Description

The stationary member of distributing box

Technical field

The present invention relates to a kind of mobile dispenser, this distributing box comprises an allocation member, as a pump or valve, a container and a stationary member that allocation member is fixed on container neck that forms neck.The invention still further relates to a kind of such stationary member.Stationary member comprises a shirt rim, and the shirt rim forms an inwall that cooperates with container neck.

Background technology

Use this distributing box of this stationary member usually to be used for medicine, cosmetics or perfume aspect, be used for the distributing fluids product.

People understand polytype stationary member in the prior art, usually they are called set collar.The general shirt rim that forms a downward extension of this ring, a footing that is used for forming with container neck cooperates.This usually is called the reinforcing on " lip limit " or the part of thickening is outwards given prominence to, and forms a following convex shoulder.The shirt rim of annular comprises following continuous striped or some dop of convex shoulder that is used to be stuck in lip limit shape.The shirt rim can be continuous, perhaps on its height breach is arranged, so that form some pawls, the end of pawl forms dop.When there is breach the shirt rim and form some pawls and dop, generally be provided with a cuff, cuff is worn on the shirt rim and covers the shirt rim, so that dop is blocked in below the convex shoulder on lip limit.In the shirt rim continuously and form under the continuous situation that snaps in intra-striate, do not need cuff, and cuff has only Aesthetic Function in this case.

Under the continuous or fatiscent two kinds of situations in shirt rim, snap in striped or dop and cooperate with the convex shoulder on lip limit.The outer support section of the cylindricality on skirt section and lip limit is without any to be fixed as the mutual action of purpose.

But, snap in striped or dop is in place below the convex shoulder on lip limit owing to must firmly make, this have breach or unsplit shirt rim to be easy to distortion.Snapping under the situation that pawl has dop, during installation, this plastic deformation takes place in the shirt rim under the effect of cuff.Being equipped with under the situation of continuous shirt rim that an inside snaps in striped continuously, can see the distortion of shirt rim sometimes from the outside.

Summary of the invention

The objective of the invention is to overcome the above-mentioned shortcoming of prior art, form a kind of stationary member, any dimensional deformation is not born in its shirt rim, and can realize a kind ofly without cuff the shirt rim being blocked in the effectively fixing of container neck.

For this reason, the present invention proposes, and described inwall has at least two vertical fins that extend on the height of shirt rim, and described fin cooperates with the outside of neck by plastic deformation.

With below the convex shoulder that is positioned at the lip limit and only cooperate with this convex shoulder snap in striped or dop is opposite, fin of the present invention extends on the height on lip limit, and extends to below the lip limit, makes shirt rim and neck realize contacting on a big chunk of shirt rim height.

According to an embodiment, before stationary member was installed in neck, the internal diameter shape of fin was less than the external diameter of neck, and after the installation, fin on the outer support section of neck plastic deformation takes place.Because fin longitudinal extension and separated from each other, plastic deformation can take place in comparalive ease on the lip limit of neck, and don't the outer wall of shirt rim is damaged or distortion.

According to another embodiment, footing or lip limit keep fluctuating by at least one and form, and fin is deep in these projectioies by plastic deformation.

In addition, described at least one fluctuating extend in footing around.

For example, fluctuating can show as one or several circular trough for forming in the outer support section of cylindricality substantially on the lip limit.Certainly imagine the whole shape of the exterior contour of lip limit support section, so that improve the suspension of fin by plastic deformation.Therefore, for profile, must understand that it is meant any apparent condition of support portion outside the lip limit of the maintenance that can improve stationary member.

As modification, described at least one profile extension and is shaped as a vertical grooving on the height of footing, and the width of described profile is less than the width of fin, so that fin is remained in the described profile by plastic deformation.In this case, profile no longer is a circumferential, but vertical, passes the lip limit of neck.In addition, the width of profile begins to reduce from the upper end of neck.In the neck upper end, it is wide that profile cans be compared to fin most, therefore must be narrower than fin in the neck lower end.This helps fin on the one hand and enters in the groove, goes into effect by a fork on the other hand fin is remained in the groove.

According to another feature of the present invention, the shirt rim comprises a vertical inner groovy, after this groove radially is positioned at fin, and in the thickness of shirt rim, make fin can be in their grooves separately radial and outward deformation, and can not make the outer wall distortion of shirt rim.Inner groovy can make the convex rib deform, and does not influence the outer wall of shirt rim.Can be installed in a cuff on the shirt rim in advance like this.Garter spring can contact with the outer wall of shirt rim on the whole circumference of shirt rim, comprising the inner groovy place.Certainly, inner groovy is the groove that does not lead to the shirt rim outer wall, so the shirt rim can keep cylindrical fully.Groove is preferably opened, or leads to the lower end of shirt rim, and therefore being shaped as some lower ends from the shirt rim begins axially extended blind hole the wall thickness of shirt rim.In order to produce good distortion by the plasticity of fin, it is wide that groove cans be compared to fin most.

Can also imagine a kind of fatiscent shirt rim that forms some pawls, fin forms in pawl.In this case, stationary member comprises a cuff that covers the shirt rim to small part.Because fin is deformable, and the outer wall of shirt rim can not be out of shape, cuff can be installed in container neck at stationary member and be installed on the stationary member in the past.Therefore, stationary member and cuff can be used as the neck of a unified integral installation at container.

The present invention also aims to a stationary member, its shirt rim inwall forms some vertical fins, and these fins can contact with the outside of neck by plastic deformation.

The specific embodiment

At first explain first embodiment with reference to Fig. 1 a and 1b.Stationary member comprises an annular 2, is for example formed by plastic pouring, and forms a dump tank 21, is used for accepting an allocation member (not shown) by firmly snapping in, as a pump or valve.Reinforcing fin that can snap onto in the dump tank 21 of general formation on the health of valve or pump.The throw rod of valve or pump passes an opening 24 in the annular.The periphery of dump tank 21 is connected with a platform 22, and platform 22 is used for reclining with a packing seal 4 between platform 22 and container neck upper end and contacts.The periphery of platform 22 and a profile are that the shirt rim 20 of cylindricality is connected substantially.Extend downwards from platform 22 shirt rim 20, but also can extend upward shown in Fig. 1 b.The shirt rim cooperates with the neck 10 of container 1 in the part of its downward extension, and neck 10 also has the part 11 to the thickening or the reinforcing of outer lug, is commonly referred to the lip limit.The lip limit extends to the upper end of neck 10 always, forms a sealed core 14 here, and cushion 4 produces distortion on sealed core 14.Certain distance is extended on the lip limit downwards, forms a convex shoulder then, is used to connect the cylindrical section that recess diameter reduces.

According to the present invention, there is an inwall that has several fins 23 shirt rim 20, and fin 23 vertical extent are on the part or whole height of shirt rim 20.In the embodiment shown in Fig. 1 a and the 1b, the quantity of these fins 23 is 8, is evenly distributed on the interior week of shirt rim 20 inwalls.The extended height of fin 23 is greater than the height on lip limit 11.Can imagine that also the extended height that fin is equal to or slightly less than the embodiment of lip limit height.

According to the present invention, fin 23 limits the virtual cylindricality that the fin end points passes through, and the diameter of this virtual cylindricality is less than the external diameter on lip limit 11, in case make the shirt rim be installed in the neck 10 of container 1, plastic deformation just takes place in fin 23, and reclining basic is the outer support section on the lip limit 11 of cylindricality.In order to improve the maintenance of fin on the lip limit, fin can extend to below the convex shoulder on lip limit always, so that cooperate with this convex shoulder, this helps the shirt rim to be suspended on neck.Can also make the outer support section on lip limit 11 have a profile that can improve the fin suspension.Among Fig. 1, the profile of the outer support section on lip limit 11 has a circular groove 12, and circular groove 12 is placed extension outside lip limit all or part of.Several such profiles can also be set.Therefore, fin can be deep in these profiles by the plasticity extruding, and improves the suspension of shirt rim 20 on neck 10 thus.When lip limit 11 was provided with this profile or groove, fin did not need to extend to below the convex shoulder on lip limit always.In other words, opposite with the prior art of narrating above, the shirt rim does not cooperate with the convex shoulder on lip limit can realize that also annular is suspended on the neck.As long as it is just passable that the outer support portion of the moulding on lip limit makes the fin of shirt rim effectively remain on neck.Because fin is separately to distribute, and the direction that only enters neck in annular constitutes point-like and reinforces, so these fins can deform, and the outer wall of shirt rim does not deform thus.

It is pointed out that the cuff 3 that does not need shown in Fig. 1 b makes shirt rim 20 be suspended on neck, cuff 3 is used for being blocked under the convex shoulder on lip limit snapping in head in the stationary member of prior art.Here 3 of cuffs play a kind of aesthetic effect, and can just be installed in advance on the annular 2 before annular is installed in container neck.Because the plastic deformation of fin can not make the outer wall of shirt rim produce distortion, therefore in fact this is possible.Therefore, can save cuff 3 in some applications.

Explain the second embodiment of the present invention referring now to Fig. 2,3a, 3b.In this embodiment, annular 20 also has the fin 23 of some vertical extent on the part height of shirt rim.Embodiment is the same with fwd, and these fins 23 cooperate with the lip limit 11 of container neck 10.According to the present invention, can in lip limit 11, realize several vertical groovings.These profiles or grooving can extend upward from the bottom on lip limit, and the lip limit is interrupted herein, but grooving also can begin from the upper end on lip limit only to extend at the part height, make the lower end on lip limit keep motionless.In for the used embodiment of expression the present invention, grooving 15 extends in the both sides on lip limit.See that from Fig. 3 a there are two such groovings on lip limit 11.Certainly, plural this grooving can be set, for example be evenly distributed on around the neck.According to the present invention, the quantity of the fin 23 that forms on the shirt rim 20 also is two, can be inserted in the grooving 15 on lip limit.In addition, the width of the grooving on lip limit or profile 15 makes fin 23 that plastic deformation take place less than the width of fin 23, and the edge of the grooving 15 that reclines.The width of grooving 15 preferably begins to reduce from the upper end of neck, makes grooving at the width of the neck upper end width greater than fin, and grooving is at the width of the lower end width less than fin 23.Therefore, fin 23 can firmly be inserted in the grooving 15.As what can see in Fig. 3 b, the sloping edge of grooving 15 forms a fork-shaped profile, for example is positioned at the lower end of grooving 15.Can also imagine and to have the fork-shaped profile that one or several forms on the edge beyond the grooving lower end.Fin radial deformation in the embodiment of Fig. 1 a and 1b, and the edge of the distortion of fin and grooving 15 is tangent here.So vertical slot 15 is arranged, and the suspension of shirt rim 30 is by vertical barrier, and is also rotatable simultaneously.In fact, because the fork-shaped profile 16 that exists lip limit 11 to form, stationary member can not take out from neck.Therefore guarantee the firm and irreversible function of annular at neck.

Can not make the outer wall of shirt rim 20 produce any distortion since it is pointed out that the distortion of fin, therefore also can be installed in neck in annular installed cuff 3 in the past in advance.

The 3rd embodiment shown in Fig. 4,5 is the modification of first embodiment of Fig. 1 a and 1b.Shirt rim 20 has some to extend in vertical inner groovy 26 on the height of shirt rim here.

These grooves 26 are in-to-ins, and are because they neither lead to inwall 202, also obstructed to outer wall 201.20 lower end 203 extends upward from the shirt rim for they, therefore be shaped as some lead to lower end, shirt rim 203 and at shirt rim wall thickness axis to upwardly extending blind hole.For example these grooves can be realized by a hammer drill that is deep into the model from the lower end, shirt rim.

As can seeing that groove 26 separate with outer wall 201 by some wall sections 28 from Fig. 5, and separate with inwall 202 by other wall section 27, vertical interior fin 23 forms on wall section 27.Therefore, a groove 26 is relevant with a fin 23 all the time, and before fin radially is positioned at groove.In other words, if from the center of stationary member, after groove 26 is positioned at fin 23 just, make fin can be in groove radial and outward deformation, particularly when they are installed in container neck.Fin 23 be out of shape in the process, have only wall section 27 to deform, and wall section 28 is not born any distortion.Therefore, when annular was installed in container neck, the outer wall 201 of shirt rim 20 did not deform.Therefore can before annular being installed to container neck, be installed in cuff 3 on the annular.As seeing from Fig. 5, the cuff 3 that has outer wall 32 and inwall 33 and health and be substantially cylindricality can contact with the outer wall 201 of shirt rim on its whole circumference.As shown in Figure 4, stationary member can be installed in and have the neck that is contained in the cuff 3 on the annular 2.

In addition, groove is wideer than fin.

For example, fin 23 can be in inside radial deformation in the groove 26 by the wall 13 at convex shoulder 11 profile places under neck 10 is equivalent to thicken.It is pointed out that vertical fin 23 that these extend on the whole thickness of shirt rim, just realize fixing on the neck that can change at a kind of height of reinforcement 11.It is not this situation that use is used to be positioned at the following one type of prior art syringe that snaps in tooth or striped of this convex shoulder.

Used in this embodiment form on the inwall of shirt rim vertically or vertical ribs, these fins can be plastic deformation on the outer wall of cylindricality neck basic, for example by pushing, neck is provided with the suspension profile.Neck not necessarily will be provided with a lip limit.The distortion of fin can be radially or tangential direction.
