Abstract

The present invention relates to a container for dispensing flowable substances, which comprises a pair of rigid walls which are connected through walls in a wind box shape and abdominal walls. The container can be in an open state (the rigid walls are separated) or in a folding state (the rigid wall are parallel and are compressed.), and simultaneously, the rigid walls also provide an effective labeling surface for the container.

Description

Collapsible Container for flowable substances

The present invention relates to a kind of collapsible container of sending flowable mass.

Disclose a kind of collapsible container in 3,506, No. 163 US Patent of Ranh etc., in order to dispensing various materials such as from cosmetics to food, this material can be full-bodied, even liquid or stream material also can be sent.

Disclose a kind of container of variable volume in 3,494, No. 509 US Patent of McGuire, be mainly used in fuel system, this container is made by the dividing plate that the bellows-shaped member connects with two centres, like this, two dividing plates are relatively moved and makes container folding.

A difficult problem that is run in the packing is how to obtain a kind of container that can thoroughly dispense out inner material, simultaneously, can provide actv. labelled surface again.On the packaging Problems of flowable mass, how a kind of container that can carry out carrying and storage effectively is provided also is a difficult point.The container of flexible material normally can not fold, and promptly enables to be folded, and it be returned to the state that needs filling dispensing material, and is also very difficult.Usually, container has the cross-sectional plane of a circle or arc, and when carrying, such container needs sizable space, and just carrying is only economical in short relatively distance.Equally, also existing difficulty aspect the carrying of container and the storage.

According to being sent Substance Properties, it also can be crucial keeping the germ-free condition of quilt dispensing material in the container.In addition, if higher, guarantee that so the material in the entire container can be sent away significant by the cost of dispensing material.

For this reason, it is folding so that carry out the carrying and the storage of less expensive that main purpose of the present invention provides a kind of energy, and can send the container of stream material.And this container can provide the surface of being convenient to put up label.

According to the present invention, container is made up of the wall that is generally rigidity that the folding wall of a pair of usefulness connects.When container was filled by the dispensing material, folding wall was extended configuration; Folding wall is folding state after having been sent by the dispensing material.

In one embodiment, folding wall constitutes the base, and rigid walls stretches upwards from the base, and when transporting container, rigid walls is drawn close each other, and like this, container has constituted the folded formation of an ordinary flat.Container has perforate, make to be charged into container by the dispensing material by perforate, and the hole will be sent away by the dispensing material thus.Rigid walls can be a planar shaped, and perhaps with circular arc, rigid walls provides fabulous surface for labelling.

When container charged into material, its base had reached maximum area, and same, after material was sent, container base area became minimum.After material was sent away in the container, firm rigid walls made the base continue to have sufficient supporting role.

In the carrying process, container collapsible and have minimum volume so as the shipment.This feature has not only guaranteed to transport container economically, and is convenient to storage container before use.

Container can be made into various shapes, so that when container is full of material, these container dresses can not wasted space, any point in fact, and therefore, container all is convenient to effectively adorn when folding or charging into material and is deposited.

Folding or opening under the condition, container should have a fixing size at least, when container opens, according to its shape, then has two fixed measures.

In a preferred container embodiments, under its open configuration, container on its whole height or the cross-sectional plane parallel with its base be leg-of-mutton generally.Folding wall has telescopic bellows-shaped structure between two rigid walls, can make the container that is in folded state have flat base, has formed a long and narrow oblong base.

Be the operational advantages of understanding this container better and having a definite purpose of in use can reaching thereof, can be referring to accompanying drawing and declaratives; In accompanying drawing and declaratives, illustrate and narrated preferred embodiment of the present invention.

In the accompanying drawings:

Fig. 1 is the front elevation of collapsible container embodiment of the present invention;

Fig. 2 is the lateral plan of container among Fig. 1, is shown with the dispensing discharging opening;

Fig. 3 is the view similar to Fig. 2, is the folded state after container shown in the figure is in flattening, and discharging opening is not shown;

Fig. 4 is the transparent view with the roughly the same container in Fig. 2 visual angle;

The transparent view of container when Fig. 5 is opposite with Fig. 2 visual angle.

In the accompanying drawings, label 1 Foldable vessel that refers to.Container has a base 2 in order to support vessels it to be remained on a certain bearing surface.Container is the limit wall 3 that has the planar shaped of being substantially by a pair of, and forms on the base with along the folding wall 4 of limit wall height commissural flange wall.Above-mentioned limit wall 3 links along respective edges and stomach wall 5, sees Fig. 4 and transparent view shown in Figure 5.

Discharging opening 6 as shown in Figure 1, discharging opening 6 in Fig. 2 ' be another plan of establishment is not represented discharging opening among Fig. 3.Figure 2 shows that the open configuration of container, Fig. 3 represents that then container is in collapsed state.Container top has a perforate 7.For the filling stream material is provided with, after being connected, discharging opening just becomes the dispensing outlet of stream material.

For the dispensing material can push rigid side wall 3 relatively, the internal tank material is flowed out by discharging opening 6.Sealing arrangement according to discharging opening can be set by the kind of dispensing material inner material can be flowed out, and in dispensing after hours, air can not enter.

Send sterile substance, can use the valve that July 13, Gerber was proposed in 1987 in 072, No. 534 U.S. Patent application.

The surface of limit wall 3 should be a planar shaped, but also can adopt the wall of roughly smooth cambered surface so that adhesive label.

In general, above-mentioned limit wall is linked by stomach wall 5, like this, the limit wall just can be between open configuration shown in Figure 2 and folding or collapsed state shown in Figure 3 the phase co-conversion, the position of stomach wall is to be selected in along the stomach wall height, still on the top of limit wall, decide according to project organization.

Container can be made with various plastics, as polyethylene etc.

Folding wall 4 has bellows-shaped structure, and limit wall 3 links and can open between limit wall 3.Folding wall 4 should be able to make the total material in the container send away with respect to the position of discharging opening.

As shown in Figure 2, when container was in open configuration, the folding wall of container bottom bellows-shaped made each adjacently situated surfaces of internal tank be the divergence shape.When container was unloaded before and after filler, its rigid walls was from the inside rotation of state shown in Figure 2 and become complete flat state shown in Figure 3, and the bottom of folding wall 4 is folded into flat form among Fig. 3 between rigid walls 3.

When not being with discharging opening, container can adopt the action as the bellows blowing mould, become flat form fully after, be contained in and transport any required part in the box to.When prepare using container, it is full of stream material, and load onto discharging opening 6,6 ', can begin operation.Personnel that are familiar with this respect technology are understood that, can change whole structures of container at aspects such as function and aesthetics.

Principle of the present invention has been done detailed narration and illustrated by specific embodiments of the invention, be appreciated that and also can make other embodiment and not break away from these principles the present invention.
