Description of the Invention: [Technical Field] The present invention relates to a container which, in detail, refers to a container made by injection foaming and a method for manufacturing such a foamed container, the container having heat insulation Effect. [Prior Art] According to the container, the container for the beverage must have an insulating effect to provide insulation or to keep it cool. The foaming beverage cup commonly found in the market is a beverage cup made of styrofoam (polystyrene, PS), such as a beverage _ Lilong Cup. /Λ 〇The above method of foaming beverage cups is to first mold the mold, then put the solid foaming material into the mold, re-mold the mold, and heat the mold to heat the material in the mold. The foaming conditions are foamed and shaped according to the shape of the cavity. As is known in the art, the existing beverage cups made by the foaming technique are molded by the above-described method, and a beverage cup has not been developed by injection molding foaming. Q In addition, the beverage cups in the business premises, whether they are sold in convenience stores or beverage shops, are mostly plastic injection molded plastic cups. The number of foamed beverage cups or paper cups is less than that of plastic cups. The circumference of the beverage cup is usually marked with graphics and the like. The current graphic of the foaming beverage cups is transfer, which is inconspicuous in color and pattern. The plastic injection moldinger can integrally coat the label film on the circumferential surface of the beverage cup during the injection molding process, resulting in a so-called in-mold labeling method, such as the applicant's application No. 89216100 "Plastic film labeling" "The machine", No. 91211119, "The suction removal unit of the plastic film in-mold labeling machine" and the like are shown in the patent case. However, the existing in-mold labeling technology can only be applied to plastic injection molding containers, and the industry has not developed an in-mold labeling foaming container made by injection foaming. 3 201043434 [Description of the Invention] This paper is missing from the solution in the future, and its main purpose is to provide a method for foaming a barn, which is used as a foaming container. The other purpose of the present invention is to provide a method for producing a foaming dance, to make the container (10) foamed, and to combine the technology of the standard ___ with a foaming container. The bubble container has a mechanism structure.制 The method for preparing the injection foaming container provided by the invention mainly comprises injecting the foaming material into the boring tool to make the reading material _ with Lailang foaming; and making the hair/packing material in the foaming process Foaming effect in a larger volume of the cavity. The method of the invention is that the foaming material is first injected into the larger volume of the crucible than the product to be molded, and the foaming material is turned over but not yet fixed. The surface of the core eight is a small volume of the product to be molded, so that the foamed material fills the cavity and is shaped into a molded article. The method of the (4) method can make the foaming surface correct and thieves fit, so that it is difficult to achieve the effect of foaming and flipping at the same time. According to the bribery system, bribes are made and fine bubbles are made to create a temperature-isolation effect. [Embodiment] In order to enable the reviewing committee to further understand the objects, features and effects of the present invention, the present invention will now be described in detail with reference to the accompanying drawings. Fig. (Fig.) to Fig. (C) are schematic views of the manufacturing process of a preferred embodiment of the present invention. 201043434 The second figure (A) shows the schematic diagram of the cavity of the first figure (C); the second figure (B) shows the schematic diagram of the cavity of the first figure (A). Figure 3 is a longitudinal cross-sectional view of a foamed container made in accordance with a preferred embodiment of the present invention. The fourth and fifth figures are schematic views of the manufacture of another preferred embodiment of the present invention. Figure 6 is a perspective view of a foamed container made in accordance with the method of Figure 5. The seventh drawing is a longitudinal sectional view of the sixth drawing. Referring to the first figure, a first preferred embodiment of the method for producing an injection foamed container provided by the present invention is shown. In the present invention, a foaming container is formed by injection molding. The container is foam molded by injecting a foaming material into a molding die (4 inch). The method of the present embodiment has the following steps: Please refer to the first drawing, which is a first preferred embodiment of the method for producing an injection-foamed container provided by the present invention. The invention is formed into a foaming container by injection molding, and by injecting the foaming material into the forming mold (4〇), the foaming material is first foamed in the cavity with a larger volume, and then the volume is made in the volume. The reduced cavity is shaped inside. The manufacturing process is as follows: 1. The mold is in a micro-opening state, so that the cavity volume of the mold is slightly larger than the volume of the finished product. Please refer to the figure (A) of the mold (40) of the mold (42) ( 421) forming a cavity (45) between the cavity (441) of the female mold (44). The present invention takes a cup as an example, so that the wedge (45) is in the shape of a cup; other types or shapes of containers For example, a bowl or the like can be made by changing the shape of the cavity. The method of this embodiment firstly causes the mold (40) to be in a slightly open state, i.e., the mold core (421) extends into the cavity (441) but the mold has not been completely closed. At this time, the volume of the cavity (45) between the male and female molds (42) (44) is slightly larger than the volume of the product to be manufactured. Taking the second figure as an example, the first figure (A) shows that the mold (4〇) is in a closed state, the gap of the cavity (45) is W1; 5 201043434 and the figure (B) shows that the mold is not completely closed. The mold is in the micro-opening state referred to in this step, and the gap between the mold holes is W2 '嶋W2 (for example, 16~2 2 faces, but not limited thereto) is larger than the gap W1 when the mold is closed (for example, 〇^ 〇 The leg, but not limited to this.) The cavity gap W2 of the micro-opening is about twice as large as the cavity gap of the mold clamping, for example 2.2 times. 2. The foaming material is injected into the cavity, and then the high temperature (for example, 1 〇〇. 〇~25 〇. 〇 foaming material (52) (plasticized material mixed hair _) is quantitatively shot by the injection tube (50). The person lie (45), as shown in the first figure (9), the weight of the foaming material (52) is the weight required for the object to be molded. Since the mold is in the micro-open state, the 敎(45) has a larger surface than the shot. The volume of the material, so the injection material does not completely fill the cavity. In addition, because the mold (4〇) is not completely closed, the air in the cavity (45) easily flows and escapes from the cavity, so the foaming material is easy. Injection into the cavity, less resistance. The foaming material has reached a foamable chemical reaction in the injection tube (5〇). Preferably, the foam material of the invention is pp (polypropylene), which can be recycled. It does not produce toxicity, and it is different from the conventional foaming container made of ps plastic (polystyrene). 3. After the foaming material is foamed in the cavity but not completely shaped, the mold is made. 〇) Maintaining the micro-opening state for a suitable time to cause the hair/pack material (52) to foam in the cavity (45) but not fully shaped, still having plasticity. Due to the micro-opening state The volume of the cavity is still larger than the volume of the injection material. Therefore, the foamed material is foamed in a large cavity space, and there is sufficient space for the foamed material to foam. During the foaming process, the foamed material is foamed. When expanding, the air in the cavity will escape into the foamed material. And because the mold (4〇) is not completely closed, the foamed material is easily swollen in the void position of the cavity. The foam is shaped according to the shape of the cavity, and when the foamed material is properly foamed and unshaped, the mold (4〇) is closed, as shown in Fig. 201043434 (C) 7 die eight (45) valley product shrinkage, so that the foam The male and female molds (42)(44) 雠' are completely filled in the mold cavity (45). After the mold is closed for a certain period of time, the foam is shaped according to the shape of the mold cavity. The volume is the size of the product to be finished. Therefore, the shape after molding is the size of the product to be finished. This is a case where the clamping faces of the male and female molds (42) and (4) are respectively provided with a ring of tenons (10) and -®. Supplement (48) 'close to the maximum outer diameter of the cavity. The mold (4) during the micro-opening and clamping of the mold, although the volume of the cavity (45) changes, the convex (4) 6) And the ring groove (48) still docks with each other, and the cavity is completely intact, and no flashing occurs.
