Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stopper for a container, which is suitable for being attached to the spout of a metal can container containing mainly salad oil, tempura oil, etc., and which achieves good sealing performance and This invention relates to a container closure that can be opened without the need for a special opening tool.

Conventionally, when pouring out edible oil etc. stored in a can, a can opener or the like is used to use an appropriately shaped spout drilled into a corner of the upper wall of the can.
After pouring out oil or the like from the spout, a stopper was attached to the spout to seal it. However, according to this method, the user has to use a can opener etc. to open the spout, which is very troublesome, and in some cases, a special can opener etc. is also required to open the spout. This made it extremely uneconomical. In addition, there were cases in which the plug itself was easily removed from the spout, or it was troublesome to attach and remove the plug from the spout.

Therefore, the present invention has developed an inlet that is used when injecting oil, etc. into can containers during manufacturing in factories, etc.
It is used as a spout to pour out oil, etc. from a can container when used at home, etc., and by fitting to this spout, it prevents oil, etc. from overflowing inside the can, and It should have good sealing performance, be easy to open without requiring a lot of force, and be durable enough to withstand repeated use by considering the robustness of the knob that is used when opening the bottle. The purpose is to prevent dust from adhering to the display and to make it sanitary.

An embodiment of the present invention will be described below with reference to the drawings.

The container stopper according to the present invention is mainly a metal can-shaped container K that also serves as an inlet for oil, etc. during manufacturing in a factory, etc., and an outlet for oil, etc., when used at home, etc. It is made of a hard synthetic resin material with a suitable degree of hardness so that it can be removably fitted into the spout L of the spout L.

That is, a fitting convex portion 2 having a top plate 1 and formed in a hollow shape with a cavity 6 inside and open at the bottom so as to fit into the spout L; An upper plate 7 is provided on the upper end of the peripheral wall 3 of the convex part 2 in a direction perpendicular to the peripheral wall 3 and is on the same plane as the top plate 1 of the fitting convex part 2, and an outer periphery of this upper plate 7. Skirt piece 8 hanging downward from the end periphery
In order to remove the stopper itself from the spout L, the stopper 9 is formed by extending a part of the upper plate 7 further outward, and has a generally arcuate planar tab 9.

In addition, the lower part of the peripheral wall 3 of the fitting projection 2 is bulged from the inside to the outside, and the fitting is formed to be slightly larger than the diameter of the spout L so as to match the ring-shaped protrusion M of the spout L. a mating ridge 4 with a jaw 5;
It is provided around the outer surface of the peripheral wall 3.

As shown in FIG. 3, a cutout groove 12 having a generally arcuate planar shape and arranged concentrically with the outer periphery of the upper plate 7 is cut on the lower surface of the upper plate 7 toward the knob 9. At the same time, a thin film-like broken film 13 having a flat arc shape is formed on the upper part of the upper plate 7 . That is, the rupture film 13 is arranged above the cutout groove 12, and the cutout groove 12 itself has a substantially V-shaped groove shape in cross section with the bottom narrower than the opening, as shown in the figure. Therefore, when the gripping tongue piece 9 is lifted upward, the breaking action moves upward from the deep bottom surface of the cutout groove 12, that is, from the bottom surface of the breaking membrane 13 to the upper plate 7.
The upper surface can be freely attached to the side. Furthermore,
A tear-off hole 14 is made in the center of the plane of the rupture membrane 13 , and when force is applied by pinching the tab 9 and lifting it upward, the rupture membrane 13 above the notch groove 12 will open in the cut-off hole 14 . The cutout groove 12 is formed so as to be sequentially broken toward both ends thereof. When the tearing film 13 is finished tearing, as shown in FIG. The parts are composed.

Further, a stop recess 10 having a circular planar shape and continuous with the notch groove 12 is formed at the end of the cutout groove 12 so as to be cut out from the surface of the upper plate 7.
It is possible to prevent the finger ring piece 11 obtained by breaking the ring 3 from being separated from the upper plate 7, and the resulting tearing and damage to the upper plate 7.

Next, to explain an example of the use of the present invention, after pouring oil etc. into the container K from the spout L in a factory etc.,
It fits into the spout L. At this time,
As shown in FIG. 2, the fitting jaw 5 of the fitting protrusion 4 comes into contact with the lower surface of the upper vessel wall N around the spout L, and the lower surface of the upper plate 7 comes into contact with the upper end surface of the ring-shaped protrusion M. By being held between the upper vessel wall N and the ring-shaped projection M by the fitting jaws 5 and the upper plate 7, the spout L is tightly closed.

When using this at home, etc., if you apply force by lifting the tab 9 upward with your fingers, the broken membrane 13 above the notch groove 12 will
The cutout groove 12 is sequentially broken from the cutout hole 14 toward both ends, forming an opening in the upper plate 7 and forming a finger ring piece 11 having a substantially C-shaped planar shape. By hooking your finger on the cap and applying further force to lift it upward, the fitting convex portion 2 and the spout L are disengaged, and the stopper can be removed from the container K. Then, the contents such as oil may be poured out from the opened spout L.

Therefore, since the spout L of the container K, which also serves as an inlet, is formed in the container K itself, there is no need to adopt a top plate structure that seals the entire upper part of the container K, which simplifies the work associated with sealing and reduces the work involved. In addition to improving efficiency, there is no need for a special cap solely for closing the spout L, resulting in great economic benefits.

In addition, since the removable fitting protrusion 2 is formed on the spout L, the spout L can be completely closed by fitting the fitting protrusion 2 into the spout L. .

An upper plate 7 is provided around the upper end of the peripheral wall 3 of the fitting convex portion 2 outward in a direction perpendicular to the peripheral wall 3, and a skirt piece 8 is provided vertically downward from the outer peripheral edge of the upper plate 7. This prevents deformation of the entire stopper, and also covers the entire outer periphery of the spout L, thereby protecting the spout L and making it sanitary.

A gripping tongue piece 9 is extended on the upper plate 7, and a broken membrane 13 obtained by a cutout groove 12 cut in a substantially arc-shaped plane is arranged near the gripping tongue piece 9 and provided on the upper plate 7. Therefore, the tearable membrane 13 can be broken by pinching the pinching tongue piece 9 with fingers and applying force while lifting it upward. Furthermore, by breaking the breakable film 13, an opening is formed in the upper plate 7 itself, and the finger ring piece 11 is also formed.
The finger ring piece 11 can be easily removed from the spout L by simply lifting it upward while applying force. is provided below the rupture membrane 13, and
Since the cross-sectional shape of the cutout groove 12 itself is narrower at the bottom than the opening, when the pinching tongue piece 9 is pinched and force is applied to lift it upward,
The cutout grooves 12 apply a certain breaking force to the breaking film 13, so that it can be cut and broken without requiring a large force. In addition, when the packaging is closed before being broken, the upper surface of the upper plate 7 is flat and does not have any depressions, so it does not get clogged with dust or other particles. It is ideal for storing edible liquids such as tempura oil.

Furthermore, since the broken membrane 13 is always broken when the bottle is removed from the spout L, it is possible to easily determine whether the bottle has been opened or not.As a result, if there is a broken membrane 13, the buyer can In contrast, it can be shown that the container K is unopened, the quality of the oil etc. contained in the container K can be guaranteed, and reliability can be obtained so that the container can be purchased with peace of mind. In addition, the rupture film 1
By providing the cut-off hole 14 in 3, the breakable membrane 13 can be easily broken with a small amount of force.

In particular, when the fitting protrusion 4 is provided around the fitting convex portion 2 and the fitting jaw portion 5 is provided around the fitting protrusion 2, the fitting protrusion 4 is locked to the lower surface of the upper vessel wall N around the spout L, and unexpected It is possible to more effectively prevent the plug from easily coming off due to a fall or the like.

On the other hand, by molding the fitting protrusion 2 itself into a hollow shape having a cavity 6, elasticity is exhibited when it is attached to the spout L, and not only does it save molding material, but it also When the invention stopper is used as an outer stopper in combination with an inner stopper 20, which will be described later, it is also useful for protecting the finger ring 29 thereof.

Furthermore, it is also possible to use the plug body according to the present invention as an outer plug in combination with an inner plug 20 made of a softer synthetic resin material to form a double-structured plug device. That is, as shown in FIG. 5, the inner stopper 20 has a fitting concave portion 22 fitted therein with the fitting convex portion 2, and also has a general shape that allows the entire outside to block the spout L. A locking protrusion 21 is formed in a bottom cylindrical shape and is in contact with the upper end surface of the ring-shaped protrusion M forming the spout L, and a locking protrusion is provided on the periphery of the opening end at the top of the locking protrusion 21. a flange 28 extending outwardly in a direction perpendicular to the peripheral wall 23 of the section 21;
and a finger ring body 29 connected to the upper surface of the bottom 27 of the locking protrusion 21 via a support piece 30 in order to remove the inner plug 20 itself from the spout L.

Further, the lower part of the peripheral wall 23 is bulged from the inside to the outside, and a locking ridge 24 having a locking jaw 25 formed slightly larger than the diameter of the spout L is attached to the peripheral wall 23.
3, and a fitting groove 26 into which the fitting protrusion 4 locks and fits is provided around the inner surface of the peripheral wall 23.

In this way, the inner plug 20 is formed from a soft synthetic resin material, and the plug body of the present invention is formed from a synthetic resin material that is appropriately harder than the inner plug 20, thereby creating a double structure. The entire inner plug 20 becomes flexible and can be elastically deformed with a slight force, and the inner plug 20 can be easily attached to and removed from the spout L. In addition, the inner plug 20
When the outer plug is attached and removed, the outer plug itself is not deformed much because the hardness of the two is different, and the inner plug 2 is mainly deformed.
Since it is attached and detached by elastically deforming the inner plug 20, it becomes easy to attach and detach it to the inner plug 20. Moreover, when the inner stopper 20 is fitted into the spout L and the stopper body is fitted into the inner stopper 20,
The inner plug 20 is sandwiched and pressed between the ring-shaped protrusion M, which hardly deforms elastically, and the plug body, and is elastically deformed, and along with this deformation, an elastic force is generated.
If an attempt is made to remove both at the same time, the inner stopper 20 presses against the stopper, and the stopper presses against the inner stopper 20, and each prevents the other from deviating from the spout L at the same time. Therefore, there is no possibility that the oil etc. stored in the container K will overflow due to an unexpected situation such as an accidental fall. Moreover, the inner stopper 20 itself is tightly fitted into the ring-shaped protrusion M that forms the spout L.

Moreover, in this case, the plug itself as an outer plug is made of synthetic resin which is harder than the inner plug 20,
Even if the plug is lifted with the pinching tongue 9, only the plug is removed while the inner plug 20 remains fitted in the spout L, and both are not removed from the spout L at the same time.

Although the stopper according to the present invention is described and illustrated as being applied to a spout L formed in the upper wall N of a metal can-shaped container K for storing edible oil, etc. The container K is not limited to such a can-shaped container, but can of course be used even if it is a bottle, a sealed container, etc. made of glass, plastic, ceramics, etc., with the spout L covered. It is.

As explained above, according to the present invention, in a container that is closed in a substantially hermetically sealed manner to accommodate liquids and other various contents, a special cap-opening tool can be attached to the spout that also serves as an inlet. It can be opened easily without using a can opener or with a large amount of force, and it is very economical as it does not require a special can opener or other equipment. It is sturdy enough to prevent the upper plate from being cut or damaged more than necessary in some places, so it not only withstands repeated use, but also allows you to securely close the spout with the stopper itself, which prevents unexpected damage. In addition, the flat upper surface of the upper plate prevents it from becoming clogged with dust and other substances, making it hygienic. There is no need for a special cover, and furthermore, it is easy to attach and detach. It is easy to handle, has excellent handling, and has a simple and compact structure.
It has excellent effects such as being suitable for mass production.
