CN2363556Y - Impact-resistant compression-resisting elastic nest cap - Google Patents

Abstract

The utility model relates to an impact-resistant compression-resistant elastic sleeve cover, which comprises an external ring of a sleeve cover and an internal ring of a sleeve cover; the internal side on the internal ring of a sleeve cover is provided with a plurality of reinforcing ribs which are perpendicular to the top surface of the sleeve cover; the bottom edge of the internal ring of a sleeve cover is provided with an opening, and a plurality of resistance ribs are arranged between the internal ring and the external ring of the sleeve cover. The utility model has the advantages of simple structure and obvious cracking effects of the compression-resistant sleeve cover. Even though when the shaping is conducted, larger tolerance can not generate too large influence on elasticity of the sleeve cover, and a damaged phenomena of the sleeve cover of the product can be reduced in the storage and transportation process.

Description

Protecting against shock, anti-pressurized elasticity upper shield

The utility model be about a kind of bottle of placing cosmetics and hair care articles, jar the protecting against shock, the elasticity upper shield of anti-pressurized of aerosol jar of bottleneck upper shield, particularly a kind of mousse product.

The aerosol bottle of more existing cosmetics and hair care articles, jar upper shield, for example the upper shield of mousse series products jar in transportation as be inverted, fall with pressurized after the stressed outside expansion of upper shield (as Fig. 1) and as easy as rolling off a log generation is ftractureed or fragmentation.The locking form of this class upper shield is circumference locking in addition, and often because the moulding tolerance of product, upper shield can produce that tension inconvenience is opened or loose excessively during use, and causes the time spent to pick up bad phenomenon such as the upper shield Bottle ﹠ Can drops voluntarily.

The purpose of this utility model is exactly in order to solve the problem that the existing product structure exists, to design the elasticity upper shield of a kind of protecting against shock, anti-pressurized.

Formation of the present utility model comprises upper shield outer ring and upper shield inner ring, and there are several reinforcements perpendicular to the cover hd top face inboard of upper shield inner ring, on the upper shield inner ring root edge opening is arranged, and between the inner ring of upper shield and outer ring several resistance muscle is arranged.

The utility model has the advantages that simple in structure, anti-pressurized upper shield cracking effect is obvious, structure of the present utility model tolerance when moulding is big can not to produce too much influence to the degree of tightness of upper shield yet even use, and reduces the damage phenomenon of product upper shield in the storage and transport process greatly yet.

Fig. 1 is the unfavorable condition schematic diagram that produces behind the structure of existing moss tank upper shield and the pressurized thereof;

Fig. 2 is the cut-away view of the utility model structure;

Fig. 3, the 4th, the stressed back of the utility model upper shield situation schematic diagram.

Further specify embodiment of the present utility model below in conjunction with accompanying drawing.

The utility model is injection moulding all-in-one-piece upper shield outer ring 1 and upper shield inner ring 3, be provided with 2～5 reinforcements 4 in the inboard of upper shield inner ring 3, make the vertical force (as Fig. 3) that product is inverted, is fallen or the expansive force of the circumferencial direction of pressured state lower sleeve cover is changed into perpendicular to the cover hd top face prevent the upper shield cracking perpendicular to the cover hd top face; On upper shield inner ring 3 root edges opening 5 is arranged, the degree of depth of this opening must be greater than the height of tegmentum bottle (jar) mouth 6,2～5 resistance muscle 2 are arranged between upper shield inner ring 3 and upper shield outer ring 1, this resistance muscle 2 connects the outside of upper shield inner ring 3 and the inwall of upper shield outer ring 1, upper shield is pressed into bottle (jar) mouthful 6 o'clock inner rings 3 and can produces lateral deformation during use, make upper shield can slip into or pull away bottle (jar) mouth 6 smoothly, the resistance muscle of side then passes to 3 one desirable forces of periphery of inner ring with the spring action that deformability played of upper shield outer ring 1, can obtain by the size of adjustment cornerite and the wall thickness of upper shield outer ring 1 as for required elastic strength.

Claims (2)

1. the elasticity upper shield of a protecting against shock, anti-pressurized, comprise upper shield outer ring and upper shield inner ring, there are several reinforcements perpendicular to the cover hd top face inboard that it is characterized in that the upper shield inner ring, on the upper shield inner ring root edge opening is arranged, and between the inner ring of upper shield and outer ring several resistance muscle is arranged.

2. the elasticity upper shield of the anti-pressurized of protecting against shock according to claim 1, it is characterized in that the opening degree of depth on the upper shield inner ring root edge greater than the height of tegmentum bottle (jar) mouthful, the upper shield inner ring is connected the inwall of the outside and the outer ring of upper shield inner ring with the resistance muscle between the outer ring.
