Abstract

The invention discloses a seal cover of a food packaging container. The seal cover comprises a cover body, and a pull ring used for opening is arranged on the cover body and connected with the cover body into a whole through at least one stand column; the cover body is provided with a first cracking trail and a second cracking trail, wherein the first cracking trail and the second cracking trail intersect at one intersecting point, the second cracking trail is in a closed curve, and the first tracking trail is linear and is located inside a closed region formed by the second cracking trail. Only one intersecting point of the first cracking trail and the second cracking trail is arranged. The stand columns are located nearby the intersecting point and located inside the closed region formed by the second cracking trail. When the pull ring is pulled by external force, the pull force is transmitted to the part nearby the intersecting point of the cover body through the stand columns, in this way, the cover body cracks along the first cracking trail and the second cracking trail from the part nearby the intersecting point to form an opening, and then the seal cover is opened. The seal cover is simple and practical and can be easily opened while a seal effect is achieved, and using of consumers is facilitated.

Description

The seal cover cap of food container

Technical field

The present invention relates to a kind of food container annex, be specifically related to a kind of seal cover cap of food container.

Background technology

Along with the prosperity in expanding economy and market, prepackaged food kind is also more and more abundanter, and various product is as many as stars.Wherein, a lot of food container adopts seal cover cap to realize sealing, and for ensureing its sealing effectiveness, guarantee, in transportation, seepage and breakage to occur, seal cover cap generally all designs durable.But the design of this undue consideration sealing reliability, often causes again seal cover cap to open difficulty, makes troubles to the use of customer.

Summary of the invention

Technical matters to be solved by this invention is to provide a kind of seal cover cap of food container, and it can make seal cover cap be more prone to open, and facilitates customer to use.

For solving the problems of the technologies described above, the technical solution of the seal cover cap of food container of the present invention is:

Comprise lid; Described lid is provided with the draw ring opened, and draw ring is connected as a single entity by least one column and lid; Described lid is provided with two and intersects at first of the intersection point track and second that breaks and to break track, and second track that breaks is closed curve, and first track that breaks is linear, and first track that breaks is positioned at second and breaks the closed region that track formed; Described first break track and the second intersection point breaking track has and only has one; Described column is positioned near intersection point, and is positioned at second and breaks the closed region that track formed; When described draw ring is subject to external pull effect, this pulling force conducts to the near intersections of lid through column, lid to be broken formation opening along first track and second track that breaks that breaks near intersections, realizes the unlatching of seal cover cap.

Minor increment between described column and intersection point is not more than 5mm.

The thickness of described point of intersection is 0.05 ~ 0.3mm; The thickness of described point of intersection is less than the thickness of lid.

Described first track or second that breaks breaks the line of weakness of track for being formed on lid; Or described first track or second that breaks breaks the intersection that track formed for splitlevel lid.

Described first break track by or depart from the second center of breaking closed region that track formed.

Described first breaks, and track is linearly, polyline shaped or arc shaped.

Described first break track linearly with the build-up curve shape of camber line.

Described first track that breaks is nonocclusive irregular curve shape.

Described column is one; Described column is positioned at first any side of breaking track.

Described column is two; Two columns lay respectively at first left and right sides of breaking track; Or two columns are positioned at first the same side of breaking track.

The material of described lid is the plastics meeting food packaging requirement.

The technique effect that the present invention can reach is:

Compare the seal cover cap of bread and cheese packing container, seal cover cap of the present invention is opened required pulling force and is reduced 40 ~ 80%, while satisfied sealing, antiseep demand, conveniently can open, effectively promote the experience of customer.

The present invention is simple and practical, while playing sealing effectiveness, can realize light unlatching again, facilitates customer to use.

Detailed description of the invention

as Fig. 1shown in, the seal cover cap of food container of the present invention, comprises the lid 1 sealed, and lid 1 is provided with the draw ring 6 opened, and draw ring 6 is connected as a single entity by column 3 and lid 1; Lid 1 is provided with two and intersects at first of an intersection point 2 track 41 and second that breaks and to break track 5, second break track 5 in closed curve ( as Fig. 1in circle), first breaks track 41 in linear, and first track 41 that breaks is positioned at second and breaks the closed region that track 5 formed;

First the break intersection point 2 of track 5 of track 41 and second that breaks has and only has one; The thickness at intersection point 2 place is 0.05 ~ 0.3mm, and the thickness of point of intersection is less than the thickness of lid;

Column 3 is positioned near the intersection point 2 of two tracks 41,5 that break, and is positioned at second and breaks the closed region that track 5 formed;

Preferably, the minor increment between column 3 and intersection point 2 is not more than 5mm;

When draw ring 6 is subject to external pull effect, this pulling force conducts to lid 1 through column 3, lid 1 to be broken formation opening along first track 41 and second track 5 that breaks that breaks, realizes the unlatching of seal cover cap.

Wherein, the track that breaks refer to by the variation in thickness of lid (namely on lid, form line of weakness, as Fig. 9shown in; Or be the intersection of splitlevel lid, as Fig. 1shown in 0) the crackly track when lid is subject to external force that formed.

Column 33 can be positioned at the first right side of breaking track 42, as Fig. 2shown in, also can be positioned at the first left side of breaking track 42, as Fig. 3shown in.

First track 41 that breaks can break by second the center of closed region that track 5 formed, as Fig. 1shown in; First track 42 that breaks also can depart from the second center (namely first breaks track 42 in oblique line shape) of breaking closed region that track 5 formed, as Fig. 2, fig. 3shown in.

as Fig. 4shown in, first track 43 that breaks also can be polyline shaped.

as Fig. 5shown in, first track 44 that breaks also can be arc shaped.

as Fig. 6shown in, first break track 45 also can linearly with the build-up curve shape of camber line.

as Fig. 7shown in, first track 46 that breaks also can be nonocclusive irregular curve shape.

as Fig. 8shown in, draw ring 6 can be connected as a single entity by two columns 331,332 and lid 1; Two columns 331,332 lay respectively at first left and right sides of breaking track 41.Certainly, two columns 331,332 also can be positioned at first the same side of breaking track 41.

Principle of the present invention is: utilize two tracks that break to form stress concentration portion position at its near intersections, pulling force conducts to the near intersections of lid through column, point of intersection is easily broken when being subject to external force, lid to be broken formation opening along first track and second track that breaks that breaks, to facilitate the unlatching of seal cover cap.

Above-mentioned specification sheets and accompanying drawingin order to technical scheme of the present invention to be described, those skilled in the art can carry out various amendment or change to above-described embodiment without departing from the present invention in the case of the inventive idea, therefore, protection scope of the present invention not limit by above-described embodiment.
