Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a lid for a disposable beverage container. More particularly, the present invention relates to a lid for a hot drink container.

[Prior Art] In recent years, due to the diversification of eating habits, it has become popular among young people to buy hamburgers and fried chicken at fast-food restaurants and the like and easily finish their meals.

At this time, most consumers also purchase beverages at the same time. Beverages sold at fast food restaurants are broadly divided into cold beverages (cold drinks) and hot beverages (hot drinks).

In both cases of eating at the store and bringing it home, the drink is filled in a disposable container made of paper or the like, and the container opening is covered and sold. The lid is to prevent airborne dust and the like from falling into the beverage in the container and mixing.
This is to maintain the cleanliness and hygiene of the beverage.

When the drink is a cold drink, ingestion of the drink in the container is generally performed by a straw. For this reason, the lid for a cold drink is provided with a cross-shaped notch or the like for penetrating the straw on the upper surface thereof.
By inserting the straw into the container from the cross-shaped notch, it is possible to take the cold drink in the container without removing the entire lid from the rim of the container.

However, when the beverage is a hot drink, ingestion with a straw is not generally performed because the straw itself does not have heat resistance. Therefore, in order to take the hot drink in the container, the entire lid must be removed from the rim of the container. If the entire lid is removed in this way, the original purpose of using the lid becomes meaningless.

[Problems to be Solved by the Invention] Accordingly, an object of the present invention is a lid to be applied to the rim of a disposable container filled with hot drink, and the lid must be removed from the rim of the container. It is also to provide a lid on which the hot drink in the container can be taken.

[Means for Solving Problems] As a means for solving the above-mentioned problems and also achieving the object of the present invention, the present invention is a groove-shaped lid provided on the rim of a beverage container. A rib having a rib, wherein a knob piece protruding outward in the radial direction is provided at a part of an outer lower end portion of the rib, and the rib is sandwiched to open at a position facing the knob piece. A forming portion is provided, and a fitting groove defined by the rib and the recessed flat surface portion is provided on a part of the rib on the inner side in the radial direction on the inner side in the radial direction of the rib. A lid for a beverage container is provided.

[Operation] As described above, the lid of the present invention is provided with the opening forming portion near the outer periphery of the concave plane portion. A knob piece is provided at a position facing the opening forming portion. A slight length of incision is made from both inner ends of the knob piece toward the outer peripheral side wall of the rib.

Therefore, when the piece is pulled or pulled up, a crack is formed from the cut portion, and the crack reaches the opening forming portion. If the opening forming portion is discontinuously cut or half-cut, the crack further progresses along the discontinuous notch or half-cut line. The crack progresses at the end of the notch line or half-cut line.

Here, the opening forming piece is bent outward in the radial direction, and the remaining portion of the rib attached to the opening forming piece is fitted into the fitting groove defined by the rib and the recessed flat surface portion. Thus, even if the opening forming piece is not shredded, the opening is formed on the recessed flat surface portion of the lid, and the opening forming piece can be retained and engaged in the fitting groove, so that the opening is not shredded. The formed pieces do not interfere with the intake of the beverage.

In this way, the hot drink filled in the container can be taken without removing the entire lid from the rim of the container.

[Example] Hereinafter, an example of the lid of the present invention will be described in more detail with reference to the drawings.

1 is a top view of the lid of the present invention, and FIG. 2 is a top view of FIG.
FIG. 3 is an enlarged cross-sectional view taken along line II-II, FIG. 3 is an enlarged cross-sectional view of the half-cut line, FIG. 4 is a top view of the lid with an opening formed, and FIG. FIG. 5 is an enlarged cross-sectional view taken along the line VV of FIG. 4, and FIG. 6 is an enlarged cross-sectional view of another state in which an opening is formed.

In the preferably integrally formed lid 50 of the present invention shown in FIG. 1, 1 is a rib, 3 is a recessed flat surface defined by the rib, and 5 is a peripheral skirt edge. . Further, 10 indicates an opening forming portion, and 20 indicates a knob piece. Reference numeral 30 denotes a fitting groove defined by the rib 1 and the concave flat surface portion 3.

As shown in FIG. 2, the rib 1 has a groove shape defined by an upper side wall 6, an outer peripheral side wall 7 and an inner peripheral side wall 8. The lower portion of the outer peripheral side wall 7 is slightly curved inward in the radial direction. The lip 42 of the container 40 is fitted in the groove. Since the lower part of the outer peripheral side wall 7 is curved inward in the radial direction, the container rim 42 has the outer peripheral side wall 7 and the inner peripheral side wall 8.
And held stronger by. As a result, the lid is firmly attached to the container.

Similarly, as shown in FIG.
Extends radially outward from the lower end portion 9 of the outer peripheral side wall 7 of the rib to strengthen the outer peripheral edge of the lid.

The opening forming portion 10 is arranged near the outer circumference of the concave plane portion 3.
This is because the opening is arranged close to the ribs so that the beverage in the container can be completely consumed.

The opening forming portion 10 is bordered by two substantially symmetrical discontinuous cut lines 12a and 12b as shown in FIG. Alternatively, as shown in FIG.
A so-called half-cut line 16 can also be used for edging.
The score line completely penetrates the upper and lower surfaces, but the half cut line does not penetrate. The thin portion 18 of the meat has a weak mechanical strength and is torn along this portion. The opening forming portion 10 preferably has a so-called divergent shape that opens outward from the central portion of the lid in the radial direction. It is preferable that the cut lines or the half cut lines of the rib 1 near the inner peripheral side wall do not intersect with each other. This is for facilitating the formation of an opening by the knob piece 20 (described later). In addition, the pair of cut lines extending toward the central portion of the lid are separated from each other without intersecting each other. This is because the opening forming piece (described later) is bent at this portion. In order to facilitate bending, a pair of score lines 12a and 12b have a radially inner end portion 1
It is also possible to dispose the cut line on the thin groove-shaped preliminary folding line connecting 4a and 14b or on the line connecting the end portions.

A knob piece 20 of a predetermined size is provided on a part of the outer peripheral skirt edge 5 so as to project radially outward. The knob piece 20 is provided at a position facing the opening forming portion 10 with the rib 1 sandwiched therebetween. The knob piece 20 is integrated with the outer peripheral side wall 7 of the rib 1 and has notches 22a and 22b provided between the knob piece 20 and the outer peripheral skirt edge 5. The notch communicates with the notches 24a and 24b having a length that does not reach the upper side wall of the rib as it extends upward from the outer peripheral side wall of the rib.

With the lid of the present invention applied to the rim of the container, the knob piece 2
When 0 is pulled outward or caused to rise upward, a crack linearly progresses from the notch 24a and 24b at one end of the knob to the outer peripheral side wall, the upper side wall and the inner peripheral side wall of the rib. Score lines 12a and 1
Reach 2b. By further pulling up the knob piece, the crack progresses along the score lines 12a and 12b.
Crack propagation stops at the radially inner ends 14a and 14b of the symmetrical score lines 12a and 12b.

Here, as shown in FIG. 4 and FIG. 5, the opening forming piece 11 is cut into the cut lines 12a and 12b at the ends 14a.
Bend to the other side along the line 15 connecting
By fitting the cut-out remaining portion 13 of the rib attached to the opening forming piece 11 into the fitting groove 30, the opening forming piece 11 can be retained and engaged in the fitting groove 30. If the width of the groove 30 is larger than the width of the rib 1, the opening forming piece cannot be locked. On the other hand, if it is too small, it becomes difficult to insert it. Therefore, the width of the fitting groove 30 is substantially the same as the width of the rib 1 or slightly smaller.

In FIGS. 1 and 2, when the center point of the lid is indicated by C, the line 15 connecting the end portions 14a and 14b toward the center of the pair of cut lines 12a and 12b has a rib half width smaller than the center point C. When it is only on the side of the knob, as shown in FIG. 4 and FIG. 5, the uncut portion 13 of the rib is fitted into the fitting groove 30 on the opposite side and retained and engaged. On the other hand, when the line 15 'comes to a position that exceeds the center point C by a half width of the rib, as shown in FIG. 6, the uncut portion 19 of the fitting groove 30 is fitted into the rib 1 to form an opening. The piece 11 is retained and engaged. The lid of the present invention can be implemented in any of the above modes.

The depth of the fitting groove 30 is not particularly limited, but is preferably about half the height of the inner peripheral side wall 8 of the rib 1. This makes it possible to deal with both the case where the remaining cutout portion 13 of the rib is fitted into the fitting groove 30 and the case where the remaining cutout portion 19 of the fitting groove is fitted into the rib 1. Which mode to carry out can be determined in consideration of factors such as the application of the container.

The rib 1 and the fitting groove 30 are concentric. However, the fitting groove 30 does not need to be arranged all around the inside of the rib. It is also possible to dispose the opening forming piece 11 only at a portion necessary for locking.

And finally, as shown in FIG. 4, an opening 17 is formed at the lid recessed flat surface portion 3. It is preferable that the opening 17 has a shape in which the central portion of the lid is narrow and the outer peripheral portion is wide. Such a wide mouth opening is very convenient for ingesting the beverage in the container. The openings 17 preferably have a radial length such that they are not completely covered by the upper lip of a human. If the opening has such a length, the opening portion near the central portion of the lid can function as an air vent. Thus, the beverage in the container can be smoothly taken.

The size and material of the lid are not essential to the invention. The size can be changed according to the size of the opening of the container to be covered. As the material, generally, plastics such as styrene can be used. It is extremely preferable to use plastics as the material of the lid because mass production can be easily performed by a blow molding method or the like.

The lid of the present invention is particularly suitable for capping a disposable container for hot drinks, but can of course be used for cold drink containers.

[Advantages of the Invention] As described above, the lid of the present invention is provided with the opening forming portion near the outer periphery of the concave plane portion. A knob piece is provided at a position facing the opening forming portion. A slight length of incision is made from both inner ends of the knob piece toward the outer peripheral side wall of the rib. Therefore, when the knob piece is pulled or pulled up, a crack is formed from the cut portion, and the crack reaches the opening forming portion.

If the opening forming part is subjected to discontinuous notch or half cut processing, the crack further progresses along this discontinuous notch or half cut line, and the progress of crack at the end of the notch line or half cut line Stop.

Here, the opening forming piece is bent outward in the radial direction along the line 15 connecting the ends of the cutout line or the half cut line, and the remaining portion of the rib attached to the opening forming piece is connected to the inner peripheral side of the rib. It is fitted into the fitting groove provided. Thus, the opening is formed on the recessed flat surface portion of the lid without cutting the opening forming piece, and the opening forming piece can be retained and engaged with the fitting groove.

If the configuration is such that the opening forming piece is cut into pieces, the problem of disposing of the cut opening forming pieces becomes a problem. In most cases, it just gets in the way, so it is thrown away directly on the street, floor, ground, etc., like a cigarette crust, and dissipated.
It will spoil the beauty of the city. The lid of the present invention solves this problem, and since the opening forming piece is retained and engaged with the lid until the end, it is thrown into a trash box or the like together with the container for disposal. Further, since the opening forming piece is bent and is retained and engaged, when the beverage in the container is ingested through the opening, the opening forming piece does not hit the nose and can be used extremely comfortably.

As described above, according to the lid of the present invention, the hot drink filled in the container can be taken very smoothly without removing the entire lid from the rim of the container.
Moreover, most of the recessed flat surface portion of the lid remains, so that the original dustproof function of the lid is sufficiently fulfilled.

The lid of the present invention is particularly suitable for ingesting a beverage in a container without using a straw.

Japanese Utility Model Laid-Open No. 60-47251 discloses a lid in which an opening can be formed on the upper surface of the lid. However, this lid does not have a mechanism for locking the opening forming piece after forming the opening. Therefore, in the case of this lid, since the opening forming piece remains on the upper surface of the lid without being locked, when the hot drink in the container is directly tried to drink from the opening, the opening forming piece hits the nose and becomes uncomfortable. To avoid hitting the nose with the nose, the nose must be finger pressed or shredded.

Further, in Japanese Utility Model Laid-Open No. 56-109961, in order to enhance the fitting strength of the lid with respect to the container mouth edge portion when the lid is applied to the container mouth edge portion, an inner peripheral surface is formed on a concave flat surface portion of the lid upper surface. A downward protruding portion continuous from the side wall is formed in a circumferentially interrupted shape.
However, in this lid, the downward projecting portion is interrupted at a portion corresponding to the opening forming portion, and a bulging portion is formed there to assist in draining hot water. Therefore, even if the opening forming piece is bent, the opening forming piece cannot be fitted to the downward protruding portion.

Therefore, Japanese Utility Model Laid-Open No. 60-47251 and Japanese Utility Model Laid-Open No.
The lid of the present invention cannot be conceived by anyone skilled in the art from the lid disclosed in Japanese Patent Publication No. 6-109961.
