Problems solved by technology

[0008] Claws, ratchets, and elastic protrusions all belong to the ratchet pawl mechanism, and the ratchet pawl mechanism is an impact mechanism whose durability is unsatisfactory
In addition, currently known structures include a large number of parts, which also means that they are necessarily relatively complex and expensive, and have low reliability

[0105] According to the third embodiment of the present invention, the actuator 4600 includes an actuator body 4610 , a push rod 4620 and a hinge 4630 . However, it is understood that even the hinge 4630 can be omitted, as long as the push rod is arranged obliquely between the actuation body and the drive member, so that the translational movement of the actuation body is perpendicular to the longitudinal direction of the stick pack It is only necessary that the translational movement parallel to the longitudinal direction of the stick-shaped packaging of the driving member can be mutually converted. For example, a groove may be provided on the actuation body 4610 to receive the rear end of the push rod 4620 opposite the front end 4623 .

[0106] With the novel actuator 4600 according to the present invention, the user's pressing stroke can be much longer than the desired content extension. Since the required extension of the content is generally small, the lengthening of the...

Abstract

The invention relates to a strip pack, including a base portion, an actuator, a driving part, a rotating mechanism, a spring, and a cup-shaped retention piece. Inner walls of the base portion are provided with a plurality of internal projections and internal grooves. One end of the driving part is pushed along an axial direction by the actuator, and the other end is provided with a pushing portion. The rotating mechanism comprises internal thread and a projection part. The spring presses the rotating mechanism in an inclined manner. The cup-shaped retention piece comprises a screw rod which ispartially provided with external threads, and a cup-shaped portion. The external threads are joined with internal threads of the rotating mechanism, to make the cup-shaped retention piece move alongan axial direction when the rotating mechanism rotates. The pushing portion of the driving part, the projection part of the rotating mechanism, and the internal projections of the base portion are provided with inclined surfaces. When the actuator is pressed, the projection part of the rotating mechanism is pushed out of the internal groove of the base portion. When the actuator is released, the projection part of the rotating mechanism slides across the pushing portion of the driving part and the internal projections of the base portion, and then the projection part slides into an adjacent internal groove of the base portion, and thus the rotating mechanism rotates. The actuator can be pressed on a side or an end.

Description

technical field [0001] The invention relates to a stick pack with a lateral or end press actuation, in particular for containing cosmetic products. Background technique [0002] There are several types of stick packs available to hold cosmetics, such as lipstick tubes for lipsticks. [0003] A more basic type of lipstick tube has a rotatable housing. In order to apply the lipstick, the user must rotate the housing to push out the lipstick and then counter-rotate the housing to retract the lipstick. The handling of this type of lipstick tube is not convenient for the user. Controlling the amount of lipstick that is released is difficult or even impossible. In this case, the user often pushes out an excessive amount of lipstick so that it cannot be kept hygienic. [0004] Lipstick tubes using buttons have also been developed. With such a lipstick tube, the lipstick can be pushed out with just a small movement, for example a tap, and it is no longer necessary to retract th...
