Abstract: An apparatus for collecting particles or vapor from air or surfaces comprising: a housing comprising an inlet open to the air to be sampled and an outlet; and a fan having one or more open areas within the housing capable of being driven at a speed effective to cause collection on the surface of the fan of particles or vapor in the air. A method of collecting a particulate sample from air comprising the step of driving a fan having one or more open areas within a housing comprising an inlet open to the air to be sampled and an outlet, at a speed effective to cause collection on the surface of the fan of particles in the air.

Abstract: A container assembly includes a container and a closure that has plural vents formed proximate its top member, preferably at a transition between the top member and the skirt. The closure includes a feature that spaces apart an edge of a liner, outside of which the vents are formed, and provides tamper protection. The closure and the container neck form a top and corner seal therebetween while the closure is in a fully closed position, and provide a gap when the closure is in a vented position. P gases within the container escape through the gap and the vents when the closure is unthreaded from the fully closed to the vented position. The vents may be configured such that the vent outlet is oriented substantially vertically to vertically direct the outbound gases to prevent closure blow-off and to avoid impinging against a user's hand.

Abstract: A compression failure resistant tamper evident bottle cap includes a skirt with a lower edge, and a tamper-evident band formed integrally with the skirt and having structure for engaging beneath a retaining flange on the bottle so as to prevent subsequent withdrawal of the band. Frangible bridges connect the band to the lower edge of the skirt. To prevent destruction of the bridges as the cap is forced onto the bottle during installation, the skirt has one or more tabs or the like, extending downward over a portion of the band, for preventing undue diametral expansion of the tamper evident band as it passes over the retaining flange.

Abstract: The TE-band (3) of a closure cap for closure of a container is provided with retaining elements (5) which protrude radially inwards and upwards to the base of the closure cap from the inner surface of the TE-bank (3). Each retaining element (5) comprises a retaining surface (6) terminating in a retaining edge (7). The retaining edges engage beneath an engagement surface (10) on the mouth of a container when the closure cap is in position on said container. The retaining edge (7) are formed as a concave segment and all retaining edges (7) together define substantially a circle. The circle is coaxial with the engagement surface of a container mouth and has a diameter which is smaller than the outer diameter of the engagement surface of the container mouth.

Abstract: A plastic closure includes an annular ring durably attached to the container, and a sealing assembly installed in the ring to seal the mouth. The sealing assembly includes a plug having a sealing lip on its lower face and a release lever connected to the plug by a flexible hinge. A tab on the release lever can be lifted to pry the sealing assembly out of the opening. The ring has a free edge directed downwardly and inwardly so as to permit the plug to pass easily through the opening during assembly, or resealing, but to resist removal of the plug sufficiently to prevent it from being forced off the container by pressure within the container.

Abstract: A can closure includes a plastic insert permanently installed in a hole in the can top, and a plug which seats in a pouring aperture extending through the insert. Locking dogs on both the insert and the plug provide a bayonet-type connection so that the container can be resealed after its contents have been partially used. Protrusions on the locking dogs prevent the plug from being fully removed until pressure within the container has been relieved.

Abstract: A tamper-indicating closure serves as a closure for a container (2) which, at its container neck (3), possesses at least one locking surface (5) with which the retaining elements (6) of the tamper indicating band (7) are able to engage. The tamper-indicating band (7) possesses an upper portion (10) which extends downwards from the cap skirt (12) and which is connected with this by a frangible line (11). A plurality of retaining elements (6) are provided on the upper portion (10) of the tamper-indicating band (7). The retaining elements (6) are in each case connected with the adjacent retaining element by a flexible web (13). Each of the retaining elements (6) possesses at least one wedge shape (8) on its surface oriented towards the container neck (3).

Abstract: A plastic tamper-indicating closure (1) possesses a closure cap (2) on which, by means of weakened web portions (5), a tamper-indicating band (6) is fixed. The tamper-indicating band (6) is provided with a number of blocking elements (8). The blocking elements (8) are connected with the tamper-indicating band via integral hinges (7). During screwing onto the container neck, the blocking elements (8) can be pivoted upwards and radially outwards into a first closed position (I). As opposed to this, during opening of the tamper-indicating closure the blocking elements are pivoted downwards and radially inwards into a second opening position (II). With that, the effective internal diameter will be reduced, by which means the blocking element will be held in engagement with the corresponding locking surface on a container neck.

Abstract: A cap and valve actuator for spray dispensers used with aerosol containers, which includes a cap and a valve actuator member positioned therewithin and with the valve actuator member cooperating with the depressible discharge part of the spray dispenser, with the cap body having a circumference substantially that of the aerosol container so as not to extend substantially outwardly thereof, to permit the containers with caps thereon to be positioned contiguous to each other, and with the cap having an outlet opening at the front side thereof; the cap having a finger receiving socket extending inside the cap and accessible through a side rear opening in the cap body; the valve actuator having a socket for engagement with the valve stem of the aerosol container and a forwardly extending portion extending substantially to the front side outlet opening of the cap, with the forwardly extending portion of the actuator having a duct communicating with the socket engaging the valve stem of the aerosol container.
