JPS5845239Y2 - container safety cap - Google Patents

Description

[Detailed description of the invention] Originally, a cap with an internal engaging part was removably fitted via a spring body to a container opening that had an external engaging part and a discharge port at the upper end. , the safety of the container is such that by pushing the cap down against the spring body, disengaging the engagement part, and rotating the cap, the cap comes off from the container opening, allowing the medicinal solution and other contents inside the container to be taken out. Caps are well known in the art.

By the way, in this device, the engagement and retention of the cap and the container mouth depended solely on the spring body interposed between the cap and the container mouth.

The present invention relies only on the spring body for the engagement force in the retaining part during normal times, and when opening the cap, the deformation restoring force of the cap itself is used in addition to the spring body to provide the force to resist the pressing down of the cap. I made them add it.

That is, in order to push down, a force is required to counter the deformation of the outer cap, so a stronger pushing down force is required than in the past, thereby further increasing safety.

The present invention will be explained with reference to the example shown in the drawings, in which a container opening having a detachable part on the outside and a discharge port at the upper end and a cap with a detachable part on the inside are removably fitted together via a spring body. In the conventional well-known container safety cap, the container opening 1 (
In the figure, it is formed separately from the container body.

) is provided with retaining recesses 2 at multiple locations on the outer surface of its body, and following the recesses is provided a guide tongue portion 3 that slopes downwardly and outwardly, so that the outer surface 4 between each recess is approximately Approximately flat in shape, the cap 5 is made of highly elastic cylindrical plastic, and has an engaging protrusion 6 protruding from the inner side of the lower edge at a location opposite to the recessed part 2. It is something.

4 and 6 are longitudinal sectional front views of the container opening and the cap according to the present invention, and FIG. , the cap 5 is in a closed state where it is pulled up by the spring body 7.

Now, when the cap 5 is pushed down against the biasing force of the guide member to open the cap, the engagement protrusion 6 on the inner side of the lower edge of the cap is disengaged from the engagement recess 2, and the guide tongue piece continues below. It is moved downwardly and outwardly over section 3, at which point the walls of the cap are forced outwardly.

Then, the peripheral wall between the retaining protrusions of the cap is crushed and deformed from the circular shape in FIG. 5 to a nearly triangular shape toward the flat surface of the outer surface of the container mouth.

The cap will not be pushed down unless the pushing down force is increased before this deformation occurs.

In order to push down the cap in this way, in addition to the force that opposes the spring body interposed between the cap and the container mouth, a force that opposes the deformation of the cap itself is required, which is more difficult for children than before. Furthermore, it becomes difficult to open, further increasing safety.

Note that the lower part of the cap should have an appropriate thickness taking into consideration the state of deformation.

Further, it is preferable to display marks 8 and 9 on the cap and the container opening to indicate the position of the locking part.

A plate-like part 10 is connected to the root of the spring body 7, and this plate-like part is supported by an annular convex part 11 provided inside the cap.

The opening of the container opening is held down by the center of the spring body.

Reference numeral 12 indicates the container body.
