Cap for Containers with Improved Sealing

Abstract

A cap for containers, comprising a cylindrical body comprising a cylindrical skirt and a rib on the inner face thereof, where the cylindrical skirt and the rib are sized for contacting the inner face of the neck of the container and creating at least two sealing areas.

Description

BACKGROUND1. Field of the Disclosure[0001]The present disclosure belongs to the field of closure elements for containers, and more specifically caps for containers with a leaktight closure. An object of the disclosure is to therefore provide a cap for containers capable of assuring the sealing of the content.[0002]Another object of the disclosure is also to provide a cap for containers capable of improving tightness with the neck of the container, such that the resistance to pressures or damage sustained during transport is improved.[0003]Another object of the disclosure is also to provide a cap for containers capable of improving stability against the risk of sliding and seal loss during palletization, storage or horizontal transport operations.2. Discussion of the Background Art[0004]In the field of caps for containers, those caps with a contact surface provided for being coupled to the neck of a container and preserving its content are known.[0005]Generally, caps of this type use...

AI Technical Summary

Benefits of technology

[0014]In one embodiment of the disclosure, the cylindrical body is formed by the articulated attachment of two superimposed parts, a lower part and an upper part. In this sense, the double-sealing solution of the present disclosure described above is advantageously arranged in the upper part of the cap, so, in addition to the caps described above which are formed by a single rigid body, the present disclosure is also adapted to caps of this type having two bodies which are widely used, for example, in oil bottles or small water bottles. Additionally, a particular embodiment contemplates for the lower portion to be provided with gripping means for the retention thereof on the neck of the container and the upper portion to be provided with the cylindrical skirt and the rib. Advantageously, this configuration keeps the cap, specifically its lower portion, coupled to the neck of the container at all times, so the loss thereof is prevented and there is only a need for a simple movement of the upper portion of the cap which fits into the neck by pivoting about the hinge-type articulated attachment, the container being closed and sealed.

[0015]According to the foregoing, the present disclosure contains a series of technical features involving advantageous technical effects which mainly include, among others, improvement of the sealing that is provided. Therefore, the present disclosure prevents dust and / or foreign bodies from entering the container, preventing them from coming into contact with the content thereof. Advantageously, the double-sealing solution of the present disclosure is applicable to all types of caps, such as for example caps having a single body, caps having two parts attached to one another by means of a hinge or any other variation.

[0016]Since they are located in the inner area, the two sealing areas provided by the cap reduce the weight of the cap and use a clean surface of the neck of the container for contact. Furthermore, the risk of receiving blows is lower in the inner area than in the outer area of the neck, which allows better withstanding any pressure or damage sustained during transport or palletization. On the other hand, the two inner circular contacts that are provided assure good vertical stability of the cap when it is placed on the neck of a bottle and excellent stability against any risk of sliding and seal loss in warehousing or horizontal transport operations.

Problems solved by technology

However, caps of this type have a series of drawbacks.

These notably include, among others, the fact that these caps often close the container through the outer side of the neck thereof and the presence of small burrs causes the sealing to be inadequate.

Likewise, even starting from an initial leaktight situation, due to the configuration thereof, it is common for storage or transport operations to cause a critical sealing deformation, even giving rise to leakages.
