Abstract

A unitary snap hinge made of plastic with two hinge parts which are connected with each other by means of a main joint. A flexible connecting piece is connected with the hinge parts by means of secondary joints, whereby the secondary joints have a distance from the main joint transverse to the joint axis and that the joints are designed as film joints. The hinge parts have the tendency to snap into the one or other end position from a position of an unsteady balance within their own pivot range. The snap hinge is a separate structural element. The one hinge part supports a locking element for a removal opening, the other hinge part supports at least one adapter piece with arresting elements. Thereby, the snap hinge can be mounted on a container or on the locking piece of the same. A snap hinge or other hinge made of plastic and which is part of a lock may have tearable parts on its foldable hinge part which during the first time closing of the lock are fixedly connected with the lower part thereof and are torn off during the first time opening.

Claims

1. Container (210) for longitudinally extending diagnostic test carriers (212) comprising:

a longitudinally extending container body (216) for receiving the test carrier (212), whose inner space length is larger than the length of the test carrier (212) with a removal end (236) at which the removal opening (234) is disposed and with a container bottom (220) at the end facing away from the removal end (236) of the container body (216), and

a locking means (218) for locking the container body (216) in a moisture proof manner, wherein

the container body (216) and the locking means (218) are injection molded parts,

the container body (216) has a flattened cross section in a plane transverse to its longitudinal direction deviating from the circular shape,

a locking element (252) having a protrusion is mounted on a locking shank (242) which is pivotably mounted at the removal end (236) of said container body (216) by means of a hinge (244),

the locking shank carries the protruding locking element (252) having a sealing face (254) adapted to seal with a sealing edge (256) of the removal opening (234),

the cross section of said removal opening (234) is considerably smaller than the cross section of the container body (216),

the container bottom (220) encompasses a bottom element (222) being separate from the remainder of the container body (216) and moisture proof connected therewith, and

the container body (216) encompasses a chamber for receiving a drying substance.

2. Container in accordance with claim 1, characterized in that said bottom element (222) encompasses a chamber (230) with a drying substance which is closed toward the inside of said container with an element (232) which regulates the moisture supply.

3. Container in accordance with claim 2, characterized in that said container body (216) including said bottom element (222) consists of polyethylene or polyethylene or polypropylene having a wall thickness of at least 1 mm.

4. Container in accordance with claim 3, characterized in that said locking element (252) with its associated sealing face (254) is designed as a circular protrusion protruding vertically from said locking shank (242) being elastically compressible toward its center, whereby said sealing face (254) has a circular cross section.

5. Container in accordance with claim 4, characterized in that said locking shank (242) is a separate part from container body (216) and is connected therewith by means of a clamping and/or locking connection (246,248) which encompasses said locking shank (242), a mounting shank (240), and a plastic film hinge (244) with a snap spring (260) connecting said two shanks.

6. Container in accordance with claim 5, characterized in that said locking shank (242) is provided with a protrusion (246) being so disposed that it engagingly abuts against an associated abutment (268) of said container body (216) during the closing of the container, so that a noticeable resistance must be overcome for the continuation of the closing movement.

7. Container in accordance with claim 1, characterized in that said locking means (218) comprises a snap hinge wherein the snap hinge is separate from the container body.

8. Container in accordance with claim 7, wherein the snap hinge comprises two hingedly connected parts, said parts being the locking shank (242) and a mounting shank (240).

9. Container in accordance with claim 8, further comprising a film hinge hingedly connecting the locking shank and the mounting shank.

10. Container in accordance with claim 9, wherein the mounting shank (240) has a first protrusion (246) which couples to a corresponding second protrusion (248) mounted on the container body to secure the mounting shank (240) to the container body.

11. Container in accordance with claim 10, wherein the locking shank comprises a locking element (252) mounted thereon, the outer portion of which forms a sealing face (254) which sealingly engages on a sealing edge (256) of the removal opening (234) in the container body.

12. Container in accordance with claim 8, further comprising a safety protrusion (264) mounted on the locking shank (242), so dimensioned that its tip (265) abuts on an outer side of shoulder (266) of the removal opening (234) thereby requiring additional pressure to move the locking shank past a first position to seal the container body wherein in the first position a clear indication is provided that the package has not yet been closed properly.

13. Container in accordance with claim 9, further comprising a snap spring (260) located between the mounting shank and the locking shank and composed of plastic, the snap spring having a first and second spring part affixed by a spring film hinge therebetween wherein the axis of the spring film hinge and film hinge (244) are spatially offset in such a manner that a snap effect is obtained.
