PLASTIC CONTAINER
A plastic container includes a molded multi-layered structure defining an inner space therein and including a first molded layer surrounding the inner space and having an outer surface and an outer protrusion protruding outwardly from the outer surface, and a second molded layer surrounding and covering the outer surface of the first molded layer and formed with an outer through-hole. The outer protrusion of the first molded layer fills and seals the outer through-hole in the second molded layer.
1. Field of the Invention
The invention relates to a container, more particularly to a plastic container having a molded multi-layered structure.
2. Description of the Related Art
Conventional plastic containers made from melamine normally have only one color and a simple structure. As a consequence, the conventional plastic containers are not attractive.
SUMMARY OF THE INVENTIONTherefore, the object of the present invention is to provide a container that can overcome the aforesaid drawback associated with the prior art.
A plastic container according to the present invention comprises a molded multi-layered structure defining an inner space therein and including a first molded layer surrounding the inner space and having an outer surface and an outer protrusion protruding outwardly from the outer surface, and a second molded layer surrounding and covering the outer surface of the first molded layer and formed with an outer through-hole. The outer protrusion of the first molded layer fills and seals the outer through-hole in the second molded layer.
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings, of which:
Before the present invention is described in greater detail with reference to the accompanying preferred embodiments, it should be noted here in that like elements are denoted by the same reference numerals throughout the disclosure.
Referring to
In this embodiment, the molded multi-layered structure 10 further includes a third molded layer 4 surrounding the inner space 5, having an outer surface 41, and formed with at least one inner through-hole 42. The first molded layer 3 surrounds and covers the outer surface 41 of the third molded layer 4, and further has an inner surface 30 opposite to the outer surface 31, and at least one inner protrusion 33 that protrudes inwardly from the inner surface 30 and that fills and seals the corresponding inner through-hole 42 in the third molded layer 4.
In this embodiment, the outer and inner through-holes 22, 32, the outer protrusion 32, and the inner protrusion 33 have a flower shape, and the outer and inner through-holes 22, 42 are formed by male dies of the mold. The color of the third molded layer 4 is different from those of the first and second molded layers 3, 2.

Referring to
With the multi-layered structure 10 of the plastic container of this invention, the appearance of the plastic container can be considerably enhanced.
While the present invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
