Abstract: A lighting unit (2) for marine or other underwater use has an array of LEDs (60, 62) mounted in groups (46) on a printed circuit board (6). A plastic injection moulded collimator is associated with a group of LEDs and a group of such collimators are provided in a single contiguous moulding which can also provide a cover (20) and means for mounting the lighting unit to a vessel and facilitates sealing of the unit.

Abstract: A lighting unit (2) comprises a base member (8) supporting a plurality of LEDs (4) on a PCB (6), a specular reflector (10) surrounding the LEDs in order to direct low angle rays out of the unit. A moulded glass Fresnel lens plate (20) is mounted across the reflector above the PCB, and a clamping member (30) seals the base member and the lens plate in order to create a water tight unit.

Abstract: This invention is directed to an improved reclosable bag having first and second walls and an open top. The open top has first and second flexible fastener strips attached thereto. One of the strips has a profile portion forming a groove; the other strip has a profile portion forming a rib with a portion of the rib received and retained in the groove when the bag top is closed. Each of the fastener strips has a base connected to the respective walls. The bag has a slider mounted on the fastener strips which is movable longitudinally along the fastener strip to progressively separate the rib from the groove to open the bag, and is movable in the opposite direction to progressively return rib to a retained condition in the groove and create a leak-proof seal. A cradle is formed near one end of the fastener strip which is sized, constructed and arranged to receive and retain the base of the slider when the fastener strip is sealed to prevent leakage from that end of the fastener strip.

Abstract: A fastener strip, such as would be used in a reclosable container, comprises a sealing member having a plurality of sealing portions configured to engage complementary sealing portions of a complementary fastener strip. At least one sealing portion comprises one or more finger members extending therefrom. The at least one finger member, by engaging a complementary sealing portion of a complementary fastener strip, provides an additional degree of sealing, particularly when the fastener strips are in a partially engaged condition. A slider comprises top and side walls and inwardly facing flanges, preferably at lower ends of the side walls. The inwardly facing flanges define a gap having dimensions such that the sealing members of the opposing fastener strips, and particularly the sealing portion having the at least one finger member and its complementary sealing portion, are urged together to provide an additional degree of sealing, yet not completely interlocking, engagement.

Abstract: A child resistant closure having an outer cap and an inner cap combined together. The caps are provided with complementary engaging ratcheting teeth making it possible to turn the caps as a unit in a closing direction but permits relative rotation of the caps upon rotation of the outer cap in an opening direction unless the outer cap is simultaneously deflected axially relative to the inner cap. Complementary load bearing surfaces are provided on the caps to prevent axial deflection when the caps are in a predetermined position and the caps resist rotation from this predetermined position.

Abstract: A closure comprising a top wall with an annular side wall depending there from. An induction foil is proximate an inner surface of the top wall and may have a ring or circular configuration. An RFID device is affixed or is integral with the closure a minimum distance from and/or orientation with the induction foil as to prevent damage to the RFID device during an induction sealing process and to reduce adverse operational effects of the RFID from the foil. The RFID may be active or passive and may be proximate or integral with the top wall or integral with the side wall of the closure. The RFID may be contained within a film wherein a portion of the film is inductively sealed to the closure.

Abstract: A non-removable closure having a radio frequency identification, RFID, circuit integral therein. The RFID may be active or passive and may be integral with the top wall or side wall of the closure. The non-removable closure has a closure retainer which non-removeably engages a container neck at to which it is engaged. The closure retainer may be in the form of “J” hooks depending from the bottom portion of a side wall, an adhesive between the container neck and closure, or other closure retainer known to persons having ordinary skill in the art.

Abstract: A method for manufacturing a reclosable pouch having front and back walls and an opening along its upper edge. A double web of plastic material is advanced which comprises a front wall and a back wall. First and second fastener profiles are advanced simultaneously therewith. The first fastener profile is sealed on its ends to the exterior of the front wall of the pouch. The fastener profile extends longitudinally near the pouch opening. The second fastener profile is sealed on its ends to the exterior of the back wall of the pouch. The fastener profiles are adapted for interlocking with the front and back walls of the pouch being interposed therebetween.

Abstract: A reclosable flexible container is provided as a pouch having a front wall with an inside and an outside surface, a rear wall with an inside and an outside surface and a pouch opening. A pair of exterior closure elements are provided for mechanical interlocking with a pair of interior closure elements. A wall of the pouch is interposed between each interior and exterior closure element. The interior closure elements further have a mechanical mechanism for selective interlocking with each other so as to seal the pouch or reopen it as desired. As a result a reclosable pouch is provided without the use of heat seals or adhesives.

A first fastener profile is sealed on its ends to the exterior of the front wall of the pouch. The fastener profile extends longitudinally near the pouch opening. A second fastener profile is sealed on its ends to the exterior of the back wall of the pouch. The first and second fastener profiles each have a rib member extending longitudinally thereon and a groove for reception of the oppositely disposed rib. The fastener profiles are adapted for interlocking with the front and back walls of the pouch being interposed therebetween. A method and apparatus for manufacturing the aforesaid pouches are also described herein.

Abstract: A resealable container having flexible side walls defining an access opening, and a sealing cuff disposed internally of said access opening. The sealing cuff is formed from a film sheet having a first marginal edge affixed to the container about the periphery of the access opening and having a free second marginal edge extending into the container. The sealing cuff defines mutually oposed surfaces having high cling characteristics so as to form a seal therebetween when brought into surface engagement. An external cuff having high slip properties may be formed peripherally of the access opening to facilitate opening of the internal sealing cuff.

Abstract: A reclosable flexible container is provided as a pouch having front and back walls and a pouch opening at the upper edge thereof. The pouch has a cuff about the periphery of the pouch opening. A first fastener profile is affixed to either the cuff or the front wall of the pouch. A second fastener profile is affixed to the rear wall or to a cuff affixed to the rear wall. The fastener profiles may be selectively interlocked so as to seal the pouch with at least one wall of the pouch being interposed therebetween and engaged therein.
