In other embodiments, the inner surface of the outer ring portion 42 of the valve part 4 may be provided with at least one circumferentially arranged sealing groove and the radially outer surface of a portion of the tapping pipe 6 may be provided with at least one circumferentially arranged sealing rib to achieve a sealing fit between the tapping pipe 6 and the valve part 4. In some embodiments, the radially outer surface of the portion of the tapping pipe 6 and the radially inner surface of the outer ring portion 42 of the valve part 4 may be provided with at least one axially arranged stop groove 63 and stop rib 46, respectively, or the radially outer surface of the portion of the tapping pipe 6 and the radially inner surface of the outer ring portion of the valve part 4 may be provided with at least one axially arranged stop rib and stop groove, respectively, to prevent rotational movement of the tapping pipe 6 relative to the valve part 4.

In other embodiments, not shown, the second sealing engagement portion of the valve member 4 may be configured as at least one sealing rib circumferentially disposed on an outer surface of the inner body portion 41 of the valve member 4 to sealingly engage with at least one sealing groove circumferentially disposed on a radially inner surface of a portion of the discharge pipe 6, or the second sealing engagement portion of the valve member 4 may be configured as at least one sealing groove circumferentially disposed on an outer surface of the inner body portion 41 of the valve member 4 to sealingly engage with at least one sealing rib circumferentially disposed on a radially inner surface of a portion of the discharge pipe 6. In some embodiments, the radially inner surface of the portion of the tapping pipe 6 and the radially outer surface of the inner body portion 41 of the valve part 4 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 6 and the radially outer surface of the inner body portion 41 of the valve part 4 may be provided with at least one axially arranged stop rib and stop groove, respectively, to prevent rotational movement of the tapping pipe 6 relative to the valve part 4.

In other embodiments, not shown, the valve part 4 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 3 and the tapping pipe 6, respectively. In such an embodiment, a first seal-fitting portion of the valve member 4 on the lower side in the axial direction is in seal-fitting engagement with the radially inner surface of the shoulder portion 32 of the pipe body 3, and the discharge pipe 6 is fitted over at least a portion of the valve member 4 radially outward and in seal-fitting engagement with a second seal-fitting portion of the valve member 4 on the upper side in the axial direction.

In other embodiments, not shown, the spout 6 is configured to sealingly engage the shoulder portion 32 of the body 3, and may include first and second sealingly engaging portions to sealingly engage the shoulder portion 32 of the body 3 and the valve member 4, respectively. For example, the radially outer surface of the tapping pipe 6 may be configured to have a first seal-fitting portion to be sealingly fitted with the radially inner surface of the shoulder portion 32 of the pipe body 3, and the radially inner surface of the tapping pipe 6 may be configured to have a second seal-fitting portion to be sealingly fitted with a corresponding seal-fitting portion of the radially outer surface of the valve member 4.

As shown in fig. 5, the top surface of the valve member 4 may be substantially flat, having an opening 47 therein and a valve plate 48 disposed therein. A part of the periphery of the valve sheet 48 is spaced apart from the edge of the opening 47 by a substantially C-shaped slot, and another part of the periphery of the valve sheet 48 is connected to the edge of the opening 47 so that the valve sheet 48 can pivot about the other part in the axial direction. When the tube 3 is not squeezed, the valve plate 48 is in the initial position and the material contained in the tube 3 does not flow out of the valve element 4; when the tube 3 is squeezed, the body forces the flap 48 to pivot out of the tube 3 through the opening 47, and when the squeezing load on the tube 3 is removed, the flap 48 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 48 is 0.5mm to 5mm in length. Preferably, the further portion of the periphery of the valve plate 48 is about 1mm in length.

From the above description it is clear that the packaging tube according to the invention effectively reduces the risk of the material body being contaminated when the packaging tube is not unsealed, and that the removal process of the sealing element is convenient and fun.
