在本发明另一实施例中，参阅图4至图7，管头12的顶部设有一柱塞13，管头12的端面开设有若干通孔121，管头12的端面向外延伸一管头柱环14，柱塞13位于管头柱环14内，通孔121与管头12环柱的内腔连通。管体11的内容物可以从通孔121出来进入管头12环柱的内腔，便于管体11的内容物尽可能地由阀体22排出，避免内容物进入滑动座21其它位置。
在本发明另一实施例中，阀体22开设有出料孔221，出料孔221的边沿朝向于管头12延伸形成有封堵环224，封堵环224与柱塞13配合。该结构便于柱塞13端部伸入封堵环224内，实现可靠密封，避免内容物由出料孔221漏出。
在本发明另一实施例中，阀体22于出料孔221背离于管头12一端的边沿延伸形成有出液管227，出液管227与涂抹头30连通。该结构便于将内容物导引至涂抹头30的端面，而不是停留在涂抹头30的内部。
在本发明另一实施例中，阀体22的出料孔221的边沿向外延伸设有第一柱环225与第二柱环226，管头柱环14伸入第一柱环225与第二柱环226之间的区域。该结构便于引导阀体22与滑动座21，让阀体22与滑动座21在预定方向移动，而不会产生歪斜。在将外盖40拔出时，让外盖40更稳定地带起滑动座21，实现柱塞13离开于出料孔221。
在本发明另一实施例中，管头柱环14的内表面凸设有用于与第一柱环225的外表面抵接配合的密封环141。该结构容易成型，让管头柱环14与第一柱环225之间可靠密封，避免内容物从两者之间的间隙漏出。
在本发明另一实施例中，请参阅图2、图7至图9，滑动座21的外表面设有台阶211，外盖40的内表面设有用于与台阶211抵接配合的抵接台41，在将外盖40盖设于管头12时，抵接台41抵接于台阶211以使滑动座21向下移动闭合阀体22。在不使用时，通过将外盖40盖在管头12上，抵接台41与台阶211抵接，让滑动座21复位，闭合阀体22，避免内容物漏出。具体地，两个抵接台41对称分布于外盖40内表面，滑动座21外表面对称设有两个台阶211，抵接台41与台阶211一一对应配置，在将外盖40盖设于管头12时，让安装套可靠地跟随外盖40移动。
在本发明另一实施例中，滑动座21的口部内沿设有卡扣213，管头12的侧壁对应开设有预定宽度的限位槽122，卡扣213扣接于限位槽122内，限位槽122的宽度为滑动座21的上下移动范围。该结构容易装配，便于调节滑动座21相对于管头12的位置。具体地，限位槽122为凹设于管头12侧壁的环形槽，卡扣213可沿轴向方向移动，卡扣213与环形槽的两个内侧壁配合以限定滑动座21相对于管头12的移动范围。
在本发明另一实施例中，外盖40的口部内沿设有扣线42，管头12的侧壁对应开设有与扣线42扣接的扣位123，当外盖40盖设于管头12时，扣线42扣接于扣位123，滑动座21处于闭合状态。该结构容易成型，通过扣线42与扣位123配合，让外盖40限位于管头12。具体地，扣线42的数量至少为二，扣线42均布于外盖40口部内沿，扣位123的数量等于扣线42的数量，扣位123为凹设于管头12的侧壁的弧形槽，扣线42扣接于扣位123时，让外盖40可靠地限位于管头12。
在本发明另一实施例中，参阅图4、图5、图8，在拔出外盖40时，扣线42分离于扣位123，外盖40在拔开向上移动的过程中扣线42抵接于滑动座21的口部边沿，以带动滑动座21向上移动打开阀体22。扣线42的内径小于滑动座21其中一端口部外径，在拔出外盖40的过程，扣线42与滑动座21的口部干涉，借助拔开外盖40的动作将滑动座21同时带开，拔开外盖40后可以直接使用。
在本发明另一实施例中，涂抹头30为软质刷具。具体地，软质刷具是热塑性弹性体（TPE）或硅胶的软质刷具。
在本发明另一实施例中，请参阅图2至图4，涂抹头30可以为毛刷、眼线笔、棉棒、植绒头、滚珠、海绵头、软胶舌片、粉扑头、唇膏头、按摩头等各种形式的涂抹头。
在本发明另一实施例中，涂抹头30包括固定块31及安装于固定块31一侧的涂抹部32，固定块31抵接于阀体22上。该结构容易成型与装配。
在本发明另一实施例中，滑动座21的口部边沿向内延伸形成有抵接部214，抵接部214抵接于固定块31以使固定块31固定于阀体22上。该结构容易装配，在将涂抹头30的固定块31放置于阀体22的一侧，再将阀体22固定于滑动座21内，抵接部214与阀体22夹持固定块31，使得涂抹头30固定于阀体22。具体地，固定块31呈饼状，固定块31有一定硬度，抵接部214呈环状，抵接部214与阀体22共同夹持固定块31以固定涂抹头30。涂抹部32穿过安装筒的口部，设于固定块31的涂抹部32不容易掉出，让涂抹部32可靠耐用。
在本发明另一实施例中，参阅图4、图5，滑动座21内设有用于供阀体22扣合的卡槽212。该结构便于阀体22扣合安装于滑动座21内。具体地，阀体22包括板体222及与板体222的边沿延伸形成的环形壁223，卡槽212的形状与环形壁223的形状相适配，将环形壁223放置于卡槽212，即可让阀体22限位于滑动座21内。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
