Description

Description of the invention

This invention relates to a container in the form of a tank, in particular, a bucket with a lid, as indicated in the defining part 2 of the first clause of the claim.

A known container in the form of a tank of a similar type, protected (by the patent document EP 0565967 B21), in which the petal for unhooking and lifting the lid is held with the possibility of rotation parallel to the direction along the circle on the horizontal axis of rotation on the circular flange of the container. In other words, the axis of rotation is located parallel to the lower free face flap, while the specified free face is located 70 coaxially with the lower free circular face of the circular flange of the container. The outward facing zone of the surface of the flap is the working surface when the lid is unhooked and lifted. In order to provide the required arm length of the flap lever, in a known container in the form of a tank, the specified flap must protrude beyond the lower edge of the circular flange of the container. However, the unhooking lift of the lid by means of a flap that turns outwards in the direction of the lid lacks smoothness and is carried out in jerks. In addition, when performing the opening movement 72, the user applying this k design, bends down to place the thumb on the lid, while the other fingers grasp the petal from behind, the force of the thumb subsequently resisting the movement, which causes the lid to disengage.

The technical problem solved by the present invention is to create a container in the form of a tank, in particular a bucket equipped with a lid, similar to the one disclosed in the introductory part of the description of the present invention, the opening mechanism of which would be more convenient to maintain, in which smooth and uniform movement of the lid would be achieved when unhooking lifting.

In this container in the form of a tank, in particular in a bucket equipped with a lid, shown in the introductory part of the description of this invention, the technical problem is solved due to the features set forth in clause 1 of the claims. c 29 The features that make up the essence of the invention provide conditions under which the length of the arm of the lever for opening the cover (Ho) with the application of less force can be ensured, thanks to the increase in the length of the petal in the peripheral direction, which is not difficult to achieve, while the petal is not necessarily must extend downwards beyond the circular flange of the container. The presence of a corresponding configuration of the cam groove (curvilinear track) provides the possibility of a uniform and jerk-free uncoupling movement when the cover is lifted. The applied actions do not require the application of any counter-pressures to the lid, except for the pressures that in most cases affect the wall of the container body.

The rotary axis of the petal can be strictly perpendicular, and therefore parallel to the theoretical axis c o of the container, or according to the features of the second clause of the formula of this invention, it can be inclined in the direction c of the specified axis of the container and/or in the theoretical plane X-Y. The last solution is more preferable in the sense of providing a more intensive movement during the uncoupling lifting of the cover. in

If the petal is located on the body of the bucket, the solution based on the features set forth in clause 3 of the formula of this invention is preferred.

The features of paragraphs 4 or 7 of the claims characterize a rotary axis, the presence of which is easy to ensure. "

Effective rotary devices for attaching the flap to the container body are provided in accordance with C 40 features, protected by clauses 5 or 6 or one of clauses 8-10 of the formula of this invention, in the form of a single-armed or double-armed lever design, respectively.

From" The signs set forth in at least one of clauses 11-143 of the formula of this invention additionally ensure the preservation of the initial state of the container in the form of a tank, in order to track the fact of the initial opening of the specified container. The petal for detachably lifting the lid can be equipped with a means 45 of protecting the integrity of the package or a device for detecting the fact of illegal opening in the form of a film or tabs that connect the petal to the circular flange of the container and are elements of a single design, which

Ge | break off or open when the petal is first raised. Violation of the structural integrity of the device for detecting unauthorized disclosure can be performed without any complications in a container in the form of a tank manufactured in accordance with another example of the implementation of the invention, where such a violation

Ge) 20 is performed in a less destructive way. When such a device is introduced into the structure to detect illegal opening or to protect the integrity of the structure, the connection, which is an element of a single material structure made as a whole, does not break during opening, the implementation of which, of course, requires the use of an appropriate amount of force and intensive movement , but at the end of the movement that lifts the lid, it still continues to remain in the state of the locking connection, the changed state of which, however, is irreversible and therefore clearly demonstrates the fact of opening. Additional features that provide the specified design improvement

HF) devices, defined at least in one of paragraphs 14-16 or 17-27 of the formula of this invention. In this sense, the essential difference of this technical solution lies in the coordination of the movements of the petal and the fixing loop or about the clamp. In this case, the configuration of the locking clamp is such that at the beginning of its turning movement, it is directed under the circular face of the circular flange of the container. Simplicity and convenience of the locking device 60 is provided due to the fact that it is located on the adjacent support leg of the circular flange of the container.

The signs set forth in paragraphs 28 and/or 29 and/or 3 of the formula of this invention provide great convenience in the service process when opening the container.

The container shown in Fig. 1-7 in accordance with the first example of the implementation of the invention is a bucket 10, width 10, 10", made by the method of molding from a plastic material, the body of which is closed by a lid 12, also made by the method of molding from a plastic material. from the further description, it is clear that the lid 12 i) is located on the body 11 in a fixed state in such a way that it can be opened only with the help of an auxiliary device facilitating the opening process 13, 13", 13", respectively, which is located on the bucket 10, being an integral element of its design. In the area of its upper face, which is some distance from the bottom and defines the border of the bucket opening, the body 11 of the bucket 10, 10", 10" is made in one piece with a circular flange 11, which in cross section resembles the shape of a vault and, projecting, at a distance surrounds the body 11 from the outside. n 18 of the flange, forming a support for the cover 12, is connected by the second wider section 19 of the vault. The second section 19 of the vault has a section 21 of a flat surface, which is attached to the ridge 18 and is separated from the free lower section 24 of the flange behind it by a groove 22 directed towards the body 11 (Fig. 6B and 7). In the transition zone to the free section 24 of the flanges, the groove 22 is deeper than in the transition zone to the section 21 of the flat surface. This configuration provides a support surface for the face of the lid, which will be described below, in the area of the lower inner wall 26 protruding beyond the upper inner wall 25.

The cover 12, identical for all variants, has a flat cover 31, which is equipped in the area of its upper surface with a perpendicularly protruding centering rim 32 located around the circumference. on the outer circle on the cover 31 is a circular rim 33, which on the inner side has a formed u? the configuration corresponding to the circular flange 16 of the bucket, while the lower free face 34 of the flange, being in the closed fixed position, is located on the support surface 26 in such a way that the sections of the outer surface of the circular rim 33 of the lid and the free flange section 24 of the circular flange 16 are concentric -I in relation to each other. In addition, the circular flange 33 of the lid is also equipped with an internal, circumferentially located and protruding locking shoulder 35, which in the closed locking position of the lid 12 is fixed on the bucket 10, 10, 10" behind the upper inner wall 25, entering the groove 22 of the circular flange

Go! 16. Since the cover 12, thus fixed on the bucket 10, 10, 10", cannot be lifted from the body 11

Buckets without the help of any tool, i.e. by hand, for this purpose an auxiliary opening device 13, 13", 13" is provided. c As shown in Fig. 1-4, the auxiliary opening device 13 is equipped with a petal 36, which is placed on the second part of the vault 19 of the circular flange 16. For this purpose, the second part of the vault 19 of the circular flange 16 is equipped with a cutout 37, in which, with the possibility of turning on one a petal 36 is installed at the end. The petal 36 in the cut-out 37 is limited on one circular end (end) by a rotary face 38, and on the other circular end by a free face 39, formed in a circular direction towards the ridge 18, bent along the curved face of the cam

F) the groove 40 and the stepped lower edge 41 distant from the crest, which is located coaxially with the lower edge 42 of the circular flange 16 in the direction of the turning face 38, and protrudes at the other end. The turning face 38 extends over a significant part of the further section 19 of the vault of the circular flange 16 closer to the ridge 18. The free face 39 because the petal Zb is located, basically, parallel to the turning face 38 in a separate zone of the section 24 of the free flange and ends before the groove 22 on the outside of the cover 12. The cam face 40, made with a given configuration due to the shape of the cam, which will be described below, extends in a circular direction along the section 21 of the flat surface, the groove 22 and a separate zone of the section 24 of the free flange. The cutout 37 in the circular flange 36 has a turning face 43, which is parallel to the turning face 38 of the petal 36 and is at 65 some distance from the face 43, while the free face 44, the zone of which is located in the area 24 of the free flange, is parallel to the free face 39 of the petal 36. There is a narrow gap between the corresponding faces of the petal 36 and the circular flange 16 mentioned above. The rotary face 38 of the petal, which faces the rotary face 43 in the peripheral area of the circular flange 16, is formed on the rotary face 43 with the help of a thin-layer (film) hinge 44, as a result of which the petal 36 acquires the ability to rotate around the rotary axis formed in this way. The cutout 37 in the circular flange 16 can have the shape of a quadrilateral. In the illustrative examples of the invention, the longitudinal face 46 of the cutout 37, which connects the faces 43 and 44, is located parallel to the cam face 40 of the petal 36.

The curved cam face 40 of the lobe 36 has a sinusoidal configuration, in which a surface with a concave depression configuration, which extends from the turning face 38 or thin layer hinge 45, 7/0 adjoins by means of a convexity of the opposite direction configuration, equipped with a straight end, to the free face 39 The cam face 40 in the first embodiment shown in Fig. 1-4 and in the second embodiment shown in Fig. 5A, B and bA is only partially covered by the circular rim 33 of the cover, i.e., approximately one-third of its end face of the zone remains visible in the zone of the section 24 of the free flange.

The functioning of the petal 36 as a device 13 contributing to the process of opening the cover occurs in such a way that the petal 36 is captured in the area of its free circular end, for example, in the area 50 of the engagement of the petal, which increases in width or extends under the lower face 42 of the flange 16 , and turns around the vertical pivot axis 45 outward, that is, away from the body 11 of the bucket. During this rotary movement of the cam face 47 outwards, the lower face 34 of the cover 12 is captured in such a way that with the subsequent rotary movement of the petal 36, the cover 12 is moved outwards with the help of the cam face 47, which is moved outwards and rises, opens and is directed upwards (Fig. 3). As soon as the cover 12 rises in the area of the petal 36 with the help of the device 13, facilitating the opening process, in the area of the lower face 12 there is an opportunity to put your hand under the cover 12 and pull the cover. Thanks to the thin-layer hinge 45, the petal 36 moves back to its original position, as a result of which, for example, after using the contents of the bucket 10, the cover 12 can be fixed on the bucket again. high school

In the examples given, the invention is implemented using the design variants of the devices 13, 13", 13", contributing to the opening of the lid, respectively placed on the body 11 of the bucket 10, 10, 10", additionally provided (8) devices 15, 15, 15", which respectively provide protection of the primary integrity of the container packaging and testify to the absence of intentional premature opening, based on the condition of which it is possible to conclude whether the auxiliary devices 13, 13", 13" were used at least once to remove the cover 12 from the body 11 of the bucket. In the first example of implementation, Fig. 1-5, the device 15, which provides protection of the primary integrity of the packaging of the container and indicates the absence of premature opening, is formed by tear-off tabs 51 or a tear-off film (which is located) between the cam face 40 of the petal Zb and the longitudinal face 46 of cutout 37. In this case, this device 15, which provides protection against premature opening, is located in the area of the rotating face 38 and the longitudinal face 46, which is visible from under the fixed cover 12 on the free flange section 24 of the circular flange of the 16. This means that if the lid 12 in the fixed state is lifted for the first time by means of the rotary movement of the petal 36 around its vertical rotary axis 45, the tear-off tabs 51 or the tear-off film will be damaged, which will indicate that this container has already been opened once.

The second embodiment of this invention, shown in Fig. 5A, B and bA, B, differs from the first embodiment shown in Fig. 1-4 in that the vertical pivot axis 45 is absent in the area of the circular flange 16, but is located outside body 11 of the bucket 10. In other words, the petal Z6' with the help of a thin-layer hinge is held rotatably together with its rotating face 38 outside the body 11 of the bucket. ;" In this embodiment of the invention, the petal 36" is located between its pivoting face 38 on the body 11 of the bucket and its free face 39 or gripping section 50 with a curved section 52 that protrudes almost 902. As was described in connection with the first embodiment, the cam face 40' (the face of the curvilinear groove acting as a cam) extends from the free face 39 along the flat longitudinal zone and the curved area 59 of the petal 39 in the direction of the rotary face 38. In this case, the curved configuration of the cam face 40 almost completely corresponds to the configuration of the cam face 40 of the flap 36 according to the first embodiment of the invention. In this connection, it should be noted that when the flap 36 of the device 13, contributing to the opening of the lid, is activated, the same actions are performed that ensure fixation and lifting of the lid. o Device 137, which contributes to the opening of the lid, can be equipped with a device 15, providing protection from the primary integrity of the packaging of the container and certifying the absence of t of premature opening, which is used in the first example of implementation of the invention, shown in Fig. 1-4 in the visible zone between the petal 36 and the circular flange 16. In the second example of implementation, shown in Fig. 5A, 58 and bA, 6B, the above device is used 15, which ensures the protection of the primary integrity of the container packaging and certifies the absence of premature opening, in the form of locking protrusions 53 and 54, and the locking protrusion 53 is formed in (Ф, the form of a protruding section, which is a continuation of the curved section 52 of the petal 36, and the locking protrusion 54 ko is formed in the form of a protruding area on the foot 55, which finds support in this area of the circular flange 16, namely near the petal 36, in the direction of the body 11 of the bucket. Fixing protrusions 53 and 54 are placed in mutually opposite positions and pass under the groove 22 or are fixed on the lower face 34 of the cover 12 in an accessible position in this area relative to the height of the petal 36' and the circular flange 16. Fixing protrusions 53 and 54 are equipped with teeth made on end surfaces facing each other, detailed images of which are not shown in the illustrations.

As for the position of the cover 12, in which it is fixed on the body 11 of the bucket, as shown in Fig. 5A and b5 5B, the two locking protrusions 53 and 54 with their serrated end faces are located at a certain distance from each other. With the open position of the petal Z6' and the raised cover 12, as shown in Fig. bA and

6B, the locking tab 53 appears to be very firmly engaged or fixed in the locking tab 54 of the circular flange 16, due to the pivoting movement of the flap 36. In other words, due to the mutual engagement or locking arrangement of the two tabs 53 and 54, the tab 36 remains in the pivoting position shown in FIG. .bA and 68, or in the rotated open position, in any case indicating the fact of the first opening movement, which is associated with a smaller opening angle of the petal 36", which is shown in the enlarged for better visibility image in Fig.bA and 68. In the event that the petal 36' moves in the direction opposite to the direction of the opening movement, in the direction of the arrow M, when the gripping portion 50 is directed toward the body 11, the state of mutual engagement or fixation still continues to be maintained, taking into account the elasticity of both locking lugs 53 and 54. This also means that such a non-disengaging connection of the two locking lugs 53 and 54 is maintained when the cover 12 is fixed again on or over the circular flange 16 of the body 11. Thus, the damage to the device 15, which provides protection of the primary integrity of the packaging of the container and certifies the absence of premature opening, remains visible. The cover 12 is fixed in the given position, as described above, or with the simultaneous movement of the petal 36 in the direction of the arrow 75 M, or with the help of an inclined bypass surface (not shown) in the area of the cam face 40 of the petal 36 on the selected area of the cover 12.

According to a separate variant (not shown), the device 15, which ensures the protection of the primary integrity of the container packaging and indicates the absence of premature opening, according to the second example of the implementation of the invention, shown in Fig. 5 and b, can also be made in such a way that the elements in in the form of the described locking protrusions 53 and 54 have the form of deformable fingers, which in the primary locking position of the lid 12 on the body 11 overlap in such a way that the deformable finger, the petal 36", when viewed from the outside of the bucket, is located on top of the finger that is deformed, on the circular flange 16. During the opening movement of the petal Zb, corresponding to the view in Fig.b, one of the deforming fingers changes in such a way that the overlapping of the deforming fingers alternates, i.e.

The toe now serves as a support from the inside compared to another deformable toe located opposite.

This state remains unchanged during the rotary motion of the petal 36", shown by arrow M. i)

In the presence of the protrusions 53 and 54 shown in the illustrations, as well as in the presence of the deformable fingers described above, which are not shown, the recovery of the destroyed device 15, which provides protection of the primary integrity of the container packaging and certifies the absence of premature opening, is prevented in a similar way as when the reverse the movement of the petal 36", in accordance with the indication of the arrow M, is prevented by means of a support foot 56, which protrudes along a curve from the body 11 of the bucket and to which the petal 36! begins to fit tightly with its internal reinforcing feet 57. ee)

In the variant shown in Fig. 7, the cam face 40" of the petal 36" extends only down to the groove 22 in the circular flange 16, in other words, the cam face 40" is completely within the lid 12 in the so 3z5 fixed position on the body 11 of the bucket and therefore it remains invisible. The opening and lifting movement - occurs according to the same principle as during the turning movement of the petal 36' outward, at the same time, due to elasticity, a downward movement is also observed, and this downward movement ensures the capture of the cam face 40" from below lower face 34 cover 12. "

In the variant shown in Fig. 7, deformable feet 51" or a corresponding deformable film 70, in addition to them or instead of them, are used as a connection between the free face 39 of the petal Z6" and the free 8c face 44 of the cutout 37. Deformable paws or films are formed on the face and, in the original unopened state, hook the adjacent face from behind. Being removed from this position, under the action of deformation forces, they "" move forward, if the petal 36" is turned for the first time. Recovery of the deformable feet 51" or the deformable film is not possible due to the presence of a stop (not shown) to limit reverse movement relative to the C6" petal. - And the variant shown in Fig. 7 also differs from the examples of implementation of the invention in Figs. 1-4 and Fig. 5-6 by the position of the rotary axis, and therefore also the thin-layer hinge 45". If in the examples of implementation mentioned above, the rotary axis 45 passes mainly vertically, in other words - parallel to the theoretical axis of symmetry (ee) Z (in the case of a cylindrical bucket, parallel to the axis of rotation), while the axis 45 of rotation, taking into account the inclination of the second section 19 of the vault at an acute angle in relation to the body 11 , can be, accordingly, inclined from the X-Y plane to the X-7 plane relative to axis 5. Features of the variant shown in Fig. 7 include a rotary axis or (Che thin layer hinge 45", inclined at an angle to the X-Y plane , that is, located at an acute angle relative to the free faces 39, 44 facing outwards. Such a solution contributes to the lifting of the cover 12 during the rotation of the petal 36", when the pivot axis 45" tilts from the bottom up in the direction of the free face.

In the embodiment shown in Fig. 7, the film providing protection against intentional unauthorized opening of the cover can be placed between the cam face 40", which is itself hidden from view, and

Ф, the longitudinal face 46, if viewed through the inspection window built into the wheel rim 33 of the cover. devices 15, 15, 15", which provide protection of the primary integrity of the container packaging and testify to the absence of intentional premature opening of it, can be used in such a way that the gripping area of the 50 petal Zb, 36, 36" is located in the zone that is included in the main section of the petal, shown by the weakened line 58 (indicated by a dashed line only in Fig. 5A), around which the gripping section 50 constantly oscillates or deviates from before the petal 36, 36, 36" makes a truly opening movement. Thus, the destruction of the initial state of the node becomes absolutely obvious. In this situation, the slightly curved gripping section 50 does not prevent the lid 12 from being re-fixed on the bucket body 11. It should be noted that such a solution 65 can be used instead of or in addition to the devices already described, which ensure the protection of the primary integrity of the container packaging and indicate about the absence of deliberate premature disclosure.

Another variant of the second embodiment of the invention, shown in Fig. 5 and 6, confirms that the petal 36 can extend in the zone of the free flange section 24 of the circular flange 16 and in this case it is turned by its two opposite end faces 38, 39, separated by a gap, to the free end faces 43, 44 of the circular flange 16. In this case, in the zone, asymmetric in the longitudinal direction and distant at a certain distance from the gripping area 50, the petal 36 is equipped with a rotary foot made integral with the petal and running at an angle, the end face of which turns into a thin-layer hinge and is thus rotatably connected to the body 11 of the bucket. In this regard, it can be stated that the device 15, 15, 15", which provides protection of the primary integrity of the container packaging and indicates the absence of intentional premature 70 opening of it, can be located, according to the above features, on the edge of the petal 36, remote at some distance from the catchment area 50.

The size of the cutout 37 in circumference, as well as the circular length of the petal Zb, 36, 36" depend on the given dimensions of the arm of the lever, which works effectively when lifting the lid 12 without detaching.

The container, according to the third example of the implementation of the invention, shown in Fig.8-13, is a bucket 7/5 110, made of plastic material, the body 111 of which is covered with a cover 112, also made of plastic material. The cover 112 is fixed on the body 111 in such a way that it can be opened only with the help of the device 113, facilitating its opening, and this device is made in one piece with the bucket 110.

In the upper end section of the container, located at a certain distance from its bottom part and the defining border of the opening of the bucket, the body 11 of the bucket 110 is equipped with a circular flange 111 made integral with the bucket, and this flange surrounds the outside of the body 111, protruding beyond its borders, and has a shape that resembles a vault in cross-section. The circular flange 111 has a narrow first part 117 of the vault, which is formed on the body 111, while the crest 118 of the flange, which forms a support for the cover 112, is surrounded by an adjacent second, wider section 119 of the vault. The second wider section 119 of the vault has a flat part 121 of the surface, which is adjacent to the ridge 118 and is separated from the lower section 124 of the free flange by means of a groove 122 directed towards the body 111. In the transition zone to the section 124 of the free i) flange, the groove 122 is deeper than in the transition zone to the flat part 121 of the surface. This configuration provides a support surface for the lid rim, which will be described below, on the portion of the lower inner wall 126 that protrudes beyond the upper inner wall 125. The lid 112 has a planar cover 131 which is equipped in its upper surface area with a circumferential perpendicularly protruding centering rim 132. On the outer circumference of the covering 131 is the circular rim 133 of the lid, which on the inside has an o-shaped configuration corresponding to the circular flange 116 of the bucket, while the lower free face 134 of the flange, being in the closed fixed position, is located on the support surface 126 in such a way that the sections of the outer surface of the circular rim 133 of the lid and the free flange section 124 of the circular flange 116 are concentric with each other. uh-

The circular flange 133 of the lid is also equipped with an internal circumferentially protruding locking shoulder 135, which in the closed locking position of the lid 112 is fixed on the bucket 110 behind the upper inner wall 125, entering the groove 122 of the circular flange 116. Since the lid 112 is thus fixed on the bucket 110 , cannot be lifted from the body 111 of the bucket without the help of some tool, i.e. by hand, for this purpose an auxiliary opening device 113 is provided. The auxiliary opening device 113 is equipped with a petal 136, which is located in the area of the second section 119. the vault and the free flange section of the circular flange 116, sections 119 and 124 of the circular flange 116 are equipped with cutout 137, in which a petal 136 is installed with the possibility of rotation near one of its end sections.

The petal 136 in the cutout 137 is limited at one circular end by the working face 147, and at the other circular end 7 by the Free face 139, while between the faces 147 and 139, one cam face 140 (curvilinear groove, which -I acts as a cam), formed in the circular direction and directed towards the crest 118, located at a certain distance from the crest 118, and the stepped lower edge 141, which in the direction of the working face 147 is located concentrically with the lower face 142 of the circular flange 116, protrudes at the other end. Remaining free, between

Go! the working face 147 of the petal 136 and the front free face 143 of the cutout 137 of the circular flange 116 is a relatively wide gap 148, in which the device 115 is located, which ensures the protection of the primary integrity of the package about the container and indicates the absence of intentional premature opening. c The working face 147 of the petal 136 extends over a significant part of the zone of the circular flange 116 closer to the ridge 18, but is not fixed in the zone of the additional section 119 of the vault. The free face 139 of the petal 136 is located, basically, parallel to the turning face 138 in a separate zone of the section 124 of the free flange and ends in front of the groove 122 and on the outside of the fixed cover 112. The cam face 140, made with a given configuration, determined by the shape of the cam, which will described below, extends in a circle

F) direction along the section 121 of the flat surface, the groove 122 and a separate zone of the section 124 of the free flange. The cutout 137 in the circular flange 116 has a free rotating face 143, which is parallel to the working face 138 of the petal 136 and, being at a distance from the face 143, a free face 144, the zone of which, located on the section 124 of the free flange, runs parallel to the free face 139 petal 136. There is a narrow gap between the two faces 144 and 139 mentioned above. The cutout 137 in the circular flange 116 can be rectangular in shape. However, in the illustrated third embodiment of the invention, the longitudinal face 146 of the cutout 137, which connects the faces 143 and 144, is located parallel to the cam face 140 of the petal 136.

The curvilinear cam face 140 of the petal 136 has the configuration of a polygon, as a result of which 65 The horizontal section extending from the ledge of the working face 147 is surrounded by a linearly descending section, while the horizontal section, in turn, adjoins the free face 139 in the same way. in the given example of the implementation of the invention, the cam face 140, which can also extend sinusoidally, is only partially covered by the circular rim 133 of the cover, that is, approximately one-third of its end is visible in the area 124 of the free flange.

According, in particular, to Fig. 9, the petal 136 has the possibility of rotation on the pivot axis, which is made in the form of a thin-layer hinge 145, parallel to the free faces 139 and 143 of the circular flange 116 and the petal 136 and located in the plane between the circular surface of the petal 136 and the circular surface body 110 buckets. In this case, a mounting support 160 is provided, formed on the periphery of the body 111 of the bucket, which is made in the form of legs 161 and 162, converging with each other to form a trapezoidal configuration at 7/0 View from below and extending along the entire height of the circular flange 116. Thin-layer hinge 145 is provided in the zone of fusion of two legs 161 and 162. The inner surface of the petal 136 is equipped with a support 163, which resembles a triangle when viewed from below and which is formed by legs 164, 165, converging with each other to form a triangular configuration, and the legs are formed on the petal 136, and one of them, namely foot 165, is made with a relatively longer length. This reinforcing section 163 is attached in the area of the face on which the 7/5 coordination of the connecting legs 164 and 165 takes place, and which extends along the entire height of the petal 136 in the direction of the thin layer hinge 145. Being turned away from the free face 139 of the petal 136 , the connection of the mounting support 160 and the reinforcing section 133 with the help of a thin-layer hinge 145 is carried out in such a way that the working face 147 extends beyond the circular plane of the thin-layer hinge 145, so that the petal 137 has the shortest possible operating lever 147 and the longest possible gripping lever up to and including the free face 139. In the area of the gripping area 150 facing the free face 139, the petal 136 is supported on the inner surface by a short support foot 166", which extends from the periphery of the body 111 of the bucket and is formed on it in such a way that the petal 136 is located in a plane passing around the circumference circular flange 116 in the initial position.

The functioning of the petal 136 as a device 113, contributing to the process of opening the cover, occurs in such a way that the petal 136 is captured in the area of its free circular end, for example, on the gripping area 150 of the petal, which is increased in width or lies under the lower face 142 of the flange 116, and turns around i) the vertical pivot axis 145 outwards, that is, away from the body 111 of the bucket. During this rotary movement of the cam face 147 outwards, the lower face 134 of the cover 112 is captured in such a way that during the subsequent rotary movement of the petal 136, the cover 112 is moved outwards, moved outwards and as it rises, with the Cam face 147, opens and rises (Fig. 12 ). As soon as the cover 112 rises with the help of the device 113, facilitating the opening process, in the area of the flap 136 there is an opportunity when the flap is open to put your hand under the cover 112 in the area of the lower face 134 and pull the cover. Thanks to the thin-layer hinge 145, the petal 136 moves back to its original position, so that, for example, after using the contents of the bucket 110, the lid 112 can be fixed on the bucket again. co

The device 115 mentioned above, which ensures the protection of the primary integrity of the container packaging and indicates the absence of intentional premature opening of it, is movably connected to the device 113, facilitating the opening of the lid 112, made in the form of a petal 136 and located on the body 111 of the bucket 110, after how it will take the position corresponding to the fixed state of the lid, indicates whether the device 113, contributing to the opening of the lid 112 of the body 111 of the bucket, has been activated at least once. "

In the third example of the implementation of the invention, this device 115, which provides protection of the primary integrity of the packaging of the container and indicates the absence of intentional premature opening of it, is formed by a rotary locking loop or clamp 116, placed in the gap 148 between the face 143 of the circular flange;" 116 and the front working face 147 of the petal 136. The locking clamp 170, which extends along the entire height of the free flange section 124 of the circular flange 116, has a T-shaped configuration or a hammer configuration when viewed from below. Thus, the fixing clip 170 has a base (main) foot 171, the free end of which is connected to a stationary mounting foot 176 by means of a rotary axis in the form of a thin-layer hinge 165, and the mounting foot 176 extends from the mounting support 160 in the direction along the circumference of the bucket . Thus, both pivot axes 145 and 175 are located so that o extend parallel in a plane passing approximately along one circle. Being at some distance from the thin-layer hinge 175, the base foot 175 is covered with two interconnected branches 172 o and 173 of the clamp, which in plan form a curved line. Branch 172 of the clamp, directed towards the working face c 147 of the petal 136, is relatively short, while branch 173 of the clamp, directed towards the circular flange, is relatively long, compared to the above. The length of the two branches 172 and 173 in the direction along the circumference is less than the inner width of the gap 148. Along the outer circumference, the branches 172 and 173 are equipped with two fixing faces 174, which extend in the direction of the faces 143 and 147. The height of the base leg 171 of the rotary locking clamp 170 is such that in as a result of the rotary movement of the clamp 170 in the direction of the arrow K, it is free

F) the face of the longer branch 173 penetrates under the free face 143 of the cutout 137 or the circular flange 116. The circular flange 116 is equipped along its entire circumference with the above-described support legs 166 equidistant from each other, among which the leg 166, directed towards the clamp 170, is equipped on its surface, in the direction of the clamp 170, with two parallel similar faces 177, which, when the position of the petal 136, shown in Fig.11 is turned, ensure the fixed retention of the clamp 170 in the specified position.

The operation of the device 115, which ensures the protection of the primary integrity of the container packaging and indicates the absence of intentional premature opening of it, is shown with the help of references to the corresponding locations of the flap 136 and the locking clip 117 in Fig. 10 and 11. When the flap 136 moves 65 From the open position to the closed position , Fig. 9, in the direction of arrow 5, the working face 147 of the petal 136, as shown in

Fig. 10, engages the fixing clamp 170 first in the area of the short branch 172, and then in the area of the front surface of the main leg 171, after which it moves the clamp 170, turning it in the direction of arrow K under the circular flange 116 towards the adjacent support leg 166. rotation of the petal 136, which initiates the lifting of the cover 112, the locking clip 170 with the help of its locking faces 174 begins to interact with similar locking faces 177 on the support foot 166. The locking clip 170 remains in the same locked position when rotated to an angle in the range of 452 to 902 even if the petal 136 moves back from the position shown in Fig. 11 in the direction of arrow M to its original position shown in Fig. 9, or automatically moves back due to the elasticity of the thin layer hinge 145, while the return position, which is possible only near the starting point

7/0 position, the lid 112 can be re-installed in a position in which locking can be provided and locked in this position by means of the flap 136. The fact of the initial opening of the container can be established by the presence of the locking position of the clip 170.
