  • Patent number: 9044120
    Abstract: A spice grinder is revealed. The spice grinder includes a base connected to a bottom of a container body, an inner grinding member, and an outer grinding member arranged between the container body and the base. The inner grinding member includes a plurality of grinding blades. Each grinding blade has an insertion hole on a center thereof. A rod of a fixing shaft is inserted through the insertion hole of each grinding blade. Thus a first fixing block on one end of the fixing shaft and a second fixing block on other end thereof are against a top and a bottom of the inner grinding member respectively. While in use, the container body and the base are rotated to drive the inner and the outer grinding members. Thus granular spices are ground gradually by the grinding blades. Therefore the granular spices are broken into fine grains precisely.

  • Publication number: 20130048680
    Abstract: A quantitative dispenser is disclosed. The quantitative dispenser includes a container body, a rod, a connection base, an elastic part, and a pressing element. The container body consists of a first space with an isolation ring and a second space. The rod is passed into the first space and the second space. One end of the rod in the first space is through the elastic part and is connected to the pressing element while the other end of the rod is with a pull part. A bottom of the first space is connected to the connection base and a bottom of the rod is inserted into a material discharge opening of the connection base so as to close the material discharge opening. By pressing and releasing the pressing element, a gap is formed between the rod and the material discharge opening and a constant amount of seasoning falls off.

  • Publication number: 20090223995
    Abstract: A container includes a containing body, a moving rod component held in the body, a base joined on a lower end of the body, a pressing member positioned on a top of the body and joined to the moving rod component, and a compressible elastic element to bias the pressing member upwards; the base has a tapering dispensing hole; the moving rod component has a connecting element on a lower portion, which has substantially the same diameter as the smallest portion of the dispensing hole, and usually blocks the dispensing hole, and which will move out of the dispensing hole to allow seasoning powder to fall through the dispensing hole when the pressing member is depressed; the moving rod component has a stirring spring positioned therearound, which will move together with the moving rod component to prevent seasoning powder in the containing body from sticking together to form large lumps.

  • Publication number: 20050017109
    Abstract: A grinding tool includes a toothed grinding wheel, two opposing stationary grinding members, and an actuating wheel; the grinding wheel is connected to a transmission shaft turnably connected to a housing and having an engaging end projecting from the housing; the stationary grinding members are fixedly disposed in the housing, and have grinding teeth on inward surfaces facing the grinding wheel; the actuating wheel is connected to the engaging end of the shaft at a middle connecting hole so that rotation of the actuating wheel can be passed on to the grinding wheel by means of the shaft; thus, contents of the housing can be ground with the grinding wheel and the stationary grinding members by means of holding the housing still, and turning the actuating wheel to and fro repeatedly.
