Definitions

  • the present invention relates to a cover of container made of plastic, more particularly to a cover of container, which its airtight power is increased and a soft molding material and a rigid molding material can be stuck to each other, so that after molding, the cover is to be made smooth and flat.
  • the prior art is represented as a container cover made by double injection molding method as shown in Fig. 6, which is that after the body (11) of the cap (10) is made at first, the part (10a) that is combined with the container (20) is made of a soft material on the outer border of the cap (10) by double injection molding method, which is formed the body (11), so that the combining part (10a) has a better airtight power by means of the soft viscosity.
  • the inside part of the combining part (10a) is coating-treated with a soft material, so that the coating-treated part (13) has a great airtight power due to the viscosity.
  • the coated- treated part is scaling after all.
  • the coating layer is formed inside part of the combining part (10a) by double injection molding method, so the said coating layer is protruded toward the top through the hole or the opening part on the cover, so the airtight power is improved and the appearance is excellent as well as the coating layer that is formed inside of the combining part (10a) may not be separated.
  • FIG. 1 is a perspective view according to the embodiment of the present invention
  • FIG. 2 is a perspective view showing the hole of the cover
  • FIG. 3 is a perspective view showing the opening part instead of the said hole
  • FIG. 4 is a sectional view showing the formation of the outer wall.
  • FIG. 4 A is a sectional view showing the formation of the inner wall
  • FIG. 5 is a perspective view showing the hole perforated on the cover of the container.

  • FIG. 7 is a sectional view showing the coating layer of the prior art
  • the present invention relates to a cover of container made of plastic, more particularly to a cover of container, which its airtight power is increased and a soft molding material and a rigid molding material can be stuck to each other, so that after molding, the cover is to be made smooth and flat.

Abstract

Usuellement, on doit utiliser des pressions et des torsions pour injecter un matériau assurant l'étanchéité d'un couvercle mince d'emballage. Selon l'invention, on peut arriver au même résultat sans pression ni torsion en recourant à une double injection, depuis le haut et depuis le bas, pour mettre en place le matériau d'étanchéité
