Description

Device for closing containers, and container

The present invention relates to the device of so-called " children can't open " the type can first category vessel of sealing.The invention still further relates to the container that has closing appliance at discharge side.

Children can't be adopted by a series of containers in the open type capping.With the common home-use liquid or solid product that fills, as the capping of the Plastic Drum of purging medium.These cappings need be opened easy, but require and be difficult to based on higher machinery to open for children.An example that addresses this problem is that capping is made and can only be disconnected at some predetermined point.This being sealed on after opening for the first time can only no longer be that children can't open type with common mode closed container.

Liquid is that a rigidity plastics lid is placed on the screw thread for the treatment of closed container with the method for designing that children can't open capping.For example, lid can have two interlocking members, and inner component has sealing thread and can be connected with exterior part by groove.Exterior part is only when being pressed into inner component and groove engagement.Only capping can be opened with the method for rotation in this case.

In addition, known use capping osed top container has screw thread at its opening part.Below screw thread, be shaped on two grooves.The lid made from soft flexible material is screwed in this screw thread.Lid has two projections down, can engaging-in groove in.This capping only can be opened under following situation, when making it become ellipse if its some part is subjected to lateral pressure.So, shift out the rotatable unlatching of lid in the groove of projection down by screw thread of lid.

For the capping of environmental pollution liquid container, also require it can be emptied completely transfer cask.Seal the mode that is fixed on the container and must make the area that does not allow liquid to discharge on the container.And, also must be easy to emit liquid by container.

Airtight and the no leak of the material that capping is contained in must shielding castle.In general, they only must bear usually in family or transportation the stress that container and capping are produced.Yet they also must provide durable and sealing leakproof at capping and can point of transition.

Above-mentioned all children can't the open type capping all have shortcoming, promptly can't satisfy the requirement of transporting packing safely.Can not guarantee the failure-free sealing, particularly because need select to material, for example, hard fragility lid stock, perhaps soft especially capping.And various capping ingear methods are easy to damage or are too complicated.

German utility model application G9206318.7 discloses a kind of device of closed container, and it has the threaded sleeve shaped neck of tightening lid, is shaped on tooth bar on neck and lid, can carry out the detachable interlocking.In order to discharge tooth bar, the sleeve shaped neck must have flexible region.

The device that the purpose of this invention is to provide a kind of closed container, the device of sealing liquid container particularly, it can prevent to cause that in transit the leakproof seal of container loses unexpectedly when mishandling, assurance is easy to and is emptied completely container, and be designed to children simultaneously can't the open type capping, promptly be used in many occasions and still can satisfy these requirements, and allow not rely on to a great extent the material of whole device and simplified design.

Purpose of the present invention realizes with following measure, promptly according to the present invention, provide a kind of and maybe can be fixed on the device that seals closed container on the container with the sleeve shaped cervical fixation, the top of neck is shaped on outside thread, and having the stubborn lid thereon of available screw thread, neck and lid have one or more latching devices radially can carry out the detachable interlocking.The apparatus features of this closed container is that the latching device on neck and the lid all is located at below the screw thread along the direction towards container, designed latching device is a rigidity on lid, and at the neck latching device for can reply the flexible deformation's, and the latching device on the neck is along having the longitudinal extension bar towards the container direction, when lid is in place, these extend the top that bar can pass lid, produce the spot pressure that allows the latching device release.

The sleeve shaped neck has one or more locking elements below screw thread on the direction of container.Locking element can be from making deformable tooth or the deformable lip of arranging at an angle, and for example, it can be the tooth bar that has at least one tooth, preferably has the tooth bar of at least one tooth two relative edges of neck.If desired, can show off under every kind of situation has two or more teeth, but also must make these teeth might leave its position with hour offset.Tooth or lip have the bevelled side on one side, and the arrangement of side makes when lid is tightened in place closing, and the latching device of lid (for example tooth bar) can slip over this dip plane.The another side of tooth or lip can be made into vertical, perhaps has heavy gradient with neck, perhaps has otch, for example, has cavity between sleeve wall and tooth or lip.According to latching device of the present invention is flexible, so it can stress deformation, for example, is pressed into more flat shape.Slid off the latching device of lid like this with regard to the latching device that makes neck.For instance, cause that so also the distance of tooth or lip outside face is dwindled on the neck direction, thus the tooth bar that makes lid locking no longer when opening (unscrewing).

According to most preferred embodiment of the present invention, the neck portion design of apparatus of the present invention is a stabilization, and this mode can prevent the neck pressurized and make the latching device release.For example can one or more central rib particularly be set between relative pressure point realize this stabilization by at spot pressure.Making the further possibility of neck stabilizingization is to center on the neck inwall rib is set, and it can resist undesirable to neck pressurization and realization stabilization.Latching device is opened.Have only the pressure of working as to be applied directly on the spot pressure, when for example being applied on the latching device that can reply the flexible deformation, latching device could release.Central rib is preferably disposed on the inferior segment of the replied flexible deformation's who makes on the neck latching device.Preferably its starting point and terminal point all directly are on the spot pressure in neck.

Lid (and/or packaged unit) has negative thread, and its lower edge is shaped on ring gear as latching device, when lid is tightened the tooth of ring gear can the tooth of engaging-in neck in.If desired, ring gear also can be discontinuous, and is for example, interrupted and have one or more teeth.

Closing appliance seals by mutual the transferring of screw thread, and the latching device of lid (for example tooth or lip) is easy to slip over the inclined side of the flexible latching device (for example tooth or lip) of sleeve shaped neck, and no longer hinders closed process.Tooth on the sleeve shaped neck or lip are arranged to make its length so downwards to extend, promptly after lid placed in position and the sealing, they far protrude from cover part below, thereby can exert pressure to them.For purpose of opening, the bottom of the locking element of sleeve shaped neck can press to together.So, inwardly break away from around property latching device pressurized at the top bullet that is overlapped by lid with the ring gear of lid.

Screw thread can be turned on.After stopping pressurization, pliable teeth is outwards aimed at again and is resiled.So just might open and seal, and not damage closing appliance in many occasions.

The neck of closing appliance and the bottom of neck can be by any material manufacture.It can be rigidity or flexible, because it is to the sealing of closing appliance with open and no longer exert an influence.According to most preferred embodiment, it can be designed as the folding type, can extend as bellows again.If be designed to be similar to bellows, for example, when transportation, be the folding type, and extensible subsequently for longer.If neck or its underpart are made by flexible material then be better, when applying interrupted mechanical strees, the part distortion can be absorbed.Stabilization according to the neck of most preferred embodiment of the present invention can prevent the undesirable release of latching device.Realize the mode of stabilization, the central rib by the neck horizontal expansion for example be set between spot pressure, perhaps at least the spot pressure level the neck interior setting around rib.Flexible preferably lower towards the upper shed material of neck, it is provided with screw thread.This material only allows slight deformation, thereby makes container guarantee sealing in full time.Even when latching device was under pressure, neck material should only have slight deformation, so that easily lid is screwed into screw thread.Make the neck part that is similar to below the ripple area under control with flexible material, also can make by flexible lower or rigid material, make the lower openings of neck be suitable for engaging with container and or fixing, thereby guaranteed that the container failure-free is supported and sealing.This part of neck preferably also is flexible, do not have damage so that meet with stresses under the situation of falling.

For instance, utilization can reach fixing purpose with the design of vessel port ingear collar-shaped.The mode that most preferred embodiment adopts is to be engaged on (for example, the edge of container is a flange) on the container edge from the top.In this case, the advantage that has with the container edge fixed engagement is can reach solvent hermetically enclosed.If desired, the available set collar of this joint is fixed.The device of making in this way is particularly suitable for emptying receptacles and retain residues therein not.

Latching device, for example tooth bar outwardly preferably is formed on two relative edges of screw thread lower, neck end of device neck.The tooth bar latching device can be made either directly on neck or the stable projection, and these projections have below three, is preferably two or tooth or lip.These teeth or lip are towards the outside.They are made and make a flank is bevelled, and another preferably nicked tooth.The inclined side of tooth is arranged on the direction identical with rotation direction in this case, and the rotation direction direction of closure cap just.

The bottom of neck can be provided with screw thread another disposable capping is installed, and it is preferably arranged in last 1/3rd places of depth of thread.For example, it can make the whole layer that connects together with neck.This one deck edge is thinner, therefore can produce along the route of screw thread and tear.Capping is made be similar to bowl-type.Also can be subsequently add one deck closed film at the upper limb of screw thread.For the ease of removing, the method with advantage is to make this part that replenishes the sealing neck have the handle that is easy to tear.This supplementary device also can be used as inspecting containers and whether is in original closed state.

The lid that can be screwed on apparatus of the present invention jar neck has negative thread.The male thread portion of this screw thread and neck coupling, when tightening when in place, it can provide sealing closely.And the bottom of having covered below screw thread has latching device, for example ring gear.It is inwardly so that mesh with following enclosure portion tooth outwardly.These teeth have steep flank, and preferably than the bevelled flank.If desired, these teeth also can have the form of otch.They are arranged in and seal on the direction of direction of rotation.These teeth can be fixed on the wall in a continuous manner, though preferably make these teeth be in the lower edge of lid, are separated by vertical groove each other.

Make by hard material according to lid of the present invention.They can not begun to rotate required pressure distortion.And they have flexible, so they can not destroyed or produce big distortion by potential interrupted mechanical strees.The most handy a kind of like this material manufacture of the threaded area of neck, i.e. its mechanically deform can not cause screw thread sealing forfeiture leakproof seal.Ripple area under control if desired, then its material should be flexible.This requirement or the material that uses with selection reach, and perhaps influence flexible and hardness with different wall thickness.

When sealing, the neck of closing appliance and the threaded portion of lid are engaged to together.They have formed the sealing of container failure-free.By twisting the action of screw thread, the inclined teeth side of lid and neck slides through mutually, and does not need to apply big power.If the direction of rotating is opposite, then vertical or nicked flank engagement and prevented the unlatching of lid.Therefore can not produce unexpected the unlatching because rotate.If the lower extension branch to tooth is exerted pressure, and these teeth preferably are formed in both sides relative on the closing appliance neck, because the flexible result of material makes the tooth deformable.Be positioned at that herein tooth is pressed towards and break away from the tooth of lid.Capping is opened.Because it is flexible forming the material of tooth, above-mentioned opening program can repeat and not influence the leakproof seal of rigid lid material and seal reliability.

When bellow-shaped is made in the bottom of neck, can provide high flexible.Lid at container stands under the situation of mechanical strees, for example falls or when clashing into, can provide high-caliber damage resistance.Also can satisfy the safety requirements in the transportation by this way.The top of the neck below screw thread preferably is not flexible, has prevented its crooked and jam when in place thereby lid is tightened.

The satisfied emptying of container can guarantee by the optimum design of bellow-shaped neck.If bellows is stretched to the prolongation state, then be easy to regard to the liquid in the emptying receptacles.

Bellows is preferably designed as this form, and promptly when bellows was in contraction state, the lid of tightening was positioned at container lid part rising portion slightly.Can not exert pressure to the bottom of latching device with regard to making like this.Therefore lid can not release and container also can't open.

Device according to closed container of the present invention is particularly suitable for sealing the container that fills appearance liquid.Can guarantee chemical resistance with the method for selecting material.Adopt the device of this closed container can satisfy the current required standard and the requirement of transportation safety and aspect safe in utilization.Here sealing makes the lid can be not crooked in screw thread.
