Also referring to Figures 3C and 3D, the first neck portion 236 is usually conical fruit or eccentric conical fruit in configuration, the second neck portion 238 includes a radially enlarged lower section 262 with a pole or arrow projecting outwardly therefrom. The enlarged lower section 262 is placed in the bore 240 and connected to the first neck portion by a zone of frangible, weakened material 246. The application of bending stresses to the projecting post 264 as indicated by arrow 248 results in partial or complete separation of the radially enlarged portion 262 from the first neck portion 236 to allow fluid to be dispensed from the bag At through the bore 240. FIGS. 4A-4C illustrate yet another alternative fluid delivery apparatus formed according to the present invention, using an accessory 330 together with a pouch A 'as described above. The accessory 330 corresponds to the accessories 30, 130, 230 except as described and shown, and the equal components of the accessory 330 are identified using the reference numbers "300" greater than those used in Figures 1A-1C. The base similar to a flange 232 of the accessory 330 is connected to the side wall of the pouch A 'so that the perforation 340 remains in fluid communication with the interior of the pouch. The first neck portion 336 is preferably cone-shaped or frusto-conical eccentric in configuration. The second portion 338 of the neck 334 includes a radially enlarged base 362 that includes a pull tab or pull ring 364 that extends outwardly therefrom and is particularly adapted to be held by hand. The base 362 is placed in the bore 340 and connected with the first surrounding neck portion through the zone of weakened material 346. The removal of the second neck portion 338 from the first portion 336 is effected by the upward traction. and outwardly on the tongue or ring 364 away from the pouch A 'in the manner indicated by arrow 348. This action causes the radially enlarged portion 362 to be pulled away from the first neck portion 336 along the weakened area 346. to open the perforation 340 and facilitate the distribution of the fluid from the At bag. The entire accessory 330, including the traction ring 364, of preference is of a one-piece construction of a molded plastic material. Figures 5A-5C show an additional alternative fluid dispensing apparatus in accordance with the present invention including an accessory 430. Except as illustrated and illustrated in the drawings, the accessory 430 is similar in all respects to the accessory 30, and the corresponding parts in relation to the accessory 30 are identified with corresponding reference numbers ^ 400"greater than those used in Figures 1A-1C. The accessory 430 is connected to a bag A in a peripheral seam 16 as described in what is described in FIG. The accessory 430 comprises an elongated member of cylindrical, semi-cylindrical shape, or other appropriate external shape having an axial bore 440 therethrough, the bore 440, in the lower or base portion 432 of the accessory 430 remains in fluid communication with the inside of the sachet A sanitary overwrap 60 connects with or forms part of the sachet A. With specific reference to Figure 5C, a portion of the inner surface 66 of the overwrap 60 is sealingly coupled to the outer region of the neck attachment 436 by adhesive, heat fusion, or other convenient means such that the upper or opposite end of the through hole 440 is sealed in a fluid-tight manner by the overwrap 60. During the removal of the overwraps 60 to expose the neck accessory 436 to distribute fluid from the bag A, the inner surface 66 of the overwrap 60 is pulled away of the neck fitting 436 to open the through hole 440, thereby allowing the fluid to be distributed from the bag A through the perforation 440. Figure 6A illustrates a fluid dispensing apparatus with a described fitting similar to that illustrated in FIG. Figure 1A. There, the pouch A is adapted to retain the liquid, and a spout attachment 30 'connects to the pouch to distribute the liquid thereof. The accessory 30 'is similar in all respects to the accessory 30, but also includes a normally closed valve assembly 80 adapted to prevent unwanted or unintentional spillage of the liquid contents of the pouch A. For clarity and ease of understanding of the invention, the Valve assembly 80 is shown here in association with accessory 30, but those skilled in the art will recognize that the valve assembly is also suitable for use in association with the - accessories 13Q, 230, 330, 430 without deviating in any way from the scope and intent of the invention. The valve assembly 80 is made of rubber, suitable resilient polymer, or any other suitable material. The valve assembly 80 is connected to or manufactured as a one-piece construction with the rest of the accessory 30 'and placed inside the pouch interior. A bore 82 is formed through the valve assembly and placed in fluid communication with the bore 40 'in the first neck portion 36' of the fitting. The perforation 82 is placed in selective fluid communication with the interior of the bag A through a valve element 90. With reference also to Figures 6B and 6C, the valve member 90 selectively blocks the flow of fluid from the bag A towards perforation 82 and perforation 40 '. As shown therein, the valve member 90 comprises first and second side walls 92a, 92b that remain in narrow relation spaced apart from one another to define a normally closed passage or slot 94 therebetween (Figure 6B). However, the application of manual pressure directed into the valve assembly 80 in the regions of the opposite ends of the slot 94, as indicated by the arrows P, causes the side walls 92a, 92b to separate (FIG. 6C) , thereby allowing the fluid to flow between the side walls and towards the perforation 82. Correspondingly, when it is desired to distribute the fluid from the pouch To only need to apply pressure with your fingers, lips, teeth, or otherwise as indicated by the arrows P so that the fluid flows freely from the pouch A to the perforation 82, and outwardly from the perforation 40 A During the release of the manual opening pressure in the valve assembly 80, the side walls return from natural way to its normal, closely spaced relationship to close passage 94 and block the flow of additional fluid. Of course, the valve element 90 can take many other appropriate forms in order to provide a normally closed valve assembly that is capable of being selectively opened by a user during the application of pressure. Also, as with the accessory 30, the accessory 30 'can be covered by a sanitary overwrap (not shown) to prevent contamination during shipping, handling and storage. Figure 7 still illustrates another alternative fluid dispensing apparatus with spout fitting 30"including a valve assembly 80", - - placed externally. The spout attachment 30"is similar to the spout accessory 30 discussed with respect to Figure 1A, but includes a valve assembly 80" connected to or formed as a one-piece construction with the first neck portion 36"for prevent accidental or unwanted spillage of the liquid from the bag A. The valve assembly is placed outside the bag for ease of operation. Otherwise, the valve assembly 80"is similar in all respects to the valve assembly 80, and selectively also opens by applying pressure to the regions positioned at the opposite ends of the slot 94 so that it is created. a flow path of the liquid from the bag A, towards the perforation 40"to the perforation 82", and outward of the valve assembly for consumption. The invention has been described with reference to preferred embodiments. Evidently, modifications and alterations will occur to other people when reading and understanding the above specification. It is intended that the invention be construed as including all those modifications and alterations as long as they fall within the scope of the appended claims and the equivalents thereof.
