Description

The present invention relates to a packaging body using the hinge cap.

  2. Description of the Related Art Conventionally, a small container is used for a product that contains a large number of grain confectionery, powder, and the like. And in such a small container, in order to make it easy to take out the confectionery by inserting a finger, a relatively wide and large opening having a diameter similar to the diameter of the trunk is arranged on the upper surface. Is closed with a hinge cap so that it can be opened and closed. In addition, since it is a commodity that is displayed and sold in a merchandise shelf that is easy for consumers to take out at retail stores, it is a hinged cap with an unsealed band indicating that it is unopened, and the opening is not removed unless this unsealed band is removed. The one that can not be opened is adopted.

In such commodities, many containers are made of synthetic resin material and hinge caps are also made of synthetic resin material. In the case of the hinge cap, the cap body is formed integrally with the support ring attached over the outer peripheral surface of the opening of the container via the hinge, and the cap body extends in the circumferential direction of the support ring excluding the hinge and both sides thereof. The opening band is also arranged between the support ring and the support ring so as to be integrally formed. An inner ring is provided on the lower surface of the cap body. When the opening is closed with the cap body covering the opening of the container, the inner ring is inside the opening and the base end of the inner ring (the cap body The portion continuous with the lower surface) and the upper end of the opening of the container are in close contact with each other so as to ensure sealing performance.
The inner ring of the cap formed of a synthetic resin material is for enhancing the sealing performance when closing the opening of the container, and is connected by a hinge as shown in Patent Document 1. A cap has also been conventionally provided.
Japanese Patent Laid-Open No. 10-230962

By the way, in recent years, in order to reduce the amount of synthetic resin material in waste, it is required to reduce the amount of synthetic resin material used in various packaging bodies. Attempts have also been made to reduce the amount of synthetic resin material used.
For example, the container is molded from paper and a synthetic resin molded product is arranged only at the opening. Also, with regard to the hinge cap, the thickness of each part is reduced, or the cap height is reduced. Attempts have been made to reduce the depth of the cover to the opening of the container, and the synthetic resin in the package is made by combining a thinly thin hinge cap with a container made mostly of paper. The amount of material used can be greatly reduced.

However, the following problems arise from the point of ease of use as a package.
The cap body that covers the opening in an openable / closable state stands up with respect to the container even when a fingertip is put into the container to take out the contents, or the container is tilted to drop the contents from the opening. It is desirable not to be inclined greatly toward the opening side, but when the cap body is lifted and released, the cap body is integrally connected to the support ring via the hinge and the hinge is restored. The cap naturally moves in the closing direction due to the force and is largely inclined toward the opening, and the cap main body becomes an obstacle when the contents are taken out.
There is a three-point hinge instead of a single hinge as a mechanism that raises the cap body so that it is self-supporting. However, if this three-point hinge is used, the area around the three-point hinge becomes thick due to the structure. There is a disadvantage that leads to an increase in quantity.

Without adopting the above three-point hinge configuration, if the hinge side area of the inner ring has a longer length depending on the bottom surface of the cap body, raise the cap body and release your hand. When the cap body moves to the opening side due to the restoring force of the hinge, the hinge side area of the inner ring comes into contact with the hinge side part at the opening of the container, and the standing state of the cap body can be maintained. It is possible to do.
However, since the entire circumference of the inner ring is thin, the hinge side region is deformed when it comes into contact with the opening, and this deformation causes the cap body to incline toward the opening and cover the opening. When the cap body is closed, there is a problem that the deformed part is strongly locked to the opening, and the deformed part does not get over the upper edge of the opening. There is also a possibility that the whole may not properly enter the opening.
Therefore, in view of the above circumstances, the present invention makes the inner ring and the upper end of the opening contact each other before the cap body falls deeply toward the opening, and no deformation occurs even if the inner ring contacts the upper end of the opening. The cap body is kept in an upright state with a simple configuration in which the inner ring of the raised cap body is brought into contact with the opening of the container, and is accommodated from the opened opening. The object is to make it possible to easily take out an object and to appropriately perform an operation of closing the cap body.

(Invention of Claim 1 )
The present invention has been made in consideration of the above problems, and is a paper container in which a synthetic resin mouth ring is provided on the upper surface to form an opening, and a synthetic resin hinge covered on the opening. A support body, wherein the hinge cap is attached over the outer peripheral surface of the opening of the container, and the upper end of the ring is positioned lower than the upper end of the opening; and the support The cap body is connected to the ring via a hinge so as to open and close the opening of the container. An inner ring is provided on the lower surface of the cap body to enter the inside of the opening when the opening is closed by the cap body. The inner ring so that the length of the inner ring depends for a while from the non-hinge side region opposite to the hinge side in the radial direction of the inner ring to the hinge side region on the hinge side. The lower end edge of the tongue is inclined, and the hinge-side region is provided with a thick wall portion that comes into contact with the upper edge of the opening. It will be solved.

(Invention of Claim 2 )
And in the said invention, it is good that the hanging length dimension of the said hinge side area | region is a length dimension in which an inner ring is located above the opening part of a container at the time of standing of the said cap main body which open | releases an opening part. .
(Invention of Claim 3 )
Moreover, in the said invention, it is good that the part which the upper edge of the opening part contact | abuts in the thick part of the said hinge side area | region is provided in the thickness which maintains the standing state of a cap main body.
(Invention of Claim 4 )
Moreover, in the said invention, it is good that the width dimension in the inner ring circumferential direction of the said thick part is made larger than the width dimension of the said hinge.

(Effect of the invention of claim 1 )
According to the invention of claim 1 , since the thick portion is provided in the hinge side region of the inner ring, when the hinge cap is attached to the container and the cap body is raised, the inner ring of the cap body is tilted in the closing direction. Even if the hinge side region contacts the upper edge of the opening, the hinge side region does not deform and it can get over the opening, and the hinge side region first enters the opening properly and the entire inner ring Smoothly enters the opening. The cap body can be tilted easily and easily.
And the quantity of a synthetic resin material decreases as the whole package, and it can contribute greatly to reduction of the amount of synthetic resins in a package.

(Effect of the invention of claim 2 )
According to the invention of claim 2 , the hinge side region of the inner ring comes into contact with the upper edge of the opening, and the cap body is maintained in an upright state with a simple configuration, so that the package can be easily taken out.

(Effect of the invention of claim 3 )
According to the third aspect of the present invention, the hinge-side region of the inner ring comes into contact with the upper edge of the opening so that the angle at which the cap body stands can be increased, and the hinge can be accommodated with a simple configuration. A package that allows easy removal of the product is obtained.

(Effect of the invention of claim 4 )
According to the invention of claim 4 , the rigidity of the hinge side region can be secured widely, and even if the rotation operation is repeated in a direction in which the cap main body is largely moved backward, the deformation of the hinge is caused by the hinge side of the inner ring. The region is not accompanied by deformation, and accumulation of deformation does not occur in the hinge side region.

Next, the present invention will be described in detail based on the embodiment shown in FIGS.
In the figure, reference numeral 1 denotes a synthetic resin hinge cap. The container that is closed using the hinge cap 1 is of a size that can be handled on a palm, for example, and has an opening having a diameter that is substantially the same as the diameter of the container body. It has a cup-like shape on the top surface.
(container)
For example, FIG. 1 and FIG. 2 show an example in which a packaging body A capable of accommodating small articles is formed inside a container 2 by placing the hinge cap 1 on the container 2, and the container 2 is a paper container. The container body 3 is composed of a main body 3 and a mouth ring 4, and the container body 3 obtains a cylindrical body portion 5 by rounding and laminating and stacking the end portions of a paperboard having a laminated structure mainly composed of paper, The bottom portion 6 of the container 2 is disposed on the lower end side of the body portion 5 with a bottom board having a laminated structure mainly composed of paper in the same manner as the body board, with its periphery folded downward. It is formed by folding the lower end side inward and sandwiching the periphery of the bottom paperboard and integrally heat-sealing.
As shown in FIG. 8, the mouth ring 4 has a welded portion 7 corresponding to the inner peripheral surface of the opening of the container body 3 as a lower stage, and is thick so as to slightly protrude outwardly from the welded portion 7. It is a synthetic resin member formed with the mouth portion 9 continuous through the engaging portion 8 made of meat as the upper stage. The mouth ring 4 is disposed in the upper opening of the container body 3, and the welded portion 7 is The container body 3 is ultrasonically welded to the inner peripheral surface of the opening. In this way, the mouth ring 4 is ultrasonically welded to the container body 3, and the mouth ring 4 constitutes the opening 2 a on the upper surface of the container 2.

(Hinge cap)
The hinge cap 1 is assembled to the mouth ring 4 of the container. As will be described later, the hinge cap 1 is fixed to the container 2 by being locked to the engaging portion 8 of the mouth ring 4. Therefore, the hinge cap 1 includes a configuration and a configuration for covering the mouth portion 9 of the mouth ring 4 and sealing the container.
The basic structure of the hinge cap 1 will be described first. As shown in FIGS. 3 to 5, the hinge cap 1 is connected via a support ring 10 and a hinge 11 provided at a part of the upper end of the support ring 10. And a cap body 12 positioned on the upper portion of the support ring 10. In addition, the hinge cap 1 is also provided with an opening band 13 so that it can be visually confirmed from the appearance whether it is an unopened package in combination with the container 2.
The hinge cap 1 is formed of a synthetic resin material, and the support ring 10, the cap body 12, and the opening band 13 constituting the hinge cap 1 are in an integrated state at the time of molding, as described above. The cap body 12 connected to the support ring 10 via the hinge 11 is positioned at the upper portion of the support ring 10 and extends in the circumferential direction of the hinge cap 1 except for the range including the hinge 11 and both sides of the hinge 11. It is the range which covers, and is shape | molded in the state in which the said opening band 13 was located between the support ring 10 and the cap main body 12. FIG.

The support ring 10 and the cap body 12 at the time of molding are connected to each other through a thin part that is broken by the cause of the cap body 12 in addition to the hinge 11, and the thin part is, for example, from both sides of the hinge 11. It is provided at a boundary portion between the support ring 10 and the cap body 12 in a range up to a portion where the opening band 13 is located.
Further, even in the opening band 13, the region extending over the majority of the support ring 10 in the circumferential direction around the portion of the support ring 10 opposite to the hinge 11 is provided in a range that is shaped like a paragraph. (See FIG. 7), the boundary portion between the upper edge and the lower edge of the unsealing band 13 in the portion made into a paragraph is connected as a thin part that is easy to break, and the height of the upper edge of the unsealing band 13; The height of the upper end 10a excluding the hinge 11 portion and the paragraphed portion of the support ring 10 is aligned, and the cap main body 12 and the opening band 13 are located at the same height as the boundary portion between the cap main body 12 and the support ring 10. The cap body 12 and the unsealing band 13 are connected to each other with a thin portion that can be broken.

In particular, the opening band 13 serves to connect the support ring 10 and the cap body 12 with the opening band 13 therebetween, and the opening band 13 must be raised from one end and cut along the circumferential direction of the hinge cap. The cap body 12 cannot be raised.
Then, by causing the opening band 13 to be removed while holding the knob portion 13a provided integrally on the start end side, the connection relationship between the support ring 10 and the cap body 12 at the portion opposite to the hinge 11 side. The cap body 12 can be lifted by pulling up the cap body 12 from the side opposite to the hinge 11 of the cap body 12 and breaking the thin portion between the cap ring 12 and the support ring 10. If the thin-walled portion is broken, the cap body 12 can be rotated through the hinge 11 in a range from the position on the upper side of the support ring 10 until it can tilt backward.

(Role of opening band)
If the opening band 13 is removed from the package A in the form in which the hinge cap 1 is combined with the container 2, the cap body 12 is raised and a fingertip or the like is put into the container through the mouth ring 4. Since the opening band 13 does not exist in the state in which the cap body 12 is closed, it can be easily determined visually from the appearance of the package A.
On the other hand, if there is an opening band 13, the cap body 12 and the support ring 10 are connected via the opening band 13, so that the unopened package A may be handled inadvertently and dropped. Even if there is, the cap body 12 does not open, and tampering that causes the cap body 12 can be suppressed.

(Locking to engagement part of mouth ring)
In order to fix the hinge cap 1 to the container 2, there is an engaging portion 14 over the inner periphery of the support ring 10 of the hinge cap 1, and the molded hinge cap 1 is attached to the container 2 filled with the contents. The support ring 10 is positioned over the outer peripheral surface of the mouth ring 4 by being put on the mouth ring 4 from above and pushed in, and by engaging the engaging portion 8 of the mouth ring 4 with the engaging portion 14. I have to.
In this way, the support ring 10 is attached to the outer peripheral surface of the mouth ring 4, and the cap body 12 at the top of the support ring 10 covers the mouth ring 4 that is the opening of the container 2. .
When the unopened hinge cap 1 is put on the opening (mouth ring 4) from above the container 2, the cap body 12 covers the mouth ring 4 and seals the inside of the container as described above (FIG. 8). . Further, if the opening band 13 is removed and the cap body 12 is raised to break the thin portion connected to the support ring 10, the cap body 12 rotates while being supported by the support ring 10 via the hinge 11. The cap ring 12 is opened by applying the cap body 12 to the mouth ring 4 or by causing the cap body 12 to wind from the portion opposite to the hinge 11. It becomes the package which enabled opening and closing of the opening part.

(Upper ridge of support ring)
On the inner peripheral side of the support ring 10 along the upper end 10a excluding the hinge 11 portion and the paragraphed portion of the support ring 10, a protrusion 10b whose cross-sectional shape is convex toward the ring center direction is provided. It is provided integrally. When the support ring 10 is properly attached to the mouth ring 4, the protrusion 10 b does not engage with the mouth ring 4 like the engagement portion 14, but the hinge 11 of the support ring 10. The protrusion 10b is provided so as to be engaged with the engaging portion 8 of the mouth ring 4 when a pressure from above is applied so that the side is displaced downward alone. 10 is prevented from coming off unnecessarily, and a contact between the inner ring and the mouth portion of the cap body, which will be described later, is ensured.
The ridge 10b is disposed on the upper end 10a on both sides of the hinge 11, but may be disposed only on the upper end 10a on one side. In any case, the ridge 10b is provided with an opening band from the hinge side. It should be provided up to the partial side (opening end side of band, end side of opening end).

(Close to cap body of mouth)
In order to cover the mouth 9 of the mouth ring 4 with the cap main body 12 and seal the container, the following is configured.
As shown in FIG. 8, the height position of the upper end 10 a of the support ring 10 is provided to be lower than the height position of the upper end 9 a of the mouth portion 9 of the mouth ring 4, as viewed from above. In the positional relationship in a plane, the mouth portion 9 of the mouth ring 4 is located inside the support ring 10, and the upper end 9 a of the mouth portion 9 corresponds to a portion formed along the periphery on the back surface of the cap body 12. I am doing so.
That is, if the hinge cap 1 is put on the container 2 so as to engage the engaging portion 8 and the engaging portion 14, the support ring 10 is attached and fixed over the outer peripheral surface of the mouth ring 4, The upper end 9 a of the mouth portion 9 protrudes from the support ring 10 on the inner peripheral side and above the support ring 10, and the upper end 9 a of the protruded mouth portion 9 is in close contact with the periphery of the lower surface of the cap body 12.

(Cap body)
As shown in FIGS. 4, 5, and 8, an inner ring 15 that enters the inside of the mouth ring 4 when the mouth ring 4 is covered is formed on the lower surface of the cap body 12 in the height direction of the hinge cap 1. It is provided so as to hang downward, and between the base end 16 which is the lower surface side of the cap body 12 of the inner ring 15 and the outer peripheral wall 17 of the cap body 12 bent toward the support ring 10 side. A fitting groove 18 into which the upper end 9a of the mouth part 9 of the mouth ring 4 is fitted is formed, and the cap body 12 is put on the mouth ring 4, and the upper end of the mouth part 9 is fitted into the fitting groove 18 By fitting 9a, the upper end 9a of the opening 9 comes into close contact with the cap body 12 and seals the container 2.

(Inner ring)
As shown in FIG. 8, the portion of the inner ring 15 that hangs down from the base end 16 is formed in a substantially tongue-like shape in the longitudinal section, and in the longitudinal section of the tongue piece 19, the tongue piece 19 The inner peripheral surface 19 a is aligned with the position of the inner peripheral surface of the base end 16, and the outer peripheral surface 19 b is thinned so as to be biased toward the inner peripheral side with respect to the outer peripheral surface position of the base end 16.
Further, the lower end edge of the tongue piece 19, that is, the lower end edge of the inner ring 15 is inclined from the anti-hinge side region 20, which is opposite to the hinge side in the inner ring radial direction, to the hinge side region 21 on the hinge side. . The slope of the lower edge is formed by temporarily increasing the length of the inner ring 15 including the tongue piece 19 so that the length of the droop becomes maximum at the hinge-side region 21 (see FIG. 5).
Thus, since the inner ring 15 has a smaller length of the anti-hinge side region 20 than the length of the hinge side region 21, the cap body 12 is closed after opening the package. The inconvenience that the lower end edge of the anti-hinge side region 20 hits the upper end 9a of the mouth portion 9 is extremely reduced, and the closing operation of the cap body 12 is simplified.

(Standing and tilting the cap body)
On the other hand, the sag length dimension of the hinge-side region 21 of the inner ring 15 is such that when the cap body 12 is erected at an angle at which the cap body 12 is substantially raised in the form of a package, the hinge-side region 21 9 is a dimension that is located above the upper end 9a of the plate 9. Further, the hinge-side region 21 of the inner ring 15 is integrally provided with a thick-walled portion 22 on the outer peripheral surface side of the tongue piece portion 19, and when the cap body 12 is raised at an almost standing angle, the thickness is increased. The meat portion 22 is provided so as to be close to the upper end 9 a of the mouth portion 9.
As described above, the length of the hinge-side region 21 depends on the length of the inner ring 15 above the upper end 9a of the mouth portion 9 when the cap is upright, and the thick-walled portion 22 is formed in the hinge-side region 21. Since the inner ring 15 and the upper end 9a are close together, the following effects are obtained.
First, when the cap body 12 is lifted up by hand operation and is turned up so that it is almost upright or tilted outward, the cap body 12 is moved toward the mouth ring 4 by the restoring force of the hinge 11. The thick wall portion 22 comes into contact with the upper end 9a of the mouth portion 9 on the side of the hinge 11 immediately after passing the standing position slightly (Fig. 9). The cap body 12 is maintained in the standing state without falling down. Since the cap body 12 is prevented from falling down, the cap body 12 does not get in the way when taking out the contents of the container 2.

Further, since the hinge-side region 21 is provided with the thick portion 22, the strength of the inner ring 15 at that portion is increased and reinforced, and the mouth portion 9 comes into contact with the restoring force of the hinge 11. The inner ring 15 is not deformed to the extent.
Furthermore, in order to close the container 2, the cap body 12 in an upright state is manually pushed down, and in this case, the upper end 9a of the mouth portion 9 presses the inner ring 15 of the hinge side region 21 to some extent. However, since the strength of the hinge-side region 21 is increased by providing the thick portion 22 as described above, the cap main body 12 that contacts the thick portion 22 with the upper end 9a of the mouth portion 9 is brought down. At the time of insertion, the hinge-side region 21 does not bend or is merely deformed to a slight extent, and the hinge-side region 21 is used to rotate the cap body 12 in the closing direction. At the same time, the upper end 9a of the mouth portion 9 is smoothly slipped over to enter the mouth portion 9, and the entire inner ring properly enters the mouth portion 9 as the hinge side region 21 is moved. -Ring can properly closing the cap body 12 without things like biting the. Therefore, the hinge side area 21 is not damaged, and damage due to the accumulation of repeated deformations accompanying the opening / closing operation does not occur.

(Reinforcement of the hinge side area against backwards)
In addition, when a tilting operation is performed in which the cap body 12 is tilted back so as to be warped, the stress that deforms the hinge side region 21 is transmitted to the hinge side region 21 as the hinge 11 is deformed. The thickness of the thick portion 22 in the circumferential direction of the inner ring is larger than the width of the hinge 11 as shown in FIG. Even when the cap body is rotated repeatedly, the hinge-side region 21 does not accumulate deformation.
Therefore, the function of maintaining the standing when the cap main body 12 is raised is not impaired, and the proper upper end of the proper mouth portion of the hinge side region when the cap main body 12 is tilted down and the proper fitting into the mouth portion are not affected. Intrusion is not impaired.
