Solution Overview
Problem
Existing devices for sealing containers in the cosmetic and pharmaceutical industries face challenges in achieving high throughput while maintaining low maintenance costs, as they require rapid movement of heavy caps and complex control mechanisms.
Innovation Solution
A device comprising a container feeding system, cap gripper units, and a capping unit with a screwing-on mechanism, where cap gripper units are positively guided by the capping device's movement, allowing for simultaneous sealing of multiple containers without intermediate stops, utilizing a driver element and spring-loaded lowering plate for efficient cap handling and simple design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional cap feeding mechanisms are used with intermediate stops, then control is simplified, but throughput speed decreases and maintenance costs increase
Solution Approach 1:
The patent combines the cap feeding device with the capping device into a single integrated unit. The cap feeding device includes a cap magazine and cap delivery mechanism that are directly coupled with the capping head, eliminating the need for separate control systems and intermediate stops. This integration allows the system to achieve high throughput speeds while maintaining simple control architecture.
2Productivity
If heavy caps are moved rapidly, then throughput increases, but wear and tear increases leading to higher maintenance costs
Solution Approach 1:
The patent employs pneumatic mechanisms to handle and deliver caps to the capping position. Compressed air is used to propel caps from the magazine through the delivery mechanism, enabling rapid movement of heavy caps without mechanical contact that would cause wear. The pneumatic system provides contactless transfer, significantly reducing maintenance requirements while maintaining high throughput speeds.
3Productivity
If multiple containers are sealed simultaneously, then productivity increases, but the complexity of coordinating cap delivery and capping movements increases
Solution Approach 1:
The patent divides the capping system into multiple independent capping heads, each capable of sealing one container simultaneously. Each capping head has its own integrated cap feeding and capping mechanism, allowing parallel operation without complex coordination between units. This segmentation enables high throughput while keeping individual unit complexity low and simplifying overall system control.

AI summary
The device for sealing containers comprises a container feeding device for an intermittent feed of containers in a transport direction, a cap feeding device having a plurality of cap gripper units; and a capping device movable in and opposite to a lowering direction. The capping device has a plurality of capping units corresponding to the plurality of cap gripper units in the cap feeding device. Each capping unit has a screwing-on mechanism at one end. Each screwing-on mechanism is adapted to pick up a cap and to seal the container with the cap in a lowered position of the capping device. The capping device and the plurality of cap gripper units of the cap feeding device are configured and arranged such that the plurality of cap gripper units of the cap feeding device are positively guided in the lowering direction.
