Description

The invention relates to packaging and for blister packaging of padlocks and a method for protecting locks from atmospheric agents and dust during operation.

Known one-piece blister packs for single use [1] and detachable blister packs [2].

The indicated packages are intended to protect goods only during their storage and transportation.

Also known padlocks equipped with visors to prevent dust and moisture from entering the lock body [3], and locks equipped with turnkey closing wells with covers of various designs.

The disadvantage of these locks is the complexity of the design and, therefore, the great complexity of manufacturing.

The technical result achieved by this invention is to protect padlocks during operation from rain, snow and dust without the use of special visors, cuffs, oil seals and covers in the design.

The specified technical result is achieved by the fact that the lock when hanging on the ears of the door is inserted into the blister element, which serves as its packaging and protects the lock from atmospheric precipitation and dust.

The blister element contains two interconnected blister parts with the possibility of folding. One part covers the product with a recess that follows the contours of the lock, and has a recess for accommodating the ears, and the other part contains a window for inserting the blister element into the ears.

Figure 1 shows the blister element in an open form, containing blister parts 1 and 2, which can be folded in place 3. In part 1 there is a recess 4 for accommodating the door ears and a recess 5, repeating the contours of the lock and covering the product. In part 2 there is a window 6 for insertion on the door ears. The blister parts are provided with a protrusion 7 and a corresponding cavity 8 for fixing them.

Figure 2 shows the blister element in a folded, closed form. Window 6 is represented by a protruding outward frame 9 adjacent to the plane of the door during operation of the lock. When storing the product, the window can be closed with a blister cover or sealed with foil.
