Description

Cup lid structure

The present invention relates to a cup lid structure, and in particular to a cup lid that is opened and connected to the upper end of the cup body.

Generally, for any cup of beverage sold on the market, the store must provide another straw for the consumer to pierce the lid of the cup so that the straw can penetrate into the cup and suck the beverage smoothly. However, this use model has the following problems:

1. Straws are usually packed in plastic sleeves. In addition to increasing the packaging process for straws, the use of plastic products is also increased, which not only increases costs, but also causes a burden on the environment.

2. The plastic sleeve of the straw is packaged into a thin strip, which is easy to fall to the ground or be discarded by consumers anywhere, resulting in messy environment.

3. The straw and cover are of different materials, which cause troubles and inconveniences in sorting and recycling, and do not have the concept of environmental protection.

4. Such straws or cup lids do not have the function of re-use or natural decomposition, and do not have the concept of environmental protection.

The main object of the present invention is to provide a cup lid structure, which includes a straw structure for drinking beverages, and can be decomposed in a natural environment with environmental protection benefits.

The objects and effects of the present invention are achieved by the following technologies:

A cup lid structure includes a lid body and two telescopic tube portions; wherein:

The cover system is integrally formed of polylactic acid (PLA) and has an outer surface and an inner surface. The cover body is provided with perforations penetrating the outer surface and the inner surface, and the outer surface is And the inner surface is respectively extended upward and downward along the peripheral edge of the perforation to form a hollow upward protruding joint section and a downward protruding joint section;

The two telescopic tube portions are integrally formed of a polylactic acid material, and include a hollow and communicating telescopic section and an engaging section. One of the engaging sections of the telescopic tube section is sleeved on the cover body. A protruding joint section, and the engagement section of the other telescopic pipe part is sleeved on the lower convex joint section of the cover body, so that the two telescopic pipe parts are respectively engaged and positioned outside the cover body , An inner surface, and communicate with each other through the perforations on the cover body.

The cup lid structure as described above, wherein the telescopic section is of a snake belly tube structure.

The cup lid structure as described above, wherein the engaging section and the upper protruding joint section or the lower protruding joint section are adhered and fixed to each other.

The cup lid structure as described above, wherein the bonding method is bonding by high frequency technology.

In order to provide a more complete and clear disclosure of the technical content, the purpose of the invention and the effect achieved by the present invention, it is described in detail below, and please also refer to the disclosed drawings and numbers:

Please refer to the first figure, which is an exploded perspective view of the cup lid structure of the present invention.

The cup lid structure of the present invention includes a lid body (1) and two telescopic tube portions (2); of which: (please refer to the second and third figures together below)

The cover body (1) is integrally formed of polylactic acid (PLA) and has an outer surface (11) and an inner surface (12) corresponding to the outer surface (11). The cover body (1) is provided with a through-outside The perforations (13) of the surface (11) and the inner surface (12) extend upward along the peripheral edge of the perforations (13) on the outer surface (11) to form a hollow upper protruding joint section (14), and then on the inner surface (12) Extending downward along the periphery of the perforation (13) to form a hollow downwardly protruding joint section (15);

The two telescopic tube sections (2) are also integrally formed of polylactic acid material, and include a hollow and communicating telescopic section (21) and the connecting section (22). One of the telescopic tube sections (2) is based on the connecting section (22). ) Is sleeved on the upper protruding joint section (14) of the cover body (1), and the joint section (22) of the other telescopic tube section (2) is sleeved on the lower protruding joint section (15) of the cover body (1) So that the two telescopic tube portions (2) are respectively positioned on the outer surface (11) and the inner surface (12) of the cover body (1), and communicate with each other through the perforations (13) on the cover body (1).

Among them, in a preferred embodiment of the present invention, the telescopic section (21) of the telescopic pipe section (2) has a structure of adopting a snake belly pipe.

Among them, in a preferred embodiment of the present invention, the engaging section (22) of the telescopic tube section (2) projects on the cover body (1) to protrude the joint section (14) or the lower projected joint section (15). ), They can be further bonded and fixed to each other; among them, the preferred bonding method is high frequency technology bonding.

Based on this design (please refer to the first, second, and third pictures), there is a telescopic tube part (2) structure such as a straw on the cup lid, and there is no need to attach a straw when drinking the beverage. In order to reduce space occupation and facilitate storage and storage, the telescopic section (21) of the telescopic tube section (2) is in a "retracted" state to reduce the volume of the lid; when the lid is intended to be placed in the cup container (3) When pulling up, just pull down the telescopic section (21) of the telescopic tube section (2) on the inner surface (12) side of the cover body (1), so that the telescopic section (21) is in the "extended" position. State, after the cup lid is set on the cup container (3), the bottom end of the telescopic tube portion (2) located on the inner surface (12) side of the lid body (1) can penetrate into the cup container (3) The beverage inside is below the liquid level, at this time, the beverage can be sucked from the telescopic tube portion (2) located on the outer surface (11) side of the lid body (1); of course, depending on the situation, the pull-up position is on the lid body (1) The telescopic tube portion (2) of the telescopic tube portion (2) on the outer surface (11) side, so that the telescopic section of the telescopic tube portion (2) on the outer surface (11) side of the cover body (1) (21) In the "stretched" state, the extension is located on the outer surface (11) side of the cover body (1) The length of the telescoping tube portion (2), and also on the other hand through expansion sections (21) taken bellows structure can freely change the direction of the bellows portion (2), to facilitate suction drinks.

The above are only a part of the embodiments of the present invention, and are not intended to limit the present invention. Those modified according to the creative spirit and characteristics of the present invention with slight changes should also be included in the scope of this patent.

In summary, the embodiments of the present invention can indeed achieve the expected use effect, and the specific technical means disclosed have not only been found in similar products, nor have they been disclosed before the application. They have fully complied with the patent law. Regulations and requirements, applying for an invention patent in accordance with the law, and begging for examination and granting the patent, it is a matter of merits.
