Abstract
Abstract A method and apparatus for blow molding a wide mouth container wherein substantially the entire container is multiaxially oriented in its formation. The method and apparatus produce this container in effectively a one station operation without the need for high pressure injection molding platens. The apparatus is useful in making non-oriented articles as well. One such multiaxially oriented article that may be blow molded is a container having the configuration of an oil can.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
217 words
An apparatus for making a wide mouth container comprising means to injection mold a parison in a parison mold having a mouth portion and a body portion with said mouth portion having a greater diameter than said body portion, said parison mold comprising a movable mold means, a container mold, said parison mold comprising a cylindrical member and a core rod disposed in said parison mold so as to form a cavity there-between in which the parison is molded, and means to move said parison mold comprising means to move said cylindrical member along said core rod so as to permit the parison to be formed against the walls of the container mold, said cylindrical member being formed with a flange, and a flange surrounding said core rod and being opposed to said cylindrical member flange so as to form a parison portion interconnecting the parison mouth portion and the parison body portion, and means to blow mold the parison to form the container and means to move said parison mold and said cylindrical member flange to permit the parison to be blow molded against the inside of the container mold and the cylindrical member flange, further comprising means operably associated with said cylindrical member flange to provide fluid pressure between the cylindrical member and the parison.
Claim 2
Independent Claim
217 words
An apparatus for making a wide mouth container comprising means to injection mold a parison in a parison mold having a mouth portion and a body portion with said mouth portion having a greater diameter than said body portion, said parison mold comprising a movable mold means, a container mold, said parison mold comprising a cylindrical member and a core rod disposed in said parison mold so as to form a cavity there-between in which the parison is molded, and means to move said parison mold comprising means to move said cylindrical member along said core rod so as to permit the parison to be formed against the walls of the container mold, said cylindrical member being formed with a flange, and a flange surrounding said core rod and being opposed to said cylindrical member flange so as to form a parison portion interconnecting the parison mouth portion and the parison body portion, and means to blow mold the parison to form the container and means to move said parison mold and said cylindrical member flange to permit the parison to be blow molded against the inside of the container mold and the cylindrical member flange, further comprising means operably associated with said cylindrical member flange to provide fluid pressure between the cylindrical member and the parison.
Claim 3
Dependent Claim
20 words
The apparatus of claim 1, further comprising means operatively associated with the said cylindrical member to rotate the cylindrical member.
Claim 4
Dependent Claim
32 words
The apparatus of claim 1, further comprising means on at least one of said core rod and parison mold operatively associated with said mold to condition the parison to a desired temperature.
Claim 5
Dependent Claim
19 words
The apparatus of claim 3, further comprising means operatively associated with said core rod to rotate the core rod.
Claim 6
Dependent Claim
29 words
The apparatus of claim 4, wherein said means to blow mold the body portion further comprises means to form said interconnecting parison portion in contact with the container mold.
Claim 7
Dependent Claim
29 words
The apparatus of claim 5, wherein the means to blow the parison comprises a blowing fluid inlet formed between the core rod and the flange surrounding the core rod.
Claim 8
Dependent Claim
33 words
The apparatus of claim 3, wherein said conditioning means comprises means to flow a temperature conditioning fluid within the core rod, and means to flow a temperature conditioning fluid within the cylindrical member.
Claim 9
Independent Claim
242 words
An apparatus for making a wide mouth container comprising means to injection mold a parison in a parison mold having a mouth portion and a body portion with said mouth portion having a greater diameter than said body portion, said parison mold comprising a movable mold means, a container mold, said parison mold being positionable within said container mold, said parison mold comprising a cylindrical member and a core rod disposed in said parison mold so as to form a cavity there-between in which the parison is molded, and means to move said parison mold comprising means to move said cylindrical member along said core rod so as to permit the parison to be formed against the walls of the container mold, said cylindrical member being formed with a flange, and a flange surrounding said core rod and being opposed to said cylindrical member flange so as to form a parison portion interconnecting the parison mouth portion and the parison body portion and means to blow mold the parison to form the container and means to move said parison mold to permit the parison to be blow molded against the inside of the container mold, further comprising valve means operably associated and mounted with said cylindrical member to provide fluid pressure between the cylindrical member and the parison so that said valve means communicates between the space between the parison and the cylindrical member and the ambient environment outside the container mold.
Claim 10
