Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap for a container which can be applied to another object by directly applying the content to a container containing the contents such as liquid and viscous substance.

[0002]

2. Description of the Related Art When the contents such as liquid, viscous substance, and granules are taken out from a container filled with glass bottles or plastic bottles, the cap structure is simple in case of taking out the whole contents at one time. However, in general, a cap (cap having a reclosing function) that can be dispensed by the user is often attached to the opening of the container. Various types of caps that can be dispensed have been proposed and put into practical use.
For example, in the case of a plastic molding cap composed of two parts, the two parts are manufactured by molding different molds, respectively, and the two parts are combined to form a cap in a different process. The productivity was poor and the cost was high because of the necessity of the setting process. As a standpoint to use, the separate reclose cap is troublesome and troublesome. Further, if the cap is a separate body when the contents are dispensed and used, there is a risk that the reclose cap may be lost during use. Therefore, recently, an integrally molded cap has come to be widely used. Therefore, recently, an integrally molded hinge cap has been widely used so that the crown member is not separated from the cap lid member even when mounted on the container body and used. The structural elements of these integrally molded spouts are a lid member, a crown member, and a number member. That is, a lid member suitable for mutual engagement with the opening neck portion of the container body, a crown member for covering the spout when not in use during dispensing, and the lid member and the crown member are coupled to each other, A number member (hereinafter referred to as a hinge portion or hinge) designed to easily and surely move the member onto the lid member, which is integrally molded by injection molding using a plastic material. It is a thing. When pouring the contents from a container equipped with a hinge cap,
When simply dropping or dropping the contents, even if the hinge cap has a structure that does not interfere, when the contents are directly applied from the container to another object, in the conventional hinge cap structure, Since a part of the protrusion protrudes beyond the horizontal extension line of the tip of the spout, there is a problem that the object to be coated comes into contact during coating and the work cannot be performed. Therefore, in the past, despite of the disadvantages described above, there were many cases where the cap system was provided separately. There is a demand for a cap having a structure that allows convenience in use, that is, a structure in which the crown member is opened and can be applied to another object as it is with one hand.

[0003]

When the contents are poured from a container with a hinge cap filled with a liquid or a viscous substance and directly applied to another object, the cap which is opened does not hinder the application work. I will provide a.

[0004]

In order to solve the above-mentioned problems, the present inventor has invented the following hinge cap. The hinge cap comprises a lid member suitable for interengaging an open neck of a container and a crown member forming a final cap, said lid member and crown member respectively comprising a bottom wall portion and a skirt portion. A hinge cap having a mating surface in which the lower end of the skirt portion of the crown member and the bottom plate of the lid member are in close contact with each other when the crown member is in the closed position, the mating surfaces are inclined, and the respective skirt portions are inclined. A hinge cap having a pair of integral hinges projecting from the lowermost part of the slope, wherein the crown member includes a fixing device that locks and closes the lid member.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION A container to which a hinge cap is attached according to the present invention is a glass bottle, a plastic bottle or the like, the contents of which need to be dispensed and applied to another object. It is a viscous material and its specific uses include foods such as kneading spices and miso, hair dressings, ointments, shoe polish, toothpaste and other cosmetics, chemicals, hygiene products, industrial or household emulsion adhesives. Agents, etc. It is preferable that when the contents are dispensed, the spout is easily exposed, and after the contents are dispensed, the cap can be easily covered to close the spout. The hinge cap of the present invention fits or engages with the neck of the container to form the spout, and its structure forms a cap and a cap that can fit or engage with the neck of the container. The crown member and the integrally formed hinge that mutually engages the lid member and the crown member are integrally molded. The hinge cap of the present invention has a structure that can be molded by injection molding using a plastic material, and examples of the plastic material include low density polyethylene, medium density polyethylene, high density polyethylene, polypropylene, polyamide, polycarbonate, vinyl chloride. , Polyester, and the like. As the basic structure of the hinge cap C, as described above, the lid member that is screwed or fitted to the main body container, the crown member that covers the outer lid member, and the number member that connects the both members (hereinafter referred to as the hinge portion or the hinge). It is mainly composed of three parts.

As a method of mounting the hinge cap of the present invention on a container, for example, the lid member comprises a top plate having a spout and a skirt portion hanging from the outer periphery of the top plate.
A screw provided on the inner surface of the skirt portion of the lid member may be screwed with a screw provided on the outer surface of the opening of the container body, or the lid member may be capped on the neck portion of the container. The skirt portion has an outer annular body portion having a surface to be fitted with the skirt portion of the crown member, and a second skirt portion in a raised state inside the annular body. The second skirt portion hangs down from the periphery of the top plate having the spout. The mating surface of the crown member with the lower end of the skirt is inclined.

Next, the crown member integrally formed with the lid member by a hinge comprises a top plate and a skirt portion hanging down from the outer periphery of the top plate, and in the closed state, the skirt portion of the crown member. The lower end of the lid member is aligned with the upper end of the first skirt portion of the lid member, and the mating surface is the same inclined surface as the upper end of the first skirt portion of the lid member. , The structure is closely attached. In the present invention, the mating surface is provided with an inclination as described above. The crown member is released from the lid member by sloping the mating surface and by providing the hinge portion connecting the lid member and the crown member at the bottom of the slope, and the hinge member is stopped by the hinge cap. At any time, any part of the crown member can be below the horizontal line passing through the tip of the spout, so that when applying the contents directly from the container to another object, the crown member is not covered. There is no contact with the coated surface. The structure of the integrally-molded hinge cap portion according to the present invention can utilize the technology of the three-point hinge method, but as described above, any portion of the crown member opened at the time of use can pass horizontally through the nozzle tip. The hinge is not limited to the above-mentioned three-point hinge as long as it can be fixed under a straight line.

Next, the reclose will be described. The lid member and the crown member are reclosed after the required amount of contents have been discharged, but when the crown member is moved over the lid member by using the three-point hinge method, the hinge is restored. The force causes a close-closed state that is close to close contact. However, depending on the type of contents, a higher degree of adhesion may be required. Therefore, in the present invention, a minute projection is provided on the inner surface of the lower end of the skirt portion of the crown member, and A minute protrusion is provided near the lower end of the second skirt portion, and the protrusion provided on the lid member crosses over the protrusion provided on the crown member, resulting in an occlusal state,
The lid member and the crown member are securely locked. The minute protrusions may be provided on the entire circumference of the positions of both members,
It may be partially provided.

Again, in the method of opening the crown member at the time of dispensing, by pulling up the knob portion provided on the crown member skirt, the spring effect of the hinge causes the crown member to stop at a predetermined position. The contents can be applied to other objects directly from the exposed spout.

As described above, the hinge cap of the present invention may be attached to the main body container by a method such as fitting by screwing or tapping, and if necessary, fitting by screwing or tapping. A buffer sheet (packing) may be interposed between the opening of the container and the lid member at the time of joining to prevent leakage during transportation and storage, and may be removed at the time of first use. Alternatively, it is possible to supplementally sandwich the donut packing to prevent leakage from between the container body and the hinge cap. It is important to seal the spout provided on the top plate of the lid member when not in use, for example, under the crown member top plate, when the lid is closed, fit into the opening of the spout, and This can be achieved by, for example, providing a projection for sealing the spout that can be closely attached to the inner circumference of the exit.
