Description of the Invention (/) Invention Fan Yuan This invention relates to a bag-in-box (BIC), and it is specifically related to containing and dispensing a liquid. Bag in the box. The bag-in-box container of the invention is used to store and dispense liquid to be consumed. Bag-in-box can be used to hold low viscosity liquids such as juice, or high viscosity liquids such as certain printing inks. The bag-in-box generally includes a carton, a nozzle or a perforation structure, and a liquid-proof permeation bag stored in the carton for containing a consumable liquid to be dispensed. An inner end of a nozzle having an opening for receiving liquid is coupled to the bag received in the carton. One of the nozzles projects into a carton wall to provide a liquid dispensing device. The bag itself is usually made of a highly flexible material, such as a sheet or plastic laminate, which prevents the liquid stored therein from penetrating. One of the disadvantages of the bag in a traditional box is that it may be unnecessary when the bag is flattened when dispensing liquid Blocked nozzle. In many applications, and especially when dispensing a highly viscous liquid such as ink, the bag in box is designed to not allow air to enter to replace the liquid to be dispensed. In this type of application, the flexible bag will collapse under the influence of atmospheric pressure while dispensing the liquid. Unless a preventive method is used, a part of the bag will contact and block the opening in the inner end of the nozzle when it is collapsed. If the nozzle is so blocked before the bag is completely drained, most of the bag's contents will be wasted. One solution that has been used to overcome this problem is to adhere or attach a portion of the inner bag to the carton. However, the solution will increase manufacturing costs and make handling difficult due to the need to apply adhesive to bags and / or cartons. Based on this paper size, it applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) -------: -------- install --------- order ----- ---- (Please read the precautions on the back before filling this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 475917 Α7 Β7 V. Description of the invention (>), there is an urgent need for a device that can be completely stored in the bag Liquid, minimizing liquid waste, and reducing bag manufacturing costs by eliminating the need to stick or connect bags to cartons. Summary of the Invention The present invention can overcome the above-mentioned disadvantages related to the design of the known bag-in-box. The invention provides an inner bag provided in a carton for containing a liquid. A nozzle is set on the carton and extends into the paper bag. The nozzle provides a path to direct liquid flow. A cap is attached to the nozzle to protect the nozzle during storage before use. A compressible spring system mounted on the nozzle extends into the inner bag and prevents the inner bag from squashing onto the nozzle when liquid is consumed. The invention will be described below with respect to a printing press application of the ink of this liquid system, but this is for illustration purposes only. However, the present invention is not limited to the use of ink, and a variety of different liquids can be used regardless of their viscosity. The ink is dispensed from the inner bag by the suction of an auxiliary printing mechanism, which is well known in the art and exceeds the scope of the present invention. As liquid is dispensed from the inner bag through the nozzle, the inner bag will collapse inwardly onto the nozzle. The compressible coil spring prevents the inner bag from collapsing against the nozzle opening to ensure that the entire ink can be dispensed. As more ink is dispensed, the inner bag will be further squashed and push the compressible coil spring inward towards the nozzle. When the spring is compressed inward, the inner bag will be squashed further until the amount of ink remaining in the inner bag is minimal. One of the advantages of the present invention is its advantages in manufacturing cost compared to the traditional box-in-bag that adheres or connects the inner bag to the carton β.

The preferred embodiment illustrates that the bag-in-box system according to the present invention is designed to maximize the utility of the liquid and minimize the waste of the liquid while reducing manufacturing costs. The bag-in-box of the present invention will now be described with reference to Figs. Fig. 1 shows a specific embodiment of a bag-in-box 100 filled with liquid to be dispensed. An inner bag 104 is housed in a carton 106. The inner bag 104 may be made of any suitable material. Those skilled in the art are aware of these suitable materials. Preferably, the inner bag 104 is made of a material that does not chemically change with the contents of the bag, the contents are impermeable, and have sufficient strength to withstand any external forces that may be subjected to manipulation and use without damage or other loss of original appearance. Made of possible materials. Various laminated or sheet structures are also suitable as materials for inner bags. The carton 106 is preferably a box that is substantially closed and can be of any conventional shape, such as rectangular, and can use low-cost materials such as cardboard. A liquid 112 to be dispensed from a bag in the box is contained in the inner bag 104.

Invention Description (+) 112 can be a highly viscous liquid such as an ink. The invention is not limited to ink, but can use a variety of different liquids regardless of its viscosity. The present invention is particularly applicable to bag-in-box containers that do not allow air to enter the bag when dispensing liquid and therefore will flatten when the contents of the bag are consumed. Figure 1 shows the inner bag 104 in a full state. The inner bag 104 is made of a flexible material to flatten it after dispensing liquid. According to the present invention, the inner bag 104 does not need to be adhered or attached to any surface of the carton 106. A nozzle 108 for dispensing liquid from the inner bag It is mounted on the carton 108 and extends into the inner bag 104. The nozzle 108 is also depicted in FIG. The nozzle 108 is preferably mounted at the lower end of one surface of a carton 106. The nozzle 108 is generally cylindrical and has an outer end 120 extending outwardly from the carton 106 and an inner end 130 extending into the interior of the carton 106 and into the interior of the inner bag 104. A hollow channel 140 provides a communication path that allows the liquid in the inner bag 104 to be distributed from an opening 150 formed in the outer end 120 of the nozzle 108. The inner bag 104 is hermetically connected to the inner end 130 of the nozzle 108. The nozzle 108 is made of any suitable material that is compatible with the liquid contents of the bag in the box. Plastic is a better material due to its low price and also molding. A compressible coil spring 102 is mounted on the inner end 130 of the nozzle 108 and extends into the interior of an inner bag 104. The coil spring 102 may also be made of any suitable material that is compatible with the liquid contents stored in the bag in the box. Preferably, the elastic coefficient of the coil spring 102 allows the coil spring to be flattened when the liquid is dispensed and the inner bag 104 is flattened. The outer end 120 of the nozzle 108 has a threaded portion 113 on the periphery. This paper size is in accordance with China National Standard (CNS) A4 (210 X 297 mm) -------: -------- ----- Order --------- " ^ 1 ^ " (Please read the notes on the back before filling out this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 475917 A7 B7_ V. DESCRIPTION OF THE INVENTION (^) The flange 122 is formed on the periphery of the nozzle 108 and is used to allow the inner bag 104 to be hermetically mounted thereon. The nozzle 108 has an annular groove 124 formed between two flanges 155, 156 for fixing the nozzle to the carton 106. The external end of the nozzle 108 can be formed to fit a connector of an external device such as a printing press (not shown) such as a liquid in a bag in a consumption box to be dispensed. The external device will apply a suction force to draw the liquid out of the bag in the box. A cap 110 can be screwed onto the threaded portion 113 of the outer end 120 of the nozzle 108 to protect the nozzle from injury and to prevent a seal 170 from piercing or damaging the bag in the box before it is used. Fig. 2 is a side view of the bag in the box of the present invention after all the liquid 112 has been dispensed and the inner bag 104 has been flattened. When the liquid 112 is discharged from the inner bag 104, the atmospheric pressure will flatten the inner bag toward the nozzle. If no compressible spring 102 is present, before all the liquid in the inner bag 104 is exhausted, a part of the flattened inner bag 104 contacts and blocks the opening 180, causing unnecessary waste of liquid. The present invention uses a compressible coil spring 102 to overcome the above disadvantages. When the liquid 112 has been dispensed and the inner bag 104 is flattened, the compressible coil spring 102 will prevent the inner surface of the bag from blocking the opening 180 in the nozzle 108. After a certain state, dispensing more liquid 112 will further squash the inner bag 104 and push the compressible coil spring 102 inward toward the nozzle 108. Preferably, the modulus of elasticity of the compressible coil spring 102 allows it to compress when the inner bag 104 is crushed. Fig. 2 shows a fully compressed state of the compressible coil spring 102 after the liquid 112 has been completely dispensed. The present invention can completely use the liquid 11 2 and minimize the liquid waste, but the paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) ----- I! ---- · Packing --- ---- 丨 Order --------- ^ 0- (Please read the notes on the back before filling out this page) Printed by the Consumer Consumption Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 475917 A7 ___B7___ V.
