Abstract

The present invention relates to a synthesized food vessel made of bamboo (wood) slices and corn husk slices and a production method thereof. The vessel is formed by the method that the materials of at least one bamboo (wood) slice and one corn husk slice are flattened, coated with viscose, superposed and pressed in a heating way. The production method comprises the steps that materials are prepared, materials are cut to form sheet shapes according to needed size, the base materials of the synthesized vessel made of the bamboo (wood) and the corn husk are formed by the flat press and the press in a heating way after the materials are coated with viscose, and the base materials are put into a hot mold having an edging knife to be pressed and to be synthesized once to form the vessel after both faces of the base materials are sprayed with water. The present invention has the advantages that the cost of a disposable food vessel made of bamboo (wood) is reduced in a vast scale, the food vessel can be used for replacing a plastic bag having the defect of 'white pollution ', and the problem that a vessel made of wood is easy to leak is thoroughly solved.

Description

Bamboo wood chip, shuck sheet purified diet container and manufacture method thereof

The present invention relates to a kind of food container (as tableware and supermarket with pallet etc.), particularly a kind of have environment protection significance can disposable bamboo wood chip, shuck sheet purified diet container and manufacture method thereof.

Existing disposable food container; lunch box or other packing containers made if any synthetic resin and foamed plastic; promptly abandon after disposable the using up, because of material therefor can't be degraded in the natural environment state automatically, thereby " white pollution " that cause adverse environment to protect.In order to alleviate environmental pollution, proposed at present to replace with paper container or decomposable plastics tableware, its weak point is that cost is higher, invest excessive, and container appearances dull coloring, there is not the natural texture pattern, product specification is low and can not all degrade etc., and in addition, it is that material is made environment protection type disposable type food container (as service plate that existing people proposes with bamboo thin slice or wooden thin slice, lunch box etc.), this toughness of products is preferable, outward appearance also has the good-looking fiber grain of nature, and can make full use of short bamboo resource in growth period, and drawing materials does not influence the environmental ecology balance, can burn or degrade, fully compliance with environmental protection requirements.Its unique weakness is: the bamboo and wood tablet quality is had relatively high expectations, and cost still can not be compared with the foamed plastic container.Also find no the people in addition at present and utilize shuck sheet and bamboo wood chip to synthesize, make the pertinent literature report of food container.

The purpose of this invention is to provide a kind of bamboo wood chip, shuck sheet purified diet container and manufacture method thereof, it had both kept whole advantages of the wooden food container of bamboo, the cost of this container is declined to a great extent, also make material source abundanter, the more important thing is that having solved the wooden food container of bamboo particularly is the crux problem of the main food container easy to leak made from the wood chip.

The objective of the invention is to be achieved through the following technical solutions, this wall of a container is by bamboo wood chip material (at least one) and superimposed the making of shuck sheet (at least one) material, here the bamboo wood chip of the indication thin slice that to be the former material of a kind of bamboo wood form through rotary-cut or slicing, its single-sheet thickness is no more than 0.4mm, and length is decided on the container size.Here the shuck sheet of indication is meant the shell that is wrapped in the corn ear surface, through cleaning, smooth, dry, the shell sheet that forms of shearing.When specific design is made, when wall of a container is by the bamboo wood chip more than and the shuck sheet more than when synthetic, adjacent bamboo wood chip and shuck sheet should move towards interlaced with each other or vertical out-fall by its fiber grain, so more can increase the strength and toughness of container, make it be difficult for breaking, have as manufacturing that the disposable lunch box renovated can (patent No.: ZL012062871) scheme implementation of design can obtain identical with it effect in " the Foodstuff bamboo packing gold that lid is arranged " by my another patent.

To clean, smooth, dry, shear the two-sided or single face gluing of shuck sheet that the back forms (but can the also roller bearing gluing of manual brush coating), this viscose glue should be nontoxic, the glue that can adapt to technological requirement of the present invention, the shuck sheet of last glue is placed between two bamboo wood chips, or on bamboo wood chip, still be stacked alternately as the need multilayer by the interval, it is superimposed after flat hot pressing forms the bamboo wood chip, the base material of shuck food container, with substrate surface with suitable high-temperature steam fog softening after, through hot compression molding (mould belongs to a kind of compound die that edge-trimming cutter is arranged), again through the sand limit, packing, the sterilization warehouse-in.

Below in conjunction with production example bamboo wood chip of the present invention, shuck sheet food container and manufacture method thereof are described further:

Fig. 1 is the process flow chart that the present invention adopts two bamboo wood chips, a shuck sheet to carry out processing and manufacturing.Adopt two shuck sheets, a bamboo wood chip or other process that is combined into the Xingqi manufacturing identical with it.

Fig. 2 is the bamboo wood chip through hot compression molding, the disk-like structure figure of shuck food container.

1. bamboo wood chips wherein; 2. shuck sheet; 3. synthetic base material; 4. steam sprays; 5. go up shaping mould; 6. compacted under mould; 7. finished product.

Claims

1. the synthetic food container of bamboo wood chip and shuck sheet is characterized in that this wall of a container is to be made by at least one bamboo wood chip and a shuck sheet or many bamboo wood chips and many shuck sheet material.

2. food container according to claim 1 is characterized in that wall of a container by at least one bamboo wood chip and synthetic manufacturing of shuck sheet, and every adjacent two fiber grain trend is that discharging interlaced with each other or the superimposed gummed of vertical out-fall form.

3. according to the manufacture method of the described bamboo wood of claim 1, shuck sheet purified diet container, it is characterized in that this wall of a container is by at least one bamboo wood chip and a shuck sheet or many bamboo wood chips, many shuck sheet material are synthetic to be made through hot pressing, and its processing step mainly comprises: get the raw materials ready, scale, coating viscose glue, the synthetic substrate of flat hot pressing, add the two surfaces of the wet soft base plate of water, hot compression molding, sand limit, packing, sterilization and put in storage.
