Definitions

  • This invention relates to a receptacle or container for containing contents and more particularly to a container or receptacle for containing milk, juice or other type of drink having a pour opening for permitting the contents to be discharged from the receptacle.
  • a receptacle or container for a drink which can prevent the deposition of dust and water, and which can be easily imparted with barrier properties.
  • a receptacle or container for a drink includes a cylindrical receptacle main body having an open upper end that is closed by a plastic lid provided with an opening for use in drinking. The opening is covered with an openable pull tab and the outer periphery of the lid is provided with a flange. A cover film is sealed to the flange to cover die lid.
  • a receptacle or container for a drink in another form of the invention, includes a cylindrical receptacle main body having an open upper end that is closed by a plastic lid provided with an opening for use in drinking.
  • the lid is provided with an upstanding flange that surrounds at least the opening in the lid.
  • a cover film is sealed to the flange to cover the lid. Since the cover film is sealed so as to cover the upper lid or the opening in the lid, the upper surface of the lid or the portion of the lid containing the opening is shielded from the outer atmosphere. Thus, there is no fear of deposition of dust or water on the upper surface of the lid, particularly in the area of the lid where the opening is located. Thus, the upper surface of the lid can be maintained clean until the opening is actually exposed.
  • the cover film having a relatively simple construction is formed of a film material also having oxygen barrier properties. This does away with the need for imparting barrier properties to the upper lid and the pull tab.
  • Fig. 1 is an exploded perspective view of a portion of a receptacle according to one embodiment of the present invention illustrating the receptacle main body, the lid, the pull tab and the cover film;
  • Fig. 2 is a perspective view of a portion of the receptacle shown in Fig. 1 with the cover film sealed to the lid;

  • e handle portion 33 of the pull tab 30 is caught by the flange 21 of die upper lid 20 as shown by die solid line in Fig. 3.
  • the pull tab used in the receptacle according to the present invention is not limited to die specific structure illustrated and described above.
  • Pull tabs having various other structures such as a structure in which a sheet-like pull tab is applied may be employed.
  • the cover film 50 may be formed of a relatively inexpensive material having no barrier properties.
  • the receptacle main body is not limited to a circular form as other shapes may be employed.
  • Figs. 4 and 5 depict die features associated widi d e lid and d e cover film.
  • diis alternative embodiment of die invention employs an upper lid 20 formed of a plastic material and a cover film 50 provided on and sealed to me upper lid 20.
  • the upper lid 20 is provided with an upwardly extending flange 21 arranged to surround the lid 20, and an opening 23 for use in drinking or otherwise discharging the contents from die receptacle.
