Description

Sealing film opening device

Technical Field

The present invention relates to an opening device, and more particularly to a sealing film opening device.

Background

Traditionally, when hand cup ice products are sold in beverage shops, pearl milk tea is sealed by a film sealing machine, when a user drinks with a straw, the straw is punctured and sealed for drinking, and is discarded in a recycling bin after being used up, however, as too many straws are discarded in the environment and the sea, and the straws cannot be reused due to difficult recycling, the problems of too much marine pollution and plastic wastes are caused. And therefore governments have come to impose restrictions on the use of disposable straws.

Therefore, the use of the environmental protection straw is popular, but the environmental protection straw, such as a glass straw, a stainless steel straw, a paper straw, a silica gel straw and the like, is almost not used as a tip, so that the sealing film cannot be smoothly cut to drink when people drink the hand-operated beverage in the market, and if the tip of the traditional straw is used for opening, the opening of the sealing film is different in size due to the strength, the inserting direction and the like, so that the beverage leaks.

In view of the above, it is a very important objective to make mouth openers that are portable and have a stable and appropriate opening size.

Disclosure of Invention

The invention aims to provide a sealing film opening device which is simple in structure, easy to carry and hold and capable of effectively forming an opening on a sealing film.

To achieve the above objects, an opening sealing device according to an embodiment of the present invention includes a hollow cylinder, a holding portion and a saw-tooth structure; the hollow cylinder is provided with a first opening, a second opening and an outer tube wall surface; the holding part is arranged on the wall surface of the outer tube and protrudes outwards from the wall surface of the outer tube; the sawtooth structure is formed on at least one part of the periphery of the second opening.

The sealing film opening device is simple, easy to carry and easy to hold, and can effectively form an opening on the sealing film.

Referring to fig. 1, a film sealing and opening device 100 according to an embodiment of the present invention includes a hollow cylinder 110, a holding portion 120, and a saw-tooth structure 130. The detailed structure thereof is explained as follows.

With continued reference to fig. 1 and fig. 2A-2E, the hollow cylinder 110 has a first opening 111, a second opening 112 and an outer wall 113; the hollow cylinder 110 is a hollow cylindrical body penetrating up and down, in one embodiment, the shape of the hollow cylinder 110 is a cylinder, an elliptical cylinder, a polygonal cylinder or a combination of the above shapes, in one embodiment, the geometric shape includes a circle, an ellipse, a square and a combination of the above figures, and the polygon includes a square, that is, the shape of the hollow cylinder 110 is not limited. In another embodiment, the shape of the first opening 111 is circular (see fig. 2A), elliptical (see fig. 2B), square (see fig. 2C), polygonal (see fig. 2D), geometric (see fig. 2E), or a combination thereof. It is understood that the shape of the second opening can also be circular, oval, square, polygonal, geometric or a combination thereof (not shown). The length and shape of the hollow cylinder 110 are not limited to fig. 1 or fig. 2A-2E, and in an embodiment, the shape of the hollow cylinder 110 may be a curved shape, a spiral shape (as shown in fig. 3), or an arbitrary shape.

Continuing with the above description, with continued reference to fig. 2A-2E, the holding portion 120 is disposed on the outer tube wall surface 113 and protrudes outward from the outer tube wall surface 113. In one embodiment, the holding portion 120 may be at least one of a doll with an arbitrary shape (see fig. 2A and 4A) and a plaque with an arbitrary shape (see fig. 4B, 4D, 4E and 4F). The function of the holding portion 120 enables the film sealing and opening device 100 to generate a force arm, which is more labor-saving for a user to use the film sealing and opening device 100 to cut a film. In the above embodiment, the hollow cylinder 110 is integrally formed. In another embodiment, referring to fig. 5A, the hollow cylinder 110 includes a first side piece 116 and a second side piece 117, and the first side piece 116 and the second side piece 117 are joined to form the hollow cylinder 110. In another embodiment, please refer to fig. 5B, fig. 5C, fig. 5D, and fig. 5E, wherein fig. 5C is a partially enlarged schematic view of fig. 5B; fig. 5E is a partial enlarged view of fig. 5D, the film sealing and opening device further includes a first joint portion 118 and a second joint portion 119, the first joint portion 118 is formed on the first side piece 116; a second joint 119 is formed on the second side piece 117, wherein the first side piece 116 and the second side piece 117 are butted by the first joint 118 and the second joint 119 to form the hollow cylinder 110. In various embodiments, the holding portion 120 may be integrally formed with the hollow cylinder 110 (as shown in fig. 1 to 5A) or fastened to the hollow cylinder 110 (as shown in fig. 5B and 5D).

Referring to fig. 4C, fig. 4C is a partial enlarged view of fig. 4B, and the sawtooth structure 130 is formed on at least a portion of the periphery 114 of the second opening 112. That is, not 100% of the peripheral edge 114 of the second opening 112 is formed with the saw-tooth structure 130, i.e., a small portion of the peripheral edge 114 is flat (non-saw-tooth), so that the cut film does not fall to the bottom of the cup, but at least a portion of the cut film is connected to the sealing film. In one embodiment, the portion of the second opening 112 having the saw-tooth structure 130 on the periphery 114 is between ten percent and ninety percent of the length of the entire periphery 114. In addition, in an embodiment, as shown in fig. 6, the second opening 112 has an inclined surface 115 with a tapered opening, that is, the hollow cylinder 110 forms an inclined surface 115 downward from the periphery 114 of the second opening 112, so that the length of the periphery 114 of the second opening 112 is smaller than the length of the periphery of the hollow cylinder 110. Alternatively, in another embodiment, the area size of the first opening 111 is larger (as shown in fig. 6), equal to (as shown in fig. 4A), or smaller (as shown in fig. 7) than the area size of the second opening 112.

In another embodiment, referring to fig. 8, the holding portion 120 may also be formed by a plurality of protrusions (e.g., small bumps) protruding from the outer wall surface 113 of the hollow cylinder 110. In another embodiment, referring to fig. 9A, the present invention may further include a suction pipe 140 engaged with the hollow cylinder 110 through the second opening 112 of the hollow cylinder 110, as shown in fig. 9B, wherein the holding portion 120 includes but is not limited to those shown in the drawings.

According to the sealing film opening device, the friction force between the fingers of the user and the device is increased by utilizing the holding part. In addition, if the holding part is a doll figure or a decorative sheet which is easy to hold, the holding part can generate a force arm to lead the user to save more labor in use. The shape of the hollow cylindrical body, the shape of the opening and the shape of the holding part of the sealing film opening device can be designed into different shapes, and the design feeling is added besides the practicability. Moreover, the hollow column body of the invention is a hollow column main body which is communicated up and down, and can be used as a short straw after the sealing film is cut off, or can be used together with another straw, thus being very practical and convenient.

In summary, the sealing film opening device of the present invention is simple and easy to carry and easy to hold, and can effectively form an opening for the sealing film.

The above-mentioned embodiments are merely illustrative of the technical spirit and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the content of the present invention and to implement the same, so that the scope of the present invention should not be limited by the above-mentioned embodiments, and that all equivalent changes and modifications made in the spirit of the present invention should be covered by the scope of the present invention.
