Description
本發明係有關樹脂製容器帶電量之測定,尤其係關於一種測定樹脂製容器之內表面與外表面之電位差的測定裝置。The present invention relates to the measurement of the charge amount of a resin container, and more particularly to a measuring device for measuring the potential difference between the inner surface and the outer surface of a resin container.
自先前以來,樹脂製容器之帶電已為人所知。例如,如專利文獻1般,於使藉由容器搬送裝置所搬送之樹脂製容器通過電子束照射裝置之前面側的期間,自電子束照射裝置之照射窗照射電子束而進行殺菌時,如圖4所示,會變成如下之狀態:負電荷滯留於樹脂製容器2之壁體內部,且具有正電荷之離子附著於樹脂製容器2外側表面的外表面2a與內側表面的內表面2b上。尤其,於該圖4之狀態下,會變成直接受到電子束的照射之外表面2a側一方之電位高於內表面2b側的狀態(以C1表示外表面2a側之電位,以C2表示內表面2b側之電位),而於外表面2a與內表面2b之間產生電位差V。The charging of resin containers has been known since the beginning. For example, in the case where the resin container conveyed by the container conveying device passes through the front side of the electron beam irradiation device, the electron beam is irradiated from the irradiation window of the electron beam irradiation device to sterilize, as shown in FIG. As shown in FIG. 4, the negative electric charge is retained in the inside of the wall body of the resin container 2, and ions having a positive electric charge adhere to the outer surface 2a of the outer surface of the resin container 2 and the inner surface 2b of the inner side surface. In particular, in the state of FIG. 4, the potential on the side of the surface 2a side directly irradiated with the electron beam is higher than the side of the inner surface 2b (the potential on the outer surface 2a side is indicated by C1, and the inner surface is represented by C2). A potential difference V is generated between the outer surface 2a and the inner surface 2b.

若如上述般使電荷滯留於樹脂製容器之壁面內部,則滯留於外側表面與內側表面的電荷成為不同,而於內表面與外表面之間會產生電位差。若使手或口接觸該種狀態之樹脂製容器,則會有產生靜電之情形。因此,有必要測定樹脂製容器之壁體內外表面之電位差以何種方式存在。When the electric charge is retained inside the wall surface of the resin container as described above, the electric charge remaining on the outer surface and the inner surface is different, and a potential difference is generated between the inner surface and the outer surface. If the hand or the mouth is brought into contact with the resin container in this state, static electricity may be generated. Therefore, it is necessary to determine the manner in which the potential difference between the inner and outer surfaces of the resin container wall exists.

又,第2發明係如上述第1發明中,與上述電壓測定手段並聯地配置有電阻。According to a second aspect of the invention, in the first aspect of the invention, the resistor is disposed in parallel with the voltage measuring means.
進而,第3發明之測定方法係測定樹脂製容器之內表面與外表面之電位差的測定方法,其特徵在於:使樹脂製容器之內表面與外表面分別與導電性介質接觸後,形成將接觸內表面之導電性介質、與接觸外表面之導電性介質加以連接的回路,並藉由測定於該回路內流動之電壓,而測定樹脂製容器之內表面與外表面之電位差。Further, the measuring method according to the third aspect of the invention is a method for measuring a potential difference between an inner surface and an outer surface of a resin container, wherein the inner surface and the outer surface of the resin container are brought into contact with a conductive medium to form a contact. A conductive medium on the inner surface and a circuit connected to the conductive medium contacting the outer surface, and measuring the voltage flowing in the circuit, the potential difference between the inner surface and the outer surface of the resin container is measured.
本發明之測定裝置以如下之簡單構成,可具有準確地測定樹脂製容器之壁體的內表面側與外表面側之電位差的優點;該構成係將填充有液體之樹脂製容器配置於充滿液體之容器內,且向兩容器內之液體中分別插入電極,再形成連接兩電極並藉由開關而可開閉之電路,且於該電路內連接有測定手段。The measuring apparatus of the present invention has the following advantages, and has an advantage of accurately measuring the potential difference between the inner surface side and the outer surface side of the wall of the resin container; this configuration is to dispose the resin-filled container filled with the liquid in the liquid filling In the container, electrodes are inserted into the liquids in the two containers, and a circuit that connects the two electrodes and can be opened and closed by a switch is formed, and a measuring means is connected to the circuit.
設置於內部充滿液體之狀態的容器(container),且將內部填充有飲料等液體之樹脂製容器配置於上述容器之液體內。使第1電極插入至填充於樹脂製容器內之液體中,同時,使第2電極插入至容器內之液體中,而形成連接該等第1電極與第2電極之電路,藉由開關而可對其進行開閉。使示波器連接至該電路而測定回路內之電壓。藉由該種簡單構成,則可以簡單操作而實現測定樹脂製容器之內表面與外表面間的電位差之目的。A container provided in a state in which the inside is filled with a liquid, and a resin container in which a liquid such as a beverage is filled inside is placed in the liquid of the container. The first electrode is inserted into the liquid filled in the resin container, and the second electrode is inserted into the liquid in the container to form a circuit for connecting the first electrode and the second electrode, and the switch can be used. Open and close it. Connect the oscilloscope to the circuit to determine the voltage inside the loop. According to this simple configuration, the purpose of measuring the potential difference between the inner surface and the outer surface of the resin container can be achieved by a simple operation.
以下,藉由圖式所示之實施例來說明本發明。樹脂製容器2因某種操作而導致電荷滯留於其壁體上,並且該電荷存在偏差,例如,在樹脂製容器2之外表面2a側與內表面2b側之間產生有電位差。此實施例之測定裝置係測定該電位差之裝置。Hereinafter, the present invention will be described by way of embodiments shown in the drawings. The resin container 2 causes electric charges to remain on the wall body due to a certain operation, and the electric charge is deviated. For example, a potential difference is generated between the outer surface 2a side and the inner surface 2b side of the resin container 2 . The measuring device of this embodiment is a device for measuring the potential difference.
此測定裝置包括:樹脂製之基座4;金屬製之容器8,其載置於該基座4上,且內部充滿液體6;樹脂製容器2,其內部填充有液體10,且配置於上述容器8內所充滿之液體6中;第1電極12,其插入至填充於樹脂製容器2內之液體10中;第2電極14,其插入至充滿於上述容器8內之液體6中;電路18,其使該等第1電極12與第2電極14連通,並且其一端接地16;以及作為電壓測定手段之示波器20,其連接至該電路18,並測定電路18內之電壓。該電路18係藉由開關22而進行開閉。進而,其具有與連接至該電路18之示波器20並聯連接之電阻24。The measuring device includes: a resin base 4; a metal container 8 placed on the base 4 and filled with a liquid 6 therein; and a resin container 2 filled with a liquid 10 and disposed in the above The liquid 6 filled in the container 8; the first electrode 12 is inserted into the liquid 10 filled in the resin container 2; the second electrode 14 is inserted into the liquid 6 filled in the container 8; 18. The first electrode 12 and the second electrode 14 are connected to each other, and one end thereof is grounded to 16; and an oscilloscope 20 as a voltage measuring means is connected to the circuit 18, and the voltage in the circuit 18 is measured. The circuit 18 is opened and closed by the switch 22. Further, it has a resistor 24 connected in parallel with the oscilloscope 20 connected to the circuit 18.
若使上述測定裝置之開關22開啟(圖2所示的狀態),則電路18被連接,而填充於樹脂製容器2內之液體10所接觸之樹脂製容器2的內表面2b側、與充滿於金屬容器8內之液體6所接觸之樹脂製容器2的外表面2a側之電位差(電壓)則被顯示於上述示波器20中。圖3係顯示於示波器20中之電壓波形,而被測定樹脂製容器2壁體的內表面2b側與外表面2a側之電位差。又,如該圖3所示,藉由連接電路18,不均衡地滯留於樹脂製容器2之內外表面2a、2b上的電荷則流動而變得大致相等,電位差則消失(圖2之符號0表示測定前之電位差V(參照圖1)已消失)。When the switch 22 of the measuring device is turned on (the state shown in FIG. 2), the circuit 18 is connected, and the inner surface 2b side of the resin container 2 which is filled in the resin container 2 is filled and filled. A potential difference (voltage) on the outer surface 2a side of the resin container 2 in contact with the liquid 6 in the metal container 8 is displayed in the above-described oscilloscope 20. Fig. 3 shows the voltage waveform of the oscilloscope 20, and the potential difference between the inner surface 2b side and the outer surface 2a side of the wall of the resin container 2 is measured. Further, as shown in FIG. 3, the electric charge which is unevenly accumulated on the inner and outer surfaces 2a and 2b of the resin container 2 flows by the connection circuit 18 and becomes substantially equal, and the potential difference disappears (symbol 0 of FIG. 2). It indicates that the potential difference V (refer to FIG. 1) before the measurement has disappeared.
於藉由該測定裝置而測定樹脂製容器2之電位差之情形下,當使開關22開啟時,由於電位差瞬間地下降,故難以進行測定,因此於該實施例中介存有電阻24而使反應速度減慢。又,因介由電阻24,故根據電阻值可求出電流值,且藉由測定該電流值須多長時間流動亦可算出電荷量。When the potential difference of the resin container 2 is measured by the measuring device, when the switch 22 is turned on, the potential difference is instantaneously lowered, so that measurement is difficult. Therefore, in this embodiment, the resistor 24 is interposed to make the reaction speed. Slow down. Further, since the resistor 24 is interposed, the current value can be obtained from the resistance value, and the amount of charge can be calculated by measuring how long the current value needs to flow.
再者,於上述實施例中,將容器8設定為鐵或不鏽鋼等金 屬製者,但其並不限定於金屬製者,亦可為樹脂製等。又,於金屬製容器8之情形時,如將電極(第2電極14)連接到充滿於內部之液體6與容器8之任一者即可,但於樹脂製之容器8之情形時,則第2電極14必需連接至內部之液體。若放入至容器8內之液體6及填充於樹脂製容器2內之液體10為具有某種程度之導電性的液體,則可使用任何液體。又,載置上述容器8之基座4亦可被省略。Furthermore, in the above embodiment, the container 8 is set to gold such as iron or stainless steel. It is a circulatory person, but it is not limited to a metal one, and may be made of a resin or the like. Further, in the case of the metal container 8, the electrode (the second electrode 14) may be connected to any of the liquid 6 and the container 8 filled in the interior, but in the case of the resin container 8, The second electrode 14 must be connected to the liquid inside. If the liquid 6 placed in the container 8 and the liquid 10 filled in the resin container 2 are liquids having a certain degree of conductivity, any liquid can be used. Further, the susceptor 4 on which the container 8 is placed may be omitted.
於上述實施例中,雖將進行電路18之連通阻斷的開關22設置於圖示之位置,但亦可將開關設置於例如圖1中由符號A所示之位置。然而,當將開關設置於該位置時,於容器為樹脂製之情形時雖並無問題,但如為金屬製之容器之情形時,若直接設置於地面上,則使樹脂製容器內與容器連通,故其必需設置非導電性之基座。再者,於該實施例中,雖使用水等液體6、10作為導電性介質,但亦可使用例如銅或鋁之薄膜作為該種液體以外之導電性介質。即使將該等薄膜貼著於樹脂製容器2之內表面與外表面,其亦可與上述實施例同様地測定電位差。In the above embodiment, the switch 22 for blocking the communication of the circuit 18 is provided at the position shown in the figure, but the switch may be provided, for example, at the position indicated by the symbol A in Fig. 1. However, when the switch is placed at this position, there is no problem in the case where the container is made of a resin, but in the case of a metal container, if it is directly placed on the floor, the inside of the resin container and the container are made. Connected, so it is necessary to set a non-conductive base. Further, in the embodiment, the liquids 6, 10 such as water are used as the conductive medium, but a film of copper or aluminum, for example, may be used as the conductive medium other than the liquid. Even if the films are attached to the inner surface and the outer surface of the resin container 2, the potential difference can be measured in the same manner as in the above embodiment.
