DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a closure device for containers, and in particular to a device for closing containers such as pills or other drug bottles having a cylindrical opening.

A closure device such as a threaded body of a container having a threaded opening in the neck at -a can be relatively easily removed by loosening the thread. However, this method cannot be used in cases where the container contains harmful drugs or dangerous chemicals, such as if a child were to unscrew the closure and touch the contents or put them in the mouth. There is a danger that this could lead to negative consequences. Therefore the container is safe,
Alternatively, sealing devices that can only be opened by authorized personnel are required, but these are generally complex and expensive.

According to one aspect of the invention, a closure device for a container having a cylindrical opening comprises first and second cylindrical closure members each having an end member and an attached skirt member, and a hinge and a hinge therefrom. means for directing a first relative axial movement between the first and second closure members having spaced apart detents, the detents having a spaced apart detent that directs the direction means for directing the first relative axial movement between the first and second closure members; A container closure device is provided that is adapted to remain in place until movement occurs.

The first cylindrical closure member has an aperture in its end member, in which the boss of the end member of the second cylindrical closure member is aligned, and the indicating means is adapted to be connected to the second cylindrical closure member by the hinge. 1 cylindrical closure member and includes a tab projecting beyond the boss.

It is assumed that the hinge is always biased in the open state.

The detent strikes a protrusion projecting into an aperture in the first cylindrical closure member on an adjacent portion thereof.

A protrusion is formed on the side surface of the tab of the indicating means opposite the boss of the second cylindrical closure member, and the protrusion and the boss engage with each other by relative axial movement so that the tip passes through the detent. It is designed to energize the parts.

The surface of the boss opposite the protrusion has an annular concave surface opposite the protrusion, the concave surface and the protrusion forming a mating cam surface that engages by said relative axial movement.

These cam surfaces are sloped, for example, so that the projections form a substantially figure-7 shape in the axial section of the device.

The projection can be adjacent to the hinge.

According to a second aspect of the invention, there is provided a method of assembling the aforementioned device.

According to a third aspect of the invention, a method of forming a container closure having a cylindrical opening comprises providing first and second cylindrical closure members each having an end member and a cylindrical skirt member. providing an indicating means permanently connected to the end member of the first cylindrical closure member, the indicating means being adapted to indicate, in use, whether the device has been operated;
moving the first and second cylindrical closure members in a direction opposite to the direction of movement; and combining the first and second cylindrical closure members with each other such that the second member is within the first member with their end members being close to each other. I'll separate it.

A method is provided in which the indicator means is maintained in such a manner that the indicating means is operable upon the use of the combined first and second closure members.

A container closing device that specifically implements the present invention will be described in detail below with reference to the drawings.

In FIGS. 1 to 8, the same or similar reference numerals are used for the same or similar parts. The closure device (100) is injection molded of plastic material and is intended for attachment to a cylindrical opening with external threads in a container (not shown) such as a round I or pharmaceutical bottle or the like. be.

The closure device (100) includes a first outer cylindrical closure member (10

05) and an attached skirt member (not shown). First and second cylindrical sealing members (102) and (1
03) are individually injection molded from plastic material and assembled together to form the enclosure W (100). A first driving means is provided between each skirt member for integrally driving the first and second cylindrical closing members (102) and (103) only in the direction in which the closing device (100) is mounted on the container opening. (
(not shown) is equipped. Further, between the end members (104) and (105), the first member (102) is provided with means (not shown) for acting to separate the first and second members (102) and (103). It is equipped with second drive means (not shown) capable of moving towards the second member (103) when the second member (103) is moved in the axial direction. The operation of the second driving means causes the first and second members (1
02) and (103) can move together in opposite directions to remove the closure device (100) from the container opening.

One end member, i.e. the first, outer cylindrical closure member (
The end member (104) of the first member (102)
) with respect to the second member (103), means (106) are permanently connected thereto for indicating whether or not the device (100) has been operated.

This indicator means (106) is formed in the end member (104) of the outer closure member (102) and is in the form of a tab (107) that controls the second boss (108) on the end member of the inner cylindrical closure member. and the first cylindrical sealing member (1
02) projecting across an opening (109) in the end member (104). The opening (109) is circular and the boss (108) is cylindrical with a diameter slightly smaller than the diameter of the opening (109) and is slidably fitted into said opening (109). The tab (107) is hinged (
It has a tip (110) forming a free end spaced from (111).

This free point (110) has a detent or projection (112) on the end member opposite the hinge (111).
), which is integrally molded with the end member (104) and the tab (107);
For example, as shown in FIGS. 6 and 8, it is constantly biased toward the "open" position.

During assembly of the first and second cylindrical closure members (102) and (103) to form the closure device (100), the tab (107) is attached to the detent (112) (assuming that it is used). is biased so that it is located below. The hinge (111) connects the tab (107) to the end member (104).
). The tip (110) is effectively locked to the underside of the detent (112), although the top is apparently an integral part of it. Dress here! (
100) is mounted over the opening of the pill bottle and is opened by moving the outer cylindrical closure member (102) axially towards the bottle over the inner cylindrical member (103) as previously described. If you do this, the boss (10
B) forces the tip (110) so that it passes the detent, so that the energy stored in the hinge causes the tab (107) to jump to the angular value l shown in FIGS. 6 and 8. do it like this.

If the user considers the tab to be damaged based on the usage instructions, remove the tab (

Furthermore, if a child or the like operates the device without permission, this operation will be easily made clear and the user will be informed that this is a rudimentary prank.

There is a hinge (
A protrusion (113) is formed adjacent to the protrusion (111).

This protrusion engages the boss (108) during relative axial movement between the inner and outer closure members. During such axial movement, the boss (108) moves along the protrusion (
113) on the sixth tab (107).
It is moved to the position shown in the figure or FIG. In the embodiments shown in FIGS. 5 and 6, the boss is annular and has a concave surface (114) that has a complementary shape to the surface of the protrusion (113).
