  • the end face of the cut surface perpendicular to the longitudinal direction is formed into an outwardly convex curved surface.
  • This increases the volume of the container body.
  • the mechanical strength against pressure from the inside of the container body is increased.
  • the inventors of the present invention have found that when the content is discharged from a conventional elastically deformable fluid container, the peripheral wall of the container is pressed, thereby deforming the convex curved surface into an inwardly convex curved surface. Focusing on the phenomenon, it was discovered that the cause of the excessive extrusion of the fluid contained in the container was a sudden and large change in the shape of the peripheral wall, including the opposite direction of the convex shape.
  • the inventors of the present invention came up with the technical idea of reducing the sudden and large shape change of the peripheral wall when the container body is pressed to take out the contents.
  • the inventors of the present invention dared to sacrifice the volume of the fluid container, and in the peripheral wall of the main body, when two surfaces with the largest projected area are used as main surfaces, at least
  • the present inventors have come up with the configuration of the first invention in which a concave portion that protrudes inward is formed on either one of the main surfaces. If a part of the main surface of the container body is configured as a recessed portion, the recessed portion can be pressed by pressing a finger against the recessed portion when taking out the contents from the inside of the container body.
  • the probability of occurrence of a phenomenon in which the fluid, which is the contents, excessively flows out is reduced compared to the case where the container body does not have the concave portion.
  • One reason for this is considered to be the fact that the container body with the concave portion has less room for deformation by pressing than the case where the container body does not have the concave portion.
  • the concave portion is pressed, the deformation of the container body only increases the degree of the concave shape, and the direction of the concave shape does not change. The fact that no shape change occurs is believed to be another factor.
  • the presence of the concave portion sacrifices the volume of the container body, it reduces the possibility that the contents will be extruded excessively. does not decrease, but rather increases in some cases. As described above, according to the configuration of the first invention, it is possible to reduce the possibility that the contents will be extruded excessively.

Further, since the concave portion is formed in the reverse curved peripheral wall portion, it can be easily recognized by the user. As a result, the user is more likely to use the concave portion, so that the possibility of the contents being pushed out excessively can be reduced.

  • the user removes the lid from the fluid container, and then takes out the contents from the container body.
  • the inventors of the present invention also paid attention to the operation of gripping the lid and the operation of removing the lid. Since the lid is a relatively small part, for example, during the operation of removing the lid, or after removing the lid, during the operation of placing it on a flat surface such as a desk, it may roll and fall to the floor. situation may arise. In order for the user to make a smooth transition to the next step of taking out the contents, it is necessary to grip the lid more securely to avoid the above-described inconvenient situations.
  • the user can fix his or her fingers on the upper surface of the outer member formed in a partially spherical shape when gripping the fluid container. Furthermore, since the inner member can be visually recognized through the outer member, by directing the user's viewpoint toward the inner member positioned inside the outer member, the inner member positioned inside the outer member can be grasped. Since it can be generated, the outer member can be gripped more securely than when the outer member is opaque. This reduces the likelihood of the above-described adverse situations occurring. Further, when the fluid container has a size that can be gripped by a human hand, for example, one finger is fixed to the upper surface of the lid and the other finger is attached to the concave portion of the container body.
  • the fluid container By fixing the fluid container to the two fingers, the fluid container can be held securely by pinching it between two fingers. Furthermore, when the lid is removed from the container body, by placing the lid with its upper surface facing downward, only the peripheral part of the partially spherical surface of the upper surface comes into contact with the placement location, so the placement location becomes dirty. Even if the container body is used, the lid body can be kept clean by engaging the lid body with the container body and cleaning only the periphery of the upper surface of the lid body after use. . Furthermore, the inventors of the present invention considered that it is a weight factor to take out the contents gradually with a relatively small force in order to take out an appropriate amount of the contents from the fluid container.

  • the outer member filaments are arranged outside the peripheral wall of the base of the inner member, and outside the peripheral wall of the tip not actually placed.

It has a configuration that allows easy visual recognition.
  • the maximum diameter of the tip contour is less than the minimum diameter of the base contour (hereinafter referred to as (referred to as the "diameter condition") reduces the distance between the perimeter of the base and the filament, making the filament easier to see for the user.
  • the filaments are not substantially arranged outside the peripheral wall of the distal end portion, the user can visually recognize the distal end portion of the inner member relatively clearly. Furthermore, by satisfying the diameter condition, the distance between the outer circumference of the tip portion and the outer circumference of the outer member is larger than when the diameter condition is not satisfied. , the tip is configured to be more clearly visible. As described above, when the inner member and the outer member are engaged with each other, the filaments of the outer member and the tip of the inner member are easily visible from the outside. Accordingly, when gripping the fluid container, the user can more reliably grip the fluid container while being conscious of the inner member of the lid. In addition, when the user removes the lid from the container body, the user can relatively easily recognize the filaments and bring his or her finger into contact with the filaments.

Therefore, when the user grips the vicinity of the lower end of the lid with fingers and rotates the lid relative to the container body to remove the lid, the fingers of the user gripping the lid come into contact with the container body. or the contact area becomes relatively small. This means that the user's fingers are lessened by unnecessary friction that does not affect the removal of the lid. This allows the user to more effectively remove the lid from the main body.
