Description

  The present invention relates to an improved bottle of liquid products, in particular pharmaceutical, medical or cosmetic products.

  The pharmaceutical and cosmetics industry knows plastic bottles that are used to package one or more doses of liquid, liquid or pasty products, which are based on the container body that contains the product. Made at one end and extending to the neck at one end, forming a product dispensing opening at its top, which is closed by a tearable membrane.

The end of the container body opposite the neck is open, allowing introduction of the product into the container body during bottle packaging, after which it is closed, for example by sealing.
A cap is fitted over the neck and a membrane perforation element extends inwardly from the ceiling.
A retaining ring is obtained on the inner surface of the cap, and in a closed arrangement during bottle wrapping, the membrane is engaged by a trigger in a corresponding ring-shaped thread formed on the outer surface of the neck and closes the dispensing port. Hold the drilling element to a certain height above it.

In use, the cap is snapped into the neck of the container body until the retaining ring disengages from the corresponding thread and the piercing element tears the membrane and opens the dispensing port, after which the cap is removed from the neck to dispense the product. Enable.
In addition, the container body has a pair of gripping flaps extending in opposite directions from the outer surface.

Known bottles can be made in a single unit or connected in series with each other (strips); in the latter case, the gripping flaps of the container body of two consecutive bottles have been pre-ruptured Temporarily added along the line.
These bottles nevertheless have room to accept improvements, especially to avoid potentially harmful use of the products they contain.

In particular, the known bottles do not have safety measures suitable to prevent or at least not easily prevent children from opening the dispensing opening and removing the cap. If children swallow products in bottles in an incorrect way, there is a clear health risk.
Furthermore, such bottles do not show any foreign matter and / or already opened, including unconscious, in a clear and readily perceptible manner, and do not guarantee the complete and sterile state of the product to be contained.

  In fact, bottles handled or placed in storage units (drawers, wardrobes, convenience cases, etc.) should push the cap against the neck before the product is actually used and before the perforating element tears the membrane. It ’s also possible to get a big blow. The impediment provided by the connection of the retaining ring with the corresponding ring-shaped thread groove rarely contrasts with a bang.

In order to eliminate at least some of these drawbacks, the bottle protrudes from the container body in a radially opposite direction and is arranged between the grip flap and the cap, along the respective weak part, It is known to include a pair of sealing flaps that are tearably coupled to a gripping flap or cap.
When the bottle is used by rotating the cap, it is clear that the above mentioned weak breakage was obtained and thereby opened.

However, the bottle does not have the above-mentioned safety measures appropriate to prevent it from opening or at least not to be easily opened by children.
Different types of liquid product bottles are made with a single body element, i.e. the product container body is formed without any obstruction with a single body closure.

The closing means is connected to the body by a deformable and breakable element that serves as a safety seal. Deformation and / or breakage of the above elements is a sign of contamination.
Nevertheless, manufacturing this different type of bottle with a single body element requires a complex manufacturing process and high manufacturing costs.

  The main aim of the present invention is to provide liquid products, in particular pharmaceutical, medical or cosmetic, with a minimum requirement for safety in order to prevent or limit any potentially harmful use of the contained product. It is to provide an improved bottle of product.

Within this technical aim, another object of the present invention is to ensure a complete and sterile state of the product packed in the bottle.
Another object of the present invention is that it can be clearly and immediately known to know that the bottle has been opened.
Another object of the present invention is to respond to the above aim with a simple configuration.

The above-mentioned object is to provide a container body for storing a liquid product, in particular a medicinal, medical or cosmetic product, a dispensing port for the product formed at one end of the container body, and a tearable closing the dispensing port. A membrane, and a closure element that can be screwed or unscrewed at the one end of the container body and that has a cap and at least one perforation formed in the cap to perforate the membrane;
Maintenance means for maintaining the cap in a safe arrangement, wherein the perforation is arranged substantially away from the membrane and the closure element is screwed or unscrewed about an axis; All achieved by improved bottles of liquid products, in particular medicinal, medical and cosmetic products, characterized in that they comprise retaining means which allow the cap to rotate freely in at least one direction of rotation.
