A method of injection molding a test tube-shaped preform for biaxial stretch blow molding includes supplying a major material resin from outer and inner flow paths to a combined flow path for a predetermined time and rate. For a period of time within a range of the predetermined time period during which the major material resin is supplied, the intermediate layer resin is simultaneously supplied from the middle flow path to the combined flow path at a second predetermined supplying rate. A columnar laminated molten resin is injected into a cavity of a metal mold connected to a tip of the nozzle through a gate to fill the cavity, the columnar laminated molten resin being composed of the major material resin and the intermediate layer resin formed in the major material resin in a laminated manner that are combined into a columnar shape at the combined flow path.

The disclosure generally describes computer-implemented methods, software, and systems for gauging tanks. A computer-implemented method includes generating, using an interrogator, a radio frequency signal directed towards a radio frequency identification (RFID) device that is freely floating on the liquid stored within the tank, receiving a return signal from the RFID device, the return signal being associated to a location of the RFID device, processing the return signal to determine a height of the liquid stored within the tank based on a triangulation algorithm, and determining a result data based on the height of the liquid stored within the tank and one or more tank characteristics.

The present application provides a child-resistant liquid dispensing closure apparatus, which includes a plunger and pipet, and preferably a dosage measuring system that is integrated that appears as the plunger is withdrawn from the pipet. The closure may be used for a bottle containing a liquid for oral administration of solutions, syrups, suspensions, elixirs, tinctures, concentrates, and the like.

A polymer vial with a tubular body having a geometric shape including (i) a neck having an opening orifice, and (ii) a closed base formed by flattening and sealing a bottom edge of the tubular body. The vial will also include a snap off cap integrally formed on the neck and a liquid content contained in the tubular body. A plurality of dosage lines are printed on the tubular body, the dosage lines having a non-uniform spacing corresponding to the variable volume per unit length of the vial geometric shape. Each line corresponds to a dosage volume of the liquid content when the opening orifice is oriented in the vertically upward position.

A closure for a bottle includes an upper portion, a lower portion attached to the upper portion and including a flange extending inwardly from an interior wall of the lower portion, and the flange resides entirely within the lower portion. The closure further includes one or more grip elements located on an outer surface of the lower portion, and an annular sleeve disposed in the lower portion and including a set of interior threads.

An illustrated view of an improved food container for saving space when the food container is less than full is presented. The improved food container is useful for reducing an amount of storage space necessary to store the improved food container. Furthermore, the food product inside of the improved food container will have preservability because it will contain less air. The improved food container further is useful for providing an indication of the amount of food product remaining in the improved food container.

A beverage container lid can include an audio speaker; a wireless transceiver to transmit and receive wireless signals; and a hardware processor to process wireless signals received by the wireless transceiver and to output audible signals through the audio speaker. The beverage container lid can also include a water-tight housing, the wireless transceiver and hardware processor contained within the water-tight housing; a drinking aperture; and a fluid channel, the fluid channel to allow fluid to pass through the drinking aperture, and the water-tight housing to prevent fluid passing through the fluid channel from contacting the wireless transceiver and hardware processor.

The tumbler bottle includes a cup having a side wall interior surface and bottom wall a convex interior surface. The cup side wall and bottom wall interior surfaces are joined by a smooth, arcuate interior transition surface to define a first mixing chamber. The tumbler bottle further includes a lid, removably connected with the cup. The lid includes a side wall interior surface and a top wall concave interior surface. The lid side wall and top wall interior surfaces are joined by a smooth, arcuate interior transition surface to define a second mixing chamber. The lid further includes a dispensing outlet and a closure. When coupled together the first mixing chamber and the second mixing chamber are in fluid communication and are configured to uniformly mix a liquid with one or more additives.

A shaker device includes a storage body, a lid, and a measurement system. The storage body also includes an opening and a hollow area. The storage body is configured to retain and selectively dispense an amount of a material disposed in the shaker device. The opening is disposed on a terminal end of the storage body. The lid is selectively disposed over the opening. The measurement system is configured to identify an amount of the material within the shaker device.
