DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cold / warm container made of foamed plastic or a hard case, which is used for delivery of cold products or home products of warm products. is there.

[Conventional technology]

As a method of transporting the cold-preserved products, there are a case of using a dedicated refrigerating vehicle and a case of storing them in a foam plastic container together with dry ice, a cold storage agent, and the like, and transporting them in an ordinary carrier.

[Problems to be Solved by the Invention]

When transporting by cold storage car, not only is the equipment costly, but because a dedicated cold storage car is used, it is not possible to mix ordinary luggage, and it is necessary to run regardless of the amount of luggage. There is a lot of waste, and shipping costs are inevitably high. In addition, since the cold storage compartment has a uniform temperature, there is a problem that frozen, chilled, and cool products having different storage temperatures cannot be stored in the same compartment. On the other hand, when using a foamed plastic container, it is possible to mix it with other packages in a normal delivery vehicle for home delivery etc., but since the cool storage time is short at 5 to 10 hours, long distance delivery It is also suitable for delivery that takes hours after the client leaves the client's hand, such as a general courier-like delivery route (through an agency point and some collection centers). It doesn't. On the other hand, foods such as deep-fried foods and boiled foods that have been cooked once have the trouble of having to be reheated when eating because they are cooled during transportation because there is no suitable heat-retaining device. May damage the taste.

The present invention has been made to solve these problems, and it is possible to store cold-cooled products and mix them with general cargo, keep the cold storage time long, and set the temperature for each individual container. In addition, the temperature setting operation can be performed easily and surely, and it is an object of the present invention to provide a cold insulation container that contributes to the distribution of cold-required products.

Another object of the present invention is to provide a heat insulating container that can keep the temperature of food that has been cooked once during delivery.

[Means for Solving the Problems]

The present invention comprises a container and a lid, and the lid is always forcibly held in a closed state via an elastic member such as rubber or a spring, and the lid and the upper portion of one side surface of the container. A flat cooler or warmer insertion opening is formed between the cooler and warmer to allow the cooler or warmer to enter the body through the insertion opening against the elastic member, and to cool or cool the body. The above-mentioned problems have been solved by a cold / heat-retaining container characterized by having a temperature zone setting unit corresponding to the heating unit.

[Work]

During transportation or storage at a collection center or the like, the inside of the container is continuously cooled or heated by a cooler or a warmer inserted through the insertion port. The cooling or heating temperature at that time is selected by the action of the temperature zone setting unit. The lid is always kept in a closed state by the elastic member and does not open unnecessarily even when the cooler or the like is inserted. The container is
It can be mixed with general luggage in a delivery vehicle equipped with a cooling (heating) unit.

A preferred embodiment of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 is a container made of foamed plastic, and a step 2 is provided above the inner side surface of the container, on which the edge of the lid 3 is placed. The one end 4 of the lid 3 is cut at both corners to have the same width as the laterally long insertion opening 5 formed at the upper end of one side surface of the container 1 so that it can be fitted therein. Therefore, the insertion opening 5 is closed by the one end 4 of the lid 3. A cooler or a warmer, which will be described later, pushes up the side end 4 of the lid 3 and enters the insertion opening 5.
In order to facilitate the entry, a slope 4a is formed below the one end 4 so as to open outward. 6 is a rubber band groove, which is formed at four corners or side surfaces of the container 1, or from the container 1 to the lid 3. In the rubber band groove 6, the container 1
A groove-shaped rubber band 7 that is hung from the to the lid 3 is fitted. By constantly pulling the lid 3 downward by the rubber band 7, the insertion port 5 is held in the closed state. FIG. 3 shows a mounting example in addition to the rubber band 7, and the rubber band 7 is hooked so as to straddle the lid 3 between the protrusions 8 projecting on both side surfaces of the container 1 or in the rubber band groove 6. It is a thing. Further, as shown in FIG. 4, a rubber band 7 is hung between the protrusion 8 provided on the side surface of the container 1 and the protrusion 9 provided on the side surface of the lid 3. A plurality of rubber bands 7 may be hung in parallel, or may be hung in the longitudinal direction of the container 1. In the embodiment shown in FIG. 5, instead of the above rubber band, both ends are made of metal, plastic or the like.
A rubber band 11 provided with 10 is used, and the rubber band 11 is straddled over the lid 3 so that the claw 10 can bite the side surface of the container 1. In FIG. 6, reference numeral 12 is a safety seal, which is attached from above the rubber band 7, the rubber band 11 or the like at the time of delivery (usually attached to both side surfaces of the container 1) to prevent the lid 3 from being opened unduly. It is for. Due to this, the intentional mixture of poisonous substances, the introduction of dust and the like are prevented, and the safety and reliability of the product and the feeling of cleanliness are secured.
Reference numeral 13 is a tape attached to the lid 3 in order to prevent the end portion of the lid 3 from floating and shifting. Cover 12a in FIG. 9
Is used for the same purpose as the safety seal 12 above,
It is made of paper or a plastic sheet, and covers the upper part of the container 1, and the edges thereof are fixed to the side surface of the container 1 with a tape or the like. Advertisement characters and the like can be appropriately displayed on the cover 12a. Further, the one shown in FIG. 7 is mainly adopted for the container of the hard case, one end is fixed to the side surface of the container 1 and the other end of the tension spring 14 is fixed to the lid 3, so that the rubber band 7 It is intended to perform the same action as the rubber band 11. Further, the one shown in FIG.
The lid 3 is held down by a, and the stopper 14a is rotated downward when inserting the cooling plate or the heating plate (state of imaginary line). In this embodiment, the ridge 3a provided on the side end of the lid 3 is pivotally supported by the lateral habit of the container 1,
The side edges do not float. This structure can of course be adopted in other embodiments, in which case the tape 13 may be omitted.

Returning to FIG. 1, reference numeral 15 is a locking groove formed at the lower corners of both corners of the container 1, and stoppers 17 extending from the cooling unit 16 are engaged with the locking grooves to prevent the container from moving due to shaking of the transport vehicle. To be prevented. The type of the stopper 17 is arbitrary, and accordingly, the position and shape of the locking groove 15 also change accordingly. FIG. 10 and FIG. 11 show such an example. In addition, the bottom of the container is shown in FIG.
It is shown on its side in FIG. Returning to FIG. 1 again, 18 is a temperature zone setting unit, for example, three removable protrusions.
It is composed of 19 to 21, and each of the salients 19 to 21 is associated with a temperature range such as freeze, chilled, and cool. As the temperature zone setting unit 18, instead of being removable like the protrusions 19 to 21, a filling material is embedded in the hole provided in the portion, and the selecting unit is projected or closed in reverse. Good. Alternatively, instead of the embedding material, a cover seal may be attached only to the selection part. Further, a means of providing a vertically movable pusher element and moving only the selected pusher element upward or downward can be considered. In short, it suffices if the selected part is in a state different from other parts. It is preferable to provide about three selection units of the temperature zone selection unit 18 as shown in the drawing, but at least one selection unit is sufficient. On the other hand, for the cooling unit 16, these protrusions 19-
Remote switches 22 to 24 (not necessarily three) are installed at positions corresponding to 21 (Fig. 12), and one of the remote switches 22 corresponding to the selected and removed protrusions 19 to 21. ~ 24 enters, and the inside of the container is cooled in that temperature zone. For a number of steps, such as long-distance transport or regular courier, i.e., a delivery route that goes through an agent and some collection centers, it can take hours to be delivered by the client. , Meanwhile, at the terminal agency,
At each step of the center, base, etc., it is troublesome that a different person handles the container and adjusts the cooling temperature for each container, and at that time, the cooling temperature setting may be erroneous. If the remote switch 22 to 24 switching operation method by 18 is adopted, the above problems can be solved at once.

The cooling unit 16 shown in FIG. 12 includes a compressor, a condenser,
A general refrigeration system including a heat exchanger and the like is built in, and a large number of horizontally extending racks 25 are provided, on which containers are placed and held. In addition, a cooling plate 26 for each rack 25
And the remote switches 22 to 24 are provided so that individual cooling can be performed in a desired temperature zone for each container. With respect to this cooling unit 16, after setting the temperature zone by an operation such as removing any one of the protrusions 19 to 21 in the temperature zone setting section 18, when the container is placed on the rack 25 and pushed in, the cooling plate 26 becomes From the slope 4a at the end of the lid 3, the lid 3 enters the insertion opening 5, pushes up the lid 3 against the tensile force of the rubber band 7, the rubber band 11 or the tension spring 14, and further enters the container. When the container is pushed all the way in, the tip of the stopper 17 engages with the locking groove 15 of the container 1 to firmly hold the container. Further, when the temperature zone setting unit 18 acts on the remote switches 22 to 24 at that position and the remote switch corresponding to the set temperature zone is turned ON, cooling by the cooling plate 26 is performed in that temperature zone.
