  • Patent number: 6183827
    Abstract: A lid for foodstuff containers includes a shell shaped so that it can be fitted over an opening in a container, and a PVC-free seal, bearing an inscription, attached to the bottom of the shell and able to seal the lid to the container; the seal is applied to the bottom of the lid by applying adhesive paint between the bottom and the seal; this paint which can be used to control the adherence of the seal to the bottom, consists of a mixture of synthetic resins and hydrocarbons with added metallic pigment; a film bearing the inscription is applied over the paint, said inscription made using an ink which has a given chemical-physical affinity with the material used for the seal; it is, therefore, easy to detach the seal from the bottom of the lid upon which the inscription is clearly reproduced.

  • Patent number: 5896686
    Abstract: By employing an award determining prize member incorporating a lens constructed to cooperate with printed indicia which produces a minimum of two separate and distinct visual images, depending upon the angle at which images are viewed, a unique and highly valued prize member is created, as well as prize award members which are incapable of having prize related information observed by the consumer prior to purchasing the item. In the present invention, the visual image representing the prize award information is quickly and easily mounted to the inside surface of a cap and is constructed with at least one image thereof being visible only when viewed at an angle which is substantially perpendicular to the surface of the indicia. In this way, advance determination of winning prize members by consumers prior to opening and removing the cap from the container is eliminated.

  • Patent number: 5720392
    Abstract: The present invention is a device for indicating when a person either took a pill or other medication, or when he is scheduled to take the next dose of the medication. The invention is conveniently attached to a pill bottle having a cap. An image of a clock face is printed on or adhered to the top of the bottle cap and/or the bottom and may include either a MEDICATION TAKEN AT image or a MEDICATION DUE AT image. A transparent, rotatable cap, having an arrow indicator inscribed thereon, is placed over the bottle cap. A second transparent, rotatable cap, having an arrow indicator inscribed thereon may be placed over a clock face image and a medication image on the bottom for use as a second timer reminder. When a medication is taken, the rotatable cover covering the MEDICATION TAKEN AT end is turned to the time taken. The opposite end timer is then turned to the MEDICATION DUE AT end to indicate when the next dose is due.

  • Patent number: 5592766
    Abstract: An improved container closure and printed matter insert. The closure includes a central recess for receiving the insert with an inwardly projecting flange for retaining the insert therein. The closure includes an outer skirt, a top wall, and an angled side wall defining the outer boundary of the central recess. The inwardly projecting flange does not extend above the top horizontal surface of the top wall, thus helping to prevent binding in assembly line. The insert is defined by a central circular disk portion and a plurality of outwardly extending tabs. The tabs are formed with lines of weakness along the peripheral outline of the central disk portion, to enable them to flex upward above the plane of the disk. The lines of weakness may be score lines or perforations. When inserted into the recess of the closure, the tabs of the insert conform to the angled side wall and extend approximately from the central floor to the inwardly extending retaining flange.
