Abstract: Disclosed is a bottle used for a dispenser for dispensing oral cleaning liquid. The bottle comprises a bottle body capable of containing liquid; a bottle neck part formed at an upper part of the bottle body; a first cap engaged with an outer surface of the bottle neck part; and a second cap provided between the bottle neck part and the first cap and engaged at an upper end of the bottle neck part. The second cap is formed with a plurality of tear lines at an interval, which enable the second cap to be easily ruptured by an external force. A center of the second cap to which the tear lines are converged is formed with a recessed portion into which a protrusion provided to the dispenser is fitted.
Abstract: A method for fabricating a multi-layer film for vacuum packaging, comprises the steps of: supplying a gas-impermeable film to a cooling roll; supplying a sealing film to a nip roll having an embossed pattern; extruding a molten polymer material toward a gap between the gas-impermeable film and the sealing film, thereby forming a multi-layer preform having a structure of gas-impermeable film-polymer layer-sealing film; and squeezing the multi-layer preform by passing the multi-layer preform through a nip between the nip roll and the cooling roll, so that the gas-impermeable film, the sealing film, and the polymer material of the multi-layer preform are laminated on each other simultaneously while the sealing film and the polymer material are embossed by the nip roll and the cooling roll.
