Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cap attached to a container, and relates to a cap that can prevent the contents of the container from leaking out from a pouring nozzle formed on the cap with one touch.

[0002]

[Prior art]

 Conventionally, a cap (first conventional example) attached to a container has a cap body and a lid, and a pouring nozzle for pouring out the contents of the container is formed in the cap body. The lid is provided so as to be openable and closable with respect to the cap body, and is configured to cover the pouring nozzle.

Further, in the invention described in Japanese Patent Application Laid-Open No. 64-58672 (second conventional example), like the first conventional example, a spout nozzle is formed in the cap body so that the cap body can be opened and closed. It has been proposed that a protrusion is formed on the lid portion provided and that the protrusion is fitted to the tip of the pouring nozzle when the lid portion is closed to close the pouring nozzle.

[0004]

[Problems to be solved by the device]

 In the above-mentioned first conventional example, in order to prevent the contents of the container from leaking from the pouring nozzle at the distribution stage, when the lid is closed, the inside of the pouring nozzle is capped with an inner plug to prevent the leakage, and the lid is not used during use. The inside of the container is opened, the inner plug is removed, and the contents are poured out from the pouring nozzle. For this reason, in the first conventional example, the operation of opening and closing the lid and the operation of attaching and detaching the inner plug must be performed separately, and the tight closing and closing of the pouring nozzle cannot be performed in one touch.

Further, in the second conventional example, although the pouring nozzle can be opened and closed with one touch at the same time by opening and closing the lid, the projection of the lid is fitted to the tip of the pouring nozzle at the time of opening the lid. However, it cannot be said that the pouring nozzle is sealed. Therefore, the contents may leak from the pouring nozzle when the lid is closed.

The present invention has been made in consideration of the above circumstances, and an object thereof is to provide a cap capable of closing and opening the pouring nozzle formed in the cap body with one touch.

[0007]

[Means for Solving the Problems]

 The present invention relates to a cap having a cap body having a spout nozzle formed therein and which can be mounted on a container, and a lid part connected to the cap body via a hinge part to open and close the cap body. At least one of the main body and the lid is provided with an elastic member that extends beyond the hinge to the other and can apply an opening force to the lid, and an inner ring is formed on the inner surface of the lid. The outer ring and the outer ring are concentrically formed, and the tip of the pouring nozzle is detachably fitted between the inner ring and the outer ring when the lid is closed.

[0008]

[Action]

 Therefore, according to the cap of the present invention, the inner tube and the outer ring are formed on the inner surface of the lid 12, and the tip of the spout nozzle of the cap body is detachably fitted to the inner ring and the outer ring when the lid is closed. Since it is attached, the pouring nozzle can be fitted between the inner ring and the outer ring by simply closing the lid, and the pouring nozzle can be plugged with one touch. Therefore, it is possible to prevent the contents of the container from leaking from the pouring nozzle.

Further, an elastic member is arranged on the cap body and the lid portion across the hinge, and since this elastic member gives an opening force to the lid portion, only the engagement between the lid portion and the cap body is released. The lid opens, and the tip of the spout nozzle is disengaged from the inner ring and outer ring, allowing the spout nozzle to be opened with one touch.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 (A) is a sectional view showing a closed state together with a container in an embodiment of the cap according to the present invention, and FIG. 1 (B) is viewed from the direction IB-IB in FIG. 1 (A). FIG. FIG. 2 is a cross-sectional view showing an intermediate state of the opening / closing lid of the cap of FIG. FIG. 3 is a sectional view showing an open state of the cap of FIG.

As shown in FIG. 1, the cap 10 is made of a thermoplastic resin by integrally forming a cap main body 11 and a lid portion 12 via a hinge 13. This thermoplastic resin is, for example, low-density polyethylene, linear low-density polyethylene, high-density polyethylene or polypropylene, and low-density polyethylene and linear low-density polyethylene are preferable.

When such a thermoplastic resin is used, the amount of deformation of the lid 12 becomes large and the lid can be easily opened as will be described later, and the lid 12 can be restored to its original shape immediately after the deformation. This is because, as will be described later, when the lid is closed, the airtightness of the space 25 surrounded by the cap body 11 and the lid portion 12 is improved, and the sealing performance of the pouring nozzle 20 is also improved.

In the cap body 11, double peripheral walls 15 and 16 are integrally formed on the lower surface outer peripheral side of the top surface 14. The wedge protrusion 22 is integrally formed on the inner surface of the peripheral wall 16. The mouth portion 18 of the container 17 is fitted between these peripheral walls 15 and 16, and the cap 10 is attached to the container 17. At this time, the wedge protrusion 22 engages with the tip of the mouth portion 18 to prevent the cap 10 from coming off the container 17. The container 17 is configured to be flexibly deformable and has a squeeze property.

In the cap body 11, the central portion of the upper surface of the top surface 14 bulges upward in the figure to form a hemispherical top surface portion 19. The pouring nozzle 20 is integrally formed on the top surface portion 19. The pouring nozzle 20 is configured to project outward with a predetermined inclination angle with respect to the top surface 14. The dispensing nozzle 20 communicates with the mouth 18 of the container 17 through the top surface 19 and the peripheral wall 15, and by squeezing the container 17, the contents (eg, liquid) in the container 17 can be dispensed. R.

A protrusion 23 is integrally formed on the outer peripheral portion of the top surface 14 of the cap body 11. The ridge 23 has a semicircular cross section, and is formed over the entire circumference of the top surface 14 except for the portion corresponding to the hinge 13. The ridge 23 is engageable with the inner peripheral edge 24 of the opening of the lid 12, and the lid 12 covers the cap body 11. At this time, the space 25 formed by being surrounded by the cap body 11 and the lid portion 12 is maintained in a substantially sealed state.

The lid 12 is configured to be openable / closable with respect to the cap body 11 by a hinge 13, and covers the top surface 14, the top surface portion 19 and the pouring nozzle 20 of the cap body 11 when the lid is closed. As shown in FIG. 3, an elastic member 26 is attached to the cap body 11 at a position corresponding to the hinge 13. The elastic member 26 is made of a rubber-like elastic body such as silicone rubber, and is installed so as to extend from the cap body 11 beyond the hinge portion 13 to the inner surface of the lid portion 12. The elastic member 26 exerts an urging force in the opening direction on the lid portion 12, so that the lid portion 12 can be opened by simply releasing the engagement between the inner peripheral edge 24 of the opening of the lid portion 12 and the protrusion 23 of the cap body 11. It is configured to open at a sufficient opening angle.

As shown in FIG. 1A, an inner plug 27 is formed on the inner surface of the lid portion 12 at a position corresponding to the front end 21 of the pouring nozzle 20 when the lid is closed. As shown in FIG. 1 (B), the inner plug 27 is formed by arranging an inner ring 28 and an outer ring 29 in a concentric state. When the lid 12 is closed, the tip 21 of the pouring nozzle 20 is detachably fitted between the inner ring and the outer ring 29, and the pouring nozzle 20 is hermetically closed (sealed).

A pair of guide walls 30 are formed integrally with the outer ring 29 so as to face each other. These guide walls 30 are provided on both the left and right sides of the hinge 13 in the direction of the axis 31. Even if the lid 12 swings in the left-right direction in the closing process of the lid 12 (FIG. 2), the inner ring is formed. 28 and the outer ring 29 are guided to the tip 21 of the pouring nozzle 20.

As shown in FIGS. 1A and 1B, the outer ring 29 is provided with a taper 32 on the inner peripheral edge 24 side of the opening of the lid 12. The taper 32 is formed between the guide walls 30. Further, the taper 32 is formed so as to be inclined from the outer peripheral surface side of the outer ring 29 toward the inner peripheral surface side so as to reduce the height of the inner peripheral surface. Therefore, in the initial stage of the lid opening process of the lid portion 12, the tip 21 of the pouring nozzle 20 relatively moves along the taper 32, and the tip 21 of the pouring nozzle 20 moves to the inner ring 28 and the outer ring 29. It is structured so that it can be easily separated from the space.

Next, the operation will be described. In the lid closing process (FIG. 3 → FIG. 1 (A)), a closing force is applied to the lid portion 12 against the biasing force of the elastic member 26. When the inner plug 27 reaches the pouring nozzle 20, as shown in FIG. 2, the portion of the lid 12 corresponding to the inner plug 27 is pushed by the pouring nozzle 20 and elastically deforms, and the inner ring 27 of the inner plug 27 is ringed. 28 and the outer ring 29 ride over the tip end 21 of the pouring nozzle 20. At this time, the guide wall 30 prevents the lid 12 from swinging to the left and right in the axial direction of the hinge 13. Then, at the same time that the inner peripheral edge 24 of the opening of the lid 12 is engaged with the ridge 23 of the cap body 11, the tip 21 of the pouring nozzle 20 is fitted to the inner ring 28 and the outer ring 29, and the pouring nozzle 20 is tightly plugged. Be done. In this way, the lid 12 is closed.

In the lid opening process (FIGS. 1 (A) to 3), when the flange portion 33 of the lid portion 12 is pushed up, the inner peripheral edge 24 of the opening of the lid portion 12 and the protrusion 23 of the cap body 11 are engaged. Come off. At this time, due to the elastic deformation of the lid portion 12, the tip 21 of the pouring nozzle 20 relatively moves along the taper 32 of the outer ring 29. Then, the inner ring 28 and the outer ring 29 of the inner plug 27 are disengaged from the pouring nozzle 20 by the urging force of the elastic member 26, the portion corresponding to the inner plug 27 of the lid 12 is elastically deformed, and the lid 12 is opened. To do.

According to the above-described embodiment, the inner plug 27 including the inner ring 28 and the outer ring 29 is formed on the inner surface of the lid 12, and the tip 21 of the pouring nozzle 20 of the cap body 11 closes the lid 12. In this state, it is detachably fitted between the inner ring 28 and the outer ring 29, so that the tip 21 of the pouring nozzle 20 is fitted between the inner ring 28 and the outer ring 29 simply by closing the lid 12. The pouring nozzle 20 can be sealed. For this reason, it is possible to prevent the contents in the container 17 from leaking from the pouring nozzle 20.

An elastic member 26 is provided on the cap body 11 and the lid portion 12 so as to straddle the hinge 13, and the elastic member 26 gives an opening force to the lid portion 12. Therefore, the inner peripheral edge 24 of the opening of the lid portion 12 is The lid 12 is opened only by releasing the engagement between the protrusion 23 of the cap body 11 and the tip 21 of the pouring nozzle 20 is disengaged from the inner ring 28 and the outer ring 29, and the pouring nozzle 20 is opened. Can be done with one touch.

Further, since the pair of guide walls 30 are formed on the outer ring 29 of the inner plug 27, even if the lid 12 swings to the left and right in the direction of the axis 30 of the hinge 13 in the closing process of the lid 12, these Guide wall 30 guides the inner ring 28 and the outer ring 29 to the tip 21 of the pouring nozzle 20. Therefore, the pouring nozzle 20 can be easily and reliably closed (closed).

Since the taper 32 is formed on the outer ring 29 of the inner plug 27, the tip 21 of the spout nozzle 20 can be easily separated from the inner ring 28 and the outer ring 29 during the opening process of the lid 12, The outlet nozzle 20 can be easily opened.

Although the elastic member 26 is attached to the cap body 11 in the above embodiment, the elastic member 26 is attached to the lid portion 12 and extends to the top surface 14 of the cap body 11. May be arranged.
