Description

1 TARIFF 5 MODULAR SENSOR CARTRIDGE WITH COLOR CHANGE INDICATOR. SMART PACKAGING CLOSING MECHANISM Technological Field: This invention relates to closure mechanisms for resealing food packaging. related to and specifically ensuring the sealing of opened food packages, and also 10 Smart packaging sealing systems include sensor systems that can monitor internal atmospheric conditions of the package. It is related to the mechanism. State of the Art: When storing food products, after the packaging is opened, the products Various closure systems are used to ensure their protection. These systems are 15 especially dry foods, snack products, legumes and similar packaged foods They are commonly preferred for storage. Plastic clips, latching clips, Flexible ties containing wire and sliding closure elements are the most commonly used for this purpose. These are among the common solutions. These closure elements seal the mouth of the packaging. By mechanically compressing part of it, the product inside the package is directly exposed to the external environment. The aim is to reduce contact and thus extend the product's shelf life somewhat. Current packaging closure elements are essentially only mechanical closures. It has a function. After the packaging is sealed, something may happen inside the package. This is a mechanism that allows users to monitor atmospheric changes. It is not present in the systems. However, during the storage of food products, the package 25 Changes in the ambient conditions affect the freshness and spoilage of the product. It can provide important information about the process. In the process of storing food products. Changes occurring in the package atmosphere depend on various factors. Microorganisms can emerge, particularly with increases or decreases in ambient humidity. The gases produced as a result of these activities are 30% of those released during the ripening process of fruits and vegetables. Parameters such as ethylene gas and carbon dioxide accumulation indicate food spoilage. These are among the important indicators of the process. Such changes This is important for both maintaining product quality and consumer safety. It is of great importance. Within the scope of smart packaging technologies, some packages include gas or moisture indicators. 35 can be used. In such systems, the chemical is usually placed inside the package. or biochemical sensors, depending on changes in specific gas or humidity levels 2 It can show color changes. However, these systems are mostly packaging 5 These are structures integrated into the package during the production phase, and after the packaging is opened... Not suitable for resealable packages. Also, most of these sensors are fixed. It does not have a modular structure that can be changed according to different types of food. Therefore... In the current technical situation, systems capable of mechanically sealing the packaging inside the package it cannot monitor atmospheric conditions and smart packaging sensors detect opened packages 10 The inability to use it during the re-closure emerged as a significant drawback. It is emerging. This invention creates a packaging that allows opened food packaging to be resealed. development of the sealing mechanism and also the atmosphere inside the package The aim is to provide a system that allows these conditions to be monitored. This 15 within the scope of this, it can detect changes in gas or humidity inside the package and report these changes. a sensor system that visually informs the user through color changes The goal is to develop sensors suitable for different types of food. including replaceable and modular sensor cartridges that allow for its use The aim is also to create a packaging closure mechanism. 20 Explanation of the Figures Figure 1 - General perspective view of the intelligent packaging closure mechanism of the invention.

It has a sensor system that can monitor atmospheric changes that may occur inside the packaging. It relates to a smart packaging sealing mechanism. This mechanism basically consists of a top It includes a body (1) and a sub-body (2), and these two bodies form a hinge mechanism (3) 20 They are connected to each other via a clip-like, openable and closable structure. mechanically compressing the mouth of the packaging on the lower body (2) There is a compression surface (4) on which the packaging is located. to prevent the material from slipping and to provide a more secure closure There is a non-slip coating (5). There is also packaging on the lower body (2) 25 It contains a sensor chamber (6) that is in controlled contact with the atmosphere inside. and a sensor cartridge slot (7) in which the sensor cartridge can be placed The sensor cartridge (8) is placed inside the sensor cartridge slot (7), package colorimetric indicator materials that can detect atmospheric changes within them It contains 30 ingredients and may show color changes depending on gas or humidity variations. It consists of sensor compartments. Between the sensor cartridge (8) and the packaging interior atmosphere. In order to ensure controlled gas exchange, the cartridge must be in contact with the gases inside the package. part of it is covered with a gas permeable membrane (9) and the said membrane is a membrane It is fixed by the carrier frame (10). The sensor cartridge is protected from the external environment. For physical protection, a sensor guard is also installed on the sensor housing. 35 The cover (11) is located on the sensor cartridge and this cover protects the sensor cartridge from impact, dirt or mechanical damage. It helps to protect against contacts that occur on the sensor cartridge (8). 4 Clip 5 allows the user to easily observe the incoming color change. There is a transparent viewing window (12) on the outside of its body and this window isolated from the external environment thanks to the sealing gasket (13) located between the body and the outside environment It is fixed in this way. The sensor cartridge (8) is inside the sensor cartridge holder (7). It is fixed by means of the locking tab (14) and can be fixed by the user if necessary. It can be easily removed via the cartridge removal channel (15). Sensor housing (6) 10 inside to allow the gases inside the packaging to reach the sensor cartridge. Gas inlet channels (16) are located and these channels are connected to the sensor system of the package interior atmosphere. It enables the orientation of different atmospheres inside the sensor cartridge (8). These may include sensor compartments that can detect parameters such as humidity. It is arranged as compartment (17) and gas sensor compartment (18). The mechanical 15 of the clip body to increase durability and prevent deformation during use It contains body reinforcement ribs (19). The user's clip is practical There is a pull handle (20) on the upper body (1) so that it can be opened and closed. This lever allows the clip to be easily opened and the packaging to be tightened. It can be closed again. The sensor cartridge (8) is located inside the sensor cartridge holder (7) 20 The sensor cartridge is placed by sliding on the rail system (21) and this rail system It ensures the cartridge is securely fixed in the correct position and is easily accessible to the user. It allows for removal and replacement. The sensor housing (6) also contains a system that allows the gases inside the package to reach the sensor cartridge more effectively gas diffusion channel network (22) is located and this channel network contains atmospheric 25 in the packet. by directing the gases towards the sensor cartridge, the sensor system becomes more efficient. It contributes to a fast and precise response. The invention is a preferred choice. In the application, the sensor cartridge (8) may contain more than one sensor compartment. For this purpose, a multi-sensor compartment plate (23) is located inside the sensor cartridge and This plate contains sensor materials sensitive to different gas or humidity parameters. It can be installed. Thanks to this structure, the packaging closing mechanism in question... only by enabling the mechanical resealing of opened packages not only that, but the sensor also monitors the atmospheric conditions inside the packaging. by visually informing the user of color changes occurring on the cartridge It provides information about the storage conditions of the food product. 35
