Problems solved by technology

This will reduce the effective extraction of liquid because the elongated protrusion structure will limit the amount of squeeze applied to the liquid
Furthermore, since the elongated protrusions are still in the liquid after being separated, the elo

Embodiment Construction

[0017] Figures 1 and 2 show preferred embodiments of the closed opening device. In the preferred embodiment, the closed opening device is used in an elongated tube housing 1 having a closed end 2 and an open end 3 . An application tip 4, such as a cotton swab, a foam tip or a brush, can be connected to the open end 3 of the elongated tube housing. A fluid 5 is sealed in the elongated tube housing 1 close to the closed end 2 . A closed opening device 6 is arranged in the elongated tube housing 1 to seal the fluid 5 in the elongated tube housing 1 . The opening device 6 is operated by bending the elongated airtight container 1 at or near the closed opening device 6 . The opening device 6 can be placed anywhere in the elongated tube housing 1 . As shown, opening means 6 may be placed near the open end 3 of the elongated tube housing 1 so as to open the opening by pressing the open end 3 on a surface allowing the elongated tube housing 1 to bend device6. As shown in Figure 2,...

Abstract

An elongated sealed container with a self-contained opening means fully enclosed within the container to release a fluid sealed within the container when the container is bent at or near the enclosed opening means. Once the enclosed opening means is opened, the fluid sealed within the elongated sealed container may be released for application.

Description

technical field [0001] The invention relates to a hermetic container sealed inside with an opening device for allowing liquid sealed in the container to flow out. Background technique [0002] There are many types of opening devices used to open containers. Most opening devices are screw-on or snap-on caps. Some opening devices are frangible seals or lines provided on the container to facilitate the flow of the contents of the container from the container when the frangible seal or line of the container is broken. All of the above opening devices are externally attached to the container, or formed as part of the container, where the former may be of the screw-on or snap-on cap type, while the latter may be a frangible seal or rupture line on the container . None of the opening means described above is designed to exist inside the container to seal the liquid in the container while at the same time ensuring that the liquid can flow easily from the container. There is a pa...
