Description

  The present invention relates to an operation container capable of moving up and down a holding portion that holds a rod-like content by rotating an outer cylinder portion.

  Conventional containers that contain stick-like contents such as lipstick, lip balm, or stick-type glue have a holding part that holds the stick-like contents, and are held by rotating the outer cylinder part when in use. An operation container is known which can move a portion and thereby feed out the rod-shaped contents hidden inside the cylindrical wall to the outside. For example, Patent Document 1 includes an outer cylinder having a spiral groove on an inner peripheral surface, a protruding member provided with an engaging protrusion that slidably engages with the spiral groove, and a holder that holds a rod-shaped content. An operation container is shown in which the protruding member and the holder can be moved up and down by rotating the outer cylinder.

JP-A-8-150019

  In the spiral groove in the conventional operation vessel, the interval between adjacent grooves is constant. That is, the distance that the holding part moves when the outer cylinder part makes one rotation is always constant from the lowest point to the highest point of the holding part. By the way, in such an operation container, for example, stick-type paste may be used by spreading the stick-shaped contents against the application destination, but the stick-shaped contents are more than necessary from the cylindrical wall. If it is drawn out, it may break during use. In such a case, by reducing the distance between adjacent grooves in the spiral groove and reducing the amount of movement of the rod-shaped contents per one rotation of the outer cylinder portion, the rod-shaped contents are not unnecessarily drawn out. It is conceivable to adopt a means to do. However, in this case, it is necessary to rotate the outer cylinder part many times in order to feed out the rod-like contents hidden inside the cylindrical wall, which takes time and effort. For this reason, there is a demand for delivering this quickly in the first half of the moving range of the rod-shaped contents and slowly delivering it in the second half. On the other hand, depending on the application, there is also a demand for slowly feeding out the amount of movement of the rod-like contents in the first half of the moving range and for quickly feeding it out in the second half.

  The present invention is intended to solve such a demand, and the amount of movement of the holding portion corresponding to the rotation of the outer cylinder portion can be changed according to the type and usage of the rod-shaped contents. The purpose is to provide a handling vessel.

The present invention includes an inner cylindrical portion having a slit extending in the axial direction, an outer cylindrical portion having a spiral groove on an inner peripheral surface and provided rotatably with respect to the inner cylindrical portion outside the inner cylindrical portion, A holding portion having a guide projection for engaging with the spiral groove through the slit and holding the rod-shaped contents, and the holding portion being moved up and down relative to the inner cylinder portion by rotating the outer cylinder portion A container,
The outer cylinder portion is connected in series with the first cylinder having a first spiral groove that constitutes a part of the spiral groove, and an interval between adjacent grooves is the first cylinder. A second cylinder having a second spiral groove that is the same as or different from the spiral groove, and positioned on the outside of the first cylinder and the second cylinder and rotated with respect to the first cylinder and the second cylinder It is an operating container provided with the outer case connected impossible.

The first cylinder has a first convex portion protruding in the axial direction or a first concave portion recessed in the axial direction,

Having a second vertical rib continuous to the vertical rib;
The outer case is an inner vertical rib that fits the first vertical groove and the second vertical groove on the inner peripheral surface of the outer case, or the first vertical rib and the second vertical rib on the inner peripheral surface of the outer case. It is preferable to have an inner longitudinal groove that fits into the rib.

The inner cylinder portion has a bulging portion protruding outward in the radial direction,
