[Previous technology] As shown in FIG. 10 15 and FIG. 2, the existing container 4 includes a body 41 and a bottle mouth 42 formed at the top of the body 41. The bottle mouth 42 includes a joint formed on the body 41. The bottom convex ring 421 at the top of the body 41 is formed with a catch ring portion 422 formed above the bottom convex ring 421. The snap ring portion 422 has a plurality of convex teeth 4221 extending radially outward at intervals. Threaded portion 423 formed above the snap ring portion 422, a recessed ring portion 424 formed above the threaded portion, a reinforcing portion 425 formed above the recessed ring portion 424, and-closed The bundle is formed on the mouth above the milk of the reinforcing portion. An existing manufacturing method of the container 4 is mainly matched with a first mold 5 and a second mold 6 to sandwich the container blank (not shown in the figure, the front body of the container 4 is fixed). The mouth 426 ′ of the container 4 is supplied with air through the blow pin 7 by external pressure, and the first and second molds 5 and 6 are simultaneously molded to form the container 4. After the container 4 is formed, The reinforcing portion 425 of the excess material of the solid container 4 must be cut off before it is available—the bottle cap 8 (see FIG. 5) is capped on the bottle mouth 42 of the container 4. Although the container can be formed by cooperating with these molds and blow needles, and provide filling = mouth (such as fresh milk, fruit juices, etc.), in actual use, there are the following shortcomings. It is suspended inside the container 4 (the bottle mouth 42 position 20 at M260406). 'When the blowing needle 7 is penetrated into the container 4 for blow molding, the pressure of the blow molding is the same as that of the first and second molds 5 and 6. With the cooperation of the die, although the shape of each container 4 can be formed, the bottle mouth 42 is not fixed during the molding process. During the cooling process, it is easy to produce a recovery phenomenon, which leads to the true roundness of the bottle mouth 42. Not enough, and easy to cause leakage. 1. As shown in Fig. 3 and Fig. 4, the container blank of the front of the container 4 is composed of two pieces of material, and the mold is formed with the clamping a of the first and second molds 5, 6 (see Figure 丨). Later, a clamping line 43 (ie, flash) is formed at the mold clamping position and the cutting line L cuts off the reinforcing portion 425. The weak thickness of the concave ring portion 424 constitutes the top edge of the bottle mouth 42. A mold line 43 is formed on the outside of the ring portion 424 for moderate reinforcement, and after the beverage is loaded into the container 4, a layer of adhesive film (not shown) is sealed on the top edge of the concave ring portion 424. Cooperating with the heat molding and the bottle mouth, the leakage dead angle of the clamping line 43 protruding from the concave ring portion 424 will be completely sealed by the film body, and the beverage will not overflow, but after the film is removed When the bottle cap 8 is closed again, the protruding mold line 43 on the side of the concave ring portion 424 forms a leaky opening, that is, because the thickness of the top edge of the concave ring portion 424 is small, the bottle cap 42 The contact area with the concave ring portion 424 is not only small, but also when the operator wants to obtain a better degree of sealing by tightening the bottle cap 8 at the same time, when a tight stopper 81 is used for tight action The weak concave ring portion 424 is then depressed and deformed (see the concave ring portion 424 of FIG. 5), as shown in FIGS. 5 and 6, and the flexible plug piece 81 cannot deformly cover the deformation amount when it is simultaneously deformed. The clamping line 43 is held. Therefore, the clamping line 4 3 on the side of the concave ring portion 424 and the corners 4 31 on both sides of the concave line form an outlet for the beverage to leak out, as shown in FIG. 3, plus If the container blow-molded with a blow pin 7 is M260406, when the roundness of the bottle mouth 42 after molding is not enough, leakage will easily occur. In particular, the concave ring portion 424 will form a constriction near the clamping line 43 and cause The thickness of the second deformed part 4241, when the deformed part occurs, the leakage will be more serious. 5 [New content] Therefore, the purpose of this new model is to provide a blow-molded container with good roundness of the bottle mouth and less leakage, and a mold for forming the same. The novel blow-molded container and its forming mold include a body and a bottle mouth formed on the top of the body. The bottle mouth includes a bottom convex ring connected to the top of the body and a beam formed on the bottom. The snap ring portion above the convex ring '5 The snap ring portion has a plurality of convex teeth extending radially outwards at intervals, a threaded portion formed above the snap ring portion, and a closed portion formed by A concave ring portion above the threaded portion, a ring connection portion extending in a direction above the concave ring portion, the ring connection portion having a horizontal abutment surface, and an enlarged reinforcement formed above the ring connection portion And an opening is formed at the top of the reinforcing portion. [Embodiment] The foregoing and other technical contents, features, and effects of the present invention will be clearly understood in the following detailed description of a preferred embodiment with reference to the accompanying drawings. As shown in Figs. 7 and 8, one of the preferred embodiments of the novel blow-molded container and its forming mold is to use a forming mold to make a container 2 by blow molding. The container 2 includes a body 21 and a bottle mouth 22 formed at the top of the body 21, and the bottle mouth 22 includes a bottom protrusion 221 connected to the top M260406 end of the body 21-the beam is formed at the bottom Convex ring 222, which has a plurality of snap ring portions 222. The snap ring portion 222 has a plurality of radially extending outwards at intervals = convex teeth 2221, a threaded portion 223 forming a bundle above the snap ring portion 222. A concave ring portion 224 formed over the threaded portion 223, a wide flat shape ring connection portion 225 extending straight above the concave ring portion 224, and an enlarged portion formed over the ring connection portion 225 A reinforcing portion 226 is formed on the top of the reinforcing portion 226. The forming mold 1 has a first mold u, a first mold 12, and a blow mold nozzle 13 that press and hold the container 2. The blow mold nozzle I] penetrates into the bottle mouth 22 of the container 2 and has a main pipe section 131 abutting on the inside of the ring joint 225 of the bottle mouth 2 and a bundle of 13 pipe forward from the main pipe section 13 A front pipe section 132 extending and abutting on the inner side of the concave ring portion 224 of the bottle mouth 2, a rear pipe section 133 extending rearwardly from the main pipe section 131 and abutting on the opening 227 of the reinforcing portion 226, a through-hole The central through hole 134 of the present pipe section 131, the front pipe section 132 and the rear pipe section 133, and an air hole 135 which extends horizontally inward from the outer side of the main pipe section 131 and communicates with the central through hole 134, and the air hole 135 is provided. It is helpful for blow molding to guide the air flow around the bottle mouth 22 and accelerate the shaping of the meandering bottle mouth 22. Similar to the existing container molding method, the novel blow-molded container mainly uses two pieces of container blank (not shown, that is, the precursor of the container body) with the first and second molds 11 and 12 to nip and press, and The blow mold 13 is inserted into one of the mouths 111 and 121 of the first and second molds 11 and 12 so that the blow mold 13 is relatively located inside the bottle mouth 22 of the container 2. 13 Blow in the gas and cooperate with the clamping pressure of the first and second molds 11 and 12, that is, M260406 can form the container 2. At the same time, by the main pipe segment I) of the blow mold 13 against the inside of the ring joint 225 And by using the front pipe section 132 against the inside of the concave ring section 224, the ring joint 225 and the concave ring section 224 of the bottle mouth 22 are effectively fixed to maintain their true roundness, and then the rear pipe section 133 is used to bear against the The reinforcing part and the 5 open ports 227 are used for blow molding. Through the above description, the new blow molding container and its molding mold have the following effects and advantages, which are summarized as follows: As shown in Figure 8 and Figure 9, the new mold is positioned on the bottle by the blow mold. When the ring connecting part 225 and the concave ring part 224 of the mouth 22 are blow-molded into a] shape, and after cooling, the molding effect can be obtained by the pressure of the blow mold 13, so the bottle mouth 22 can be maintained. The perfect roundness prevents the container 2 from leaking. 2. As shown in FIG. 8, FIG. 9 and FIG. 10, after cutting the reinforcing portion 226 from the bottle mouth 22 along a cutting line B, the top of the ring-shaped portion 225 can be formed into a horizontal abutment surface 2251. Compared with the existing container, the area of the abutment surface 2251 is larger (about five times as large), and the ring joint portion 225 in the present case joins the concave ring portion 224 not only with a large thickness and better overall strength, which is sufficient to withstand The downward compressive force generated by the screwing of the bottle cap 3 without destroying the true roundness of the bottle mouth 22. When used, when the film (not shown) sealed on the top surface 2251 is torn off and then capped When the bottle cap 3 is shown in FIG. 10, although the deformation amount of a soft stopper piece 31 cannot completely cover the clamping line 23, the area of the abutment surface 2251 is large enough that the soft stopper piece 31 can The beverage overflow is completely blocked, so the clamping line 23 'located on the outside and occupying only one-fifth of the area of the abutment surface 2251 will not affect the sealing effect of the soft stopper 31 at all. Therefore, the case M260406 is impermeable The effectiveness and advantages of the leak, so the new model can effectively solve the lack of true roundness of the bottle mouth of the existing container, and easy to produce Leakage of the missing. It is worth mentioning that, similar to the existing container, although the container 2 in this case still has a clamping line 23 after molding, the ring connection portion 225 is provided in this case, and the ring connection portion 225 has a large area. The abutting surface 2251, so the formation of the 'clamping line 23' does not affect the quality of the locking of the bottle cap 3, so it is not easy to cause leakage. However, the above is only one of the preferred embodiments of the present invention. It cannot be used to limit the scope of implementation of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the new application for patents and the contents of the new specification. , All should still fall within the scope of this new type of patent.
