Description

  The present invention includes a shrinkable inner container on the inner side of an outer container, and a comb having an air introduction path for introducing air between the inner container and the outer container on an upper part of a comb cap attached to the mouth tube portion. Concerning double containers.

  The double container with a comb is composed of, for example, a delami bottle and a cap with a comb that is assembled to the mouth part of the delami bottle. You can comb the hair with your teeth and attach the drug.

  There are many types of hair dyeing agents in which the main agent is mixed with an auxiliary agent (such as an activator). In such a case, the main agent is stored in advance in a container body such as a delamination bottle. After being injected into the main body and mixed with the main agent, a cap with a comb was assembled to the mouth tube portion and used.

  The delamination bottle is formed so that the inner container can be peeled from the outer container, and when the outer container is pressed, the inner container is also pressed and the content liquid is poured out. Air flows in between. And when the outer container is pressed next, the outflow of air from between the outer container and the inner container is stopped by an air valve or the like, and a pressing force is applied to the inner container. However, the contents are always poured into the comb teeth.

  As a method for allowing air to flow in one direction between the outer container and the inner container, for example, an air valve is assembled outside the mouth tube portion of the container body, and when the outer container is pressed, the air valve is closed and the outer container and the inner container are closed. When the outflow from the outside is stopped and the outer container is released from the pressure, air is taken in through the air valve from the opening formed above the comb-attached cap, and the air inlet is formed on the side of the mouth tube portion of the container body. It is known that air is introduced between the outer container and the inner container through the through hole.

In general, a cap with a comb is formed by injection-molding a comb composed of a plurality of comb teeth, a support shaft to which the comb is assembled, and a cap portion to which the support shaft is attached, and fitting them together. Conventionally, a groove is provided in either the support shaft or the cap portion, and when the support shaft is assembled to the cap portion, an air introduction path for introducing air into the comb cap is formed by the groove. Furthermore, when the air introduction path is formed using a groove, the air introduction path is formed in the shape of the groove in the combination portion of the support shaft and the cap portion, so the air introduction path is formed below the comb teeth, The opening was made inconspicuous.
JP 2001-321222 A

  However, when the air introduction path is opened below the comb teeth, the liquid content flowing down from the comb teeth may block the opening. Then, even if the pressure is released and the container body is restored, air does not flow in from the air introduction path, and there is a possibility that it is misunderstood as a container that has a weak restoring force and is difficult to use.

  In addition, the groove for forming the introduction path cannot be formed with protrusions or dents for assembling the support shaft and the cap portion. If a large number of grooves are formed, the force for holding the support shaft may be reduced. Conceivable. Further, when a wide groove is formed in one place, there is a problem that the assembling strength is reduced at that portion, and the force for holding the support shaft becomes uneven in the circumferential direction.

  Furthermore, the opening part of the air introduction path is provided over the assembly line between the support shaft and the mounting part, and furthermore, it opens in the shape of a groove, which is a great limitation on the design of the double container with a comb.

  It is an object of the present invention to provide a double container with a comb in which an air introduction path that is not easily blocked by the content liquid and that is excellent in design is opened on the outer wall of a cap with a comb without increasing the number of manufacturing steps. Objective.

  In the double container with a comb, an air introduction path communicating with the inside of the cap part is formed by penetrating the outer wall of the base part (attachment part) provided on the top wall of the cap part. The cap portion has a cylindrical shape with a top, has an internal thread on the inner surface, and is molded by injection molding from a synthetic resin. The base part may be integrated with the support shaft provided with the comb teeth, or may be a connecting part formed on the top wall of the cap part in order to attach the support shaft to the cap part, separately from the support shaft. . The base part is formed in a substantially truncated cone shape, and when formed as a connecting part, the base part has a hole into which the support shaft is inserted.

  The air introduction path opens in the inclined outer wall of the mounting portion. A plurality of openings are formed evenly in the circumferential direction of the outer wall at a position avoiding a position immediately below the comb teeth along the axial direction of the container. That is, the shape and the arrangement of the openings are uniformly formed so that the air inlet is not opened below the comb teeth. The air introduction path is preferably provided on the outer wall in parallel with the central axis of the cap portion. Then, since the outer wall is formed in the shape of a truncated cone, a vertically long opening having a sharp upper portion is evenly formed in the outer wall.

  Further, a protrusion for forming an air introduction path is provided in a portion where the base part (attachment part) of the injection mold is molded, and the air introduction path is formed by injection molding. In addition, you may form each opening part in a shape and arrangement | positioning different from each other not equal.

  According to the double container with a comb of the present invention, since the air introduction path can be opened in an arbitrary shape, the air introduction path can be provided in a conspicuous portion of the container. Since the air introduction path is not opened below the comb teeth, even if the content liquid flows down from the comb teeth, the opening portion is not closed by the content liquid, thus providing an easy-to-use double container with a comb. it can.

  Since the air introduction path is evenly opened around the side wall of the base part (mounting part), the opening of the air introduction path can be used as a design of a cap with a comb to improve the appearance of the double container with a comb. it can.

  An air inlet can be formed by newly providing a protrusion on a mold for injection-molding the cap portion, and the manufacturing process is not increased, and an inexpensive double container with a comb can be provided.

  FIG. 1 shows a double container with a comb.

  The double container 2 with a comb includes a cap 4 with a comb and a container body 6, and a letter “A” as a product name is printed on the front. The comb-attached cap 4 is screwed to the mouth tube portion 8 (see FIG. 5) of the container main body 6, and a content liquid (not shown) such as a hair dyeing liquid is provided inside the comb-attached double container 2. ) Is stored.

  The comb cap 4 is formed of a comb 10 and a cap portion 12.

  The comb 10 includes a plurality of comb teeth 16 and a support shaft 14 that holds each comb tooth 16, and is attached to the cap portion 12 via the support shaft 14. The comb teeth 16 are attached in parallel to the support shaft 14, and spouts 17 are formed near the tips of the comb teeth 16 except for the upper and lower ends of the comb teeth 16. The spout 17 is open in a direction parallel to the axis of the support shaft 14 and communicates with a flow path 15 (see FIG. 3) formed inside the support shaft 14.

  As shown in FIG. 3, the cap portion 12 includes a cap body 18 and a valve 20, and is screwed into the mouth tube portion 8 by a female screw 13 formed on the inner surface of the cap body 18.

  The cap body 18 has a cylindrical shape, has an attachment portion 22 at the upper portion, and is formed with an anti-slip protrusion 19 and a mark 5 on the outer surface. The ridges 19 are formed in a plurality of vertical directions along the outer surface. The mark 5 is formed integrally with the cap body 18 at a position just below the comb teeth 16 and at substantially the same height as the protrusions 19.

  The attachment part 22 has a double structure of a truncated cone-shaped outer cylinder wall 23 and an inner cylinder wall 25, and the outer cylinder wall 23 and the inner cylinder wall 25 are connected at the upper part. As shown in FIG. 4, the outer cylinder wall 23 is formed with air inlets 3 in four directions, and the inside of the cap body 18 is conducted to the outside air. Further, the air introduction path 3 is formed on the side where the comb teeth 16 are attached at a position where it does not intersect with a plane passing through the central axis of each comb tooth 16. That is, it is formed so as not to be positioned below the comb teeth 16.

  For example, as shown in FIGS. 6 and 7, the air introduction path 3 has four protrusions 24 formed on the mold 21, and the cap 24 is injection-molded using the mold 21. It is formed through the outer wall 23.

  The inner cylinder wall 25 has a cylindrical shape, and the lower end of the support shaft 14 is fitted between the portions folded upward at the lower end, and the upper portion of the valve 20 is assembled to the portion extending downward.

  The valve 20 includes a valve body 26 and a holder 28 that holds the valve body 26, and has both functions of an air valve that controls the flow of air and a flow valve that controls the flow of content liquid. The valve body 26 is cylindrical and is made of a resin having elasticity. The valve body 26 has a ring-shaped valve film 28 on the upper outer periphery, and a disk-shaped valve film 27 on the lower inner side. The outer peripheral end of the valve membrane 28 is in contact with the outer periphery of the upper portion of the inner wall of the cap body 18, so that the valve membrane 28 can be ventilated only in the inflow direction from the inlet 3 into the cap body 18.

  The holder 30 has an outer cylinder 29 and an inner cylinder 31, the valve body 26 is assembled inside the inner cylinder 31, and the outer cylinder 29 is fitted inside the cap body 18. A cutout 33 is formed around the outer cylinder 29, and air flows through the cutout 33. The inner cylinder 31 has an outflow port 36 on the bottom wall, and the valve membrane 27 is in close contact with the outflow port 36 so as to be movable. Due to the valve membrane 27, the content liquid can flow through the outlet 36 only in the outflow direction to the outside of the cap body 18.

  The container body 6 is a delami bottle having an inner container 40 inside the outer container 38, and the outer container 38 and the inner container 40 are formed by blow molding using different resins.

  The outer container 38 has an elastic force that is appropriately deformed and restored when the body part is pressed, and a product name A consisting of letters, designs, etc. is printed on the front, and the left and right sides are shown in FIG. Such a non-slip portion 9 is formed by unevenness. The inner container 40 is integrally formed on the inner surface of the outer container 38 so as to be peelable from the outer container 38.

  A male screw 15 is formed on the outer periphery of the mouth tube portion 8, and a neck portion 11 having a diameter larger than that of the mouth tube portion 8 is formed at the lower portion of the mouth tube portion 8. The neck portion 11 is formed so that the lower inner surface of the cap body 18 is in airtight contact with the outer peripheral surface of the neck portion 11 when the comb cap 4 is securely screwed into the mouth tube portion 8.

  Further, the mouth tube portion 8 is formed with an air hole 39 that penetrates the mouth tube portion 8 in and out and communicates between the outer container 38 and the inner container 40. The upper portion of the air hole 39 is not formed with the thread of the male screw 15, and a flat portion 41 extending from the upper end of the mouth tube portion 8 to the air hole 8 is formed. With the flat portion 41, air flows into the air hole 39 from above the mouth tube portion 8 even when the comb cap 4 is screwed onto the male screw 15.

  Next, the operation of the comb-containing double container 2 will be described by taking as an example the case where the content liquid is a hair dyeing liquid for dyeing hair.

  The hair dyeing liquid is a mixed type in which an auxiliary agent is mixed with a main agent at the time of use. The main agent is accommodated in the container body 6 and is sealed by attaching a cap (not shown) to the mouth tube portion 8. The secondary agent is stored in a secondary agent container (not shown) different from the container main body 6, and is usually a container main body 6 storing the main agent, a cap 4 with a comb, and a container storing the secondary agent. Are distributed and sold as a set.

  A user who wants to dye hair first removes the cap of the container main body 6 and injects the auxiliary agent into the container main body 6 from the auxiliary agent container. Then, the main agent and the auxiliary agent are mixed in the container body 6 by tightening the cap again and shaking up and down.

  When the main agent and the auxiliary agent are sufficiently mixed, the cap is removed from the mouth tube portion 8, the female screw 13 is screwed into the male screw 15, and the comb cap 4 is assembled to the mouth tube portion 8 as shown in FIG.

  When the cap 4 with the comb is screwed into the mouth tube portion 8, the lower portion of the cap body 18 comes into contact with the neck portion 11 of the container body 6 and a little screwing force is applied. Since they do not match, the user feels that further screwing is necessary, and the comb cap 4 is rotated until the marks 5 and 7 coincide vertically. When the mark 5 and the mark 7 coincide with each other, the comb cap 4 can be securely assembled to the container body 6 and the user can confirm that the comb cap 4 has been screwed by the coincidence of the mark 5 and the mark 7.

  In such a state, the comb-equipped double container 2 has the comb teeth 16 accurately facing to the side of the product name A, and the comb teeth 16, the marks 5, the marks 7, and the non-slip portions 9 are vertically aligned. Be placed. Therefore, the user can obtain a very well-prepared impression from such an appearance.

  Furthermore, the comb-equipped cap 4 is securely assembled to the mouth tube portion 8 of the container body 6 in such a state, so that air does not leak from the neck portion 11 and the function as a delami bottle is ensured. Can demonstrate. That is, when the body portion of the container body 6 is pressed, the inner container 40 is pressed together with the outer container 38, and the hair dyeing liquid, which is the content liquid, pushes and opens the valve membrane 27 and flows out from the support shaft 14 through the passage and from the spout 17. Be poured out. When the pressure on the container body 6 is released, the return outlet 36 of the valve membrane 27 is closed and the outer container 38 is restored to force the valve membrane 27 through the valve membrane 28, the notch 33, and the air hole 39 from the introduction port 3. Air is introduced between 38 and the inner container 40.

  Then, when the container body 6 is pressed, the valve membrane 28 comes into close contact with the inner surface of the cap body 18 to stop the outflow of air, so that the pressing force is applied to the inner container 40 and the valve membrane 27 is actuated to open the outlet 36. The content liquid is poured out from the comb teeth 16. Thus, since the lower part of the cap 4 with a comb closely_contact | adheres to the neck part 11 and does not leak air from the lower part of the cap 4 with a comb, the function of a delami bottle act | operates appropriately and content liquid is poured out correctly.

  Further, since the air inlet 3 does not open below the comb teeth 16, even if the hair dyeing liquid travels along the support shaft 14 from the comb teeth 16 and flows down to the mounting portion 22, the air inlet 3 is blocked. Or entering the cap portion 12 from the air inlet 3 and stopping the operation of the valve 22. Therefore, when the force pressing the container body 6 is released, the container body 6 can be easily restored by the elastic force of the container body 6 and the next pouring can be performed without any trouble.

  Further, the double container 2 with a comb provides an appropriate anti-slip effect by the anti-slip portions 9 provided on the left and right sides, and presses the container body 6 so that the hair dyeing liquid as the content liquid is poured out from the spout 17. However, it is possible to comb the hair with the comb teeth 16 and attach the hair dyeing solution to the hair.

  In the above example, the content liquid is a hair dyeing liquid, but the present invention is not limited to the hair dyeing liquid. Although the container body 6 is a delami bottle, if it is a double container, it may not be a delami bottle in which the outer container 38 and the inner container 40 are integrally formed.
