Many purchasers may think that the glass shaker bottle is a high-quality product, but in fact, it is a wrong choice. Here, we will offer you a detailed introduction to the defects of glass shaker bottles and other better alternative materials, to help you gain a clear understanding.
What Is A Shaker Bottle?
The shaker bottle is a mixing tool designed especially for quickly and thoroughly dissolving powdered beverages. Apart from the bottle body and lid that are similar to those of an ordinary bottle, it also has core components such as a stirring ball inside. At present, it is widely applied in various scenarios such as fitness, office work, and outdoor activities, etc.
What Is A Glass Shaker Bottle?
The glass shaker is a shaker bottle made of glass material, and is equipped with components such as a plastic lid and a silicone sealing ring. And basically, it achieves the great mixing effect of powder and beverages through manual shaking.
The Shortages Of Glass Shaker Bottles
Fragile
Being fragile is the most prominent drawback of glass. This drawback makes the glass shaker bottle have many application defects that cannot be avoided or improved.
Due to the lack of the ability to undergo elastic deformation, glass is unable to withstand general external impacts. Therefore, sometimes even a minor impact can cause cracks in the glass. Furthermore, in some severe cases, such as falling, it is very likely to break.
The resulting consequence is that the generated debris is prone to scratching users, thereby bringing a certain risk of use. Even if no fragments are produced, cracks in the glass can affect the appearance of the shaker bottle and increase the potential risk of injury.
Overweight
The high density of the glass material will make the glass shaker bottles overly heavy.
Not only is the glass shaker bottle itself heavy, but after filling it with liquid, the sense of weight becomes even more obvious. Therefore, carrying the glass shaker bottle will cause unnecessary physical exertion and increase the burden on the user.
At the same time, excessive weight will also increase the risk of falling, which will not only easily make the shaker bottle break, but the sharp glass fragments also pose a safety hazard of scratching and cutting.
High Thermal Conductivity
Glass is a good conductor of heat. This material property gives the shaker bottle the characteristics of fast heat transfer and high thermal balance efficiency. However, this has become a fatal weakness in aspects such as safety protection and functional experience.
On the one hand, the high thermal conductivity of glass material causes the temperature of the bottle body and the beverage to synchronize rapidly, which results in an uncomfortable sensation of either burning or freezing hands.
On the other hand, the feature of the single temperature conduction can only accommodate room-temperature beverages and thus cannot meet users’ diverse demands for cold and hot drinks.
Limited Application
In terms of application environments, the glass shaker bottle has significant limitations. Overall, glass shaker bottles are not suitable for the following major scenarios: sports and fitness, outdoor activities, daily commutes, and travel.
Specifically, in general fitness scenarios, the glass shaker bottle cannot adapt well to the vibrations and compressions during exercise, and is extremely prone to dropping or bumping. The resulting broken glass can cause a scratch issue.
And if it’s an outdoor activity in a high-temperature environment, it will accelerate the aging of the bottle body, and at the same time, the temperature fluctuations will increase the risk of breaking.
As for daily commuting or traveling, the glass shaker bottle is prone to getting damaged when carried with keys, power banks, and other items. Therefore, it is not a good choice either.
Replaceable Materials For Shaker Bottles
Since glass is not a good choice, you can choose other materials, such as stainless steel and plastic, as an alternative.
Stainless Steel
Basic Properties
If you are not particular about weight and want to choose an extremely durable shaker bottle, a stainless steel shaker bottle is your best choice.
The bottle made of stainless steel has high toughness and excellent resistance to compression and impact. Even if it is bumped or dropped, it will not break or shatter, which makes it perfectly suitable for frequent and dynamic usage.
In addition, it can store hot, cold, and normal temperature beverages, and has a strong effect of preserving temperature, which can well maintain the original taste of the drinks.
Optional Materials
We provide you with 304-type and 316-type food-grade stainless steel materials.
If you only need to meet the basic needs of warm water, protein powder, etc., you can choose the 304 type, which is the most cost-effective. If you need to store sports drinks and high-salt beverages, you need to choose the 316 type, which has better resistance to corrosion.
Plastic
Basic Properties
If you want a lighter, more durable shaker bottle, you can choose the plastic one.
The plastic shaker bottle is the most popular option recently. Although it is light, it is shock-resistant, perfectly solving the critical issues of being heavy and fragile for the glass shaker bottle. At the same time, its cost is lower. And if you don’t have high requirements for insulation, it is a safe choice.
Optional Materials
We have provided you with two different types of plastics: Tritan and PP.
If you are willing to sacrifice a little bit of cost for the sake of superior material quality, you can choose Tritan. It has high transparency and looks very high-end. At the same time, although it is lightweight, it also has good toughness. In addition, it is safe, non-toxic, and has no odor. Totally, Tritan material is much superior, and you can choose it with confidence.
If you want a more affordable shaker bottle, you can choose the one made of PP material. Although the food-grade PP type has average transparency and is prone to scratches, it is still safe, non-toxic, and can resist high temperatures and corrosion. So, if you just want to meet the needs of daily use, you can choose this shaker bottle.
FAQ
Why Is the Cost of a Glass Shaker Bottle Higher?
The high cost of glass shaker bottles mainly stems from two core factors: damage cost and transportation costs.
On the one hand, glass itself is fragile and is prone to damage during production and transportation, resulting in additional loss costs. On the other hand, glass shaker bottles usually require thicker packaging, which significantly increases packaging costs. Moreover, the return and replacement of damaged products will further raise the overall cost.
Why Does the Production Cycle of Glass Shaker Bottles Take Longer?
The main reason is that the process is complex, and it is difficult to change the design.
The glass material needs to go through multiple processes, and the precision requirements for glass forming are high, so it’s hard to control the yield rate, thus prolonging the production cycle. Furthermore, once the design needs to be adjusted, the glass shaker bottle has to have a new mold, which further lengthens the overall production cycle.
Why Must a Glass Shaker Bottle Be Replaced Immediately After Fine Cracks Appear?
This is for safety and hygiene considerations. During use, the tiny cracks on the shake bottle will continuously extend and expand. Ultimately, this will lead to a sharp decline in the structural strength of the bottle, making it highly prone to sudden cracking and shattering, which may cause serious injuries such as burns and cuts.
In addition, the crack is difficult to clean, making it easy to breed bacteria and residual stains.
Why Can’t Boiling Water Be Directly Poured into a Glass Shaker?
This is mainly to prevent the glass from shattering and, at the same time, avoid the risk of burns. The high temperature of boiling water will cause the body of the glass shaker bottle to expand instantly, and the inner wall will thus generate huge internal stress, which may lead to the shaker bottle’s body cracking and shattering. This will not only damage the bottle but also cause burns due to the splash of boiling water.
Why Must Families With Children Or The Elderly Avoid Using Glass Shaker Bottles?
Because glass shaker bottles pose risks to these groups of people. These two types of people often break the bottles when taking them, and the fragments are very likely to scratch them.
Moreover, glass is highly conductive and can get hot when holding hot water, making the elderly and children more prone to burns. If you want to avoid these related after-sales disputes, please do not choose glass shaker bottles.
