- the arranged shape is obtained (see FIG. 7C).
- the joining ridgeline 99 between the squeeze surface portion 96 and the diagonal connecting surface portions 98 on both sides is provided to extend in the vertical direction in a curved state, and the width of the squeeze surface portion 96 ends at the upper end of the trunk portion 93. By doing so, it is joined to the shoulder portion 95 integrally.
- the fixed discharge squeeze container 90 of this 5th Embodiment which has the above-mentioned structure, by pressing a thumb against the squeeze surface part 96 and adding squeezing force, for example, the container main body 91 is always squeezed with a constant deformation amount. Therefore, the same effect as the fixed discharge squeeze container 10 of the first embodiment is exhibited.
- the present invention is not limited to the above embodiments, and various modifications can be made.
- the position where the squeeze position guide part is provided and the position where the squeeze operation is performed are not necessarily the center part of the squeeze surface part, and the squeeze surface part can be squeezed at an arbitrary position to perform the squeeze operation.
- the squeeze deformation amount of the container body during repeated squeeze operations is regulated so that there is no variation, and a constant amount of liquid is contained. It can be discharged one by one.
