    These plastic containers feature wide mouths, light-weight, and unbreakable bottles. Capsules & Pill Bottles are perfect for easy filling and dispensing pills, capsules, vitamins, nutritional supplements, and more.

    The bottle cap is an important part of the bottle. Its function is mainly to isolate the influence of the external environment on the contents, and on the other hand, it also plays a certain decorative role.

    There are 3 main types of Capsules and Pill Bottles from their caps.


    Ordinary Cap Bottles

    Ordinary Cap BottleGenerally, drugs that do not have special requirements for bottle caps will choose ordinary screw caps. To ensure the bottle has a good seal, this type of bottle cap is sealed with an aluminum foil gasket.

    Its function is mainly used to block the direct contact between the bottle mouth and the inside of the bottle cap, so as to prevent the bottle cap from being unable to completely block the external air.


    Press-screw Cap Bottles

    Press-screw Cap Bottle: This is a special kind of cap. It consists of an inner and outer double-layer structure. When opening, it is necessary to apply downward pressure while twisting the cap.

    This opening method is difficult for children who are still in the developmental stage, so as to avoid the occurrence of accidental ingestion of medicines by children.


    Moisture-proof Cap Bottles

    Moisture-proof Cap BottleThis is a new type of cap that combines desiccant and cap into one. Generally, the desiccant will be placed inside the bottle in the form of a bag. The moisture-proof cap uses the space at the top of the bottle cap to place the desiccant in the small medicine compartment on the top of the bottle cap.

    It not only avoids direct contact between the medicine and the desiccant but also prevents children from accidentally eating the desiccant.

    2. What Are the Main Colors of Capsules & Pill Bottles?

    After learning about the types of capsule and pill bottles, you may be wondering why the same bottle has different colors. Why is this? The reasons are below.


    Capsule Bottles with Different Colors -photo credits: shutterstock

    Capsules & Pill Bottles are a common way of bottling pharmaceutical dosage forms in our lives. According to the different properties of drugs or the different needs of pharmaceutical factories, such packaging presents different colors, among which white, brown, and transparent are the most common ones.


    White Capsule Bottles -photo credits: uline

    White: Widely used color. Generally, medicines without special needs will choose white pill bottles. This is because white is a light color that reflects light. If it is dark, it will be exposed to sunlight.

    After the drug absorbs light, it is easy to deteriorate. On the other hand, white also gives a particularly clean and elegant feel, which is perfect for pharmaceutical packaging.


    Brown Capsule Bottles -photo credits: silverspurcorp

    Brown: The brown capsules & pill bottle are the color masterbatch added to the processing raw material, which changes the original color. Some drugs are easily decomposed and deteriorated when exposed to light.

    This color prevents exposure to visible light. It is mainly suitable for light-sensitive drugs.


    Transparent Pill Bottles -photo credits: freepik

    Transparency: This kind of capsule & pill bottle is mostly made of polyester raw material. The shape and color of the medicine can be observed through the transparent bottle body.

    It is mainly suitable for the packaging of solid medicines such as candy tablets and liquid calcium. Transparent packaging of medicines of various colors can also improve the overall aesthetics of medicines.

    The different shapes of different bottles have been poured into the designers’ efforts. Different capsules and pills will be packaged in different-shaped bottles.

    • Round Capsule & Pill Bottles

    These occupy a large proportion of pharmaceutical packaging, mainly due to the following benefits:


    Cut Costs -photo credits: thundertix

    Cost Saving: From a mathematical point of view, when the perimeter is fixed, the circular area is relatively large, and the nearly circular shape can save raw materials, which is the main reason for vigorously choosing round bottles.

    Durable and Beautiful: From an aesthetic point of view, due to the habit of long-term development, the round shape is more in line with the aesthetics of most people.

    Capsules and pill bottles are large or small. The size of the bottle is determined by the manufacturer according to the consumer demand for the capsule. For example, in the process of taking a drug, if the demand for capsules is relatively large for the entire course of treatment, the manufacturer will choose a larger bottle to pack.

    The bottle size of capsules and pills is defined in 3 ways.


    Pill Bottles with Different Capacities -photo credits: healthline

    Capacity: Due to the particularity of drug packaging and medication, from a few milliliters to about 1000 milliliters, most of the capsule & pill bottle shapes are round, and there are also square, oval, and other shapes.

    Protection: In order to ensure that the medicine is not damp or deteriorated within the validity period, the medicinal plastic bottle should have good sealing and barrier properties, which can prevent the influence of light, heat, water vapor, oxygen, etc. on the medicine.


    Drug Safety -photo credits: drugwatch

    Safety: The inner wall of the bottle is in direct contact with the medicine. Bottle-making materials must meet the requirements of drug packaging to ensure the safety of drugs.

    Through these three aspects, you can understand why the capsule or pill bottle is designed to be large or small.

    Drugs are related to the health and safety of your health, so drug packaging should also meet the following three basic requirements:

    • Requirements For Using in Different Circulation Conditions

    Capsules & pills in the circulation field may be affected by transportation and handling conditions, climate change, storage time, etc., so the capsule & pill bottles should adapt to these conditions.

    For example, the packaging measures for capsule & pill bottles should be considered in areas with high humidity. If the capsule & pill bottles need to be exported, the climate of the exporting country should also be considered.


    Humidity -photo credits: goblueox

    • It Should BAdaptedTo the Content

    The main concern here is the compatibility of the capsules & pills with packaging materials. According to the physicochemical properties and dosage form characteristics of the contained capsules & pills, different measures are taken.

    If capsules & pills are exposed to light, it is easy to deteriorate and the capsules & pills are easily oxidized in the a. So capsules & pills should be placed in a light-shielding container to ensure the stability of the medicine.


    Light-shielding Capsule and Pill Bottles

    • Meet the Standardization Requirements

    Bottles that meet the standardization requirements are conducive to ensuring the quality of drugs, facilitating drug transportation, loading and unloading, storage, and facilitating identification and measurement.

    The above are the three basic requirements that capsules & pill bottles must meet. In addition, the packaging of capsules & pill bottles should also take into account the requirements of external labels and bottle caps.

    The labels of special management capsules & pills, nonprescription drugs, and external use drugs must be printed with prescribed signs.

    11. What Are the Common Processing Technologies for Capsule and Tablet Bottles?

    Capsules & pills are the mainstream dosage form in today’s medicines, with the characteristics of accurate dosage and easy portability. Capsules & pills are packaged in blister packs, and bottles, among which capsule & pill bottles are the most commonly used.

    The commonly used processing techniques include the following:

    • Injection Blowing Molding


    Injection Blowing Molding -photo credits: petallmfg

    Firstly, the injection machine injects the molten plastic into the injection mold to form the tube blank. The tube blank is formed on a hollow punch with micro-holes in the peripheral wall. The tube blank is then moved into a blow mold while it is still hot.

    Then, the mold is closed, and compressed air is introduced into the pipe of the mandrel. The parison is inflated and attached to the cavity wall of the mold.

    • Injection Molding


    Injection Molding -photo credits: wikipedia

    It refers to the process of making semi-finished parts of a certain shape from molten raw materials through operations such as pressurization, injection, cooling, and separation.

    This process adopts automatic production. The product quality is stable. The size is accurate. The scope of application is wide, and there is no seam.

    • Extrusion Blow Molding


    Extrusion Blow Molding -photo

    It is a one-shot molding process, which is different from injection blow molding. The most commonly used materials in this process are polyolefins such as Low-Density Polyethylene (LDPE), High-density polyethylene (HDPE), and Propene Polymer (PP).

    • Injection Stretch Blow Molding

    First, the blank is injected by the injection molding machine. The hot parison is then stretched longitudinally, and then compressed air is introduced to stretch it laterally.

    A product with the same shape as the mold cavity is obtained. This process is generally used for tablet medicine bottles made of PET.


    Through the above description of the size of the capsules & pills and the size of the bottles, you can have a certain understanding of this. By referring to this article, you can know the size of your capsules and tablets, and the number of capsules you need to fill, so as to choose the matching capsule bottle.
