Description

[Detailed explanation of the idea] This case relates to a cosmetic compact.

A cosmetic compact generally has a flat body and a lid that are pivotally connected at the rear, and the closed lid is locked at the front.

The present proposal is to equip such a cosmetic compact with a push button so that the lid can be unlocked with a single touch, and also to simplify the structure and reduce failures.

The illustrated embodiment will be described below.

1 to 3 are examples, 1 is a flat body, 2 is a flat lid pivoted at the rear part 3 of the body,
4 is a push button movably mounted on the front of the body.

The body 1 has a thick front wall 11, opens forward and upward at the center of the front wall, and has a notch 12 at the front with a slightly narrow opening with both front edges 17, 17 projecting inward. The bottom of the notch is formed into an inclined cam surface 13 facing diagonally forward and upward, and an engaging protrusion 14 having bending elasticity is extended from the center of the inclined cam surface to a height that does not exceed the top surface of the notch 12. The engagement protrusions 16, 16 are horizontally provided on the upper edges of both side walls 15, 15 of the notch 12.

The lid 2 is configured such that engaging protrusions 21 having bending elasticity are vertically provided from the lower front surface thereof in correspondence with the engaging protrusions 14, and engage with each other when the lid is closed.

The push button 4 is housed in the notch 12 so as to be movable back and forth, and is formed into a U-shape in plan view so as to escape the engagement protrusion 14, and the lower surface 41 is formed into an inclined surface that follows the inclined cam surface 13, and The upper surface 42 is flush with the upper surface of the body 1 and is brought into contact with the lower surface of the closed lid 2, and guide protrusions 43, 43 are provided protruding from both side surfaces parallel to the lower surface 41 that slopes, and knurling is provided on the front surface. 44 are provided.

Thus, the push button 4 has its front part protruding slightly forward into the notch 12 so that it can be pushed in and moved freely, and the front ends of the guide protrusions 43 are connected to the front edges 1 on both sides of the notch 12.
7 and 17, and a support frame 5 having a U-shape in plan view is fitted into the upper edge of the notch 12 to prevent the push button 4 from coming off.

The support frame 5 has engagement grooves 51, 51 horizontally provided on both sides, and the engagement grooves are engaged with engagement protrusions 16, 16 provided on both side walls 15, 15 of the notch. Side 5
The lower surfaces 53, 53 of 2, 52 are connected to the guide protrusions 43,
43, and supports the upper surface of the guide protrusion so as to be movable.

With the above configuration, when the lid 2 is closed,
The engaging protrusions 14 and 21 of the body 1 and the lid 2 engage with each other to lock the closed lid 2. When the push button 4 is pushed in to open the lid 2, the push button 4 is pushed into the notch 12.
The cover 2 slides upward on the inner inclined cam surface 13, and the cover 2 is pushed up to disengage the engagement protrusions 14 and 21, and then the cover 2 can be pulled up.

Note that both the engaging protrusions 14 and 21 engage the engaging protrusions with each other, but when engaged and disengaged, they are designed to overcome elastic deformation.

FIGS. 4 to 6 show other examples, and in this case, in the previous example, the engaging protrusion 14 on the body 1 side
is formed into an L-shaped cross section, and ribs 14 are provided on the left and right sides.
a, 14a are attached to make it rigid, and the push button 4
A push-up tongue piece 45 that pushes up the lower surface of the engaging protrusion piece 21 of the lid 2 when pushed in is protrudingly provided on the inner surface of the lid. This case is also substantially the same as the previous example.

According to the present invention, by pressing the push button 4, the locking of the lid 2 can be quickly and easily released with a single touch, and by sliding the push button 4 upward on the inclined cam surface 13 on the side of the body 1, the lid can be closed. 2 is released, the push button 4 and its attachment do not require a complicated structure, do not require high dimensional accuracy, and can be constructed from synthetic resin without any problems due to its increased mechanical strength. , the number of failures can be reduced. Furthermore, push button 4
The upper surface is flush with the upper surface of body 1, and the inclined cam surface 1
Since the engaging protrusion 14 is raised from the center of the body at a height that does not exceed the upper end surface of the notch 12, there is no obstructive protrusion at the front of the body.
As in the case of a container with a projection on the front part of the body,
When taking the puff in and out of the compact, there is an advantage that there is no inconvenience such as the puff touching a protrusion and getting scratched, or white powder etc. spilling from the puff and staining the surrounding area.
