本申请的有益效果是：
1)本申请包括外盖、内盖、内塞和管体，外盖和内盖固定配合形成盖组合，内塞通过卡环固定且密封配合于管体的注肩，从而防止料体的泄漏，盖组合盖合于管体时，内盖的结合部与管体的注肩之间通过螺纹配合，外盖的出料管与内塞的外圈之间通过密封环过盈配合而有效防止管体内的料体流入外盖与内盖之间的空腔中；
2)本申请中外盖的出料管与内塞的内柱之间形成出料通道，当盖组合与注肩旋紧时，出料通道被密封结构阻挡，此时软管处于关闭状态，因此即使挤压管体也无法将料体挤出，提高了软管的安全性；使用时，以盖组合与注肩旋紧位置为起点，旋转盖组合一定角度后，密封结构脱离盖组合和内塞之间的出料通道，挤压管体使管体中的料体通过出料通道流出供用户使用，此时软管处于打开状态，因此使用本软管时，用户无需将盖组合从管体上取下，提高了软管使用的便捷度，而且消除了盖组合掉落造成丢失和污染的风险；在整个使用过程中，盖组合始终盖合于管体上，因此减少了管体中料体的挥发损失；
3)在内盖与注肩之间设有相互限定的卡合机构，卡合机构相互配合的凸点和卡槽，卡合机构用于限定软管在打开状态或关闭状态时内盖注肩之间的相互位置，且能够防止盖组合与管体分离，同时也更便于用户的操作；为了进一步增加盖组合旋转过程的稳定性，在内盖的结合部上还设有第二卡点，第二卡点始终顶住注肩，防止盖组合在旋出时产生晃动。

实施例：如图1-16所示，一种挤压出料式软管，包括盖组合、内塞30和管体40，管体40具有用于容纳料体的主体41和从主体41伸出的注肩42， 内塞30密封且固定地插设于注肩42，盖组合装配于注肩42，内塞30与盖组合之间设有密封结构，且内塞30与盖组合之间形成出料通道24，当盖组合旋紧于注肩42时，即通过扭力朝向同一方向(顺时针或逆时针)转动盖组合达到指定位置，此时继续朝向该同一方向无法转动盖组合，密封结构封堵住出料通道而使主体41中料体无法通过出料通道24流出，当盖组合从旋紧位置被沿着旋紧方向的反方向旋转后，密封结构脱离出料通道而使主体41中料体能够通过出料通道24流出。
其中，主体41用于容纳液体或半固体料体，例如护手霜、乳液、护肤液等等，与传统的包装软管相比，本申请增加了内塞30，内塞30插入注肩42的开口中，盖组合与注肩42之间通过螺纹或卡扣配合在一起，当盖组合与注肩42旋紧时，盖组合和内塞之间的出料通道24被密封结构阻挡，此时软管处于关闭状态，因此即使挤压管体40也无法将料体挤出，提高了软管的安全性；使用时，从盖组合与注肩42旋紧位置开始旋转盖组合，使盖组合旋转一定角度而内塞与管体固定不动，一定角度理论上可以为0°至360°之间的任意角度，在实际应用中可选择45°、90°、180°等符合人们使用习惯的角度，使密封结构脱离盖组合和内塞之间的出料通道24，挤压管体使管体中的料体通过出料通道24流出供用户使用，此时软管处于打开状态，因此使用本软管时，用户能够单手打开使用，提高了软管使用的便捷度，而且无需将盖组合从管体上取出，而消除了盖组合掉落造成污染的风险。
如图1和图3所示，盖组合包括外盖10以及固定安装于外盖10中的内盖20，内盖20装配于注肩42且内盖20与注肩42之间设有相互限定的卡合机构，密封结构固定设于外盖10和内塞30中至少一个上，外盖10和内塞30之间形成出料通道24。当盖组合装配于注肩42上，但两者没有旋紧时，外盖10与内塞30之间具有间隙，该间隙即为出料通道24，密封结构处于出料通道中，如图1-2所示，当内盖20旋紧于注肩42时，密封结构使外盖10和内塞30之间过盈配合，而将出料通道堵住；如图13-16所示，当内盖被旋转一定角度后，外盖相对于内塞上升了一定的距离，使外盖上的密封结构离开了内塞，或使内塞上的密封结构离开了外盖，出料通道24被打开，卡合机构用于限定软管在打开状态或关闭状态时内盖20与注肩42之间的相互位置，防止盖组合与管体 分离，同时也更便于用户的操作；密封结构固定设于外盖10上，或内塞30上，或外盖10和内塞30上。
如图3-4所示，外盖10沿轴向方向延伸形成出料管11，出料管11的第一端设有出料口14，出料管11的第二端设有进料口15，内盖20沿轴向方向延伸形成结合部21，当内盖20固定安装于外盖10内时，出料管11插设于结合部21内，结合部21装配于注肩42。外盖10类似龟壳状结构，在外盖10的中心部位沿轴向方向向内部延伸形成中空的出料管11，出料管的出料口14延伸至外盖表面，料体最终通过此出料口14出料供用户使用的，如图5-7所示，内盖20的表面结构与外盖10类似，因此外盖10刚好覆盖于内盖20表面，两者之间可通过卡扣卡合固定或胶水粘粘固定，两者组装好后形成盖组合，内盖20的中心部位沿轴向方向向内部延伸形成结合部21，出料管11位于结合部21内，盖组合与管体组装时，结合部21的内侧壁与注肩42之间通过螺纹或卡扣配合在一起。
如图8-11所示，内塞30为圆环状结构，且内塞30上至少设有一个出料孔33，管体中的料体通过出料孔33进入出料通道24，内塞30外环的圆周沿轴向方向延伸形成外圈31，内塞30内环的圆周沿其轴向方向延伸形成内柱32，外圈31与内柱32之间具有插槽34，出料孔33与插槽34相互连通。外圈31设置于内柱32的径向外侧，如图1和2所示，外圈31与注肩42配合，出料管11插入插槽34中，即内柱位于出料管11内部，外圈31位于出料管外侧，出料管11与外圈31的内侧壁紧密配合，出料管11与内柱32之间具有间隙即出料通道，密封结构位于出料管11与内柱32之间，内柱32的顶面为封闭结构，因此在密封结构的配合下内柱32能够密封住外盖10的出料口14。
如图8所示，外圈31的外侧壁与注肩42的内侧壁之间至少设有一圈卡环36，卡环36用于令外圈31与注肩42固定卡合在一起，卡环36固定设于外圈31的外侧壁或者注肩42的内侧壁。外圈31的外侧壁沿其径向向外延伸形成卡环36，或注肩42的内侧壁沿其径向向内延伸形成卡环36，卡环36的个数以2-4个为佳，外圈与注肩通过弹性卡环36卡合在一起，装配完毕后就很难分离开；当然卡扣也可以变形为凸点、卡槽等常用的装配结构。
如图1和图2所示，出料管11插入插槽34中，出料管11的外侧壁与外 圈31的内侧壁之间至少设有一圈第二密封环13，第二密封环13固定设于出料管11的外侧壁或外圈31的内侧壁。外圈31的内侧壁沿其径向向内延伸形成第二密封环13，或出料管11的外侧壁沿其径向向外延伸形成第二密封环13，第二密封环的个数以2-4个为佳，外圈与出料管之间通过若干圈平行布置的第二密封环过盈配合，以防止料体流向内盖和外盖之间的空腔内。
如图1所示，内柱32位于出料管11中，内柱32和出料管11之间形成出料通道24，密封结构固定设于内柱32的外侧壁或出料管11的内侧壁。内柱32与出料管11之间具有一定间隙即为出料通道24。
可选地，密封结构包括第一密封环12和第三密封环35，当盖组合旋紧于注肩42时，第一密封环12靠近出料口14并将出料口14密封，第三密封环35靠近进料口15并将进料口15密封。第一密封环12和第三密封环35可以设于内柱32或出料管11上，如第一密封环12和第三密封环35皆设于出料管11时，出料管11的内侧壁在靠近出料口14和靠近进料口15处分别沿径向向内延伸形成一圈第一密封环12和第三密封环35，当软管处于关闭状态时，第一密封环12和第三密封环35皆过盈配合于内柱，而将出料通道24堵住；或第一密封环12和第三密封环35皆设于内柱32的外侧壁时，内柱32的外侧壁上下两端附近分别沿径向向外延伸形成一圈第一密封环12和第三密封环35，当软管处于关闭状态时，第一密封环12和第三密封环35皆过盈配合于出料管11，而将出料通道24堵住；亦或如图1所示，第一密封环12位于出料管的出料口附近，第三密封环35位于内柱32的下端附近，总之，当软管处于关闭状态时，第一密封环12和第三密封环35分别密封于出料口14和进料口15，防止料体从出料通道24中流出，在出料口和进料口各设一道密封结构，提高了软管的密封性能。
如图12所示，注肩42的外侧壁上设有两个相互间隔的第三卡点44，如图7所示，结合部21的内侧壁上设有两个相互间隔的第一卡点22和第二卡点23，第一卡点22与第三卡点44能够相互卡合，第二卡点23抵靠于注肩42的外侧壁。
可选地，第二卡点23为凸点，第一卡点22和第三卡点44为相互配合的凸点或卡槽。内盖20与注肩42之间的卡合机构为第一卡点22和第三卡点44， 如图12所示，注肩42的外侧壁设有外螺纹43，内盖与注肩螺纹结合，在外螺纹43上设有两个相互间隔的第三卡点44，且两个第三卡点44不在同一水平面上，以第三卡点44为卡槽为例来说明，内盖的结合部21内侧壁上设有一第一卡点22，则第一卡点22为凸点，当第一卡点22刚好卡入下方的第三卡点44上，内盖20的下表面贴合于管体40的上表面，如图1-2所示，此时内盖20与注肩42旋紧，第一密封环12和第三密封环35分别密封于出料口和进料口，软管处于关闭状态；在此位置的基础上旋转盖组合一定角度例如180°后，第一卡点22卡入上方的第三卡点44上，盖组合整体上移，如图13-14所示，内盖20的下表面脱离管体40的上表面，第一密封环12脱离内柱32，第三密封环35脱离出料管11，出料通道24被打开，即软管处于打开状态，此时挤压管体，管体中的料体通过内塞上的出料孔33进入出料通道24，最后通过出料口14出料供用户使用。为了进一步增加盖组合旋转过程的稳定性，在内盖20的结合部上还设有第二卡点23，第二卡点23始终顶住注肩42，防止盖组合在旋出时产生晃动。
本申请的操作过程：包括以下步骤：
步骤一：如图1-2所示，起始时内盖20与注肩42旋紧，第一密封环12和第三密封环35分别密封于出料口和进料口，出料通道24被封闭，即软管处于关闭状态，此时内盖20的第一卡点22刚好卡入注肩42下方的第三卡点44上，内盖20的下表面贴合于管体40的上表面；
步骤二：在旋紧位置的基础上，用户旋转盖组合一定角度例如180°后，第一卡点22卡入注肩42上方的第三卡点44上，盖组合整体上移，如图13-14所示，内盖20的下表面脱离管体40的上表面，第一密封环12脱离内柱32，第三密封环35脱离出料管11，出料通道24被打开，即软管处于打开状态；
步骤三：用户挤压管体40，管体40中的料体通过内塞上的出料孔33进入出料通道24，最后通过出料口14出料供用户使用，使用完成后，用户再次反方向旋转盖组合，使得内盖20与注肩42旋紧恢复至起始位置。
应当指出，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
