Abstract
Provided is the lid of a beverage container consisting of synthetic resin similarly to the container and constituted in such a manner that a straw can easily run through the lid, and the content, i.e. the beverage, does not leak even if shock is applied. The lid of a beverage container consists entirely of synthetic resin (R), wherein a substantially circular straw sticking region (20) is provided in a part (e.g. the center) of the lid, a plurality of cuts (Hc) having a depth equal to ¼-½ of the thickness of the synthetic resin material are formed in the straw sticking region (20), and the straw sticking region (20) has a diameter of 8.0 mm or less and the cut (Hc) has a length of 3.0 mm or less.
Claims6
A lid of a beverage container comprising:
- an entire lid formed from a synthetic resin;
- a substantially round straw puncture region disposed in a portion of the lid;
- multiple recessed areas formed in the straw puncture region to a depth that corresponds to ¼ to ½ of a thickness of the synthetic resin;
- and wherein
- a diameter of the straw puncture region is 8.0 mm or less;
- and
- a length of each of the recessed areas is 3.0 mm or less,
- wherein the multiple recessed areas include circular arch recessed areas, first linear recessed areas, second linear recessed areas and third linear recessed areas formed in the straw puncture region;
- the circular arch recessed areas define an imaginary circle in an outermost shell of the straw puncture region;
- the first linear recessed areas are formed in a region on an inside of an imaginary circle defined by the circular arch recessed areas, and define an imaginary equilateral triangle such that apexes are positioned outside of the imaginary circle and a center of gravity coincides with a center of the imaginary circle;
- second linear recessed areas extend from the center of the imaginary circle in a radial and outside direction of the imaginary circle;
- and
- third linear recessed areas extend parallel to the first linear recessed areas in a region between the first linear recessed areas and the second linear recessed areas.
