Abstract

To provide a packaging apparatus for packaging a granular object which can reduce the residual air in a package to prevent expansion thereof with an increase in temperature after sealing. The packaging apparatus comprises a charging device 30 for charging a granular object having adsorption ability into a storage bag 90 having an open end, an air removing device 50 for expelling air from the storage bag 90 into which the granular object has been charged, and a sealing device 40 for sealing the open end of the storage bag 90 from which air has been expelled, wherein the sealing device 40 is actuated with a slight delay after air has been expelled from the storage bag 90 by the air removing device 50.

1 . A packaging apparatus, comprising: a charging device for charging a granular object having adsorption ability into a storage bag having an open end; 
 an air removing device for expelling air from the storage bag into which the granular object has been charged; and    a sealing device for sealing the open end of the storage bag from which the air has been expelled;    wherein the sealing device is actuated with a slight delay after the air has been expelled from the storage bag by the air removing device.    
   
   
       2 . The packaging apparatus of  claim 1 , wherein the storage bag is formed by sealing a tube transversely.  
   
   
       3 . The packaging apparatus of  claim 1 , wherein the air removing device pinches the storage bag, into which the granular object has been charged, to expel air therefrom.  
   
   
       4 . The packaging apparatus of  claim 1 , wherein the granular object having adsorption ability is spherical adsorptive carbon.  
   
   
       5 . The packaging apparatus of  claim 1  further comprising a heating device for heating the granular object before the storage bag is sealed.  
   
   
       6 . A packaging apparatus, comprising: a sealing device for sealing a tube transversely at a first position; 
 a charging device for charging a granular object into the tube sealed at the first position; and    a pinching device for pinching the tube into which the granular object has been charged,    wherein the tube is sealed transversely at a second position opposite the first position with respect to the pinched part; and    wherein the sealing device is actuated with a slight delay after the pinching device has been actuated.    
   
   
       7 . The packaging apparatus of  claim 6 , further comprising: a first driving mechanism for driving the pinching device; 
 a second driving mechanism different from the first driving mechanism for driving the sealing device; and    a control unit for controlling the driving of the first driving mechanism and the second driving mechanism.    
   
   
       8 . The packaging apparatus of  claim 6 , wherein a face for pinching the tube is elastic and of a shape corresponding to a shape of tube containing the granular object.  
   
   
       9 . A measuring and packaging apparatus for measuring and packaging a granular object comprising: 
 a packaging apparatus of  claim 1;  and    a measuring device for measuring the granular object to be supplied to the packaging apparatus.    
   
   
       10 . A method for producing a package, comprising the steps of: supplying a granular object to the measuring and packaging apparatus according to  claim 9;   measuring the granular object with the measuring device; and    packaging the measured granular object with the packaging apparatus.    
   
   
       11 . The packaging apparatus of  claim 2 , wherein the air removing device pinches the storage bag, into which the granular object has been charged, to expel air therefrom.  
   
   
       12 . The packaging apparatus of  claim 2 , wherein the granular object having adsorption ability is spherical adsorptive carbon.  
   
   
       13 . The packaging apparatus of  claim 3 , wherein the granular object having adsorption ability is spherical adsorptive carbon.  
   
   
       14 . The packaging apparatus of  claim 2 , further comprising a heating device for heating the granular object before the storage bag is sealed.  
   
   
       15 . The packaging apparatus of  claim 4 , further comprising a heating device for heating the granular object before the storage bag is sealed.  
   
   
       16 . The packaging apparatus of  claim 7 , wherein a face for pinching the tube is elastic and of a shape corresponding to a shape of tube containing the granular object.  
   
   
       17 . A measuring and packaging apparatus for measuring and packaging a granular object comprising: 
 a packaging apparatus of  claim 4;  and    a measuring device for measuring the granular object to be supplied to the packaging apparatus.    
   
   
       18 . A measuring and packaging apparatus for measuring and packaging a granular object comprising: 
 a packaging apparatus of  claim 6;  and    a measuring device for measuring the granular object to be supplied to the packaging apparatus.    
   
   
       19 . A method for producing a package, comprising the steps of: supplying a granular object to the measuring and packaging apparatus according to  claim 17;   measuring the granular object with the measuring device; and    packaging the measured granular object with the packaging apparatus.    
   
   
       20 . A method for producing a package, comprising the steps of: supplying a granular object to the measuring and packaging apparatus according to  claim 18;   measuring the granular object with the measuring device; and    packaging the measured granular object with the packaging apparatus.
