Description

Technical Field

[0001] The present invention relates to a discharge container, and more particularly to a discharge container capable of measuring a relatively high-viscosity content in a simple manner and discharging a fixed quantity.

Background Art

[0002] Conventionally, a pouch container or a tube container has been used as a container body for storing a relatively high-viscosity content having fluidity such as a paste or gel form, such as cosmetics and seasonings. In a conventional tube container, when an aspirating device such as a pump is to be attached to the mouthpiece portion for discharging a fixed quantity, it has been difficult to aspirate and measure a fixed quantity.

[0003] For this reason, as a discharger provided in a container body that discharges the content from the mouth when pressed, a flexible cylindrical portion that communicates with the mouth and has an internal space capable of storing a predetermined amount of the content, and a discharge portion that discharges the content stored in this internal space to the outside, and a check valve that opens and closes the communication path between the mouth and the cylindrical portion and allows the movement of the content only in the direction from the container body toward the cylindrical portion when the communication path is opened. It has been conventionally known that by setting the volume of the internal space of the cylindrical portion to an amount corresponding to the amount of one use of the content and pressing the cylindrical portion, the content of one use amount can be discharged from the discharge portion (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, with respect to the discharge container described in Patent Document 1 above, if the cylindrical portion is pressed, the content for one use amount can be discharged from the discharge portion. However, after the pressing operation, the remaining amount in the cylindrical portion is difficult to be constant, so there is a problem that the operability is not good.

[0006] An object of the present invention is to solve the above problems, and to provide a discharge container having good operability during use, further capable of easily discharging the content continuously by continuously squeezing the container body, and also capable of discharging the content in a fixed amount.

Means for Solving the Problems

[0007] In order to solve the above problems, the present invention provides, as a discharge container, a container body for storing a content, a metering stopper attached to the mouth cylinder portion of the container body, a check valve provided between the container body and the metering stopper and allowing only the movement of the content from the container body toward the metering stopper, and an overcap covering the metering stopper and attached to the mouth cylinder portion. The metering stopper includes a bellows-shaped expandable and contractible peripheral wall that is attached to the mouth cylinder portion and can expand and contract in the axial direction, and a discharge head that extends axially from the upper end of the expandable and contractible peripheral wall and has a discharge port opened at the tip. After squeezing the container body and filling the content into the metering stopper, by compressing the expandable and contractible peripheral wall of the metering stopper, a fixed amount of the content is discharged from the discharge port of the discharge head. A configuration characterized by this is adopted.

[0008] As an embodiment of the discharge container, the overcap covers the outer periphery of the metering stopper, and has a peripheral wall portion whose inner periphery is screwed onto the outer periphery of the mouth cylinder portion of the container body, and extends inward from the upper end of the peripheral wall portion, and the lower surface abuts against the upper surface of the discharge head to close the discharge port And a top wall portion, and the discharge head is provided with a discharge peripheral wall erected from the upper end of the expandable and contractible peripheral wall, a top wall extending inward from the upper end of the discharge peripheral wall and having a discharge port opened at the center, and a discharge peripheral wall protruding radially from the outer periphery thereof And an operation piece for expanding and contracting the expandable and contractible peripheral wall. The container body is formed on the inner periphery of the mouth cylinder portion and has a partition portion that closes the inner side and an opening portion opened in the partition portion. The check valve is sandwiched between the partition portion of the container body and the metering stopper and fixed in the mouth cylinder portion And a mounting peripheral wall, and a valve body that is continuously provided at the lower end of the inner periphery of the mounting peripheral wall and whose lower surface abuts against the upper surface of the partition portion to close the opening portion.

Advantages of the Invention

[0009] By adopting the above configuration, the discharge container of the present invention, during use, expands and contracts axially to make the remaining amount in the metering stopper constant, so that the operability is good. Furthermore, by continuously squeezing the container body, the content can be continuously discharged easily, and the content can also be filled from the container body into the metering stopper for quantitative discharge.

Modes for Carrying Out the Invention

[0011] Next, embodiments of the discharge container of the present invention will be described with reference to examples and the drawings. In the following description, with reference to FIG. 1, the vertical direction is defined as the "axial direction", the upward direction is defined as "up", the downward direction is defined as "down", and the left-right direction is defined as the "radial direction".

[0012] (Example) In FIG. 1, A is a tube container which is a container body for containing the content, B is a metering stopper attached to the mouth tube portion 1 of the tube container A, C is a check valve which is attached in the mouth tube portion 1 of the tube container A and is provided between the tube container A and the metering stopper B and allows only the movement of the content from the tube container A toward the metering stopper B, and D is an overcap which covers the metering stopper B and is attached to the mouth tube portion 1.

[0013] As shown in FIGS. 1 and 2, the tube container A includes a cylindrical mouth tube portion 1, a shoulder portion 2 formed in a conical shape with a gradually increasing diameter from the lower end of the mouth tube portion 1, a cylindrical elastic squeezable body portion 3 vertically provided from the lower end of the shoulder portion 2, and a bottom portion 4 formed at the lower end of the body portion 3 and sealed after filling the content. On the outer periphery of the mouth tube portion 1, a mounting outer peripheral portion 5 for mounting the metering stopper B at the upper end is formed, a male screw portion 6 for screwing the overcap D is provided below the mounting outer peripheral portion 5, a partition portion 7 for closing the inside of the mouth tube portion 1 is formed at the lower inner periphery, and an opening 8 penetrating vertically is opened at the center of the partition portion 7.

[0014] As shown in FIGS. 1 and 2, the metering stopper B includes an outer cylinder portion 10 whose inner periphery engages with the mounting outer peripheral portion 5 of the mouth tube portion 1, a ring-shaped upper wall portion 11 extending inward from the upper inner edge of the outer cylinder portion 10 and having the upper end surface of the mouth tube portion 1 in close contact with the lower surface, an inner cylinder portion 12 vertically provided at the inner edge of the upper wall portion 11 and having the outer periphery in close contact with the upper inner periphery of the mouth tube portion 1, a bellows-shaped expandable and contractible peripheral wall 13 extending upward from the inner edge of the upper wall portion 11 and being axially expandable and contractible, a cylindrical discharge peripheral wall 14 erected from the upper end of the expandable and contractible peripheral wall 13, a ring-shaped top wall 16 extending inward from the upper end of the discharge peripheral wall 14 and having a discharge port 15 opened at the center, and a flange-shaped operation piece 17 protruding radially outward from the lower outer periphery of the discharge peripheral wall 14 and expanding and contracting the expandable and contractible peripheral wall 13. In this embodiment, the outer cylinder part 10, the upper wall part 11, and the inner cylinder part 12 function as the mounting part, the discharge peripheral wall 14, the discharge port 15, the top wall 16, and the operation piece 17 constitute the discharge head 18, and the discharge head 18 extends axially from the upper end of the telescopic peripheral wall 13, and the discharge port 15 is opened at the center of the tip.

[0015] As shown in FIGS. 1 and 2, the check valve C has a mounting peripheral wall 20 whose outer periphery is inserted into the inner periphery of the mouth cylinder part 1, the upper end abuts against the lower end of the inner cylinder part 12 of the metering stopper B, and the lower end abuts against the upper surface of the partition wall part 7 in the mouth cylinder part 1, and a valve body 21 which is continuously provided at the lower end of the inner periphery of the mounting peripheral wall 20, the lower surface abuts against the upper surface of the partition wall part 7 to close the opening 8, and is a one-way valve that opens the opening 8 by the content extruded from the tube container A as shown in FIG. 3.

[0016] As shown in FIGS. 1 and 2, the overcap D includes an inner cap part 25 that covers the metering stopper B and is mounted on the outer periphery of the mouth cylinder part 1 of the tube container A, and an outer wall part 26 that is continuously provided so as to surround the outer periphery of the inner cap part 25 and is designed to be continuous from the outer periphery of the body part 3 of the tube container A. The inner cap part 25 includes a peripheral wall part 28 that covers the outer periphery of the metering stopper B and is mounted on the outer periphery of the mouth cylinder part 1 of the tube container A, and a top wall part 29 that extends inward from the upper end of the inner periphery of the peripheral wall part 28, and the lower surface is formed to abut against the upper surface of the top wall 16 of the discharge head 18 of the metering stopper B to close the discharge port 15. A female screw part 30 that is screwed with the male screw part 6 on the outer periphery of the mouth cylinder part 1 is screwed on the lower part of the inner periphery of the peripheral wall part 28.

[0017] Next, the usage mode and working effects of this embodiment will be described. For the discharge container of this embodiment, first, after inserting the check valve C into the mouth cylinder part 1 of the tube container A, the metering stopper B is mounted on the upper part of the mouth cylinder part 1. At this time, the mounting peripheral wall 20 of the check valve C is sandwiched between the upper surface of the partition wall part 7 of the tube container A and the lower end surface of the inner cylinder part 12 of the metering stopper B, and is fixed in the mouth cylinder part 1. At the same time, the valve body 21 of the check valve C abuts against the upper surface of the partition wall part 7 to close the opening 8. In addition, a metering chamber α is formed between the inside of the metering stopper B and the inside of the mounting peripheral wall 20 of the check valve C.

[0018] Next, the overcap D is screwed onto the mouth cylinder portion 1 of the tube container A, and as shown in FIG. 1, a closed discharge container is assembled. At that time, in order to seal the inside of the metering stopper B, a seal s is adhered to the upper surface of the top wall 16, closing the discharge port 15. In addition, although not shown, in order to prevent unauthorized opening before use, a shrink label or the like may be provided between the tube container A and the overcap D in the discharge container of this embodiment.

[0019] After the discharge container is assembled, the contents are filled from the bottom 4 of the tube container A, and by sealing the bottom 4, the discharge container with the contents filled in the body portion 3 of the tube container A is obtained. As the contents, it is possible to accommodate those with relatively high viscosity such as wasabi and mustard, or those in which solid substances of grated ingredients are mixed and the overall viscosity becomes relatively high.

[0020] To use the contents in the tube container A, first, grasp the outer wall portion 26 of the overcap D with a finger and rotate the overcap D in the opening direction with respect to the mouth cylinder portion 1. After opening the overcap D, peel off the seal s adhered to the upper surface of the top wall 16 of the discharge head 18 of the metering stopper B and open the discharge port 15 of the discharge head 18.

[0021] Next, as shown in FIG. 3, tilt the top wall 16 of the metering stopper B downward, squeeze the body portion 3 of the tube container A, and apply pressure to the inside of the tube container A. Then, the pressurized contents push open the valve body 21 of the check valve C through the opening 8 of the partition wall portion 7 of the mouth cylinder portion 1, releasing the opening 8 of the partition wall portion 7, and the contents are pushed into the metering stopper B.

[0022] When using without measuring the contents, if the body 3 of the tube container A is continuously squeezed, the contents extruded into the measuring stopper B during measurement will be discharged to the outside from the discharge port 15 opened in the discharge head 18 of the measuring stopper B. In this way, by continuously squeezing the body 3 of the tube container A, the contents can be continuously discharged from the discharge port 15 of the measuring stopper B.

[0023] On the other hand, when using after measuring the contents, when the contents are completely filled in the measuring stopper B and just before overflowing from the discharge port 15, if the squeezing of the body 3 of the tube container A is released, since the body 3 tries to return from the squeezed state, it tries to draw the contents back into the tube container A from the opening 8. However, the valve body 21 of the check valve C is quickly drawn back together with the contents, closing the opening 8 of the partition wall portion 7, so the contents remain filled in the measuring stopper B. Note that the measuring stopper B is preferably made transparent or translucent so that the filling state of the contents can be easily visually recognized from the outside.

[0024] As shown in FIG. 4, with the contents filled in the measuring stopper B, when a finger is placed on the operation piece 17 of the discharge head 18 and the bellows-shaped expandable and contractible peripheral wall 13 is crushed so as to be axially compressed, the inside of the measuring stopper B becomes a measuring chamber β with a reduced volume of the measuring chamber α. At that time, since the valve body 21 closes the opening 8, the contents in the measuring stopper B are not returned to the tube container A, so an amount of contents corresponding to the volume of the measuring chamber α - the volume of the measuring chamber β is discharged to the outside from the discharge port 15 of the discharge head 18. In the discharge container of this embodiment, by reducing the volume of the measuring stopper B, the contents can be simply measured by a fixed amount and discharged to the outside from the discharge port 15.

[0025] Next, when the discharge from the discharge port 15 is completed and the finger is removed from the operation piece 17, due to the elastic force of the expandable and contractible peripheral wall 13, the volume reduction of the measuring stopper B is released, outside air is sucked into the measuring stopper B from the discharge port 15, and the measuring stopper B returns to its original state.

[0026] Again, squeeze the body portion 3 of the tube container A to apply internal pressure into the tube container A. After filling the contents into the measuring chamber α, place a finger on the operating piece 17 of the discharge head 18 of the measuring stopper B, and repeat the compression of the expandable and contractible peripheral wall 13, so that a set fixed amount of the contents can be continuously discharged.

[0027] When the use of the contents is finished, screw the overcap D onto the mouth cylinder portion 1 of the tube container A and close the lid. As shown in FIG. 1, the inner cap portion 25 covers the outer periphery of the measuring stopper B, and the lower surface of the top wall portion 29 abuts against the upper surface of the top wall 16 of the discharge head 18 of the measuring stopper B to close the discharge port 15. At the same time, the inner periphery of the lower part of the peripheral wall portion 28 is screwed onto the outer periphery of the mouth cylinder portion 1, so that the inside of the measuring stopper B can be sealed.

Industrial Applicability

[0028] During use, the discharge container of the present invention expands and contracts in the axial direction to make the remaining amount in the measuring stopper constant, resulting in good operability. Furthermore, by continuously squeezing the container body, it is easy to continuously discharge the contents, and it is also possible to fill the contents from the container body into the measuring stopper for quantitative discharge. Therefore, as the contents, it is suitable as a discharge container for accommodating various food seasonings, cosmetics, drugs, etc. with relatively high viscosities, or substances in which solids are mixed and the overall viscosity is relatively high.
