Abstract

A vial for packing a substance to be smoked from the vial and a method of manufacturing the vial, the method of manufacturing including providing a glass vial, the glass vial having a first end portion and a second end portion connected by a tubular portion having a hollow interior, the first end portion being open and the second end portion being closed; applying heat to a section of the tubular portion to heat the section of the tubular portion; 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; pressing the first end portion and the second end portion together until an exterior surface of the tubular portion surrounding the collapsed section is level with a remaining exterior surface of the tubular portion; and forming an opening in the second end portion.

Claims

1. A method of manufacturing a vial for packing a substance to be smoked from the vial, the method comprising:

providing a glass vial, the glass vial having a first end portion and a second end portion connected by a tubular portion having a hollow interior, the first end portion is open to an end chamber having a first inner diameter that is continuous in size to the open first end portion, and the end chamber is connected to a receiving chamber having a second inner diameter that is larger than the first inner diameter, and the second end portion is closed;

applying heat to a section of the tubular portion between the receiving chamber and the second end portion to heat the section of the tubular portion;

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 to form a neck portion between the receiving chamber and the second end portion;

pressing the first end portion and the second end portion together until an exterior surface of the tubular portion surrounding the collapsed section is level with a remaining exterior surface of the tubular portion; and

forming an opening in the second end portion, wherein forming the opening comprises simultaneously applying heat to a center portion of the second end and injecting air into an opening in the first end portion until the opening in the second end portion is formed.

2. The method of claim 1 wherein the neck portion comprises an opening that is narrower than an opening of the first end portion.

3. The method of claim 1 wherein an elongated vapor chamber is formed between the neck portion and the second end portion, the elongated vapor chamber having a length greater than a length of the receiving chamber, a third inner diameter that is equal to the second inner diameter and an outer surface with no grooves, recesses or other indentations.

4. The method of claim 1 wherein the opening in the second end portion is narrower than the opening of the first end portion.

5. The method of claim 1 wherein the air is injected into the opening in the first end portion at a pressure of 20 psi to 30 psi.

6. The method of claim 1 wherein applying the pressure comprises contacting the heated section of the tubular portion with a tool.

7. The method of claim 6 wherein the tool is pressed against the heated section of the tubular portion by a machine.

8. The method of claim 6 wherein the tool comprises a pointed end that is pressed against the heated section of the tubular portion.
