Description

The present invention relates to a lid for a container with a guarantee seal, i.e. the lid is provided with a seal, which after the first opening is destroyed, thus being an indication of the fact that the container has been opened or tampered with.

Warranty seal lids are known to have become widespread because they allow the consumer to ensure that the container has not previously been opened or tampered with. Such a guarantee is of particular value when it comes to containers for food pastes or liquids, such as fruit juices, in which opening the container may cause deterioration of the contents or, in some cases, the introduction of unwanted substances into the container.

Fruit juice containers, in particular, are commonly used by children, so many more or less stringent country-specific standards prescribe some safety requirements that lids must meet.

Standards usually impose some restrictions on the size of the lid in order to prevent them from being swallowed by children.

With currently known lids, when the lid is unscrewed, the warranty seal breaks into a plurality of pieces which remain attached to the lid body, so that such pieces are substantially prevented from being swallowed by children.

However, in addition to being loosely connected to the lid body, such parts form sharp protrusions that protrude dangerously from the lid body. Sharp protrusions can harm a child's eyes, or they can be separated from the lid body by teeth and swallowed.

The closest analogue is the lid (RU2420441, publ.: 06/10/2011) connected to the connecting part of the container and disconnected by rotation around the axis of rotation from the said connecting part, in which the connecting part contains durable elements that engage with the lid; and wherein said lid contains:

- an element for gripping by hand, suitable for rotation by the user to detach the lid from the container;

a warranty seal integrally formed with the hand-grip element and containing a plurality of warranty sections, the seal being torn when the seal is broken;

at the same time, at least one of the guaranteed sections contains:

- an engagement section comprising at least one engagement element for engagement with the strong elements of the connecting part to prevent rotation of the warranty seal;

- a connecting section connected to the engaging section, containing at least one connecting element, which ensures the connection of the connecting section into one with the element for gripping by hand;

and wherein the warranty seal comprises at least one bridge that connects adjacent warranty areas to each other, the bridge being destructible by rotating the hand grip member relative to the warranty seal;

and the guarantee seal further comprises a safety element that provides connection of the engagement area with the element for gripping by hand, and the safety element is structurally configured to keep the engagement area limited in the configuration of the broken seal.

In the prototype, a guarantee seal is provided which will be particularly safe to use even by children.

The technical problem of the solution according to the prototype is the poor operation of the locks (in the real version, the lid locks are not always and not all destroyed).

In addition, when opening, there is a slight change in appearance (not obvious for visual control of the first opening), and when the lid is closed again, the locks return to their original position and it is almost impossible for the user to see a gap in the control ring.

Also, when the bridges are destroyed, a part of the bridge can be torn off, which can get into the product, all the more it is unacceptable when using covers of this type for capping baby food.

The objective of the invention is to eliminate these technical problems inherent in the prototype.

The technical result of the invention is the expansion of the arsenal of technical means of covers with a guarantee seal. In addition, reliable operation of locks is ensured; when opening, there is a clear change in appearance, and when the lid is closed again, the locks no longer return to their original position and the control gap is always observed explicitly; the detachment of a part of the jumper, which can get into the product, is excluded.

The specified technical result is achieved due to the fact that the lid is claimed to be connected to the connecting part of the container and detached by rotation around the axis of rotation from the said connecting part, in which the connecting part contains durable elements that engage with the lid; and while said cover contains a warranty seal, made integral with the cover and containing the warranty areas, and the seal contains gaps when the seal is destroyed; wherein each of the warranty sections contains a section of engagement with the element for engagement with the strong elements of the connecting part to prevent rotation of the warranty seal; characterized in that the guarantee seal is a lock, which consists of a lower control part for engagement with the rib of the connecting part of the container and an upper fixing part, wherein the lower and upper fixing parts of the lock are made as a single unit, and the lock is connected through a line of weakened section with a reinforced rib , and the length of the upper fixing part of the lock is greater than the radial distance from the line of the weakened section to the outer annular surface of the middle part of the lid, and the upper fixing part of the lock is made with the ability to rotate until it stops against the outer annular surface of the middle part of the lid, and then rotate the connecting part of the container, while the end of the reinforced rib has the ability to be elastically deformed for radial displacement of the weakened line from the outer annular surface of the middle part of the cover, and when the locking part of the lock is located at the end of the rotation relative to the line of the weakened section, which is located in the original position, the control part of the lock closes the line of sight to the outer annular surface of the connecting part of the container, and is made with the ability to rotate simultaneously with the upper fixing part, and open a window with a view of the outer surface of the connecting part of the container, and at the end of the turn be located outside the field of effective action of the rib connecting part of the container.

Preferably, the implementation of the device according to Fig.1.

Preferably, the reinforced rib is connected to the outer annular surface of the middle part of the lid by a stiffening rib.

Preferably, the reinforced rib is connected to the main rib of the cover.

Preferably, the reinforced rib on the side of the weakened rib is of reduced stiffness.

It is preferable that the design of the device is such that the outer surface of the guarantee seal is made in a different color than the outer surface of the connecting part of the container.

It is preferable that the design of the device is such that the outer surface of the connecting part of the container opposite the window is made with a printed symbol. This character can be an exclamation point.

Implementation of the invention

As in the prototype, the lid is connected to the connecting part of the container and is disconnected by rotation around the axis of rotation from the said connecting part, in which the connecting part contains strong elements that engage with the lid.

At the same time, said lid contains a guarantee seal made integrally with the lid and containing guarantee sections, and the seal contains breaks when the seal is destroyed.

Each of the warranty sections includes a section of engagement with an element for engagement with strong elements of the connecting part to prevent rotation of the warranty seal.

The essence and difference of the claimed invention from the prototype is the absence in the claimed device of such an element as a jumper. In the claimed solution, the warranty seal does not contain a jumper that connects adjacent warranty areas to each other.

The guarantee seal is formed by a lock, which (see Fig.1-Fig.8) consists of a lower control part 1 for engagement with a rib 2 of the connecting part of the container and an upper fixing part 3. The lower control 1 and the upper fixing 3 parts of the lock are made as a single unit .

The lock (see Figure 2) is connected through a line of weakened section 4 with a reinforced rib 5 connected to the main rib of the cover 6.

Reinforced rib 5 (see Figure 5) is connected to the outer annular surface 7 of the middle part of the lid by a stiffener 8. The length of the upper locking part 3 of the lock is made greater than the radial distance from the line of the weakened section 4 to the outer annular surface 7 of the middle part of the lid to ensure a guaranteed breakage of the fixing part 3 with a click, and not its usual bend with a return to its original position.

In this case, the reinforced rib 5 can be connected to the outer annular surface 7 of the middle part of the cover with a stiffening rib.

The reinforced rib 5 on the side of the line of the weakened section 4 can be made of less rigidity.

The connecting part of the container can be made in the form of a neck 11 (see the example in Fig.12) with an external thread, on which a cap with an internal thread is screwed. In this case, the rib 2 of the connecting part of the container is located in the upper part of the neck 11 located outside the container.

When opening (see Fig.8), the lid is rotated by the consumer relative to the connecting part of the container soldered to the bag with the product, while the lower control part 1 of the lid lock engages with the rib 2 of the connecting part of the container, the lock rotates relative to the line of the weakened section 4 (see. Fig.9), and the upper locking part 3 of the lock rotates until it stops in the outer annular surface 7 of the middle part of the cover, and then elastically deforms the reinforced rib 5 (see Fig.8), so that the locking part 3 of the lock can pass between the reinforced rib 5 and an annular surface 7 of the middle part of the cover. When passing the critical point, the lock rotates to the final position (see Fig.10), and the reinforced rib 5 takes its original position.

At the same time, when the fixing part 3 of the lock of the critical point passes, a dull click occurs, which also informs the buyer about the first opening of the package.

In the final position of the lock (see Fig.10), the lower control part 1 of the lock is pressed against the surface of the reinforced rib 5, and leaves the zone of effective action of the rib 2 of the connecting part of the container, after which the lock no longer returns to its original position when the lid is screwed on again. connecting part of the container.

Thus, the lock is fixed in the open position and forms a visible window 10 in the control tape for visual control of the first opening of the package.
In the initial position, to limit the mobility of the lock relative to the reinforced rib 5 along the line of the weakened section 4, the lock and the reinforced rib 5 can be connected by an indicator rib 9.

When the lock is turned, the indicator rib 9 is plastically deformed and, along with the locking part 3 of the lock, also prevents the lock from returning to its original position.
When using plastics that change their color during plastic deformation (for example, turn white), the indicator rib 9 and the line of weakened section 4 will also signal the first opening of the container.

The implementation of the warranty seal of the lid in a different color than the connecting part of the container will enhance the effect of the perception of opening the container.

Also, the outer surface of the connecting part of the container opposite the control part of the lock can be made with a printed symbol, for example, an exclamation mark.

Therefore, the operation of the device as described above shows that the upper locking part of the lock is made with the ability to turn all the way into the outer annular surface 7 of the middle part of the lid, and then turn by the rib 2 of the connecting part of the container, while the end of the reinforced rib has the ability to elastically deform for radial displacement weakened line from the outer annular surface of the middle part of the cover.

When the fixing part of the lock is located in the initial position, the indicator part of the lock closes the line of sight to the outer surface of the connecting part of the container, and is made with the ability to rotate simultaneously with the upper fixing part 3, and open the window 10 with a view of the outer surface of the connecting part of the container, and at the end turn to be located outside the field of effective action of the rib of the connecting part of the container.

The above-described method of opening the lid according to the invention ensures that the locks are securely actuated with the formation of a visible window 10 in the control tape, and this control gap is always clearly visible.

And due to the exclusion from the design of the jumper, available in the prototype, the separation of that part of it that can get into the product is excluded.
