Flexible Anti-Theft Device for Flowable Material Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-theft devices for containers with flowable materials do not effectively prevent theft by ensuring the anti-theft tag cannot be easily removed without activating an alarm, as they lack a secure mechanism to inhibit removal once inserted.
Innovation Solution
A container-insertable anti-theft device with a waterproof main housing containing an electronic article surveillance marker and flexible elongated protrusions that can be force-fitted into a container, making it difficult to remove without triggering the alarm, featuring multiple segments that lock the device in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing anti-theft devices are used for containers with flowable materials, then the anti-theft tag can be attached to the container, but the device can be easily removed from the container without activating an alarm
Solution Approach 1:
The device employs a dynamic insertion mechanism where the elongated protrusion is flexible during insertion to pass through the container opening, then becomes rigid or locked in place upon insertion to prevent removal. This dynamic behavior allows easy insertion while ensuring secure retention and making removal difficult without triggering the alarm.
Solution Approach 2:
The anti-theft device is divided into distinct segments: a main housing containing the EAS marker and separate elongated protrusions that extend from the housing. These protrusions can be inserted into the container independently and lock into place, creating a segmented structure that secures the device to the container while maintaining the alarm function.
2Reliability
If the anti-theft device is made secure to prevent removal, then theft is deterred, but the device becomes complex in structure
Solution Approach 1:
The elongated protrusions serve multiple functions: they act as insertion guides to help the device pass through the container opening, serve as retention elements that lock the device in place within the container, and provide structural support. This multi-functionality reduces the need for separate components, thereby simplifying the overall device structure while maintaining secure anti-theft protection.
Solution Approach 2:
The invention merges the EAS marker housing with the retention mechanism by integrating the elongated protrusions directly into the main housing. This combination eliminates the need for separate attachment devices or complex mounting structures, achieving secure theft prevention through a unified, simpler device design.

AI summary
A container-insertable anti-theft device includes: a main housing containing an electronic article surveillance marker, the main housing being waterproof; and at least one elongated protrusion extending from the main housing, the elongated protrusion being flexible and having a length equal to at least the longest dimension of the main housing. There is also an anti-theft system that includes: (a) a container for strong flowable material having a hollow main body, a pour orifice and a closure for the pour orifice, the container having a maximum internal diagonal dimension x; and (b) a container-insertable anti-theft device that includes: a main housing containing an electronic article surveillance marker, the main housing being waterproof and having a predetermined length y; and, at least one elongated protrusion, the elongated protrusion being flexible and having a length, wherein the sum of the lengths y and y are greater than x, such that the container-insertable anti-theft device may be flexed and force-fitted into a maximum internal diagonal of the container, locking it therein so as to deter easy removal therefrom.
