A tamper-indicating and child resistant cap and container assembly, comprising a cap comprising: a cap top wall; a cap skirt having an inner wall which is at least partially threaded, and an outer wall having at least one squeezing location; at least one tamper-indicating band frangibly connected to a free end of the cap and having defined therethrough an opening; at least one tongue extending from the free end of the cap skirt which circumferentially spaced from the at least one squeezing location. The container has an open end and a neck, an outer wall of the neck being at least partially threaded and configured to cooperate with the at least partially threaded inner wall of the cap; and at least one protrusion extending from the outer wall of the container neck and configured to be received in the opening of the at least one tamper-indicating band.

A child resistant bag includes: a bag body formed by a front film and a back film adhered together; wherein a tear strip is provided on the front film; a sealing device with a child resistant function is provided on an internal face of the bag body, which comprises a first protective sheet adhering to an upper side or a lower side of the opening and a patch covering the first protective sheet; at least one pair of strip fasteners is correspondingly provided on the patch and an internal face of the front film; the first protective sheet covers the opening and extends to an adhering position of the patch. The strip fasteners on the bag body are covered by the patch, which facilitates the filling of the child resistant bag, thereby improving the filling efficiency.

A sealing cap, which engages a neck of a bottle, including a top wall from which extend a sidewall and a sealing skirt. The sidewall includes a cap thread to be screwed onto a neck thread of the neck of the bottle around a screwing axis. The sealing skirt includes an inclined sealing surface to be pressed against a corresponding surface of the neck on an opposite side from the surface including the neck thread, upon screwing the cap thread onto the neck thread. The inclined sealing surface is formed by a wall of the sealing skirt surrounding a cavity. An inclination angle between the inclined sealing surface and the screwing axis is between 7 and 25. An axial length of the cap thread, taken parallel to the screwing axis, is higher than or equal to 1.5 times a pitch of the cap thread.
