Description
Technical Field
The present invention relates to a xenon flash lamp for sterilization of containers. More specifically, the present invention relates to a xenon flash lamp structure for sterilizing the inner surface of a container such as a deep tray, cup, or bottle used as a container for food, drinking water, or the like.
Background
In a manufacturing plant for food or drinking water, it is important to reliably sterilize these containers. Due to the diversification of consumer demands, low chlorination of food or drinking water, elimination of preservatives, prolongation of shelf life, and the like, reliable sterilization treatment of containers is required.
At present, development of sterilization techniques capable of performing sterilization without heating or in contact with heat instead of or in combination with heat treatment or sterilization treatment using chemicals has been advanced. Flash pulse sterilization is attracting attention as such a non-heating, non-contact sterilization technique.
In the flash pulse sterilization process, a xenon flash lamp is used. The xenon flash lamp emits light, and contains ultraviolet rays having a wavelength of 200 to 300nm, which are effective for sterilization, in a large amount.
The flash sterilization treatment using the xenon flash lamp has the following advantages: the sterilization effect is strong, pulse control of light emission is easy, no residue is generated due to non-contact, and the influence on the object to be treated (container and the like) is small due to pulse irradiation in a very short time.
In contrast, the flash pulse sterilization process has a disadvantage that only a portion capable of irradiating light can be sterilized. Therefore, even if the xenon flash lamp is irradiated from the outside of the container, the light may not sufficiently reach a part of the inner surface of the container (for example, the bottom surface of the container or the shoulder portion of the bottle shape having a small opening), and sufficient sterilization may not be performed.
Conventionally, a method of sterilizing a container by inserting a part of a xenon flash lamp, which will be described below, into the container and performing pulse irradiation from the inside of the container has been proposed.

Disclosure of Invention
Problems to be solved by the invention
The lamps disclosed in patent documents 1 to 3 have a part of the arc tube inserted into the vessel. However, these patent documents do not describe any problem occurring in the container insertion portion of the arc tube and any limitation on the glass strength for solving the problem.
When a light-emitting tube in which a container insertion portion of the light-emitting tube is formed in a U-shape is tried to be manufactured, devitrification (a phenomenon that glass is crystallized and becomes brittle) occurs in an inner surface of the light-emitting tube at an inner side of a lowermost portion of the U-shape in a bent portion at a lower end, and further, a phenomenon that a hole is leaked occurs after a lighting time elapses. That is, the lamp life is shorter than that of a conventional straight tube xenon flash lamp. The mechanical strength of the inside of the U-shaped bent portion is insufficient, and the bent portion is damaged by a temperature rise at the time of lighting.
Accordingly, an object of the present invention is to provide a xenon flash lamp having a U-shaped container internal insertion portion and having a lamp life equivalent to that of a conventional straight tube lamp.
Means for solving the problems
In view of the above object, the xenon flash lamp of the present invention is a xenon flash lamp having an arc tube composed of a cylindrical glass tube,

the thickness t2[ mm ] of the U-shaped straight section Us is in the range of 0.4. ltoreq. t 2. ltoreq.2.0.
In the xenon flash lamp, the thickness t1[ mm ] of the inner wall of the U-shaped bent portion and the thickness t2[ mm ] of the straight portion Us may be in the range of 0.8. ltoreq. t1 and t 2. ltoreq.2.0.
Further, in the xenon flash lamp, the arc tube may be bent in a T-shape.
Further, in the xenon flash lamp, the light emitting tube may be bent in a Y-shape or a japanese katakana "ト" shape.
In the xenon flash lamp, a length of the bent portion inserted from the opening of the container into the container may be determined according to a depth of the container.
Further, in the xenon flash lamp, a trigger line may be present along an outer peripheral surface of the arc tube.
Further, in the xenon flash lamp, a central portion of the arc tube may be formed in a U-shape.
In the xenon flash lamp, the left end portion, the center portion, and the right end portion of the arc tube may be connected to form a discharge space having the same outer diameter, both end portions may be sealed, an anode electrode may be disposed at one end portion, and a cathode electrode may be disposed at the other end portion.

Detailed Description
Embodiments of a xenon flash lamp for sterilization of a container according to the present invention will be described in detail below with reference to the accompanying drawings. In the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted.
The xenon flash lamp of the present embodiment is characterized by the external appearance shape of the lamp, compared to the conventional xenon flash lamp. Therefore, in order to easily understand the xenon flash lamp of the present embodiment, first, a conventional xenon flash lamp will be briefly described.
[ existing xenon flash lamp ]
Fig. 1 is a diagram illustrating a conventional xenon flash lamp. The conventional xenon flash lamp 110 has a structure in which an anode electrode 104a and a cathode electrode 104b are arranged to face each other at both ends of an arc tube 102 in which xenon gas as a rare gas is sealed. The arc tube 102 is made of quartz glass having a high ultraviolet transmittance, and is formed into a linear cylindrical shape having a constant thickness and sealed at both ends.
A trigger line (also referred to as an "auxiliary electrode for starting") 108 is arranged along the outer peripheral surface of the light-emitting tube 102. The ignition wire 108 is constituted by a plurality of ring portion wires 108-1 which are respectively brought into close contact with the outer peripheral surface of the light emitting tube 102 and surround the light emitting tube, and a connecting portion wire 108-2 which extends along the axis of the light emitting tube and connects the plurality of ring portion wires 108-1.
The anode electrode 104a is formed of a tungsten rod having an anode large diameter portion 104a-2, and the anode large diameter portion 104a-2 is formed by molding a distal end portion (light-emitting tube side) of the electrode guide rod 104a-1 into a cylindrical shape.
The cathode 104b is formed by molding the end portion (light-emitting tube side) of the electrode guide rod 104b-1 into a cylindrical shape to form a cathode large-diameter portion 104b-2, and the cathode 104b is formed by a tungsten rod having a cylindrical sintered body (also referred to as an "emitter portion") 104b-3 made of an electron radioactive material fixed to the upper surface of the end portion of the cathode large-diameter portion. The loop wire 108-1 is positioned around the end of the emitter pole segment 104 b-3.
The electrode lead rods 104a-1 and 104b-1 are connected to lead wires 103a and 103b on the opposite sides of the light emitting tube, respectively.
[ xenon flash lamp of the present example ]
(Lamp shape)
Fig. 2 is a diagram illustrating a xenon flash lamp 10a of the present embodiment. Note that, although the trigger line is not shown in order to simplify the drawing for clarity, the trigger line actually exists along the outer peripheral surface of the arc tube 2 as in fig. 1.
Differences from the conventional xenon flash lamp 110 shown in fig. 1 will be mainly described. The anode electrode 4a and the cathode electrode 4b are disposed to face each other at both ends of the arc tube 2 in common as compared with the conventional xenon flash lamp 110, but are different from each other in that the central portion 2b of the arc tube 2 is formed in a U-shape. The U-shaped portion 2b-1 is inserted into the container from the opening thereof.
The left end portion 2a, the center portion 2b, and the right end portion 2c of the arc tube 2 are connected to form a discharge space having the same outer diameter, and both end portions are sealed. Like the conventional xenon flash lamp 110, an anode diameter portion 4a-2 and an electrode guide rod 4a-1 are disposed at a left end portion 2a of the arc tube 2, and an emitter portion 4b-3, a cathode diameter portion 4b-2 and an electrode guide rod 4b-1 are disposed at an opposite right end portion 2 c.
The specification of the U-shaped arc tube tried out by the present inventors is as follows. However, the present invention is not limited thereto.

(mode of use of the Lamp)
Fig. 3 is a diagram showing an example of a container to be subjected to sterilization processing.
Fig. 4 is a diagram illustrating a state in which the xenon flash lamp 10a of the present embodiment is used to sterilize the inner surface of the container 12. The U-shaped portion 2b-1 of the central portion 2b of the xenon flash lamp 10a is deeply inserted from the container opening portion 12a into the inside. The U-shaped portion 2b-1 of the central portion 2b is covered with a quartz cover 6 covered with a Teflon (registered trademark) film. The quartz envelope 6 serves to prevent scattering of fragments in the event of breakage of the lamp or of breakage of the glass caused by impact.
The xenon flash lamp 10a is first characterized in that a U-shaped portion 2b-1 of the central portion 2b is inserted from the opening portion 12a of the container 12 into the inside. By determining the length of the U-shaped portion 2b-1 of the lamp 10a in accordance with the depth of the container 12, the entire inner surface of the container can be directly irradiated with light to perform sterilization.
On the other hand, the left end portion 2a in which the anode electrode 4a (anode large diameter portion 4a, electrode guide rod 4a-1) is sealed and the right end portion 2c in which the cathode electrode 4b (emitter 4b-3, cathode large diameter portion 4a, electrode guide rod 4a-1) is sealed are disposed outside the container 12.
The specification of the U-shaped arc tube tried out by the present inventors is as follows. However, the present invention is not limited thereto.

The operation conditions are as follows: lamp input energy 600J
(mechanical Strength of luminous tube)
When a light emitting tube having a U-shaped central portion is first manufactured and lighted, the inner surface of the light emitting tube on the inner side of the lowermost portion of the U-shape is devitrified, and further, after the lighting time has elapsed, a hole leakage phenomenon occurs. Fig. 5 is a photograph showing holes in which devitrification and leakage occur at the U-shaped bent portion of the arc tube. Fig. 5 (a) is a diagram showing an X-ray photograph, fig. 5 (B) is a diagram showing an external appearance photograph of the lamp after lighting, and fig. 5 (C) is a diagram showing a photograph of a hole which is devitrified and leaked.
The present inventors examined the positions of holes for devitrification and leakage and found that the holes were formed in the U-shaped bent portion. The glass strength of this portion is considered to be weak.
Therefore, the glass thickness of the U-shaped portion 2b-1 is controlled to ensure the glass strength. Several test pieces having different glass thicknesses were produced, and the optimum range of the inner wall thickness t2 of the bent portion Ub and the optimum range of the wall thickness t2 of the straight portion Us were determined. Table 1 shows the experimental results thereof. The outer diameter D of the arc tube used in the experiment was 10.0 mm.
[ Table 1]
Table 1: optimum ranges of the inner wall thickness t2 of the curved portion Ub and the wall thickness t2 of the linear portion Us
As shown in Table 1, the inner wall thickness t1[ mm ] of the bent portion Ub does not cause devitrification and leakage in the range of 0.8. ltoreq. t 1. ltoreq.2.5. However, when the glass wall thickness is thinner than this range, t1 < 0.6, devitrification and leakage occur. On the other hand, the thickness t2[ mm ] of the straight section Us is in the range of 0.4. ltoreq. t 2. ltoreq.2.0, and a sufficient amount of light can be secured. However, when the glass wall thickness is greater than 2.5 < t2, the glass becomes dark and the light quantity is insufficient.
Therefore, when t1 and t2 are not separately managed, as a comprehensive evaluation, the ranges in which sufficient light quantity can be secured without causing devitrification and leakage are 0.8. ltoreq. t1 and t 2. ltoreq.2.0.
(Lighting circuit of xenon flash lamp)
Fig. 5 is a diagram illustrating an example of the xenon flash lamp lighting circuit 30 shown in fig. 2. Here, the symbol 10a is a lamp, and the symbol 8 is a trigger line. The lighting circuit 30 includes: a commercial alternating-current power supply 22; a charging high-voltage power supply circuit 24 that boosts and rectifies the commercial ac power supply; a charge/discharge capacitor 26 for storing an output of the charge high-voltage power supply circuit 24; and a waveform adjusting coil 28 for supplying a pulse voltage to the lamp 10. The trigger control circuit further includes an external trigger generating circuit 32 for starting and a pulse booster transformer 34 for boosting the trigger pulse and sending it to the trigger line 8.
(advantages and features of the present embodiment)
The xenon flash lamp of this embodiment has the following advantages and features.
(1) The arc tube center part 2b of the xenon flash lamp is formed into a U-shaped part 2b-1, the inner wall thickness t1[ mm ] of the bent part is in the range of 0.8 to t1 to 2.5, and the wall thickness t2[ mm ] of the U-shaped straight part Us is in the range of 0.4 to t2 to 2.0, so that devitrification and leakage do not occur, and a sufficient amount of light can be secured.
(2) When the thickness t1[ mm ] of the inner wall of the curved portion Ub and the thickness t2[ mm ] of the straight portion Us of the U-shaped portion 2b-1 of the arc tube of the xenon flash lamp are in the ranges of 0.8. ltoreq. t1 and t 2. ltoreq.2.0 without separately managing t1 and t2, devitrification and leakage do not occur, and a sufficient amount of light can be secured.
(3) The length of the portion bent in a shape insertable from the container opening to the inside can be determined according to the depth of the container, and ultraviolet rays can be irradiated to the inner peripheral surface and the bottom of the container.
[ modifications and the like ]
The arc tube of the xenon flash lamp shown in fig. 2 and 4 has a T-shape as a whole. Various modifications of this shape are conceivable. Fig. 7 (a) and (B) are schematic diagrams showing a modified example of the xenon flash lamp of the present embodiment. For example, a Y-shape shown in fig. 6 a, a japanese katakana "ト" shape in which one of the two end portions 2a and 2c shown in fig. 7B extends in the horizontal direction in the arc tube central portion 2B and the other extends in the vertical direction, and a combination thereof (one is in an oblique direction and the other is in a horizontal or vertical direction), and the like.
