How to stop Laravel from inserting data into the database on the update page?

Question

I am creating a project in Laravel. The updatepackage.blade.phpuser has checked the box. The flag string values ​​are then stored in the database and sent to another view called printpackage.blade.php.
This is where the problem begins. When the user refreshes the page, the values ​​indicated in the entries are automatically inserted into the database. I do not know how to stop this.

updatepackage.blade.php

<td align='center'>{{$i}}</td>      
<td><input type='text' name="meter[]" readonly value="{{$item['passmts']}}" ></td>
<td><input type='text' name="points[]" readonly value="{{$item['points']}}"></td> 
<td><input type='text' name="pts[]" readonly value="{{$item['pts']}}"></td> 
<td><input type="checkbox"  name="ids[]"value="{{$i}}" /></td>

clientcontroller.php

 $insert=DB::table('packageroll')->insert(array(Input::all()));
 $tc=\Input::get('tc');
 $construction=\Input::get(construction');
 $table1= DB::table('packageroll')->where('tc','=',$tc)->where('construction','=',$construction)->get();
 return \View::make('dashboard.vendor.printpackage')->with('table1',$table1);

printpackage.blade.php

<td><input type='text' name='meter[]' value="{{$item['meter']}}" ></td>
<td><input type='text' name='points[]' value="{{$item['points']}}"></td> 
<td><input type='text' name='pts[]'  value="{{$item['pts']}}"></td>

, update, . ,

 public function store(Request $request)
    {
      $this->validate($request, ['code'=>'required|unique:consignees,''=>'',''=>'']);
    }

public function update(Consignee $consignee,Request $request)
    {
        $this->validate($request,['code'=>'required|unique:consignees,code,'.$consignee->id,''=>'',''=>'']);

    }
