## Abstract

A production process of a bamboo bowl includes: cutting out arc-shaped bamboo strips on a bamboo board; splicing the bamboo strips into a bamboo ring; finally gluing several bamboo rings with gradually larger diameters on the bottom of the bamboo bowl successively to form a bamboo bowl billet, and making into a bamboo bowl after subsequent processings. The bamboo bowl made by the above production process includes a bamboo bowl bottom and bamboo rings superimposed on the bamboo bowl bottom; the bamboo ring consists of at least two arc-shaped bamboo strips, the diameters of the bamboo rings are gradually increased from the bottom up; the arc-shaped bamboo strips are fixed through adhesive, and the bamboo rings are also fixed through adhesive.

## Claims

### Claim 1

A production process of a bamboo bowl, comprising cutting out arc-shaped bamboo strips on a bamboo board; splicing the bamboo strips into a bamboo ring; finally gluing several bamboo rings with gradually larger diameters on the bottom of the bamboo bowl successively to form a bamboo bowl billet, and making into a bamboo bowl after subsequent processings.

### Claim 2

The production process of a bamboo bowl according to claim comprising the following steps:
(1) cutting the bamboo board: measuring a width of the bamboo board to determine the number of arc-shaped bamboo strips required to enclose one bamboo ring; calculating a radius of the arc-shaped bamboo strip; then cutting out the arc-shaped bamboo strips on the bamboo board according to this radius value;
(2) polishing arc-shaped bamboo strips: conducting polish on a sanding polisher according to prescribed specifications, such that the arc-shaped bamboo strips have equal thickness and width;
(3) combining into a bowl: combining the arc-shaped bamboo strips into a ring from small to large in radius using adhesive; then superimposing the arc-shaped bamboo strips from the bottom up in an increasing order in radius; the bamboo bottom being a round solid bamboo board; combining into a bamboo bowl billet finally;
(4) post processing: polishing an inter surface and an outer surface of the bamboo bowl billet into smooth curved surfaces; then performing carving and paint spraying.

### Claim 3 (depends on 2)

The production process of a bamboo bowl according to claim 2,
wherein one end of the arc-shaped bamboo strip is provided with a snap slot and the other end thereof is provided with a snap strip.

### Claim 4

A production process of a bamboo bowl, comprising bending a bamboo board into an arc shape in its width direction using a bamboo board bending technique; then cutting the arc-shaped bamboo board into arc-shaped bamboo strips in its length direction: splicing the arc-shaped bamboo strips into a bamboo ring; finally gluing several bamboo rings with gradually larger diameters on the bottom of the bamboo bowl successively to form a bamboo bowl billet, and making into a bamboo bowl after subsequent processings.

### Claim 5

A production process of a bamboo bowl, comprising gluing and superimposing successively a plurality of single bamboo boards, and bend molding the bamboo boards on a profiled make-up machine to make into an arc-shaped bamboo board; then cutting the arc-shaped bamboo board into arc-shaped bamboo strips in its length direction; splicing the arc-shaped bamboo strips into a bamboo ring; finally gluing several bamboo rings with gradually larger diameters on the bottom of the bamboo bowl successively to form a bamboo bowl billet, and making into a bamboo bowl after subsequent processings.

### Claim 6 (depends on 1)

A bamboo bowl made by the production process according to claim 1, comprising a bamboo bowl bottom and bamboo rings superimposed on the bamboo bowl bottom; the bamboo ring consists of at least two arc-shaped bamboo strips, the diameters of the bamboo rings are gradually increased from the bottom up.

### Claim 7 (depends on 5)

A bamboo bowl made by the production process according to claim 5, comprising a bamboo bowl bottom and bamboo rings superimposed on the bamboo bowl bottom; the bamboo ring consists of at least two arc-shaped bamboo strips, the diameters of the bamboo rings are gradually increased from the bottom up.
