Description

  The present invention relates to a cold container used for packing and transporting fresh foods such as fruits and seafood in an ice-cold state.

  2. Description of the Related Art Conventionally, cold storage containers, which are molded products of foamed resin, have been widely used for packing and transporting fresh foods such as fruits and vegetables and seafood in an ice-cold state. In this cold storage container, ice for cold storage is stored together with fresh food, but the ice gradually melts during cold storage and transport for a long time and accumulates as molten water at the bottom of the cold storage container. When the fresh food is immersed, the deterioration of freshness and spoilage due to various bacteria will progress.

In the case where the fresh food is broccoli, for example, ethylene gas is generated from the portion immersed in the melted water, resulting in an aging state. Therefore, for example, Patent Document 1 proposes a method for discharging molten water collected in a cold storage container in a timely manner.
This cold storage container has a through-hole that penetrates inside and outside in order to discharge the accumulated molten water to the outside, and a through-hole that prevents outside air from entering through the through-hole during transportation to increase the internal temperature. And a water stop cock for sealing the inside.

  In this cold storage container, the water stop cock is pulled out from the through hole at the transfer relay point, etc., and the melted ice accumulated inside is discharged to the outside. Decrease in freshness of broccoli and spoilage due to various bacteria can be avoided while maintaining a warm and cold state.

Japanese Patent No. 4071079

The above-described conventional cold container has the following problems to be solved.
That is, the water stop cock that is inserted into and removed from the through-hole penetrating into and out of the cold storage container is prepared independently of the container body of the cold storage container, and is used to be inserted into and removed from the cold storage container. In many cases, it was lost due to misplacement during the work before and after being stored in the cold container.

  The present invention has been made in view of the above-described circumstances, and its purpose is to use, as a water stop cock, the melted water that has accumulated in the bottom of the cold storage container due to melting of the cold storage ice when the transport time is long. By sliding the water stop / drain plug in the axial direction, the water can be drained quickly, and after discharging, it can be stopped quickly by sliding in the reverse direction in the axial direction and sliding it back to the original position. It is an object of the present invention to provide a cold storage container that can make water and can prevent the loss of the water stop / drain plug as a water stop cock due to misplacement before and after the water stop operation and discharge operation of melted water.

In order to achieve the above-mentioned object, the cold storage container with a water stop / drainage stopper according to the present invention is a container main body made of foamed synthetic resin for storing fresh food together with ice for cold storage, and is detachable from the container main body. A lid that is mounted and seals the container body,
The container body is provided with a drainage hole that penetrates the inside and outside of the lower portion of the side wall and drains the melted water of ice accumulated in the container body. -A drainage stopper is slidably mounted, and the water stop / drainage stopper is inserted into the drainage hole with a long hole or slot or a slot and slot with a length exceeding the thickness of the side wall of the container body. A continuous combination is provided in the axial direction, and the drainage hole can be opened and closed by sliding back and forth in the axial direction for a predetermined stroke along the drainage hole.

  With this structure, the water stop / drain plug is inserted into the drain hole of the container body and attached, so that the inside of the container body covered with the lid is kept in a sealed state, and the inside of the container body is used for cooling. Fresh food stored with ice can be placed under a predetermined ice-cooling temperature. On the other hand, the ice for cold insulation gradually melts due to transportation for a long time, etc.In this case, in order to determine the timing when the melted water amount reaches a predetermined amount, The drainage plug is slid in the drainage hole, for example, by a predetermined stroke length in the pulling direction.

  By sliding the water stop / drain plug, at least both ends of the long hole or the long groove or the combination of the long hole and the long groove formed in the water stop / drain plug are simultaneously in and out of the side wall of the container body. You will communicate. For this reason, the melted water that has been melted and accumulated at the bottom of the container body naturally flows out of the container body through the long holes or the long grooves or the combination of the long holes and the long grooves. As a result, it is possible to prevent the fresh food from being deteriorated by bringing the fresh food directly into contact with the molten water in the container body.

  On the other hand, immediately after the molten water is discharged from the inside of the container body, immediately push the water stop / drain plug into the drain hole so that the long hole, the long groove, or the combination of the long hole and the long groove is outside the side wall. Slide it to a position where it does not face. Accordingly, the drain hole can be sealed to stop the water, and the intrusion of the outside air into the container body is prevented, so that the temperature rise in the container body due to the outside air can be avoided. Accordingly, the inside of the cold container is again kept in the ice temperature cold state, and the freshness of the fresh food is well maintained for a long time.

  In addition, the water stop / drain plug only slides in the drain hole and is not attached to or detached from the drain hole. The water stop / drain joint plug slides in the drain hole, so that the molten water can be selectively discharged and stopped. As a result, it is possible to reliably avoid the problem that the water stop / drain plug is misplaced and lost before and after the drain operation and the water stop operation.

  In addition, the long groove of the water stop / drain plug used in the cold insulation container with a water stop / drain plug according to the present invention has a cross-sectional arc shape in which water flow is easily induced, and the bottom surface at one end is tapered to the outer peripheral surface of the shaft portion. It is characterized by being continuous.

  With this configuration, the water flow for draining the ice melt is improved, and foreign matter (for example, broccoli flower scraps) can be smoothly discharged together with the drainage.

  Further, in the inner bottom portion where the drainage hole of the container body in the cold insulation container with a waterstop / drainage plug of the present invention is located, a portion extending to the inside of the waterstop / drainage plug attached to the drainage hole, A pair of protrusions are provided in parallel so as to surround from both sides.

  With this configuration, even if the contents move due to shaking during transportation, it is possible to prevent the contents from coming into contact with the water stop / drain plug that extends into the container body. It is possible to prevent the water from leaking due to loose contact with the inner wall of the drain hole due to displacement from the normal position of mounting due to contact with the water stop / drain plug.

  Furthermore, the cold insulation container with a water / drain joint plug according to the present invention is provided with an annular knob on one end side of the shaft portion of the water / drain plug, and the annular knob has a long groove or a long hole. It is characterized by having a cut part on the extended line.

  With this configuration, when the water stop / drain plug is attached to the cold storage container, it can be confirmed on which side of the shaft the slot or slot is located, and the cut part can be removed even if it is removed and placed. Can prevent rolling.

  According to the present invention, when the transport time is long, etc., the melted water that has been melted and accumulated at the bottom of the cold storage container can be quickly discharged by sliding the water stop / drain plug. In addition, the drainage can be stopped by quickly sliding the water stop / drainage plug back to the original position after the discharge, and the water stop / drainage plug is used before and after the water stoppage and discharge work. Can be lost.

  The present invention has been briefly described above. Furthermore, the best mode for carrying out the invention described below will be described in detail with reference to the accompanying drawings.

It is a perspective view which shows the other water stop / drainage plug in the present invention.

  Hereinafter, the cold insulation container concerning embodiment of this invention is demonstrated in detail with reference to FIG. 1 thru | or FIG.

  FIG. 1 is an exploded perspective view showing the entirety of a cold insulation container with a water stop / drainage combination stopper according to the present embodiment. The cold-insulated container with water stop / drain plug (hereinafter also referred to simply as a cold container) A includes a container body 11 and a lid 12. The container main body 11 and the lid body 12 are formed of a synthetic resin foam such as polystyrene, and both have a rectangular shape in plan view and are formed in a thick size having a predetermined strength.

  The opposing side wall 13 of the container body 11 is formed with a substantially rectangular concave portion 14 that can be put on by a person when the cold container A is transported. A round drainage hole 15 penetrating in the horizontal direction is formed. A water stop / drain plug 16 made of, for example, rubber, metal, synthetic resin or the like is inserted into the drain hole 15 and, after being inserted, is supported in the drain hole 15 so as to be slidable in the axial direction. . The water stop / drain plug 15 is slidable in the axial direction with respect to the drain hole 15 after being inserted into the drain hole 15, but cannot be pulled out from the drain hole 15 (for example, the tip of the shaft portion). It is desirable to have a structure in which a protrusion or a flange for preventing the protrusion is provided.

  On the other hand, as shown in FIGS. 2 and 3, the container body 11 has a protruding portion 17 that gently protrudes in a circular arc shape over a predetermined width at the center of the bottom surface. Water collecting grooves 18 are formed on both sides of the protrusion 17. The projecting portion 17 is tapered in the vicinity of the drainage hole 15, and the water collecting grooves 18 on both sides merge at this portion to form a water collecting portion 19 that continues to the drainage hole 15. When the water collecting portion 19 is positioned lower than the bottom surface in the container main body 11 and is connected to the drain hole 15, the melted ice in the container main body 11 is reliably transferred from the water collecting groove 18 to the water collecting portion 19. It is preferable because the water is completely drained from the flow-in drain hole 15.

  A pair of protrusions 20 are erected on the water collecting portion 19 with an interval substantially matching the diameter of the drain hole 15. These protrusions 20 enable the water stop / drain plug 16 to be mounted and reciprocally slid straight and smoothly with respect to the drain hole 15. Further, the pair of protrusions 20 prevent the contents from coming into contact with the portion that is inserted into the drain hole 15 and extends (enters) into the container body 11, and thus the contents move due to shaking during conveyance. Thus, it is possible to prevent the water leak from occurring due to loose contact with the inner wall of the drainage hole 15 due to contact with the water stop / drainage stopper extending into the container body 11 and shifting from the normal position of the mounting. Thereby, the close state of the water stop / drain plug 16 and the drain hole 15 is improved, and as a result, water leakage can be surely prevented.

  A fitting step portion 21 that engages with a fitting step portion 12 a (see FIG. 7) of the lid body 12 when the lid body 12 is mounted is formed on the upper end edge of the container body 11. Although not shown, the shape and number of the protrusions 17 and the water collecting grooves 18 can be arbitrarily selected and performed.

The water stop / drain plug 16 is configured, for example, as shown in FIG. The water stop / drain plug 16 has a shaft section 22 having a circular cross section, a knob section 23 from the tip, a flange section 24 for sliding regulation, an arc-shaped reduced diameter section 25, a large diameter section 26, and a long hole 27. .
FIG.4 (b) is a perspective view which shows the water stop and drainage combined use plug which shows other embodiment. The water stop / drain plug 16A of this embodiment is a case where a long groove 31 is used instead of the long hole 27 of the water stop / drain plug 16 shown in FIG. 4 (a), and the others are shown in FIG. 4 (a). Therefore, the same components are described with the same reference numerals.
FIG.4 (c) is a perspective view which shows the water stop and drainage combined use plug which shows other embodiment. The water / drain plug 16B of this embodiment has a combination of a long hole 27 and a long groove 31 instead of the long hole 27 of the water / drain plug 16 shown in FIG. Since the others are the same as those of the embodiment shown in FIG. 4A, the same components are described with the same reference numerals.

The outer diameter of the shaft portion 22 is formed to be slidable in close contact with the drain hole 15, for example, about 1 to 2 mm thicker than the inner diameter of the drain hole 15. The knob portion 23 and the flange portion 24 are formed to have a larger outer shape than the shaft portion 22. The overall diameter of the reduced diameter portion 25 is smaller than that of the shaft portion 22, and the outer shape of the shaft portion 22 extends from the reduced diameter portion 25 to the flange portion 24, for example, to be a slightly thicker diameter portion 26 that changes in a wave shape. Thereby, the closeness of the drain hole on the foamed resin side with respect to the large-diameter portion 26 is increased by its own restoring action, and the water leakage prevention effect is enhanced as the close contact area is increased.
4 (b) and 4 (c), the knob portion 23 and the flange portion 24 of the water / drain plugs 16A and 16B are annular, and cut portions 23a and 24a are formed on the outer periphery of the elongated hole 27 or the extended line of the long groove 31. Is provided. With this configuration, when the water stop / drain plugs 16A and 16B are mounted on the cold insulation container A, it is possible to confirm on which side of the shaft portion 22 the long hole 27 and the long groove 31 are located, The rolling can be prevented by the cut part even when placing it.

  The long hole 27, the long groove 31, and the combination in which the long hole 27 and the long groove 31 are continuous have an axial length sufficiently larger than the thickness of the side wall 13 of the container body 11 and are formed on the peripheral surface of the shaft portion 22. . The long hole 27 is provided in the shaft portion 22 so as to penetrate from one side surface to the other side surface, and the long groove 31 is provided at two locations on the opposite one side surface and the other side surface. The configuration of the combination of the long hole 27 and the long groove 31 shown in FIG. 4C is such that the axial length of the long hole 27 and the long groove 31 is sufficiently larger than the thickness of the side wall 13 of the container body 11. It has become. In addition, in the long hole 27 shown to Fig.4 (a), the reinforcing rib 28 which prevents this long hole 27 being crushed is integrally provided.

  The water stop / drain plugs 16, 16 </ b> A, 16 </ b> B are formed of rubber, metal, synthetic resin, etc., but if formed of a synthetic resin that can be disposed of in the same manner as the cold storage container A, it is removed from the cold storage container A. This is preferable because it can be disposed of together with the cold insulation container A without waste. For example, when the cold container A is formed of a synthetic resin (for example, polystyrene resin) foam, the water stop / drain plugs 16, 16A, 16B are the same non-foamed synthetic resin (for example, polystyrene resin). It seems to be formed by.

  The water stop / drain plug 16 having such a configuration is set and used so as to be inserted into the drain hole 15 formed in the side wall 13 from the tip thereof. Since the water stop / drain plug 16, 16 </ b> A, and 16 </ b> B all have the same function, the water stop / drain plug 16 will be described below as a representative. When the water stop / drain plug 16 is attached to the drain hole 15 as shown in FIG. 5A, for example, broccoli 29 as a fresh food in the container main body 11 together with the ice for cooling 30 as shown in FIG. As shown in FIG. 7, it is housed, covered with a lid 12, and these opening and closing portions are sealed with tape to enable conveyance.

  When the transport time of the cold insulation container A containing the broccoli 29 is long, the ice for cold insulation melts, and the molten water travels from the projection 17 in the container body 11 to the water collection groove 18 to collect the water collection section. To 19. In this state, as shown in FIG. 5A, the long hole 27 of the water stop / drain plug 16 is in the container body 11 over the entire length, and the large diameter portion 26 is in close contact with the discharge hole 15 to melt the water. The water remains on the water collecting portion 19 and the bottom surface.

  On the other hand, at the timing when the molten water stays in the water collecting groove 18 or the water collecting portion 19 and the water level seems to have reached a predetermined level, the water stop / drain plug 16 is viewed from the state of FIG. As shown in FIG. 5B, it is moved by a predetermined amount in the direction of arrow P. The amount of movement is set so that at least both ends of the long hole 27 of the water stop / drain plug 16 are simultaneously exposed (communicated) to the inside and outside of the side wall 13 of the container body 11. As a result, the molten water staying in the water collecting portion 19 is discharged from one end portion of the long hole 27 toward the outside of the container body (in the direction of arrow Q) through the other end portion.

  Then, at the timing when the discharge of the molten water is completed, the water stop / drain plug 16 is again moved into the drain hole 15 to return to the state shown in FIG. As a result, the entire long hole 27 of the water stop / drain plug 16 is located in the container main body 11, and water is stopped and the intrusion of outside air into the container main body 11 is stopped. Thereby, the inside of this container main body 11 can be kept at a predetermined ice temperature cold preservation temperature again. In this case, for example, ten broccoli 29 are arranged on the protruding portion 17 so that the end portion (stem cut end) of the broccoli 29 in the container body 11 does not fall into the water collecting groove 18. It is desirable to store in two steps.

  As described above, the water stop / drain plug 16 is used for discharging molten water in the container body 11, and therefore the water stop / drain plug 16 needs to be removed from the drain hole 15 of the container body 11. There is no. Therefore, the water stop / drain plug 16 is not misplaced somewhere as in the prior art and is not lost even before and after handling. In addition, if necessary, a stopper for retaining such as a protrusion or a flange is provided on the inner end of the shaft portion 22 of the water stop / drain plug 16 so that the water stop / drain plug can be operated by sliding in the pulling direction. It is possible to reliably prevent 16 from coming out of the drain hole 15.

  FIG. 8 shows another stop / drain plug 16A similar to that shown in FIG. 4 (b). The water stop / drain plug 16A has four long grooves 31 that are sufficiently longer than the thickness of the side wall 13 of the container body 11 in the shaft portion 22. For this reason, the four long grooves 31 are separated by a reinforcing piece 32 having a cross-shaped cross section, and are opened to the outside of the shaft portion 22. The water stop / drain plug 16A is also mounted in the drain hole 15 provided in the side wall 13 of the container body 11 in the same manner as described above, and when the long grooves 31 move across the inner and outer sides of the side wall 13, the container body 11 The molten water inside can be discharged outside through these long grooves 31. The shape and size of the long hole 27 and the long groove 31 are not particularly limited as long as they fulfill the function of discharging molten water.

  As described above, according to the present embodiment, the water stop / drain plugs 16, 16 </ b> A, 16 </ b> B are provided with the long hole 27 or the long groove 31 or the long hole 27 and the long groove 31 having a length exceeding the thickness of the side wall 13 of the container body 11. Are provided, and the water stop / drain plugs 16, 16 </ b> A, 16 </ b> B are moved in the axial direction by a predetermined stroke along the drain hole 15, so that the long hole 27 or the long groove 31 or the long hole 27 and the long groove 31 are moved. Since the molten water in the container main body 11 can be discharged through a continuous combination, at least both ends of the long hole 27 or the long groove 31 or the combination in which the long hole 27 and the long groove 31 are continuous are formed on the side wall 13 of the container main body 11. Exposure (communication) at the same time inside and outside. For this reason, the melted water accumulated by melting ice as described above flows out of the container main body 11 through the long holes 27 or the long grooves 31 in the bottom part (the water collecting groove 18 or the water collecting part 19) in the container main body 11. It becomes possible. As a result, it is possible to prevent the freshness from being deteriorated by bringing the fresh food directly into contact with the melted water in the container body 11.

    The cold storage container of the present invention allows the molten ice accumulated in the cold storage and accumulated at the bottom of the cold storage container to be discharged quickly by sliding the water stop / drain plug, and immediately after discharge. The water stop / drain plug can be stopped by sliding the water stop / drain plug back to the original position, and the water stop / drain plug can be prevented from being lost before and after the water stop / discharge work. It is useful for a cold container used for packing and transporting fresh food such as fruits and vegetables and seafood in an ice-cold state.
