摘要:
A container for siftable products such as powders, solid particulates, spices, condiments and the like, comprises a bottle having a threaded neck, a screw cap for the bottle, and a sifter member disposed in the cap. The cap and sifter member are yieldably held together to constitute an assemblage which is applied to the bottle after the latter has been filled. The applying of the cap to the bottle forces the sifter to be transferred to and firmly secured on the bottle neck by cooperable configurations thereon, which provide a more aggressive grip or securement than the hold of the cap on the sifter. In consequence, whenever thereafter the cap is removed from the bottle, the sifter will remain operatively secured to the bottle to carry out its function.
摘要:
A container constituted of injection-molded plastic components, the components having the property of enabling discrete particles thereof to be securely joined to each other under the action of heat and pressure. The injection-molded components form a pair of continuous mating edges adapted to constitute a common continuous joint in the container. The edges initially have configurations enabling them to be mutually abutted, and the edges after being so abutted having been subjected to heat and pressure of a magnitude sufficient to cause them to meet and merge into each other to form the continuous joint.
