Abstract: A package for dispensing and separating single sheets from a continuous web of pre-moistened sheets which are joined at perforations includes a continuous web of premoistened sheets, and a bag which may but need not be found within a container, surrounding the web. The bag is open at a top end portion thereof, and an end sheet of the web extends through the open top end portion. A flexible tie device is positioned to surround the end sheet of the web and the top end portion of the bag and gathers and substantially seals the bag around the end sheet of the web. The flexible tie device causes sufficient friction between the top end portion of the bag and the end sheet to enable the end sheet to tear from the next sheet of the web at the perforations therebetween when the end sheet is withdrawn. The flexible tie device is adjustable to enable selective alteration to adjustment of the size of the opening through the opened top end portion of the bag and the end sheet.

Abstract: A hygienic product for cleaning parts of the body comprising a moistened napkin and a quantity of powder capable of absorbing moisture. The napkin is contained in a first air-tight envelope-like compartment of a packet, and the powder is contained in a second air-tight compartment of the packet. The two compartments may have a common wall between them, in which case each compartment has an outer wall opposite the common wall, whereby all three walls are tearable along a "tear-open" line simultaneously to open both compartments at the same time. The powder may be loose or, alternatively, may be carried by a soft pad or applicator contained within the second compartment.

Abstract: The invention contemplates improved techniques for making lens implants for use in ophthalmological surgery, the lens being a replacement for a cataract-clouded natural lens. The lens of the invention is particularly adapted for posterior-chamber implantation, with position stability derived from the inner wall of the natural-lens sac (from which cataracted material has been removed). A manipulative tool in combination with the lens assembly (1) provides safe stabilizing support during storage and transit prior to the surgeon's access for operative use, and (2) is configurated to facilitate operative placement of compliant retaining feet within the sac, permitting posterior-chamber positioning of the lens prior to tool removal.

Abstract: An open-top container receives a dental tool support in the form of an open-bottom cylinder provided with threads around its upper and lower ends engageable with internal threads at the upper end of the container so that the support may be held by the container in either an upper or lower position.

Abstract: A moist tissue dispenser in which a web of absorbent sheet material divided by transverse lines of perforations into interconnecting tissue is saturated with a liquid cleansing agent and coiled into a roll having a hollow core, the roll being housed within an open-mouthed container. The leading end tissue of the roll extends upwardly from the core and passes through a frusto-conical central orifice in a removable cover received over the mouth of the container. The orifice functions as a converging passage whose constriction forces the end tissue to rope and to effectively plug the orifice, thereby maintaining the container in a sealed state to prevent evaporation of the cleansing agent. The orifice constriction and its configuration are such as to impose a drag on the roped end tissue as it is pulled from the dispenser by a user and funnelled through the orifice.

Abstract: A disposable diagnostic swab assembly which takes the form of an elongated tubular member having an internal chamber which is permanently closed at the inner end and is openable at the outer end by the removal of a cap. A culture medium containing breakable pouch is located within the internal chamber at the inner end. An elongated swab is attached to the cap with the tip of the swab being located directly adjacent the pouch. The pouch is to be breakable by applying localized pressure upon the tubular member in the area of the pouch which causes the culture medium to saturate the tip of the swab. A glass slide section may also be attached to the tubular member with access to the glass slide being permitted to facilitate usage thereof.

Abstract: A self contained disposable cauterizing system for use in cauterizing benign mucous membrane ulcerations, lacerations or fissures. The system includes a swab having an elongated handle with an absorbent swabbing tip on one end of said handle and with a coating of silver nitrate applied to the opposite end of said handle, an elongated flexible plastic tube and matching cap and a frangible ampoule filled with topical anesthetic, which ampoule is fittable in the plastic tube. In use, the portion of the tube where the ampoule is located is squeezed by the physician user, fracturing the ampoule and allowing the topical anesthetic to be absorbed by the absorbent swab tip. The swab is then withdrawn from the tube after the tube cap is removed, with the topical anesthetic end of the swab being applied to the ulceration, laceration or fissure to render the area insensitive to pain and silver nitrate is thereafter applied from the opposite end of the swab to the affected area for cauterization.

Abstract: A recloseable dispenser packet wherein articles, such as moisture impregnated towelettes, are readily accessible to the user.

This structure includes a collar portion which is hermetically sealed to the flexible packet material and a detachable hinge member with snap-on type cover cap attached thereto. The flexible packet may also be made of three-part laminated material. Another embodiment of the limp-pack device is formed of overlapped and sealed material with gussets provided at each end of the sealed pocket.

Abstract: A package for medical needle assemblies and the like including a shield, a cap, and a closure. The shield encloses the needle and a portion of the hub. The cap is mounted on the shield so that it is shiftable between two positions. In the first position it protects the exposed portion of the hub extending from the shield and in the second position it is slidable along the shield to expose the portion of the hub projecting from the shield to facilitate grasping and removal of the needle assembly from the package. The closure covers the opening in the cap and is removable when the package is opened. The closure in working cooperation with a sealing engagement between the cap and the shield seals the needle assembly in the package.

Abstract: There is disclosed a novel electrode assembly or package for two or more electrode devices, and also a novel method of fabricating not only the overall assembly, but also the devices in conjunction therewith. The electrode assembly as contemplated by the disclosure includes a carrier member in generally strip form having one or more openings therein, the number of said openings depending upon and being equal to one-half of the number of electrode devices to be employed in said assembly. A medical electrode device is secured in overlying relation to each opening, on opposite sides of the carrier member, with the gel pads of each said electrode device being disposed within the periphery of the opening and in face-to-face contact with the pad of the opposed electrode device. The electrode devices may be pre-gelled, if desired. It is contemplated that the assembly may then be packaged in a suitable container, such as a plastic or foil envelope.

Abstract: A container is disclosed including a relatively rigid tray sealed by a removable cover comprising a pair of plastic, bacteria-impermeable panels defining a generally linear passage for the introduction of sterilizing vapor for sterilizing the contents of the container after sealing thereof. The passage is sealed by a membrane, such as a paper strip, bonded to the panels about the passage. The paper strip is impermeable to bacteria but highly permeable to the sterilizing vapor.The passage may be defined by overlapping margins of the plastic panels. Covers employing panels with overlapping margins may include discrete spaced-apart heat seals joining the margins along the length of their overlap to increase the strength of the cover and insure its removal in one piece. By making the panels of transparent plastic sheet material and using a paper strip having a small surface area relative to the overall surface area of the cover, the contents may be readily identified visually through the panels.
