Abstract
The utility model discloses a turn -up structure for jar body, including jar body and a lid, the material that the jar body adopted is paper material, jar body top inward flange is equipped with the snap ring, the snap ring is solid construction, the snap ring physically is circular -arc in center one side to the jar, the lid is including face lid and boss, the boss is located face lid below, the boss with the snap ring forms interference fit, the snap ring does jar body top inward flange inwards curls and forms, and the crimping degree is greater than 360 degrees. The utility model discloses a jar body edge in the paper sets up real cardioid snap ring for the lid becomes interference fit with jar bodily form, has effectively improved a lid and jar compactness that the body combines.
Description
Technical field
The utility model relates to the technical field of packaging, particularly relates to a kind of bead structure for tank body.
Background technology
In the prior art, the storage packaging of tealeaves often adopts jar, and existing jar adopts the material of irony or papery usually, adopts iron flask, and what lid and tank body can coordinate compares closely, and such lid is not easily thrown off from tank body, and tightness is good.But in prior art products, also adopt the jar of papery in a large number, the jar of papery is due to the soft restriction of material, lid is just more loose comparatively speaking with the cooperation of tank body, in view of this, the present inventor studies and devises a kind of bead structure for tank body, and this case produces thus.
Utility model content
The purpose of this utility model is a kind of bead structure for tank body, by arranging the snap ring of solid shape at the vessel edge of papery, makes lid and tank body form interference fit, effectively to improve the compactness that lid is combined with tank body.
To achieve these goals, the technical scheme in the invention for solving the technical problem is:
A kind of bead structure for tank body, comprise tank body and lid, the material that described tank body adopts is papery material, described tank body top inward flange is provided with snap ring, described snap ring is solid construction, and described snap ring is arc-shaped to side, tank body center, and described lid comprises cover and boss, described boss is located at below described cover, and described boss and described snap ring form interference fit.
As the optimal way of embodiment, to be that described tank body top inward flange is inwardly curling form described snap ring, and crimpness is greater than 360 degree.
As the optimal way of embodiment, the rectangular shape in junction of described cover and described boss or radiussed.
As the optimal way of embodiment, the rectangular shape in described boss bottom edge or radiussed.
As the optimal way of embodiment, described boss side surfaces is vertical shape or cone-shaped.
As the optimal way of embodiment, described tank body is cylindrical shape, and described lid is circular.
As the optimal way of embodiment, described tank body is square, and described lid is square.
Because a kind of bead structure for tank body of the utility model have employed above-mentioned technical scheme, namely tank body and lid is comprised, the material that described tank body adopts is papery material, described tank body top inward flange is provided with snap ring, described snap ring is solid construction, and described snap ring is arc-shaped to side, tank body center, and described lid comprises cover and boss, described boss is located at below described cover, and described boss and described snap ring form interference fit; Lid of the present utility model closely can be engaged in above tank body, and not easily unclamp.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic cross-section of the utility model tank body.
Detailed description of the invention
As shown in Figures 1 and 2, the utility model discloses a kind of bead structure for tank body, comprise tank body 1 and lid 2, the material that described tank body 1 adopts is papery material, and described tank body 1 top inward flange is provided with snap ring 11, and described snap ring 11 is solid construction, described snap ring 11 is arc-shaped 111 to side, tank body center, described lid 2 comprises cover 21 and boss 22, and described boss 22 is located at below described cover 21, and described boss 22 forms interference fit with described snap ring 11.
As the optimal way of embodiment, described snap ring 11 forms for described tank body top inward flange is inwardly curling, and crimpness is greater than 360 degree.Adopt the Snap ring structure of solid curling shape, easy lid, sealing and resilient effect can be played.
As the optimal way of embodiment, the rectangular shape in junction of described cover 21 and described boss 22 or radiussed.
As the optimal way of embodiment, the rectangular shape of described boss 22 bottom margin or radiussed.
As the optimal way of embodiment, described boss 22 side is vertical shape or cone-shaped.
As the optimal way of embodiment, described tank body 1 is cylindrical shape, and described lid 2 is circular.
As the optimal way of embodiment, described tank body 1 is square, and described lid 2 is square.
When using the technical solution of the utility model, lid is covered on tank body, and boss is taken advantage of a situation from the side of snap ring arc-shaped and slided, because snap ring adopts the structure of solid curling shape, make snap ring closely can be pressed in the side of boss, and then the firm power of the contact that effectively improve lid and tank body.
The above, be only the utility model preferred embodiment, therefore the scope that the utility model implements can not be limited according to this, the equivalence namely done according to the utility model the scope of the claims and description change with modify, all should still belong in scope that the utility model contains.
