Description

Bamboo container and manufacture method thereof

(1) technical field

The present invention relates to a kind of packing container (as the containers of using on the dining table such as dish lunch box) manufacturing technology, particularly a kind of have an environment protection significance can disposable bamboo (bamboo shoot) shell container and manufacture method thereof.

(2) background technology

Existing disposable 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 mostly can't be dissolved in the natural environment state automatically, thus the white pollution that causes 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 excessively, and the appearance colour dullness of container does not have the natural texture pattern, product specification is low, also is difficult to form large-scale production at present.In addition, it is that material is made environment protection type disposable type packing container (as service plate lunch box etc.) that the contriver who has has proposed with bamboo thin slice or paulownia thin slice, 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, drawing materials does not influence the environmental ecology balance, can burn or decompose, fully compliance with environmental protection requirements.Its unique shortcoming is to add to want man-hour earlier continuous bamboo thin slice (or paulownia thin slice) to be peeled off in ring (or paulownia wood) cutting (around cutting), and processing step is comparatively complicated, and it is higher that requirements for quality is peeled off in cutting.In addition, also finding no the people at present utilizes the bamboo shell (or claiming Compositions of Bamboo Shoot Shell) that comes off in a large number in the bamboo grove to report for the pertinent literature of manufacture of materials disposable packaging container.

(3) summary of the invention

The purpose of this invention is to provide a kind of is environment protection type disposable container and the manufacture method thereof that main material is made with bamboo shell (or claiming Compositions of Bamboo Shoot Shell), it can effectively solve environmental issue, and accomplished to make the best use of everything, not only the firm toughness of product is good, appearance also has splendid natural fiber lines, gives the sensation of expensive goods.

The present invention realizes with following technical scheme, the wall of this environment protection container is to make (annotate: the bamboo shell here is meant one deck parcel shell that the outside face that is wrapped in ring (or bamboo shoots) in the bamboo developmental process comes off naturally) by one or more pieces bamboo shell materials at least, when wall of a container is by the bamboo shell material more than two or two when hot-forming, the fiber grain of every adjacent two bamboo shells trend is that row or the superimposed gummed of vertical out-fall of beginning to rehearse interlaced with each other forms.Can on intensity, complement one another like this, increase toughness intensity, be difficult for breaking.

When specific design was made, in order to improve the intensity of container, the present invention was adding the supporting material of compositions such as can adding one deck synthetic resin or cardboard paper pulp, sticker man-hour between adjacent two bamboo shells.

In addition, can be the material that sprays paint that spraying last layer in bamboo shell surface plays reinforcing effect also, with further raising intensity at the container wall.

The present invention uses when one or more pieces bamboo shell materials are made the environment protection type disposable container at least, the processing step of its production mainly comprises as follows: get the raw materials ready---being shaped to plane (smooth)---coating viscose glue, and the pressing of multi-disc bamboo shell formed thick bamboo shell sheet---add water wet soft (with brush wipe wet or spray wet) bamboo shell surface (forming one deck water film) is---hot-forming---after taking out container (membrane) spray drying from hot press is finished product.

The present invention can add an amount of bactericidal agent and anti fouling composition on bamboo shell surface when adding the wet soft bamboo shell surface of water (or claiming the water film to form) process, can effectively prevent the bacterium intrusion like this, and can keep anticorrosion fungi-proofing performance for a long time.

The present invention also can be according to different splendid attire objects, and when only needing the container of monolithic bamboo casing forming, its processing step mainly comprises: get the raw materials ready---is shaped to plane (smooth) and---gets finished product after adding---hot-forming---the depanning spray drying in the wet soft bamboo shell surface of water.

The present invention can be before or after the hot-briquetting modeling process step be bonded with synthetic resin, paper (plate) or sprays paint and wait supporting material in the wherein one side of bamboo shell, multi-disc bamboo shell is adhered be overlapped into the higher thick bamboo shell of a slice intensity.

The present invention's bamboo shell container disposable uses up incendivity and handles, or also decomposition is rotten easily in natural environment behind the landfill, does not produce problem of environmental pollution, and can accomplish salvaging.Not only product strength height, toughness are good in addition, and the natural fiber lines on container bamboo shell surface produces the aesthetic appearance decorative pattern allows the people feel good, and product has feeling of high class, can be made into high-grade meal basin plate, snack box food box etc.

Below in conjunction with production instance bamboo shell container of the present invention and manufacture method thereof are described further.
