Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a so-called pull-open type lid device in a lid device for a mouth part of a wide-mouthed container, in which a gripping piece provided on the outer surface side of the lid device is pulled to open.

[0002]

[Prior art]

 A pull-open type lid device for the mouth of a wide-mouthed container is generally formed by a single metal plate, and a thin weakening line is engraved in a loop shape on the lid device to open the opening portion. Then, a pull ring formed by bending a ring-shaped metal plate is fixed by caulking at a position near the weakening line on the outer surface of the unsealing part, and the pull ring is pulled to open the unsealing part. It is constructed so that it can be opened by cutting off the.

However, when the entire lid device is formed of a metal plate in this way, the inner peripheral edge of the opening hole formed after opening and the outer peripheral edge of the cut open portion are sharply angled, so that the opening is opened. When you put your lips on the hole and drink the contents, or when you put your hand in the opening hole and put the article in and out of the wide-mouth container, you may hurt your lips or hands at the inner edge of the opening hole, or However, there was a problem in that accidents often occurred when the cut open part touched the body and got injured.

Therefore, as a means for solving these safety problems after opening, US Pat. No. 4,674,649, which is a prior art, is fitted to the mouth portion of the wide-mouth container 10 as shown in FIG. A lid 11 made of a metal plate is provided with an opening hole 11a having an appropriate shape, and the opening 11a is formed on the inner peripheral edge of the inner edge of the lid 11, that is, inside the wide-mouthed container 10. The lip portion 11b is formed by bending the lid portion 11b in a reverse L-shape toward the outside, while the closing plate body 12 made of a soft synthetic resin for closing the opening hole 11a in the lid body 11 is closed. In the outer peripheral portion 12a, the lip portion 11b at the inner peripheral edge of the opening hole 11a is integrally molded so as to be wrapped from inside and outside, and further, in the outer peripheral portion 12a of the closing plate body 12, inside the opening hole 11a. Perimeter The portion located at the tip of the lip portion 11b in the above is formed in the thin portion 12b, while the gripping piece 13 is integrally provided on the outer surface of the closing plate body 12, and the gripping piece 13 is pulled upward. Thus, as shown in FIG. 7B, there is disclosed a lid device in which the closing plate body 12 is torn and opened along the thin portion 12b at the tip of the lip portion 11b.

[0005]

[Problems to be solved by the device]

 However, this prior art lid device has a problem that the sealing function of the container and the safety after opening are incomplete. That is, in the lid device in this prior art, the inner peripheral edge of the opening hole 11a in the lid 11 made of a metal plate is bent inward to form the lip portion 11b, while the soft portion integrally formed in the lid 11 is formed. The closing plate body 12 made of synthetic resin is provided with a thin portion 12b at a portion of the lip portion 11b, and is cut along the thin portion 12b to open the opening, in other words, the soft synthetic resin. Since the thin wall portion 12b of the closing plate body 12 is cut and opened by using the lip portion 11b of the metal plate lid 11 as a cutting blade, the container is opened with this lid device. By placing another object on the closing plate body 12 in a sealed state or by pressing the upper surface of the closing plate body 12 by hand, an external force is applied downwardly from the closing plate body 12 to the closing plate body 12. When it works Or, conversely, when an external force is applied to the closing plate body 12 from below to above, as in the case where the inside of the wide-mouthed container is packed at a pressure higher than atmospheric pressure, the closing plate Since the thin portion 12b of the body 82 is easily torn by the lip portion 11b, there is a possibility that the container is not completely sealed.

Further, as described above, the lid body of this prior art uses the thin portion 12b of the closing plate body 12 made of soft synthetic resin as the cutting blade and the lip portion 11b of the lid body 11 made of the metal plate as a cutting blade. Since the lip portion 11b is exposed on the inner peripheral surface of the opening hole 11a in the lid body 11 after the closing plate body 12 is opened, the wide-mouth container is opened after the opening. When putting a hand in and out of the inside of the hand 10, there is a possibility that the hand may be injured by the tip edge of the lip portion 11b, and the safety is not sufficiently secured.

It is an object of the present invention to provide a lid device that improves the sealing function of a container and ensures the safety after opening.

[0008]

[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, with an opening hole having an appropriate shape, and a soft synthetic resin for closing the opening hole. An oil-made closing plate is integrally formed so as to cover substantially the entire outer surface or inner surface of the lid, and the inner side of the opening hole in the lid of the closing plate is radially inward. A weakening line for forming an opening part is formed on the closed plate body at the position located, and a gripping piece for the opening part is further formed on a part of the outer surface of the opening part close to the weakening line. It is configured to be provided.

[0009]

[Operation and effect of the device]

 In this way, if the closing plate is integrally formed so as to cover substantially the entire outer surface or inner surface of the lid, the area where the closing plate comes into close contact with the lid increases, so the strength of attachment of the closing plate to the lid is increased. In addition, when fixing the outer peripheral edge of the lid to the mouth of the wide-mouthed container by means such as wrapping and caulking, the outer peripheral edge of the closing plate is inserted through the lid. Since it becomes possible to adhere to the mouth of the container, even if a large force is applied to the closing plate from the outside of the wide-mouthed container or from the inside of the wide-mouthed container, the closing plate is separated from the lid unexpectedly. In addition to these, the weakening line is located inside the inner peripheral surface of the opening hole so that even if an external force is applied to the closing plate, the weakening line is covered. Sealed because it is not cut at the tip of the inner peripheral edge of the body It is possible to improve the performance.

Since the weakening line for forming the unsealing portion in the closing plate is located inside the inner peripheral surface of the opening hole in the lid, the weakening line is pulled by pulling the gripping piece. After opening the obstruction plate along the point of, the inner peripheral edge of the lid is located outside the inner peripheral surface of the hole formed in the obstruction plate by opening, and the inside of the wide-mouth container is closed. When putting a hand or finger in and out of the lid, the hand or finger does not come into contact with the inner peripheral edge of the lid, in other words, the hand or finger comes into contact with the tip of the inner peripheral edge of the lid. Since it can be prevented by the resin closing plate, it is possible to surely prevent the hand from being injured when the hands and fingers are put in and out of the wide-mouth container after opening.

Therefore, according to the present invention, the sealing function of the wide-mouthed container can be remarkably improved, and the safety after opening can be surely ensured.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 4 show the first embodiment. In these figures, reference numeral 1 is a wide-mouthed container with a bottom formed of an appropriate material such as a thin metal plate or synthetic resin, and reference numeral 2 is The lid | cover apparatus with respect to the mouth part 1a of the above-mentioned wide-mouthed container 1 is each shown.

The lid device 2 includes a lid body 3 made of a metal plate, and an inverted U-shaped mounting portion 3 a to be fitted to the mouth portion 1 a of the wide mouth container 1 is provided on an outer peripheral edge of the lid body 3. The lid 3 is bent and formed, and the mounting portion 3a is wound around the mouth portion 1a of the wide-mouthed container 1 or is swaged so that the lid body 3 is fitted to the mouth portion 1a of the wide-mouthed container 1. ing. An opening hole 4 having a circular shape in plan view is formed in the lid body 3, and a closing plate body 5 made of a soft synthetic resin such as polyethylene for closing the opening hole 5 is attached to the entire outer surface of the lid body 3. The cover plate 5 is integrally formed so as to cover the above-mentioned cover plate, and the block plate 5 is located at a position radially inside the opening hole 4 by an appropriate dimension as an example of a weakening line. The V-shaped groove 6 opening on the inner surface side of the opening 5 is formed in a closed loop shape along the inner peripheral edge of the opening hole 4 to form the opening portion 5a on the closing plate body 5 and the opening portion 5a. A pull ring 7 as an example of a gripping piece is integrally formed on a portion of the portion adjacent to the weakening line 6.

The closing plate 5 is made thicker at the flat portion of the lid 3 where the opening hole 4 is formed, and thin at the attachment 3a portion of the lid 3. By forming the closing plate body 5 integrally with the entire outer surface of the lid body 3, the mounting portion 3a of the lid body 3 can be tightened or crimped around the mouth portion 1a of the wide-mouthed container 3. I try to make it easy.

According to this structure, since the closing plate body 7 is integrally formed with the entire outer surface of the lid body 3, the area where the closing plate body 5 is in close contact with the lid body 3 is increased. The strength of fixation of the closing plate 5 to the cover 3 can be markedly increased, and moreover, when the mounting portion 3a of the lid 3 is fitted to the mouth 1a of the wide-mouthed container 1 by means such as winding and caulking. Since it becomes possible to fix the outer peripheral edge 5b of the closing plate body 5 to the mouth portion 1a of the wide-mouthed container 1, another object may be placed on the closing plate body 6 or the upper surface of the closing plate body 6 may be erroneously placed. Even if it is pressed by hand, or the inside of the wide-mouthed container 1 is packaged at a pressure higher than the atmospheric pressure, or the temperature of the storage location of the wide-mouthed container 1 rises and the internal pressure becomes high, the closing plate body 6 does not peel off from the lid body 3 to improve the sealing performance. It is.

Since the V groove 6 for forming the unsealing portion 5 a in the closing plate body 5 is located on the inner side of the inner peripheral surface of the unsealing hole 4 in the lid body 3, The inner peripheral edge 3b of the lid body 3 is located radially outside the inner peripheral surface of the hole formed in the closing plate body 5 by unsealing, and when a hand or finger is put in or taken out of the wide mouth container 1, The finger and the finger do not come into contact with the inner peripheral edge 3b of the lid body 3. In other words, it is possible to prevent the hand or the finger from coming into contact with the inner peripheral edge 3b of the lid body 3 with the closing plate body 5 made of the soft synthetic resin. Therefore, the safety after opening can be surely improved.

When the entire outer surface of the lid body 3 is covered with the closing plate body 5 as in this embodiment, the lid body 3 made of a metal plate is not exposed to the outside, and the whole lid device 1 may be covered. Since it has an appearance as if it was made of synthetic resin, it has the advantage of improving the appearance. If the outer peripheral surface 6a of the V groove 6 is formed as a conical surface that is inclined toward the outer side of the lid body 3 as it goes inside the wide-mouthed container 1, the contents are obtained by inserting a hand into the wide-mouthed container 1 after opening. When grasping an object, it is possible to prevent the user from strongly rubbing his / her hand against the closing plate body 5, thereby further improving safety.

That is, when the hand is inserted into the wide-mouthed container 1 and the article is taken out, the hand is closed at the time of insertion, and therefore when the hand is inserted into the wide-mouthed container 1, the inner peripheral edge of the closing plate 5 is inserted. Although the hand is not rubbed strongly with, when the item is grasped and the hand is pulled out from the wide-mouthed container 1, the item is inflated, so the back of the hand etc. is rubbed strongly against the inner peripheral edge of the closing plate 5. If the outer peripheral surface 6a of the V groove 6 is formed into a conical surface that widens toward the inside of the wide-mouthed container 1 as in the embodiment, the hand is pulled out from the inside of the wide-mouthed container 1. At this time, since the outer peripheral surface 6a of the V groove 6 serves as a guide function for the outer surface of the hand when the hand is pulled out, it is possible to prevent the back of the hand from being strongly rubbed against the corner portion of the inner peripheral edge of the closing plate body 5, thereby ensuring safety. Can be further improved Of.

FIG. 5 shows the closing plate body 5 integrally formed so as to cover the entire inner surface of the lid body 3. With this construction, the mounting portion 3a of the lid body 3 is simply attached to the wide-mouthed container 1 Even when it is fitted by caulking into the mouth portion 1a of the above, the outer peripheral edge 5b of the closing plate body 5 can be firmly fixed to the mouth portion 1a of the wide-mouthed container 1, and if it is closed, Even if an unexpected situation occurs in which a large force acts on the opening 5a of the plate 5 to cause the closing plate 5 to separate from the flat portion of the lid 3, the outer peripheral edge 5b of the closing plate 5 is closed to the wide-mouthed container 1 Since the state in which it is firmly fixed to the mouth portion 1a is maintained and the closing plate body 7 functions as a packing, there is an advantage that the sealing performance can be further improved.

FIG. 6 shows the pull ring 7 formed in a two-hole type. Needless to say, the shape of the gripping piece is not limited to the pull ring and may be another shape such as a T-shape. It should be noted that if a synthetic resin film is coated on one of the inner and outer surfaces of the lid body 3 on which the closing plate body 5 is integrally formed, the fusion property of the molten synthetic resin to the lid body 3 is improved, so that the lid body 3 is bonded to the lid body 3. The fixing strength of the closing plate body 5 can be improved.

Further, the closing plate may be made of a transparent synthetic resin or the like so that the inside of the wide-mouthed container can be viewed.
