Have a look at the perldoc of IO::Compress::Zip. It mentions an option FilterName, which could be used.

Quoting:

...

Filtername => sub { ... }

... For example, the code below shows how FilterName can be used to remove the path component from a series of filenames before they are stored in $zipfile.

    sub compressTxtFiles
    {
        my $zipfile = shift ;
        my $dir     = shift ;

        zip [ <$dir/*.txt> ] => $zipfile,
            FilterName => sub { s[^$dir/][] } ;  
    }

Update

Did a test; it works ;-)

#! /usr/bin/env perl
use strict;
use warnings;

use File::Basename      qw( basename );
use IO::Compress::Zip   qw( zip $ZipError );

my @files = glob(  'data/*/*.dat' );

my $zipfile = './zipped.zip';

print "zipping $_\n"  for @files;


zip [ @files ] => $zipfile,
  FilterName => sub { $_ = basename($_); };

__END__
# source files
data/foo/FOO.dat
data/bar/BAR.dat

# files in zip (according to 'unzip -l')
FOO.dat
BAR.dat
