Definitions
- the invention relates to a plastic closure with a snap hinge with the features in the preamble of claim 1.
- Plastic snap hinges can be roughly classified into two types, namely those in which the snap action is achieved by a tension element or those in which this is done by a resilient bending element.
- the present invention relates to a plastic snap hinge of the second type according to the preamble of the independent claim.
- US-A-4'414'705 (Ostrowsky) has a closure with a hinge with snap action.
- the hinge axis is also far outside the actual lock.
- the snap effect is created by a toggle-like bending element in connection with the hinge.
- the snap opening angle is large, but is bought with an oversized arm on the lower part of the closure for articulating the bending element.
- resilient bending elements which have a U-shaped or L-shaped shape.
- the dimensioning of the bending elements is essentially dependent on the spring travel and the spring force that are desired.
- the known bending elements could not be used.
- the leg extending into the cover surface of the cap cannot be made long enough because it would otherwise be in the sealing area of the pouring opening reaches in.
- U-shaped bending element this cannot be made large enough because the small cap height does not offer enough space to accommodate the bending element.
- the present invention has for its object to provide a plastic closure with a snap hinge, which enables a good snap action even when using a relatively flat cover with a minimal size.
- FIGS. 1-5 show a plastic closure which is suitable for a plastic container 30 which only has a small outlet opening 31.
- Such containers are used in particular for cosmetics that are applied directly to the skin, such as sun creams or body lotions. This means that the cap 2 of the closure can be pivoted open at least approximately 180 ° with respect to its closed position.
- the closure consists of a lower part 1 and a cap 2 which are pivotally connected to one another via two film hinges 3 arranged on a straight line, the film hinges being arranged within the cross section of the lower part or the upper part.
- the film hinges can also be located directly on the circumference of the lower or upper part, as can be seen in FIGS. 6 and 7.
- a bending element 4 which generates the spring force required for the snap action.
- the lower part 1 consists only of an annular, vertical side wall 10, which has only a tapered collar 11. Even in the closed state, a gap 12 remains between the cap 2 and the lower part 1. This is necessary in order to be able to inject the closure in the closed state.
- the collar 11 of the lower part 1 is pulled down, so as to form a recessed grip 13, which allows the cap 2 to be pushed upwards with the thumb up to the unstable equilibrium position, whereupon the cap in the fully open position, as shown in Figure 4, snaps.
- the sealing of the cap 2 with the pouring opening 31 of the container 30 takes place by means of a sealing pin 21 molded onto the underside of the cover surface 20.
- This can be provided with one or more circular sealing rings 22 to increase the sealing and in particular the locking force.
- the cover surface 20 is shaped concavely from above for optical reasons, but also to increase the rigidity.
- a plurality of support cams 23 can be attached to the underside of the cover surface 20. These are in assembled State 1 of the closure and closed position of the cap 2 on the container 30.
- the bending element 4 can also be removed from the mold when the closure is closed.
- cross section it has the shape of a U and an adjoining L. which is upside down.
- the recess 40 of the U-shaped part runs exactly in the direction of extension of the tool.
- the bending element 4 is connected to the cap 2 or the lower part 1 via two joints 41 and 42.
- the hinge 41 which forms the connection between the side wall 10 and the bending element 4, lies approximately at the level of the upper edge of the container 30 on which the closure is mounted.
- the hinge 42 connects the cap 2 to the bending element 4.
- the two joints 41 and 42 are each equidistant from the fixed film hinge 3.
- the minimum distance between the two joints 41 and 42 is a ⁇ ⁇ 2 if the distance from each joint 41, 42 to the film hinge 3 is equal to a.
- the maximum distance between the two joints 41 and 41 is reached and is exactly 2 a. This is the case when both joints 41, 42 are vertically one above the other.
- FIGS. 6 and 7 show a further embodiment of the invention using a second closure.
- This closure has essentially the same features as the closure previously described and shown in FIGS. 1 to 5.
- This closure is suitable for a container 30 '(only dotted) with a further container neck 32.
- the lower part 1 must be designed so that it can grip around the container neck 32.
- the side wall 10 'of the lower part 1 which bears against the container 30' is provided with a cover surface 14 which has a vertically downwardly directed annular wall 15 which sealingly engages around the container neck 32 of the container 30 '.
- a spout 16 is formed in the top surface 14 of the lower part 1 within the area delimited by the annular wall 15.
