Abstract

The present invention disclosures a bottle closure comprising an outer cap (3) having the element (11) of reduced hardiness for displaying an opened state, closing device (2) to be fixed in the bottle neck (14) for pouring the liquid, by means of movable thread connection (7, 8). The outer cap is made with a rotating possibility in respect of the bottle neck and is connected with the closing device through a movable slip joint. Furthermore, the element of reduced hardiness is located on an external fore face of the cap, and the closing device comprises an external (12) for providing a separating action on the element with reduced rigidity.

Description

BOTTLE CLOSURE

Technical Field The present invention relates to a bottle closure and namely to caps and closures with the places of reduced rigidity for opening the bottles and thus forming the holes for pouring the liquid.

Background Art A known closure for the bottle is composed of an outer cap having the element with reduced rigidity connected with the closing device and the bottle's neck by a thread connection for displaying an opened state (JP No.5004648, B 65 D 41/34, 1993). The mentioned closure can only be used in thread bottles, moreover, in trying to repeatedly fix it to the neck of the bottle it can not ensure a reliable closure of the hole for pouring the liquid. The more elaborated and closer analogue of the present invention is a closure for the bottle composed of the outer cap having the element with reduced rigidity for displaying an opened state, neck for pouring the liquid, made with the possibility to be fixed on the neck of the bottle, and closing device, which is arranged in the neck for pouring the liquid and connected with it by a movable tread connection (RU No.2129512, B 65 D 41/34). However, the above mentioned technical solution is based on slip protrusions on the bottle neck which as a result extremely complicate the technology of production and increase the manufacturing costs of final production. Moreover, breaking of the element of reduced rigidity becomes likely as a result of fixing the said closure on the bottle's neck.

Disclosure of Invention The goal of the present invention is to provide more economic and reliable means for closing the bottle's neck. Technical result, which could be obtained in case of its fulfilment, is reduction of the manufacturing costs and increase of reliability in assembling and also in multiple opening and closing the hole for pouring the liquids. The bottle closure of the present invention is composed of an outer cap having an element of reduced rigidity for displaying an opened state, spout for pouring the liquid made with the possibility to be fixed on the bottle's neck, and closing device connected with the spout for pouring the liquid by means of a thread connection. The outer cap is made with a rotation possibility in respect of the bottle's neck and is connected with the closing device through a movable slip joint. The element of reduced rigidity is located on an external fore face of the outer cap, and the closing device comprises external element for providing a separating action on the element with reduced rigidity.

Brief Description of Drawings The invention will be more fully understood from the detailed description thereof taken in connection with the accompanying drawings wherein: Fig.l is a general sectional view of the assembled bottle closure in a closed state; Fig,2 is a vertical sectional view of the spout for pouring the liquid; Fig.3 is a transversal sectional view of the spout for pouring the liquid from the underneath; Fig.4 is a vertical sectional view of the closing device; Fig.5 is a transversal sectional view of the closing device from the underneath; Fig.6 is a vertical sectional view of the outer cap; Fig.7 is a sectional view along A-A of fig.6; Fig.8 is a transversal sectional view of the outer cap from the underneath; Fig.9 is a sectional view of the bottle closure in its opened state.

Detailed Description of the Invention The bottle closure of the present invention consists of: - a spout 1 for pouring the liquid, - closing device 2, and - outer cap 3. The spout 1 for pouring the liquid can immovably be fixed on the bottle's neck 4 by means of its elastically deformable skirt 5 having inner protrusions 6. In the upper part of the spout 1 for pouring the liquid there are external threads 7 which movably connect the spout 1 with the closing device 2 through its corresponding inner threads 8. The closing device 2 in turn is connected with the outer cap 3 by means of a movable slip joint formed by protrusions 9 on the inner surface of the outer cap 3 and corresponding recesses between protrusions 10 on the external surface of the closing device 2. The outer cap 3 has a detachable element 11 of reduced rigidity for indicating an opened state of the bottle's closure once the bottle 2 has been opened located on an upper part of the outer cap 3. To remove the said detachable element of reduced rigidity 11 the closing device 2 has an external fore element 12 for providing a separating action on the element with reduced rigidity 11. To assemble the bottle's closure and prepare it for a first use, the spout 1 for pouring the liquid is mounted onto the bottle's neck 4 till connecting the spout's skirt 5 with protrusions 6 with a respective external surface of the bottle's neck 2. At the same time the inner channel part 13 of the spout 1 is inserted inside the bottle's neck 4, thus completely fixing and sealing the spout 1 for pouring the liquid on the bottle's neck 4. Thereafter, the closing device 2 is screwed onto the thread 7 of the spout 1 for pouring the liquid, thus closing the holes 14 designed for passage of the liquid to be poured. Finally, the outer cap 3 is mounted from the above both onto the spout 1 and closing device 2, coinciding the protrusions 9 of the outer cap 3 with the respective recesses between protrusions 10 of the closmg device 2. The outer cap 3 is immovably clipped in its final position with clips 15 embracing the spout 1 from underneath. The bottle closure is prepared for use. In order to open the bottle 2, it is necessary to rotate the outer cap 3. Since the outer cap 3 is connected with the closing device 2 by means of a movable slip joint consisting of protrusions 9 on the inner surface of the outer cap and corresponding recesses between protrusions 10 on the outer surface of the closmg device 2, the rotating action has been transferred from the outer cap 3 to the closing device 2 and closing device 2 changes its position upwardly along the thread 7. The upwardly rising external fore element 12 of the closing device 2 rests against the inner surface of the detachable element 11 of reduced rigidity and detaches it from the outer cap 3 along its perimeter. Simultaneously, the rising closing device 2 opens the holes 14 and the bottle's content can be poured out in a direction marked by arrows in fig.9. The bottle 4 can again be closed by rotating the outer cap 3 in an opposite direction and re-opened, however, the absence of the detachable element 11 indicates the bottle was once opened.
