Description

Self-sealing container

Technical field

The present invention relates to a container, and mainly to a container which is self-sealing by folding, including a paper cup and a plastic cup.

Background technique

For the paper cups used in fast food restaurants, their design is divided into two parts, the cup body and the plastic cover. The cup body has a narrow cylindrical design, which can be inserted into the other one for convenient transportation and Store. The edge of the cup is rolled up, making it easy for the plastic cover to cover the cup. The cost is increased because of the need to make a plastic cover.

Summary of the invention

The object of the present invention is to overcome the deficiencies of the prior art, and to provide a self-sealing container by folding, which does not require a cover, and is a design for extending the cover on the container, and the cover can be engaged and opened, which is particularly suitable for application in use. Disposable paper cups and plastic cups. For example, the kind of paper cup of McDonald's soda.

The technical solution of the present invention is that the container is made of paper or plastic, wherein the container opening is provided with a foldable flap structure for sealing the opening, the flap structure comprising more than one flap, the flap After being folded into the opening, the flaps are superimposed on each other and fastened together, the opening is sealed, so that the objects in the container do not flow out, and the flap is folded and opened to realize the opening and opening of the container opening.

The technical solution also includes:

The container is a cup, the cup is made of paper or plastic, the cup comprises a cup body and a cup bottom, and the cup mouth of the cup body is provided with a foldable flap structure for sealing the cup mouth, the flap structure comprises more than one The cover flap, after the flap is folded into the mouth of the cup, the flaps are superimposed on each other and fastened together, the cup mouth is sealed, so that the liquid in the cup does not flow out, and the flap is folded and opened to realize the mouth of the cup. Cover and open.

The foldable flap structure comprises a first flap, a second flap and a third flap. The flap has a shape of a dome, a dome-shaped connection is formed between the flap and the flap, and a slit is formed on the top of the dome. One side of the gap is a pressure flap, and the pressure flap is provided with a convex pressing groove, the end of the pressure flap is a button, the other side of the gap is a pressured flap, and the pressure flap is provided with a folding indentation and a folding pressure. Above the mark is a pressed strip, the pressed strip can be folded relative to the pressed flap, and the pressed strip is further provided with a curved pressing groove, and the pressing groove of the pressed strip and the pressing groove on the pressing flap are mutually arched together a fold indentation is provided at a fold of the first flap, the second flap and the third flap, and the flap is folded into the cup mouth by folding indentation, and after folding, the flaps are sequentially pressed together in the same direction. The pressure flap of the latter flap is pressed against the pressure groove of the pressure strip of the previous flap, and the buckles are also snapped into each other in the gap, forming a lid to seal the cup to become a cup having a lid.

The cup has a truncated cone shape, and the diameter of the cup mouth is larger than the diameter of the bottom of the cup. The area of the flap is larger than the area of the cup. The flap is folded into the mouth of the cup and then cuts down due to the pressure to form a lid with tension.

After the first flap, the second flap and the third flap are folded into the lid of the cup, the shape of the cap is an arc-shaped triangle.

The folded indentation is curved.

One of the flaps is provided with a cross-hatch for inserting a straw.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

Example 1 (round table paper cup)

As shown in Figures 1-4, the cup consists of a cup bottom 1, a cup 2, a first flap 4, a second flap 5 and a third flap 6. Up to three equally aliquots (360 degrees apart) of the foldable flaps for sealing the cup mouth, namely the first flap 4, the second flap 5 and the third cover, extend upwardly from the cup opening of the cup 2 The flap 6, the three flaps (4, 5, 6) are continuous undulating (the scorpion and the scorpion are combined), and the flaps (4, 5, 6) are the same size and structure and shape, and the flaps are covered. 5, 6) After folding into the mouth of the cup, the flaps (4, 5, 6) are superimposed on each other and fastened together, and the cup mouth is sealed, so that the liquid in the cup does not flow out, and the flap is covered (4, 5, 6) By folding and opening, the lid of the cup is opened and opened.

The first flap 4 is composed of a first button 41, a first gap 42, a first folding indentation 43, a first pressure flap 44, a first pressure strip 45, a first pressure groove 46, a first folding indentation 47, The first pressure-receiving lobes 48 and the first pressure-receiving groove 49 are formed; the second cover lobes 5 are composed of a second button 51, a second gap 52, a second folding indentation 53, a second pressure-pressure flap 54, and a second pressure-receiving strip 55. The second pressure groove 56, the second pressure point 57, the second pressure-receiving valve 58 and the second pressure-receiving groove 59; the third cover flap 6 is composed of a third button 61, a third gap 62, and a third folding pressure The mark 63, the third pressure flap 64, the third pressure strip 65, the third pressure groove 66, the third folding indentation 67, the third pressure receiving flap 68, and the third pressing groove 69 are composed.

Taking the first cover flap 4 as an example, a first gap 42 is provided on the top of the dome of the cover flap. The first gap 42 is on the side of the first pressure flap 44, and the end of the first pressure flap 44 is the first button 41 ( The arcuate shape), the other side of the first gap 42 is the first pressure-receiving lobes 48, the first pressure-receiving lobes 48 are provided with a first folding indentation 47, and the first folding indentation 47 is the first pressure-receiving strip 45, the first pressure-receiving strip 45 is foldable relative to the first pressure-receiving flap 48, and the first pressure-receiving strip 45 is further provided with a first pressure groove 46 which is arched, and the first cover flap 4 (the second cover flap 5) The fold of the same as the third flap 6 is provided with a circular first fold indentation 43. The first flap 4 is further provided with a first pressing groove 49 which is arched, and the second flap 5 is provided with a arch The second pressing groove 59, the third cover flap 6 is provided with a third pressing groove 69 for arching.

The first flap 4, the second flap 5 and the third flap 6 are respectively folded into the cup through the first folding indentation 43, the second folding indentation 53, and the third folding indentation 63, and after folding, the first cover The flap 4, the second flap 5 and the third flap 6 are sequentially laminated together in the same direction, and the pressure flap of the latter flap is pressed against the groove of the pressure strip of the previous flap, that is, the second press The groove 59 and the first pressure groove 46 are arched (convex) to be pressed together, and the third pressure groove 69 and the second pressure groove 56 are mutually arched (convex) to be pressed together, first The pressing groove 49 and the third pressure groove 66 are mutually arched (convex) to be pressed together, because the mutual convex force is increased, It is more sealed, and the buttons are also snapped into each other in the gap, forming a lid to seal the cup to become a cup with a lid (see Figures 2 and 5).

Since the cup has a truncated cone shape, the diameter of the cup mouth is larger than the diameter of the bottom of the cup, and the area of the flap is larger than the area of the cup. The flap is folded into the mouth of the cup and then cuts down due to the pressure to form a lid with tension.

Folded indentations and fold indentations are usually thinner than cups and pressure flaps.

working principle

The cup is made to be open (see Figure 1). When in use, put a liquid (such as soy milk), then fold the flap, seal the cup (see Figure 2), and then insert the straw at the cross.

Characteristics

The original plastic cover was saved. The part that extends out of the cup is called a flap, and the flaps are combined to form a lid, which is convenient and easy to use.
