When the product passes, the inner door side flap 21 closes the product outlet 20 by its own weight, and outside air heat enters the storage from the product outlet 20, or conversely, the heat in the storage (cold or unheated) Prevents hot air from escaping to the outside. And since the heat insulation layer 21e is provided in the inside of the inner door side flap 21, the calorie | heat amount which enters / exits between the inside of a storage and the exterior of a storage via the inner door side flap 21 is reduced efficiently.
Then, the product purchaser opens the product take-out port 11 by rotating the lower end side of the outer door side flap 14 forward, and takes out the product dispensed into the product receiving member 13. And the outer door side flap 14 obstruct | occludes the goods extraction port 11 with the dead weight.

  Next, about the manufacturing method of the inner door side flap 21 for the vending machine of this embodiment, in the case of using a so-called WIM (Welding In Mold) molding method, with reference to FIG. 3 and FIGS. Briefly described.

  First, as shown in FIG. 5, the 1st molded object 21c, the 2nd molded object 21d, and the heat insulating material 21e are each formed by injection molding. Next, as shown in FIGS. 6 and 7, a heat insulating material 21e is incorporated in the second molded body 21d. And as shown in FIGS. 8-10, by fitting the collar part 21c1 of the 1st molded object 21c in the fitting part 21d2 of the 2nd molded object 21d, the 1st molded object 21c and the 2nd molded object 21d A combination member is manufactured. Next, although not shown in the drawing, is this assembled member fitted into a mold for joining the first molded body 21c and the second molded body 21d, and is the heat insulating material 21e incorporated into the inside through the third through hole 21d5? Check if it is final. When not incorporated, the heat insulating material 21e is incorporated. When incorporated, after the mold is closed, the flow path is provided through a resin injection gate formed at an appropriate location on the mold side at a position corresponding to the flow path 21f. Resin is injected into 21f. When the resin is injected into the flow path 21f, the peripheral portion of the portion in contact with the resin is melted by the heat of the resin and becomes integrated with the resin in the flow path 21f. Thereby, the first molded body 21c and the second molded body 21d are melt-bonded via the resin filled in the flow path 21f. Thus, the 1st molded object 21c and the 2nd molded object 21d are joined by melting a mutual peripheral part (in this embodiment, the part which divides and forms the flow path 21f). Further, when the resin is filled into the flow path 21f, as shown in FIGS. 11 to 13, the communication holes (21c5, 21d4) communicating with the flow path 21f are also filled with the resin to form rivets 21g. Is done. Then, the mold is opened, the molded product in which the first molded body 21c and the second molded body 21d are joined is taken out, and the third through hole 21d5 (see FIG. 3) of this molded product is filled with a resin or the like, The inner door side flap 21 is completed.

  According to the inner door side flap 21 for the vending machine and the vending machine 1 having the same according to this embodiment, the inner door side flap 21 having the heat insulating material 21e therein is the first molding made of thermoplastic resin. A first molded body 21c and a second molded body 21d made of a thermoplastic resin molded separately from the first molded body 21c. The first molded body 21c and the second molded body 21d are melted at their peripheral portions. Therefore, the first molded body 21c and the second molded body 21d are individually and easily formed with high accuracy by the flap thickness (t1, t2) required by injection molding. In addition, after the heat insulating material is positioned between the first molded body and the second molded body, the peripheral edge portions of the first molded body and the second molded body are surely joined by melting to form a flap having the heat insulating material 21e inside. Can do.

  Thereby, it is an inner door side flap having a heat insulating material inside, and an inner door side flap for a vending machine which can be easily formed with a flap thickness according to weight reduction, and this inner door side flap. A vending machine equipped can be provided.

  In the present embodiment, the first molded body 21c and the second molded body 21d are configured to be combined with each other so as to form a resin-filled flow path 21f between the peripheral edges of the first molded body 21c and the second molded body 21d. It was set as the structure melt-joined through resin with which it fills. In this way, by joining the first molded body 21c and the second molded body 21d by using a so-called WIM molding method, the bonding strength is obtained by simply joining them by, for example, the vibration welding method. The strength can be increased to 1.5 to 2.0 times the strength.

  In the present embodiment, the flow path 21f is formed so as to be exposed to the flap outer surface on one side in the flap thickness direction. Thereby, the flow path 21f for WIM molding is provided on the inner door side flap 21 formed with a flap thickness t of about several millimeters so that it can be mounted in a narrow space between the vending machine main body 2 and the outer door 3. It can be formed easily. The flap outer surface on one side in the flap thickness direction where the channel 21f is exposed is the surface on the vending machine main body 2 side of the first molded body 21c. Thereby, since the trace of the flow path 21f is not visible from the front side (front side) of the inner door side flap 21 in the completed state, it is preferable from the aesthetic point of view.

And in this embodiment, the communication hole (21c5, 21d4) which connects the bottom face of the flow path 21f and the flap outer surface of the flap thickness direction other side is formed, and this communication hole is further filled with resin. It was. Thereby, since the contact area of resin and the peripheral part of the 1st molded object 21c and the 2nd molded object 21d increases, adhesive strength can be raised more. In the present embodiment, the communication hole has been described as including the first through hole 21c5 and the second through hole 21d4. However, the present invention is not limited thereto, and the communication hole may be configured only from the second through hole 21d4. In this case, the flange 21c1 on the upper end side of the first molded body 21c is formed to be short like the flange 21c1 on the lower end side shown in FIG. 9, so that a flow path 21f in contact with the support portion 21d1 is formed. What is necessary is just to comprise so that the bottom face of this flow path 21f may communicate directly with the 2nd through-hole 21d4.
Moreover, in this embodiment, although the communication hole demonstrated in the case where it forms in the peripheral part of an upper end side, you may form not only in this but in the peripheral part of a lower end side and flap width direction both ends. In this case, the communication hole may be formed so as to penetrate both the first molded body 21c (the flange portion 21c1) and the second molded body 21d, or the communication hole may be formed so as to penetrate only the second molded body 21d. It may be formed. In the case of forming a communication hole penetrating only the second molded body 21d at the peripheral edge portions at both ends in the flap width direction, for example, the length of the flange portion 21c1 shown in FIG. A flow path 21f in contact is formed.

  Further, in the present embodiment, the communication hole is formed to have an enlarged diameter at the end portion on the flap outer surface side on the other side, and has a configuration having a rivet portion 21g in which the communication hole is filled with resin. Thereby, the joint strength of the 1st molded object 21c and the 2nd molded object 21d can further be raised.

  In the present embodiment, the case where the heat insulating material 21e is included is described. However, the present invention is not limited to this, and a space is simply provided between the first molded body 21c and the second molded body 21d, and the space is insulated. It is good also as the space 21e.

  In the present embodiment, a flow path 21f is formed between the peripheral edge of the first molded body 21c and the peripheral edge of the second molded body 21d, and the first molded body 21c and the first molded body 21c are formed using the WIM molding method. Although it demonstrated by the case where the 2 molded object 21d was joined, it is not restricted to this, For example, you may join by heat caulking or vibration welding (including ultrasonic welding), and the 1st molded object 21 and the 2nd molded object However, what is necessary is just to join by melting each peripheral part. In this case, it is not necessary to provide the flow path 21f. For example, in the case of heat caulking, an electric heat source such as an electric heater or an optical heat source using infrared rays is used to heat the peripheral portion of the first molded body 21c and the peripheral portion of the second molded body 21d together with the caulking. In addition, it is melted and the peripheral portions of these are melt-bonded directly. In the case of vibration welding, vibration is applied to the peripheral portion of the first molded body 21c and the peripheral portion of the second molded body 21d, and the peripheral portions are directly melt-bonded by the vibration. Even with these joining methods, the first molded body 21c and the second molded body 21d can be formed separately by injection molding, and therefore can be easily formed with a flap thickness corresponding to weight reduction. An inner door side flap 21 for a vending machine can be provided.

  In the present embodiment, the “vending machine flap” according to the present invention is applied to the inner door side flap 21 that closes the commodity outlet 20 opened in the inner door 4 of the vending machine 1. However, the present invention is not limited to this. For example, the product may be applied to the outer door side flap 14 that closes the product outlet 11 opened in the outer door 3, and the product stored in the vending machine main body 2 may be used. Any flap provided in the product carry-out unit 30 to be carried out may be used.
