Cap (1) has an inner skirt (3) with H (10) is a screw thread (4) which co-operates with a screw threaded neck (11) of the container, and a sprung outer skirt (5) which surrounds inner skirt (3). Container (10) has a locking ring (15) with two slots (16,17); cap (1) has two lugs (7,8) which engage in slots (16,17) when the cap (1) is fully screwed on to the container (10) and the outer skirt is in a first, rest position thereby preventing the cap from being unscrewed. Outer skirt (5) can be moved to a second, stressed position in which lugs (7,8) disengage from slots (16,17) to allow partial unscrewing until lugs (7,8) are aligned with the opposite slot (17,16). The resilient component of the outer skirt (5) urges it back to the first, rest position and lugs (7,8) pass through slots (16,17) due to axial movement of inner skirt (3) during the partial unscrewing. Thereafter cap (1) can be fully unscrewed from the container.

Description

The The present invention relates to a container and a closure lid and in particular a container, which has a child-resistant closure lid.

Childproof container lid for disinfectant containers and like that are common of the well-known type for squeezing and turning, in which the lid has an enclosure which is located at two diametrically opposite Points must be squeezed to disengage attacks that on the mount and the container are formed to allow rotation of the lid for removal. This type of lid can be made simple and inexpensive, because they can be molded as one-piece construction.

Childproof Cover for Pharmaceuticals often use an arrangement in which a lid is pressed down must to allow removal. These arrangements are generally quite complicated and therefore expensive to produce. Lids that can be operated by she pushes down, but instead of being squeezed, older people do preferred, find the squeezing unwieldy.

Lots Cover for pressing and turning use an inner lid that closes the container, and an outer lid, the depressed must be in order to engage with the inner lid before The covers are then unscrewed together. However, the use does of two lids in the production of an assembly step necessary and enlarged in the Generally the complexity the construction.

The document US 3,830,391 describes a one-piece closure and a container in which the closure has an inner and an outer wall which are connected by an elastic bridge. The outer wall has locking tabs which engage stop members on the container. In order for the tabs to pass the abutment elements, the outer wall must be pushed down and then held down, while the closure is unscrewed to the point where the inner wall has moved sufficiently in the axial direction to allow the tabs to pass over the abutment elements fast, when the outer wall is relieved.

The The present invention seeks to provide a child resistant container and To provide closure cap which can be actuated by press down on the lid, but still of simple and inexpensive construction.

Accordingly becomes a container and a cap for it provided, with the container having a screw-threaded neck, wherein the Cover a face plate for closing the neck, one of the Face plate drooping having inner skirt and a screw thread for cooperation having the neck thread, and an outer skirt, which the surrounds the inner skirt and is elastically connected thereto, wherein one of the container and the closure a locking ring with at least one recess having the other at least one nose, which engages in a recess when the lid is screwed all the way onto the container is and the outer facing is in a first resting position, which prevents that the lid is unscrewed, the outer casing in a second Position is movable, in which claims the elastic connection is and in which the nose is disengaged from the depression, to allow the closure to be partially unscrewed, until the nose is aligned with the recess, characterized that the locking ring is adapted to a movement of the outer skirt back in first position during to prevent partial unscrewing, so if the nose aligned with the recess, the elastic connection the outer casing back pushes in the first position and the nose due to the axial movement of the inner skirt during the partially unscrewing passes through the depression, whereupon the lid is completely off the container can be unscrewed.

Further preferred embodiments The present invention is disclosed in the dependent claims.

The elastic connection may comprise a bridge part, which itself between the inner and outer facing extends. By making sure that the bridge connecting the bezels to the closed front end of the lid, can the bridge form a part of the front plate, and the movement between the Mounts include a simple bending of the bridge.

A A plurality of depressions and noses may be provided; at a preferred embodiment the locking ring has two recesses, and there are two lugs present, both diametrically opposed to each other substantially are. This arrangement is similar to both during use Side of the lid applied stresses. The number of depressions and noses does not have to be the same.

In the first position can be the outer border to the inner skirt at its point of connection with the face plate axially offset, whereby the bridge part is inclined. By doing in the first rest position, an inclined bridge part this one has an elevated Area to press on can. This allows using the palm on the Cover too. to press, which makes it easier to apply the required pressure.

The elasticity of the bridge part can be provided by the material of the part itself. To the For example, the part may be formed of an elastomeric material, like polypropylene. The bridge part needs not be formed from the same material as the rest of the lid, although this may be the case for ease of manufacture. The closure cap can therefore be a one-piece construction.

The Wells can longer be as the noses, creating a smooth uninterrupted unscrewing allows becomes more detailed below is described.

The The present invention will now be described in more detail by way of examples with reference to the accompanying drawings, in which:

1 is a perspective view of a closure lid;

2 a perspective view of a container for use in conjunction with the lid 1 is;

3 a perspective sectional view through the container 2 is that with the lid off 1 is shown completely screwed;

the 4A to 4D schematic vertical sections through the in 3 shown container and closure lid, illustrating the operation of the lid; and

5 a schematic side view of a container according to an alternative embodiment.

First, referring to 1 , there is a child resistant cap shown, which is generally with 1 is designated and a circular face plate 2 having. An inner surround 3 depends on the face plate 2 down and is with an internal screw thread 4 educated. An outer enclosure also depends on the faceplate 2 down, radially outward from the inner skirt 3 , and this creates a hollow space between the two borders 3 . 5 , At the open end of the outer border 5 there are two diametrically opposed noses 7 . 8th towards the inside of the lid. The outer skirt is through an annular bridge part 20 (in 3 most clearly shown) elastically connected to the face plate.

A container for use with the lid off 1 is in 2 represented and is generally with 10 designated. The container 10 has a cylindrical neck 11 on, with an open end and an external screw thread 12 for interaction with the screw thread 4 on the cap 1 is trained. The neck 11 is with the main body 13 of the container through a shoulder 14 connected. At the foot of the neck 11 in the area where he is with his shoulder 14 is connected, extends an annular locking ring 15 perpendicular to the main axis of the container 10 , The locking ring 15 is with two diametrically opposed elongated depressions 16 . 17 provided that the noses 7 . 8th the closure lid 1 correspond.

The interaction of the cap 1 and the container 10 is in 3 shown more clearly. When the cap 1 all the way to the container 10 is screwed, grab the nose 7 . 8th into the wells 16 . 17 one, which prevents the lid 1 is unscrewed.

The annular bridge part 20 is shown as a base 21 made of material compared to the inner one 3 and outer 5 Bezel is relatively thin, and a plurality of radially extending, spaced ribs 22 comprising, extending from the plate 2 to the outer border 5 extend. The local dilution increases the relative elasticity of the bridge part 20 and reduces stress during use. The bridge part 20 serves as a spring, for a resilient outer mount 5 to worry as described below.

Although through the ribs 22 provided knurling is undesirable from the viewpoint of the compliance of the outer casing spring, it provides gripping friction in order to allow the closure to be opened using the palm of the hand without the need for a squeezing force.

The operation of the cap 1 and the container 10 will now be with reference to the 4A to 4D described in more detail. In 4A is the cap shown screwed all the way to the container, as in 3 shown. The bridge part 20 is shown as tilted up, and the noses 7 . 8th are as in their respective wells 16 . 17 shown engaging. In this position, the cap can 1 because of the Engagement of the noses 7 . 8th into the wells 16 . 17 not be rotated in relation to the container.

Referring now to 4B , is the outer mount 5 moved to a second position in which the noses 7 . 8th from their depressions 16 . 17 have been disengaged and now below the height of the locking ring 15 are located. You will see that in this position the bridge part 20 has moved and is now in a stressed state.

If the noses 7 . 8th from the wells 16 . 17 are disengaged, the cap can 1 now partially unscrewed, as the noses 7 . 8th under the locking ring 15 can pass through. The bridge member is resiliently biased to the first position, but because of the engagement of the lugs 7 . 8th under the locking ring 15 unable to push up the outer skirt. While the cap 1 is unscrewed, begins the inner enclosure 3 to move axially due to the screw thread arrangement. The position of the outer border 5 is unchanged (because of the engagement of the lugs under the locking ring), however, the bridge part 20 further claimed as in 4C shown.

The partially unscrewing the cap 1 continues until the noses 7 . 8th have been rotated about 180 °, and they begin to work with the opposite depression 17 . 16 align. If the noses 7 . 8th completely with the wells 17 . 16 are aligned, expresses the elasticity of the bridge part 20 the outer border 5 back to the first position, and the noses 7 . 8th occur due to the axial movement of the inner skirt during the partial unscrewing through the recesses 17 . 16 therethrough. As soon as the noses 7 . 8th through the locking ring 15 passed through, the cap can 1 entirely from the container 10 be unscrewed.

It will be seen that when the pits 16 . 17 essentially the same size as the noses, the unscrewing process could not be uninterrupted. Because the pits 16 . 17 considerably longer than the noses 7 . 8th are (in this embodiment, about twice as long), the unscrewing can be uninterrupted; the additional length of the recesses makes it possible to rotate the closure lid while the noses 7 . 8th axially through the depressions 16 . 17 move. If the recesses were the same size as the noses, the unscrewing process would have to be done in several steps; the user would have to gently unscrew the closure to the point where the noses will snap all the way through the depressions, during which time no rotation would be possible.

If the lid on the container screwed back the noses snap back into the wells; the recesses prevent over tightening and serve as an end stop for Deckelanbringmaschinen.

at other embodiments (not shown), the locking ring is arranged on the closure lid, and the noses are on the container arranged. The principle behind the operation of such a closure is exactly the same as previously described.

at this embodiment the cap is injection molded as a single piece.

Of the container Can be made by extrusion blowing using materials such as HDPE or by Spitzstreckblasen using materials how PET are made. The cap can be made of HPPE, Polypropylene or other elastomeric material can be produced.

Referring now to 5 , there is a container 110 shown according to an alternative embodiment. The basic education and function of the container 110 is the same as the container 10 from the 1 to 4 , In this embodiment, the locking ring 115 between the wells 116 . 117 tilted slightly upwards. The tilt makes it easier to use a closure lid (not shown) during the time his noses are under the locking ring 115 go through, start screwing. Without inclination, turning the lid becomes more difficult as the inner and outer enclosures move relative to each other against the elasticity of the bridge member. The inclination of the ring 115 reduces the relative movement of the bezels.

In addition, the locking ring 115 adjacent to each of the wells 116 . 117 a stop 118 on. The attacks 118 have a sloping surface 119 which is inclined away from the direction of unscrewing, and a demolition surface 125 , which determines the beginning of the recess.

The function of the stops 118 is a double. First, the area increases 125 the local width of the locking ring 115 , which makes it more difficult to forcibly open the cap, bypassing the mechanism for pushing and turning. Second, the oblique surface causes 119 just before the noses engage the recesses, a change in the force required to screw the closure back onto the container; the noses will also enter the wells with a specific click sound. This informs the user that the Be container is completely closed.
