Detailed description of the invention
Below, illustrate for implementing preferred embodiment of the present utility model.In addition, the embodiment below illustrated is the example that representational embodiment of the present utility model is shown, can not therefore scope of the present utility model be carried out reducing explanation.
Paper-made vessel of the present utility model has: the cup body parts using paper as basis material; And it is same using paper as the base plate part of basis material.
As the paper becoming basis material, as long as possess fastness to water and formability, just limit not processed especially.In addition, the laminated paper of the polyethylene film that the two sides lamination that also can be used in the paper becoming basis material has density different.
As laminated paper, include, for example out at Substance is 200 ~ 350g/m
2the single sided lamination of paper have the laminated paper of the LDPE of 10 ~ 30 μm, be 200 ~ 350g/m at Substance
2the single sided lamination of paper have the LDPE of 15 ~ 80 μm and have the laminated paper of LDPE, MDPE, HDPE of 15 ~ 40 μm in another single sided lamination.By using such laminated paper, thermal insulation paper-made vessel can be obtained.
The feature of paper-made vessel of the present utility model is, at least upper surface of flange is flatly processed.More specifically, it is characterized in that, curling flange is embedded in mould and applies pressure from above-below direction and be flatly shaped.
When carrying out curling shaping to flange, carry out curling shaping by heating, thus shaping is easily carried out.In addition, when carrying out curling shaping to the paper-made vessel be made up of laminated paper, preferably can not the temperature of degree of deposition heat with polyethylene film.
When being shaped when curling flange is embedded in mould, the thickness of the above-below direction of preferred flange is compressed to the thickness of 30 ~ 90% relative to the thickness of the above-below direction before processing, be preferably compressed to the thickness of 40 ~ 70% further.If bulk compressibility is less than 30%, then exists and can not obtain sufficient flange intensity or cause this problem of curling recovery.In addition, if bulk compressibility is greater than 90%, then exist do not have square shaping effect and aesthetic property does not change this problem yet.In addition, so-called bulk compressibility refers to, the ratio of the thickness of the above-below direction before and after processing.
