Joint container

The purpose of the present invention is to provide a joint container for a container can, which is particularly useful for an activated carbon canister that is mounted on a car or motorcycle. The joint container is an intermediate product/semi-finished product made of activated carbon can or the like, which has a unique structure, and can be exposed to the canister without burrs when the subsequent welding process is performed to form the final product of the activated carbon can. The outer surface. The technology of the present invention can also be applied to a plastic container tank such as a lawn mower or a generator that is not limited to an activated carbon can.

For example, an activated carbon canister for a gasoline engine such as a car or a motorcycle is used to temporarily store the activated carbon stored in the evaporated oil. Then, when the car is driving, it will pump the oil back to the engine to burn.

In order to manufacture activated carbon cans for automobiles or locomotives, a joint container is required. The joint container includes a body and a cover member that are coupled to each other. The body and the cover member are connected by a contact flange to form a casing. In the known conventional art, the contact flanges are planarly joined. In the joint container, activated carbon, a non-woven fabric for preventing the toner from being exposed, and some separators are placed. After the toner is loaded into the container, the final work is to weld the joint body along the joint interface of the lid and the contact flange of the body to form a closed carbon can.

Figure 1 shows the structure of the joint container 1 used in the applicant's past activated carbon canister process. It should be stated that the structure of Figure 1 is used internally by the applicant but has not been disclosed and has only been a business secret in the past. This joint container 1 includes a body 2 and a cover member 3. Contact between the body 2 and the contact flange 4 of the cover member 3 On the surface, the body 2 is provided with a shallow bump 5 and a small recess 6, and the cover member 3 is provided with a deep groove 7 at a position corresponding to the shallow bump 5.

When the main body 2 and the lid member 3 are combined with each other to form the joint container 1, the joint container 1 is welded, preferably by spin welding. When welding, the contact flange 4 is melted along the material of the contact surface of the body 2 and the cover member 3, and the gap between the small recess 6 and the deep groove 7 and the shallow bump 5 can accommodate a part of the melting. The material, while the excess molten material diffuses along the contact surface and flows out of the outer side of the contact flange 4, while a large amount of burrs are formed in the vicinity of the outer contact portion 8 of the body 2 and the contact flange of the cover member 3.

In this technique, the molten material must be sufficient to ensure that the body 2 and the cover member 3 are tightly fitted. Therefore, raw edges are unavoidable. However, the raw edges cause a poor visual appearance and may cut the user. Therefore, in the art of Fig. 1, after the combined joining container 1 is welded, the obtained carbon can has a large amount of burrs, so that the carbon can is processed later to remove the burrs. The commonly used post-processing method is to use rotating equipment and tools to eliminate the burrs.

Although post-processing can beautifully eliminate the burrs, it will increase the time and equipment of many operations, thus increasing the cost of manufacturing activated carbon cans. On the other hand, the molten material has a melting effect at a temperature, which can enhance the adhesion of the canister, but the conventional technique does not provide a good joint structure to accommodate/guide the molten material, resulting in the molten material being exposed to the outside. The burrs, which must be removed, are really wasteful. Therefore, it is necessary to provide a joint container having a new joint structure to improve the aforementioned drawbacks.

The purpose of the present invention is to provide a joint container for use prior to fusion bonding. The joint container is a semi-finished product of the final product of a container such as an activated carbon can, which can be formed after the welding process. The joint container not only improves the past outflow of the molten material to form a burr, but also increases the bonding strength of the activated carbon can or the like.

The joint container is generally constructed as a casing including a cover member and a body that are coupled to each other for fusion. After the fusion bonding, the casing is exposed without burrs, so that the prior art eliminates the need for post-processing to remove the burrs and reduces the manufacturing cost.

According to an embodiment of the present invention, the cover member has a first engaging portion; the body has a second engaging portion. The first joint portion includes a base portion, a stopper extending from the base portion toward the second joint portion, and an installation space formed between the base portion and the stopper. The mounting space can receive the second joint and allow the second joint to be secured in a mounting position. The second engaging portion includes a base portion, and one of the retaining walls on one side of the base facing the stopper. When the second joint is fixed in the mounting position, a melt space is left between the bases to accommodate the molten material.

The advantages brought by this case include: (1) increase the strength: if the burr is left inside, it is equal to the adhesive, which will make the adhesion effect better; while the past burrs are exposed, not only affecting the appearance, but also removing it is a waste. . (2) The disadvantage of improving the appearance of the burrs and making the appearance look bad.

As shown in FIG. 2, the inventive joint container (10) includes a cover member (100) and a body (200). The cover member (100) and the body (200) are combined with each other to form a housing. The material of the housing is made of general plastic material. There is a joint container (10) The space can be placed such as activated carbon, non-woven fabric to prevent the toner from being exposed, and some partitions. The joining container (10) can be made into an activated carbon can after further performing a welding step.

The first joint portion (110) forms a portion of the cover member (100) and the second joint portion (210) forms a portion of the body (200).

The first joint portion (110) includes a base portion (120), a stopper (130) extending from the base portion (120) toward the second joint portion (210) of the body (200), and a base portion (120) formed at the base portion (120) ) and the installation space between the stops (130). The angle between the base (120) and the stop (130) defining the installation space is a preferred embodiment, about 90 degrees, although other suitable angles may be used as desired. The installation space can receive the second joint (210) in a mounting position. The second joint portion (210) includes a base portion (220) at one of the retaining walls (230) on one side of the base portion (220) facing the stopper (130). Combination cover (100) and body (200), the first joint portion (110) and the second joint portion (210) are relatively moved to allow the second joint portion (210) to enter the installation space until the second joint portion (210) arrives and/or Or fixed to the installation location. When the second joint (210) arrives and is fixed in the mounting position, a melt space (140) is left between the base (120) and the base (220) to accommodate the molten material. In the embodiment of the present invention, the melt space (140) is a part of the installation space. The stopper (130) is substantially abutted against the retaining wall (230) to prevent the melt from flowing between the stopper (130) and the retaining wall (230). The length of the stop (130) extends to at least a portion of the barrier wall (230) and preferably extends the entire length of the barrier wall (230) to provide better shielding against possible melt flow.

As shown in the embodiment of Fig. 3A, the base (220) is provided with a long projection (224) (male member) which is meltable during the welding process. Therefore, when the base (220) enters the installation space to reach/located in the installation position, a front end of the long protrusion (224) abuts against the base (120), and allows the melt space (140) to exist at the base (120). ) and between the base (220).
