Description

The lid driving fit structure of container

Technical field

The utility model relates to a kind of container, relates in particular to a kind of lid driving fit structure of container.

Background technology

Many on the market liquid form products must be encapsulated airtight by the container with lid, and the kenel of described lid, according to the use kenel difference of product different designs is arranged, for example general shampoo, liquid laundry detergent etc. can adopt the lid design of reducing shape, paint kettle then is to adopt big ringent lid design, and the big opening shape of this kind cover body structure, since big with the combined area of container ladle body opening, so often have the not enough problem of adaptation between container ladle body and the lid.

With appreciiable plastics system paint kettle structure on the market at present, there is the producer to adopt to be provided with multiple tracks engaging position that the state of covering of lid and container ladle body is reached comparatively firmly to be difficult for the purpose that gets loose, but state in realization in the process that covers, utility model contriver finds that there are the following problems at least in the prior art: even adopt multiple tracks engaging position is set, but for the adaptation of combination, often do not obtain effective solution because of increasing of position of engaging, when container is toppled over, liquid wherein often still can cover the outside seepage in position from its lid and container ladle body, causes the problem that can't guarantee container air-tight state and packaging quality.

The utility model content

Embodiment of the present utility model provides a kind of lid driving fit structure of container, can significantly improve the adaptation of lid and cylindrical shell combination, the problem of fluid seepage wherein when effectively solving container and toppling over.

For achieving the above object, embodiment of the present utility model adopts following technical scheme:

A kind of lid driving fit structure of container comprises: an outer shroud frame, and to be located at this lid and to cover the face periphery, this outer shroud frame inboard is provided with the engagement section; One inner ring frame is located at this lid and is covered face and be positioned at this outer shroud frame clear width place, and this inner ring frame has inside and outside side, and this medial surface is set as the taper kenel; One intercalation groove is formed between this inner and outer rings frame; One driving fit edge portion is formed at this intercalation groove indent this side of the corresponding described inner ring frame in end place to the greatest extent that makes progress; The one protruding frame that connects, be located at the open end of cylindrical shell can corresponding insert group in this intercalation groove, and constitute this protruding frame inwall and inner ring frame lateral surface state that leans that connects; One driving fit butting section is formed at this protruding frame elongated end that connects and can fastens driving fit mutually with this driving fit edge portion; One steady ring frame is located at the cartridge openings end outside, and this steady ring frame is provided with the location of can matching with this set engagement section of outer shroud frame, engaging location division.

Product of the present utility model, described driving fit butting section kenel can with the matching design of the corresponding driving fit of this driving fit edge portion's kenel, can make in conjunction with more closely, consolidation; The medial surface of inner ring frame is set as upwards the taper kenel design of introversion gradually, can promote this inner ring frame against the protruding toughness that connects frame, makes the two mated condition more firm; This driving fit edge portion has the feature of a convex curved part, promotes the steady status that taper cooperates between this driving fit edge portion and the driving fit butting section.The contrast prior art, the lid of container and the combination between the cylindrical shell reach closed state, and in conjunction with consolidation more, firm, liquid is difficult for leakage.

The specific embodiment

Be described in detail below in conjunction with the lid driving fit structure of accompanying drawing the utility model embodiment container.

See also Fig. 1, Fig. 2, Fig. 3, Fig. 4, preferred embodiment for the lid driving fit structure of utility model container, cylindrical shell 10 open ends 11 that described lid driving fit structure is located at a container A cover face 21 corresponding cooperation places with a lid 20, and this lid driving fit structure comprises following formation:

One outer shroud frame 30 is located at the periphery that this lid 20 covers face 21 and is downward extension shape, and the inboard of this outer shroud frame 30 is provided with engagement section 31;

One inner ring frame 40, be located at the clear width place that this lid 20 covers face 21 and be positioned at this outer shroud frame 30 and be downward extension shape, this inner ring frame 40 has medial surface 41 and lateral surface 42, and this medial surface 41 is set as upwards the taper kenel of introversion gradually, adopt the angle of inclination design of described medial surface 41, make the upper end root thickness of inner ring frame 40 thicken reinforcement, and then promote this inner ring frame 40, make its mated condition more firm against the protruding toughness that connects frame 70;

One intercalation groove 50 is formed at and is the annulus kenel of indent upwards between this outer shroud frame 30 and the inner ring frame 40;

One driving fit edge portion 61 is formed at upwards indent this side of the corresponding described inner ring frame 40 in end place to the greatest extent of this intercalation groove 50;

The one protruding frame 70 that connects, the open end 11 of being located at cylindrical shell 10 are and extend upward shape, this is protruding connect frame 70 can corresponding insert group in this intercalation groove 50, and the lateral surface that constitutes this protruding inwall 71 that connects frame 70 and the inner ring frame state that leans;

One driving fit butting section 80 is formed at this protruding end that extends upward that connects frame 70, and the kenel of this driving fit butting section 80 can correspondingly with the kenel of this driving fit edge portion 61 fasten reaches firm closed state;

One steady ring frame 90, open end 11 outsides of being located at cylindrical shell 10 are downward extension state, and these steady ring frame 90 lateral surfaces are provided with engaging location division 91 and can cooperatively interact to reach with these outer shroud frame 30 set engagement sections 31 and engage positioning action.

Wherein, detailed shown in the 3rd figure, the upright walls that the inwall 71 that this is protruding to connect frame 70 and the lateral surface 42 of inner ring frame 40 can be vertical angle leans and cooperates kenel.Again, as the 6th figure the disclosed embodiments, the oblique wall that the inwall 71B that this is protruding to connect frame 70 and the lateral surface 42B of inner ring frame 40 can be the angle of inclination leans and cooperates kenel.

Wherein, this cylindrical shell 10 protruding connects frame 70 outer walls and outer shroud frame 30 inwalls of lid 20 and can be provided with at least one
