Problems solved by technology

However, when the conventional push pump is screwed onto the flexible packaging stand-up pouch welded with a hard circular mouth above, the self-weight of the pump often makes the flexible packaging bag bend, and there is no way to pump the packed liquid by pressing the above-mentioned push pump. out

Embodiment 1

[0029] Such as Figure 1-3 As shown, the stand-up press pump stand-up pouch is composed of a stand-up pouch body 5 made of soft packaging material and a stand-up press pump. The top of the stand-up pouch body 5 is welded and sealed with a round mouth 51 whose outer wall is provided with threads, and the standing press pump can be inserted into the stand-up pouch body 5 from the round mouth 51 . The standable press pump is composed of a pump head 1 and a guide tube communicating with the pump head 1. The pump head 1 is provided with a screw cap 11 that matches the thread of the circular mouth 51 and its outer wall, and the stand-up bag body 5 and The standable press pump is assembled as a whole through the screw connection of the circular mouth 51 and the screw cap 11 .

[0030] The above-mentioned guide tube is formed by connecting a rigid hollow conduit 2 and a standing part 3 connected to the bottom of the rigid hollow conduit 2. The material of the rigid hollow conduit 2 a...

Embodiment 2

[0035] In this embodiment, the stand-up pump stand-up pouch is composed of a stand-up pouch body and a stand-up push pump, and the connection relationship between the two is the same as in Embodiment 1.

[0036] In this embodiment, the rigid hollow conduit of the standing press pump is made of high-density polyethylene (HDPE), and the standing part is made of nylon (PA), which are respectively made by stretching tube method and injection molding process, and are connected through matching Mechanisms (such as plug-in mechanism, screw-connection mechanism, snap-in mechanism) are connected as one. The standing part is an enlarged body with a diameter larger than that of the hard hollow conduit, the bottom surface of which is a downwardly convex arc surface, and the top of the enlarged body is connected with the bottom end of the hard hollow conduit. Other parts are identical with embodiment 1.

Abstract

The invention belongs to the field of packaging and particularly relates to a standable pressing pump bag capable of self-standing. The pressing pump bag comprises a bag body made of soft packaging material. A round mouth with threads on the outer wall is solder sealed at the top of the bag body. A standable pressing pump is inserted into the bag body through the round mouth and comprises a pump head and a guide pipe communicated with the pump head. The pump head is provided with a rotary cover matched with the round mouth and the threads on the outer wall of the round mouth. The bag body and the standable pressing pump are integrated through the round mouth and the rotary cover. The guide pipe is formed by a hard hollow duct and a standing part connected to the bottom of the hard hollow duct. The guide pipe is capable of self-standing and bearing pressing pressure. When the bottom of the hard hollow duct is disconnected with the standing part, a through hole allowing substance outside the guide pipe to be communicated with an inner passage of the hard hollow duct can be formed. By the standable pressing pump applied to the soft self-standing bags, production cost and transport cost of liquid product packages can be lowered effectively.

Description

technical field [0001] The invention belongs to the field of packaging and relates to a stand-up pouch. Background technique [0002] The packaging of liquid products on the market (such as shower gel, dishwashing liquid, etc.) is mostly hard bottle packaging. For the convenience of consumers, hard bottle packaging on the market is often equipped with a push pump, so that consumers can easily pump out the product in the package. The above-mentioned push pumps are usually combined with a screw cap and a hard bottle body. At the same time, the lower end of the pump is a hollow soft conduit, and the conduit can extend to the bottom of the bottle to absorb as much liquid in the package as possible. [0003] At present, the flexible packaging stand-up pouch has become the development trend of replacing the hard bottle packaging in the above-mentioned liquid product packaging field due to its advantages of less material, saving storage and transportation space, and low cost. ...
