Container closure with overlying needle penetrable and thermally resealable portion and underlying portion compatible with fat containing liquid product, and related method

InactiveUS20060231519A1Avoiding seal integrity problemGood product containmentCapsLiquid fillingLiquid productFormulary
A container and method are provided for storing fat containing liquid products, such as infant or baby formula, or other milk-based products. The container includes a body defining a storage chamber for receiving the aseptic fat containing liquid product, and a first aperture in fluid communication with the storage chamber. The body does not leach more than a predetermined amount of leachables into the fat containing liquid product and does not undesirably alter a taste profile of the fat containing liquid product. A container closure assembly includes a stopper receivable within the first aperture for hermetically sealing the storage chamber. The stopper includes a first material portion defining an internal surface in fluid communication with the storage chamber forming at least most of the surface area of the container closure that can contact any fat containing liquid product within the storage chamber and that does not leach more than a predetermined amount of leachables into the fat containing liquid product or undesirably alter a taste profile of the fat containing liquid product. A second material portion of the stopper either (i) overlies the first material portion and cannot contact any product within the storage chamber, or (ii) forms a substantially lesser surface area of the container closure that can contact any product within the storage chamber in comparison to the first material portion. The second material portion is needle penetrable for filling the storage chamber with product, and a resulting needle aperture formed in the second material portion is thermally resealable such as by the application of laser energy to seal the product within the storage chamber. A sealing portion of the container closure is engageable with the body prior to needle filling the storage chamber to thereby form a substantially dry hermetic seal between the container closure and body.

Vibrating element liquid discharging apparatus having gas pressure sensing

A nebulizer determines the pressure and flow direction of the receiving gas for atomized liquid. A member of the apparatus is subjected to pressure exerted by the gas. The member is coupled to a bi-directional mechanical-electrical conversion element, such as a piezoelectric element, to form a pressure transducer. The member exerts a mechanical loading on the element responsive to the gas pressure to which it is subjected. In one embodiment, the element mechanically vibrates responsive to alternating electrical energization to discharge the liquid into the gas. The electrical admittance of the element is alterable by the mechanical loading applied to the element by the member. The difference between admittances measured in the loaded condition of the element and in an unloaded condition at the selected energization frequency is an indication of the pressure of the gas. By observing whether the magnitude of the admittance in the loaded state is greater or less than that in the unloaded state, the flow direction of the gas may also be determined. Or the flow direction may be determined by observing the changes in admittance as the frequency of the electrical energization is varied. In another embodiment, the piezoelectric element is not energized. The electrical output of the element, when subjected to a mechanical loading from the gas pressure, is used to detect gas pressures and/or as an indication of the gas pressure.

Process of converting rendered triglyceride oil from marine sources into bland, stable oil

Triglyceride oil derived from marine sources, mammalian and fish, is treated with a silica at relatively low temperature under vacuum and is then further treated with a bleaching clay under vacuum and at higher temperature. The silica and the bleaching clay are then separated from the oil. The oil treated by this method is essentially free of proteinaceous materials, phosphatides and mucilage, pro-oxidant metals and very low in colored compounds, and is suitable for deodorizing. The deodorized oil is completely bland, unchanged in the concentration of the long-chain highly unsaturated fatty acids (EPA, DPA and DHA), very low in color, peroxides and secondary oxidation products, free of pesticides and has very good flavor stability. The method avoids the use of any chemicals, such as in the acid and base treatments required in conventional degumming and alkali refining of oils of marine origin. This avoids the formation of artifacts in the oil and trace contamination with chemicals. It also reduces the number of process steps required to produce deodorized food oil from marine sources, which is advantageous in respect to oil quality, process losses and processing costs. The method is especially environmentally advantageous, since it avoids the need for soapstock and waste water processing entirely. Refined oil produced by the method is useful as a nutritional supplement and in methods of therapy or medical treatment.
