Abstract

PROBLEM TO BE SOLVED: To rationally and economically pour paste for screen printing. SOLUTION: In the paste container wherein the periphery of a housing bag 1 having proper hardness and flexibility is set to a closed state, a slit line 9 is provided at a part leaving a slight interval from sealed parts 2 and 2' provided to one side part in the longitudinal direction of the housing bag 1 so as to provide an interval across both left and right side edge parts of the housing bag 1. A free piece 10 is molded in a raised state at the interval part with the sealed parts facing to the slit line and a pressure-sensitive adhesive tape is bonded to the upper surfaces of the slit line and the free piece to hermetically seal the housing bag 1 to house printing paste (a).

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paste container for screen printing. 2. Description of the Prior Art Conventionally, pastes used in screen printing machines are extremely expensive, but pastes applied in large quantities in a lump on a screen plate are flattened with a spatula. In this method, a large amount of paste that costs tens of thousands of yen or more remains on the screen plate and is discarded, resulting in a large economic loss. Since the change is apt to occur, there is a disadvantage that the printing characteristics are significantly deteriorated. [0003] Accordingly, an object of the present invention is to eliminate the drawbacks of such means and to provide a receiving container in which an expensive paste can be used reasonably and economically. It is assumed that. SUMMARY OF THE INVENTION The present invention is directed to a paste container in which the periphery of a storage bag having appropriate hardness and flexibility is closed, and one side in the longitudinal direction of the storage bag is provided on both left and right sides. A cut line is provided at a portion slightly spaced from the sealing portion provided at intervals over the edge, and a free piece is formed in a rising shape at a space between the sealing portion facing the cut line, An adhesive tape is adhered and sealed on the upper surface of the cut line and the free piece to accommodate the printing paste. [0005] Now, after the present storage bag is installed at a predetermined position of a screen printing machine for producing a semiconductor substrate, the printing paste a inside the present storage bag is printed on a base b by a printing object c. And the screen plate d, the adhesive tape is first pulled slowly with a knob. Then, the paste inside the storage bag tries to come out from one cut line by peeling off the coated adhesive tape,
At this time, the free piece in the rising state facing the cut line prevents the paste from naturally flowing out. Therefore, the work is performed such that the paste is slowly poured out and supplied by the pressurization by the pressing member from the opening of the cut line portion of the main storage bag installed at a predetermined location of the printing press. Become. DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a storage bag for a printing paste in which the whole is rectangular and the four side edges are closed, and the storage bag is made of LL, nylon and PE. ,
It is transparent and has appropriate hardness and flexibility. Reference numerals 2 and 2 'denote sealing portions provided on one side in the longitudinal direction of the paste accommodating bag 1 so as to extend in parallel to the left and right side edges. Sealing parts 3, 3 'are provided in parallel to the edge. Reference numeral 4 denotes a sealing portion provided on one side in the short direction of the paste storage bag 1 and extending over both upper and lower edges. A stop 5 is provided. Reference numeral 6 designates a mounting hole provided on one side of the paste storage bag 1, through which the storage bag 1 is mounted at an appropriate position above the screen printing machine base. Reference numeral 7 denotes a sealing portion provided obliquely at the upper end on one side in the longitudinal direction of the paste storage bag 1, and an oblique sealing portion 8 is provided on the other side portion of the sealing portion relative to the sealing portion. Reference numeral 9 denotes a cut line provided between the diagonal sealing portions 7 and 8 at a portion slightly spaced from the inner sealing portion 2 '. The sealing portion 2' facing the cut line. Is a free piece 10, which is formed in a slightly upright shape. The opening 1 of the free piece 10 by the cut line 9
From No. 1, paste a comes out. Reference numeral 12 denotes an adhesive tape which is adhered and sealed to the cut line 9 and the upper surface of the free piece 10. One end of the adhesive tape serves as a knob 13. Reference numeral 14 denotes a fixing tape provided at the upper end edge of the paste storage bag 1 in the longitudinal direction. A fixing tape may be provided at the lower end edge of the fixing tape relative to the fixing tape. With this fixing tape, the form of the flexible paste containing bag 1 is firmly held. Since the present invention has the above-described structure, even if the adhesive tape covering and cutting the cut line is peeled off during use, the internal paste is immediately removed. It does not leak out of the score line, but is always blocked and prevented by the free piece that is set up and standing on the score line. Since it is supplied to the screen plate surface, it is possible to perform an extremely suppressed and smooth supply operation. Therefore, the required amount of the expensive paste is always supplied and used, so that a large amount of wasteful use can be prevented and a reasonable operation can be performed.
