Description

  In the present invention, various liquid drinks such as juice and cola, and foods and drinks such as popcorn are sold in small portions at fast food stores, and used for carrying or sticky semi-liquid foods such as jam, ice cream and yogurt. The present invention relates to a container lid that seals a container opening by hinge lock engagement to a cup-shaped container used at the time of sale and can open the container opening by a single operation.

Background technology

Conventionally, fast food stores sell various liquid drinks such as juice and cola, and food and drinks such as popcorn in fast food stores, and use paper or synthetic resin cup containers for carrying, and cover the container openings. In general, synthetic resin lids are widely used. (Hereafter referred to as drink lid lid use)
In addition, paper or synthetic resin containers are often used for cup-shaped containers used for selling sticky semi-liquid foods such as ice cream, and aluminum is used to seal the container opening of this type of container. The foil is sealed as a lid. (Hereinafter referred to as using a sealing lid)
As a lid of a paper or synthetic resin container containing a semi-liquid food such as jam or ice cream, the above-mentioned seal lid and a separately manufactured paper lid are used in combination. (Referred to as a combination lid)
Furthermore, as a simple lid for paper cups, the top curl portion of the paper cup is locked by the opposing locking portions by folding the bent portions on both sides of the simple lid downward so that the top curl portion of the paper cup is locked and held. There is a simple lid for paper cups.

JP-A-6-100029 Japanese Utility Model Publication No. 61-12726 JP 2002-154560 A

  When a seal lid is used as the lid material, the adhesive strength can be increased, but depending on the content of food and drink contained in the cup-shaped container using the seal lid, it may not be possible to eat all at once, There is a problem that it cannot be used repeatedly. (See Patent Document 1 Japanese Patent Laid-Open No. 6-100029)

In a cup-shaped container using a drink lid lid, put granular processed foods such as liquid drinks and popcorn, seal the container opening, and lock the piece on the lid or flange part of the container. Can also be used.
The drink lid lid can be used repeatedly even if it is opened once, but sometimes when using this lid, there is a problem that when the lid is dropped on the floor with the container or inverted, the lid will come off and the beverage or granular processed food will spill . (See Japanese Patent Application Laid-Open No. 61-12726)

  In the case of a cup-shaped container using a combination lid, the combined sealing force between the container and a sealing lid such as a paper lid is low, and there is also a problem that the container comes off if only the sealing lid is provided.

As in the invention described in Japanese Patent Application Laid-Open No. 2002-154560, the paper cup opening is sealed, and the bent portions on both sides of the lid are bent downward so as to lock and hold the top curl portion. There is also a lid that locks the paper cup top curl portion by the opposite locking portions.
In the case of a lid used for this type of container, depending on the size of the contents put in the container, when the contents are taken out, the opposite locking of the lid that locks the top curl portion of the paper cup When it is necessary to remove the bent parts on both sides of the paper cup in order to release the lock, the inconvenience that the lock cannot be released by a single opening operation and a straight cut is formed in an arc cut However, there is a problem that the locking force by the locking piece becomes a small force without exerting the hinge locking locking force, or the locking force cannot be obtained. (See Patent Document 3 Japanese Patent Laid-Open No. 2002-154560)

  In order to solve the above problems, the present invention carries a cup-shaped container containing a liquid beverage such as juice or cola, a granular food or drink such as a pockcorn, or a semi-viscous food or drink such as ice cream. Proposes a container lid that can be reused as needed without causing the contained contents to spill and leak, and can be removed by a single opening operation when the contained contents are removed. To do.

  The cover material is a substantially triangular cardboard, and a substantially triangular top portion and a linear notch are provided opposite to the inside of the substantially triangular top portion, and a diagonally inclined notch and a fold line reaching the outer edge are provided continuously to the notch. A circular plate is mounted on the rear surface of the lid material and overlapped, and the folding line is folded, and the notch and the obliquely tilted notch are separated by folding to form a contact plate with the top plate. Solve the problem with the container lid.

  The lid member and the circular plate are connected by a connecting piece, and the center of each container can be overlapped. A bending portion is provided in the lateral direction of the boundary between the top plate and the circular plate, and polymerization is performed. It is a container lid that can solve the problem by displaying a center point on the top plate and the circular plate so that they can be bent and polymerized easily.

The present invention folds a fold line provided in a lid material, folds and separates the notches, and covers the cup lid with a container lid on which the top plate and the contact locking piece are formed, so that the container opening is covered with the top plate. And a circular plate, the abutment locking piece is locked immediately below the outer peripheral edge of the flange portion, and the circular plate is also pressed by the top plate to lock the container opening as a hinge lock locked state. Can be sealed. The hinge lock is locked in the three directions of the cup-shaped container, and is not locked in the diametrical direction.

To unwrap and open the container opening, pick up the contact locking piece that locks in one of the three directions, and the hinge lock locking state is released. The hinge locking state of the contact locking piece is also released, and the container opening can be easily unsealed. In addition, the container lid can be manufactured at low cost because a base material can be obtained by punching out a piece of cardboard.
The lid for a container in which a lid provided with a top plate and a circular plate are connected by a connecting piece can be easily attached to the center of the circular plate at the center of the back of the lid without dissipating the circular plate. There is also an effect.
Since the manufacturing process of the lid material and the circular plate can be performed in one step of punching out a single cardboard, an effect that can be obtained at low resource and cost can be expected. In addition, the container lid of the present invention can be printed on the surface with a cosmetic effect.

The container lid according to the present invention is formed by punching one cardboard once, and the cover material is a substantially triangular cardboard as a base material. A cut is provided, a slanting cut and a fold line reaching the outer edge are provided continuously to the cut, and a circular plate is attached to the cut on the back surface of the lid material, and the fold line is folded and bent, It is possible to obtain a container lid formed by separating the cut and the oblique cut by bending and forming the top plate and the contact locking piece.
When working efficiency is taken into consideration, the top plate and the circular plate can be prepared by punching different cardboards.
As the best mode for carrying out the invention, it is desirable to simultaneously attach a connecting piece for connecting the lid member and the circular plate when punching out one cardboard and manufacturing the lid member and the circular plate.
