Abstract

A cup-shaped receptacle (c) has an outer bead (10) in its opening area for clipping on a plastic lid (D). The lid has a circumferentially continuous clamping groove (1) for receiving the bead. The clamping groove is continued outwards by an elastically deformable constriction (14), and inwards by an outer wall (6) of a circumferentially continuous, U-shaped lid recess, the U-web (22) of which is situated below the height position of the constriction and the inner leg wall (23) of which forms apart of a dome (2) wall of a dome which extends upwardly beyond the height position of the constriction. The lid recess extends downwards beyond the height position of the constriction and has an outer diameter at its outer surface which is adapted to the inner diameter of the receptacle wall such that the lid recess functions at least as a centering and guide projection for the lid-clip-on action, which projection slidingly co-operates with the receptacle wall already at least while the bead passes the constriction.

Description

Description of the invention

The invention relates to a cup-shaped receiving device and a cap for such a receiving device. 2 The outer surface of the wall of the outer knee of the recess of the stapled plastic cap on the cup-shaped receiving device in (5 5 253 781 А| extends downward slightly below the position (in height) of the narrowing. The angle of taper and the outer diameter of the outer surface correspond to the angle of taper and the inner diameter of the wall of the receiving device , even when the rounded element is not in substantial contact with the wall of the receiving device, implemented as a rounded element, fully seated in the clamping groove 70. Due to the relatively short outer surface and the large radial size of the O-shaped membrane of the recess for the cap, the clamping groove tilts inward during movement locking; this prevents smooth movement of the rounded element along the entire circumferential length past the taper. It is necessary to first manually center the cap with the clamping groove exactly on the rounded element and then lock the cap by direct pressure on the upper wall of the clamping groove of the remove with a turning motion of the hand. This fixation 72 is inconvenient, too long and increases the risk that the rounded element will not sit properly in the clamping groove. ku in some place on the circumference of the opening of the cup. This can cause liquid to leak out when the full cup is tilted. The cap easily pops off when the receiving device is overfilled, as the opening area of the cup is easily deformed radially.

(05 5 975 344) describes a large-volume injection-molded PE container with a cylindrical wall in the area of the upper opening and a reinforced injection-molded lid, the surface of which is located under the raised upper edge of the lid periphery.

In |OE 10 057 277 A) a narrowed non-flow gate is described, in the upper surface of which (fig. 3 - 6) a conical or cylindrical recess is formed. The bottom of this depression has a wall thinner than the upper surface of the shutter and has crossed, permanently open incisions for the introduction of straw. The shutter is designed to replace the usual s 29 crown cap. Go)

The object of the invention is to create a receiving device, as well as a cap, suitable for the specified receiving device, which ensure the fixation of the cap even by an untrained person, and the fixed cap excludes the possibility of leakage and does not jump off when a full cup is tipped over. Although the invention provides high cap holding force and reliable tightness, cap fixation is easy. high school

Since, according to the invention, the wall of the outer knee extends downward for a relatively long distance, -

The M-shaped diaphragm of the recess for the cap and the wall of the inner knee usually provide a tight centering and guide the protrusion which slides into contact with the wall of the receiving device at least when the rounded element passes the constriction. The clamping groove is automatically and accurately centered on the rounded element, which, after passing through the narrowing, is fixed in almost one movement along the entire circumference in the clamping groove after pressing, in fact, only on the dome of the cap. Due to the sliding contact between the outer surface and the wall of the receiving device, the directed passage of the constriction through the rounded element is ensured, since due to the direction and centering, the rounded element creates a uniform resistance everywhere to the downward movement of the cap. The guide projection converts the pressure applied to the dome into a downward pulling force, uniformly distributed along the taper, which C 70 uniformly pulls the taper past the rounded member until this member seats precisely in the clamping groove. c The centering and action of the conical or cylindrical guide protrusion and the uniform transmission of force provide a significant force of landing between the rounded element and the clamping groove, and this force is provided by a narrow tolerance field of such a landing and elasticity. This eliminates the possibility of leakage of the fixed cap and displacement of the rounded element from the clamping groove when tipping over a full cup. The shape of the dome and recess for the cap form a rigid structure integrated with the cap, thanks to which, when applying a locking force, a reliable fixation occurs without deformation of the cap. Fixed cap significantly increases av! rigidity of the area of the opening of the receiving device and thereby ensures reliable impermeability for leakage.

An important aspect of the invention is the hinged mechanism of continuous circumferential action integrated into the cap, which makes it easier to fix the cap with a quick squeeze of the hand. When pressure is applied to at least the top wall -i 20 of the dome, it moves downward, and the displaced inner knee wall tilts the O-membrane down around the hinge formed at the transition between the O-membrane and the outer knee wall, as soon as resistance to advancement begins to increase taper Through the rounded element. The tilt of the O-shaped membrane temporarily tries to pull the wall of the outer knee away from the inner wall of the receiving device.

The contact between the rounded element and the taper moves the taper outwards and the clamping groove deviates slightly. 52 Clamping force or, if necessary, automatic action, or alternatively pressing on the outer periphery

GF) cap, when pressed down on the dome, causes easy passage of the rounded element in one movement. After removing the force, the hinge mechanism restores the fit of the cap, that is, the O-shaped membrane returns to a position essentially perpendicular to the axis of the cap and firmly presses the wall of the outer knee to the inner wall of the receiving device. The taper is returned to position behind the rounded element until the rounded 60 element fits tightly and hermetically on the clamping groove. The upward dome allows you to activate the coupling mechanism by first lowering the dome relative to the clamping groove and then opening the clamping groove before sliding the rounded element. After that, the dome returns to the raised position. During fixation, the top wall of the dome can be pushed down by pressing until the palm of the hand helps the periphery of the cap to easily complete the fixation process. for The rounded element of the receiving device can be made as a curl, or a whole ring, or a partially curled element, or a half-ring, or an outwardly curved edge flange. In any version, an easy and convenient fixation is provided, which excludes leakage and stably holds the cap. One cap design is suitable for many variants of the rounded element.

The design of the cap is aimed at optimizing and facilitating the fixation, despite the very strong grip in the fixation state. The shape of the mogo ensures relative rigidity of the central zone, thanks to which it can be easily and completely fixed in the clamping groove with geometrical and force coupling by simple pressing in the direction of fixation. This is helped by the guiding action of the guiding protrusion and the temporary opening of the clamping groove by the movement of the dome relative to the narrowing. 70 For this function, it is important that the O-membrane lies essentially in a plane perpendicular to the axis of the cap and that the wall of the inner knee is substantially parallel to this axis. When downward pressure is applied to the cap, these structural features allow the integral hinge mechanism to work reliably, because mechanically the inner knee wall becomes stiffer than the outer knee wall when the O-membrane tilts so that the outer knee wall bends / 5 inside and temporarily opens the clamping groove from the inside.

It is desirable that the outer surface interacts slidingly with the wall of the receiving device even before the beginning of the elastic deformation of the narrowing by the rounded element. As a result, the clamping groove and the taper are located above the rounded element in a precisely centered position, thanks to which the rounded element can prevail the same resistance throughout its circumference and therefore easily and evenly engages with the clamping groove.

When the taper angles of the outer surface and the wall of the receiving device are approximately the same, the outer diameter of the outer surface at the height of the taper must at least approximately correspond to the inner diameter of the wall of the receiving device in the opening zone, so that the centering and guiding action begins even before the rounded element reaches the taper. When the rounded element is fixed in the clamping groove, the softer material of the receiving device bends in the rounded element and the wall, thanks to which a strong positive grip is achieved after locking. In addition, the wall of the outer knee of the recess for the cap i) can slightly bend inward due to the contact pressure between the outer surface and the wall of the receiving device.

The outer diameter of the outer surface in the clamping groove can be significantly larger than the inner diameter c z of the wall of the receiving device in the opening zone, that is, where the inner wall bends outward to the rounded element. This ensures reliable directional action and centering during the entire movement of the rounded element past the narrowing into the clamping groove. The desired diameter difference is approximately 3.595, i.e. between 1.595 and 5.095 depending on the dimensions of the receiving device.

The extension of the outer surface down past the taper is important for centering and steering. Cap o z5 Can be locked by simply pressing on the dome only. The outer surface can be at least 2.5 times higher than the height of the clamping groove. It is even better when such an excess is 3- or even 4-fold. It should be noted that due to the pressure between the outer surface and the wall of the receiving device and due to the large contact area, a very effective seal is provided, which is additional to the seal of the rounded element in the clamping groove. "

A taper angle in the range of approximately 6-122, i.e., a full taper angle of approximately pt") s 12-242, is preferred. A taper angle in the range of approximately 8-102, i.e., a full taper angle of approximately 16-209, s is more preferred. A recess that formed at the point where the top of the upper dome wall meets the outer "" wall of the dome, they help to easily fix the cap and increase the rigidity of the dome. In addition, these recesses show where to place the toes and define the gripping points for convenient removal of the cap from the foot

caps The recesses not only make it easier to grip with the hand, but also define the shoulders of the foot. Each cap (ee) can rest with the shoulders of the depressions only on the upper wall of the dome of the next cap, thanks to which the caps in the foot do not engage. o In order to achieve a strong connection between the rounded element and the clamping groove, which is important for achieving sealing, the radial thickness of the rounded element must exceed the radial internal

The width of the clamping groove. The soft paper or cardboard of the receiving device and the material of the rounded element and bends, respectively, on the inner side and on the outer side, as soon as the rounded element sits in

I will clamp the groove. Flattened zones are flat (i.e. non-linear) contact zones that improve sealing.

The radial thickness of the rounded element should be 10-2095, preferably about 1595 greater than the average radial inner width of the clamping groove. Such dimensions provide a reliable seal with moderate values of effort required to fix the cap in the receiving device.

To facilitate the retaining action of the cap on the rounded element and to gradually flatten the material, the radial inner width of the clamping groove should decrease in the direction opposite to the direction of fixation; име) is expedient with the taper angle of the receiving device wall. In this case, the clamping groove will act as a dummy until the rounded element takes its final position. 60 To strengthen the holding action when fixing the cap on the outer surface of the wall of the outer knee and/or on the inner wall of the receiving device, at least one belt zone with an increased coefficient of friction must be created. This can create increased frictional engagement between the cap and receiver and the hard opening area of the cup.

An important aspect of the invention is also that the taper can consist of consecutive . deeper and more 65 Shallow recesses formed from the outside. It is desirable that deeper recesses are longer in the circumferential direction than shallower ones. This promotes fixation, provides a stable and long-lasting hold and makes the periphery of the cap more rigid.

To facilitate identification of beverage types (e.g., Coca-Cola, Diet Coke, Orange Juice, etc.), upwardly directed protrusions identifying the beverages may be made externally in the wall of the dome's upper wall.

Such protrusions can be push buttons.

Another important aspect is the penetration zone formed in the upper wall of the dome. This zone can have a wall that is thinner than at least the upper wall of the dome, has crossed cut lines, through which it is convenient to insert straw due to the breaking of these lines. Reduced wall thickness facilitates this operation. Thinning of the wall can be achieved by local compression of the cap material. The thin wall area is particularly convenient when the relatively 7/0 Hard Cap has a wall that is slightly thicker than conventional caps. Creating a thinner zone, however, is beneficial in all types of caps as it facilitates straw insertion.

It is advisable to create a penetration zone for the introduction of straw at the bottom of the recess, on-. an example made in the center of the upper wall of the dome. The reduced thickness of the bottom wall increases the rigidity of the dome during the fixation operation.

The penetration zone can be bent inward to facilitate straw insertion and to increase resistance to outward bending under fluid pressure. This deflection also provides automatic closure of the broken incisions after straw withdrawal and in the event that the liquid pressure from the inside acts on the edge parts of the broken incisions. The recess contour, which corresponds to two ellipses with mutually perpendicular main axes, increases the rigidity of the dome and gives an attractive appearance to the dome. It is advisable to make incisions along the main axes of both ellipses. It may be sufficient to restrict yourself to creating a thin core in the wall instead of providing straw insertion.

A further aspect of the invention is an easy-to-lock cap for a double-walled conical paper or cardboard receiving device. Such receiving devices usually have such an opening zone, in which the inner wall of the receiving device is deformed outwards and connects with the outer wall of the receiving device. A rounded element is formed at the upper end of the inner wall of the receiving device. The taper angle of the conical inner wall of the double-walled receiving device is greater than i) the extended lower opening zone, which forms an extension of the lower wall of the receiving device by a circumferential shoulder and has a zero taper angle or an angle smaller than that of the lower wall of the receiving device.

The cap on the rounded element contacts the inner wall of the expanded opening zone through a centrifugation-directing cone when the rounded element comes into contact with the constriction. In the process of fixation, the cap is centered and directed over the rounded element. The centering-directing protrusion is retracted - inward due to the deformation that occurs between the dome pressed down and the clamping groove such that Ge! in such a way that the rounded element passes through the narrowing more easily. After fixing, the cap provides protection against leakage and is rigid in the opening area of the receiving device. at

It is desirable that the angle of conicity of the outer surface or the centering and guiding projection is equal to 0 or less than the angle of conicity of the inner wall of the receiving device. The rigid centering projection places the rounded element in a tight watertight position in the clamping groove and can even cause the opening area of the double wall receiver to deform to increase the stiffness of the edge area and a better seal. "

In this case, the centering-directing protrusion should continue downwardly directed downward into the stepped parts of the wall of the outer knee, which is given the proper dimensions for interaction with the wall of the receiving device under the conditions of landing under the influence of yew. The part directed downwards must have a taper angle, ;" which is essentially equal to the taper angle of the inner wall of the receiving device below the stepped upper opening zone. The interaction between the stepped part and the inner wall of the receiving device increases the Sealing effect even deep inside the receiving device. o The embodiment of the invention is described with reference to the drawings, in which: Fig. 1 is a side view of the cap, o Fig. 2 is a section along the axis of the cap of Fig. 1,

Cap OO (fig. 1), intended for use with a cup-shaped receiving device C, made of paper or cardboard, or plastic, for example, formed from elastic plastic foil, with a wall thickness of, for example, 0.3-0.5 mm. The cap is adapted for fixation in the opening zone 9 of the receiving device C in such a way that it closes. secures this receiving device, eliminating the possibility of liquid leakage, and does not disconnect even if the receiving device is tipped over. The cap O has a circumferential continuous clamping groove 1 on the periphery above the plane where the dome 2 covers the inner side of the clamping groove 7/o 1. The dome 2 is separated from the clamping groove 1 by a circular, essentially uniform recess M in the cap and has a substantially flat upper wall 5 and several recesses 3 distributed around the circumference. Relative to the clamping groove 1, the wall 4 of the outer knee of the recess M of the cap (Fig. 2) noticeably extends down beyond the plane of the clamping groove 1.

The cap O (Fig. 2) is fixed on the area 9 of the opening of the receiving device C (Fig. 3) by applying pressure K, /5, for example, to the upper wall 5 of the dome in the direction of fixation. The upper wall 5 of the dome extends substantially parallel to the plane of the cap O. The recess M in the cap is limited by the wall 4 of the outer knee, which in this embodiment tapers downwards, the lower O-shaped membrane 22 and the wall 23 of the inner knee, which forms the outer wall of the dome extending upwards. The wall 4 of the outer knee has an outer surface 6, which passes into the clamping groove 1. The outer surface b has a taper angle a/2, which can correspond to you, at least essentially, the conicity angle a/2 of the wall 7 of the receiving device.

At the lower end of the wall 7 of the receiving device (Fig. 3) is the bottom 8 of the receiving device, and the zone 9 of the opening of the receiving device is limited by the wall 7 and the protruding rounded element 10, preferably the so-called curled rim made of cardboard or paper of the receiving device C If receiving device is plastic, the rounded element 10 can be made by injection molding. c The rounded element can also be a semi-curved or outwardly curved rim flange.

Fig. 4 illustrates the cap Y on a rounded element made as a curled rim 11. On the rounded i) element 10 lies the narrowing 14 of the cap 0.

At its upper end, the wall 4 of the outer knee is continued by the wall 12, which is parallel to the plane of the cap, and the visor 13, which extends approximately parallel to the axis of the cap Y down to the narrowing 14. The narrowing 14 can be a groove-like depression from the outside and form an internal rounded comb 15 The comb 15 and the narrowing 14 can be continuous around the entire circumference, or can be formed by separate local recesses between which (dashed lines) the outer contour is approximately preserved. Gee!

The narrowing 14 extends down the inwardly inclined wall 16, which forms a fixing slope 17. From the wall 16, the visor 18 extends downwards and ends at the outer flange 19. The height of the visor 18 can be less than the one shown. co

The radial thickness of the rounded element 10, measured at the transition from the straight wall 7 of the receiving device to the bend of the rounded element 10, may exceed the radial inner width y1 by 10 - 2090, preferably by about 1595. In the clamping groove 1, the radial inner width y1 gradually decreases " from the narrowing 14 to the wall 12, preferably with a taper angle a/2.

Clamping groove 1 determines the distance | between the comb 15 and the inner side of the wall 12. The wall 4 - c of the outer knee extends down the narrowing 14 by a distance 11, which can exceed I at least by 2.5 times, preferably by 3 times, best by 5 times or more. "» The outer diameter 01 of the outer surface 6 of the wall 4 of the outer knee at the height of the narrowing 14 (for example, the comb 15), at least approximately corresponds to the inner diameter 07 of the wall 7 of the receiving device near the rounded element 10, that is, at the transition from the straight wall 7 of the receiving device to the bend ( ee) of the outwardly rounded element 10. The outer diameter 02 of the outer surface 6 of the wall 4 of the outer knee at the connection with the wall 12 is significantly larger than the inner diameter О07, preferably by approximately 1.595 - 5.095, preferably 3.590. (Ce) When applying pressure To the dome 2 (Fig. 4), the outer surface 6 is in sliding contact with the wall 7 of the receiving device -1 50 until or at the moment when the narrowing 14 is reached by the rounded element 10. The recess M of the cap forms a centering-directing protrusion K, which supports and enables easy fixation cap 0. It is advisable to have a sliding contact even before the rounded element 10 reaches the narrowing 14. When the cap is pressed further, the rounded and the element 10 elastically deforms the narrowing 14 outwards, and the rounded element 10 is also slightly deformed when passing through the comb 15 and then pinched in . clamping groove 1 (Fig. 5). Areas with a cross-shaped filling in Fig. 5 define the compressed zones 20, 21, formed in the rounded element 10 and in the wall 7 of the receiving device, which contribute to compaction, retention and increase in rigidity. In another version, the wall 4 of the outer knee can slightly bend inward (dashed lines 21. i.e.) The cap О fig. The narrowing 14 (Fig. 7) is formed by successive successive deeper and shallower 60o recesses 16a, 166, which form a serpentine ridge 15".

The deeper recesses 1ba in the circumferential direction may be longer than the shallower recesses 165. Also, the dashed line 19" here shows the shortened visor 18.

The recess 24 (fig. b6) has a bottom zone 25 of the dome of a limited size, substantially parallel to the upper wall 5 of the dome. The wall thickness of the SO cap is essentially constant. Only zone 25 is made thinner (thickness x1), 65 for example by compression of the material, and it is located in the center of the upper wall of the dome. For the introduction of straw, the zone 25 has crossed incisions 26 intended for breaking. It is desirable that the zone 25 is curved towards the inner side of the dome 2.

Indentations З in the transition from the upper wall 5 of the dome to the wall 23 of the inner knee increase the rigidity of the dome 2 and allow you to grab the cap Ю with your fingertips, for example, for easier

Pulling out the cap Or from the foot of the caps or putting the cap on the receiving device C. The fixing force K can be applied through the recess 3. However, it is preferable to fix it by pressing the palm of the hand on the upper wall 5 of the dome.

The wall 4 of the outer knee can have at least one circumferential circumferential part ZO (fig. b) with an increased coefficient of friction to increase the holding action after fixing the cap O. The part ZO can be located 7/0 higher than shown, or be narrower or wider. A corresponding zone with an increased coefficient of friction can also be created on the wall 7 of the receiving device either instead of the part 30 or to interact with the part 30 of the cap 0.

A circular continuous hinge mechanism M is built into the cap O, formed with the structure and shape of the dome 2 and recess M of the cap. This mechanism helps in fixing the cap O (fig. b -10).

The hinge mechanism M of the OO cap consists of dome 2, wall 23 of the inner knee, O-shaped membrane 22 and wall 4 of the outer knee. The transition of the wall 4 of the outer knee to the O-shaped membrane 22 and the transition from the O-shaped membrane 22 to the wall 23 of the inner knee form a hinge 23. The wall 23 of the inner knee extends essentially parallel to the longitudinal axis of the cap, and the O-shaped membrane is flat and perpendicular to the axis of the cap. It should be noted that due to the rigidity of the dome 2 and the smaller diameter of the wall 23 of the inner knee compared to the larger diameter of the wall 4 of the outer knee, the wall 4 of the outer knee bends inward more easily than the wall 23 of the inner knee. This circumstance is used to temporarily open the clamping groove 1 and facilitate fixation.

In Fig. 8, the cap O rests on the rounded element 10 of the receiving device C in such a way that the circumferential extension of the narrowing 14 is centered on the rounded element 10. The wall 4 of the outer knee contacts the wall 7 of the receiving device. Now apply a fixing force K, for example, to the upper wall 5 o the dome with the palm of your hand to move this wall down.

When the constriction 14 sits on the rounded element 10, a reactive force B acts against the fixing force P... The wall 23 of the inner knee tilts the O-shaped membrane 22 down through the internal hinge 29 in the transition from the wall 23 of the inner knee to the O-shaped membrane 22. As a result of the radial stiffness of the dome 2, the inclination |W- Hezo of the membrane 22 generates a force 28, which acts on the external hinge 29. The force 20 separates the wall 4 of the external knee from the wall 7 of the receiving device in such a way that the clamping groove 1 can open - even somewhere on the inner side. The visor 28 is moved outwards by the firing 27 reactive force B, (o) as a result of which the clamping groove 1 can open on the outer side. Under the action of the locking force K and due to the fact that the upper wall 5 of the dome has shifted downward and possibly presses on the wall 12, the rounded element 10 slides past the narrowing 14 until it is fixed in the clamping groove 1. (ee)

Fig.10 illustrates the state after the disappearance of the fixing force K. The O-shaped membrane 22 is returned by the force of elasticity to a position essentially perpendicular to the axis of the cap and presses the wall 4 of the outer knee to the wall 7 of the receiving device. The spring force also turns the O-membrane. The clamping groove 1 firmly holds the rounded element 10. The centering protrusion K and the clamping groove 1 rigidly fix the zone 9 of the opening of the receiving device C. The recess 24 (Fig. 11) resembles a four-leaf clover in shape, that is, two identical ellipses with mutually perpendicular main axes . Lines 26 of the cut in zone 25 extend along the main axes of both ellipses. Figure 12 shows an enlarged view of the difference between wall thicknesses y and x1 in zone 25. Zone 25 may curve inwards as shown or be parallel to the top wall 5 of the dome. It is not necessary to reduce the thickness x1 of the wall throughout the zone 25. It is enough to have only a thin-walled central part of the zone 25, for example, formed by compression of the material during the manufacture of the cap U. (ог) The radial width of the annular O-shaped membrane (fig. b -10) can be approximately 1095, and the diameter o of the upper wall 5 of the dome is approximately 6095 of the outer diameter of the cap 0.

The embodiment of the cap O in fig. 13, 14 is similar to the embodiment illustrated in fig. 6-142, but additionally has (Ce) evenly spaced protrusions ba for distinguishing drinks. There are, for example, four distinctive oval -1 50 protrusions ba, which have markings and/or push buttons at the top. Such elements are common in existing caps. Ba protrusions are located at a small radial distance from the outer edge of the upper one

Ko) of the wall 5 of the dome and also from the central recess 24. In addition, the recesses Z are made with an undercut and therefore they are easy to grasp with the fingertips when the cap OO needs to be removed from the foot with several caps (fig. 15). Each recess has a lateral shoulder Za, which can serve as a stop when laying in the foot, when the shoulder

Za rests on the upper wall 5 of the dome of the next cap ЮО in the foot. The Za shoulder prevents mutual adhesion of the caps, since the caps in the foot contact each other in places where the Za shoulders rest on the upper wall 5 of the dome and where the walls of the outer knee are in contact. This allows you to have an orderly and dense foot, from which you can conveniently remove each cap O. In the above embodiment, 8 recesses 3 are provided.

The OO cap in Fig. 13-15 also has a centering-directing projection K (directing cone) and a hinged 60 mechanism M to ensure fixation.

Fig. 16, 17 illustrate the receiving device CO with a double wall and easy fixation. Such a receiving device has an inner wall 7 and an outer wall 7c with an air gap between them for thermal insulation.

A rounded element 10 is formed on the upper end of the inner wall 7. The double-wall receiving device CO has a taper angle a/2 that continues to the rounded element 10. In the forming process 65, the upper part of the inner wall 7 expands outward so that in the opening zone the angle taper a/2 is smaller than a/2 and may even be equal to 0, and at the same time a shoulder 705 is formed. The cap O for the receiving device CO has the above-described centering-directing protrusion K, formed in such a way that the outer surface b is either cylindrical (as shown), or has an insignificant taper angle p/2, moreover

O " r/2 " o/2. The outer surface 6 or wall 4 of the outer knee is extended inwards by the stepped part 46 of the wall to form a shoulder 4a. Part b of the outer surface of part 465 of the wall has a slope with a taper angle os/2. The bottom part of the centering and guiding protrusion K is formed by an O-shaped membrane 22, which extends, in fact, perpendicular to the central axis of the cap. Diameter O1 of the outer surface. 6 essentially corresponds to the diameter of zone 7 of the opening in the vicinity of the rounded element 10. In zone Z, the inner parts of the inner wall 7a of the receiving device, the outer parts of the wall 4 of the outer knee and the part 70 of the wall 45 are shown deformed, in a position of close contact under pressure, when the cap О is completely fixed on the receiving device SO.

The cap Y is centered on the receiving device CO with a double wall in such a way (Fig. 16b) that the rounded element 10 approaches the narrowing 14 from below. In this case, the outer surface 6 is already in contact with the inner wall 7a of the receiving device in the opening zone for proper centering and 75 directing the cap OO when applying the fixing force K, for example, to the upper wall 5 of the dome (not shown in Fig. 16b).

As the locking force forces the taper 14 through the rounded member 10, the outer surface 6 guides the cap Y. When the O-shaped membrane is tilted downward as described, the wall 4 of the outer knee moves slightly inward and the taper 14 is pushed outward. Thanks to this, the narrowing 14 easily slides over the rounded element 10 and reaches the position shown in Fig.17. After that, the rounded element 10 is clamped from the outer and inner sides. The contacting parts (20, 20) of the wall undergo compression, and the shoulder 4a either rests on the shoulder 7p, or at least approaches it. The contact pressure in part 201 creates an additional sealing effect in addition to the sealing effect formed by the interaction between the clamping groove 1 and the rounded element 10 and between the wall 4 of the outer knee and part 7a of the inner CM wall of the receiving device. The rigid structure of the dome of the U cap can even force part (5) 7a of the inner wall of the receiving device in a position parallel to the wall 4 of the outer knee, thus providing a high holding force and significantly increasing the rigidity of the opening zone of the receiving device CO in the closed state. In addition, the interaction between the arms 4a, 75 can limit the locking movement and thereby prevent excessive deformation of the rounded element. The support arms 4a, 705 can even hold the CM rounded element 10 and the clamping groove 1 in a predetermined closed position, which M provides reliable protection against leakage and a significant holding force for the cap 0.

Fig. 18 contains a cross-section of the cap OO in the fixed position on the single-wall receiving device Co 0/0) (Fig. 5). The rounded element 10 is completely curved inwards. The clamping groove 1 of the OO cap has a round cross-section. Crosscut zones are places of close contact, for example, even slightly pressed surface parts. A tight contact between the clamping groove 1 and the rounded element 10 is provided more than on the 1802 circumference of the rounded element 10. The wall 4 of the outer knee significantly increases the rigidity of the upper opening zone against radial deformation.
