What is a Snap Capper?

What is Snap Cap/Lid?

A cap that is placed on a container without torquing is called a snap cap. A snap cap may be threaded or unthreaded. Snap caps snap onto the container over any threads, without requiring any torquing motion. Cleaning supplies, such as a canister of sanitizing wipes, are often fitted with snap caps. In addition, more flip-top lids are also snap-on lids.

Snap top caps are commonly used in food packaging and body care packaging;

What is a Snap Capper?

A snap capper is used to quickly and ergonomically apply push-on, press-on, or snap-on caps onto containers and bottles in various shapes and sizes. Thus, eliminating the tedious work of placing the lids by hand manually. They help prevent repetitive motion strains and injuries to your workers caused by the manual work of lid placement. Moreover, it removes human error to prevent costly spills.

Given the many types of caps that these machines can handle, they are also known by different names such as the following:

  • Press-on capping machine
  • Push-on capper equipment
  • Snap-on capping equipment

VKPAK’s snap capper uses the latest technology to automatically place and accurately snap down most snap down cap types onto most bottle types. The snap capper can place and snap down flat caps, oval caps, safety caps, child proof caps, or with over-caps or induction seals. The snap capper can handle almost any bottle type or shape including PET, PP, PVC, HDPE, LDPE, and Glass.

Why Use a Snap Capper?

Snap capper not only increase the speed of the packaging process but also make sure that each lid is sanitary. They help prevent the contamination of the products unlike when they are manually capped. Moreover, they allow the operators to save themselves from the repetitive motions caused by the manual placement and tightening of the caps into the containers.

Snap capper machines not only save you time but also decrease your operating expenses by:

  • Streamlining the cap placement process
  • Getting your products ready for delivery at a faster pace

For instance, instead of your workers manually sorting or placing and tightening the lids onto the containers, you can just let the machine do all of these tasks. Aside from automating the packaging process, snap capper machines also produce more uniform and consistent results.

Types of a Snap Capper

Whether a packaging line is designed for high or low production speeds, it will oftentimes require some kind of assistance for capping the containers. The goal of opting for a capping equipment is not limited to increased production speed. Container cappers give reliable and consistent seals to fight against overly tightened caps, loose caps, crooked caps, product leaks, and spills.

Automatic Snap Capper

Automatic snap capping machines are produced to provide your packaging lines a continuous capping of your containers. Most of these machines are equipped with conveyor and cap delivery systems such as a vibratory bowl or an elevator. The setup and control of automatic snap capping machines are achieved using control panels along with necessary levers and finger knobs.

Moreover, the operator is required to provide bulk quantities of lids to the cap delivery system. But once the capper machine is fully set up and the caps provided, the only thing the operator needs to do is to monitor the machine while the capping process is ongoing.

Semi-Automatic Snap Capping Machines

Semi-automatic snap capping machines can have various designs from handheld ones to tabletop machines to semi-automatic snap capping equipment built on automatic portable frames.

The main difference between semi-automatic snap cappers and fully automatic ones are based on the mode of operation of each machine. For semi-automatic snap cappers, the operator needs to manually place the cap or closure on the containers before putting the cap-container combination into the snap capper equipment.

Snap capping machines usually use plungers or snap-on belts to apply the pressure needed to snap the lids into the bottles. Moreover, snap capper machine manufacturers often add spindle wheels to the snapping device creating a snap capper equipment that can both snap and screw caps onto containers. These combined machines work best for companies or packagers handling a wide range of containers.

Components of a Snap Capper

#1 Cap/Lid Sorter and Feeder

These components of the machine sort and feed the right lids into the machine. The cap sorter’s design depends on the geometry of the cap being used. On the other hand, the lid feeder can be a vibratory bowl or a cap elevator.

#2 Press On Head

Snap capper machines have press on heads used to press the snap caps onto the containers to tighten the lid. It can be a single or multiple press heads, or a chain plate.

#3 Chute Parts

The machine needs the capper chute for holding the lids in position. It places the lids on each container that passes through the end of the chute before the container goes under the press on head for the snapping process.

#4 Conveyor Belts

The conveyor belts are continuously moving metal or rubber that moves the caps and containers towards the capping zone. They are very important components of an automatic snap capper equipment for transport because the machine depends on the conveyor belts to transport the containers to and from one point to another in the machine. Furthermore, they firmly guard the containers in position while the capping process is ongoing.

#5 Gear Boxes, Drives, and Motors

These components are also referred to as the snap capping machine’s engine. Together, they assist the snap capper machine by serving as drivers for the machine’s other components. The speed of the movement of the components will be determined by the settings you set on the control panel of the capping machine.

#6 Pulleys

The pulleys are connected to the machine’s conveyor belts and gears which means that they also play an important role in moving the machine’s components. They come in various sizes depending on your snap capper machine’s design.

#7 Shafts and Sprockets

The shafts and sprockets work together and assist in transmitting rotary motion to the shafts. Similar to the motors, drives, gearboxes, and pulleys, these two parts of the machine help in driving the other components of the machine during the capping process.

How Snap Capper Work?

A snap can capper equipment simply snaps a lid onto a filled container. Basically, the working principle of both fully automatic and semi-automatic can snapper machines are the same. The only difference is fully automatic snap cappers will use a cap sorter, feeder, and chute while semi-automatic ones will not have these.

Step 1. Provision of lids to the fully automatic cap capper machine.

For the snap cappers, the operator provides snap lids in bulk quantities onto machine’s cap feeder. The lids should be compatible with the containers to be capped.

Step 2. Feeding the lid snap capper machine with containers.

The operator feeds the machine with the filled and uncapped containers which will move towards the capping station via a conveyor belt.

Step 3. Snapping the loosely placed lid tightly into the containers.

The press on head automatically presses the loosely placed lid onto the containers to secure a tight seal.

Step 4. End of the capping process.

The tightly sealed containers will continue moving towards the end of the capping line and ready for bulk packaging and delivery.
