Container seal

Abstract

A container seal, including a socket, a C-shaped ring, a pin, and a pointer, is provided. The socket has a jack, a slot, and a reservoir which connects to the slot. The C-shaped ring is disposed on the slot's slot wall. The pin has a tapered end and a trench disposed on a position having a first distance from an end surface of the tapered end. The tapered end passes through the C-shaped ring, making the C-shaped ring be snapped in the trench. The pointer has a neck portion and a head portion whose diameter is between the internal diameters of the slot and the reservoir. The head portion passes through the slot and enters into the reservoir, and the neck portion connects to the end surface. When the pin is pulled out, the pointer is separated from the end surface and dropped into the reservoir.

 a socket, having a jack, a slot, and a reservoir, the slot connects to the reservoir, and the internal diameter of the reservoir is greater than the internal diameter of the slot;   a C-shaped ring, disposed on a slot wall of the slot, and having a first depth from the jack;   a pin, having a tapered end and a trench, wherein the trench is disposed on a position having a first distance from an end surface of the tapered end, and the tapered end passes through the C-shaped ring, so that the C-shaped ring is snapped in the trench; and   a pointer, having a head portion and a neck portion, wherein a size of the head portion is between an internal diameter of the slot  18  and an internal diameter of the reservoir  19 , and the head portion is fixedly connected to the end surface of the tapered end;   wherein the head portion of the pointer passes through the slot, and when the pin is separated from the socket due to an external force, the pointer is separated from the end surface of the tapered end and then is dropped into the reservoir.   
     
     
         2 . The container seal according to  claim 1 , wherein the socket is transparent. 
     
     
         3 . The container seal according to  claim 1 , wherein the socket has a window, so that a checker is capable of observing the slot from outside. 
     
     
         4 . The container seal according to  claim 1 , wherein the end surface of the tapered end has a hole, and the neck portion of the pointer is tightly fit into the hole. 
     
     
         5 . The container seal according to  claim 1 , wherein the end surface of the tapered end has a locking hole. 
     
     
         6 . The container seal according to  claim 1 , wherein the neck portion of the pointer has a thread, and the pointer is locked into the locking hole through the thread. 
     
     
         7 . The container seal according to  claim 1 , wherein the pointer has a penetration hole, and the penetration hole passes from the head portion to the neck portion. 
     
     
         8 . The container seal according to  claim 7 , further comprising:
 a radio frequency (RF) chip, disposed in the pin;   a transmission conductor, disposed in the pin and connected electrically to the RF chip; and   an antenna, disposed in the socket, and passing through the penetration hole and connected electrically to the transmission conductor;   wherein a signal of the RF chip is sent to outside through the antenna.   
     
     
         9 . The container seal according to  claim 1 , wherein a needle is disposed on the end surface of the tapered end, and the needle pierces into the neck portion of the pointer so as to fixedly connect the neck portion to the end surface of the tapered end. 
     
     
         10 . A container seal, comprising:
 a socket, having a jack and a slot;   a first C-shaped ring, disposed on a slot wall of the slot, and having a first depth from the jack;   a second C-shaped ring, disposed on the slot wall of the slot, and having a second depth from the jack, wherein the second depth is greater than the first depth;   a pin, having a tapered end and a trench, wherein the trench is disposed on a position having a first distance from an end surface of the tapered end, and the tapered end passes through the first C-shaped ring, so that the first C-shaped ring is snapped in the trench; and   a pointer, having a head portion and a neck portion, wherein a size of the head portion is greater than an internal diameter of the second C-shaped ring, and the head portion is fixedly connected to the end surface of the tapered end;   wherein the head portion of the pointer passes through the second C-shaped ring, and when the pin is separated from the socket due to an external force, the pointer is separated from the end surface of the tapered end and then is dropped into the slot.   
     
     
         11 . The container seal according to  claim 10 , wherein the socket is transparent. 
     
     
         12 . The container seal according to  claim 1 , wherein the socket has a window, so that a checker is capable of observing the slot from outside. 
     
     
         13 . The container seal according to  claim 10 , wherein when the first C-shaped ring is snapped in the trench, the head portion of the pointer passes through the second C-shaped ring and has an axial gap from the second C-shaped ring. 
     
     
         14 . The container seal according to  claim 10 , wherein the end surface of the tapered end has a hole, and the neck portion of the pointer is tightly fit into the hole. 
     
     
         15 . The container seal according to  claim 10 , wherein the end surface of the tapered end has a locking hole. 
     
     
         16 . The container seal according to  claim 10 , wherein the neck portion of the pointer has a thread, and the pointer is locked into the locking hole through the thread.
