Description

  The present invention relates to a squeeze container formed of a synthetic resin and having a double inner / outer structure. Here, the inner / outer double structure is an inner container and an outer container formed separately, and the inner container filled with the contents is assembled inside the outer container, or integrated in a laminated state. It is intended to include any of the delamination-type containers in which the contents are poured out by reducing the volume of the inner layer body filled with the contents and peeling it from the inner wall surface of the outer layer body. The one located inside is referred to as an inner layer body, and the one located outside is referred to as an outer layer body.

  The squeeze container that reduces the volume of the inner layer body by crushing the body part of the outer layer body and pours out the contents filled in the inner layer body is a hair dye, cosmetic, beverage, seasoning, drug (eye drops) In recent years, it has been widely used in a wide range of fields.

  This type of container is capable of efficiently reducing the volume of the inner layer body, that is, allowing the content to be efficiently poured out, and quickly restoring the collapsed outer layer body to its initial shape. In general, an introduction hole for introducing outside air (air) is provided between the inner layer body and the outer layer body in the side wall portion of the portion and the mouth-neck portion. Is provided with an introduction hole in the center of the front wall and / or rear wall of the outer wall of the body of the outer bottle, and when the body of the outer bottle is squeezed, the introduction hole is blocked by the user's finger. A delamination bottle has been proposed.

Japanese Patent No. 4975778

  By the way, the conventional delamination bottle disclosed in the above document is uncertain whether or not the user closes the introduction hole with his / her finger when the contents are poured out. If the usage pattern is such that the body portion of the outer layer bottle is crushed at a portion other than the air, the air interposed between the inner layer bag and the outer layer bottle escapes to the outside through the introduction hole. There was a concern that the inner layer bag could not be pressed efficiently.

  Further, in such a delamination bottle, the introduction hole is always exposed in the body portion, and it is inevitable that dust, dust, moisture, etc. enter from the introduction hole, and it cannot be said that it is hygienic. Met. As a measure for preventing the entry of dust, dust, etc., it is conceivable to cover the introduction hole with a label or a film. In this case, however, the position of the introduction hole becomes difficult to distinguish, and the introduction hole is subjected to squeeze deformation. There was a concern that it could not be reliably occluded.

  The subject of this invention exists in the place which proposes the squeeze container which can open and close the through-hole for external air introduction | transduction easily and can pour the contents efficiently, without exposing to the outer surface of a container.

  The present invention includes an outer layer body that has a spout, allows the body portion to be crushed and restored to its initial shape, and is disposed inside the outer layer body. A squeeze container provided with an inner layer body for pouring out the contents filled inside through the pouring stopper, wherein at least one through hole is provided in the body portion of the outer layer body, and the through hole is formed in the through hole. A valve member is arranged, and the valve member is integrally connected to a convex portion that is retained by the through-opening, and a base end portion of the convex portion, and the through-opening is disposed outside the body portion. A plate-like member concealed on the surface, and when the body portion of the outer layer body is crushed, the valve member is directly pressed to close the through hole, while the body portion of the outer layer body is closed to the initial shape. The through hole is opened when the inner layer body and the outer layer body are The squeeze container is characterized in that the tip of the convex part is a large diameter part, and a gap is provided between the outer layer body and the inner layer body around the tip part. .

  Further, the plate-like member has an annular seal portion that has an outer edge that is a free end, and surrounds the through-hole when the body portion of the outer layer body is crushed and closely contacts the outer surface of the body portion of the outer layer body. It is preferable to do this.

  The annular seal portion has a tapered shape toward the through-hole and has a seat portion that can be in close contact with the outer peripheral edge of the through-hole, and is provided between the center portion of the plate-like member and the outer edge thereof. It is possible to apply at least one rib formed or an annular peripheral wall integrally connected to the outer edge of the plate-like member.

  Furthermore, it is desirable to apply a plate-like member made of a soft material that can follow the crushing deformation when the body portion of the outer layer body is crushed.

  According to the squeeze container of the present invention having the above-described configuration, at least one through-hole is provided in the body portion of the outer layer body, and the through-hole is directly pressed when the outer layer body is crushed so as to pass through the through-hole. While the opening is closed, a valve member that opens the through-hole and introduces outside air between the inner layer body and the outer layer body when the outer layer body is restored to the initial shape is disposed. When pouring out, it becomes clear which position of the body part of the outer layer body should be pressed, the opening and closing of the through hole is facilitated, and the feel at the time of pressing becomes clear and the operability is improved. Further, since the through hole is covered with the valve member, it is possible to prevent intrusion of dust, dust, moisture, or the like (hygienic).

  Further, according to the squeeze container of the present invention, the valve member is held in the through hole so as to be prevented from coming off, and the outer surface of the squeeze container forms an outside air introduction path, and the base end of the convex portion Since the plate-like member that is integrally connected and covers the through hole is provided, the through hole can be opened and closed with a simple structure. Moreover, according to the squeeze container of the present invention, since the distal end portion of the convex portion is a large diameter portion, the convex portion of the valve member can be retained and retained in the through hole, and the periphery of the distal end portion is By providing a gap between the outer layer body and the inner layer body, air can be reliably introduced between the outer layer body and the inner layer body through the through hole.

  In addition, according to the squeeze container of the present invention, the outer edge of the plate-like member is a free end, and the inner peripheral wall portion of the plate-like member surrounds the through-hole when the body portion of the outer layer body is crushed. Since the annular seal portion that is in close contact with the outer surface of the body portion of the outer layer body is provided, air interposed between the inner layer body and the outer layer body escapes to the outside when the body portion (valve member) is pressed. Can be prevented or hindered, and the content can be efficiently dispensed.

  Furthermore, according to the squeeze container of the present invention, since the plate-like member is made of a soft material that can follow the deformation when the body portion of the outer layer body is crushed, the opening and closing operation of the through hole is easy to perform.

It is the figure which showed typically the embodiment of the squeeze container according to this invention about the cross section. It is the figure which showed the use condition of the squeeze container shown in FIG. 1 about the valve member. (A) (b) is the figure which showed other embodiment of the squeeze container according to this invention about the valve member. (A) (b) is the figure which showed typically the cross section of the modification of the through-hole provided in the trunk | drum part of the outer layer body with the valve member shown in FIG. (A) (b) is the figure which showed other embodiment of the squeeze container according to this invention about the valve member.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is a diagram schematically showing a cross section of an embodiment of a squeeze container according to the present invention.

  Reference numeral 1 in the figure is an outer layer body made of a synthetic resin capable of being pressed and deformed (squeezed) and forming the outer shape of the container. This outer layer body 1 allows the body portion 1a to be crushed and restored to its initial shape, and has a cylindrical mouth and neck portion 1b at the top of the body portion 1a.

  The shape of the trunk portion 1a can be changed as appropriate according to the type and use of the contents to be filled. Here, the overall shape of the outer layer body 1 is not displayed. In addition, the shape of the mouth-and-neck portion 1b is not limited to a cylindrical shape, and various shapes can be employed.

  Reference numeral 2 denotes a spout plug attached to the mouth / neck portion 1 b of the outer layer body 1. The spout tap 2 is integrally connected to the top wall 2a covering the opening of the neck 1b of the outer layer body 1 and the edge of the top wall 2a, and can be undercut fitted on the outer periphery of the neck 1b (even by screw engagement). A good annular peripheral wall 2b, and a pour cylinder 2c which is provided on the top wall 2a and forms a pour route for the contents.

  Reference numeral 3 denotes a check valve which is integrally connected to the lower end of the dispensing cylinder 2c and held down. The check valve 3 includes a cylindrical body 3a having a passage connected to the extraction path of the extraction cylinder 2c, and a ball 3b movable in the passage of the cylindrical body 3a.

The check valve 3, the outer layer of the ball 3b, be one that opens the pouring path of the pouring cylinder 2c by moving toward the upper end 3a ₁ of the cylindrical body 3a, in the open state of the pouring path By crushing the body portion 1a of the body 1, the contents can be poured out (the contents flow through the gap between the ball 3b and the cylinder 3a to the pouring path of the pouring cylinder 2c).

To move towards the ball 3b of the check valve 3 to the cylindrical body 3a upper end 3a ₁ of may be pressed body portion 1a of the outer member 1 holding the squeeze container tilting posture or inverted posture, This increases the internal pressure of the inner member, balls 3b are moved toward the upper end 3a ₁ of the cylindrical body 3a by its own weight or the like of the pressure and the ball 3b itself. On the other hand, in order to move the ball 3b toward the valve seat 3c, the pressing force applied to the body portion 1a of the outer layer body 1 is released and the squeeze container is returned to the normal posture. Then, the outer body 1, the restoring force of the inner layer body following the restoration deformation to the initial shape by (pressure change) and its own weight of the ball 3b, the ball 3b is moved toward the lower end 3a ₂ of the cylindrical body 3a . When the ball 3b comes into contact with the seat 3c, the dispensing path of the dispensing cylinder 2c is blocked.

Incidentally, the check valve 3, when the ball 3b is moved toward the seat 3c provided at the lower portion 3a ₂ of the cylindrical body 3a, the contents remaining in the dispensing path of the pouring cylinder 2c is It has a function (suck back function) to be drawn inside the cylinder 3a, thereby preventing dripping.

  For the spigot 2, it is not essential to install a check valve 3 having a suck back function, and a reverse structure having a structure that is appropriately different depending on the type and application of the contents such as a well-known one-point valve or three-point valve. A stop valve can also be applied, and is not limited to the illustrated one.

  Reference numeral 4 denotes an inner layer body (made of a synthetic resin or the like) that is disposed on the inner side of the outer layer body 1 and can be fixed on the inner peripheral wall of the mouth-neck portion 1b of the outer layer body 1, for example. The inner layer body 4 is reduced in volume by crushing the outer layer body 1, and the contents filled inside can be poured out through the spout 2.

  Reference numeral 5 denotes a through hole provided in the body portion 1 a of the outer layer body 1 and leads to the outer surface of the inner layer body 4, and 6 denotes a valve member attached to the through hole 5.

  When the outer layer body 1 is crushed, the valve member 6 directly presses the outer hole body 1 to close the through-hole 5, but the outer layer body 1 is restored to the initial shape of the body portion 1 a (the initial state in which no pressing force is applied). The through-hole 5 is opened to introduce the outside air between the inner layer body 4 and the outer layer body 1.

  Specifically, the valve member 6 is held by the through-hole 5 so as to be prevented from coming off, and has a convex portion 6b that forms an outside air introduction path 6a on its outer surface, and a base end portion 6c of the convex portion 6b. What is comprised by the plate-shaped member 6d which connects integrally and covers this through-hole 5 is applied.

  The tip portion 6 h of the convex portion 6 b has a large diameter portion, and the large diameter portion is inserted into the space between the outer layer body 1 and the inner layer body 4, so that the convex portion 6 b becomes the outer layer body 1. Is retained. The introduction path 6 a is provided on the outer surface of the convex portion 6 b and is formed by one or more grooves that communicate the inner side and the outer side of the outer layer body 1.

  Both the pressing part connected to the convex part 6b and the cover part connected to the pressing part of the plate-like member 6d are appropriately adjusted to a thickness that can be elastically deformed. In particular, the cover part and the through-opening 5 A gap t is formed between the outer surface of the body portion 1a in the periphery. Note that the gap t may be omitted if the flow path of the outside air (air) can be formed by providing a groove, a through hole, or the like on the inner peripheral surface of the plate-like member 6d. Further, the thickness of the plate-like member 6d can be changed as appropriate.

  As the plate-like member 6d, it is possible to apply a circular member made of a soft material such as polyethylene, which can follow the deformation of the body portion 1a of the outer layer body 1, and its outer edge is a free end. It has become. The inner wall surface is in close contact with the outer peripheral edge of the through hole 5 when the body portion 1a of the outer layer body 1 is crushed at the connection portion (the base end portion 6c of the convex portion 6b) with the convex portion 6b. Thus, the through-opening 5 is closed, but when the outer layer body 1 is restored to the initial shape (or set), the through-opening 5 is opened away from the outer peripheral edge of the through-opening 5. A seal portion 6e is formed. As the annular seal portion 6 e, one having a tapered seat portion that is tapered toward the through hole 5 can be applied.

  The plate-like member 6d can be a circular shape as shown by the imaginary line in FIG. 1, but the shape can be variously changed and is not limited to the illustrated one.

  Reference numeral 7 denotes an annular peripheral wall that is integrally connected around the outer edge of the plate-like member 6. The annular peripheral wall 7 is provided with one or more cutouts 7a for circulating outside air. The end of the annular peripheral wall 7 is always in contact with the outer surface of the body portion 1a of the outer layer body 1 regardless of when the outer layer body 1 is crushed or restored, thereby securing a gap t.

  Reference numeral 8 denotes a lid that is held on the pouring tap 2 through a hinge h so as to be openable and detachable at the corner where the annular peripheral wall 2b and the top wall 2a intersect. The lid 8 has a storage space for the dispensing cylinder 2c formed inside thereof, and the back surface of the top plate accommodates the dispensing cylinder 2c therein (closed state of the lid 8). Thus, a sealed cylinder 8a that can be fitted into the extraction path of the extraction cylinder 2c is provided.

  In order to pour out the contents in the inner layer body 4 in the squeeze container having such a configuration, first, the squeeze container itself should be held in an inclined position so that the lid 8 is opened and the spout 2 is directed downward. Hold in inverted position.

  The valve member 6, preferably the pressing portion (the portion where the convex portion 6b is located) is pressed to push the plate-like member 6d to crush the body portion 1a of the outer layer body 1, and this crushing The contents filled in the inner layer body 4 are poured out through the dispensing path of the dispensing cylinder 2c.

  By pushing the valve member 6, the inner layer body can be pushed inward in the radial direction at the front end portion 6h of the convex portion 6b, and volume reduction of the inner layer body 4 by pushing the inner layer body 4 directly by the convex portion 6b. Effects such as triggering deformation and securing an outside air introduction path can be obtained. Further, even in the initial state (restored state), the distal end portion 6h is appropriately large so that a gap is formed around the distal end portion 6h of the convex portion 6b, that is, between the outer layer body 1 and the inner layer body 4. It can be set as a diameter part. In addition, it can also be set as the structure which the front-end | tip part 6h of the convex-shaped part 6b does not push the inner-layer body 4 directly.

  In the squeeze container according to the present invention, when the body portion 1a of the outer layer body 1 is crushed, as shown in FIG. 2, the annular seal portion 6e is brought into close contact with the outer peripheral edge of the through-hole 5, whereby the outer layer body Since the air existing between 1 and the inner layer body 4 does not escape to the outside, the pressing force applied to the crushing acts effectively on the inner layer body 4, and the contents are efficiently poured out. . Even though the through-hole 5 may not be completely closed, the air flow is inhibited by the valve member 6, so that the air intervening between the inner layer body 4 and the outer layer body 1 is extremely difficult to escape. It becomes small and the content can be efficiently poured out.

  A plurality of convex portions can be formed on the outer surface (pressing surface) of the plate-like member 6d, and visual and tactile effects can be obtained by the convex portions, and the user can make a mistake in the pressing position. The plate-like member 6d can be reliably operated.

  When the content is poured out and the pressing force applied to the body portion 1a of the outer layer body 1 is crushed, as shown in the enlarged view of FIG. 1, the cutout portion 7a, the gap t, and the through hole of the annular peripheral wall 7 5, outside air is introduced between the outer layer body 1 and the inner layer body 4, and the outer layer body 1 crushed and deformed by the squeeze is quickly restored to the initial shape.

  FIGS. 3A and 3B are diagrams schematically showing another embodiment of the squeeze container according to the present invention with respect to the valve member 6.

  The valve member 6 has a dome-like cross-sectional shape in which the central portion of the plate-like member 6d protrudes most outward in the radial direction of the body portion 1a of the outer layer body 1, and forms a gap t on the inside thereof. At the same time, the outer edge is closely attached to the outer surface of the body portion 1 a of the outer layer body 1.

  The valve member 6 having such a structure is provided with an annular seal portion (rib) 6f between the inner surface of the plate-like member 6d, in particular, from the center portion to the outer edge end, and external air is given to the outer edge end. At least one notch 9 to be introduced is formed.

  When the body portion 1a of the outer layer body 1 is restored (including the initial state), the valve member 6 has the outer layer body 1 through the notch 9, the gap t, and the introduction path 6a as shown in FIG. Can be introduced between the inner layer body 4 and the inner layer body 4. On the other hand, when the body portion 1a of the outer layer body 1 is crushed, the outer surface of the body portion 1a of the outer layer body 1 is surrounded by the annular seal portion 6f so as to surround the through hole 5 as shown in FIG. The through-hole 5 is closed in close contact with each other to prevent escape of air interposed between the outer layer body 1 and the inner layer body 4.

  When the annular seal portion 6f is in close contact with the outer surface of the body portion 1a of the outer layer body 1, the outer peripheral edge of the through hole 5 can be simultaneously in close contact with the inner wall surface of the plate-like member 6d. Since the heavy seal structure is configured, the through-opening 5 can be more reliably closed.

  In particular, when the annular seal portion 6f is provided, for example, even if the position to which the finger is applied does not exist in the pressing portion, that is, the central portion of the plate-like member 6d, the annular seal portion 6f is the trunk portion of the outer layer body 1. As long as it adheres to the outer surface of 1a, it has the advantage that the through-hole 5 can be closed. In this structure, a plurality of annular seal portions 6f may be provided concentrically. Moreover, the annular seal part 6e can also be used together.

  As for the through-opening 5, the outer peripheral edge of the through-opening 5 is shown as an example in which the outer peripheral edge is shaped to protrude outward in the radial direction of the body portion 1 a. As shown in FIG. 4, a flat one, or as shown in FIG. 4B, one having a shape protruding toward the radially inner side of the body portion 1a, or a concave portion recessed in the radially inner side of the body portion 1a (see FIG. (Not shown), and the through-hole 5 may be formed on the bottom surface of the recess, and this point is not limited.

  Next, FIGS. 5A and 5B schematically show still another embodiment of the squeeze container according to the present invention with respect to the valve member 6.

  In this example, the annular peripheral wall 7 is not provided with the notch portion 7a (see FIG. 2), and the annular peripheral wall 7 itself functions as the annular seal portion 6g.

As shown in FIG. 5A, the valve member 6 has a gap t between the annular seal portion 6g and the outer surface of the body portion 1a of the outer layer body 1 when the body portion 1a of the outer layer body 1 is restored. A connecting gap t ₁ is formed, and when the body portion 1 a of the outer layer body 1 is crushed, an annular seal portion 6 g is formed on the outer surface of the body portion 1 a of the outer layer body 1 as shown in FIG. The through hole 5 is closed by close contact.

  Even in the valve member 6 having such a structure, the through-hole 5 can be easily closed by the annular seal portion 6g being in close contact with the outer surface of the body portion 1a of the outer layer body 1.

Incidentally, the plate-like member 6d of the valve member 6, the clearance t ₁ is securely formed at the time of restoration of the body portion 1a of the outer layer body 1, and the crushed deformation during crushing of the body portion 1a of the outer member 1 It is important to consider the thickness, shape, and material (polypropylene, etc.) so that it can be easily followed. However, the plate-like member 6d may be configured not to follow the crushing deformation when the body portion 1a of the outer layer body 1 is crushed.

  In the squeeze container in which the outer layer body 1 is formed in a cylindrical shape, the valve member 6 is preferably shaped along the outer surface of the body portion 1a of the outer layer body 1, but in particular, as shown above 3 (a) (b) and 5 (a) and 5 (b), the body portion 1a to which the valve member 6 is attached is partially flattened locally. According to this, when the body portion 1a of the outer layer body 1 is crushed, the entire annular seal portions 6f and 6g can be securely adhered to the outer surface of the body portion 1a. Even if the valve member 6 may not completely close the through hole 5, the valve member 6 itself can inhibit the air flow, so the inner layer body 4 and the outer layer body 1. The air intervening between them does not easily escape to the outside, and is almost the same as the case of completely closing the through hole 5 in that the contents can be efficiently poured out.

  The through-opening 5 and the valve member 6 are shown as an example provided in the body portion 1a of the outer layer body 1. However, the through-opening 5 and the valve member 6 are provided at the opposite positions, such as through-opening. A plurality of holes 5 and valve members 6 may be provided.

  ADVANTAGE OF THE INVENTION According to this invention, the squeeze container which can be opened and closed reliably, without exposing the through-hole for external air introduction provided in the trunk | drum part of an outer-layer body to the outer surface of a container can be provided.
