Vacuum Cream Container that is Operable by Rotation to Squeeze Cream Outward
First Claim
1. A container, comprising:
- a container body;
a rotation seat rotatably mounted on a bottom of the container body and provided with a shaft tube extending into the container body;
a plurality of limit bars mounted in the shaft tube of the rotation seat;
a threaded rod movably mounted in the shaft tube of the rotation seat and having a periphery provided with an outer threaded portion which has a plurality of limit slots slidably mounted on the limit bars;
an inner box mounted on a top of the container body and having an inner portion provided with a receiving chamber which has a bottom provided with an inner threaded portion screwed onto the outer threaded portion of the threaded rod;
a fixing cap mounted on an open top of the inner box to seal the receiving chamber of the inner box and having a surface provided with an outlet hole connected to the receiving chamber of the inner box;
a piston movably mounted in the receiving chamber of the inner box and connected with the threaded rod to move in concert with the threaded rod relative to the fixing cap, and an outer cover mounted on the fixing cap to cover the outlet hole of the fixing cap.

Abstract
A container includes a container body, a rotation seat having a shaft tube, a plurality of limit bars mounted in the shaft tube, a threaded rod having a plurality of limit slots slidably mounted on the limit bars, an inner box having a receiving chamber which has an inner threaded portion screwed onto the threaded rod, a fixing cap having an outlet hole, a piston movably mounted in the receiving chamber and moved by the threaded rod, and an outer cover mounted on the fixing cap. Thus, the cream is compressed by rotation of the rotation seat so that a determined amount of cream is squeezed outward from the fixing cap. In addition, the space between the fixing cap and the receiving chamber is disposed at a vacuum state by the piston to prevent the cream from contacting the ambient air.
