Current status and solutions for product residue problems

1. Status of product residue problems

A. Product residues are in the fields of food, cosmetics, etc.

B. There are currently no standards in laws and regulations.

C. Incomplete residue is a problem with packaging containers

D. Residues can cause consumer complaints

E. Residue is also related to the viscosity of the contents.

F. Normal residue should be around 10% (see different industries and products)

2. Case discussion

A. Case - new design

1. At present, the shampoo, body wash, and hand sanitizer used in our bathroom are bottled. After use, the bottle is thrown away, which is quite wasteful. Designer Bang Ki Ryoul & Junga Kim designed this bathroom washing bottle cover from the perspective of environmental protection and cost. It consists of a shell, plastic tube and nozzle. The bottle is packed into a bag and it is very convenient to use.

2. This type of packaging has a small residue and is much cheaper than a vacuum bottle.

3. Your design is very special and a good way to solve the residue.

B. A newly developed bb cream, the hose + pump head packaging test has a high residual amount of 15~20%, do you have a solution?

1. This is related to the hardness of the hose and the airtightness of the nozzle. Gas leaks back into the hose during use of the nozzle.

2. This design, the theoretical residual amount, will be 10 to 15%, about 20% is also possible, should be considered in the design. There is no obvious improvement in the calculation.

3. First improve from your current design, welcome a more attractive pump, optimize the design of the diptube, and the bottom of the bottle to contact, maximize the suction, test to the end, take a few shots, then spray

C. A well-known supplier in South Korea, the vacuum pump head adopts the structure of the bag, and the bag is squeezed and blown with LDPE, and the product utilization rate is over 95%, which has been tested and verified.

1. This should be a very thin blow bottle, placed in the bottle, using a vacuum pump.

2. Now the bottle of this supplier, the bag is developed in China, the five-layer squeezed bottle, in order to improve the barrier.
