Abstract

A latching system for use with a dispenser having a cover hingedly connected to a back plate for movement between open and closed positions. The cover includes a latch plate or tongue which is disposed adjacent its top or now hinged end. The latch plate has one or more through apertures therein for engagement with an engagement bar carried by the back plate with the engagement bar having one or more upwardly projecting ribs for engagement with the apertures of the latch plate when the cover is closed. The back plate also carries a movable latch bar selectively movable into contact with the latch plate to disengage the latch plate from the projecting ribs. The back plate also includes one or more projecting support ribs underlying the cover it its closed position.

Claims

1. A latching system for a dispenser having an elongate back plate, an elongate cover, one end of which is pivotably connected to one end of the back plate for movement between open and closed relationship with said back plate comprising:

a) an elongate latch bar slidably mounted on the back plate for selective movement longitudinally thereof;

b) a latch plate carried on the end of the cover opposite its point of connection to the back plate;

c) latch plate engaging means carried on the end of said back plate opposite its point of connection to the cover and releasably engagable with said latch plate to retain the cover in its closed position, wherein said latch plate engaging means is separate and distinct from said elongate latch bar, and selective movement of said elongate latch bar causes said latch bar to contact said latch plate and release said latch plate from said latch plate engaging means; and

d) at least one support projection disposed on and projecting from the back plate, wherein, when the cover is in its closed position, said at least one support projection extends through an aperture in said latch plate and engages an internal surface of the cover, and the pivoting of said cover from its closed position to its open position, without employing said latch bar to release said latch plate from said latch plate engaging means, requires the breaking of said at least one support projection.

2. The latching system of claim 1 wherein said latch plate has at least one through aperture therein;

said latch plate engaging means include at least one projecting rib extending toward the cover when the cover is in its closed position; and

said rib including at least one engagement projection for releasably engaging said at least one through aperture in said latch plate.

3. The latching system of claim 2 wherein said engagement projections are tapered from a minimum height to a maximum height toward the back plate.
