Description

Zero-contact primary-secondary suction pipe

Technical Field

The utility model belongs to the technical field of the straw, concretely relates to primary and secondary straw of zero contact.

Background

The suction pipe on the market is packaged in a plastic package with multiple single layers, so that the suction pipe is easy to damage in the transportation process, falls out and the like, and pollutes the suction pipe; the single-layer plastic package is easy to touch the straw body when a user takes out the straw, and the straw is in contact with liquid in the cup when the user inserts the straw into the cup, so that pollution is caused, and potential food safety hazards are brought; the suction pipe is easy to fall into the container due to the fact that the size of the suction pipe is not matched when the cup is used, great inconvenience is caused when the cup is used, and liquid is easily drawn by the suction pipe and splashed out of the cup.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model aims to provide a mother-son straw without contact, which has the characteristics of simple structure and convenient use.

In order to realize the purpose, the utility model discloses a technical scheme is: a zero-contact primary-secondary suction pipe comprises a primary suction pipe; a sub-straw is arranged in the mother straw; the outer wall of the mother straw is provided with a push-out groove; the outer wall of the sub-suction pipe is provided with a sub-suction pipe force application push-out end which slides downwards along the push-out groove to control the sub-suction pipe to extend out of the mother suction pipe.

The mother straw is a straw protective sleeve shell

The force applying push-out end of the sub-suction pipe and the sub-suction pipe are of an integral structure, and the sub-suction pipe are sleeved into the main suction pipe together.

The mother straw is made of environment-friendly degradable paper or PE, and the pushing-out end of the sub straw and the sub straw are made of hard plastics.

The opening at the bottom of the push-out groove is positioned at the lower port part of the mother suction pipe, and the upper end of the push-out groove is not provided with an opening.

The push-out groove is provided with a tearing belt.

The utility model has the advantages of it is following:

the utility model has simple structure, totally enclosed package, small occupied volume of package and convenient transportation; in the using process, the user can not touch the sub-suction pipe in the whole process, so that the sanitary and safe effects are realized;

the force application push-out end of the sub-suction pipe can fix the suction pipe besides the function of pushing out the sub-suction pipe, so that the suction pipe is prevented from falling into a cup due to the overlarge size of the cup, namely, the force application end can be clamped on a sealing film or the edge of the cup, and the suction pipe is prevented from falling into the cup; the device has ensured user's food hygiene safety, and the manipulation is simple, realizes with low costs, and the recoverable recycle of protective housing accords with the demand of most audiences to food hygiene, to the demand of green consumption, and market prospect is better.

Detailed Description

The principles of the present invention will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1, a zero-contact mother-son straw comprises a mother straw 1; a sub-straw is arranged in the mother straw; a push-out groove 4 is arranged on the outer wall of the female suction pipe; the outer wall of the sub-straw is provided with a sub-straw force applying push-out end 2, and the sub-straw force applying push-out end 2 slides downwards along the push-out groove 4 to control the sub-straw to extend out of the mother straw.

The mother straw is a straw protective sleeve shell

The force applying push-out end 2 of the sub-straw and the sub-straw 3 are of an integral structure, and the two are sleeved into the mother straw 1 together.

The bottom opening of the push-out groove 4 is positioned at the lower end opening part of the mother suction pipe, and the upper end of the push-out groove 4 is not provided with an opening.

The push-out groove 4 is provided with a tearing belt 5.

The mother straw 1 is made of environment-friendly degradable paper or PE, and the pushing-out end 2 of the sub straw and the sub straw 3 are made of hard plastics.

Be equipped with on female straw 1 and push out groove 4, and be integrative under the prerequisite that does not have external force to tear with the protection cover shell, female straw 1 push out groove 4 tear the structure for reserving, need tear by oneself when using.

Referring to fig. 2, the straw protection casing is a closed integral structure without tearing the push-out slot 4, and only the push-out end 2 of the sub-straw is left outside.

Referring to fig. 3(a) - (c), the process of using the mother-son straw device is zero contact.

The primary and secondary straw device with zero contact is of an integral nested placement structure during the non-use period, and is light in weight and small in size, and is convenient to carry, store and carry.

Referring to fig. 3(a) - (c) the demonstration of the work shows that the working principle of the present invention is:

a user needs to hold the tearing end reserved on the push-out groove 4 in advance to tear off the tearing end; the device is supported on the surface of the plastic package cup (only the upper end of the mother straw 1 is held by hands when the cup without a seal is put in the cup), the thumb is supported on the force applying push-out end 2 of the sub straw to apply force downwards, and the sub straw 3 can enter the cup because the sub straw 3 and the force applying push-out end 2 of the sub straw are integrated; when the pushing-out end 2 of the sub-suction pipe is clamped on the surface of the plastic package cup, the mother suction pipe 1 is upwards drawn away (the sub-suction pipe can be clamped on the cup extension when the sealing is not provided).
