AI Technical Summary

Benefits of technology

The invention is a pliable package for storing liquids that includes flexible sheets joined together by a liquid-tight seal, a liquid reservoir with a funnel-shaped outlet passageway and a reinforced closure, and a method of storing liquids inside the package. The package prevents spillage and kickback of the liquids during unblocking of the liquid discharge opening and eliminates the risk of a pet or child of swallowing a twist off device. The technical effects of the invention are improved safety and convenience for storing and using liquids.

Problems solved by technology

Conventional designs, however, suffer from many drawbacks.
For instance, typical container designs are not adequately childproof.
They are not sufficiently tear resistant to insure that the enclosed liquids are used for their intended uses.
Nor do conventional designs adequately prevent liquid from being accidentally discharged during the process of opening the container.
In addition, current designs are susceptible to uncontrolled discharge after opening because they typically permit liquid to freely flow through the torn opening.

Embodiment Construction

[0036]Reference will now be made in detail to the present embodiment of the invention, an example of which is illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0037]One embodiment of the invention as shown in FIGS. 1 and 2, includes a tear resistant package 5 that has a bottom layer 10 and a top layer 15 adhered to the bottom layer 10. The package shape is generally symmetrical about a longitudinal axis 18. The bottom and top layers 10, 15 are together shaped to define a base portion 20 (alternatively referred to as an “applicator”) and a non-removable tab portion 30. In a preferred embodiment, the tab portion 30 may remain attached to the base portion 20 after the package 5 is opened. Alternatively, the tab portion 30 could be removed from the base portion 20 by cutting with scissors or another cutting implement. Two cross-sectional perspective views of the package 5 are s...

Abstract

The present invention is directed to a pliable package that is tear resistant, requires a greater degree of dexterity to open, and prevents accidental discharge during or after opening of the package. The package includes a flexible, liquid storage reservoir having a funnel-shaped outlet passageway leading to a opening. The package also includes a reinforced tear resistant tab portion that may prevent accidental discharge of liquid when the tab portion is bent about the score line. The funnel-shaped outlet passageway may be shaped to allow the liquid to be dispensed in a controlled manner.

Description

RELATED APPLICATIONS[0001]The present disclosure claims the right to priority based on U.S. Provisional Patent Application No. 60 / 788,572 filed on Mar. 31, 2006.BACKGROUND OF THE INVENTION[0002]I. Field of the Invention[0003]The present invention relates generally to dispensary packages. More particularly, the present invention relates to veterinary packages for dispensing liquids.[0004]II. Description of the Related Art[0005]Over the years, designers have sought to improve container designs and processes for dispensing liquids. Conventional designs, however, suffer from many drawbacks. For instance, typical container designs are not adequately childproof. They are not sufficiently tear resistant to insure that the enclosed liquids are used for their intended uses. Many containers can be opened relatively easily, such as by twisting one part of the container relative to another. Nor do conventional designs adequately prevent liquid from being accidentally discharged during the proce...
