substance to be smoked from the vial is provided. The method may include providing a vial which includes a first end portion and a second end portion connected by a tubular portion having a hollow interior. In an embodiment, a first end portion and the second end portion are initially open, but one end or both could be initially closed, with openings formed at a later time. Preferably, both openings have the same inner and outer diameters, but such diameters may differ. The method further includes forming a first chamber, a second chamber, and elongated middle portion, and a third chamber within the hollow interior of the tubular portion. The opening in the second end portion may be an inhalation port, which may be the same diameter as an opening in the first end portion, or a smaller diameter. In one aspect, the first, second and third chambers may be formed by heating a portion of a wall forming the tubular portion of the vial. Once the portion of the wall is heated, an inward pressure may be applied to the portion of the wall to collapse the wall into the hollow interior of the tubular portion to form a short neck portion within the hollow interior of the tubular portion. The short neck portion may be dimensioned to separate the first chamber from the second chamber, and the middle portion may be dimensioned to separate the second chamber from the third chamber. In one embodiment, during or after forming the short neck portion, heat may be applied to the portion of the wall forming the neck portion, and the first end portion and the second end portion of the vial are pushed toward one another until an exterior surface of the tubular portion circumferentially outward to the neck portion is flush with the rest of the tubular portion. The vial may be rotated while applying the heat and the pressure to the portion of the wall. After the tubular portion circumferentially outward to the neck portion is flush with the rest of the tubular portion, in an embodiment, heat is applied to a middle portion of the vial until the glass is hot enough to manipulate, the rotation is stopped and both ends of the tube are pulled in opposite directions which causes the middle portion to begin to collapse. Heat is again applied to the elongated middle portion and an inward pressure is applied to the middle portion as the vial is rotated. Pressure is also applied the first end portion and the second end portion and inward pressure continues to be applied to the middle portion to even out and reduce the outside diameter of the vial in the middle portion. In one aspect, if the vial is closed at the second end, the opening in the second end portion may be formed by heating the second end portion and introducing air into the opening in the first end portion until the opening in the second end portion is formed.
In another embodiment, a method of manufacturing a vial for packing a substance to be smoked from the vial includes providing a glass vial that includes a first end portion and a second end portion connected by a tubular portion forming openings at both ends. The method may further include applying heat to a section of the tubular portion to heat the section of the tubular portion and applying a pressure around the heated section of the tubular portion to collapse the section of the tubular portion into the hollow interior of the tubular portion. Collapsing the tubular portion forms a neck within the hollow interior of the tubular portion. The neck may include an opening that is narrower than an opening of the first end portion. In addition, the first end portion and the second end portion are pressed together until an exterior surface of the tubular portion surrounding the collapsed section is level with a remaining exterior surface of the tubular portion. An elongated narrowed middle portion may be formed in a similar manner except that the narrowed portion forming the elongated narrowed middle portion maintains its smaller diameter.
In another embodiment, the method of manufacturing includes wrapping a wick around the elongated narrowed middle portion.
In another embodiment, a vial for packing a substance to be smoked from the vial is provided. The vial may include a first or receiving chamber having an open end dimensioned to receive a substance to be packed within the receiving chamber. The vial may further include a second or short vapor chamber extending from the receiving chamber followed by a narrowed middle portion, and then a third vapor chamber. The third vapor chamber may have an inhalation port at a second open end for outputting a vapor from a substance within the first or receiving chamber. In addition, the vial may include a first, short neck portion positioned between the receiving chamber and the short vapor chamber preceding narrowed middle portion preceding a third chamber. The short neck portion may have a wall extending concentrically inward from an arcuate wall forming the receiving chamber and the short or second vapor chamber. The narrowed middle portion may have a wall extending concentrically inward from an arcuate wall forming the second chamber and a second arcuate wall forming the narrowed middle portion. The wall may further include an opening that is axially aligned with the open end of the receiving chamber and the inhalation port of the third chamber. In some embodiments, a diameter of the receiving chamber is equal to or less than a diameter of the elongated vapor chamber. Still further, a length of the receiving chamber may be less than a length of the elongated vapor chamber. In addition, a width of the neck portion may be less than a length of the receiving chamber and the narrowed middle portion and the elongated vapor chamber. In one aspect, the interior wall forming the elongated vapor chamber may include a first side facing the open end of the narrowed middle portion and a second side facing the inhalation port. The receiving chamber, neck portion, the narrowed middle portion and the elongated vapor chamber may be integrally formed from a glass vial.
The embodiments of the invention are illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment of the invention in this disclosure are not necessarily to the same embodiment, and they mean at least one. Also, a given figure may be used to illustrate the features of more than one embodiment of the invention in the interest of reducing the total number of drawings, and as a result, not all elements in the figure may be required for a given embodiment.
Several embodiments of the invention with reference to the appended drawings are now explained. Whenever aspects of the embodiments described here are not explicitly defined, the scope of the invention is not limited only to the parts shown, which are meant merely for the purpose of illustration. Also, while numerous details are set forth, it is understood that some embodiments of the invention may be practiced without these details. In other instances, well-known circuits, structures, and techniques have not been shown in detail so as not to obscure the understanding of this description.
The first chamber 204 may be dimensioned to receive and hold a substance (e.g. tobacco) to be smoked from vial 100. In this aspect, first chamber 204 may also be referred to herein as a receiving chamber. The second chamber 206 may be dimensioned to receive a smoke or vapor emitted from the substance within first chamber 204 which then flows through neck 214 through narrowed middle portion 104 to third chamber 207. In this aspect, in some embodiments, third chamber 207 may be referred to herein as a smoke or vapor chamber. The third chamber 207 may have a length that is greater than a length of first chamber 204 and a length second chamber 206.
In order to keep a substance packed within first chamber 204 from passing into second chamber 206, the first chamber 204 and the second chamber 206 may be separated by a neck portion 214. Neck portion 214 may be formed by an interior wall 212 that extends circumferentially inward from exterior wall 202. In one aspect, the interior wall 212 may include a first side 222 facing the first chamber 204 and opening 103 of first end 102 and a second side 224 facing narrowed middle portion 104. In this aspect, the first side 222 may form a portion of the first chamber 204 and the second side 224 may form a portion of the second chamber 206.
Interior wall 212 may include a neck 214 forming an opening of a size sufficient to allow smoke or vapor emitted from the substance within first chamber 204 to pass to second chamber 206 while still preventing the substance from passing from first chamber 204 to second chamber 206. In this aspect, in some embodiments, a diameter of the opening of neck portion 214 is less than a diameter of first chamber 204 and a diameter of second chamber 206. The diameter of first chamber 204 and the diameter of second chamber 206 may be substantially the same, or the diameter of first chamber 204 may be less than a diameter of second chamber 206 and third chamber 207. In addition, it is noted that in some embodiments, a width of interior wall 212 is less than a length of first chamber 204 and a length of second chamber 206. In this aspect, interior wall 212 is not considered to occupy a substantial area of the hollow interior 108.
It is further noted that in some embodiments, the opening of neck portion 214 is axially aligned with the opening 107 to third chamber 207. In other words, each of first opening 103, the opening in neck 214, the opening through narrowed middle portion 104, and second opening 107 are aligned along a longitudinal axis 220 of vial 100. Said another way, the entire length of vial 100 may be substantially straight such that it is symmetrical about axis 220, and in turn, each of first end opening 103, opening in neck 214, the opening 230 between second chamber 206 and narrowed middle portion 104 and second end opening 107 are also symmetrical about axis 220.
As shown in
It should be noted that although specific processing parameters (e.g. rotation speed) may be disclosed herein, the parameters can vary depending upon, for example, the machine speed. For example, the heating time of the vial during any processing step disclosed herein depends on machine speed, which may produce around 22 parts per minute (ppm) plus or minus 2 ppm at a rotation speed of for example, from 30-60 RPM depending on machine speed and desired result. At 22 ppm, heat is applied for about 3 seconds per piece. As noted above, the specific temperatures, and times are dependent on the specifics of the glass or other material used to make the vial. Such specifics are well known to persons having ordinary skill in the art and therefore need not be further disclosed herein.
After processing operation 901 is completed, the vial forms a shape as described with reference to
While certain embodiments have been described and shown in the accompanying drawings, it is to be understood that such embodiments are merely illustrative of and not restrictive on the broad invention.
