  • Patent number: 4498608
    Abstract: A container for condiments, including a body with a closure cap having a space for absorbent material, and a perforated disc holding the absorbent material in the cap. The body also has a perforated disc enabling the condiment to be shaken therethrough. When the closure cap is in closed position the entire interior space is closed to the exterior, and the moisture in the condiment is enabled to pass through the perforated discs and be absorbed by the absorbent material. In one form, the closure cap is held by screw threads and is entirely detachable, and in another case, the cap is yieldably moved to open position, although still attached, and is automatically moved back to closed position when released. In this case, interfitting elements center the cap on the body. The absorbent material includes various kinds of rice, and a selection of chemical materials.

  • Patent number: 4441458
    Abstract: A hummingbird feeder, that is usually supplied with sweet nectar and hung from above, is provided with a liquid container above it. Water, plain or containing another substance, is placed in the container, preventing ants from crawling down and reaching the feeder. The container necessarily surrounds the element suspending the feeder; the opening of the container is sufficiently large to prevent the ants from reaching the edge of the container from the suspending element, and sufficiently small to render it difficult for the birds to reach the water. In one form, the container has a funnel at the top to catch additional rain which at least partially compensates for water evaporating from the container.

  • Patent number: 4387803
    Abstract: A perforated inner container is secured in a main container for sugar, or salt, or spices, etc., referred to as condiments. An absorbent material is placed in the inner container. The absorbent material may be rice, for example, or pieces of crackers, etc. The inner container is provided with perforations small enough to confine the absorbent material, but they admit air to freely flow therethrough. The inner container is removable, for enabling placing the absorbent material therein, or changing it. In one of the forms, also, the inner container is mounted for swinging motion to physically loosen the condiment in the main container.
