Abstract

The present invention relates to a pouch forming apparatus comprising: a die, in which forming grooves are formed with a partition wall therebetween; and a punch member provided with a punch, which is configured to be inserted into each of the forming grooves to press the pouch film to form a pair of accommodation grooves in the pouch film, wherein the forming groove comprises a vertical space disposed above a forming groove bottom part connected to the partition wall and an inclined space connected to the vertical space and formed by providing an inner wall facing the partition wall, the inner wall defining an inclined surface .

First claim

1 . A pouch forming apparatus comprising:
a die, defining forming grooves with a partition wall therebetween along a first surface; and a punch member including a punch, the punch member configured to be inserted into each of the forming grooves to press a pouch film to form a pair of accommodation grooves in the pouch film,
wherein the forming groove comprises a vertical space disposed above a forming groove bottom part and adjacent to the partition wall, and the forming groove further comprises an inclined space connected to the vertical space, the inclined space defined by an inner wall defining an inclined surface facing the partition wall,
the punch comprises a vertical block configured to be inserted into the vertical space to press the pouch film, and the punch further comprising an inclined block configured to be inserted into the inclined space to press the pouch film, wherein a surface of the inclined block, which faces the inner wall, is provided as an inclined surface, and
an inner surface of the accommodation groove, which is disposed between the inclined surface of the inclined space and the inclined surface of the inclined block, is formed into an accommodation groove inclined surface.

2 . The pouch forming apparatus of claim 1 , further comprising a coupling means configured to detachably couple the inclined block to the vertical block.

3 . The pouch forming apparatus of claim 2 , wherein the coupling means comprises a coupling groove formed in the vertical block and a coupling protrusion formed on the inclined block and configured to be coupled to the coupling groove.

4 . The pouch forming apparatus of claim 2 , wherein the inclined block comprises a first block having an inclined surface at a first angle, and a second block having an inclined surface at a second angle, angle, and
a block having an inclination angle corresponding to the inclined surface of the inclined space among the first and second blocks is configured to be coupled to the vertical block.

5 . The pouch forming apparatus of claim 1 , wherein the inclined block has an inclination angle of between 30° to 60°.

6 . The pouch forming apparatus of claim 1 , further comprising a fixing member configured to fix the inclined block to the punch member.

7 . The pouch forming apparatus of claim 1 , wherein a finishing member configured to close a gap between the vertical block and the inclined block is provided between the vertical block and the inclined block.

8 . The pouch forming apparatus of claim 7 , wherein the finishing member comprises a coupling part configured to be inserted between the vertical block and the inclined block and a support part configured to support each of bottom surfaces of the vertical block and the inclined block, and
a bottom surface of the support part is disposed on the same horizontal line as the-bottom surfaces of the vertical block and the inclined block.

9 . A pouch forming method comprising:
disposing a pouch film on a die, the die comprising forming grooves formed with a partition wall therebetween along a top-surface thereof, wherein each of the forming grooves is partitioned into a vertical space disposed above a forming groove bottom part connected to the partition wall, and the die further comprising an inclined space connected to the vertical space and formed by providing an inner wall facing the partition wall, the inner wall defining an inclined surface; preparing a punch member comprising a punch, wherein the punch comprises a vertical block and an inclined block, and an outer surface of the inclined block, which corresponds to the inclined surface of the inclined space, is provided as an inclined surface; and inserting the punch member comprising the punch into each of the forming grooves to press the pouch film disposed on the die to form a pair of accommodation grooves in the pouch film, wherein a wall of the accommodation groove facing the partition wall is formed into an inclined surface by the inclined surface of the inclined block and the inclined surface of the forming groove.

10 . The pouch forming method of claim 9 , wherein, in the preparing step, the inclined block comprises a first block having an inclined surface at a first angle, and a second block having an inclined surface at a second angle, and
a block having an inclination angle corresponding to the inclined surface of the forming groove among the first and second, blocks is coupled to the vertical block.

11 . The pouch forming method of claim 10 , wherein the preparing step further comprises a process of fixing the inclined block to the punch member with a fixing member when the inclined block is coupled to the vertical block.
