CAPPING DEVICE with belt OPENING INDICATIONS

The present utility model relates to a closure device with a tamper-evident element that detaches from the closure device at the first opening.

Devices of this type have long been well known. Closest to the proposed utility model in its design is the "safety shutter company Guala, see patent of the Russian Federation 2161585, class. B65D 41/38, 1995. A well-known capping device contains five main parts - a body with a skirt in its lower part for fixing on the neck of the bottle and passing in its upper part into the inner cap with thread on its inner surface; a pouring element with a thread cooperating with the thread on the inner surface of the inner cap located in the housing and usually provided with a one-way valve element; and outer cap. The inner and outer caps are equipped with means for fixing each other. The tamper indicating belt is located along the lower edge of the outer cap and is connected to it by several fragile bridges. Teeth for interactions are made on the inner surface of the girdle.

actions with the corresponding teeth on the case and thus preventing the tamper of the tamper indicating indicator from turning relative to the case.

When assembling a known closure device (“safety shutter”), the outer cap is fixed on the inner cap, which is a continuation of the housing, so that both caps form a single part - a threaded lid, rigidly fixed to the housing.

After installing the outer cap on the capping device, the teeth of the tamper-evident belt interact with the teeth on the body, so that the belt cannot be rotated relative to the body. When opening the capping device for the first time, turning the threaded cover destroys the brittle bridges of the tamper-evident belt, and the belt separates from the capping device, allowing the lid to be completely unscrewed.

The design of the known closure device, however, has at least two obvious disadvantages. Firstly, during the assembly process, difficulties arise with fixing the pouring element inside the housing, which may warp or hang. Secondly, when installing the outer cap, it slides with force the inner surface along the outer surface of the inner cap until the means of fixing the caps come into interaction. Such locking means are typically horizontal annular grooves on one cap and horizontal annular protrusions on the other cap. It is understood that the presence of protrusions increases friction and accordingly increases the installation force of the outer cap. Therefore, with this design of the closure assembly during installation of the outer cap, damage to the fragile bridges of the tamper evident belt is possible.

The proposed utility model eliminates the aforementioned problem by the fact that the tamper-evident strip is connected by fragile bridges not to the outer but to the inner cap, and the inner cap is not a continuation of the case.

With this embodiment, the tamper evident belt provides the following advantages:

1) - since the outer cap, which is mounted on the inner cap with force, now does not have a tamper evident belt, the installation of the outer cap can now be simplified, and the probability of occurrence of defective products in this operation is minimized due to the fact that the belt during this operation does not experience impacts that could cause damage to fragile bridges or separation of the girdle;

2) - due to the fact that the inner cap is not a continuation of the casing, it can be molded from plastic of a different color than the color of the casing and the outer cap, which will provide color highlighting of the tamper-evident belt. Preferably, the diameter of the tear strip is larger than the diameter of the inner cap. Even more preferable.

the diameter of the girdle corresponds to the diameter of the outer cap, and the diameter of the outer cap corresponds to the diameter of the body skirt. This will make it possible to obtain a closure device having a generally cylindrical external shape, since both the girdle and the body skirt will be aligned with the outer surface of the outer cap.

3) - Simplified design and mounting technology of the pouring element to the housing. The fastening of the pouring element to the housing is now ensured by the interaction of the annular protrusion on the housing and the annular groove on the pouring element.

Further, the proposed utility model is illustrated by a preferred example of its implementation with reference to the accompanying drawings, in which:

FIG. 1 is a schematic sectional view of a closure device according to the invention, and

FIG. 2 is an enlarged view, partially in cross section, of an outer cap (top) and an inner cap (bottom), according to a preferred embodiment.

In FIG. 1 shows a closure device comprising a body 1 having an elongated skirt in the lower part mounted on the neck of a traditional (glass) bottle (not shown).

Inside the housing 1 there is a pouring element 2 provided with a thread 3 for a threaded cover formed by an inner cap 4 with a thread 5 on its inner surface interacting with a thread 3 on the pouring element 2 and an outer cap 6. The outer and inner caps are fixed relative to each other with by means of mutual fixation (which is better seen in Fig. 2), moreover, the means of mutual fixation of the inner and outer caps in the shown embodiment serve as annular grooves 7 on the inner cap 4 and the corresponding protrusions upy 8 on the inner surface of the outer cap 6, interacting with the said grooves.

On the inner cap 4 there is a belt 9 for tamper indication. The girdle 9 has (only partially shown) fragile bridges 10 connecting it to the lower part of the inner cap 4. The girdle 9 has a diameter greater than the diameter of the inner cap 4, and preferably corresponds to the diameter of the outer cap b, so that after the said caps are mutually fixed, a threaded cap is formed will have a generally cylindrical outer shape. To facilitate handling of the threaded cover, vertical notches 11 are preferably provided on the outer surface of the outer cap b.

Otherwise, the design of the caps described above is similar to the design of the caps of the known closure device, therefore, a more detailed description of the caps is not given below.

The pouring element 2 typically comprises a single-code valve element 12. The purpose of the valve element 12 is to allow liquid to be poured out of the bottle, but preJL l J.nbJL04 5

commemorate its re-filling. The design of the pouring element 2 is generally similar to the designs of the pouring elements used in known closures, however, it has one feature, namely, an annular groove 13 designed to interact with the annular protrusion 14 on the housing for rigidly securing the pouring element 2 in the housing 1.

When assembling the proposed closure device, after the pouring element 2 with the valve element 12 is placed inside the housing 1, and the inner cap 4 is screwed onto the upper part of the housing 1, the outer cap b is installed, which is pressed onto the inner cap 4 until engagement of the protrusions 8 on the inner surface of the outer cap b in the grooves 7 on the outer surface of the inner cap 4. At the same time, the tamper-evident strip does not experience stresses that can destroy brittle bridges lancing band with inner cap. After this operation, the caps are fixed together and form a single threaded cap, since when turning the outer cap b, it will rotate the inner cap 4. The finished closure assembly is mounted on the neck of the bottle and fixed on it in the traditional way, for example, using the annular inner protrusion 15 on a skirt catching an annular tide on the (not shown) neck of the bottle. 6

Due to the fact that the girdle 9 is held relative to the body, as explained in the introduction, and the body is held on the bottle neck by the protrusion 15, the first unscrewing of the threaded cap will break the brittle bridges 10 and separate the tamper-evident belt 9 from the inner cap.

It is clear that the above embodiment is not limited; he proposes a utility model in which various modifications will be apparent to the skilled person without departing from the scope of the attached utility model formula. 1
