Abstract

Abstract A device for controllably retaining liquid in and releasing liquid from a squeeze deflectable hollow container having a tubular neck defining a rim, about a mouth defined by the neck, incorporates a seal strip bonded to the rim about the mouth to extend over the mouth and block discharge of liquid from the container via the mouth. The strip is characterized as releasing from the rim in response to manual squeezing of the bottle and its liquid contents when the bottle is inverted, causing the contents to increasingly press against the strip; and a holder tab is carried by the strip and attached to the neck so as to retain the strip to the neck after it releases from the rim.

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 135 words
A device for controllably retaining liquid in and releasing liquid from a squeeze deflectable hollow container having a tubular neck defining a rim, about a mouth defined by the neck, comprising (a) a non-frangible seal strip releasably bonded to said rim about said mouth to extend over the mouth and block discharge of liquid from the container via said mouth, said strip characterized as releasing from said rim in response to internal pressurization of said container by manually squeezing the container and its liquid contents when the container is inverted, causing said contents to increasingly pressure against the strip to sever its bond from the rim, (b) and a holder tab carried by the strip and attached to the neck so as to retain the strip to the neck after it releases from the rim.
Claim 2
Independent Claim 135 words
A device for controllably retaining liquid in and releasing liquid from a squeeze deflectable hollow container having a tubular neck defining a rim, about a mouth defined by the neck, comprising (a) a non-frangible seal strip releasably bonded to said rim about said mouth to extend over the mouth and block discharge of liquid from the container via said mouth, said strip characterized as releasing from said rim in response to internal pressurization of said container by manually squeezing the container and its liquid contents when the container is inverted, causing said contents to increasingly pressure against the strip to sever its bond from the rim, (b) and a holder tab carried by the strip and attached to the neck so as to retain the strip to the neck after it releases from the rim.
Claim 3
Dependent Claim 39 words
The device of claim 1 wherein said strip is in the form of a disc, and said tab is integral with the strip to extend downwardly from a plane defined by the strip and adjacent said neck outer side.
Claim 4
Dependent Claim 48 words
The device of claim 1 including said container, which consists of molded plastic, containing said liquid, the container having a cap thread connected to said neck, the neck having a portion to which the tab is bonded, said portion having a reduced radial dimension relative to said threading.
Claim 5
Dependent Claim 21 words
The device of claim 1 wherein said strip consists of one of the following: (a) fabric (b) metal foil (c) plastic
Claim 6
Dependent Claim 36 words
The combination that includes the device of claim 1, the container associated therewith, and a cap on the container extending over said strip and said tab, and an interior seal on the cap engaging said strip.
Claim 7
Dependent Claim 39 words
The combination of claim 1 wherein the strip is bonded to only the outer portion of the rim, so that liquid may initially penetrate between the inner portion of the rim and the strip as the container is inverted.
Claim 8
Dependent Claim 64 words
The device of claim 1 wherein the strip has a first plastic sealing adhesive on one side thereof facing the rim and adapted to rigidly adhere to the container material, and also including a second adhesive applied between the rim and said first adhesive to decrease the adherence of the strip to the rim, while allowing rigid adherence of the tab to the neck.
Claim 9
Dependent Claim 43 words
The combination that includes the device of claim 1, the container associated therewith and having an outer side wall, and a cap on the container and having an inner wall engaging the tab and urging the tab against the container outer side wall.
Claim 10
Dependent Claim 63 words
The device of claim 1 wherein said rim has first and second sections, the second section having varying width along its length and the first section being C-shaped and having substantially uniform width along its length, said uniform width being less than the width of the second section along the major length of the second section, the tab bonded to said second section.
Claim 11
Dependent Claim 12 words
The device of claim 9 wherein said second section has sector shape.
Claim 12
Dependent Claim 32 words
The combination of claim 9 wherein the strip is anchored to the neck via a recess sunk in said second section of the rim, the strip having an anchor in said recess.
Claim 13
Independent Claim 141 words
The method of controllably retaining liquid in and releasing liquid from a squeeze deflectable hollow container having a tubular neck defining a rim, about a neck mouth, and employing a non-frangible seal strip and a holder tab carried by said strip, that includes: (a) bonding the seal strip to said rim said about mouth to extend over the mouth and block discharge of fluid from the container via said mouth, said strip bond characterized as releasing from said rim in response to internal pressurization of said container by manually squeezing the container and its liquid contents when the container is inverted, causing said contents to increasingly press against the strip to sever its bond with the rim, (b) and also bonding said tab to said neck so as to retain the strip to the neck after it releases from the rim.
Claim 14
Independent Claim 141 words
The method of controllably retaining liquid in and releasing liquid from a squeeze deflectable hollow container having a tubular neck defining a rim, about a neck mouth, and employing a non-frangible seal strip and a holder tab carried by said strip, that includes: (a) bonding the seal strip to said rim said about mouth to extend over the mouth and block discharge of fluid from the container via said mouth, said strip bond characterized as releasing from said rim in response to internal pressurization of said container by manually squeezing the container and its liquid contents when the container is inverted, causing said contents to increasingly press against the strip to sever its bond with the rim, (b) and also bonding said tab to said neck so as to retain the strip to the neck after it releases from the rim.
Claim 15
Dependent Claim 38 words
The method of claim 12 that also includes filling liquid into the container, and attaching a sealing cap to the neck so that the cap engages only the top of the strip, in spaced relative to the tab.
Claim 16
Dependent Claim 27 words
The method of claim 12 including said (b) step including bonding the tab to the outer side of the container neck, below the level of said rim.

Claim 18
Dependent Claim 17 words
The method of claim 10 including filling liquid in the form of engine oil into said container.
Claim 19
Dependent Claim 68 words
The method of claim 12 wherein said rim is provided in the form of first and second sections, the second section having varying width along its length and the first section being C-shaped and having substantially uniform width along its length, said uniform width being less than the width of the second section along the major length of the second section, the tab bonded to said second section.
Claim 20
Dependent Claim 19 words
The method of claim 17 wherein said container is molded to form said second section to have sector shape.
