Abstract

The utility model discloses an automatic seal delivery port structure, the outlet pipe that includes the platykurtic made by flexible material, be provided with straight line shape and/or curved portion of bending at least together on the outlet pipe, during free state, the inner wall of opposite side is hugged closely to one side inner wall of outlet pipe, the straw is crooked naturally along the portion of bending, even hold between the fingers the container hard, liquid in the container can not flow yet, can be with the wall thickness greatly reduced of container, can reduce the use of plastic raw materials in a large number, the cost of products is saved, when liquid is not adorned to the container, can be with container fold and pack, convenient transportation, keep, it uses and carries also to be convenient for the consumer.

Description

A kind of self-closed outlet structure

Technical field

The utility model relates to a kind of packing container, particularly a kind of water flowing out structure of packing container.

Background technology

In the prior art, be contained in the bottle cap on bottleneck, only have the single function opened and cover, such as, the lid on beverage bottle, adopts the mode screwed to be screwed on bottleneck, after opening, if the beverage in bottle does not finish off, need the beverage in bottle to take away, then newly screw on lid with heavy-handed, if do not covered, beverage in beverage bottle is easily contaminated, and when container is overturned, the liquid in bottle can spill.

In addition, for preventing container when pressurized, liquid in bottle can flow out automatically from bottleneck, will increase the thickness of container under normal circumstances, make container have certain intensity, do like this, the raw-material consumption of plastic cement can be increased, add cost of product, and, there is certain thickness product can not fold or compress, a large amount of spaces be taken.

Utility model content

In order to overcome the deficiencies in the prior art, the utility model provides a kind of structure simple, the self-closed outlet structure that sealing effectiveness is desirable.

The utility model solves the technical scheme that its technical matters adopts:

A kind of self-closed outlet structure, comprise the coolant outlet pipe of the flats be made up of flexible material, described coolant outlet pipe is provided with the bending part of at least one linear and/or arc, during free state, the side inwall of described coolant outlet pipe is close to the inwall of opposite side, and described suction pipe is along described bending part natural torsion.

Described coolant outlet pipe is connected to form by the both sides of the edge of two panels film.

The beneficial effects of the utility model are: coolant outlet pipe of the present utility model is the flats be made up of flexible material, coolant outlet pipe is provided with the bending part of linear and/or arc, during free state, the side inwall of coolant outlet pipe is close to the inwall formation sealing of opposite side, suction pipe is along bending part natural torsion, even if firmly pinch container, liquid in container also can not flow out, greatly can reduce thick for wall of a container, the use of plastic material can be reduced in a large number, save cost of product, when container does not fill liquid, can by container FOLD AND PACK, be convenient to transport, keeping, also be convenient to customer use and carry.

Detailed description of the invention

Referring to figs. 1 through Figure 12, a kind of self-closed outlet structure, comprise the coolant outlet pipe 1 of the flats be made up as flexible plastic etc. of flexible material, coolant outlet pipe 1 can be formed by thermal compression welding by the both sides of the edge of two panels soft plastic film, described coolant outlet pipe 1 is provided with at least one along the linear of its Width and/or the bending part 2 of arc, bending part 2 can by hot pressing, the mode such as cold-extruded or bonding is formed, when free state and coolant outlet pipe be not by external force, the side inwall of described coolant outlet pipe 1 is close to the inwall of opposite side, described suction pipe 1 is along described bending part 2 natural torsion, the outside of bending part is stretched, inner side is compressed, make to fit tightly between the inwall in outside in bending part, the inner passage of coolant outlet pipe 1 is closed, even if firmly pinch container, liquid in container also can not flow out.

During use, as long as the kink of coolant outlet pipe 1 is pulled open, it is made to be tending towards straight, because both sides deformation extent inside and outside bending part is different, the inner passage of coolant outlet pipe 1 will be opened naturally, and the liquid in container just can flow out, after discharging water pipe, the elastic reaction of coolant outlet pipe restores naturally, again forms sealing, can prevent the liquid in container from flowing out.

In the present embodiment, more satisfactory bending part has four kinds of structures, and the first structure is see Fig. 1, and bending part is one straight line, the second structure is see Fig. 2, bending part is three road straight lines, is similar to leg-of-mutton structure, and the third structure is see Fig. 3, bending part is the arc of snail web-like, 4th kind of structure is see Fig. 4, and bending part is the S shape be made up of two sections of circular arcs, and bending part also can adopt the combination of straight line and arc.

Self-closed outlet structure of the present utility model can be one-body molded with container, as for soft packaging bag as shown in Figure 9, when initial condition, container and coolant outlet pipe are flake as shown in Figure 5, also the positions such as vessel port are arranged on after can making separately, as shown in Figure 6, be arranged on the bottleneck of plastic bottle, as shown in Figure 7, be arranged on the bottleneck of glass bottle, as shown in Figure 8, be arranged on the water outlet of paper package box, as shown in Figure 10, be arranged on the bottleneck of Soft Roll bottling, as shown in figure 11, be arranged on the water outlet of metal can, as shown in figure 12, be arranged on the water outlet etc. of plastic kettle, because coolant outlet pipe has automatic sealing function, for plastics etc., there is certain flexibility and elastomeric packing container, greatly can reduce thick for wall of a container, the use of plastic material can be reduced in a large number, save cost of product, when container does not fill liquid, can by container FOLD AND PACK, be convenient to transport, keeping, also be convenient to customer use and carry.
