Description

Papery food vessel with new structure

The utility model relates to the packaging for foodstuff field, more specifically to a kind of papery food vessel, especially relates to a kind of novel structure, amounts to the mode uniqueness and is applicable to the papery food vessel that large-scale machines is produced.

Early eighties, China has carried out reforms since the open door policy, national economy has obtained comprehensive development, living standards of the people improve rapidly, allegro life style of the thing followed and Updating of Consumption Ideas, making each city of China occur as emerging rapidly in large numbersBamboo shoots after a spring rain managing with the rice is the fast food industry of staple food.But the cutlery box that present fast food uses polystyrene, polypropylene and the polyvinylchloride of petrochemical by-product production to make in a large number.Consequent discarded cutlery box rubbish can not burn, and is difficult for degraded again and rots, and environment has been caused serious pollution.Even more serious is, is the poisonous germ in breeding place with remnant in such cutlery box, and again in large quantities, constantly corrosive ground and air have constituted threat to existent environment of people.

Along with improving constantly of human environment protection consciousness, more and more pay attention to ecological protection to the earth, decree, the rules of forbidding producing and use the package packing supplies that above-mentioned material makes have expressly been issued in many countries and regions.Can foretell that in the near future, in the world, this " white pollution " will begin to obtain basic improvement from the source.

People generally pay attention to environmental pollution this day by day during distinct issues, can expect very naturally replacing the plastic foam material that serves as the leading role at present with substitute.The product that present existing products has the paper matrix moulding to make, its advantage is that cost is lower, has certain waterproof, grease proofing and heat-insulating performance.But shortcoming is the sanitary measures complexity, and some indexs are difficult to reach requirement.And complex process, a large amount of discharge of wastewater is arranged, deflection is relatively poor; Another kind is that vegetable material adds the product that makes, and its advantage is aesthetic in appearance, and manufacture craft is simple.But it is long that shortcoming is a degradation time, and outward appearance and plastics are close, easily causes the phenomenon of mixing the genuine with the fictitious, and is difficult to management, and waste can not be recycled, and refuse relies on the natural conditions degraded, is easy to generate mould in the degradation process, and environment is still caused certain pollution; Also having a kind of is the full import pulp product that gets made of paper, and its advantage is that visual impression is preferably arranged, and is convenient to recycling.But shortcoming is the cost height, and market can't be accepted.

In order to comply with the development of food and fast food, utterly destroy " white pollution ", inventor of the present utility model has been developed into a kind of novel structure, amounts to the papery food vessel of mode uniqueness.This papery food vessel is made with ash end blank or coated duplex board with white back, and the size of cardboard is decided according to the size of required cutlery box.By its distinguished mode of amounting to, it is low to make it to have cost, advantage such as intensity is good, and resistance to pressure is strong, and can adapt to the demand of large automatic pipelining.Therefore, the purpose of this utility model is to provide a kind of novel structure, amounts to the mode uniqueness, is applicable to the papery food vessel that large-scale machines is produced.

The purpose of this utility model is achieved in that respectively having two of being separated by impression on four angles that make food vessel bottom surface cardboard amounts to joint face, this amounts to joint face can be leg-of-mutton, in the outer end of this joint face gluing and outwards amounting to, make itself and carton outer wall bonding.Make this papery food vessel and can use ash end blank or coated duplex board with white back.Describedly amount to operation and can on automatic moulding machine, carry out, satisfied the difficult problem that directly to use coil paper in the large automatic production process like this, traditional sheet cardboard cross cutting processing, the production technology of offhand have been replaced, successfully cut, answer film, moulding and printing in the papery food vessel are combined together, make the extensive automatic streamline operation of modernization of food vessel become possibility, improved capacity rating.In addition, because the sticking face that contains of food vessel does not contact with the inwall of food vessel, this has not only reduced the cost (need not reach food sanitation standard) of food vessel adhesives, and has guaranteed that food vessel inwall is not contaminated.This improvement of papery food vessel structure has also strengthened the intensity and the resistance to pressure of this vessel, has satisfied the demand that requires high-intensity food cutlery box on railway and the steamer.

Embodiment with reference to the accompanying drawings is described in detail the utility model.

Fig. 1 is for making the cardboard of papery food vessel;

Fig. 2 is the structural representation of this papery food vessel.

The cardboard of making the utility model paper container for food shown in Figure 1, cardboard can be adopted Use coated duplex board with grey back, also can adopt coated duplex board with white back. The size of cardboard is contained according to required food The size of device and deciding. The outside of cardboard is positive, and the front can be the color printing that is printed on various patterns Face; The coated surface of cardboard (inner face) is reverse side. Described cardboard comprises bottom surface 1, and capping 2 is at the end Face 3, back, the end 6, bottom side 4, the triangle that is formed by the branches such as line of weakness that carve in advance Joint face 5a, 5b, 5c and 5d are amounted in the end of (or other shape), lid side 7 and lid front 8. Bottom surface 1 connects with end front- back 3,6 and two bottom sides 4 by the line of weakness that carves in advance Connect, and end front- back 3,6 and two bottom sides 4 respectively by the line of weakness that carves in advance with The end, amount to joint face 5a, 5d and 5b, 5c connect, the indentation of back, the end 6 by carving in advance Line is connected with capping 2, and capping 2 line of weakness and two lid sides 7 by carving in advance Be connected front 8 and connect.

The manufacturing process of described paper container for food is: inwardly amount to folding the quarter along each line of weakness The trace line is fitted the reverse side of 5a and 5b and 5c and 5d, makes 5a and 5b and 5c and 5d Respectively positive bonding with bottom side 4 of part after the applying so just formed papery food Vessel.

Below in conjunction with embodiment the utility model is described in further detail, but should be appreciated that, these embodiment are just in order to illustrate the utility model better, and the utility model never is limited to these specific embodiments.Embodiment 1
