Abstract
A press device for pressing powders in a container is provided. The press device has a compact structure that can be operated by one hand of a user and comprises an operation element, a pressing element, a body and at least one elastic element, wherein the at least one elastic element is provided between the operation element and the pressing element. A surface of the pressing element is urged by the force provided by the at least one elastic element to press the powders in the container.
Claims16
A press device, comprising:
- an operation element, comprising a first hollow cylinder and an outer flange surrounding the first hollow cylinder;
- a pressing element, detachably connected to a side of the operation element, the pressing element comprising a second hollow cylinder and having a pressing plate for pressing powders in a container;
- a first spring, disposed between the operation element and the pressing element, opposing ends of the first spring abutting against the operation element and the pressing element respectively;
- and
- a body having a second side configured to abut against an end surface of the container, the body having an inner flange disposed at a first side opposing to the second side;
- wherein the first hollow cylinder of the operation element, the second hollow cylinder of the pressing element, and the inner flange of the body are configured to fit in one another, the operation element is initially at a predetermined height with respect to the body, the predetermined height is a distance between an end surface of the outer flange of the operation element and a stopping surface of the first side of the body:
- wherein when the operation element is pressed to a location with the end surface of the outer flange being abutted against the stopping surface of the first side of the body, the first spring still exerts force on the pressing plate to tightly press against the powders.
