  • Patent number: 5866419
    Abstract: The invention is a roller bottle having a cross-section that is substantially a non-circular closed curve of constant width, wherein said curve is preferably a Reuleaux triangle or a Reuleaux triangle with rounded corners and the use of the roller bottle for cell culture. This provides several benefits: 1) a larger surface area per unit volume than a circular cross-section, promoting growth of anchorage dependant cells while maintaining an easily harvested and cleaned smooth wall. 2) a translational motion in addition to the usual circular motion, which is expected to enhance gas exchange, especially at the cap, which normally sits on an axis and has low angular velocity. 3) greater agitation of the growth medium inside the bottle, without the need for difficult to manufacture inserts or internal baffles.

  • Patent number: 5863126
    Abstract: A fluid mixing system is provided to permit rapid mixing of a prestored powdered substance such as powdered milk with a liquid in which, in one embodiment, baby bottles are stacked one atop the other in fluid communication, with an internally carried stemmed disk preventing powdered contents of the upper bottle from entering the liquid carried by the lower bottle until the stemmed disk is dislodged from the aperture between the bottles, the stemmed disk falling into the lower bottle such that the mixing can occur without opening or separating the two bottles. The invention thus allows the separate storage of two pre-measured fluent materials within the same container, and to facilitate the mixing and dispensing of those materials at a later time without opening the container. The benefits of this are that the user can prepare in advance mixtures of materials which, if stored in a combined state, will sour, harden, or otherwise become unusable without mixing the two ingredients until the time of use.

  • Patent number: 5794802
    Abstract: A reusable insert designed for off-the-shelf covered containers, and more specifically for baby bottles. The insert forms a storage compartment and which keeps the ingredients separated in the container. It is designed to allow the ingredients to be mixed in the same container and dispensed without removing the cover from the container. The insert generally includes a dry chamber housing 30, a chamber seal 40, and a means to release the chamber seal such as a push rod 20. When used with a baby bottle, the insert slides into the bottle portion 50. A flange at the top of the dry chamber housing 30 prevents it from moving too far into the bottle and still allows the nipple assembly 10 to be attached directly to the bottle portion 50. When the nipple assembly 10 is screwed in place, the flange is pinched between the nipple assembly 10 and bottle portion 50, forming a leak-proof seal.

  • Patent number: 5692945
    Abstract: A toy is disclosed for producing a simulated eruption. The toy comprises a container having a first chamber for holding a predetermined quantity of a first reagent and a second chamber for holding a predetermined quantity of a second reagent. The second chamber communicates with an upstanding convergent nozzle terminating at its upper end in an orifice opening to the exterior of the container. When the sidewalls defining the first chamber are squeezed, a portion of the first reagent held therein is forced through a connecting tube into the second chamber, where the first regent reacts with the second reagent to produce gaseous products. The elevated pressure thereby created within the second chamber causes the reagent mixture to be ejected from the nozzle orifice at high velocity. The toy may additionally comprise a simulated volcano landscape having a eruption tube depending from the volcano crater which receives at its lower end the tip of the nozzle.
