Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a lid for a wide-mouth container for packaging powdered products such as powdered milk and granular products, in which the contents are opened after the wide-mouth container is opened. When scooping with a spoon,
The present invention relates to a lid device capable of sliding the contents scooped up in a heap on a spoon flatly along the edge of the spoon.

[Conventional technology]

To take out a certain amount of powdered products such as milk powder packed in a wide-mouthed container, scoop up the contents once with a spoon of a certain volume and then slide the contents evenly along the edge of the spoon. It is well known that the cutting is done to scrape off the excess part, and in that case, the sliding of the contents scooped up in a spoon can be done using the lid for the wide-mouthed container. , Therefore, conventionally, the 7th
The means shown in FIGS. 8 to 8 have been adopted.

That is, this conventional means, by forming a thin weakening line 13 in a loop shape on the inner surface side of the lid body 12 made of a soft synthetic resin sheet or a metal plate attached to the mouth portion of the wide-mouthed container 11. An opening portion 12a is formed on the lid body 12, and a gripping piece 14 for opening is fixed to a part of the outer surface of the opening portion 12a close to the weakening line 13 by a rivet 15 to remove the gripping piece 14. In a so-called pull-open type lid body configured to tear and cut the opening portion 12a by pulling, by forming a linear portion 13a in a part of the loop-shaped weakening line 13, the opening hole 16 formed by opening. A linear portion 16a is formed on the inner peripheral edge, and at the linear portion 16a on the inner peripheral edge of the opening hole 16,
The content B scooped up on the spoon A was scraped off.

[Problems to be solved by the device]

However, as in this prior art, the opening hole in the lid 12
In the case where the inner peripheral edge of 16 is used for sliding, since the lid 16 has a small wall thickness, when the content B scooped up on the spoon A is slid off The parts are accumulated on the upper surface of the lid body 12, and the contents B accumulated on the upper surface of the lid body 12 are likely to be attached with dust or deteriorated by moisture, which is unsanitary and has an external appearance. There was a problem that it would get worse.

On the other hand, in Japanese Utility Model Publication No. 36-20077, an inner plug-like lid body formed by integrally molding a spoon adapted to be inserted into a bottle into a guide tube that is fitted into the bottle mouth so as not to fall is made detachable. It is described that a sliding plate extending obliquely downward is formed on the lower end of the guide cylinder while being fitted, and according to this configuration, the sliding plate is located in the bottle. Therefore, all the contents scraped off from the spoon are returned to the inside of the bottle, and therefore the above-mentioned problems of hygiene and aesthetics do not occur.

However, there is a problem that it is difficult to apply to the eye where a part for cutting (a guide cylinder) is separately fitted into the bottle mouth, for example, a wide-mouth container such as a can for packaging milk powder, and the structure becomes complicated. It was Further, if the guide tube is loosely fitted in the bottle mouth, there is a problem that the guide tube may come out of the bottle mouth when it is scraped off with a spoon.

[Means for Solving the Problems]

In order to achieve this object, the present invention provides "a lid made of a metal plate fitted in the mouth of a wide-mouthed container is provided with an opening hole of an appropriate shape, and a soft synthetic material for closing the opening hole. A resin-made closing plate body is integrally molded, the closing plate body is provided with a weakening line for forming an opening portion in the closing plate body, and the outer surface of the opening portion in the closing plate body is the above-mentioned. In a portion close to the weakening line, while integrally molding a gripping piece for the unsealing portion, on the inner surface side of the closing plate body, a portion located closer to the outer periphery of the closing plate body than the weakening line, The protrusion for scraping the spoon for scooping the contents in the wide-mouthed container is integrally formed so as to project into the inside of the wide-mouthed container. "

[Function and effect of device]

In this configuration, when the lid device is used to seal the wide-mouthed container and then the gripping piece is pulled, the opening portion of the closing plate is torn along the weakening line, so that the wide-mouthed container is opened with one touch. On the other hand, since the protrusion for sliding off the spoon for scooping the contents remains attached to the lid body even after opening, the contents such as powder or granules contained in the wide-mouthed container Scoop up with a spoon in a heap shape, apply the opening edge of the spoon to the tip edge of the projection for sliding, and slide the contents flat along the edge of the spoon to scrape off the excess part, A certain amount of contents can be taken out.

In that case, since the projection for sliding on the spoon projects toward the inside of the wide-mouthed container, all the contents scraped off from the spoon will return to the inside of the wide-mouthed container, in other words, scooped up in the spoon. Since the contents are scraped off inside the wide-mouthed container, the contents scraped off from the spoon do not accumulate on the outer surface of the lid body and cause problems in hygiene and appearance.

Further, the scraping projection is an integrally formed closure plate for sealing the lid, in other words, the scraping projection is provided by using the sealing means, and therefore, it is extremely suitable for a wide-mouthed container. It can be easily applied, and the structure does not become complicated due to the provision of the scraping projections.
Further, since the scraping-out projection is integrally formed with the lid, the scraping-out projection is never accidentally separated from the lid when the spoon is scraped off.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

First, FIGS. 1 to 4 show the first embodiment. In the first embodiment, reference numeral 1 is a wide-mouth container formed of an appropriate material such as metal or synthetic resin, and reference numeral 2 is the wide-mouth container. 1A and 1B respectively show a lid body made of a thin metal plate fitted in the mouth portion 1. The lid 2
A mounting portion 2a having an inverted U-shaped cross section, which is fitted into the mouth portion of the wide-mouthed container 1, is bent and formed on the outer peripheral edge of the mounting portion.
A packing 3 made of rubber or the like is applied to the inner surface of 2a.

Further, in order to close the opening hole 4 in the lid body 2, an opening hole 3 having an appropriate area is formed so that a part of the inner peripheral edge thereof becomes a straight portion 3a having an appropriate length. The closing plate body 5 made of a soft synthetic resin such as polyethylene is integrally molded.

Then, on the lower surface side of the closing plate body 5, a V groove 6 as an example of a weakening line is formed in a loop shape along the inner peripheral edge of the opening hole 4 so that the closing plate body 5 can be opened. Hole 4
While forming the unsealing portion 5a having a similar shape to that of the inner surface of the closing plate body 5, the peripheral portion 5b located on the outer side of the V groove 6 is scooped up with the spoon A after unsealing the powdered content. A plate-shaped sliding projection 7 for sliding off the object B is integrally formed so as to project inside the wide-mouthed container 1.

On the other hand, a pull ring 8 as an example of a gripping piece is provided on a portion of the outer surface of the unsealing portion 5a that is close to the V groove 6 (in the embodiment, in the vicinity of the connecting portion between the straight line portion of the weakening line 6 and the arc portion). Is integrally formed, and further, on the outer surface of the closing plate body 5,
A non-moisture permeable film such as aluminum foil is attached.

In addition, the closing plate body 5 is firmly fixed to the lid body 2 by bending the inner peripheral edge of the opening hole 4 in the lid body 2 in a U-shaped cross section, and the moisture impermeability is improved. Extend the peripheral edge 9a of the film 9 to the outside of the closing plate body 5,
This is attached to the outer surface of the lid 2.

In the above configuration, the mounting portion 2a of the lid body 2 is fitted to the mouth portion of the wide-mouthed container 1 by an appropriate means such as winding tightening or caulking, while the wide-mouthed container 1 can be sealed. By pulling the pull ring 8 upward to tear and cut the opening 5a along the V-groove 6, at the same time, the peripheral edge 9a of the moisture impermeable film 9 is peeled off from the peripheral edge 5b of the lid 2 and the closing plate 5. The wide-mouth container 1 can be opened with one touch.

And, even after opening, the slidable protrusions 7 have the wide-mouthed container 1
Since the contents B are still attached to the spoon A, the contents B are once scooped up in a heap shape, and the upper surface of the spoon A is applied to the tip edge of the slide-cutting projections 7 to be slid flat to scrape off the excess portion. As a result, the content B can be taken out with the spoon A in a certain amount.

In this case, since the slide-cutting projection 7 projects toward the inside of the wide-mouthed container 1, when the excess content B is scraped off by the spoon A, the content B scraped off by the slide-cutting projection 7 is removed. All return to the inside of the wide-mouthed container 1 and the contents B do not accumulate on the upper surface of the peripheral edge portion 5b of the closing plate body 5 or the upper surface of the lid body 2. Therefore, the hygiene condition deteriorates or the appearance is deteriorated after opening. It is possible to reliably prevent the deterioration.

Further, since the slide-cutting projection 7 is integrally formed with the closing plate body 5 for sealing the lid body 2, it can be applied to a wide-mouthed container without any trouble and the slide-cutting projection 7 The structure does not become complicated due to the provision of the above, and since the scraping projection 7 is formed integrally with the lid body 2, the scraping projection 7 is formed when the spoon A is slid. There is no accidental departure from 2.

In addition, when the non-moisture permeable film 9 is attached to the outer surface of the closing plate 5 as in the embodiment, the closing plate 5 is molded with an inexpensive soft synthetic resin having moisture permeability such as polyethylene. Moreover, even when the thickness of the closing plate 5 is small, the non-moisture permeable film 9 can prevent the permeation of water through the closing plate 5, so that the wide-mouth container 1 can be sealed for a long time. It is possible to prevent the contents B from being deteriorated by moisture or being excessively dried over the course of time without increasing the manufacturing cost of the lid body 2. Moreover, various patterns, trademarks, etc. can be provided on the non-moisture permeable film 9. Since it can be printed in advance, the appearance of the lid body 2 can be improved.

In this case, the non-moisture permeable film 9 may be attached to at least a portion of the surface of the closing plate 5 corresponding to the opening hole 4, and the non-moisture permeable film 9 may be a metal foil other than an aluminum foil. Alternatively, a synthetic resin film such as polypropylene may be used, and a non-moisture permeable film 9
In the case of using a metal foil, forming a synthetic resin film on both the front and back surfaces has the advantage that the printability and the adhesion to the closing plate 5 can be improved (in that case, the synthetic resin film is used as the closing plate 5). If the same material is used, the adhesion strength to the closing plate 5 will be further improved).

As shown by the chain double-dashed line in FIG. 2 and FIG. 3, the opening hole 4 is formed concentrically with the lid body 2 and the opening hole 4 is formed.
It is also possible to form a straight line portion on the weakening line 6 of the closing plate body 5 and to form a slide-cutting projection 7 along the straight line portion on the weakening line 6 while closing the same with the above.

FIGS. 5 to 6 show a second embodiment of the present invention, in which the inner peripheral edge of the lid 2 is bent in a U-shape in a lateral cross section, while the V groove 6 in the closing plate 5 is covered with the lid. 2 is formed on the outer surface of the opening hole 4 in the opening 2, the tubular plug portion 5c is engaged with the opening portion 5a of the closing plate body 5 and engages and disengages with the inner peripheral edge of the opening hole 4 of the lid body 2 after opening. Is integrally formed, and further, a plate-shaped slidable projection 7 projecting toward the inside of the wide-mouth container 1 is integrally formed on the inner surface side of the peripheral edge portion 5b of the closing plate body 5.

In addition, in the first and second embodiments, the number of the slide-cutting protrusions 7 is not limited to one, and the slide-cutting protrusions 7 may be provided at a plurality of positions along the V-groove 6. May be formed on the outer surface of the closing plate 5.

Further, in the case of the first embodiment, the unsealing portion in the closing plate body 5
5a does not necessarily have to be configured to be cut off. For example, as shown in FIG.
It is provided at a position opposite to the straight portion 4a of the opening hole 4 so that only the arc-shaped portion of the loop-shaped V groove 6 is torn, or the V groove 6 is formed in a non-loop shape. As a result, the unsealed portion 5a may be attached to the peripheral edge portion 5b of the closing plate body 5 in a bendable state even after unsealing. In this case, the unsealed portion 5a may be attached to the second embodiment. By an appropriate means such as an example, the lid 2 may be detachably attached to the inner peripheral edge after opening.

Further, in providing the gripping piece, as shown by the alternate long and short dash line in FIG. 1, the weakening line such as the V groove 6 is formed with the convex portion 6a protruding outward in the radius of the lid 2 (the weakening line 6). May be formed in a wavy shape in plan view), and the pull ring 7
A gripping piece such as the above may be provided, and in this way, since the pulling force can be concentrated on the weakened line 6 at the beginning of opening, the opening can be performed with a light force.
