BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bottle container having an injection molding apparatus and a bottle ring,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bottle container having a bottle ring injection mold apparatus and a bottle ring, and it is possible to obtain an injection bottle having high quality by improving an injection mold stuck only to a conventional mass production purpose. The present invention relates to a bottle container which can be used more hygienically.

Injection molds are commonly used to inject a melt of synthetic resin, such as plastic, to produce a large quantity of products of the same specification. It has the advantages of high dimensional accuracy of production products and parts, compatibility with the same product standard, easy assembly and production, and the use of molds in the production of products can produce products without special skill or skill. These injection molds are also used for the production of bottle lings. Bartling is a component that serves to connect the bottle and the nipple to each other. Such batting rings should satisfy the heat resistance test of 200 ° C / 8hr in terms of characteristics, and in particular, there should be no weld lines to be formed in the inside, such as stamping, scratching and injection.

However, existing molds are arranged with more than 4 cavities so that they only focus on the purpose of mass production. Frequent occurrence of claims due to dimensional defects, loss of raw materials due to application of pin point gate, and crushing for raw material reuse There is a problem that the processing cost is increased.

In addition, the gate size of the mold design is increased during the mass production of the mold design, so that the weight of the bottling is not constant, so that the tolerance of the product is increased, resulting in the problem of the bottle and the assembly failure.

In addition, as shown in Fig. 1, the battle ring is a fatal defect in the weld line and the weld line generated on the inner surface of the outer surface. In case of containing the contents (for example, baby food) in the bottle container, The contents to be buried in the line are not easy to wash and eventually cause a problem of propagation of food poisoning bacteria.

Therefore, there is a disadvantage in that it is not easy to obtain a bottling of a good product and to provide a hygienic bottle container using the same.

FIG. 15 is a cross-sectional view taken along line A-A 'in Fig. 16 is a perspective view showing the support layer and the cover layer in Fig. 17 is a cross-sectional view taken along line B-B 'in Fig. FIG. 18 is a view showing the fixed layer and the third pillar layer of FIG. 14. FIG.

14 to 18, the composite sheet 130 includes a support layer 1320 having one or more first openings and made of a polymer resin; A first filler layer 1330 made of epoxy laminated on one side of the support layer 1320 and having a filler; A graphene film layer 1340 provided on the first pillar layer 1330; A second filler layer 1350 formed on the graphene film layer 1340 and made of epoxy having a filler; A graphene oxide film layer 1360 provided on the second pillar layer; A third pillar layer 1370 formed on the graphene oxide film layer 1360 and made of epoxy having a filler and graphene oxide particles; A fixing layer 1380 provided on the third pillar layer 1370 and having an adhesive force; And a film layer 1390 provided to cover the fixed layer 1380.

Generally, an electronic apparatus includes a plurality of electronic elements, and each electronic element generates heat while using electric energy. At this time, if the generated heat accumulates, it accelerates the aging of the electronic device, and in the worst case, it causes safety problems such as explosion, so it is necessary to radiate heat so that generated heat is not accumulated. BACKGROUND ART [0002] Recently, according to the multifunctional and slim performance of electronic devices, a plurality of various electronic devices are built in a small-sized electronic device, and the generated heat not only affects neighboring electronic devices, Are mutually amplified to further promote the temperature rise, so that the heat dissipation of the electronic device is more important. In addition, similar to the heat dissipation of the electronic device, the electromagnetic waves generated from the respective electronic devices are superimposed, so that there is a growing demand for shielding electromagnetic waves together with heat dissipation.

The composite sheet 130 according to the present embodiment is provided in a size appropriate for a slim and integrated electronic device, and can effectively perform electromagnetic shielding as well as heat radiation. The composite sheet 130 can be deformed in various forms and can effectively absorb heat and absorb electromagnetic waves even in a small size.

The supporting layer 1320 may be formed as a sheet having one side and the other side and a first pillar layer 1330 and a graphene film layer 1340 in a first direction (x direction) A second pillar layer 1350, a graphene oxide film layer 1360, a third pillar layer 1370 and a pinning layer 1380 are successively stacked on the other surface of the support layer 1320, A cover layer 1310 covering the outer surface of the cover layer 1310 may be provided. Further, a film layer 1390 provided to cover the fixed layer 1380 may be provided on the fixed layer 1380. The film layer 1390 may be formed of, for example, a synthetic resin film such as a polyethylene terephthalate (PET) film or a polyethylene (PE) film treated with a silicone or fluorine releasing agent and paper. The film layer 1390 is provided on the fixing layer 1380 and serves as a support for protecting the adhesive surface until the fixing layer 1380 is used. The fixing layer 1380 is coated with a silicone or fluorine releasing agent , The fixing layer 1380 may be provided so as to be naturally peeled without being damaged.

As the releasing agent to be provided in the film layer 1390, the fluorine-based releasing agent is preferable. The fluorine compound constituting the fluorine-based releasing agent has good non-tackiness properties and can impart lubricity to the film layer 1390 and thus has excellent releasability when the film layer 1390 is removed from the pinning layer 1380 . In addition, since it is a non-silicon system other than a silicon system, it is possible to prevent the occurrence of conduction failure even in application to an electronic device.

8 is a cross-sectional view taken along the line A-A 'in Fig. The composite sheet 130 according to an embodiment of the present invention includes a cover layer 1310 provided on the outermost surface and first to third pillar layers 1330 for controlling heat and electromagnetic waves generated in the electronic device, 150 and 170 and a graphene film layer 1340 and a graphene oxide film layer 1360 interposed between the first to third pillar layers 1330,

The first to third pillar layers 1330, 1350, and 1370 may include a polymer resin and epoxy and a filler dispersed in the epoxy. For example, the filler may include at least one of aluminum oxide (Al 2 O 3), boron nitride (BN), aluminum nitride (AIN), and silicon carbide (SiC). Preferably, the filler may be aluminum oxide (Al2O3). The first to third pillar layers 1330, 150, and 170 may be formed by mixing and dissolving epoxy with a solvent such as NMP, mixing and stirring the aluminum oxide to prepare a solution state, and then defoaming the slurry to form a slurry state For example, a sheet (film) using a bar coater or the like, followed by drying in a dry oven.

The thermal conductivity of the epoxy in the first through third pillar layers 1330, 1350 and 1370 may be approximately 0.2 W / mK and the thermal conductivity of the aluminum oxide may be approximately 40 W / mK. Since the first to third pillar layers 1330, 150, and 170 are provided to emit heat generated in the electronic device, the higher the content of the filler having a high thermal conductivity (e.g., aluminum oxide), the more effective the heat dissipation. Meanwhile, since the first to third pillar layers 1330, 150, and 170 must be effectively attached to the electronic device with the composite sheet 130 and function as a support for the pillars, a flexible and elastic epoxy is preferably used in a predetermined content range . It is preferable that the epoxy content of the first to third pillar layers 1330, 150 and 170 is 2 wt% to 7 wt%. If the epoxy content is less than 2 wt% , 150, and 170, and cracking or the like may occur during molding in a sheet or film shape. When the amount of the filler is less than 7 wt%, the epoxy may sufficiently function as a support. The efficiency of the heat radiation function may be lowered.

In addition, the filler may include a filler having a rectangular shape and a filler having a spherical shape. The filler having a rectangular shape and the filler having a spherical shape can increase the total surface area of the filler distributed in the epoxy in relation to the epoxy, so that the heat release can be effectively performed. The first to third pillar layers 1330, 150, and 170 may be formed in a sheet shape corresponding to the support layer 1320, and the third pillar layer 1370 may extend in a first direction And a protrusion 1371 protruding from the protruding portion 1371. The protrusion 1371 may further include a graphen oxide 1372 on the inner side of the protrusion 1371. The protrusion 1371 may penetrate the pinning layer 1380 to directly contact the electronic device on which the composite sheet 130 is mounted . Therefore, since the protrusion 1371 of the third pillar layer 1370 can receive real-time heat directly from the electronic device, heat accumulation in the electronic device and heat transfer to the surrounding electronic device can be effectively prevented.

The composite sheet 130 according to the present embodiment may include a graphene film layer 1340 and a graphene oxide film layer 1360 sandwiched between the first to third pillar layers 1330, have. The graphene film layer 1340 and the graphene oxide film layer 1360 are formed in the form of a film using graphene and graphene oxide, The efficiency of heat dissipation and electromagnetic shielding can be maximized. The first to third pillar layers 1330, 150, and 170 have elasticity and correspond to the graphene film layer 1340 and the graphene oxide film layer 1360, Layer 1340 and the graphene oxide film layer 1360 as shown in FIG. The graphene film layer 1340 and the graphene oxide film layer 1360 in the form of a film may be problematic due to low mechanical strength such as breakage due to external force. In the composite sheet 130 according to the present embodiment, The layer 1340 and the graphene oxide film layer 1360 are sandwiched between the first to third pillar layers 1330, 150 and 170 having elasticity to form the first to third pillar layers 1330 and 150 And 170 can act as a buffer to absorb an external impact, thereby effectively protecting the graphene film layer 1340 and the graphene oxide film layer 1360. Even if at least a part of the graphene film layer 1340 and the graphene oxide film layer 1360 are broken, the graphene film layer 1340 and the graphene oxide film layer 1360 are formed in the first to third The graphene film layer 1340 and the graphene oxide film layer 1360 are not deteriorated because they are fixed in the space controlled by the pillar layers 1330, 150, and 170, respectively.

The composite sheet 130 according to this embodiment can be mounted in an electronic device requiring electromagnetic shielding and heat dissipation wherein the film layer 1390 is removed and mounted and fixed by the fixing layer 1380. At this time, the protruding portion 1371 of the third pillar layer 1370 passing through the fixed layer 1380 may be provided so as to be in direct contact with the electronic device. The graphene film layer 1340 and the graphene oxide film layer 1360 have functions of heat dissipation and electromagnetic shielding on both sides, It is highly effective for heat dissipation function. On the other hand, since the graphene oxide film layer 1360 has a better insulating effect than the graphene film layer 1340, the graphene oxide film layer 1340 is more advantageous than the graphene film layer 1340 for shielding electromagnetic waves.

Therefore, by providing the graphene oxide film layer 1360 close to the electronic device in the composite sheet 130, the electromagnetic wave can be effectively absorbed / shielded, and at the same time, the graphene film layer 1340 can be provided. It is possible to effectively dissipate heat along with the interruption of electromagnetic waves by effectively controlling the heat which is not radiated by the graphene oxide film layer 1360. Alternatively, at least one of the graphene film layer 1340 and the graphene oxide film layer 1360 may be coupled with a silane group. The silane group imparts a function to the graphene film layer and the graphene oxide film layer, and the thermal conductivity and the bonding force between the epoxy and the epoxy can be improved by the coupling of the silane group. Therefore, by using the graphene film layer 1340 and the graphene oxide film layer 1360 to which the silane group is coupled in the composite sheet 130, the heat dissipation effect can be improved, and the graphene film layer 1340, It is possible to improve the mechanical strength of the composite sheet 130 by improving the bonding force with the first to third pillar layers 1330, 150, and 170 in contact with the oxide film layer 1360.

For example, the coupling of the silane groups can be achieved by mixing / ultrasonicizing the graphene film layer 1340 and the graphene oxide film layer 1360 in an acid solution, then applying DI water, filtering and drying to form a graphene film layer 1340 (E.g., = O,? OH, -COOH) in the graphene oxide film layer 1360 and the graphene oxide film layer 1360 and the graphene oxide film layer 1360 ), Mixed with Si-epoxy resin and methanol, treated with acetic acid to adjust the pH to 4.5 to 5, and then dried to obtain a graphene film layer 1340 and a graphene oxide film layer 1360, Can be prepared.

The cover layer 1310 may cover the outer surface of the support layer 1320 so as to be provided on the outermost surface of the composite sheet 130 according to an embodiment of the present invention. The support layer 1320 and the cover layer 1310 are respectively provided with first and second openings 1321 and 1320 which penetrate in the thickness direction of the support layer 1320 and the cover layer 1310 and function as air passages and heat input / , 111 may be provided.

That is, the shape of the passage of the first opening 1321 is reduced from one surface to the other surface so that the first opening 1321 provided on the support layer 1320 is different from the first surface and the second surface, truncated cone, thereby releasing heat from the electronic device to effectively dissipate heat, and at the same time, the internal protection by the support layer 1320 and the insulation effect can be maintained.

The cover layer 1310 may include a second opening 1311 that covers the support layer 1320 and is spaced apart from the first opening 1321 in the other surface 1323 of the support layer 1320. The cover layer 1310 can prevent moisture and the like from entering the inside of the composite sheet 130 and the electronic element protected by the composite sheet 130 by mounting the composite sheet 130, For example, a polyurethane and a black pigment, wherein the black pigment is at least one of carbon black, black pigment, black dye, iron oxide, copper oxide, tin oxide and mixtures thereof, and materials known in the art are used . The cover layer 1310 may be provided on the outermost surface of the composite sheet 130 to protect the composite sheet 130. The cover layer 1310 includes polyurethane to prevent external moisture, thereby improving moisture resistance and water resistance of the composite sheet 130. The black pigment can improve the light shielding effect. The second opening 1311 provided in the cover layer 1310 may be formed to be smaller than the second opening 1321 so as not to overlap with the first opening 1321 provided in the supporting layer 1320, have. The second opening 1311 of the cover layer 1310 acts as a passage for air to discharge heat generated in the electronic device together with the first opening 1321 of the support layer 1320 to the outside, . That is, since the second opening 1321 is provided to be offset from the first opening 1311, air, heat and the like are discharged to the outside, while moisture, foreign matter and the like are prevented from being introduced from the outside.
