Abstract
The present invention aims to provide a xenon flash lamp for sterilizing a container, which is suitable for the sterilization treatment of the inner surface of the container with a relatively narrow opening part and does not reduce the sterilization capability. The xenon flash lamp for sterilizing a container of the present invention includes two end portions of a light emitting tube formed of a cylindrical glass tube having a relatively large outer tube diameter, and the light emitting tube having an outer tube diameter smaller than the outer tube diameter of the two end portions of the light emitting tube, and is configured such that a part of the light emitting tube is at least partially bent so as to be inserted from an opening portion of the container.
Description
Technical Field
The present invention relates to a xenon flash lamp for sterilization of containers. More particularly, the present invention relates to a structure of a xenon flash lamp for sterilizing an inner surface of a container such as a polyester bottle (PET bottle) used as a container for food, drinking water, or the like, a preform for a polyester bottle before shaping, or a drinking cup.
Background
In the manufacture/processing of food or drinking water, it is important to reliably sterilize these containers. Due to the diversification of consumer demands, low chlorination of food and drinking water, elimination of preservatives, extension of a taste life, and the like are required, and thus, reliable sterilization treatment of containers is required.
Currently, sterilization techniques capable of performing sterilization in a non-heating/non-contact manner are being developed in place of or together with heat treatment and sterilization treatment based on a chemical agent. As such a non-heating/non-contact sterilization technique, a flash pulse sterilization process is attracting attention.
A xenon flash lamp was used in the flash pulse sterilization process. The xenon flash lamp is rich in ultraviolet rays with the effective sterilization wavelength of 200-300 nm in the light emission.
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 processed (such as a container) is small due to the pulse irradiation in a very short time.
On the other hand, the flash pulse sterilization process has a disadvantage that only a portion to which light can be irradiated can be sterilized. Therefore, even if the xenon flash lamp is used for irradiation 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 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 4 are those in which a part of the arc tube is inserted into the vessel, but there is no disclosure of an example in which the vessel insertion portion is relatively thin and the electrode sealing portion is relatively thick in terms of the tube diameter of the arc tube.
In general, a container such as a polyester bottle has an extremely fine shape in which the cross-sectional area of an opening portion (a bottle mouth portion screwed into a cap) of an upper end portion is smaller than the cross-sectional area of a body portion. Therefore, the thickness of the xenon flash lamp is limited by the inner diameter of the opening, and the entire arc tube needs to be made extremely thin.
When the arc tube is made thin, the temperature of the arc tube, particularly the electrode temperature, is higher than that of a conventional thick-diameter lamp. As a result, after the light irradiation time has elapsed, the electrode material scatters and adheres to the inner peripheral surface of the arc tube, so that the amount of light decreases at an early stage, and the lamp life is exhausted. Therefore, it is desired to realize a lamp having a long lamp life without such a phenomenon.
Accordingly, an object of the present invention is to provide a xenon flash lamp for sterilizing a container, which is suitable for sterilization treatment of an inner surface of a container having a relatively narrow opening portion without deteriorating sterilization capability.
Means for solving the problems
In view of the above object, one aspect of the xenon flash lamp for sterilizing a container according to the present invention is a xenon flash lamp that includes both ends of an arc tube made of a cylindrical glass tube having a relatively large outer tube diameter and an arc tube having an outer tube diameter smaller than the outer tube diameter of both ends of the arc tube, and that is configured such that a part of the arc tube is at least partially bent so as to be inserted into an opening of the container.
In the xenon flash lamp for sterilizing the container, the arc tube may be bent in a T-shape.
In the xenon flash lamp for sterilizing the container, the arc tube may be bent in a Y-shape or a shape of "ト" of japanese katakana.
In the xenon flash lamp for sterilizing the container, a thickness of a bent portion of the arc tube inserted into the container may be thicker than thicknesses of both end portions of the arc tube.
In the xenon flash lamp for sterilizing the container, the outer tube of the arc tube may have a diameter of 5mm to 6mm at a bent portion inserted into the container.
In the xenon flash lamp for sterilizing the container, a length of the bent portion inserted from the container opening portion into the container may be determined according to a depth of the container.
In the xenon flash lamp for vessel sterilization, the trigger line may be present along the outer peripheral surface of the arc tube.
In the xenon flash lamp for sterilizing a container, an anode electrode and a cathode electrode may be disposed to face each other at both ends of the arc tube.
In the xenon flash lamp for sterilizing a container, the center portion of the arc tube may be formed in a T-shape, and the tube diameter may be smaller than the tube diameters of both end portions.
In the xenon flash lamp for sterilizing the container, a part of the central portion may be formed in a U-shape, and the U-shaped portion may have a relatively small tube diameter and may be inserted into the container from the opening thereof.
In the xenon flash lamp for sterilizing the container, the U-shaped portion of the central portion may be inserted from the opening of the container to the vicinity of the bottom.
In the xenon flash lamp for sterilizing the container, a U-shaped portion in the central portion may be covered with a quartz sleeve covered with a teflon (registered trademark) film in order to prevent scattering of fragments when the lamp is broken or when glass is broken due to impact.
In the xenon flash lamp for sterilizing the container, both the one end portion in which the anode electrode is sealed and the other end portion in which the cathode electrode is sealed may be disposed outside the container.
In the xenon flash lamp for sterilizing the container, the size of the arc tube may be determined in accordance with the size of the container to manufacture the lamp when the container to be sterilized is known by the customer.

Detailed Description
Embodiments of a xenon flash lamp for sterilizing containers 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, first, a brief explanation will be given of a conventional xenon flash lamp so that the xenon flash lamp of the present embodiment can be easily understood.
[ 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 disposed 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 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 trigger line 108 is composed of a plurality of ring portion lines 108-1 that are respectively in close contact with the outer peripheral surface of the light-emitting tube 102 and surround the light-emitting tube, and a connecting portion line 108-2 that extends along the axis of the light-emitting tube and connects the plurality of ring portion lines 108-1.
The anode electrode 104a is formed of a tungsten rod having an anode large diameter portion 104a-2 formed by molding a distal end portion (light-emitting tube side) of the electrode lead rod 104a-1 into a cylindrical shape.
The end portion (light-emitting tube side) of the electrode lead rod 104b-1 is formed into a cylindrical shape to form a cathode large diameter portion 104b-2, and the cathode side electrode 104b is formed of a tungsten rod in which a cylindrical sintered body (also referred to as an "emitting portion") 104b-3 made of an electron radioactive material is fixed to the upper surface of the end portion of the cathode large diameter portion. The loop line 108-1 is positioned around the end of the emitting portion 104 b-3.
The electrode lead rods 104a-1 and 104b-1 are connected to leads 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. Although the trigger line is not shown in the figure to simplify the figure and make the figure clear, 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. In comparison with the conventional xenon flash lamp 110, the common point is that the anode electrode 4a and the cathode electrode 4b are disposed at both ends of the arc tube 2 so as to face each other.
However, the difference is that the central portion 2b of the arc tube 2 is formed in a T-shape, and the central portion 2b of the arc tube 2 is formed to be smaller in diameter than the tube diameters of the both end portions 2a, 2 c. Since a part of the central portion 2b is formed in a U-shape and the tube diameter of the U-shaped portion 2b-1 is made small, the container can be inserted from the opening portion thereof.
The difference is that the thickness of the central portion 2b of the arc tube 2 is thicker than the thickness of the end portions 2a and 2 c. By making the thickness of the central portion 2b relatively thick, breakage due to temperature rise caused by the small diameter is suppressed.
The two end portions 2a and 2c of the arc tube 2 are connected to each other with the same internal discharge space formed at the two end portions of the central portion 2 b. The anode electrode 4a and the cathode electrode 4b are each formed in a linear cylindrical shape along an axis connecting the centers of the two electrodes, and the ends are sealed. Similarly to the conventional xenon flash lamp 110, when the arc tube 2 is viewed from the drawing, the anode major diameter portion 4a-2 and the electrode lead 4a-1 are arranged at the left end portion 2a, and the emitter portion 4b-3, the cathode major diameter portion 4b-2 and the electrode lead 4b-1 are arranged at the opposite right end portion 2 c.
The specification of the T-shaped arc tube trial-produced by the present inventors is as follows. But is not limited thereto.
A luminous tube: the material is a common quartz tube
A central part: outer diameter
Thickness t 2.0mm
Two end parts: outer diameter

(mode of use of the Lamp)
Fig. 3 is a diagram illustrating a preform as a representative example of a container. Fig. 3 (a) shows the preform 12, fig. 3 (B) shows the polyester bottle 14 shaped from the preform, and fig. 3 (C) shows the commercial product 16 filled with the beverage in the polyester bottle. The preform 12 is an intermediate product of a stage before the expansion of the polyester bottle, and is widely used because it has a volume of 1/5 to 1/10 compared to the polyester bottle, and thus contributes to reduction of transportation cost and environmental load.
Although not shown, the preform 12 is heated and placed in a mother die having a polyester bottle shape, an extension rod is inserted into the preform from an opening, air is injected into the preform, the preform is molded into a bottle shape to obtain a polyester bottle 14, and then a beverage is filled into the bottle to obtain a product 16. Here, the shape of the opening (male screw forming portion) 12a, which is the mouth, is not changed from the beginning.
Fig. 4 is a diagram illustrating a state in which the inner surface of the preform 12 is subjected to the sterilization process using the xenon flash lamp 10a of the present embodiment. The U-shaped portion 2b-1 of the central portion 2b of the xenon flash lamp 10a is inserted from the container opening portion 12a to the vicinity of the bottom. 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 the 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 characterized in 1 st that a U-shaped portion 2b-1 of a central portion 2b is inserted from an opening portion 12a of a preform 12 to 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 (preform or the like), the lamp can be inserted near the bottom of the container, and 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 lead 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 lead 4a-1) is sealed are disposed outside the preform 12. Therefore, the dimensions of the elements constituting the electrode 4a (the cathode large-diameter portion 4a and the electrode lead 4a-1) and the elements constituting the electrode 4b (the emitter 4b-3, the anode large-diameter portion 4b and the electrode lead 4b) are not limited by the dimensions of the opening 12a of the preform 12, and conventional members can be used.
The specification of the T-shaped arc tube as originally manufactured by the present inventors is as follows. But is not limited thereto.
Opening of preform container:
length 80mm
A luminous tube: the material is a common quartz tube
A central part: outer diameter
Thickness t 2.0mm
Two end parts: outer diameter
Thickness t 1.0mm
Air pressure: xe gas 500torr
An electrode:
and (3) quartz sheathing: outer diameter
The operation conditions are as follows: lamp input energy 600J
Further, it is judged by trial production thereafter that the outer diameter of the central portion is preferable
(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, reference numeral 10a is a lamp, and reference numeral 8 is a trigger line. The lighting circuit 30 includes a commercial ac power supply 22, a charging high-voltage power supply circuit 24 that boosts and rectifies the commercial ac power supply 22, a charging/discharging capacitor 26 that accumulates an output of the charging high-voltage power supply circuit 24, and a waveform adjusting coil 28, and supplies a pulse voltage to the lamp 10. The trigger circuit 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.
(method of manufacturing a Lamp)
With regard to the method of manufacturing the xenon flash lamp 10a shown in fig. 2, the specification of the arc tube of the xenon flash lamp 10a is determined by the following matters.
(1) The diameter of the relatively thick tube at both ends 2a, 2b is set to the size of the electrode necessary for the sterilization process that can be sealed in the container. This allows the use of an electrode capable of irradiating light required for sterilization.
(2) The diameter (outer diameter D) of the relatively thin central portion inserted into the container is determined by the diameter (inner diameter D) of the opening of the container.
For example, D ═ 2D + α
Here, α: allowance of insertion
(3) The length L of the U-shaped portion 2b-1 of the arc tube central portion 2b is determined according to the depth L of the vessel.
For example, L is approximately equal to L
As described above, by considering (1) to (3), the xenon flash lamp 10a, which is a dedicated xenon flash lamp most suitable for sterilization, can be provided for each customer's container.
(advantages/features of the present embodiment)
The xenon flash lamp of this embodiment has the following advantages/features.
(1) The arc tube center part 2b is made small in diameter, and a part of the arc tube center part 2b is formed into a U-shaped part 2b-1, so that the vessel to be sterilized can be inserted from the opening of the vessel. This makes it possible to irradiate the entire inner surface of the container with pulsed light and perform a reliable sterilization process.
(2) When a user knows a container to be sterilized, the size of the light emitting tube is determined according to the size of the container, and the lamp can be manufactured. This makes it possible to provide a dedicated xenon flash lamp that is optimal for a customer's container.
(3) Since the both end portions 2a and 2c of the arc tube are positioned outside the container, the tube diameters of the both end portions 2a and 2c can be made larger than the conventional one without being influenced by the shape of the container opening 12 a. Therefore, the conventional electrode can be used as the electrode enclosed therein. As a result, the light emission intensity required for sterilization of the inner surface of the container can be ensured, and the life of the lamp can be ensured for the same time as that of the conventional lamp, so that a practical sterilization method can be provided in which the operating cost is kept low.
[ modifications and the like ]
The arc tube of the xenon flash lamp shown in fig. 2 and 3 is T-shaped when viewed as a whole. Various modifications to this shape are considered. Fig. 6 (a) and (B) are schematic diagrams showing a modification 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. 6B extends horizontally along the U-shaped portion 2B-1 of the arc tube central portion 2B and the other extends vertically, a combination thereof (one is in an oblique direction and the other is in a horizontal or vertical direction), and the like are considered.
In short, the U-shaped portion 2b-1 of the central portion 2b may be any shape as long as it is inserted into the container (for example, the preform 12) and both end portions 2a and 2c in which the electrode and the electrode lead are sealed are positioned outside the container.
[ conclusion ]
Although the embodiments of the xenon flash lamp for sterilizing containers according to the present invention have been described above, these are examples and do not limit the scope of the present invention at all. Those skilled in the art can easily add, delete, change, and improve the present embodiment and the like, which are included in the scope of the present invention.
