RU189021U1 - PLASTIC LATCHED FILLING COVER SEALING DETECTING THE OPENING - Google Patents

Abstract

The cover-seal is used to seal vessels with an approximately cylindrical neck and serves to improve the guarantee function of the integrity of the vessel contents. The cover-seal contains on its side wall an embossing means for snap-on in the form of fastening tabs 3, which are mounted on the inner side surface of the cover-seal by more than one side, and vertical recesses located on the side wall of the cover — thinned zones 4 reaching the lower edge of the wall . The outer surface on the site of the recess is made smooth. 3 il.

Description

The utility model relates to a plastic snap-on lid-seal used for sealing vessels with an approximately cylindrical throat with a circular bead, for example, KEG fittings of beer types A (M), G, S (D), and serves to improve the warranty function of the inviolability of the vessel, provides visual inspection of the opening of the package.

Lids-seals do not have direct contact with food products; by their design features they are not intended for sealing packaging, they are single-use items.

The prior art technical solution "PROTECTIVE COVER FOR KEG FITTING" for the RF patent for utility model No. 71969, IPC B65D 51/20, published March 27, 2008. Known protective cover is designed to protect the end surface of the fitting from dirt and damage, while also providing the ability to detect illegal opening of the container. In the well-known solution, the task of controlling the opening of the container is solved by using parallel weakened lines on the inner surface of the end portion of the lid in the diametrical direction, which form a tear strip along the perimeter of the lid. The disadvantage of this design is to increase the consumption of materials in the manufacture of the protective cover, as the cover further comprises a tear-off strip.

Also widely known are protective covers containing on the side wall means for snapping the cover on the neck, which are made in the form of flat tongues angled to the side wall and preventing the cover from being removed. In particular, such solutions are presented on the Internet: http://www.rausch.ru/production/cover/rausch-ko, https://beer-technics.ru/kegi/remkomplekty/kryshka-plomba-dlya-keg- pod-fiting-a-detail.

A similar design is also known from the technical solution "Beer Keg Cap" for US Patent No. 4,779,750, IPC B65D 41/48, published on 10/25/1988, which is selected as the closest analogue. The known cover is also intended to protect against unauthorized opening of the container. The lid contains on the side wall extending means for snap-on the lid on the neck, which are made in the form of flat tongues angled to the side wall and preventing the lid from being removed. To open the lid and control the opening, a tear-off area is made on the upper surface of the lid using weakened lines. A disadvantage of the known solution is the possibility of unauthorized opening of the cover without breaking the tear-off area. This can be done due to the fact that the inclined flat tongues have sufficient elasticity necessary for the initial snap-in of the lid, but at the same time allowing you to bend part of the tongues without disrupting their integrity and remove the lid, and then put it back on.

The task of the utility model is to improve the warranty function of the known snap-on lid and create a plastic snap-on lid that reliably and noticeably indicates the first uncorking of the vessel, that is, the KEG fittings have already been uncorked.

The geometric shape of the snap-on lid-seal is expressed in the following: a lid-seal, made by pouring under pressure, has a round cylindrical shape, has a flat top, with a neck in the form of projections radially located along the periphery of the flat part, the sides of which form angles equal to 45 ° at the base of a relatively flat top, and the sides connecting the vertices have an edge bent outward, representing a junction of three vertically arranged edges, the average of which has a smaller thickness compared to extreme, and is translucent.

Figures formed from three vertically positioned ribs are connected by serrated protrusions in the form of fastening tabs, which are fastened along the inner side surface of the lid on more than one side to snap the lid seals on the jar neck, located along the lower edge of the side wall of the lid seals all around , forming the side of the cover-seal - skirt.

The location of the mounting edge on the lower part of the skirt is important in the production of a plastic cover by injection molding, since there is a bulk horizontal and vertical shrinkage of the product. This phenomenon is due to the laws of physics on the expansion and contraction of substances and materials in places of greater accumulation of material, in the proposed cover such a place is a skirt with a fastening rim.

The strength of the side wall of the lid has special requirements.

When uncorking, the lid wall should tear over a section of vertical ribs of lesser thickness, in the intermediate space between successive ribs, or along the upper surface of the lid.

The thinned area is preferably performed in such a way that the outer surface of the wall is smooth. On a smooth surface, the tear becomes especially easily noticeable.

A simple production variant of the above-described snap-on lid is that the entire lid is molded together in vertically arranged thinned areas in a single working operation.

Below, the utility model is discussed in more detail using execution examples.

The drawings show:

FIG. 1 shows a top view of a snap-on lid according to the proposed utility model.

FIG. 2 shows a side view of a snap-on lid with an embodiment of vertically arranged thinned zones 1, which are located in the intermediate space between successively arranged retaining elements of the side wall.

FIG. 3 - axonometric image of the cover-seal.

On the side surface of the wall 2 of the lid - the seals, on the periphery, the retaining elements are fastened - tabs 3, which, when the snap-on lid is fitted, are adjacent to the collar at the neck of the vessel.

Claims (1)

Plastic snap-on lid, revealing the opening, suitable for installation on the container with a thread on the neck, containing on its side wall embedding means for snapping through the side of the vessel in the form of fastening tabs that are mounted on the inner side surface of the cover on more than one side, and vertical thinned ribs reaching the lower edge of the side wall, demonstrating the presence of an external impact caused by the deformation or destruction of the thinned ribs.
