Abstract

Abstract A liquid container is made of a flexible film and a delivery device is securely attached to the container in such a way that a conduit portion of the delivery device extends into the interior of the liquid container. An opening is formed in the cylindrical wall of the conduit portion adjacent to the sealed top of the container. When the delivery device is used as a straw, the opening is closed with the wall of the container because of its flexibility. When the content in the container is poured into another liquid receptacle, the opening is used as an inlet so that the content of the container can be completely emptied.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 132 words
A liquid container comprising: a bag-shaped main body comprising a flexible film and having a sealed top; and a delivery device secured to said sealed top for allowing contents contained in the main body to pass therethrough, said delivery device comprising a mouth portion extending outside of the main body through which the contents contained in the main body can be sucked and discharged from the main body, a conduit portion extending from said mouth portion within the bag-shaped main body and through which the contents pass to the mouth portion, and a pair of ribs extending parallel to one another along said conduit member from a location adjacent the sealed top of the main body, said conduit portion having at least one opening extending radially therethrough between said pair of ribs.
Claim 2
Dependent Claim 132 words
A liquid container comprising: a bag-shaped main body comprising a flexible film and having a sealed top; and a delivery device secured to said sealed top for allowing contents contained in the main body to pass therethrough, said delivery device comprising a mouth portion extending outside of the main body through which the contents contained in the main body can be sucked and discharged from the main body, a conduit portion extending from said mouth portion within the bag-shaped main body and through which the contents pass to the mouth portion, and a pair of ribs extending parallel to one another along said conduit member from a location adjacent the sealed top of the main body, said conduit portion having at least one opening extending radially therethrough between said pair of ribs.
Claim 3
Dependent Claim 39 words
A liquid container as claimed in claim 1, wherein said ribs are diametrically opposed from one another on the conduit portion and extend therealong in a direction that is parallel to a central longitudinal axis of the conduit portion.
Claim 4
Dependent Claim 17 words
A container as claimed in claim 1, wherein said at least one opening has a slit-like shape.
Claim 5
Dependent Claim 35 words
A container as claimed in claim 3, wherein a semi-circular wall of the conduit portion extends between said pair of ribs and said at least one opening comprises two openings extending through said semi-circular wall.
Claim 6
Dependent Claim 349 words
A liquid container for containing contents which facilitates both the sucking of the contents therefrom and the pouring of substantially all of the contents therefrom when the container is inverted from a normal upright position, the liquid container comprising: a bag-shaped main body comprised of a flexible film and having a sealed top, the sealed top being at the top of the main body when the container is at said upright position; and a delivery device secured to the sealed top for allowing the contents contained in the main body to be sucked therefrom and for allowing the contents contained in the main body to be substantially completely poured therefrom when the container is inverted from said upright position, said delivery device comprising a mouth portion extending outside of the main body and substantially upward therefrom when the container is in said upright position, a conduit portion extending from the mouth portion into the main body and through which the contents contained in the main body pass to the mouth portion, the conduit portion having an axial opening extending therein open at one end thereof that is open to the mouth portion and through which the contents contained in the main body pass to the mouth portion when suction is applied to the mouth portion by the mouth of a person, and the conduit portion only having a second opening means extending radially therethrough adjacent the sealed top of the main body that is open to and communicates with said axial opening for allowing the contents contained in the main body to pass to the mouth portion and substantially completely discharge from the main body when the container is inverted from said upright portion, the second opening means being covered by the bag-shaped main body comprising a flexible film when the suction is applied to the mouth portion and the main body having the sealed top thereby collapses inward and over the second opening means to facilitate the passing of the contents through the axial opening of the conduit portion from the open end thereof to the mouth portion.
Claim 7
Dependent Claim 349 words
A liquid container for containing contents which facilitates both the sucking of the contents therefrom and the pouring of substantially all of the contents therefrom when the container is inverted from a normal upright position, the liquid container comprising: a bag-shaped main body comprised of a flexible film and having a sealed top, the sealed top being at the top of the main body when the container is at said upright position; and a delivery device secured to the sealed top for allowing the contents contained in the main body to be sucked therefrom and for allowing the contents contained in the main body to be substantially completely poured therefrom when the container is inverted from said upright position, said delivery device comprising a mouth portion extending outside of the main body and substantially upward therefrom when the container is in said upright position, a conduit portion extending from the mouth portion into the main body and through which the contents contained in the main body pass to the mouth portion, the conduit portion having an axial opening extending therein open at one end thereof that is open to the mouth portion and through which the contents contained in the main body pass to the mouth portion when suction is applied to the mouth portion by the mouth of a person, and the conduit portion only having a second opening means extending radially therethrough adjacent the sealed top of the main body that is open to and communicates with said axial opening for allowing the contents contained in the main body to pass to the mouth portion and substantially completely discharge from the main body when the container is inverted from said upright portion, the second opening means being covered by the bag-shaped main body comprising a flexible film when the suction is applied to the mouth portion and the main body having the sealed top thereby collapses inward and over the second opening means to facilitate the passing of the contents through the axial opening of the conduit portion from the open end thereof to the mouth portion.
