Abstract: The present invention provides a gusset bag in which a sufficient area for indication can be retained on flat surfaces, paying attention to the structure of the gusset bag. The gusset bag 1 of the invention comprises flat surfaces 2 and 2 opposed to each other; and side surfaces 3 and 3 capable of being tucked in at creases by connecting the both ends of the flat surfaces 2 and 2; wherein a part of the side surfaces 3 and 3 is made transparent to form windows 9 and 9. Since windows 9 and 9 are provided on the side surfaces 3 and 3, it is possible to retain a sufficient area for indication in the flat surfaces 2 and 2, and observe the contents from outside.

Abstract: A plastic container comprises a main body, a large-diameter member and a small-diameter-formed member. The main body is formed of a plastic laminate film into a tubular shape. The large-diameter-formed member is joined to the outer surface of the end of the main body by an insert-injection process. The small-diameter-formed member is jointed to the inner surface of the other end of the main body by the insert-injection process.

Abstract: A self-standing container comprises a tubular main body and a bottom-forming sheet. The main body has upper and lower end portions, which are opened. The bottom-forming sheet is joined to the periphery of the lower end portion by a fusion-bonding so as to form a self-standing container having a flat bottom. Each of the main body and the bottom-forming sheet comprises a laminate film having at least two layers. Each of the at least two layers has a thickness of from 20 &mgr;m to 120 &mgr;m.

Abstract: A gusseted bag for medicinal or medical purposes comprises a gusseted bag body formed of a plastic film into a hollow shape; and a sealed portion formed at a bottom of the gusseted bag body. The plastic film is a laminate composed of a plurality of layers. The innermost layer of the plurality of layers essentially consists of polyethylene.

Abstract: A liquid container comprises a bag-shaped container body formed of a flexible film and a delivery unit having a mouth portion, a joining portion and a shank portion, the joining portion being secured to an opened end portion of the bag-shaped container body, the mouth portion extending outward of the bag-shaped container body from the joining portion and the shank portion extending inside the bag-shaped container body from the joining portion. The joining portion and the shank portion of the delivery unit are connected to be relatively rotatable with each other by an engaging member such as pin-and-hole connection or other flexible member such as bellows.

Abstract: A bag for an infusion solution has front and back wall portions each formed of a flexible plastic film and provided with a plurality of chambers which are filled with one infusion solution and another infusion solution or medicament, independently. The chambers are sectioned by a boundary portion having at least one weak seal portion which is closed by separably bonding inside surfaces of the plastic films mutually facing at the boundary portion so that the one infusion solution and the another infusion solution or medicament in the respective chambers are mixed together when the weak seal portion is opened. The weak seal portion is formed by applying a separable coating material, which provides a reduced bonding strength in a heat sealing process, on one or both inside surfaces of the plastic films mutually facing at the boundary portion and then effecting heat sealing process to the boundary portion. The separable coating material is applied in a form of a dot-pattern through a printing process.

Abstract: A package material processing machine comprises a feeding device for feeding a package material along a predetermined feed course and a processing roller having an outer circumferential surface opposite to the feed course. The package material is processed by rotating the processing roller with feeding the package material along the feed course.

Abstract: A packaging bag comprises a tubular body obtained by joining opposite ends of a strip film comprising a lamination of oriented and non-oriented films to each other so as to form a longitudinal sealed portion. The tubular body has at opposite sides in its diametrical direction crease portions, respectively, and has at opposite edges in its longitudinal direction lateral sealed portions, respectively. The crease portion has the first tearable zone, which can be torn at longitudinal different positions. The longitudinal sealed portion is located on the back surface side of the bag and has the second tearable zone, which can be torn at longitudinal different positions. The second tearable zone has a length identical with or longer than that of the first tearable zone. The upper edge of the second tearable zone is located in the same level as or above the upper edge of the first tearable zone and the lower edge of the former is located in the same level as or below the lower edge of the latter.

Abstract: A package is composed of an inner box accommodating an inner content and an outer packing member essentially formed of a plastic film layer and adapted to wrap the inner box so as to have end portions to be bonded in a projecting manner through a heat sealing process. A pair of notches are formed to an end edge portion of the bonded end portions of the outer packing member and the packing member is provided with an easily opening portion at a portion near a base portion of one of the projected bonded end portions so as to correspond to the paired notches. In another aspect, a carton package comprises a carton body having an opened end, a pair of lid pieces formed integrally with the carton body and a carton tape applied to mating end edge portions of the lid pieces when closed, the carton tape having a tearing portion, from which the carton tape is easily torn, formed so as to extend in a longitudinal direction of the carton tape at a central portion in a width direction thereof.

Abstract: A container comprising a combination of a flexible inner container and a hard outer housing for holding the inner container therein is disclosed. The flexible inner container comprises a cylindrical mouth for dispensing contents of the container. The cylindrical mouth comprises a passage for pouring the content and engagement grooves provided on both sides of the outer periphery of the mouth with respect to the passage. The hard outer housing comprises four side walls one of which has a large opening, an upper wall having a pair of guide portions sandwiching a guide notch which is opened to the large opening of the outer housing and extends to approximately the center of the outer housing, and a supporting member for supporting the container which projects in the outward direction of the flexible inner container and which is connected to the ends of the guide portions in the side of the large opening.

Abstract: The liquid-pumping container according to this invention comprises: a container consisting of a flexible bag for containing a liquid substance and an outlet block positioned at the top of the bag and provided with an outlet hole for outlet of the liquid substance, a cover block mounting portion, and a box fixing portion; a cover block which is liquid-tightly mounted on the cover block mounting portion of the outlet block; a pump mechanism provided on the cover block for pumping out the liquid substance from the bag; and a box consisting of a pair of box components which are connected to each other through hinge sections for containing the bag by fixing the outlet block on a support block of the box when the box components are closed. The liquid-pumping container has a structure which simplifies the replacement procedure of the bag containing the liquid substance and reduces the cost of manufacturing.

Abstract: A holder for containing an inner flexible container comprising side walls 15, a bottom wall 16 and a top wall 17 is disclosed. The side walls 15 comprises; a first side wall having a handle 18 projecting in an outer direction, a second side wall having an open window 19 provided in a lower position thereof, a third side wall which is opposite to the second side wall and the upper portion of which has an opening 20 opened to the top end thereof. The top wall 17 has a guide notch which is opened in the opening 20 above the third side wall. The flexible inner container is inserted into the holder in an inclined state through the upper opening 20 of the third side and then is stood in an erect posture, interfitting the mouth of the flexible container into the guide notch of the top wall 17. The contents is dispensed through the mouth by using a torque lowering the side wall which is positioned opposite to the ear 18.
