Description

Directly make the method for food containers with paper pulp

The present invention relates to a kind of preparation method of container, particularly directly make the method for food containers with paper pulp.

The now general used disposable lunch box of catering trade mostly adopts foam plastic product, and the unsuitable splendid attire heat of this lunch box food is placed the bad processing that pollutes the environment everywhere after especially using up.As adopt tub or carton, it is very numerous and diverse then to paste formality, costs an arm and a leg, also convenient inadequately.

The objective of the invention is to provide a kind of method of directly making food containers with paper pulp, it is simple that this legal system is made degree, the work efficiency height, and cost is low, uses the food containers of back not pollute the environment, and handles easily.

The object of the present invention is achieved like this: this method be with raw material paper pulp after container dilution is put in making beating, wire netting with identical with the food containers size shape is enclosed within on the vacuum forming mould, puts into the container of above-mentioned Sheng paper pulp then, with the mode of vacuumizing pulp liquor is extracted out again, in the vacuum forming drying machine, take off wire netting, with the former dry paper pulp pressing and forming that on wire netting, adheres to, dry, the demoulding, paper tire after the demoulding through surface treatment, gets product.

Advantage of the present invention is that production process is simple, and cost is low, and product is attractive in appearance, practical, heat-resisting, with after can burn, bury, food containers is easily by bacterial decomposition, so do not pollute the environment, handles useful health easily.

Particular content of the present invention is provided by following examples and accompanying drawing thereof:

Fig. 1 is a stereogram when spreading out with the I type lunch box that the present invention makes.

Fig. 2 makes I type lunch box schematic cross-section with the present invention.

Fig. 3 makes II type lunch box schematic cross-section with the present invention.

Fig. 4 is a production process schematic diagram of the present invention.

Describe in detail below in conjunction with accompanying drawing.

With reference to Fig. 4, method of directly making food containers with paper pulp of the present invention is to carry out according to following operation:

1) raw material paper pulp is put into beater and pulled an oar 3～4 hours, take out then, it is soaked to put into container, and paper pulp and water are stirred by 1: 50 weight ratio;

2) will with the food containers shape of doing, 100～200 order wire nettings that size is identical of drawing up, be enclosed within on the patrix or counterdie of vacuum forming mould, and put into the container that above-mentioned bubble has paper pulp in the lump;

3) with the paper pulp after soaked in the container, extract out with the mode of vacuumizing, making on the wire netting with thickness at last is the thick dry paper pulp of 2～6mm;

4) will move in the vacuum forming drying machine with the wire netting and the mould of paper pulp, take off wire netting, under temperature is 150～180 ℃ and pressure, pressing and forming, dry, the demoulding;

5) with the paper tire after the demoulding, the surface spray is if quilt is answered heat-resisting, nontoxic thin glue, the cured or aluminium foil layer of one deck, or the press polish of pressurizeing again, gets product.

With reference to Fig. 1,2, be the I type lunch box that makes by above-mentioned operation, loam cake 1 fuses with end box 2, is provided with at the edge of loam cake 1 to contain edge 3, can fasten the outer rim of end box 2 when making it be placed on the end box 2, in case the food that wherein holds leaks outside, and keeps health.

With reference to Fig. 3, be the II type lunch box that makes by operation of the present invention, be provided with outside continuous point-like or the strip edge 4 and hold edge 5 at the set upside that contains edge 3 of edge outside the loam cake 1, so that deposit a pair of chopsticks 6 betwixt in, thereby conveniently have a dinner.
