Description

  The present invention relates to a tube container squeezing device, and more specifically, a tube that can quickly and smoothly pour out a substantially constant amount of content from at least one tube container and has a small amount of content in the tube container. The present invention relates to a container squeezing device.

When the contents are poured out from the tube container, the body part of the tube container is generally pressed and squeezed out with a finger. On the other hand, there are also known devices that use a tool to squeeze out the contents of a tube container (for example, Patent Document 1). By attaching a flat press plate to the body of the tube container, the tube is pressed with a finger through the press plate. Some press the container.
Moreover, there exists a set container which pours each content from two tube containers like a hair dye etc., and mixes and uses these contents at the time of use. Such products are also generally used by pressing each tube container with a finger one by one, and squeezing out one component and two components of the hair dye into the tray and mixing them in the tray And use it. Moreover, since there is an inconvenience that the contents must be squeezed out one by one, an instrument (for example, Patent Document 2) that squeezes the contents simultaneously from two tube containers has been devised. This is to squeeze out the same amount of the 1 agent component and 2 agent components of the hair dye simultaneously while winding two tube containers fixed in parallel to the appliance with a hoist.

Japanese Utility Model Publication No. 47-37340 Japanese Utility Model Publication No. 63-26547

However, the conventional methods of use and conventional appliances have the following drawbacks (1) to (4).
(1) If the body part of the tube container is pressed with a finger directly or through a flat plate-like pressing plate as in Patent Document 1, it is difficult to adjust the pressure, and it is difficult to always squeeze out a certain amount of contents. For example, a careful user tries to push out the contents cleanly toward the mouth side by pressing with a finger from the vicinity of the bottom of the tube container flattened by folding or heat sealing. Even if such an operation is performed, it is difficult to always extract a certain amount of contents.

(2) The restoring force after the body part is crushed with a finger differs depending on the material of the tube container. That is, in the case of a tube container made of metal such as aluminum, it is difficult to restore the portion of the body portion that is crushed with a finger directly or via a flat plate holding plate as in Patent Document 1, but a tube container made of synthetic resin such as polyethylene. In this case, a phenomenon in which the crushed portion swells and the contents flow backward, or an air bag phenomenon in which air is sucked into the container is likely to occur. Therefore, even if the above-mentioned careful user presses the synthetic resin tube container with his / her finger from the vicinity of the hem, it is not always possible to squeeze out a certain amount of contents. In addition, in order to squeeze out all the contents, it is necessary to squeeze the portion of the tube container that has been crushed once again, which takes time and effort. In addition, since air enters the container, there is a problem that the contents are deteriorated, and the contents are squeezed out together with the air, so that the contents are scattered.

(3) In a set product in which multiple types of contents such as hair dyes are contained in multiple tube containers, each content is generally dispensed in multiple portions and is constant each time from each container. It is desired to squeeze out the same amount of contents. However, when the contents are squeezed out directly or by pressing with a finger through a flat plate-like pressing plate as in Patent Document 1, the amount of the contents in each container to be dispensed is different, and a predetermined mixing ratio cannot be obtained. There is a problem or only one content is lost first. In addition, there is a problem that the amount of the content to be dispensed changes every time it is used, and an amount of the content unnecessary for the hair dyeing work is dispensed. In addition, there are set products in which the material of the two tube containers is a set product in which the container for one agent is made of metal such as aluminum and the container for two agents is made of synthetic resin such as polyethylene. The work of squeezing out the contents of is made more difficult.

(4) The instrument shown in Patent Document 2 has a problem that the manufacturing cost is high because the structure is complicated and the number of parts is large. In addition, since the body portion of the tube container has a unique cross-sectional shape that swells from the flat hem side toward the mouth side, even if the amount of rotation of the knob portion is always the same, There is a difference between the amount of extraction squeezed by winding up the vicinity of the skirt and the amount of extraction squeezed by winding up the body away from the skirt. That is, even if the instrument shown in Patent Document 2 is used, it is difficult to always squeeze out a certain amount of contents.

  The present invention has been made paying attention to such a problem, and in a set of two or more tube containers such as one tube container or a hair dye, the backflow of the contents regardless of the material of the container. The purpose is to provide a tube container squeezing device that can squeeze out a constant amount of contents step by step in a stepwise manner while preventing spills and air bags, and can be manufactured quickly and smoothly with few parts. And

  In order to solve this problem, the solution means of the invention described in claim 1 is a method of pressing the contents by pressing from both sides with the tube container filled with the contents and the hem and trunk of the tube container sandwiched between them. And a tube fixing means for fixing the tube container to the press plate. (A) The tube container is at least on the press plate so that its body portion faces the surface of the press plate. (B) The push plate is composed of a plurality of push plate pieces partitioned by a partitioning means so that the push plates can be pushed independently and sequentially. After the contents are squeezed out from the container, there is provided a push plate piece fitting means for fixing the tube container so that it cannot be restored, and (c) the tube fixing means is sandwiched, fitted and engaged by the push plate. Tube container squeezed, characterized by being joined or bonded and fixed It is out of the instrument.

  According to a second aspect of the present invention, there is provided the press plate piece fitting means in which the protrusion is formed at the end of one of the press plate pieces and the protrusion is fitted at the end of the other press plate piece. The tube container squeezing device is characterized in that a fitting hole or a fitting recess is formed.

  According to a third aspect of the present invention, there is provided the pressing plate piece fitting means, wherein the undercut is formed at the end of one of the pressing plate pieces, and the undercut is fitted at the end of the other pressing plate piece. This is a tube container squeezing device.

  According to a fourth aspect of the present invention, there is provided a tube container squeezing device characterized in that the partition means comprises a through hole portion and a reinforcing portion that reinforces the through hole portion.

  According to a fifth aspect of the present invention, there is provided a tube container squeezing device characterized in that the partition means is constituted by a groove portion or a hinge portion.

  According to a sixth aspect of the present invention, there are provided two tube containers on a pressing plate, one hair dye for one metal tube container and two hair dyes for the other synthetic resin tube container. The tube container squeezing device is characterized by squeezing out each of the pressing plate pieces while being sequentially fitted.

  According to the seventh aspect of the present invention, in the squeezing out of the tube container, the pressing plate piece corresponding to the vicinity of the skirt portion of the tube container is set as the initial pressing, and then each of the pressing portions corresponding to the vicinity of the trunk portion and the vicinity of the shoulder portion in turn. A tube container squeezing method characterized in that a substantially constant amount of content is always poured out stepwise by pressing a plate piece.

The tube container squeezing device according to the present invention can swiftly and smoothly divide an almost constant amount of content at all times while preventing backflow and air back of the content even when the tube container is made of synthetic resin. In addition to being able to squeeze out, the effect is that the number of parts can be reduced and the manufacturing can be made inexpensively.
In particular, in the case where one and two hair dyes are accommodated in two tube containers, the one-agent container is an aluminum tube container, and the two-agent container is a synthetic resin tube container In the product, it is possible to squeeze out the same amount of 1 agent and 2 agents at the same time, and always squeeze out almost constant amount of hair dye as much as necessary, which makes the hair dyeing work convenient. There is an effect to improve.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

  1-5 is Example 1 which concerns on this invention, pinches | interposes two tube containers 5 between the pressing plates 1, and presses each pressing plate piece 2a, 2b, 2c, 2d sequentially, It is drawing which shows the state which is pushing out the contents of the tube container. The pressing plate 1 is made of a synthetic resin thin plate such as polypropylene. However, the pressing plate 1 can be made of a material such as a paperboard or a metal thin plate, or these materials can be combined. The thickness of the pressing plate 1 is suitably 0.5 to 5 mm, preferably 1 to 1.5 mm. Such a pressing plate 1 may be bent mutually at an approximately middle position in the longitudinal direction of the pressing plate, but the two pressing plates 1 may be used to connect or bond each pressing plate with a thin plate such as a hinge. (Not shown). The tube container 5 is fixed to the pressing plate 1 by fixing means so that the skirt portion and the trunk portion thereof are in contact with the surface of the pressing plate 1. The fixing means may be a method in which the tube container 5 is simply sandwiched between the push plate 1, a method in which the push plate 1 and the tube container 5 are fitted or engaged, or the push plate 1 and the tube container 5. The tube container 5 can be fixed to the pressing plate 1 by fixing means such as a method of adhering. The length of the pressing plate 1 can be arbitrarily determined according to the length of the tube container 5. Further, the pressing plate 1 is divided into a plurality of pieces, each of which is composed of pressing plate pieces 2a, 2b, 2c, and 2d. A partition means, for example, a through-hole portion 3a is provided at the boundary between the pressing plate pieces 2a, 2b, 2c, and 2d. Is formed. The feature of the present invention is that, since the push plate 1 is divided into a plurality of push plate pieces, the push plate pieces 2a, 2b, 2c, and 2d can be sequentially and independently pushed against each part of the tube container 5. In the point.

  Specifically, from two tube containers 5, one agent of hair dye (for example, containing a basic oxidation dye or ammonia) and two agents (for example, containing an oxidizing agent composed of hydrogen peroxide as a main component) Will be described. First, as shown in FIG. 1, when the vicinity of the bottom part of the tube container 5 sandwiched between the pressing plates 1 is pressed by the opposing pressing plate piece 2a, the same amount of the first agent and the two agents in the vicinity of the bottom part are poured out. Next, as shown in FIG. 2, when the vicinity of the lower part of the body part is pressed by the opposing pressing plate piece 2b, the same amount of the hair dye 1 and the hair dye 2 near the lower part of the body part are poured out. In addition, as shown in FIG. 7, after the hair dye poured out from the tube container 5 is mixed in the tray 9, it is apply | coated to hair. In this way, as shown in FIG. 3 and FIG. 4, the vicinity of the central portion of the trunk is pressed by the opposing pressing plate piece 2c, and the vicinity of the upper portion of the trunk (near the shoulder) is stepped by the pressing plate piece 2d. By pressing the tube, it is possible to always pour out a substantially constant amount of the hair dye from the tube container 5 and to pour out almost all of the hair dye.

  Each of these pressing plate pieces 2a, 2b, 2c, and 2d is configured by being partitioned by a partitioning means including a through-hole portion 3a. The dimension of the through-hole portion 3a in the longitudinal direction of the pressing plate (the height direction of the tube container) is suitably 0.5 to 3 mm, preferably 1 mm. Moreover, although the pressing plate 1 of Example 1 is divided | segmented by the four pressing plate pieces 2a, 2b, 2c, 2d, according to the length of the tube container 5, the division | segmentation number can be set arbitrarily. In addition, the length dimension of each pressing plate piece in the longitudinal direction of the pressing plate can be arbitrarily set according to the height dimension of the tube container 5. The length of the plate should be changed. For example, the length of the pressing plate piece 2a located in the vicinity of the flat hem is formed to be the longest, and the lengths of the other pressing plate pieces 2b, 2c, 2d are determined according to the volume of each part before being crushed. be able to. Moreover, since the trunk | drum of the tube container 5 has the unique cross-sectional shape which swells toward the opening | mouth part 6 side from a flat skirt part side, as shown in FIGS. The internal angles α, β, and γ [°] formed by the pressing pieces 2b, 2c, and 2d to be pressed next after pressing the pieces 2a, 2b, and 2c are generally steps such that α <β <γ. Will grow bigger.

  In FIG. 5, two through-hole portions 3 a are formed via the reinforcing portion 4 in the pressing plate width direction (the tube container width direction), but even if three or more through-hole portions 3 a are formed. Good. The reinforcing portion 4 strengthens the connection state between the respective pressing plate pieces 2a, 2b, 2c, and 2d, and can prevent the width of the through-hole portion 3a from expanding. In the drawing, the reinforcing portion 4 has the same thickness as the thickness of the pressing plate 1 and the surface thereof is formed smoothly. However, the thickness may be partially different, and there is an uneven portion. It may be. The length dimension of the reinforcing portion 4 in the width direction of the pressing plate (the width direction of the tube container) is preferably 0.5 to 3 mm, preferably 1 mm so that the width of the through-hole portion 3a is not increased.

  Further, the present invention is characterized in that projections 7 are formed as respective pressing plate piece fitting means in the vicinity of the end portions of the through hole portions 3a of the pressing plate pieces 2a, 2b, 2c, 2d of one pressing plate 1. In addition, a fitting hole 8 for fitting with the projection 7 is formed at the end of the other opposing pressing plate pieces 2a, 2b, 2c, and 2d. As shown in FIGS. 1 to 4, the fitting hole 8 to be fitted with the protrusion 7 corresponds to the portion of each pressing plate piece 2 a, 2 b, 2 c, 2 d after the contents are squeezed out from the tube container 5. And in order to maintain each part of the tube container 5 in the state which pressed so that it cannot restore | restore, it is provided as a means to fit the pressing plate piece of both sides.

  That is, as shown in FIGS. 5A, 5 </ b> B, 5 </ b> C, and 5 </ b> D, the inventor tilts one pressing plate 1 toward the other pressing plate 1 with the tube container 5 interposed therebetween. After the tube container 5 is squeezed and the contents are squeezed out, in order to maintain the squeezed state of the tube container, the protrusions 7 of the pressing pieces 2a, 2b, 2c and 2d at the part where the squeezing is completed are formed in the fitting holes 8. By inserting and fitting, the tube container 5 can be maintained in a state of being pressed by each pressing plate piece.

  In particular, when the tube container 5 sandwiched between the push plates 1 includes a synthetic resin tube container, for example, the two tube containers 5 are metal for hair dye 1 agent containing a basic oxidation dye, ammonia or the like. In the case of a tube container and a synthetic resin tube for two hair dyes containing hydrogen peroxide etc., the following problems due to the restoring force of the tube container can be effectively prevented. The components of the first agent and the second agent can be squeezed out simultaneously and smoothly, and an almost constant amount of the hair dye can always be squeezed out in small portions.

That is, when there is no means for maintaining the fitting state of the pressing plate piece by the projection 7 and the fitting hole 8, the content can be squeezed out by the same amount by the pressing plate piece 2a at the first squeezing. At the stage of pressing the pressing plate piece 2b, the synthetic resin tube container has already swelled by pushing up the pressing plate piece 2a that was initially pressed by the restoring force, and the contents are on the hem side of the tube container ( A phenomenon of backflowing toward the pressing plate piece 2a side or an air bag phenomenon of sucking air into the container occurs. Then, in the second and subsequent pressing operations of the pressing plate pieces 2b, 2c, and 2d, the contents cannot be squeezed out by the same amount at the same time.

  FIG. 6 is a drawing showing Example 2 of the present invention. In Example 2, undercuts 17 having an L-shaped cross-section are formed on both ends of the pressing plate pieces 12a, 12b, 12c, 12d of one pressing plate 11 as pressing plate piece fitting means, respectively, In this embodiment, the undercut 17 is fitted to both ends of the end 18 of the other opposing pressing plate pieces 12a, 12b, 12c, and 12d. As shown in FIGS. 6A and 6B, the tube container 15 is sandwiched between the pressing plates 11, and one pressing plate 11 is pushed down against the other opposing pressing plate 11, and the contents are removed from the tube container 15. After the object is squeezed out, as shown in FIG. 6B, the undercuts 17 formed at both ends of one of the pressing plate pieces 12a, 12b, 12c, 12d corresponding to the squeezed tube container 15 are opposed to the other. The pressing plate pieces 12a, 12b, 12c, and 12d to be fitted are fitted to both ends of the end portion 18. As a result, when the tube container 15 is a synthetic resin tube container, the crushed state after the contents are squeezed out is maintained and the contents flow backward or the air is sucked into the container by the air bag. It can be prevented from occurring. Therefore, it is possible to smoothly squeeze out the components of the first and second hair dyes by the same amount at the same time, and always squeeze out a substantially constant amount of the hair dye.

As described above, the features of the present invention have been described using the first embodiment and the second embodiment as examples. However, the present invention is not limited to the above-described embodiments, and the following embodiments (not shown) are also included in the present invention. Is included.
First, the tube container squeezing device according to the present invention is used for two tube containers composed of a metal tube container containing one hair dye and a synthetic resin tube containing two hair dyes. However, the contents may be mixed and used other than the hair dye, or may be used by mixing three or more kinds of contents from three or more tube containers. Can be applied. Moreover, it can be used also for one tube container which accommodated one kind of contents.

When two or more tube containers are attached to the squeezing device, the material of each tube container may be composed of all synthetic resin tube containers or all metal tube containers. Specific materials for the tube container include the following. As the metal tube container, there is a tube container made of tin or the like in addition to aluminum, but an aluminum tube container is generally used. The synthetic resin tube container includes a tube container having a single layer structure or a multilayer structure such as a polyethylene resin, or a multilayer structure including a polyethylene resin layer and a gas barrier layer such as an ethylene vinyl alcohol copolymer resin or a polyamide resin. A tube container including a tube container, a synthetic resin layer such as a polyethylene-based resin layer, and an aluminum foil layer can be used.
In addition, the tube container may have not only a circular shape but also a polygonal shape such as an oval shape or a quadrangular shape as a cross-sectional shape of the trunk portion.

  Next, in the first and second embodiments, the partition means is formed with two through-hole portions 3a and 13a in the pressing plate width direction (the width direction of the tube container), but only one tube container is the pressing plate 1. Since the through-hole part 3a has a short length in the pressing plate width direction, the reinforcing parts 4 and 14 can be omitted and only one through-hole part 3a and 13a can be formed. In this case, each pressing plate piece is connected to each other only at both ends of the pressing plate.To strengthen the connection state of each pressing plate piece, the length of this connecting portion in the pressing plate width direction is set. It is preferable to form it sufficiently long. Moreover, a partition means is not limited to the through-hole parts 3a and 13a, As another partition means replaced with a through-hole part, you may comprise by the groove part or hinge part which can be bent easily. In this case, the reinforcing parts 4 and 14 may be omitted.

Subsequently, the pressing plate piece fitting means is constituted by the protrusion 7 and the fitting hole 8 in the first embodiment, and the fitting hole 8 is arranged in the vicinity of the through hole portion 3a. The hole 8 may be formed continuously with the through hole portion 3a. Moreover, you may form the protrusion 7 and the fitting hole 8 in the intermediate | middle area | region of each press plate piece in the position away from the through-hole part 3a, for example, a press plate longitudinal direction. Furthermore, the protrusion 7 can be fitted to the end of the through hole 3a, and in this case, it is not necessary to form the fitting hole 8.
In the first embodiment, the fitting hole 8 is formed as a penetrating hole, but it can be replaced with a fitting recess. On the other hand, the tip shape of the protrusion 7 can be a shape that can be fitted to the fitting hole 8 or the fitting recess, such as a cylindrical shape in addition to the spherical shape as shown in FIGS.
Furthermore, a structure in which the fitting state of the pressing plate piece fitting means can be easily released so that the used tube container can be separated from the pressing plate and discarded. In that case, it is preferable that the tube fixing means has a structure that allows the tube container to be easily detached from the pressing plate.

  Further, the squeezing device of the present invention always dispenses a substantially constant amount of content unless the pressing plate pieces 2a (12a), 2b (12b), 2c (12c), and 2d (12d) are pressed in the correct order. Can not do it. Then, you may attach | subject the display (not shown) which shows a pressing order to the outer surface of each pressing plate piece or the tube container 5. FIG. This display can be expressed by any of characters such as numbers and arrows, symbols, figures, colors, or a combination thereof. In order to attach such a display, for example, a known method such as a method of printing, sticking a film or label, engraving, engraving, or a method of forming each pressing plate piece with a material composed of a plurality of colors may be used. it can.

  The press plates 1 and 11 as described above are inexpensive because they are formed by a thermoforming method such as vacuum forming, pressure forming, plug assist pressure forming, etc., in addition to the injection molding method and the compression forming method. . Also, a sheet to be a substrate is prepared, and each pressing plate piece is bonded onto the sheet by a method such as adhesion or injection molding, and each pressing plate piece is arranged so that a gap is formed between the pressing plate pieces. By doing so, a groove part or a hinge part may be formed between the respective pressing plate pieces.

  The tube container squeezing device according to the present invention is particularly convenient for dispensing a hair dye because a constant amount of content can always be subdivided stepwise from the tube container and quickly and smoothly poured out. Since the remaining amount of the contents in the tube container can be reduced as much as possible and can be manufactured at a low cost with a simple structure, it can be widely used as a squeezing device for tube containers such as drugs and foods.
