DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap for opening and closing an opening of a container for storing detergent, cosmetics, toothpaste, and other fluid contents, particularly for an inverted container having a high fluidity of the contents. It is about the cap.

[0002]

2. Description of the Related Art Conventionally, as a cap for opening and closing with a single touch with a container cap, there is known an integral cap having an overcap connected to a cap body at a hinge portion.
It is used without losing the cap when opening.
In this container cap, a pin-shaped inner plug member and a cylindrical guide sleeve that fit into the spout are used for the overcap to prevent the overcap from opening and prevent leakage of contents and aroma. A mechanism is provided to protrude, seal the spout simultaneously with capping, cover the spout, and fit and lock.

However, in the example in which only a pin-shaped inner plug member fitted to the spout is provided in order to seal the spout, leakage is incomplete, and the contents adhere and become dirty. When the cylindrical guide sleeve that covers the periphery of the spout is protruded with the inner plug member, the contents easily accumulate in the guide sleeve, and the closed space is filled with the contents. The cap does not close properly due to the cushioning effect, and the fitting and locking is incomplete, affecting the contents and contaminating the mouth.When the contents are chewed, the fitting and locking operation is firm There is a problem that the cap is difficult to open, and the cap is in an open state. In particular, there is a drawback that the problem becomes more serious when the container is used for inverted use and the content is high in fluidity.

[0003] The present invention is intended to easily eliminate these conventional disadvantages, and even if an inner plug member fitted to the inner and outer peripheries of a spout provided in a cap and a guide sleeve at the mouth are provided. Caps do not close with the contents stored in the sleeve, can be securely fitted and locked, can be opened and closed easily, and can be used effectively as a container cap for inverted use Simple and inexpensive It is intended to be able to be manufactured at a high speed.

SUMMARY OF THE INVENTION The present invention provides a container cap which can be fitted to a container mouth A and has an overcap 4 which can be opened and closed via a hinge 3 on a cap body 2 having a spout 1. in the Notes to opening 1 ₁ of the outlet 1 while in a closed state overcap 4, for then projecting the guiding sleeve 6 on the inner surface of the overcap 4 to form a space ₆₁ around the spout 1 Guide the sleeve 6 and the spout 1 and the engaging locking structure, moreover some with a communicating path 11 communicating with the space _61.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In this container cap, a pin-shaped inner plug member is formed on the inner surface of the overcap, and a cylindrical guide sleeve is formed around the inner plug member. The fitting projection of the guide sleeve is fitted and locked to the ring-shaped projection on the outer periphery of the spout of the cap body, but the contents are filled in the closed space between the spout and the sleeve. Even if it accumulates, the cap is properly closed without the contents escaping from the communication passage and being filled, so that the contents can be used safely without affecting the contents.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment of the present invention will be described with reference to FIGS. 1 to 5 by way of example via a hinge 3 to a cap body 2 having a spout 1 which can be fitted to a container mouth A of a container body B. a container cap having freely open and close the overcap 4, while in the closed state an opening 1 ₁ of the spout 1 with the overcap 4, the guide sleeve 6 to form a space ₆₁ around the spout 1 communicating path 11 which a guide sleeve 6 and the spout 1 and the engaging locking structure projecting from the inner surface of the overcap 4, yet communicates with the space 6 ₁
The space does not escape from the communication passage 11 and the contents are filled in the closed space, so that the cushioning effect does not occur, and the cap is accurately and easily closed and used. .

[0007] In this case, the spout 1 has an opening 1 ₁ tapered, internal stopper member 5 of the tapered pin in the opening 1 ₁ a closing of the over cap 4 is fitted, to be sealed However, it is also possible to omit the inner plug member 5 so as to seal the inner surface of the overcap, and to attach the guide sleeve 6 to the ring-shaped protrusion 10 provided on the outer periphery of the spout 1. A ring-shaped fitting ridge 16 protruding from the inner periphery of the lower end is fitted and locked. The sleeve 6 including a part or a part of the fitting ridge 16 of the guide sleeve 6 is notched. A communication path 11 composed of a part is provided.

As shown in FIG. 3, the communication passage 11 can be formed by notching an undercut portion, as shown in FIG. 3. However, as shown in FIGS. The projection 16 may be a cut-out portion or a guide sleeve 6 as shown in FIGS. 3c and 3d.
Fitting convex portion and the cutout portion 11 ₂ formed 16, Note notch 11 provided in a ring shape protrusion 10 protruding from the outer periphery of the outlet 1
₁ and the communication passage 11 can be formed.
The contact portion with the sleeve for id 6 or other appropriate portions are selected and provided. Further, when the fitting projection 16 is fitted to the spout 1 with a gap, the ring-shaped projection 10
It may be the communication passage to form a notch 11 ₁ only.

The communication passage 11 is preferably formed at a position on the hinge 3 side where the container cap 2 and the overcap 4 are connected. The overcap 4 is connected to the cap body 2 by a hinge portion 3 and a pair of spring hinge portions 13 provided on both sides of the hinge portion 3. has a concave portion 14, each other to constitute a mounting surface is a container main body B of the flange portion 4 ₁ of inverted placed on the,
It is to allow one-touch opening of overcap 4 in the finger hook to the flange portion 4 _1.

The main body of the cap 2 has a stepped portion 7 formed on the upper surface to make it easy to cover the overcap 4 and has an opening fitting groove 12 on the inner periphery. The spout 1 is provided in communication with the inside of the container body.

In the present invention, the following characteristic configuration is also included in the present invention. An inner plug member 5 and a guide sleeve 6 fitted on the inner and outer circumferences of the spout 1 project from the inner surface of the cap body 2, and a fitting formed on the outer circumference of the guide sleeve 6 and the spout 1. A container cap provided with a communication passage 11 formed of a notch in a contact portion with a locking ring-shaped protrusion 10. A ring-shaped fitting ridge 16 protrudes from the inner periphery of the lower end of the guide sleeve 6 and is fitted and locked to a ring-shaped projection 10 protruding from the outer periphery of the spout 1.
