Abstract
Abstract A blow molded plastic container including a supporting member in the hollow space of the container extending completely across the hollow space and integral with the inside wall face of the body portion of the container at two spaced locations thereof to support the inside wall face. The body portion defines regions that comprise at least two adjoining lobes which form a handgrip. The method injection molds a preform containing an inner wall, blow molds the preform into the shape of a precursor having adjoining lobes separated by depressions, removes the precursor from the blow mold, and applies internal pressure into the precursor to form the precursor into its final shape including lobes.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
249 words
A blow molded plastic container which comprises: a neck portion defining an opening, a bottom portion and a body portion interconnecting the neck and bottom portions; wherein said neck, body and bottom portions define a hollow space closed at the bottom portion and open at the neck portion; said neck, body and bottom portions having an inside wall face and an outside wall face; at least one supporting member within the hollow space extending completely across the hollow space and integral with the inside wall face of the body portion at two spaced locations thereof to support said inside wall face; wherein the body portion defines regions that comprise at least two adjoining lobes, and with said lobes having two spaced depressions and a wall portion extending from one spaced depression to the other to form a wall portion having a shape of a handgrip, wherein at least one of said at least one supporting member in the hollow space extends from one of said spaced depressions to the other to support said spaced depressions, and wherein the spaced depressions have a base portion and the supporting member extends within the hollow space from said depression base of one of said spaced depressions to said depression base of the other of said spaced depressions; and wherein said wall portion of at least one of said lobes is blown in a mold to include segments releasable from said mold and deformed under internal pressure into the configuration of said handgrip.
Claim 2
Dependent Claim
249 words
A blow molded plastic container which comprises: a neck portion defining an opening, a bottom portion and a body portion interconnecting the neck and bottom portions; wherein said neck, body and bottom portions define a hollow space closed at the bottom portion and open at the neck portion; said neck, body and bottom portions having an inside wall face and an outside wall face; at least one supporting member within the hollow space extending completely across the hollow space and integral with the inside wall face of the body portion at two spaced locations thereof to support said inside wall face; wherein the body portion defines regions that comprise at least two adjoining lobes, and with said lobes having two spaced depressions and a wall portion extending from one spaced depression to the other to form a wall portion having a shape of a handgrip, wherein at least one of said at least one supporting member in the hollow space extends from one of said spaced depressions to the other to support said spaced depressions, and wherein the spaced depressions have a base portion and the supporting member extends within the hollow space from said depression base of one of said spaced depressions to said depression base of the other of said spaced depressions; and wherein said wall portion of at least one of said lobes is blown in a mold to include segments releasable from said mold and deformed under internal pressure into the configuration of said handgrip.
Claim 3
Dependent Claim
15 words
A container according to claim 1 wherein one of said lobes is a smaller lobe.
Claim 4
Dependent Claim
42 words
A container according to claim 2 wherein the smaller lobe includes said wall portion extending outwardly from said depressions and having substantially straight walls, said wall portion bulging outwardly to form arcuate segments when the container is filled with a carbonated beverage.
Claim 5
Dependent Claim
43 words
A container according to claim 3 wherein the adjoining lobes are of unequal size, and with the smaller lobe having said two spaced depressions with said wall portion extending from one spaced depression to the other to form a shape of said handgrip.
Claim 6
Dependent Claim
17 words
A container according to claim 4 wherein the handgrip is limited in extent to the body portion.
Claim 7
Dependent Claim
31 words
A container according to claim 5 wherein the supporting member which extends from one spaced depression to the other is limited in extent to the body portion and to the handgrip.
Claim 8
Dependent Claim
13 words
A container according to claim 1 wherein said handgrip has a curved configuration.
Claim 9
Independent Claim
