Abstract: A folding tray includes a hygienic surface within the internal portion that is shielded from contamination in a folded configuration. The folding tray includes two symmetrical halves joined by a spine that allows the folding tray to close. The folding tray can include one or more inserted surfaces overlapping at least a portion of the two symmetrical halves on one side of the folding tray. The inserted surfaces can be folded into the folding tray in a folded state. The inserted surfaces can be removable or include a plurality of stacked sheets that are individually removable. The folding tray can be used to isolate materials on the tray from contaminants under the tray, or protect a material beneath the tray from contaminants on the tray.

Abstract: An apparatus for combining a stack of perforated papers contains a pin provided with a widened head, which has a round thread along its shank. The pin is passed through the holes until it abuts with its head. A nut member is screwed onto the threaded shank projecting from the other side. The pin member, together with the nut member, is manufactured by injection moulding and in one piece in a split mould.

Abstract: A Direct Access Modular Binder containing one or more posts. Each post is comprised of two or more interconnected independent locking modules. These locking modules can easily be inserted or removed to change the length of the post to efficiently accommodate varying amounts of paper. The modules additionally function to permit direct access for insertion/removal of pages or modules anywhere along the post. The modules in the post may contain a telescoping feature. The module(s) containing a telescoping feature are optimally positioned at the end(s) of the post and fixedly attached to the post holding strips. The strips, which hold the posts' ends, may be hingedly attached to the front and back covers. The telescoping feature permits the binder to be automatically compacted (when not in use), for efficient storage, and temporarily expanded (when in use), to provide space for the user to insert/remove paper or modules. The modules which make up the post are easily locked and unlocked.

Abstract: A photo album held together by attachment assemblies, each including (1) a barrel part having an internally threaded tubular portion and a plate at one end that will not pass through the openings in the pages and attachment portions of covers for the album; and (2) a screw part comprising an externally threaded portion adapted to threadably engage the tubular portion, and a head at one end that also will not pass through the openings in the pages and the attachment portions. The plates have projections received in sockets in the attachment portion of the rear cover to restrict rotation of the barrel parts; and the heads on the screw parts have ridges along their peripheries and large diameters that afford easy manual engagement with them to engage or disengage the screw parts with respect to the barrel parts.

Abstract: A tamper-proof binder has a C-shaped rectangular spine into which a plurality of clear plastic envelopes carrying photographs or the like are secured. The envelopes are permanently sealed on three side edges and open only on one side which is secured in the spine to prevent the photos from being removed. The spine has an upper T-shaped longitudinal slot on the underside of the top wall and a lower longitudinal slot on the top side of the bottom wall and a counterbored hole extends through the bottom wall into the lower slot. The envelopes have holes spaced along the open side edge which receive a headed fastener for each hole. The heads of the fasteners are slidably received in the T-shaped slot of the spine and the shafts of the end fasteners are received in the lower slot at the bottom of the spine. A center fastener is a permanent two-part fastener with a head at both ends and the shaft portions engage each other to prevent the fastener from being pulled apart after being pressed together.

Abstract: This invention relates to a multi-purpose album and in particular to one including a front cover, a back cover, a number of pages and a supporting stand. The front cover and the back cover are constituted by a flap and a slide plate, which flap has a rectangular recess at the central position for receiving a transparent plastic sheet and three raised edges. The slide plate may be inserted into the front cover and has a hinged portion which may overlap thereon. The hinged portion has two holes and two self-attaching pads. The pages are provided with two holes for receiving two sets of screws and nuts designed to bind the pages, the front cover and the back cover together.

Abstract: A hollow binder for a book having removable pages such as a ledger is used for storage of threaded posts. Each of the posts are coaxial and threaded to one another. One of the posts is adapted by itself or in conjunction with other posts to be a hand tool for threading or unthreading of posts.

Abstract: Device for interlocking a stack of writing material having perforations formed therein along a margin thereof, the perforations formed in the writing material being aligned in the stack thereof so as to form respective through-bores extending from opposite marginal surfaces of the stack that are disposed adjacent to and on both sides of a back surface of the stack, includes two binding strips of identical construction, each of the binding strips having a first portion engageable with the back of the writing-material stack for covering at least part thereof, and a second portion engageable with and covering a respective one of the opposite marginal surfaces of the stack, each of the binding strips further having stringing rods and sleeves extending from the respective second portion thereof, the rods and sleeves being disposed in mutually alternating sequence and having a mutual spacing corresponding to the spacing of the aligned holes formed in the stack of writing material, the rods being formed with outer d
