A container for loosely stored products including a) a container body containing a peripheral body wall having an inner peripheral body groove; b) a cover containing a cover skirt having an outwardly facing sealing portion with an apex that seals against the inner peripheral body groove when the cover is in a closed condition thereby forming a seal of a sealing line type; and c) a hinge connecting the container body and the cover. The apex of the cover skirt and the inner peripheral body groove provide the only seal between the cover and the container body and preferably the only locking element that holds the cover in the closed condition on the container body.
1. A container for loosely stored products comprising
a) a container body comprising a peripheral body wall having an inner peripheral body groove in an inner surface of the inner peripheral body wall;
and
b) a cover comprising a cover skirt having an outwardly facing sealing portion with an apex that seals into the inner peripheral body groove when the cover is in a closed condition thereby forming a seal which is a sealing line;
wherein the apex of the cover skirt and the inner peripheral body groove provide the only seal between the cover and the container body when the container is in the closed condition;
wherein the peripheral body groove defines a groove radius in a cross section of the peripheral body wall and the apex of the sealing portion defines an apex radius in a cross section of the cover skirt;
wherein the groove radius is greater than the apex radius, and
wherein the apex of the cover skirt and the inner peripheral body groove additionally provide a locking element that holds the cover in the closed condition on the container body,
wherein the locking element is the only locking element that holds the cover in a closed condition on the container body.
2. The container of claim 1 , wherein the cover further comprises an outer peripheral cover wall situated radially outside of the cover skirt and radially outside of the peripheral body wall.
3. The container of claim 2 , wherein the cover further comprises a top wall from which the cover skirt and the outer peripheral cover wall extend, wherein a vertical distance of the apex of the sealing portion of the cover wall from the top wall is smaller than a vertical extension of the outer peripheral cover wall.
4. The container of claim 1 , wherein the peripheral body wall has, when viewed from a top side, rounded surfaces.
5. The container of claim 1 , wherein the container body has a cylindrical shape.
6. The container of claim 1 , wherein the inner peripheral body groove has a depth of between 0.05 mm and 0.7 mm.
7. The container of claim 1 , wherein a skirt outer diameter (da) of the cover skirt at a position of the apex is greater than a peripheral body wall inner diameter (dg) of the container body at a position of the peripheral body groove.
8. The container of claim 7 , wherein the skirt outer diameter (da) and the peripheral body wall inner diameter (dg) satisfy the equation da=dg+x, where x is from 0.05 mm to 1.5 mm.
9. The container of claim 1 , further comprising a hinge connecting the container body and the cover, wherein the hinge allows a rotation of the cover relative to the container body about a rotation axis, and wherein a vertical position of the rotation axis is, in an upright position of the container, between the apex of the sealing portion and an upper end of the peripheral body wall.
10. The container of claim 9 , wherein the rotation axis of the hinge is situated radially outside of the container body.
11. The container of claim 1 , wherein the cover is detachably connected to the container body.
12. The container of claim 1 , wherein the cover skirt is a separate piece of the cover.
13. The container of claim 4 , wherein a shape of the rounded surface of the peripheral body wall is selected from the group consisting of oval and circular.
14. The container of claim 1 , wherein the container, when closed, holds a depression of more than 600 mbar without opening.
