Tray

Abstract

The present invention provides a tray including a body. The body includes an outer edge surface, a center hole, a plurality of inner cutting grooves, and a plurality of outer cutting grooves. The center hole penetrates a center of the body to form an inner edge surface spaced apart from the outer edge surface. The inner cutting grooves are formed on the body and they extend from the inner edge surface to the outer edge surface, respectively. The outer cutting grooves are formed on the body and are respectively disposed between the inner cutting grooves, and the outer cutting grooves extend from the outer edge surface to the center hole, respectively. The body can be stretched along the inner cutting grooves and the outer cutting grooves to make a space formed by the center hole and the inner cutting grooves larger and to change an area of the body.

What is claimed is: 
     
         1 . A tray system, comprising:
 a body including:
 an outer edge surface; 
 a center hole penetrating a center of the body to form an inner edge surface spaced apart from the outer edge surface; 
 a plurality of inner cutting grooves formed on the body, wherein the plurality of inner cutting grooves extend from the inner edge surface to the outer edge surface, respectively; and 
 a plurality of outer cutting grooves formed on the body and respectively disposed between the plurality of inner cutting grooves, wherein the plurality of outer cutting grooves extend from the outer edge surface to the center hole, respectively, 
   wherein the body is capable of being stretched along the plurality of inner cutting grooves and the plurality of outer cutting grooves to make a space formed by the center hole and the plurality of inner cutting grooves larger and to change an area of the body.   
     
     
         2 . The tray according to  claim 1 , wherein when the body is stretched along the outer cutting grooves, an outer diameter of the body increases, and when the body is stretched along the inner cutting grooves, an inner diameter of the body increases. 
     
     
         3 . The tray according to  claim 1 , wherein the body is stretched along two of the outer cutting grooves which are disposed in opposite directions to form two parallel short edges, and the body is not stretched along the other outer cutting grooves thus to form two parallel long edges, thus allowing the body to present as a rectangle and allowing the body to be stretched along the plurality of inner cutting grooves to form a plurality of accommodation spaces. 
     
     
         4 . The tray according to  claim 1 , wherein the plurality of inner cutting grooves and the plurality of outer cutting grooves are disposed alternately. 
     
     
         5 . The tray according to  claim 1 , wherein the body further comprises a plurality of first deformation holes, and each of the first deformation holes is respectively disposed through an end of the corresponding inner cutting groove away from the center hole. 
     
     
         6 . The tray according to  claim 1 , wherein the body further comprises a plurality of second deformation holes, and each of the second deformation holes is respectively disposed through an end of the corresponding outer cutting groove close to the center hole. 
     
     
         7 . The tray according to  claim 1 , wherein the plurality of inner cutting grooves extends toward the outer edge surface along a radial direction of the body. 
     
     
         8 . The tray according to  claim 1 , wherein the plurality of outer cutting grooves extend toward the center hole along a radial direction of the body. 
     
     
         9 . The tray according to  claim 1 , wherein the body further comprises a plurality of clamping holes disposed between the inner cutting grooves and the outer cutting grooves, respectively. 
     
     
         10 . The tray according to  claim 1 , wherein the body is made of a flexible material.
