The upper and lower protrusions 19 and 20 protruding from the top and bottom of the ring stand vertically. Since the tip of the upper protrusion 19 is in contact with the back surface of the cap top wall 17, and the tip of the lower protrusion is in contact with the upper surface of the container body shoulder 3, the cap is pushed up by the rising of both protrusions, and the container is lifted up. The second engagement protrusion 9 of the cap inner peripheral wall 8 that engages with the lower surface of the first engagement protrusion 5 of the body mouth and neck is removed.

"Example" The drawings will be described below. Reference numeral 1 indicates a container body. The container body has a mouth and neck part 4 standing upright from the upper end of the body part 2 via a shoulder part 3, and a first engaging protrusion 5 is provided around the approximately middle part of the mouth and neck part.

The cap 6 has an inner circumferential wall 8 extending vertically from the back surface of the top wall 7, and a second engagement protrusion 9 disposed around the inner periphery of the lower end thereof, and an outer circumferential wall 10 extending vertically from the outer circumferential edge of the top wall. An inward flange 11 is attached to the lower end.
First through holes 12, 12 are bored at least in the left and right opposing positions of the inward flange.
Second through holes 13, 13 are bored in the intermediate portion of the outer circumferential wall portion above the inward flange portion having the through holes. As shown in FIG. 1, the inner circumferential wall 8 is fitted onto the outer surface of the mouth and neck, and its second engaging protrusion 9 is engaged with the lower surface of the first engaging protrusion 5, and the inward flange 11 is It is provided so as to be located above the shoulder portion 3. Reference numeral 14 is a packing, which is fitted to the back surface of the top wall portion inside the inner circumferential wall. Since it is difficult to integrally mold the cap, both the upper and lower members 6 are required, as can be understood from FIG.
Formed by fitting a and 6b.

The upper member 6a has a top wall 7 and an inner circumferential wall 8, and the outer circumferential wall 10 has an upper half cylinder portion 10a above a plane along the lower edge of the second through hole 13. Also lower member 6
b has a lower half cylindrical portion 10b below the plane along the lower edge of the second through hole 13 and an inward flange 11, and from the inner surface of the upper end of the lower half cylindrical portion, the second through hole 13 formation For this purpose, a plurality of fitting pieces 10c are erected to be fitted to the inner surface of the lower part of the upper half cylinder which does not have a cutout and is bored at the lower part of the upper half cylinder at the opposite position. The upper and lower half-cylindrical parts 10a and 10b are arranged such that the upper end surface of the lower half-cylindrical part is brought into contact with the lower end face of the lower part of the upper half-cylinder, and the fitting piece 10c is suitably engaged with the inner surface of the lower part of the upper half-cylinder. Join together with adhesive.

An operating member 15 is attached to the cap.
The operating member has an elastic ring 16 fitted on the inner surface of the outer circumferential wall of the cap, and push buttons 17 are attached to the outer surface of the ring and project outward from the second through holes 13. Further, from both upper and lower edges of the elastic ring portion to which the push button is attached, protrusions 19 and 20 are made to protrude obliquely upward and downward inwardly through thin hinge parts 18 and 18, and the tip of the upper protrusion 19 is attached to the top of the upper end of the inner circumferential wall. In the wall portion, the lower projecting pieces 20 are loosely inserted into the first through holes 12, and the tips of the projecting pieces are brought into contact with the upper surface of the shoulder. When the left and right push buttons 17, 17 are pushed in at the same time, the upper and lower projecting pieces 19, 20 swing relative to each other about the thin hinge portion and stand up vertically, and the cap 6 is then pushed upward. Therefore, the first and second engaging protrusions 5 and 9 are provided so that they can be disengaged from each other.

The aforementioned container body, cap, and operating member are each molded from a synthetic resin material.

``Effect of the invention'' The present invention has the above-mentioned structure, and by simultaneously pressing the push buttons 17, 17 protruding from the left and right sides of the outer circumferential wall of the cap, the engagement between the cap and the mouth and neck of the container body is released. Since the cap can be fitted by pressing the cap against the mouth and neck, the cap can be opened and closed extremely easily and quickly.
9 and 20 are designed to push up the cap by vertical displacement, so the force applied to the push button is doubled by the toggle mechanism and pushes up the cap, making it convenient to open the cap with less force. The tip of the upper protruding piece is loosely inserted into the top wall portion of the upper end of the inner peripheral wall, and the lower protruding piece is loosely inserted into the first through hole so that its tips abut the upper surface of the shoulder, so that when the push button is pushed in, it will not touch the top wall. The lid can be opened easily by vertically verticalizing both the upper and lower protruding pieces without shifting the positions of the two equal protruding pieces. Furthermore, elastic ring 1
Projecting pieces 19 and 20 are made to protrude obliquely upward and downward inwardly from the upper and lower edges of the button 6 through the bent parts 18 and 18, and the push button 1 is attached to the outer surface of the elastic ring portion from which the protruding pieces are made to protrude.
