One corner is opened, and the open corner of the bag is provided with an ice pack bag having a hook portion formed to catch the absorbent body.

Here, it is preferable that the engaging portion is formed by partially bonding the front side and the rear side.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

However, in describing the present invention, a detailed description of known functions or configurations will be omitted in order not to disturb the gist of the present invention.

1 is a perspective view before the ice pack of the first embodiment of the present invention is sealed.

As shown, the ice pack 100 of the first embodiment of the present invention, the front face 111 and the back face 112 are bonded to each other, one edge 113d is open and the envelope 110, the envelope 110 It is composed of an absorber 120 is inserted into the having a material that absorbs water. The open edge 113d of the envelope is formed with a catching part 114 to catch the absorber 120. In addition, the liquid material 130 is filled in the bag 110.

 The liquid material 130 is a material having a large heat capacity to increase the cooling effect and the cooling time such as water, a high absorbent polymer or a mixture thereof, and an additive for realizing a function such as freezing point drop may be added. When water is used as the liquid material 130, an additive for lowering a freezing point such as salt may be added.

The absorber 120 is a component for absorbing the liquid material 130 in a liquid state, and a material for easily absorbing the liquid material 130 is used.

As the material of the absorber 130, a nonwoven fabric, a porous member, a sponge, or the like may be used, and the absorber 130 may be manufactured in a block shape having a predetermined thickness to maintain a constant shape. Sponge refers to sponges made of natural rubber or synthetic resin.

The absorber 130 absorbs the liquid material 130 having fluidity, thereby preventing fluidity of the liquid material 130 and preventing the liquid material 130 from being pulled to one side according to the loaded state of the ice pack 10. In addition, the absorber 120 may be processed into a rectangular parallelepiped or other various shapes, thereby enabling the manufacture of the ice pack 100 having various shapes. Meanwhile, the absorber 120 may further include a shape reinforcing material (not shown) such as a wire for reinforcing shape.

The envelope 110 is sealed to accommodate the absorber 120 in which the liquid material 130 is absorbed to prevent the liquid material 130 from leaking to the outside.

The bag 110 may be made of a synthetic resin film such as polyethylene, polypropylene, vinyl, or a nonwoven fabric. The manufacturing method of the bag 110 is generally used a method of fusion by applying heat to the three corners (113a, 113b, 113c) of the two front (111) and the back (112).

The locking portion 114 is formed by partially bonding the front surface 111 and the rear surface 112. In other words, when the three corners 113a and 113b are fused together, they are formed by fusion together. The distance between the locking portions 114 is formed to be smaller than the width of the absorber 120.

In the manufacture of the ice pack, in general, after the absorber 120 is inserted into the inside of the bag, the liquid material is filled, and then the open edge 113d is fused to complete the manufacture of the ice pack. In general, the specific gravity of the absorber 120 is low, so that the absorber 120 floats toward the open edge 113d in the step of filling the liquid material. Therefore, it interferes with the process of bonding the open edge 113d. The locking portion 114 prevents the absorber 120 from rising above a certain height, so that subsequent processes are easier.

As described above, the ice pack according to the first embodiment of the present invention has an advantage that the overall thickness of the ice pack is uniform because the liquid material is absorbed into the absorber and frozen and thawed by the absorber 120 therein.

Moreover, by providing the locking part 114, it can prevent that an ice pack rises in a manufacturing process.

However, when frequent freezing, thawing, and moving, the catching part 1114 may be damaged to leak liquid material. In order to solve this problem, a liquid filling apparatus for filling a liquid material into the bag shown in FIG. 2 without the catching part 114 is required.

And, due to the presence of the catching part 114, it is too cumbersome to put the absorbent into the bag, which is not suitable for mass production.

In addition, when there is a large amount of air inside the ice pack has become a factor to irregularize the shape during freezing, there is a need for a liquid filling device that can effectively discharge it.

Figure 3 is a simplified plan view of the liquid filling apparatus of an embodiment of the present invention, Figure 4 is a simplified front view of FIG.

 As shown in these figures, the liquid filling apparatus includes a clamper 1200 installed in the frame to hold the filling device frame 1100, the inlet 213 of the bag 200, and an envelope clamped to the clamper 1200 ( Press movably installed in the filling device frame 1100 to press the absorber 120 through the inlet 213 of the bag 200, the liquid injection device 1400 for injecting the liquid through the inlet of the 213 And a bonding device 1600 installed in the charging device frame 110 to bond the portion 1500 and the inlet 213 of the bag 200.

Therefore, after pressing the absorber 120 downward through the pressing unit 1500, since the inlet of the bag 200 is bonded, it is possible to prevent the sponge 120 from being disturbed in the bonding step.

In addition, the inlet opening device 1300 installed in the filling device frame to open the inlet of the envelope 200 clamped to the clamper 1200, and the supply unit 1800 to sequentially supply the envelope 200 to the clamper 1200 ), A discharge unit 1900 for discharging the completed ice pack, and a cooling unit 1700 for cooling the heated heat during bonding.

The clamper receives an envelope from the supply unit 1800, and then, the inlet opening device 1300, the liquid injection unit 1400, the pressing unit 1500, the bonding unit 1600, the cooling unit 1700, and the discharge unit 1900. It is installed in the charging device frame 1100 to move sequentially.

The supply unit 1800 includes a conveyor belt 1810 through which the bag into which the absorber 120 is inserted is transported, a transport roller 1820 installed on the conveyor belt 1810 to transport the bag 200 one by one, and a transport roller. The adsorber 1830 which is adsorbed on the upper surface of the envelope conveyed by the 1820 and moves upward, and the inlet of the envelope 200 lifted by the adsorber 1830 is clamped to the second position at the first position (I). And a moving device 1840 for moving to the clamper 1200 in (II). Since the mobile device 1840 may be configured with a plurality of link structures, and may be appropriately designed and modified according to the first position and the second position, detailed description thereof will be omitted. In addition, the configuration of the supply unit 1800 may be implemented in various ways.

As shown in FIG. 5, the clamper 1300 has a clamper main shaft 1310, a clamper jaw 1320 having one end hinged to the clamper main shaft 1310, and one end of the clamper jaw 1320. Jaw drive shaft 1330 and one end is hinged to the clamper main shaft 1310 and the other end is hinged to the jaw drive shaft 1330, one end is fixed to the crank 1340 and the other end is clamper main A restoring spring 1350 fixed to the shaft 1310 and a clamper driver (not shown) coupled to the crank 1340 to drive the crank 1340.

5, when the crank 1340 is driven by the clamper driver (not shown) in the clockwise direction, the jaw drive shaft 1330 moves accordingly, and the clamper 1320 rotates from the clamper main shaft 1310. Will be opened. When both edges of the inlet of the bag are inserted between the clamper jaw 1320 and the clamper main shaft 1310, the clamper driver (not shown) drives the crank 1340 counterclockwise, so that the clamper 1320 clamps the clamper main shark. The envelope is firmly gripped by rotating in the direction of the groove 1310. The clamper driving unit (not shown) may be implemented by a cam device, or may be implemented by various actuators. Naturally, the clamper 1300 may be configured in various ways.

The clamper 1300 is installed to be movable in a plurality of arcs around the center point 111 of the charging device frame 1100. Therefore, when one process is finished, the process moves sequentially.

6 is an enlarged view of the inlet opening device.

The inlet opening device 1300 is installed on the filling device frame 1100 to reciprocate the suction plate 1310 and the suction plate 1310 toward the bag 200 to adsorb the front surface 211 of the bag. Actuator 1320 is included. In addition, it further includes an air supply unit 1330 for supplying air to the open envelope (200).

Therefore, when the suction plate 1310 is pushed against the bag 200 transferred by the clamper 1200, the bag is folded by the bag 200 to the support 1340 located at the rear. Then, when the adsorption plate 1310 retreats, as shown in Figure 6, only the front surface 211 is sucked in a state attached to the adsorption plate 1310 to open the inlet.

In this state, when the air is sprayed from the air supply unit 1330, the front and rear are dropped over the entire inside of the envelope. In this state, the clamper 1200 transfers the bag to the liquid injection device 1400.

The liquid injection device 1400 includes a water tank 1410 and a supply nozzle 1420 for supplying water from the water tank 1410 to the bag. In addition, a pump for supplying the supply nozzle 1420 from the water tank 1410 and a controller for controlling the amount of water supplied are provided. Since such a configuration can be easily configured by those skilled in the art, a detailed description thereof will be omitted.

The bag 200 supplied with water to the bag from the liquid injection device 1400 is transferred to the pressing unit 1500 by the clamper 1200. At this time, the specific gravity of the absorber 120 is low to rise to the inlet side of the envelope 200. The pressing unit is a device for pressing it.

And a horizontal shaft 1540 supporting the support shaft 1530 in the horizontal direction, and a driving shaft 1520 supporting the horizontal shaft 1540 and coupled to an actuator (not shown).

An actuator (not shown) may be used as a pneumatic and hydraulic actuator, and may be driven by a cam device without using a separate power. The actuator moves the drive shaft 1520 in the longitudinal direction, whereby the pressing plate 1510 moves out of the inlet of the bag after pressing the absorber 1530.

Then, the clamper 1200 is moved to the bonding device 1600. At this time, the speed at which the absorber 1530 rises is low and does not immediately rise to the inlet side of the bag.

8 is a perspective view of the bonding apparatus.
