A lid that closes a mouth of a container is made of a material principally including a paper material. The lid includes a side wall that is fitted into the mouth of the container, and a top lid that is surrounded by the side wall. The top lid includes an inlet/outlet formation part that forms an inlet/outlet for an article stored in the container, and a temporary fixing part that temporarily fixes the inlet/outlet formation part to the top lid. This can achieve a lid that has satisfactory thermal insulation, can reduce leakage, is user-friendly, can reduce a manufacturing cost, and is conscious of environmental issues.

The present disclosure relates to a two-side adherable high-frequency induction heating container sealing member, the sealing member comprising: an upper layer that comprises a first thermal-adhesion sealing layer, a first aluminum foil layer, an intermediate base layer, a synthetic resin layer having tensile strength and hardness, and a first thermal-adhesion resin layer, which are successively formed from the top to the bottom, the upper layer having a preformed opening guide cut line-provided opening tab, a preformed opening guide cut strip, and a preformed thermal-adhesion sealing strip; and a lower layer that is formed beneath the upper layer and comprises a second aluminum foil layer and a second thermal-adhesion sealing layer, which are successively formed from the top to the bottom, wherein the first thermal-adhesion resin layer of the upper layer is integrated with the second aluminum foil layer of the lower layer through thermal adhesion.

The present disclosure relates to a transport closure (1) for use in a packaging container (10) for bulk solids. The transport closure includes a laminate of a first layer (2) and a second layer (3). The first layer (2) is delimited by a first layer peripheral edge (4) and the second layer (3) is delimited by a second layer peripheral edge (5). The second layer (3) comprises or consists of a weldable material and the first layer (2) has higher tear strength than the second layer (2). The first layer (3) is provided with a weakening line (6) defining a pull-tab (7) in the first layer (3) and having a first and a second base point (6a,6b). The base points (6a,6b) are arranged at a base end (7b) of the pull-tab (7), opposite to a gripping end (7a) of the pull-tab (7).

A closure body (40) is provided for installation with a liner membrane (52) on a container (44). The closure body (40) has a peripheral portion (74) for being mounted on the container (44) around an access opening (48), and a separable portion (82) that (i) is disposed laterally inwardly of the peripheral portion (74); (ii) is initially connected to the peripheral portion (74) by at least one frangible connection (86); and (iii) can be separated from the peripheral portion (74) upon breaking of the at least one frangible connection (86). The closure body (40) has an opening member (94) that is connected with the separable portion (82) to accommodate movement of the opening member (94) relative to the separable portion (82).
