Earlier today I asked why manufacturers package their goods in a way that makes them impossible to open?
I think shuhak's answer deserves a wider audience. ( hope you don't mind, shuhak)
They do this to ensure that the contents don't flee. There's nothing worse than getting home only to find part of your purchase has made a clean getaway. For years, manufactures received complaints about products escaping between the time they manufacturing plant and arrived at the customers home. BAtteries were famous for their ability to "vanish" in transit. It wasn't long before camps of transient batteries littered the highways. Authorities set up roadblocks in an effort to corral these rogue "power mongers". AAA's proved to be the hardest to recapture as, due to their size, they could easily slip through any roadblock or barricade. In an effort to curb this growing problem, manufactures designed containers that were 100% escape proof. While these containers proved to be excellent at incarcerating products, they had one 'slight' drawback - once locked, getting back into the container was harder than getting out. Even so, these containers have reduced the numbers of vagrant merchandise by 84%.
