Abstract

The contact part (122) of the circumferential wall (12) of the wooden cork (1) with a bottle opening (21) is set into a concave arc-shaped curved surface structure. As the bottle opening (21) is a protruded arc-shaped curved surface, the contact of the wooden cork (1) with the bottle opening (21) is surface contact (linear contact on the longitudinal section), the contact area of the wooden cork (1) with the bottle opening (21) is increased, and the wooden cork (1) is better matched with the bottle opening (21). Thus, the heat insulating effect and the covering tightness are improved.

Description

The glass inner bag vacuum flask stopper of all cornice imploded arcs shape curved surfaces

Technical field

The utility model relates to daily living article, relates in particular to glass inner bag vacuum flask stopper.

Background technology

The Chinese utility application that application number is 200920078817.5, name is called the stopper of being with draw ring, although increased a draw ring, but the stopper of this design part has then embodied the basic structure of traditional glass inner bag vacuum flask stopper, and it comprises top, bottom and perisporium.

Stopper is generally truncated cone shape, and its perisporium is curve slope (on longitudinal sectional drawing, its perisporium is a straight line), and stopper covers into bottleneck during use.

The stopper of this traditional structure, its deficiency are that stopper is line contact (being the some contact on profilograph) with contacting of bottleneck, and contact area is less, thereby has influence on heat insulation effect and the tight degree of lid.

Summary of the invention

Technical problem to be solved in the utility model is:

Increase the contact area of glass inner bag vacuum flask stopper (1) and glass inner bag bottleneck (21), thereby improve heat insulation effect and the tight degree of lid.

The technical scheme that its technical problem that solves the utility model adopts is:

The perisporium (12) of stopper (1) is set to indent arc curved-surface structure with the position (122) that glass inner bag bottleneck (21) contacts.

Because bottleneck (21) is the arc-shaped curved surface of evagination, the perisporium (12) of stopper is set to indent arc curved-surface structure with the position (122) that bottleneck (21) contacts, will make that stopper (1) and contacting of bottleneck (21) are face contact (being the line contact) on profilograph, thereby increase the contact area of stopper (1) and bottleneck (21).

Usefulness of the present utility model is: increased the contact area of stopper and bottleneck, made stopper match with bottleneck better, thereby improved heat insulation effect and the tight degree of lid.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a vertical section of the present utility model schematic diagram.

Fig. 2 is a user mode of the present utility model vertical section schematic diagram.

Among the figure: 1, stopper, 11, the stopper top, 12, the stopper perisporium, 122, the stopper perisporium is with the position of bottleneck contact, 13, the stopper bottom, 2, glass inner bag, 21, bottleneck

The specific embodiment

Referring to Fig. 1, stopper (1) is processed by natural cork, have top (11), bottom (13) and perisporium (12), perisporium (12) is gone up the arc-shaped curved surface (on profilograph, the arc-shaped curved surface of this indent is shown as an indent arc curve) that indent is processed at the position (122) of preparing to contact with bottleneck (21).

Referring to Fig. 2, during use stopper (1) lid is gone into the bottleneck (21) of glass inner bag (2), the indent arc-shaped curved surface (122) of stopper perisporium is with closely contact of bottleneck (21), because bottleneck (21) is the arc-shaped curved surface of evagination, formation face contact (on profilograph, being the line contact), increased the contact area of stopper (1), just increased the sealing area of stopper (1), thereby improved heat insulation effect and the tight degree of lid glass inner bag (2) with bottleneck (21).

Claims

1. the glass inner bag vacuum flask stopper (1) of all cornice imploded arcs shape curved surfaces, it comprises top (11), bottom (13) and perisporium (12), it is characterized in that: this perisporium (12) is an indent arc curved-surface structure with the position (122) of bottleneck (21) contact.
