不知道各位小夥伴們有沒有發現市面上很少有賣按壓式瓶裝的牙膏，90%以上的牙膏包裝都是軟管裝+盒裝。同時商家在牙膏的包裝上很少標明牙膏的一次使用建議量，因此往往出現牙膏擠出過量的尷尬情況。

一、設計成按壓式瓶裝存在諸多弊端

按壓式瓶裝的牙膏市面上也有不少，但是使用者的整體反饋並不好，無論是從商家還是使用者的角度來說都是利大於弊。

首先對於商家而言，按壓式的瓶裝設計成本上高於軟管包裝設計的，其次，牙膏的黏稠度很高，這樣就產生了兩個問題：一是為避免黏稠度較高的牙膏堵塞按壓管道，那麼管道的直徑就必須設計得更大，而這樣就會造成更多的浪費。二是如果想要減少浪費的問題就必須降低牙膏的濃稠度，這樣就會進一步提升製造成本，商家顯然是不願意的。

對於使用者而言：按壓式無法完全密封，出口也會有殘留，容易滋生髒東西，不衛生。牙膏畢竟是直接接觸口腔的東西，使用者必然會考慮其衛生性。

二、牙膏的一次使用量多少為佳？

幾乎所用的牙膏宣傳廣告上都是將牙膏在牙膏上擠又滿又多，這其實只是生產商為加快使用者使用牙膏的速度的手段而已。

成人使用牙膏，用量約在1/2牙刷頭的位置就足夠了，3歲以下的兒童應避免使用含氟牙膏； 4至6歲兒童應在大人指導下使用，每次牙膏的使用量約為豌豆大小。

牙膏的主要成分為摩擦劑、潤溼劑、增稠劑、芳香劑、防腐劑及其他化學物質等，幫助增加牙刷與牙齒間的摩擦力，刷牙重要的是“刷”，牙膏只是起輔助作用。牙醫認為，刷牙動作本身與牙膏作用的比率為9：1，所以與其糾結用什麼牌子的牙膏，不如認真地學一下刷牙的正確動作。

I don’t know if you guys have discovered that there are few toothpastes sold in push-type bottles on the market。 More than 90% of the toothpaste packaging is tube + box。 At the same time， businesses rarely indicate the recommended amount of toothpaste for one use on the packaging of toothpaste， so there is often an embarrassing situation of excessive toothpaste extrusion。

1. There are many disadvantages in designing a press bottle

There are many toothpastes in push-type bottles on the market， but the overall feedback from users is not good。 Both from the perspective of merchants and users， the advantages outweigh the disadvantages。

First of all， for the merchants， the cost of the press-type bottle design is higher than that of the tube packaging design。 Second， the consistency of the toothpaste is very high， which causes two problems： one is to avoid the high viscosity If the toothpaste blocks the pressing tube， the diameter of the tube must be designed to be larger， and this will cause more waste。 Second， if you want to reduce the waste problem， you must reduce the consistency of the toothpaste， which will further increase the manufacturing cost， and the merchants are obviously unwilling。

For users： the pressing type cannot be completely sealed， and there will be residues in the outlet， which is easy to breed dirt and unsanitary。 After all， toothpaste is something that directly contacts the oral cavity， and users will inevitably consider its hygiene。

2. What is the best amount of toothpaste?

Almost all the toothpaste advertisements used to squeeze the toothpaste on the toothpaste。 This is actually just a means by the manufacturer to speed up the user‘s use of toothpaste。 Adults use toothpaste， the amount of which is about half the position of the toothbrush head is enough。 Children under 3 years old should avoid using fluoride toothpaste； children 4 to 6 years old should use it under the guidance of an adult。 It is the size of a pea。

The main components of toothpaste are friction agents， wetting agents， thickeners， fragrances， preservatives and other chemical substances， which help increase the friction between the toothbrush and teeth。 The most important thing for brushing is “brushing”。 Toothpaste is only an aid effect。 Dentists believe that the ratio of brushing action to toothpaste is 9 to 1， so instead of entangled with what brand of toothpaste to use， it is better to learn the correct action of brushing。
