Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The subject invention relates to a container-lid assembly according to the preamble of claim 1.

[0002]

BACKGROUND OF THE INVENTION Such a container-lid assembly is known from US Pat. No. 4,535,903. Such containers can be used, for example, in packaged products which should preferably be kept out of the hand of children. Examples of these are
Chemicals that affect health, such as drugs. When designing a child-proof closure for a medicinal package, it should be taken into account that it is necessary for geriatric patients to be able to open the package. This means that even if they show a certain group of children how to open the container, they cannot reproduce this behavior, while slightly impaired patients can actually do it. It means that the actual packaging closure should be designed.

US Pat. No. 4,535,903 describes a lid with a tongue that can be moved outwardly from around the lid. Otherwise, the perimeter of the lid is flush with the top of the container, so that when the tongue is in its retracted position, it is not possible to grip the lid tightly to secure it. It cannot be opened. Moving the tongue outward and causing a portion of it to protrude from the lid creates a mating surface for grasping the lid and opening it.

This is the first step towards closing a container that a child cannot handle, but once the child finds it possible to move its tongue to open its lid, the child is relatively It was shown that the behavior can be easily repeated.

Therefore, it is an object of the present invention to make it nearly impossible for a child to open, while leaving the lid relatively easy to open for others such as geriatric patients. It is to provide a further storage safety device.

[0006]

This object is achieved by using the container-lid assembly described above and providing the characterizing features of claim 1. When using the blocking means strategy for this tongue, the user must first act on these blocking means in order to move the tongue, but if so then the edges of this tongue are Must be able to move outwardly around the perimeter of this container-lid assembly. The blocking means, on the one hand, may have an inward movement of the tongue only afterwards, or the movement returns the blocking means to its original position, resulting in a movement of the tongue back. Finally, it can be realized by automatically blocking this tongue. On the other hand, it is also possible to design the blocking means such that it is free to move back and forth in a position in which it can be moved, but it does not automatically return to its blocking position. This last aspect is important when elderly patients use the container-lid assembly in places where children are unlikely to be present. In such cases, the "unsafe" position of the tongue is not important. However, if there are children, the first aspect is essentially preferred.

The blocking means for the tongue may include any means known in the art. On the one hand, to facilitate the operation of both the blocking means and the tongue, and on the other hand to make it as impossible as possible for the child to understand how to open the lid and move the tongue on the other Thus, according to a preferred embodiment of the present invention, the blocking means is provided with operating means for the tongue. This means that the blocking means must first be manipulated, and as a result the tongue is free to move, and the blocking means thereafter act to manipulate the tongue. You can

According to a preferred embodiment, in order to prevent a child from inserting a sharp object such as a knife between the lid and the container to open the lid from the container, a rim ( Between these, the lid is received). In contrast to the container-lid assembly according to U.S. Pat. No. 4,535,903, it is not possible to insert something like a knife or screwdriver that provides the force to open the lid between the lid and the container.

According to a preferred aspect of the invention, the blocking means comprises a cam connected to the tongue, wherein the cam and tongue can slide back and forth in the lid. . The cam is part of a rotating annulus provided on the top of the lid and can mate with a curved disc provided with a gripping member. Through rotation of the annulus, the cam can be located in front of the free part of the curved board, so that the tongue can freely move back and forth with the cam. However, when the curved disc is in another position, the movement of the cam or the movement of the tongue is blocked. In such an embodiment, on the one hand, the container can be stored in an unsafe position, i.e. in a position where the curved plate allows free movement of the cam, or in a safe position.
That is, the container can be stored with the curved plate in some other position blocking the movement of the cam.

According to another aspect, the blocking means is provided with a rotatable blocking board, wherein one tip of it is provided with operating means and on the other side, on the one hand, Means are provided to rotatably engage the tongue and, on the other hand, a circular, non-curved portion is received within a slit provided in the lid. The slit is realized so that the movement of the curved part within the slit can be realized only at a predetermined position. In this way, it is possible to manipulate the tongue through the blocking disc only when the blocking disc is in a predetermined position. In all other positions the movement of the disc and thus of the tongue is hindered by the juncture of the boundary of the curved part and the slit.

For the purpose of improving the ease of use of the container-lid assembly according to the preferred embodiment, indicia for orienting the rotary ring or blocking disc relative to the lid are provided on the rotary ring, blocking disc or the lid. On at least one of the upper surfaces of the.

The perimeter of the lid, such as the protruding rim as described above, and the portion to which the hinges are connected can be molded integrally with the container, but in a preferred embodiment, the container is Provided below the blocking / manipulating means is a further lid surface linked to the blocking means, which cooperates with the corresponding means of
Thus, there is a regular lid that cooperates with the perimeter edge that may be connected to or snapped to various types of containers in some other manner known in the art. A lid assembly that is open can be realized.

The invention will be further clarified by reference to the preferred embodiments of the invention shown in the drawings. However, it should be understood that these are merely examples.

DESCRIPTION OF THE PREFERRED EMBODIMENT In FIG. 1, this container-lid assembly is generally designated by 1. It includes a container designated by the reference numeral 2 and which is provided with an opening 30 and a lid, generally designated 3. As is clear from FIG.
The lid 3 is provided with a peripheral edge 31 to which a lid portion 32 is connected. It is clear from FIG. 3 that this lid part has an upper surface 4 and a lower surface 5. Between them there is a limited space for receiving the tongue 6, which can be moved in and out of this lid, as will be apparent from a comparison of FIGS. 3 and 4. A cam 7 is provided on the tongue 6. Between the upper surface 4 and the lower surface 5 is provided a rotary ring 8 which is provided with slits 9 as can be seen from Figure 3a. In Figure 3,
The cam 7 having the protruding portion is just the slit 9 described above.
A slit 9 is shown on the left side of this figure so that it can be moved under. Interlocking ears 10 on the rotary ring 8
Is equipped with. For the purpose of realizing the positioning of the ring 8 as shown in FIG. 4, marks 11 and 12 are realized respectively on the ring and on the upper surface of the lid, as shown in FIG. Figure 3
As can be seen, in the corresponding receiving section 14 of this container, stop (snapping
g)) Providing the sealing edge 13 on the lid 32. The container is further provided with a peripheral groove 15 in which the protruding portion 16 of its peripheral edge 31 can be accommodated. Figure 1
As can be seen, the front side 19 of this lid and the front side 20 of this container are in the same plane.

The embodiments shown in FIGS. 1 and 4 perform the following functions.

In the manufacture of containers with different sizes, different size containers are realized in which the neck of the opening 30 is always the same. As a result, the same peripheral edge 31 can always be fastened to different containers, where the protruding part 16 engages the peripheral groove of this container.
The lid is connected by a hinge 18 to the peripheral edge. When this lid is held in the closed position (which is realized by the cooperation of the parts 13 and 14), when the tongue 6 moves inwards, as seen in FIG. A coplanar transition between 20 and 20 occurs. This makes it impossible for the (young) user to remove the lid from the container. The interlocking force between this lid portion 32 and the container is too great. If this lid needs to be opened, the tongue 6 has to be moved outwards to the position shown in FIG. When in this position, the bottom of the tongue 6 can be pushed so that the lid remains open. The tongue 6 can only be moved outwards by moving it from the position according to FIGS. 1 and 3 to the left of the cam 7. Such a leftward movement of the cam 7
Except when the slit 9 is moved to the left, that is, the mark 11
It is restricted by the rotary ring 8 in all positions, except when they are moved to a point in front of each other.
The user can select whether or not to re-lock the lid by removing the item from the container, moving the tongue inward, and then rotating the rotary ring.

5-7 illustrate a second embodiment of the container-lid assembly according to the present invention. This most preferred embodiment includes a container, but in contrast to the first embodiment shown above,
The container and the lid 32 are integrally formed. Such an embodiment is of interest if the same container needs to be mass-produced and can be realized, for example by injection moulding. A film hinge 48 connects the lid 32 and its container.

The lid 32 is provided with an internal slit 39 for accommodating the tongue 52 which is provided with an opening 35. The pin-shaped part 45 provided on the blocking board 38 can be inserted into the opening 37 of the tongue 52. For the purpose of clearly showing the shape of the pin-shaped portion 45, this is shown separately in dotted lines between the blocking board 38 and the lid 32 in FIG. The flat portion of this pin is indicated by reference numeral 46. The pin 45 can extend through both the left and right sides of the opening 35, but only transitions from its left side to right side or right side to left side in the position where the flat portion 46 of the pin 45 faces the protrusion 36. It is clear from FIG. 7 that this can be done. The pin 45 is received in the opening 35 in a rotatable manner. Indicia 41 and 42 are provided for the purpose of providing instructions for the exact location of the blocking board 38.

Blocking board 38, as described above.
Can only be moved if the flat part 46 on the pin 45 faces the protrusion 36. In that position, the tongue can move out of the perimeter of the container, as shown in Figure 6a. When in that position, it is possible to catch the lid and remove it from the container, as shown in Figure 6b. The projecting opposite edges 50 of the container prevent the approach of knives, screwdrivers, etc. that force the lid to open.

FIGS. 8-10 show a third embodiment of the present invention. In this embodiment as well, the container 2 is provided with a lid, here indicated by 23. The lid also has a peripheral edge and a regular lid portion. This peripheral edge is realized in the same way as in the embodiment described above, but this lid part is designated by the reference numeral 33. This lid portion 33 is connected to its peripheral edge 31 by a hinge 28. The lid portion 33 is provided with an upper surface 24 and a lower surface 25, as in the previous embodiment, with the tongue 22 provided therebetween. The opening 27 is realized in this upper surface. This tongue extends with a curved portion 29 extending through the opening 27. A projecting edge 26 is provided on the upper surface of the lid for the purpose of positioning the curved portion in place.

The embodiments described above perform the following functions. Starting from the closed position shown in FIG. 9, the user needs to exert a force through the opening 27 and onto the curved portion 29. Thereby, the tongue 22 moves outwardly to provide a gripping point for this lid part, through which it can be removed from its container. In this manner, releasing this curved portion 29 will cause it to always bounce back and return to the position shown in FIG. 9, thus ensuring automatic safety after the lid is closed. To be done.

Although the present invention has been described above with reference to three preferred embodiments, it should be understood that numerous changes can be made. It will be apparent to those skilled in the art that the lips can be blocked from catching its lid in a number of ways. All of the above improvements are considered to be within the scope of the claims set forth herein.
