DETAILED DESCRIPTION OF THE INVENTION
A first example of the present invention will be described with reference to FIGS.
[0019]
In the figure, reference numeral 3 denotes an exterior container according to the present invention, which is a bottomed cylindrical synthetic resin injection molded product having an opening 2 at its upper end, which stores and holds the heating element filling container 1 indicated by a one-dot chain line in the figure. is there.
[0020]
A locking portion 4 protruding inward is provided on the upper side wall of the outer container 3. The locking portion 4 locks the upper portion of the heating element filling container 1 when the heating element filling container 1 is pushed into the predetermined position from the opening 2. That is, the heating element filling container 1 is pushed in from the opening 2 so as to elastically slightly expand the outer container 3. When the heating element filling container 1 is pushed to a predetermined position, the outer container 3 is elastically restored, and accordingly, the locking portion 4 locks the upper portion of the heating element filling container 1.
[0021]
The locking portions 4 in this example are provided at two opposite locations. The locking portions 4 can be provided, for example, at three locations at equal intervals in the circumferential direction of the outer container 3 or at four locations facing each other in the cross direction. When the body-filling container 1 is taken out, it is difficult to take out unless a large number of places are folded down. Further, although one locking portion 4 in this example is provided at one place, a plurality (generally 2 to 5) of locking portions 4 are provided at one place according to the diameter of the outer container. Is preferably provided in series in the circumferential direction because more reliable locking can be easily obtained.
[0022]
A cutting line 5 is formed at a position sandwiching the locking portion 4 above the side wall. The illustrated cutting line 5 is a slit, and an uncut connecting portion 6 is left at the upper end. This cutting line 5 is intended to be able to fold down the portion together with the locking portion 4 by pushing the upper portion of the side wall sandwiched therebetween outward. If the upper portion of the side wall sandwiched between the cutting lines 5 is folded outward, the locking of the upper portion of the heating element filling container 1 by the locking portion 4 can be released, and the heating element filling container 1 can be easily taken out.
[0023]
The cutting line 5 can be constituted by, for example, intermittent cuts, line-shaped grooves (for example, V-shaped grooves), or the like. However, the cutting line 5 is not required to easily bend the upper portion of the side wall sandwiched between them, and to easily fold the portion outward. It is preferable that the slit is formed by leaving the connecting portion 6 as described above. That is, in the case of the slit leaving the connecting portion 6, there is an advantage that the strength adjustment can be easily performed by adjusting the size, thickness, shape, or the like of the connecting portion 6 according to the constituent material of the outer container 3. Further, the connecting portion 6 can be left not in the upper end as shown in the figure but in the middle portion or in a plurality of places, and the intensity adjustment can be performed by adjusting the position and number.
[0024]
The cutting line 5 suffices to be provided at a position sandwiching the locking portion 4, that is, vertically on both sides of the locking portion 4, but depending on the thickness and material of the side wall of the exterior container 3, It can also be provided in the direction. The cutting line 5 provided in the lower circumferential direction of the locking part 4 may be a slit leaving the connecting part 6 as described above. However, the strength of the upper part of the side wall sandwiched between the vertical cutting lines 5 is maintained. For example, it is preferable to configure with intermittent cuts or line-shaped grooves.
[0025]
The cutting line 5 does not have to be formed with respect to all the locking portions 4, and only when a portion of the locking portions 4 is provided as long as the heating element filling container 1 can be taken out. It is good also as forming. For example, in this example, the cutting line 5 can be formed only for one of the locking portions 4. However, in this example as well, the release of the upper portion of the heating element filling container 1 by the both locking portions 4 is easier to remove, so the cutting lines 5 are connected to all the locking portions 4. It is preferable to form it.
[0026]
Reinforcing ribs 7 extending from the bottom surface in the longitudinal direction of the side wall inner surface are formed immediately below the locking portion 4 with a slight gap between the locking portion 4 and the locking portion 4. The reinforcing rib 7 is for preventing the side wall portion from being deformed when the side wall upper portion sandwiched between the cutting lines 5 is folded outward. The illustrated reinforcing rib 7 protrudes inward to the position where the inner end face comes into contact with the peripheral side surface of the heating element filling container 1 pushed in from the opening 2, and inside the outer container 3 of the heating element filling container 1. It is possible to prevent play in the horizontal direction.
[0027]
The reinforcing rib 7 can be omitted depending on the strength of the side wall. Further, the inward protruding amount can be reduced so that the inner end surface is located away from the outer peripheral surface of the heating element filling container 1 or can be formed continuously from the locking portion 4. In particular, when continuous from the locking portion 4, the strength of the upper portion of the side wall sandwiched between the cutting lines 5 can be adjusted by adjusting the amount of inward protrusion.
[0028]
Reinforcing ribs 8 extending from the bottom surface in the vertical direction of the side wall inner surface are formed on the outer side of the cutting line 5 (on the side of the anti-locking portion 4) and at a position shifted by about 90 degrees in the circumferential direction from the position of the locking portion 4. Yes. The upper portion of the reinforcing rib 8 protrudes inward to a position where the inner end surface (top surface) is in contact with the peripheral side surface of the heating element filling container 1 pushed through the opening 2. It is possible to prevent lateral play in the container 3. Moreover, the lower part of each reinforcing rib 8 protrudes further inward than the upper part, and the support part 9 is formed as a step part on which the bottom peripheral part of the heating element filling container 1 is hung. In other words, the heating element filling container 1 is pushed from the opening 2 to a position where the bottom part comes into contact with the support part 9 that is the stepped part, and is accommodated in a state of being sandwiched between the support part 9 and the locking part 4. Is.
[0029]
The reinforcing rib 8 also has a side wall deformation preventing function. In particular, when the reinforcing rib 8 is provided outside the cutting line 5, as in the case of the reinforcing rib 7, the side wall portion is prevented from being deformed when the side wall upper portion sandwiched between the cutting lines 5 is folded outward. be able to. Further, the number and position of the reinforcing ribs 8 may be appropriately selected according to the strength of the side wall, and may be omitted depending on circumstances. In this case, a support portion 9 as shown in FIG. 7 or FIG.
[0030]
FIG. 4 shows an example in which the heating element filling container 1 is stored and held in the exterior container 3 described in FIGS. 1 to 3. The heating element filling container 1 is hung on the support portion 9 at the bottom periphery. And the upper surface is locked by the locking portion 4 and is stored and held while being sandwiched between the support portion 9 and the locking portion 4. Moreover, the heating element filling container 1 exposes the top surface through the opening 2 of the outer container 3 that becomes a transpiration port of the component when, for example, a smoke agent or a fumigant is filled, and the outer container 3. It is stored and held with a gap between and.
[0031]
In order to take out the heating element filling container 1 in the above-mentioned storage state from the exterior container 3 after use, as shown in FIG. If the lock is released, it can be easily taken out. Therefore, the exterior container 3 and the heating element filling container 1 can be separated and discarded easily.
[0032]
FIG. 6 shows another example of the case where the heating element filling container 1 is housed and held in the exterior container 3 described with reference to FIGS. 1 to 3, and the heating element filling container 1 is a heat insulating cylinder on the outer periphery of the container body 1a. 1b is fitted. The heat insulating cylinder 1b is usually made of cardboard and suppresses the release of heat from the container body 1a. Particularly in this example, the locking portion 4 locks the upper surface of the heat insulating cylinder 1b. If it does in this way, it will become difficult to damage the latching | locking part 4 by the heat_generation | fever at the time of use. In the illustrated example, the lower end of the heat insulating cylinder 1b is substantially aligned with the lower surface of the container main body 1a. However, the lower end of the heat insulating cylinder 1b protrudes slightly below the lower surface of the container main body 1a. It becomes easy to prevent damage to the support portion 9 due to heat generation.
[0033]
Next, a second example of the present invention will be described with reference to FIG.
[0034]
In this example, the reinforcing ribs 7 and 8 in the first example described with reference to FIGS. 1 to 3 are omitted. Further, the annular protrusion 10 protrudes upward from the bottom, and a step portion is formed as a support portion 9 on the inner peripheral surface of the annular protrusion 10. The heating element filling container 1 has a heat insulating cylinder 1b fitted on the outer periphery of the container main body 1a, and is inserted into the inside of the annular protrusion 10 to a position where the bottom part abuts on the support part 9 which is a stepped part. The upper surface of the heat insulating cylinder 1b is locked by the locking portion 4. Accordingly, the heating element filling container 1 is sandwiched and held between the support portion 9 and the locking portion 4 and fitted in the heat insulating cylinder 1b.
[0035]
In the case of the outer container 3 as described above, even if the reinforcing ribs 7 and 8 in the first example described above are omitted, the lateral displacement of the stored heating element filling container 1 can be suppressed by the annular protrusion 10. it can.
[0036]
Further, a third example of the present invention will be described with reference to FIG.
[0037]
Also in this example, the reinforcing ribs 7 and 8 in the first example described with reference to FIGS. 1 to 3 are omitted. Moreover, although the annular protrusion 10 protrudes upward from the bottom, it does not have a step on the inner peripheral surface as the support portion 9 in the second example. The heat generating body-filled container 1 has a heat insulating cylinder 1b fitted on the outer periphery of the container main body 1a. The lower part of the heat insulating cylinder 1b protrudes downward from the main body 1a, and the lower part of the protruding heat insulating cylinder 1b is externally provided. The heating element filling container 1 is supported by fitting on the outer peripheral side of the annular projecting portion 10 to a position where it abuts on the bottom of the container 3. That is, in this example, the bottom part of the outer container 3 functions as the support part 9.
[0038]
In the case of the exterior container 3 as described above, as in the second example, even if the reinforcing ribs 7 and 8 in the first example are omitted, the stored heating element filled container 1 is displaced in the lateral direction. Can be pressed by the annular protrusion 10.
[0039]
9 and 10 show a fourth example of the present invention, and the cutting line 5 in this example has a lower end near the same level as the support part 9 (approximately 15 mm above the support part 9 to about 15 mm below). The reinforcing rib 7 has a shape that is once constricted in the vicinity of the same level as the support portion 9.
[0040]
If it is set as the above exterior containers 3, as FIG. 11 shows, the side wall part of the latching | locking part 4 part can be greatly folded outward. After the folding, the side wall portion is in a state of being vertically divided into two, and the outer container 3 is in a state where it is easy to elastically expand its diameter. Therefore, for example, even if the heating element filling container 1 having the heat insulating cylinder 1b is strongly fitted to the heat insulating cylinder 1b so that the reinforcing rib 8 bites into the heat insulating cylinder 1b, after the side wall portion is folded outwardly, The heating element filling container 1 can be easily removed by expanding the diameter of the heater 3. Moreover, since it can be set as such a strong fitting state, it is effective in preventing the shift | offset | difference and dropping-out of the heat generating body filling container 1 by the impact at the time of dropping.
[0041]
【The invention's effect】
The present invention is as described above, and has the following effects.
[0042]
