Abstract

The utility model discloses an eraser anti-sticking sleeve, which comprises an elastic bag and an elastic eraser ring, wherein the elastic bag is a cylindrical elastic container, an opening is arranged on the front end of the elastic bag, the elastic eraser ring is arranged on the opening, the elastic eraser ring is an elastic retraction ring, and the opening of the elastic bag can be retracted and sealed when the elastic retraction ring retracts. The eraser anti-sticking sleeve can keep an eraser clean, also can prevent the eraser and other plastic products from being adhered with each other, and is cabinet in volume and flexible to use.

Description

The antiseized cover of rubber

Technical field

The utility model relates to a kind of schooling apparatus, particularly relates to the antiseized cover of a kind of rubber.

Background technology

Have many students all to like using the pen bag to place stationery, but rubber is placed in the pen bag, of long duration just easily and other plastic products stick together, want separately just cumbersome; And the rubber of one deck paper is wrapped in those outsides, and the Bao Detaisong rubber just drops out easily, and Bao Detai tightly just is not easy to take out.

Summary of the invention

In order to address the above problem, the purpose of this utility model is to provide a kind of rubber antiseized cover.

In order to achieve the above object, the antiseized cover of rubber that provides of the utility model comprises: elastomeric bladder and flexible rubber ring; Wherein: elastomeric bladder is the elastic container of a cylindrical shape, its front opening, and opening part is provided with flexible rubber ring; Flexible rubber ring is an elastic shrinkage ring, and it can tighten sealing with the opening of elastomeric bladder when shrinking.

The size of described elastomeric bladder is as the criterion with the size of holding a complete rubber.

The rubber that the utility model provides is antiseized to be enclosed within when using, and earlier flexible rubber ring is strutted, and rubber is pushed among the elastomeric bladder, after rubber all enters into elastomeric bladder inside, flexible rubber ring shrinks, and the opening of elastomeric bladder is tightened, thereby the rubber and the external world are separated; When needs use rubber, the opening of rubber from elastomeric bladder outwards pushed up, thereby the end that flexible rubber ring expansion this moment makes rubber from the opening part of elastomeric bladder to exposing outside, at this moment the contractility of flexible rubber ring can be fixed rubber, so just can use the rubber that is exposed at the elastomeric bladder outside to be coated with wrongly written character; After finishing using, rubber is back among the elastomeric bladder again.

The antiseized cover of the rubber that the utility model provides can either keep the cleaning of rubber, can avoid rubber and other plastic products inter-adhesive again, and volume is small and exquisite, uses flexibly.

Description of drawings

Fig. 1 forms schematic diagram for the antiseized cover of rubber that the utility model provides.

Label among Fig. 1: 1 elastomeric bladder, 2 flexible rubber rings, 3 rubbers.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the antiseized cover of rubber that the utility model provides is described in detail.

As shown in Figure 1, the antiseized cover of rubber that provides of the utility model comprises: elastomeric bladder 1 and flexible rubber ring 2; Wherein: elastomeric bladder 1 is the elastic container of a cylindrical shape, and its front opening, opening part are provided with flexible rubber ring 2; Flexible rubber ring 2 is an elastic shrinkage ring, and it can tighten sealing with the opening of elastomeric bladder 1 when shrinking.

The size of described elastomeric bladder 1 is as the criterion with the size of holding a complete rubber.

The rubber that the utility model provides is antiseized to be enclosed within when using, and earlier flexible rubber ring 2 is strutted, and rubber 3 is pushed among the elastomeric bladder 1, after rubber 3 all enters into elastomeric bladder 1 inside, flexible rubber ring 2 shrinks, and the opening of elastomeric bladder 1 is tightened, thereby the rubber 3 and the external world are separated; When needs use rubber 3, the opening of rubber 3 from elastomeric bladder 1 outwards pushed up, thereby the end that flexible rubber ring 2 expansion this moment makes rubber 3 from the opening part of elastomeric bladder 1 to exposing outside, at this moment the contractility of flexible rubber ring 2 can be fixed rubber 3, so just can use the rubber 3 that is exposed at elastomeric bladder 1 outside to be coated with wrongly written character; After finishing using, rubber 3 is back among the elastomeric bladder 1 again.

Claims

1. antiseized cover of rubber, it is characterized in that: the antiseized cover of described rubber comprises: elastomeric bladder (1) and flexible rubber ring (2); Wherein: elastomeric bladder (1) is the elastic container of a cylindrical shape, and its front opening, opening part are provided with flexible rubber ring (2); Flexible rubber ring (2) is an elastic shrinkage ring.

2. the antiseized cover of rubber according to claim 1 is characterized in that: the size of described elastomeric bladder (1) is as the criterion with the size of holding a complete rubber.
