Cup with anti-cap function

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cup having a lid release preventing function, and more particularly, to a cup having a lid release preventing function to prevent a lid from being detached from an inlet of a cup.

Disposable cups for packaging and selling cold food and beverages (coffee, juice drinks, etc.) are made of various materials. Such disposable cups are mainly made of plastic, paper, and the like.

This disposable cup has a lid that covers the upper inlet of the cup to prevent foreign matter from being mixed into the cup or the contents inside the cup are shaken and flooded out of the cup.

On the other hand, the inlet portion of the cup body is filled with food or the like in the inside of the cup, and then heat and pressure are applied along the periphery of the inlet to completely seal the inside of the cup with external air. The lid covers the sealing part.

In most cases, the user can take the beverage inside the cup by threading the straw through the hole formed in the lid in the unsealed state.

Disposable cups containing conventional contents are frozen and / or refrigerated in order to maintain freshness of the contents or on the move for refrigeration / freezing of the beverage and / or at the point of sale. In the disposable cup that is frozen and / or refrigerated, the gas remaining in the cup shrinks, causing the sealing portion to contract or deform around the center.

Referring to FIG. 1, as the sealing part 1 contracts, the cup inlet 2 shrinks and the lid 3 and the cup inlet 2 are not brought into close contact with each other and the space between the outer end of the cup and the lid 3 There arises a problem that the lid 3 is detached from the cup even when a very weak impact occurs when the cup is stacked, moved or taken out from the storage place.

That is, the diameter D2 of the cup inlet 2 after shrinkage becomes smaller than the diameter D1 of the pre-shrinkage cup inlet 2, so that the lid 3 can not be tightly coupled with the inlet of the cup, and the cup inlet 2 and the lid 3 So that the lid 3 can be separated from the cup.
