get value of custom field of all post of a custom type

Hi,

I have a custom post typoe called ‘product’. I found the following snippet to get alle post with this tpye. I can echo all titles, but i am tio confused to get the get_post_meta of the post. how can i refer to $post->ID inside my loop

regards

// get all products
$type = 'priduct';
$args= array(
  	'post_type' => $type,
  	'post_status' => 'publish',
  	'posts_per_page' => -1
  	);

$my_query = new WP_Query($args);

$my_query = null;
$my_query = new WP_Query($args);
if( $my_query->have_posts() ) {

    while ($my_query->have_posts()) :
      echo the_title();
      $imagepath = get_post_meta($post->ID, 'producticon', true);
    endwhile;
}

wp_reset_query();
