B of Fig. 3, pos. A-D of Fig. 8), 40 - the visible part of the space inside the can after opening the lid segment 15 banks (Fig.6, pos. A Fig.9).

When using a key, the following functional components are important.

Button 3 is used for mechanical impact - the application of force F to the key when opening / closing the can by pressing it. The force vector is shown by this symbol.

The plug 7 of the key 1 serves to close the jar lid that has been opened up to this segment 15. The key plug is formed by the walls 23 and the bottom 24 (figure 3). The conical shape of the cork 25 enables a smoother setting and removal of the cork from the lock 14.

The bandage or seal 12 of the plug is intended to improve sealing between the plug and the open edges of the cap segment when the key closes the cap. Element 12 is applied to the flange of the plug 30 along the upper perimeter of the plug in the place where it touches the lid, or element 12 covers the entire surface of the plug in its lower part. Element 12 is made of flexible and sufficiently durable synthetic or rubber-plastic material, which has permission to use in contact with food liquids.

Lock 14 plugs is designed to lock the plug in the closed position. The lock is located on the rear wall 13 of the plug 7, it can have various shapes (pos. A, B, C, D, D of Fig. 8).

(figure 3), but always in the form of a convex profile from the outside. Due to the convex shape of the lock of the cork with respect to the edge 28 of the cover (pos. A of Fig. 5), the cork is fixed in the closed position. In this case, only the edge of the lid prevents the lock from exiting from the closed position. The lock can be made either by stamping on the contact rear element 13 of the cork, or by obtaining a similar stamping profile made of the material of the element 12 deposited on the cork.

The cut key segment 10 (FIGS. 1, 2) is located at some distance from the key hole 16 (FIGS. 2, 3). The segment provides a mechanical connection of the key with the axis of the cap and makes it possible to raise and lower the key in a vertical plane, leaning through it on the axis 9 of the cap (figure 1). With its help, a support point of the lever is formed, which is the key, which acts through its contact element 8 on the open sector 15 of the cover.

The hole 16 in the key (figure 2, 3) under the axis of the lid is intended for fastening through the axis 9 of the key 1 to the lid of the can 2 (figure 1). When they are connected, a key support point is provided through segment 10 with a can. The connection of the key with the axis is ensured by the nozzle of the key on the axis with subsequent mechanical action on the upper part of the axis to unfasten it. This ensures sufficient rigidity of their joints in the vertical plane with the possibility of free movement of the key in the horizontal plane.

The contact front element 8 of the key (FIGS. 1, 2, 3) is intended for mechanical impact on the open sector 15 of the lid as a small shoulder of the lever formed by the key and the axis 9 of the lid of the can, performing the fulcrum of the lever (FIGS. 4, 5). The contact shape of the key 8 can be changed depending on the shape of the opening segment of the lid or the pattern of the notch bounding segment 4 (Fig. 1).

Curved elements 19 of the key (figure 2, 3) are used to give greater strength to the key along its edges. These elements can be obtained by stamping in the manufacture of the key.

The contact rear element (wall) 13 of the plug (FIG. 3) is that part of the plug wall on which the lock 14 is located, fixing the key plug in the closed position (pos. A of FIG. 5).

The through segment 20 on the key button (figure 2, 3) provides a more reliable contact with the button 3 when exposed to it. In addition, the through element improves the strength properties of the key button due to the fact that its edges are bent around its perimeter.

The inner cavity 22 of the tube is formed by the walls 23 and the bottom 24, has a conical shape 25 (position A and section AA of FIG. 3), decreasing from top to bottom.

The walls of the cavity 23 of the tube (figure 2, 3) form the vertical walls of the tube. The shape of the wall coming into contact with the bulge 33 should provide minimal resistance to sliding, especially at the initial moment of their contact.

The bottom of the cavity 24 of the cork is the lower flat part of the cork, when closing the cork, it goes inside the open segment of the can lid, closing the open segment 15, and is also a contact element of the key when interacting with the bulge 33 (pos. 4).

The gap 26 between the button of the key 3 and the rim 11 of the lid of the can is necessary for the possibility of displacement of the plug 7 when the lid is opened with the button (pos. A of Fig. 5). The gap is determined by the interaction of the button and the rim of the cover and can be equal to 1-2 mm.

The gap 27 between the lock 14 of the cork and the edge 28 of the cut-off lid of the can (pos. B of FIG. 5) is formed after the force F is applied to the button 3 of the key to remove the cork from the lock and the possibility to open the can segment.

The edge 28 of the can lid (pos. B, D of FIG. 4, pos. A, B of FIG. 5) is a part of the can lid formed after cutting off its segment 15.

The flange of the plug 30 (figure 2, 3) is the upper flat part of the plug, which overlaps along the perimeter of the line of articulation of the plug and the cut off segment of the lid after it is closed.

The gap 39 in the plug 7 (pos. B of FIG. 3) is necessary so that the edge of the lid of the can 28 fits into it when it is closed.

The lid 5 of the can has the following elements located on it (figure 1).

The axis 9 of the lid of the can (Fig.1, 4, 5) performs the function of the power element of the lid. It is made in such a way that it is an integral part, made during stamping of the cover. On the axis is attached a key 1 (figure 2), which can be moved both in the vertical and horizontal plane. When moving the key in a vertical plane, the axis is for him a fulcrum as an acting lever.

The bounding segment of the notch 4 (FIG. 1), applied to the surface of the lid, shows the contour along which, under the influence of the key, the lid opens.

The opening segment 15 of the lid (Figs. 1, 4, 5) is a part of it that opens under the influence of a key.

Profile recess 17 (Figs. 4, 6, 7) - the key is initially located in it before opening the lid. It reduces the chance of accidentally moving the key in the horizontal plane.

Graphic symbol 18 (figures 1, 6, 7) on the lid can be made with a coloring substance or a notch. It is applied to indicate the direction of movement of the key to open the can and close it.

The unopened sector 6 of the can segment (FIG. 1, position B of FIG. 4, position A, B of FIG. 5) is part of a lid segment that, after opening, remains uncut with a key due to the absence of a notch on it and which holds the cut part of the segment lids inside the can.

Rubber-plastic (synthetic) coating 21 (figure 4, 5) is intended to cover the lid of the banks from the inside. This coating can perform two functions:

- when the opening segment 15 has a continuous upper notch on the lid of the can and does not have a sector 6 of the lid segment, and when opened, it is completely disconnected from the metal part of the lid, but segment 15 continues to be held on it inside the can due to the undisturbed part of the specified coating;

- a fragmented or complete coating of the inner surface of the lid of the can with said material can replace the need to use sealant in the joint 29 of the lid 5 and the can 2 (FIGS. 4, 5);

- profile bulge 33 (Fig. 1, pos. B of Fig. 4, pos. B of Fig. 9) on the lid of the can — a convex segment designed to lift the key plug 7 upward by the force generated by the contact interaction of the bottom 24 of the plug from sliding along the bulge when the key is moved in the horizontal plane (pos. 4) according to the graphic direction 18 for the key to move. The shape of the bulge 33 may be different, the goal is to minimize the sliding resistance of the tube on its surface. For example, it can be made in the form of 2-3 radial bulges (Fig. 7, pos. A of Fig. 9), but its dimensions in height and length should ensure the opening of the lid segment 15 along the notch line 4 with the key element 8. And also provide cork 7 guaranteed exit from the cut segment to a minimum of 1-1.5 mm approach element key 8 to the cut part 28 of the cover.

The bulge may have on each contact side (pos. 36, 37 of Fig. 1, pos. B of Fig. 9) various angles formed with the plane of the lid of the can. At the beginning of the interaction with the cork, it has a more sloping shape (a smaller angle 34), at the end of the interaction with the key a steeper shape (a larger angle 35 - pos. B of Fig. 9). This shape of the bulge provides for the key element 8 optimal, i.e. smooth entry into sector 15 at the beginning of the movement and vigorous exit from the sector after the interaction of the bulge 33 and the bottom of the plug 24 has ceased.

The radial distance 38 from the axis of the cover 9 to the surface of the bulge should provide free passage when moving the front element 8 of the key (pos. In figure 4).

The key is used as follows.

In the initial position, the key is in sector 17 of the lid of the can, having a small recess. To open the can, it is necessary to act on the button 3 of the key with the force F, so that the vector is directed in the horizontal plane (pos. B, C of Fig. 4) according to symbol 18 on the lid of the can (Figs. 1, 6, 7). When the key 1 moves in a horizontal plane, it leaves the sector 17 and, moving along the surface of the lid of the can 5, approaches the bulge 33 (Figs. 1, 4, 9). Due to the interaction of the contacting surfaces of the bottom 24 when sliding (pos. 4), the key plug 7 and the bulge 33 on the lid of the can, the key plug moves up and, accordingly, moves down its contact element 8, which acts by force F (pos. B 4) on the opening segment 15 of the lid of the can.

With further horizontal movement of the cork along the convex surface, a slice of the opening segment 15 is provided along the notch line 4 (Fig. 1, pos. 4) from the action of the key element 8 on it, with the exception of a small non-cutting part 6 of the segment 15 (Fig. 1, pos. In figure 4, figure 6).

After the bottom 24 of the plug passes the contact surface of the bulge 33, the plug of the key with its bottom 24 is lowered onto the surface of the lid 5 of the can and, accordingly, the front contact element 8 of the key rises and leaves the open segment 15 of the lid. It stops with a slight excess (1-1.5 mm) in height to the upper plane of the lid of the can (pos. G figure 4). Exceeding is necessary for further unimpeded movement of the key in the horizontal plane. The open segment of the lid goes inside the can, but remains attached to the lid due to its uncut part 6 (Fig. 1, pos. B of Fig. 4, pos. A, B of Fig. 5). If the lid of the can and the opening segment from the inside is covered with a rubber-plastic (synthetic) coating, then, if there is a corresponding notch, a complete cut of the metal part of the segment is allowed, but the segment remains attached to the inner side of the can lid due to the uncut part of the specified inner coating. In this case, the metal edge of the completely cut off segment of the lid will be even along its entire perimeter, which will significantly improve the tightness after closing it with a stopper.

Thus, when the opening segment of the lid fully enters the can, the lid is considered open.

To close the jar, i.e. open to this segment, first you need the influence of the force F on the key button, acting in the horizontal plane in the direction indicated by arrow 18 on the lid of the can (Fig. 1, 6, 7, 9). The key is moved until it is compatible with the open sector 15 of the lid 5. After combining them to close the cans, press the button 3 (pos. A of Fig. 5) in a vertical plane from top to bottom with respect to the base of the can. The key plug 7 when moving down reaches the position when its lock 14 goes under the edge 28 of the segment of the lid of the can (pos. A of Fig. 5).

The key plug locks, as its exit from the segment is impossible due to counteraction to the lock of the specified edge. The can lid is then considered to be closed with a key 1 (pos. A of Fig. 5, Fig. 7).

To open the can lid sector closed by the key plug, it is necessary to apply a force F (pos. B of Fig. 5) acting on the key button 3 at an angle of 40-60 ° to the horizontal plane in the direction to the center of the can or axis 9 of the lid. In this case, due to the gap 26 (pos. A of Fig. 5) between the key button and the rim 11 of the lid, the key plug moves to the center of the can, sufficient to exit the lock 14 of the plug from its articulation with the edge 28 of the can cover (pos. B of Fig. 5 ) Upon further lifting the key, the plug completely out of contact with the cap (pos. In figure 5).

Further movement of the key in the horizontal direction makes the segment completely open (pos. 5, 6).
