A grass guard for forming a vegetationless border around a perimeter of an object, such as a lawn sprinkler head, is described. One particular embodiment consists of a two layer construction. The top layer is a plastic sheet simulating grass. The bottom layer is made of a heavy grit bonded into a uniform body with a polymer. The layers form a relatively thin, weather resistant, plastically compliant disk with a center hole for stretch, self-adjusting fit over a pre-installed sprinkler head. The device is also easily cut through with a knife to fit various head locations. The bottom layer has an outside vertical edge with a top rounded corner enclosing the top layer to prevent edge delamination or fraying. An adhesive is provided to bond the grass guard to the neck of the sprinkler head to eliminate gap formation around the head. A hammering board can be used to facilitate the installation. Optionally, pre-watering the vicinity of the sprinkler head until the ground is softened from moisture further simplifies the installation and enhances the quality. In general, the device can be used to guard against the growth of vegetation next to any physical objects with the proper tailoring of geometry and choice of associated manufacturing process.

Grass guard

A device for the loading of bottled fluid with no spillage consists of a valve body and a base plate coupled to the valve body in a vertically slidable manner. The valve body consists of a body, an integrated cap handle, a bottle seal and a pair of hinge brackets. The base plate consists of a body, a set of bottle stabilization posts and a pair of hinge brackets which, being coupled to the valve body through a pair of clamp levers, converts the sliding movements between the base plate and the valve body into rotations of the clamp levers to permit or prohibit the flow of fluid from the bottle regardless of its orientation while simultaneously unlocking or locking the device onto the bottle.
