Description
【発明の詳細な説明】 本発明は、断熱箱体の製造方法に関する。[Detailed description of the invention] The present invention relates to a method of manufacturing a heat insulating box.
一般に冷却又は加温商品を−ｆｆｌ５自動販売機に於い
ては外箱の塗装の剥げや打痕等により外箱のみ交換する
ことが多々あるために、発泡ウレタン等の一体発泡方式
では外箱と内箱とを離すことができないので望ましくな
い。In general, when using refrigerated or heated products in -ffl5 vending machines, only the outer box is often replaced due to peeling of the paint or dents on the outer box. This is not desirable because it cannot be separated from the inner box.
ところが発泡スチロール断熱材より発泡ウレタン断熱材
の方が断熱効果があり、このため断熱材の厚さも薄くて
済むために、内部の商品収納室を拡大させるには発泡ウ
レタン断熱材の方が望ましいという事態に直面する。However, urethane foam insulation has a better insulation effect than styrofoam insulation, and because of this, the thickness of the insulation material can be thinner, so urethane foam insulation is preferable to expand the internal product storage space. face.
斯る点に鑑み、本発明は成されたもので以下一実施例を
図に基づき詳述する。In view of the above, the present invention has been made, and one embodiment will be described in detail below with reference to the drawings.
断熱箱体であるところの前面を開口する冷却商品自動販
売機本体１は、夫々金属性である内箱２と外箱３、及び
両箱間に充填する断熱材４で構成されている。The main body 1 of the refrigerated product vending machine, which is an insulated box with an open front, is composed of an inner box 2 and an outer box 3, each made of metal, and a heat insulating material 4 filled between the two boxes.

form.
而して前記押え具を外して前記両治具１１，１２を外す
。Then, remove the presser and remove both jigs 11 and 12.
斯る後前記両突起部９，１０により前記発泡断熱材１４
が形成されなかった箇所１５を切抜いてその端部を熱に
て溶着する。After that, the foamed heat insulating material 14 is removed by both the protrusions 9 and 10.
The portions 15 where no is formed are cut out and the ends are welded by heat.
また発泡原液を注入した前記袋体１３の開口部１６も熱
にて溶着して第４図及び第５図に示す如《前記袋体１３
にて気密に成された発泡断熱材１４を形成するものであ
る。In addition, the opening 16 of the bag 13 into which the foaming stock solution was injected is also welded by heat, as shown in FIGS. 4 and 5.
The foamed heat insulating material 14 is formed in an airtight manner.
そして該発泡断熱材１４の開口部１７を前記本体１より
滴下する露等を露受皿１８へ導くための開口として用い
る場合について以下述べる。A case where the opening 17 of the foamed heat insulating material 14 is used as an opening for guiding dew, etc. dripping from the main body 1 to the dew receiving tray 18 will be described below.
先ず外箱３の内側の土壁、背壁、両側壁に発泡スチロー

形成せしめた後、該断熱材を外箱と内箱との間に挿入せ
しめるようにしたものである。Then, the present invention incorporates an inner box 2 having an opening 22 at the bottom to collect dew in one place and combines it with the outer box 3. An injection box is formed using an inner box jig and an outer box jig, each of which has been formed, a synthetic resin bag is inserted into the box, and a foaming solution is injected into the bag to form a foam insulation material. Then, remove both the jigs, cut out the parts where the heat insulating material was not formed by the protrusions, and weld the ends, and also weld the opening of the bag to make the bag airtight. After the heat insulating material is formed, the heat insulating material is inserted between the outer box and the inner box.

費す労力及び材料等は軽減できる。Therefore, when applied to an insulating box that has openings for inserting various instruments and devices or for draining dew water accumulated inside the refrigerator to the outside, the one-piece foaming method is troublesome, i.e., foaming liquid is required. It is possible to reduce the labor and materials required to use a closing member to prevent water from leaking or from entering the heat insulating material, or to tightly connect the inner box and the outer box.
更には袋体にて気密にされた断熱材であるために露水の
影響もなく、経年変化に耐え５るものであり、また取扱
いも容易である。Furthermore, since it is an insulating material made airtight by the bag, it is not affected by dew water, can withstand changes over time, and is easy to handle.
また断熱材を作成する際は、治具の表面に断熱材が付着
することはないものである。Furthermore, when creating the heat insulating material, the heat insulating material does not adhere to the surface of the jig.
而して外箱の塗装の剥げや打痕等により外箱のみ交換す
ることが多々生じる自動販売機には誠に好適である。Therefore, it is very suitable for vending machines where only the outer case is frequently replaced due to peeling of the paint or dents on the outer case.
