Abstract: A vent valve for a closed tank, the vent valve being provided in an upper surface of the closed tank storing liquid, may include an upper housing provided with an upper air hole disposed outside the closed tank; a lower housing provided with a lower air hole disposed inside the closed tank; and a valve core provided in a housing space area surrounded by the upper housing and the lower housing and providing a ventilation path through which only gas passes between the upper air hole and the lower air hole.

Abstract: A modular tray system for counting and/or storing ammunition components is described. Embodiments of the modular tray system can include, but are not limited to, a base tray, one or more spacers, one or more adapter trays, and a cover. The one or more spacers and the one or more adapter trays can each be configured to operate in combination with the base tray. The cover can be configured to be placed over outer edges of the base tray.

Abstract: Cap for drink bottle or similar recipient that comprises a base element comprising a drinking nozzle and a substantially tubular portion adapted to be secured to a neck of the bottle or recipient, a covering element comprising a flip top adapted to hermetically seal the drinking nozzle of the base element, and anti-tamper means of the top adapted to provide a visual indication of whether the top has already been removed for a first time from the drinking nozzle; the covering element comprises a tubular portion adapted to be secured to the outside of the substantially tubular portion of the base element, and the anti-tamper means of the top comprise an interlocking element extended from a lower edge of the top; wherein, the interlocking element is adapted to latch through the inside a front window of the tubular portion.

Abstract: The closure cap for a container comprises an internal fastening skirt (16), an external skirt (18) radially surrounding said internal skirt at least partially, and a front wall (14) from which said skirts extend. The internal skirt (16) has a variable thickness in the direction of its axial length, said thickness being at a minimum at least for a proximal portion (22) of said skirt which extends from the front wall (14). The internal skirt (16) comprises the proximal portion (22) with a thickness E that is substantially constant, a distal portion (24) with a thickness E2 that is substantially constantand greater than the thickness E1, and a connecting portion (26) that connects the proximal portion and thedistal portionand has a variable thickness E3 along its length. The axial length of the proximal portion (22) of the internal skirt varies around the circumference of said skirt.

Abstract: Container having a body portion with sidewall defining outer perimeter and hollow interior. The body portion includes a plurality of continuous ribs extending about the outer perimeter of the sidewall, each rib having alternating horizontal segments and branched segments. Each branched segment includes a top branch and bottom branch joined at either end to define a bounded area therebetween. The plurality of continuous ribs includes at least a first continuous rib and second continuous rib spaced vertically from the first continuous rib. A midpoint of each branched segment of the first continuous rib is aligned along a vertical axis with a midpoint of a corresponding horizontal segment of the second continuous rib, and a midpoint of each horizontal segment of the first continuous rib is aligned along a vertical axis with a midpoint of a corresponding branched segment of the second continuous rib.

Abstract: A Bottle cover/liner for separating clean water or other liquid and blocking it off from the dirt, germs, and bacteria on outside surfaces while the clean water or other liquid is being removed from the bottle into a reservoir or dispenser, as well as, blocking contaminants from air borne movement into the ambient.
