Description

Two-part container closure with two rotatable flaps. The invention relates to a two-part container closure with two rotatable flaps whose Axes of rotation are arranged parallel to one another without being connected to one another be. What is new is that the lower flap is locked in the closed position the upper pendulum flap holds. The upper locking part hangs freely in vertical position and only touches the slip surface when the lower one is in the closed position Flap. - This ensures that at the beginning of the unloading the goods are the upper Lifts the flap and thereby the outlet of the goods can be regulated. After this the container is essentially empty, leaves the vertically hanging upper flap the small items to be conveyed are still out and are only activated by lifting the lower flap brought to a complete end, creating a double lock.

The drawing represents, for example, an embodiment of the subject matter of the invention represent. Fig. I shows a one-sided attached \ -erscliltiss, consisting of two locking parts, while Fig. 2 shows the plan of this.

The upper main closure part d. is rotatable with your upper end on Container attached un-I always stands by its weight after emptying perpendicular. It is to be kept so narrow that it is between the ventilator side cheeks commute, i.e. can hit the container 'liine. How far he cludes in is of its length in relation to the total opening and the angle of the sloping floor addicted. The length is determined by the unit size and the weight of the rest Contents with reference to its effect against the closure part. It is clear that the fully flowing out conveyed the upper closure part d. in the dotted position 4 'brings, but as the height of the goods in the container decreases, the same sinks until he has reached the vertical position. If in this position he would nuninelir 'the close the entire opening, then a complete leakage of the filling material would be excluded. But since the closure part is kept shorter, it can be in its vertical position Do not close the opening completely, but rather a correspondingly large one remains Gap through which even the lightest remainder of the product, without @i "resistance to find, can leak.

In parallel under this main (pre) closure part 4 is a second one lower (end) \ "closing part 2 rotatably mounted at 3 so that it is in the open Position (dotted 2 ') as @ :: uts @ hl: ahn @ extension <borrows. So that he is in this Position is also considered to be an extension of the slide if it is above its pivot point in addition, an extension that acts as a stop against the sloping floor. As from the plan (Fig. 2) can be seen, this T @ is closing part 2 with side walls 6, which overlap over the sides of the vessel. In the closed position (Fig. r) the end closure part 2 is expediently loaded by a weight 8 Hook 9 held. As a result, the main closure part is held at the same time by the end closure against a strip attached to the main closure (or Angle) and so the latter, according to the height of this bar (or angle), more or less pushes in between the vessel walls on the sloping floor. In this way, the vertical position of the main closure part between this and the sloping bottom gap formed can be reduced to zero. The way of working is now the following: j; the main closure part 4., which is still in the Containers located amount accordingly, from the dotted position 4 'back until he arrived in a vertical position. Flows through the remaining gap the load completely. Then the lower one, which has been used as a slide until now, becomes Closure part 2 (by hand or automatically) lifted, i.e. folded up. Here the same lies against the bar 7 of the main closure part q., this the bar height accordingly pushing back until the lower locking part through the impacting Hook 9 is held.

The container is now ready for new loads. Everything seeping through the main closure part during loading and transport Load flows into the formed by the bar 7 between the two closure parts Storage space where it is appropriate to its angle of approach. So it can Nothing is lost even from the finest cargo, even if the main closure part d. no matter how leaky it is.

By depressing the hook 9 or lifting its weight 8, the lower closure part 2 is left free and falls into the slip position, which in turn the main seal is free and also opened by the outflowing material will.

The subject of the invention has the advantage that an operationally safe Work is guaranteed. Pre- and end-closure organs can be designed in the most coarse form, without sacrificing the accuracy of the closure in any way, and impaired wear resulting from the use of the locking devices reduces the accuracy the working of the individual parts does not.
