Abstract

Abstract A straw is combined with a cup or cup lid to form a nestable and disposable liquid refreshment receptacle or cover therefor. The straw and cup or cup lid are integrally molded to form a one-piece member therefore do not require separate dispensing or subsequent assembly. The straw/lid and straw/cup combinations are made nestable for high density distribution and storage as required for high volume or fast food applications. The straw/lid includes a dual-taper upper drinking extension and a single taper lower liquid engaging member. A recess is formed between cylindrical walls forming the drinking extension into which the drinking extension of an adjacent straw/lid is matingly received or nested during stacking. Further, respective lower liquid engaging members are received with one-another to permit nesting. In similar manner the straw/cups are nestable. Each cup defines a longitudinal recess along its outer side to receive the integrally formed straw of an adjacent cup during stacking.

Claims Analysis

Total Claims: 6

Claim 1

Independent Claim 93 words

An integral lid and straw for a disposable drinking cup, the lid having means for attachment of the lid to a cup; the straw having a beverage engaging region extending below the lid and a user access region extending above the lid; means for nestably receiving the beverage engaging straw region of an adjacent integral lid and straw; means for nestably receiving the user access straw region of an adjacent integral lid and straw whereby a plurality of integral lids and straws may be nested in close relative proximity for high density packaging.

Claim 2

Dependent Claim 93 words

Claim 3

Dependent Claim 94 words

A lid for a disposable drinking cup including means for attachment of the lid to the top of a drinking cup, a straw integrally formed on the lid, the straw including a first portion extending below the lid for engaging the contents of the cup and a second portion extending above the lid permitting user accesss to the contents of the cup; means for nestably receiving the first and second straw portions of adjacent straws whereby a plurality of integral lids and straws may be nested in close relative proximity for high density packaging.

Claim 4

Dependent Claim 94 words

Claim 5

Dependent Claim 199 words

The integral lid and straw of claim 1 wherein the user access region includes concentric tapered inner and outer walls, the outer wall being integrally attached to the lid and extending upwardly therefrom and narrowing in diameter from its point of attachment to its maximum distal extension, the inner wall being integrally attached to the outer wall at said maximum distal extension of the outer wall, the inner wall extending downwardly, and narrowing in diameter, from said point of attachment to a point below the lid, the portion of the inner wall extending below the lid defining the beverage engaging region of the straw; the means for nestably receiving the user access region of an adjacent straw includes the interior volume space defined between the inner and outer concentric walls whereby the user access region of a lower adjacent straw may b received upwardly into said interior volume between the concentric walls; the means for nestably receiving the beverage engaging region of an adjacent straw includes the interior tapered volume space defined within the inner concentric wall whereby the beverage engaging region of an upper adjacent straw may be received downwardly into said interior volume of the inner wall.

Claim 6

Dependent Claim 114 words

The integral lid and straw of claim 3 including means for urging the lower distal end of the beverage engaging region of the straw into engagement with the sidewall of a cup placed therebelow, said means includes placement of the straw in off-set orientation on the lid in close proximity to the perimeter edge of the lid whereby the lower distal end of the beverage engagement region of the straw will be forced inwardly by the cup sidewall upon placement of a cup therebelow, said means further including the inner and outer walls of the straw which serve to generate an outward force biasing the straw against the cup upon said inward straw deflection.
