Abstract
The utility model relates to an improvement of vessel sealing structure, in particular to an improved sealing structure of a cup-shaped vessel, comprising a cup body, a cup port flanging, a lower substrate, a sealing film, and a via hole arranged at middle section of the lower substrate and matched with lower section cup body shape of the cup port flanging. Wherein, the upper surface of the lower substrate is provided with a ring shape concave groove along periphery of the via hole. The shape of the ring shape concave groove is matched with the shape of the cup port flanging. Due to a ring shape concave groove which is arranged on the upper surface of the lower substrate and is special for placing cup port flanging, when the cup body and the lower substrate are installed, the cup port flanging is arranged in the ring shape concave groove, and the upper surface of the cup port flanging is aligned with the upper surface of the lower substrate, therefore providing an even paste surface for the sealing film, which makes the sealing film is easy to be pasted. The even upper surface is convenient for placing the utility models mutually, which is beautiful.
Description
Technical field: the utility model relates to a kind of improvement of container closure structure, is meant a kind of enclosuring structure of improved 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; For the applicant who addresses the above problem present patent application has invented that a kind of size to the rim of a cup flange does not have specific (special) requirements and the enclosuring structure of high cup-shaped receptacle with sealing the film bind strength, this structure comprises 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; The enclosuring structure of this cup-shaped receptacle has proposed utility application on January 11st, 2002 to Patent Office of the People's Republic of China by the applicant of present patent application, its application number is 02202004.7, name is called " enclosuring structure of cup-shaped receptacle ", and this application still is in the first trial state at present.The weak point of the enclosuring structure of above-mentioned cup-shaped receptacle is that its upper surface that seals is not a smooth plane, make to paste difficult operation when sealing film thereon, and uneven upper surface can influence the stacking up and down and the outward appearance of product.
The utility model content: the purpose of this utility model provides a kind of enclosuring structure that seals the smooth improved cup-shaped receptacle of upper surface.
The purpose of this utility model is achieved in that a kind of enclosuring structure of improved cup-shaped receptacle, comprise cup, rim of a cup flange, infrabasal plate, seal film and be arranged on the through hole that matches with rim of a cup flange bottom cup shape in the infrabasal plate middle part, wherein the periphery along through hole is provided with an annular groove on the upper surface of infrabasal plate; The shape of annular groove matches with the shape of rim of a cup flange.
Specialize in the annular groove of placing the rim of a cup flange owing on the upper surface of the infrabasal plate on the utility model, be provided with one, so when cup and infrabasal plate assemble, the rim of a cup flange places among the annular groove, and the upper surface of the upper surface of rim of a cup flange and infrabasal plate is concordant, thereby provide a smooth stickup face for sealing film, it is easier that film is sealed in feasible stickup; And the smooth upper surface the utility model of being more convenient for is stacked up and down each other, and attractive in appearance.

Among the figure: 1-content 4-seals film 7-infrabasal plate
2-cup 5-seals film pulling-on piece 8-annular groove
3-rim of a cup flange 6-infrabasal plate handle
The specific embodiment: a kind of enclosuring structure of improved cup-shaped receptacle, comprise cup 2, rim of a cup flange 3, infrabasal plate 7, seal film 4 and be arranged on the through hole that matches with rim of a cup flange 3 bottom cups 2 shapes in infrabasal plate 7 middle parts, wherein the periphery along through hole is provided with an annular groove 8 on the upper surface of infrabasal plate 7; The shape of annular groove 8 matches with the shape of rim of a cup flange 3, and promptly when cup 2 and infrabasal plate 7 were assembled together, rim of a cup flange 3 just in time was seated among the annular groove 8.
Theoretically, the height of the groove depth of annular groove 8 and rim of a cup flange 3 should cooperatively interact, promptly equate, when cup 2 and infrabasal plate 7 are assembled together, the upper surface of the upper surface of rim of a cup flange 3 and infrabasal plate 7 is concordant mutually, make and seal film 4 and can simultaneously form a bond area respectively with the upper surface of rim of a cup flange 3 and the upper surface of infrabasal plate 7, wherein sealing bond area formed between film 4 and the rim of a cup flange 3 is the sealing surface of an annular, its role is to prevent that the content 1 of splendid attire in the cup 2 from leaking; And the effect of sealing the bond area that forms between the upper surface of film 4 and infrabasal plate 7 is to improve the bind strength that seals film 4, and it can be ring seal, also can be non-ring seal.
But the cup 2 that rolls for cardboard, the height of its rim of a cup flange 3 is difficult to be made equally, so, the height that is slightly less than rim of a cup flange 3 that the groove depth of annular groove 8 can be done, like this, when sealing film 4 when overlaying on the upper surface of rim of a cup flange 3 and infrabasal plate 7, the deformability that can utilize rim of a cup flange 3 is pressed into the upper surface of rim of a cup flange 3 concordant mutually with the upper surface of infrabasal plate 7 and pastes, thus guarantee to seal film 4 can and the upper surface of rim of a cup flange 3 between form the bond area of a ring seal.
In addition, in order to take off when sealing film 4, infrabasal plate 7 and cup 2 can not broken away from, the outside dimension that is slightly less than rim of a cup flange 3 that the size suitable for reading of the annular groove 8 on the infrabasal plate 7 can be done, thereby rim of a cup flange 3 can be buckled among the annular groove 8 on the infrabasal plate 7, thereby can freely not separate.
Encapsulation process of the present utility model is as follows, at first is enclosed within infrabasal plate 7 on the cup 3 of rim of a cup flange 3 bottoms by the through hole on it; The content 1 of in cup 2, packing into then; To seal film 4 usefulness adhesive agents or hot melt adhesion again gets final product on the upper surface of rim of a cup flange 3 and infrabasal plate 7.
Opening process of the present utility model is as follows, after holding infrabasal plate handle 6 respectively and seal film pulling-on piece 5 with two hands, firmly one tears and gets final product.
