Percy Williams Jiskra McBride, all of Avda. alaverry 2559, Lima, Peru Filed Aug. 16, 1963, Ser. No. 302,648 1 Claim. (Cl. 222-107) This invention relates to flexible containers for liquid or serni liquid substances wherein a valve is provided.
An object of the invention is to provide a valve in disposable, flexible containers which will serve both for filling such containers and for the use of the contents thereof without the disadvantages heretofore present in such containers.
A further object of the invention is to provide a strong container which will also be closed hermetically.
A further object of the invention is to provide a container of the type having a valve which will prevent any loss of the contents thereof from leaks.
A still further object of the invention is to provide a disposable flexible container made of laminated material which is provided with an opening produced by providing an extension upon two sheets which extensions are sealed along their side edges to their distal ends to form a tube which is then retroverted into the two sheets which have been secured together at their edges.
A still further object of the invention is to provide a container which may be easily filled by inserting the substance therein free from any atmospheric contamination and with no risk of waste.
With the above and other objects in view, a preferred form of the invention is shown in the drawings wherein:
FIGURE 1 is a plan view of a container with a portion of the front wall removed to illustrate the fiat valve and showing some liquid therein.
FIGURE 2 is a view taken on section line 22 of FIGURE 1 looking in the direction of the arrows.
FIGURE 3 is a plan view of one of the wallsofthe container illustrating particularly the extension from which the flat valve is to be formed.
FIGURE 4 is a perspective view illustrating the side walls of the extensions welded to form the flat valve and with the walls of the container separated, and
FIGURE 5 is a view of the completed container with the flat valve within the container and a filling tube inserted therein.
Referring to the drawings, FIGURE 1 shows a bag indicated generally at which is formed of two walls 11 and 12 of laminated material which are flexible and are sealed along the edges 13 by thermosetting or by means of suitable adhesives. The edge or side 14 is ice partially sealed leaving an opening 15 which is substantially equal to the width of a fiat valve 16.
The valve 16 is formed from the extensions 16' shown in FIGURE 3 and these extensions are welded along their side edges 17 as clearly shown in FIGURE 4. When the valve 16 is retroverted within the bag the open end 19 will extend to a point near the lower edge 13 of the container 10. In this way the opening 15 as shown in FIGURE 1 will communicate with the inside of the container 10 by means of the channel 18.
The product may be introduced by means of an injecting device such as 20 shown in FIGURE 5 made of a stiff material which enters through the opening 15 of the container and into the channel 18 of the valve 16 until the distal end 19 of the valve is adjacent the bottom of the container.
In order to prevent air from entering the container the container is maintained as flat as possible during the filling process but if air should enter the container such air may be extracted by suction through a nozzle entering the valve after inverting the container.
What we claim is:
A flexible container for liquid or semi-liquid substances comprising two rectangular sheets of thermoplastic material sealed together completely along three sides and along the fourth side from each edge to a region adjacent its medial portion, each sheet having an extension extending outwardly from said fourth side at said medial portion and of a width slightly less than said unsealed medial portion, said extensions being sealed together along their side edges from said fourth side to their distal ends thereby forming a tube, said tube being retroverted into the container through said unsealed portion with its distal end located adjacent the bottom of the container, so as to constitute an inlet or outlet passage for the container contents.
