A container assembly maximizes lid-to-container retention or prevents inadvertent removal of a lid from a container, and includes a container and a lid. The container includes an upper rim and a container wall. The container wall includes a seam and a primary indentation. The indentation traverses the seam at an inner container surface in parallel relation to the rim. The lid comprising a rim-receiving groove, a lid wall, and a wall-to-groove resilient portion. The resilient portion extends intermediate the lid wall and the rim-receiving groove and is resiliently actuable intermediate a relaxed configuration and an actuated configuration. The resilient portion has at least one indentation-engaging portion. The rim-receiving groove receives the upper container rim, and the indentation-engaging portion engages indentation when in the actuated configuration. The rim-receiving groove and the indentation-engaging portion together lock the container lid to the container when in the actuated configuration for cooperatively maximizing lid-to-container retention.

Disclosed herein is an injection molded lid for use with a container. The lid includes a lid body and a securing member, respectively made of a first material and a second material. The lid body includes a cover portion and a flange portion disposed around the periphery of the cover portion. One side wall of the flange portion has one or more notches. The securing member includes at least one tab and a frame disposed at the flange portion. The tab extends from the top or bottom of the frame and covers the notch. Also disclosed herein is a container and lid assembly that includes a container and an above-described injection molded lid.

An injection molded lid (100) for use with a container, which includes a lid body (110) and a securing member (150). The lid body (110) includes a cover portion (120) and a flange portion (130). One side wall (134) of the flange portion has one or more notches (138). The securing member (150) includes a frame (152) and at least one tab (154). The tab (154) covers the notch. The securing member (150) provides extra fastening strength that prevents the spillage or leakage of the content within the container.

The invention relates to a lid for closing a container, preferably a cup, the lid being made from a paper- or a cardboard-material, wherein the lid comprises a topwall which covers the opening of the container and a sidewall directed at an angle relative to the topwall, wherein one end of the sidewall can engage sealingly with the top end of the container. The present invention further relates to a set comprising a lid and a container.

The present invention is directed to a lid for disposable or reusable plastic, paper, Styrofoam, bioplastic, recycled plastic cups. The lid comprises a body and a lip extending downwards along the perimeter of the body. The body and lip sealably crimp over the cup. A conical shaped spout continuous with the body of the lid protrudes upwards. The spout is specifically shaped and sized for allowing drinking from the cup with or without the use of a straw.

A lid-to-container locking combination maximizes lid-to-container retention and includes a container and a container lid. The container includes an upper container rim and a container wall. The container wall includes a radially outwardly extending indentation or groove located in inferior adjacency to the upper container rim at an inner surface thereof. The container lid includes a rim-receiving groove, a lid wall, and a wall-to-groove resilient portion. The resilient portion traverses a structural distance between the lid wall and the rim-receiving groove and is resiliently actuable intermediate a relaxed configuration and an actuated configuration. The resilient portion includes a radially outer indentation-engaging portion. The rim-receiving groove receives the upper container rim, and the indentation-engaging portion engages the radially outwardly extending indentation when in the actuated configuration. The rim-receiving groove and radially outer the indentation-engaging portion together lock the container lid to the liquid container for cooperatively maximizing lid-to-container retention.

A lid made from a paper material or a paper-like material for a beverage cup, which lid is constructed from a lid-plate element and a wall element and which offers below a lid plate which is formed by the lid-plate element a space for receiving components of a beverage which protrude beyond the cup.

A container includes a container body and a lid, which has an outer lid wall portion surrounding a central portion. The outer lid wall portion provides a lid-side sealing surface, which engage with body-side sealing surface, when the lid is applied to the container body to close the container. The container further includes a securing ring inserted within the outer lid wall portion. The securing ring having a lower portion and an upper flange portion extending from the lower portion at an acute angle () of less than 80 from vertical.

Disclosed is a beverage cup lid, in which the beverage cup lid (A) is coupled to a beverage cup (C), and is provided with a dispensing opening and a vent hole, the beverage cup lid including: a lid main body (10) including an engaging groove (11) provided at an edge of the lid main body to be engaged with an engaging protrusion (31) provided at an upper portion of the beverage cup (C), a dispensing opening (12) configured to be open upward at an upper portion of the lid main body, with a cap (13) being attached thereto, and a first vent hole (17) formed at an upper center of the lid main body to allow outside air or inside air of the beverage cup (C) to flow inside and outside the beverage cup (C), wherein the lid main body (10) is provided with a spiral groove portion (15).

A one-piece drink-through cup lid with a straw section includes a conic section and a detachable tube section. The conic section is axially protruding at a center of the cup lid and forming a rim at a top surface of the conic section. The detachable tube section is axially protruding from the rim of the conic section with a closed surface at a top thereof and an annular tear line at a bottom periphery thereof. The conic section and the tube section are formed in one-piece to ensure the cup lid is fully closed and sealed for practical use, and when the tube section is removed by manually tearing along the tear line, a through hole is formed at a top of the conic section so as to form a conic straw section for easily consuming the drink.
