Description

  The present invention relates to a tube container with a cap in which a cap is attached to and detached from a tube container containing a viscous fluid such as toothpaste as a content by an opening and closing operation in a vertical direction by a user.

  A viscous fluid, such as toothpaste, is contained in a tube as a content at the manufacturing stage and covered with a cap to form a toothpaste product, and then put on a distribution / sales route.

  Toothpaste products use the toothpaste contained in the tube to remove and attach the cap when it is not in use. Today, the cap can be fitted and removed at the mouth of the tube with one touch for convenience. A so-called undercut fitting method has been developed and adopted that enables clean and simple use.

  5 and 6 illustrate the toothpaste tube 10 with the cap 18 that employs the undercut fitting method. FIG. 5A is a longitudinal sectional view of the main part of the pouring nozzle 14 and the cap 18, and FIG. 5B is a well-known inner state of the inner cylinder portion 24 when the cap 18 is viewed from the back side (the pouring nozzle 14 mounting side). FIG.

  As shown in FIGS. 5 and 6, the toothpaste tube container 10 has a small-diameter cylindrical discharge nozzle 14 gently connected to a distal end portion of a large-diameter tube container body 10 a via a tapered shoulder portion 12. In the pouring nozzle 14, a locking undercut 16 is formed on the peripheral surface on the base side.

  The cap 18 that opens and closes the pouring nozzle 14 is attached to and detached from the tube container body 10a by an opening / closing operation in which the user pulls the cap 18 up and down with respect to the tube container body 10a. The cap 18 is a disc-shaped cap top plate portion 20 and an outer cylinder portion 22 that is suspended from the periphery of the top plate portion 20 and pressed into contact with the tapered shoulder portion 12 of the tube container body 10a when the cap 18 is opened. The outer cylinder portion 22 has a gap that is suspended from the top plate portion with a gap and has a locking convex portion 24a at the inner lower portion, and protrudes from the shoulder portion 12 of the tube container body 10a when the cap is closed. On the base side of the outlet nozzle 14, an undercut (locking portion) 16 formed in a stepped unevenness is provided with an inner cylinder portion 24 into which the locking convex portion 24 a is fitted. That is, the cap 18 has a substantially double cylinder shape in which the outer cylinder part 22 and the inner cylinder part 24 hang from the top plate part 20.

  And the lower part of the inner cylinder part 24 is divided into a plurality of parts by cutting a plurality of vertical slits 26 (substantially a shape in which a plurality of strips are lowered), and an undercut of the pouring nozzle 14 is formed inside each part. The protrusions 24a for locking to 16 are continuously formed to be uneven.

  When the user pushes the cap 18 into the dispensing nozzle 14, the inner cylinder portion 24 is expanded elastically deformed, and each locking projection 24 a gets over the undercut 16 and is reduced in diameter, and is fitted into the undercut 16. The cap 18 is fixed to the dispensing nozzle 14 by being locked. On the other hand, when the cap 18 is pulled up, or the lower portion of the cap 18 or the tube container shoulder 12 is pushed and shrunk with fingers and the cap 18 is pushed up from the shoulder, the locking convex portion 24 a of the inner cylinder portion 24 is removed from the undercut 16. This removes the cap 18 from the tube container 10. Such a cap fitting method is referred to as an undercut fitting method.

  With regard to caps of this type of undercut fitting method, Japanese Utility Model Publication No. 62-29403 (Patent Document 1), Japanese Utility Model Publication No. 01-3483 (Patent Document 2), and Japanese Utility Model Application Publication No. 03-11165 (Patent Document). 3) etc. are shown.

  Here, the conventional tube container is a compression resin molded product and has poor molding accuracy (bore diameter, collapse, etc.), and thus the degree of adhesion with the cap tends to deteriorate. For this measure, as shown in FIG. 5, the conventional tube product is formed by extending an inner ring 28 from the inner cylinder part 24 on the lower surface of the top plate part 20 of the cap 18 to the entire circumference from the inner circumference part. Yes. When the cap 18 is fitted into the dispensing nozzle 14, the inner ring 28 is fitted into the tip 14 a of the dispensing nozzle 14, and the liquid is sealed between the tip 14 a and the cap 18. To prevent leakage. In order to guide the inner ring 28 to the pouring nozzle 14, a plurality of ribs 30, 30.. Has been.

  However, in the above-described conventional tube product, the contents (denoted by reference numeral 32) that remain attached between the top plate portion 20 and the inner ring 28 gradually accumulate as the number of times of use is increased after the start of use.

  As a result, the contents 32 are confined to the outer ring inner portion 28 by the fitting of the pouring nozzle (tube mouth portion) 14, and the inner cylindrical surface 24 becomes dirty from the inner peripheral surface to the entire inner peripheral surface. It is pushed out through a gap 34 between 30, 30. Due to repeated cap attachment and removal, there is a problem that the appearance deteriorates, such as protruding out and remaining around the pouring nozzle 14 and the shoulder 12. That is, as shown in FIG. 5B, the content 32 fills the inner peripheral portion of the inner cylinder portion 24 and hides the ribs 30, 30... With the cap 18 removed.

Further, if the contents remain between the inner cylindrical portion 24 and the inner ring 28 of the cap 18, when the dispensing nozzle 14 is pushed between them, the dispensing nozzle 14 must be pushed in while pushing out the contents. It is difficult to fit. Furthermore, when the remaining contents engage with the locking protrusion 24a of the inner cylinder portion 24 with the undercut 16 of the dispensing nozzle 14, it becomes difficult to fit, and the user fits the cap into the tube. However, there is a problem that the click feeling is not obtained and the usability is deteriorated.
