In other embodiments, the inner surface of the outer ring part 32 of the valve part 3 may be provided with at least one circumferentially arranged sealing groove and the radially outer surface of a portion of the tapping pipe 4 may be provided with at least one circumferentially arranged sealing rib to achieve a sealing fit between the tapping pipe 4 and the valve part 3. In some embodiments, the radially outer surface of the portion of the tapping pipe 4 and the radially inner surface of the outer ring portion 32 of the valve part 3 may be provided with at least one axially arranged stop groove 43 and stop rib 36, respectively, or the radially outer surface of the portion of the tapping pipe 4 and the radially inner surface of the outer ring portion 32 of the valve part 3 may be provided with at least one axially arranged stop rib and stop groove, respectively, to prevent rotational movement of the tapping pipe 4 relative to the valve part 3.

In other embodiments, not shown, the second sealing engagement portion of the valve part 3 may be configured as at least one sealing rib circumferentially disposed on an outer surface of the inner body portion 31 of the valve part 3 to sealingly engage with at least one sealing groove circumferentially disposed on a radially inner surface of a portion of the tapping pipe 4, or the second sealing engagement portion of the valve part 3 may be configured as at least one sealing groove circumferentially disposed on an outer surface of the inner body portion 31 of the valve part 3 to sealingly engage with at least one sealing rib circumferentially disposed on a radially inner surface of a portion of the tapping pipe 4. In some embodiments, the radially inner surface of the portion of the tapping pipe 4 and the radially outer surface of the inner body portion 31 of the valve part 3 may be provided with at least one axially arranged stop groove and stop rib, respectively, or the radially inner surface of the portion of the tapping pipe 4 and the radially outer surface of the inner body portion 31 of the valve part 3 may be provided with at least one axially arranged stop rib and stop groove, respectively, to prevent rotational movement of the tapping pipe 4 relative to the valve part 3.

In other embodiments, not shown, the valve part 3 may be substantially cylindrical and have on its radially outer surface a first and a second sealing engagement portion arranged on the lower and upper side, respectively, in the axial direction, for sealing engagement with the tubular body 2 and the tapping pipe 4, respectively. In such an embodiment, a first seal-fitting portion of the valve member 3 on the lower side in the axial direction is in seal-fitting engagement with the radially inner surface of the shoulder portion 22 of the pipe body 2, and the discharge pipe 4 is fitted over at least a portion of the valve member 3 radially outside and in seal-fitting engagement with a second seal-fitting portion of the valve member 3 on the upper side in the axial direction.

In other embodiments not shown, the tapping pipe 4 is configured to sealingly engage with the shoulder portion 22 of the pipe body 2, and may comprise a first and a second sealing engagement portion to sealingly engage with the shoulder portion 22 of the pipe body 2 and the valve member 3, respectively. For example, the radially outer surface of the tapping pipe 4 may be configured with a first seal-fitting portion to be sealingly fitted with the radially inner surface of the shoulder portion 22 of the pipe body 2, and the radially inner surface of the tapping pipe 4 may be configured with a second seal-fitting portion to be sealingly fitted with a corresponding seal-fitting portion of the radially outer surface of the valve member 3.

As shown in fig. 3, the top surface of the valve member 3 may be substantially flat, having an opening 37 therein and a valve plate 38 disposed in the opening 37. A part of the periphery of the valve plate 38 is spaced from the edge of the opening 37 by a substantially C-shaped slot, and another part of the periphery of the valve plate 38 is connected to the edge of the opening 37 so that the valve plate 38 can pivot about the other part in the axial direction. When the tube 2 is not squeezed, the valve plate 38 is in the initial position and the material contained in the tube 2 does not flow out of the valve member 3; when the body 2 is squeezed, the body forces the flap 38 to pivot out of the body 2 through the opening 37, and when the squeezing load on the body 2 is removed, the flap 38 can return to the initial position. It should be understood that the shape of the slot is not limited to a C-shape, but may be other shapes, such as a quadrilateral, a hexagon, etc., as desired. It should be understood that the number of slots is not limited to one, but may be more than one according to actual needs.

In some embodiments, the width of the slot is 0.1mm to 1 mm. Preferably, the width of the slot is about 0.5 mm. In some embodiments, the further portion of the periphery of the valve plate 38 is 0.5mm to 5mm in length. Preferably, the further portion of the periphery of the valve plate 38 is about 1mm in length.

As shown in fig. 5 to 8, in another embodiment according to the present invention, the packing hose 1' may include: a seal 6 ' arranged at the mouth 41 ' of the tapping pipe 4 ', which seal 6 ' is arranged for sealing the mouth 41 '; and a sealing member removing part 51 ' provided on the cap 5 ' to be at least partially form-fitted with the sealing member 6 ' such that when the cap 5 ' is reversed on the sealing member 6 ' and the sealing member removing part 51 ' is fitted with the sealing member 6 ', the sealing member 6 ' is rotated by the rotation of the sealing member removing part 51 ' so that the sealing member 6 ' is completely or partially separated from the spout 41 ' after being rotated by a certain angle to open the spout 41 ' of the tapping pipe 4 '. The certain angle may for example be between 180 ° and 360 °. The seal removing part 51 'may be provided at the top, side, or the like of the tube cover 5'. The shape of the seal member 6 'and/or the seal member-removed portion 51' may be square, triangular, oval, shaped (e.g., flower-shaped), and the like. It should be understood that the seal member 6 'and the seal member removing portion 51' may have at least partial shapes that match each other so that the rotation of the seal member removing portion 51 'can rotate the seal member 6'. The shape of the seal 6 'and the seal removing portion 51' may also be set to match perfectly.

From the above description, it is clear that the packing hose according to the present invention effectively reduces the risk of contamination of the material body contained in the packing hose through the spout, and also reduces the risk of leakage of the material body contained in the packing hose through the spout when the packing hose is toppled or tipped.

Although exemplary embodiments of the present disclosure have been described, it will be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without substantially departing from the spirit and scope of the present disclosure.
