Description

Description: TECHNICAL FIELD The present invention relates to a container lid having a so-called prize characteristic, and more particularly to a container lid having a prize characteristic in which a shell is broken along a line of weakness upon opening. About.

(Prior art)

As is well known, recently, a simple opening type container lid in which a shell is broken along a pair of weakening lines upon opening is widely used. The shell of such a container lid includes a top wall, a tubular skirt wall hanging from the periphery of the top wall, and a gripping piece projecting from a lower end of the skirt wall.
At least the top wall and the skirt wall are formed from sheet metal. The gripping piece can also be formed of a sheet metal integrally with the top wall and the skirt wall. Alternatively, a part or the whole of the gripping piece can be molded from synthetic resin and connected to a required portion. The pair of weakening lines extend up the skirt wall from near both sides of the base end of the gripping piece, and then extend in a required form at the boundary region between the skirt wall and the top wall or the top wall. A liner made of synthetic resin is provided on the inner surface of the top wall of the shell. Such a liner has an annular shape extending annularly around the inner peripheral portion of the top wall, or a disk shape extending not only at the peripheral edge of the inner surface of the top wall but also at the central portion.

On the other hand, JP-A-54-97188 and JP-A-56-113552
The publication discloses that a part of the liner disposed on the inner surface of the top wall of the shell can be peeled off and removed from the shell, and the upper surface of the peeling and removing portion (that is, the inner surface of the top wall of the shell) It is disclosed that the prize print is selectively applied to the surface (the surface facing the side) so as to impart a prize characteristic to the container lid.

[Problems of the prior art]

Thus, in a conventional container lid having a prize characteristic,
Whether or not the specified removal printing has been applied to the peeling removal part of the liner,
In other words, in order to know whether or not a prize has been won, remove the container lid from the mouth and neck of the container, open the mouth and neck, and then grasp the knob and the like formed on the liner and pull the liner. It was necessary to perform an operation of at least peeling or peeling and removing the peeling and removing portion from the inner surface of the top wall of the shell. Such an operation is relatively troublesome, and does not cause any particular problem when the prize falls. However, when the prize does not correspond to the prize, the troublesome operation remains as discomfort, and the prize characteristic is not sufficient for sales promotion of the product. It was not always useful.

[Solution of the Invention]

The present invention has been made in view of the above facts, and its main technical problem is to remove the container lid from the mouth and neck of the container when applying the prize characteristic to the simple opening type container lid of the above-described embodiment. As long as the operation of opening the mouth and neck is performed, the peeling portion (additional portion) of the liner is peeled off from the inner surface of the top wall of the shell without adding an operation such as pulling a part of the liner. The upper surface of the peeling portion (addition portion) or the inner surface of the top wall of the shell can be visually recognized as to whether or not the area covered with the peeling portion (addition portion) of the liner has been subjected to predetermined printing. Thus, it is an object of the present invention to solve the above-mentioned problems existing in the conventional container lid having a prize characteristic.

[Solution of the Invention]

Means for solving the above technical problems of the present invention,
(A) The main portion of the liner disposed on the inner surface of the top wall of the shell is formed into an annular shape in which the peripheral portion of the inner surface of the top wall extends in an annular shape, and an additional portion having a specific configuration is added to the annular main portion of the liner. That is, an additional portion projecting radially inward from the annular main portion at an angular position corresponding to the gripping piece and located between the pair of weakening lines is provided, and (b) at least a part of the annular main portion of the liner is a shell. Glued to the inner surface of the top wall of
The additional part of the liner is made non-adhesive or weakly adhered to the inner surface of the top wall of the shell, and (c) prize printing is selected on the upper surface of the additional part of the liner or the area covered by the additional part of the liner on the inner surface of the top wall of the shell. It is to apply it.

That is, according to the present invention, a top wall, a tubular skirt wall hanging down from a periphery of the top wall, and a gripping piece projecting from a lower end of the skirt wall are included, and at least the top wall and the skirt wall are made of a thin metal plate. The skirt wall and the top wall extend upward from the vicinity of both sides of the base end of the gripping piece, and then a pair of a boundary region between the skirt wall and the top wall or the pair extending along the top wall. A container lid comprising: a shell in which a weakening line is formed; and a synthetic resin annular liner having an annular main portion extending annularly around an inner peripheral edge of the top wall of the shell. An additional portion protruding radially inward from the annular main portion at an angular position corresponding to and located between the pair of weakening lines, wherein at least a portion of the annular main portion of the liner includes the shell. Contact the inside of the top wall The additional portion of the liner is non-adhered or weakly adhered to the inner surface of the top wall of the shell, and the upper surface of the additional portion of the liner or the inner surface of the upper wall of the shell is A container lid is provided, wherein a prize print is selectively applied to an area covered by the additional portion.

The annular main portion of the liner extends across the pair of weakening lines, and in an area outside the pair of weakening lines, the annular main portion of the liner is provided on an inner surface of the top wall of the shell. It is preferable that non-adhesion or weak adhesion is applied to the substrate.
Preferably, the additional portion of the liner is connected to the annular main portion through a thin portion that can be broken by the container.

[Function of the invention]

In the container lid of the present invention, in order to break the pair of weakening lines by gripping and pulling the gripping piece of the shell to open the mouth and neck of the container, such an action causes the top wall of the shell, particularly the additional portion of the liner, to break. Due to the fact that the located portion is bent upward, the additional portion of the liner is necessarily peeled off from the inner surface of the top wall, and a considerable gap is created between them. Therefore, it is possible to visually recognize whether or not the predetermined printing is performed on the upper surface of the additional portion of the liner without performing a special operation.

If the additional part of the liner is connected to the main part via the thin connecting part, it is possible to easily remove the additional part without requiring special equipment by breaking the thin connecting part. it can.

(Preferred embodiment of the invention)

Hereinafter, with reference to the accompanying drawings, preferred examples of a container lid configured according to the present invention will be described in detail.

Referring to FIGS. 1 and 2, the container lid, generally designated by the numeral 2, is made from a suitable sheet metal, such as aluminum, aluminum-based alloy, tinplate, or chromed netting, which is known per se. It has a shell 4 formed by the method. The shell 4 has a circular top wall 6, a cylindrical skirt wall 8 hanging from the periphery of the top wall 6, and further protrudes somewhat downward from the lower end of the skirt wall 8,
Then, a gripping piece 10 protruding outward in the radial direction is provided. The distal end of the gripping piece 10 is preferably formed in a ring shape so as to be convenient for putting a finger. If desired, the entire gripping piece 10 or the ring-shaped tip can be formed separately from an appropriate synthetic resin and connected to a required portion of the shell 4. In the specific example shown, the gripping piece
A substantially triangular cutout 12 is formed at the lower end of the skirt wall 8 corresponding to both side edges of the base end 10. Then, a pair of weakening lines 14 extending following the pair of notches 12
Are formed. As can be understood by referring to FIGS. 1 and 3, a pair of weakening lines 14 in the illustrated embodiment extend upwardly through the skirt wall 8 substantially parallel to each other from the upper end of the notch 12, and Along the border area between the skirt wall 8 and the top wall 6, it extends somewhat inwardly (and thus within the top wall 6) in opposite directions and in an arc, and further downwards to the axially intermediate portion of the skirt wall 8. ing. Such a weakening line 12 can be formed by making a notch of a required depth from the outer surface or the inner surface of the sheet metal forming the shell 4 to reduce the sheet thickness.

Referring to FIG. 4 together with FIG. 1 to FIG. 3, the inner surface of the top wall 6 of the shell 4 is formed from a suitable synthetic resin material such as polyethylene or polyvinyl chloride by an embossing method or the like. An annular liner 16 that can be formed by an appropriate method is provided. It is important that the annular liner 16 has an additional portion 20 in addition to the annular main portion 18. The annular main portion 18 extends annularly around the inner peripheral edge of the top wall 6 of the shell 4. As shown clearly in FIG. 2, the annular main portion 18 has two annular seal ridges, an outer seal ridge 22 and an inner seal ridge 24. As can be understood by referring to FIG. 4, the annular main portion 18 extends across the pair of weakening lines 14, and not only the inner regions of the pair of weakening lines 14 but also the pair of weakening lines 14. It is also present in the area outside the weakening line 14. The additional portion 20 of the liner 16 has a substantially circular shape, and is connected to the annular main portion 18 via a connecting portion 26. If desired, an elliptical or polygonal additional portion can be formed instead of the substantially circular additional portion 20. At an angular position corresponding to the gripping piece 10 on the shell 4, the additional portion 20 projects radially inward from the annular main portion 18 and is located between the pair of weakening lines 14. The connecting part 26 connecting the annular main part 18 and the additional part 20 includes a thin part 28 whose wall thickness is sufficiently reduced and which can be broken by a relatively small force.

Continuing with FIG. 4, at least a portion of the annular main portion 18 of the liner 16 is adhered to the inner surface of the top wall 6 of the shell 4 and the additional portion 20 of the liner 16 is entirely formed. It is important that the inner surface of the top wall 6 of the shell 4 be non-adhered or weakly adhered (a state in which the adhesive strength is too small to be easily peeled off). In the illustrated embodiment, the liner 16 is non-adhered or weakly adhered to the inner surface of the top wall 6 of the shell 4 in the hatched area A in FIG. In the region B, the inner surface of the top wall 6 of the shell 4 is adhered.
More specifically, the annular main portion 18 of the liner 16 is adhered to the inner surface of the top wall 6 of the shell 4 at an annular inner peripheral portion located inside the pair of weakening lines 14, and otherwise the shell Non-adhesive or weakly-adhered to the inner surface of the top wall 4 of FIG. Therefore, in the region outside the pair of weakening lines 14, the annular main portion 18 of the liner 16 is non-adhered or weakly adhered to the inner surface of the top wall 6 of the shell 4. The additional portion 20 and the connecting portion 26 of the liner 16 are bonded or weakly bonded to the inner surface of the top wall 6 of the shell 4 over the entirety thereof.

The liner 16 is connected to the shell 4 in the hatched area A.
In order to make the liner 16 adhere to the inner surface of the top wall 6 of the shell 4 in the above-mentioned region B, which is cross-hatched, by making the inner surface of the top wall 6 non-adhered or weakly adhered, for example,
The method described in detail in -32108 can advantageously be employed.

Continuing with FIG. 4, the upper surface of the additional portion 20 of the liner 16 (that is, the surface that is brought into contact with or close to the inner surface of the top wall 6 of the shell 4) has, for example, the phrase “this” or the like. Good prize print 30 is provided. Such a prize print 30
Is applied to the inner surface of the top wall 6 of the shell 4 once, and the additional portion 20 of the liner 16 weakly adhered to the inner surface of the top wall 6 is attached to the top wall 6.
It is convenient to allow the prize print 30 applied to the inner surface of the top wall 6 of the shell 4 to be transferred to the additional portion 20 of the liner 16 when peeled from the inner surface of the shell 4. The transfer of the prize print 30 is performed, for example, in U.S. Patent Nos. 3,257,021, 3,361,2.
No. 81, 3,581,690, 3,693,781 and the printing and transfer method disclosed in the drawings. If desired, the prize print 30 applied to the inner surface of the top wall 6 is left on the inner surface of the top wall 6 without being transferred to the additional portion 20 of the liner 16, in other words, the inner surface of the top wall 6. The prize printing can also be applied to the area covered by the additional portion 20 of the liner 16 in FIG.

The container lid 2 as described above, as shown in FIG.
The lower end of the skirt wall 8 is deformed inward in the radial direction so as to be fitted on the neck and neck 34 of the container 32 to be sealed.
The container 32 is attached to the mouth and neck 34 by engaging with an engaging portion 36 formed on the outer peripheral surface of the container 32. Thus container 32
When the container lid 2 is attached to the mouth and neck portion 34 of the container 32, the top wall 6 of the shell 4 closes the mouth and neck portion 34 of the container 32, and the annular main portion 18 of the liner 16 is pressed by the mouth and neck portion 34 of the container 32.
The mouth and neck 34 are sealed.

To open the mouth and neck portion 34 of the container 32, the holding piece of the shell 4 is used.
Pull 10 forward and then pull it up. Then, the pair of weakening lines 14 of the shell 4 starts to be broken and progresses gradually. When the gripping piece 10 of the shell 4 is pulled further backward from above, as shown in FIG. 6, the breakage of the pair of weakening lines 14 progresses to near the end thereof, and a considerable area of the skirt wall 8 is radially outward. To container 32
Of the skirt wall 8 with respect to the mouth and neck 34 of the container 32 is released over a considerable area, and the entire container lid 2 is disengaged from the mouth and neck 34 of the container 32, and the mouth and neck 34 is released. In the above-described opening operation, the liner 16 behaves as follows. Referring to FIGS. 4 and 6, the annular main portion 18 of the liner 16 will be described.
Are bonded to the inner surface of the top wall 6 of the shell 4 in the region inside the pair of weakening lines 14, but are not bonded or weakly bonded in the region outside the pair of weakening lines 14. Therefore, when the inner region of the pair of weakening lines 14 in the top wall 6 of the shell 4 is displaced upward, the outer peripheral portion of the annular main portion 18 of the liner 16 (the outer region of the pair of weakening lines 14) becomes Along with the inner peripheral portion of the annular main portion 18 of the top wall 6 (the area inside the pair of weakening lines 14), it is displaced upward together with the inner area of the pair of weakening lines 14 on the top wall 6 of the shell 4. The outer peripheral portion of the annular main portion 18 of the liner 16 is separated from the inner surface of the top wall 6 of the shell 4 and is displaced upward, so that the forcing is promoted radially outward of the skirt wall 8, and the mouth and neck portion 34 of the container 32. Of the skirt wall 8 is promoted. On the other hand, as for the additional portion 20 of the liner 16, since the entire additional portion 20 is in a non-adhered or weakly adhered state with respect to the inner surface of the top wall 6 of the shell 4, as shown in FIG. When the inner regions of the pair of weakening lines 14 are curved in a roll shape in accordance with the upward displacement, the additional portion 20 of the liner 16 is not curved along with the curvature of the top wall 6, and is not bent. Is separated from the inner surface of and separated therefrom. As can be clearly understood by referring to FIG.
In the state in which is removed from the mouth and neck portion 34 of the container 32, the additional portion 20 of the liner 16 is sufficiently separated from the inner surface of the top wall 6 of the shell 4. Therefore, the consumer is covered by the additional portion 20 on the upper surface of the additional portion 20 of the liner 16 (or the inner surface of the top wall 6 of the shell 4) without having to perform further special operations on the additional portion 20 of the liner 16. It is possible to easily visually recognize whether or not the prize print 30 has been applied to the (area). If a prize system is adopted in which only the additional section 20 on which the prize print 30 is applied is separated and sent to the seller, the additional section 20 of the liner 16 is grasped and pulled to connect the connecting section 26.
The thin portion 28 in the above can be broken, and thus only the additional portion 20 can be separated.

(Effect)

In the container lid constructed according to the present invention, the additional portion of the liner is peeled off from the inner surface of the top wall of the shell as long as the container lid is detached from the mouth and neck of the container and the operation of opening the mouth and neck is performed. It is sufficiently separated so that it is sufficiently easy to see whether or not the prize print has been applied to the area covered by the liner addition on the upper surface of the liner addition or on the inner surface of the top wall of the shell. .
