Description

The invention relates to devices that prevent re-filling of containers, namely, caps for bottles and similar products, preventing the replacement of valuable liquid with a fake with misleading the buyer-consumer.

The typical design of the safety cover in the main elements is unified and known by the patents of the Russian Federation 2129512, 2150417, 2161585.

The closest analogue (prototype) of the proposed safety cover is the device according to the patent of the Russian Federation 2161585 / IPC ⁷ B 65 D 41/38, Bull. 1, 10.01.2001 /.

This device contains:

- a prefabricated filling element, consisting of hermetically connected pouring and landing parts with a tight fit in the opening of the neck of the bottle and the shut-off valve inside and between them,

- a cylindrical sleeve,

- a cap consisting of an inner cap and an outer cap worn on the inside and having a loose connection from below with an indicator ring tape with several transverse cuts uniformly around the circumference.

Internal teeth were made on the tape, and opposite (with the same angular pitch, but with offset) external teeth were made on the sleeve to enter into mutual engagement during the first unscrewing of the cap and the subsequent detachment of the tape from the outer cap.

The inner cap is attached to the sleeve by means of a loose connection to detach them from each other during the first unscrewing of the cap.

Between the inner cap and the filling element there is a threaded connection for unscrewing and screwing the cap.

The sleeve has an internal gear protrusion for holding the filler element by its opposite gear bottom flange and connecting means for rigid axial and rotational fixations on the outside of the neck of the bottle.

Between the caps, a spline connection is implemented to keep them from mutual rotation.

The known lid has a number of significant design flaws, due to which unauthorized access to valuable liquid of the bottle and its subsequent replacement with a fake are possible without the appearance of noticeable signs of performing these operations in the appearance of the lid and bottle.

Including this can be done through the following actions:

- power removal (with a fairly easy overcoming of the effort of fixing the annular belts of the caps latched on top of each other) from the inner cap strictly in the axial direction of the upper cap with the indicator ring tape without any destruction;

- subsequent unscrewing of the inner cap with a break in the weakened connection with the sleeve;

- free access to the filling element of the lid;

- and then, after replacing the contents of the bottle, the assembly steps are reversed so that the lid assumes almost the same initial position without disturbing its appearance (the broken connection of the inner cap with the sleeve is always hidden from the customer’s view from the outside by a stored indicator tape), entering misleading buyer.

This operation is greatly facilitated by heating the lid, for example, by lowering it with a bottle in hot water.

The task that forms the basis of the present invention is to create a safety cover of the specified type, which has such structural and functional characteristics in order to eliminate primarily the aforementioned disadvantage of the prototype, namely, to ensure reliable one-piece engagement of the caps with each other, which is practically not affected by unauthorized power and temperature effects.

The problem is solved by the fact that the proposed cover further comprises a lock ring-shaped liner, which is latched between the caps due to the ribs on one side, which fit into the slots of the inner cap corresponding to the angular step and abut against its bottom, and on the other hand, due to the stop its sharp bottom edge of the butt in the flange located above the splines of the outer cap. The liner is made of hard material, such as polycarbonate.

It is important to note that this problem is solved by a fairly simple and cheap additional structural element. Along the way, this solution makes it possible to significantly simplify and reduce the cost of manufacturing technology for another element of a typical design - the inner cap due to the fact that it no longer requires the manufacture of ring belts by introducing several movable elements into the injection mold. These belts in the proposed device are functionally replaced by technologically much simpler and cheaper to manufacture slots and a lock ring-shaped insert.

Other features and advantages of the safety cover in accordance with the present invention will become apparent from the following description of its specific implementation.

In particular, in continuation of the topic of unauthorized access to valuable liquid in a bottle for the purpose of replacing it, it is also possible in the prototype device to unauthorized removal of not only a part, but also the entire lid after heating, acting by a continuous extruding upward force on the lid sleeve from its sides in the axial direction.

Then, in order to eliminate this possibility, the safety cover, in addition to the proposed insert between the caps, may additionally contain in the bushing another ring-shaped insert also of rigid material, for example polycarbonate. The liner should be tightly inserted into the sleeve with support from below on its inner flange and have annular protrusions covering the lower flange of the filling element from above and the upper flange of the bottle from below, respectively.

The description contains links to the drawings, on which are presented:

figure 1 - the sequence of assembly of the elements of the safety cover in a single unit,

figure 2 - combined axial section and side view of the cover assembly.

The safety cap shown in the drawings is intended for a bottle, in particular for high-quality alcoholic beverages.

The cap on the bottle 1 includes a prefabricated filling element 2, which consists of hermetically connected pouring 3 and landing 4 parts with a tight fit in the opening of the neck of the bottle 1 and the shut-off valve 5 inside and between them, which serves to prevent the bottle 1 from being refilled, cylindrical sleeve 6, cap consisting of an inner cap 7 and an outer cap 8, worn on the inside and having a loosened connection 9 from the bottom with an indicator ring tape 10. On the tape 10, the inner teeth 11 are made, and on the sleeve 6 - counter external teeth 12 (with the same angular pitch, but with offset) for their mutual engagement during the first unscrewing of the cap and the subsequent detachment of the tape 10 from the outer cap 8. The ring tape 10 is divided into two structurally independent identical semicircular elements by two diametrically opposite cross sections. The weakened connection 9 and two cuts are obtained by means of knives after molding in the form as a whole of the outer cap 8 and tape 10.

The inner cap 7 is attached to the sleeve 6 by loosening (to detach from each other during the first unscrewing of the cap) connection 13, which is obtained by the action of the knives after molding in the form as a single unit of the inner cap 7 and the sleeve 6.

Between the inner cap 7 and the casting part 3 of the filling element 2, a threaded connection 14 is made for the possible repeated unscrewing and screwing of the cap during the authorized use of the bottle. The cap has an external knurling for ease of unscrewing / screwing it through the threaded connection 14.

The sleeve 6 has an inner gear protrusion 15 for holding the filler element 2 by its opposite gear bottom flange 16, and connecting means 17 (inner annular protrusion, axial protrusions for engaging with the groove and channels, respectively, made externally on the upper collar and neck of the bottle ) for sufficiently rigid axial and rotational fixations on the outside of the neck of the bottle 1.

Between the caps around the circumference, a spline connection 18 is provided to hold them from mutual rotation. The slots have corresponding pointed ends serving to guide the outer cap 8 to the inner cap 7 in accordance with a given angular pitch during assembly.

The cap further comprises a lock ring-shaped insert 19, which is latched between the caps due to the ribs 20 on one side, which are included in the corresponding in the angular pitch of the slots 21 (18 teeth / slots in the shown embodiment) of the inner cap 7 and abut against its bottom, and after this, on the other hand, due to the stop after snapping with its sharp lower edge of the end face into the collar 22 of the outer cap 8. put on top. The insert 19 is made of rigid polycarbonate material.

The ribs 20 of the liner 19 have pointed inlet tips and are inclined to the center from the bottom up, and the slots 21 provide access to the ribs 20 until they stop in the bottom 22 of the inner cap 7.

The safety cover may further comprise an annular insert (not shown in the drawings) made of rigid polycarbonate material tightly inserted into the sleeve 6 with the lower edge resting on its inner flange and having annular protrusions covering the lower flange 16 of the filling element 2 from above and the upper flange of the bottle from below 1 respectively.

The proposed lid is assembled with all parts as one unit and can be transported separately and is intended, for example, to be mounted on a bottle.

The main advantage of the proposed lid is, in particular, in the guaranteed impossibility without a noticeable and irreversible violation - deformation of the appearance of the lid of unauthorized access to the contents of the bottle in order to replace it.

In the safety cap in accordance with the present invention, any unauthorized filling of the bottle is excluded, even if means such as prolonged heating of the cap and bottle are used. Such protection takes place thanks to one or two additional inserts made of relatively rigid material, for example, polycarbonate (unlike other parts of the lid, mainly made of relatively softer deformable material, for example, polyethylene) and withstands, as has been practically proved, continuous heating .

Another advantage of the lid in accordance with the present invention is the ease and low cost of manufacture and quick assembly. The main objective of the invention is solved by a fairly simple and cheap additional structural element, which also allows you to significantly reduce the cost of the manufacture of another element of a typical design - the inner cap, which is very important for the product if it is necessary for mass production.
