    • A downhole cleaning apparatus (10) comprising a tubular body (12). The tubular body (12) comprises comprising a plurality of openings (20) therethrough. Each opening (20) defines at least part of a helix extending longitudinally and circumferentially about the tubular body (12). The downhole cleaning apparatus (10) also includes a plurality of cleaning elements (22). Each cleaning element (22) is configured to extend through an opening (20) and to extend outwards from an outer surface of the tubular body (12). The cleaning elements (22) are distributed about the tubular body (12) and each cleaning element (22) defines at least part of a helix extending longitudinally and circumferentially about the tubular body. The openings (20) and the cleaning elements (22) are grouped to define a plurality of substantially continuous helical paths (18). Each helical path (18) extends substantially end to end of the tubular body and the helical paths (18) are distributed relative to each other to define a cleaning surface of at least 360 degrees.

    • A combination handle clamp, beverage bottle and can opener having a generally curved shaped body and integral attachment point to allow connection to other personal item such as a key ring. A secondary and tertiary integral curved section form a pair of loading points for fixing open a handle-trigger assembly and incorporate a gripping edge to facilitate opening a crimped or vacuum sealed bottle top. The tertiary curved section additionally functions as a second clamp position for the larger handles and also doubles as a pry mechanism to assist opening a pop-top can. The said gripping edge of the invention which contacts with said bottle top to be constructed of a durable material that won't abrade from its intended use.
    • 组合手柄夹具,饮料瓶和开罐器具有大致弯曲的形状的主体和整体附接点,以允许连接到其他个人物品,例如钥匙圈。 二级和三级整体弯曲部分形成一对加载点,用于固定打开手柄触发器组件并且包括夹紧边缘以便于打开压接或真空密封的瓶顶部。 第三弯曲部分另外用作较大手柄的第二夹持位置,并且还兼作撬动机构以帮助打开弹顶罐。 本发明的所述夹持边缘与所述瓶顶接触,以由不耐磨材料构成,其不会磨损其预期用途。
