  • Publication number: 20190248546
    Abstract: The present invention provides a sheet material container (90) being made of a sheet material (20) and including a body portion (12) and a bottom portion (25) that is to be disposed on a placement surface, and the sheet material (20) including a plurality of film layers (20a,20b, and 20c). A body portion sheet (93a) that constitutes the body portion (12) includes a bonding portion (94) where peripheral edge portions of the sheet materials (20) are bonded. In a bottom surface sheet (93b) that constitutes the bottom portion (25), a non-adhesive region (99) is provided in the plurality of film layers (20a, 20b, and 20c). The non-adhesive region (99) forms a bottom filler-filled portion (96b). The bottom filler-filled portion (96b) extends annularly around a non-filled portion (96j), and includes at least three protruding leg portions (96m) that are to be placed on the placement surface so as to allow the container (90) to stand by itself.

  • Publication number: 20180208337
    Abstract: A spout-equipped container (100) that is used to refill a refillable container with a content material includes a refill container spout (1) and a flexible container body portion (2). The container body portion (2) contains the content material. The refill container spout (1) includes a tubular nozzle portion (11) that brings the inside and outside of the container body portion (2) into communication with each other, and a fixing portion (19) that is fixedly attached to the container body portion (2). The nozzle portion (11) includes a throttle projection (14) that protrudes toward a center of the nozzle portion (11) on an inner surface (11c) side in a lower portion (C) that is one of three equal parts obtained by dividing the nozzle portion in a height direction of the nozzle portion. The throttle projection (14) forms, on a leading end side in a protrusion direction of the throttle projection (14), a flow path through which the content material passes.

  • Patent number: 9114903
    Abstract: A squeeze container includes a container body having flexibility, and a press restriction member that is provided inside the container body and that restricts, from inside the container body, deformation of the container body due to pressing of a side surface of the container body from outside thereof. A content liquid of the container is discharged by pressing the side surface of the container body from outside thereof. The squeeze container has, on the side surface of the container body, measurement scale markings arrayed in the vertical direction. The inner diameter of the container body within an arrayed range in which the measurement scale markings are arrayed in the vertical direction is formed to have a smaller diameter than an upper portion and/or a lower portion of the container body. Further, there is a corresponding relationship between a position, in the vertical direction, on the array of the measurement scale markings and a discharge amount when that position is pressed.

  • Patent number: 8833612
    Abstract: A container body (11) is provided with a squeeze operating portion (13a) between a shoulder portion (15) and a bottom portion (14), the squeeze operating portion including a squeeze face portion (16) opposed to a squeeze direction X, a pair of lateral support wall portions (17) arranged along the squeeze direction X at both side sections of the squeeze face portion (16), and inclined linking face portions (18) arranged as being inclined therebetween. When the squeeze face portion (16) is compressed to the squeeze direction x, the inclined linking face portions (18) expand distance between the pair of lateral support wall portions (17) at both sides as deforming along the squeeze face portion (16) from an inclined state against the squeeze face portion (16). The inclined linking face portions (18) are restricted so as not to be flipped in the squeeze direction (x) side after deformation completes as expansion force vanishes, so that constant quantity of content liquid is discharged.

  • Publication number: 20120234868
    Abstract: In a cap (10) for a squeeze container to discharge content liquid from a top discharge opening (13) with squeeze deformation of a barrel section (12b) of a container body (12) to be used as being attached to a mouth neck section (12a) of the container body (12) made of plastic as being squeeze-deformable, at least a part of a liquid flow path from the mouth neck section (12a) of the container body (12) to the discharge opening (13) is formed as a helical flow path (15). The helical flow path (15) includes a bottom face section (15a) which is formed to have declination toward the barrel section (12b) of the container body (12) in an erected state of the squeeze container (11). The helical flow path (15) is formed by a helical tube (14) which is arranged inside the cap (10) for a squeeze container, for example.

  • Patent number: 7052752
    Abstract: A blow molding multilayered resin container used for holding contents containing an oxidation dye which comprises a moisture barrier layer having a water vapor transmission rate of 0.4 g·mm/(m2·d) or lower and an oxygen barrier layer having an oxygen transmission rate of 10 cm3·mm/(m2·d·MPa) or lower, the oxygen barrier layer being closer to the outside of the container than the moisture barrier layer.

  • Patent number: 7044334
    Abstract: A double container including an outer container having flexibility and communicating with the outside air, and an inner bag holding contents, with a space defined between the outer container and inner bag. The contents include a component which generates gas by decomposition and a volatile component and the inner bag has permeability to decomposition gases evolved by the decomposing component of the contents. The decomposition gases evolved permeate through the inner bag without difficulty for easy discharge into the outside while the volatile gases evolved from the volatile components are allowed to stay in the space on the outer side of the inner bag, making it difficult for the newly evolved volatile gases to permeate through the inner bag, thereby limiting dispersion of the volatile gases and effectively suppressing deterioration of hairdye.

  • Patent number: 6959840
    Abstract: A cap to be fitted on a double container including a flexible outer container and an inner bag, being composed of a main cap which has a flow opening for discharging the contents and is fixedly fitted on the neck of the double container and a nozzle cap which has an outlet for discharging the contents and is slidably fitted on the main cap. The cap makes a switch between a state with a flow passage shut and a ventilation passage open and a state with the flow passage open and the ventilation passage shut by vertical sliding movement of the nozzle cap on the main cap.
