Embodiment Construction

[0049] Such as Figures 1 to 4 As shown, a prior art dispenser head 100 is provided with a piston rod 11 or post extending through a collar 20 into a cylindrical pump body 30 to push against one end of a spring 31 . The spring 31 is used to provide a restoring force to the piston rod 11 . The cylindrical pump body 30 is provided therein with a groove 32 and a check ball 33 held in the groove 32 . When an external force is applied to the actuator 10, the contents of the cylinder 30 are dispensed. In consideration of the fact that the actuator 10 is prone to be accidentally or unintentionally applied external force, the cylindrical pump body 30 is provided with a locking ring 21 at the top end. However, if the dispenser head is inadvertently reversed, the locking ring 21 and / or the pump body 30 become disengaged because it is not sufficiently secured with the rest of the dispenser head 100 . Leakage can also occur at high temperatures or when it falls over, such as figure 1 ...

Abstract

The invention relates to a pump unscrewing structure and provides a distributor head (100) extending in the X-axis. The pump unscrewing structure comprises a hollow pump body (30), a clamping ring (20) connected to the top end of the hollow pump body (30), a piston rod (11) extending to penetrate through the clamping ring (20) and enter the hollow inside of the pump body (30), an actuator (10) fastened to the top end of the piston rod (11), and a locking ring (21) arranged between the clamping ring (20) and the actuator (10) and connected to the actuator (10) by point-pressing a locking system.

Description

technical field [0001] The present invention relates to a cosmetic dispenser head, and more particularly to a safety lock structure of the dispenser head, a packaging and / or application device with the dispenser head and a container for storing the product. [0002] The cosmetic is preferably a liquid, cream, lotion, gel or foam. The cosmetic product is, for example, a make-up product, a cleaning or care product for the hair or the skin. [0003] More generally, "cosmetics" are products as defined for cosmetics in EU Regulation 1223 / 2009 of the European Parliament and of the Council of 30 November 2009. Background technique [0004] For applying cosmetics, it is known to use a container and a spray head assembly connected to the container. The user obtains liquid from the container by depressing the actuator of the spray head assembly. [0005] Dispenser heads are known in the prior art with safety features for preventing accidental or unintentional dispensing of the cont...
