RU17776U1 - MEDICINAL VESSEL CAP - Google Patents

Abstract

A cap for sealing vessels with drugs containing a cylindrical part and a bottom, on which a tear-off section is located, bounded by a through slot and connected to the bottom by several jumpers, in addition, the tear-off section is connected to the tear-off strip, which is a continuation of one of the jumpers of the tear-off section and formed by lines weakening of strength, characterized in that the transverse edge of the through-slot is made at an acute angle to the longitudinal edges of the groove, forming voltage concentrators on through the slots near the lines of weakening of strength, limiting the tear strip, providing the direction of the separation force along the lines of weakening of strength.

Description

VESSEL CAP

WITH MEDICINES

The utility model relates to closures and can be used, in particular, in the medical industry for corking vessels with drugs, blood and blood substitutes.

Known cap for the vessel, closed with a rubber stopper, consisting of a cylindrical part and a bottom, which includes a tear off portion limited by an open through slot and connected to the cap by a tear strip formed by lines of weakening strength. These lines begin near the ends of the through-slot and extend along the bottom of the cap, (see US Patent No. 2.387.956, cl. 215-253).

The transverse edge of the through slot is made at right angles to the longitudinal edges of the slot. The separation force from the longitudinal edges of the slot is distributed along the length of the transverse edge and changes direction from the line of weakening of strength on both sides, which makes it difficult and even impossible to strip the strip and does not guarantee removal of the cap.

The purpose of the utility model is to improve the conditions for removing the cap by creating stress concentrators at the ends of the through slot.

This goal is achieved by the fact that the cap contains a cylindrical part and a flat bottom, in which at least one through slot is made that defines the area to be torn off, which is connected by one or more jumpers to the bottom of the cap. A peel strip is made on the cap adjacent to the peel area and is formed by lines of weakening strength. Strength weakening lines are made, for example, by complete or incomplete perforation from the inside of the bottom and directed towards the separation of the strip to the internal mating border of the bottom with the cylindrical part. Moreover, the transverse edge of the through slot is made at an acute angle to the longitudinal edges of the slot.

forming stress concentrators at the ends of the through-cut near the lines of weakening of the nostrils that limit the tear strip.

In FIG. 1 shows the inventive cap for capping the vessel, csf / o / y figure 2 is the same, view from the bottom, Fig.Z - sealed neck of the vessel; FIG. 4 - section aa in FIG.

The cap consists of a bottom 1 and a cylindrical part 2. A tear-off section 3 is made on the bottom, bounded by one or more through-cuts 4 and connected to the bottom by one or more jumpers 5. In the zone of the bridge 6, the width of which is greater than the width of the jumpers 5, the tear off section, the cap equipped with a tear strip 7, formed by lines 8 weakening the toughness, which are made, for example, by complete or incomplete perforation with the formation of blind or through holes 9 on the inner side of the surface of the bottom 1. Ends strength weakening lines 8 are located near the inner mating boundary of the bottom with the cylindrical part of the cap. The through slot 4 of the tear-off section is made in such a way that its transverse edge is made at an acute angle to the longitudinal edges of the slot, forming voltage concentrators 10 at the ends of the through slot. The proposed cap is made of flexible plastic material, for example, by stamping, and is designed to seal vessels with liquid media, in particular, drugs, blood and blood substitutes. The neck 11 of the vessel is pre-closed with a rubber stopper 12, and then the cap 13 is mounted and fixed on the neck with either a roll-up or stamping at several points around the perimeter of the lower cylindrical part.

To open the vessel, the operating staff engages the free end of the edge of the peeling portion 3 of the bottom of the cap with a hand or tweezers and, tearing the jumpers 5, bends it along the line of the jumpers 6, freeing up a zone on the rubber stopper designed to introduce a tool for removing fluid from the vessel. After using the contents of the vessel, take the bent peeled portion 3 by hand and, applying a regulated force

tearing in the direction of the tear strip 7, tearing the material along the line of weakening of strength 8. In this case, the stress concentrator 10 facilitates the rupture of the bridge near the line of weakening of strength 8 due to the fact that the acute angle of the stress concentrator directs the separation force along the line of weakening of strength to the mating boundary of the bottom with the cylindrical part of the cap. After that, the cap 13 is easily removed, allowing you to remove the rubber stopper 12 from the neck 11 of the vessel.

The advantage of the inventive cap with voltage concentrators at the ends of the through-cut near the lines of weakening of strength, limiting the tear strip, is the creation of reliable conditions for removing the cap due to the guaranteed separation of the strip at the bottom of the cap.
