BEVERAGE TANK Filed Nov. 2o, 1962 2 sheetssheet 2 United States Patent Oce 3,76,830 BEVERAGE TANK Ralph L. Archbold, Euclid, Ohio, assigner to White Consolidated industries, Inc., a corporation of Delaware Filed Nov. 26, 1962, Ser. No. 238,972 8 Ciaims. (Cl. 222-158) This invention relates to containers and more particularly to a container adapted for storing and transportation of beverage syrup and maintaining the container contents under pressure.

Current designs of soft drink vending machines and soda fountain equipment include the use of a beverage syrup container of about five gallons capacity which is suited for quick connection and disconnection at the vending machine or point of use and for convenient transportation to a central distribution plant. The container is washed, sterilized and relled with beverage syrup at the distribution plant and thereafter returned to the vending machine or point of use.

It is desirable that such containers be constructed so as to be quickly and easily disassembled for cleaning and where such disassembling and reassembling operations rnay be performed so as to provide for safety in use when subjected to pressurization. Such container should be inert with respect to chemical reaction with the syrup and cleaning detergents. Stainless steel is often used to form such containers.

It is among the objects of my invention to provide a beverage syrup container or tank which will provide for convenient assembly and disassembly for cleaning and filling and wherein the container is made of resin-bonded liber glass so as to be resistant to corrosion or chemical reactions and wherein a tank is provided having desirable insulating characteristics and the tank structural parts are utilized in providing a pressure seal contributing to safety in use.

It is a further object of my invention to provide a beverage tank or container according to the preceding object wherein the container is characterized by a cylindrical side Wall construction and where the top and bottom sections of the container include peripheral cylindrical portions which are bonded within the cylindrical construction and wherein portions of the side Walls extend beyond the top section of the container to provide anchorage for an abutment extending transversely of the container.

It is a further object of my invention to provide a tank according to the preceding objects wherein said transverse abutment includes a lid holding latch and is constructed and arranged to be quickly and easily removed from the container.

It is a further object of my invention to provide a beverage tank having cylindrical side walls with integral ear portions thereof extending above a tank top section having a central opening and wherein the ears are provided With opposed apertures adapted to receive oppositely extending trunnions carried by a lid abutment unit and wherein the lid abutment unit provides a latch which may be rocked or turned to move a lid member toward the opening in the tank top section and wherein uid pressure within the container is effective to cause a deflection in the tank top section and thus assist in maintaining a pressure seal with the lid.

Other objects and advantages relating to safety and eiiiciency in operation, economy in manufacture and to ruggedness and long useful life in service will appear from the following description and the appended drawings wherein:

FIG. 4 is a sectional view of the lid holding mechanism taken along the plane indicated at 4 4 of FIG. 2;

FIG. 5 is a section along 5 5 of FIG. 2 showing manual manipulation of the lid holding mechanism; and

FIG. 6 is an enlarged sectional view of the beverage tank.

The beverage tank of the present invention includes a cylindrical side wall unit indicated in its entirety as at 6. The cylindrical side wall section 6 is made of cured resin-bonded liber glass. The cylindrical unit 6 is preferably made according to the method and apparatus disclosed in the patent to Wiltshire, No. 3,012,922 Wherein a tubular mandrel is rotated while chopped glass bers and resin are being deposited within the rotating mandrel and the cylindrical section thus centrifugally formed is then cured within the mandrel.

The beverage tank of my invention includes a bottom section 7 and a top section 8, which sections are preferably made of resin-bonded fiber glass within matched metal molds. As will be understood by those skilled in the art of ber glass forming, a metal mold having a cavity conforming to the contour of the exterior of the bottom section is fitted with a pre-form 0r loose mat of glass iibers and provided with a quantity of resin. Thereafter a matching metal male mold section having an exterior conforming to the interior shape of the end section 7 is pressed within the forming cavity and the fiber glass and resin cured under heat and pressure within such cavity. The top section S is similarly formed in matched metal molds. The cured sections 7 and 8 include peripheral cylindrical portions 7a and Sa which may be telescoped within the cylindrical side Wall section 6. In the case of the top section 8, the center portion is punched out or otherwise removed so as to provide a central opening as at 9 which is adapted to receive a lid 1i.

The lower end of the cylindrical section 6 is undercut from the open end thereof to provide a shoulder as at 12. The undercut cylindrical portion as at 13 is accurately machined so as to provide for a snug pressed lit with the peripheral cylindrical portion 7a of the bottom section 7. The proportions are such that the bottom section 7 is telescoped within the cylindrical section 6 so that the tank is supported on a surface by the lower edge of the section 6.

The end cap or bottom section 7 is provided with an annular groove 7b in the section 7a. The interior Wall of the section 6 is preferably grooved or corrugated in the area opposite the annular groove 7b. The annular opening as formed between the cylindrical section 6 in the arca indicated at 7b is then lled with resin binder material to form a secure bond between the cylindrical portion of the container and the end section 7. In this connection the joint is formed and the sections bonded to each other as disclosed in my co-pending application of Balcom and Archbold for Fiber Glass Tank, filed November 5, 8, Serial No. 772,626 now Patent No. 3,095,- 993, issued July 2, 1963.

The top section 8 of the beverage tank is secured to the cylindrical section 6 as described above and as described in said co-pending application, Serial No. 772,026.

The cylindrical section 6 of the beverage tank is formed to have an overall length to include the cars 15 and 15. The Wall sections between the ears 15 and 16S are cut away or punched out from the overall length ofthe tube and the parts thus cut out are then utilized to provide supplementary ear sections 17 and i8. The supplementary ear portions 17 and i3 are resin-bonded to the integrally Vnion portions 4l) and 4l.

enr/esso formed ears l5 and i6 as best shown in FIG. 6 wherein surplus resin, as indicated at 19 and 20, forms a smooth llet at the juncturebetween the ears and the top section 8.

An opening is provided in the oppositely disposed ear sections and a `metal grommet as at Zi and 22 is crimped into place. The metal grommets 2l and 22 along with the supplemental ear sections 17 and 18 eticiently transmit loads from the transverse abutment and handle member 25 to the main cylindrical body 6 of theA beverage tank.

. The beverage tank is provided with an carried in an aperture formed in the sloping wall of the top section 8. The litting 26 includes a body 27 whichV overhangs the litting aperture and carries a dip tube Z8. The body 27 ofthe outlet, litting is threaded at theeX- terior thereof and is clamped into place by nut 2%. The fitting 26 and the dip tube 2S are utilized to discharge outlet iitting 25 'caused by the introduction of CO2 gas through the gas inlet .ily at sixty pounds per square inch will dellect or bend the cap section S'outwardly against the lid il.

beverage syrup from the beverage tank and it will be f understood that the nipple portion 36 of the outlet fitting is adapted to be connected to the hose or tube for conducting the syrup under pressure to its place of use.

It will also be understood that the outlet tting 2:6 may be connected to a line valve to close the syrup outlet when the beverage supply is under pressure during trans- Y portation.

Y A gas inlet tting 3l is also mounted in the section 8. The gas inlet litting 31 may be constructed substantially as the litting 26 and preferably includes a check valve'(not shown) to maintain iluid pressure in the beverage container after charging the tank with gas. It will be understood that when in use in a vending machine the fitting Sil' may be connected to a supply of CO2 gasto maintain a pressure of about sixty pounds per square inch on the liquid in the tank. Y

It will be noted in connection with the litting 26 and the dip tube 28 carried thereby that the slope of the Wall in the top section 8 tilts the dip tube 2S in toward the center of the tank Yso that the lower endof the dip tube as at 28a is adjacent the lowermost portion of the beverage tank. This provides that substantially all of the syrup in the tank may be withdrawn through the dip tube'ZS.

j In forming the cylindrical section 6 which makes up the main body portion of the beverage tank resins and glassV are utilized such that the tank is substantially translucent. Thus the beverage tank may have indicia at the exterior thereof as indicated by numerals l to 4 which will give a Since the lid 1l .is backed'up or restrained against movement by the abutment unit 25, the deflection of the section S increases the sealing pressure at the gasket lila.

The member 25 includes spaced integrally formed arcuate ears 49 and Sti. VThe ears 49 and 5t? extend downwardly beneath the horizontal area occupied by the lid lll. As shown in FIG. 6, the depending ear 49 is located alongside the ange lib of the lid and the ear 5% is located alongside the opposite side of the liange lib.

Thus the user as a necessary tirst step towards disassembly of the lid and container for Washing and sterilization must release the gas pressure stored in the container and, at the same time, trap or hold the lid in a position where it cannot fly violently upward and injure the person using the container. It will be observed that it is necessary 'toslide the unit 25 laterally as illus- ,Y trated in FIG. 3 before the lid may be removed entirely from theucontainer.
