Switching structure capable of changing a discharging amount of a soft tube package

Abstract

A switching structure outer capable of changing a discharging amount of a soft tube package comprises a connecting head and an outer cap. A switching cap is movably disposed on the connecting head. At least one arch-shaped hook is formed on an outer peripheral wall of the connecting head. The connecting head has a neck which forms a seat downward from an upper end thereof Through holes are formed at a bottom of the seat, and a protrusion is disposed at a center of the seat. The switching cap includes a large cover fitting the arch-shaped hook and a small cover formed inside the large cover. A discharge outlet is formed at a center of the switching cap. This switching structure is capable of controlling an extruding amount of contents of the soft tube package effectively.

Description

TECHNICAL FIELD OF THE INVENTION[0001]This invention relates to a package for receiving liquid or paste substance and relates particularly to a switching structure capable of changing a discharging amount of a soft tube package.DESCRIPTION OF THE RELATED ART[0002]The advantages of a soft tube package are the light weight and the easy use. The soft tube package is not only applied to the food package but to the package of daily supplies, such as cosmetic products, toothpaste and shoe polish.[0003]The soft tube structure usually includes a soft tube, a tube neck integrated with the tube, and a tube cap fitting the tube neck. In use, the tube cap is directly opened, and the soft tube is squeezed to extrude contents of the soft tube. The extruding amount of the contents in the tube is decided according to how large a squeezing force is and how large a discharge outlet is. Generally, different users have different needs for the extruding amount per use. If the size of the discharge outle...

AI Technical Summary

Benefits of technology

The invention provides a simple switching structure that allows for easy control of the amount of material being extruded from a soft tube package. The structure includes an arch-shaped hook and a locking part that work together to create a one-way locking connection. The position of the hook and locking part determines if the discharge outlet is blocked, resulting in the control of the extruding amount of contents. The invention provides a convenient and user-friendly package design, and is quick and easy to use.

Problems solved by technology

If the size of the discharge outlet is larger, an over extruding amount caused by a larger force may incur an unnecessary waste.

If the extruded contents are refilled from the discharge outlet into the soft tube, an inconvenient operation is caused, and the original contents stored in the soft tube are easily contaminated when the extruded contents are refilled into the tube.

For some special contents of the tube, such contamination may affect the function of the product in the future use and impinge on the expiration of the contents.

If the size of discharge outlet is smaller, the user cannot extrude an enough amount of the contents at once, and the user needs to squeeze the soft tube repeatedly.

This incurs an inconvenient use.
