Abstract
The utility model relates to a sealing structure of container, in particular to a sealing structure of cup shape container, comprising a cup body and cup mouth turned-over edge. Wherein, the lower part of the cup mouth turned-over edge is provided with a piece of lower base plate, the middle part of the lower base plate is provided with a through hole matching with the cup body shape at the lower part of the cup mouth turned-over edge; the lower base is provided with a lower base plate handle which extrudes longitudinally; the upper parts of the cup mouth turned-over edge and the lower base plate are respectively provided with sealing film which is affixed with the cup mouth turned-over edge and the upper surface of the lower base plate; the sealing film is provided with a free sealing film drawing sheet extruding longitudinally on a place corresponding to the lower base plate handle. The utility model adopts the lower base plate to add the affixing area with the sealing film, so as to guarantee the affixing intensity of the sealing film without increasing the cup mouth turnover edge.
Description
Technical field: the utility model relates to a kind of enclosuring structure of container, is meant a kind of enclosuring structure of cup-shaped receptacle especially.
Background technology: at present, raising along with science and technology development and people's living standard, both can be as external packing, can be used as disposable cup-shaped commodity packaging quilt more and more widely that container uses again promotes and uses, as water tumbler, the jelly cup, instant noodle bowl etc., these non-returnable containers are when the life for us offers convenience, also exist some drawbacks, as for seal film and form the higher adhering and sealing layer of intensity, the rim of a cup flange of this type of cup-shaped receptacle must be widened, and just need to adopt the technology of once-forming for the rim of a cup flange that forms broad, this is out of question for materials such as plastics and foamed plastic; But for roll the cup-shaped receptacle that forms with cardboard, its rim of a cup flange is difficult to form bigger upper surface, seals film so can't paste securely, thereby has limited its use as goods packing container; Though can address the above problem with paper pulp is wet-formed, the wet-formed requirement height to equipment, energy consumption of paper pulp causes its cost of manufacture height, has limited its use.
Summary of the invention: the purpose of this utility model provide a kind of to the no specific (special) requirements of rim of a cup flange size and with sealing the film bind strength enclosuring structure of high cup-shaped receptacle.
The purpose of this utility model is achieved in that a kind of enclosuring structure of cup-shaped receptacle, comprise cup, rim of a cup flange, wherein be provided with the infrabasal plate that a slice middle part has the through hole that matches with rim of a cup flange bottom cup shape in the bottom of rim of a cup flange, infrabasal plate is provided with the infrabasal plate handle that radially protrudes; Be provided with respectively the film that seals that upper surface with rim of a cup flange and infrabasal plate is pasted together on the top of rim of a cup flange and infrabasal plate, seal the corresponding position of substrate handle, film up and down and be provided with one and radially protrude and end seals the film pulling-on piece freely.
Because the utility model adopts infrabasal plate to increase and seals the bond area of film, thereby can guarantee to seal the bind strength of film on the basis that does not increase the rim of a cup flange.
Description of drawings: Fig. 1 is a birds-eye view of the present utility model
Fig. 2 is a upward view of the present utility model
Fig. 3 is that the A-A of Fig. 1 is to cutaway view
Fig. 4 is the local structure for amplifying scheme drawing of the I portion of Fig. 3
The name of number in the figure is called: 1-seal film, 2-seal film pulling-on piece, 3-infrabasal plate handle, 4-collude finger-hole,
