7 Claims. 1
This invention relates tojwater bags, and has particular reference to syringe bags havingaflexible mouth.
' 1 broken away and in section showing the colla The conventional type flexible wide-mouth syringe bag of rubber-like material embodies a mouth normally biased toward a flattened crosssectional configuration and is difficult to fill, since it is necessary to extend the opening when filling.
This is a series disadvantage in that it is arduous to fill a syringe bag in this manner without drop-' ping it or pouring the liquid over the hand. Syringe bags of this type are purposely constructed of a thin flexible material, so that they may readily be folded into a small compact unit tion to the inside walls of the syringe bag when not in use.
Other objects will be apparent from the description and drawings which follow.
I have discovered that, if a relatively stiff collar is secured to the neck of the flat bag and is so constructed that its periphery is cylindrical, the interaction of the forces exerted by the cylindrical collar tending to distort the flattened neck portion of the bag to a cylindrical contour and the forces exerted by the flattened neck portion of the bag tending to distort the cylindrical flexible collar to a fiat contour when in equilibrium influence the periphery of the syringe bag mouth, so that the cross-sectional configuration is that of an ellipse whose minor axis approaches the length of the major axis. I have also discovered that substantially the same results may be achieved by employing a conventional relatively stiff reinforcing collar of flattened configuration, if it is-secured to the neck of the bag with its parallel sides extending transversely to the parallel walls of the bag portion. While my discovery facilitates filling the syringe bag by eliminating the necessity for stretching the mouth of the bag open during the operation, the flexibility of the bag is nevertheless retained so that it still may readily be folded into a compact flattenedunit for convenient storage.
In the drawings:
Fig. 1 is a view in elevation partly broken away and in section of a bag of pleated construction before application of the reinforcing collar;
Fig. 2 is a section on line 2-2 of Fig. 1;
Fig. 3 is a section on line 3-3 of Fig. 1;
Fig. 4is an end elevation of the flexible collar;
Fig. 5 is a fragmentary view in elevation partly in position on the bag;
Fig. 6 is an end elevation of the completed syringe bag embodying the collar as shown in Fig. 4;
Fig. '7 is an end elevation of the conventional flattened flexible collar; and
Fig. 8 is an end elevation of the completed syringe bag embodying the collar as shown in Fig. '7.
The syringe bag consists of a flexible thinwalled bag In of rubber-like material having a normally flattened cross-sectional contour. The bag In is constricted slightly at one end to form a neck H and is constricted at the other end to form an outlet M which fits into a female coupling I5.
A relatively stiff reinforcing collar l2 of rubber-like material and cylindrical contour is permanently attached to the neck II to form a mouth as shown in Fig. 6. In another embodiment of my invention, a relatively stiff reinforcing collar l3 of rubber-like material and a flattened contour maybe bonded to the bag so that the parallel sides of the collar are transverse,
" preferably at right angles, to the parallel walls of the neck II to form a mouth as shown in Fig. 8. The collar and neck portion each having a flat periphery tend to return to this contour, but being transversely opposed each exerts forces on the other member, the resulting interaction of which causes the periphery of the syringe bag mouth to assume a cross-sectional configuration resembling an oblate cylinder A tab I6 provided for gripping or hanging purposes is an integral part of the flexible collar.
The collar may be adhered to the bag with a rubber cement bond or other adhesive material suitable for bonding rubber-like substances. This result may also be accomplished by a vulcanization process whereby the collar and bag are vulcanized together to form aunit. It is convenient to use a mandrel I! in this operation to extend the flattened neck of the bag so that there will be adequate contact of the surfaces to be adhered.
Preferably both the flexible bag portion and the relatively stiff collar are vulcanized before being secured together in order that each member may achieve the desired shape independently. Each member thus acquires a permanent bias toward the configuration in which it was vulcanized and tends to retain this configuration under normal conditions i. e. when free from externally applied stresses.
Heretofore water bags of flexible flattened collar and neck construction have had an additional disadvantage in that ventilation of the inside portions was unsatisfactory. This condition results in rancid and offensive odors which are repugnant to the user. Poorly ventilated areas such as mentioned above are breeding areas for bacteria thereby rendering the syringe bag unsanitary. My invention in providing a flexible mouth syringe bag with a mouth that is normally in an open state permits increased ventilation thereby minimizing the hazard of these conditions developing. It is well known by those skilled in the art that moisture tends to deteriorate ruo- I her-like materials. The increased ventilation afforded by my invention permits more rapid and thorough drying of the inside walls of .the bag which decreases the rate of degradation thereby imparting longer life to the syringe bag.
It is obvious that minor changes in design and mater-ials'may be made without departing from the scope and spirit of the invention as defined in the-appended claims -I claim:
