The first seal (462) includes mating of thermoplastic-to-thermoplastic sealing surfaces of the body (101, 301) and lid (101, 120, 320) respectively. The second seal (464) includes mating of thermoplastic-to-elastomeric sealing surfaces of the body (101, 301) and lid (101, 120, 320), respectively, or of the lid (101, 120, 320) and body (101, 301), respectively.

A container includes a base, a cover and an intermediate part. The base includes a first room and a first lip extends from the open top of the base. The cover includes a second room and a second lip extends from the open bottom of the cover. The intermediate part includes a third room and a third lip extends from the open top of the third room. The cover is mounted to the base with the intermediate part located between the cover and the base. The cover seals the base and the intermediate part by one-time pressing action. The base includes at least one plate which is engaged with a recess formed to the outside of the second lip of the cover to secure the cover to the base.

It is desired to make an improved lid suitable for pails, overcoming the problem of existing complexities and leaks. The invention is achieved by a lid (300) having a lid skirt (320) provided with an inner collar (328) that engages an outer collar (222) of a sidewall (220) of a pail (200), the lid skirt (320) being provided with a fastening mechanism (330) for tightening the inner collar (328) around the sidewall (220) below the outer collar (222). Corresponding to the lid (300) a pail (200) is provided having a simplified structure that is supported mechanically by the lid (300). Furthermore, a thermally insulated compound pail is disclosed, the compound pail comprising a first inner pail (200) that is inserted into a second outer pail (200) such that a space (404) is formed between said pails (200).

At least some example embodiments relate to a container including a body and a lid. The body includes a base, a side wall, and an interior region at least partially defined by the base and the side wall. The lid includes a lid wall and a skirt that extends from a periphery of the lid wall. The skirt engages the body to retain the lid on the body. The skirt cooperates with the lid wall to define a cavity. The lid is formed from a laminate including a metal layer and a polymer layer coupled to the metal layer. The polymer layer is disposed inside of the metal layer with respect to the cavity. A portion of the body is disposed inside the cavity when the container is in a closed configuration. At least some example embodiments relate to a forming of manufacturing the lid.

A beverage product has a beverage container, a quantity of a beverage in the beverage container, a flexible, compressible plug sealing the beverage container, and a contiguous molded lid having a cylindrical upper portion with a top having a matrix of openings, a cavity in the upper portion below the top, the cavity open to the underside, a shoulder facing downward, and a descending skirt below the shoulder, the descending skirt separated by a plurality of vertical slots into a plurality of flexible tabs having each a lowermost, inwardly facing lip, the contiguous molded lid engaged to the beverage container by the flexible tabs.

A method of over-molding materials includes: providing a first material in a groove in a first portion of a mold such that only a single surface of the first material is exposed to a vacant portion of the mold; providing, via an injection molding process, a second material in a liquid form in the vacant portion of the mold adjacent to, and in engagement with, the first material; and allowing the second material to solidify and become directly coupled to the first material, thus forming a single component. The second material has one or both of a greater hardness when solidified than the first material and/or a higher melting temperature than the first material.

A large-caliber, hoop-free and well-sealed plastic barrel, including a barrel body with a rim portion and a cover. The rim portion is provided with a sealing ring, whose outer peripheral surface is a first sealing surface. An outer side of the barrel body is provided with an annular clamp ring, which is arranged below the sealing ring. The cover is provided with a sealing groove fitting the rim portion. An outer surface of an inner side wall of the sealing groove tightly fit an inner wall of the rim portion. An inner surface of an outer side wall of the sealing groove is provided with a second sealing surface in a seal fit with the first sealing surface. An outer peripheral surface of the cover is provided with a hook strip, whose inner side wall is provided with a flange to be clamped with the clamp ring.

A press-type cosmetic bottle has a bottle body and a bottle cap. The bottle body comprises a bottle base and a bottle interface which are integrated as a whole. The bottle cap comprises an outer cap, a connector connected to the outer cap, and a middle ring fixed on the connector. The outer cap is provided with a press hole, and a press block is provided in the press hole. The bottle interface is held by the middle ring so that the bottle body is tightly connected to the bottle cap, and thus the bottle cap is not easy to get loose under the impact of an external force. The middle ring is configured to be pressed by the press block to make the middle ring deform, so that the middle ring disengages from the bottle interface, thereby removing the bottle cap from the bottle body.
