Friction clamped tabs as the side walls of the Cover parts are formed, the only by this Friction are intended to keep the lid in its closed position. The effect achieved here is not sufficient, since the coefficient of friction is too low to ensure a secure closure. Next to it is in U.S. Patent 2,423,756 a Slotted tab disclosed with a securing lug. The disadvantage here is that the locking pin must be made of stiff material so that this does not bend when the lid is closed and when the wrapped eggs are touched. Another problem that arises here is the length of the pin that is used when the container is closed comes into contact with the eggs. It is also possible to loosen the locking pins if during the closing process or stapein misalignment occurs between the pins and the slots.

a side wall 26 passes over, which forms the free end of the lid flap. The cover flap 16 consists in in the same way from a side wall 28, a middle part 30 and a side wall 32. The walls and middle parts are arranged in relation to one another in such a way that each of the lid flaps has an approximately U-shaped cross-section, as can be seen in FIG connected to the lid flap 14 and has a pair of tongues 38 and 40 at the free end and an opening 42 on. A pin 44 extends from the top flap pe 16 through this opening 42 when the Einurbehäiter is closed is. This pin 44 is located in a recess 46 in the central part 30 for receiving the tab 34 is provided. Another deepening 48 in the cover flap 16 allows a finger to be inserted into the gap between the tab 34 and the Lid flap 16 for the purpose of opening the lock * Xn In the closed position shown in Fig. 2, the lid flaps 14 and 16 are side by side with the sides » walls 26 and 32, whereby dl® Ksat® »50 and support 22 of the side walls on a central support 54 " The corresponding design of the Aufsiahinesa for the eggs and the support and thus de »Boden Ig can take place in a known manner, for example as it is in American patents 3 19! 344, S 3 © S 6O6 or 2,446,264 is disclosed.

This return force of the line of weakness 36 promotes the securing of the tab 34 by being pressed down over the pin 30 which enters the opening 42.

Tongues 38 and 40 are arranged on the flap 3 **, the design of which depressions 56 and 58 are matched as extensions of the Y3 £ "bleeding 46 in order to achieve an additional protection of the flap. As shown in FIGS As can be seen, the recess 46 in the middle part 30 of the cover flap 16 is essentially adapted to the shape of the Lasca © 34 and consists of a bearing surface 47 «where the plane lies below the middle part 30, somewhat deeper than the thickness of the flap 34 Bio jygag © ^ra d ^8ä between the ends of the recess expansions 56 and 58 is slightly smaller than the length ^C3 I) ^ß B% -i ± BGh®m. the ends of the tongues 38 and 4θ, so that the EnUQ represents Tab 34 has been glued into the corresponding parts of the - £ '-i3Mg (siöSie Fig * 5) © _?

and 16 are pushed together in the direction of arrows Aj B in Fig. 2, the sides 64 and 66 of the tongues are supported on the corresponding side walls 68 and 70 of the tongue receptacles 56 and 58 and thereby hold the free end of the tongue in place, thus the tab 34 can return to its original position when the cover flaps are relieved again. The flap tends to lift relative to the pin 44 as a result of the arching that occurs when it is compressed, and even if this comes free from the pin 44, the flap moves back into its closed position over the pin, since the free end of the same is held in its position and stretches the flap again when relieving the load on the lid flaps. If a longitudinal displacement of the lid flaps occurs in a mutual direction according to arrows C, D in Fig. 1, the edge 76 of the tab rests against the side wall 78 of the recess and counteracts such a relative movement between the lid flaps. The same occurs when a longitudinal loading of the cover flaps opposite to the arrows C, D occurs, the side wall 72 resting against the side wall 74.

The dimensions between the opening 42, the pin 44, the side walls 80 and 82 of the tab 34 and the recess s walls 60 and 62 of the recess 46 are such that any tension exerted on the tab 3k and causing the lid flaps to open is due to the Side walls and 82 ider tongues 38 and kO are received, which are supported on the side walls 60 and 62, as well as by the wall of the opening 42, which rests on the pin 44. Depending on the tolerances, the wall of the opening 42 can be below

Deform the load slightly before the load is applied Tongues 38 and 40 acts or vice versa. It is to be noted that with each opening tendency for the lid flaps these are pivoted away from each other and the tab 34 and the central part 30 have the tendency to evade in opposite directions, the recess walls 60 and 62, the tab 34 under tension keep. Therefore, the egg container according to the invention can also be handled with its top down, the weight of the eggs exerting pressure on the lid flaps 14 and 16 with a tendency to open them, at the same time the tab 34 is under tension is set, whereby this is in their secured position is held.

An additional, but not necessary, possibility of holding the tab 3k in its secured position is to generally press the tab under tension. This can be achieved by curving the walls 26 and 32 in opposite directions, with the cover flaps taking up the position shown in FIG is used.

In Fig. 6 the closure of the egg container is shown in a modified form. For the similar parts already present in FIGS. 1 to 5, the same reference numbers have been used with the addition of ⁿ a ⁿ . An undercut 102 is provided in the pin 44a and the

009826/0161

Opening 42a is in the flap Jka. arranged so that the part 104 of the tab enters the undercut 102 in the region of the opening 42a. The undercut provides an additional advantageous measure against unintentional loosening of the tab due to pressure, piercing or other tab influencing in the opening direction forces. Alternatively the undercut is a bias voltage 44a possible by means of a surface curvature on the side of the pin, from the bottom of the recess 46 Λ

to the tip of the pin 44a in one of the free end the direction facing away from the lid flap or by tilting the pin accordingly

Another modification of the closure elements according to FIG. 1 is shown in FIG. Here they are already Reference numbers used are provided with an additional "b". In this embodiment, the tongues are omitted and the tab has an opening 42b, the a pin 44b is assigned. The side walls 42b, 44b, 46b and 48b counteract a relative displacement of the cover flaps 1 4b and 16b. It is obvious that the wall of the opening 42b immediately on the surface of the I.

Pin 44b must be applied to immediately when an opening force occurs, which acts on the lid flaps, the To put tab under tension · Veiter, it is advantageous if the side walls corresponding to walls 26 and 32 in FIG. 2 are curved, as described above is to keep the tab under tension in its locking or locking position.

If so desired, the opening 42b can additionally

009826/0161

ORIGlNAL BATHROOM

be narrowed or kept in the shape of an ellipse, the smallest diameters being slightly smaller than the associated parts of the pin 44b. The smallest diameters run in the longitudinal direction of the container. The walls of the opening grip the pin 44b with a friction fit at the point of the smallest diameter and thereby counteract a detachment of the tab from the pin as a result of a pressure effect on the cover flaps. In this exemplary embodiment, the undercut according to FIG. 6 or the curvature of the pin can also be used.

Another embodiment is shown in FIG. Here, too, the same reference numbers are used, but with the addition of the letter ^N c ". The pin and the opening for this have been omitted absorb opening force directed against the lid flaps.

The degree of stiffness in foam plastic varies over a wide range. If foam plastic with a high degree of stiffness or molded pulp or solid plastic is used, pinching the tongues 38c and 40c in the tongue depressions becomes more effective. Here rounder ", the dimensions" D * and d * ⁿ shown in FIGS. 3 and 4 have substantially the same, the tongues 38c 40c does not jam and in the wells. The stiff material acts

by itself as if the tongues were more or less less soft material jammed. It is obvious, that very stiff material in each of the prescribed embodiments according to FIGS. 1,6 and 8 can be used.

Another embodiment is shown in FIG. Also here, the same reference numbers from the previous exemplary embodiments have been partially adopted and supplemented by a "d". The pin and the opening for this are a

omitted. An opening 202 is provided through which the flexible free end of the tab 34d pushed through becomes, with the tongues 38d and 40d sliding past place on the edges of the opening 202 under the wall 30d and thereby preventing the tab from being pulled out or released from the closed position. The tongues 38d and 40d lie at the edge 204 of the opening and absorb any opening force. It is obvious that only for the tongues 38d and 40d openings can be provided, with the opening 202 being covered, as is the case with respect to the surface 48 in Fig. 1 is done.

FIGS. 10 and 12 show a further embodiment \ for the inventive egg tray. Here, too, the same reference numbers have been used as far as parts are already present in FIGS. 1 to 5, but these are supplemented by a "β". A tab 302 is on the central portion 24e in a suitable manner, e.g. B. by gluing or staples 304 (see drawing) attached. The tab can be made of any flexible material such as polypropylene. The tab has a

narrow part 306 and a pair of tongues 308 and 310 at their free end. An opening 312 ± at in the Wall 28e stamped. The engaging part 314 of the wall has been depressed to provide opening 312, wherein the expressed part at the weakening line 20e for aesthetic reasons to avert dirt outside the box was left in the container.

The width between the ends of tabs 308 and 310. is greater than the corresponding width of the opening 312 and this width of the opening 312 corresponds to the narrowed one Part 306 of the tab. When closing the box the flap is pulled over the middle part 3Oe and the narrowed part 306 is bent downward. Since the Tab 302 is flexible, tongues 308 and. snapping behind the edge of opening 312 and creating such a safeguard against loosening the tab. Any force aimed at opening the lid flaps, is narrowed by the edges of tongues 308 and 310 at the most Part 306 of the tab caught, this being attached to the corresponding areas of the opening 312 rest.
