Closure

Abstract

This invention can be used in the food industry. The invention relates in general to multi-purpose closures used for bottling and storing expensive high-quality drinks. The technical result of the proposed invention is a more reliable closing of bottles, providing the necessary tightness, and making refilling the bottle with low-quality drinks less possible. The closure comprises a discharge sleeve with outer and inner pipes at its inlet end, a collar with an external thread at its outlet end, an inner hood with splines on its side exterior surface and a pouring tube at its outlet end, a removable check valve installed on the exterior side surface of the inner pipe, said check valve having sealing lips on its exterior surface and a flange on its outlet end, said flange being located between the inner and the outer pipes. The outer pipe has longitudinal ribs on its interior surface. The collar of the discharge sleeve has a plug installed therein, said plug being supported by raking props and used to shut off the pouring tube. The inner hood is threadedly engaged on the collar of the discharge sleeve thereby to allow its axial movement resulting from rotation. The outer hood has a tamper-indicating means at its outlet end, splines on its interior side surface thereby to engage splines on the inner hood, and transverse projections to interact with the inlet end of the outer pipe of the discharge sleeve. The discharge sleeve has windows evenly spaced around its periphery. The mating surfaces of the pouring tube and the plug are tapered. The tamper-indicating means at the outlet end of the outer hood is made as a break-away member fixed on the end surface by means of at least three break-away strips, which are spaced evenly around the periphery of the interior surface of the end of the outer hood, or by means of a solid annular break-away strap located at the interior surface of the end of the outer hood. The ball of the valve is made of e.g. glass, crystal glass, marble. A sealing gasket is placed between the outer pipe and the inner pipe of the discharge sleeve. The longitudinal ribs on the interior surface of the outer pipe are separated or arranged in groups to interact with the mating surface of the bottleneck collar.

Description

The proposed invention will now be explained by way of the non-limiting description of the preferred embodiments and with the reference to the accompanying drawings in which:

FIG. 1 is a view of the section of the closure;

FIG. 2 is a view of the section of the hood;

FIG. 3 is a view of the section of the discharge sleeve without the removable gate.

The closure comprises a discharge sleeve 1 with an outer pipe 2 and an inner pipe 3, the outer pipe having longitudinal ribs 4 and a collar 5 with an external thread 6, an inner hood 7 with splines 8 and a pouring tube 9, said inner hood being engaged to the collar 5 of the discharge sleeve 1 by means of a thread 10, a removable gate 11 including a seat 12 and a check valve member 13, a sealing lip 14, a flange 15, an outer hood 16 with splines 17, transverse projections 18, a break-off member 19, and breakable strips 20. There is a plug 21 inside the collar 5 of the discharge sleeve 1, which is supported by raking props 22 and used to shut off the pouring tube 9, and there are windows 23 with inwardly bent projections 24 on the wall of the discharge sleeve 1 above the longitudinal ribs 4, said windows being spaced evenly around the periphery of the discharge sleeve.

The mating surfaces 25 of the pouring tube 9 and the plug 21 are tapered.

The closure can be equipped with a sealing gasket 26.

The proposed closure will be assembled and used as follows.

The inner hood 7 is screwed hard on the discharge sleeve 1, which results in the plug 21 closing tightly the bore of the pouring tube 9. Then the discharge sleeve containing the inner hood will be inserted fully into the outer hood 16, thereby the splines 17 of the outer hood 16 engage the splines 8 of the inner hood 7, and the lower end of the outer hood 2 is restrained against the axial movement by means of the transverse projections 18. Afterwards, the valve member 13 will be placed into the removable gate 11, and the removable gate will be inserted into the discharge sleeve through the inlet end using some force. The sealing gasket 26 will be installed onto the flange 15, if necessary. The assembled closure will be forced hard onto the bottleneck. After that, the inwardly bent projections 24, sealing lips 14, located on the exterior surface of the removable gate 11, and the splines 17 sit tight on the bottleneck, inside and outside. As a result, the bottle is sealed tightly.

To open the closure for the first time, the outer hood 16 will be screwed counterclockwise, thereby breaking the strips 20 and releasing the break-off member 19 due to the rise of the inner hood 7 relative to the collar 5. As a result, the bore in the pouring tube 9 opens, and the contents of the bottle can be discharged.

To close the bottle, the outer hood should be fully screwed clockwise.

Claims

1. A closure comprising: a discharge sleeve with outer and inner pipes at its inlet end, a collar with an external thread, raking props and a plug at its outlet end; an inner hood with splines on its side exterior surface and a pouring tube at its outlet end, said inner hood being threadedly engaged on the collar of the discharge sleeve thereby to allow its axial movement resulting from rotation, a removable gate installed on the exterior side surface of the inner pipe, said gate having sealing lips on its exterior surface and a flange on its outlet end, said flange being located between the inner and the outer pipes, an outer hood having a tamper-indicating means at its outlet end, splines on its interior side surface thereby to engage splines on the inner hood, and transverse projections to interact with the inlet end of the outer pipe of the discharge sleeve, said outer pipe having longitudinal ribs on its interior surface, said plug being supported by raking props and used to shut off the pouring tube, the wall of the discharge sleeve has windows therein, said windows being spaced evenly around the periphery of the wall of said discharge sleeve, and inwardly bent projections located under the said windows, characterized in that the mating surfaces of the pouring tube and the plug are tapered, the tamper-indicating means at the outlet end of the outer hood is made as a break-away member fixed on the end surface by means of at least three break-away strips, which are spaced evenly around the periphery of the interior surface of the end of the outer hood, or by means of a solid annular break-away strap located at the interior surface of the end of the outer hood, and the valve member is made of a material which ensures its tight abutment to the seat of the removable gate.

2. Closure as claimed in claim 1, wherein the ball of the valve is made of e.g. glass, crystal glass, marble.

3. Closure as claimed in claim 1, wherein a sealing gasket is placed between the outer pipe and the inner pipe of the discharge sleeve.
