The invention includes a package blank of unitary construction which may be assembled to form said package containing said product in a specially configured die, as well as a particular die useful therewith. The package of the present invention is inexpensively manufactured and is of durable construction.

Abstract: The open top of a container is surrounded by a rim having a curved upwardly presented surface and a slight ridge projecting upwardly from the curved surface. A seal membrane containing a metal foil extends over the open top of the container and seats against the ridge on the container rim. A flexible lid fits over the membrane and interlocks with the rim so that the membrane is interposed between the ridge and the lid. The lid has a downwardly opening annular groove which receives the container rim and this causes the seal to wrap generally around the curved upper surface of the rim. Once the lid and membrane are in place, the membrane is induction heated above the melting point of the container material, while a downwardly directed force is applied to the lid. The ridge, which is in contact with the seal membrane, melts down and thereafter is allowed to cool while the force is maintained on it, so that when the material solidifies, it is bonded to the membrane.

Abstract: Prefabricated fingers suitable for mounting on a printed circuit board for use in conjunction with card edge connectors are provided on a lengthwise strip which may be cut to the desired size to correspond with the number of fingers which are to be mounted on the board. The strip, which may be formed in a roll, includes a pair of parallel carriers. The fingers extend between and are integrally formed with the carriers and are spaced along the lengths thereof and in substantially coplanar relationship therewith. After severing one of the carriers, the resulting free ends of the fingers may be aligned in overlapping relation with the circuit conductor ends to which the fingers are to be joined.

The tray has a plurality of cassette positioning rib sets for positioning and retaining cassettes inserted into the tray in parallel transverse arrangement with a cassette recorder coupling edge parallel to the tray bottom and the cassette sides portions defining the cassette recorder coupling means of each inserted cassette touching or nearly touching adjacent cassettes. The case has a latch for openably latching the tray and tray cover in closed position and a carrying handle.

Abstract: A simplified chemical dispenser apparatus capable of dispensing a predetermined amount of a treatment chemical into a fluid includes a porous matrix exhibiting capillary action when the fluid contacts a surface of the matrix, a fluid treatment chemical composition located on a surface of the matrix, and housing means for covering said chemical composition and at least said chemical bearing matrix surface to shield against dripping or splashing from the top or sides. The housing may be applied as an envelope in which case the chemical supported upon the matrix is sealed therein.

Abstract: Fastener attachment stock to be separated or divided, e.g., by cutting, severing, rupturing or shearing to provide a plurality of fastener attachment devices each preferably having substantially an H shape. The stock in its most preferred form includes two undivided elongated and continuous plastic side members having a plurality of plastic cross links coupled to and between each of said side members, each of said links being preferably spaced equidistantly apart from each other.The stock of this invention provides for a completely waste-less or scrap-less fastener attachment dispensing system in the hands of the ultimate user while also permitting the automatic repetitive dispensing of large numbers of fastener attachment devices under positive feed control and at a rapid rate without the necessity of frequent system stock reloadings (as necessitated using the stock of the prior art).

Abstract: A device for holding film strips and the like in proper position on spiral reels or the like such that the film will be held onto the reel in proper spaced relation to permit the flow of the developer about the film for development thereof. The device includes a longitudinally extending body having a transverse dimension which will permit the device to extend across the width of the film and thus the corresponding spiral reel to contact the edges of the film and hold the same against the spirally formed elements of the reel. The device is designed to lock into the reel between the spiral elements thereof and may be used for full or partial strips of film.

Abstract: A shadow display carton and blank for making same with top and bottom portions of a front panel in position to frame the article to be displayed, and die cut folded sections at the top and bottom of the carton to support and restrain the article away from the end panels of the carton.

Abstract: A package for articles such as cans, bottles, and the like, comprising a corrugated paperboard tray, a film sheet covering said articles, and an adhesive connecting opposite ends of said film sheet to opposed walls of said tray. The sheet may be heat shrunk to hold said articles to the tray and have opposed fully or partially closed ends which overlap the sides of the articles. The sheet may be stretch film that does not require heat shrinking, or it may be plain paper. The package may include an inverted top tray, with or without holes that receive the tops of the articles, to keep the articles in vertical alignment. The package may be double tier.

Abstract: A carrier having substantially flat projections which extend from the carrier to snugly and slidably bear heat recovered sleeves thereby conforming to the flattened configuration of the projections. After positioning generally tubular heat recoverable sleeves over the projections and partial recovery of the same, printed information may be easily imparted to the sleeves on a modified typewriter or the like. The sleeves may then be removed from the projections and employed as identifying markers for electrical wire or other like articles to be marked. The sleeves may be further heat recovered in position on the marked article to snugly fit thereon.
