A lid and tray assembly includes at least two lift tabs and/or indentations at separated but not directly opposing locations about the lid periphery that can be actuated simultaneously or sequentially to provide two distinct locations from which initial disengagements can extend and merge to enable easy removal of the entire lid. Embodiments further include locations that can be pressed while corresponding tabs are lifted. Some embodiments include a peripheral skirt that is short enough to allow a user's fingers to pass beneath and support the tray sidewalls when lifting the tray-lid assembly from a horizontal surface, avoiding any need for the lid engagement to bear the weight of the tray and its contents. Lid-tray engagement can be by means of inserting a lid peripheral rim into a tray lip groove, or by engaging a lid rim undercut with a tray lip undercut.

The system can include: a container no, a set of sensors 120, and a controller 130. The system can optionally include a robot 140. However, the system 100 can additionally or alternatively include any other suitable set of components. The system functions to monitor and/or maintain a fullness level of a container. The system can additionally or alternatively function to enable robotic picking out of the container (e.g., in a pick-and-place setting). The system can additionally function to maintain candidate objects within reach of the robot's end effector to increase robot uptime while minimizing the extent of the robot's required motion (e.g., in the z-axis).

The present invention disclosed a simply packaged pen needle and methods of use, comprising of at least one needle body and at least one packaging body used to package said needle body, where said needle body is comprised of a needle hub, a cannula, and an inner protective cap connected consecutively, said packaging body comprises of a packaging cup and the sealing paper, said packaging cup comprises of at least one chamber coupled with said needle body, said needle hub comprises of at least one axial protrusion on its outer circumference, the inner wall of said chamber comprises of at least one groove coupled with the axial protrusion, the upper edge of said chamber is a flat surface, said sealing paper connects with the flat surface. As a result, this simply packaged pen needle and methods of use will simplify the entire manufacturing and sealing processes, significantly enhance the reliability of sterile sealing, greatly reduce product cost, especially suitable for mass production, thus is of great economic value.

Present invention relates to a locking and emptying system of a refill cartridge containing nutrients or chemicals, said system comprising at least one replaceable refill cartridge, at least one receiving socket for the refill cartridge, in every receiving socket a locking mechanism of the refill cartridge, discharge means of the refill cartridge and control means of the locking system and for each refill cartridge a emptying container. The control means of the locking system are set to release the empty refill cartridge from the receiving socket only when the emptying container has enough free volume to receive the content of the next refill cartridge,

In accordance with embodiments of the present disclosure, systems and methods for reconfiguring a vertical storage silo used to store proppant (or other dry material) so that the storage silo may be used in a desired orientation at a worksite are provided. The disclosed embodiments may include a vertical storage silo assembly used to selectively deliver material from one of two different outlet orientations. The silo assembly may offer two distinct orientations for an outlet chute relative to a transportation chassis used to transport and erect the vertical silo. The silo assembly may include a storage silo and a base for supporting the storage silo in a vertical orientation, the storage silo being removably coupled to the base. The storage silo may also be rotatable relative to the base to transition or reposition the outlet chute between a right-hand orientation and a left-hand orientation relative to the base.

The invention relates to a discharging apparatus for discharging loose and in particular pulverulent material that is hazardous to health from rigid or flexible containers (12), in particular bags and barrels (13), comprising a discharge chamber (2) which has a discharge opening (5) for discharging the material after removal from a container (12) and which additionally has an insertion opening (3) for at least partial insertion of a container (12) into the discharge chamber (2). According to the invention, the discharge chamber (2) has a ventilation opening (4) which is arranged at a side of the discharge chamber (2) opposite the insertion opening (3) and which is connected to pump means (10) in such a way that an air stream can be generated inside the discharge chamber (2), which causes a laminar air flow starting from the insertion opening (3) and leading in the direction of the ventilation opening (4).
