Description

Refill bag plug pipette head

The invention relates to a straw head, in particular to a supplementary bag insertion straw head which can be easily assembled on a supplementary bag body.

In recent years, environmental awareness has risen, so how to make materials reuse has become an important issue. Therefore, whether it is shampoo, shower gel, dishwashing detergent, softener or laundry detergent, in addition to being filled in containers for sale, In addition, there are corresponding supplementary packages introduced to reduce the disposal of waste containers, and the advantages of the supplemental packages are that they are easy to display, replace the packaging of bottles and can be environmentally friendly.

At present, the general supplemental bag is filled with a bag of body contents. When the bag is to be used, the corner of the bag body is cut out by a pair of scissors, and the bag body is suspended above the container to be replenished. The pouring outlet is aligned with the opening of the container, and the filling liquid of the bag body is directly poured into the container for replenishing action. However, the opening of the container has a certain size, and its diameter is not large. When the bag body is suspended and the pouring port is used to pour the replenishing liquid into the opening of the container, the deflection is easily caused to cause the replenishing liquid in the bag to flow to the container opening. In addition, it causes waste of the replenishing liquid and inconvenience in cleaning. In addition, the problem that the replenishing liquid cannot be completely poured out is often caused and needs to be improved.

The inventor has the disadvantages of being easy to flow to the outside and not being able to completely pour out when the supplemental package is supplemented by the conventional inventors, and is based on the idea of creation and creation. After the sample test, and multiple corrections and improvements, the present invention was finally introduced.

The invention provides a supplementary bag insertion pipette head, wherein the insertion pipette head is mounted on the bag body of the supplementary bag, the bag body is filled with a replenishing liquid, and the plug pipette head comprises: a joint, a fixing component and a gasket, wherein the joint has a hollow cylinder having a first end and a second end opposite to each other, the first end is provided with a head, and the end of the head is connected to the hollow cylinder a blocking surface, the head is provided with a through portion at an opposite end of the blocking surface, the head is provided with at least one liquid outlet, and the circumferential surface of the hollow cylinder is provided with at least a second end extending to the stopping portion a groove having a through hole extending from the second end to the head and communicating with the liquid outlet hole, the fixing member is sleeved on the hollow cylinder and rotated in the direction of the head, the gasket The ring is sleeved on the hollow cylinder and sandwiched between the fixing member and the head pressing surface, and the inner edge of the gasket is provided with at least one anti-rotation convex portion for sliding the sleeve in the joint groove. To prevent the gasket from rotating; when in use, the head of the joint is twisted into the bag of the supplemental bag, and the bag body is twisted out of a perforation And the perforated sleeve is placed near the stop surface of the hollow cylinder, and then the rotation of the fixing member is pressed tightly, so that the gasket cooperates with the stop surface of the head to clamp the bag body, thereby ensuring the insertion of the straw head and the supplementary bag body. The solid combination does not leak, so that the replenishing liquid in the replenishing bag is sucked out through the plug pipette head.

The main purpose of the invention is that the plug pipette head can be firmly coupled to the supplementary bag body, and the pipe connection is provided, and the supplementary liquid in the supplement bag is guided to the container by the suction device, and the replenishing action is simple and convenient, and It does not cause waste of replenishing liquid and inconvenience in cleaning.

The second object of the present invention is that the plug pipette head can provide a pipe connection, and the suction liquid can be used to guide the replenishing liquid in the replenishing bag to the container for replenishment, so that the replenishing liquid in the replenishing bag can be completely sucked out to avoid formation. waste.
