Iron cans: child safety packaging


The common structure of child safety cover is screw cover, screw cover and meter cover. It is a functional lid designed mainly for the contents of the iron box packaging container that is not suitable for children to touch or eat.

Child safety cover design features:

The structure design of child safety cover is based on the intelligence and strength characteristics of children under five years old, so that children can hardly master the opening method in a short time, or know how to open the iron cover, but it is difficult to open the lid because of the insufficient strength of the hand. The purpose of designing the child safety cover is to prevent ordinary children under the age of 5 from opening the package within a certain period of time from the packaging structure, so as to prevent children from taking certain drugs by mistake,
Household chemicals and chemical products and damage to health and even life-threatening accidents.

The remarkable feature of the structure of the child safety cap is that it uses a simple structure and low cost to achieve the purpose of preventing children from opening the cap, and is convenient for adults to use.

child safety cover design principle:

The structure is relatively complex, and it is difficult for children to open in a short time (usually 5min).

This structure requires a certain strength, that is, children under 5 years old do not have this strength, such as children's grip strength is only about 140N. The persistence of force is also poor, so it is difficult to open the cap structure that requires sufficient grip and a certain endurance to open.

3. Mark the bottle cap with words to indicate the opening method, while children under 5 years old have almost no word recognition ability, and adults can open it smoothly through the prompt.

To prevent children from accidentally or accidentally swallowing harmful substances. In order to protect children, a variety of child-protective can lids have been developed for use in child-resistant opening packages (CRC). The two most commonly used are as follows:

 

Screw cap:


The screw cap structure is connected through the inner and outer double-layer structure and the card slot. If the cap is opened, the outer layer cap needs to be pressed down and the inner layer cap is driven to rotate to open the bottle. Since this opening method involves applying force in two directions, the safety effect of iron box packaging is improved and children under 5 years old are prevented from opening. The tinplate safety cover also adopts this structural principle. The iron box safety cover structure not only ensures the beautiful appearance of the outer cover, but also enhances the structural strength of the outer cover, fully guarantees the service life of the tank cover, and ensures that it will not slip, idling and unscrew. The phenomenon occurs.

 

Meters cover:

 

 

The structural principle of the meter cover is to fasten the cover and the body of the can through the concave-convex clamping groove. This requires the cover and the body to be twisted at the same time, and the strength should be coordinated, while children under 5 years old can hardly twist the cover and the body at the same time.

 

Safety cover

The structure of this kind of safety cover is to achieve the safety effect by installing the lock catch. The lock catch can be pressed with both hands at the same time to drive the inner button to open. Since such an opening method involves simultaneous exertion of both hands, it is difficult for children to synchronize their hands. Significantly reduce the risk of exposure to children.


The innovation of child-proof safety packaging not only plays a role in protecting children's safety, but also brings greater benefits to consumers, but also provides innovation opportunities for canning manufacturers.
