Tube structure for preserving a flower

Abstract

A tube structure for preserving a flower includes a body having an assembling portion and a storage portion. The assembling portion is defined at a top end of the body. The storage portion is defined at a bottom end of the body. A water chamber is defined in the body. The water chamber communicates with the assembling portion and the storage portion. A surrounding wall is deformable and is formed onto the assembling portion. A through hole is opened on the surrounding wall and communicates with the water chamber. A soft wall is defined around a bottom of the storage portion. A rigid wall is defined around a top of the storage portion. An angle is defined between an inner surface of the surrounding wall and a further inner surface of the rigid wall. The angle is larger than 95 degree.

What is claimed is: 
     
         1 . A tube structure for preserving a flower comprising:
 a body having an assembling portion and a storage portion, the assembling portion defined at a top end of the body, the storage portion defined at a bottom end of the body, a water chamber defined in the body, the water chamber communicating with the assembling portion and the storage portion, a surrounding wall being deformable and formed onto the assembling portion, a through hole opened on the surrounding wall and communicating with the water chamber; and   a soft wall defined around a bottom of the storage portion, a rigid wall defined around a top of the storage portion, an angle defined between an inner surface of the surrounding wall and a further inner surface of the rigid wall, the angle being larger than 95 degree;   wherein, when a flower stem is plugged into the through hole, the flower stem forces the surrounding wall to deform elastically; as a result, the surrounding wall firmly positions the flower stem; under the above arrangement, when the flower stem sucks a volume of water in the water chamber, the soft wall is deformed via a decrease of the water in the water chamber, so that the soft wall presses the water and the water is flowed upwardly.   
     
     
         2 . The tube structure for preserving a flower as claimed in  claim 1 , wherein a thickness of the rigid wall is gradually decreased toward the soft wall. 
     
     
         3 . The tube structure for preserving a flower as claimed in  claim 1 , wherein the angle is 95 degree to 135 degree. 
     
     
         4 . The tube structure for preserving a flower as claimed in  claim 1 , wherein the assembling portion is formed as awl-shaped. 
     
     
         5 . The tube structure for preserving a flower as claimed in  claim 1 , wherein a bottom of the storage portion is formed as arc-shaped. 
     
     
         6 . The tube structure for preserving a flower as claimed in  claim 1 , wherein the assembling portion and the storage portion are integrated with each other.
