Description

  The present invention relates to a paste toothpaste pump container and an oral product that can stably store contents and can be easily taken out.

  A tube container such as a laminate tube or an aluminum tube is generally used as a paste-like toothpaste, that is, a toothpaste container. These tube containers have a mechanism in which the contents are discharged from the container mouth when the user manually applies a compressive force to the main body, but the amount used for one brushing is affected by the degree of the compressive force. For this reason, the amount of use differs for each person who uses it, and even if it is the same user, it will become a different amount for every use. It is important that dentifrices, especially quasi-drugs and toothpastes of pharmaceuticals, contain medicinal ingredients, and it is important that the effective amount be applied to the oral cavity. It is difficult to adjust evenly, and if the amount of dentifrice is small, a sufficient effective amount is not used for dentifrice. Conversely, if the amount of dentifrice is large, more than the effective amount is applied. There was a problem of lack of economic efficiency.

  The pump container has an advantage that a uniform amount is discharged by one pushing operation, and the problem that the one-time amount is not uniform as described above can be solved. However, even if paste-like toothpaste is placed in a general-purpose pump container such as a shampoo, the toothpaste has properties such as adhesiveness, viscosity, and high powder content. However, it does not fall down due to gravity alone, and a large amount of residual medicine is generated without being able to inhale from the pump suction port, which is uneconomical. Therefore, there is a current situation that a pump container is difficult to use as a paste-like toothpaste container.

  For example, the following are disclosed as pump containers (Patent Documents 1 to 3). However, there is no description about a paste-like toothpaste container, and it is not designed about a pump container suitable for paste-like toothpaste.

International Publication WO93 / 25319 Pamphlet JP-A-5-310265 JP-A-10-323590

  It is an object of the present invention to propose a pump container that can store paste-like toothbrushes well, and does not make the amount used per time non-uniform depending on the user, and that can discharge a medicine by a simple operation.

  As a result of intensive studies, the present inventor has found that a good pump container can be created as a paste-like toothpaste container by using a laminated bottle as a pump container and making the nozzle discharge port of the pump dispenser have a specific cross-sectional area. The inventor completed the pump container of the present invention. Furthermore, it discovered that the oral cavity product which a user can discharge easily was made by putting paste-like toothpaste of specific viscosity in the pump container of this invention, and completed this invention.

The present invention is as follows.
[Claim 1]
A delamination bottle that is composed of at least two layers of an inflexible outer layer and a flexible inner layer, has a mouth portion at the top, and stands upright;
A paste toothpaste pump container comprising a pump dispenser having a cross-sectional area of a nozzle discharge port of 5 to 10 mm ² .
[Section 2]
Pump dispenser
The tip of the pump suction port is located between about 1/10 to 3 from the bottom in the depth direction with respect to the length from the shoulder of the bottle to the bottom, and the cylinder internal volume when the spring is extended and when the spring is contracted Item 2. The paste toothpaste pump container according to Item 1, wherein the difference from the cylinder internal volume is 0.1 to 1 cm ³ .
[Section 3]
Item 3. The paste toothpaste pump container according to Item 1 or 2, wherein the pump dispenser further places a metal ball valve in the discharge passage inside the discharge pipe.
[Claim 4]
Item 4. The paste toothpaste pump container according to any one of Items 1 to 3, wherein the pump pressure is 9 to 25N.
[Section 5]
In the pace-like toothpaste pump container according to any one of Items 1 to 4,
An oral product characterized by containing a paste-like toothpaste having a viscosity of 1 to 60 Pa · S.

According to the paste toothpaste pump container of the present invention, the contents can be stored stably, the amount used per time can be made uniform, and the user can easily take out the contents. That is, the delamination bottle makes it difficult for the contents to come into contact with air, so that oxidation can be prevented. In addition, the container discharge port blocks the contact of the air with the outside due to the placed metallic sphere, and drying near the outlet of the contents and deterioration of the active ingredient can be prevented. Since the pump suction port is located between approximately 1/10 and 3 from the bottom, the content can be smoothly discharged from the pump, and the remaining content at the end of use can be reduced. By making the internal volume difference of the syringe from 0.1 to 1 cm ³ , the amount used per time can be made uniform while making the amount effective as a dentifrice. Also, by setting the pump pressure to 9 to 25 N, the contents can be discharged without requiring excessive force by operating one finger. It can facilitate discharge of the toothbrush by the cross-sectional area of the discharge port 5 to 10 mm ^2.

  According to the oral product of the present invention, a paste-like toothpaste having a viscosity of 1 to 60 Pa · S is placed in the pump container of the present invention, so that it can be easily discharged from the pump and has a shape retaining property on a toothbrush. be able to.

  The paste toothpaste pump container of the present invention will be described with reference to the drawings. 1 to 3 are sectional views of an embodiment of the pump container of the present invention. Except for the features of the present invention, known pump dispensers and bottle containers can be used.

  The pump container 1 includes a bottle part 2 and a pump dispenser part 3. The bottle part 2 is filled with a dentifrice 4. The bottle part is mainly composed of two layers, and the outer layer is made of polyethylene resin and is inflexible. The inner layer is made of nylon whose inner surface is coated with a resin for protecting the dentifrice, and is flexible. The inner layer of nylon peels off from the outer layer as the pump is used, and has a delaminating structure that contracts as the content of the dentifrice decreases. For this reason, the dentifrice does not come into contact with air in the bottle. Further, it is possible to prevent a problem that the dentifrice does not reach the pump suction port 5 due to adhesion to the inner wall of the bottle, and the remaining amount of the dentifrice can be reduced. Furthermore, the outer layer and a part of the inner layer can be adhered using the technique disclosed in JP-A-5-310265, and the inner layer can be contracted cleanly. When the inner layer contracts, air can be taken into the space between the inner layer and the outer layer from the outer air groove formed in the lower portion, and the toothpaste can be discharged smoothly. A screw thread 6 for screwing the pump dispenser is formed on the upper part of the bottle part, and a bottle mouth part 7 is formed in the center. The suction port tip of the suction pipe attached to the pump dispenser is configured between 1/10 and 3 from the bottom with respect to the length La from the upper shoulder to the bottom in the bottle depth direction. That is, in FIG. 1, La: Lb = 10: 1 to 3 is adjusted. By using this position, the dentifrice can be smoothly discharged to the pump inlet. In other words, the dentifrice sinks in the lower part due to gravity and the compressive force of the inner layer, and the dentifrice stored on the bottom surface has a pump inlet near it, so the dentifrice can also be inhaled by manual pump suction input . Moreover, since it is not in contact with the lowermost part of the inner layer, the inner surface of the inner layer is in close contact with the pump suction port, and there is no problem that the suction of the dentifrice is prevented.

  The pump dispenser unit 3 includes a pump head 11, a bottle cap 12, a piston unit 13, a cylinder 14, and a suction pipe 15. The cylinder 14 enters the inside of the bottle from the bottle upper opening. A suction pipe 15 is connected to the lower end opening of the cylinder 14. The upper part of the cylinder has a ring shape and is fitted in the bottle cap and the opening portion inside the bottle cap. A packing 19 for connecting to the bottle is attached to the lower part of the ring of the cylinder. The cylinder has a structure that becomes slightly narrower toward the bottom. The bottle cap 12 has a wide opening at the bottom and a narrow opening at the top, and has a narrower hole than the upper narrow at the opening position, and fixes the cylinder at the bottom of the opening, The piston is fixed at the upper part of the opening. On the inner side of the bottle cap, a screw thread 6b for screwing with the bottle is provided. The pump head 11 has a pressing portion 16 at the top. The force applied in the pressing portion is transmitted to the lower piston portion 13. The inside of the pump head 11 is structured to be fitted with the discharge pipe 21 at the upper end of the piston portion. However, the protruding wall 17 is provided inside the pump head at the fitting position, so that the contents are not in close contact with each other. The pump head 11 is provided with a nozzle 18 having a discharge port for discharging contents.

  The piston portion 13 includes a coupling portion 20 that connects the piston portion and the cylinder 14, a discharge pipe 21 that is fitted to the pump head 11, a piston pipe 22, and a movable valve 23 that prevents backflow of contents. The inside of the discharge pipe is cylindrical so that the contents can be discharged, but the inside is shaped to be fitted with the piston tube 22. The discharge passage intermediate portion 21a is slightly narrower, and a metal ball valve 24 is housed in the piston pipe. This ball valve is idled at the upper part of the piston pipe 22, and when standing, the discharge path is blocked at a narrow position of the discharge path, but when the pump head is pushed, it is peeled off from the piston pipe, It has a structure for discharging objects. In the present invention, the ball valve is made of metal. By installing the ball valve, it is possible to prevent contact between the external air and the dentifrice, which is the contents, in a stationary state, and it is possible to prevent deterioration of the dentifrice. By making it metal, it is possible to prevent the ball valve from being moved downward with its weight and closed to be in contact with external air.

  The lower part of the piston pipe enters the cylinder. A stem 25 is provided inside the cylinder and has a plug structure inside the piston tube. A spring 26 is housed between the piston tube 22 and the stem 25. The piston tube 22 is fitted by the cylinder 14 and the coupling portion 20.

  When a force is applied to the pump head pressing portion 16, the piston tube 22 contracts the spring 26, and the dentifrice 4 stored in the piston portion 13 in advance is discharged through the discharge port 27. When the force applied to the pressing portion is removed after the discharge, the pump head 16 is pushed up by the extension force of the spring, and the dentifrice 4 is sucked up from the pump suction port 5, and the dentifrice 4 is filled inside the biston portion 13. At the start of use, the internal air may be removed by idly pushing until the dentifrice 4 is filled in the piston portion 13.

In the present invention, in the mounted state, the difference between the cylinder internal volume when the spring is extended (FIG. 2a) and the syringe internal volume when the spring is contracted (FIG. 2b) is 0.1 to 1 cm ³ . . By setting it as this volume, a suitable amount of dentifrice can be discharged. When the spring is extended, it is a state where no force is applied to the pressing portion in the attached state. Even in this state, since the fitted cylinder 14 and the piston tube 22 compress the spring 26, the spring 26 is normally contracted. However, in the attached state, this state is the state in which the spring is most expanded. Yes. The position at which the pump head stops by applying a force to the pressing portion 16 of the pump head 11 is when the spring is contracted. In the present embodiment, when the spring is contracted, the spring is compressed to the shortest. However, a stopper can be provided in the cylinder so that the spring does not contract any further. The cylinder internal volume refers to the internal volume from the cylinder upper port to the suction pipe. The entire internal volume of the cylinder is determined by the inner diameter and length of the cylinder 14, the spring 26, the volume of the piston tube 22 at the cylinder entry portion, and the volume of the stem 25, but the volume difference between the expansion and contraction of the spring is the contraction of the spring 26. It can be adjusted according to the degree. The approximate internal volume difference can be expressed by the following equation. The approximate is that when the shape of the cylinder 14 is slightly narrowed toward the lower part, or when the stem 25 is slightly narrowed toward the upper part, the calculated value and the actual This is because the values are slightly different.

(Internal volume difference) = {(Ya / 2) ² × π− (Yb / 2) ² × π} × (Xa−Xb) −V
Ya: Cylinder inner diameter Yb: Upper diameter of stem Xa: Total length of spring when extended Xb: Total length of spring when contracted V: Spring volume π: Circumferential ratio

  The stress of the spring 26 affects the pressing force of the pump head 11. In the pump container of the present invention, the pump pressing force is preferably set to 9 to 25N. The conditions for measuring the pressing force are: measurement temperature: 25 ° C., measurement speed: 200 mm / min. By setting this range, it is possible to hold the bottle with one hand and discharge the dentifrice with the force of one finger. The spring stress can be appropriately set so that the pump pressing force falls within this range.

Sectional area of the discharge port 27 of the pump head is preferably a 5 to 10 mm ^2. FIG. 3 shows a left side view of the bottle head. In the present embodiment, the discharge port 27 is a circle having a diameter (R) of 3 mm, and is about 7 mm ² . In addition to a circle, various shapes such as an ellipse, a square, a rectangle, and a rhombus can be used. By setting the discharge port to this value, the dentifrice 4 can be easily discharged and can be satisfactorily placed on the toothbrush.

  The pump container constructed in this way is a good preservation of paste-like toothpaste. In the present invention, the paste toothpaste includes toothpaste, gel toothpaste, cream toothpaste and the like. It is distinct from so-called liquid toothpaste. The paste-like toothpaste can be used without any particular limitation, but is preferably a paste-like toothpaste having a viscosity of 1 to 60 Pa · S, more preferably 4 to 20 Pa · S. Viscosity measurement was conducted under the conditions of a BH type rotary viscometer, rotor No. 5, at a drug temperature of 30 ° C., 20 rpm, and 2 minutes later. By setting it as this viscosity range, it can be set as the formulation which is easy to discharge from a pump and has shape retention property on a toothbrush. When the viscosity is less than 1 Pa · S, the viscosity as a pasty toothpaste is not sufficient and shape retention cannot be obtained. On the other hand, when the viscosity exceeds 60 Pa · S, the pressing force at the time of discharge becomes high, and it becomes difficult to discharge easily.
