Description

[Detailed description of the invention] This invention is a cup-shaped container made of a single or composite material such as plastic, paper, or aluminum foil, filled with contents, and then sealed with adhesive. This invention relates to an easy-to-open sealed cup containing liquid or powder that does not require opening.

Conventionally, cup-shaped containers such as those described above have a horizontal flange around the opening, and the lid is sealed uniformly and easily on the flange surface, and a portion of the container is opened to reveal the contents before use. When pouring things out or drinking drinks, the opening part is often larger than necessary and the contents tend to scatter or spill out.To avoid this, small holes are made in the lid in advance. A hole is made and sealed with another seal piece, and when used, the seal piece is peeled off or a straw is inserted through the seal piece. However, this method was not satisfactory, as the manufacturing process became complicated and the use became troublesome.

The present invention aims to improve the above-mentioned disadvantages of conventional sealed cup-shaped containers by making it possible to easily and reliably open only a portion of the container's sealing lid, and to create an easy-to-open seal that allows the contents to be taken out without scattering and spilling out. It provides a cup.

The first feature of the present invention is that a partition flange is provided at the opening of the cup-shaped container to form a small opening to serve as a spout or drinking spout. In this case, a flange is provided around the opening of the cup, and the partition flange is provided flush with the flange.

The second feature is that when the lid is adhesively sealed to the opening flange surface and the compartment flange surface, the adhesive strength of the lid at the small opening is weaker than other parts to make it easier to open. be.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a cup-shaped container body 1 in the first embodiment, in which a circular opening 2 and a small opening 3 protruding outward from the circular opening 2 are formed, and a wide opening is formed around the periphery of the opening 2. A narrow flange 5 is provided on the periphery of the flange 4 and the small opening 3, and a wide dividing flange 6 is provided between the opening 2 and the small opening 3.

FIG. 2 shows a lid 10 that covers the opening 2 and the small opening 3 after the cup-shaped container body 1 is filled with the contents L.
is a cross-sectional side view of the main part when the flange surface is thermally bonded and sealed, and the lid 10 has a tongue piece 11 extending outward from the small opening 3, and the lid 10 has a tongue piece 11 extending outward from the small opening 3. By pinching the tongue piece 11 and pulling it up as shown by the dotted line, the weak adhesion at the narrow flange 5 of the small opening 3 is broken and the lid 1 is removed.
0 is peeled off, but the small opening 3 can be reliably opened because it is firmly adhesively held on the wide partition flange 6 surface and prevents further peeling.

FIG. 3 is a perspective view of a cup-shaped container body 1' in the second embodiment, in which a substantially rectangular opening 2' is arranged so as to form two small openings 3', 3' at opposite corners. There are two partition flanges 6', 6', and a partition 7 which divides the container into two, the upper edge of which has a flange 7', a peripheral flange 4' of the opening 2', a partition flange 6', It is connected flush with the surface of 6'. In this cup-shaped container body 1', two storage parts are filled with contents of the same or different kinds, and the lids are adhesively sealed.

FIG. 4 is a plan view of the lid 10' in this case, and the hatched portion indicates the heat-adhesive seal portion. In other words, the lid 1
0' is thermally sealed, but especially the small openings 3',
The seal width at the peripheral flange 4' surrounding the flange 3' is set to a narrow seal line 12 that is less than 1/2 that of other parts. The small opening 3' can be opened while tearing the opening 10'.

The lid 1 of the part corresponding to these small openings 3', 3'
0' In order to facilitate opening and opening, perforations are provided in the portion of the lid 10' that corresponds to the compartment flange 6',
A stretched film that is easy to tear parallel to the partition flange 6' may be used as the lid.

As explained above, the easy-open sealed cup of the present invention can be produced at low cost without adding any separate components, and only the small opening can be opened easily and reliably, preventing the contents from scattering and spilling out. This improves the practicality of the container as a sealed container for liquids and powders.
