Description

[Title established by the ISA under Rule 37.2] A FOOD SPOILAGE DETECTOR WITH GAS SENSOR
The present invention relates to a spoilage detector.
The date of expiry is stated by the producer on packaged food products. However, certain storage conditions should be provided for the food product to be usable until the stated date. It is not possible for the user to be informed whether such conditions have been provided until the package reaches him/her. In addition, the food product may spoil before the expiry date as a result of deformations likely to occur on the package. In order to eliminate such circumstances, as the expiry date on the package, the producers label an earlier date than the actual expiry date. In this case, the user does not consume the food product in a package not yet opened even though it has not actually spoiled due to being expired, and discards it, causing wastage. There are several apparatuses for the user to be informed about the condition of the food product in a package without opening the package. The solutions determining the condition of the food product by optical methods are not sufficiently reliable. The solutions detecting spoilage by perforating the package cannot inhibit gas exchange with the outer environment through the perforation, spoiling the food product while intending to detect spoilage.
State of the art U.S. patent application no. US5653941 defines a food product spoilage detector.
State of the art U.S. patent application no. US2009038374 defines a spoilage detector detecting spoilage without damaging the package.
State of the art U.S. patent application no. US2010171949 defines a spoilage detector optically detecting spoilage through the package.
The aim of the present invention is to realize a spoilage detector for packaged food products performing spoilage detecting without requiring opening the package.
The spoilage detector realized to achieve the aim of the present invention and disclosed in the first claim and the dependent claims, comprises a sensor detecting gas, a control unit analyzing the sensor data, and a spike enabling the gas/air in the package to be transmitted to the sensor by being stuck on the package. By means of the invention, the spoilage condition of food products in a package can be perceived without opening the package. A small hole is perforated on the package by the spike, and gas exchange with the outer environment is avoided as long as the spike is in the hole. The gas/air in the package is detected by means of the sensor, and is analyzed by the control unit, inspecting presence of the gasses to be released upon spoilage of the food product. By this, the user will be informed whether the packaged food product is spoiled without opening the package. For example, a food product package which has recently been expired can be controlled to understand whether spoilage has actually began, preventing discarding a good product.
In an embodiment of the invention, the spoilage detector comprises a movable spike having two positions in which it extends outwards from the body, and retracts into the body, respectively. With this embodiment, the spoilage detector is placed on the package, and the spike sticks on the package by extending outwards from the body. Gas exchange through the hole is avoided by the spoilage detector being placed on the food product package.
In another embodiment of the invention, the spoilage detector comprises an insulator between the body and the package comprising in its center a gap through which the spike can pass. The insulator ensures non-existence of inwards or outwards gas exchange through the hole opened by the spike by being seated on the package. With this embodiment, the user can observe the spoilage conditions of food products by placing one spoilage detector on each one of all food product packages.
In another embodiment of the invention, the spoilage detector comprises a wireless communication means, and the spoilage condition of the food products are transmitted to an external source such as a refrigerator or a smart phone. With this embodiment, the user can continuously monitor the spoilage condition of the packaged food products placed in a refrigerator.
In another embodiment of the invention, the control unit enables alerting the user audibly and/or visually upon detecting a gas indicating spoilage in a food product's package.
In different embodiments of the invention, the sensor enabling detecting gas is a sensor of a type capable of detecting ethylene or ammonia, or detecting VOC (volatile organic compounds). Detection is enabled for food products of varying types by using varying sensor types.
By means of the invention, the spoilage condition of packaged food products can be detected independent of their expiry dates and without requiring opening their packages, by only placing the spoilage detector on a package and the spike being stuck on the package. By means of the invention, without relying on the expiry date stated by the producer provided that certain requirements are met, the user can control whether a food product in a package has been spoiled without opening the package and without allowing the food product to be spoiled by avoiding gas exchange into the package from around the hole, thereby preventing food poisoning.
The spoilage detector realized to achieve the aims of the present invention is illustrated in the accompanying drawings, wherein:
Figure 1 is a schematic view of a spoilage detector.

  8. Wireless communication means
P. Package
G. Food product
The spoilage detector (1) of the invention suitable for use in measuring spoilage condition of packages food products (G), comprises a body (2), a sensor (3) provided in the body (2), enabling detecting the gasses in the package (P), a spike (4) provided in the body (2), whose one end is coupled to the sensor (3) and enabling with its other end perforating the package (P) and transmitting the air in the package (P) to the sensor (3), and a control unit (5) enabling determining the spoilage condition of the food product (G) by analyzing the data received from the sensor (3).
The package (P) is perforated by the spike (4) being stuck on the package (P), and the air/gasses in the package (P) are transmitted to the sensor (3) by means of the spike (4). By this, information about the spoilage condition of the food product (G) can be obtained by making a small perforation on the package (P) by means of the spike (4) without requiring opening the package (P). The sensor (3) is able to detect presence of gasses being released to the air in the package (P) upon spoilage of the food product (G), and the control unit (5) determines the spoilage condition of the food product (G) according to data it receives from the sensor (3).
In an embodiment of the invention, the spoilage detector (1) comprises a movable, retractable spike (4) and a switch (6) enabling moving the spike (4) on the body (2). In this embodiment, the body (2) is placed on the package (P) and the spike (4) is enabled to move and stick on the package (P) by means of the switch (6). Gas leakages likely to occur around the hole through which the spike (4) enters are intended to be avoided by placing the body (2) on the package (P). With this embodiment, upon placing the body (2) on the package (P) and being convinced that gas exchange will not be experienced, the switch (6) is used and the gaseous environment in the package (P) is enabled to be detected by the sensor (3) by means of the spike (4) perforating the package (P).
In another embodiment of the invention, the spoilage detector (1) comprises an insulator (7) providing the sealing between the body (2) and the package (P), having in its center a gap through which the spike (4) can pass. When the body (2) is placed on the package (P), the insulator (7) disposed on the surface of the body (2) placed on the package (P), provides the sealing by inhibiting gas exchange between the hole perforated by the spike (4) and the outer environment. Thus, the food product (G) is prevented from being spoiled due to interaction of the outer environment air with the package contents when the spoilage detector (1) is used and the package (P) is perforated by means of the spike (4).
In another embodiment of the invention, the spoilage detector (1) comprises a wireless communication means (8) provided in the body (2), and a control unit (5) enabling transmitting the spoilage condition information to an external source by means of the wireless communication means (8). The control unit (5) enables transmitting the spoilage condition of the food product (G) in the package (P) detected by means of the sensor (3), to an external source such as a display of a refrigerator or a smart phone by means of the wireless communication means (8). With this embodiment, the user places the spoilage detector (1) on a package (P) only once and is not required to touch the spoilage detector (1) to recheck, thereby preventing the hole in which the spike (4) is disposed from being enlarged due to movement, and inhibiting gas exchange with the outer environment.
In another embodiment of the invention, the control unit (5) enables audibly and/or visually reporting the spoilage condition to the user. The user places the spoilage detector (1) on the package (P) and enables the spike (4) to be stuck on the package (P), then the control unit (5) enables alerting the user upon detecting gasses which are released when the food product (G) begins getting spoiled. The user is thus enabled to monitor spoilage conditions of packaged food products by using multiple spoilage detectors (1).
In different embodiments of the invention, the sensor (3) is a sensor capable of detecting ethylene or ammonia, or of the VOC type. Using sensors (3) of varying types makes it possible to produce separate spoilage detectors (1) for varying food product (G) types, and moreover, using various sensors (3) within a single spoilage detector (1) makes using a single spoilage detector (1) sufficient for varying food product (G) types.
By means of the spoilage detector (1) of the invention, the spoilage condition of a food product (G) in a package (P) can be checked without requiring opening the package (P), and can be monitored until the package (P) is opened. Gas exchange through the hole opened when the spoilage detector (1) is placed on the package (P), is clearly inhibited by being able to produce the spoilage detector (1) in a compact size and by using the insulator (7), and the food product (G) is prevented from being spoiled due to the hole opened for inspection/analysis. With the invention, the package (P) remains as if not opened at all, and also the spoilage condition of the food product (G) is monitored in a reliable manner.
