Description

The closure member that is used for container

Technical field

The utility model relates to a kind of closure member that is used for container, and it is vertically compact.

Background technology

As everyone knows, the closure member (particularly being installed in the closure member on the bottle that precious liquid is housed) that is used for container must be able to indicate and open first so that the clear indication that provides container also not to be opened to the buyer.

Because removable inner member was in primary importance and is in the second place after opening first before opening first, thereby some closure members can change its outward appearance basically.

The WO2005/021400 that belongs to GUALA CLOSURES S.P.A company discloses the example of these closure members.Yet the closure member of its description requires container neck to have the threaded portion engagement male thread portion thereon of lid.

Male thread portion needs special design, owing to can not obtain to cooperate according to the manufacturing and/or the assembling of the structure member of other closure members, thereby cause the expensive of closure member.

On the other hand, in the known closure member (the disclosed closure member of EP1511677 that for example belongs to GUALA CLOSURESPATENTS BV company), developed the closure member that is easy to manufacture and assemble, but because the closure member portion size that the outward appearance change has influence on is less, so tamper evident system (just being used to indicate the system that opens first) is simple relatively.

The utility model content

Consider described prior art, the technical problems to be solved in the utility model is: a kind of optics closure member is provided, and promptly it has the big part by the appearance change influence, and it is modular and simplicity of design.

According to the utility model, realize this purpose by a kind of closure member that is used for container.This closure member comprises: dumping mouth, and it comprises the external screw-thread part; Anchor fitting is used for described dumping mouth is fixed to the opening of described container; The negative thread lid is used for and described dumping mouth engagement, it is characterized in that described lid comprises: first element and second element, but be secured together by at least one breaking portion; But be used for brokenly encircling the device of described at least one breaking portion; But described breaking plant is provided in first and destroys described breaking portion in the opening procedure.Adopt this closure member, do not require that container neck has the threaded portion engagement male thread portion thereon of lid, thereby reduced the productive costs of closure member, and the closure member portion size that the appearance change of this closure member has influence on is bigger, thereby tamper evident system is more reliable.

Description of drawings

From the description of the possible embodiments that provides by the indefiniteness example below with reference to accompanying drawing, it is clear that feature of the present utility model and advantage will become:

The viewgraph of cross-section of the utility model preferred embodiment before Fig. 1 shows and opens first;

Fig. 2 shows the viewgraph of cross-section of closure member after opening first according to Fig. 1;

Fig. 3 and 4 shows the viewgraph of cross-section according to the displaceable element of the embodiment of Fig. 1 respectively from top and front.

The specific embodiment

With reference to the accompanying drawings, closure member 1 comprises dumping mouth 2 and lid 3, and dumping mouth 2 is fixed on the container 100 (for example bottle), and can make the fluid that holds flow out, and lid 3 can be fixed on the dumping mouth 2, and can prevent that liquid from flowing out in container.

Dumping mouth 2 has male thread portion 6 and is fixed to the oral area of container 100 by securing device 7; Lid 3 has the male thread portion 6 ingear threaded portions 8 that are used for dumping mouth 2, but and comprise first element 9 and second element 10 that is fixed together by at least one breaking portion, but and the breaking plant 11 that is designed to destroy breaking portion.

But broken loop device 11 is set to destroy breaking portion in the opening procedure first of container.

Advantageously, but the ruptured bridgeware 12 of breaking portion by for example radial direction form, as shown in Figure 3.

The bridgeware 12 that can rupture can have radially outward tapered cross-sectional plane, makes the minimum drag cross-sectional plane be positioned near first element 9 and prevent to form undesirable burr in bridgeware 12 fracture backs.

Second element 10 can comprise little sawtooth 28 on the one side or the both sides of each bridgeware 12, and it for example is formed within second element 10 self and helps near fracture bridgeware 12 bridgeware 12 is connected to point on first element 9.

First and second elements 9,10 can be two linings, and for example the lower end 13 of first element 9 is connected to the upper end 14 of second element 10.

In addition, first and second elements 9,10 can be taper shape slightly and/or the wall with axial clearance, and it is divided into one or

more section

15,16 with them.

Advantageously, the section 15 of first element 9 connects together by the attaching parts 4 that is designed to rupture; Opposite, but the section 16 of second element 10 is separated from each other and the attaching parts 4 by first element 9 only keeps together by breaking portion, as Fig. 3 and 4 findings.

Advantageously, second element, 10 to the first elements 9 are little, and promptly second element 10 can pass first element 9.In other words, the minimum inside diameter of first element 9 is greater than the maximum outside diameter of second element 10.

As shown in Figure 3, first and second elements 9,10 can be divided into a plurality of

sections

15,16, and they all have identical angular region, for example three sections.

Yet quantity of each

section

15,16 and/or angular region can be different.For example, can have two, four, five, six or

more section

15,16, all sections all have identical angular region or different angular regions.

In addition, even the section that is connected respectively among the figure together 15 and 16 has corresponding angular region, this feature neither be essential, and section 15 can have different angular regions with 16.

Still with reference to figure 3,, can see the ruptured bridgeware 12 of three same intervals for each

section

15,16; This quantity can be different, can be one, two or four bridgewares 12 for each

section

15,16 for example.

Normally, section 16 the angular region of second element 10 is preferably less than 200 °, so that can shift out from the neck of container 100 opening back segment 16 first.

Second element 10 also can comprise the centring adjustment sheet, in it points to and help to guarantee that container 100 and closure member 1 are coaxial.

Second element 10 comprises and is used for preventing the device that vertically moves up at opening procedure first.These devices (for example comprising sheet 17) and form the surface of a part of protrusion on container 100 openings or the element (securing device 7 as illustrated in fig. 1 and 2) that is arranged on container 100 tops in abutting connection with interlocking.

Because suitable enhancing connecting panel 5, the resistance of sheet 17 are much larger than the resistance of breaking portion, therefore, even may attempt removing lid 3 from dumping mouth 2, but breaking portion also can rupture before sheet 17.

Lid 3 comprises annular basically outer body 18 and also is the inside body 19 of annular basically; Outer body 18 and inside body 19 limit recess 20 jointly.Advantageously, outside and inside

body

18,19 and recess 20 are essentially cylindrical.

Recess 20 at base seal, and is received first element 9 (can find out) opening the back first by transverse wall 21 from the contrast of Fig. 1 and Fig. 2.

First element 9 is therefore greater than inside body 19, because first element 9 can cross around inside body 19, and second element 10 is less than inside body 19; In other words, under the situation of not considering any tapering, the cross-sectional plane of second element is less than the cross-sectional plane of inside body 19.

As seen in Figure 1, inside body 19 can contact with second element 10 basically.

Inside body 19 comprises breaking plant 11 in the top.These breaking plants can comprise cutting tip, and this cutting tip is for example aimed at the inside face of first element 9 basically.The tip can be a form continuous or section.

Advantageously, the lower end of the lower end of inside body 19, outer body 18 and transverse wall 21 substantial alignment.Seen in Fig. 1 and 2, in the inside that advantageously is the outer body 18 of hollow, lid 3 comprises the central body 22 with threaded portion 8.Central body 22 and outer body 18 adopt known method to link together, for example by ultrasonic welding.

Central body 22 comprises the stave 24 of annular basically, and it helps to limit the top of recess 20.

Stave 24 can for example be limited in rotation and translation by the tooth bar 25 with sealed lip 26 about advantageously comprising the inside lower cover 27 of threaded portion 8.

As seen in Figure 1, inside body 19 and stave 24 limit the complete basically recess 20 except little space, but breaking portion extends through this little space between upper element 9 and lower element 10.

Like this, be difficult to operation upper part element 9 especially, even after opening first.

In a preferred embodiment, the longitudinal length of second element 10 is slightly larger than the longitudinal length of inside body 19; But the longitudinal length of outer body 18 is substantially the same or be slightly larger than the longitudinal length of first and second elements 9,10 that connect together by breaking portion.

But upper element 9 can advantageously comprise end portion 23 between its lower end 13 and breaking portion, even this end portion 23 was also inserted recess 20 inside before opening first.

Easily, closure member 1 can comprise and prevent device for filling once more, and boiler check valve for example is as ball valve.

These prevent that once more device for filling can remain on the opening of container 100 by the identical anchor fitting 7 that keeps dumping mouth 2.Advantageously, anchor fitting 7 and dumping mouth 2 metal sheet integrally formed or by for example distortion in rolling forms.

With reference to the accompanying drawings, now the operation of opening closure member 1 will be described schematically.

Begin with the structure before opening first, as shown in Figure 1, the user applies moment of torsion on lid 3, makes its rotation.

Upwards promote lid 3 with the threaded portion 6 ingear threaded portions 8 of dumping mouth 2.

The breaking plant 11 that is formed on the inside body 19 is also upwards promoted by transverse wall 21, thereby but contacts with breaking portion.

The inner member 10 that directly is not fixed on the inside body 19 vertically keeps by sheet 17.

But the promotion breaking plant 11 that is further rotated of lid 3 leans against on the breaking portion: but because sheet 17 has the resistance greater than breaking portion, so but breaking portion fracture and lower element 10 leave upper element 9.

Then, upper element 9, leans against on the transverse wall 21 in the recess 20 because gravity drops into.

Along with the continuation rotation of lid 3, the section 16 of lid 3 and dumping mouth 2 jump out of meshs and lower element 10 drops on outside the protrusion 101 of container 100.

Selectively, if container 100 does not have protrusion 101, section 16 or whole second element 10 also can drop downwards.In this case, but second element, 10 favorable terrains become lining, so, drop along the neck of container 100, the evidence of further opening first can be provided, and not need the separate processes of element 10.

Advantageously, outer body 18 is made by the material of partially transparent at least, so that can see the structural change that upper element 10 drops and causes from the outside in recess 20.

Especially, outer body 18 can all be made by transparent material, and for example glass, polycarbonate or other amorphous polymers perhaps can comprise transparent part, and window for example perhaps allows to see the part of inner recess 20, for example hollow bulb; Outer body 18, upper element 9 and stave 24 form colored usually, so that just can find from the outside opening the change in location of upper back element 9 first, and by means of the autograph that after opening first, manifests and/or disappear.

As shown in Figure 1, upper element 9 covers whole core 24 basically, so that hide its color before opening first.

According to closure member 1 of the present utility model according to following assembling:

(a) at first together with forming dumping mouth 2 with dumping mouth 2 integrally formed parts;

(b) by anchor fitting 7 dumping mouth 2 is fixed on the container 100;

(c) lid 3 is installed.

Especially, step (a) can comprise the assembling of dumping mouth 2, and if desired, dumping mouth 2 is connected on the anchor fitting 7 that forms sheet metal, link to each other with lower cover 27, and if desired with prevent that filling system links to each other once more; In step (c) before, that can assemble lid 3 is not fixed to part on the dumping mouth 2, for example inserts upper and lower element 9,10, makes them lean against on the breaking plant 11 before central body 22 is fixed on the outer body 18; Then, step (c) can comprise that the

element

9,10,18 and 22 that will be assembled into together is inserted on the lower cover 27, so that longitudinal component 24 is fixed on the lower cover 27 in changeless basically mode on rotation and translation direction, thereby advantageously,, lid just make sheet 17 snap into engagement arrive their holding position as long as carrying out necessary motion.

Advantageously, but upper and lower element 9,10 is made for example HIPS (HTPS) or ABS together with the polymer that breaking portion can be all has low distortion when losing efficacy.

It is evident that in order to satisfy chance and particular demands, those skilled in the art can make various modifications and variations to said structure, all such modifications and variation are included in the protection domain of the utility model claims.
