Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an easy-open container.

[0002]

[Prior art]

 Conventionally, as an easy-open container, the entire container is made of a soft metal material such as aluminum, and a ring-shaped handle that is installed horizontally from one end of the top surface of the top wall is erected and pulled backward, It is known that the top wall can be ruptured and removed along the recessed groove-shaped rupture portion formed on the peripheral edge, and a wide opening can be obtained.

[0003]

[Problems to be solved by the device]

 However, since the force applied to the cut parts is dispersed due to the structure of these containers, a considerable amount of force is required at the time of opening, and it is difficult to open, and it is extremely difficult for the elderly, children, etc., who have particularly weak power to open. There was a drawback. In addition, since it requires a force to open the package, there is also a drawback that liquid stored items are likely to be scattered during opening. The present invention aims at proposing an excellent container that overcomes the above-mentioned drawbacks of the prior art.

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the container of the present invention has a container body 2 having an upper end opening in which a peripheral wall is erected from a peripheral edge of a bottom wall, and an outer periphery of a tubular portion 4 is fixed by welding to an upper end of an inner peripheral wall of the container body 2. And a lid 3 formed by extending a top plate portion 5 that closes the opening of the upper end surface of the container body 2 from the lower edge of the tubular portion 4 and the lid body 3 is made of synthetic resin. In addition, an upper layer 6 formed by breaking portions 8 for cutting and removing the top plate portion, and a lower layer 7 composed of a metal thin film in which a synthetic resin layer for adhesion is laminated The fractured portions 8 are formed along the outer peripheral edge of the top plate portion 5, and a part of the fractured portion 8 is projected into the tubular portion to form a pair of finger hook portions. The first ruptured portion 8a defining 9 and 9 and the top plate portion 5 from the central position between the finger hooks 9 of the ruptured portion 8a. The welded portion 10 is composed of a second fractured portion 8b that bisects and reaches a facing position, and the welded portion 10 includes the first welded portion 10a along the lower surface of the first fractured portion 8a in the top plate portion 5 and the second welded portion 10a. The container is provided with a second welded portion 10b along the lower surface of the fractured portion 8b, and is configured as an easily openable container.

[Embodiment of the invention]

 Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 show an embodiment of the present invention, in which 1 denotes an easily openable container. The container 1 comprises a container body 2 and a lid body 3.

The container 2 has a bottomed cylindrical shape formed of a synthetic resin or a cover of resin and metal.

In addition, the lid body 3 is fixed to the container body 2 in an airtight manner by welding and fixing the outer periphery of the cylindrical portion 4 to the inner periphery of the upper end of the peripheral wall of the container body 2 by a welding method such as ultrasonic welding. A top plate portion 5 that closes the upper end surface opening of the container body 2 is extended from the lower edge of the portion 4. In addition, the lid 3 includes an upper layer 6 made of synthetic resin and a lower layer 7 made of a metal thin film in which a synthetic resin layer for adhesion (not shown) is laminated, and a portion corresponding to the cutting of the top plate portion 5. Laminated portions are welded and laminated at required positions, and a fractured portion 8 for removing the fractured top plate portion is formed on the upper layer 6.

The rupture portion 8 has an annular shape along the outer peripheral edge of the top plate portion 5, and a part of the rupture portion 8 protrudes from the tubular portion 4 to define a pair of finger hooks 9 and 9, which is a first rupture portion. It is composed of a portion 8a and a second fractured portion 8b that divides the top plate portion 5 from the center position between the finger-hooking portions of the first fractured portion 8a to reach the opposing position. In the present embodiment, each fractured portion is formed in a V-groove shape having a flat portion at a required interval as shown in FIG. 1 or FIG. 4, but the present invention is not limited to this, and some connection portions may be formed. Alternatively, the other part may be formed into a perforated shape by completely cutting it, and the point is that the left and right of the fractured part can be easily separated. Further, the welded portion 10, which is the welded portion of the upper layer 6 and the lower layer 7, has a first welded portion 10a along the lower surface of the first fractured portion 8a of the top plate portion 5 and a welded portion 10 which is the 2 The second welded portion 10b is formed along the lower surface of the fractured portion 8b, and the welded portion is not provided in the first fractured portion 8a portion of each finger hooking portion 9 and 9 and the inner bounding portion thereof. As a method of forming the container 1, for example, as shown in FIG. 4a, an upper layer 6 in which a fractured portion 8 is formed in advance and a lower layer 7 made of a metal thin film in which a synthetic resin layer for adhesion are laminated are ultrasonically applied at required portions. After welding by a method such as gluing, the tubular portion 4 is press-formed so as to stand up in a tubular shape having an outward flange at the upper end as shown in FIG. 4b. It can be formed by welding to the upper end.

In the case of using the container 1 configured as described above, for example, when one of the finger hooks 9 is grasped and pulled backward, the first welding portion is provided between the upper layer 6 and the lower layer 7 of the top plate portion 5, respectively. 10a Since there is the second welded portion 10b, and the metal layer of the lower layer 7 is a thin layer, the top plate portion 5 is cut in half along the fractured portion, and the separation angle between the first and second fractured portions is Since it is narrow, it is possible to remove the rupture of the top plate portion 5 on the other half with a small force. Similarly, the other half of the top plate 5 is broken and removed. At this time, since the portion of the second fractured portion 8b has already been fractured, the fracture can be removed more easily.

[Effect of the invention]

 As described above, the easy-open container of the present invention has the above-mentioned configuration, and in particular, is made of synthetic resin and is bonded to the upper layer 6 formed with the breaking portion 8 for cutting and removing the top plate portion. The lower layer 7 composed of a metal thin film in which synthetic resin layers for laminating are laminated, and a welding portion 10 which is welded at a required portion including a cutting relevant portion of the top plate portion 5 is provided to be laminated. The first breaking portion 8a is formed in an annular shape along the outer peripheral edge of the top plate portion 5 and a part thereof is projected into a cylindrical portion to define a pair of finger hooks 9 and 9, and each of the breaking portions 8a. The top plate 5 is divided into two parts from the center position between the finger hooks 9 to the opposite position, and the welded part 10 extends along the lower surface of the first break part 8a of the top plate 5. Since the first welded portion 10a and the second welded portion 10b along the lower surface of the second fractured portion 8b are provided, the top plate portion can be widened. When opening the mouth, it can be easily opened with a small force, and there is no risk of inconvenience such as scattering of stored items when opening. It is also possible to store food items inside and heat and cook in a microwave oven.
