Description of the invention (1) Field of the invention The present invention relates to injection molding in which a preform and a spreader are integrally formed at the bottom of the preform, a preform formed by injection molding, and a container formed by self-preforming by extension blow molding. . BACKGROUND ART The conventional technique discloses a preformed device for placing a liquid ejection container and a bottom spreader integrally by placing a pair of cut-bottom types that face each other and can be moved at the bottom portion of the injection-hole six-type mold. The surface of the component, one of the devices has a spreader hole formed by a vertical straight line, and the other device has a spreader hole bent in a vertical direction. Reference Patent 1: Japanese Patent Publication 0 4-1 6 3 1 0 7 (= US Patent No. 5,0 4 9,7 4 9) Reference Patent 1: Japanese Patent Publication 2 0 0 3-8 0 5 8 8) The invention discloses that one of the conventional techniques for solving the problem of the present invention has the sling hole of the vertical straight line mentioned above, because the sling is formed perpendicular to the bottom surface to extend the blow molding of the pre-shaped entry sling at the bottom. It is difficult to insert the container of the tool into the slot formed by the bottom tool of the blower tool. If the spreader slightly misses the slot opening, the spreader will bend at the bottom and become an obstacle forming the bottom part of the container, and often cause defects. Moreover, the spreader bends from the base of the connection portion and fits into the bottom portion of the container after being formed, but the spreader tends to protrude from the base due to the bent portion (which is made of synthetic resin) and rebound. This affects the self-supporting ability, and the container becomes unstable, so it needs the support of the spreader.
200530006 五、發明說明（2) 置。 在吊具孔穴的情況下，其為彎的及彎曲如犬後足的， 因為吊具亦彎曲如犬後足地形成，當吊具的下端因延伸棒 的延伸而接觸吹氣型具的底部時，該吊具在於底部型具的 彎曲如犬後足的部分被摺疊，此不為成型的障礙，但在此 情況的經摺疊部分亦會彈回，所以，其亦需要吊具的支撐 裝置以防止吊具自底部部份伸出。 整體形成於底部部分的吊具之問題主要為彎曲或摺疊 整體吊具，其係垂直朝向預型底面形成，以將吊具裝配入 容器的底部部分。如此，整體吊具的問題可由形成能夠裝 配入底部部分及當需要使用時能夠將吊具向上彎曲的吊具 解決。 而且，射出孔穴的樹脂路成為吊具孔穴，與射出孔六 相較吊具孔穴容量為相當小的，及與無吊具的普通形式相 較因為突出及彎曲部分流阻變得更高，故在射出及填充合 成樹脂方面不為合人意的。所以，射出成型的問題可由形 成吊具孔穴而解決而不論樹脂的樹脂路。 本發明目的係為提供一種新穎射出成型；其能夠形成 水平及平坦吊具於預型底部且不需彎曲或摺疊吊具以裝配 入容器的底部部分，於此樹脂直接流入該射出孔穴而不需 流經吊具孔穴，故流阻不會增加；且其能夠射出成型預型 即使該吊具較該預型直徑為長。 而且，本發明另一目的係為提供一種底面具吊具之預 型，其係由上述射出成型製造，及容器，其係由延伸吹氣200530006 V. Description of Invention (2). In the case of a sling hole, it is curved and bent like a dog's hind foot, because the sling is also bent like a dog's hind foot. When the lower end of the sling contacts the bottom of the blower due to the extension of the extension rod At this time, the part of the spreader that is bent like the dog's hind feet is folded. This is not an obstacle to molding, but the folded part in this case will also spring back. Therefore, it also needs the support device of the spreader. To prevent the spreader from protruding from the bottom part. The problem of the spreader integrally formed at the bottom portion is mainly a curved or folded integral spreader, which is formed vertically toward the preformed bottom surface to assemble the spreader into the bottom portion of the container. In this way, the problem of the overall spreader can be solved by forming a spreader which can be fitted into the bottom portion and which can be bent upward when needed. Moreover, the resin path of the injection hole becomes a sling hole. Compared with the injection hole six, the sling hole capacity is relatively small, and the flow resistance of the protruding and curved parts becomes higher than the ordinary form without a sling. Unsatisfactory in terms of injection and filling of synthetic resin. Therefore, the problem of injection molding can be solved by forming the hanger hole regardless of the resin resin path. The object of the present invention is to provide a novel injection molding; it can form a horizontal and flat spreader on the bottom of the preform without bending or folding the spreader to fit into the bottom part of the container, where the resin flows directly into the injection hole without the need It flows through the holes of the spreader, so the flow resistance will not increase; and it can shoot the preform even if the spreader is longer than the preform diameter. Moreover, another object of the present invention is to provide a preform of a bottom mask sling, which is manufactured by the above injection molding, and a container, which is extended by blowing air.

The upper contact surface of the bottom type forms a pre-shaped bottom surface, and the resin path is formed between the bottom type contact surfaces. The sprue bushing in the center of the lower part and the flat top surface having contact with the bottom contact surface of the bottom mold are horizontally formed in the hanger hole between the end face of the sprue bush and the bottom contact surface of the bottom mold; tilt into the bottom of the opening and A plurality of guide pins parallel to the outside of the two base patterns parallel to the cone-shaped surface; and a coil spring installed along the guide pins; wherein the guide pins are inserted through the cutting pattern to nail up together, and the shooting pin
第10頁 200530006 五、發明說明（4) 出孔穴型係使用彈性壓縮而裝設及為可移動的以在開口打 開及關閉。 本發明另一方向係關於根據申請專利範圍第1或2項由 射出型所形成的底面具吊具之預型，其具由射出孔穴型所 形成的本體部分，由底型所形成的底部部分，及經由連接 形成於樹脂路的組件而形成於注道襯套的端面及底型下方 接觸表面之間所形成的吊具孔六中的底部表面上的整體水 平吊具；及根據申請專利範圍第3項於其底面具吊具之預 型，其中吊具長度大於該預型直徑，及該吊具包括可自基 底部分向上摺疊的一對對稱環。 本發明另一方向係關於在吹塑成型根據申請專利範圍 第3或4項由延伸吹氣成型底面具吊具之預型所形成的容 器。 本發明作用 在射出成型的情況下，如上所提及，吊具孔穴係在注 道襯套的端面及底型下方關閉表面之間獨立地水平形成， 故樹脂路被密封做為一般的型，及樹脂自該注道襯套直接 射出至該射出孔穴。即使吊具孔穴位於射出孔穴前方，樹 脂的流阻未增加，及沒有任何鎔接處在預型產生。 此外，吊具孔穴係由底型及注道襯套形成，所以，其 減少吊具孔穴的型具部件的數目，與一般型相較，射出型 具的裝配時間並不長，且成本不會變高。 因為當成型模具時吊具藏在容器底部部份，吊具不會 自容器基底突出，容器以具整體形成於底面的吊具而自行Page 10 200530006 V. Description of the invention (4) The hole type is installed using elastic compression and is movable to open and close the opening. Another aspect of the present invention relates to a preform of a bottom mask sling formed by an injection type according to item 1 or 2 of the scope of the patent application, which has a body portion formed by an injection hole type and a bottom portion formed by a bottom type. And the overall horizontal spreader on the bottom surface of the spreader hole six formed between the end face of the sprue bushing and the contact surface below the bottom mold by connecting the components formed on the resin road; and according to the scope of patent application The third item is the preform of the bottom mask sling, wherein the sling is longer than the preform diameter, and the sling includes a pair of symmetrical rings that can be folded upward from the base portion. The other aspect of the present invention relates to a container formed by blow molding a preform of a bottom mask sling according to item 3 or 4 of the scope of the patent application. In the case of injection molding, as mentioned above, the hanger hole is formed horizontally independently between the end surface of the injection bushing and the closed surface under the bottom mold, so the resin path is sealed as a general type. And resin is directly injected from the injection bushing to the injection hole. Even if the spreader hole is located in front of the injection hole, the flow resistance of the resin does not increase, and no joints are generated in the preform. In addition, the spreader hole is formed by the bottom mold and the injection bushing, so it reduces the number of mold parts of the spreader hole. Compared with the general type, the assembly time of the injection mold is not long and the cost is not Becomes high. Because the spreader is hidden in the bottom of the container when the mold is formed, the spreader does not protrude from the base of the container, and the container itself is a spreader with the integrally formed bottom surface.

Description of the invention (7) The preform 10 of the integral sling for the injection molding bottom mask is made by injection molding with the structure described above (as shown in Figure 1). When the injection hole type 1 is In the opened state, the bottom molds 3 and 3 should first move forward to contact each other on their top surfaces to form a resin path 8, a bottom mold surface 12a, and a hanger hole 9. As the next step, when the neck shape 5 and the transfer transfer tray 51 move downward, the injection center 6 first moves into the cutting shape Π, Π, and then the neck shape 5 and the holder 5 2 contact the cutting shape 1 1, The upper surface of 1 1 and the cutting patterns 1 1 and 1 1 are pushed. When the cutting patterns 1 1 and 11 compress the coil spring 2 4 and 2 4 and the guide rods with the guide pins 2 3 and 2 3 are closer to each other. At this time, the cutting patterns 1 1 and 1 1 are pushed into the opening 21. During this pushing movement, the tapered outer surface of the cutting pattern 1 1, 1 1 contacts the inner surface 2 1 a, 2 1 a of the opposite side of the tapered shape of the opening 21, and the cutting pattern 1 1 a, 1 1 a is pushed down to the upper surface of the bottom patterns 3, 3, closed at the bottom of the opening 21 and they are getting closer and closer and completely closed. As a result, the injection hole type 1 (shown in FIG. 3) in the closed state is closed with a neck shape 5, the injection center is placed in the center, and the hole 1 2 of the preform 10 is formed with a hole with a resin path 8 opening. The bottom part of the six 12 is formed between the bottom surface 12 b (formed on the upper contact surfaces of the bottom molds 3 and 3) and the bottom surface of the injection center 6. After the mold is closed, the pressure applied from the neck side is used as the locking force and prevents the injection hole 12 from being opened by the injection pressure. After the mold is closed, when molten resin such as polypropylene is injected into the gate of the runner bush 4 through the injection nozzle 7 described above, the resin flows through the resin path 8 and fills the injection hole 1 surrounding the injection center 6 and within the neck shape 5 2 and the resin also fills the hole 9 of the spreader. As a result, the preform 10 and the horizontal and flat spreader 10a at the bottom

Description of the invention (8) The resin connection and integral formation in the resin path 8 (see Figure 5). In order to remove the preform 10 of the spreader 10a from the mold, first, the ejection space of the spreader 10a is moved from the bottom of the ejection hole 12 to the front of the bottom patterns 3 and 3 by moving the bottom pattern backward to the side Side and release contact are generated. Then, the holding pressure of the cut-resistant types 1 1 and 11 is released by moving the neck shape 5, the injection center 6 and the transfer transfer tray 51 upward. As a result, the cutting patterns 11 and 11 are pushed by the restoring force of the compression coil springs 2 4 and 24 and guided by the guide pins 2 3 and 2 3, and each of the cutting patterns 1 1 and 11 is opened in turn. The inner cone-shaped surface of the hole 21 is moved obliquely upward to the original opening position and away from each other and opening the injection hole 12 to the side. The preform 1 0 surrounding the injection center 6 and the spreader 1 0 a (which is taken out from the injection space between the front faces of the bottom shapes 3 and 3) moves up with the cut shapes 1 1 and 1 1 up to the neck shape 5 is separated from the upper surfaces of the cutting patterns 1 1 and 1 1. As illustrated in Fig. 6, after the cutting patterns 11 and 11 reach the upper limit, the pre-shape 10 moves up to the space above the injection hole pattern 1 with the neck shape 5 and the injection center 6. As illustrated in FIG. 7, after taking out the injection center, it is released from the injection hole type 1 as described above and the preform 10 maintained by the neck shape 5 is in the injection molding or similar to the conventional extension blow molding. After the molding, it is transferred from the transfer transfer tray 51 to the blow molding 5 3 including cutting patterns 5 3 a and 5 3 a, and the space above. The preform 10 is inserted into the blow molding cavity 54 by the downward movement of the transfer transfer tray 51, and is extended by the extension rod 57 toward the bottom mold 56 of the recessed chamber 55 with the spreader 10a and from the self-blow molding center 58.

第15頁 200530006 五、發明說明（9) 吊，如在第8或9圖所說明。成型後自吊具10a中央突出的 注道被切斷及自該頸部移除。 在容器20底部的吊具10a不會自基底突出因為該吊具 1 0 a隱藏在環狀凹所底部部分，所以即使具吊具於底部的 容器2 0具與正常容器如瓶子一樣好的自支撐能力。所以， 具抗底面而垂直形成的經摺疊吊具要隱藏在底部部分的習 知容器的問題，如由經摺疊部分的彈簧彈回所引起的吊具 突出，失去自支撐穩定性，及倒落可被解決。當容器2 0以 上方朝下而使用時，如在第8圖所說明，一對環可自底面 向上彎曲，與具射出成型於預型底面的單一環的吊具相 較，具一對環的吊具1 0 a在強度上較佳，因為兩個環皆係 掛在掛鉤上。 而且，即使在圖式中所說明的具體實施例提供一對割 型11、11 ，在該預型10的直徑為大的及該吊具10a的長度 符合該預型1 0的突出之情況下，該預型1 0及該吊具1 0 a可 自射出孔穴1 2取出，故單型塊可用做該射出孔穴型1 (未說 明）。所以，根據本發明該射出孔穴型未限制於使用一對 割型如在圖式中所說明。Page 15 200530006 V. Description of the invention (9) Hanging, as illustrated in Figure 8 or 9. After molding, the sprue protruding from the center of the spreader 10a is cut off and removed from the neck. The spreader 10a at the bottom of the container 20 does not protrude from the base. Because the spreader 10a is hidden at the bottom of the annular recess, even the container 20 with the spreader at the bottom is as good as a normal container such as a bottle. Supporting capacity. Therefore, the problem of the conventional container in which the folded spreader with the bottom surface is formed vertically should be hidden in the bottom part, such as the spreader's protrusion caused by the spring rebound of the folded portion, loss of self-supporting stability, and falling Can be resolved. When the container 20 is used with the top down, as illustrated in FIG. 8, a pair of rings can be bent from the bottom to the top. Compared with a sling having a single ring that is molded on a preformed bottom surface, the pair of rings has a pair of rings. The spreader 10 a is better in strength because both rings are attached to the hook. Moreover, even if the specific embodiment illustrated in the drawing provides a pair of cut patterns 11, 11 in the case where the diameter of the preform 10 is large and the length of the spreader 10a matches the protrusion of the preform 10 The preform 10 and the spreader 10a can be taken out of the injection hole 12, so a single block can be used as the injection hole type 1 (not described). Therefore, the injection hole pattern according to the present invention is not limited to the use of a pair of cut patterns as illustrated in the drawings.
