Description

[Detailed Description of the Invention] The present invention relates to a liquid spout stopper that is fitted into a spout of a container such as a bottle or can and used to pour out the liquid in the container.

Conventionally, many of these pouring stoppers have a connecting piece that connects the stopper body that fits into the container and the lid that closes it, but the connection between the stopper body and the lid is poor. There was a risk that the connecting pieces would break after many years of use.

In order to improve this, the applicant previously filed an application regarding a replacement stopper for containers (Utility Application No. 131515-1983).
There is still room for improvement in the structure of the lid, etc., and the present invention was devised in view of these issues.

That is, the purpose is to firmly connect the stopper body that fits into the spout of the container and the lid that closes the stopper body with the connecting piece, and to make the attachment of the lid more secure. To provide a liquid pouring stopper which is made strong and completely prevents liquid leakage and dust from entering.

The gist is that it consists of a stopper body that fits into the spout of the container, a lid that closes the stopper body, and a connecting piece that connects the stopper body and the lid. A substrate is provided, and on the bottom surface of this substrate, a cylindrical fitting part that fits inside the container spout and has an anti-separation edge around the outer peripheral surface, and a locking protrusion that fits outside the container spout and has a locking protrusion on the inner peripheral surface are formed. a cylindrical covering part, and a cylindrical spouting part communicating with the fitting part and a cylindrical locking edge around the spouting part on the upper surface of the substrate, On the other hand, the lid body has a side wall that is closely fitted into the spouting part, a cylindrical wall that is externally fitted to the locking edge, and is vertically disposed on the top plate, and the locking edge is attached to the inner opening of the cylinder wall. A locking stepped portion that locks the container is protruded, and a rush prevention portion is formed in the communication opening between the spouting portion and the fitting portion inside the spouting portion to partially obstruct the outflow of the liquid in the container, The connecting piece is formed by forming a thick raised part approximately in the longitudinal direction of a flexible strip, and one end of this connecting piece is connected to the cylinder wall near the top plate of the lid body at the other end. The parts are connected to the stopper body, and the connection is made such that the center line of the connecting piece coincides with the center of the stopper body and the center of the lid, and the thick raised part is connected to the stopper body so that the center line of the connecting piece coincides with the center of the lid. The length is such that when the body is closed, both ends of the connecting piece are perpendicular to the cylindrical wall as the mounting member and the stopper body, and when the lid is closed, the connecting piece is formed at both ends of the thick raised part. The entire body is bent into a substantially U-shape through the connecting piece, and furthermore, a handle protrusion is formed on the cylindrical wall portion on the opposite side from the cylindrical wall portion to which the connecting piece is fixed.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

The pouring stopper of the present invention includes a stopper body A that fits into the spout Y of a container It consists of C.

The ring-shaped base plate 1 of the stopper body A has a cylindrical fitting part 2 that fits into the spout Y of the container A cylindrical covering part 3 that is entirely covered is provided vertically.

The distance between the outer circumferential surface of the fitting part 2 and the inner circumferential surface of the covered part 3 is formed to be equal to the thickness of the spout Y, and the outer circumferential surface of the fitting part 2 is provided with a slip-off prevention edge 4 to prevent it from coming off. There are many surrounding areas.

Furthermore, locking protrusions 5 are formed at two opposing locations on the inner circumferential surface of the covered portion 3, and are configured to lock onto the spout Y.

On the opposite side of the substrate 1 is a cylindrical pouring part 7 coaxial with the fitting part 2 and having an enlarged opening edge 6 .

Furthermore, a locking edge 8 having a slight height is provided around the spouting portion 7, and the locking edge 8 is used for locking with a lid B, which will be described later.

Needless to say, both the spouting part 7 and the fitting part 2 are in communication with each other, and a rush prevention part 12 consisting of a disk 10 and a tripod 11 extends from the communication opening 9.

The rush prevention part 12 is located in the liquid passage in the container X, and has the function of partially obstructing the flow of liquid at the beginning of pouring, and keeping the pouring amount, pouring direction, etc. substantially constant.

One end of a flexible band-shaped connecting piece C having a predetermined length is connected to the covering portion 3 .

A thick protrusion 13 is formed on the longitudinal center of the connecting piece C, and an appropriate number of slits 1 are formed along the longitudinal direction.
4 is drilled.

The raised portion 13 increases the strength of the connecting piece C and also has an elastic restoring force that smoothes the opening operation of the lid body B connected to the other end of the connecting piece C.

It is desirable that this connecting piece C be formed relatively long.

One end of this connecting piece C is connected to the cylindrical wall 16 near the top plate 15 of the lid body B, and the other end is connected to the stopper body A, and this connection is made so that the center line of the connecting piece C is aligned with the stopper body A. Connect so that the center matches the center of the lid body B.

Further, when the lid body B is closed on the plug body A, both ends of the connecting piece C are attached to the cylinder wall 16 as a mounting member.
The connecting piece C is formed to have a length perpendicular to the stopper body A, and when the lid is closed, the connecting piece C is bent into a substantially U-shape as a whole through both ends of the thick raised part 13. It is.

The lid body B connected to the other end in the long plane direction of the connecting piece C includes a circular top plate 15, a cylinder wall 16 that is vertically disposed on the top plate 15, and forms a bottomed double cylinder together with the top plate 15, and side walls. It consists of 17 mag.

The side wall 17 forming the inner cylinder has an outer diameter equal to the inner diameter of the spouting part 7 so that it is closely accommodated in the spouting part 7 of the stopper body A, and prevents liquid from leaking near the spouting part 7. is definitely prevented.

In addition, locking step portions 18 having a substantially semicircular planar shape are provided around the inner edge of the cylinder wall 16 forming the outer cylinder so as to face each other.
By being locked to the locking edge 8, the lid body B is brought into close contact with the stopper body A to close the lid.

In addition, a handle protrusion 19 is formed on the cylindrical wall 16 so that it is easy to catch a finger when opening the lid.

If the connecting piece C is formed long enough as shown in the figure, the lid B can be lowered from directly above the stopper body A when the lid is closed, making it easier to close. Since it can be placed on standby at a position relatively far from the pouring part 7, there is no fear that the liquid to be poured will spill onto the lid B and stain the surrounding area, and there is an advantage that it can be used cleanly.

As shown above, the present invention is constructed such that on the lower surface of the substrate 1 of the stopper body A, there is a cylindrical fitting part 2 that fits inside the spout Y of the container Since a cylindrical covering part 3 is provided which fits over the spout Y of X and has a locking protrusion 5 formed on the inner peripheral surface, the fitting part 2 and the sheathing part 3 sandwich the spout Y. Therefore, the stopper body A can be firmly fixed to the spout Y.

Moreover, due to the synergistic action of the locking protrusion 5 and the anti-separation edge 4, liquid leakage and removal of the stopper body A can be completely prevented.

Further, a cylindrical spouting part 7 communicating with the fitting part 2 and a cylindrical locking edge 8 around this spouting part 7 are provided on the upper surface of the base plate 1 of the stopper body A. The top plate 1 includes a side wall 17 that fits inside the pouring part 7 closely and a cylindrical wall 16 that fits outside the locking edge 8.
5, and a locking step 18 that locks with the locking edge 8 is protruded from the inner rim of the cylinder wall 16, so that the locking step 18 of the cylinder wall 16 and the locking edge 8 are connected to the stopper body. A and the lid B can be firmly fitted together, and the lid B is prevented from shifting or coming off.

Moreover, due to the structure of the spouting part 7 and the side wall 17 that fits closely into the spouting part 7, liquid leakage can be completely prevented.

Furthermore, as shown in FIG. 4, since the cylindrical wall 16 and the side wall 17 sandwich the spouting part 7 and the locking edge 8 of the stopper body A, fitting of the lid body B onto the stopper body A is easy. It can be made stronger.

In addition, inside the spouting part 7, a rush prevention part 12 is formed in the communication port 9 between the spouting part 7 and the fitting part 2, which partially obstructs the outflow of the liquid in the container X. It is possible to partially obstruct the flow of liquid and keep the amount and direction of pouring almost constant, which prevents inconveniences such as accidentally pouring a large amount of liquid, and prevents the liquid from pouring out with too much force. The inconvenience of scattering outward is eliminated.

In addition, a locking edge 8 is formed around the pouring portion 7, and the lid B is closed and locked to the locking edge 8, so that the mouth edge of the lid B is relatively easily soiled. The part does not come into direct contact with the spouting part 7, so it can be used cleanly at all times.

A thick raised portion 1 is provided approximately in the longitudinal direction of the belt-shaped connecting piece C.
3, the strength of the connecting piece C is improved and it will not be damaged even if the lid body B is opened and closed frequently.

Not only that, but also because the elastic restoring force is imparted, this is combined with the structure in which the handhold protrusion 19 is formed on the portion of the cylinder wall 16 on the opposite side to the portion of the cylinder wall 16 to which the connecting piece C is fixed. , which allows for one-touch opening of the lid with one hand.

Moreover, since the connecting piece C is made of a flexible band plate, the lid body B does not move unstablely in the lateral direction when the lid is opened.

Therefore, when closing the lid, the lid B can be easily guided to the plug body A by pushing the lid B toward the plug main body A with fingers or the like.

In addition, since the center line of the connecting piece C is aligned with the center of the stopper body A and the center of the lid body B, it is extremely easy to align the lid body B with the stopper body A when closing the lid, and it can be done with one hand. operation is possible.

Furthermore, one end of the connecting piece C is connected to a cylindrical wall 16 close to the top plate 15 of the lid B, and the other end is connected to the plug body A, and the thick raised portion 13 connects the lid B to the plug body A. The length is such that both ends of the connecting piece C are perpendicular to the cylindrical wall 16 as a mounting member and the stopper body A when the lid is closed, so that when the lid is closed, the connecting piece C forms a thick raised part. Since the entire cover is bent into a substantially U-shape through both ends of the cover 13, it is even easier to close the cover with one hand.

That is, when closing the lid, the connecting piece C is first bent at the lower end of the thick raised part 13 due to the movement of fingers or the like, and then the connecting piece C is bent anew at the upper end of the thick raised part 13. Since the lid B can be easily guided to the stopper body A and the lid B can be guided from above, the lid can be closed very easily.

Moreover, even if the connecting piece C is made long to make it easier to close the lid, the thick raised portion 13 prevents the connecting piece C from twisting, so the lid can be reliably closed even with one hand. be.

In addition, since the connecting piece C is attached to the lid body B on the cylindrical wall 16 near the top plate 15, the degree of freedom for the lid body B with respect to the connecting piece C can be increased, and the lid body B can be attached to the stopper body A. Easy to operate.

As described above, the present invention dramatically improves the attachment of the stopper body A to the container, the tightness of the lid B when closing the lid, and the operability of opening and closing, and also improves the robustness of the connecting piece C. This allows for repeated use over long periods of time.In particular, the one-touch opening/closing operation with one hand can be performed reliably and easily, and the structure also prevents dust and liquid leakage to maintain cleanliness. It has various practical effects such as being simple and suitable for mass production.
