Abstract: Disclosed is a tray sealing apparatus for sealing a disposable tray with a thermoplastic sealing film. The tray sealing apparatus includes: a base body having a top surface and a tray reception cavity formed in the upper surface; and a heater unit for heating the sealing film that the sealing film adheres by fusion to the flange of the tray inserted in the tray reception cavity. The heater unit includes a principal surface with a predetermined width, and a thin strip-type electric heating element formed in a closed curve shape corresponding to the shape of the flange of the tray. When sealing the tray with the seal film by fusion, the peripheral surface of the electric heating element is disposed along the whole flange of the tray with the seal film being interposed therebetween so as to apply the heat generated by the electric heating element to the seal film.

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.
