Abstract
A freezable reusable bottle having a body and a cap engaged with the body. The body includes a container portion and a neck portion extending from the container portion. The container portion includes a plurality of ribs extending along a longitudinal axis of the reusable bottle. The cap removably engages with the neck portion of the body. The body includes a polymer composition of about 85 to 90 percent of polypropylene (PP) and about 10 to 15 percent of an SEBS additive. The bottle may be frozen when filled with a liquid, with the ribs accommodating expansion of the contents during freezing, and the additive providing impact resistance accommodating the rigid frozen contents.
Claims14
A freezable reusable bottle comprising:
- a body comprising a container portion and a neck portion extending from the container portion, wherein the container portion comprises a plurality of ribs having a length extending along a longitudinal axis of the reusable bottle;
- and
- a cap engaged with the neck portion of the body,
- wherein the body comprises a polymer composition of about 85 to 90 percent of polypropylene (PP) and about 10 to 15 percent of styrene-ethylene-butylene-styrene (SEBS);
- wherein the plurality of ribs comprises a wave shaped structure of alternating longitudinal troughs and longitudinal crests around a circumferential surface of the container portion,
- wherein at least a portion of the plurality of ribs have longitudinal troughs and longitudinal crests of equal length that extend from a bottom of the bottle through a base portion through a waist portion to a top portion of the container portion;
- wherein the top portion and the bottom portion converge at the waist portion and the waist portion has a first cross-sectional area that is smaller than a respective cross-sectional area of each of the top portion and the bottom portion, thereby each longitudinal trough and longitudinal crest has a wave shape along the length thereof having a first crest at the top portion, a trough at the waist portion, and a second crest at the base portion;
- and
- wherein each longitudinal crest protrudes outward and has a first width at the waist portion that is smaller than a second width at the top portion, thereby defining a grip portion for a user at the waist portion having a decreased contact surface area;
- wherein a linear distance between immediately neighboring longitudinal crests progressively decreases from the waist portion toward both the top portion and the base portion of the container portion.
A freezable reusable bottle comprising:
- a body comprising a container portion and a neck portion extending from the container portion, wherein the container portion comprises a top portion, a waist portion, and a base portion, and comprises a plurality of ribs extending in a direction linearly aligned with a central longitudinal axis of the reusable bottle;
- and
- a cap engaged with the neck portion of the body,
- wherein the body comprises a polymer composition consisting essentially of 85 to 90 percent of is polypropylene random copolymer (PPRC) or polypropylene block copolymer (PPB) and 10 to 15 percent of styrene-ethylene-butylene-styrene (SEBS);
- wherein the plurality of ribs, in a transverse cross-section through the waist portion, have a corrugated structure defining at least a portion of the exterior circumferential surface of the bottle, and, in a direction parallel to the central longitudinal axis of the bottle, the entire corrugated structure has a wave form having a trough at the waist portion;
- wherein a linear distance between immediately neighboring crests progressively decreases from the waist portion toward both the top portion and toward the base portion of the container portion.
