Abstract

The utility model belongs to the household goods, in particular to a three layer co-extruding directly sucking plastic forming environment protection tableware, comprising a box cover (1), a box body (3), a lock ear (4) and an insert ear (5). The box body (3)and the box cover (1)are adhered together by three layers of an A layer (6)made of the polypropylene, a B layer made of the talcum powder or the calcium carbonate, and the amidon, and a C layer (8)made of the leftover materials after the A layer (6), the B layer (7)and the C layer (8)are synthesized. The PP of the tableware (A layer) is contacted with the contact, and the sanitary and the safety of the product are ensured; the tenacity, the tensile strength and the impact strength of the PP are good; the PP is suitable for the flexible surface, and has good degradability, and reduces greatly the product cost; the leftover material can be optionally colored, which increases the aesthetic sense; simultaneously, the cost is also reduced; the abandoned tableware can be recycled to be utilized to make into the flower bowl, the clothe hanger, etc. The resource is saved, and both sides of the box body are provided with box ears, which facilitates the hand taking.

Description

Three-layer co-extruded direct plastics sucking moulding environmental protection food and drink tool

Technical field

The utility model belongs to daily necessities, particularly a kind of three-layer co-extruded direct plastics sucking moulding environmental protection food and drink tool.

Technical background

At present, the disposable lunch-box that uses on the China market, bowl, dish, cup, dish all be utilize polystyrene (PS) as material under molten condition, be squeezed into the sheet material plastics sucking moulding, its shortcoming is not degrade, and difficult the recovery caused serious white pollution to environment, can not be painted, hand is taken inconvenient.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, provide a kind of can degraded, can shades of colour, hand is taken three-layer co-extruded direct plastics sucking moulding environmental protection food and drink tool easily.

The technical scheme that the utility model technical solution problem adopts is: a kind of three-layer co-extruded direct plastic uptake environmental protection food and drink tool of being made up of lid, box body, lock ear and slotting ear, be characterized in the A layer that box body, lid are made by polypropylene (PP), the C layer that the laminated one-tenth leftover pieces of B layer, A, B, the C that talcum powder or calcium carbonate, starch are made are made, three layers bond together; A box ear is established at box body, lid two ends.

The beneficial effects of the utility model are: the PP of this food and drink tool (A layer) contacts with food, has guaranteed the safe and sanitary of product; The toughness of PP, hot strength and impact strength are good, suitable submissive surface, degradability is good, discarded back cracked efflorescence in 2,3 months in natural environment, weight average molecular weight descends more than 80%, degradation product is the lower-molecular substance of environmental sound, and product quality meets the regulation among the standard GB 18006.1-1999 fully; The B layer accounts for 70% of total thickness, is guaranteeing to greatly reduce the cost of product under the product quality premise; The leftover pieces of C layer can be painted arbitrarily, increased aesthetic feeling, also reduced cost simultaneously.The discarded also recyclable utilization of food and drink tool is made as flowerpot, clothes hanger etc., saves resource, and the box body both sides are provided with the box ear, make things convenient for hand to take.
