Abstract

ภาชนะของเหลวหนึ่ง ประกอบด้วยตัวภาชนะรูปถุงอ่อน 1 ซึ่งมีส่วนแบนสอง ส่วน 3 (3a , 3b) เป็นผนังหน้าและหลัง และส่วนเสริมแรงสองส่วน 4 (4a , 4b) เป็น ผนังข้างซึ่งพับเข้าใน และหน่วยส่งรูปท่อ 2 ซึ่งมีส่วนปาก 11 ที่ปลายบนของตรงนั้น ที่ จะยื่นออกจากส่วนปลายด้านบนของตัวภาชนะ และ ส่วนขอบเสริมแรง 12 ใต้ส่วนปาก ที่จะนำมายึดที่ส่วนเชื่อมต่อ 5 ของส่วนปลายบนของตัวภาชนะ ซึ่งแต่ละส่วนเสริมแรง 4 มีความกว้างประมาณเท่ากับส่วนแบน 3 ส่วนปลายเข้าใน 15 (15a , 15b) ของส่วน เสริมแรงสองส่วนที่ซ้อนระหว่างส่วนขอบเสริมแรง 12 และส่วนแบน 3 ที่ส่วนเชื่อมต่อ 5 เมื่อผลิตภาชนะของเหลว เป็นการควรที่เชื่อมต่อชั่วคราวฟิล์มสำหรับส่วนเสริมแรง เข้ากับฟิล์มสำหรับส่วนแบนก่อนการวางตำแหน่งของหน่วยส่ง One liquid container It consists of a vial-shaped container 1 with two flat sections 3 (3a, 3b) forming the front and back walls. And the two reinforcement sections 4 (4a, 4b) are side walls which are folded in And the pipe-shaped transmission unit 2, which has a mouth section 11 at the top end of that area that extends from the top end of the container, and the reinforced edge 12 under the mouth section to be fixed at connection 5 of the section. Upper end of the container Where each reinforcement 4 is approximately the same width as the flat 3, the ends in 15 (15a, 15b) of the two reinforcement sections overlaid between the reinforced edge 12 and the flat 3 at the connection 5 when manufacturing the container. liquid It is wise to temporarily connect the film for the reinforcement. To the film for the flat part before the positioning of the sending unit

Claims

1. a container of liquid that contains The bag-shaped container is made of soft film and consists of two-sheet sections that make up the front and back walls. And two reinforcement parts Which is folded in and the side wall of the container and the tubular transport unit with at least one lip located at the top end of there and extending from the upper end of the container and the reinforced edge located under the lip section. say It is fixed at the upper end of the container as a connection between the sending unit and the container, while each reinforcement is approximately equal to each flat width. Inlet end of two reinforcement sections Which extends into the body of the container to be stacked Between the reinforced edge and the flat part at the connection

2. Liquid container according to claim 1, which the said unit. There is also a conveying section underneath the reinforced edge and protruding into the container.

3. Liquid container according to claim 1, in which both ends of the two reinforcement sections are placed on the same side as the edge of the reinforcement.

4. Liquid container according to claim 1, which seals the said container at each of the four corners of The bottom of that. Along each of the four seals Which extends from the flank edge to the bottom edge of there And through the part where the reinforcement folds and the container bottom seal are cut across each other And cut out a trapezoid on the outer part Beyond each sealing barrier And the seal line

5. Liquid container according to claim 1, which seals the said container at the upper end of the thereon, along the upper seal. Which extends from the connection outward and is larger than the width of the connection seal. One edge of each section is connected between the lower corners. Of the connecting part And the bottom edge of the upper seal that extends significantly parallel to the axis of the container.

6. Liquid container according to claim 1, in which the soft film is a composite film composed of polyester film coating. To be the outermost layer One film capable of film protection, one chosen from a group consisting of a polyether film or nylon film and polyethylene film. That will be the innermost in this order

7.Production method for liquid containers with bag container bodies. And a pipe-shaped transmission unit that It consists of the steps of having one (1) pair of [The second prepared] film can bend. To be made into sections The flattening is formed as each of the front and rear walls of the container body (2). The second [two other] pairs of film are bent. [Each one has an approximate width of the film. For the flat sections] to be made for each pair of gusset portions that form a pair of side walls of the container body. And each part is reinforced Such triangle With approximate width equal to each of the flat sections and (3) conduit-shaped transmission units. With at least part of the mouth Built on the upper end and the fins built under the mouth; One pair of [two] overlays of the film can be bent [for] to create a flat section. Onto each other The second double fold of the film is bendable. To be each pair of triangle reinforcement With the end into the assembly Filed into the container body And positioning [two films for] each pair of reinforcement sections. Between two overlapping films [for] that will form a flat portion [in the state] at the ends of both ends.
