Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an extremely easy-to-use device for opening and closing the lid of a compact container, which allows the lid to be opened with one touch with one hand.

Problems that conventional technology and devices aim to solve: With conventional compact containers, when the hook engagement is released, the elasticity of the spring causes the lid to open with great force all at once, making it somewhat difficult to operate with one hand, and the majority of compact containers require both hands to open and close.

The purpose of the present invention is to provide a compact container that is very convenient to use and allows the lid to be opened slowly and smoothly by holding the container with one hand and opening the lid with one touch without having to open the lid all at once. It is something.

Means for solving the problem In this proposal, by applying a link mechanism, when the lid is closed, torque acts to keep the lid in close contact with each other.
When the fulcrum is pushed up above top dead center using the operation button, the direction of the torque changes, and the lid opens automatically with the force of the spring, and the opening speed is moderately reduced to allow it to open slowly. The lid body 3 is equipped with a shaft pin 4 on the rear edge of the container body 1 so as to be able to be opened and closed freely, and a cylindrical frame 5 formed on one side of the container body 1 is fitted with a spring 7. A sliding member 6 which is pressed against the sliding member 6 is inserted into the sliding member 6, and a connecting rod 8 whose mounting portion is attached so as to be bendable is protruded from the tip of the sliding member 6. The provided projecting piece 9 and the tip of the connecting rod 8 are pivotally connected with a pivot 10, and when the lid body 3 is closed, the pivot 10 is located at a slightly lower position than the pivot pin 4. The pivot shaft 10 is pushed up to a position above the shaft pin 4 by means of an operating button 12 rotatably mounted on one side of the container body 1, and a hole in the sliding member 6 is used. The cylindrical frame 5 is attached to the brake groove 13.
The gist is that the sliding member 6 is braked by engaging a brake piece 15 projecting downwardly inward and applying viscous oil to the brake piece 15 and the brake groove 13, respectively. .

Embodiments The details of the present invention will be explained below with reference to the embodiments shown in the drawings. 1 is a container body having an inner tray 2 into which cosmetics are loaded; 3 is a container main body 1 which can be opened and closed by a shaft pin 4 on the rear end edge thereof; 5 is the container body 1
The sliding member 6, which is a cylindrical frame formed on one side, is always pressed in the direction of the opening by the elasticity of a spring 7. The attachment part 8' is cut into a thin wall and protrudes from a connecting rod 8 which is attached so as to be bendable. Reference numeral 9 is a protruding piece provided inside the shaft portion of the lid body 3, and a pivot 10 provided on the protruding piece 9 is engaged and connected to an engagement hole 11 bored at the tip of the connecting rod 8, When the lid 3 is opened or closed, the pivot 10 is set at a lower position than the shaft pin 4 of the lid 3. Reference numeral 12 denotes an operation button rotatably mounted on one side of the container body 1, and its operation piece 12' is set below the connecting part between the protruding piece 9 and the connecting rod 8. 12, the operation piece 12' pushes up the connecting portion of the protruding piece 9 and the connecting rod 8, and moves the pivot 10 onto the axis pin 4. Reference numeral 13 denotes a plurality of brake grooves bored in the sliding member 6, which are engaged with a plurality of brake pieces 15 that project downward from a part of the middle frame 14, respectively.
5 and the brake groove 13 to reduce the opening speed of the lid body 3.

Function and effect of the invention Therefore, in this invention, when the container is held with one hand and the operation button 12 on the side is pressed, the operation piece 12' pushes up the connecting part between the protrusion piece 9 and the connecting rod 8, and the pivot 10 moves beyond the top dead center. When the shaft pin 4 is in the upper position, the spring 7
The sliding member 6 moves in the opening direction of the cylindrical frame 5 due to the elastic pressure, and the lid 3 automatically opens. Further, a brake piece 15 is engaged with the brake groove 13 of the sliding member 6, and the brake piece 15 and the brake groove 13 are coated with viscous oil, and the sliding member 6 slides under the elastic pressure of the spring 7. A braking action is applied to the movement of
The lid body 3 can be opened slowly and smoothly without opening all at once. Incidentally, as the position of the pivot 10 moves upward, the attachment portion of the connecting rod 8 bends upward, ensuring smooth movement of the sliding member 6.

Next, when the lid 3 is closed in the open state, the sliding member 6 retreats toward the deep part of the cylindrical frame 5 against the spring 7, and when the lid 3 is completely closed, the sliding member 6 moves back toward the deep part of the cylindrical frame 5. The connecting portion of the connecting rod 8, that is, the pivot shaft 10, is set at a slightly lower position than the shaft pin 4, and this action changes the direction of the torque, and the elasticity of the spring 7 acts in the direction of sealing the lid 3, ensuring a secure seal. This provides a closed lid condition.

As mentioned above, in this case, when the lid 3 is closed, the pivot 10 is set at a slightly lower position than the pivot pin 4,
A torque is applied in the direction in which the lid body 3 is brought into close contact with the lid body 3, preventing the lid body 3 from being opened inadvertently and ensuring a secure and stable closed state. When the position is pushed up to a position slightly higher than the shaft pin 4, the lid body 3 will automatically open slowly and smoothly without opening all at once.
Therefore, it is possible to open the lid with a single touch by holding the container in one hand, and it is possible to obtain a compact container that is very easy to use and gives off a luxurious feel when the lid is opened slowly.
